Title: Screwless clip for ceramic pipes - has lugs cut and bent out from one strip end and teeth on other
Inventor: RASMUSSEN JOERGEN SKAFTE
IPC: F16L21/00
Filed: 1978-08-03
Abstract: The screwless clip of strip material joins two pipe ends together, the overlapping strip ends engaging together by radial teeth and fitting over a sealing sleeve of resilient material, lateral flanges on the strip fit round the sleeve ends. The teeth are formed by cutting lugs (22) out of the strip material and pressing them radially outwards at one end, while teeth (26) on the other strip end engage underneath them. These latter teeth can be formed by the edges of openings (24) in the plane of the strip, and through which the lugs fit.

Title: Non-contact sensor control of power assisted clutch for road vehicles - detects approach of clutch plates against flywheel by proximity sensor to control actuating force
Inventor: LOEHMANN BERTHOLD
IPC: F16D25/12
Filed: 1979-04-26
Abstract: Control of the actuating force in power assisted friction clutches used on heavy road vehicles is provided by non-contact sensing of the point of coupling. Power is transmitted from a rotating flywheel (1) to an output shaft over a clutch plate (2) that is moved axially by force provided by a pneumatically powered linear actuator (11), operating on a lever assembly. The flywheel carries a number of small pins (3) that are spring-biased (9) to project beyond the face surface. As the clutch plate contacts the pins, levers (4) are pivoted to move a disc (5) nearer to a non-contact proxitivity sensor (6). The sensor output may be used to control the pressure applied to the clutch actuator to provide smooth engagement.

Title: Sprung leg for high-performance aircraft landing gear - has controllable force-absorbing elements for peak loads only, in addition to spring and shock absorber
Inventor: KRAUSS ARNULF DIPL ING
IPC: B64C25/60
Filed: 1979-05-18
Abstract: The sprung leg, for landing gear of aircraft, is for use, where conditions can arise during landing and taxiing on the ground, which prod. unacceptably high peak loads in the leg. To cope with these, the conventional arrangement involving a spring and a shock absorber has one or more force-transmitting elements added. These elements are controllable and are operated in such a way, using calculated values of load peaks, that excessive stress in the wheel and the associated structure is prevented without affecting the normal static-load level at the basic spring.

Title: Telephone appts. exchange dialling circuit - uses oscillator time bursts through Schmitt trigger into integrated circuitry to determine pulsed transfer to line
Inventor: DIRR JOSEF ING GRAD
IPC: H04M1/26
Filed: 1979-05-25
Abstract: The subscriber presses a push-button (T1 and T1-T14) and a circuit is made via a relay (B). One relay contact (5b) switches on an oscillator (OS2), whose output goes, via a Schmitt trigger (ST), to an AND-gate (8u). The signal is passed by the gate into an integrated circuit (2GE) which controls the signal length and switches the oscillator off. The duration, for which the oscillator is on, determines the signal sent to the exchange by the integrated circuitry (2GE, 2GS). Several involved and comprehensive alternatives are described whereby different pulsing rates through relays are available.

Title: Sonotrode for ultrasonic resistance welding rig - has current connection through diaphragm flange in vibration node
Inventor: RASKE HANS
IPC: B23K11/12
Filed: 1979-07-13
Abstract: The sonotrode of a combined ultrasonic and resistance welding rig is designed as the resistance welding electrode. Its connection to a welding transformer is made through a diaphragm with a flange. Its effective plane of vibration lies at right angles to the longitudinal vibrations of the sonotrode and passes through a vibration node. The flange is pref. joined by a thin annular web to the groove in which a split clamp acts as the current supply. Arrangement prevents loosening of the current supply connections and unreliable welding results. The contact resistance remains unchanged. Any existing vibration in the node are attenuated.
Patent DE-2929402-A1 (DE)
Title: Medium voltage solid conductor power cable - has contact with semiconducting screen ensured by deliberate irregularities formed in conductor surface
Inventor: LEUCHS OTTMAR DIPL CHEM DR
IPC: H01B9/00
Filed: 1979-07-20
Abstract: The conductor design ensures good bonding between the inner semiconducting sheath (7) and the solid conductor (5). A good bond ensures that there are no areas of high electric stress. In addition, and especially for cables with a solid aluminium conductor, the penetration of moisture between conductor and sheath is prevented. A good bond is ensured by making the surface of the solid conductor irregular. For example is can be given a surface comprising numerous indentations (6) which act as a key for the semiconducting sheath (7) when it is extruded onto the core. Alternatively, the surface may have one or more spiral ridges along its entire length. A further possibility is to wrap the solid conductor with a layer of thin wires before extruding the sheath.

Title: Bridge alignment control - with fixed pairs of markings and sensors on each propulsion unit responding to them
Inventor: KETTENBACH KARL ING GRAD
IPC: B66C9/16
Filed: 1979-08-30
Abstract: Bridges with independent propulsion units at each end, e.g. structures for jamming by misalignment by fitted markings in regular distances along both tracks. These are arranged in pairs to indicate the correct alignment. When a sensor on the bridge ends indicates that the bridge is not in alignment, the propulsion unit which first coincided with a marking is stopped and is only restarted when the second propulsion unit has reached its marking. This creates a simple control system for the correct alignment of such bridges.
