Title: An instrument for the testing for accuracy of weighbridges and other weighing instruments of high capacity
IPC: G01G23/01
Filed: 1949-11-30
Abstract: 695,362. Testing weighing apparatus. BURTON, P. Nov. 29, 1950 [Nov. 30, 1949]. No. 30714/49. Class 143. An instrument for testing the accuracy of weighing instruments of high capacity, e.g., weighbridges, comprises a fulcrummed lever, one end of which is coupled, during testing, to the long arm of a steelyard under test or, if a self indicating scale is under test, to a subsidiary lever thereof, and a weight carrier which is supported by said lever between said one end and the lever fulcrum; and is characterized in that the carrier is movable along the lever so that the movement of a unit weight supported thereby can be adjusted to balance a heavier unit weight supported by the weighing instrument whereafter, when additional unit weights are placed on the carrier, the movements of the load counterbalancing means of the weighing instrument necessary to return the weighing instrument to equilibrium should correspond with unit increments of load indicated by said weighing instrument. The instrument shown in the Figure operates as follows: With the lever A coupled to the long arm of a steelyard M by link O, carrier I in its extreme position of adjustment on the left hand end of the lever and a detachable weight G exactly counterbalancing said carrier, a heavy load, e.g. a lorry, is moved onto the weighbridge and the steelyard counterpoise is adjusted to return the system to equilibrium. Since the lever is itself in equilibrium it plays no part in counterbalancing the load. The detachable weight G is now removed, an additional load of one ton is applied to the weighbridge and the carrier I is moved by a screw K to a new position on the lever in which it again restores equilibrium in the system, thus the additional load is exactly counterbalanced by the carrier assembly and subsequent, incremental additions of weights-each of the same weight as the carrier assembly-can then be counterbalanced by incremental subtractions, in one ton steps, of the counterbalancing force exerted by the steelyard counterpoise to check its accuracy. In a modification described in the Provisional Specification only the detachable weight G is replaced by a weight equal to the carrier assembly and mounted on a reverse threaded screwed extension of screw K so that the carrier is counterbalanced in all positions of adjustment. With this arrangement assuming the parts to be in equilibrium with the heavy load on the weighbridge, a one ton weight is applied to the weighbridge, a one unit weight is applied to the carrier and the system is again brought into equilibrium by movement of the carrier; the testing operation is then carried out as before. The use of both these instruments is also described in connection with the testing of self indicating scales.

Filed: 1930-10-18
Abstract: 365,184. Appliances actuating on breakage of web in paper-machines. BOWATER'S PAPER MILLS, Ltd., Northfleet, and LINGGOOD, W. J., 156, Upper Wrotham Road, both in Gravesend, Kent. Oct. 18, 1930, No. 31321. [Class 96.] One or more light-sensitive devices such as photo-electric cells are used for detecting breaks in a paper web, light passing to a cell being modified, by fracture of the web at the corresponding part of the machine, to render operative means for shifting a cross-cutter fluid jet, which impinges upon the paper web before the latter leaves the wire, temporarily to determine the width of the web passing from the wire to the subsequent sections of the machine. Photo-electric cells &c. with relays 22, 23, 33, 34, 35, having windings 66, 70, &c., and the usual thermionic valve amplifiers are provided for the press section and for the first and second drying sections of a paper-making machine &c., the contacts 69, 70, &c., being to the right during normal running. On rupture of the web at any position, the corresponding cell relay contact moves to the left and connects the positive lead 64 to a crosscutter relay coil 78 ; contacts 84, 80, 85, 89, 88, &c., being normally closed and a contact 76 being normally open. The coil 78 being thus energized closes the contact 76 which is connected by leads 77 to the cross-cutter motor thereby cutting the paper immediately in front of the couch roll preferably to reduce the width of the web to allow it easily to be handled. After a slight lag the contact 84 is opened thereby disconnecting the coil 83 of a resetting relay.79 thus opening contacts 80, 85. Opening the contact 80 disconnects the coil 78 of the cross-cutter relay and also the coils 87 &c. of the other resetting relays. The contacts 76, 84 therefore return to the normal position shown thus stopping the cross-cutter motor; the resetting relays however remain disconnected owing to the contacts 85, 88, &c., being open as are also the cell relay contacts with which they are in parallel. Normal operation being resumed only when all the photo-cells are darkened. Two light beams may be directed on the web one near each edge and both directed to a single cell unit in the region where a break is most likely to occur. The movable jet may be controlled by hand &c. or by electric switches &c. particularly for re-establishing the paper web to full width. The doctors &c. may be moved by the relay mechanism. According to the Provisional Specification a break may also be indicated by audible and visible means.

Title: Improvements in or relating to steaming and drying machines
IPC: D06F73/02
Filed: 1929-10-16
Abstract: <PICT:0342252/IV/1> <PICT:0342252/IV/2> A power-driven machine for steaming and drying garments &c. comprises a plurality of garment holding members carried by a rotatable support which is geared to turn at predetermined intervals through part of a revolution to carry a holding member from a garment applying and removing station to a steaming chamber and then after a further interval to a drying station. Garment holding members 75, 76, 77 are attached to the upper ends of three U-shaped wooden compartments 16 arranged symmetrically round a rotatable sleeve 11 and attached thereto by U-shaped bars 15 on brackets 14.  The sleeve 11 is intermittently rotated through 120 DEG  by a pinion 40 in mesh with gearing 12 on the lower end of the sleeve, the pinion 40 being mounted on a shaft 39 carrying an intermittent gear 38.  A cone pulley 24 on the shaft of an electric motor 18 is connected with a complementary cone pulley 25, which, on release of a pedal 29 actuating a clutch 28, rotates a shaft 27 carrying a wheel gearing with a wheel 31 on a shaft 32.  The shaft 32 carries a worm 33 meshing with a worm wheel on a shaft 35 on which is mounted an intermittent gear 36 meshing with the gear 38 on shaft 39 which rotates the sleeve 11. A garment is hung on the members 75 &c. and the sleeve 11 then carries the compartment containing the garment through 120 DEG .  In this position the compartment 16 faces a wall 52 with a cover 73 and with swinging side doors 53 which when closed overlap the ends 17 of the compartment walls 16, forming a closed steaming chamber.  Steam is led through a pipe 45 to a conical steam outlet 43 covered with fabric 44 at the bottom of the steaming chamber. Cams 41, 42 are fixed on the shaft 35, the cam 42 being arranged so that just before the sleeve 11 turns it actuates lever mechanism, Fig. 5 (not shown), turning the side doors 53 of the steaming chamber into the open position, in line with the wall 52, allowing them to turn back into their normal closed position under the action of springs after the sleeve 11 has turned.  The cam 41 acts on a valve in the steam pipe 45 through lever mechanism, Fig. 7 (not shown), and is arranged to turn on the steam immediately the sleeve 11 has completed its turn.  In the drying station the garment is exposed to a descending stream of warm air from a pipe 4 which passes down inside the sleeve 11 to a housing 2 containing a rotary blower 23 driven from the electric motor 18, which draws air through a passage 7 into a housing 5, where the air is warmed in passing under the bottom 8 of the steaming chamber, and thence to the pipe 4 through a passage 6.  A circular plate 83 is secured at the depending end of the pipe 4, which contains a thimble 81 shaped to direct warm air along the underside of the plate to prevent condensation thereon. The time between each part revolution of the sleeve may be altered by varying the position of the belt on the pulleys 24, 25.
