Title: Metal layer margin removal - from insulating foil strip by d.c. arcs across edges
Inventor: PETRICK PAUL DR
IPC: H01G13/06
Filed: 1979-11-09
Abstract: The margins of a metal layer are removed from the edges of an insulating foil strip in the manufacture of wound capacitors by drawing the strip with the insulating side down over a roll which extends beyond the edges and is held at a negative d.c. potential relative to the metal layer. The insulating strip is a thick plastic foil with metal (Al) coating. The voltage is high enough to produce an arc across the foil edge and to remove the metal along the margin. The arc is stabilised by needle electrodes, kept at a negative potential to ionise the air around the arc. This creates a more reliable and economical method than grinding or spark erosion.

Patent DE-3103087-A1 (DE)
Title: Roller guide in a continuous casting installation for slabs
Inventor: EBERL MARTIN
IPC: B22D11/128
Filed: 1981-01-30
Abstract: The spindle bracket, shown in Fig. 5, for strand guiding rollers is installed as a supporting mount under strand guiding rollers of continuous casting machines so that, with as small as possible diameters of the guiding rollers, a correspondingly small roller pitch is achieved. These supporting mounts prevent deflection of the guiding rollers. By means of this design incorporating small roller diameters and supporting mounts, it is possible to install approximately twice the number of guiding rollers, making possible a better continuously cast product since the camber of the continuously cast product between the guiding rollers is only half as great as with conventional guiding-roller spacings. Internal deformations in the continuously cast product are thereby reduced. <IMAGE>

Patent DE-3124390-A1 (DE)
Title: Phase-compensation gear for the shedding device of Jacquard machines
Inventor: KEIM WALTER
IPC: D03C3/28
Filed: 1981-06-22
Abstract: The invention relates to a phase-compensation gear for Jacquard machines, by means of which, in the event of the machine return, the phase shift, arranged for the forward run, between the curves of movement of the lifting knives and the sinker press-down device is to be reversed in an accurate and reproducible manner. For this purpose, the invention provides a multi-stage planetary gear, especially a planet-wheel gear (5), between the machine drive shaft and the sinker press-down device, the output shaft (2) of which planetary gear is temporarily uncoupled from the machine drive shaft for the reversal of the phase shift. The normally retained outer central wheel (9) is then released and is rotated into a second retaining position by the driven planet-wheel carrier (6) which now rolls on the stationary inner central wheel (10) of the output shaft (2). The retention takes place by means of stop noses (15, 16) which engage alternately into one of the notches (13, 14) on the outer central wheel (9). The stop noses (15, 16) are mounted pivotably and are brought into and out of engagement as a result of the rotation of a switching lever (18) provided with a limited switching curve (21). The switching lever (18) is connected to the output shaft (2) via a free-wheel, on which it is fastened by means of a clamping arrangement (20) designed as a slip coupling, the connection being fixed in terms of rotation through the return run. <IMAGE>

Title: Four-chamber four-stroke oscillating piston engine
Inventor: TWACHTMANN FRIEDRICH
IPC: F02B53/00
Filed: 1981-07-11
Abstract: The engine represents a simplification of a conventional four- cylinder four-stroke piston engine. The working processes occur in four chambers rather than in cylinders, thereby saving space and materials. The engine housing comprises an annular, space-enclosing centre piece and two connecting side wall pieces. Swivellably mounted on a journal a hollow shaft lies at the middle of the engine, which shaft has two symmetrically similar oscillating cranks lying opposite one another, which slidably extend up to the inner wall side of the centre piece, dividing the space, cf enclosed drawing 6. The centre piece has two opposing, symmetrically similar webs, which slidably extend up to the shaft. Four sector-shaped chambers are then produced, the volume of which varies as the shaft together with its oscillating cranks oscillates to and fro. Two valves built into the web area are assigned to each chamber. In addition, two camshafts together with rocker levers are provided. The chambers are sealed off by means of sealing strips. The force is converted into a rotary movement on the outer wall side by way of a toothed segmental piece fitted on one main journal end by means of a rack-toothed connecting rod capable of simultaneously moving up and down and oscillating in a circle. <IMAGE>
Patent DE-3130578-A1 (DE)
Title: Waste collection container
Inventor: BAURENSCHMIDT HEINZ
IPC: B65F1/02
Filed: 1981-08-01
Abstract: A stackable waste collection container (1, 2) has an upper covering wall (9, 10) whose surface at least partly covers the bottom surface (19, 20) projected onto the covering wall. At least one filling aperture (15, 16) is arranged to the side of the covered area. Such a waste collection container (1, 2) can be erected, stacked if appropriate, close to a household in a similar manner to a conventional refuse bin or a conventional refuse container, and is used for the selective deposition of the various wastes produced, such as waste paper, glass, etc., so that the wastes can be sent for treatment and reused. By means of the erection close to a household of a relatively large number of such waste containers (1, 2), the latter are on the one hand within easy reach for the dumping of the waste; they also have comparatively low volume and hence small external dimensions, so that the collection and emptying of the containers can be efficiently carried out with suitable vehicles. Depending on the circumstances in the individual case, and possibly also in accordance with the type of waste, either a collection vehicle can take the containers away and empty them directly or it can transport the containers, also stacked if appropriate, to a central discharge point. As a result of an attractive appearance of the containers, with an upper cover for rain protection and for storage in the stack, the erection of a number of containers close to a household gives rise to no unwelcome effects as a result of unaesthetic appearance, danger of injury, odour nuisance, etc. <IMAGE>
