Title: Improvements in and relating to snap action electric switches
IPC: H01H35/34
Filed: 1954-08-04
Abstract: 790,848. Fluid actuation of switches. IGRANIC ELECTRIC CO., Ltd. Aug. 4, 1954 [Aug. 5, 1953], No. 22618/54. Class 38 (5). A snap-action switch is operable by changes in a variable, fluid pressure as described, and has a member movable in dependence on such changes to one or other of two positions, there being a leaf spring engaged by the member in moving to one position to resist such movement of the member, the spring being biased against a stop with a variable force so as to vary the operating differential of the switch. As shown, the member is a lever 52 having arms 53, 53a and a cross-piece 55 pivoted on a member 54. The lever is biased clockwise, Fig. 3, by a spring 35 adjustable by a screw 37, and is movable anti-clockwise by a diaphragm 66 The upper end of the lever is connected by tension springs 75 to the lower end of a lever 70 pivoted at 71 in brackets 31, 31a, which are attached to a separator plate 13 fixed to casing walls 12, 12a. The leaf spring 20 has an aperture 19 receiving a part 18 of a bracket 16 carried by plate 13 and is notched at 21 to engage an adjusting nut 25 on a screw 26, the centre portion of the spring being urged against a stop 27 formed by part of bracket 16. When the pressure increases, the lever 52 moves anti-clockwise and through the dead-centre springs 75 moves the lever 70 clockwise. This lever carries a spring blade 78 having forked ends engaging contact operating bars 100, 100a which loosely carry contacts 91, 92 normally bridging fixed contacts 84, 84a, 85, 85a. Such clockwise movement of lever 70 thus opens the contacts. When the pressure falls again, lever 52 returns clockwise and a portion 57 thereof engages the spring 20 and slows down the movement before the springs 75 move overcentre again to swing lever 70 anti-clockwise to reclose the contacts.

Abstract: 825,068. Endless belt conveyers. MOAR, J. Oct. 17, 1957 [July 25, 1956], No. 22923/56. Class 78 (1). A conveyer consists of an inclined flume 2 through which water or other liquid is passed, and an endless belt 5 adapted to float together with a load 19 of material on the liquid in the flume and further adapted so as to be propelled by the flow of liquid. The flume consists of a rectangular section inclined trough 10, 11 into one end of which the liquid is passed, e.g. by diverting a stream. The belt 5 consists of a floor 14 having flotation chambers 15 formed on either side, these chambers containing either air 16 or a solid medium 17, e.g. foam rubber or plastic or kapok. The underside of the belt has secured to it either rearwardly-opening flexible pockets 26, Figs. 2 and 4, or blocks 34, Fig. 5, on which are pivoted flaps 30 adapted to be retained by the liquid flow in the operative position shown. The liquid impinges against the flaps 30 or enters the pockets 26 to propel the belt along the flume. Where curves are to be negotiated vertical idler rollers 25 are provided within the flume to engage the sides of the belt. At the ends of the flume the belt is passed around reversing rollers, the return run extending either below the flume, Fig. 2, or within the flume below the load-carrying run (Fig. 3, not shown). In either case the return run is carried on idler rollers 22 and held in position on these rollers by vertical idlers 24 engaging the sides of the belt. In a further construction, Fig. 6, the flume is divided into two by a longitudinal partition 36 and both runs of the belt float on the liquid, the belt passing around a vertical axis roller 37 at each end of the flume. The liquid may flow in both sides of the flume since the pockets 26 or flaps 30 collapse when the belt is moving against the liquid flow.

Title: Improvements in or relating to governor mechanisms
IPC: F16H61/00
Filed: 1957-07-25
Abstract: 850,295. Change-speed control, FORD MOTOR CO. Ltd. July 25, 1957 [July 25, 1956], No. 23567/57. Class 80 (2). Governor mechanism for obtaining a fluid pressure 156 proportional to the rotational speed of a member such as the output shaft of an automatic transmission on a vehicle, for controlling ratio-shift therein, comprises a positive displacement pump driven by the output shaft and delivering through a Venturi to a passage 148, from which total pressure 144 (including velocity head) and static pressure 146 (excluding velocity head) act in opposition on the ends of a differentially-landed regulator valve-spool 154 to meter supply pressure 150 from an inputdriven pump into a governor pressure passage 156 in response to output speed in accordance with a desired pressure-speed characteristic. Exhaust parts 220, 222 are provided. By providing an increased diameter end plug 224 (Fig. 2, not shown) this characteristic can be changed from upwardly concave to linear. By providing an additional spring opposing the plug 224 above (Fig. 4, not shown) the curve is divided into two portions having different slopes. In Fig. 3, not shown, the pressure tappings are both static and taken respectively from the upstream and downstream sides of the Venturi, which increases the slope of the characteristic in the high speed region by reducing the effect of fluid friction. The automatic transmission, not described, includes one or more shift valves subject to opposing pressures responsive to vehicle speed and engine-throttle setting.

