Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for determining the location of the liquid surface in a well or bore hole has a source of acoustic pressure pulses coupled to the surface casing so that they are transmitted down the well and reflected by the gas-liquid interface.  A transducer is also coupled to the well to produce an electrical signal in response to direct and reflected acoustic pulses occurring in the well.  A clock pulse source is provided together with a pulse counter for producing one pulse output for a certain number of input pulses and having its input connected to the clock pulse source to apply the clock pulses as input pulses.  The pulse counter is connected to a calibrating device capable of adjusting the number of input pulses required to produce a single output pulse.  Gating circuitry responds to the transducer for starting and stopping the counting of clock pulses by a digital counter and a digital read out device is utilized to indicate the depth to be liquid level in the well.          The source of acoustic pulses is actuated automatically at predetermined times, and the depth to the liquid level and the time are recorded automatically.  The monitor can be used to control the operation of a pump in the well.

Abstract: ABSTRACT OF THE DISCLOSURE        A  particulate material can be dispersed by the application of electrostatic fields.  The phenomena, referred to as "electrodispersion" is the dispersion by an intense electric field of part of a static bed of powder into a stable cloud of rapidly moving particles, and the maintenance of a dynamic equilibrium between the static and dispersed phases.  The density of the dispersed cloud of particles varies with a number of factors, including the field strength and the nature of the powder.         The electrodeposition effect is employed to produce a uniform and durable coating of controlled thickness on the individual particles, by the generation of a vapour of the desired coating - typically a metal or semiconductor material - and allowing the vapour to permeate the dispersed particles.  The electric field ensures that only the particles are coated, and the dispersed particles, having the same charge, repel each other, avoiding agglomeration.          Potential applications include the manufacture of high performance catalysts wherein expensive metals like platinum are vapour-coated onto an inexpensive metal powder.  Other possibilities include the production of graphite-coated metal particles for making self-lubricating metal components such as bearings and shafts, and the manufacture of slow dissolving coatings on pharmaceutical powders.

Abstract: ABSTRACT            The invention is concerned with an actuating system for use in a coke oven having a chamber, a vertical gas offtake pipe provided with a cover and an axially extending main connected to the gas offtake pipe and provided with a seal for sealing off the chamber from the main, for consecutively closing the seal of the main and opening the cover of the gas offtake pipe and actuating the cover and seal in the opposite sense and converse sequence.  The system of the invention comprises a double-arm lever mounted on a shaft connected to the cover, for pivotal movement about the shaft whereby to open or close the cover, the lever having a weight-loaded arm and an actuating arm; upper and lower draw rods interconnected together by means of a pivot pin for pivotal movement in a vertical plane perpendicular to the axis of the main, the upper draw rod having at its upper end and eyelet for guiding the free end of the actuating lever arm and the lower draw rod being connected to hydraulic actuating means for vertically moving the draw rods; guide means for vertically guiding the pivot pin; and a bell crank lever mounted on the pivot pin for pivotal movement thereabout, the bell crank lever having a slotted arm and an actuating arm connected to the seal.          The slotted arm has a longitudinally extending slot for guiding the pin when the slotted arm is in a vertical position and the actuating arm is pivotable about the connection thereof to the seal whereby to close or open the seal.  Downward movement of the draw rods first causes closure of the main seal and then opening of the gas offtake pipe cover, and upward movement of the draw rods first causes closure of the cover and then opening of the seal.

Abstract: TEMPORARY SIGNPOST SUPPORT SLEEVE AND TOOL FOR UNSETTING SAME ABSTRACT A signpost support sleeve comprises an upwardly open upright socket member having a horizontal footplate across the bottom, and a vertical spike on the underside of the footplate. A special unsetting tool is driven beneath the plate to apply a removing force directly to the sleeve. In the embodiment shown, the socket member has a square recess for a square post having a forwardly extending, cantilever cross arm to which an appropriate sign is fastened. The footplate is generally rectangular. It extends cantileverly forwardly and bears foot-like against the ground to keep the post from leaning forwardly under the weight of the cross arm and sign. The unsetting tool comprises an L-shaped lever having a tooth at one end engageable with one of three underside openings along the rear edge of the footplate. The openings on the underside of the footplate serve the dual function of providing drain openings for the socket member recess and providing a choice of seats for the tooth at the end of the unsetting tool. A hammer lug is fastened across the tool behind the tooth. The lug can be hammered to drive the tool beneath the footplate to align the tooth with one of the openings. The sleeve is then lifted out of the ground by prying the tool about the hammer lug acting as a fulcrum against the ground.
