Patent DE-2601094-A1 (DE)
Title: Plastic lined pressurised water tank - has porous plastics blanket vacuum formed to tank metal beneath plastics lining
IPC: B65D90/507
Filed: 1976-01-14
Abstract: The pressurised water sprinkler tank anti-corrosion lining is shaped around the connection joints for complete sealing. Between the tank shell and an innermost fluid contacting lining, a porous plastic blanket, under slight vacuum, protects from rough metallic surfacing, with a blanket to inner liner inter-facing up to the stool flange. A flanged pipe (15') projects into the tank. The tank is lined with a porous layer (13) and an inner plastic layer (14). The layers extend (18') over the pipe end and along its bore. The inner layer flattens out (19') with a clamp sealing between the tank pipe and connecting pipe flanges.

Title: Cleaning of filler head without dismantling - has fluid check valve mechanically opened by introducing collector tank under filler head
Inventor: GRAFFIN ANDRE JEAN JACQUES
IPC: B67C3/00
Filed: 1976-04-05

Title: Patterned pile fabrics prodn. - by lifting rear needle bed prior to pivoting laying bails over front needle bed to stop pins acting on needles
Inventor: SCHMIDT WALTER
IPC: D04B21/06
Filed: 1976-04-27
Abstract: Patterned pile fabric is produced on a Raschel machine having two needle beds (or a needle bed and a displacement pin bed) and at least one pile yarn inserted bail controlled by the pins. The selected pins are lowered between the needles prior to displacement of the bails over the front needle bed (or the pin bed) to prevent the displacement of the associated needles. The lateral displacement of the bails is prevented until the bails have been swung through the rear needle bed for transposition whereupon the displacement of the bails is effected in the opposite direction during a period which is terminated when the front needle bed has been lifted. Inserting bails can be controlled without lateral displacement of the pins so that all pine and bails can carry out a pivotal movement away from the beds. Pile fabrics with two identical sides can be produced. In the case patternless yarn selection the yarns can be interlocked without significant waste.
Patent DE-2619979-A1 (DE)
Title: Swimming pool algae detector - has floating rubber attachment receiving first deposit of forming algae
Inventor: TYBUSSEK PETER ING GRAD
IPC: G01N33/18
Filed: 1976-05-06
Abstract: The algae detector is used to detect the formation of algae in swimming pool water. It is essential to keep the water of swimming-pools free of algae which cause clouding of the water and make the walls of the swimming-pool slippery. A piece of neoprene (RTM) rubber of square section is glued to a floating sphere. A PVC rod is pushed throughthis piece of rubber and has a bore at the bottom end. The detector is fastened to any point of the swimming-pool by a cord at this bore. As the algae begins to form in the water they are first deposited on the special rubber before clouding is noticeable.

Title: Continuous microwave dielectric heater esp. for extruded material - has peripheral wall slits with short-circuiting collars
Inventor: STENZEL OTTO WALTER
IPC: H05B6/78
Filed: 1976-05-10
Abstract: The appts. comprises a microwave hollow conductor channel through which strand-like (continuous) material is conducted for continuous dielectric heating. The hollow channel has a slit around it near each end; these slits are each surrounded by an electrically conducting collar, the depth of which is one quarter of the wavelength. Pref. the depth of the collars is radial, i.e. perpendicular to the axis of the channel. In another variant, the depth is parallel to the axis, in order to limit the radial dimension. Used in particular to dampen the microwaves to satisfy legal and similar requirements. The arrangement enables heavy, conducting plates, followed by water-colled absorbers to be dispensed with.

Patent DE-2641677-A1 (DE)
Title: Motor control circuit e.g. for power station - uses large scale printed circuit board for up to three KW at five hundred V allowing rapid replacement
Inventor: DIRKSEN HERMANN
IPC: H02K11/33
Filed: 1976-09-16
Abstract: The application is to motor controls produced in large numbers for identical applications, for example soot blowers in thermal power stations. The separate wiring of controls, for example overcurrent relays, timers, lockout devices, pole changing relays and the like is eliminated by making a printed circuit plate with all necessary power and light current connections. The components are then mounted directly onto the plate without wire connections and the whole connected into the motor supply. Wiring errors are eliminated. In the event of failure the whole board can be quickly replaced thus the motor down time is reduced.

Title: Reaction plastic foam prodn. fitting - seals mixing chamber by O=ring and seal ring revolving with rotor shaft
Inventor: TEICHMANN MANFRED
IPC: F16J15/38
Filed: 1976-12-02
Abstract: A device to produce foam parisons from reacting plastics, i.e. isocyanates and polyols, includes a mixing chamber with a mixing rotor, two feed channels and an outlet nozzle. The rotor shaft is sealed by a sliding ring seal. This consists of a sealing ring which is coupled by dogs to the rotor shaft, and of an O-ring which seals both against the shaft periphery and against a bore of the sealing ring extension. The sliding ring provides an effective radial seal and the O-ring an effective axial seal. The rotor shaft suffers no wear because the ring seal revolves with it. The O-ring is also a good thermal insulator to prevent a rotor shaft temp rise from the hot ring seal.

Title: Contactless seal between fixed and moving component - has body with protruding portion towards and enclosing rotary component to keep tilt axis central
Inventor: STEIGER ANTON
IPC: F16J15/34
Filed: 1976-12-09
Abstract: The contactless seal is for use between a component rotating in a chamber to be sealed off and a stationary portion in which a sealing body is mounted. It is movable in the axial direction and has two sealing faces concentric to the rotary component. A number of chambers, open towards the latter, are spaced round the inner periphery of the body between the sealing surfaces. Each is connected via a throttle with the medium under pressure in the chamber to be sealed. The medium exerts an axial thrust towards a sealing surface on the rotary component by acting against a face on the body away from the sealing faces. The body is attached by a bellows-type seal to the stationary portion and is flanged, having its inner peripheral surface also subject to pressure from the medium.

Title: Electronic ignition control system for IC engine - contains modules producing signal proportional to crankshaft displacement and integrating voltage
Inventor: HOSAKA AKIO
IPC: F02P7/067
Filed: 1976-12-10
Abstract: An electronic control circuit which is used to control the ignition timing of an I.C. engine. The ignition period is proportional to a leading control voltage. The circuit is independent of noise pick-up and there is no time delay in the operation. It consists of a module (10) which produces a signal which is a function of the angular displacement of the crankshaft. There is a second module (16) which integrates a leading control voltage depending on the first signal. It then integrates a subsequent constant voltage with a polarity opposite to that of the leading control voltage. This is a function of a second signal, producing an output which is compared in a third module (18) with a reference voltage. The output will represent a technician timing signal when it reaches a given level.

The switching system switches the blower off at a given point of time at which a specified temp. is reached. The blower remains switched off over a period in which the material is held in the furnace. The furnace temp. is regulated during holding time to a specified value, by a relay connected in parallel in the blower motor. The relay can be switched manually only by switch in series with the relay.
Patent DE-2707671-A1 (DE)
Inventor: KAUFMANN MEINOLPH
IPC: G04G9/00
Filed: 1977-02-23
Abstract: An electronic clock with a guest-host liquid-crystal display is described. The specified drive electronics subject the guest-host liquid-crystal display to frequencies in excess of 32 Hz, preferably about 1 Hz. As a result, the power consumption of the guest-host liquid-crystal display is reduced to such an extent that there is no need for the previously used complex twisted nematic cell. Apart from the price advantage, the elimination of the previously necessary polarisers allows the proposed guest-host liquid-crystal cell to have a greater viewing angle for the display. <IMAGE>
