Title: Activating telephone exchange night switch - using central memory to store allocations of switchboard positions to subscribers
Inventor: GERICKE HARALD
IPC: H04Q3/62
Filed: 1989-09-29
Abstract: An auxiliary telephone exchange station has a central controller (C,C), a central memory (MEM), a switchboard position (UP) associated with each of a limited number of subscriber groups comprising one or more telephones (VF), and a priority line circuit device (TLNA) to demand activation of the night switch.  The controller (C,C) checks the demand by interrogating the memory (MEM) and connects up the priority line device (TLNA) with a target device (TLNE) by selecting the corresponding number. The central memory (MEM) stores the allocations of switchboard position (VPi) to subscriber devices.  The controller (CC) interrogates the memory (MEM) and activates the appropriate night switch when the switchboard position (VP) of the calling subscriber (TLNA) and the target (TLNZ) correspond. USE/ADVANTAGE - Enables correct activating of night switch of several switchboard positions in telephone exchange for several independent subscriber groups.

Title: Implant for e.g. stiffening bones and anchoring prostheses - consists of polymer and/or copolymer in which filler particles are at least partially embedded
Inventor: DRAENERT KLAUS
IPC: A61L24/00
Filed: 1990-09-19
Abstract: Implant material consists of polymer and/or copolymer and filler particles so that the polymer and/or copolymer at least partially encloses the filler particles. USE/ADVANTAGE - The implant material can be used to anchor prostheses components in bones and to stiffen the bones and to form pins and screws and implants for anchoring screws e.g. in compound osteosyntheses. The filler particles can be X-ray contrast agents and antibiotics and do not weaken the mechanical strength of the filler material and cause no defects. The particles are homogenously and reproducibly distributed in the material. Uniform release active ingredient in relatively high concns. can be achieved. The low monomer content reduces the temp. during hardening, greatly increases the mechanical stability of the material and ensures that X-ray contrast agent is far more uniformly distributed. The filler particles give the material porosity. (4pp Dwg.No.0/0)

Title: Stopper mounting - has ceramic press unit within stopper to take treaded end of carrier tube and resist distortion or damage
Inventor: HILL DEREK
IPC: B22D41/18
Filed: 1990-12-17
Abstract: The assembly to give a sealed mounting to hold a fireproof ceramic stopper in place at the carrier tube of a metallurgical vessel, has a pressed-in section (3) of a fireproof ceramic material with an inner threading to take the carrier tube passing through the end face of the stopper (1). A ceramic bonding is between the press section (3) and the stopper (1) at their butting surfaces (8, 9). The sealing is provided by a compressible seal (17) at the end face (5), which is compressed against the end surface (5) by a flange (16) fixed to the carrier tube (12). The seal (17) is a ceramic fibre material. A further seal is formed by a ring surface (11) in the interior zone (2) of the stopper (1), worked either at the press section (3) or the stopper (1). The end of the press section (3), away from the end face (5), has an inner collar (10) to form the sealing ring surface (11) for the end (15) of the carrier tube (12) away from the end face (5), to press against the ring surface (11) directly or through a ring seal. The ring surface (11) is conical, and the sealing ring is of metal. The ring surface worked into the stopper (1) is near the ned of the press section (3) away from the end face (5). A pin (20) passing through the carrier tube (12) flange (16) into a drilling (21) at the end face (5) of the stopper (1) prevents rotation between the carrier tube (12) and the stoper (1). The pin (20) is parallel or at an angle to the longitudinal axis (L) of the carrier tube (12), or an inserted pin to lock against relative rotation is radial to the longitudinal axis (L) of the carrier tube (12). Part of the outer shape of the press section (3) is conical (6) to the end face (5) of the stopper (1), passing into a cylindrical shape (7). The cross section of the press unit (3) is round or oval, with a profiled outer periphery. The press section (3) is of a ceramic material containing about 77% SiC and about 20% of Si3N4. ADVANTAGE - The press unit in the stopper assembly has a firm seating and, as it is of a similar material to the stopper, it does not distort through heat. The carrier tube remains undamaged and is easily screwed into place.

Title: Jigging conveyor with phase-sensitive trigger pulse generator - substitutes ramp generator for normal modulator of electromagnet drive pulse width to enable rapid starting
Inventor: SCHOELLMANN WOLFGANG
IPC: B06B1/02
Filed: 1992-01-07
Abstract: The conveyor includes an elastically movable chute (5) on springs (3) which is vibrated by an electromagnet (7) driven by the output stage (23) of a pulse generator (11) with an opto-isolator (21). Trigger pulses are produced by a shaper (15), amplifier (17) and differentiator (19) at instants when a contactless detector (13) signals a predetermined phase of the vibration. The driving pulse width is controlled by a regulator circuit (25) which holds the amplitude of vibration at a predetermined desired value. For starting, this regulator is inhibited (37) and a special ramp generator (39) runs-up the pulse width and vibration amplitude the initial trigger pulse being generated by noise amplification (17). ADVANTAGE - The driving signal frequency is easily adapted automatically to the eigenfrequency of the conveyor within wide limits of variability, esp. at start-up.
