Title: Blowing plastics tube - with gradual cooling in final flattened form
Inventor: UPMEIER HARTMUT DIPL ING
IPC: B29C48/03
Filed: 1971-12-23
Abstract: Parent patent described a blowing appts. producing plastics sheet from blown tubing; the blown tubing as it left the blowing device moved vertically upwards, was initially flattened as it started to harden and then turned over through 180 degrees to descend again, passed along a stretch where it was temporarily reinflated, and was then finally flattened before entering an oscillating device which ensured that linear irregularities in the final sheet ranged from side to side across the spool of finished material. Here, >=2 contact cooling rolls are incorporated between the final flattening device and the oscillating mechanism, thus ensuring progressive cooling of the sheet, resu lting in improvement to its structure.

Title: Switch-on current surge suppressor for power supply system - has attenuating resistor connected during interruptions and switch-on
Inventor: WOCHELE GUENTER
IPC: H02H9/00
Filed: 1973-09-27
Abstract: The current surge suppression circuit is operative during switching-on in power supply systems used with communications equipment. Two anti-parallel thyristors are connected across a resistor that attenuates the current surges at switch-on. These thyristors are controlled by another thyristor which is itself controlled so that the attenuating resistor is short circuited after a given time has elapsed after switch-on. During interruptions in the supply the circuit behaves as it would at switch-off, i.e. the bridging thyristors are turned off and the attenuating resistor switched-in ready to attenuate current surges when the supply returns.

Title: Wideband signal transmission system - with signal level continuously adjustable without resistant potentiometers
Inventor: HABLIZEL PETER DIPL-ING
IPC: H04B3/04
Filed: 1973-10-23
Abstract: A part of the energy of the whole frequency band, whose level is to be adjusted, is branched off and its phase is shifted by K x pi, where K is an integer. This part amplitude is uniformly adjusted over the whole frequency range to a value corresponding to the adjustment error of the frequency band to be adjusted. This shifted in phase part is then added to the whole band. A branching off circuit has one input and two outputs, one of which is connected to a phase shifter for the main signal, and the other to a phase-shifter for the correcting signal. The phase shifters outputs are connected together through a summating circuit, continuously variable by a capacitor. This device is inserted into an echo suppressor.

Title: Forming contact point of carrier - comprises pressing ball of contact material into receiver of carrier
Inventor: BERGINSKI WERNER
IPC: B21K25/00
Filed: 1974-01-08
Abstract: Contact points, of contact material, are formed on a carrier. A ball of the material is pressed, under plastic deformation, into a receiver of the carrier, bringing the spherical segment forming the contact point into the required shape for the contact surface. Preferably, with a plate-shaped carrier, the ball is pressed onto a receiving surface. Preferably, with a plate shaped carrier, the ball is pressed into a receiving passage of transverse dimension smaller than the ball diameter, and a rivet head, which forms the contact head, a rivet shaft, and a closing head, are formed. The deformation occurs while electric current is passing. The contact head is given the required shape while ensuring a good electrical contact with the carrier. The vol. of contact material is minimised.

Title: Submersible cover for a swimming bath - with automatic push button control for floating or sinking very quickly
Inventor: LOHMANN FRIEDRICH
IPC: E04H4/06
Filed: 1974-02-11
Abstract: A cover for a swimming bath comprises a flexible sheet of a rot-, shear- and aging-proof material, or other suitable support, for chambers which can be filed with air so that the cover floats on the surface of the water when the bath is not in use, and evacuated quickly so that the assembly sinks to the bottom. The chambers together with the cover, the solenoid controlled valves are switched over for the compressor to evacuate the air. The plastic sheet of the cover is reinforced by rails or strips of plastic material, with perforations through which the water can flow from the upper to the underside, and vice versa; the cover being of a size equal to about 95% of the area of the bath. The ducts leading the air to and from the compressor and the chambers extend the length of the long sides of the cover and beneath it, and are joined to the air chambers by nipples. In the electrical circuit, an adjustable timer is arranged to switch off the compressor after a predetermined interval, and there is further a pressure switch opening the circuit when the air pressure reaches the safety limit. Device can be easily handled by one person. Difficulties with the driving out of water, causing tiltint and jamming of the cover, do not arise.

Title: Chenille yarn mfg. process - imposes a ballooning effect on two cores for effect yarn insertion and twisting into place
Inventor: LOPEZ JUBANY MODESTO
IPC: D04D3/00
Filed: 1974-03-16
Abstract: The process to manufacture a chenille yarn, composed of two or more cores with lengths of effect yarns, has a feed mechanism to draw the cores from their supply bobbins attached to the machine frame together with a feed for the effect yarn so that by developing a ballooning effect in the passage of the cores the effect yarn is wound round the first core and then trapped by the twisting effect to wind round the second core. The location of the bobbins in relation to the operating components of the machine gives a relatively small unit, with the chenille yarn produced in a structured form with pre-set introduction of the effect yarn to divide the windings of the twisted cores.

Title: Long acting insulin compstns - contg. a crystalline insulin suspension and des phenyl alanine insulin soln.
Inventor: MAGER ADOLF DR
IPC: A61K38/28
Filed: 1974-04-13
Abstract: Compsns. contg. crystalline insulin in aq. suspension and des-phenylalanine B'-insulin from the same species and 25-80 mug Zn++ per 100 I U of insulin, are long-acting and useful in the treatment of Diabetes Mellitus. Conventional long-acting insulin compsns. contain crystalline insulin of one species and an insulin soln. from a different species in order to prevent the dissolved insulin from crystallising. This leads to the development of antibodies against both types of insulin-preventing the possibility of changing to a different insulin after a few years. By using the novel compsns. these difficulties are not encountered.
