Abstract: A control valve (1) for hydraulic media has a valve housing (2) with a pressure connection (P), a consumer connection (A/B) and a tank return connection (T). A valve arrangement consisting of two sectional valves (84, 120) is arranged inside the valve housing (2) in such a way as to be axially displaceable by means of a lever (8) between an initial position and an operating position. In the initial position, the consumer connection (A/B) is connected to the return connection (T) via the opened first sectional valve (84) and the pressure connection (P) is closed via the second sectional valve (120). In the operating position, the consumer connection (A/B) is connected to the pressure connection (P) via the opened second sectional valve (120) and the return connection (T) is closed via the first sectional valve (84). According to the invention, the valve arrangement includes a first, top plunger (10) and a second, bottom plunger (12) which are displaceably guided axially one behind the other in alignment in the valve housing (2) relative to one another and relative to allocated passages corresponding to the connections (P, A/B, T) in such a way that a change-over between the initial position and the operating position is effected with positive overlap. <IMAGE>
Patent DE-3731917-A1 (DE)
Inventor: WALLACE-SIMS GRAHAM ROBIN
IPC: G08B13/196
Filed: 1987-09-23
Abstract: A signal is generated for producing a video display of superimposed images, one of which is derived from a system for detection of non-visual signals, such as an ultrasonic inspection system 12, 13 whilst the other is a television image produced by video camera 16. Accurate registration of the superimposed images is achieved by providing a movable probe 13 of the ultrasonic inspection system indicating the location of inspection with a point source 15 of light or other radiation to which the video camera responds. During each raster scan of the video camera the position of the point source is registered and data, representing the response of the detector system, stored in a memory system. An output from the memory system is combined 22 with the camera video signal to produce the superimposed images. When the probe indicates that test piece 11 is O.K, only switch 24 is closed giving a green image, but at points where the test piece is defective only switch 23 is closed giving a red image (as opposed to a black and white image for untested area). <IMAGE>

Patent DE-3801327-A1 (DE)
Title: Load-relief network for branch pairs, which are free of off-state voltage, of a multiphase converter
Inventor: LANGER JOHANNES GEORG DIPL ING
IPC: H02M7/521
Filed: 1988-01-19
Abstract: Electronic power circuits using GTO thyristors (T1...T6) or transistors as controllable electronic switches require a load-relief network for operation, which network delays the current rise during switching on and the voltage rise during switching off. In detail, a switching-off load-relief capacitor (CEA, CEB, CEC) and two switching-off load-relief diodes (D1...D6) are provided per branch pair, as well as a load-relief resistor (RO) or DC/DC voltage converter (4) which is common to all branch pairs (1, 2, 3). In order reliably to prevent dangerous voltage spikes when switching the GTO thyristors off, it is proposed to provide a dedicated storage capacitor (CPA, CPB, CPC) per branch pair and to arrange one decoupling diode (DA, DB, DC) in each case between the load-relief resistor (RO) and the individual storage capacitors. As an alternative to this, the DC/DC voltage converter (4) can also be constructed as a voltage-stabilising energy recovery transformer (feedback transformer). <IMAGE>

Title: Driver for connecting one end of a scraper device to a round-steel chain of a double-chain scraper conveyor
Inventor: MARKUS EUGEN
IPC: B65G19/10
Filed: 1988-08-24
Abstract: Only drivers having two projections which are arranged in a fork-like manner and can be inserted and pivoted in the free interior space of vertical chain links can be installed in tensioned round-steel chains driven via chain wheels. Drivers for round-steel chains driven via trough wheels can only be mounted when the chain is untensioned. The novel driver is to be suitable for tensioned round-steel chains and those guided via trough wheels. The two projections (9, 10) arranged in a fork-like manner engage around a horizontally pivotable vertical chain link (2a), have in each case one recess (11, 13) and engage in a fork-like manner around a chain link (2b, 2c) leading or running behind the vertical chain link, the recesses (11, 13) permitting vertical movement of the horizontal chain links (2b, 2c) about a horizontal articulation axis (a, b) and the recess (11), in the case of the leading projection (9), making possible horizontal swivelling from the tensioned round-steel chain. The main field of application is a double-chain scraper conveyor having round-steel chains driven via trough wheels. <IMAGE>

Title: DC voltage supply having stepped fast interruption
Inventor: MAXAM SIEGFRIED ING GRAD
IPC: G05F1/62
Filed: 1988-08-29
Abstract: If parasitic discharges occur in a discharge PVD coating system, then it is necessary, in order to avoid damage to the workpieces, to interrupt the current, which is then sharply rising, withing microseconds. When switching back on, and equally steep voltage rise is desired, in order to achieve the optimal process parameters immediately again. For this and for other purposes, a DC voltage supply is proposed which consists of individual, series connected stages 1 to 8, each of which outputs only a limited voltage which can be regulated and controlled without the use of special components. This voltage is switched off if the current intensity exceeds a predetermined maximum value and/or if an excessivly steep current rise occurs within the time step. After a predetermined time interval has elapsed, which leads, for example, to the extinguishing of an undesired discharge (are), the stage is automatically switched back on. <IMAGE>

Patent DE-3836726-A1 (DE)
Title: Process for the effective compounding of plasticised PVC mixtures
Inventor: MARTIN HELMUT DIPL ING
IPC: C08J3/18
Filed: 1988-10-28
Abstract: The invention relates to the compounding of plasticised PVC mixtures in high-speed mixing machines. The essence of the invention is to make compounding more effective and to increase the output rate of the mixing machines while minimising the energy requirement. According to the invention, PVC is introduced into the mixing machine at room temperatures. The plasticiser is heated in a separate vessel to temperatures above the optimum plasticiser absorption temperature, is kept in the temperature range in a constant temperature container and is then fed to the mixing machine as and when required. The cold PVC absorbs the hot plasticiser immediately and forms a pourable plasticised PVC mix. Diagram 1 shows how the mixing time lessens as a function of the increasing plasticiser temperature.

Title: Variable-displacement pump for a plurality of consumers which can be actuated independently of one another
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F15B11/16
Filed: 1988-12-30
Abstract: In a hydraulic system with a variable-displacement pump for supplying a plurality of hydraulic consumers, a limit-load control is effected if the load-carrying consumer continues to signal a delivery-flow demand at maximum delivery-flow rate of the pump. To this end, the control pressure introduced in a controlled manner by the delivery-flow control valve in the hydraulic adjusting device of the pump is picked up. If this control pressure drops below a predetermined magnitude, measures for changing the flow through the consumers are initiated, e.g. the flow through all consumers is proportionally reduced.

Title: Oxygen absorbent and use of the same
IPC: A23L3/34
Filed: 1989-02-01
Abstract: The present invention relates to an oxygen absorbent and use of the same. In the prior art, there have always been problems in retaining the freshness of packaged foods and protecting medicaments against oxidation. The invention provides a remedy by creating an oxygen absorbent, more precisely based on a combination of an absorbent in the form of porous precipitated silica as water carrier characterised by a mixture in which the organic substances are formed by glucose and glucose oxidase and the interstitial spaces between the particles and between the pores of the precipitated silica and other solids are kept at least partially anhydrous. To achieve a flowable mixture it is expedient if at least 40% of the interstitial spaces between the particles and between the pores are kept anhydrous, this value being able to be considered as a guide value. At the same time, calcium carbonate, calcium hydrogen phosphate or magnesium carbonate or disodium dihydrogen carbonate are used as absorbent or reaction accelerator. In addition, the invention makes possible the use of a bag or a tablet or pellets and mini containers containing an oxygen absorbent according to one or more of the preceding claims for retaining the freshness of foods.
