Inventor: ZOLLNER ALFRED
IPC: B41J2/045
Filed: 1997-10-08
Abstract: The print head has a multitude of adjacently arranged channels with piezo-electrical shear converters.

Abstract: A medical electrical lead having a multi-ple conductors located within an elongated lead body (10) which is provided with multiple con-ductor lumens (100, 102, 104) each containing a conductor (112, 114) and with at least one compression lumen (106, 108, 110) which does not contain a conductor. The conductor lumens (100, 102, 104) are spaced from one another by a first, minimum spacing and the compression lumen (106, 108, 110) or lumens are located in-termediate the conductor lumens and are spaced from the conductor lumens by a second, min-imal spacing of less than said first minimum spacing. The centers of the compression lu-mens (106, 108, 110) are located along lines which pass through both the center of a con-ductor lumen and the center of the lead body.      The arrangement of the conductor and compres-sion lumens enhances the lead's ability to sur-vive crushing forces such as applied by the first rib and clavicle.

Patent CA-2219989-A1 (CA)
Inventor: HARDT MANFRED
IPC: H02P7/00
Filed: 1996-04-04
Abstract: The invention relates to a device for fitting rivets, buttons or the like in textiles or the like with a ram driving the rivets, the upward and downward movement of which is controlled by the co-operation of the upper end of the ram with a cam rotated by an electric motor. When a switch or the like is operated, the device performs a series of fitting movements, the electric motor (39) which runs at a preset angular speed being stopped briefly at the top dead centre position of the ram (24) to reduce the beat frequency of the ram stroke. To this end the control unit switches the drive motor (39) off at the top dead centre position of the ram for a pre-programmed dead time and switches it on again and actuates a brake especially during the dead time.

Patent CA-2230200-A1 (CA)
Inventor: LAUZON JOCELYN
IPC: G02B6/02
Filed: 1998-03-27
Abstract: A method and an apparatus to photoinduce a grating or other type of modulated refractive index change in a photosensitive optical medium such as optical fiber. The resulting grating has a variable and controllable intensity profile and average value of the index change. The modulated refractive index change is photoimprinted in the medium i.n a series of writing steps, each comprising exposing a segment of the medium to a writing beam for a predetermined exposure time. To change the modulation intensity from step to step, the angle of incidence of the writing beam is dithered for an appropriate fraction of the exposure time at each step. This allows to control the amount of incident light on the medium for each step. If the exposure time is the same for each writing step, the average value of the index change may be kept constant avoiding undesired structure in the grating frequency response.
