Abstract: ABSTRACT A liquid drop (i.e. ink jet) printing system is disclosed of the type wherein many parallel drop streams are continuously generated. Selected drops from each stream are deflected laterally to address the multiple pixels of a segment of a raster image scan line. The scan line segments addressed by each stream collectively compose a full scan line of a raster image. The drops are deflected by electrostatic fields tilted relative to the scan line to compensate for drop placement errors due to the relative motion between a target and the drop generator. The tilted fields are created in the spaces between interleaved teeth of two electrode members resembling garden rakes. The teeth are triangular, in cross-section at least partially, to tilt the fields. In addition, a drop collection gutter is positioned adjacent each tooth of one of the rake members. The gutter collects drops from adjacent streams not intended for marking a target. The drops within adjacent streams are swept in opposite directions. The alternately tilted (clockwise and counterclockwise) deflection fields and the appropriate sweep direction are selected for a given target direction of travel. The rake members move apart during start up and shut down of the drop streams.

Abstract: ABSTRACT OF THE DISCLOSURE:     A plasma melting furnace includes a water-cooled bottom electrode of copper and a temperature probe connected with the bottom electrode. A wearing part of steel is provided in the bottom of the furnace, covering the bottom elec-trode. At least one counter electrode is arranged at a dis-tance above the wearing part for the formation of the plas-ma jet. In order to prevent the risk of a melting through of the bottom electrode as far as to its water-cooled sec-tion on account of a secondary arc, a metal layer is pro-vided between the bottom electrode and the wearing part.        The metal layer is formed by a metal having a low thermal conductivity and a low melting point, as compared to copper, as well as a high melting enthalpy. Preferably, a metal layer of lead or its alloys with tin and/or zinc is pro-vided.

Abstract: PROCESS FOR REMOVING HYDROPEROXIDES            AND ALDEHYDES FROM ALLYL-ALKYL ETHER                  ABSTRACT OF THE DISCLOSURE          Described herein is a process for the conversion of hydroperoxides, present in allyl-alkyl ethers to products including .alpha.,.beta.-unsaturated aldehydes and for reducing such .alpha.,.beta.-unsaturated aldehydes to alcohols prior to the use of the ether as a feedstock in a hydroformylation reaction to produce the corresponding ether aldehyde.  The process involves contacting the ether with a metal hydride, either in aqueous solution and/or by means of an ion exchange resin.  Such treat-ment decomposes the hydroperoxides and then reduces their .alpha.,.beta.-unsaturated aldehyde decomposition products, thereby reducing the catalyst inhibition period present in the hydroformylation reaction which is observed when such .alpha.,.beta.-unsaturated aldehyde impurities are present.

Abstract: ABSTRACT OF THE INVENTION Hollow metal microspheres for manufacture of superior high strength light weight structural materials are described.  The microspheres are made by forming a liquid film of molten film forming metal composition across a coaxial blowing nozzle and applying a blowing gas at a positive pressure on the inner surface of the metal film to blow the film and form an elongated cylinder shaped liquid film of molten metal.  A transverse jet directs an inert entraining fluid over and around the blowing nozzle, which produces asymmetric fluid drag forces on the elongated molten metal cylinder and closes and detaches the cylinder from the coaxial blowing nozzle, the cylinder then forming into a spherical shape by surface tension forces.  Quench nozzles direct cooling fluid at the molten metal microspheres to rapidly cool and solidify them.  The hollow metal microspheres may contain a thin metal coating deposited on their inner wall surfaces by appropriate selection of blowing gas.  The metal microspheres can be used to make improved insulation materials and insulating systems or can be used as filler materials in plastics or rubber or compositions thereof or in metal compositions.

Abstract: Abstract A frequency synthesized transceiver capable of tuning to a plurality of communication channels is disclosed.  The transceiver includes a receiver section and a transmitter section which are coupled to the synthesizer which generates the appropriate injection signals to achieve tuning. The frequency synthesizer includes a multiposition switch which accesses various addressable memory locations in a programmable read-only memory where the appropriate divisors are stored to cause tuning of the synthesizer to the appropriate communi-cation channel.  A zone selector switch enables grouping and easy retrievability of channels.  The divisors are supplied to a single synchronous binary swallow counter which works in conjunction with a dual modulus prescaler to monitor the frequency output of the voltage controlled oscillator.  A programmable divider coupled to a reference oscillator source is compared with the output of the synchronous counter in a digital and analog phase detector.  The phase detector supplies signals through a loop filter to apply the appropriate voltage to the voltage controlled oscillator.  The phase detector includes means to rapid advance the voltage controlled oscillator to cause frequency tuning.

Abstract: 49,605 ABSTRACT OF THE DISCLOSURE A solid state load protection system having an inverse time delay circuit.  A current sensing function is utilized  so  as  to produce  an  output  current which is proportional  to  the  current  in  an electrical  circuit. Attached to the current sensing function is a load resis-tor which converts the current produced by the current sensing function to a voltage which is proportional to the current utilized by the load.  Attached to the load resis-tor is an inverse time delay circuit which serves as an overcurrent  and  timing  function.   The  overcurrent  and timing functions monitors the level of voltage from the load  resistor  initiating  a time-out  sequence when the voltage across the load resistor, which is proportional to the current utilized by the load, exceeds a predetermined level for a predetermined period of time.  The overcurrent and timing function utilizes two diode paths for prohibit-ing the charging or discharging of a capacitor during a normal or overcurrent condition, respectively.  Encircling the connections to the capacitor is a guardband for mini-mizing impedances from associated circuitry which affect the  timing of  the  inverse  timing  circuit.   During  an overcurrent  condition,  the  capacitor  charges  up  to  a specific value initiating a trip signal which is sent to an output function.  The output function upon receiving a trip signal causes a light-emitting diode to conduct and also  deenergizes  a  contactor  through  which  a  current source is connected to a load.

Abstract: ABSTRACT            SAFETY DEVICE FOR LADDERS.      The device is a substantially rectangular frame which can loosely girdle a ladder for sliding movement along the ladder and across the ladder from front to back,   The frame has a U-shaped abutment 15 in one longer side 12; this abutment lies at the front side of the ladder and extends towards the ladder.   When the device is moved rearwards so that side 12 abuts the front of the ladder, the abutment 15 extends between the ladder stiles 21 into the longitudinal plane of the rungs 22.    The device has a spring clip 14 in its rear side 13 and can be attached to a person's belt or harness.   In use the person can move up and down the ladder with the safety device hanging forwards (A) so that the abutment does not engage the rungs.   If the person slips his movement will draw the device rearwards and bring the abutment into the space between two rungs (B).   A short downward movement of the device will then bring the abutment to overlie the lower rung (C) and arrest any further downward movement of the device and of the person attached to it.
