Patent DE-3222577-A1 (DE)
Title: Double-eccentric drive for oscillating positive-displacement pumps
Inventor: EICHLER WOLFGANG
IPC: F04B49/12
Filed: 1982-06-16
Abstract: In the case of a double-eccentric drive for oscillating positive-displacement pumps, the stroke of the displacer is adjusted by turning the outer eccentric with respect to the inner eccentric by utilising the forces which act between the two eccentrics during rotation of the double eccentric and change their direction once during a rotation, for the purpose of turning the eccentrics in each case when this operating force acts in the direction of the desired stroke adjustment. To this end, a preferably hydraulic or mechanical coupling is arranged between the two eccentrics and is released in each case when the operating force has the corresponding direction. As a result, an adjustment of simple design with low actuating forces is possible during the operation of the positive-displacement pump.

Patent DE-3313809-A1 (DE)
Title: Vessel
Inventor: CHIBA KAZUO
IPC: B63B3/44
Filed: 1983-04-15
Abstract: The vessel, for example a ship, a boat or the like, has a form in which the starboard and port side plate has a part projecting by a predetermined length beyond the bottom so that the hull of the vessel has an H-shaped cross-section, the bottom half being shorter than the top half. The bow part consists of a flat bow plate which curves forward to the top so that water located in front of the vessel is conducted into a space which is defined by the bottom plate and the side plate. A flow producing a buoyancy pressure therefore develops during forward motion of the vessel. The two side plates have a part projecting from the bottom by a predetermined length so that the water flow producing the buoyancy pressure cannot escape from the said space in the transverse direction. If the vessel is ever lifted from the water, it moves forward on account of its inertia force as if it skims on the water. The side plates preferably have a further part projecting forward beyond the bow plate and projecting down beyond the base plate. The side plates are attached at right angles relative to the bottom plate. The water flowing into the space located below the bottom of the vessel is therefore split up into an internal flow and external flows.

Patent DE-3322193-A1 (DE)
Title: Method for scanning bar code markings on objects transported along a conveyor belt
Inventor: DUDZIK JOACHIM
IPC: B07C5/34
Filed: 1983-06-21
Abstract: The drums transported on a conveyor belt are provided, for the purpose of automatic detection and recording, with bar code markings (16) which are scanned by means of a scanning head (26) in a scanning station (22) and are decoded. One problem in the scanning of the bar code markings consists in that the rotationally symmetric drums (12) on the conveyor belt (20) arrive in irregular sequence in the scanning station (22), with the bar code marking (16) being differently aligned and partially also with lateral offset with respect to one another. To ensure reliable scanning, the drums (12) are stopped by means of stopping barriers (24) obliquely intervening on the conveyor belt (20) and are centred. The scanning head (26) is then pivoted over the drum by at least 360 DEG  about an axis approximately coincident with the axis of symmetry of the stopped drum (12) so that the marking is detected by the scanning beam in every case. <IMAGE>

Title: Vapour steriliser
Inventor: SAUPE MARTIN
IPC: A61L2/07
Filed: 1984-03-24
Abstract: A vapour steriliser for the pressureless treatment of goods to be sterilised works with the vapour from a liquid whose boiling point at the pressure of the ambient air is above the sterilisation temperature and whose vapour is heavier than air. A container (1) has a heatable liquid-accommodating space (5) at the bottom and a sterilisation zone (7) above this. A cooling path (12) adjoins with its upper end (13) the sterilisation zone (7), extends outside this zone and is connected by its lower end (14) above the liquid level (15) to the lower part of the sterilisation zone (7). Vapour from the sterilisation zone (7) can be supplied to at least one cooling zone (18, 19) even after the heating device (8) is switched off in the liquid-receiving space (5). In this way, the vapour level in the sterilisation zone (7) can be reduced and the goods to be sterilised can be removed free of residual vapour. <IMAGE>

Title: Vacuum box for curing photopolymerisable plastics
Inventor: PAULI KARL-HEINZ
IPC: B29C35/08
Filed: 1984-08-03
Abstract: In order to avoid the greasy film forming on the plastic surface during photopolymerisation as a result of atmospheric oxygen, it has proved advantageous, after the application of all plastics layers, their curing and the polymerisation operations necessary for this, to carry out the last curing process under vacuum. The lightweight, transparent and readily portable device described with a weight of approximately 250 g permits photopolymerisation of the applied coating under vacuum, after the application or brushing on of a photopolymerisable coating layer onto the still greasy plastic surface. The object to be surface finished can be removed again from the device in a highly glossy state after a short time. Postpolishing is no longer necessary after this.
