Title: Hover track junction points - has emergency wheel guidance rails formed as elongated tongues above support rails
Inventor: DUELL HANS-JUERGEN
IPC: E01B25/34
Filed: 1975-09-29
Abstract: The junction points unit, with emergency travel guideway, is for use in conjunction with hover vehicles with electro-dynamic support and lateral guiding system, and extensible wheels for which emergency track rails are fitted. The wheels are normally retracted when the vehicle is travelling at high speed. The emergency track rails (4, 5) are mounted in the points above the rails with the support (10) and lateral guidance (8) and forward drive coils (9). They are in the form of elongated tongues, projecting beyond the frog unit (11) in the junction points. This ensures provision of a reliable form locking emergency guidance of the vehicle in the points, without recourse to crossover points between emergency track rails and vehicle magnets.

Title: Monitor system for status of relay group - uses cable break or switching of one or more relays to trigger alarm
Inventor: SCHENK RUDOLF DIPL ING
IPC: G08B23/00
Filed: 1975-10-11
Abstract: The automatic monitoring system provides a check on a number of relay states, such sa may be encountered in a fire alarm system. Either a d.c. or a.c. voltage source (1) may be connected across the relays (K1, K2,.. Kn) that are to be monitored. A detector in display element (3) is held in the active state provided that all relays are open. The detector drops out and an alarm is triggered if any relay closes. In this case the source is short circuited across the series resistor (2). The circuit will also trigger the alarm in the event of a source failure or cable break.

Title: Oily oral solns. of unsaturated phospholipids - contg. phospholipid and bile acid salt addition cpds. in mixts. of vegetable oils and partial glycerides
Inventor: BETZING HANS DR
IPC: A61K47/28
Filed: 1975-12-16
Abstract: New medicinal prepns. for oral administration based on oily solns. of phospholipids with a high content of essential fatty acids contain the phospholipids in the form of a complex addition cpd. with one or more alkali salts of bile acids, dissolved in a mixt. of vegetable oils and partial glycerides of such oils which are rich in mono- or poly-unsatd. fatty acids.

Title: Bake-oven with closed ring steam heating tubes - having counter current flow of combustion gases and the water in the tubes
Inventor: BRUNKLAUS JOHAN HENRI ANTONIUS
IPC: A21B1/08
Filed: 1976-02-10
Abstract: In a bake oven having >=1 baking chambers with heating by closed ring-type tubes partly filled with water, the lowest part of each ring being inclined to the horizontal, the hot gases from a gas or oil burner flow in countercurrent to the water in the tubes and, after heating the tubes, pref. pass into a space in which >=1 steam generator is installed. The use of countercurrent flow is thermally more efficient and the useful heat prodn. is greater, while more uniform heat loading of the tubes is achieved. The use of masonry is superfluous and the heat capacity, and therefore heating up time of the oven, is reduced.
Patent DE-2617151-A1 (DE)
Title: Railway goods wagon end walls - has connection to underframe with elastic links permitting outward swing under impact to set angle

It is designed to improve the energy absorbent capacity of these, without disturbing the overall structural layout. The end walls are elastically connected to the underframe in such a way that impacts, or similar loadings, result in them swinging away from the loading area, up to a predetermined angle. Elastic connection can be provided by a torsion element, helical spring or lengthways stressable spring element. Each end wall's posts may be interconnected.
Patent DE-2619968-A1 (DE)
Title: Distributed burglar alarm network with sabotage detection - triggers alarm if alarm circuits are broken but not if mains failure occurs
Inventor: HIRRLINGER KLAUS DIPL ING
IPC: G08B29/08
Filed: 1976-05-06
Abstract: The distributed burglar alarm network supplied by the alternating current mains has an anti sabotage feature which automatically triggers and alarm if the supply circuits are broken, but not if a mains failure occurs. A number of detector elements on different parallel monitor lines feed a central evaluation unit comprising bridge type impedance alteration detection circuits. When a detector element impedance changes an audio or visual alarm is triggered by the central evaluation unti multiplexing circuit. These alarms are themselves monitored by a bridge type circuit so that interference with their supply line itself produce an alarm, but in parallel with their supply line is a mains operated relay contact which disables this sequence when a mains failure occurs.

