Patent DE-2337475-A1 (DE)
Title: Wing mirror mounting foot - with access panel for easy access to fitting screws and adjusting bolt
Inventor: ERLEWEIN OTTO
IPC: B60R1/06
Filed: 1973-07-24
Abstract: The wing mirror is fitted to a streamlined, hollow foot which screws to the vehicle. The foot has an access hole on the outside through which the fitting screws and adjustment bolt for the mirror are reached. The hole is grooved on either side so that a flexible cover can be clipped in to protect the inside from dirt and water, while hiding unsightly fittings. The bottom of the panel has a drain hole. The system is especially useful for good access for the linkage of remote controlled mirrors.
Patent DE-2341633-A1 (DE)
Title: Protective coating for metal surfaces during heat-treatment - esp. for selective carburising and nitriding in salt baths
Inventor: HEINEMANN WOLFGANG DIPL-CHEM D
IPC: C21D1/70
Filed: 1973-08-17
Abstract: Refractory materials in the form of foils, woven fabric and/or fibres are used on those regions which are not to be case-hardened, and the pref. material is graphite. Although many materials have been developed as masks to prevent case-hardening in the gaseous phase, none has proved satisfactory in salt baths, whereas this invention provides materials which are satisfactory. In addn. to graphite, boron nitride, silicon carbide and zirconium dioxide can be used; these materials also have an insulating effect so that the cooling rate of the coated regions is altered.

Title: Ferrite pot-core assembly arrangement - uses ferrite bell core screwed onto roll core with coil winding and spring attached tag-plate
Inventor: JERNEY RUDOLF
IPC: H01F5/04
Filed: 1973-09-03
Abstract: The ferrite core consists of a roll-core and screwable on to it a bell shaped core. An insulating connection support carries the contact pins. The roll-core has at its upper end a collar carrying a thread. The coil winding is located on the roll-core below the collar. To the connection support in the region of its free ends are fixed undercut spring elements which with their undercut ends grip with spring tension into corresponding formed areas of the bottom flange of the roll-core. In this way the roll-core is firmly pressed and held to the connection support plate. Central drilling in the support plate and the roll core make adjustment plug insertion possible. The arrangement represents a considerably simplified and releasable assembly for the coil to the pin board. The assembly process is repeatable without wear of the parts and without any special tool.

Title: Shell and tube heat exchanger - with elastic PVC shell and tubes helically twisted round tube bank axis
Inventor: LEMMER HELMUT
IPC: F28F21/06
Filed: 1973-10-13
Abstract: In a heat exchanger, particularly a shell and tube single pass cooler, for heat transfer between two fluid streams one of which flows through, and the other round, the tubes between a feed coupling at one end of the tube bundle and a return flow coupling at the other end thereof, all the outer tubes of the tube bundle - viewed in cross section - are arranged in a circle round a central tube, more esp. with the circular profile shell lying along their outer periphery. In particular, the shell is an elastic tube and at least the outer circle of tubes are twisted helically round the central axis of the tube bundle. For a given throughput the heat exchanger takes up less space due to its improved overall coefficient of heat transfer. It is simple to fabricate and assemble and may be made as a module, one or more of which can be incorporated in the cooling system.

Title: Plastics insert for self locking nut - has spline projections on moulded plastics section engaged by bolt threads
IPC: F16B7/08
Filed: 1974-01-29
Abstract: A self locking ring of plastic is built into a threaded nut that allows repeated use without deterioration of performance. The metal nut (8) has a threaded hole (9) running through its length. The top edge of the nut is profiled to provide a secure key for the locking section (7) that is moulded onto the nut. The locking section has a hole near to the nut top surface, that is of a spline type profile (6). The inner diameter of the spline type profile is slightly smaller than the major diameter of the screw thread. When the nut is screwed onto a bolt, the bolt eventually projects into the locking section and the spline type projections are forced against the thread to provide a retaining action.

Title: Shaped fascia strip linking washbasins to walls - is cantilevered to support mirror or lighting units without complicated structural preparations
Inventor: FELDHEGE HEINRICH
IPC: A47K1/08
Filed: 1974-02-01
Abstract: The sectional strip which consists of enamelled steel, plastics etc. is used particularly in bathrooms for fixing up vanity units and has a cantilever projection with a wall member running at right angles to the wall an an adjacent connecting member which runs inclined towards the wall and then down parallel to the wall in the form of a false front.

Title: Rotary combustion engine - with stroke action divided into two different hollow cylinders fitted concentric or in parallel
Inventor: FERRARI EUGEN DR MED
IPC: F01C1/20
Filed: 1974-02-11
Abstract: Otto or diesel engine with suction and compression strokes on one side and combustion and exhaust strokes on the other side taking place in two different either concentric or parallel fitted hollow cylinders. This arrangement largely ensures the elimination of retardation at dead centres as at least one rotary piston is always under combustion pressure. This arrangement also avoids the need of a fly-wheel to overcome dead centres. This engine construction provides a degree of quietness during operation only attained by arranging several cylinders behind each other in the case of conventional engines.
Patent DE-2407971-A1 (DE)
Title: Ski base material - formed from epoxy resin mixed with hollow fibres
Inventor: TIITOLA ANTTI-JUSSI DIPL ING
IPC: A63C5/056
Filed: 1974-02-19
Abstract: A low friction layer made from a mixture of epoxy resin and hollow fibres is bonded to the bottom surface of a ski. After hardening, the layer is ground to make it flat and also to uncover the embedded hollow fibres so that they can function as capillaries. By varying the ratio of epoxy resin to fibres, the characteristic of the layer can be altered to meet the individual requirements of cross country or downhill skiing. The capillary action helps to retain any anti friction substance which is placed onto the epoxy surface. Preferably the composite layer formed is 0.5-1.0 mm thick.

Title: Movable flat strip seal for gas turbine regenerator disc - is located between two machine parts movable relative to one another
Inventor: STUTE MANFRED
IPC: F28D19/04
Filed: 1974-03-20
Abstract: The strip is used to seal relatively opposed chambers at different pressure and temperatures. On the side of the seal body turned away from the slide gap there is a zone extending in the longitudinal direction of the seal which a relatively lower pressure associated with it than in other cases. This relief zone is connected to a point on the slide gap which is at fixed pressure. This connection is effected by a pressure equalisation line extending through the sealing body. The width of the seal is chosen to be so large that the surface pressure caused by pressure loading is significantly less than 200p/cm2 which pressure is related to the service life of the seal.

Title: Restarting cold blast furnaces - using lance comprising coaxial tubes providing oxygen surrounded by fuel stream
Inventor: WELLS WILLIAM
IPC: C21B5/00
Filed: 1974-06-14
Abstract: Blast furnace which has gone cold is restarted by inserting in the iron notch and cinder notch a lance comprising inner and outer tubes with a space between, sealing the lance in each of the notches, injecting an O2 stream into the furnace through the inner tube and injecting the hydrocarbon fuel through the space between the tubes so that the hydrocarbon surrounds the O2 stream. The fuel/O2 ratio is varied so that the burden in the furnace is heated and then the cold iron is oxidised, the exothermic reaction occurs to raise the iron and slag to liquefying temps. and the lances are removed from the notches and the blast restored to the furnace. Restarting is rapid and lances do not tend to burn back whilst inserted in furnace. Tuyeres are left undamaged and break-outs are minimised.
