Title: Improvements relating to conveyors
Inventor: FRIENDSHIP KENNETH FRANCIS MON
IPC: B65G47/51
Filed: 1962-02-02
Abstract: 971,807. Endless conveyers. BURNETT & ROLFE Ltd. March 1, 1963 [Feb. 2, 1962], No. 4090/62. Heading B8A. In a mechanism for filling and sterilizing beer kegs, the kegs 4 pass from an input conveyer 12 on to conveyers 6, 8, 7, 9, arranged in a circuit, there being a row of filling and sterilizing mechanisms 1 adjacent the conveyer section 6 and a similar row 2 of such mechanisms adjacent the conveyer section 7. The entry of a keg 4 to each mechanism in the rows 1, 2 is governed by an interceptor member 24 associated with each mechanism and which normally extends into the path of the associated conveyer 6 or 7 and deflects a keg from the conveyer on to an endless conveyer 18 (Fig. 3) associated with the mechanism. As the keg 4 passes on to the conveyer 18 it operates a withdrawal member 25 so as to cause the interceptor member 24 to be retracted into an inoperative position. The members 24, 25 form a bell-crank pivoted at 26 (Fig. 2). The conveyer 18 carries the key to a position above a platform composed of rollers 34 suspended by arms 30 of a yoke member connected to the piston of a pneumatic bellows member 32. In passing into position over the rollers 34 the keg operates a switch 29 (Fig. 4) carried by the yoke member 30, thus causing pressure to be applied to the bellows 32. The yoke member is thereby lifted so that the keg is brought into engagement with a filling head 3. The latter is formed with a bell-mouth which has a camming action on the keg to move it if necessary forwardly or rearwardly in the direction of the conveyer 18 or laterally on the rollers 34 to bring it into correct alignment. When the sterilizing and filling operation is completed a relay is energized as described in Specification 971,808, and this initiates the lowering of the key back on to the conveyer 18. It then passes to an output conveyer 15. When a keg has passed the withdrawal member 25, the interceptor member 24 is permitted under spring action to move back into its operative position. Another keg can then pass on to the conveyer 18 but if the previous keg is still in filling position, the second keg is held up, slipping on the conveyer 18 by engagement with the raised rollers 34. Kegs 4 continue circulating around the conveyer sections 6, 8, 7, 9 until they find a vacant filling and sterilizing mechanism. Specifications 952,988 and 971,808 are referred to.

Abstract: 324,252. Berkel & Parnall's Slicing Machine Manufacturing Co., Ltd., and Thomas, H. Feb. 7, 1929, Cutting slices in succession.-A device for gripping the foodstuff is positioned at one side of the feed table. As shown, the device is formed similarly to a last slice holder and may be used as such if required. The device comprises a rigid frame 1 - - 3, a flexible front plate 5 secured thereto, shafts 7<a>, 7 which are geared together and carry spikes which project through apertures in the plates 5, and means described below whereby the front plate and the shafts 7 may be displaced into the curved position shown in dotted lines on Fig. 4, to conform with curved pieces of meat. The top shaft 7<a> is journaled in the rigid side members 2, 3 and the bearings for the remaining shafts 7 are linked together in the form of chains 9 which are suspended from the shaft 7<a>. The lowermost har 7 carries quadrants 14, 15 which are joined by a handle 16, 17 and are also attached to links 13 suspended from the top bar 7a. The quadrants have slots 22 with enlarged end portions 25 which receive enlargements on a spring- pressed rod 18. The quadrants are thereby locked in either of two positions, in one position the front plate 5 is straight and in the other it is curved. The pivoted member 28 releases the quadrant from the shoulders on the rod 18. As shown in Fig. 1, the device is pivoted on the pillar 4, is raised for adjustment by the lever 32 and is located by a pin 30 engaging one of a number of holes 31 in the feed table. The device may be thus positioned at an angle suitable to the shape of the meat. When the device is used as a last slice holder, the member 28 engages a stop 34 which maintains the quadrants 14, 15 free, and prevents the device from being used in the curved position and damaging the knife. The spikes for gripping the meat are actuated by the handle 11. The device may be fitted to a display tray, or the substance may rest on the under table of the machine and be drawn across the table by the side gripping device. A band or roller may be fitted in the table to facilitate the feed. The device may have a rack and pawl adjustment on the quadrants 14, 15 to permit adjustment into more than two curved positions. When used as a last slice holder, the device may grip the meat in a curved position, and when the piece becomes very thin, the holder is straightened out. The front plate 5 is made to flatten by its own resilience, but any flexible or jointed plate may be substituted therefor, or the plate may be dispensed with.

Title: Production of colloidal solutions
IPC: C01B33/141
Filed: 1952-02-15
Abstract: Colloidal solutions of oxides of metals or metalloids are produced by decomposing a suitable volatile compound in the gaseous state by means of a gaseous oxidizing or hydrolysing agent, recovering the oxide in pure form and dispersing said oxide in a liquid medium by mechanical means such as intensive stirring or wet grinding.  In a preferred embodiment steam is formed in situ by burning hydrogen or a hydrogen containing gas with which is mixed the volatile compound, if desired with diluent gas such as nitrogen.  The oxide particles may be cooled before recovery by electrostatic precipitation, settling, filtering or deposition on cooled surfaces.  In examples silica and titanium dioxide aquasols are formed from the tetrachlorides.  10-25 per cent, silica aquasols of great permanence can be produced in this way.  Alumina and zirconium dioxide sols are also referred to. Additional substances such as protective colloids or electrolytes may, if desired, be added.

Abstract: 843,101. Valves. POWER-GAS CORPORATION Ltd. Feb. 7, 1957 [Feb. 10, 1956; March 29, 1956], Nos. 4153/56 and 9810/56. Class 135. A valve comprises a casing made of two bowlshaped members 1, 2 of pressed metal plate detachably fastened together, as by bolts 3, an inlet connection member 5 and an outlet connection member 4 at least one of which protrudes into the casing, a valve seat 6 carried by or formed on one of the connection members 4, 5 and a valve closure member 7 co-operating with the seat to control or obstruct fluid flow. The bowl-shaped members may each be the segment of a sphere, an ellipsoid or a paraboloid, or such a segment combined with a coaxial cylinder. The connection members 4, 5 may be formed of seamless metal tube, of tube shaped from metal plate, or of cast metal. As shown the valve seat comprises a machined ring 6 welded to the outlet member 4 and co-operates with a similar ring 8 welded to the valve disc 7. The latter slides in a direction generally parallel to the valve seat and is operated by a stem 9 passing out of the dished member 1 and connected with suitable operating mechanism 10 such as the screw and hand wheel shown, or a fluid-pressure operated piston, or an electromagnetic solenoid. As the valve disc closes it is thrust towards its seat by a wedge portion 11 cooperating with a complementary wedge portion 12 on a bridge member 13 secured to the connection member 4. The dished members 1, 2 are sufficiently elastic to ensure a substantially uniform distribution of stress in the casing. In a modification the valve disc 7 has a dished portion with the convex side toward the valve seat and the single wedge portion 11 is replaced by diametrically opposite wedge-shaped projections engaging similar projections on a bar extending transversely of the valve casing. In a further modification, the connection members are formed as seamless tubes and both project into the casing. The valve member comprises a ring with a machined flange and a spherical segment welded thereto, the convex side of the latter facing a seat on the outlet connection member. In a still further modification the valve disc or gate is forced against a valve seat on the inlet connection by co-operating wedge-shaped parts carried by the disc and the inlet connection member.
