Patent DE-2526410-A1 (DE)
Title: Bus bar with address wires - each wire consecutively connects output terminal of socket to input terminal of another socket
Inventor: KAHL LUDWIG DIPL ING
IPC: H05K1/00
Filed: 1975-06-13
Abstract: The bus bar is designed for the control of the electronic assemblies that are plugged in. Each wire consecutively connects an output terminal of a plug-in socket to an input terminal of another socket. A specified sequence is prescribed for the address wires, so that address wires needed at an assembly form the beginning of this sequence. Other address wires are moved by connection inside the assembly to the beginning of the sequence, while retaining the required order. The advantage of this arrangement is that no address decoding is necessary, so that when faulty components are changed no coding errors can arise due to wrong programming.

Title: Crucibleless zone melting furnace - for semiconductor rods, esp. of silicon, with receptacle suspended from reference flange for rod drive mounting
Inventor: STUT HANS
IPC: C30B15/30
Filed: 1975-08-04
Abstract: The stationary has a heating arrangement for the prodn. of the molten zone and is fitted with a receptacle to serve as the zone melting chamber.

All positional changes induced by vacuum, excess pressure, thermal or mechanical stresses are kept away from the rod and its drives. This enables silicon crystals of >50 mm dia. and >1 m length to be pulled in a high quality and specified dopant content.

Title: Hydraulic percussion machine - has piston in two halves separted by elastic component with larger half as hammer
Inventor: POTOZKIJ WASILIJ B
IPC: E21B1/38
Filed: 1975-08-13
Abstract: Liquid travels through passages in the housing, which holds a stepped piston whose largest diameter portion bears elastically against the machine head. The piston reciprocates under the action of the liquid, striking an anvil fixed to the tool at the head end. On the piston is a stepped ring type differential valve performing the same reciprocating movement so as to deliver the liquid to atmosphere or to a chamber below the piston. The piston is divided into two halves, the larger one (3) acting as the hammer and the smaller one (4) purely as a piston, while an elastic component (5) fits between the halves.

Title: Flexible joint for plastics lined pipes - is pref. T-section thermoplastics strip with split web
Inventor: OSTERHAGEN GERHARD
IPC: F16L21/02
Filed: 1975-09-20
Abstract: Both of the longitudinal edges or arms of the strip where they lap the plastics lining of the components to be sealed, are firmly sealed to the plastics facing or lining. The central web of the seal penetrates into the joint and is firmly connected to the end face of one of the components. Where continuously surrounding components such as pipes or vessels are to be joined, an endless sealing band is used.

Title: Reinforcement of rails with band steel by soldering - for linear drive mechanisms, maintaining pressure during fusion of solder paste
Inventor: WEISS RUDOLF
IPC: B23K1/00
Filed: 1976-04-01
Abstract: Economic process for reinforcing rails with band steel by soldering, for use in linear drive mechanisms, is carried out by pressing the band steel uniformly against the rail during soldering, and maintaining this pressure during melting of the solder paste and the resulting thinning of the solder paste layer. The solder paste is applied either to the lower surface of the band steel or to the rail, and pressing of the band steel against the rail is maintained even when teh solder paste layer becomes thinner due to melting, so as to maintain high accuracy of dimensions of rail. The rail, including band steel and pressing means, is brought to soldering temp. by passing it through a continuous-type kiln or heating in a chamber kiln.

Title: Underwater sand delivery equipment - has valve controlling intermittent air supply from receiver and continuously running compressor
Inventor: SCHNELL LUDWIG OORENZ
IPC: B65G53/06
Filed: 1977-02-15
Abstract: The equipment delivers underwater sand and gravel by means of an intermittent compressed-air supply generating a vacuum at the conveyor head inlet. The air is supplied via a periodically-actuated control valve (5) from a receiver (1) connected to a compressor running continuously. The valve can be arranged to open for 2 seconds at a time. The design enables a larger quantity of air to be delivered to the inlet each time the valve is opened than would be the case if the supply were taken directly from the compressor, thus giving greater agitation of the spoil.
