Title: Monitoring system for determining the heavy water content of air
IPC: G21C17/022
Filed: 1959-05-01
Abstract: 865,433. Infra-red absorption measurement. ATOMIC ENERGY OF CANADA Ltd. May 1, 1959 [June 2, 1958; Jan. 27, 1959], No. 15027/59. Class 40(3) A monitoring system for providing an indication of the heavy water content of air comprises means for condensing water vapour from the air, means for collecting the condensate, and means for estimating the heavy water content of the condensate by measuring the degree of absorption of infra-red radiation in the neighbourhood of the wavelength of 4 microns, the absorption wavelength of the deuterium oxide molecules (D 2 O and HDO). The infra-red analyser may be the type described in U.S.A. Specifications 2,767,321 and 2,754,424 in which the infra-red absorptions of two light paths are compared with the aid of differential-pressure gas detector operating a capacitor to produce an electrical output. One light path includes a liquid cell containing ordinary water with the normal content of heavy water, and the other includes a cell through which is passed the condensate. For the purpose of the present invention, the normal cell windows of quartz are replaced by synthetic sapphire to allow the transmission of a wavelength of 4 microns, and the detector gas is replaced by deuterated ammonia or sulphur dioxide which absorb at a wavelength of 4 microns. The system of the invention determines directly the deuterium oxide part of the heavy water; the tritrium oxide part may be derived from a knowledge of the tritrium to deuterium ratio of the source providing the heavy water in the air. The arrangement for condensing the water vapour may be as shown in Figs. 7 and 8 where the air to be tested is taken in by a compressor 1 and first raised to a pressure of 5-10 atomospheres. Thereafter it is cooled by passage through first and second heat exchangers 2 and 3 to cause condensation of the water vapour. The water and air are separated in unit 4, which is constructed as shown more fully in Fig. 8, the air passing out through a pipe 8 whilst the water passes to the infra-red analyser 11 through a sintered glass disc 9 which serves to remove air bubbles. A pipe 16 by-passes the glass disc to equalize the pressure on each side and eliminates any tendency for air bubbles to be forced through the disc. Water from the bottom of the analyser 11 passes through a valve constriction 17 and is ejected from the apparatus via valve 19 by air flowing through pipe 19. The majority of the air however passes to a device 13 which adds oil droplets to aid lubrication and is then employed to do work in an air motor 14 driving a fan 15 for the first heat exchanger, the resulting cooled air being used for cooling in the second heat exchanger 3. A modified arrangement, Fig. 1 (not shown), dispenses with pipes and valves 17-19 and includes a filter before oiler 13 constructed as described in U.S.A. Specification 2,726,732 to remove the water.

IPC: D04B11/00
Filed: 1964-04-11
Abstract: 1,044,742. Knitting-machines. GEORGE WOODCOCK & SONS Ltd. April 9,1965 [April 11, 1964], No. 15068/64. Heading D1C. A straight-bar machine having a series of needles frictionally held in a needle bar so as to be capable of selection for colour patterning by means of sliders 8 and pattern drum mechanism as described in Specification 1,001, 591, is provided with elements 4 mounted to be capable of adjustment with the selvedge stop mechanism for the yarn carriers and for slidable movement to engage above the needles 1b extending beyond the operative selvedge needles so as to retain these needles 1b in an inoperative lowered position to avoid the yarns from the carriers engaging them. In addition to the elements 4, members 10 are provided which are secured to a slide 5 on which the elements 4 are mounted to be projected adjacent the end selvedge needle when the elements 4 are projected to engage above the yarn extending from the carrier to the selvedge needle and ensure that the selvedge loops are held down when the selected needles rise. The elements 4 are projected beneath the sliders 8 and are thereby supported when the needle bar is raised. The slide 5 at each end of the row of needles supporting the element 4 and member 10 is slidably controlled from the cam shaft of the machine through a pivoted arm 7. The slide 5 rides on a block 6 which is secured to bars 26, 27 attached to a screw nut 24 which is adjusted by pawl and ratchet mechanism controlling the selvedge stops so that any variation in the selvedge stops has corresponding effect on the needle controlling elements 4.

