Title: Electrical speed indicator for motor vehicle - uses optical display with scale sector increases to 225 degrees esp. for high speed vehicles
Inventor: KOWOLL HUBERT
IPC: G01P1/08
Filed: 1978-10-02
Abstract: The electrical device is for indicating the speed of a vehicle on its instrument panel and is designed to give more legible indication, esp. for vehicles with high top speeds for which conventional scale indicators may appear cramped. For a device containing a voltmeter with a transparent cover and scale driven by a d.c. source coupled to the engine speedometer shaft the scale is changed from a 115 degree to a 225 degree horse-shoe shaped sector. The voltmeter need not be directly connected to the speedometer but may have an intermediate speedometer shaft of any length. The indication device may alternatively consist of a straight line arrangement of LEDs with associated legends, or a group of three adjacent seven segment displays driven electronically.

Title: Evaluation circuit for varying-amplitude, pulsed electrical signals - contains regulating-circuit maintaining constant signal amplitude serving as reference for comparator triggering at set level
Inventor: JEENICKE EDMUND
IPC: G01P3/46
Filed: 1978-10-09
Abstract: An evaluation circuit for pulsed signals produced by an inductive leakage field generator e.g. for measurement of combustion engine crankshaft revolution rate, whose amplitude can vary between 0 and 100 volts, contains a circuit regulating the amplitude to a predefined value. The generator signal (E1) drives the non-inverting input of an operational amplifier (IC1) via a diode (D1) and parallel resistor (R1). The amplifier inverting input is connected to a fixed reference voltage defining the signal amplitude and determined by a potential divider resistor pair (R2, R3) connected across the supply raisl (P, M). The amplifier drives a transistor (T1) forming a variable impedance (RT) via a timer circuit (R5, C1). The variable impedance (RT) and the input resistor (R1) form a generator voltage divider driving a comparator (IC2) inverting input. The comparator output is fed to its non-inverting input via a voltage divider (R8, R9). It triggers at a fixed threshold level.

Title: Metal deposition by spark ignition - adjusting spark voltage and current to compensate for wear of rollers without stopping them
Inventor: TRISCHEVSKIJ IGOR STEFANOVITSC
IPC: B23K11/00
Filed: 1979-03-15
Abstract: The coating system has an electrode opposite the roller's working surface and connected to one pole of a voltage source to produce sparks. The metal coating is applied to the roller whilst the roller is in use. The current and voltage employed are chosen such that the metal deposited counteracts the metal worn away. The metal coating therefore has a constant thickness. The rate of wear of metal from the roller's surface is measured over a given time and the current and voltage set accordingly. The voltage source's second pole is connected to the roller via a sliding contact touching the roller at an appropriate place.

Title: Nuclear reactor absorber rod - contains absorber cylinder inside cylinder telescopically movable in outer cylinder
Inventor: ELTER CLAUS DR ING
IPC: G21C7/11
Filed: 1979-06-27
Abstract: A gas-cooled high temp. reactor is equipped with absorber rods, each of which consists of at least two telescopic cylinders. The outer cylinder is either stationary or movable. The inner cylinder which is movable relative to the outer cylinder carries on its inside the absorber material. Both cylinders are open at both ends so that a coolant can flow through them.

Title: Wave digital filter - has number of connection lines between arithmetic unit and external circuitry minimised
Inventor: SIMON KARL DR ING
IPC: H03H17/02
Filed: 1979-11-26
Abstract: The digital filter comprises a no-delay multi-port (arithmetic unit) with a number of delay circuits (external circuitry) connected in via inputs and outputs depending on the order of the filter. The arithmetic unit is designed for distributed arithmetic operations. The structure of the filter is chosen such that the number of connection lines (inputs and outputs of arithmetic unit) between the arithmetic unit and the external circuitry is minimised. This results in the filter occupying a smaller area when realised as an integrated circuit. The number of connection lines is half the number of delay circuits.

Title: Geometrical projections from filter cloth support - has grooved tops to aid filtrate discharge(CS 30.5.80)
Inventor: KUPF LUBOMIR
IPC: B01D25/21
Filed: 1979-12-21
Abstract: The filter cloths or papers in a slurry filter rest on a solid support with a regular pattern of lines of geometrically shaped projections with channels between the projections for filtrate to run away. The tops of the projections on which the cloth or paper rests and which may be cylindrical, prismatic or frusto- conical, are flat or slightly curved. To provide extra filtering effect these tops are given grooves for aiding filtrate flow. The grooves in each surface may be a single parallel set or two intersecting sets. The grooves restore the filter rate redn. caused by close contact with the surfaces, esp. by thin, hard and compact cloths which have been calendered.

Title: Anti-jack-knife assembly for trailer - has turntable and transmission with linkage to linearly move towing point with steering angle
Inventor: RANCKE PETER-RUDOLF
IPC: B60D3/00
Filed: 1980-11-03
Abstract: The arrangement is intended for a trailer which is towed via an axially slidable towing bar and a rotatable turntable assembly. The towing bar is swivelably connected to one end of a tow rod whose other end is pivoted to a lever swivelable relative to the turntable assembly. This lever is swivelled due to the steering action by a chain wheel or pulley coupled to a larger wheel which is fixed to the frame to give a certain transmission ratio. The arrangement is such that the steering action rotates the wheel to produce a linear movement of the tow bar action point and prevents jack-knife motion between trailer and towing vehicle.

Title: Control device for additional motor vehicle brake lights
Inventor: NAPIERSKI REINHARD
IPC: B60Q1/44
Filed: 1981-01-26
Abstract: Control device for additional motor vehicle brake lights is to help to avoid unnecessarily stressing other road users who are normally dazzled and confused by additional brake lights which are mounted at a high position. With the new device, an element which controls the switching on and/or the intensity of the brake light can be influenced by an inert mass which is subject to the deceleration forces of the braking process. In this way, the signalling effect can be automatically matched to the respective travel state.
