Title: Improvements in and relating to centrifugal electric switches
IPC: H01H35/10
Filed: 1938-05-25
Abstract: 504,678. Centrifugal switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 25, 1938, No. 16631. Convention date, May 25, 1937. [Class 38 (v)] A centrifugal switch for cutting out the starting field winding of an electric motor is actuated by a member controlled by weights which move outwards against springs and have arms pivotally connected with the actuating member. Arms 26 of two weights 20 engage holes 29 in a collar 27 slidable on a shaft 12 of a rotor 11. Fixed to the shaft 12 is a disc 21, lugs 22 of which engage holes 23 in the weights 20 which move outward under centrifugal force against springs 31 stretched between fingers 30. The collar 27 is moved axially along the shaft until the leverage of the springs 31 about the lugs 28 is less than the centrifugal force of the weights 20 about the pivotal lugs 28. The collar 27 finishes its movement with a snap action away from the resilient switch arms 44 to allow contacts 46 and 37 to separate and cut out the starting winding. Below a predetermined speed the spring tension causes the collar 27 to move and close the switch with a snap action. Specification 500,778 is referred to.

Title: Improvements in or relating to devices for applying closures to containers, bottles or the like
Inventor: PODESTA ARMANDO
Filed: 1952-06-23
Abstract: 711,005. Closuring bottles &c. VETRI INDUSTRIALI SOC. AR.L. June 23, 1952, No. 15730/52. Class 125 (2) In a closuring machine for containers, bottles or the like supported by springs 2 and having a fixed curling die 3 brought into action by depression of the container R by a presser plate 4 engaging the cap C, spreading of the peripheral. part of the cap is prevented by annular jaw 5 which is depressed to such a level that its working edge extends below the container mouth and which 'fits within the upper part of die 3. The plate 4 is carried on a stem 7 carried by a plate 8 which is vertically reciprocated. A block 6 is screwed on stem 7, is acted on by springs 9 engaged by the plate 8 and is transversed by bores in which work the stems of bolts 10 carrying the jaw 5. In operation, the plate 8 descends and, through the springs 9, causes the plate 4 to engage the cap and start the curling. The plate 8 then engages the bolts 10 and causes the jaw 5 to engage the edge of the cap and the curling is completed. If desired, the jaw 5 may descend before the plate 4. The last motion between the bolts 10 and the plate 8 may be varied The die 3 and the jaw 5 may be made up of sections. An annular or disc-shaped gasket G'is provided. The die 3 may be constructed to curl only spaces sections of the cap skirt. The gasket may be disposed between the cap skirt and the outer wall of the container. In a modification, Fig. 9, the vertical wall of the jaw 105 has spaced notches 205 in alignment with raised points 303 on the curling die 103. This leaves areas of less compression in the gasket G and hence allows excess pressure within the container to be relieved. The container support may be rendered adjustable by providing it with co-acting concave and convex bearing surfaces.

Title: Improvements in making rubberized fibre articles
IPC: D04H1/645
Filed: 1931-05-30
Abstract: 369,474. Rubber-bonded fibrous compositions. BROOKES, N. E., 1, Quality Court, Chancery Lane, London.-(Dewey & Almy Chemical Co.. ; Harvey Street, North Cambridge, Massachusetts, U.S.A.) May 30, 1931, No. 15875. [Class 70.] Fibre reinforced rubber articles are made by impregnating a felt or fleece of fibres with aqueous rubber dispersions such as latex containing a dormant coagulant preferably ammoniated zinc chloride and activating the dormant coagulant for example by heat to coagulate the latex. The dispersions may also contain vulcanizing agents and inert materials such as ground wood fibre. Salts of cadmium, magnesium or calcium mixed with protective colloids such as casein and haemoglobin may be used as coagulants. The impregnated fibrous sheet F is treated during its passage through a conduit C with steam jets S to coagulate the latex superficially, after which the sheet passes to a tank T containing hot water W on which it floats to complete the coagulation. The tank may be supplied with steam from a pipe S' and the water may contain a coagulant such as zinc chloride. After leaving the tank T the product is pressed to remove excess liquid, washed with water, pressed, dried and compacted by pressure. Partial impregnation may be effected by flowing the latex on to a moving fibrous sheet and applying heat to the upper or lower surface. When latex containing comminuted fibres is used a product resembling suede leather is obtained by buffing the rubberized fibre surface. Specification 273,991, [Class 70, Indiarubber &c.], is referred to.

[Also in Group X] A co-operating ramp and a ramp-engaging member carried by the adjoining ends of a pair of sections of an open front mast which can be telescoped after it has been lowered to the ground serve to raise the ends of the legs 7, 8, Fig. 6, of the upper section from a position in end-toend relation with the legs 3, 4 of the lower section to permit the upper section to be telescoped into the lower section. As illustrated, the ramp 21 is carried by the lower legs 8 of the upper section and engages a roller 20 extending between the legs 4 of the lower section. Rollers 24 on the upper section cooperate first with tracks 23 on track plates 22 secured to the lower section and subsequently with the flanges 5 of the legs 3. The tracks 23 are more steeply inclined than the ramp 21 so that the weight of the upper section assists the initial telescoping action. After the ramp 21 leaves the roller 20 the upper section is supported from the lower section by a gentle incline 31 which rests on the roller 20 and by engagement of the rollers 24 with the flanges 5 of the legs 3. Rollers 32 on the upper section are guided by inclines 34 on the lower section to the outside of the mast where they bear on horizontal flanges of the legs 5 after the centre of gravity of the upper section has passed the roller 20. Flanges on the rollers 24 continue to engage the vertical flanges 5 of the legs 3 after the rollers 32 have moved into engagement with their horizontal flanges. An incline 35, Fig. 3, near the crown rides on to the roller 20 at the end of the telescoping action. The sections are secured together by pins 12, 15, Fig. 8, which take through tongues 10, 11 and 13, 14 on the legs 3, 4, 7, 8 and are held captive by pin and slot connections to spring-biased channel members 42, 52 within which they are housed when not in use. The mast may be telescoped by lines from the cathead 27, Fig. 3, or by anchoring the travelling block in the lower section. It is extended by a sling 36, Fig. 8, anchored to arms 37 on the upper section and passing over pulleys 38, 39 on the lower section to the cathead 27.
