Title: Battery discharge indicator lamp and cct. - has sufficient hysteresis to prevent flickering illumination
Inventor: CRANTZ DIETER DIPL ING
IPC: H01M10/48
Filed: 1974-02-20
Abstract: The circuit is intended to give warning, by the switching in of a lamp, that the permitted discharge level of the battery feeding the load has been reached. The hysteresis effect between switch on and switch off of the lamp is arranged to be sufficiently wide that its limits lie outside the normal voltage fluctuations set up by the lead. The uncertain indication of a flickering light is thus avoided. A practical circuit may be realised using two transistors of opposite type for controlling switch on and off respectively. A threshold circuit can be added which in the normal state requires no current.

Title: Utilisation of rubbish and other combustible waste - dried waste is evaporated and compressed and fed with air to engine combustion chamber
IPC: F02B43/08
Filed: 1974-03-15
Abstract: Rubbish and other combustible waste materials, are utilised by drying the waste directly or indirectly by the engine exhaust gases. The dried waste is evaporated by part combustion with air support under over pressure. The resulting hot combustion gas, while regaining its heat to gasify the waste, is cooled, isothermically compressed, then reheated by waste heat. The compressed, hot combustion gas is burned in a constant pressure piston engine. The combustion air necessary is continuously isothermally compressed, then heated by the engine exhaust gases and fed via special lines in approximately stoichiometric proportions to the combustion gas to the engine combustion chamber.

Title: Cylindrical breech bolt mechanism for shotguns - has expansion spring ring locking mechanism actuated by bolt handle
Inventor: ZEDROSSER ULRICH
IPC: F41A3/48
Filed: 1974-04-19
Abstract: The rotary cylindrical breech bolt is used for shotguns and for sporting rifles. The bolt is locked in the firing position by expansion spring rings which are held in a separate tube length which is screwed into the bolt sleeve. The locking spring rings are held in the breech bolt chamber tubular rear part. The bolt is actuated by the handle which expands the spring rings via the spreading element in the chamber rear part. These spreading elements can be balls or rollers. The bolt has a central cylindrical part with notches for these elements which are forced out of these notches for locking the bolt for firing. This arrangement does not require deeply machined grooves in the bolt chamber, and relatively shallow projecting springs engage uniformly the circular, shallow grooves in the locking sleeve which is readily machined.

Title: Overlapping-rabbet-edged rectangular building panel - with trapezoid sectored rabbets alternately covering planes
Inventor: HEUSSER ERHARD
IPC: E04C2/38
Filed: 1974-05-06
Abstract: The building panel is of oblong or square shape in plan and has rabbets at the edges for connection the adjoining panels where the rabbets overlap each other. These rabbet folds are in the form of trapezoid sectors, which alternately have covering planes of different heights along each panel edge. The division of each pair of interfacing panel edges are mutually turned about 180 deg., and the sectors of a pair of adjoining panel edges form an overlapping area, while those of another pair form an overlapped area. Some covering planes may lie in one-third of the panel thickness, and others in two-thrids of this. Successive sectors along an edge may be of alternately different sizes. Security against horizontal displacement is achieved.

Title: Septg chemical solns using semi-permeable membrane processes - using series of conical porous supports mounted along separator axis
Inventor: SKRABAK MICHAL PROF
IPC: B01D63/00
Filed: 1974-08-20
Abstract: System for separation of chemical solns. by semipermeable membrane processes consists of passing the soln. through narrow passages formed by a series of coaxially mounted porous cones in a circular housing, each side of the cones being covered by a semipermeable membrane. The soln. can flow in both directions across the cones, both convergent and divergent. A specific embodiment uses alternate converging and diverging flow along the unit. For use with semi-permeable processes such as reverse osmosis, ultrafiltration, electro-dialysis, etc. The process solves one of the basic problems in unit construction for high pressure separation processes. It gives better hydro-dynamic conditions, a rise in process efficiency and a reduction in the constructional space per unit volume. It is of universal application for these processes.

Title: Non miscible liquids esp solvent and water separated - in long settling tank with float in close fitting chamber
Inventor: SCHMITT ROLF DIETER
IPC: B01D17/02
Filed: 1974-10-25
Abstract: A separator for continuously separating two non-mixing liquids of different densities comprises a settling tank with a low level outlet for the heavier liquid, a high level outlet for the lighter liquid and a regulating float which floats in the heavier liquid but sinks in the lighter. The deeper end of the settling tank merges into a float chamber closely surrounding the float; the bottom of this chamber has an outlet opening for the heavier liquid, which when the float sinks is obturated by a valve plug, esp. a rubber-elastic ball, fixed to the bottom of the float. The float and float chamber are pref. both cylindrical. Separator is esp. for separating solvent-water mixt. resulting from the desorption of activated carbon absorbers which have separated organic solvents from discharged air. The solvent, e.g. a chlorinated hydrocarbon, is the heavy liquid. Separation is positive and effective. The arrangement is simple to construct and operate, and provides a long settling path in a compact layout.

Title: Hydraulic tailgate hoist for lorry - uses very short lever mounted on main lever to provide compact support
Inventor: FELKEL GEORG
IPC: B60P1/44
Filed: 1974-11-20
Abstract: The hydraulically operated tailgate hoist (7) is hinged on the chassis support (2) by a main lever (3) on each side, with the main lever operated by a hydraulic ram (4) between it and the support. A shorter lever (9) is hinged between the tailgate and the main lever and is shaped in such a way that by using a second set of rams (5) the tailgate is lifted in a horizontal setting, with only a relatively low profile of levers. This enables the tailgate to be accommodated under the load platform. The second rams are linked to the support by control levers (11) which enable the tailgate angle to be altered, and even raised into a vertical position.

Patent DE-2462305-A1 (DE)
Title: Building element made from wet fibre mat contg. gypsum - and coated with stripper for easy removal from forming roll
IPC: B28B1/42
Filed: 1974-10-15
Abstract: Building elements are made from a mat consisting of fibres mixed with a sulphate binder and water in excess of the amt. needed for the setting of the binder. The mat is fed on a conveyor belt permeable to water, past suction units removing the surplus water, and then wound onto a forming roll where a dry sulphate binder is spread over the surface of the second and subsequent layers being wound onto the roll. Dry fibres or a powdered stripping agent is spread over the surface of the first layer of the mat facing the roll before the first layer is wound onto the roll. Difficulties were previously experienced in removing the sheet or panel blank from the forming roll as part of the mat adhered to the roll surface, producing faulty sheets and also leaving lumps on the roll. The present invention permits easy stripping of the sheet or panels from the forming roll.
