Title: Filter cct. for sinusoidal AC voltages - selects continuous AC voltages by LC resonant cct tuned to nominal frequency
Inventor: USINGER WOLFGANG DR RER NAT
IPC: H03H11/12
Filed: 1973-10-10
Abstract: The resonant circuit is loosely coupled through a voltage divider consisting of two resistors. An amplitude corresponding to this voltage divider is collected from the resonant circuit and applied to an impedance transformer, to whose output diodes are connected. They are biased in forward direction through resistors by the supply voltage. They are decoupled for d.c. by a capacitor, and transmit to the impedance transformer output an input pulse appearing at the voltage divider, not corresponding to the resonance amplitude. The limiting system effects by passing of high spontaneous amplitudes as well as a long built up to the resonant frequency. By limiting non-synchronous, continuous amplitudes it selects a narrow band.

Abstract: Signal inputs and outputs are interconnected by several memory units on a common substratum material, which are formed by memory cells and assigned decoding circuits, on the substratum used to make the memory units. The interconnection is done on the basis of data on the position of manufacturing errors and is such that by error-correcting coding or by the use of auxiliary memories, in which the data on the position of the manufacturing errors is written invariably or variably, the memory can store data free of error, even though erroneous memory units are also used to build up the memory.
Patent DE-2362161-A1 (DE)
Title: Hot duct injection moulder for multiple small articles - has additional insulating annulus around heat conducting core
IPC: B29C45/27
Filed: 1973-12-14
Abstract: A hot duct injection moulding machine comprises a hot duct distributor plate clamped between a mould plate and a clamping plate; the distributor plate comprises a number of smooth-bore transverse passages, in each of which there is seated a core cylinder having a flange at the front of the distributor plate and a screwed-on nut at the back. Each core cylinder contains a screwed-in, heat-conducting core which itself contains the sprue duct and projects some way out of the heat distributor plate into the nozzle unit. There is thus an intermediate, annular space between the outer face of this heat-conducting core and the inner face of the nozzle unit, all as in the Parent Patent, in which it was intended that this annular space should be filled with partially set injected material which would thus constitute a thermal insulation. In this Parent of Addn, the heat-conducting core has a thermally insulating annular chamber in the vicinity of its cylindrical surface, esp. constituted of turned-in channels forming a setback from the cylindrical surface and themselves covered by a cylindrical sleeve. This provides the necessary additional insulating effect. When the penetration of the heat-conducting core into the nozzle unit is relatively long.

Title: Fail-safe three-channel clock generator - controls three shift registers using pulse generated by three square-wave generators
Inventor: LOTZ ALFRED
IPC: G06F11/18
Filed: 1973-12-22
Abstract: The input variables of the three shift registers are logic functions of the output variables according to the linkage of a 2 to 3 majority logic. The errors of the three output variables across the shift registers are stored in associated storage elements by means of a fail-safe error monitoring circuit according to logic functions of the 2 to 3 majority logic, taking into consideration the transmit time differentials by the delay elements. The warning lights indicate the errors. The error monitoring circuit consists of fail-safe components. The output signals of the rror monitoring circuit become zero in the event of an internal error.

Title: Blow moulding mandrel with annular air outlet(s) - to cause progressive detachment of the parison
Inventor: ROBERG PAUL DR ING
IPC: B29C49/58
Filed: 1974-03-16
Abstract: Mandrel for blow moulding tool has a rigid neck used to calibrate the bore of the parison and a core tube which can extend to open an annular outlet between bevelled mating faces between the end of the neck and the shoulder to the tube. The outlet axis is divergent from the mandrel axis. The conical air jet issuing from the inclined annular die promotes early and uniform sepn. of the inner surface of the parison from the surface of the mandrel, producing parisons of radially uniform wall thickness. The short contact land length ensures a low and reproducible degree of mandrel/parison parison friction regardless of the length of the mandrel generated.
Patent DE-2418924-A1 (DE)
Title: Logic network for stored data failure correction - uses decoders and voting system to correct failures in data stored in correction coded form
Inventor: ENZMANN WERNER DIPL ING
IPC: G06F11/18
Filed: 1974-04-19
Abstract: The binary information is held in a storage register, in the form of a redundant code which contains sufficient information to correct most errors. In the network described here, the word read from the store is fed to two decoding networks (as opposed to three in the original system). This is of value since the decoding networks cannot be implemented as single integrated circuit elements. The decoder outputs are fed to a number of voting networks which decide wheter or not a connection is required. The appropriate bit is then restored to each storage element in the word via a suitable transmission network.

Title: Continuous separation of component mixtures - using rotating annular vessel with cells filled with adsorbent material
IPC: B01D15/08
Filed: 1974-08-26
Abstract: Continuous separation of >=1 component from a mixt. so specified that the components, having primary velocities in one direction, have a second velocity component super-imposed on this, so that the two components are collected at two different positions. The device consists of a separation zone to accept the material, a feed section and suitable receptacles for the separated components. The relative posn. of the separation zone to the receptacles and the feed zone is changed so as to produce the required velocity component, this been variable with time. The primary velocity variation is produced by passing the mixture through a material with different affinities for the different components. The principle is capable of application to any mixt. of components where several are dissolved or suspended in a carrier fluid. It provides a continuous separation where often at present only batchwise operation is feasible.
