Title: Improvements relating to the cooling of kiln-burnt granular or powdered materials
IPC: F27D17/00
Filed: 1957-08-07
Abstract: 843,708. Cooling discharged materials. SMIDTH & CO. A.S., F. L. Aug. 7, 1957 [Aug. 7, 1956], No. 24922/57. Class 51 (2). A method of cooling alumina, magnesia and cement &c. burnt in a kiln and issuing therefrom in a powdered state, consists in entraining the material in a stream of cool air, separating the material from the air stream, and leading all or the greater part of the air to the kiln for combustion purposes. As shown in Fig. 3, the burnt material passes into a hood 59 enclosing the lower end of a rotary kiln and thence into a hopper 60 discharging into a chamber 63 having porous lower walls through which air passes from chambers 64 connected to an air supply line 67. The material is carried by the air to a pipe 68 leading to a riser pipe 69 in which the material is entrained in a stream of air produced by a fan 71. The material is separated from the stream in a chamber 72 and falls into a pneumatic conveyer 74 and is discharged into a chamber 51 having partitions 53 and a cooling coil 58. The material is fluidized in the chamber 51 by air flowing through the upper porous wall 55 of an air supply chamber 54 and ultimately reaches the outlet 52. The air passes from the chamber 72 into a cyclone separator 76 from which separation material passes into the conveyer 74, while the air flows through a pipe 78 to the kiln burner tube 80. In a modified apparatus, the material from the kiln is distributed to a series of riser pipes and separators, discharging into chambers similar to the chamber 51 and arranged side-by-side.

Title: Improvements in or relating to homogenizers
IPC: A01J11/16
Filed: 1937-09-14
Abstract: 502,481. Valves. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and LOWE, R. G. Sept. 14, 1937, No. 24976. [Class 135] [Also in Group III] In emulsifying apparatus wherein the mixture to be treated is forced under high pressure between the surfaces of two valve members held in close proximity to each other, the valve members are located by tight contact between tapered peripheral surfaces other than the surfaces forming the homogenizing gap, one of the locating surfaces being that of a thin-walled funnel-shaped member. In the form shown, the lower valve member 16 is held in a flanged socket member 11 at the end of a cylindrical chamber 10 through which the fluid is forced. The upper end of member 16 is of taper formation, the upper boss portion 11b of the socket member 11 being correspondingly tapered, and having a thin-walled flared extension 11c within which is fixed the upper axially movable valve member 20. This member is loaded directly and positively by a compression rod 22, the loading of which is adjustable, e.g. by a differential screw. The fluid to be treated passes up the passage 25 in the lower valve member 16, is forced through the gap between the valve faces 17 and 21 and passes out through perforations in the member 11c, and outlet 15. The housing 11c is constructed to be in a state of circumferential tension, the degree of which can be adjusted by choice of the thickness and/or type of metal used. Specification 420,437, [Group III], is referred to.

Title: Improvements in or relating to apparatus for fastening stereotype plates to forme cylinders of rotary printing machines
IPC: B41F27/10
Filed: 1966-06-06
Abstract: 1,147,692. Plate-clamping device. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE A.G. 6 June, 1966 [5 June, 1965], No. 25060/66. Addition to 1,067,372. Heading B6C. Apparatus for fastening stereotype plates to forme cylinders wherein hooked latching members on the cylinder engage with corresponding grooves in the undersides of the plates is further provided with a quick-closing device which locks the plates to the cylinder while enabling a small degree of side register adjustment after locking. The apparatus is an improvement on the clamping device disclosed in Specification 1,067,372: the upper half of the drawing illustrates the quick-closing device and a non- sprung part of the latching members wherein the lower half illustrates the sprung portion of the latching members, both sets of features being included in any one fastening mechanism. When no plate 6 is present, latching member 13 is pressed into contact with cross-piece 16 carried on the cylinder 1 by spring 14, the stressing of the spring being adjustable by screw 15; a plate 6 is then placed on the cylinder with its two grooves overlying the latching members 11 13. An eccentric lock 5 operates a sliding bolt 4 of the quick-closing device and causes rotation of abutting thrust rod 9 which in turn locks the plate by forcing latching member 11 against the outside wall of the corresponding plate groove under the action of screw thread 12. At the same time, the plate is therefore drawn off crosspiece 16. Side register can be adjusted by rotating square section 10 which rotates thrust rod 9 without altering the position of the bolt 4.

