Title: Distilled water produced by evaporation - transferring heat released by condensation to dirty water and passing it to evaporator
Inventor: BAUER OTTO
IPC: B01D1/02
Filed: 1975-06-27
Abstract: Distilled water is produced by evapn. of dirty water and by condensn. and collection of the produced steam. The heat energy released during condensn. is transferred to the dirty water. The condensate is passed in counterflow through a dirty water column without heat convection currents to extract the remaining heat. Preheat dirty water from the head of the column is supplied to the evaporator and fresh dirty water is introduced at the bottom. This recovers the energy required for evaporation almost completely so that, apart from the starting phase, little energy is required. An inexpensive construction is possible by combining the dirty water tank with the evaporation chamber.

Title: Colour location of colour sample measuring device - is by brightness method and has three photoelectric receivers with colour filters
Inventor: STURM WALTER
IPC: G01J3/46

Title: HV pulse generator circuit for gas cigarette lighters - works from LV DC source and has oscillating AC-DC converter
Inventor: SCHAEFER HORST
IPC: H03K3/57
Filed: 1975-09-18
Abstract: The pulse generation is designed for spark ignitors, and has a convertor which charges to a certain voltage and an ignition capacitor which then discharges through a voltage augmentation system. A thyristor (5) has a first conduction state when a supply voltage is applied. It allows in this state the convertor to oscillate freely. When capacitor (12) discharges, or a discharge takes place in the spark gap (18), thyristor (5) trips to its other state and stops convertor oscillations. The thyristor variable potential terminal is connected to the remainder of the circuit through two transistors (6, 7).

Title: Frozen gas pellets esp. for nuclear fusion experiments - produced without initial movement to permit accurate projection towards target
Inventor: RIEDMUELLER WOLFGANG DIPL PHYS
IPC: F25J1/00
Filed: 1976-03-17
Abstract: A method of making pallets of gases which solidify at very low temps. is intended for use where the pellets are to be supplied in a controlled manner to a predetermined position. A rod of the solidified gas is produced and particles are then cut in succession from the end of this rod without contact by means of thermal radiation. Pref. the thermal radiation is produced by heated wires. Used for the production and transmission of pellets of materials which solidify at =-80 degrees C. Specifically, the method is used for the prodn. of solidified pellets of gas which are to be propelled into the focal point of laser and electron beams to produce make-up fuel in experimental investigations of controlled nuclear fusion and also in fusion reactors of the future. By cutting off the pellets from the rod without any contact with mechanical parts, sideways displacement of pellets and other disturbing movements are avoided, so that they can be directly accurately to the desired location.

Title: Thermostat with miniature rocker switch - has U:shaped metal housing, open at three sides with switch between side walls
Inventor: SPAHN EMIL
IPC: H01H35/26
Filed: 1976-05-05
Abstract: The miniature rocker switch is insertable into the thermostat housing (6) and has a switching pin (2) with an actuating spring element (14) filled with expansion liquid. The element is connected to a temperature sensor (16) by a capillary (15). The switch is swivelled by a regulating screw in the thermostat housing which is U-shaped and open at three sides. The miniature rocker switch is inserted between the housing side walls with little free play. It has at one end a transverse groove pressed against an axis (7) in the thermostat housing by a spring. The latter also presses the other end of the switch against the regulating screw. Thus at the latter displacement the switch swivels about the axis (7), which results in variation of the distance of the switching pin from the actuating spring element (14).

Title: Screw-operated, plasticising unit for polymer processing - uses reduced pressure for conveying holding cpd. from reservoir to screw
Inventor: BOROVIKOVA GEB PISKUNOVA SOFIA
IPC: B29C48/50
Filed: 1976-10-07
Abstract: Plasticising unit in polymer processing machine has a polymer supply reservoir and a conveying screw enclosed in a heated barrel. In the zone where the moulding cpd. is charged, from the reservoir, to the screw, a means is arranged adapted to generate reduced pressure within the barrel. This facilitates shifting the moulding cpd. from the reservoir into the screw channel. Esp. used for processing of (particulate) moulding cpds. having a relatively low apparent density so that they are less amenable to gravity-fed conveying from reservoir to screw. Any tendency to clog the inlet tothe barrel is minimised. The reduced pressure in the barrel also promotes removal of volatiles from the cpd.

Title: Automatic ghost image suppressor for TV receiver - mixed undelayed video signal with video signal delayed by ghost delay
Inventor: NAKAGAWA ISAO
IPC: H04N5/21
Filed: 1976-10-22
Abstract: The automatic ghost-image suppressor, for a TV receiver, has a delay line, to delay the video signal by an amount of time equal to the ghost image's delay, and a gain control to set the amplitude of the delayed video signal. A mixer mixes the undelayed video signal with the amplitude-set video signal and thereby produces a video signal with suppressed ghost image. A gate samples the residual ghost image from the output of the mixer durng the vertical blanking interval in sync. with the separated sync. signal. A detector detects the residual ghost in the vertical blanking interval and controls the gain of the gain control accordingly.
