Abstract: 621,515. Centrifugal compressors. DAVIS, C. A.. PLUMB, R. C., DAVIES, D. O., and CORBITT, R. W. Sept. 27, 1946, No. 28948. [Class 110(i)] A centrifugal compressor rotor has a single rotating inlet guide vane associated with each rotor vane and is characterized in that each guide vane has a section such that its centre of torsional vibration is situated substantially coincidental with or up-stream of the aerodynamic centre of pressure. The guide vanes 22 may be of aerofoil section and various arrangements are described to avoid turbulence between the trailing edge 17 of vanes 22 and the inlet edge 20 of the rotor blade 21. The thickness of the trailing edge of the guide vanes may be equal to that of the leading edge of the rotor blades. Specification 619,236 is referred to.

Title: Improvements in activating treatments of bentonites and subbentonites for filtering and decolorizing purposes
IPC: B01J20/12
Filed: 1935-10-21
Abstract: Bentonites are activated by first boiling with diluted sulphuric or hydrochloric acid, draining, and washing with water, as is usual, and then neutralizing to any degree by a solution of caustic soda or other base.  The product may be used for filtering and decolorizing not only mineral but also even edible vegetable or animal oils and fats, e.g. linseed, cottonseed, peanut, lard and tallow oils, and for reclaiming used lubricating-oils.

Abstract: 1,194,676. Filtering press. G. & J. WEIR Ltd. 39 Sept., 1967 [29 June, 1966], No. 29093/66. Heading B1D. A filtering press for fruit pulp comprises a cylindrical housing 1, lined by an inflatable tube 3, and respective cloth filtering tubes 9, 10 of which tube 9 lines tube 3 and tube 10 covers a core 2. Pulp enters the space between tubes 9, 10 through inlet 8, then tube 3 is inflated through opening 18 and filtrate passes through the walls of tubes 9, 10, into grooves formed on tube 3 and grooves or perforations in core 2, being discharged respectively from outlets 15, 14. The tube 3 is deflated through outlet 19 and hydraulic jacks 23 are extended to lower core 2 out of fixed cylinder 1, scraper 25 then removing cake from tube 9 as the core descends. Before the core is raised, scraper brush 26 is advanced radially inwards so as to engage tube 10 to remove cake therefrom when the core 2 is raised. A lower jack 27 urges core 2 upwards forcing plate 20 thereon to sealingly engage plate 7 in the closed position. In a simpler version (Fig. 3, not shown) a cloth filtering bag (41) is draped in re-entrant fashion over fixed core (32), and cake is removed from the bag by lifting it manually from the housing (31) after tube (33) has been deflated. In either embodiment the inflatable tube could be replaced by a bag.

Abstract: 409,292. Toy vehicles. LINES, W., and LINES BROS., Ltd., Tri-ang Works, Morden Road, Merton, London. Oct. 21, 1932, No. 29419. [Class 132 (iii).] A brake for the road wheels of toy vehicles comprises a brake drum fixed relatively to the vehicle frame, a flexible friction drum contained within the brake drum and adapted to rotate with the road wheel axle, and one or more brake blocks loosely mounted on radial guides and also adapted to rotate with the road wheel axle, the arrangement being such that radial displacement of the blocks under centrifugal action will force the friction drum to engage with the brake drum. A metal brake drum a is riveted or otherwise secured to a fixed support, such as the frame-lug or bracket b supporting the road-wheel axle e. A flexible moulded rubber disc c with peripheral rubber flange c<1> and with central boss or hub c<2> is keyed coaxially to the road-wheel axle e by a pin or spindle d<1> carried by the axle e and passing through the boss c<2>. A brake-block d is slidably mounted on the spindle d<1> and moves outwards under the action of centrifugal force so that at excessive speeds it contacts with the flange c<1> and forces its outer surface into contact with the inner surface of the brake drum a to retard the speed of the road-wheel axle e. A second brake-block may be slidably mounted upon the spindle d<1> on the opposite side of the boss c<2> to the brake-block d.

