Title: Wire guide for mosaic printer - uses welded gemstone parts to provide high strength and chemical and thermal resistance
Inventor: RICHTER HERMANN DIPL ING
IPC: B41J2/255
Filed: 1978-02-22
Abstract: The two gemstone parts (1, 2) can be welded together by a thermo compression technique in which case a fine aluminium wire is employed laid along the side to be joined. The parts are then pressed together and heat applied to form the joints (5, 6). In this case a temp. of approx 630 deg.C is appropriate and a pressure of 1 to 1.5 kp/mm2 is used. In order to ensure that the gaps left for the printing wires are of suitable size, gauging wires (14, 15) are placed between the parts during the wlding process. The wires have a diameter somewhat greater than that of the printing wires and are made of the same gemstone material as the parts so as to exhibit the same thermal expansion during the welding.

Title: Controlling crystallisation of injected thermoplastic materials - by the application of different pressure sequences during cooling
Inventor: CHANG LONG FEI
IPC: B29C45/00
Filed: 1978-12-20
Abstract: A method for inhibiting or promoting crystallisation in freshly injected thermoplastic material such as polyethylene terephthalate, comprises in the first instance applying a first pressure (P1) during the initial phase of cooling, and then at a predetermined temp. above the Tg, applying a second pressure (P2) much greater than the first until the material has cooled below the Tg and in the second instance cooling the injected material first at a very high pressure (P1) and then as cooling progresses at a series of decreasing pressures (P2) much smaller than the first. By manipulating the pressures as above, in one case the formation of spherulites is inhibited, whilst in the second the formation is promoted. In the first instant (P1) may be 100 psi and (P2) 20,000 psi., and the predetermined temperature is 200-220 degrees C. In the second instance the first pressure is 20,000 psi and the pressure is reduced by about 300 psi for each degree of cooling after the spherulite growth rate has reached its maximum.

Patent DE-2944655-A1 (DE)
Title: Aligning carrier phase in data transmission - using nonlinear limiting member in digital filter loop
Inventor: GOECKLER HEINZ DIPL ING
IPC: H04L27/06
Filed: 1979-11-06
Abstract: Information for regulating the carrier phase is derived from the comparison between postulated and measured phase deviations. When the reception is mixed with background noise the regulator circuit is affected and may produce far too large a carrier phase correction. The digital loop filter contains an integrating branch consisting of a delay member and an accumulator. Multipliers permit each element to be weighted for optimal results. The proportionality branch comprises a limiter element by which large deviations due to background noise from a postulated value are no longer processed. This limiter does not diminish the regulator sensitivity to genuine carrier phase deviations.

Title: Hospital refuse disposal unit - sterilises random refuse in disposable containers with subsequent drying producing combustible mixture
Inventor: DRAUSCHKE ALFRED ING GRAD
IPC: A61L11/00
Filed: 1979-12-10
Abstract: All refuse is collected without sorting in disposable, but sturdy containers and sealed. The containers are kept in low temperature refrigerators until a sufficient volume has accumulated for bulk transportation in refrigerated trucks, which take the waste to a central disposal installation. The refuse-containing vessels are placed, without being opened, in a sterilizer, where they are subjected to a set steam pressure at a min. temp. of 134 degrees C. The drum-type sterilizer is designed to carry out at the same time a mechanical reduction of size of the entire charge with particular regard to items in the waste which are unaffected by the steam pressure and temperature. The result is a homogenous wet mixture which, after being dried up to 10% moisture content, presents an easily combustible material usable in heat producing equipment.
