Title: Compression ignition engine fuel injector pump assembly - has valve components with precision chamfer designed to prevent wrong assembly
Inventor: LEONBERGER HANS
IPC: F02M59/46
Filed: 1978-01-17
Abstract: The pressure relieve valve is guided in a valve carrier. This relieving valve slides longitudinally. This arrangement is used in injection pump for air compressing internal combustion engines. The valve design ensures that the valve carrier cannot be assembled in wrong position. The bore on the chamfer (15) opposite the valve seat (14) has an aperture which interrupts the total width of this chamfer (15). This chamfer is precision machined and the design ensures that it can be inspected optically and also for technical functioning. A fitter will immediately recognise the attitude in which the valve carrier is to be placed into the pump element. On wrong assembly the opening will leak fuel and demonstrate its wrong attitude.

Patent DE-2941702-A1 (DE)
Inventor: MOLNAR NIKOLAUS DIPL PHYS
IPC: H04J3/06
Filed: 1979-10-15
Abstract: In transmission of information via satellite, it has proved to be necessary to insert pauses into the information flow, because of the different propagation times of the electromagnetic waves for the various stations. For this purpose, a synchronisation device for a PCM system is specified which has at least one channel on which at times no signals are received. Each data signal packet includes a number of precursor pulses, from which the data signal frequency is derived. To synchronise the data signals (Sd) with the clock signals (Sc) of the PCM system, a main memory (DS), into which the data signals are written cyclically at the data signal frequency and from which they are read cyclically with another clock signal (Sc2), is present. A reset circuit (RS) gives a reset pulse (Sr), using which the first pulse of the series of input pulses which are cyclically written into the main memory is in each case phase shifted by a few cycles compared with the starting pulse of the series of output pulses which are cyclically read from the main memory. <IMAGE>

Title: Proximity sensor encapsulation - in silicone rubber mould by polyurethane foam injection
Inventor: SCHALLER WERNER DIPL ING
IPC: H05K13/00
Filed: 1979-12-24
Abstract: Electronic components, e.g. proximity sensors and modules, are encapsulated by injecting into the split mould, produced from casting resin, a multi-component plastic material which is converted into a foam, esp. integral polyurethane foam, and forms a solid coating when the pores break up on contact with the mould. A retarding agent ensures that foaming is delayed until the liq. material has filled the mould. Glass fibres can be blown into the mould before the injection to form a deposit on the walls. This is a simple low-cost process which permits thinner walls and requires little fettling.
