Title: Automatic weighing machine with dial and with additional weights controlled by levers
IPC: G01G1/26
Filed: 1945-08-24
Abstract: 604,937. Weighing-apparatus. RECSI SOC. ANON. Aug. 24, 1945, No. 21795. Convention date, July 14, 1943. [Class 143] A dial automatic weighing machine has additional weights for altering its capacity controlled by levers pivoting on a fixed axis, on one side of which is provided for each lever a return spring and a weightsuspension rod, the lever having profiled rear faces to form cams controlling indicating mechanism, and grooves or locking parts engaging plungers controlled by key levers, the cam levers being provided on the other side of the axis with a part adapted to contact a cam to lift them and facilitate their engagement with the plungers. The beam carries an arm 4 which supports weights 7 by knife-edges 8. These weights are connected to rods 12 pivoted to cam levers 15 which pivot on pins 16 of fixed supports 17. Rotation of a cam 14 on shaft 13 by means of a crank arm 38, Fig. 5, raises the cam levers against springs 18 to the Fig. 1 position with the weights 7 raised. Levers 20 having keys 45 are pivoted at 24, and pawls 25 at 22. Plungers 27 engage the levers in the raised position and carry pins 30 controlled by the levers 20. Other plungers 32 contact the levers 15, and the stops 48, Fig. 5, of a weightindicating device comprising an arm 42 spring 43, and carrying a rod 47 hinged to a pivoted sector 56, Fig. 1, connected by a rod 58 to a lever 60, Fig. 3, pivoted at 61 and hinged at each end 72 to a rack 62 engaging a pinion 63 which carries a disc 65 inscribed with the weight-figures. As shown in Fig. 1, weighings from 0-1 kg. are registered on the dials 67. To weigh between 3-4 kg., key 45 having the numeral 3, Fig. 5, is depressed whereby lever 20 retracts plunger 27 so that it disengages from lever 15 which drops and lowers its weight 7 on to knifeedges 8. Levers 20 are provided with overlapping feet so that all having numerals lower than that depressed move with it releasing their weights, in the present case a total of 3 kg. The lug 26 of the pawl 25 moves downwards on actuation of levers 20 and 15 and holds plunger 27 to allow its subsequent engagement with lever 15 on the return thereof. The plunger 32 moves from its stop 48 allowing a displacement of arm 42, rods 47, 58, and lever 60, displacing discs 65, Figs. 3 and 4 (not shown), which display respectively, the limits of the weight range. To set the machine to its original position, crank 38 is turned to raise levers 15 and weights 7.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/07
Filed: 1957-07-10
Abstract: 860,131. Photographic shutters; diaphragm adjustments. GAUTHIER G.m.b.H., A. July 10, 1957 [July 10; 1956], No. 2.1902/57. Class. 98(1) In a photographic shutter with diaphragm. blades which are opened to a pre-selected aperture before the shutter' blades; are opened and are closed after; an exposure, the diaphragm blades are mounted on two co-axial and relatively rotatable rings of which one is adapted to be actuated by a manually operable diaphragm setting member and the other; through a driving means connecting it to the first ring is adapted to be rotated in the same direction and by the same amount as the first ring, and a. further driving means is provided which can be tensioned prior to release of the shutter and can be released in dependence on the release of the shutter, the further driving means moving the second ring relatively to the first ring to open the diaphragm to the pre-selected stop valve. The shutter shown is of the kind in which a shutter blade ring 10 is reciprocated by a spring-driven master member 4 to open and close the shutter blades. This shutter also includes diaphragm blades 18, each being pivoted at 21 to a ring 20 and having pin and slot connection with a co-axial ring 19. A spring 34 tends to keep a projecting arm 20a from ring 20 in contact with a lug 19b on ring 19, an arm 19a on which is constantly engaged with a pivoted lever 26 by a stronger spring 30. Lever 26 engages a cam 26 on a diaphragm setting ring 22 so that manual rotation thereof moves ring 19 and, because of spring 34, ring 20 to positions corresponding to the diaphragm aperture required. Such movement of rings 19, 20 does not open the diaphragm blades. The shutter is released by a lever 14 which moves a pin 42 on a spring-biased lever 41 out of the path of a driving lever 35 which thereupon pivots under spring action into engagement with a pin 44 on the arm 20a projecting from ring 20 and so rotates the latter to open the diaphragm blades to the pre-selected aperture at which they are held open by contact of a lug 20b on arm 20a with the end 46a of a pivoted lever 46. Lever 35 continues to pivot and strikes a latch 13a to release master member 4. This member then opens and closes the shutter blades and, at the end of the closure movement, pivots lever 46 away from lug 20b so that ring 20 can return under the action of spring 34 to close the diaphragm blades 18.

