Abstract: ABSTRACT Disclosed is a switch unit for an electric immersion heater for mounting on the wall of a liquid heating vessel, the switch unit including thermally responsive means sensitive to boiling liquid on a body of the switch unit in a position for exposure, in use, to vapour emerging from the vessel.  The thermally responsive means comprises a snap-acting bimetallic actuator comprising a member of sheet bimetal having an aperture with an outer perimeter and an inner perimeter defining a tongue free at one end inter-mediate two lobe portions of the aperture.  The inner  perimeter and arcuate portions of the outer perimeter smoothly merge at rounded ends of the aperture adjacent the tongue root.  The tongue is, at least in part, generally centrally disposed with respect to the member, the member having been deformed in a die pressing operation to conform in shape to a die of domed configuration, the domed area being such as to reverse its curvature with a snap action with change in temperature, and the width of the domed area being greatest in the region of the tongue root.  An overcentre spring mechanism couples the bi-metallic actuator to a movable contact of an electrical switch for opening and closing the switch, the overcentre spring mechanism being movable between a first position in which the switch is closed and power can be supplied to the immersion heater and a second position in which the switch is open for interrupting the supply of power to the immersion heater.  A lever of the overcentre mechanism is pivotally mounted on the body and a spring of the over-centre mechanism is mounted between fulcrums provided by the lever and the body so that the spring biasses the lever into direct or indirect engagement with the bimetallic actuator in the first position of the overcentre mechanism.

Abstract: Case 790303 ULTRA HIGH SPEED PRESENSITIZED LITHOGRAPHIC PLATES Abstract of the Disclosure Presensitized lithographic plates having a diazo layer are prepared such that they exhibit a photospeed rendering them suitable for ultra high speed operations including use within laser platemaking systems. These ultra high speed plates have a diazo layer that is exceedingly thin while still being generally uniformly distributed throughout the plate area. The process includes extracting a significant quantity of diazo material from a diazo layer on a presensitized plate substrate. Plates thus formed are useful in laser exposures for facsimile transmissions, as projection plates, as camera back plates, for step and repeat plate work, and where low intensity light sources are used in conjunction with very large plates.

Abstract: ABSTRACT      A down hole well drilling tool, e.g., a turbodrill, which is connected to a string of drill pipe as a rotating shaft for driving a drill bit which may be a rotary bit or a high speed solid head diamond bit.  The turbine section has rotor and stator blades which are crescent-shaped in cross section.  The bearing shaft is provided with chevron rotary seals positioned below the rotary bearings carrying both radial and vertical thrust.  Fluid lubricant fills the space from the rotary seals to a predetermined level above the bearings.  A piston seals the lubricant chamber and is pressurized by drilling fluid (i.e., mud) flowing through the tool.  A layer of lubricant fluid over-lies the first piston and has a second piston covering said fluid and transmitting pressure from the drilling fluid to the lubri-cant fluid surrounding the bearings.  Means is provided to give an indication, at the well surface, of loss of lubricant in the turbodrill.  Means is provided to cause the vertical thrust to be carried on the bottom vertical thrust bearings, after the top vertical thrust bearings are worn, and thus extend the drilling life substantially.  Another optional feature provides for bal-ancing the pressure across the bearing seals.  This is accom-plished in one form of the invention by providing pump means operated by the drilling motor to pump drilling mud away from the bearing seals.  In another form of the invention, the flow of drilling fluid is divided into two streams, one of which rotates the drill bit, and the other of which passes through the drill bit.  The pressure drop across the drilling motor equals the pressure drop across the drill bit, thus balancing the pressure on the bearing seals.

Abstract: RCA 75,663 ABSTRACT     A circuit for generating a composite timing signal in a television receiver comprises a gate pulse generating circuit, and a voltage divider coupled across a fixed voltage source.  The composite signal comprises a first pulse developed at an output of the voltage divider during television signal horizontal and vertical blanking intervals, and a second pulse developed by the gate pulse circuit during a portion of the horizontal and vertical blanking intervals and superimposed on the first pulse.  A switching device coupled to the voltage divider responds to horizontal and vertical timing control signals applied via signal coupling circuits for enabling the voltage divider to develop the first pulse.          The level of the first pulse is predictably determined by the voltage divider substantially independent of the amplitudes of the horizontal and vertical timing signals, and the values of circuit components included in the timing control signal coupling circuits.

Abstract: TITLE      A method and apparatus for cleaning gas-contaminated particulate material by multiple passes of the material through a vacuum chamber and between containers which are cycled or flip-flopped through an arc of 180°.                         ABSTRACT An apparatus and method are disclosed for cleaning gas-contaminated particulate material such as powder metal.  The gas-contaminated particulate material is subjected to an electric field in the vacuum chamber to electrically charge the gaseous contaminants and cause separation of the gaseous contaminants from the powdered metal to facilitate the removal of the gaseous contaminants from the vacuum chamber.  A support means supports containers for initially positioning the first container above the second container to allow the particulate material to flow from the first container through the vacuum chamber and into the second container and for thereafter rotating the vacuum chamber and the first and second containers while they are connected together to reposition the second container above the first container to allow the particulate material from the second container to return in the opposite direction back through the vacuum chamber to the first container.  This flip-flop concept is the distinguishing feature of the subject invention.
