Title: Process and apparatus for disintegration of frangible solids such as mica
Inventor: RUZICKA JOSEF
IPC: B02C19/00
Filed: 1969-03-07
Abstract: 1,268.242. Disintegrating suspended solids. J. RUZICKA. 7 March, 1969, No. 12280/69. Heading B2A. [Also in Division C1] Particulate solids, e.g. mica, glass, silica, asbestos, &c., to be disintegrated are fed, with an inert liquid, e.g. ethanol or water, into the lower region of a substantially circular section chamber 50 and are propelled centrifugally through constricted channels of resiliently variable width to disintegrate the particles, the mixture then circulating upwardly such that fine particles rise and are recovered, while coarse particles settle, and are re-passed through the channels. In a preferred apparatus, mica is fed through a supply tube 53, becoming entrained in the liquid, which is forced centrifugally through spaces between vertical walls 65, 66, Fig. 13, of paddles 55, pivotally supported at 57 on a rotary plate 56. Refined particles rise between vanes 59 rigid with the chamber 50 to an outlet 63, coarse material being recycled over a baffle element 54. Sonic or ultrasonic vibrators 60 may be provided to enhance disintegration. Refined particles may be recovered from the liquid surface electrostatically. An electrode 151, Fig. 14, may be positioned close to the liquid surface, causing charging of the particles, which then jump towards an oppositely polarised electrode 152 spaced laterally of the surface, a series of bins being positioned between the electrodes to collect a series of particle weight fractions; alternatively, Fig. 15 (not shown), particles may be attracted by a charged moving belt. An inert atmosphere may be provided to prevent degradation of the particles.

Title: Improvements in or relating to precious metal articles
IPC: C22C1/04
Filed: 1937-05-03
Abstract: Articles of gold, silver, platinum group metals, or mixtures thereof, or of alloys consisting mainly of one or more of such metals, having pores in the interior but no pores visible to the naked eye on the surface, are made by sintering metal powder, preferably in a reducing atmosphere, the surface of the article being if necessary subjected to mechanical or thermal treatment to remove pores therefrom.  The powder may be mixed with a material such as stearic acid or salicylic acid which volatilizes during the treatment to form pores.  The metal powders used may be made by chemical or electrolytic precipitation. For example, silver powder may be obtained electrolytically using a bath containing 3 per cent of silver nitrate and 1 per cent of nitric acid, with a current density of 30 amperes per sq. ft. at room temperature, the powder being scraped from the cathode every 10 minutes.  In some cases the powder may be preliminarily heated to a temperature such as 400 DEG  C. before sintering.  The surface of the article may be made from slightly finer powder than the interior, and the surface may be afterwards improved by colouring, polishing, or incipient fusion.  Articles such as medals, jewellery, cutlery, plate, and the like may be made directly, or from sheets, rods, bars or wire made according to the process.

Title: Improvements in or relating to method of leaching and felting glass fiber
IPC: C03C25/68
Filed: 1955-05-02
Abstract: 769,375. Glass fibres. THOMPSON FIBER GLASS CO.. H. I. May 2, 1955 [Aug. 2, 1954], No. 12647/55. Class 56 .  Glass fibres are. leached, to form silica fibres, by a continuously flowing aqueous acid solution .,which - passes through the mass of fibres, the temperature of the acid entering the mass being, because of the exothermic reaction, lower than the temperature of the acid leaving the mass, the latter temperature being maintained below the boiling point of the solution. The fibres, either loose or in wads or batt form, but preferably not resin bonded, and of ¥ to 1 inch in length, are placed in the tank 1, preferably in a porous bag, e.g. of a cloth known by the Registered Trade Mark " Dynel." The sides of the bag may be secured to the top of the tank. The fibres are first wetted by water supplied to the nozzle 3 by a pump 19, the wetting causing the fibres to slump with consequential reduction of the interstitial spaces between them. The fibres may now be compressed and other bags containing fibres put into the tank and similarly treated. The water is now drained from the tank and acid is supplied by the pump 6 to the nozzle 3, a further slumping of the fibres occurring in the initial stages of the leaching. The acid solution is returned by a pump 10 to a tank 4 from which the pump 6 takes its suction. The solution is heated by steam jets 25. Specifications 636,893 and 732,733 are referred to.