Title: Improvements in and relating to the control of motor vehicle hydraulic drive systems
IPC: F16H61/40
Filed: 1960-07-20
Abstract: 894,464. Hydraulic transmission of power. PREROUSKE STROJIRNY NARODNI PODNIK-VYZKUMNY USTAV STAVEBNICH A KERAMICKYCH STROJU. July 20, 1960 [July 24, 1959], No. 25228/60. Class 69 (2). [Also in Group XXXI] A motor vehicle hydraulic driving system comprises a variable rate delivery pump 1 controlled by a spring-loaded member 5 driving a motor 2 through a valve 3 and direction-reversing member 4. The slide of valve 3 is connected by a rod 6 to a lever 7 rigid with a shaft 8. A pedal 10 is rigid with shaft 8 and a pedal 13 is connected with the shaft through links 11 and 12 so that depression of one pedal rotates the shaft in an opposite direction to that caused by depressing the other. The shaft 8 is also connected through a spring-loaded telescopic device 19, 15 and link 16 to a lever 17 provided with a ratchet or other locking mechanism 18. The lever 7 is pivoted to a rod 9, which, in the initial position of lever 17, is a distance M from the member 5. In this position the motor has a low delivery rate and the valve 3 is in the position whereby the flow is returned to reservoir. Upon moving the lever 17 in the direction of the arrow S, the valve 3 is progressively opened and the output of the motor increased by depressing the member 5. The lever 17 may be fixed in any desired position by the ratchet mechanism 4 and momentary braking or accelerating conditions may be obtained by operating one or other of levers 10 and 13 against the pressure in one direction or the other of spring 19. In a modification, Fig. 2, the shaft 28 is connected by a link 27 to a rod 29, 26 through which the spring- loaded motor control member 25 and valve 23 are operated. The shaft 28 is biased to move in a direction to open the valve 23 and increase the pump delivery rate by a spring 39 connected to a link 34 integral with the shaft. A rope 35 or rod provided with a lost-motion connection is connected between the link 34 and a link 36 connected to operating-handle 37. By moving the handle in the direction of arrow P the speed of the vehicle is increased to a set of operating conditions which are maintained constant by setting the handle with the ratchet or other locking mechanism 38. A momentary braking force may be applied by depressing the pedal 33, the anticlockwise motion produced being unhampered by the rope 35 or lost-motion rod. In modifications to either embodiment, the pump 21 may have a position for zero output or may be of the reversible type with consequent omission of the valves 3 and/or 4, and 23 and/or 24. Alternative forms of operating levers are also referred to.

Filed: 1958-08-07
Abstract: 887,978. Producing composite photographs. SHUFTAN, E. J. Aug. 7, 1958 [Aug. 9, 1957; April 21, 1958], No. 25376/58. Class 98(2). Apparatus consisting of a camera 1, apertured mirror 5, optical or kinematograph projectors 2, 10, 11, 12 and 13, back-projection screen 6 and collimator lens 7 arranged so that when camera 1 is focused on screen 8 screen 6 will also be in focus, the mirror 5 lies between wide limits of its distance from the camera defined in terms of the size of the circle of confusion formed on the camera focusing screen by a point on the mirror. The optical or kinematograph projectors form the same images on screens 6 and 8 and the aperture in mirror 5 restricts the amount of screen 8 which can be photographed by camera 1. Accordingly, the actors 9 are surrounded by dead ground in which scene shifting can take place. The aperture is of irregular outline and the mirror can be moved lengthwise in order to make it less conspicuous. Alternatively, the aperture may be bounded by a semi-reflecting marginal band. The member 3 may be a camera or a lamp which projects an outline of the aperture in mirror 5 on to screen 8. In order to maintain the same relative sizes of the images on screens 6 and 8 as platform 23 moves towards and away' from screen 8, wheels 24 are geared to threaded spindle 28 which moves projector 2 by means of nut 29. A cam arrangement is included between the wheels and spindle. Different ways of using several projectors to obtain even oblique illumination of a screen and undistorted back or front projected images and a form of mask 21 for rendering the overlap between projected images inconspicuous are described.

Abstract: 608,127. Adhesive sheets. JOHNSON & JOHNSON (GT. BRITAIN), Ltd. Dec. 18, 1944, No. 25411. Convention date, Dec. 17, 1943. [Class 140] An adhesive sheet has a flexible backing presenting smooth non-fibrous surfaces, a normally tacky polyvinyl acetal or polyvinyl ether adhesive directly united to the backing on one surface thereof and a flexible film of a cellulose ether or ester united to the opposite surface whereby when a plurality of layers of the adhesive sheets are arranged in close superposed relation the film serves as a repellent eliminating the risk of permanent joinder of the adhesive of one layer to the backing of the adjacent layer. As backings regenerated cellulose and rubber derivatives are indicated and to these polyvinyl adhesives as disclosed in Specification 585,481; or polyvinyl ether adhesives comprising polyvinyl ethers, tackifiers and commercial rubber anti-oxidants may be applied by solvent or hot melt spreading. The repellent film is applied to the backing by similar methods, or by attachment of a preformed layer of repellent to the backing by means of heat, either before or after the adhesive is applied to the opposite surface of the backing. As repellents nitrocellulose, methyl cellulose and cellulose acetate have proved very satisfactory. Nitrocellulose used on a backing of regenerated cellulose may havea plasticizer such as a modified glycerolphthalic anhydride resin and a trace of wax included in it. The adhesive-repellents may be anchored to backing material by an agglutinant such as polyvinyl alcohol, casein and glue. The Specification as open to inspection under Sect. 91 indicates also the use of adhesives containing rubber, synthetic rubber, vinyl polymers, butadiene-vinyl copolymers, polyvinyl esters, alkyd type adhesives and glue; and adhesive-repellent films or coats made from acrylic polymers such as methyl methacrylate or methyl acrylate and butadiene copolymers, preferably the commercial dispersions of copolymers of butadiene and styrene, or acrylonitriles. This subject-matter does not appear in the Specification as accepted.
