Title: Dispenser for liquid body-care substances
IPC: A47K5/12
Filed: 1981-08-26
Abstract: The invention relates to a dispenser for liquid body-care substances, for example liquid soap, shampoos or the like. The dispenser has a container with a lid on which a pump is fixed. The pump has a suction pipe which is immersed in the container and two non-return valves which are arranged one after the other in said tube, which open in the suction direction, and between which is arranged a compression spring supported on the two valves. The upper non-return valve is axially displaceable via an actuating element and is connected to an outlet pipe. In order to obtain a design which is simple in terms of production and a pump which is easy to service in use, according to the invention the lower non-return valve is inserted in the suction pipe with a circumferential seal and is braced between a stop in the suction pipe and the compression spring. By this design of the lower non-return valve, the assembly - as well as disassembly for cleaning purposes - is very simple. Only the lower non-return valve, the compression spring and the upper non-return valve with the actuating element need to be inserted one after the other, the compression spring and the stop ensuring a secure fastening of the lower non-return valve.

Title: Injection-moulding machine serving for the production of technical mouldings in particular
Inventor: MAIK WALDEMAR
IPC: B29C45/27
Filed: 1981-11-16
Abstract: In the case of an injection-moulding machine equipped with a fixed platen and a movable platen, an injection unit and a removing device for the sprue which is formed, the sprue formed in the sprue bush, connected to the fixed half and having a conically tapering runner, is drawn out from the runner by the injection nozzle when the latter is retracted and is separated from the moulding located in the closed mould, since the head of the injection nozzle partially entering the runner cuts off behind the sprue. The sprue-removing device is fastened on the fixed platen and is controlled by the relative movement of the injection nozzle with respect to the fixed platen and strips the sprue off the injection nozzle by a reciprocating movement. The time at which the sprue is removed from the injection nozzle can be determined optimally by means of a time-lag relay, without increasing the cycle time of the machine. <IMAGE>

Title: Process and equipment for the thermal treatment of granular materials
Inventor: KRUEGER HOLM
IPC: B22F1/142
Filed: 1982-07-26
Abstract: In the thermal treatment of granular materials, in particular for hardening or tempering blasting agent particles in a furnace by means of hot gases, optimised heat transfer from the fuel gases to the granular materials is difficult to control and involves a high energy consumption. In order to achieve optimised heat transfer and heating of the granular materials by means of hot fuel gases with low energy consumption and good controllability, the granular materials are therefore, according to the invention, separated into grain fractions and passed downwards in a shaft furnace on approximately meandering paths under control essentially in countercurrent to the fuel gases.

Title: Method for correcting raster distortions
Inventor: SIEGEL EMIL
IPC: H04N3/233
Filed: 1982-11-29
Abstract: A method for correcting raster distortions is proposed as a result of which it is possible to adjust and to correct any side of the television image independently and without influencing the other side. For this purpose, half-sawtooth signals (b to e) are derived from the H and V sawtooth signals (a), the positive (b, e) and negative (c, d) parts of which can be adjusted depending on the raster distortion. The signals (f, g) thus generated are multiplied by sawtooth-shaped or parabolic signals of the other deflection direction in each case, and the correction signals (i) thus obtained are mixed in with the deflection signals to result in raster correction. <IMAGE>

Patent DE-3317747-A1 (DE)
Title: Sealing housing for guiding an incremental displacement sensor system
Inventor: MAUSS ULRICH
IPC: G01B3/00
Filed: 1983-05-16
Abstract: In order to prevent suppression of pulses due to ingress of dust or liquid into the housing used to accommodate an incremental measuring system, said housing is sealed in such a way that it is itself suitable for measurement operation when entirely bathed in liquid. The basic idea of the sealing consists in displacing the internal rotor, supporting the scanning device, via a steel wire which transmits with little tensile strength the displacements covered in each case by the external rotor. The pulse counting thereby produced in the opposite direction is balanced by polarity reversal. The system sealing is thus limited to sealing the steel wire opening, and is achieved via piston rod sealing sleeves in the covers closing the housing. <IMAGE>
Patent DE-3318351-A1 (DE)
Title: Method for an evaluation circuit, dependent on the speed and direction of rotation, of an incremental pulse generator for the direction of rotation
Inventor: BONSS RAINER DIPL ING
IPC: G01P13/04
Filed: 1983-05-20
Abstract: This generator generates two mutually phase-shifted pulse trains whose pulse information is stored in a reference memory. In order, despite contact bouncing of the generator, to facilitate reliable and, depending on the rotational speed of the generator with regard to the acceleration, progressive forwards or backwards recognition, it is proposed to use a reference bit pattern generator which calculates two individual bits from a reference word, one individual bit representing the bit next expected for right-hand rotation and the other individual bit representing the bit next expected for left-hand rotation. One individual bit each and one reference bit each are compared with the two bits transmitted by the generator after a pulse change, in the event of equality a pulse, which is stored in a buffer, being generated for right-hand rotation or for left-hand rotation. The right-hand/left-hand pulse effects addition or subtraction in an arithmetic unit, the result of which is stored and displayed. The rate of addition or subtraction is influenced by a progression circuit.
