Title: Method of and apparatus for monitoring tobacco manipulating machines
IPC: A24C5/32
Filed: 1971-04-19
Abstract: 1352942 Cigarette and tobacco-smoke filter making-machines HAUNI-WERKE KORBER & CO KG 19 April 1971 [2 April 1970] 23038/71 Heading A2C [Also in Divisions B8 Gl and G3] To monitor the efficiency of a tobacco handling machine, measurement signals representing the weight of tobacco or other material supplied to the machine and the weight of tobacco or product leaving the machine at at least one point are processed to indicate the or each ouput as a fraction of the input. A cigarettes rod machine and a filter attachment machine as described in Specification 1352941 (Figs. 2-4, not shown) are provided with weighers and counters so that the wastage of tobacco dust, tobacco rib and foreign bodies, unusable cigarette rod parts, faulty plain cigarettes, faulty tipped cigarettes may be compared with the weight of tobacco supplied. In the filter producing machine KF shown; tow from a bale 306 passes air nozzles 307, 308 to loosen the fibre, is moistened in a spray deivce 312, gathered into a rod at 323 and fed on to a wrapper strip 327 which is wrapped round the rod in a former 329, the seam being flattened at 332. A cutter 333 severs filters from the filter rod 331, these passing to a delivery drum 337. The bale 306 is supported on a weigher MK2, a difference unit 346 subtracting the instantaneous weight signal from an initial weight signal from a store SpK2 to provide a signal representing the weight of tow drawn into the machine. Counters MK11, MK12 count rejected filter rods and sound filters respectively. Recorders AK11, AK12 indicate wastage and usable output as fractions of input. A recorder 352 indicates the amount of material per filter. A signal corresponding to this indication goes to a comparator 353 having an input b corresponding to the ratio of a variable-speed gear 316 in the drive to rollers 303, the comparator output acting via an amplifier 357 to adjust the gear ratio to maintain the amount of material per filter within desired limits.

Abstract: 1,021,373. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. June 12, 1963 [June 15, 1962], No. 23210/62. Heading B7K. An air cushion vehicle has its supporting cushion contained for at least part of its periphery by a hollow, inflatable wall structure comprising two spaced-apart walls and constraining means connecting said walls, at least a part of said structure being extensible so that it extends when subjected to increase in inflation pressure, means for supplying to inflate the structure and means for controlling and varying the inflation pressure whereby the shape of the structure is varied by extension of said part. A nozzle for forming the fluid curtain comprises inflatable structures 1 and 2 having inner walls 3 and 4 and outer walls 5 and 6 respectively connected at their upper ends to recuperation spaces 7 and 8 to which air is supplied by a pipe 9, air for forming the curtain being supplied via a duct 10. The inner and outer walls are connected by ties 12 and the walls and/or the ties may be constructed of materials having differing degrees of elasticity whereby increase of inflation pressure will cause the structures 1 and 2 to take positions such as those indicated by dotted lines. The invention is described also for use in sidewalls and stability keels and apparatus is described for varying the inflation pressure. Instead of the constraint between the walls of a structure being by cords, the walls can be constrained by the space between them being filled by a foamed rubber or plastic.

Abstract: 598,661. Treating cereals. PORTEUS, W. Nov. 24, 1944, No. 23410. [Class 58] [Also in Group II] In a grinder and delivery system for cereals in which the bulk of the ground material passes directly to a delivery hopper I beneath the grinder A, high-velocity air is drawn across the bottom of the grinder by means of a fan C blowing the dust-laden air drawn from the grinder through a tube M into a cyclone F from which a proportion of the air is returned through a tube E to be repassed across the bottom of the grinder to and by the fan. The fine meal blown to the cyclone is delivered by a conduit L to the delivery hopper I. Humid air not returned to the grinder passes to atmosphere through canvas sleeve filters P on a saddle-backed cowl O, Fig. 2 (not shown).

Title: An improved steering gear for motor driven vehicles
IPC: B62D6/02
Filed: 1954-08-12
Abstract: 768,264. Vehicle power steering. SOC. ANON. A. CITROEN. Aug. 12, 1954 [Dec. 3, 1953], No. 23415/54. Class 79(5). Two of the transmission elements in the steering mechanism of a motor-driven vehicle are coupled together by an elastic or flexible sleeve so that, when a predetermined resistance to the steering movement is encountered, the sleeve yields rotatively to allow relative movement between the transmission elements, and such movement operates a valve controlling a power-assisting servomotor. Direct manual actuation takes place through a rotary shaft 7, a rubber sleeve 8, and a rotary sleeve 6<SP>1</SP> which carries a pinion 6 meshing with a rack 5 connected to the steerable wheels. The sleeve 6<SP>1</SP> and shaft 7 are provided with opposed and relatively inclined slots 9, 10, respectively, and a transverse pin 11 connected to the control valve 14 of the servomotor passes through the slots. When the resistance to a direct manual steering actuation exceeds a predetermined amount, sleeve 8 allows shaft 7 to twist relatively to sleeve 6 so that the pin 11 slides longitudinally in the slots and the resultant actuation of the valve energizes the piston-and-cylinder servomotor to move the rack 5. A separate valve is provided which, when actuated, cuts off the servomotor from control by the valve 14 and also interconnects the two ends of the servomotor.

The front spacing bolt 22 engages a slot 31 in the timer plate 30 to prevent rotation of the timer. The rear bolts 24, 25 are in two parts hinged together by pins 41 and, after releasing the front bolts, the two chassis plates can be swung apart, the gear 36 on one side passing through an opening 40 which, to simplify interchangeability, is provided on both chassis plates. The meter mechanisms are described in Specification 751,075.

Convention date, Aug. 28, 1930. [Class 4.] For regulating an aircraft internal combustion engine in accordance with the variations of atmospheric pressure at different altitudes, or for other purposes, the engine control is connected to a piston in a pneumatic cylinder 4 supplied at one end 4b with air at constant pressure produced by a primary air compressor 1 provided with a reducing valve 8 or equivalent means and at the other end 4a with air from a secondary compressor 2 having a compression volumetric ratio responsive to the position of the piston 5 of the pneumatic cylinder. The supercharger valve or other control is connected to the piston-rod 6 of the piston 5 which also moves a lever 15 pivoted at 14 and connected by a link 13 to a piston 12 in an auxiliary compression space 11 in the compressor 2. As the atmospheric pressure diminishes the piston 5 moves to the left moving with it the piston 12 which lessens the compression volumetric ratio of the compressor 2 and increases the output pressure until the piston 5 reaches a stable position. The compressors 1, 2 are driven from a common shaft 3. The constant pressure in the end 4b of the cylinder may alternatively be derived from an oil pump. According to the Specification as open to inspection under Sect. 91 (3) (a) the source of constant pressure may be a spring or the supply pump of a Diesel engine.
