Patent DE-4223674-A1 (DE)
Inventor: KOCHMANN MICHAEL
IPC: G06F3/023
Filed: 1992-07-17
Abstract: To operate input devices such as magnetic card readers (22) or keyswitches (23) for personal computers (11), these are connected to the keyboard processor (18) and are activated by previously unused control codes. The data of the input devices are recoded into data for possible key operations and the data transmission to the personel computer is initiated by the code for a non-existent key. As a result, the keyboard controller in the personal computer need not be reprogrammed, and the function of the input device cannot be simulated via the keyboard.

Title: Imparting pattern to article while injection moulded - by using patterned film, heating it by hot plate with gas between and between mould tools, closing mould and injecting shot into cavity
Inventor: OHNO SHINPEI
IPC: B29L9/00
Filed: 1993-04-28
Abstract: Pattern is produced on articles while they are being injection moulded. In the process a film bearing the pattern is placed in a position between a male and female mould and is heated until softened by means of a heater plate; the film is transferred to an inner face of the female tool; the heater plate is withdrawn and the male and female so as to form the article and to impart/bond the film on to its surface. In the heating stage only an outer part of the film is held at a distance from the heated surface so as to prevent the film from coming into direct contact with the heated face. The injection gate (4) is in the fixed male mould tool (1) opposite the moving female tool (2); the latter (2) has an air venting hole (8) connected to a vacuum pump (not shown). The heater plate (9) is positioned at a set distance from the outer peripheries of the two tools (1,2) and can be moved vertically into/out of this position. The heater plate (9) is positioned as required beforehand to take up the patterned film (X) and move to between the tools (1,2). The film absorbs heat during that movement and softened thereby so that, when the film is next released in position it is taken up by the female tool face (2a). ADVANTAGE - The procedure is free from the usual current problems (trapping air between film and article). The pattern is free from any faults transferred from the surface of the heater plate.

Patent DE-4343612-A1 (DE)
Title: Cervix elasticity determn. method for detecting premature birth
Inventor: BLUECHER UWE DIPL ING
IPC: G01D5/12
Filed: 1993-12-16
Abstract: The method involves using a force sensor (1) with a measurement ring (2) round it. The sensor is linked to a force recorder (3) and the ring is fitted to a plunger (5) with an axial movement to register path movement. Magnets (8,9) can either be both permanent or a permanent magnet with a DC energised electro-magnet.  The measurement ring is pressed with a constant force against the material under test. The distortion of the material is measured by the force sensor which registers the reassertion force. Initially, from a start position, the sensor has applied to it a magnetic force. The relative movements between the ring and sensor are measured inductively, via a soft iron core (11) inside an electric coil (12), to give a difference reading to a microprocessor. A preloading is applied by the ring against the material, the loading having a value not equal to zero. A number of readings are made at different points to give a mean value.

Title: Transmitter synchronisation system for clocked bus system
Inventor: SCHMIDT WERNER
IPC: H04L12/40
Filed: 1994-02-19
Abstract: The synchronisation system allows transmission of packets of information between stations (ZE1,..ZEn) connected to a clocked bus system (BUS), using a single synchronisation procedure for synchronising the transmitters of all the stations, prior to transmission. A resetting information is detected by the receiver at each station to trigger a start counter and an operating counter, the station with the shortest time delivery time delivering a synchronisation identification (SY1) to the bus system received by all other stations, the transmitter of the first station synchronised with receiver. The time difference between the received synchronisation indication and that provided by the station with the next shortest time delivery is used to synchronise the transmitter at this station, the process repeated until all the transmitters are synchronised.
