Title: Drawer guide with rail fixed to furniture frame - has extended integral web on rail forming extra stabilising face
Inventor: BAIER GOETZ E
IPC: A47B88/12
Filed: 1974-09-26
Abstract: The drawer guide comprises a rail attached to the furniture frame and is designed as a double-walled plastics section strip of U-shape cross-section with an integral web extending over most of the length of the strip.

Title: Automatically applied bandage clip - holds bandage in a roll and prevents unravelling
Inventor: STEINER KARL
IPC: A61F15/00
Filed: 1974-11-08
Abstract: The individual bandage clips, usually comprising two hooks joined by an elastic band, are taken from a cartridge strip and fixed in the bandage roll at a predetermined location thus saving on manpower sorting out the clips and fixing them by hand. When the bandages are wound onto rolls on cores an optical or mechanical sensor is used to stop the rotation of the bandage at the right moment and swing the bandage forward, the fastener is then automatically removed from a cartridge strip and fixed into the roll at the correct position over the free end. The cartridge strip moves a step further on and the action is repeated on the next bandage.

Title: Tantalum coating bores of steel tubes e.g. for chromatography - by thermal decompsn. of tantalum chloride in hydrogen
Inventor: STOLZ MANFRED ING GRAD
IPC: C23C16/14
Filed: 1975-05-26
Abstract: Parent patent describes coating the bores of tubular objects with tantalum using chemical vapour deposition in which a current of H2 contg. TaCl5 is drawn through tubes which are zone-heated to a deposition temp. above 600 degrees C. In the addition, several tubes are simultaneously zone-heated by an induction coil, the tubes being arranged symmetrically w.r.t. each other on a concentric circle inside the induction coil. Each Tube is pref. fed with 0.5-1.5 litres H2/minute to which TaCl5 is added, with heating in zones to 900-1050 degrees C by an induction coil travelling at 1-20 mm/minute along the tubes, esp. using 3 mm/minute and 950 degrees C. Method is e.g. used for coating the bores of tubes made of steels V2A or V4A, with Ta for use in liq. and gas chromatography in chemical analysis. The cost of coating is reduced by the simultaneous treatment of several tubes. Attempts to reduce costs by increasing temp. or speed were unsuccessful.

Title: Electric typewriter with clearing mechanism - has type bar drive operated by switching motor on
Inventor: FUTHS GUSTAV
IPC: B41J7/30
Filed: 1976-02-14
Abstract: Electric typewriter has type bars (27) driven by respective drive pawls engageable with a toothed drive shaft (1) in response to depression of a key (49).
