Title: Improvements in and relating to the manufacture of portland cement, lime and the like
Inventor: DAVIS GEOFFREY GEORGE JOHN
IPC: F27B7/20
Filed: 1956-05-16
Abstract: 828,888. Drying systems. ASSOCIATED PORTLAND CEMENT MANUFACTURERS Ltd. May 9, 1957 [May 16, 1956], No. 15315/56. Class 34(2) [Also in Group XII] Apparatus for drying and preheating granular materials such as cement raw materials, lime and ores, comprises an an nular rotary hearth 1, surmounted by a rotary bowl 2 and a fixed dome structure 22 forming therebetween an annular passage 24, and a stationary roof 3 carrying a flue 4 equipped with a fan F and a charging hopper D. Raw material fed from the hopper D by a rotary pocketed drum E is distributed over the dome 22, and traverses the passage 24 on to the hearth in countercurrent to hot gases which leave the kiln K by a shaft S and are exhausted by the fan F. The hearth rotates about an axis x-x and the bowl about an offset axis y-y. resulting in material being discharged from the hearth into the shaft S at a rate depending on the offset distance and the speed of rotation. Discharge of material from the hearth is assisted by the provision of a step 41 which may be sloped. steeply or gradually or may be dished, Figs. 4-6 (not shown). A ring 8 on the hearth rests on support rollers 9 carried by a sub-frame 27 adjustably mounted on a platform 7 carried by a framework 6, said ring being also engaged by thrust rollers 10. The sub-frame 27 may be moved by jacks 28 to vary the axis x-x. The hearth is driven by a motor N through reduction gearing and a pinion 33 engaging a driving ring 34, and, normally, frictional drag between the hearth, the bowl and the charge results in the two parts rotating together. Alternatively, the hearth and the bowl are connected by pivoted or flexible links, or are driven separately at the same speed. The bowl has a ring 13 engaged by support rollers 15 and 16 and by thrust rollers 20, all the rollers being mounted on a superstructure 18 disposed on the platform 7. The rollers may be adjusted vertically in their supports, Fig. 8 (not shown) to raise or lower the bowl. Waterseals 30 and 31 are respectively disposed between the hearth and the shaft, and between the bowl and the roof, and an air seal at 35 may be replaced by flange plates enclosing an asbestos gland. Fig. 8 (not shown). In a modification, Fig. 3 (not shown), the bowl is cylindrical in shape and the dome structure 22 is suspended on a shaft mounted in bearings on a cross-bar of the superstructure 18. Specification 828,886 is referred to.

Filed: 1937-06-03
Abstract: 496,729. Feeding cigarettes. BEST, C., and MOLINS MACHINE CO., Ltd. June 3, 1937, No. 15416. [Class 117] [Also in Group VI] A device for compressing the tobacco at the ends of cigarettes and for rejecting defective cigarettes comprises a pair of presser elements yieldingly mounted to move inwardly towards each other, means to deliver cigarettes one at a time between the presser elements, and means to arrest the inward movement of the presser elements after they have moved a predetermined distance. The presser elements may be heated to facilitate their compressing action, for example by contact with a heating surface at some point during their rotation. Cigarettes in a hopper 6 are agitated by a plate 9 actuated from a cam 13 and are fed one at a time into flutes 7 in a rotatable carrier 8 ; or the flutes 7 may receive cigarettes delivered directly from a continuous-rod machine. The cigarettes pass beneath a spring steel band 16 similar to that described in Specification 496,413, [Group VI]. The ends of each cigarette are engaged by presser elements 19 carried by arms 20 pivoted at 21 on the carrier 8 and connected by a spring 22, so that tail pieces 24 engage stationary cams 23. An adjustable stop 25 on each arm 20 engages the side face of the carrier 8 to limit the inward movement of the presser. In order to test the cigarettes for ends that are too soft, feelers 26 slidable in the presser elements 19 pass between thin spring plates 27. Normally the feelers engage a plate 48 and cause a pivoted carrier 43 to break the circuit of a solenoid 33 ; on the passage of a soft-ended cigarette, the feeler will not turn the carrier 43 and the solenoid actuates an arm 34 to interpose projections 29 on a plate 28 into the path of the cigarette, which is diverted and rolls down a plate 57. The projections 29 are retained in position by a D-shaped element 51 until the defective cigarette has been delivered. Normal cigarettes are retained in the flutes by a shield 5 until a discharge point is reached. Specification 386,417 also is referred to.

Patent GB-639146-A (GB)
Title: Improvements in or relating to hydraulic power lift systems for tractors or the like
IPC: B62D49/02
Filed: 1947-06-17
Abstract: 639,146. Agricultural implements. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd. June 17, 1947, No. 15922. Convention date, Sept. 21, 1942. [Class 6 (i)] [Also in Group XXIX] In a hydraulically operated power lift for a tractor the limit of movement of the power lift in one direction is determined by a fluid-pressure-operated adjustable stop means. The tractor is fitted with four hydraulic cylinders the two cylinders on one side of the tractor working independently of those on the other side, the operation of the two cylinders on one side being herein described. Oil is pumped to a chamber 44<SP>1</SP> from which the oil is normally exhausted through an orifice 74. A hand-lever engages a lever mounted on a shaft 51 on which is secured a lever 50 forked at one end to engage a sleeve 48. This sleeve has two slots 78 and 79 which co-operate with a passage 80 leading to an auxiliary cylinder 100 mounted at the end of the front cylinder 28. The stop piston 101 of this cylinder 100 has a rod 102 projecting into the front cylinder. The other end of-lever 50 engages a latch 56 which engages at one end a plunger 58 and at the other end a cup 59 covering a spring-urged ball valve 62. The shaft 51 is spring-urged to move lever 50 to a neutral position where the sleeve 48 is situated so that passage 80 lies midway between the slots 78 and 79. To raise the implements the hand-lever is operated to move the lever 50 so that the sleeve 48 closes orifice 74 in which position the lever 50 will be engaged by latch 56. Pressure builds up in the chamber 441 and opens ball valves 85, 86 to allow oil to flow into the front and rear cylinders. When the pistons reach the end of their stroke sufficient pressure will build up to unseat the ball valve 62 and raise cap 59 releasing the latch 56 and allowing the lever 50 to return to its neutral position. To lower the implements-the lever 50 is moved so that a member 94 pivoted thereon first contacts a push pin 96 and then a pin 961, which opens valves 85, 86 in succession. To adjust the depth of the front implements the lever 50 is moved to bring the slot 78 in sleeve 48 into alignment with the passage 80 in which position orifice 74 is closed causing the implements to be raised, oil also flowing into cylinder 100 to move the stop piston 101 in step with the main piston, the latch 56 being unhooked. On release of the hand-lever it will be returned to neutral by the spring on shaft 51, closing the passage 80 and retaining the stop piston in its new position. A similar operation adjusts the main piston and stop piston in the opposite direction. The mechanism for each set of pistons is operated either singly or jointly by the hand-lever. The depth of the rear tools may be adjusted by a hand-lever, connected to the rear piston rod, which co-operates with a sector connected to the lifting arm of the rear tools.
