Title: Apparatus and method for refilling a container with a more or less viscous material
Inventor: HELMUT ULMER
IPC: A47K5/12
Filed: 1991-09-24
Abstract: ABSTRACT      The disclosed apparatus is suitable for refilling a container with a more or less viscous material.  The apparatus includes a support frame, a storage container affixed thereto and an intermediate reservoir which is affixed to the support frame and extends away from the storage container.  A mouthpiece is mounted to that end of the intermediate reservoir which is remote from the storage container. The apparatus further includes a discharge valve at the end of the mouthpiece directed away from the storage container and a closure valve positioned in the intermediate reservoir.  These valves are opened and/or closed by way of a mechanical coupling when the container to be refilled is pushed against a first piston longitudinally movable in the mouthpiece.  The apparatus operates practically independent of the viscosity of the material to be refilled and generally works without maintenance for a long period of time, since the functioning of the valves is mechanically controlled and not determined by the pressure conditions present in the intermediate reservoir.

Title: Shock resistant lighting fixture
Inventor: WAYCASTER BRAD
IPC: H01R33/08
Filed: 1991-11-19
Abstract: ABSTRACT OF THE DISCLOSURE    A socket arrangement for a light fixture holding a tubular lamp having contacts on opposite ends, providing a fixed socket opposite a spring loaded socket with a lamp maneuvering cavity adjacent to the fixed socket, allowing a tubular lamp to be installed nearly straight-in to the sockets, and preventing electrical shock.  By providing the maneuvering cavity opposite the spring loaded socket, a first end of a tubular lamp can be maneuvered into the cavity to allow an opposite end of the tubular lamp to insert into the spring loaded contact, and further insertion causes compression of the spring loaded contact, which retracts the first end out of the maneuvering cavity a sufficient distance to swing the first end through a slot formed in a side of the fixed socket and into the fixed socket, whereupon the spring loaded socket expands to resiliently hold the tubular lamp between the two sockets.  Handling exposure of a free end of a tubular lamp while an opposite end is making electrical contact with a terminal is thus minimized during relamping.

Patent CA-2060117-A1 (CA)
Inventor: BLAUVELT HENRY A
IPC: H04B10/2557
Filed: 1992-01-28
Abstract: An electronic circuit provides a linear output from an amplitude modulated transmission device such as a semiconductor laser which has inherent distortion. The distortion of the nonlinear device is compensated by applying a predistorted signal equal in magnitude and opposite in sign to the distortion introduced by the nonlinear device.  The input signal is split into two or three paths with primary part of the signal applied directly to the device, with a time delay to compensate for delays in two secondary paths.   One secondary path generates even order intermodulation products   and   the   other   generates   odd order intermodulation products.   These are recombined with the primary signal in proper phase and amplitude for cancelling  distortion  in  the  output  device.    A distortion generator in each secondary path generates adjustable amplitude intermodulation signals.  A tilt adjustment is made to compensate the amplitude of the predistortion for frequency dependence of the amplitude of the distortion.  Phase of the distortion signal is adjusted to be  in proper phase relation with the distortion of the device.  In the even order path there are  means   for   adjusting  predistortion   at   an intermediate  frequency  so  that  the  distortion  is cancelled  near  the  upper,  lower  and  intermediate portions of the frequency range of the device.   If desired, set points of the predistorter may be adjusted automatically.

Title: Method of determining a temporary subscriber number (tmsi) in a subscriber data base
Inventor: PFUNDSTEIN MATTHIAS
IPC: H04Q7/20
Filed: 1992-06-03
Abstract: Subscriber data bases with large subscriber-data fluctuations require special strategies to ensure optimum utilization of the available storage space while keeping access times as short as possible. In addition, subscriber anonymity is to be ensured. A method is provided for assigning a memory location to each subscriber via a temporary subscriber number (4-byte TMSI).      The invention proposes an internal structure for the TMSI which consists of several logically independent elements which, on the one hand, permit as large an addressing range as possibly and, on the other hand, preclude any confusion of data records or any identification of the subscriber. In addition, the TMSI is constantly changed. With a 32-bit TMSI, up to 10 6 subscribers can be unambiguously addressed.
