Title: Moulds from coked resin and metal powder mixtures - for use at high temps
Inventor: RUESTIG REINHOLD
IPC: C22C32/00
Filed: 1969-12-23
Abstract: Moulds with good heat stability, thermal and electrical conductivity, mechanical strength and pressure resistance, suitable for use at 800 - 900 degrees C when used for casting, deep-drawing and esp. vacuum deep-drawing processes are obtd. by mixing 90 - 70% of metal powder (pref. grains of widely differing sizes) with a curable and cokable synthetic resin such as epoxides or epoxidised novalacs or organo-Si cpds. HO-Si(Me)2-o- Si(Me)2-O n-Si(Me)2-OH (n is an integer, Me is methyl)or The formed mould is cured at about 150 degrees C and heated above the decomposition temp. of the resin (700 degrees C) under N2. Nitrogen reacts with the decomposing resin and increases the hardness of the mould. The metal sinters at the same time to form a conductive skeleton. Glass or asbestos fibres or powder may be added to increase the mechanical strength.

Title: Switch locking mechanism with sliding cam - engages switch and is locked or released by vertical shaft with travelling balls
Inventor: HOFFMANN FRITZ
IPC: H01H9/20
Filed: 1973-08-09

Title: Electromagnetic fuel injector valve for compression ignition engines - has pressure restrictor unit with same capacity as needle valve
Inventor: ZIESCHE KURT DIPL-ING DR
IPC: F02M51/06
Filed: 1973-08-28
Abstract: The valve needle is connected with the armature of an electromagnet which when excited raises the valve from its seat against a return spring to allow fuel to flow to a pressure chamber connected to a compensator valve as in 2,210,213, and is now improved by providing a pressure restrictor unit to increase the needle valve closing speed which can be adversely affected by residual magnetism. The restrictor unit consists of a plunger whose swept volume is the same or slightly less than that of the valve needle and moves against the force of a return spring inside a restrictor bore in the fuel flow direction. The valve needle guide diameter is ten times as great as the valve seat opening cross section. The restrictor plunger lift is determined by the spring cover length which has an offset fuel bore whose position serves as a spring support and determines the spring tension.

Title: Sliding camera shutter mechanism - has flash gun release operated by common operating lever
Inventor: ETTISCHER HELMUT
IPC: G03B9/58
Filed: 1974-02-05
Abstract: The shutter comprises a simple, flat profile sliding shutter which is released by a push rod operated by the shutter release button. The same push rod operates the flash gun release which is either a spring loaded inertially fired flash bulb, or a piezo - electric fired bulb. In order to smooth out the vibrations on the camera the amount of travel of the push rod is different for the shutter release than for the operation of the flash gun. The flash gun operation requires a much longer travel of the push rod to provide a better mechanical advantage and a smoother release.

Title: Rapid starting static converter - particularly for standby supplies provides full power with minimum start up time and uses batteries for energy store
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02M7/517
Filed: 1974-10-22
Abstract: The static converter circuit provides its full output power with a correct phase relationship to the supply which it will be replacing in a very short time. During normal supply periods energy is stored to be fed into the load system, and when priming or firing signals are allowed through to the inverter by interruption of the normal supply, the inverter is supplied by some standby d.c. source such as batteries providing both polarities. This ensures that the correct polarity is available at the instant of switching. Switching is by electromechanical relays, thyristors or triacs (Tr1, Tr2), the switching operation being synchronised from sensors in the switching network.
