Abstract: ABSTRACT     A child's motor powered vehicle utilizes a unidirectional electric motor supported on a drive shaft which carries at its ends drive members which are engageable with either one of a pair of radially spaced drive surfaces on the drive wheels.          Control levers support the drive shaft adjacent its ends and are pivotally supported on the vehicle so that they may effect movement of the drive shaft end portions and the drive elements from one drive surface to another to effect a reversal in the direction of rotation of the drive wheels.          The drive surfaces are conveniently provided by axial walls of a concentric channel on the inner face of the drive wheels.

Abstract: BOMB-TYPE CONDUCTION CALORIMETER               Abstract of the Disclosure A bomb-type conduction calorimeter consists of a bomb separated from a substantially infinite heat sink by several heat flow detecting elements.  The bomb is enclosed by an inner copper box having a cylindrical interior and a polygonal exterior.  The inner copper box is enclosed by an outer copper box having a polygonal interior.  The heat flow detecting means may be several thermopiles in contact with the inner and outer polygonal surfaces.  The infinite heat sink may be a constant  temperature water bath.  Heat flow directly from the test substance is measured, as opposed to the heat  flow dissipated to  the environment of  the bomb.          The  calorific  values  determined  are  independent  of  the amount of water in the water bath.

Abstract: ABSTRACT OF THE DISCLOSURE         A high-velocity carburetor for an Otto engine compris-ing a slide for changing the cross-section of the suction pipe, a nozzle connection receiving nozzles and a profiled nozzle needle seated on the slide and controlling the cross-section of the noz-zle.  One object is the precise adjustment of the air admixture and thus an optimum mixture regulation as a function of the most important parameters for the operational conditions.  The nozzle connection contains two nozzles, situated coaxially to one another and separated from one another by an intermediate cham-ber.  The intermediate chamber is connected to an outlet channel of a flow control valve having a ferromagnetic membrane-like valve plate.  The valve plate is operable by two coils opposing each other and being connected to push-pull outputs of a pulse generator with adjustable pulse duty factor.  An input channel of the flow control valve is connected with the atmospheric air via an air filter.  For the control of the pulse duty factor an address member is provided which can be addressed by load values, speed values, and temperature values and which contains in the form of a performance characteristic field information values for the pulse duty factor so that the pulse duty factor and thus the air admixture in the intermediate chamber can be adjusted in accordance with said information values.

Abstract: ABSTRACT        A METHOD AND APPARATUS FOR FILLING A           CONTAINER WITH A LIQUEFIABLE GAS      A pump (18) draws liquefied carbon-dioxide from a reservoir (4 or 6) and delivers it via a controllable heater (20) and a filling valve (14) to a cylinder (26) to be filled to any required density.  This receiver cylinder (26) is controllably warmed by a heater (32) while sensors (22,24) are provided to indicate the pressure and temperature of its contents.    For each required density a table of figures is provided relating pressures (above saturation pressure) to temperature, for that density.    A temperature (which must be clear above the lowest temperature at which the receiver will be liquid-full at the required density but which need not exceed the critical temperature) is selected, and the heaters (20 and 32) are controlled so that the receiver cylinder and its contents will converge at or near that temperature as filling is completed.    During the final phase of filling the indicated temperature will rise slowly and the pressure (from the time the receiver is liquid-full) will rise relatively fast.    At the time temperature and pressure match a pair of figures on the table provided, the filling valve (14) is closed cutting off the supply of gas at the fill density required.

The doping concentration and thickness of the epitaxial surface layer (18) are selected in accordance with the REduced SURface Field (RESURF) technique.  A highly-doped buried layer (14) of the first conductivity type may be provided in the sub-strate (11) where it meets the lightly-doped epitaxial buried layer (16).  A highly-doped buried region (19) of the second conductivity type may be located beneath the base region (20) of the device and sandwiched between the epita-xial buried layer (16) and the epitaxial surface layer (18). The advantages of such a device include a substantially reduced "on" resistance, a more compact and flexible con-figuration, improved switching characteristics, reduced base device current requirements, and improved isolation. The device may be further improved by providing a buried annular region (21) of the first conductivity type around and in contact with said buried region (19), and a surface adjoining annular region (23) of the first conductivity may be provided adjacent the base region (20.

Abstract: ABSTRACT         Disclosed is a quick-release locking buckle assembly for safety harnesses, including a housing, and a main trunnion mounted in the housing which is actuable by a release member.  An anchor plate interacts with retaining bolts for retaining belt connection pieces, the anchor plate being biased into a locking position.  The trunnion has a reduced portion extending through an orifice in the anchor plate and is guided centrally with respect to the anchor plate.  The trunnion has a retention part engageable under the anchor plate and also with a device for the automatic separation of the belt connection pieces from the retaining bolts by means of pressure, independently of the actuation of the release member.  A channel extends from the automatic-separation device up to a pressure member acting on the anchor plate counter to the bias being applied to it.  The channel is interrupted, in the locking position of the assembly, by a guide pin securing the main trunnion of the assembly.

Abstract: ABSTRACT A continuous process for removal of ammoniacal nitrogen from water is disclosed.  This process is useful for maintaining water quality in aquaculture operations, e.g., fish hatcheries and the like.  A particulate stream of zeolitic ion exchange material is circulated continuously through an exchanger and a regenerator.  An aqueous process stream containing ammoniacal nitrogen, e.g., ammonia, is passed through the exchanger in continuous counter current liquid-solid contact with a stream of particulate, ammoniacal nitrogen-sorbing zeolitic ion exchange material of natural or synthetic origin.  A treated liquid water stream having a reduced ammoniacal nitrogen content exits from the exchanger, as does a stream of ammoniacal nitrogen-enriched particulate zeolitic ion exchange material.  The latter stream is regenerated in the regenerator at a temperature of about 350°C. to about 650°C. while an oxygen-containing gas stream, e.g., air, is passed in continuous counter current gas-solid contact therewith.  Gases emanating from the regenerator are used to preheat the ammoniacal-nitrogen enriched particulate material that enters the regenerator. The regenerated stream of particulate, ammoniacal nitrogen-sorbing zeolitic ion exchange material is recycled to the exchanger.
