Patent DE-2530284-A1 (DE)
Title: Lighting fitting with crossed gas discharge lamps - has reflector of crossed dome shape with antiglare frame
Inventor: BARTENBACH CHRISTIAN
IPC: F21S8/02
Filed: 1975-07-07
Abstract: Lighting fitting holds a number of gas discharge lamps. On one side of the discharge lamps is arranged a reflector. In front of the lamps is arranged a dazzle protection frame, and the fitting ensures uniform distribution to all sides over a relatively wide conical area in front of the light fitting. The gas discharge lamps are arranged into cruciform pattern. The rectangle formed by the end points of the lamps is covered by the reflector which is designed as two intersection domed curves which become vertically flat surfaces at the reflector edges. The four edges of the reflector form the limiting plane for the glare preventing frame.

Title: Shaped plastic abrasive elements - cong. urea-formaldehyde, abrasive and hardener
Inventor: ATKINSON GORDON ANDREW COLNE
IPC: C08J5/14
Filed: 1975-08-27
Abstract: Shaped plastic abrasive element comprises a mixt. of a urea-formaldehyde resin, an abrasive agent and a hardener. Pref. the mixt. contains 40-70 wt. % (esp. 55-65 wt. %) urea-HCHO resin, 30-60 wt. % (esp. 20-35 wt. %) abrasive agent and 4-8 wt. %. (esp. 5.5-6 wt.%) hardener. The abrasive agent may be kieselguhr, ground quartz alumina, silicon-carbide, or a mixt. of such abrasives, and may be in granulate form. The mixt. pref. also contains 5-15 wt. % of urea, which may be in powder or crystalline form. The hardener is pref. present in amt. of 1/10 of the wt. of the urea-HCHO resin. The use of urea-formaldehyde resin as carrier avoids the disadvantage of foam-formation previously obtd. with polyester resins, and moreover not lead to the same difficult pollution problems as polyesters media.

Title: Synchronizing mechanism for gear box - has lever as coupling member between synchronizing ring and gear wheel
Inventor: DROESCHEL HELMUT
IPC: F16D23/06
Filed: 1975-09-01
Abstract: The synchronizing mechanism is for a changeable gear coupling esp. in a gear box. It has a stipulated main coupling. One side has inclined limited surfaces on the gear-shift sleeve. The other side has a synchronising ring with rotational play. This arrangement gives the necessary limiting effect by gear change to synchronization. A number of friction laminations are provided with changeable inner and outer projections. These laminations convey the rotation by friction between the synchronizing ring and the coupled section - normally the gear wheel. Some of the projections engage in the synchronizing ring while the others are moved along the gear wheel to engage it. The last lamination is in the form of a pressure ring.

Title: Small multi-purpose electric kiiiitchen mincer etc. - has perforated plate driven by electric motor across bottom of vertical cylinder with lever-operated plunger
Inventor: KNOEPFLER DIETER
IPC: A47J43/25
Filed: 1975-09-20
Abstract: The working part of the multi-purpose kitchen machine is a vertical cylinder with a perforated plate across the bottom. A radial partition halfway across at one point prevents the food going round with the perforated plate, instead of through it. A lever-operated plunger presses the food down. An electric motor in a separate, and separable compartment drives the perforated plate by means of gears. A central pin supports the middle of the plate, which is attached to the cylinder by a ring with a bayonet fixing. A handle on the cylinder that houses the plate, and another handle opposite it, on the motor compartment, enables the machine to be hand-held over a basin.

Title: Gate with steep transfer characteristics - has reference voltage coupled to input transistor emitter via diode or diode and resistor
Inventor: KOTTE WILLI DIPL ING
IPC: H03K19/003
Filed: 1975-10-14
Abstract: The TTL or DTL gate can be readily integrated and consists of a diode connected between the input transistor emitter and the reference potential (e. g. OV). The diode may be replaced by a diode network, or by a diode in series with a resistor. Alternatively, instead of a discrete resistor the resistance of the diode itself may be employed. The diode may be a Schottky barrier type. The advantage lies in the gate having steep transfer characteristics.

