Patent DE-2926984-A1 (DE)
Title: Controlling surface quality of continuously cast billets and slabs - includes measuring friction between mould and billet surface, used e.g. in casing steel
Inventor: MAIRY BERNARD
IPC: B22D11/16
Filed: 1979-07-04
Abstract: Method comprises comparing a measured signal (Qa), representing the friction between the mould and the billet, with a predetermined reference signal (Qref). The comparison is used to determine surface quality. Signal (Qa) pref. represents the movements, and esp. the accelerations, of the mould. The recording, processing, and comparison of the signals, together with subsequent repair operations, are pref. treated partly or totally via automatic processes. Conditions which create surface defects on the cast billet are immediately detected, and can be corrected.

Title: Solderless connection box for flat multiple core cables - has input and output cutting strips connected by integral conductive tracks
Inventor: FASTL ALFRED
IPC: H01R4/24
Filed: 1979-08-14
Abstract: The connection box uses a base (2) carrying sets of metal strips (3) which cut through the insulation of the cables to make contact with their cores, forming solderless connections. The metal strips are mounted so as to form connection with conductive paths (5) formed on the surface of the base. These can be soldered tracks, printed on the surface. At one end, the base can carry two sets of strips for two cables, and a single strip cable is mounted at the other end. The cable can be forced down onto the strips by a cover (6) which has toothed edges (9) to form the connections, and which is locked by a screw (7). This cover has a protective layer to prevent oxidation.

Title: Measurement and direct indication of mechanical power - is by potentiometer multiplication of rotation speed signal and torque
Inventor: LENNARTZ ALOIS PROF DIPL ING
IPC: G01L3/24
Filed: 1979-10-09
Abstract: The device enables the formation and indication of a measurement value for the mechanical power of a rotating machine and derives the power value from measured rotation speed and torque using a simple computation circuit producing their product. Manual calculatory and the associated errors are eliminated and ease of monitoring is increased compared to conventional arrangements. The output voltage of a transducer (G) measuring rotation speed (n) is fed to a high linearity potentiometer (P) whose slider(s) is positioned by a torque (M) balance or similar. The voltage (US) at the potentiometer slider is proportional to mechanical power (P mech). Thus voltage is displayed on a moving coil voltmeter or other voltage instrument. It may be fed to a data processing system for further processing or use in process control.

Title: Rotating cable drum assembly - has cylinder for tensioning wind-up spring as cable is withdrawn and is provided with locking ratchet
Inventor: MENSCHING HELMUT
IPC: B65H75/44
Filed: 1980-01-16
Abstract: The cable drum has a device for automatically winding up its cable. When the cable is withdrawn from the drum, a cylinder rotates and places a spring under tension, or compression. The cylinder has a ratchet arrangement that prevents it rotating back again under the action of the spring. Releasing the ratchet causes the cylinder to rotate and wind up the cable. A second spring with a smoothly rising force curve acts against the first spring and is located between the spindle of the cylinder and the cylinder. The drum has a long life, uniform tension in the cable, an automatic locking ratchet, and maintenance free connections.
Patent DE-3003350-A1 (DE)
Inventor: PORTMANN HUBERT
IPC: G02F1/163
Filed: 1980-01-31
Abstract: An electrochromic display cell has several electrode segments 1 spaced from a common counter-electrode 3 by an electrolyte 2 and disposed to represent different symbols according to those segments on which a coloured or effaced state is conferred by application of a current in one direction or in the other between the segments and the counter-electrode. To achieve one of the current directions a bias voltage provided by a generator 16 is applied for a fixed time by a switching circuit T1, T2 to a field-effect transistor T6 which completes a circuit through the cell 4, electrode 3, electrolyte 2 and segment 1. The transistors 6 have channel widths proportional to the segment areas so that all segments receive the same charge per unit area. The segments whose state is to change in the other direction are short-circuited with the counter-electrode by transistors T7. The display is particularly useful for the display of time data on watches.

According to the parent patent a heating medium flows through the spaces between the granules. The amendment suggests a system of pipes, esp. in a meandering pattern, for the passage of the heating medium. The pores of the granules outside the pipes are filled with a gas such as carbon dioxide. If the heating medium is water, the amendment makes is suitable for use in food.
Patent DE-3006580-A1 (DE)
Title: Ring interferometer reflection and polarisation rotation suppression - using short source coherence time and input-output polarisers
Inventor: PETERMANN KLAUS DR ING
IPC: G01P3/36
Filed: 1980-02-22
Abstract: A ring interferometer using the Sagnac effect for absolute measurement of rotations or rotation speeds has simple provision for the suppression of the unwanted effects of reflections and polarisation rotation. The ring interferometer light source coherence time is selected as being smaller than the transition time of the light around the light path (L). In particular, the coherence time of the light source may be selected to be smaller than the difference in transition times of both natural wavelengths of the light path. The light from the source (Q) passes through a polariser (POL1) before being coupled into the light path. It is then passed through the same or another polariser (POL2) on being coupled out of the light path after its transition.

Title: Preselector for received signal introduced before mixer stage - uses switching system when preselector has been automatically tuned to desired frequency
Inventor: MANKOPF MICHAEL DR ING
IPC: H03J1/00
Filed: 1980-04-16
Abstract: The object of the circuit arrangement is to introduce rapidly set preselector tuning into a radio receiver. The aerial input (1) is applied to the first frequency mixer stage (4) through a selector switch (3). The aerial can be either directly connected to the mixer, or be routed via the preselector (2). The preselector setting is governed by a processor (5) responsive to the tuner (7) setting and the mixing oscillator (6) output. Initially, when a station is selected on the tuner the switching unit connects the aerial directly to the first stage mixer. When the preselector (2) has been set up and is operating it is switched into circuit to improve reception. The switching is normally done by time delay and is controlled by the processor.

Title: Steering drive for vehicles with chain steering - tensions steering chain using rollers fixed on spring loaded central guide piece
Inventor: RUST BERND-HENDRIK DIPL ING
IPC: F16H7/08
Filed: 1980-12-11
Abstract: The steering drive is for vehicles with chain driven steering consisting of a chain wheel (1) and a larger steering disc (2), driven by an endless chain (3). On the outside of both chain runs (4,5) are tensioning rollers (6,7) which rotate freely on levers (8,9) rigidly connected to a central guide piece (10). The guide piece (10) is spring loaded and slides on a guide rail (11) between the chains so that when one chain is tensioned during steering the guide piece cuts and clamps onto the guide rail thus maintaining the tension on the untensioned chain run. When the steering tension is removed the tensioner rollers return both chain runs to their original tension.
