Patent DE-3214943-A1 (DE)
Title: Vibrator screen
Inventor: UTSITEL ALEKSANDR D
IPC: B07B1/36
Filed: 1982-04-22
Abstract: In a vibrator screen, the oscillator exciter (5) in the form of a shaft (7) with an unbalanced weight (6) is arranged in the region of one of the oscillation centre points (C1, C2). The shaft (7) of the oscillation exciter is oriented along the elongate screen casing (2). The unbalanced weight (6) is arranged longitudinally adjustably with respect to the shaft (7) of the oscillation exciter (5). By producing the uneven vibration field transversely with respect to the screening surface an intensive loosening of the layer of the material for screening is ensured even when its moisture content is relatively high. As a result, a high degree of efficiency in separating the material is ensured. <IMAGE>

Patent DE-3229041-A1 (DE)
Inventor: COENEN HUBERT DR-ING ANTRAG AU
IPC: A23J7/00
Filed: 1982-08-04
Abstract: A process for the recovery of lecithin from mucilaginous substances obtained in the production of vegetable fats and oils by extraction with a solvent which is gaseous under normal conditions. The mucilaginous substances are extracted at a pressure from 2xpk to 500 bar and at a temperature from 0 DEG  C. to <Tk for a period from 15 to 60 minutes to form a charged compressed solvent phase containing extracted substances and an extraction residue containing insoluble lecithin. Then, the charged, compressed solvent phase is separated from the insoluble lecithin. Thereafter the extracted substances are separated from the charged, compressed solvent phase and the gaseous solvent is returned to the extraction stage. The lecithin is removed from the extraction stage and is obtained in solid form by evaporating the solvent.

Title: Electric motor-driven knife
Inventor: KRAH KLAUS
IPC: H01H3/20
Filed: 1982-09-02
Abstract: Electric motor-driven knife, in particular for cutting foodstuffs, having a housing which possesses a handle and is intended for accommodating the drive motor and holding devices for at least one knife blade, and having a switching member for opening and closing the circuit for the drive motor. To prevent unintentional actuation of the switching member, the latter is assigned a blocking member in such a way that the switching member can be actuated only after the blocking member has been conveyed into its inoperative position. The actuation both of the blocking member and of the switching member takes place with tensioning of a spring in each case. This spring tension is used to return the switching member and the blocking member to their rest position, in which the switching member is secured again.

Patent DE-3312296-A1 (DE)
Title: Vibration-damping swivel joint, in particular for motor vehicles
Inventor: SCHMID LEOPOLD F
IPC: F16D3/205
Filed: 1983-04-05
Abstract: Critical vibrations may occur in the drive train for the wheels of a motor vehicle and these cause such severe drumming noises that vibration absorbers have to be used. Since vibration absorbers are expensive, heavy and take up a lot of space, the invention proposes a vibration-damping swivel joint in which the driving half of the joint is rotated relative to the driven half of the joint against the resistance of springs, stops limiting the relative rotation of the two halves in such a way that the maximum spring torque produced by all the springs together is smaller than the maximum operating torque of the swivel joint.

Title: Two-stage coal hydrogenation process with a first catalytic stage and increased yields of distillation liquids
Inventor: HUIBERS DERK T A
IPC: C10G1/00
Filed: 1983-08-10
Abstract: In a process for the two-stage hydrogenation of coal to produce liquid and gaseous hydrocarbon products in increased yields, the particulate coal is fed at a temperature below about 340 DEG C (650 DEG F) to a reaction zone of a first stage in order to maintain therein a temperature of 400 to 430 DEG C (750-800 DEG F) and a hydrogen partial pressure of 70 to 350 bar (1000-5000 psig). The partially hydrogenated material from the reaction stage of the first stage is phase-separated, and the liquid fraction is passed to the reaction zone of the second stage, which is held at a temperature of 430 to 460 DEG C (800-860 DEG F), for further, predominantly thermal hydrocracking reactions. In this process, the coal charge is rapidly heated and then catalytically hydrogenated and hydrocracked under selected conditions which result in minimum production of undesired residue and unconverted coal or coke and in increased yields of desired hydrocarbon liquid products, while the catalyst life is increased.

Abstract: The invention relates to a rotary slide valve, the cylindrical valve member of which is mounted with its axis of rotation transverse to the flow and rests within a fixed coaxial cylinder of approximately the same size, of which the orifices allowing the flow medium to pass through are controlled by orifices and wall parts of the valve member. The valve member is surrounded coaxially by an outer cylinder which has a larger diameter and which possesses on each of its sides located opposite one another respectively an inlet and an outlet and first and second conduits, so that, in the normal position of the valve member, the inlet on the one side is connected to the second conduit on the other side and the outlet on the one side is connected to the first conduit on the other side and, in the deflected position, the inlet and first conduit are connected to one another and the outlet and second conduit are connected to one another. In the latter position, a first stream flows through a first inner chamber of the valve member, and a second stream flows through a pair of second inner chambers of the valve member, which flanks the first chamber in the axial direction and a partition wall formed in an axial plane in the first chamber. The valve member does not touch the outer cylinder, and in the rotary positions the streams flow through the inner spaces of the slide valve.

The shank of the attachment element 1 consists of two shank parts 9', 9", which enclose a cavity and are separated from one another, and whose mutually facing edges 1 are spaced apart from one another by means of release grooves 11. A shank 4 of the locking part 2 has different dimensions in different radial directions, mutually opposite edges 26 of this shank 4, which is inserted into the cavity, engaging into the release grooves 11 (said edges 26 being separated from one another as a result of the larger dimension) when the locking element 2 is rotated into a predetermined first position with respect to the attachment element 1, in which first position the shank parts 9', 9" are not expanded. The shank 4 of the locking element 2 has the smaller dimension in a second direction, so that it does not engage into the release grooves when the shank halves 9', 9" are expanded (second position). In the first position, the shank 4 of the locking element is fixed against axial displacement with respect to the attachment element 1 by means of shoulders 44 of the shank 4 of the locking element 1, which engage over the upper ends 45 of the release grooves 11. <IMAGE>
