Patent DE-2805382-A1 (DE)
Title: Vehicle gearbox with coupling for each stage - has stage for first forward and reverse groups hydraulically engaged and spring disengaged
Inventor: ZENKER WALTER
IPC: F16H61/02
Filed: 1978-02-09
Abstract: The control unit is for a vehicle gearbox with two forward and one reverse gear groups, each with its own coupling. The two couplings for the first forward and the reverse groups are hydraulically engageable and disengaged by spring force, whilst the coupling for the second forward gear group is operated in the opposite manner. Between the first forward and the reverse couplings is an exchange valve whose output is connected to the second forward coupling via a throttle. With the first forward gear coupling disengaged, the second forward coupling and a pressure medium pump have a throttle connected via a slide valve.

Title: Wire coiling machine with turntable to remove coils - has hinged mandrels operated by jacks to place coils on trolleys
Inventor: WOLLGARTEN ROBERT
IPC: B21C47/24
Filed: 1978-03-09
Abstract: A wire coiling machine winds the wire onto a mandrel and then allows the completed coil (R) to fall onto a second mandrel. The mandrel is one of four fixed to pivoted arms (9) with their outer ends supported on rollers (9a) so that they can rotate in the horizontal plane. After each mandrel has been rotated through 180 deg. it is swung outwards by a jack so that the coil lies between the sides of the trolley. The trolley then pulls the coil off the mandrel and carries it to the crane hook.

Title: Vehicle window cable lifter guide - is formed as slotted plastics tube with surrounding support engaging extensions on lifting slide
IPC: E05F11/48
Filed: 1978-04-25
Abstract: The cable guide for the lifting mechanism of a vehicle window pane is in the form of a plastics tube (2) with a longitudinal slot. A carrier member (8) is secured to the cable (7) and runs in the guide. Part of the carrier projects through the slot in the guide and is splayed out to join to a lifting slide (6) connected to the window pane. A slotted support tube (20) partly surrounds the cable guide, and has a side projection (1) engaging a slot (24) in extensions (4, 5) on the lifting slide. The movement is thus maintained square during operation.
Patent DE-2819784-A1 (DE)
Title: Continuous annealing plant for steel strip - with large dia. guide rollers preventing strain ageing during controlled cooling
Inventor: PAULUS PHILIPPE
IPC: C21D9/56
Filed: 1978-05-05
Abstract: A continuous annealing plant for sheet, esp. soft steel sheet for drawing, includes a furnace for averageing or the pptn. of carbon; the sheet or strip travels horizontally along a reduced number of very long paths which limits the number of guide rollers used to reverse strip direction, so very few rollers, or possibly no rollers, are required. When furnace uses the guide rollers, the latter should have the max. possible dia., and the pref. plant has (a) a heating zone raising the steel to above its recrystallisation temp.; (b) a temp. soaking zone; (c) a quenching zone using an aq. bath above 75 degrees C. (d) furnace (1); (e) final cooling zone. Horizontal furnaces may also be used for stages (a, b). The use of very long paths and the min. number of guide rollers reversing strip direction, where the max. possible dia. is used for the guide rollers, reduces strain ageing which can occur due to the passage of the strip round the rollers.
Patent DE-2820228-A1 (DE)
Title: Impact damping hand-operated label printer - has spring-loaded ball engaging arresting surface on base body or hand lever

Title: Absorber element for solar heat collector - with plastics tube and two shades of sheet metal stampings
Inventor: REUSCH HEINZ DIPL ING
IPC: F24S10/75
Filed: 1978-05-13
Abstract: The absorber element for a solar heat collector consists of a platic hose which is held between two metal plates. To save the costs of expensive press dies, one of the two plates is flat. The meandering hose is held on it by pot welded pieces of plates, one with a straight groove fr the straight section of the meander and one with a U-shaped groove for the double bend. The preferred material for the plates is aluminium or galvanished steel, and for the hose PTFE. The result is a low-cost absorber element which is simple to make in any size.

Title: Silencer for IC engine for garden tools - has side shaped to form venturi to draw in cooling air
Inventor: MAETHNER MANFRED
IPC: F01N13/00
Filed: 1978-05-26
Abstract: The casing (10) of the silencer is assembled from two halves (11, 12). There is an inlet (15) from the engine in one half and several outlets (20) opposite it in the other half. A baffle plate (30) is held off the side (13) of the silencer to form a passage (31) in which ambient air is drawn in to mix with the exhaust before the exhaust is discharged (36) near the ground. The discharge side (13) of the silencer is angled inwards just below the last exhaust outlet (20). Together with the flat baffle plate this results in a venturi shape of the passage between them, which promotes a good air flow.

Title: Magnesium and calcium salts of carboxy:alkylthio-acetic acids - with mucolytic, immuno:regulatory and antiarthritic activity
Inventor: JOULLIE MAURICE
IPC: A61K31/185
Filed: 1978-09-05
Abstract: The Mg and Ca salts of acids of formula HOOC-(CH2)n-S-CH2-COOH (I) are claimed (where n is 1-5). The salts have similar mucolytic activity to the free acids and other salts (see DT 2548669), but also have immunoregulatory and antiarthritis activity. E.g., the Mg salt of (I; n is 2) inhibits the humoral immune reaction to i.v. injection of lipopolysaccharides and has higher activity than D- penicillamine against induced polyarthritis in rats. The salts are prepd. by reacting (I) with Ca(OH)2, Mg(OH)2, CaCO3 or MgCO3, pref. in stoichiometric proportions.

Title: Electrode driving circuit for resistance welding machines - uses counterbalanced pneumatic cylinder minimising noise when electrode meets workpiece
Inventor: THIEROLF LEONHARD
IPC: B23K11/31
Filed: 1979-04-17
Abstract: The electrode is driven towards the workpiece by a piston rod and a piston, which is located in a pneumatic cylinder below a floating piston, which provides part of the stroke of the electrode. The cylinder is connected via a network of pipes and valves to a main supply of compressed air, which drives the electrode towards the workpiece; and also to a counter-current of compressed air used to retract the electrode. The floating piston is used to operate electric contacts in an electric circuit using a preselected timing sequence to operate solenoid valves controlling air flow (M,C). The electrode hits the workpiece at a controllable speed, so electrode wear is minimised and distortion of workpieces is prevented in addn. to noise redn.
Patent DE-2917344-A1 (DE)
Title: Moulding tool for components of resin bonded carbon fibre - has sealing mask enclosing mould details in autoclave
Inventor: SCHINDLER RUDOLF
IPC: B29C43/12
Filed: 1979-04-28
Abstract: A reusable, flexible, heat-resistant mask with wall sections extending across the moulding cavity, forms the seal for a mould assembled from a number of components, for the production under heat and pressure of mouldings from a thermosetting-resin-bonded fibrous material. The moulding cavity delimited by components which move in combination with each other, is sealed pressure-tight and is subjected to heat and presure from outside. The contours of the mask wall sections correspond to those of the mould components to be sealed. The seal is made by tenons which engage in grooves in the mould components. The mask complete with tenons is in one piece and is of a material with a higher coefficient of thermal expansion than the mould such as silicone rubber. A connection to vacuum is provided at the outlet from the mould for the gases generated. The mask supersedes the wrapping of the moulds in a vacuum film with an intermediate layer of porous material, followed by the time consuming trimming of the moulding by a diamond disk. It makes possible cheap, rational and accurate mass production of the bonded fibre mouldings in autoclaves.
