20090129894 | Bucket bale spear - A bucket bale spear bolts together upon a frame, that slips upon the cutting edge of a bucket, and then one bolt secures the frame to the bucket. The frame receives a spear and two balance spikes upon a bracket. A centered tube accepts the spear and secures it with a transverse bolt. The tube provides additional bending resistance for the spear at less weight than a proportional length of spear. The balance spikes also bolt to the frame. The frame, spear, and balance spikes can be shipped and merchandised compactly. At the farm or the ranch, the bucket bale spear assembles readily with hand tools. | 05-21-2009 |
20090129895 | Skid steer bale spear - A skid steer bale spear has a single member, or cross tube, to which joins at least one spear and balance spikes. The member then has plates proximate each end welded to the member for connection to a tractor or skid steer loader following the spacing and orientation for the Universal Skid Steer Quick Attach. Additionally, this skid steer bale spear includes a rollback angle to the spear, foot grips, backstops, and detachable spears and spikes. This skid steer bale spear uses less resources, capital, labor, and materials for manufacturing. The member, spear, and balance spikes can be shipped and merchandised in a compact form. At the farm or the ranch, the skid steer bale spear assembles in minutes with hand tools and readily connects to a tractor or loader. | 05-21-2009 |
20110203062 | Rotary broom with gearbox drive - A rotary broom mounts upon a slotted plate that pivots upon a double gearbox. The broom has bristles upon an axle within a shield that receives power from a chain drive that receives its power from a driveline from a top gear box. The top gearbox orients in the direction of the chain driveline and delivers its power through an output shaft. The top gearbox joins to a slotted plate that turns in the same direction as the broom. The top gear box receives its power through an input shaft perpendicular to the output shaft. The top gearbox input shaft extends downwardly and becomes the output shaft of the bottom gearbox. The bottom gearbox has an input shaft that connects to a power take off. This rotary broom receives rotational power, rotates it 90° upwardly, then rotates it 90° downwardly and at an angle laterally to drive the broom. | 08-25-2011 |
20150197961 | Post Driver Having Reverse Twisted Spring Assembly - A post driver having a reverse twisted spring is disclosed which comprises a carriage, a driving ram which is movable relative to the carriage, a hydraulic cylinder assembly having a threaded hydraulic cylinder rod extending out of a first end of the hydraulic cylinder assembly, the threaded hydraulic cylinder rod capable of movement out of the hydraulic cylinder assembly and retracted back into the hydraulic cylinder assembly, the threaded hydraulic cylinder rod being connected to the driving ram, the hydraulic cylinder assembly having a second end being connected to the carriage, and a spring assembly comprising an outer spring and a reverse twisted spring within the outer spring, a first end having a screw-in plug, a threaded rod extending out of the screw-in plug in the first end with the threaded rod being connected to the driving ram, and a second end connected to the hydraulic cylinder assembly. | 07-16-2015 |

20090215345 | PARTICLE-CONTAINING FIBROUS WEB - A porous sheet article comprising a self-supporting nonwoven web of polymeric fibers and at least 80 weight percent sorbent particles enmeshed in the web, the fibers having sufficiently greater elasticity or sufficiently greater crystallization shrinkage than similar caliper polypropylene fibers and the sorbent particles being sufficiently evenly distributed in the web so that the web has an Adsorption Factor A of at least 1.6×10 | 08-27-2009 |
20100108067 | RESPIRATOR FLOW CONTROL APPARATUS AND METHOD - A respirator has a shell that defines a breathable air zone for a user wearing the respirator. An air flow control system for the respirator has an air delivery conduit within the shell of the respirator, a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit, and a valve actuator outside of the shell of the respirator. The valve actuator is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member. | 05-06-2010 |
20100154805 | FLAT FOLD RESPIRATOR HAVING FLANGES DISPOSED ON THE MASK BODY - A flat-fold, filtering, face-piece respirator | 06-24-2010 |
20100221159 | LOW PRESSURE DROP, HIGHLY ACTIVE CATALYST SYSTEMS USING CATALYTICALLY ACTIVE GOLD - Highly active, low pressure drop catalyst systems. Catalytically active material is provided on at least a portion of the channel sidewalls of a body comprising one or more flow-through channels. The channel sidewalls preferably bear a charge, e.g., an electrostatic or electret charge, to help adhere the catalytically active material to the sidewall. The catalytically active material preferably includes gold provided on a particulate support, and PVD techniques are used to deposit catalytically active gold onto the support. Optionally, the gold-bearing particulates may be charged as well in a manner to facilitate attraction between the particulates and the sidewalls. | 09-02-2010 |
20110234374 | DETERMINING CONDITIONS OF PERSONAL PROTECTION ARTICLES AGAINST AT LEAST ONE CRITERION - The present disclosure is particularly adapted for determining whether the condition of personal protection equipment PPE articles satisfies at least one criterion. A method and system provide at least one predetermined criterion that governs use of the PPE article in a working environment; a PPE article is configured with a smart tag, and a sensing device is provided that is configured to sense data in a working environment related to the predetermined criterion. Acquired data from the sensing device and the smart tag are processed in a data processing system to determine whether the condition of the PPE article satisfies the at least one predetermined criterion. | 09-29-2011 |
