Patent DE-2324240-A1 (DE)
Title: Thin-walled cast iron bodies - produced under strictly controlled cooling conditions
Inventor: PLATONOW BORIS P
IPC: C22C37/10
Filed: 1973-05-14
Abstract: Complex castings, such as cylinder blocks, are produced by casting ion contg. 3.6 - 3.8 % C, 2.8 - 3.2 % Si, about 0.4 % Mn, and up to 0.01 % Mg, at 1420 - 1450 degrees C; the cooling conditions are chosen depending on the wall thickness of the product in such a manner that the initial cooling rate is 10 - 14 degrees C/sec. By this meyhod, the wall thickness of e.g. a cylinder block can be reduced to 3 mm, whereby the total weight is reduced by 20 - 40 %. The formation of shrinkage voids and pores is avoided without using risers. The amt. of the spheroidisation modifiers is reduced. The casting can be easily worked mechanically.

Title: Fastening clamp for securing fixtures to uneven surfaces - is divided into two sections one rigid one pliable
Inventor: DRUBIG HORST DIPL ING
IPC: F16B5/06
Filed: 1973-09-28
Abstract: The feature if this design of clamp is that its fastening zone is divided into two areas.

The two zones are distinctly separate and in case of a clamp made of sheet metal, a semicircular slot would form the boundary. The active part of the clamp is more rigid and stronger than the passive part of the 2 zones is at different levels. The clamp can be peardrop shaped. The fixing hole in the centre is surrounded by the boundary slot.

Title: Cleaning agent attachment for windscreen wiper - with replaceable water soluble charge and applicator sponge
Inventor: NIXDORF HANS-WILLI
IPC: B60S1/38
Filed: 1974-03-15
Abstract: A plastic container is clipped to one side of the windscreen wiper blade holder by a profiled lip which slots under the securing clips for the blade holder. A special charge is clipped into the open profile holder so that a steady release of cleaning agent drips out of the container when water is applied, the charge being water soluble. A moulded groove under the holder locates a cleaning sponge which is retained by moulded teeth. The cleaning sponge is pressed down onto the windscreen when the wiper blade tilts when wiping in the direction of the sponge, and lifts off the windscreen when the blade tilts the other way on the return wiper.
Patent DE-2416621-A1 (DE)
Title: Markings carrying device - has holes for operating elements and a light guiding plate
Inventor: RIEDEL WOLFGANG
IPC: F21V8/00
Filed: 1974-04-05
Abstract: The plate illuminates the markings when the light is switched on. It has reflecting surfaces which guide the light from a punctiform source to the markings, whose direct illumination is prevented by holes in the light guiding plate, designed itself as the marking carrier. Inclined reflecting mirrored surfaces receive several light rays, and the plate material ensures for these rays conditions for total internal reflection. This plate at least partly surrounds the light source, and the reflecting surfaces are so shaped, that the reflected light is converging and/or diverging.

The membrane is located in front of the outlet of the conveyer and on its axis. The hammer mill has a pivoted inlet flap which acts as a self actuating control on the flow of material to be ground, above this being the space into which the conveyer discharges. The appts. is useful for mixing and blending solid materials, esp. animal feedstuffs, where considerable variations in both compsn. and moisture content can occur. A more uniform prod. is obtd.

Title: Device for walking on water - has valve on float device to lessen suction when lifted
Inventor: SCHROEDER EGON
IPC: B63B34/56
Filed: 1974-07-20

Title: Apparatus for non destructive testing of photographic material - uses scanning wavelengths which pass between photosensitive particles and through support medium
Inventor: GRUENDEL PETER DIPL ING
IPC: G01N21/89
Filed: 1974-08-31
Abstract: A method for non-destructive testing of photographic material uses a scanning wavelength corresponding to the gaps in the sensitivity curve of the sensitising material and the tansmission maximum of the photographically inactive underlayer of the material under test. The radiation applied in a definite way to a moving band of the photographic material is received by conventional photoconductive rod and it is converted into electronic signals which can be continuously compared with reference signals corresponding to the desired characteristics of photographic material which has no flaws in its manufacture. The apparatus is suitable for such a system may include a transparent drum with the photocell mounted inside it.

Title: Quick release closure for pressure vessel - having integral pressure release device and safety mechanism preventing premature release
Inventor: POETZ KARL
IPC: B65D45/32
Filed: 1974-11-27
Abstract: Quick release closure for press. or vacuum vessels with lids and flanges on the lid side has obligatory press. release device built into it. It consists of two semicircular U sections, hinged together at one end, which fit over making surfaces on the flange and lid. The two sections can be bolted together, the hollow bolt used being covered by the press. release device when this is inserted. A coupling piece connected to one section is bolted to the other. The press. release system consists of a hole into the vessel which is sealed by a special bolt screwed through the hollow mounting bolt, with a head of greater dia. Than the mounting bolt. esp. for use with filters. Most quick release closures do include an integral press. release device but often it is possible to break the coupling before all the press. has gone. In this case the lid is explosively ejected with possible damage or injury resulting. The device described prevents removal of the coupling until all press. is released.

Title: Magnetically operated steam shut-off valve - has double coaxial pistons to close value due to internal or external pressure
Inventor: MEYER WALTER
IPC: G21D3/04
Filed: 1975-01-24
Abstract: A stepped piston valve (5) combine with a piston (14) and check valves (27, 28), between inlet (1) and outl (2), with magnetic valve (31) control. When the magnetic valve s shut (31), the valve (5) keeps open and depressured piston (14) (21) seats on a face (22) with volumes (9, 16, 20) under pressure. Opening the magnetic valve (31) depressures volume (16) whilst volumes (9), (20) remain under pressure against check valve (27). Another check valve (28) shuts to a depressured outlet (2) so that the thrust difference on valve (5) holds it shut. Volumes (9, 20) remain pressured against the second check valve (28). The larger piston dia, (7) gives adequate thrust on the seating (6) for closure to inlet (1). When unloaded the valve can be opened by independent pressure at connection (34).
Patent DE-2502975-A1 (DE)
Title: Flagstone for walls and pavements - has triaxial symmetry and alternate equal indentations and projections around its periphery
Inventor: STEINBOCK LOTHAR DIPL PHYS DR
IPC: E01C5/00
Filed: 1975-01-23
Abstract: The alternate indentation and projections around the circumference of the regular hexagonal flagstone are equal in shape and mirror-symmetrical. The axix of symmetry of the indentations and projections coincides with that of the central section. The base angle of the indentation or projection is greater than sixty degrees. The added or subtracted shape is a trapeze, the non-base sides of which are half the length of the base side, so that the flagstone appears to be composed of four regular hexagons. The design allows shear stresses to be collected in such a way that cracks do not propagate through the system.
