Title: Wire wrap plug connector prodn. - uses application of curable thin blocking layer on plug connector after insertion of contacts
Inventor: VETTER KARL-HEINZ
IPC: H01R13/405
Filed: 1976-06-30
Abstract: The individual plug connector contacts are connected to the pins protruding from the plug connector, to enable a wire-wrap connection. The contacts are in one region embedded in a cast element. After insertion of the contacts in the contact insert of the plug connector, the insert is coated with a thin curable layer from the pin side. Silicone-based material is used for this purpose. After this layer application the connects are embedded in a thick layer of a resinous material such as epoxide resin.

Title: Detection of superficial fissures on motor vehicle parts - employs automatic optical system to examine parts in scanning mode (SW 27.2.78)
Inventor: DEUTSCH VOLKER DR ING
IPC: G01N21/89
Filed: 1976-08-04
Abstract: Non destructive testing of motor vehicle parts is performed to detect superficial fissures. Optical indications which avoid phantom faults are obtained automatically by using photosensitive devices to sweep the surface in lines. The optical detection system comprises a single beam camera with an amplifier which provides deflection of the beam to explore the surface under inspection line by line. Sweep rate is determined by a line frequency generator and a sync. pulse generator ensures synchronisation for an image tube. Horizontal and vertical deviation signals are provided by a generator. A logic comparator operates in conjunction with memory circuits to control the image and determine presence or absence of fissures.

Title: Underground coal seam energy extraction system - uses inductive heating with various arrangements for windings of underground coil
Inventor: FISHER SYDNEY T
IPC: E21C37/18
Filed: 1976-08-13
Abstract: The energy extraction system for underground coal seams uses an inductive coil to heat a given zone, fed from an a.c. source, connected to a frequency converter and a wave shaper in turn connected to the primary coil of a transformer. The secondary, which is connected to the underground coil, includes a variable capacitor in series with one connection. The heat generated enables the selected zone to be heated to a given temperature for a period of time which enables liquid hydrocarbon and other products to be extracted. The coils can be in helical or toroidal form. The turns of the coils can be made up of elements which approximate to a helix or a toroid, or a quasi toroidal shaped may be formed. The ratio of the outside to the inside radius is between 2:1 and 10:1, preferably 5:1.

Title: High speed multistage cabling machine rotor bearings - have elastomeric bush sleeve and special cooling air system
Inventor: FRANZ GUENTER DIPL ING
IPC: F16C27/06
Filed: 1976-11-26
Abstract: The arrangement of the bearings of the rotors in a multi-stage high speed cabling machine, in which the separate rotors are assembled in a common housing side by side or one above the other, and are separately driven, has, between the outer ring of the roller bearing on the journal of the rotor, and the seat of the bearing housing, a bearing bush consisting of three sleeves one inside the other. The middle sleeve of the three is a relatively thin-walled tube of an elastic material, e.g. 'Syspur' (RTM), and to prevent any build up of heat in the roller bearing due to the lack of metallic contact, between bearing housing and housing cover an annular cavity is provided to form a zone through which air circulates with a whirling motion. Reduces the noise and vibration levels to within reasonable limits and combines a satisfactory dispersal of heat generated in the bearings with their efficient lubrication.
Patent DE-2701550-A1 (DE)
Title: Audible engine speed indicator - feeds loudspeaker with beat frequency AC produced from engine speed dependent frequency and reference frequency
Inventor: FICK FRANZ DIPL ING
IPC: G01P3/48
Filed: 1977-01-15
Abstract: An arrangement is used for providing an audible indication of the engine speed of a vehicle. It is based on a device (3) which generates a direct or alternating current dependent on the engine speed. The current is fed to a mixer circuit (2) which is also fed from a signal source (1) to generate a beat frequency. The beat frequency is fed to an amplifier (5) and a loudspeaker (6) to give an audible indication. A low pass filter (4) with a suitably selected turnover frequency may be coupled between the mixer circuit and the transducer to remove the sum and direct components of the mixer output. In order to prevent the output frequency of the speed dependent signal generator (3) passing directly to the output transducer, a high pass filter having a turnover frequency higher than that of the low pass filter may be connected between the generator and the mixer.

IPC: C07D305/14
Filed: 1977-02-07
Abstract: Novel prostaglandin analogues of the formulae <IMAGE>  and <IMAGE> in which the substituents are defined in the claims, are prepared. The compounds of the formula CLXXXII are prepared by eliminating hydrogen halide from corresponding 14-halo-PGF-type compounds in order to introduce a 13,14--C IDENTICAL C- bond. The compounds of the formula CLXXXII A are obtained from the compounds of the formula CLXXXII by oxidising the 9-hydroxyl group to the keto group. The compounds which are obtained can be used for the same purposes as the correspondingly known prostaglandins.

Title: Tool for seamless pipe elbow mfr. - has die in two halves, each contg. semicircular channel with straight zone and curved zone matching bend required
Inventor: VAHLBRAUK KARL HEINZ
IPC: B21C37/28
Filed: 1977-02-23
Abstract: Tool set is used for mfg. seamless pipe elbows, using a die consisting of two halves, each contg. a semicircular channel with a straight zone and a curved zone matching the bend required. A pipe is pushed by a punch into straight zone so it travels over a curved mandrel located in curved zone, where the outer dia. of the mandrel matches the bore of the bend. Mandrel is mounted on a thrust pad assembly located on a pivot so the mandrel has the same centre of curvature as curved zone of the channel. The punch may be a round bar fitted with a centering end entering pipe; or be a ring contg. a centering mandrel. Pipe elbows can be made with a very small radius of curvature without folds or cracks and without any subsequent operations being necessary.