The side edges of the foil sheet are joined together by longitudinal welded seams. The walls and both sides of the fold have slots (15) forming a hand grip for the bag.
Patent DE-2633591-A1 (DE)
Title: Frost protection for young plants - using gas or oil combustion with white reflector below radiator
Inventor: BERGER CORNELIA
IPC: F24C1/12
Filed: 1976-07-27
Abstract: The radiation heating is suspended or set up on a linkage for protecting growing vines or fruit against frost damage, the radiation being provided by the combustion of oil or gas. The radiator has its radiation surfaces pointing to the plants to be protected. It is heated so much that with increasing temperature, the specific radiation of the radiator rises so far until the radiator transmits electromagnetic waves whose radiation maximum lies in the infra-red spectrum. A radiation-receiving "white" reflector reflects the radiation onto the radiator, raises its temperature and its specific radiation and thus simultaneously increases its radiation output.

Title: Extractor using reciprocating fork - to remove stamped workpieces and scrap cuttings from a sheet metal stamping press
IPC: B21D45/04
Filed: 1976-09-29
Abstract: Extractor, for removing workpieces from a press, using a reciprocating fork moving in a horizontal direction, and synchronised with the movement of the press ram. During the forward stroke of the fork it moves under the workpiece, and holds the latter via suction pads, magnets or projections; on the under side of the fork-prongs are magnets which pick up the scrap pieces of metal sheet formed during the stamping of the workpiece. During the reverse stroke of the extractor, work cylinders lift fingers against the force of springs, so the workpiece is raised and is picked up by a magnetic conveyor belt; simultaneously, the magnets fitted on the bottom of the prongs are switched off so the scrap falls into a bin. The magnetic conveyor carries the workpieces to a stacking trolley. Strip is fed into a press for the stamping of workpieces, which are then grnetly removed from the press without damage, and also removing th scrap.

Title: Liq. alkyd resin gelation reversal - by addn. of steam to the resin at elevated temp.
Inventor: CALLAHAN WILLIAM BRYCE
IPC: C08G63/48
Filed: 1977-05-06
Abstract: A liq. alkyd resin (obtd. by esterifying a polybasic acid with a polyhydric alcohol and removing formed water) undergoing gelation is treated with >=0.02, prf. 0.05-3 wt.%, based on the resin, steam per min. at 200-275 degrees C. to reverse the gelation. Resin is used in paints and varnishes for coating wood, metals, plastics and polymer-reinforced fibreglass. Properties of the obtd. resin are very similar to those of a resin obtd. without any gelation. In an example, a soya bean oil/heat-bodied soya bean oil/pentaerythritol/phthalic anhydride alkyd resin undergoing gelation at 210 degrees C is treated with low press steam at 100 degrees C, at a ratio of 0.05-0.1 wt.% per min., based on the resin, for 20-25 mins. to reverse the gelation process.

Title: Hot run=off wort cooling method - by passing through two cones set over outflow valve opening in brewing vat without intermediate vessel
Inventor: HOEHN THEO
IPC: C12C7/26
Filed: 1977-06-02
Abstract: A new method of cooling the hot run-off wort in a brewery direct from the brewing copper and without any intermediate vessel prevents the darkening and oxidn. and enables the hot sediment to be removed completely, with a minimum of heat losses. A cone is first set on top of the outlet of the brewing vat outflow valve, with a strainer, and a larger cone over it. After an interval of 15-30 min. after the wort boiling the cooling can begin, using the vat scavenging pump for the circulation. The first frew hectolitres of wort are run into a container and the plate cooler is then inserted. After 20-30 min. the outer cone is drawn and the wort draw-off continues through the inner cone with the strainer.
