Title: Limit switching system for cable winch - uses winch-driven potentiometer to indicate distance travelled for suspended studio lights
IPC: F21V21/16
Filed: 1977-10-07
Abstract: The limit switching system, for cable winch for suspended studio lights, has an angle encoder coupled to the winch and coding the latter angle for comparison with a reference. A comparator controls a relay whose contacts break the supply circuit of an electric motor driving the winch. The angle encoder is formed by a potentiometer, whose slider is driven by the winch and whose resistance is therefore proportional to the winch angle of rotation.

Patent DE-2751222-A1 (DE)
Inventor: CORTI CHRISTOPHER W DR
IPC: B01J3/00
Filed: 1977-11-16
Abstract: The high-temperature lubricant, for the hot forming of metallic materials, which is pulverulent at normal temperature and is based on boron nitride and at least one further oxygen-containing boron compound, is capable of forming a viscous, vitreous coherent coating (4) at working temperature in which boron nitride particles (5) are incorporated. The coating is distinguished by good wettability and high adhesive strength to the metal surface (2) and can be applied at working temperature either to the tool (7, 8) or to the workpiece (6) to be deformed or to both bodies simultaneously or one after the other without interruption of operations or intermediate cooling. The viscous or liquid phase (4) can also be applied alone first, whereupon, in a further process step, the boron nitride (5) is sprayed on and incorporated into the vitreous layer. For the production of the vitreous phase, boric acid, boron oxide, boron silicate glass and borax are suitable. The lubricant can be used especially in isothermal thermoforming, above all in the forging of titanium alloys, nickel alloys and iron alloys and is chemically inert with respect to the metallic materials coming into contact with it. <IMAGE>

Title: Bonded insulating element - with additional mechanical fixture by=pass through pins
Inventor: RECKNAGEL ARNO
IPC: B65D90/06
Filed: 1978-03-23
Abstract: Insulating elements for adhesive bonding to the surfaces to be lagged are used, eg. for tanks contg. liquefied gases at low temp. on board ship. The prefabricated panels of insulating material have one surface coated by an adhesive film. Pins are passed through the panels in a regular pattern and have a thin circular disc on the adhesive side.

Title: Remote control signal generator - acts as safety switch for machinery by keeping on-switch closed only as long as person emits sound
Inventor: SCHMITT REIMUND
IPC: G08C23/02
Filed: 1978-05-29
Abstract: The remote control signal generator switches a machine's drive on and off and has a microphone connected to a switch. The operator or another person emits sound, e.g. whistles, and the switch closes and remains so only as long as the sound persists. A frequency analyser is located between the microphone and the switch and ensures that the switch operates at only one frequency. Several such analysers may be connected in parallel with their outputs connected to AND gates so that the device responds to a given mix of frequencies. The microphone may also trigger the release of a radio control signal.

Title: Mixing funnel for adding granular material to molten metal - esp. for adding ferrosilicon:magnesium to iron when mfg. nodular cast iron
IPC: C21C7/00
Filed: 1978-08-26
Abstract: Appts. consists of an inclined gutter via which the molten metal flows a tangentially into the pot-shaped top of the mixing funnel, which has a base contg. an outlet hole to the funnel stem which forms a mixing tube.

Title: capacitor level sensor with dielectric constant compensation - has air and fluid filled compensation and measurement capacitors
Inventor: JUNG WILHELM DIPL PHYS
IPC: G01F23/26
Filed: 1978-12-02
Abstract: A capacitive level meter has a first measurement capacitor immersed in the fluid measured, an oscillator producing an electrical output corresp. to the fluid level, and a compensation circuit for different fluid dielectric constants. It gives extremely accurate level indications yet is very economical to produce. Two compensation capacitors of equal capacitance have the medium and air as dielectric respectively. A second measurement capacitor has the same capacitance as the first measurement capacitor when it is completely surrounded by air as the dielectric. The fluid height is the ratio of the second compensation and measurement capacitances multiplied by the ratio of the differences between the measurement and compensation capacitances. The capacitances are measured by charging them and then measuring the discharge time using pulsed signals.
