Title: Injection-mould for mfr. of thermoplastics fittings with bushing - has adjustable core with projection for shaping groove
Inventor: ANGER ANTON
IPC: B29C45/44
Filed: 1977-12-23
Abstract: Injection-mould for mfr. of thermoplastics fittings and tube connections with >=1 bushing with annular groove spaced away from their end(s) whose depth is greater than the wall thickness i.e. in the order of 10% of inner dia. or >=5mm in the case of inner dias. above 50mm, is claimed. The mould comprises a 2- or multi-part outer mould and a mould core which together define a mould nest determining the final shape of the fitting. The core is adjustable in machine direction to facilitate removal of the moulding, and is provided with an annular projection for shaping the groove. This projection is firmly connected with the core with which it pref. forms an integral unit, so that it is displaceable, together with the core, after the injection step, and can be pulled out of the still-thermoelastic bushing whilst briefly expanding the same. Pref. a special mould component is provided for shaping the outer contours of the end of the bushing and the groove at the zone of greatest dia.

Patent DE-2830411-A1 (DE)
Title: Cast iron inoculation wire - with inoculation medium in space between solid core and outer braid
Inventor: DOLIWAM HEINZ-ULRICH FRIEDBERG
IPC: C21C7/00
Filed: 1978-07-07
Abstract: A wire, used to introduce an inoculation medium in special cast iron qualities, consists of a central core of a carbon or alloy steel which is surrounded by a meshed braid. The inoculation medium is contained between the core and the braid and in the meshes of the braid. This releases the inoculation medium instantly during the pouring operation and is not delayed by the time required to melt a solid sheath. The greater flexibility allows thicker diameters to be used so that the feed mechanisms can be simplfied. The cast iron produced is of better quality because the additive is distributed more uniformly.

Patent DE-2840599-A1 (DE)
Title: Waterproof sheet for sealing buildings - has polyethylene substrate sheet with self-adhesive bituminised synthetic rubber coating covered with silicone paper
IPC: E04D5/10
Filed: 1978-09-18
Abstract: Sheet for sealing buildings against water consists of a polyethylene substrate sheet coated on one side with synthetic rubber mixed with bitumen. The other side of this coating is covered with silicone paper. The self-adhesive sheet can be used instead of paint. It can be made in large sizes and rolled up to save storage space. A relatively thin supporting sheet can be used, since the adhesive and sealing coating is dimensionally stable, which facilitates the prodn. of water-tight lap joints and does not reduce the flexibility. Pref. the synthetic rubber is a polystyrene/polybutadiene/polystyrene block elastomer.

Title: Double row bearing for vehicle driven wheel - has flush mounting retaining ring to prevent distortion of races
Inventor: MARKFELDER GUENTER DIPL ING
IPC: B60B27/00
Filed: 1978-10-06
Abstract: The double row bearing is for a hub in which one of the races has a separate inner ring (6) which is located on a sloping face of the main ring. The outer flange (6') of the separate ring lies flush with the outer flange (9) of the main ring when the bearing is closed so that the securing force on the bearing is not transmitted to the bearing. The hub nut (8) can be tightened without distortion to the bearing races. Bearing play is taken up by packing washers and oil seals.

Abstract: The resilient disc coupling comprises a hub (11) carrying a central disc (10) with interconnected discs (20, 21) arranged to either side of the disc and capable of limited angular rotation. The disc has a number of circumferentially spaced openings for resilient coupling elements (30, 32) which engage recesses (22, 23) in the discs (20, 21). The discs are completely solid, except for a central opening (28) for a shaft, so that they form a totally enclosed liq. tight chamber (9) between them which contains the disc and can be filled with lubricant. Stops may be provided to limit relative angular rotation and throttles permit the lubricant to act as a damping fluid.

Title: MIcroprocessor controlled telephone appts. - has fixed time base interrupt signal used for number dialling selection
Inventor: GRAVENHORST PETER
IPC: H04M1/31
Filed: 1979-08-16
Abstract: The telephone appts. has a microprocessor employed for number dialling selection. The interrupt input (IRQ) of the microprocessor (1) is connected continuously to an oscillator or impulse generator (3). The interrupt circuit calls up a programme for generating the number to be dialled. The microprocessor is connected via a data bus (4) to a read-write memory (1) and a programme memory (6) which in turn are connected via peripheral equipment (7) to a key board (8). The entry of a required number on the key board results in its transmission from the microprocessor output (1.3) during an interrupt period. There is reduced programming requirements and the possibility of using standard oscillators for the interrupt signal generator, since the need for accurate timing to coincide with the execution of programme steos is avoided.
Patent DE-2935814-A1 (DE)
Title: Hydraulic holding down device for deep drawing press - has spring loaded reducing valve to accommodate changes in viscosity
Inventor: ETSCHEID HERMANN
IPC: B21D24/08
Filed: 1979-09-05
Abstract: A deep drawing press has a holding down device actuated by hydraulic pressure exerted on a piston (9) which operates in the inner cylinder (6). The inner cylinder (6) communicates through a pressure reducing valve (21) with the outer annulus cylinder (7). The pressure in this annular cylinder is maintained constant by being connected to a large reservoir of compressed air (16). This addition to the patent is concerned with the fitting of a spring (213) to the reducing valve (21) which counteracts any tendency for the hydraulic pressure to change as a result of a change in viscosity due to changes in temperature of the oil.

Title: Switching system for electronic clock - uses control signals obtained from filters connected to mains supply in place of timing pulses
Inventor: BECHLEM DETLEF
IPC: G04G7/00
Filed: 1980-02-08
Abstract: The electronic clock with a digital indicator uses a regulating system with control signals which can be obtained by using the frequency of the main supply as a reference. These control signals consist of a starting signal, a closure signal and switching signals divided by different periods of time. These can be superimposed on the mains frequency. These can be used to cancel the normal timing pulses from the clock pulse generator. This generator is connected to a counting system with decoders and drivers for the display system, in which are included further counters which store the control signals, and release them after a given period of time, operated by a gating arrangement. The control signals are obtained from a set of filters connected to the mains supply.
