Abstract: ABSTRACT               DETONATING GAS GENERATOR           A generator for oxyhydrogen gas comprises a plurality of flat metal electrodes 1-7 mounted parallel with ring-like spacers 10-15 between each pair of adjacent electrodes and bolts 16,17 clamping the spacers and elec-trodes together to provide a sealed cell between each pair of electrodes and within the periphery of the respective spacer.   An inlet 18 for electrolyte is connected to one outer cell and an outlet 19 for the gas is connected to the other outer cell.   The electrodes 3-7 are imperforate except for apertures 20 adjacent the tops of the cells and in use a DC power source 21 is connected across outer electrodes 1,2.   The generator is of simple construction and achieves good cooling, high mechanical strength against internal explosions and ensures a minimal quantity of explosive gas in the upper regions of the cells.

Abstract: MOVABLE SOLAR COLLECTOR                  Abstract of the Disclosure A movable solar collector structured to move between a first or solar collecting position and a second or storage posi-tion as desired by the user.  The movable solar collector may be in the nature of a closure member adapted to close an entryway in the first position and open that entryway in the second position.          One preferred form is an overhead door, e.g., a garage door, com-prised of a plurality of door panels.  Each door panel is struc-tured to collect solar energy, and is hinged to adjacent door panels so that the panels can be moved between a generally verti-cal closure position where the collector is exposed to solar energy, and a generally horizontal open position where the collec-tor is elevated above ground level.  The plural door panels are structured to establish an integrated hollow collector unit when in the first position, the plural panels cooperating with a fluid that circulates interiorly thereof for absorbing solar energy into that fluid.  One of the panels is connected with exterior piping in the collector's first position for transmitting solar energy received by the fluid to a remote use location.

Abstract: ABSTRACT OF THE DISCLOSURE           A foamed polystyrene board useful as a thermal insulating material is produced by melting a polystyrene having a melt index of from 0.5 to 5 under heat in an extruder, mixing the molten mass with a blowing agent composed of methyl chloride and dichlorodifluoromethane, and extruding the resulting foamable molten gel from the extruder.  As a novel essential feature, a flowability improver having a-melting point higher than 70°C; such as an aromatic sulfonamide, a brominated aromatic compound, a brominated alicyclic compound or a poly(.alpha.-methyl styrene), is mixed with the polystyrene within the extruder to impart superior extrusion formability.  The foam has good dimensional stability both at room temperature and higher temperature, high mechanical strength and superior thermal insulation.

Abstract: 4.4.79                    1                   PHN.9301 ABSTRACT     A halogen incandescent lamp having a light-pervious envelope containing a gas filling comprising a rare gas, hydrogen and bromine. The envelope also contains a tungsten filament and an oxygen getter. The oxygen getter consists of an intermetallic compound of at least one first metal from the group consisting of Ta, Ti, Zr, Hf and Nb and at least one second metal from the group consisting of Pd, Pt and Au, but which intermetallic compound is not a tanta-lum-gold or a niobium-gold compound.        These intermetallic compounds are sufficiently stable that although they react with oxygen, they do not react with hydrogen bromide.        Consequently the presence of such an intermetallic compound in such a halogen incandescent lamp does not interfere with the tungsten-bromine cycle, and thus the maximum quantity of the intermetallic compound which is present in such a lamp is not critical.

Abstract: SELECTIVE COMMUTATION CIRCUIT FOR AN INVERTER               ABSTRACT OF THE DISCLOSURE        The commutation circuit of an inverter is actuated only when the main thyristors cannot be transitioned to the noncon-ducting state by the removal of the gate signal.  If a commu-tation pulse is required, the commutation capacitors are charged to the appropriate voltage level immediately prior to the switching point so that they may provide a sufficient pulse of current to extinguish the current through the thyristor.          The commutation capacitors are then returned to a stable voltage level until another commutation pulse is required.

Abstract: AN OPTIMIZED DIGITAL DELTA MODULATION COMPANDER HAVING TRUNCATION EFFECT ERROR RECOVERY                          Abstract A digital delta modulation compander circuit makes advantageous use of the mathematical truncation created during the computation of step sizes to create a non-linear step size variation which differs from the optimum desired step size but causes convergence recovery during error conditions.  It has been dis-covered that the truncation involved in the inaccurate approximation of mathematical calculation of the step sizes produces an advantageous result which leads to an optimized digital delta modulation compander that will recover from transmission errors over a wider range and with greater efficiency than other methods.

Abstract: 1. "A process for reducing the width of a flat metal product by rolling"                  ABSTRACT OF THE DISCLOSURE          To reduce the width of slabs from a reheating furnace to the width required in a finishing rolling train, thereby making it possible to feed slabs of only one width, or only a few widths, into the reheating furnace, the invention proposes rolling the slab in a width-reducing roll train in which the slab is subjected to traction such that plastic deformation occurs between the roll sets.  In particular the width-reducing roll train has only one set of thickness rolls and has one or more sets of width rolls, thereby minimising the length of the roll train and consequently reducing the lengths at the ends of the slab which are not subjected to the traction.
