Title: Deep drawing hollow ware from metal sheet - where mechanical and hydraulic drawing are combined to obtain max. drawability
Inventor: TOMASEK JIRI DIPL ING
IPC: B21D22/20
Filed: 1978-12-09
Abstract: The process uses a lower die forming a drawing chamber (a) contg. pressurised fluid supplied and/or drained via a valve. Chamber (a) is connected via a channel to a cavity (b) in which a sheet metal blank is placed; and when a punch drives the blank into chamber (a), part of the fluid is driven into the cavity (b), where it exerts pressure on the periphery of the blank. One pref. tool set consists of a lower- and an upper-die fitted with seals to form cavity (b); and chamber (a) has an adjustable drain valve, controlling the exit of fluid and therefore the amt. driven into cavity (b) when the deep drawing punch is lowered. The drawing coeffts. of the metal blanks are increased so the forming capacity of the metal can be fully exploited.
Patent DE-2855624-A1 (DE)
Title: Typing system using dot pattern - operates in separate periods within indexing movement of typing head
Inventor: BAUR KARL
IPC: B41J2/505
Filed: 1978-12-22
Abstract: The typing system produces letters and numbers in dot patterns, using a comb indexing along the typing line, the typing operation taking place during comb movement. Typing takes place in a series of period separated by intervals within an indexing movement, so that a number of separate dots can be typed within the width of such a movement. In the thus widened dot pattern the dots for a symbol are typed at an interval such that the number of dots per gap is equal to a number p, or one less than it.

Title: Film transporter for continuous process equipment - has elastic claws for film edges with facility for handling separate film loops
Inventor: LEUCHTER JUERGEN
IPC: G03D3/12
Filed: 1978-12-29
Abstract: The transporter for film strips for a continuous process equipment has the flexible grips (25) secured on a transport belt (11), to grip the edges of the film strip. The grips are so shaped that there is a flat step in the grip area to allow the film to move at right angles to the transport band to accommodate changes in length through the wet and dry processes. The film is loosely held, without tension. Narrow film strips can be accommodated by a second set of closely spaced clamps under the belt. The clamps are moulded from plastics and do not affect the processing fluids nor do they damage the film edges. The film strips do not have to be spliced into a continuous length and can be processed in any lengths.

Title: Relay contact space sealing - by laminated foil of polyethylene and polyethylene terephthalate
Inventor: SCHWAB GUENTER
IPC: H01H49/00
Filed: 1979-01-12
Abstract: The contact space of an electromagnetic relay is protected against the ingress of casting resin by applying a sealing foil to the face ends and the adjacent sides of the spool. The foil is pref. laminated and is applied by heated plungers. The layer towards the spool which is plastically deformed thereby consists of polyethylene. The outer layer has a higher heat resistance and is pref. made of polyethylene terephthalate. The overall foil thickness is 0.1 mm, with polyethylene accounting for more than half. This prevents any contamination of the contact space by adhesives and can be readily mechanized.

Title: Sugar beet tops catch finger - with forward abutment on flexible mount and differential rear lugs
Inventor: GERLACH GUENTER
IPC: B01D43/00
Filed: 1980-07-11
Abstract: The Parent Patent described a system for picking up sugar beet tops from a water transport channel by catch fingers, mounted by flexible means to crossbars on endless straps. The movement of these catch fingers has now been restricted in the forward direction of movement. A face on the catch finger abuts with a face on the crossbar to give it a slight rearward inclination. This prevents the catch fingers from flapping into the water on their down movement and turns them gently on passing deflection pulleys so that the sugar beets are not damaged.

Title: Loading bay door sealing curtain - connects fixed and movable lintels to adjust to size of vehicle
Inventor: KOCH ROBERT
IPC: B65G69/00
Filed: 1980-09-12
Abstract: Closure device for the vehicle access opening of a loading bay, warehouse etc., fits approx. around a vehicle backed into the opening but not passing completely through it, for the purpose of loading or unloading. The doorposts of the door opening are faced with beadings (5) of semicircular cross-section, while a similar beading (7) forms the lintel to the opening and can be lowered according to the height of the vehicle. This lintel is connected to the fixed door lintel above it by an adjustable movable sheet of material, pref. a fabric sheet coated with PVC and wound up on a roller. This arrangement enables the greater part of the door opening to be fully sealed against wind, dirt, etc. in spite of large differences in sizes of vehicles using it.
