Title: Miniature relay with moving armature - has strip or wire contacts clamped at two points of relay frame
Inventor: ZIELKE ALFRED
IPC: H01H50/54
Filed: 1978-12-05
Abstract: Miniature relays find application in fields requiring high insulation resistance, short-circuit strength, potential separation and switching of inductive loads. In the particular miniature relay, at least one contact is formed by a wire, or a strip (22,23), clamped on both sides in a frame surrounding at least a part of the relay components. Pref the wire or stri is of a compound material, in which a substance of salient strength and elasticity properties is embedded in a matrix of material with salient conductivity properties. Instead of embedding the materials, they may be layered on each other. Fibre material may be used for the substance of salient strength and elasticity properties. The contact wire or strip can be brought out of the frame, thus forming an electric terminal. If the frame is rectangular, the wire is clamped in two adjacent, or opposite sides. The wire m ay be bent and supported at a point coupled to the armature (205) or the housing.

Title: Phase locked loop control system gyroscope wheel speed control system - uses phase-locked loop having low response provided by frequency divider and low pass loop filter
Inventor: OLBRECHTS GUY R
IPC: G01C19/06
Filed: 1979-02-27
Abstract: The phase-locked loop includes a h.f. (e.g. 20 MHz) crystal controlled voltage controlled oscillator (VCXO); a divider (33b) for dividing the VCXO frequency down (e.g. by six decades); a phase comparator (35) for comparing the output of the divider with a low frequency reference signal. A loop filter (37) is provided for filtering the output of the phase comparator so as to give the loop its desired dynamic response characteristic and bandwidth. A summing amplifier (39) sums the output of the phase comparator with a modulation signal. The arrangement controls the frequency of the power applied to a gyroscope to rotate the seismic mass (wheel) of the gyro so as to compensate for movement of the gyro case about the spin axis of the gyro, the modulation signal having a voltage level linearly related to the rate of movement of the gyro case about its spin axis. This signal is obtained from a second gyro mounted so as to sense movement about the spin axis of the gyro whose power frequency is being modulated.

Title: Starting control for semiconductor inverter - detects excessive current flow and switches relevant transistor out of circuit predetermined interval
Inventor: RARISCH RINALDO ING GRAD
IPC: H02H9/00
Filed: 1979-10-08
Abstract: The starting control is for a semiconductor oscillator feeding a load such as an asynchronous motor, whose starting current is higher than its normal current. Each time a current limit, i.e. higher than the normal current consumed by the load, is reached, the semiconductor operating during a half-cycleof the output waveform is taken out of circuit, and is reconnected after a predetermined time has elapsed. The oscillator switches two transistors (1,2) alternately for each half-cycle of its output waveform. The currents passed by the collectors of the transistors are registered by a current sensor (6) and fed to a comparator (8), which detects any current above the predetermined limit. Under these circumstances, it triggers a monostable (9). This controls the drive stage feeding the transistor which is currently conducting, taking it out of circuit.

Title: Hot coiling plant for spiral springs - heated to ten degrees Celsius above austempering point and stress relieved shock wise, direct resistance heating
Inventor: TOTH GUSZTAV
IPC: C21D9/02
Filed: 1980-03-28
Abstract: The increase in size of the grains of workpieces heated to above the austempering point Ac3 for forming into springs, which occurs otherwise, is prevented. The workpieces are raised at the most to a temp. of Ac3+10 degrees C, and this heating is effected by direct, electrical resistance heating during a maximum of 150 s. The workpieces are then coiled and cooled. Pref. the heating is performed cyclically. The cooling is carried out according to tempering technology. After cooling off the workpieces are stress relieved by shockwise, direct, electrical resistance heating. Overcomes the problems of the increase in size of the austenite grains at the surface, which tends to take place whilst the interior of the metal is approaching the required temp. Oxidn. and decarbonising are also prevented and the improved surface structure improves considerably the characteristics of the springs and lengthens their lifetime, paraffin wax, an alkoxylated carboxylic acid or a cholesterol carboxylic acid ester. Typical flux components are halides of Zn, Sn or NH4 or hydrazine hydroxide. Suitable thermoplastic fluxes are rosin, or satd. (hydroxy)carboxylic acids.

Patent DE-3014513-A1 (DE)
Inventor: WEVELSIEP KLAUS DR
IPC: G06V30/10
Filed: 1980-04-16
Abstract: The invention relates to a method and apparatus for identifying objects (e.g. consumer products in a supermarket) appearing in random positions and orientations and for random times on an image window and having an identification on the surface facing the image window in the form of a data field having contrasting indicia in at least one data track. The data field is first scanned with a scanning raster until a product identification code is recognized denoting the position and orientation of the data track. The data track is then read with a closely-spaced reading raster and converted to a videosignal. The amplitude of the videosignal is coded into binary digits at discrete time points and the digits are stored in a memory matrix organized into columns and rows in such a manner that an image of the data track is stored in the memory. Mutually overlapping partial regions of the memory are then read out in a pre-arranged sequence and fed to a decoder capable of accepting and decoding the information in this form. In this way, the information is converted from a row-by-row sequence produced by the reading raster into a succession of digits corresponding to individual partial regions of the data track for the recognition of individual symbols appearing therein.
