Title: Chitin derivs with water clearing viscosityincrcg propertie - increasing properties
IPC: C02F1/52
Filed: 1970-07-23
Abstract: Crustacean shells can be converted to useful substances by partially de-aminating and partially deacetylating chitin.

Title: Cavitation free membrane pump - operated by an oscillating displacement piston
Inventor: MUELLER ADOLF DIPL-ING
IPC: F04B43/067
Filed: 1973-07-03
Abstract: Pump membrane separates a hydraulic and a conveyor space. There is an oscillating displacement piston to displace the hydraulic medium out of the hydraulic space which activates the membrane oscillations. A storage container for the hydraulic medium which can be connected to the hydraulic space through a snifter valve also has a further valve capable of separating the hydraulic space from the snifter chamber. The additional valve can only be activated by a force independent of the pressure present inside the snifter chamber through the membrane. The independent force can be fixed by a spring.

Title: Shadow-mask CRT fluorescent layer - has mask heated before each electron beam irradiation during manufacture of the layer
Inventor: STEPHAN KARL-GUENTER
IPC: H01J9/227
Filed: 1973-08-31
Abstract: The fluorescent layer for colour cathode ray tubes with shadow masks, has an electron beam irradiation process involved in its manufacture. The primary colour elements of the layer are each irradiated in turn through the shadow mask by the electron beam. Before each irradiation the mask and its relatively massive frame are heated to a given temperature so that the heating effects of the beam do not cause distortion or misalignment of the mask. This pre-heating prevents the mask 'doming' owing to the length of time between the first and last irradiation process and the different rates at which the mask and its frame reach a given temperature.

Title: Time division multiplex exchange - has a circuit for retransmission of PCM signals over outgoing lines
Inventor: LUTZ KARL-ANTON DIPL ING
IPC: H04Q11/04
Filed: 1973-09-28
Abstract: PCM signals are coming in over a line section consisting of one incoming and a corresponding outgoing line, and are retransmitted over outgoing PCM lines. Coinciding pulse frames are allocated to the incoming lines and corresponding outgoing lines belonging to the respective line section. Intermediate stores are provided for each incoming line, each allocated to a different group of time slots within the respective pulse frame. They can store the maximum number of PCM signals appearing in the respective group of time slots. Circuits monitor the appearance of PCM signals in individual groups of time slots on all incoming lines and deliver corresponding reports to a control device which determines intermediate stores which hold no signals, and those which hold signals due to be transmitted over corresponding outgoing line in the time slots belonging to the incoming line on which it was found that no signals over an outgoing line in time slots corresponding to the line on which the signals have just arrived.
Patent DE-2349486-A1 (DE)
Title: Locking mechanism for car seat hinge - having set play between hinges on opposite sides to allow both locks to operate
IPC: A47C1/025
Filed: 1973-10-02
Abstract: The seat hinges on both sides of the seat have interlocking gear segments which are attached to their respective seat parts. One segment is radially withdrawn from mesh to allow the seat back to be adjusted. Both hinges are joined by a cross bar to operate together from a manual lever on one side of the seat. In order to ensure that both hinge locks are meshed properly the cross bar is fitted to one hinge with a set amount of play. The amount of play is equal to moving the segment by one tooth in either direction and thus prevents the teeth from baulking with their tips touching. The design provides a simple solution to mass production tolerances in the two hinges and ensures that both are securely locked.

Title: Height compensating element for manhole covers - consists of two metal rings and jacking bolts for adjusting level of cover
Inventor: BERGWEILER KARL
IPC: E02D29/14
Filed: 1973-10-10
Abstract: The height compensating elements are mainly additional components used in conjunction with standard frames and manhole covers. The standard cast iron or steel frame is held on a metal ring which in turn sits on another metal ring. The top ring has a projecting rib which fits into the groove in the plate below. The upper ring has also three or preferably more raised jacking positions. A housing for protecting a jacking screw is screwed into a jacking position. The jacking screw is covered at the top against entry of dirt and the gap between the housing and the jacking bolt is filled with grease. The point of the bolt lifts the top ring and hence also the standard frame of the manhole cover into the required position. The whole frame can be lifted and tilted by means of these adjusting jacking bolts into the required position.
