Patent DE-3120862-A1 (DE)
Title: Shears, in particular for cutting off a veneer pack
Inventor: KREDER HANS
IPC: B23D15/08
Filed: 1981-05-26
Abstract: So that a veneer pack, for example, can be cut off alternatively or simultaneously in the fibre direction and/or transversely thereto with shears and in order to avoid unfavourable, one-sided loading of the pressure beam in the event of the veneer pack only being cut off transversely to the fibre direction, a second pressure beam is provided in addition to the first pressure beam, the second pressure beam being displaceably guided on the first pressure beam in a preferred manner. It is thereby possible to set to different depths alternatively only the second pressure beam or both pressure beams together or both pressure beams independently of one another. The second pressure beam is provided with a synchronizing device so that it does not tilt if the width of the veneer stack is less than its width. Since the cutting blade extending over the length of both pressure beams is also fed in during cutting merely in the transverse direction of the fibres by means of the second pressure beam, the entire working area must also be monitored by means of a safety device and an additional safety device in this mode of operation, the additional safety device being inoperative if work is carried out with the first pressure beam without separate infeed of the second pressure beam.

Patent DE-3208993-A1 (DE)
Title: Packaging container
Inventor: ERNESTI CLAUS
IPC: B65D81/32
Filed: 1982-03-12
Abstract: The invention relates to a packaging container for the separate storage of two different flowable products which have to be mixed before use. The packaging containers which have become known hitherto for this purpose are of too complicated design and are too expensive and therefore have not been successful on the market. What is proposed is a deformable outer container (1) having a head part (4) which is formed in one piece and in which is arranged an inner container (2) consisting of a cylindrical body with a membrane seal (3). The inner container (2) can be displaced axially counter to the resistance of a spring (7) as a result of pressure on the outer container (1), in such a way that pins (5) formed on the head part and pointing inwards pierce the membrane seal, with the result that it becomes possible to mix the two products, with a closing cap (10) closed.

Title: Tractor-mounted appliance for groundworking, especially for seedbed preparation
Inventor: WIENHOFF HELMUT
IPC: A01B33/02
Filed: 1982-03-23
Abstract: The invention relates to a tractor-mounted appliance for groundworking, especially for seedbed preparation, with a supporting frame which is oriented transversely to the direction of travel of the tractor and which carries positively driven working implements working the ground surface. Groundworking appliances driven from a power take-off shaft and having at least one positively driven tine bar oscillating to and fro have become known. It has been shown that ground unevenness occurring during the groundworking cannot be filled up with earth sufficiently and that stones can become jammed between the tines. The object on which the invention is based is to provide a groundworking appliance which distributes the clods of earth effectively, compensates ground unevenness, is insensitive to obstructions, such as, for example, stones, in the ground and at the same time eliminates travelling tracks of a tractor. This object has been achieved, according to the invention, in that the working implement is a worm shaft oriented transversely to the direction of travel of the tractor and parallel to the ground surface and having radially projecting worm wings.

Patent DE-3231886-A1 (DE)
Title: Front panel for an electronic assembly, and a method for producing this front panel
Inventor: KELLER ROMAN
IPC: H05K7/14
Filed: 1982-08-26
Abstract: The front panel has a projection (1b) which is constructed as a rib which runs over the entire length of the front panel (1) and has a constant cross-section. The front panel (1) thus has a T-shaped cross-section. This rib is used for the attachment of a printed-circuit board (2). The inside of the front panel (1) and at least one side surface of the rib (1b) can be provided with a metal screen (1d, 1e). Such a front panel can be produced particularly easily using the extrusion method, and can be cut to length to correspond to the desired front-panel height. In this case, a metal strip (1d, 1e) can be pressed in simultaneously as the metal screen. Using the extrusion method, a front-panel profile is obtained as an item sold by length, which has to be produced only in a few different widths and thus offers advantages with respect to production disposition and storage. <IMAGE>

Title: Liquid-crystal cell and its use
Inventor: WALTER KARL-HEINZ DIPL ING
IPC: G02F1/1337
Filed: 1982-09-14
Abstract: A liquid-crystal cell switches relatively quickly if the liquid-crystal film (12) does not respond in its totality, but only in a thin layer close to the surface, to the electric field. In order to meet this condition, it is proposed to provide at least one of the two support plates (2, 3) with a certain orientation pattern on its contact surface with respect to the liquid-crystal film (12): the direction of orientation changes periodically in two directions parallel to the plate but perpendicular to each other; each period includes two different orientations and is, at most, 10  mu m long. In a preferred configuration, the support plate (2) is coated with an orientation film (9), the surface of which is a mosaic of areas (13, 14) arranged in chequerboard fashion and aligned homogeneously or homeotropically. The impressed microstructure very quickly disappears with increasing distance from the plate (2); it is, furthermore, stable over many switching cycles and, moreover, produces optical effects without disturbing directional dependence. Main area of application: in the transmission of electric signals as a transmitter-controlled light valve. <IMAGE>

Title: Ship
Inventor: WAAS HEINRICH DR ING
IPC: B63B35/12
Filed: 1982-10-30
Abstract: The forebody of the ship with low power requirement in open and ice-covered water has over the entire ship breadth an end face (301) inclined forwards at the top and having marginal cutting edges (305), preferably at bar-like profiles (303), the end face (301) merging into an underwater part of the forebody having frames (310) in a V-shape at the bottom, while the cutting edges (305), which forward above the water line (302; 302a) can merge into two catamaran-like stems (311), and the end face (301) are of curved design in the longitudinal direction. In the centre area of its longitudinal extent, in particular below the construction water line (300), the end face (301) is supported by frames running horizontally athwartships at the bottom and approximately forms a plane there. An ice-cutting centre runner (304) is arranged on the forebody in the midships longitudinal direction. Even when the nature of the ice varies greatly, favourable conditions are created for the breaking-up of one-piece ice flows. The one-piece ice flows split centrally under water into two halves floating away to the side below the solid ice cap, in the course of which fragmentation into many pieces is largely avoided. <IMAGE>

Patent DE-3310430-A1 (DE)
Inventor: OTTOFRICKENSTEIN HANS
IPC: A23C21/02
Filed: 1983-03-23
Abstract: A process and reactor are disclosed for the continuous treatment of a turbid liquid with a granular treating agent placed in a fixed bed through which the liquid flows. Preferably, the liquid is whey and the treating agent is lactase immobilized on support particles, and treatment involves hydrolysis of lactose in the whey. During treatment, the flow of whey through the fixed bed is periodically interrupted and a flow of cleansing liquid is passed through the fixed bed countercurrent to the flow of whey. The flow of cleansing liquid is under sufficient hydrostatic pressure to press the fixed bed against moving fragmentation devices to separate and fluidize the support particles into a fluidized bed whereby the support particles containing immobilized lactase are cleansed by removing material deposited thereon from the whey.

Title: Saw horse
Inventor: RITTER EUGEN
IPC: B27B17/00
Filed: 1983-05-03
Abstract: Saw horse, in particular for dividing up material to be sawn by means of a hand-held motor saw, consisting of side parts which are connected to one another via longitudinal struts, each side part consisting of forked struts which form a receiving space for the material to be sawn and a clamping element firmly clamping the material to be sawn in the receiving space. With such a saw horse, it is not possible to saw a stack of wood quickly and cost-effectively. In actual fact, there is even an increased risk of accidents. For this reason, it is proposed that the forked struts forming a side part be connected to one another in the transverse direction via a transverse strut on which the material to be sawn rests, that the longitudinal struts be arranged underneath the receiving space, and that each side part be assigned a clamping element.
