Title: Error correction at data feeder and data control - has method of correcting errors by feeder switching and double readout of the feeder contents
IPC: G11C29/00
Filed: 1973-10-11
Abstract: The method of error correction by data feeder switching is one where a great number of similar data feed elements are collected so that word are fed with a given bit number and by virtue of the method of their build up a number of them cannot be used. For each word additional elements are alloted whose number corresponds to the feeder elements which cannot be used. These feeder elements are so arranged that during readout they give signals to identify themselves and give command to move to the next useful feeder element. During readout of feeder contents each word is read twice in quick succession and elements which inspite of the wipe out action of the first readout still contain the "L" value are classified are erroneous.

Title: Electronic protection of overvoltage shunt circuit elements - detects rate of impulses in shunt and switches network off if threshold is exceeded
Inventor: MATEJKA JAROSLAV DIPL ING
IPC: H02H6/00
Filed: 1974-07-31
Abstract: A logic network is used for protecting overvoltage shunt circuit elements against overheating, and thus for protecting the entire network concerned. Basically, the logic network determines the rate of use of the overvoltage shunt, and if this exceeds some given threshold, then the whole system is switched off. This is achieved by means of an up-down counter (Z) which is driven in a downwards direction by a clock (G) and in an upwards direction by impulses received from the overvoltage shunt. The contents of the counter are not allowed to fall below zero. A comparator element detects when the counter contains a particular number, corresponding to the threshold and if this happens a signal is produced to switch off the entire system.

Title: Elastic shock absorber for compressive loads - has axial holes to reduce shear stress due to radial deformation
Inventor: HALENE CLEMENS DIPL ING
IPC: F16F1/377
Filed: 1974-09-27
Abstract: An elastic shock absorbing element consists of two parallel circular steel plates (2, 3) between which an elastic rubber disc (1) is bonded. When the two steel plates are axially compressed, the rubber disc (1) in between is deformed such that it deflects radially. This deformation produces shear stress along the bonding layer which tends to separate the metal plates from the rubber. To reduce this shear stress, a number of axial blind holes (4, 5) in metal plates and rubber, ease the deformation of the compressed rubber (1). The element can be fastened end-to-end in a series to produce a complete writ with the required characteristics of deformation.
