Title: Sleeve nuts mfr. system - forms bore of collar and thread in sleeve in press
Inventor: RAUSCH ULRICH
IPC: B21K1/70
Filed: 1978-12-01
Abstract: The sleeve nuts as used e.g. in pipe couplings are made from preformed parts, which are in the shape of a non-cylindrical sleeve (13) and a flange (14). The bore in the flange is reduced by pressing the flange between two dies (11, 22). The edges on the bore of the flange are shaped by rims (19, 25) on the die. The die at the same time enlarges the bore of the sleeve section to the pitch diameter of the screw thread. The screw thread is formed in the next press operation.

Title: Measurement sensor, esp. torque indicator, with temp. compensation - involves addition of measurement bridge output with differential temp. dependent signals
Inventor: WERNER FRITZ DR
IPC: G01L1/22
Filed: 1978-12-27
Abstract: A measurement sensor temp. compensation device is partic. for torque indicators using strain gauges mounted on deforming bodies or capacitive or inductive deformation sensors involving use of two or more temp. sensitive electrical elements. It is a simple, relatively reliable device, minimising the influence of thermal expansion and resulting measurement system null point errors. The temp. sensitive electrical element output signals are fed to a differencer via amplifiers. The difference signal is added to a measurement bridge output, also via an amplifier, in an adding circuit. The temp. sensitive elements may be connected together to produce a direct difference signal which is fed to the adder via a single amplifier. Alternatively, they may be connected individually to parallel adders with inputs from separate bridges.

Title: Automatic positioning of pouring spout - by permanent magnets on travelling tables and proximity sensors on casting device
Inventor: HUEBSCH FRANK DIPL PHYS
IPC: B22D37/00
Filed: 1979-05-11
Abstract: The automatic positioning of a casting device relative to the gates of moulds on travelling tables is achieved by proximity sensors which pass their signals to the fine adjustment drive of the casting device carriage. They operate in conjunction with permanent magnets on the travelling tables and a coil on the casting device. This achieves an exact alignment of the pouring spout of the casting device with the gate of each mould. If a higher capacity is demanded, this alignment can be maintained even during the cyclic motion of the travelling tables.

Title: Twin-belt drawing unit - has a fixed guide for one belt and a moving adjustable guide for the other belt
Inventor: SCHLYKOV GENNADY NIKOLAEVITSCH
IPC: D01H5/26
Filed: 1979-07-13
Abstract: The angle of the movable belt guide allows a stepless adjustment of the size of the gap between the continuous belts at the outlet for the fibre material being drawn out of the feed rollers. This gives a lateral and longitudinal stepless adjustment, in relation to the movement of the fibre material, in their vertical planes. The system ensures that the whole of the fibre material can be given a controlled processing at the outlet, and also that there is the best possible distribution of the friction force fields in the fibre material being treated.

Title: Insulated electrical boiling plate - having resistance coil in groove with aluminium foil beneath over high temp. thermal insulation
Inventor: FISCHER KARL
IPC: H05B3/70
Filed: 1979-08-17
Abstract: Electrical heating plate has a cast metal body with a spiral groove contg. electrical resistance element inside a ceramic insulation. The underside of the plate has a metal cover over it. This cover contains a layer of heat resistant or refractory insulation. This is covered by a layer of bright crinkled Al foil which helps to reflect heat upwards back onto the plate. Some water adsorbent material is placed above the foil such as silica gel. This serves to adsorb any water and is regenerated by the heat from the hot plate. The hot plate is for incorporation into cooking stoves. The insulation protects the stove structure below from thermal damage esp. when it is constructed from heat sensitive material.

Title: Detector and checking system for mark pattern - determines marking by counting bright and dark fields using electromagnetic scanning
Inventor: KLUGE BERNHARD
IPC: G06M11/02
Filed: 1979-12-10
Abstract: The system is intended for at least two-dimensional members, in order to determine the number of pattern forming apertures, stamoings, markinqs, raised parts etc. on assembly parts, plates, sheet metal pieces, print plates etc. The total number of markings is determined by counting bright-dark field results allocated to each marking. For this purpose the checked workpiece is scanned by electromagnetic radiation in a linear manner. Displacement occurs between the checked workpiece and the scanning arrangement. Each state of a line is detected per a time unit and evaluated with respect to the selective response of the electromagnetic radiation in a receiver. The latter is preferably formed by a set of adjacent photodiodes which interpret subsequent, time related states as belonging to a single marking. The correct number of markings may be obtained by an electronic evaluation circuit, using a master template.

Title: Drive control for microfilm reader - has separate reel drives for fast wind and braking and third drive for slow scan
Inventor: SCHULZE EWALD ING GRAD
IPC: G03B21/11
Filed: 1980-02-27
Abstract: A drive control for a microfilm reader has separate motors on the two reels, for wind control in either direction, at fast speed, and with a third motor to provide a controlled slow scan speed. The film is braked rapidly by stopping the takeup motor and by reversing the supply reel motor at a limited torque. In this position the third drive inches the film at a controlled rate. The combined effect of the two main drive motors provides a rapid wind and a rapid brake, without any film jerking. The third drive motor is brought into contact with the film by a solenoid and acts against a pressure roller. The reader indexes the film rapidly and then allows a maximum control for the search. The motors are controlled by an electronic circuit.