Upon release, a short-circuiting ground is placed on wire d through a delay-device V. If all the lines accessible to the switches such as W are in use, relay G is released, and a buzzer S is connected to a line initiating a call. An operator may identify the line a, b to which a subscriber wanted for a toll call is connected by depressing the key T of each line in turn until his individual lamp B is caused to flicker.
Patent GB-346183-A (GB)
IPC: G01L7/04
Filed: 1930-04-25
Abstract: 346,183. Combined pressure gauge and thermometer. SCHMIDT'SCHE HEISSDAMPF-GES., 2, Rolandstrasse, Wilhelmsh÷he, Cassel, Germany. April 25, 1930, No. 12762. Convention date, May 21, 1929. [Class 106 (ii).] In a combined pressure and temperature indicator for the heating media of heat transferrers the movements of the indicators according to the non- linear law connecting the temperature and pressure of the heating medium in the saturated condition are brought into relation in such a way that if the heating medium becomes superheated, a departure from such related movement occurs. An electric thermometer 4 of the rotating drum type is connected by a pipe 3 to an extension 2 immersed in the steam flowing through the tube 1 of a heat transferrer. The pointer 8 of the thermometer is rotated by the thermometer drum and moves over a scale indicating e.g. 270‹ C. to 370‹ C. For measuring pressure a Bourdon tube 10 is connected to the medium by a pipe 9 the movement of the free end being transmitted to a spindle 13 by quadrant and pinion in the usual way. A cam disc 18 designed according to the non-linear law connecting temperature and pressure of the saturated medium is fixed to the spindle 13, and has secured to it one end of a band 19 which passes over and is fastened to a disc 20 journalled coaxially with the thermometer spindle and carrying a pointer 21. A disc 24 fixed with the disc 20 has attached to it a band 25 connected to the casing by a spring 26. The transmission between the pressure gauge and thermometer spindle may be through cams coacting with a roller or through levers. The two pointers move in unison as long as the steam in the tube 1 is saturated. If the steam becomes superheated the pointers diverge and as the thermometer pointer 8 is preferably coloured red this is readily noticeable. A lug on the temperature pointer may be arranged to engage the pressure pointer on a predetermined divergence and operate an electric signal circuit. In a second form the pressure gauge and thermometer have a common axis, the spindle of the temperature pointer being hollow to receive the spindle of the pressure pointer. Instead of the movement of the manometer pointer being brought into agreement with the temperature pointer, the reverse may be the case. In a third form the spindles 48, 50, Fig. 5, of the pressure and temperature pointers are arranged eccentrically. The pointers 49, 51 intersect continuously on the arc 52 so long as the steam is saturated. The temperature pointer 51 is cut away so that the right-hand edge is displaced from its centre line and so with normal movements does not come into contact with a pin 54 arranged in the centre line at the end of the pressure pointer. Contact occurs when the temperature pointer moves forward relatively to the other upon superheating taking place. By connecting the pointers in an electric circuit 55 with a bell 56, contact between the pointers may be made to operate a signal.

