Title: Extension fitting for televisions with telescopic rails - has locking member ensuring correct extension sequence of rails preventing undue strain
Inventor: KNEILE KARL
IPC: A47B88/493
Filed: 1974-11-06
Abstract: The extension fitting comprises a console bracket fixed to the supporting furniture and a support mounted to slide in and out over lateral extension rails horizontally relative to the console bracket. A locking member is on the support so that when the support rails mounted on the television support are in the retracted position relative to the intermediate rail the locking member engages in a locking counter member mounted on the intermediate rail but is automatically disengaged when the latter is in the extended position relative to the console bracket rail. During extension the intermediate rail is held firm relative to the television support and the television rails until they have reached their extended position relative to the console rails. Only then can the television rails be extended out.

Title: Epitaxial silicon films prodn on sapphire substrate - by chemical vapour deposition from gas mixt contg dichlorosilane
Inventor: DRUMINSKI MANFRED DIPL CHEM DR
IPC: C30B25/02
Filed: 1974-12-02
Abstract: In the prodn. of epitaxial Si films on a sapphire substrate by chemical vapour deposition, a gas mixt. of SiH2Cl and another gas (I) is used, deposition is carried out at rates of 0.2-10 mu/min at 900-1100 degrees C and the sapphire substrate is pretreated, pref. by polishing, so that it is free from damage. The SiH2Cl2-H2 system gives films with as good or better quality than those from the SiH4-H2 system and also allows the use of lower deposition temps. and higher growth rates. SiH2Cl2 can also be placed as liquid in climatised rooms without thermostating, since its vapour pressure is sufficiently high. Very many experiments can be carried out with one flask, without time-consuming flask changes.

Title: Piston type air gun with spring tensioning system - has safety device to absorb mainspring tension unless released
Inventor: RESUGGAN HAROLD FREDERICK
IPC: F41B11/647
Filed: 1975-06-16
Abstract: A piston type air gun has the tensioning device constructed as a system acting on one side of the piston which tends to try to achieve a discharged position and a safety device on which the actuating member loosely rests on the safety position so that the tensioning system is pressed away from the piston in this position.
