Title: Automatic accurate tobacco weigher - prevents over-weighing by separating coarse and fine tobacco particles and by adding fine particles to approach wt. from below
Inventor: GLOCKER HEINZ WALTER
IPC: G01G17/02
Filed: 1978-09-28
Abstract: The tobacco passes from a supply container along an inclined vibrating channel (5). The coarser tobacco particles pass via a grille (50) directly into a feed channel (10) and fill a metering or dosage chamber. The contents of this chamber are passed to the pan of a weighting device. Adjustable metering flaps (54) distribute the fine component of the tobacco over the central region (52) and side regions of a base (53) beneath the grille (50). Financial loss is reduced by approaching the wanted weight of the portion from below - adding fine tobacco particles gradually - instead of allowing the portion's weight to overshoot the wanted value. Repeated overweighing, from e.g. tobacco clumps is avoided.

Title: Switch contact rebound prevention - is by synthetic material or spring absorption pad behind struck contact
Inventor: BORNSCHEIN WALTER
IPC: H01H1/50
Filed: 1979-05-15
Abstract: Mechanical contact bounce elimination is for microswitches and relays. It uses a synthetic material block. The synthetic material small block or tablet is inserted behind the contact to be struck and is sufficiently elastic to absorb the energy of the striking contact and prevent the bounce which would occur against a rigid contact structure. Instead of the synthetic material block an alternative is to place a compression spring behind the contact being struck. The method is confirmed contact bounce free by oscillograph tests monitoring for even 1/5,000 sec bounce. The changeover spring (4) comes from the microswitch operating unit to the fixed contacts (2,3). The rest contact (2) is not equipped for bounce elimination but the other contact (3) has a synthetic material tablet (6) between its spring contact carrier and conductor (5) and the switch body (9) supports. All is held firmly in place by the bolt (7) and hexagonol nut (8).

Patent DE-3020979-A1 (DE)
Inventor: MEISSER CLAUDIO
IPC: G01F25/00
Filed: 1980-06-03
Abstract: In order to calibrate volumetric flowmeters (7) for large quantities of liquid, two delivery cylinders (1, 2) are used which are connected in parallel and the pistons (5, 6) of which alternately deliver liquid from one cylinder chamber (10, 12) via a valve system (8) and a test piece (7) to the other cylinder chamber (9, 11). The piston (6, 5) of the other delivery cylinder (2, 1) returns during the delivery period of the first delivery cylinder (1, 2) and, controlled by the valve system (8), permits liquid to flow back out of one cylinder chamber (12, 10) through a tubular section (36) into the other cylinder chamber (11, 9). The return stroke of the piston (5, 6) is more rapid than the forward stroke. During a short period in which the two pistons (5, 6) run in the same direction, the valve system (8) rapidly switches to the other delivery cylinder (2, 1) and simultaneously opens a flow path (36) for the return of one of the pistons (5, 6). <IMAGE>
