Title: Large wedge cotters used in building industry - are spring loaded to give positive grip and have quick release action
IPC: F16B2/14
Filed: 1973-10-17
Abstract: The wedge has two components that are pivotted at one end and are inclined to each other at an angle determined by a sliding block located between them. The top edge of the sliding block has a number of angled serrations that mate with similar serrations on the upper wedge component. A compression coil spring operates between the pivot and the sliding block and operates to open out the wedge components to grip the sides of the aperture. To ensure that the wedge grips the aperture surface uniformly the pivot pin moves in an elongated slot. At the free end of the wedge a lip on the upper component locates in a slit in the lower wedge component. A sharp blow applied to the sliding block release pin permits the wedge to be removed.

Title: Drive for craft in water - has swivel surfaces driven by roller chain executing wave motions
Inventor: HELLWEG GUENTER DIPL-ING
IPC: B60F5/00
Filed: 1973-10-27
Abstract: The swivel surfaces are fastened to the vehicles, and moved by drive motors inside it. The swivel surface cross section constantly forms a developing sine curve, the zero points of which advance in the movement direction of the wave, at an increasing speed. The movement is caused by a kinematic roller chain, the phase displacement angles of which are dissimilar, e.g. the angles change according to a mathematical relationship. The chain has links of different length, and a cardan or flexible drive shaft, extending in its longitudinal direction. A change in direction of rotation of the shaft causes a different phase angle adjustment. The swivel surfaces have three supports, e.g. wheels, skids, etc. for an advance movement on a level surface.

Title: Simple control circuit for seven-segment TV-channel display - has segments shorted out by controlled transistor switches
Inventor: GREYER ECKHARDT
IPC: H03J1/04
Filed: 1974-10-22
Abstract: The control circuit, which is used for a seven-segment display, has the display segments coupled in series between the terminals of a constant current source. Those segments not required in the display of a number or symbol are shorted out by the collector-emitter paths of transistor switches. When used as a channel indicator for television receivers, the transistor switches are arranged so that only two of them need be controlled if all segments are to be included in the display. The advantage lies in low current consumption and the simple form of the control matrix. The seven segments are arranged in the usual figure-of-eight form.

Title: Combustion start sensor for diesel engines - has ignition shock sensors whose signal is compared with reference signal
Inventor: ZIGAN DETLEF DR ING
IPC: F02P17/00
Filed: 1975-03-26
Abstract: The arrangement for determination of the start of combustion in internal combustion, espec. in diesel engines with direct fuel injection. The start of combustion is monitored for ensuring correct combustion and the monitoring system is relatively simple. Only those cylinders which have produced unsatisfactory signals for the start of combustion in relation to the dead centre position signals are investigated further. Other injection pumps do not need attention and they are left as before. The cylinder head (2) of the engine (1) has an acceleration transducer (6) which senses the ignition shock and produces a corresponding signal. This signal is amplified and compared with the signal from the dead centre marker on the engine flywheel. Both signals are displayed and the ignition shift can be readily detected and corrected.
