Patent DE-2656366-A1 (DE)
Title: Electrode for electrolytic machining of grooved pattern - produced by coating between spiral wires leaving grooves for cathode wires after extn.
Inventor: KOCH HANS DIPL ING
IPC: C25F7/00
Filed: 1976-12-13
Abstract: An electrode for the electrolytic machining of a grooved pattern, e.g. to manufacture the hemispherical recess grooves in a spiral groove ball bearing block, is produced by attaching spiral wires to the outside of the spherical electrode tip. An insulating polymer layer is applied in a thickness of half the diameter of the wires, and the wires are finally extracted from the layer, leaving open grooves. The result is an electrode which is robust and not sensitive to mechanical damage. The manufacturing costs of such electrodes are kept down to an economic level.

Title: Tying clamp for cable bundles - permits tangential or radial fastening of free end and incorporates strip with recessed teeth
Inventor: HOLZMANN HERMANN
IPC: F16L3/233
Filed: 1977-07-16
Abstract: The clamp is intended for bundling together small cables or wires, for example in the internal wiring of a control cubicle. The tie comprise a strip (1) with recessed teeth (3) on the side which will face the cables, and serrations on the opposite side. At one end of the strip is the buckle (2) which is arranged for fastening in two directions. At least two of the teeth (3) engage with the buckle in each fastening position.

Title: Soot removal from furnaces used for fully automatic gas carburising - where limited amt. of air is fed into furnace for slow oxidn. of soot deposited on furnace walls
Inventor: HOFFMANN RUEDIGER DR ING
IPC: C23C8/20
Filed: 1978-09-25
Abstract: Less than the stoichiometric amt. of air required to burn the soot is fed into the furnace while the latter is at 600-900 degrees, esp. 750-850 degrees C, the amt. of air being controlled by measuring a component, esp. O2, in the furnace atmos. During the supply of air, the furnace temp. is increased by max. 200 degrees C., and pref. by ca. 50 degrees C.; and the deposited layer of soot is burnt away. The soot removal process is stopped as soon as an excess of air is present in the furnace atmos. The O2 in the furnace atmos. is pref. measured via a ZrO2-oxygen sensor; and the supply of carburising gas is only stopped after the furnace temp. has fallen to the temp. selected for soot removal, i.e. between 750-850 degrees C. The process of soot removal, is accurately controlled by the ZrO2 sensor.

Title: Diffuse illumination electronic flash - has combination of direct and variable flashes simultaneously fired and mutually compensated
Inventor: TAKEMATSU YOSHIYUKI
IPC: G03B15/05
Filed: 1978-10-24
Abstract: The electronic flash gun attachment is for a camera in which two discharge tubes are used; one (17) on the main gun housing and one (19) on a variable geometry head (12).
