Patent DE-2645025-A1 (DE)
Title: Self loading container for lorry - has servo operated support struts with synchronising controls at corners
Inventor: THIELE BERND
IPC: B60P1/64
Filed: 1976-10-06
Abstract: The self loading container has four vertical struts at the corners, the struts being extended by integral servo drives. The struts are extended to lift the container off the lorry, so that it can be driven away, after which the container is lowered to the ground. Transfer of loads is speeded without complex lifting gear. The servo drives are mechanical or hydraulic, with simple synchronising controls to ensure that all four struts are extended together. The rear struts can incorporate a servo tailgate hoist.

Title: Biologically active gas purification in closed vessel - with perforated corrugated floor plates and inactive granulate-supporting filter material
Inventor: ZANTOPP HERBERT
IPC: A61L9/00
Filed: 1976-11-19
Abstract: The filter material is container in a vessel, in which at least a portion of the wall or floor is in the form of a sieve or grating. The inlet for the dirty air is adjacent to the sieve or grating, while, while the outlet for purified air is remote from it. Pref., the bottom of the vessel comprises inclined surfaces, esp. with a perforated corrugated or undulating support element mounted on them. A granulate layer of inactive material, esp. plastics granulate, is mounted on the undulating, perforated floor. The device is used as a purifier for air discharge from a great variety of industrial and other processes. The appts. makes use of biologically active filter material such as compost. humas, peat and the like but protects them from the weather which is the principle disadvantages of biologically active filters of this type. In addn., the use of a perforated support floor ensures uniform distribution ofothe air flow across the cross-section of the filter.

Patent DE-2738029-A1 (DE)
Title: Filter with filter bed with or without carrier layer - with expansion of carrier layer or filter bed on flushing
Inventor: FOGELSTROEM BENGT
Filed: 1977-08-23
Abstract: Filter consisting of a filter bed with or without a special carrier layer has granules in the carrier layer, or in the filter bed without carrier layer, of which the density-to-size ratio causes expansion of the carrier layer or filter bed on flushing with a technologically and economically measured water flow. The density-to-size ratio also causes the rate of descent of the larger granules to be higher than that of the smaller granules. The granules pref. consist of anthracite and/or plastic, are spherical in the latter case, and have a density 1.6-1.2. Efficient cleaning of the whole filter can thus be performed with measured quantities of water.

Title: Valve part in fuel injection system - controls air by=pass cross=section and is operable by bimetal spring of pressure control valve
Inventor: WILFERT THOMAS
IPC: F02M69/38
Filed: 1977-12-17
Abstract: The fuel injection installation for i/c engines has a measurement unit in the suction pipe and a throttle valve operable at will, the measurement unit being moved against the return force corresponding to the air quantity passing through. It accordingly displaces a control slide unit of a valve in the fuel feed line for measurement of the amount of fuel commensurate to the air intake quantity. A pressure control valve uses a bi-metal spring acting dependent upon temperature and/or time, and a by-pass connects the suction pipe section upstream and downstream of the throttle valve. The valve part (56) controlling the cross-section of the air by-pass (54) is operable by means of the bi-metal spring (49) of the pressure control valve (42).

Title: Spinning yarn break analysis - has an exchangeable data store on servicing units for interrogation
Inventor: IGEL WOLFGANG DIPL ING
IPC: D01H13/00
Filed: 1978-05-24
Abstract: In a yarn spinning or twisting assembly where mobile maintenance units travel round the spinning stations, to repair yarn breaks and other faults, each mobile unit has a store to register the number of faults, in the form of a slide-in unit for easy exchanger. There are fewer data stores for the spinning assembly as there are mobile maintenance units. The system gives a data store which can be removed for interrogation, easily, so that there is no need for a large store to retain information on up to thousands of faults repaired.

Title: Safety device for laser endoscope - has beam directed onto converter connected to comparison circuit to test radiation level before use
Inventor: EICHLER JUERGEN PROF DR
IPC: A61B18/20
Filed: 1978-07-26
Abstract: The laser endoscope safety and control system ensures that the instrument is operating correctly, e.g. if the optical system is obscured. the light conductor tube (16) has a grip portion (12) preceding its tip (14) which is inserted in a support (22) which incorporates the safety system. The lowermost part of the tip is in line with a screen with an opening so that the laser beam falls onto a converter (28) such as a phototransistor or photodiode or a thermal element or semiconductor. This gives an output which is measured by a signal converter (30) which measures the laser beam load or density and operates a red indicator bulb (34) if the device is not operating correctly or operates a green bulb (32) if it is operating correctly. The converter incorporates a digital circuit and an equaliser which compares the signal with a standard signal.
