Title: Polishing wheel with elastomeric abrasive sheets - consists of hub with circumferential slots for circular rims of sheets
Inventor: GATERMANN BODO
IPC: B24D13/06
Filed: 1975-05-31
Abstract: The polishing wheel consists of a hub (2) with eighteen axial grooves (3) spaced evenly around its circumference. The grooves are of part circular section. The sheets of polishing material (1) are made from a homogeneous elastomer in which abrasive particles are embedded, or from an elastomer which is reinforced with glass fibre. Each sheet has a rim of circular section along one edge which is slid into a groove in the hub. The rim is at an angle to the rest of the sheet, so that when the sheets are mounted in the hub, they partly overlap one another.

Title: Typewriter with colour and white ribbons - latter in assembly to correct errors
Inventor: CHO CHI LIANG
IPC: B41J29/36
Filed: 1975-06-06
Abstract: The white ribbon is arranged in an assembly (b) including a pair of spools mounted on a slide movable along a groove in the type bar cover and normally situated to one side of the typing position.

Title: Composite prodn. from graphite and high melting metal parts - using solder and coating on graphite contg. carbide forming metal
Inventor: MELTON KEITH N DR
IPC: H01H1/027
Filed: 1975-06-19
Abstract: Prodn. of a mechanical and electrically-conducting combination of a graphite part with a high-melting metal part, pref. of Mo or W or a Mo- or W-based alloy comprises providing the graphite part with a surface coating of a carbide-forming metal and bonding the appropriate surface of the high-melting metal part of this with a solder contg. carbide-forming metal(s). The metal coating and/or the solder can be applied by plasma spraying or vapour phase deposition. A Cu- or Ni-based solder pref. is used. The claims also cover the composite and its use as material for electric arc electrodes and contacts, esp. of SF6 circuit breakers. The composite has greater mechanical strength than graphite and favourable electrical conductivity. The bond is so strong that tensile failure occurs in the graphite, rather than in the bonding layer.

Title: Multi surface slide bearing with wedge form lubricating surfaces - is produced by permanent deformation of suitably machined bush
Inventor: RICHTER JOACHIM
IPC: D01H4/12
Filed: 1975-06-21
Abstract: A multi-surface slide bearing with a number of slide surfaces distributed round it circumference, has a bearing bush and/or a support bush enclosing the bearing bush, machined with grooves, bores or cutouts.

Title: Fixing member holding induction coil assembly to plate - has sleeve that deforms on tightening screw to relieve forces on plate
Inventor: STEINBEISSER WERNER
IPC: H01F17/04
Filed: 1976-07-26
Abstract: The fixing member, for holding an induction coil assembly to a base plate, is flexible and consists of a sleeve (5) between the plate and the under edge of the induction coil assembly and a retaining angle acting on the upper edge of the assembly. A screw draws the fixing member down so that the retaining angle presses down on the assembly. The sleeve is cut away at the outer part of its bottom face and has a radial projection (11) extending inwards from its top face. As the screw is tightened the sleeve tilts (deforms) and the projection raises the coil assembly. This prevents retaining forces caused by the assembly's bending from fracturing the base plate.

Title: Water vapour intake system for IC engines - uses metered water vapour and waste engine heat to provide steam heat
Inventor: KAHLOW HORST
IPC: F02M25/022
Filed: 1976-10-07
Abstract: The water vapour should be introduced into the combustion chamber in order to smooth out high pressure peaks. The water is to be vapourised by using waste engine heat. The water vapour is metered and fed to the combustion chamber with out condensation particles. A critical temp. of 374 deg.C is to be maintained. The vapouriser should belocated as close as possible to the exhaust valves. In computing the amount of water required per litre of fuel, air humidity is included. It estimates that one litre of fuel requires 10,000 litres of air which will contribute 100 to 120 grammes of water. A special air filter is recommended to avoid water absorption.
