Abstract: INK JET LINE PRINTER                ABSTRACT OF THE DISCLOSURE      In an ink jet serial printer, a drop collector has horizontal and vertical collector sections or gutters.  Unused drops are diverted in the direction of motion during uniform velocity of the ink jet head into the vertical section and into the horizontal section during acceleration/deceleration portions of head motion.  A bias potential applied to the vertical drop deflector is removed during acceleration/deceleration to cause unused drops to be directed to the horizontal collector section.

Abstract: Abstract of the Disclosure A new sequence of steps provides more control in the formation in sheet metal of weakening lines of the type characterized by an integral yet fractured section. Basically, the method employs, in making so-called easy-open can ends, for example: 1)  peripherally forming a closure in the sheet metal; 2)    coining or scoring a profile surface of the closure, not to the depth required for fracture, but to establish residuum thickness along the desired line; 3)    next, overforming the closure at least in part to integrally fracture the residuum along that coined line; and 4)    lastly, swaging to seal or tighten edges of the fractured section.

Abstract: Abstract A known pipe branch fitting has a member engaging the pipe, and a fitting part which can be moved inward to compress a gasket against the pipe and has an inner end portion locating in a hole in the pipe.  In this invention, the gasket in uncompressed condition has a lower surface curved to conform with the pipe, and a flat upper surface.  The fitting part is screw-threaded into the embracement member and can be tightened up using a wrench or other tool.  The movement of the upper end of the fitting part indicates whether the inner end portion is properly located in the hole in the pipe or whether it is ledging on the pipe wall.

Abstract: ABSTRACT OF THE DISCLOSURE         A sweep auger is driven by an orbital motor  deriving power from an hydraulic pump mounted on the main auger tube and driven by the main auger source of power.  The sweep auger and orbital motor are pivotally mounted above the auger intake to feed grain to the intake instead of to the end of the main auger tube as is conventional.  A release valve can be set to unload the sweep auger jams and the sweep auger can be controlled by the operator either by a control on the orbital motor or a control connecting the hydraulic pump to the main source of power.  A small hopper is provided to enable all of the grain in the bin to be elevated and the outer end of the sweep auger is of a slightly larger diameter to ensure adequate feeding of the inner or discharge end.

Abstract: Abstract of the Disclosure There is provided a seed dressing composition comprising plant utilisable chromium (e.g. chromium trioxide) and plant utilisable indium (e.g. indium hydroxide), for treatment of corn seeds prior to planting.  Treatment of the seeds with such a dressing material affects their receptivity to zinc, so that such treated seeds may be grown in a zinc rich soil and, in the case of certain corn varieties, give enhanced yields or shorter maturation times.  The zinc may also be incorporated in the seed dressing composition according to the invention.          Alternatively or in addition, it may be applied as fertilizer to the soil prior to planting the seeds therein.

Abstract: Abstract of the Disclosure A centrifugal pump includes an impeller and a volute casing.          The impeller comprises a main disc and a plurality of vanes which project axially from at least one side of the disc. A fluid passage is formed between each pair of adjacent vanes. The passage has a constant depth and a gradually decreasing width from an inlet to an outlet thereof. Each fluid passage assures a flow of the fluid along the front surface of the associated vane and prevents the occurrence of a vortical flow therein. The volute casing has an inner surface which is substantially U-shaped in section and effectively converts the kinetic energy imparted to the fluid by the impeller into hydraulic pressures.

Abstract: ABSTRACT OF THE DISCLOSURE          A dry method and apparatus for treating an effluent gas stream in order to facilitate the removal therefrom by conventional means of contaminating particulates, particularly those in the submicron range.  Target particulates which are larger than the submicron contaminating particulates are dispersed in a secondary gas stream.  The secondary gas stream is then introduced into the effluent gas stream.  The manner of introduction is such that the contaminating particulates impact with and are captured on the larger target particulates.          The target particulates and the contaminating particulates inertially impaced thereon are then separated from the combined effluent and secondary gas streams by conventional gas cleaning equipment.

Dirksing ABSTRACT OF THE DISCLOSURE       A passive dosing dispenser for issuing, for example, a predetermined volume of a toilet tank additive solution into a toilet tank as the water is draining there-from while the toilet is flushing.  A preferred dispenser comprises a product chamber for containing a quantity of a solid type product which can be dissolved in water to form a toilet tank additive product solution, a reservoir for containing a quantity of said solution in fluid communication with said product chamber, an inlet/discharge conduit having its lowermost end in fluid communication with said reservoir and its uppermost end in fluid communication with a syphon tube, an air trap disposed adjacent said inlet/discharge conduit for isolating said product solution from the toilet tank water in said syphon tube during quiescent periods, and an air vent in fluid communication with said reservoir and product chamber.  In operation, while the water in the toilet tank is receding from about the dispenser, a predetermined quantity of said product solution is syphoned from said reservoir through the inlet/discharge conduit and is dispensed through the syphon tube.  In a particularly preferred embodiment, the dispenser provides a pair of air-locks when completely immersed in a full toilet tank which air-locks isolate the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods.

Abstract: Abstract:   A nonalloyed ohmic contact to an n-type Group III(a)-V(a) compound semiconductor body is formed by epitaxially growing a Group III(a)-V(a) n++-layer doped to at least 1019 cm-3 between the semiconductor body and a metal contact layer.  The metal layer forms an ohmic contact without requiring heating above the eutec-tic temperature.  In order to avoid contamination of the metal-semiconductor interface, a metal contact layer may be deposited in situ after MBE growth of the n++-layer.          This technique results in both a metal-semiconductor interface with smoother morphology and also an ohmic contact without heating above the eutectic temperature.          These procedures are specifically described with refer-ence to the fabrication of GaAs FETs.

Abstract: ABSTRACT     An electronic  control system particularly suited for use with an automatic fuel dispensing system uses a centrally  located computer to supply serial polling signals to various sub-stations. At the sub-stations, the polling signals are decoded into  signals used  to  control the operation of specific system relays operated by the system.  The status of the decoded polling signals  as  well as  the  operating  status  of  the relays is supplied back to the computer for verification.  A  time-out control circuit continuously monitors  the input polling signals applied to the relay terminal. If activity does not appear on  the  input  signal  line  at  the terminal after a pre-established time interval, all of the system relays at the terminal are turned off  or  rendered  inoperative, irrespective  of  the  status of the relay control signal obtained from the output of the  polling  signal  decoding  circuit.  As a consequence,  if  the  remotely  located  computer  should fail to properly operate for  any  reason,  the  system  is  placed  in  a "fail-safe" standby condition of operation.
