Abstract: ABSTRACT OF THE DISCLOSURE      A temperature sensor includes a pair of transistors each connected in series with a respective one of a pair of resistors across a source of voltage.  The emitters of the transistors are connected together and the collectors are con-nected to a respective input of a differential amplifier.  An output of the amplifier drives a voltage divider circuit having a pair of outputs each connected to the base of a respective one of the transistors.  The transistors are operated at different current densities and the ratio of such current densities is maintained constant with changes in temperature by feedback from the amplifier which has an output which is porportional to absolute temperature.  In a second embodiment the supply voltage is generated by a current source, such that it will vary with changes in the load thereon.  An output of the amplifier is connected to the base of a transis-tor which is connected across the voltage supply lines and the voltage divider, such that the voltage across the divider varies in accordance with the output of the amplifier.  In a third embodiment the two sensing transistors each have a second emitter.  The emitter areas of one of the transistors are unequal, such that a potentiometer connected from the first emitters of the transistors to the second emitters of the transistors permits calibration of the ratio of the current density of one transistor to the current density of the other transistor.

Abstract: VERTICAL DEFLECTION CIRCUIT                Abstract of the Disclosure First and second controllable switching stages are respectively coupled between a source of horizontal retrace pulses and a capacitor connected across a vertical deflection winding.  A modulator is coupled to the switching stages for controlling the timing of conduction thereof relative to the timing of the horizontal retrace pulses.  One switching stage charges the capacitor in one polarity with pulses of current of gradually decreasing amplitude and duration during a first portion of the vertical trace interval and the other switching stage charges the capacitor in the opposite polarity with pulses of current of gradually increasing amplitude and duration during a second portion of the vertical trace interval.  The capacitor supplies scanning current of first and second polarities to the vertical deflection winding during respective first and second portions of each vertical trace interval.  The energy for producing the vertical sawtooth scanning current is thus derived from horizontal (line) scanning pulses which are coupled to the vertical deflection winding.

Abstract: PREPARATION OF BROMINE            Abstract of the Disclosure Bromine is produced by reacting chlorine and ethylene dibromide in the presence of an aluminum halide catalyst, e.g. aluminum chloride.  A small amount of bromine present prior to chlorine addition shortens the induction period.  Some decomposition of the organic product occurs if it is distilled in the presence of aluminum-containing residues.  These residues can be removed by water wash which can be followed by drying with H2S04.  After such treatment, ethylene dichloride can be recovered by distillation without substantial decomposition.  Bromine is difficult to ship and store.  Because of its corrosive nature, it requires special vessels and precautions.  This invention relates to recovery of bromine from ethylene dibromide, a compound that is readily shipped and stored. Hence, this invention affords means which make the storage or shipment of bromine, especially in larger quantities and for appreciable distances, more readily carried out.

Abstract: ABSTRACT OF THE DISCLOSURE           A semi-trailer is connected to an agricultural-type tractor by means of a coupling dolly.  The coupling dolly has a chassis which is supported by wheels at tis rear end and is connected to a weight transfer hitch at its front end.  The semi-trailer is connected to the dolly by means of a universal coupling supported between the ends of the dolly chassis and having mutually intersecting rearwardly disposed pitching, rolling and yawing axes.  The weight transfer hitch is pivotally connected to the tractor for articulation about a horizontal pitching axis extending transversely of the tractor, between the axes of the front and rear wheels of the tractor and below the level of the axis of the rear wheels of the tractor.  The weight transfer hitch also has bearing means, disposed to the rear of the horizontal forwardly disposed pitching axis, for accommodating rolling and yawing articulation between the dolly and the tractor, the bearing means provided for yawing articulation being disposed on an axis which passes through the bearing means provided for rolling articulation.  The coupling dolly is therefore capable of relieving the rear axle of the tractor of part of the loading of the semi-trailer while providing rolling stability for the semi-trailer and enables the connection between the semi-trailer and the tractor to be effected by means of a smaller weight transfer hitch than would otherwise be possible.

Abstract: Abstract A system including a non-tracking reflector-collector for the concentration and collection of solar energy.  An energy-collecting plate is disposed upright along a substantially horizontal axis substantially coincident with the east-west direction of the earth.  The collector plate is positioned within a semi-tubular reflector having parabolic sidewalls.  The reflector surfaces on opposite sides of the collector plate are parabolic surfaces, each having a focal point approximately coincident with the upper terminal edge of the collector plate. The axes of the parabolas which define the respective surfaces are rotated about or diverge from their common focal point at a substantial angle.  The reflector sides are of laminated con-struction having a base portion of a lightweight rigid plastic sheet, an underlayer of plastic corrugated board and a reflective film on the interior surface.  The collector plate receives energy entering the aperture between the reflective surfaces. In one of the preferred embodiments, the plate elevates the temperature of a heat exchange medium flowing therethrough.  The heat exchange medium provides for storage and use of the collected energy.  In a second embodiment, the collector plate receives solar energy which is converted into electrical energy for storage and use.

Abstract: IN THE UNITED STATES PATENT   AND TRADEMARK OFFICE                      Application of Relating to MEMORY ARRANGEMENT FOR USE IN A DIGITAL DATA PROCESSING SYSTEM         Abstract of the Disclosure A memory arrangement for a digital data processing system that includes a high-speed associative memory unit and a random access backup memory unit,  Each time a central processor initiates an operation to transfer the contents of a location to itself, it issues an address.  If the associative memory unit which contains the data from some of the locations in the backup memory unit, contains corresponding data, it per-forms a reading memory cycle and transfers the data directly to the central processor.  If the data is not available, or if the central processor is transferring data to the addressed location, the associative memory unit causes the backup memory unit to perform a corresponding memory cycle thereby to update the corresponding locations in both the associative and the back-up memory units.  Other memory units and input/output units also communicate with the backup memory and the associative memory units.  For example, a secondary storage device may trans-fer data to locations in the backup memory unit.  If the associative memory unit contains a corresponding location, the contents in that location are modified to indicate that the data in that location has been changed.