Title: Improved gas distributing apparatus
IPC: G05D16/06
Filed: 1924-09-16
Abstract: 237,453. Deckers, J. F. Sept. 16, 1924. Indicating leaks. - Gas from a high pressure reservoir 1 is reduced to a low pressure suitable for lighting, heating or power purposes by passage through a valve 4, the spindle of which is operated by a lever 7. The main distributing pipe 9 is fitted with a cut-off cock 10 and checkvalve 12 and is connected to the base of a bellows 13. The pressure in the pipe 9 is regulated by the application of weights 15 to a guided rod 17 which is secured to the top of the bellows and engages the lever 7 by means of a pin and slot connection 14. In event of an excessive fall of pressure in the pipe 9 such as would be caused by a leak or rupture in the distributing pipes, a lug 24 on the lever 7 engages a red 23 attached to a spring-pressed lever 21 and thereby actuates tension tongs 20 to release a shackle 19 which is drawn upwardly by a spring 18. In its upward movement the shackle 19 lifts the lever 7 and closes the valve 4.

Abstract: 361,942. Attaching articles to arm &c. ; straps. TEAGUE, E. D., of Dunlop Rubber Co., Fort Dunlop, Erdington, Birmingham. July 22, 1930, No. 22048. [Class 43.] In straps for attaching articles such as wristlet watches to the person or for analogous purposes wherein a strap 1 is made entirely or principally of rubber or a compound thereof, initial adjustment of the length or tension, or both, on attachment, is obtained by providing an adhesive surface on one or more parts whereto another part may be secured as by bringing together under pressure subsequent to engagement with an article. The ends of the strap may be chamfered or tapered as at 1a, Fig. 1, and the adhesive surface may be protected as by glazed linen 1c whereon the rubber is calendered. This surface, prior to use, may also be moistened with petrol. Such surfaces may be provided at or adjacent the ends which may be threaded through loops 2 of a watch 3, Fig. 2, turned back and secured as at 1b. Adhesive surfaces may be provided on opposite sides so that two ends may be directly joined as at the back of a watch after passing them through the loops. In this case only limited initial adjustment, determined by the extent of the adhesive, is possible. The strap may carry at one end a hook or clip for detachable connection. the other end being secured as described above after initial adjustment. The hook may be attached by a loop on the strap fixed by adhesive or it may be partly embedded in the strap. The hook may be wholly or partly covered with fabric which may extend into the rubber and thus serve as an anchoring medium. Detachable connection at one end may also be effected by stiffening or supporting the rubber so that it may be bent into hook shape. Ductile material such as pensteel may be embedded in the rubber for this purpose, and it may be enveloped in fabric anchoring it in the rubber. Sheets of rubber may be calendered sufficiently thin and brought together round the stiffening material prior to being moulded into straps. The strap may be in two parts connected by a device such as a buckle and may be reinforced by incorporating canvas or the like. Moulding of the straps may be accomplished in multiple moulds bearing any pattern and the straps may be made in various colours to simulate other materials. Where one end of the strap is attached to a metal fitting, adhesive rubber may be dispensed with and the adhesive surface provided by a cold curing solution. According to the Provisional Specification metal fittings such as hooks may be provided at both ends of the strap.

Abstract: 721,543. Sanding bricks, tiles, &c. JOHNSON, J. A. Dec. 15, 1952 [Sept. 20, 1951], No. 22090/51. Class 87 (2) Bricks or a column of clay which is subsequently to be cut in bricks are fed on to a conveyer 16 which carries them through a hopper 34. Granular material, e.g. sand or powdered glass, is fed into the hopper through a wire-mesh screen at the top. The hopper is mounted on resilient mountings 36 and is vibrated by an electric motor 41 in order that the sand may be evenly distributed over the bricks. Rubber strips 37 restrict the escape of sand. Heating elements 46 are provided to warm the sand and thus soften the' outer surface of the bricks to facilitate the embedding of the sand therein. Excess sand is removed by fixed or resiliently mounted scrapers 47, 48 and 49, 51 and falls into a trough 53 having a right- and left-hand worm conveyer which feeds the sand towards the centre of the trough. A spring- 86 urged roller 85 forces the bricks down into contact with the sand in the trough 53 to sand the bottom surface of each brick. After sanding, the sand is forced into the bricks by beater plates 62, 63, 65 which are vibrated by cams. In a modification, the plates are replaced by rollers, which may be heated. The bricks are separated from each other to facilitate their removal by tilting the conveyer 17 upwards by a roller 87.
