Abstract: 866,900. Linkwork. ROLLS-ROYCE Ltd. Oct. 11, 1957 [Oct, 16, 1956], No. 31530/56. Class 80 (3). An axially-loaded partlyrotatable member, such as a ring 22 forming part of a jetreversing structure in a jetpropulsion nozzle, is given a limited displacement at rightangles to the load, i.e. circumferentially, by means of one or more motors or rams 27 acting through one or more of a number of load-sustaining straight-line linkages arranged around the periphery of the member, each linkage comprising a pair of levers 12, 13 pivoted at 14, 15 to a fixed casing 21 and pivoted at 17, 18 to a link 16 pivoted at 19 to the ring 22. The pivots 14, 15 are spaced circumferentially so that over a short range of movement the pivot 19 moves in an approximate straight tangential line. The levers 12, 13 carry rollers 30 running between radially-spaced members fixed tangentially to the casing 21 to prevent bending of the levers. The pivots 17, 18, 19 may include spherical-faced elements to accommodate changes of alignment. As shown, the ram 27 is linked to the lever 13 through a bell-crank. Specification 811,455 is referred to.

Abstract: A colloidal organic solution is obtained by extracting with water at temperature not greater than 75 DEG C. seaweed of the Euchema genus preferably after an external rinsing and thorough crushing. The extraction may be carried out in stages, firstly using water at a temperature of below 40 DEG C., preferably 30 DEG C., and secondly extracting again with water at a temperature of 40 DEG -75 DEG C. The residual seaweed may again be extracted at a temperature of 100 DEG C. or higher.  The water used for extraction may be acidified or alkalinised and the extract or extracts preferably neutralised. The preferred seaweed in Euchema muricatum and it may be immersed in a salt solution and freed from adherent salt before the extraction takes place.  The resulting solution may be dried on cylinders or dewatered by means of alcohol and then milled to a powder.  The extract in liquid or solid form may be added to ice cream, fruit ices, cocoa mixtures and sherbert, and the product obtained by extracting the seaweed residue after extraction up to 75 DEG C. at a temperature up to 100 DEG C. may be used in the canning of meat and fish and in the manufacture of custards and jellies.ALSO:A colloidal organic solution obtained by extracting seaweed of the Euchema genus with water at a temperature not greater than 75 DEG  C., preferably after an external rinsing and crushing, is used in foods and medicine.  The water used for extraction may be acidified or alkanized and the extract or extracts subsequently neutralized.  The preferred seaweed is Euchema muricatum and it may be immersed in a salt solution and freed from adherent salt before the extraction takes place.  The resultant solution may be dried on cylinders or dewatered by means of alcohol and then milled to a powder.  The extract obtained by treatment at about 40 DEG  C. may be added to ice cream or fruit ices and that obtained by extracting below 75 DEG  C., e.g. at 50 DEG  C. may be added to sherbert and cocoa drinks.  The product obtained by re-extracting the weed at a temperature up to 100 DEG  C., after it has been extracted below 75 DEG  C., may be used in the canning of meat and fish, and in the stabilization of custard and jellies, and in the dried form it may be used as a mechanical laxative particularly in tablet form.

Filed: 1928-11-05
Abstract: 322,304. Causebrook, W. C. Nov. 5, 1928. Obstruction removers and safety appliances.- In a vehicle life-guard of the kind in which one or more flexible strips or aprons are connected to a number of rods and adapted to be extended to an operative position to serve as a catching- device, the rods 10 carrying the flexible material 11 are mounted at their inner ends on substantially vertical pivots 14 on collars 15 which are arranged to hinge about a common spindle 16, the latter being associated with a sliding piston 12 which, when moved outwardly in its cylinder 13, causes the rods 10 first to open out fanwise about the pivots 14 and then to drop into contact with the road by turning about the spindle 16. In the construction shown two catching devices are employed supported, one at each side of the vehicle, by brackets 45, Fig. 5, but a single centrally disposed device may The used. Each of the outer rods 10 is connected by a hinged link 18 forming a toggle joint to an operating rod 21 which moves outwardly with the piston 12 until an abutment 22 on the rod strikes a stop 23 at the front of the cylinder 13, following which further movement of the piston acts through the links 18 to spread the rods 10. Movement of the piston 12 is effected by the explosion of a cartridge 30 which is fired by a spring-pressed contact 33 released by the driver through the medium of a lever 39. Near the end of the piston's stroke, the pressure in the cylinder 13 is released by a flap valve 47 on the piston being opened by contact with an extension 29 of the abutment 22. A screen 42, Fig. 5, of netting, canvas or similar material may be disposed above the brackets 45, being carried on supports 43 which are normally disposed in an horizontal position, but are erected either by hand. or automatically to a vertical operative position.

Title: Improvements connected with coal breaking and screening apparatus
IPC: B02C1/12
Filed: 1927-12-01
Abstract: 290,920. Rees & Kirby, Ltd., and Norton, H. Dec. 1, 1927. Reciprocating picks.-In apparatus for breaking and screening coal, a breaker ram 6 is operated in conjunction with and disposed above a conveyer screen deck 3 so as to break or crush the coal between the ram and screen deck. The screen 3 is suspended by swinging arms 4 from cross shafts 5 which obtain a partial rotating movement when the screen 3 is reciprocated by means of a connecting rod 9 connected to the lower end of one of the swinging arms 4. To one or several of the shafts 5 is rigidly attached a breaker ram which may consist of two inverted L-frames 6 connected by a cross-member 7 with teeth 8; the cross member 7 may be variable with relation to the end frames 6. By the rocking action of the shaft 5, the breaker ram rises and falls so that on the return movement of the screen 3, the breaker ram is brought into contact with the coal, whilst on the forward movement of the screen the breaker ram is raised and allows the passage of the broken coal. Further meshes in the same screen complete the classification of the broken coal. Screens other than reciprocating may be used.

[Class 58.] Cereals from a silo S pass through a magnetic separator and sorter R and then into a washing and wetting machine I where they are treated in a drum revolving in water for a sufficient period for the husks to become loosened and softened, dirt, sand and dust being washed away. Thence the grain passes to a huskloosening machine II in which it travels from the top to the bottom under the action of gravity, slowly rotating stirring arms f being provided to facilitate its passage to the outflow c: the stirrers also carry brushes i to remove grain sticking to the sides or the bottom of the drum. The separate grains rubbing against each other under the action of gravity strip off their husks. The grain and the husks pass into a washing- machine III and from this the grain flows to a dryer IV. If necessary the grain may be passed through a second husking machine V and a brushing-machine VI.

The cigarettes are fed to the belts 3, 4 by belts 1, 2. The belts 3, 4, are carried by a frame 12 which is pivotally mounted at 11 and balanced by a counterweight 15. The frame at the downstream end of the belts 3, 4, is formed with a guide plate 25 for feeding the cigarettes on to the top of cigarettes on a further conveyor belt 24. A bearing member 26, rigid with the plate 25, rests on the cigarettes on the conveyor 24. As the level of the latter builds up, the frame 12 is raised by being tilted about the pivot 11. The difference in speeds of the belts 3, 4, is obtained by having respective individual drive rollers 9 of different diameters. The cigarettes may be maintained on the belts 3, 4, by means of a cover belt 17. As shown, the frame 12 carries a second set of conveyor belts 3', 4'.
