Abstract: TITLE OF THE INVENTION               CONVEYOR WITH SORTING ACCESSORY     ABSTRACT OF THE DISCLOSURE    Elongated components such as piston pins may be sequen-tially fed at an entrace point onto a conveyor connected to a distant discharge point.  The conveyor includes a pair of guides so spaced to allow the pins to fit loosely there-between and a stop plate which limits downward movement of the pins.  An elongated drive plate having a top edge positioned between the guides and below the pins is rotated in an elliptical-like pattern so that the top edge lifts the pins from the stop plate, moves the pins forward and then re-engages the pins with the stop plate at a point forward of the point of initial lifting.  The pins thus may be conveniently stepped between the entrance point and the discharge point as well as accumulated and stored if such is required.  The conveyor may include sorting means to separate the pins into different groups having equal diameters where pins of varying diameters have been inadvertently mixed.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE    A metallic electrical contact element is disclosed having a discrete convex curvilinear surface portion intended for electrical contact having a localized conductive electrodeposited contact point thereon.  The contact point is produced by providing a roller carrying electrolyte on its periphery for plating said contact point, positioning the metal contact element transversely to the axis of the roller with the periphery of the roller in tangential engagement with the contact point, rotating the roller while passing on electric current between the contact point and the roller surface whereby a conductive electrical contact point is produced on the convex curvilinear surface.  The thickness of the electrodeposited contact point smoothly decreases outwardly from the center thereof.  Such a metallic contact element reduces the amount of material used in plating the electrical contact point.

Abstract: FAILURE PROTECTION CIRCUIT FOR A TWO-MOTOR LIFT TRUCK An electrically operated dual motor drive system having first and second reversible traction motors driven by a power source. Motor control circuitry for controlling the direction of current flow through the motors is designed to be actuated by only two coils. Preferably, control circuits employ an arrangement of normally open and normally closed contacts such that the two motors operate in reverse directions in the event of a complete system malfunction. A line contactor is advantageously utilized to simultaneously serve as a main power disconnect for a variety of motors within the system.

Abstract: PHN.9821                10 ABSTRACT:            A television camera tube comprising in an evacuated envelope an electron gun to generate an elec-tron beam which during operation of the tube is focused to form a spot on a photosensitive target, on which tar-get a potential distribution is formed by projecting an optical image on it, which target, by scanning with an electron beam, provides signal corresponding to the said optical image, which scanning takes place in a line deflection direction and a frame deflection direction. When according to the invention the spot has an elongate shape, which shape is determined by a line at the edge of the spot which interconnects points having the same current density and of which 1.4 ? k ? 2 where k is the ratio between the lengths of the long and short axis of the spot and the long axis of the spot divides the acute angle between the line deflection direction and frame deflection direction in such manner that 0°? .beta. ? 60° where .beta. is the angle between the long axis and the frame deflection direction, a television camera tube is obtained the modulation depth of which is larger than in comparable tubes having a circular spot and the modulation depth of which is moreover less and substantially symmetrically dependent on the orientation of the usual  test pattern for the modulation depth.

Abstract: ABSTRACT A process for degassing polymers and copolymers which are prepared by bulk polymerisation of a vinyl chloride-base monomer composition.  The polymer-isate being kept in an agitated condition, the monomer composition to be removed is adjusted from the polymerisation pressure to an absolute pressure of less than 0.16 bar, the polymerisate is brought to or maintained at a temperature which is at least equal to 70°C and lower than the temperature at which degrad-ation of the polymer or copolymer begins, and said pressure and temperature conditions are maintained substantially until degassing stops.  After the pro-portion of residual vinyl chloride monomer in the polymer or copolymer has been reduced to a value below 2000 mg/kg, the polymerisate is brought into contact with water to which at least one anionic surface active agent is added.  The resulting polymers and copolymers have a considerably enhanced sieving capability.

Abstract: ABSTRACT OF THE DISCLOSURE         An amorphous silicon PIN semi-conductor device is manufactured by (i) providing a substrate (10) with a layer (11) of an electroconductive material, for example molybdnum, which forms an ohmic contact with N+ amorphous silicon; (ii) sequentially sputtering a layer of N+ doped amorphous silicon (12), a layer of intrinsic, I, amorphous silicon (14) and a layer of P+ doped amorphous silicon (16).  A layer (18) of an electroconductive material, for example semi-transparent indium tin oxide, is sputtered onto layer (16) to form an ohmic contact there-with.  A grid current-collection electrode (20) is optimally patterned on layer (18).  The sputtering step parameters are controlled, and the steps can be per-formed in a single vacuum system and vacuum pump-down procedure.  The semi-transparent layer (18) can thus be depointed on a thin P+ doped layer (16) without deteriora-tion of the junction forming characteristics of the underlying amorphous silicon layers.

Abstract: IGNITION TIMING CONTROL                         ABSTRACT         A programmed timing control controls the occurrence of timing signals relative to engine position in systematic relation to engine speed to provide such spark at a time appropriate for a first fuel at each engine speed.  An alternative fuel timing control produces a controlled timing interval systematically related to engine speed and changes the timing of such spark by the controlled timing interval to provide such spark at a time appropriate for a second fuel at each respective engine speed.  A variable dwell control provides a dwell control signal for controlling the application of current to the ignition coil.  A signal generator coupled to the timing means generates a time varying signal rising in magnitude substantially monotonically and preferrably linearly with time following each interruption of such current until a later time corresponding to the next succeeding interruption of such current.  A reference signal generator responds to the magnitude of the time varying signal at each interruption of the current to produce a dwell reference signal of magnitude a predetermined differential less than the magnitude of said time varying signal at such interruption.  The differential is preferably constant at moderate engine speeds and varies inversely with speed at high and low speeds.  A comparator compares the time varying signal with the dwell reference signal and produces the dwell control signal when the time varying signal substantially reaches the magnitude of the dwell reference signal.          The dwell control signal is advanced upon misfire.

Abstract: B.  ABSTRACT OF THE DISCLOSURE:    Fresh produce is loaded into an enclosed trailer, and the doors closed.  Chilled water is pumped through overhead sprinkler pipes to chill the product to about 35 degrees Fahrenheit.  The excess water is drained through a special drain at the bottom of the trailer.  Liquid nitrogen is used to maintain the trailer cold during transit and storage.          Nitrogen tanks within the trailer are filled during the water chill operation.  The nitrogen tanks are bled during the filling operation and the bled nitrogen extends through expansion tubes which are located co-axially within the water sprinkler tubes in the ceiling.  From there the nitrogen is fed through exhaust pipes along the floor of the transport to purge the product of atmosphere and more particularly to purge it of respiration gases.  During transport, the liquid nitrogen is fed into the overhead expansion tubes for refrigeration and again the evaporated nitrogen is fed to the exhaust pipes along the floor to purge the product of respiration gases.  The floorboards are designed and built to have the strength to haul a general cargo so that the trailer may be put to the most efficient usage available on back haul.
