Title: Stabilised power supply operation amplifier circuit - ensures symmetrical operation about null position
Inventor: REGER GOTTFRIED DIPL ING
IPC: G05F1/585
Filed: 1973-08-01
Abstract: Positive and negative input potential is applied to two regulating transistors controlled by two operational amplifiers operating as error detectors. Dependent upon the difference between the reference inputs from an input selector and the outputs, the operational amplifiers will control transistors in a proportional mode. Current limiters control a further pair of operational amplifiers the outputs of which are transmitted to the input reference selector. When overloading occurs these amplifiers generate an output to reduce the reference voltage. It is claimed that the symmetrical form of the circuit ensures totally symmetrical positive and negative output potential control over the range of operation.

Title: Pressing modulated magnetic storage discs - is by using matrices with residual magnetisation of high curie temperature
Inventor: SEEHAWER EBERHARD WILHELM
IPC: G11B5/86
Filed: 1973-08-24
Abstract: For pressing, in large production runs, of ready-modulated magnetic discs it is essential for the guidance grooves for the playing head to be exactly positioned relative to the magnetic recording. The manufacturing process entails the use of matrices with a residual magnetisation of high Curie temperature and a magnetic modulation which is a mirror image of the required copy. The press used has dies which can be heated and cooled and which presses the two matrices together after a thermoplastic mass, magnetic layers and labels have been placed between. The matrices have an inner groove zone the residual magnetisation zone being outside it. During pressing the Curie temperature of the magnetic layer is exceeded, the copy being ready when this subsequently cools below the Curie temperature.

Title: Spacer-rings for moulds of synthetic optical lenses - contg. polyisobutylene, sulpho-chlorinated polyethylene, ethylene-vinyl acetate copolymer and chalk
Inventor: FRICKE HELMUT
IPC: B29C45/00
Filed: 1973-09-13
Abstract: A spacer-ring for the 2 parts of a mould, esp. a glass mould, for making optical lenses from casting resin such as diethylene glycol bis-allyl carbonate, is formed from a compsn. contg. polyisobutylene, a sulpho-chlorinated polyethylene, an ethylene-vinyl acetate copolymer, and chalk as filler. The compsn. does not contain a plasticiser which cold diffuse into the lens matl. Exchange reactions do not occur between the compsn. of the ring and the casting resin. The elasticity of the ring is sufficient to prevent sepn. of the lens from the sections of the mould during moulding. The rings form a water-tight seal, so that polymsn. can be carried out in a water-bath. The lenses can easily be removed from the moulds. Spacer-rings of height 25 mm. and wall thickness only 2.5 mm. can be made by mass-prodn. methods. The rings are useful for the prodn. of lenses with a dioptric effect. After use, the spacer-ring cab be ground down, and the granulate can be cast again.

Title: Seamless metal tubes prodn. - is based on hot rolling and stretching of stressed tube blank followed by hot drawing
Inventor: UHLMANN OTTO
IPC: B23D79/12
Filed: 1973-10-15
Abstract: The seamless metal pipes are made by pressing or hot rolling a tubular blank from an ingot. This blank is reduced in size by subsequent cold rolling and/or drawing. The pipe is then drawn at a temperature below the recrystallisation temperature and the tube is subsequently drawn through a guide concentric to the bore. The drawing at low temperature ensures that the soft extruded pipe is work hardened, straightened and smoothened simultaneously. The pipe blank has a turned end which is pushed through the die system, and the drawing head engages the drawing end of the pipe. The internal mandrel is pushed into the pipe bore from opposite ends. The pipe is drawn to accurately round shape through the die with the assistance of the mandrel. A stripping or shaping tooling arrangement is arranged behind the die which makes the surface of the pipe smooth in order to ensure good concentricity of the outside diameter and the bore.

Title: Automatic clamping dental handpiece - has centrifugally movable pressure bolt acting on clamp sleeve to close on tool
Inventor: BJARSCH MAX
IPC: A61C1/14
Filed: 1973-10-26
Abstract: Dental handpiece has two or more spring wires or bands with flyweights, fitted at the lower part on a movable pressure bolt which acts on a clamp sleeve. The other ends are fitted to the upper part of the hollow shaft. Clamping and unclamping of the chuck for the tools occurs automatically. Centrifugal force on the rotating spring wires or bands shortens the distance between the upper and lowe fastenings and the pressure bolt is thus drawn upward. This movement closes the chuck as soon as the drive rotates the handpiece fast enough, so that a tool held in position is automatically gripped, and released when the drive is stopped.
