Patent DE-3138866-A1 (DE)
Title: Process for producing finished mouldings with regions of different cross-section, in particular chamber and membrane filter plates for solid-liquid separation
Inventor: JUNKER WERNER
IPC: B01D25/21
Filed: 1981-09-30
Abstract: The invention relates to a process for producing finished mouldings with regions of different cross-section from thermoplastic materials, in particular chamber and membrane filter plates for solid-liquid separation, in a heatable compression mould comprising an upper part and a lower part. The invention is characterised in that first of all a plate-shaped preform, adapted approximately to the relative cross-section and volume dimensions of the finished moulding is laid in the compression mould. Then, during closing of the compression mould, the regions of the preform initially bearing against the compression mould are superficially melted. The material thus melted is displaced by the final closing of the compression mould into the still existing cavities of the compression mould.

Title: Process for the preparation of methanol and/or formaldehyde by partial oxidation of methane
Inventor: HUPPMANN GERHARD DIPL PHYS
IPC: C07C45/33
Filed: 1981-10-02
Abstract: For preparing methanol and/or formaldehyde, methane is partially oxidised in the combustion chamber of a periodically operating piston-type machine. The expansion stroke of the piston-type machine cools the reacted mixture adiabatically. This makes it possible to maintain the reaction time very accurately at about 10<-3> seconds, resulting in a high methane conversion.

Title: Road train
Inventor: STRIFLER PAUL DR
IPC: B62D13/02
Filed: 1981-11-05
Abstract: In a road train consisting of a power unit and a trailer, the trailer draw bar, coupled to the power unit, of a trailer steering axle is supported in the region in front of the trailer coupling at the side by in each case at least one energy accumulator with progressive characteristic. When going round a bend, one of these energy accumulators accordingly exerts a continuously increasing restoring moment on the swivelling draw bar in the opposing direction, so that the jack knife angle between power unit and trailer is reduced to a maximum of 10 DEG  and the relative movements, reduced in this way, between the two trailer train units permit vehicle a corresponding increase in the length of the loading surface.

Title: Hose pump for liquids
Inventor: RIX ALBERT
IPC: F04B43/12
Filed: 1981-12-09
Abstract: Hose pumps have proved very successful for the delivery of small, metered quantities of liquid, especially for the delivery of ink in ink jet printers, a driven smoothing roller rolling on a part of a feed hose in the required direction for delivery of liquid. The smoothing roller for this purpose can be driven by a motor via a gear mechanism. The object of the invention is to create a hose pump having a low overall height and functioning with little noise. According to the invention the smoothing roller (25) performs a reciprocating movement in such a way that it describes differing path curves on the forward and return stroke. In so doing the smoothing roller (25) during the forward stroke is in pressure contact with the delivery hose, whereas at the reversal point it lifts off from this and on the return stroke does not exert any pressure on the liquid, for example on the ink in the delivery hose. The smoothing roller (25) is advantageously pivotally mounted on a swivel lever (21). <IMAGE>

Patent DE-3210736-A1 (DE)
Title: Double-disc slide valve control for internal combustion engines
Inventor: WASSERMANN ULRICH
IPC: F01L7/06
Filed: 1982-03-24
Abstract: In the case of the double-disc slide valve constructions described in the references, heavy pressure losses occur in the charge cycle of the engine. These losses largely occur due to marked deflection of the exhaust gases as they flow out of the cylinder into the exhaust port, and/or due to swirling of the fresh gases in the cylinder in the intake process. The slide valve control according to the invention reduces the pressure losses described in that the gas ports are not arranged vertically but inclined in various directions to the slide valves. The exhaust port is adjusted to the direction of the exhaust gas flowing out of the cylinder at an angle to the control slide valve and thereby reduces the flow resistance of the exhaust line. The inlet port is so arranged that the fresh gases flowing into the cylinder are less strongly deflected than hitherto and a desired gas movement occurs in the cylinder. <IMAGE>

Title: Nozzle for spraying particularly air and a spray medium
Inventor: MARSCHALEK ROLAND
IPC: B05B15/654
Filed: 1982-05-12
Abstract: The nozzle (6) for spraying two media, particularly air and a spray medium, by the external mixing principle is sealed by sealing rings (15 and 16) with respect to its mounting (1) or its two parts, namely the bushing (2) on the one hand and the base body (3) on the other hand. These two sealing rings at the same time also form mounting elements for the nozzle (6). A feature of this sealing is that the interior sealing ring (15) not only seals the medium with respect to the nozzle on the one hand and the mounting on the other hand, but also seals one medium with respect to the other. The nozzle (6) is suitable for pairwise fitting in a mounting (1) or else for serial arrangement in a strip-shaped base body. Notwithstanding the rotatable gimbal mounting of the nozzle (6), the two media can be fed separately, with faultless sealing, to in front of the nozzle or into a mixing chamber (17) of the nozzle (6). <IMAGE>

Title: Distillation and sublimation device having a condenser
Inventor: WANETZKY ERWIN DIPL ING
IPC: B01D7/00
Filed: 1982-10-23
Abstract: A distillation and sublimation device has one pressure container and a plurality of containers for the starting material. The containers each have one tray, an external frame and an internal frame having a vapour channel and are mounted one above the other in such a manner that the vapour channels line up. An annular space is present externally to the container stack. The device has a condenser, into which opens the vapour channel of the lowest container. To achieve the aim of preventing vapour condensation on the pressure container, according to the invention it is proposed that open capillary gaps (28) are provided between the containers (26) in the direction of the pressure container (3). Additionally, the condenser (8) is connected to the annular space (10) via at least one back-flow opening (19) for gases. The arrangement is thus such that the annular space (10), the capillary gaps (28), the vapour channels (26), the condenser (8) and the at least one back-flow opening (19) are parts of a closed gas circuit. <IMAGE>

Title: Screen-cleaning device
Inventor: GREINER OTTO
IPC: E02B8/02
Filed: 1982-11-27
Abstract: In a cleaning device arranged on the inflow side in front of a screen of a channel, one rotating chain each is run at the lateral screen edges over a top guide wheel and a bottom guide wheel arranged at the channel bottom. A cleaning rake running upwards along the screen is fastened between these chains. In order to increase the cleaning capacity of the device at the same motor output, a second rake offset relative to the first cleaning rake by half the chain length is attached to the chains. Arranged centrally between the two guide wheels of each chain is a further guide wheel which sits at a distance on the inflow side in front of the common central axial plane of the other wheels. Blocking of the device by bulky floating material, carried along by the active rake, when passing the other rake is thereby avoided.
