Title: Steam turbine waste heat recovery circuit - has part of heat exchange medium passed through condenser driven by turbine
Inventor: JAKOB FRITZ
IPC: F25B30/02
Filed: 1976-11-13
Abstract: Waste heat from a steam turbine is sensed by employing a compressor (2) mounted on the drive shaft of the expansion turbine (1). This is connected to a circuit in which ammonia is circulated, with a pump (8) passing the ammonia through a heat exchanger (3) after the turbine. Between the pump and compressor is an evaporator (4). This is in parallel with a valve (9). Parallel to the flow from the comparator (4) to the compressor are two heat exchangers (6, 7) with a condenser (5) between. These heat exchangers are also connected to the turbine (1). Thus part of the evaporated ammonia gas is compressed then condensed while heat is extracted, expanded, then reunited with the main flow.

Patent DE-2731054-A1 (DE)
Title: Flaw detection system used for magnetic materials - involves Helmholtz coils to apply field and oscilloscope as indicator
Inventor: LAMBECK MARTIN PROF DR ING
IPC: G01N27/90
Filed: 1977-07-07
Abstract: A function generator generates an 80 Hz sine wave which feeds an amplifier (2). The current from the amplifier flows by way of a low-inductance resistor (3) into a pair of Helmholtz coils (4) and creates a field which magnetises a sheet specimen of magnetic material almost to saturation. A voltage induced in a probe coil (6) controls the vertical deflection of an oscilloscope, whilst the voltage across the resistor (3) controls its horizontal deflection. When the probe coil is in the vicinity of a geometrical fault in the material, the oscillogram exhibits a wide, little-structured scan pattern. However, at certain critical fields the oscillogram has a spiked characteristic which is dependent on the nature of the material.
Patent DE-2732273-A1 (DE)
Title: Bruising mill for grain - has baffle plates fitted underneath milling chamber cover at diametral positions
Inventor: HEGER ALOIS
IPC: B02C13/286
Filed: 1977-07-16
Abstract: The grain is fed into the mill via hopper (1) and reaches the milling chamber (3) via cover (9). The rotating cutter (4) mounted on a vertical shaft grinds up the grain and particles ground to the proper size are discharged by centrifugal force through grille (5). A set of baffle plates (10) fitted to the underside of cover (9) and place diametrally ensures that any grain not yet ground and thrown up by the rotating cutter (4) is repeatedly returned towards the cutter. By this arrangement the baffle plates are not part of the grille assembly and need not be replaced together with the grille exposed to wear. The design achieves a baffle plate layout independent from the grille assembly, so that a grille replacement which may become necessary does not involve taking down the baffle plates as well.

Title: Oscillator frequency control circuit - uses error sign signal, frame frequency and auxiliary reference pulses to reduce mean phase deviation
Inventor: SETTFORS JAN DIPL ING
IPC: H03K5/26
Filed: 1978-06-23
Abstract: The frequency-control circuit has a phase discriminator comparing a reference frequency with the oscillator's frequency, which is an integral multiple of the reference. The discriminator's output passes to a counter coupled to the circuit that varies the oscillator's frequency. A frame frequency is derived fromt he oscillator's output by dividing by a denominator equal to or greater than the quotient of the oscillator's frequency change without control over a given parameter interval and the generator frequency change per control step. An auxiliary reference frequency is derived from the reference frequency and is equal to or an integral multiple less than the frame frequency. The frame frequency, the auxiliary reference pulses and a direction signal are combined to suppress frequency control when given conditions occur.
