Patent DE-3118081-A1 (DE)
Title: Self-adjustable, stepped shock absorber
Inventor: DOMEK JOHN A
IPC: F16F9/48
Filed: 1981-05-07
Abstract: In the case of a hydraulic shock absorber, a piston, responding to an impact load, moves in a cylinder and presses a pressure medium, located therein, through one or more discharge openings into a pressure-medium supply container. The resistance of the piston depends on its speed and the through-passage cross-section which controls the quantity of the pressure medium discharged. The overall through-passage cross-section available for the discharge of pressure medium out of the cylinder becomes smaller as soon as the piston is moved out of its starting position owing to the impact of a load. The fixed discharge-opening arrangement defines successive control range, in each of which there is formed a predetermined resistance profile and a retardation control, related thereto, for a corresponding load or mass. The lightest mass with its highest possible speed within the range defined by the construction achieves its upper retardation limit in the first control range. The heaviest mass with its highest possible speed within the range defined by the construction achieves its upper retardation limit in the last control range. In order to achieve the rest position, all loads in the range defined by the construction are retarded over the entire stroke of the piston.

Title: Device for the transportation and installation of heavy spare wheels
Inventor: WEIHER WALDEMAR
IPC: B62D43/00
Filed: 1981-05-09
Abstract: The object of the invention is to safely transport a spare wheel with the commercial vehicle by means of a device and with the aid of this device to facilitate the changing of the wheel. This problem is solved by the designing of the device as a hook-in wheel basket (1) which can be moved by means of its own wheels (4) or by rollers and the side parts of which comprise fork prongs (3) for receiving the upright wheel according to the barrow principle, a pivotable bar (5) serving either as a basket wall or handle, and a pair of suspension means (2), the hooks (6) of which are hooked onto bar brackets (7) on the commercial vehicle. By virtue of the arrangement of the hooks (6) of the suspension means (2), the wheel basket (1) swings into the horizontal position in order in this position with the now captive wheel to become fixedly connected to the commercial vehicle by means of catches (9), bolts or screws. The transporting, picking up and putting down of the wheel in accordance with the barrow principle facilitates the transportation of the wheel around the commercial vehicle and permits the wheel to be brought in the axial direction against the wheel hub and to be raised up to the axle centre. <IMAGE>

Abstract: During spraying of filter material used in the tobacco-processing industry with a liquid softening agent in an application chamber (18), if conveying is interrupted, at least one of the two components of the softening agent remaining in the application chamber is removed, temporarily stored in a separate reservoir (37) and returned to the application chamber as quickly as possible, in addition to the normal supply of softening agent, when conveying is resumed, in order to ensure in this manner that a quantity of softening agent which is as clearly defined as possible is always applied to the filter material in the start-up phase of the machine as well. <IMAGE>
Patent DE-3123203-A1 (DE)
Title: Sampling-type measuring circuit
Inventor: MENLOVE ROBERT PETER
IPC: G01R19/04
Filed: 1981-06-11
Abstract: A sampling-type measuring circuit is described which provides for extremely accurate amplitude measurements at particular points on a complex wave train containing radio-frequency components. Such measurements are required in connection with television wave train calibration instruments. A sampling circuit having extremely short sampling switching times is used so that an associated storage capacitor is continuously charged in discrete steps until the level of the sampled wave train amplitude is reached. A voltage drop across the storage capacitor is compensated for by feedback devices and, at the same time, changes in the bias characteristics of the sampling circuit are corrected.

Title: Process for reducing the viscosity of chocolate products, couvertures and fatty coatings
Inventor: MOHR HILDEGARD
IPC: A23G1/36
Filed: 1982-03-20
Abstract: Reducing the viscosity of chocolate, couvertures and fatty coatings is an important technical and economic problem. This has been hitherto achieved predominantly by additions of soya lecithin, which, however, beyond a certain level of addition, actually increase the viscosity. The reason for this phenomenon was sought. It is due to the unfavourable mixing ratio of lecithin to cephalins to inosyl phosphatides in soya lecithin. On shifting this ratio to the disadvantage of lecithin and cephalins, even with relatively large additions of "soya lecithin" the viscosity can be considerably reduced.
Patent DE-3214713-A1 (DE)
Inventor: HEGER WERNER ING GRAD
IPC: F04B49/00
Filed: 1982-04-21
Abstract: A valve plate, inserted between the cylinder body and head parts of a compressor, holds the usual compression valve, which opens to connect the compression and pressure chambers during the compression stroke of the piston, and the suction valve which opens to connect the suction and compression chambers during the piston intake stroke. A separate plate-type idle valve also within the plate is positioned to open into a recess of the compression chamber so that there is no interference with the movement of the piston. The idle valve is controlled by an idle piston actuated by pressurized air admitted through a pressure regulator which opens when the reservoir pressure exceeds a predetermined level. Opening the idle valve shifts the compressor operation from compression to idle condition by permitting unhindered passage of air between suction and compression chambers.

Title: Process for the regeneration of metal-laden liquid organic cation exchangers
Inventor: HENG RUDOLF
IPC: C22B3/32
Filed: 1982-05-26
Abstract: Separation of the metal content of the laden organic cation exchanger, with simultaneous regeneration of the cation exchanger, takes place in the regeneration. To obtain the metal content in the form of easily filterable oxides and to obtain the organic phase in reusable form without decomposition, the metal-laden organic cation exchanger is treated with an aqueous solution of an alkane monocarboxylic acid; the resulting organic phase, which consists of the organic cation exchanger in organic solution, is separated from the aqueous phase, which contains the metal in the form of a salt of the carboxylic acid; the metal is split off from the aqueous phase at elevated temperature in the form of metal oxide and the aqueous solution of the carboxylic acid is thereby recovered; the metal oxide is separated from the aqueous solution of the carboxylic acid, and the aqueous solution of the carboxylic acid is returned for treatment of the metal-laden organic cation exchanger.

Title: Engine and accessories, in particular carbon-fuel engine
Inventor: EICKMANN KARL
IPC: F02G1/00
Filed: 1982-09-09
Abstract: The invention relates in particular to measures for making the pressure and the temperature in the external firebox of a combustion chamber, fed by a compressor set, between compressors and expanders so high and at the same time keeping the whole engine or the combustion installation operationally reliable, that solid fuel also, for example in rod form, can be burnt in the high temperature at a given advance speed of the fuel rod. The temperature can be brought so high that the fuel rod being inserted ignites and burns itself. Gas which is too hot after combustion can be cooled economically by water injection and used for work power output. In the implementation of the invention, it emerged that such engines with external fireboxes, as a result of good compressors, valves and the combustion chamber design, can also work as petrol engines with degrees of efficiency which are not inferior to those of existing Otto engines. Fuel powder can also be burnt and the parts, which serve for perfecting the engine, can find further applications in hydraulics and pneumatics, as well as in aeroplane construction and vertical take-off of aerofoil aeroplanes. As the expanders in such engines produce work on every downward stroke, the engines are particularly compact or they produce increased power for their weight and dimensions.