Title: Gritting control for car wheels - with heated grit reservoirs and grit release coupled to brake operation
Inventor: FRIEDRICH KURT
IPC: B60B39/08
Filed: 1975-12-13
Abstract: Grit reservoirs are mounted in front of each wheel and have a double skinned construction. The space between the walls is heated by coupling it to the cooling water circuit or by passing some of the exhaust gases through it. The grit can also be heated by heating coils in the grit to prevent it clogging. The release of the grit is automatic, linked to the operation of the brake pedal, with a main control switch to prevent release in normal driving conditions. The system provides good wheel grip on roads where spiked tyres are banned, without having to fit snow chains.
Patent DE-2558153-A1 (DE)
Title: Coloured interference films on alloys contg. chromium - stabilised and hardened by immersion in hot aq. soln. of anionic surfactant
Inventor: RUHSTORFER FRIEDRICH
IPC: C23C22/83
Filed: 1975-12-23
Abstract: Coloured interference films on the surfaces of chromium alloys are stabilised by post-treatment, after the films have been produced by immersion in baths contg. chromic acid. The novelty is that the coloured workpiece is immersed for 1-10 minutes in a hot, aq. soln. contg. by wt. 0.05-5% anionic surfactants, possibly together with non-ionic surfactants. The coloured workpiece is pref. immersed 3-5 minutes in an aq. soln. at 50-65 degrees C. contg. 1% anionic surfactants. The coloured interference film may first be hardened by making the workpiece the cathode in an electrolyte contg. chromic acid before the post treatment in the surfactant soln. Alternatively, the interference film may be mechanically compacted before immersion in the surfactant soln. for stabilisation. Process is suitable for stabilising and increasing the wear-resistance of films applied to stainless steels, e.g. Cr-Ni steels or Cr-steels, where the interference film is 0.05-0.3 u thick. The initial interference film is not normally very hard and has a scratch resistance of e.g. 10 g. Method raises the scratch resistance to 1700-3700 g.

Title: Frictional infinitely variable gearing - has rings driving cones axially movable to vary transmission ratio(NL030277)
Inventor: KEMPER YVES JEAN
IPC: F02G1/043
Filed: 1976-07-30
Abstract: The infinitely variable gearing comprises an input shaft driving a tubular swash body. Two drive rings are mounted inside the swash body concentric with the swash axis. The rings surround and have rolling friction drive engagement with respective driven cones arranged, big ends adjacent, on an output shaft coaxial with the input shaft. Springs urge the rings along the swash axis toward the big ends of the cones. The cone angles are the swash angle so that when the cones are moved axially in opposite directions the rings must follow along the swash axis to change the transmission ratio. The movement of the cones is effected by fluid pressure system through the output shaft.

Abstract: Sealing and packing material comprises short PTFE fibres intimately mixed with graphite and opt. with an oil such as a silicone oil, paraffin oil, mineral oil, or polyhydric alcohol. Pref. the PTFE fibres have a titer of 2-50 dtex and a length of 3-7mm. The graphite pref. has a purity of >95%, esp. >99%. The compsn. may also contain finely divided PTFE. A pref. compsn. contains >=50 wt. % PTFE fibres, 10-30 wt. % graphite and 5-15 wt. % finely divided PTFE. After mixing the components, the compsn. may be pressed into tablets. The packing materials are esp. useful as seals in pumps, etc., to seal rotating shafts against leakage.

Title: Machine for attaching fasteners to garments or leather articles - has jaws of fastener gripping mechanism actuated by punch motion through toggle linkage
Inventor: FRANKE HANS-JOACHIM DIPL ING D
IPC: A41H37/00
Filed: 1976-09-29
Abstract: The machine for attaching fasteners e.g. press studs to garments or leather articles has a punch (8) driven through a toggle linkage (3, 4) which is actuated by a pedal. The motion of the punch is utilised by the levers (5, 6) to impart an oscillating motion to the slider (14) which pushes the fasteners underneath the head (9) of the punch (8). The fasteners are stored in the drum (11) and slide down a chute to the slider (14). The punch (8) is fitted with a projection which engages a lever. This in turn opens and closes the jaws of a mechanism which grips the fasteners whilst they are being pressed into the garment.
