Title: Hand torch with rechargeable accumulator - incorporates heat sensitive element controlling switch for bulb indicating interruption of mains supply
Inventor: RUNTSCH ERHARD ING GRAD
IPC: F21S8/00
Filed: 1980-04-03
Abstract: The hand torch with a rechargeable accumulator (6) has two plug-in contacts (2) for mains connection, connected by resistances (4) to a rectifier bridge (5) for the accumulator. This is connected by a switch (7) to the bulb (8), with a heat sensitive element (9) and switch contacts (28,29) across it. The element is enclosed by a coiled resistance (10) connected by a heating wire (30) and limiter resistance (31) to the mains connections. As soon as thr torch is disconnected from the mains supply, the heat sensitive element cools and the contacts (28,29) close. The lamp is then operated, indicating that the supply is interrupted. In an alternative design, the torch is clipped across a conductor rail and then indicates if there is a mains supply failure. The torch can easily be removed and fitted with a strap engaging the securing clips, for use as a carrying handle.

Title: Tumble-dry procedure for combined washing and drying machine - interrupts slow drum rotation with short-period fast rotation
Inventor: STRASINSKY DIETER
IPC: D06F58/30
Filed: 1980-05-03
Abstract: A combined washing and tumble-drying machine uses a drying cycle in which the drum revolves at a speed of approx. 50 rpm for 3-10 min., and is then switched to a speed of 200-450 rpm for 5-30 sec., this cycle being repeated throughout the drying phase. The short-period, high-speed rotation may also be performed at least once during the cooling phase, in which the heater is switched off. This procedure increases the evaporation rate of the moisture in the load, giving shorter drying times with increased efficiency of power utilisation.

Patent DE-3028636-A1 (DE)
Inventor: ADAM GERHARD
IPC: B02B1/08
Filed: 1980-07-29
Abstract: The object of the invention is to design the thermal drying more effectively by improving the energy efficiency. The objective of the invention is to design the solution according to the invention in such a way that a plurality of heating, drying, mixing and diffusion sections are assigned to the drying process, in which sections the drying medium and its discharge air are used to contact-heat the cereals. The discharge air is conducted out of the dryer shaft with the aid of the suction of the flow of the drying medium. For this purpose, air guiding roofs (8) which are laid in the treatment element (2) in a grille-like fashion and are closed at the end sides penetrate the air guiding roofs (5) which are offset by an angle of 90 DEG  and open at the end sides. At every point of intersection (10), the air guiding roofs (5) which are open at the end sides are provided with a through-opening. The air guiding roofs (8) which are closed at the end sides are positioned with their roof ridges (9) over the planes (3; 3'; 3'') of the air guiding roofs (5) which are open at the end sides. On both sides of the penetrations, the roof faces of the air guiding roofs (8) which are closed at the end sides are provided with cutouts so that the length of the valley channels is reduced. <IMAGE>

Title: Quenching tank with grid hoist carrying stack of workpieces - where hoist is lowered into tank to form part of closed circuit through which quenching liq. is driven by propeller
Inventor: BAKRAN VELIMIR DIPL ING
IPC: C21D1/64
Filed: 1980-07-30
Abstract: The workpieces are stacked on a grid in a vertical shaft forming a hoist which can be lowered into a tank filled with water, oil, or molten salt.

The result is that the liq. can be driven up the shaft and thus over the surfaces of the workpieces. The propeller is pref. located inside a duct with bent inlet and outlet ducts so the liq. flows through a closed circuit. Uniform hardening is obtd. without uncontrolled and varying distortion of the workpieces.

Title: Yarn feed changeover mechanism for circular knitting machine - having parking position upstream of feed point for feeder crossover
IPC: D04B15/58
Filed: 1980-09-03
Abstract: A multiple yarn feeding device for double-cylinder knitting machines has from five to seven yarn guide arms each holding a different yarn, which can execute a swivelling motion from a rest position, through the feed position, to a parking position sufficiently far upstream of the feed position to clear the latch guard and the sinkers, to allow a cross-over of the guide-arm of the incoming yarn with that of the outgoing yarn. The feeder arms are moved by cams operating on rockers, and controlled by slots in a guide plate, such that the parking position is attained whilst the rocker is still on the rising of the cam. The superfluous motion of the rocker is absorbed by a spring, ensuring that the feeder arm is held firmly in the parking position, and its motion is strongly damped. This construction is simpler and more versatile than previous designs. It is less critical in its setting and allows the number of feeder arms to be increased.

Title: Process for the treatment and distribution of solid, pulverulent and granulated material in agriculture
IPC: A01C23/00
Filed: 1981-04-03
Abstract: The process is based on a qualitative and odourless elimination of aggressive and strong-smelling waste materials of solid, pasty, pulverulent and granulated quality. The waste materials relevant here are introduced into an open pressureless container and are variably treated and compacted uniformly there at the container outlet, so that there are no longer any voids in the material. The material thus compacted, after coming out, is broken up into very fine particles as a result of rotation and is distributed in an environmentally friendly and exactly metered manner over broad areas. A tanker (5) serves for the transport, compaction and distribution of the material. A conveyor worm (2) is arranged in the container (1) at the bottom in such a way that the worm shaft (10) is connected to the gear (20) on the driving side. On the opposite side, the worm shaft (10) is seated in the bearing (12) which at the cover end (13), and there at the channel (29), the latter being fastened to the tank (1), constitutes the pressure zone (30). By means of a slide (3), the material is compacted and is finely comminuted and distributed in an exactly metered manner by the rotating plate discs (4) fitted with cutting knives (37). The drive takes place via a power take-off shaft (39) to the gear (20) and from there directly to the worm (2) and via a power take-off shaft (37) which is provided correspondingly to the gear (35) of the plate discs (4). <IMAGE>
