Title: Hydraulic circuit arrangement for motor vehicles - has two slide valves each with control chamber to move slides against spring force
Inventor: LEINEWEBER GUENTER
IPC: F15B1/027
Filed: 1973-10-18
Abstract: Hydraulic circuit arrangement esp. for motor vehicles with a pump line and return line for hydraulic fluid passing to and from a container. The control chamber of one valve is continuously connected with a store and is so designed w.r.t. the spring that it carries over, at an upper store pressure, from its first position into a second position in which it connects the control chamber of the other valve with such a first line that its slide interrupts the hydraulic feed from the pump line to the store by connecting the pump line with the return. The slide of one valve in its second position connects the control pressure chamber of the other valve with the store which is then cut off from the pump line.

Title: Relief-type recording of signals - metal carrier is used as stamped die by modulated laser beam
Inventor: BUETTNER ULRICH
IPC: G11B23/00
Filed: 1974-03-28
Abstract: The modulated laser beam produces at first an etching mask in the photo-sensitive layer on the metal carrier. In the subsequent etching operation, a relief is formed which corresponds to the signals to be stored. The distance of the exposure spot produced in the photo-sensitive layer is chosen, so that during the subsequent etching operation a continuous track run line is produced by under etching in the material of the carrier. The cross-section of a thin photo-sensitive layer is coated on the carrier material to be etched. The carrier material can be, for example, a nickel plate.

Patent DE-2452446-A1 (DE)
Title: Anti-corrosion aluminised coating - for ferrous metals with brazed joints
Inventor: DEAN MICHAEL F
IPC: F01D5/28
Filed: 1974-11-05
Abstract: Prodn. of a thermally diffused corrosion protecting aluminised layer on stainless steel components with brazed joints where the braze material is a non-ferrous alloy at m.pt. 607-1052 degrees C and esp. an alloy based on Cu, Ag, or Au, with m.pt. 635-1010 degrees C, involves protecting the braze from excessive Al penetration by selectively plating it with a 0.005 mm layer of Ni. Selective plating is achieved by chemically depositing Hg on the braze, immersing in aq. HNO3 or CrO3 to remove Hg and passivate the steel, followed by electroless Ni plating which deposits only on the braze. After aluminizing, corrosion protection is further improved with one or more silicate coatings opt. followed by chromate/phosphate treatment. Used for mfg. components, e.g. for turbines, which draw in air and operate in marine conditions. Weakening of brazed joints by excessive penetration of Al is prevented.

Title: Microfilm camera suction plate - holds film strip and suction chamber sealing strip on frame window during exposure
Inventor: WIESSNER MANFRED
IPC: G03B27/32
Filed: 1975-02-15
Abstract: A microfilm camera (7) is fitted with a suction plate (13) to hold a film strip (16). During the exposure process a sealed support of the strip on the frame window is ensured on all sides by a second suction device.
