Abstract: 1,161,039. Temperature indicators. NATIONAL CASH REGISTER CO. Jan. 23, 1968 [Feb.27, 1967], No.3495/68. Heading G1D. [Also in Division H4] A temperature indicator comprises a continuous film 12 of polymeric material having dispersed therein droplets 11 of a liquid capable of assuming a cholesteric mesophase in a predetermined temperature range, and thereby exhibiting a colour change in the light reflected from the droplets. The droplets are preferably of between 5 to 25 microns in size and the liquid preferably comprises a cholestrol derivative, e.g. cholesteryl carbonate or cholesteryl nonanoate, the composition of the liquid being varied to vary the temperature range in which the spectral colour change occurs. The liquids also exhibit irridescence in the associated temperature range. The film 12 preferably comprises polyvinyl alcohol or a polyacrylate material. Other examples of materials for use in the liquid or as the film 12 are given in the Specification. The film 12 may be disposed on a substrate 10 which may be opaque e.g. black, or a coloured layer 13 may be interposed between the substrate and the film 10. The droplets 11 may be disposed as a single layer in the film 12 or may provide a number of layers. Droplets having different colourchange ranges may be disposed in the one film 12.

[Class 57.] Masses 6, 7 pivoted to the engine-driven baseplate 3 are formed with arms 8, 12 of differing length which bear on lever arms 9, 13 secured to the cam 10. The arms 9, 13 are also of differing length, the. shorter arm in each pair being associated with the longer arm in the other. Springs 18, 19 anchored to the baseplate 3 are connected also to arms 15, 16 fast with the cam ; for part of their length they are pressed against the surfaces of the arms 15, 16. The mass 6 by reason of its shorter arm and by engaging the stop 21 ceases to be effective before the mass 7 ; the latter having to oppose both springs produces a smaller adjustment than that obtained at lower speeds. Modifications are described in which superposed weights the one short-armed and the other long are mounted on each of the pins 4, 5, and in which the springs are secured directly to the pivots 4, 5 and the ends of the arms 9, 13. With superposed weights, the upper weights run on balls which rest in grooves in the baseplate and protrude through slots in the lower weights. Pads of antifriction material are also mounted in the baseplate.

Title: Method and apparatus for separating loose solid material according to specific gravity
IPC: B03B5/24
Filed: 1961-11-24
Abstract: 1,009,423. Jigs. STAMICARBON N.V. Nov. 24, 1961 [Nov. 26, 1960], No. 42114/61. Heading B2H. A mixture of loose solid material e.g. raw coal is separated on a perforated support i.e. screens 4, 4<SP>1</SP> in a wet jig 1 into fractions with different specific gravities according to a method in which liquid pulsations are caused by alternately increasing and decreasing the pressure of air in one or more chambers 16 located beneath the perforated support, the upward pulse of liquid in each cycle being brought about by so rapidly increasing the air pressure in the chamber or chambers 16 that the rate of upward acceleration of the liquid reaches 3 m./sec.<SP>2</SP> in less than 100 milliseconds from the commencement of such pulse. The chamber or chambers 16 are fed with air from a supply line 17 by way of one or more admission control valves 18 in the form of flat discs which, or each of which is connected to the piston 30, Fig. 6, of a piston and cylinder unit operating to move the valve towards and away from a resilient seating 32, the movements of the valve being controlled by a cam or cams 24, Fig. 3, through the agency of valves 28, controlling the flow of a pressure fluid to the piston and cylinder unit or units. Raw coal is fed in along a shoot 6 on to the screen 4, the jig being divided into two compartments by a bridge 5. Owing to the liquid pulsations the raw coal is separated into a lower layer of shale and an upper layer of coal and middlings. The shale passes under a gate 8 operated by a float 7 and the coal and middlings pass over the bridge 5 on to the screen 4<SP>1</SP> where they are separated into a lower layer of middlings, leaving under a gate 12 operated by a float 11, and an upper layer of clean coal which is carried off in a shoot 15. The shale and middlings pass down conduits 9, 13 and are removed by a bucket elevator 10. The upward liquid pulsations raises the material fed from the screens 4, 4<SP>1</SP> substantially en masse, the compressed air admitted by the valves 18 pushing the liquid level down in the chambers 16. Before the air reaches the lower edges of the chambers 16 the valves 18 are closed and similar valves 20 connected with exhaust pipes 21 are opened to allow the liquid level in the chambers 16 to revert to its original level before the next cycle begins. The cams 24 are mounted on a shaft 23 driven by a motor 22 whose speed is regulable. The cams actuate switches 26 causing excitation of a coil 27 in an associated electrical cricuit. Each coil 27 controls a valve 28 thus causing opening or closing of the associated valve 18 or 20. The cams 24 are adjustably screwed to the shaft 23 and each comprises two adjacent concentric discs provided with high portions. By relative angular displacement of the discs the timing of the operation of the air admission and exhaust valves. Specification 1,009,424 is referred to.

Filed: 1918-03-09
Abstract: 123,607. Hudd, A. E., and Thornycroft, O. March 9, 1918 Clutches and speed-varying mechanism.-In hydraulic variable-speed gears of the type comprising two sets of cylinders B, G, Fig. 1, parallel to the driving-shaft A and containing pistons acting on swash-plates C, H, the rotatable casing E constitutes the driven member and its speed is controlled by the simultaneous or successive adjustment of members D, L trunnioned in the casing and engaging the swashplates. The sets of cylinders B, G are disposed on opposite sides of a valve plate F secured to the casing and are respectively secured to the driving shaft A and a hollow shaft K, to which the swashplates are connected by universal joints. When the swash-plates are in the position shown, the casing is not rotated, but by inclining the swashplato C and reducing the inclination of the plate H. a gradually increasing velocity is imparted to it, the cylinders G and shaft K being prevented from rotating by a brake acting on a drum K<1>. The highest speed is attained when the plates C, L are in the position of maximum and zero inclination respectively, at which time there is no circulation of liquid. A reverse drive is obtained by inclining the plate C in the opposite direction. The power may be taken off the casing, or by means of a shaft M passing through the shaft K and secured to the valve plate F. The position of the swash-plates is adjusted by means of a handlever Q<1>, Fig. 4, connected to a collar carrying plates N, O sliding in guides on the exterior of the casing, and having cam slots engaging pins on levers connected to the trunnions of the members D, L. The lever also carries a quadrant S having cam projections S<2>, S<3> which act on a lever T<2> to release the brake acting on the drum K<1> at the times when the gear is in the neutral and direct drive positions. A cam member U<1> on a member U may also be moved to release the brake irrespective of the position of the lever Q<1> by means of a pedal U<4>. In addition, if the gear happens to be in the direct drive position, a projection U<5> engages the quadrant S and moves the lever Q' into position for an intermediate speed.
