Title: Hammer head foundation for earthquake endangered regions - is for machines whose connections to steam gas or power lines could otherwise be damaged
Inventor: HERTEL WILHELM DIPL ING
IPC: E02D27/44
Filed: 1975-01-21
Abstract: The hammer head foundation has an I-shape which is mounted with its upper flange on springs or similar elastic damping means. Furthermore the centre of gravity (S) of the foundation is at the same level as the elastic mounting. In this way during horizontal earthquake shocks, tilting and with it the scaled up deflections do not occur and moreover the reaction forces of support on the fixed construction scarcely vary in the vertical direction; hence the static friction for the dampers persists. Furthermore the polar moment of inertia of the total aggregate is substantially increased about its longitudinal axis so that the quietness of the machine is improved.

Title: Mfr. of a flexible textile hose - having rubber or plastics inner and outer mantle layers, achieved by first lining it, then turning inside out, and then lining it again
IPC: B29C67/00
Filed: 1975-03-04
Abstract: Mfr. of a flexible (esp. tectiole) hose or pipe having a rubber of plastics lining and coating, comprises (i) lining it with rubber or plastics (which will subsequently be its outer coating); (ii) turning it inside out; (iii) lining it again with rubber or plastics.

The end is then turned over the fastened, press. -tight at the outside of the socket. Finally, the hose is forced out of the tube by application of the press. medium between it and the tube and thereby turned inside out. Hoses of any desired lengths may be lined and coated. The equipment needed to preform the process is inexpensive and of simple construction.
Patent DE-2511834-A1 (DE)
Title: Continuously casting metal strip between endless belts - which are accurately located against supports by differential fluid pressure
Inventor: BAKER WILLIAM ALBERT
IPC: B22D11/06
Filed: 1975-03-18
Abstract: The mould is formed by a pair of belts to the reverse sides of which coolant is applied; at the mould-forming region the belts are backed by spaced supports against which they are pressed by a differential fluid pressure independent of metal in the mould space, that pressure being a function of the spacing of the supports and of the belt thickness whereby buckling of the belt is prevented. Pref. the mutual inclination of the belts is variable to provide adjustment of the mould space taper, while the belt supports are located within a casing in contact with the belt and maintained at sub-atmospheric pressure to extract water and to hold the belt against its supports. The spacing of the supports should be less than 50 times the belt thickness. The system is especially useful for casting Al and its alloys, or Zn.

Title: Resilient door closing device - is weight and chain or spring spanning angle between door and frame
Inventor: ZARGES WALTHER DIPL ING
IPC: E05F1/10
Filed: 1975-03-20
Abstract: The door shutting device has a tensile force exerted between door leaf and frame by means of weights and springs. The direction of action of the tensile force lies along a straight line between the attachment points on the door and frame and the spring and weight constitute the hypotenuse of the triangle formed by the door, frame and tensioner device when the door is closed. When the door is wide open the coupling line of both static points on the frame and door forms an angle, the apex of which is within a solid body (15) hels some distance from the door or frame.

Title: Test system for digital communications amplifiers - has logic in repeater amplifiers producing test signals
Inventor: MARKO HANS PROF DR ING
IPC: H04B17/40
Filed: 1975-05-06
Abstract: The test system, avoids having to bridge both signal paths by including logic circuits in each amplifier that generate a low frequency test signal at the output of the amplifier in response to certain input criteria. The LF test signal is transmitted over the line as a code combination of digital signals, repeating itself periodically. A bistable circuit responds on receipt of these signals and generates an output square wave of twice the period of the LF test signal transmitted over the line.

Title: Circuit bringing function unit to stand still synchronised to pulses - incorporates logic coupling alarm to duty pulse of unit
Inventor: HOHNBERG LUTZ DIPL ING
IPC: H02H3/02
Filed: 1975-05-09
Abstract: The circuit for bringing a function unit to a standstill in synchronism with a pulse and to maintain this passive condition in accordance with an alarm signal, is used for monitoring function units in data processing systems. The system incorporates a logic circuit which couples the alarm signal to the duty pulse of the function unit. If necessary, it will place a reset signal at the reset input of the function units which is used to bring the function unit to a standstill. The alarm signal is fed to the input of a delay line, which holds back the alarm signal for at least one period of the duty cycle at the reset input.

Title: Automatic typewriter with data store - screen between keyboard and platen for examination of text line selected
Inventor: STAAR MARCEL JULES HELENE
IPC: B41J3/46
Filed: 1975-07-03
Abstract: A code corresponds to all the data typed manually, which can be stored in a memory unit and extracted from it for modification, consulation etc. An examination screen is placed between the platen and the keyboard, with a length equal to a line of text being used. Line selection is by the mechanism of the machine, e.g. the command to return to a particular line. It can be so designed that each manual or automatic movement of the platen to change from one line to another automatically selects the following or previous line to be displayed.
Patent DE-2531096-A1 (DE)
Title: Fault location in symmetrical DC signal transmission systems - has quadrature resistor between repeater amplifiers of opposite polarity
Inventor: PICHLMAYER ERWIN DIPL ING
IPC: H04B17/40
Filed: 1975-07-11
Abstract: A fault location system is for transmission systems having repeater amplifiers across the positive and negative parallel lines fed with a power supply through matching units. The centre points of each amplifier per repeater stage are connected by a quadrature resistor of high ohmic value. In the event of a transmission line break the position can be located by a reading on an indicating instrument which shows the sum of the current through each quadrature resistor still connected. It follows that all the resistors have to be identical. They represent only a small drain on the supply system and, by elimination of the hitherto connected series diode, allow much simpler and quicker fault location.
Patent DE-2549829-A1 (DE)
Title: Frequency modulator avoiding build:up time - has extra capacitor switched in and out of resonant circuit to give clean frequency transitions
Inventor: TRETOW JOCHEN ING GRAD
IPC: H04L27/20
Filed: 1975-11-04
Abstract: The frequency modulator has an extra capacitor (4d) switched in and out of the resonant circuit (jb, 4c) of an HF oscillator (4) when the alternating voltage passes through zero. The capacitor has the same effect as switching between two separate oscillators but does not have the disadvantage of causing unreproduceable transitions with different spectra. Build-up time is also avoided. The oscillator (4) output is fed back to a zero detector (3) that controls the application (2) of pulses (1) to a transistor (4a). The extra capacitor is coupled is connected to the collector of teh transistor.

Title: Container for ornamental plants, composting, etc. - formed by treads of old tyres, inverted and clipped together
Inventor: DOERING ERICH
IPC: A01G9/02
Filed: 1975-11-21
Abstract: The containers are built up from cylindrical rings comprising the treads of old vehicle tyres from which the sides have been cut away. The rings are turned inside out to give a smooth exterior, and they are held together by clips formed from discs with two slots which connect adjacent rings leaving a space between them which serves for ventilation. The cheeks of the tyres are cut off so that when the rings are turned inside out, their outer edges are higher than those inside, so that rain will tend to run into the container. The material is cheaper and more readily available of natural and other container forming materials.
