Title: Linear motor double stator length - has main and regulator exciter windings fed by gap dependant adjuster
Inventor: WEH HERBERT PROF DR ING
IPC: H02K41/03
Filed: 1974-10-18
Abstract: The distance between the stator halves is decreased by the current conducting centre section of the transistor being made broader than the stator plates. The exciter windings are divided into a main winding receiving a constant current and a regulator winding fed with a variable current by a gap dependent adjuster. The main and regulator parts are not coupled inductively.

(I) is pref. a fusible chloroparaffin or a mixt. of liquid and solid chloroparaffins. The mechanical props. of the prod. can be modified by the incorporation of polymeric additiveis such as PVC, vinyl chloridevinyl acetate copolymer or EVA. Storage stabilisers such as Pb-, Ba or Cd salts sol. in (I) may also be added. (II) may be Al powder and (III) is e.g. ZnO. Generally the components are mixed together in the melt, cast into shapes or into metal containers, and allowed to cool and set.

Title: Use of slag granulate as shot blast medium - granulate is moved in fluid stream after drying and sieving
Inventor: EHLERT JOACHIM DIPL ING
IPC: B24C11/00
Filed: 1974-11-11
Abstract: Use of molten ash chamber slag granulate as a shot blast medium for cleaning metal surfaces where it has been found that it is not necessary to completely eliminate the internal stresses in the granulate. It is only necessary to move the granulate in a fluid stream through different specific weight of granulate and feed medium, a turbulent flow is produced and the granulates rub against each other. The production of different grain fractions can result after the drying by simple sieving. Specifically, the granules have a grain size of 0.5m to 2mm, preferably 0.5 to 1 mm.

Patent DE-2529260-A1 (DE)
Inventor: STEHMANN HANS-PETER
IPC: B29C48/06
Filed: 1975-07-01
Abstract: The base material, for example polyethylene, is mechanically worked in the presence of the silane compound and of the additives. To prevent blistering and in order that the end product may be suitable for insulations for higher voltages, for example 10 kV or higher, the additive-admixed and worked, silane-grafted base material is continuously devolatilised (degassed) while still hot as a continuous stream of material as it is being extruded. The apparatus consists of an L-formation of two extruders (3, 9). The first extruder (3) receives the base material and the additives and is where the preparation and grafting take place. The second extruder (9), which is mechanically firmly connected to the first extruder (3), devolatilises the supplied grafted material and homogenises it further and extrudes it. <IMAGE>

Title: Electronic distance measuring instrument - operates with ultrasonic waves by signal reflection method
Inventor: WIESBECK WERNER DR ING
IPC: G01S15/14
Filed: 1975-07-16
Abstract: The distance measuring system is applicable in the centimetre, and metre range, e.g. for filling level measurement or conveyor belt control, or for coupling and parking manoeuvres of vehicles. Ultrasonic pulse trains are periodically transmitted, consisting of several individual pulses of repetition frequency f1 in the ultrasonic frequency range.

A typical circuit arrangement involves two digital oscillators (1), (2) with inputs to an AND gate (3) the output of which leads to an ultra sonic generator (4) at f1. The receiver (5) at f2 feeds a threshold amplifier (6), another AND gate (7) monoflop (9) and loudspeaker (10).
Patent DE-2532884-A1 (DE)
Title: Fluid flow switching and regulation - using multiple function valves to reduce component useage and widen facilities
Inventor: BLANK KARL-HEINZ
IPC: G05D7/03
Filed: 1975-07-23
Abstract: An arrangement for control and constant flow regulation of a volumetric flow is designed to reduce component useage and thus increase system efficiency by using multiple function valves. A single valve performs both the function of a fluid switch and of a flow regulating valve, and can be switched between the two states. A pump supplies fluid to operate an actuator under control of the double function valve which controls both the fluid flow and its magnitude. The second valve controls the pressure difference across the first valve and hence the flow through it by operating as a piston manometer. Both valves can operate additionally to prevent flow and as pressure release valves. Excess fluid is returned to the reservoir.

Title: Paper bale binding electrical cutter - melts metal binding locally between double contacting rollers and has sprinklers to protect bales
Inventor: WAENERLUND LARS
IPC: B65B69/00
Filed: 1975-12-17
Abstract: Paper pulp bale binding is fusion released electrically, across pairs of electrodes. Conveyed banded bales traverse a turntable. Current across articulated twin-disc contacts melts the metal binding, obviating manhandling and hand tool cutting of recalcitrant tight binding. Water sprinkling prevents pulp burning and discolouration. A turntable (3) between the conveyors (14,15) receives a tied (6) bale (2). Sideways swinging arms (7,9) carry electrified roller discs (10), pressing on one or both sides of the spike (17) held bale, at two different heights for assured severance. Feed, holding, table rotation and the pressure exerted by the electrodes are automatically controlled.

IPC: D06F57/12
Filed: 1976-01-24
Abstract: A clothes drier that can be fixed to a wall has two load-bearing arms which open and close in the manner of the leaves of a door, and several parallel, superposed, rods for hanging-up the clothes to be dried which are slidingly guided along the arms in such a way that they are arranged parallel and spaced one behind the other when the arms are swung open. Each hanging-up rod slides in a hole of a load-bearing arm. The holes are arranged one above the next, in staggered relationship. Each arm has depressions in which the rods rest when the appliance is in the "closed" position. The article as claimed, does not take up much space when closed, yet opens out sufficiently wide to afford a relatively large drying space when the clothes to be dried are hung upon it. Simple construction enables it to be made from a relatively few components.
