Abstract: 698,194. Gasifying particulate carbonaceous material. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 2, 1952 [Jan. 18, 1951], No. 1389/51. Class 55(i) A process for making gas from finely divided carbonaceous material such as coal comprises passing a stream of fluidizing and endothermically reacting gas upwardly through a bed of the material in a gasification zone whilst supplying heat to the zone by transferring part of the material to a closed combustion zone wherein it is partially burnt by a fluidizing stream of air and recirculating the heated char to the gasification zone, the combustion zone being arranged in heat exchange contact with the gasification zone. In one form, the apparatus consists of a cylindrical gasification chamber 1 within which is mounted a combustion chamber 11. The bed of coal &c., to be gasified rests on a grid 2 and is fluidized and gasified by superheated steam admitted at 4. Fresh coal is fed through a pipe 5 to keep the bed at a level 3, the gases produced discharging through a pipe 6. Coke is withdrawn at 10 and transferred into chamber 11, passing upwardly through the chamber in a stream of air entering at 13. Part of the coke is burnt to heat the remainder which is separated from the combustion gas in a cyclone 15 to be returned to the gasification zone through pipe 16. Heat losses through the walls of the combustion chamber are thus prevented. The process may also be applied to the carbonization of coal, &c.

Abstract: 295,545. Glover, M. L. Jan. 17, 1928. Macadamized roads; foundations.-A concrete mass for road or floor surfaces comprises an upper layer consisting of aggregate of various sizes and cement proportioned to form interstices which are filled partly with stone chippings, gravel, or sand, and partly with bitumen, tar, or the like, applied as an emulsion, and a lower layer of dense concrete some of the aggregate of which interlocks with the aggregate of the top layer. In an example, the upper layer of a concrete road comprises 20 parts of broken stone of sizes from 1¢ inches to # of an inch, 3 parts of sand, 1¢ parts of cement and sufficient water; this is laid on a bed of unset dense concrete and is compressed by rolling until the air spaces are 20 per cent of the volume of the top layer; fine chippings, &c. are then brushed into the interstices and emulsified tar or bitumen is applied by spraying or grouting to fill the interstices and form a surface layer. In a modification, the amount of cement mixed with the aggregate is such that the greater part of the cement settles to form a dense lower layer, the upper layer having interstices, which are filled with chippings and bituminous material. This is illustrated in Fig. 1, in which the lower layer e comprises stone a, and cement mortar b only, and interstices filled with chippings and bituminous material c. Before applying the chippings and bitumen, sand may be brushed into the interstices to form a layer free from bitumen or tar.

Title: Apparatus for continuously producing ice cream and other plastic substances
IPC: A23G9/20
Filed: 1929-01-18
Abstract: 330,886. Vogt, C. W., and Vogt Instant Freezers, Inc. Jan. 18, 1929. Butter substitutes. - In apparatus for the continuous production of icecream, margarine, &c., by the use of a cooling or heating medium and in which the supply of the medium is varied according to the plasticity and the consequent resistance to movement of the material, the material is agitated at every part of its path while, subjected to the action of the medium. In an apparatus for freezing cream, the cream flows from an inverted bottle 20 into a reservoir 21 and thence through an opening controlled by a handregulated ball-valve 22 into a passage 25 in the wall of a cylinder 26 containing a plunger 27 which forces the cream, together with incorporated air, into a brine-jacketed freezing-cylinder 37. The cylinder contains a shaft 16 carrying stirrers 41 which agitate and remove the cream from the inner wall of the cylinder and communicates through an opening 43 in a whipping chamberat the upper end of the cylinder with a flexible tube 143 through which the cream is fed into the vessel 12. The shaft 16 is driven through a spur gear 51, Fig. 5, and a pinion 50 from an electric motor 14. The pinion is connected through a slidable coupling 63, 64, Fig. 8, with the motor shaft and secured to a stub shaft 52 adapted to slide in a sleeve 53 secured to a shaft .55 connected by a pivoted lever 68 to the rod 69 of a piston valve which controls the flow of cold brine from a supply pipe 79 to pipes 73, 75 connected respectively to the jacket of the freezing-cylinder and the outlet pipe 49 from the jacket. When the cream becomes unduly hard, the resistance offered by it to the stirrers causes the coupling parts 63, 64 to separate and the pinion moves the rod 55 to the right against the resistance of the spring 61 and through the lever 68 diverts the supply of brine from the jacket supply pipe 73 to the discharge pipe 75. If the cream becomes unduly soft, the mechanism operates to increase the supply of brine to the jacket. The plunger 27 which feeds the cream into the freezing-cylinder is formed with a central passage 34 which communicates through spring. loaded ball valves 33, 36 with the air compression chamber 32 at the end of the cylinder 26 and the cream passage 25 in the cylinder wall. During the upstroke of the plunger, which is effected by a cam 29 on the shaft 16, compressed air and cream pass into the central passage of the plunger, and during the downstroke, which is effected by a spring 26a, the air and cream are forced into the freezing-cylinder. Specification 330,887 is referred to.

Abstract: 824,933. Record changers. STAAR, M. J. H. Jan. 20, 1956 [Sept. 17, 1955], No.1983/56. Class 40 (2). In a record-changing gramophone or recordplayer including a stem 2 provided with a pivoted lever 9 the upper end of which is initially located above the level of an abutment 4 on the stem which supports a stack of records D 2  . . . D 6  so that pivotal movement of the lever causes the upper end thereof to engage the centre hole of the lowest record of the stack and shift that record laterally to clear the abutment, the lever extends beyond the lower end of the stem and is movable vertically under the weight of the remaining records of the stack to a position in which the upper end of the lever is at the same level as the abutment, and there is return spring means 13 co-operating with the lower end of the lever to cause return pivotal movement of the lever clear of the lowest remaining record of the stack after a recordchanging operation and then to return the lever upwardly to the initial position thereof when the remaining records of the stack are supported by the abutment. As shown, the lever 9, which has a longitudinal slot 12 and is pivoted on a pin 10 carried by the stem 2, is rocked about the pin by movement of an element 11 which during a record-changing operation is moved in the direction of arrow F, Fig. 2, to swing the lever about the pin and cause the record D 2  to be shifted laterally clear of the abutment and allow that record to slide down the stem and on to the turn-table of the apparatus; the remaining records D 3  ... D 6  descend while the upper end of the lever 9 is engaged with the lower surface of the record D 3 , the lever consequently moving down within the stem 2 to the position shown in Fig. 3, whereby the end of the lever is level with the abutment which takes the weight of the records. Movement of the element 11 away from the lever frees the lever for return pivotal movement clear of the record D 3 , this movement being effected by a ramped end portion 13<SP>1</SP> of the spring which causes a pivoting force on the lever acting in the direction of the arrow F 1 . On completion of this movement the spring moves the lever upwardly to the position shown in Fig. 1, ready for the next record-changing operation.
