Title: Magnetic beacon for cars - is roof-mounted in case of car breakdown due to electrical failure
IPC: E01F9/012
Filed: 1974-11-06

Title: Selective electroplating small parts esp. reeds for reed relays - where only tip of reed is immersed in the electrolyte
IPC: C25D5/08
Filed: 1975-02-20
Abstract: Improved method for obtaining electroplated deposits, esp. of previous metals on small surfaces. The novelty is that a precise zone of the substrates is subjected to the impact of a wave of liq. electrolyte which flows on an inclined slope. The thickness of the liq. wave is pref. controlled by an injector nozzle or spout, or by an inclined slope or a combination of both. Alternatively, the liq. wave may be obtd. using an electrolyte flowing out of an upper reservoir. The inclined slope may be smooth or provided with profiles determining the shape of the wave. Electroplating any industrial part, esp. spring contacts for relays, e.g. the deposition of precious metals on reeds for reed relays. The deposit is restricted to a precise zone of the substrate without the need to use any type of mask.

Title: Membrane type metering pump - has thich elastic membrane forced into working chamber on pumping stroke(NL-9.3.76)
Inventor: WEBER HELMUT
IPC: F04B43/04
Filed: 1975-09-08
Abstract: The pump is worked by an electromagnet (1) which displaces a plunger (3) to the end of which is attached a relatively thick deformable membrane (4). The working chamber (5) is annular and on the pumping stroke the membrane is forced down into this being deformed in the process. When the magnetic force is released the elasticity of the membrane returns it to its starting position and provides the suction stroke of the pump. Liquid enters through a central inlet non return valve (7) with a disc (8) covering a number of inlet openings (9, 10) and leaves through a discharge valve (6). The construction enables more accurate metering than a pump with a thin membrane which is liable to permanent distortion.

Title: Reciprocating vacuum pump to degas desalinated water - is hydraulically driven by water draining from high level condenser
IPC: C02F1/04
Filed: 1975-10-30
Abstract: The desalination plant condenser drains into a high level collecting tank which gravity feeds a high column of water. At the lower end of the column the water is used to drive a reciprocating pump piston. The suction side of the pump is piped to the head space in the collecting tank. The pump piston rod is pref. coupled to a driving piston rod in a hydraulic power cylinder fed with high pressure water from a reserving at the base of the water column. The hydraulic cylinder is pref. single acting with spring return stroke. The power cylinder and pump inlet and outlet valves are fitted with sequencing valve gear so that the pumping cycle repeats automatically as long as water is supplied to the cylinder. Design provides economy in installation and operation since the pumping system is continuously powered by a head of water and no electric supply is required.

Title: Producing radiation line focus on moving workpiece - esp. for automatically welding layered or tubular synthetic film
IPC: B26D1/04
Filed: 1976-12-28
Abstract: A device for treating a workpiece by moving focused radiation across it, e.g. in the welding of a synthetic film, includes an optical system for the prodn. of a line focus of a radiation beam on the moving workpiece, so that the direction of the line focus is at right angles to the direction of motion of the workpiece. It includes also means of deflecting the focussed beam over the workpiece in a direction which has a component in the direction of motion of the }workpiece of such a dimension that the actual motion of the line focus of the radiation beam relatively to the workpiece takes place in a straight line along the line focus. The optical system consists of a cylindrical focussing leans, a spherical intermediate focussing lens and a projecting lens. The deflectors consists of a mirror positioned between the intermediate lens and the projector, the alignment of which, relatively to the cylindrical lens can be altered, so as to alter the direction of the deflected track of the focussed radiation. Moving workpieces can be treated with a line focus of a radiation beam which moves at the same speed as the workpiece and remains parallel to its starting position. When a band or tube of high pressure polyethylene e.g. has to be cut and welded, a laser, for pref. a CO2-infrared laser is used. More than one line focus can be produced if required by means of a Fresnel bi-prism, and in the prodn. of bottles and sheaths from two layers of film, three line-foci may be produced.

Title: Ultrasonic emitter scaring off small animals - has central frequency very low frequency and square signal generators with diode to round off signal flanks
IPC: A01M29/18
Filed: 1976-12-28
Abstract: The ultrasonic emitter scares off small animals and particularly rodents, and allows all animals to be affected in successive chronological times dependent on the volume of their cervical cavity. It causes an intolerable noise and disturbs their means of communication. It incorporates central frequency, very low frequency and square signal generators, a transistor driving the power amplifier, an ultrasonic transmitter, a rectified voltage regulator, and a starting signal system. The very low frequency single-junction generator can oscillate at 2 HZ, supplying saw teeth transformed into triangular signals modulating the central generator. The square signal generator, which is a cross-connected multivibrator, drives the generator so as to chop its signal at 13 HZ. The diode rounds off the edges of the signal flanks to avoid audible shocks.

Title: Printing relief patterns in soft clay during ceramic mfr. - using a roller with flexible typographic design
IPC: C04B41/45
Filed: 1977-03-18
Abstract: Patterns are impressed into soft clay during mfr. of ceramic articles using a typographic plate. The pattern is formed on a printing plate or roller, and has hollows and reliefs, the shape being obtd. by photogravure. The plate may have a number of different patterns situated at different levels. The pattern may be reproduced continuously on an advancing strip of clay be means of a roller or continually by means of a flat plate and a press.
