Title: Electromagnetic control system for camera - has electromagnet core with rectangular hysteresis properties and impulse generators
Inventor: AIZAWA HIROSHI
IPC: G03B17/42
Filed: 1975-07-11
Abstract: An electromagnetic activation device to control the release of internal mechanism of a photographic camera from their cocked setting has an electromagnet (M) with a single field coil with a magnetic core. The magnetic properties of the core have a rectangular type hysteresis curve. An electronic control device (C1, VR1, Tr1, Tr2, B) produce the "contact" or "disconnect" impulses of opposing polarity such that the "connect" impulse is applied to the field coil for only a short time and magnetic flux is built up. When the "disconnect" impulse is applied to the field coil no magnetic flux is built up in the core and release of the internal mechanisms can take place. Two devices are used to produce the "connect" or "disconnect" impulses separably.

Title: Telescopic and foldable umbrella - has outer arm section links extending and retracting pivot joints on telescoping inner links
Inventor: WEBER HEINZ
IPC: A45B19/00
Filed: 1975-07-21
Abstract: The telescopic umbrella has a number of arms in sections, the innermost ones telescoping and the outermost one folding and coupled by a link (11) to the slide link. The pivot joint between the slide link and the arm section coupled to it slides on the latter in the lengthwise direction. Thus when folded by moving the slide towards the handle the arm sections are first brought parallel to the stem without retracting. The folding sections then have their free ends swung round towards the pivot ring by further movement of the slide towards the handle. The pivot joint between the slide link and the innermost branch section works in a guide independently of the telescopic portion of the section. the link to the outermost portion extends and retracts this joint.

Title: Auxiliary electric drive for car - has battery driven motor near drive axle to provide very low traffic speeds
Inventor: SOMMERER ERICH
IPC: B60K17/16
Filed: 1976-03-18
Abstract: An electric motor has an inertially operated drive cog, similar to a starter bendix and mounted near the driving axle (41, 42) to drive that axle in the forward direction when a dashboard switch is closed. The motor drives the car without turning the engine, which is isolated from the auxiliary drive by the clutch. The system enables the car to inch forward in dense traffic without having to start the internal combustion engine every time the car moves forward. It also enables the engine to be switched off in such conditions. The motor uses no more power than would the starter motor through repetitive use. The system reduces pollution in dense city traffic jams. The battery is recharged normally when the vehicle drives on its engine.

Patent DE-2614127-A1 (DE)
Inventor: BOSCHUNG MARCEL
IPC: E02F3/80
Filed: 1976-04-01
Abstract: The attachment plate (8) for working implements, for example a dozer blade (11), is usually secured by lower lifting arms (3), which are actuable by lifting cylinders (4), and by upper links. The different length of lifting arms and links does not produce an exact parallel guidance. The upper link is therefore split in two and the adjacent ends are articulated on a sliding piece (6). The sliding piece slides in a guide (9) which is connected to the lifting arms (3). This produces an improved parallel guidance. Furthermore, the front link part (7) can be constructed as an adjusting element. <IMAGE>

Title: Spinning endless filaments from molten polymers - at very high speeds with an efficient, relatively short, cooling shaft
Inventor: LANDENBERGER PETER DIPL PHYS D
IPC: D01D5/092
Filed: 1976-04-08
Abstract: Endless filaments of a synthetic polymer extruded through a spinning plate, are subjected to a stream of gas as they pass through a cooling zone, and are wound at speeds of 3000 to 6000 m/min. In this operation they are drawn and stretched to a considerable degree. The lower end of the cooling zone is constricted to outlets allowing the passage of only one bundle of filaments each. Pref. at this point also, where the filaments assemble into bundles, surfactant materials are applied, and below the cooling zone, before winding, the bundles of filament are processed, esp. heated, texturised and/or steamed. The freshly spun yarns are cooled intensively in the shortest possible cooling zone. At the constricted outlet, the yarns are already formed into bundles so that guiding is easy and there is no fluttering of long lengths of filaments. The process is suitable for polyesters, polyamides, polypropylenes with gauges of the separate yarns from 1.5 to 20 dtex.

Title: Reconstructed double hologram interferogram - uses double impulse laser read alongside photograph in medical applications
Inventor: GRUENEWALD KLAUS DIPL PHYS DR
IPC: G01B9/021
Filed: 1976-05-11
Abstract: Evidence of pathological change in biological tissue is to be sought by guiding the output of a known double-impulse laser (two 20n sec pules at a 100 - 500 mu sec interval) through an endoscope to produce a pair of holograms on the same plate. The reconstructed hologram gives an interference pattern representing the movement of the tissue in the time interval. The equipment used includes a set of mirrors, (28, 30) which preserve the holographic reference beam until the return signal from the endoscope arrives. To facilitate interpretation an ordinary photograph (pref. colour transparency) of the same subject will be made immediately after the second holographic exposure, using either a flash bulb or a third laser pulse as illumination.
