Title: Three-wire two=way junction circuit between exchanges - uses both loop calling and C-wire signalling to changeover from incoming to out-going selectors and vice=versa
Inventor: RICHTER REINHARD ING GRAD
IPC: H04Q3/00
Filed: 1980-10-22
Abstract: A three wire junction connection between a public exchange and a 03BX reduces equipment costs in the exchange, provides a more secure signalling system. The exchange responds to a loop on the a and b wires of the junction circuit. Relay operation then connects the a and b wires through to an exchange incoming selector. At the end of the call the loop is removed from the junction. To signal from exchange to PABX the exchange extends a condition of the c wire to the PABX and the a and b wires are switched to the output of an exchange selector. A continuous voltage is fed from the PABX to the exchange over the c wire in order to hold a relay. If the relay drops out the circuit is busy.

Patent DE-3101148-A1 (DE)
Title: Cast concrete element
Inventor: DURACH RUDOLF
IPC: E01C5/00
Filed: 1981-01-16
Abstract: A hollow concrete element is made up exclusively of circular/cylindrical casing portions, of which at least one is curved convexly and at least a further one is curved concavely. All convex and concave casing portions have the same curvature, with the result that they can be alternately fitted precisely one into the other, a positively locking engagement thus being possible. Two convex portions can be combined with two concave portions in the same way as three convex portions with one concave portion or three concave portions with one convex portion. The novel hollow concrete element is used principally for forming retaining walls, walls, terraces, staircases, seating arrangements and plant arrangements. The novel cast concrete element does not entail any higher production costs, but, owing to its capacity for interconnection, it makes it possible to form novel, visually pleasing combinations, the high stability resulting from the positively locking connection being of great advantage, in particular, in the case of relatively high structures. <IMAGE>

Title: Device for mechanically separating mixtures of liquids and solids
Inventor: KOCH KLAUS DIPL PHYS
IPC: B30B9/12
Filed: 1981-02-07
Abstract: A device for mechanically separating mixtures of liquids and solids, e.g. sludge from paper factories, comminuted beet, beet leaves, oil seed or the like is disclosed by means of which a liquid which has already been pressed out but which still contains relatively small proportions of solids can once again be filtered and/or pressed out in a continuous fashion and without using an additional device. To this end, the liquid which has been pressed out, still contains relatively small proportions of solids and has been pressed out via a network of channels inside the worm, is filtered and pumped back into the extrusion chamber, into a region in which the mixture of liquids and solids has already had the liquid pressed out of it to a very substantial extent. The mixture from which almost all the liquid has been pressed out acts in this region as a compound which encourages further filtration of the returned viscous mixture, and therefore finally ensures that all the mixtures of liquids and solids have almost all the liquid pressed out of them.

Title: Process and device for saving compressed air, in particular in thermoforming machines
Inventor: REBMANN MANFRED
IPC: F15B11/064
Filed: 1981-03-26
Abstract: The invention proposes a process and devices for carrying out the process for saving compressed air, in particular in thermoforming machines, in which compressed air is used for pressurising the mould (14). The compressed air which was hitherto bled into the atmosphere after carrying out the moulding operation is now bled away in stages. This is carried out in such a manner that, via a suitable valve control and corresponding lines, some of the compressed air still present after the moulding operation is stored and subsequently fed to various other consumers. A relatively high energy saving, based on the entire thermoforming machine, can be achieved by this measure. <IMAGE>

Title: Lighting device for attachment inside a rotatable merchandise stand
Inventor: HUEBER ROLF
IPC: A47F5/02
Filed: 1981-10-09
Abstract: An optimum merchandise display in the shop requires a conspicuous, clear arrangement and space-saving storage with good merchandise access. Rotatable merchandise stands achieve a higher attention value for themselves as a unit and for the merchandise itself due to integrated lighting of the merchandise planes. A centrally axially arranged, non-rotatable, cylindrical light source (e.g. fluorescent lamp) around which rotatable shelf planes are located in a circle constitutes a cost-effective, energy-saving, technical solution to the object according to the invention since a separate light source is not required for each plane and the installation and energy costs are thus lower. Such rotatable, illuminated merchandise stands are particularly suitable for valuable jewellery and optical items which have an attractive effect when illuminated by reflection, as well as for heat-sensitive, perishable merchandise which is sold more quickly due to its display. <IMAGE>