Title: Improvements in the manufacture of carbon coated resistors
IPC: H01C17/20
Filed: 1943-09-14
Abstract: 568,285. Resistance coatings and deposits. PHILIPS LAMPS, Ltd., HOLMES. T., and HUTCHINSON, W. P. Sept. 14, 1943, No. 15069. [Class 37] Carbon resistors are manufactured by passing rods of refractory material through a rotating tube within which hydrocarbon cracking is performed to produce a coating of carbon on the rods in their passage through the tube, the rods while within the tube being rotated. by contact with its inner wall. The rods 11 of steatite, porcelain, glass, silica, &c. are fed by gravity from a hopper 10 and are introduced singly and in succession into the furnace tube 1. by a pusher 12. This is reciprocated by a rocker arm 17 actuated by a cam 16 which is driven from a shaft 15, the drive of which is derived from a motor 13 through reduction gearing 14. The furnace tube 1 consists of refractory material such as silica, glass, steatite, or porcelain, and is of an internal diameter larger than but less than twice the diameter of the rods 11. The tube 1 is continuously rotated by a gear train 18. Adjacent to its outlet end the tube 1 is supported in a ball or roller bearing 3. The hydrocarbon gas to be cracked is introduced into the furnace tube 1 at its delivery end by way of a pipe 7 connected to a supply pipe 6. The pipe 7, which may be of silica or nickel, is of considerably smaller diameter than the tube 1 and extends to a point 8 in the cracking zone. The methane or other gas to be cracked is mixed with a much larger volume of nitrogen or other inert gas. The exit from the pipe 7 may be so disposed as to impart a swirling motion to the emerging gas. The rotating tube 1 is surrounded by a concentric stationary tube 4 of refractory material on which the furnace heating winding is wound. The heater windings may be sectionalised into three parts, a central zone which heats the coating zone of the furnace, a pre-heating zone, and an after-heating zone. The rods may thus be caused to enter the coating zone at a higher temperature than the furnace tube in this zone so that carbon is deposited on the rods rather than on the furnace walls. The furnace tubes 1, 4 are enclosed in a casing 5 packed with heat insulating material. The coated rods on leaving the furnace are received by a chute 9 which delivers them to a receptacle 19. The coated rods may have their resistance value adjusted by grinding away a helical channel and end connections may be made by binding with tinned copper wire and dipping in solder or by fitting metallic end caps. The finished resistances are protected by a lacquer coating.

Title: Improvements in and relating to filters
Inventor: JONES HUGH ALFRED
IPC: B01D35/02
Filed: 1952-06-16
Abstract: 739,485. Filters. JONES, H. A. June 16, 1953 [June 16, 1952; Jan. 20, 1953], Nos. 15106/52 and 1602/53. Class 46. A coupling member for a filter assembly is adapted at its ends to be connected to the respective mouths of two containers, the connecting parts of the ends being identical, there being an internal apertured wall between the ends forming an abutment for the container mouths when connected, and an axially-extending portion between the aperture or apertures in the wall and the adjacent connecting part of the coupling. In the form shown in Fig. 2 a coupling member 21 having a knurled portion 10 is interiorly threaded at each end for connection with a bottle 1 for receiving the filtrate and a bottle 2 which in use contains the liquid to be filtered. On assembly a Seitz filter pad 9 is interposed between the bottle 2 and an apertured dividing wall 12 of the coupling, the filtrate being prevented from reaching the outer wall of the bottle or coupling by a tube 14. The tube 14 may be open at the top and have a bottom portion provided with the holes 13; in that case the wall of the tube may be inclined upwards and outwards to enable a larger area of the filter pad 9 to be used, Fig. 5. The pad may be supported by a disc of fine wire gauze or, as shown in Fig. 5, the pad may be domed to resist collapse and a packing ring 16 of triangular section provided. In Fig. 6 a thin membrane filter disc 17 can be used without its being distorted by the twist of the bottle in screwing the parts together since a tongued metal ring 18 engaging with a slot 19 in an end 4 of the coupling member 21 is inserted between the disc and the bottle 2. The coupling member may have external lugs or pivot pins to engage corresponding parts in a centrifuge. In use the coupling member is screwed onto an empty specimen bottle and the assembly sterilized in an autoclave. The sterile unit is then screwed onto the bottle containing liquid to be filtered and the whole put into a centrifuge so that the empty bottle will swing outwards during centrifuging and receive the filtrate.

