Title: Milling machine infinitely variable gearing - has axially slidable gear coupling for direct or lay shaft drive
Inventor: CLOOS ERNST DR ING
IPC: F16H37/02
Filed: 1975-02-04
Abstract: The infinitely variable gearing for milling machines has gearing driving an input shaft selectively connectable to a coaxial output shaft either directly or through a lay shaft, by an axially slidable gear coupling. In direct drive an internally toothed ring of the coupling engages a drive gear fast on the input shaft to connect latter to the output shaft.

Title: Rectangular-section glass pipe for solar cell - is for water heating system with low feed temp. and with increased efficiency
Inventor: NIEMANN WERNER
IPC: F24J2/04
Filed: 1975-07-31
Abstract: Rectangular-section glass pipe is for conducting water in a solar cell and has grooves in its outer surface which receive a PTC resistance wire (5) in positive-locking relationship and which allow thermal expansion. The resistance wire forms part of a circuit for heating the surface of the glass pipe (1) in proportion to the outdoor temp. and thus equalise heat losses of the circulating water. A filter (6) may be used which allows passage of light radiation but reflects the heat radiation generated by the resistance wire. The power required to operate the solar cell may be obtained by using natural energy sources e.g. a wind-powered generator. By altering the circuit, both solar energy and the energy from natural sources converted to electrical energy can be supplied to the transport and storage medium e.g. water.

Title: Open-end spinning rotor brake - has a spring to exert the braking pressure on opening the rotor housing
Inventor: STAHLECKER FRITZ
IPC: D01H4/30
Filed: 1976-05-20
Abstract: The braking system for the rotor shaft of an open-end spinning station, where there are a number of such stations forming the spinning assembly, is triggered by the opening of the rotor housing in a pivoting action away from the housing contg. the sliver feed and fibre sepn. mechanism. The rotor shaft of each spinning station is mounted in the wedge gap formed by supporting rollers, for which there is a common bearing pedestal in the rotor housing. A stub bearing is fitted to the end of the rotor shaft. The holding brake in the wedge space has a spring to apply the braking pressure, and an operating lever linkage which holds the brake in the disengaged position when the closed rotor housing bears against a limit stop on the feed housing and the spinning station is in its normal operating condition. The brake is applied immediately if the housing is opened, and the braking action is controlled by the adjustment of the braking spring, independently of the operation of the spinning unit components.

Patent DE-2624392-A1 (DE)
Title: Water recovery from the atmosphere - esp. in tropical climates, by adsorption during the night and desorption during the day using silica gel as adsorbent
Inventor: GROTH WILHELM PROF DR
IPC: E03B3/28
Filed: 1976-05-31
Abstract: The process involves the adsorption of the cool night air and using the hotter daytime air to desorb the thus stored water. Night air is passed through a packing of stones to cool it and then through a layer of 8-12 mm silica gel spheroids which have an adsorption range of 0-20 degrees C and a desorption range of 25-70 degrees C. During the day the process is reversed so that the desorbed moisture condenses on the stone packing whence it may be recovered. The process affords large yields of water (both for drinking and for irrigation) without requiring large amts. of external energy.

Title: Inert gas generation from exhaust gas - by controlling fuel-gas ratio to achieve the required compsn.
Inventor: JAEGER HEINZ
IPC: B01J19/14
Filed: 1976-07-30
Abstract: The operation of an internal combustion engine is controlled, by adjustment of the fuel-gas ratio, so that the exhaust gas has a compsn. suitable for use as inert gas. An internal combustion engine e.g. diesel or Wankel, single or multi-cylinder, is coupled to an electrical generator which supplies e.g. the continuous load imposed by compressors, pumps, fans etc in a metallurgical works. This load is sepd. from the incoming grid supply. The motor is powered by a fuel-gas mixing whose rate is adjusted automatically to give the desired rotational speed as measured by a tachometer. The exhaust gas is analysed, and the hydrogen and oxygen contents are compared with the desired values. Deviations cause automatic adjustment of the fuel supply to be made, and excessive values give alarm. Used for the prodn. of inert or blanket gas partic. for use in metallurgical operations. Method gives low-cost prodn. on site.

Title: Semiconductor chip photo-varnish spreading - uses high speed rotation of chip to distribute varnish placed at chip centre
Inventor: POTYKA SIEGFRIED DIPL ING
IPC: G03F7/16
Filed: 1976-08-18
Abstract: At first a blob of the photo varnish composition is applied at the centre of the chip. After the blob has been applied, the chip is rotated at a speed sufficient to distribute the varnish evenly on the chip. The speed at which the chip is rotated is then increased, so that a part of the varnish is thrown away, leaving a thin uniform layer of the varnish on the semiconductor chip. After the varnish has dried, then a pattern may be projected onto the chip followed by etching.