Abstract: 1359004 Making sealed cell casings VARTA AG 23 June 1971 [26 June 1970] 29436/71 Heading H1B The base, side wall and cover of a cell container 1 consist of a single piece of metal or plastics shaped by forming an annular groove 12 in a cup-shaped blank, Fig. 2, and by deforming, e.g. rolling, pressing and/or upsetting the top part 11 to provide the cover, Fig. 3, Fig. 4 shows a nickel-cadmium storage cell during the process of forming the container 1 to provide a gas-tight enclosure. The electrode group 2 is spaced from the container bottom by an insulator 6. Before the top part 11 is closed (left-hand half of Fig. 4) a contact rivet 3 surrounded by a sealing and insulating ring 4 is placed above a synthetic resin post 5 provided in the cell. Thus, when the part 11 is closed (right-hand half of Fig. 4) the post 5 serves as an anvil on which the rivet 3 may be deformed to provide a contact cap and make a seal with the ring 4. The cell electrodes may be in the form of sintered coiled foils (Fig. 7, not shown). The contact cap 3 may include means to relieve excess gas pressure (Figs. 8-12, not shown). These means may be in the form of a rupturable membrane or in the form of a resilient stopper which recloses after relieving the pressure. In a modification (Fig. 6, not shown) the piece of metal or plastics is initially in the form of a tube open at both ends and both ends are deformed as shown for the cover in Fig. 4. In another modification relating to a primary cell (Fig. 5, not shown) the central post is formed by a carbon electrode.

The fuel may be controlled by means of a valve formed by the reduced end l of a threaded spindle m passing through the chamber b. The end l may be provided with radial or spiral slots. Valves may be provided for admitting steam or compressed air to the fuel passages to remove foreign matter. A thermometer may be inserted in a fitting at the side of the chamber b for indicating the oil temperature.

Title: Improvements in closing and sealing devices for cartons containing milk and the like
IPC: B65B7/08
Filed: 1934-10-15
Abstract: 431,106. Closing flexible receptacles. PHILLIPS, C. L. E. O. H. T., and PHILLIPS, E. B., Clanwilliam House, Walmer, Kent. Oct. 15, 1934, Nos. 29460, 31832, and 33392. [Class 94 (i)] Relates to the clos. ing of flexible milk and like containers by the application to the mouths thereof of a channel - shaped strip of metal. The strip is applied to the edges of the mouth of the container as shown at A, Fig. 2, and is subjected to the successive steps indicated at B, C and D by bending and pressure. A device for carrying out the steps comprises a frame 10 in which a die 12 is actuated to slide by a lever 15. The carton, with the metal strip thereon as shown at A is introduced into the frame at the left, a groove 14 acting as a stop and positioning device. The die is moved from the right into the position shown and forces the strip and carton top into the recess 13, imparting the form B, Fig. 2. The carton is removed, the resiliency of the material causing it to assume the form C, and is introduced between the dies 17, 18, the die 12 is moved to the right and imparts the flattened form D. The dies may be scored or otherwise formed to indent or mark the sealing strip. A modified form of device, Fig. 3, comprises pincer members 20 carrying jaws 22 25. One end of the jaw 22 carries a grooved die 23 and stop 24 to co-operate with a bevelled rib 26 on the jaw 25 and the other ends carry pressing plates 27, 28. In use, the steps B, C are effected by the parts 23, 26 and the final step by the pressing plates. In another form of apparatus, Fig. 7, a frame 30 carries a stationary die 36 mounted on bolts 34 to cooperate with a folding member 32 rotatable about an axis P. A movable die 43 having a bevelled edge 46 is mounted to pivot about a pin 44, being normally held in the position shown. In use, the carton and strip are inserted from beneath as far as a stop-member 49 will allow. The member 32 is rotated in the direction of the arrow Q. During its movement to the position shown in broken lines, the die 43 is held in position by the engagement of an arm 47 with the rear face of the member 32 and the folds B, C are effected. Continued rotation of the member 32 causes the arm 47 to be disengaged and the action of the forward edge on the surface 48 moves the die away to the left, while the strip is pressed flat against the die 36. The die 43 may be normally spring-held in the position shown, the arm 47 being omitted. The stop 49 may be mounted on the leading edge of the face 41 of the member 32. The arm 47 may be formed with a cam face to cause a slight initial counter-clockwise movement at the beginning of the operation, after having allowed more space for the introduction of the carton.