Abstract: 452,173. Axles for motor vehicles. MICHELIN & CIE, Clermont-Ferrand, Puy de Dome, France. May 24, 1935, Nos. 15217 and 15298. Convention dates, July 30, 1934 and Oct. 25, 1934. [Class 79 (iv)] [See also Group XXXII] A rail or road vehicle suspension comprises an axle which has a substantial resistance to bending transversely but is capable of twisting to a considerable extent, and is rigidly connected at each end to a support member which is also strongly resistant to bending in a vertical plane, but can both twist and flex horizontally, the inner ends of the support members being attached to the body of the vehicle so as to permit angular movement in a vertical plane with respect to their points of attachment, and tie-bars connecting the axle and the chassis or body. The axles are formed with a cross-section of small area with a periphery of considerable length so as to allow the necessary twisting. A large number of cross-sections are shown, of which Fig. 3 showing four assembled angle-irons, Fig. 5 showing a flattened tube, Fig. 7 showing a channel-section with unequal arms, and Fig. 11 showing a bent tube, are typical examples. Fig. 21 shows an axle of this kind having support members 5 rigidly secured near its ends, and pivotally connected at their other ends to a flexible torsion bar 8 which is anchored to the body at 9 so that the two ends can twist when transmitting strain to the rods 5. Various arrangements of tie bars 13 also arc shown. Figs. 18 and 20 are examples of sections of support members 5 which may be used. As an alternative the rods 5 may be connected directly to the body 10 with springs or rubber blocks between their upper surfaces and the chassis.

Abstract: 606.809. Coated wire fabrics; compound sheet materials. BENDIX AVIATION CORPORATION. June 19, 1945, No. 15583. Convention date, June 22, 1944. [Class 140] [Also in Groups XXVI and XXXVI] Electrically conductive sheet material suitable for gaskets consists of a yieldable material 6 such as natural or synthetic or polymerized cashew-nut-shell oil reinforced by a plurality of metallic wires of sinuous or wave-like form which may be interwoven as shown at 7 and 8 embedded therein with the crests of successive curves of the wires exposed on and flush with opposite surfaces of the sheet. If desired, the exposed surfaces of the wire may be flattened as at 10, by grinding away a portion of the metal. The engaging portions of the interwoven wires may be soldered. The reinforcing sheet materials may be made by placing the wire screen between two sheets of the yieldable material, subjecting the screen and sheets of material to heat and pressure thereby pressing the material of the sheets into the wire interstices and also vulcanizing the yieldable material. The bends of the wire in the surface of the composite sheet material are exposed by abraiding the surface of the yieldable material by sanding or brushing. If desired, the yieldable material 6 may be applied to the screen by dipping or by running the screen through calender rolls.

Abstract: 608,131. Super-regenerative valve circuits. BENDIX AVIATION CORPORATION. June 20, 1945, No. 15726. Convention date, April 13, 1944. [Class 40 (v)] In a super-regenerative circuit for continuous wave or modulated C.W. reception, the ratio of modulation to quench frequency currents is improved by providing means for excluding carrier frequency currents from the succeeding detector stage. The Figure shows a selfquenching super-regenerative stage 24 which produces at its grid circuit signals at carrier frequency, quench frequency and modulation frequency. Substantially all the carrier component is developed across R.F. choke 38 while combination 40, 42 presents a relatively high impedance to modulation and quench components which are therefore passed exclusively to the second detector stage 44. In a modification (Fig. 5, not shown), the input tuned circuit is connected between grid and cathode of the super-regenerative stage, with a separate inductive coupling between anode and grid circuits.
