20090025229 | Dry Shaver with Pivotal Shaving Head - A dry shaver with a housing features a drive motor and a shaving head connected to the housing for pivotal movement about a pivot axis. The shaving head mounts at least two shaving systems, each comprised of an outer cutter and associated under cutters. The under cutters are adapted to be driven in an oscillatory linear motion relative to the outer cutter. The at least two under cutters are mounted respectively on separate oscillatory elements in the shaving head. The oscillatory elements are each connected to the drive motor via drive elements and are driven in mutually opposite directions. | 01-29-2009 |
20120005900 | ELECTRICALLY OPERATED SHAVER WITH REPLACEABLE CUTTING DEVICE - The invention relates to an electrically operated shaver with at least one upper blade attachable to a shear head frame by means of a removable frame, on the underside of which lies a linearly oscillating lower blade. The lower blade is connected via a clutch engagement with an oscillating bridge mounted on either side on the shaver by resilient arms. The oscillating bridge is also connected to the drive shaft of an electric motor via a gear mechanism, so that when the motor is running, the oscillating bridge, and thus also the lower blade, is set in linear reciprocating motion. According to the invention, the resilient arms of the oscillating bridge are arranged on the removable frame. In this way, the oscillating bridge which often wears out quickly, can also be replaced when the cutting device is replaced. This prevents malfunction and potentially high repair expenses, thus reducing costs. | 01-12-2012 |
20140290452 | Male Dry Shaver - An electrically driven shaver comprises a housing and at least one hair cutting element that is driven by an electromotor. A thermoelectric skin cooling element and the electromotor are electrically operable by a microcontroller and an on/off switch which is electrically connected with the microcontroller. The microcontroller is adapted to activate and deactivate operation of both the electromotor and the skin cooling element. The skin cooling element is located adjacent to the hair cutting element. The microcontroller is adapted to immediately deactivate operation of the electromotor and relative to that to deactivate operation of the skin cooling element at later point of time, both in response to the “off” actuation of the same on/off switch. | 10-02-2014 |

20090133834 | Radial Block Copolymers and Adhesives Based Thereon With Improved Die-Cutting Performance - Improved adhesives are provided through the use of styrenic radial block copolymers, containing at least 40 wt % diblock copolymers, the adhesives have improved adhesive properties and a reduced elastic behavior under die-cutting conditions. Compared to conventional linear block copolymers of similar molecular weight, radial copolymers offer higher holding power and lower melt viscosity for the adhesive. They therefore contribute to an improved balance between processability and end-use properties. | 05-28-2009 |