Filed: 1961-06-29
Abstract: 948,846. Spinning apparatus. JAMES MACKIE & SONS Ltd. June 21,1962 [June 29, 1961], No. 23588/61. Heading D1D. In spinning apparatus of the two-for-one inflow type having a flyer which balloons the sliver around a package on to which the yarn is wound, a false-twist tube is carried round with the flyer in the sliver path and is rotated around its own axis in the direction necessary to allow the twist which is put into the sliver on the delivery side of the flyer to run back past the tube into the sliver on the feed side of the flyer. A disc flyer 14 carries a twist-tube 12 which acts as the flyer eye, the flyer being driven by a shaft 30 and a gear 28. A tube 16 is rotatably mounted in a bracket 78 carried by the flyer and is held stationary as observed in Specification 948, 847 by a fixed gear 82 which is connected to a gear 80 fast with the tube through gears 86, 84 on a shaft carried by the flyer, the gears 82, 86 and 80, 84 being connected by endless belts 88. As the flyer rotates, the upper belt 88 runs in contact with a gear 92 fast with the twist-tube to rotate the latter. As described in Specification 948,845; the tube 16 carries a bracket 76 carrying a pair of yielding nip-rollers 18, the receiving spindle 4 and associated parts as well as the drive to the latter and the rollers from a gear 44 through a gear 60 loose on the tube. In operation, sliver 2 is fed from a drafting mechanism 6 by delivery rollers 8 so an eye 10 and thence to the twisttube 12 and to the package 20 through tube 16. The twist running back from the tube 12 strengthens the sliver on the balloon, where but for the tube it would have only half the final degree of twist. The tube may be such or so driven as to further strengthen the yarn by inserting a turn or turns of the false twist. The rollers 18 merely serve to tension the yarn, so that the degree of twist inserted may be varied by changing the speed of the rollers 8. Accordingly, the drive for the rollers 18 may be as in Specification 948,847.

Title: Improvements in or relating to nuclear reactors
Inventor: SMITH ROBERT ARTHUR
IPC: G21C7/12
Filed: 1961-06-29
Abstract: 960,170. Controlling reactors. BOLLSROYCE & ASSOCIATES Ltd. June 13, 1962 [June 29, 1961], No. 23630/61. Heading G6C. [Also in Divisions F2 and H2] A nuclear reactor control rod is coupled, through electromagnet means which on de-energization releases the rod for rapid insertion into the reactor core, to a feed member in the form of a lead screw engaging a nut device located against movement in the direction of the length of the screw and rotatable by a vernier motor whereby accurate control of the position of the rod can be effected in the course of normal reactor operation. The vernier motor (cf. Division H2) is housed in a casing 13 (Fig. 2A) and has a rotor 16 which can be moved in small angular steps, a key 19 connecting the rotor 16 and a spindle 17 so that they rotate together. At the upper end of the spindle 17 is a nut device 25 of the recirculating ball type which engages a lead screw 27. The lead screw extends downwardly into a casing 12 and carries at its lower end (Fig. 2B) a housing 31 containing the energizing coil 32 of an electromagnet fed with current by a cable 33. The armature 35 of the electromagnet is connected in a manner described below with a rod 10 (Fig. 2C) carrying at its lower end a series of blades (not shown) of neutron-absorbing material. A plate 38 and a downwardly extending tube 39 (Figs. 2B, 2C) which houses a spring 40 surrounding an hydraulic shock absorber are secured to the armature 35. .The shock absorber has a piston member 41a secured to the plate 38 and a relatively telescoping cylinder member 41b formed at its lower end with a bored swelling 42, the bore of which receives a pin 43 the ends of which engage bosses 44 formed internally of a guide sleeve 45 encircling the tube 39, the bosses 44 projecting through slots 46 in the lower part of the tube 39. The spring 40 at its upper end bears against the plate 38 and at its lower end against a flange 41c on the lower end of the cylinder 41b, thus tending to elongate the shock absorber 41a, 41b. The lower end of the tube 39 has an end fitting 51 to which is secured the upper end of the rod 10. The lower portion of the casing 12 houses a resilient buffer 54 consisting of a stack of metal and rubber rings arranged alternately and bonded together. The rod 10 may be inserted rapidly into the reactor core under scram conditions by de-energizing the electromagnet coil 32 so freeing the rod 10 from the lead screw 27 whereupon it falls under gravity. During this movement, the guide sleeve 45 engages the buffer 54 so stopping the cylinder 416, further downward movement of the tube 39 and rod 10 causing telescoping of the shock absorber 41a, 41b and compression of the spring 40, so cushioning the fall of the rod 10. In the event that the tube 39 and rod 10 tend to travel downwardly past the position shown, a flange 45a on the guide sleeve 45 abuts an auxiliary buffer comprising a ring 48 bonded to a rubber annulus 49 which is in turn bonded to a ring 50 fitted on the tube 39.
