Title: Machine for dispensing fluid material into containers
IPC: B65B3/32
Filed: 1971-09-01
Abstract: 1383506 Filling containers BRISTOL PACKAGING MACHINES Ltd 26 Oct 1972 [1 Sept 1971] 40732/71 Headings B8C and B8T A dispensing device for fluid material, e.g. margarine comprises a supply conduit 60 having a dispensing port 62 and a return port 63 leading into a return conduit 61, a valve 65 for closing both ports or for opening either port, and means for supplying successive quantities of material through conduit 60, and opening either the dispensing or return port in dependence on the presence or absence of a container 16 beneath the dispensing port. The containers 16 pass' down a shoot 21 provided with air jets 22 to a flexible helical spring 24 which presses the containers into compartments 15 of a conveyer 10 which feeds each container under one of a plurality of dispensing arms 35 rotating about a supply pipe 34. The valve 65 in each arm is connected to a gear segment on an arm 69 having a cam follower 70 riding in a cam track 73. In the dispensing zone in which there is a vibrating plate 32 the track is split into two paths 71, 72 and a sensor 30 on sensing the presence or absence of a container in a compartment 15 opens a respective path 71, 72 so that the arm rotates to cause the valve to open one of the ports. A piston 81 is then cammed upwardly to dispense the fluid through the opened port. Between positions 161 and 145 in Fig. 1 the conduit conduit 60 is connected to the interior of the supply pipe 34 to receive further fluid as the piston 81 is cammed downwardly. The lowermost position of the piston is adjustable to adjust the quantity dispensed. From the return conduit 61 the fluid passes around a piston 92 into a return pipe 91, the piston 92 permitting a bleed from the supply pipe 34.

Title: Improvements in or relating to devices for removing and replacing bearing-chock assemblies
IPC: B21B31/08
Filed: 1959-12-02
Abstract: 874,498. Wagons adapted to transport special loads. UNITED ENGINEERING & FOUNDRY CO. Dec. 2, 1959, No. 40947/59. Class 103(4). [Also in Groups XXII and XXIII] A device for removing and replacing rollchocks for the journals of roll-shafts comprises a platform adapted to be moved axially of the shaft, a platen mounted on the platform and provided with a chock-supporting surface, means for vertically-adjusting the platen and pressure applying means adapted to exert pressure on the chock to move it axially of the shaft. Rolls R are received on a rack 13 with bearing chocks BB<SP>1</SP> still in position on the journals. Each chock is removed from the roll by a device 11 comprising a carriage 14 movable longitudinally of the rack on rails 12. The carriage 14 supports a further carriage 18 for movement axially of the roll R on I-beam tracks 84. The position of the carriage 14 is indexed by a pin 15a engaging a socket 15b. With the carriage 14 in position the carriage 18 is moved towards the roll so that a vertically-adjustable and resiliently-mounted platen 33 is located beneath the chock to be removed. The vertical position of the platen 33 together with that of the plate 28 is then adjusted by the screw jacks 25 operated through a chain-drive by a handwheel 57 to bring the platen 33 into engagement with the underside of the chock. With the carriages in position and the platen 33 adjusted arms 39 pivoted to the carriage 18 are brought into engagement with the face of the chock and links 53 are attached to the upper ends of the arms. The links 53 are in turn attached to a pedestal 43 on which is mounted a screwjack 47 swingable into and out of its operating position on a pivoted frame 46. On operation of the screwjack 47 the pad 51 engages the end of the roll and the carriage 18 is displaced away from the roll and moves the chock with it. If the chock is not tightly fixed the arms and jack need not be used. To replace a chock the latter is mounted on the platen 33 with the carriage 18 in the retracted position, the platen being vertically adjusted for correct alignment with the roll-journal whereupon the carriage 18 is moved towards the roll to engage the chock.

