Patent DE-2542136-A1 (DE)
Title: Heat exchanger for air technology applications - having rhombic shaped plates formed into bundle
Inventor: MOSER KARL DIPL ING
IPC: F28D9/00
Filed: 1975-09-22
Abstract: Plate type heat exchanger has effective heat transfer surfaces formed from equal sided parallelograms (rhombus) with height H = Bx n where B is the width and n >1. The rhombic pockets are formed from individual metal sheets whose ends are bent and folded in conventional fashion. The rhombic pockets are formed from thin metal plates with only the cut shape. the formed plates are then inserted into each other by means of stays and folds across them so as to inter link them. This forms airtight pockets or passages. The sheets can be jointed by a suitable bonding agent e.g. metal bond. Distance pieces can be inserted and bonded in between the plates. The outer housing is mounted along the edges by means of pressure screws. Used esp. for heat recovery from exhaust air streams in air technology. Rectangular exchangers of this type are common and satisfactory. However in many applications, available depth (cross sectional width) is a significant limitation. The rhombic, cross section gives a more balanced heat transfer area.

Title: Digital phase locked loop for navigation systems - is designed specially for microwave systems such as TACAN and includes a/d converter and sequence register
Inventor: BJEREDE BJORN ERIK
IPC: G01S1/44
Filed: 1975-12-19
Abstract: The phase-locked loop generates clock pulses synchronised with the passage through zero of an input data signal, e.G. for use in navigation systems. An A/D convertor continuously converts the input signal into a digital signal which is checked and stored by a memory when it receives a clock pulse. When a given digital signal count is reached an instruction sequence register reads out the count in synchronism with the zero passage of the input signal and generates a carry pulse at the end of the count. The carry pulse is fed to a pulse generator to produce a synchronous output clock pulse which leads or lags the zero passage of the input signal by the counting time of the instruction sequence register. A circuit feeds the output clock pulse to the memory which ensures this pulse and a second output clock pulse are synchronized with the zero passage of the input signal.

Title: Low consumption electromagnetic drive - uses magnetic repulsion and attraction achieved by alterations in field strength and pole reversal
Inventor: HILBERS HEINZ
IPC: H02K7/065
Filed: 1976-06-10
Abstract: The drive achieves high velocities with the minimal use of electrical energy. The forseen applicators are in air and space travel where high electrical current sources are undesirable due to their high mass. The drive employs fixed (E1) and moving (E2) magnets. The fixed magnets are attached to the body to be driven whilst the moving magnets run in guides. At the start of the cycle both have the same magnetisation direction. The moving magnets are then reversed and increased in strength, the repulsion causing the accelerating force on the body. The moving magnet field strength is increased so that as they approach each other they again repell. The fixed magnet field strength is reduced and the moving magnets return to their starting position.
