Title: Noise rejecting power network short circuit detector - uses current pulse to activate Schmitt trigger and two monostable multivibrators
Inventor: MEISSL ROBERT
IPC: G01R31/02
Filed: 1975-03-25
Abstract: A relatively noise insensitive power network short circuit detector and alarm circuit, which operates on a current surge principle but which rejects short lived surges produced by motors starting etc. The current charge is detected magnetically, and the ensuing pulse used to trigger a Schmitt trigger circuit, a monostable multivibrator of some 3 seconds pulse duration and, at the end of this time, another multivibrator producing typically a pulse of 100 ms.

Title: Control circuit for brake system - with two switches to monitor effectiveness of dual brake circuit
Inventor: BOCK WILLY
IPC: B60T17/22
Filed: 1975-04-08

Title: Thermoplast panels moulded in successive treatment stages - using spiked frame to carry panels through all stages
Inventor: DOERRSCHUCK HEINRICH
IPC: B29C51/26
Filed: 1975-04-25
Abstract: A method of moulding plastics panels or plates of a thermally deformable plastics utilises gas pressure and or vacuum and a succession of treatment devices in a continuous row. Each individual panel or plate is taken from a stack, and placed upon a needle frame in which it rests upon vertical needles, this frame and the panel are moved to the next stage where heat is applied, accompanied by downward pressure, causing the neddles to penetrate into the panel, the needle frame surrounded by a supporting frame is now moved forward again by a conveyor to the next stage and any further stages required, then finally tilted through a right-angle out of the plane of the conveyor and removed. The arrangement is more systematic and rapid in operation than a typical pressing frame system, in which all the operations take place in a single location. It is however not as bulky as a turntable system. It utilises the advantage of conventional sheet-treatment machines, in that needles for transversely stretching and supporting the plate are used, in the present case penetrating into the plate by thermal action.

Abstract: Connecting of the corners of mitre-cut soft metal hollow sections when, in the open ends of the hollow section rods, a connecting corner angle is inserted and part of the section wall is pressed into the recesses formed in the corner angle by a pair of press tools arranged symmetrically to the section corner to be connected. The ends of the section rods (1) are guided internally and externally by stops (3, 4) symmetrically to the mitring plane. The press tools (6, 6c), at an angle of 150 deg. to 180 deg. are moved synchronously and with increasing force to the recesses (8). They impinge with their effective edges by such an amount (a) in front of the recesses (8) of the corner angle (2) on the wall of the hollow section, that the ends of the profile rods are pressed together on the mitring face. The wall material is pressed against the corner angle (2) then squeezed, stretched and thinned, expanded in structure and fixed. The tools then press the material into the recesses (8) of the corner angle.

Abstract: Highly conc. powdery dispersion- and vat dye compsns. contain, by wt., (a) 50-80 (60-70)% of >=1 finely dispersed dispersion- or vat dyes, and (b) 20-50 (30-40)% condensn. prod. as dispersant. Dispersant is prepd. by re-condensn. of (i) a condensate (I), which is prepd. by condensing phenolsulphonic acids, free from condensed ring systems, with urea and HCHO or HCHO-yielding matls., in mol. ratio 1:1-1.5:1.7-2.2, with (ii) a condensate (II) prepd. from phenol and HCHO, in mol. ratio 1:1, in a strongly alkaline medium. Re-condensn. takes place in a strongly acid medium. Before re-condensn. with (I), (II) is left to react 1-2 hrs. at pH 2-4. Compsns. dye textiles in pure colour shades, including bright yellow to orange. Condensate does not colour or soil textile fibres. Bright effects are obtd. when using optical brighteners. Even sensitive dyes can be dispersed at higher temps., e.g. 60-90 degrees C, to form stable dispersions. Dispersions can take place at pH 4-7 without increasing viscosity. Dispersion velocity achieved is higher than with standard dispersants. In an example, dispersant prepn. (I) was pred. from 94 pts. sulphonated phenol, 60 pts. urea and 190 pts. 30% HCHO. (II) was prepd. from 47 pts. phenol and 50 pts. 30% HCHO.

Title: Alkaline beverage container washing wastes - neutralised by immission of carbon dioxide in liquid phasre at automatically controlled rate
Inventor: PRUCHA JAROSLAV DIPL ING
IPC: C02F1/66
Filed: 1975-10-03
Abstract: Alkaline wastes from container (bottle) washing machines in the beverage industry are neutralised by the immission of Co2. Liq. CO2 is raised to the temp. of the wastes and injected in the liq. phase directly into the wasted to be neutralised. This saves the electric heating which is needed to prevent icing up of the expansion values if liq. CO2 is allowed to expand to gas.