Abstract: 867,963. Dispensing pumps. LEWIS BERGER & SONS Ltd. Dec. 2, 1959 [Dec. 15,1958], No. 41021/59. Class 102(1). A piston 5 is axially but non-rotatably movable in a sleeve 4 rotatably mounted in a housing 1. A plug 8 engages a groove 10 in the sleeve 4 to prevent axial movement and the end 22 is engageable with longitudinal grooves 23, 24, 25 in the piston 5, which grooves are of different lengths and are joined to a common longitudinal groove 29 at one end by grooves 30, 31, 32 and a common circumferential groove 26 at the other end so that the piston 5 may be locked in its inner position or withdrawn to the extent allowed by one of the grooves 23, 24, 25 after rotating the piston, during which time the interior of the sleeve communicates with a passage 2 leading to a reservoir, Further rotation of the piston causes relative movement of the end 22 of the pin 8 in one of the grooves 30, 31, 32 until the end enters the groove 29 and at the same time the sleeve 4 closes the inlet 2 and opens an outlet, thereafter the piston 4 may be pushed in to deliver the selected volume of liquid. The pump is used for dispensing coloured paint into a base paint.

Title: Alkali metal salts of carboxymethyl cellulose
IPC: C08B11/12
Filed: 1965-09-29
Abstract: In a process for preparing an alkali metal salt of carboxymethyl cellulose (CMC), alkali cellulose is etherified by an agent comprising at least 80 mole per cent of monochloroacetic acid (MCA) and up to 20 mole per cent of dichloroacetic acid (DCA).  The MCA and DCA may be added together or separately.  The etherification may be carried out in a 2-phase liquid system containing a water-miscible aliphatic alcohol, and comprising aqueous alcohol as one phase and inert water-immiscible organic liquid/ alcohol mixture as the other phase (see Specifications 772,183 and 1,108,282).  Specified alcohols are ethanol and isopropanol.  Specified water-immiscible liquids are benzene and toluene.  The etherification may also be effected by steeping cellulose in alkali for 1-3 hours at 0-30 DEG  C., in a mixture of (1) an aliphatic alcohol (2-4 carbon atoms), dioxane, and/or acetone, (2) methanol, ethanol or acetone, (3) water, adding etherifying agent, and heating.  The alkali metal salt of CMC of the invention is formed as gel particles (5-60% of the total CMC product) which are too large to pass a 325 U.S. Standard mesh screen.  This material has an infra-red adsorption band between 5.7 and 5.9 microns, is insoluble in aqueous 5% sodium hydroxide at 20-30 DEG C., but soluble in such alkali at above 80 DEG  C., and forms an aqueous solution capable of maintaining substantially constant viscosity at constant rates of shear for at least 30 minutes.  The properties of the CMC may be modified by adding water to the etherification slurry.ALSO:Carboxymethyl cellulose (CMC) which contains gel particles and exhibits an infrared adsorption band between 5.7 and 5.9 microns is added to orange juice to prevent the pulp therein from settling.  In an example, 0.05%-0.15% of CMC is added to orange juice.

A P-type zone in a body of Group IV semi - conductor material is produced by heating the body and a source of impurity having precipitated thereon a monoxide of the semi-conductor material, in a treatment vessel. Fig. 2 shows a scaled quartz vessel 4 containing discs 6 of silicon and an impurity source 5 consisting of a drop of gallium in a piece of silicon; the vessel 4 is shown in two positions in a furnace the temperature along the furnace being indicated by the temperature curve. As shown in position I, the silicon discs are at 1230 C. and the gallium source at 1050 C. while in position II the discs are still at 1230C., but the gallium is at 950 C. In the process, the vessel 4 is inserted into the furnace in position 1 and silicon monoxide forms at the quartz/silicon interface and precipitates in the region which is at 1050 C., i.e. on the gallium. After a period of 10 minutes to 1 hour the vessel is moved to position II for 30 to 48 hours when gallium diffuses into the silicon. The process may be carried out in vacuo or under a protective gas. The Specification also refers to aluminium and boron as impurities and germanium as semiconductor. The monoxide acts as a transport medium and facilitates accurate control of the diffusion process.