Title: A new and improved water flushing system
IPC: E03D1/12
Filed: 1933-05-02
Abstract: 404,844. Syphonic-discharge waterwaste-preventers. THOMPSON, J., 59, Frere Road, Durban, South Africa. May 2, 1933, No. 12786. Convention date, March 15. [Class 26.] An auxiliary cistern 2 is mounted above the ordinary cistern 1 and connected by a large bore pipe 3 the delivery end of which is normally closed by a valve 12 mounted at the end of an arm 11 which branches off from the arm 10 carrying a float 8. The arm 10 is connected to a valve 7 connected to the water supply pipe 6 and provided with a pipe 9. When the tank 1 has been emptied, water flows from the pipe 6 through the valve 7 and pipe 9 into the cistern 1 from which water overflows by the pipe 13 into the tank 1. Water rises in the syphon 15 until the aperture 46 is covered, imprisoning air in the syphon. As the water rises in the tank 1, the float 8 rises and lifts the valve 12 and water rushes into the tank 1 by the pipe 3 from the tank 2. Mounted in the flush pipe 4 which connects the tank 1 or through a water seal 17 with the pan 5 is a push-button air valve 18 comprising a casing 19 having ends 20, 21 which are screwed into the pipe 4. Inside the casing is mounted a valve 22 which slides in a housing 36 and is connected by a spring- controlled rod 23 to a push-button 24, and is normally seated against the part 39. When the button 24 is pressed, the valve 22 is disengaged from its seat and air passes from the flush pipe 4 by a pipe 28 through baffle chambers 41, 42 connected by an opening 44 into the interior of the valve seating 39 and thence to the atmosphere by an aperture 37. The pressure in the boll 15 is therefore released and syphonic action commences and continues until the tank 1 is emptied. A catch 25 pivoted to the housing 36 retains the valve 22 in its open position until the air under pressure in the pipe 4 has escaped. The stream of water down the pipe 4 impinges on the disc 26 mounted on the catch 25 and trips the latter allowing the valve 22 to return to its closed position. The cistern may be also used for urinals or latrines.

Abstract: 592,475. Barrels for firearms. WERNLI, M. May 22, 1945, No. 12838. [Class 92 (ii)]. The barrel of a firearm is subdivided into two parts 1, 4 by means which provide the required jointing pressure and are resilient, so that the release, removal and replacement of one of the barrel parts is effected by overcoming the resilient pressure. As shown in Fig. 4, the rear part 4 has threaded on it a ring 7 which holds in place a ring 6. Around the ring 7 are fitted 'a number of screws 10 which pass through holes in a member 9, and between this member and the heads of the screws are fitted resilient discs 15 which serve to urge the member rearwards against a shoulder 2 on the barrel part 1, thus exerting the required pressure to hold together the two conical surfaces of the barrel parts. The ring 6 also has a number of holes 13 fitted with pistons 17 and supplied when desired with pressure fluid by a conduit 32, the various holes being connected by a channel in the ring. To remove the barrel pressure fluid is admitted to the holes 13 and the resulting forward movement of the pistons cause their reduced ends 18 to move the member 9 forwards against the action of the discs 15. The barrel 1 can now be removed by first rotating it through 60 degrees, such action bringing spaced lugs on its shoulder 2 opposite spaced recesses on the member 9. A further clamp 20, Fig. 1, may be provided for the part 1, this consisting of a vertically moving jaw which is urged downwards by springs on to the upper surface of the barrel to press the barrel against a ring in a mounting part 22. Release is effected by pistons acted on by fluid pressure, the pistons serving to lift the clamping jaw.

Title: Improvements in ion-exchange processes
IPC: B01J49/00
Filed: 1952-05-21
Abstract: In an ion-exchange process in which a liquid is passed through a static granular bed of either cation-exchange or anion-exchange material and the bed is regenerated from time to time, the material forming the bed is remixed after each regeneration, for example, by blowing compressed air through it to suspend the granules and cutting off the air supply to let the suspended granules settle rapidly. Alternatively the bed may be mechanically stirred.  Examples are given illustrating how the remixing increases the ionexchange capacity of the bed, lowers the concentration (of those ions which are being removed) in the treated liquid, and allows regeneration of the material to be effected with less regenerant.  Specification 662,214 is referred to.ALSO:In an ion-exchange process in which a sugar solution is passed through a static granular bed of either cation-exchange or anion-exchange material and the bed is regenerated from time to time, the material forming the bed is remixed after each regeneration, for example by blowing compressed air through it to suspend the granules and cutting off the air supply to let the suspended granules settle rapidly.
