Title: Lobe dwell time control for radar antennae - calculates estimate of interference signals as input to sequential detector
Inventor: WIRTH WULF-DIETER DR ING
IPC: G01S7/36
Filed: 1978-05-22
Abstract: The antenna control system uses a summation circuit (S) in which the received signal for each lobe is summed over a certain time slot selected by a switch (C). The signal is multipled (M) to provide an estimated value of interference and noise signals. The received signals (x) are divided by the estimated value (D1) and fed to a sequential detector (SD). A special signal (ao) is divided by the estimated value and fed to the detector. The two thresholds (A, B) derived from the false signal and non-detection probability determine the response of the detector. Estimation of the rms value of the interference signal is effected during a time period following positioning of the lobe is one direction and prior to the emission of the transmit pulse in this direction.
Patent DE-2825928-A1 (DE)
Title: Rectangular-wave generator with pulse counter - used to define start and end of second wave phase shifted w.r.t. first wave
Inventor: FAULHABER REIMAR DIPL PHYS DR
IPC: H03K5/135
Filed: 1978-06-14
Abstract: The rectangular wave generator produces a second wave shifted in phase w.r.t. a first. A counter is started when the leading or trailing edges of the first wave appear. The counter counts a given number of pulses from an oscillator. At the end of its count the counter produces outputs that act as front and end markers for the phase-shifted second wave. The first wave is derived from the oxillator's output. The oscillator is a h.f. crystal oscillator. Alternatively, the first wave can be obtained from another source which is coupled to the oscillator.

Title: Double-acting ram hydraulic control valve - has pump pressure forcing control slide open against spring action
Inventor: MARTIN GEORG
IPC: F15B13/02
Filed: 1979-02-10
Abstract: The hydraulic control valve is for hydraulic rams used on harvesting machines, having a control slide and two solenoid-operated pilot valves. It has a union for connection to subsequent valves, and others for a continuously-running pump and a tank. When the valve is not actuated, pressure from the pump forces the slide back against spring action, freeing the union to the subsequent valves. Actuation of one pilot valve connects a passage to that containing oil under pressure, this passage being connected to the opposite side of the slide from the union and also to one side of the ram. The slide is first moved by the spring and then due to its taper end and alteration in pressure ratios between opposite ends is pressured by oil pressure hard against a seat, whose dia. is smaller than the mean dia. of the slide, shutting off the union.
Patent DE-2906197-A1 (DE)
Title: Cable core for carrying large electric currents - where conductor is coated with two layers of plastic insulation, the outer layer contg. both pigment and filler
Inventor: PUETZ DIETER DR ING
IPC: H01B7/36
Filed: 1979-02-17
Abstract: The conductor (1) possesses outer insulation of cross-linked polythene, consisting of two layers (2, 3). The inner layer (2) consists of polythene which contains neither pigments nor fillers; whereas the outher layer (3) consists of polythene contg. a pigment providing identification by colour, and also a filler improving external adhesion. In the pref. cable, only layer (2) is cross-linked; and layer (3) pref. has a thickness which is 1/10th to 1/3rd of the thickness of layer (2) when the total thickness (2+3) is min. 10-50, esp. 25-35% fine alkaline earth carbonate, e.g. finely milled chalk, plus a pigment. Cross-linked polythene has excellent insulating properties, but is very difficult to bond to fittings which are made e.g. of casting resin. The invention solves this problem by using a filler in layer (3) to assist bonding.

Plastic resists attack by acids and other corrosive agencies.
Patent DE-2916519-A1 (DE)
Title: Ultrasonic measurement testing device with noise signal elimination - checks value of each new measurement with continuously updated required value
Inventor: PRAUSE REINHARD ING GRAD
IPC: G01N29/11
Filed: 1979-04-24
Abstract: The device, for verifying the geometric measurements of tubes, rods or blocks, has each new measured value (M) compared with a required value. The measured value (M) is identified as a noise signal when the sum or difference of the measured value (M) and the required value (S) lies outside a given measuring range. Each verified measured value (M) is simultaneously used to update the required value (S) used for the comparison. This updating may be effected by obtaining the arithmetic mean value of the old required value (S) and the verified measured value (M).
Patent DE-2919158-A1 (DE)
Title: Contactless object identification using electro-decoded cards - has metal strip lengths tuned to alternating field component frequencies
Inventor: BLAESS BERTHOLD DIPL ING
IPC: G01S13/75
Filed: 1979-05-11
Abstract: The device is for identifying objects and has a transmitter producing an alternating electromagnetic field, a receiver for the field, and identification cards for attachment on the objects having metal strips affecting the field when placed in it. The cards are small and light and the identification takes place without contact between card and reader. The transmitter (SE1) produces a field made up of several frequencies. Each card has metal strips of different lengths tuned to different field frequencies. The receiver (EM1) determines which field frequencies are affected by the insertion of a partic. card and forms an object identity code from these frequencies. The effective lengths of the metal strips can be varied by length variations of permanent magnetic layers partially covering them.

Title: Transportable filter for radioactive element cooling pool - is temporarily connected to filter circuit and is moved for regeneration
Inventor: KUMPF HERMANN DIPL ING
IPC: G21C19/07
Filed: 1979-11-14
Abstract: A nuclear plant comprises an indoor cooling pool for radioactive components, the water being circulated through a filter by a pump. The filter unit is housed in a transportable casing, which can be suspended from the edge of the pool so that it is immersed, water from the pool circulating through openings in the casing. The circulating pump may either be connected by a quick- release coupling to the casing, so that it is disconnected simultaneously with the casing mounting components, or it may be permanently attached to the casing and transportable with it. The casing pref.contains several chambers arranged in parallel flow. As the filter is not a stationary plant component, it can be factory-made and installed later in the cooling pool, where the pool water provides shielding. It can also be travelled underwater to a regeneration location for the filter material.

Title: Helical rotor type vacuum pump - has packed type seals on rotor shafts with liquid cooling
Inventor: FRINGS HEINZ
IPC: F04C18/12
Filed: 1980-02-27
Abstract: The pump has two meshing rotors (4) within a casing (6). The rotor shafts (2) extend through side walls (11,12) into oil filled side chambers (15,16) which house the gears (18).

Title: Jack and path cord connector assembly - provides patch field and monitoring connections using appropriate interconnections between PCB and contact springs
IPC: H01R24/58
Filed: 1980-06-14
Abstract: The socket jack comprises a printed circuit board or card and circuit- making contact springs. The contact springs contact and coact with printed circuit conductors or elements on the printed circuit board to establish mutually insulated normal through circuits or current conducting paths each terminating at opposite ends in two terminals. The terminals of the normal through circuits are adapted to be connected to electrical equip. or electrical circuits located outside the jack. The contact springs are actuable by reception of a patch cord plug in the jack to open or break the normal through circuits so disconnecting the terminals of the normal through circuits from the second terminals. The normal through circuits may terminate at opposite ends in a pair of multi-terminal connectors. These multi-terminal connectors may be mounted directly on the printed circuit board. The invention may be used for interconnecting circuits of computers on data communication equip. like modems.
