Title: Hazard warning light switch - responds automatically to shock pulses from various directions using spring loaded ball in tapered depression
Inventor: BADORREK WERNER
IPC: B60Q1/52
Filed: 1977-01-19
Abstract: The hazard warning light switch consists of a peg holding a ball (2) in a tapered boring. Pressure is applied to the peg by a spring contact. The ball sensitivity is dependant upon the boring angle and the spring pressure which is adjustable. The ball responds to shock impulses by moving away from the retaining peg allowing the contacts to close and excite a warning lamp blinker relay switch. The retaining peg can be moved by a manual switch. In an alternative design, the ball is able to roll back into its original rest position after responding to a shock impulse. The ball normally rests in a tapered boring and closes a contact switch by its own weight. The contact switch excites a blinker lamp relay. A two-way manual switch is able to actuate the blinker relay and a control lamp directly and at the same time interrupt the relay automatic feed.
Patent DE-2702489-A1 (DE)
Inventor: GERBERT HEINZ DIPL ING
IPC: F24D19/10
Filed: 1977-01-21
Abstract: The method serves for the automatic optimisation of the operating point of a heating device, in particular of a heat pump, in which the heat energy of the heating medium (7) flowing through a consumer (9) in the circuit is drawn mainly from a natural primary energy carrier (5) by undercooling in an evaporator (1) by means of an intermediate medium (6) flowing in the circuit. The evaporated intermediate medium (6) containing the evaporation heat is brought to a higher heat content by the supply of auxiliary energy and subsequently the increased heat energy of the intermediate medium (6) is delivered to the heating medium (7) serving as secondary energy carrier by liquefaction. In this case, for controlling the auxiliary-energy supply to the intermediate medium (6), the maximum permitted liquefaction pressure or the maximum permitted liquefaction temperature of a compressor (2) are changed or the volume flow of the heating medium through a liquefier (3) is varied, and in particular via the operating time of the compressor (2). <IMAGE>

Title: Cooler guide for moulding belt in continuous casting - has surface formed by dishes with high pressure nozzles
Inventor: LAUENER WILHELM FRIEDRICH
IPC: B22D11/06
Filed: 1977-06-29
Abstract: The running moulding belt in an installation for casting continuous metal ingots, is cooled and guided by directing a cooling fluid through a large number of nozzles towards the face of the belt turned away from the casting chamber. The jets, under high pressure, open into separate dishes, the rims of which are turned towards the belt, and the flow is adjusted so that the coolant fills the dishes and the space between them and the belt completely. The cooling fluid then flows between the rims of the dishes and the belt to be drained off at low pressure. The outlet cross-section from each dish is determined by spacing between the moulding belt and the rim of the dish. In each dish therefore, a hydrostatic pressure acting on the belt is developed, the degree of which depends upon the spacing mentioned. This pressure together with the low pressure prevailing outside the dishes maintains the moulding belt automatically at a practically constant spacing from the rim of each dish. The moulding belt is thus held in the zone of the casting chamber without being retarded and at the same time is guided positively.
