Title: Radiation measurement instrument
Inventor: BAURMASH LEONARD
IPC: G01F23/288
Filed: 1968-04-25
Abstract: 1,222,586. Photo-electric measurement of volume. NORTH AMERICAN ROCKWELL CORP. April 25, 1968 [April 26, 1967], No.19702/68. Heading G1A. The volume (or mass) of liquid 18 in a container 20 is measured by photo-electric apparatus comprising radioactive sources 12, 14 and a detector 10 of secondary radiation caused by scattering in the liquid of the radiation from the sources. Primary radiation received by the detector would lower sensitivity so that lead shields 22, 24 block direct radiation from reaching the detector. The source material may be a γ-emitting isotope e.g. Kr85 or (for cryogenic fluids) Cs137. The detector is a Geiger counter connected through a pulse shaper 52, producing pulses of uniform height and width, to an integrating amplifier 54 and an indicator 56. The measured value is rendered linearly proportional to the volume by the configuration of sources and detector (d 1 >d 2 ) in the container 20. When using a spherical container, Fig.3 (not shown), the source is bent appropriately at points along its length. Sources may be spaced around the detector in cruciform, triangular or circular configuration. The indicator is zeroed when the container is empty, since a small count is obtained from the inside walls of the container.

Title: Treatment of solids with liquids
IPC: B01F7/08
Filed: 1956-06-26
Abstract: Comminuted, preferably powdered, solid materials are reacted with a liquid, the solid having a lower specific gravity than the liquid or being otherwise such that it floats on the liquid, by moving the solid through a substantially horizontal chamber which contains a body of the liquid and mixing the solid with the liquid, a direction of flow being imparted to the liquid different from the direction of <PICT:0837428/III/1> <PICT:0837428/III/2> motion of the solid.  In the apparatus shown in Fig. 1, solid enters the chamber at 3 and is conveyed by a worm 2 to a weir 4 where it is discharged.  Liquid enters by spray pipes 5 and, passing transversely across the path of the solid, leaves the apparatus by outlets 6.  In the form shown in Fig. 2, solid is conveyed from inlet 8 to an outlet weir 9 by paddles 11, the inclination of which is variable.  Liquid passes in countercurrent to the solids from inlet 7 to an outlet below a quiescent chamber 10.  The liquid level is maintained below that of the outlet weir 9 over which solid is discharged by a paddle wheel or a screw conveyer.

Abstract: 984,282. Filters for liquids. J. P. BRYDON. June 5, 1961 [June 6, 1961], No. 20225/61. Heading BID. Two filters are disposed in parallel and are associated with two valve assemblies so arranged that in one position one filter is passed in reverse through the other filter to backwash it, while in the other position the functions of the filters are interchanged. The locations of the inlet, and of the outlet (to waste), are independent of the valve positions. A pump may be provided between the two filters, and the arrangement is such that the direction of flow through it is also independent of the valve positions. In Fig. 5 unfiltered liquid is introduced at an inlet behind a valve member 16, flows from passage 6 through a filter element 2a to a passage 5, and is discharged at 14 behind a valve member 17 to the inlet of a pump (not shown). From the pump the filtered liquid is introduced at an inlet in front of valve member 17 and is deflected thereby along a passage 4 to flow in reverse through a filter element in filter 1 to a passage 3, whence it is discharged to waste past valve member 16. The valve members are secured to a common shaft 20 which may be moved to transpose the valve members by an increase in pressure differential across the filter element in use. Such increase may be sensed by a hydraulic control system 30, Fig. 6, which operates a hydraulic motor 21, Figs. 5 and 6, having a rotor 24 keyed at 25 to shaft 20. Instead of the hydraulic motor there may be provided on shaft 20 a toothed pinion driven by an electric motor through a worm gear, the motor being set in operation by a mercury switch tilted by a flexible diaphragm on attainment of the necessary pressure differential. A disc with conducting surfaces constituting a holding switch is also carried by the shaft 20, Figs. 2 and 3 (not shown). In Fig. 7, each valve assembly consists of two pairs of hydraulically-operated lift valves, the valves in each pair being so arranged that when one is open the other is closed. They may be operated by a control system 30 identical with that in Fig. 6. The invention may be applied to the bilge system of a ship so that the filters, probably being in inaccessible locations, may be cleaned in situ.

Abstract: 167,183. Nivet, P. July, 29, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Tyre attachments to rims.-Single-tube pneumatic tyres are fixed to the rim by bands of linen, hemp, wire or other material engaging the sides of the tyre and possessed of sufficient elasticity to enable them to be stretched over the edge of the rim. As shown in Fig. 1, the securing- band a is located between the fabric layers b, b<1> of the tyre. Fig. 2 shows an alternative form in which the band a is placed outside the tyre, the tyre being folded around it. In a further modification the edges of the tyre are inturned, securing the band a in a similar manner to that shown in Fig. 2. The tyre is sewn along its abutting edges. When metal wires are used, these have a sinuous form, or may be in the form of coiled springs with" long coils," and are covered with rubbered cotton. Several wires may be used together so that the bends of one wire enter those of the other. When linen or like bands are employed, they are composed of adhesive threads twisted together and compressed by the air pressure. One or more of the threads may be " taken up " at the seam between the tyre edges.
