Title: Expansible pulley for progressive change speed transmission
IPC: F16H55/54
Filed: 1930-10-21
Abstract: 371,797. Expanding pulley gearing. THELINGE, H., 46, Boulevard Leopold II, Heyst-sur-Mer, Belgium. Oct. 21, 1930, No. 31571. Convention date, Oct. 23, 1929. Void [Published under Sect. 91 of the Acts]. [Class 80 (ii).] An expanding pulley comprises tread segments 15 with slides 20 rigid therewith adapted to slide in radial slots in a pair of inner discs 13, and elongated or round bowls 16 pivoted on the ends of the treads and adapted to slide or roll within curved slots in a pair of outer discs 10. The inner discs 13 are secured to a hub 12 loose upon an inner hub 8 to which the outer discs 10 are secured. The hub 8 is fast on a sleeve 6 loose on a pivot shaft 4 supported in a control frame 5 pivoted on a driving shaft 1. The shaft 1 is connected to the sleeve 6 by a toothed pair 2, 3. The treads 15 are shaped to take a flat or other belt or rope which transmits the power to a driven pulley (not shown). Relative rotary motion between the radially and the curved slotted discs causes the treads 15 to move radially in unison and there is at any time equilibrium between the thrust of the belt compressing the treads inwards and the load reaction on the curved slots tending to cam them outwards. Speed is varied by moving the frame 5 about the shaft 1 so as to move the expanding pulley towards and from the driven pulley. The frame 5 is suitably lockable. An arrangement is described with receiving and transmitting expanding pulleys constructed as described with their radially-slotted discs coupled to rotate together, the whole being supported to rotate freely on a pivot shaft such as 4 supported in a pivoted frame such as 5 under manual control.

Filed: 1959-09-16
Abstract: 976,981. Stud and socket fastenings. BRISTOL AEROJET Ltd. Dec. 15, 1960 [Sept. 16, 1959(2)], Nos. 31580/5 and 31647/59. Heading E2B. [Also in Division G6] A coupling between upper and lower parts 31, 32 of a nuclear reactor control rod comprises a casing 35 slidable on the lower part 32 to an extent limited by axial slots 36 receiving the ends of a pin 37 secured to the part 32, the casing being biased by a spring 38 acting on a casing flange 40. In the coupling engaged position, Fig. 2, the pin 37 is held in the centre of the slots 36 by a latch 41 pivoted in a slot 42 in a sleeve 43 secured to the part 32, the latch having a 90 degrees notch at each end, one notch having latching engagement with the flange 40 whereby upward movement of the casing 35 is restricted. In this position balls 44 contained in holes in the sleeve 43 prevent the withdrawal of an enlarged head 47 of a nick 46 on the upper part 31. A plunger 48 biased by a spring 49 is carried within the sleeve 43. To disengage the coupling the part 31 is moved downwards to push the casing 35 and disengage the flange 40 from the latch 41, the head 47 simultaneously depressing the plunger 48 so that a claw 51 therein rotates the latch to the Fig. 3 position. When the part 31 is raised the spring 38 lifts the casing the full extent of the slots 36 so that a groove 57 in the casing is opposite the balls 44, Fig. 4, and the head 47 may be withdrawn therethrough. Simultaneously, the flange 40 turns the latch 41 to the vertical position. To re-engage the coupling the part 31 is lowered to depress the casing 35 whereby the balls leave the groove 57 and eventually the head 47 depresses the plunger 48 whereby the claw 51 rotates the latch 41 into the Fig. 2 position.

Abstract: 281,326. Friedlõnder & Co., (Assignees of Fuchs, P.). Nov. 27, 1926, [Convention date]. Composition fuel.-Non-coking fuels other than low temperature coke are briquetted by means of a binder consisting of a mixture of inorganic and organic substances. Up to 6-7 per cent of inorganic binder which consists of sorel cement or lime slaked with magnesium sulphate solution, and less than 3 per cent of organic binder (calculated on the dry substance) are employed. In an example the fuel is mixed with an aqueous solution of the pitchy product from the evaporation of sulphite liquor and the inorganic constituent is then incorporated. The 'material is then briquetted hot or cold and allowed to harden. The briquettes contain e.g. 1-1.2. per cent of organic substance, and 4-6 per cent of inorganic binder. Naphthalene may be used as a dry organic constituent., 1-2 per cent being employed with 4-6 per cent of the inorganic binder. Or 1-2 per cent of tar may be substituted. The inorganic binder which may be caused to set in about seven hours in the briquettes are heated to 60-120‹ C. Magnesium oxide may be mixed with the quicklime before slaking in proportions varying according to the hardness desired.
