Title: Target location and firing system - uses thermal image from rocket combined with electronic target marking on screen for adjustment
Inventor: ENDERS PAUL DIPL ING
IPC: G02B27/32
Filed: 1976-07-24
Abstract: The system for locating and destroying a target by a projectile has a daylight and night time aiming device. The missile is guided automatically to target by thermal image of the projectile and target generated by the night vision device in the night and in bad weather. The differential spectral radiation of the target and the rocket is used in the thermal radiation region of determining the position of the rocket relative to a reference direction. The rocket position is used for positioning an electronic target, mark in the thermal image in the field of vision of the night time viewing instrument. The rocket image forms the mark centre point and a deviation signal is generated by means of which the thermal image is continuously displaced so that the point of circular image of the rocket is always in the centre of the electronically generated target mark at the centre of the screen.

Patent DE-2701202-A1 (DE)
Inventor: MUELLER JUERGEN ING GRAD
IPC: G03G15/054
Filed: 1977-01-13
Abstract: The electron radiographic imaging camera has two electrodes (105, 106), which are spherically curved around the location of the X-ray source and against which the record carrier, which is formed by an elastic film (115) and introduced on a cylindrical track into the imaging camera, bears during the imaging process under the overpressure of the process gas enclosed in the imaging camera and with the aid of the pressure force of inflatable seals (107). In order to be able to obtain both a positive and a negative charge carrier in one operation without increasing the X-ray dosage, each of the two electrodes of the imaging camera is assigned a cylindrical guide track (120, 121) for a record carrier, and both guide tracks are connected by a deflecting device (124-127). Elastic intermediate seals (123) are arranged between the two guide tracks and transmit the pressure of the inflatable seals onto both films. <IMAGE>

Title: Terminal pin inserter for coil formers in TV equipment - uses air compressor and valves to indicate missing pins
Inventor: WUENSCHE JOACHIM ING GRAD
IPC: H01F41/10
Filed: 1977-02-03
Abstract: The terminal-pin inserter is for coil formers in TV equipment. It uses the increase in air pressure in a monitoring device to indicate that the pins have been inserted in the correct places and to move the inserting machine on to the next coil former. The monitoring device consists of valves (16, 17) coupled to a compressor and whose sprung plungers (20, 21) touch the tops of the inserted pins (9, 10). If a pin is present the plunger moves up (when its housing moves down) and closes an internal air outlet hole. When all the holes are closed the air pressure rises.

Patent DE-2734598-A1 (DE)
Inventor: HENNING ERWIN
IPC: D03D47/26
Filed: 1977-08-01
Abstract: For liberal weft patterning on wave-shaped machines, cut-to-length weft threads (16-19) of differing colour and/or material are fed via a multiple thread guide (15) to the apparatus for winding weft-thread carriers (2). After a specific thread length is reached, the selected different weft thread (16) is knotted in a knotting device (11), by means of a knotter (12), to the leading weft thread (18) fed to the winder (4), and the run-off end of the leading weft thread is cut off. The newly selected weft thread is thereupon fed continuously to the winder (4). It is thus possible, whilst maintaining a high working speed, to keep the number of winders low, in that weft threads from a plurality of supply bobbins (57-60) are fed uninterruptedly to an individual winder (4). <IMAGE>
Patent DE-2740492-A1 (DE)
Title: Pitot compressor for use with gas - incorporating liquid removal system, integral with gas inlet lines in the casing
Inventor: ERICKSON JOHN WALDEMAR
IPC: F04D1/12
Filed: 1977-09-08
Abstract: In a pitot compressor for use with a gas the gas is introduced into a rotating casing and after compression passes from the pitot tube into an outlet manifold lying along the axis of rotation. A separate liquid removal system is provided on the gas inlet line. This consists of passing the incoming stream though passages extending radially outward while at the same time imparting centrifugal energy to the steam. A U bend or similar trap is encountered in which the liquid accumulates. Removal of the accumulating liquor is accomplished by stand tubes located in the traps so that centrifugal energy of the liquid converts to static pressure and the liquid passes out of the casing by a small bore tube along the axis. The removal of liquids prior to entering the gas compression chamber avoids the need for gas liquid separation means on the periphery of the chamber where high centrifugal forces are operating, and the presence of unseparated liquid greatly increases the stress on the casing. Similarly the need to provided a separate liquid- sepg. station prior to the compressor is avoided.

Title: Heavy-duty, resin-bonded, glass-fibre profiles e.g. masts, lamp posts - reinforced against tensile and flexural overload by glass-fibre rods
Inventor: DUPPACH JOSEF
IPC: B29C53/80
Filed: 1978-05-23
Abstract: Profiles are reinforced with resin-impregnated glass-fibre strands, where mattings composed of parallel glass-fibre rovings which are connected by single fibres (monofils) are wound in several layers about a mandrel corresponding to the intended profile and coated with resin. Relatively very strong glass-fibre rods are incorporated between the mattings extending in direction of expected tensile stresses. These rods are arranged side-by-side at predetermined intervals upon the matting with which they are connected in wary pr weft fashion. The prods. easily absorb heavy tensile stresses such as may arise in high winds thus minimising the risk of fracture by flexural failure.

Abstract: Fluoroalkyl gp. contg. diorganopolysiloxanes with a viscosity of 6,20000000 cps at 25 degrees C are prepd. by (co)hydrolysis of dichlorosilanes of formula R1R2SiCl2 or R3R4SiCl2 (where R1 is RfCH2CH2, Rf is 1-10C perfluoroalkyl, R2 is 1-6C alkyl, vinyl or phenyl and R3 and R4 are as R2 or H); cyclisation of the (co)hydrolysate; and polymerisation of the cyclic mixt. by acid equilibration opt. in the presence of another cyclosiloxane (R3R4SiO)n (whre n is 3-6). The cyclic mixts. can be (co)polymerised with the usual acid catalyst and the use of expensive and pure fluoroalkyl contg. cyclotrisiloxanes is unnecessary. The (co)hydrolysate can be polymerised without further sepn. The low viscosity oils can be used as plasticisers, oil repelling agent defoamers or hydrolysis resistant hydraulic oils. The high viscosity prods. can be vulcanised to form silicone rubbers with resistance to swelling by oil e.g. seals for lubricating systems, fuel pipes and hydraulic systems.

Title: Digital control circuit for excitation thyristor in sync. motor - uses OR=gate coupled to two backwards counters and to anode of thyristor
Inventor: HOLWECK PETER DIPL ING
IPC: H02P25/03
Filed: 1978-08-26
Abstract: The digital control circuit produces triggering and turn-off pulses in accordance with the magnitude, polarity and frequency of the a.c. voltage induced. The latter enables a preset backwards counter when a given positive threshold is exceeded. The counter's output is passed to an OR-gate after the a.c. voltage has fallen below a negative threshold. A second preset backwards counter is enabled when the a.c. voltage passes through zero and passes its contents to the second input of the OR-gate. The OR-gate's output forms the turn-on pulses for the thyristor.
