| 20080308574 | Optically keyed dispenser - A method of controlling operation of a mechanism, preferably a dispenser, having a removable component comprising the steps of measuring electromagnetic radiation passing through a wave guide carrying at least in part on the removable component and permitting operation of the mechanism only when the measured electromagnetic radiation corresponds with one or more pre-selected parameters. Preferably, the method involves directing emitted electromagnetic radiation with pre-selected input parameters selected from a plurality of input parameters. | 12-18-2008 |
| 20090008408 | Optically keyed dispenser - A method of controlling operation of a mechanism, preferably a dispenser, having a removable component comprising the steps of measuring electromagnetic radiation passing through a waveguide carrying at least in part on the removable component and permitting operation of the mechanism only when the measured electromagnetic radiation corresponds with one or more pre-selected parameters. Preferably, the method involves directing emitted electromagnetic radiation with pre-selected input parameters selected from a plurality of input parameters. | 01-08-2009 |
| 20090032552 | Split engagement flange for soap dispenser pump piston - A liquid soap dispenser is disclosed having a permanent housing which permits simplified insertion and replacement of disposable fluid reservoirs. The housing includes an actuator assembly which is cycled by a lever between first and second positions. The actuator assembly is configured to couple to a piston element of a piston pump carried on the reservoir so that when cycled, the piston element is actuated in sliding movement to dispense a quantity of fluid. The piston element includes resiliently deformable fingers which act to secure the piston element to the actuator assembly for sliding movement therewith. If, on insertion of a replacement reservoir, the reservoir is positioned uncoupled from the actuator assembly, on first cycling of the actuator assembly the fingers deform to permit movement of the actuator assembly relative to the piston element and move towards a coupled orientation. In the coupled orientation, the fingers return to an undeformed configuration securing the piston element to the actuator assembly. | 02-05-2009 |
| 20090045221 | Touchless optically controlled dispenser - An automatically controlled apparatus whose operation is controlled at least in part by the input of a signal that an object is sensed in a selected positioned relative the apparatus, the apparatus having an emitter to emit electromagnetic radiation and a sensor to sense electromagnetic radiation emitted by the emitter which is reflected off an object suitably positioned relative the apparatus, the improvement comprising a carriage member mounted to the apparatus for relative pivoting about a pivot axis, the emitter and sensor carried by carriage member, the emitter being generally directional emitting radiation to emanate outwardly from the emitter generally along a longitudinal emission axis, the sensor being generally directional and sensing radiation which emanates generally along a longitudinal sensing axis terminating in the sensor, the emission axis and the sensing axis generally disposed in a common plane which includes the horizontal axis. | 02-19-2009 |
| 20090145296 | Angled slot foam dispenser - The present invention provides a piston pump for liquid in which a sump is defined in a chamber into which sump liquid in the chamber flows due to gravity. A passageway leads from an outlet of the sump out of the chamber to a dispensing outlet. The dispensing outlet is at a height below the height of the sump outlet and fluid to exit the sump flows from the sump outlet upwardly in a first portion of the passageway to a height above the sump outlet then downwardly to the dispensing outlet. The chamber and its sump is defined between a piston chamber-forming member defining the chamber to be downwardly opening and a piston forming element axially slidable in the chamber. | 06-11-2009 |
| 20090200340 | Rotary foam pump - The present invention provides a positive displacement rotary vane mixing pump with an air inlet and an inlet for foamable fluid and an outlet from a discharge sector of the pump for discharging a mixture of air and liquid to a foam generator. | 08-13-2009 |
| 20100140297 | Engagement flange for fluid dispenser pump piston - An improved arrangement for removably coupling a movable element of a piston pump to an actuator mechanism with the movable element including a resilient member which prevents radial movement of the movable element relative a catch member of the actuator mechanism from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration. | 06-10-2010 |
| 20100147879 | Photochromic optically keyed dispenser - A removable and replaceable keying component which is required for operation of a mechanism and which component includes a waveguide having a photochromic portion. A method of controlling operation of a mechanism, preferably a dispenser, having a removable component comprising the steps of measuring electromagnetic radiation passing through a waveguide carrying at least in part on the removable component and permitting operation of the mechanism only when the measured electromagnetic radiation corresponds with one or more pre-selected parameters. Preferably, the method involves directing emitted electromagnetic radiation with pre-selected input parameters selected from a plurality of input parameters. | 06-17-2010 |
| 20100163580 | Engagement flange for removable dispenser cartridge - An improved arrangement for removably coupling a replaceable cartridge to a housing of a dispenser with the cartridge including a resilient member which prevents radial movement relative a catch member of the housing from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration. | 07-01-2010 |
| 20100186156 | Foam odor plug for urinals - A urinal discharge pipe assembly comprising a discharge pipe having a passageway therethrough from an inlet in communication with a urinal discharge outlet and an outlet in communication with a urine disposal system, a foam dispensing device having a foam outlet open into the passageway for discharge of an allotment of foam into the passageway between the inlet and the outlet adequate to form a temporary foam plug across the passageway blocking the passageway. | 07-29-2010 |
| 20110014076 | Draw back push pump - A piston pump dispenser having a reciprocating piston pump arrangement which in a dispensing stroke dispenses fluid from an outlet and in a charging stroke draws fluid from a reservoir and also draws back fluid from the outlet. | 01-20-2011 |
| 20110079615 | Convertible peristaltic and piston pump dispenser - A dispenser for flowable material adapted for engagement and for dispensing fluid from either a replaceable piston pump reservoir unit comprising a reservoir bottle and a piston pump or a replaceable peristaltic pump reservoir unit comprising a reservoir bottle and a deformable tube member. | 04-07-2011 |
| 20110132933 | Piston with frangible piston stop - A piston pump assembly in which a piston-forming element to be received in a piston chamber of a piston chamber-forming member carries a removable stop flange member which may be secured to the piston chamber-forming member to provide a retention stop to prevent the piston-forming element from being removed from the piston chamber. | 06-09-2011 |
