Title: Fixing plug for concrete, masonry or other hard materials - produces expansion at additional position for firm anchoring in bore
Inventor: PRUETER HEINZ GUENTER
IPC: F16B13/06
Filed: 1975-02-08
Abstract: A plug (1) has a slotted lower end having a cylindrically bored length followed by a reducing taper (1a) blending with the smaller diameter parallel drilling of the remaining length. The cone (4) has a circumferential rib (7a) whose diamter is less than the maximum diameter of the conical section. After insertion of the lead-in end of the cone into the end of the plug, and of the plug into its hole, tightening of the bolt into the tapping (10) of the cone draws the latter into the plug, whose tapered section is plastically enlarged by the rib of the cone in addition to expansion of the extreme end by the cone proper. alternatively, the cone may have two stages of tapering separated by a parallel section.

Title: Purifcn. of water by means of ozone - easily handled and installed appliance transfers heat to product water
Inventor: BACHHOFER BRUNO
IPC: C02F1/76
Filed: 1975-03-15
Abstract: Water, esp. bath water, is purified by means of an ozone producer, the outer surface of which can be adequately cooled, built into a vessel through which the water passes; a mixer with an injection head being secured to the ozone producer at the point at which the water feed pipe opens into the vessel. The ozone producer is formed by solid, highly heat conductive rings acting as the outer electrodes; circular discs of a ceramic material as the dielectric, and thin circular discs forming the inner electrodes. The gaps between the dielectric discs and the inner electrodes are arranged to form discharge chambers through which the air flows alternately radially inwards and radially outwards. The spacing of the electrodes relatively to the discs is maintained by spacer slugs of an elastomer, and the discs are centralised by means of plugs and sockets. On one end face of the ozone producer; there is a high tension insulating socket with a gas feed connection whilst on the other, the injection head is fitted. A highly integrated and complete installation in a small compass. Works reliably and with little maintenance. Gives a high output of ozone.

Title: Swimming pool water sterilizing plant - with flocculant or oxidizing agent injection to reaction space before equalizing or filter space
Inventor: KRETZSCHMAR WOLFGANG DIPL ING
IPC: C02F1/78
Filed: 1975-05-07
Abstract: The water in swimming pools is purified and sterilized in a concrete container which is divided by a partition into an inlet shaft where the flocculants and oxidizing media are injected, and aq equalization tank. The bottom of the latter contains the two-layer filters (activated carbon and quartz gravel). The outlet is directed to a second injection point for a halogen before the water is returned to the swimming pool. This makes any growth of bacteria or other organisms in the equalization tank impossible without necessitating excessive additions of halogen. A better release of the gas from the water is also achieved. Ozone corrosion is eliminated.

Title: Chemical yarn winding machine ensuring uniform package pressure - has pneumatic hydraulic circuit lifting and lowering carriage
Inventor: LENK ERICH DR ING
IPC: B65H54/52
Filed: 1975-07-18
Abstract: A winding arrangement for yarn packages has a carriage moved by pneumatic cylindrs, which supports the traversing and contact rollers. The latter is maintained constantly in contact with the surface of the yarn package which rotates in bearings outside the carriage. The carriage is linked to a hydraulic cylinder working contrarily to the pneumatic cylinders which is energised by a sensing device for the yarn package dia. This sensing device is formed by a support frame which moves relatively to the carriage with very little friction and carries the contact roller at least. Avoids the stick-slip effect of pneumatically operated winding machines and prevents the development of irregularities in the package diameter setting up vibration in the carriage.

Title: Direction finding aerial arrangement - has lead-outs with different polarizations combined and taken into discrete multiplexer or diplexer
Inventor: KURZ GEORG
IPC: H01Q21/24
Filed: 1975-08-06
Abstract: An aerial arrangement for direction finding systems with broad-band reception, uses two or more aerials wit negligible overlapping of the frequency bands to completely cover the required frequency range. To avoid disruptive interference, the aerials can be run in tow isolated or decoupled polarizations, with one output or lead-out for each of the two polarizations. Each output or lead-out of each aerial is connected to a separate multiplexer or diplexer, when only two aerials are used in the arrangement. With aerials whose frequency bands overlap one another, the outputs or lead-outs carrying different polarizations are combined in one and the same multiplexer or diplexer.

Title: Compaction of aerated powder in air impermeable container - uses centrifuge to which several containers are attached
Inventor: ROSEWICZ HORST DIPL CHEM DR
IPC: B65B1/20
Filed: 1975-10-04
Abstract: The appts. is for the compaction of aerated powders in a container impermeable to air and uses light packaging (e.g. thin-walled polyethylene containers or corrugated paper cartons with glued-in polyethylene sacks) without a cover and avoiding the use of compressed air to compact the aerated powder. In order to achieve this is centrifuge is employed with a vertical hub and radially extending horizontal arms on whose ends the packages are located. The hub shaft of the centrifuge is powered by a motor and has a brake. The centrifuge arms have a hinge in them so that the arm ends hang downwards when the machine is at rest.

Title: Component size consistency measurement - by using several photodiodes and reference diodes to measure shadows of components in light cone
Inventor: CORDT WERNER ING GRAD
IPC: G01B11/245
Filed: 1976-03-30
Abstract: A projector is used in whose light cone the opaque components are placed, so that their shadows can be compared with a standard pattern. Photodiodes are placed at measurement points at the shadow edge. When component dimensions are correct, the photodiodes are only partly illuminated. Output signals so obtained are stored. When tested components are measured, output signals are compared with the stored nominal signals. Signals from opposite points are compared with each other and if necessary equalised. A faulty signal is delivered when signals deviate from standard signals and/or the component is rejected. Further reference diodes (R2-R5) are provided on the illuminated surface in addition to an existing reference diode (Rd1) which is always illuminated during component (A) measurement, and measures max. illumination of the photodiodes (Ra, Rb).
