Title: Improvements in taps or valves
IPC: F16K41/10
Filed: 1954-06-08
Abstract: 783,780. Valves. ROBBINS, A. H. Sept. 7, 1955 [June 8, 1954], No. 16772/55. Class 135. In a screw-down tap, which is opened by manual actuation of a threaded spindle 11, comprising a spring 21 to close the tap, the spring being isolated from the liquid controlled by the tap and co-operating with a resilient closure 7 to automatically exert the required force to seat the closure upon the spindle 11 contacting the valve body 10, the closure is a moulded cylindrical washer of resilient material, such as rubber, arranged with its upper end clamped between a body flange and a washer 9. Upon turning the spindle 11 in an anti-clockwise direction by means of the handle 12 the latter engages the head of the centre spindle 14 and through washers 23, 25 lifts the lower part of the closure 7 off the seat 5, whereupon the side wall of the washer bulges outwardly. A guide sleeve 17 and the spring 21 move upwardly with the centre spindle 14 whilst a guide pin 19 in the washer 9, passing through a slot in the sleeve 17 and entering an axial groove in the spindle 14, prevents any turning of these parts and controls the maximum valve opening movement. The handle 12 is rotated in the reverse direction to close the valve, the spring 21 and washer 7 exerting the necessary pressure to force the lower face of the washer against the seat 5. The body portion 10 may be unscrewed to enable the washer 7 or spring 21 to be replaced and a cap may be threaded into the central opening in the handle. In a modification, the spring may be disposed within the moulded washer.

Title: Copolymerisation of ª‡-olefines with arylalkenes
IPC: C08F210/16
Filed: 1965-04-21
Abstract: Copolymers which may be in the form of blocks, of alpha-olefines of the general formula CH2 = CH-R where R is hydrogen, alkyl, aryl, or alkaryl, with arylalkenes of the general formula <FORM:1090750/C3/1> wherein n=0-12, m=1-12, and Ar is an aromatic nucleus, which may be condensed, substituted, or unsubstituted are made by effecting the polymerization of the monomers either mixed or sequentially, in the presence of the reaction product of TiCl4 or TiCl3 with Al(C2H5)3, Al(C2H5)2Cl, and/or Al2(C2H5)3Cl3 in an inert solvent or dispersing agent preferably at a temperature of 30-150 DEG  C., under slightly elevated pressure for 0.5-15 hours.  Specified olefines are ethylene, propylene, butene-1, 3-methylbutene-1, pentene-1, 4-phenyl-butene-1, hexene-1, and styrene.  Arylalkenes mentioned are 4-phenylpentene-1, 4-phenylhexene-1, 4-phenylheptene-1, 5-phenylhexene-1, 5-phenylheptene-1, 4-p-tolyl-pentene-1, and 12-phenyl-tridecene-1. The catalyst can be preformed or formed in situ, and the copolymerization effected in bulk or in a hydrocarbon solvent or diluent.  In the examples, the catalyst is prepared in two stages, i.e. by first reducing TiCl4 with one of the organoaluminium compounds set forth above, and "ageing" this product for 5 hours at 110 DEG  C., and then activating the product with further amounts of organoaluminium compounds.  The polymerization is terminated by conventional techniques, and the copolymer recovered and purified by known methods.  Examples are given of both simultaneous and sequential copolymerization.

Title: System for and a method of computing altimeter setting pressure
IPC: G01L19/08
Filed: 1974-04-18
Abstract: 1470800 Determining altimeter setting pressure SPERRY RAND CORP 18 April 1974 [7 May 1973] 16937/74 Heading G1N A system for computing altimeter setting pressure from local barometric pressure, includes a sensor 13 providing a signal in accordance with local barometric pressure as regards its period, which signal gates clockpulses from an oscillator 17 to a multiplier 21 and counter 24 through gate 16. The multiplier scales the pulse count in accordance with calibration logic 30 to convert the pulse count to a representation of the pressure altitude in accordance with function A, Fig.1. This representation is compared at 31 with the elevation of the airport at which the sensor is sited and the counter 24 is caused to count down or up by input pulses fed from the clock oscillator 17 through gate 37 until the two inputs to the comparator are equal. Multiplier 41 having also received the pulses from gate 37 and passed them to altimeter setting counter 44 the count on this counter represents the difference between the pressure altitude and the elevation. This count is converted to a count proportional to the corresponding standard day barometric pressure by conversion logic 50 in accordance with function B, Fig.1. The output of the converter 44 is telemetered to an aircraft by conventional multi-plexing and transmission techniques, Figs.3-6 (not shown). The sensor may be as in Specification 1228401, Division Gl.

Abstract: 457,206. friction clutches. TAYLOR, L., 22, Thornham New Road, Castleton, Rochdale. June 18, 1935, No. 17461. [Class 80 (ii)] In a friction clutch wherein inner clutch plates 1 are splined on a sleeve 4, a stiff resilient disc a, which is dished, fluted, sinuous, &c. so as to be capable of being flattened under pressure, and which is splined on the sleeve 4, is interposed between the plates and the presser ring 8. The disc a provides compensation for wear and enables the clutch to slip on overload. The ring 8 is moved to clutching position, through toggle units 13 arranged between the ring 8 and a ring 12 adjustably screwed on the sleeve 4, by movement of a sleeve 15, as described in Specification 393,703. The rings 8, 12 are coupled by dowel pins (not shown) so as to rotate together. A ring 6, splined on the sleeve 4, is interposed between the ring 8 and disc a. A locking pin 9 mounted in the ring 8 is urged by a spring 10 into one of a number of holes in the ring 6. Upon withdrawing the pin 9 from the hole, the ring 8 can be rotated until the pin engages in another of the holes, the ring 12 being thus screwed along the sleeve 4 to adjust the clutch. Springs 14 assist the disengagement of the clutch. As shown in Fig. 2, the dished ring a is formed with spaced holes a<1> and slots a<2>. The ring a is of metal or other resilient material such as vulcanized rubber compound, or may comprise rubber compound vulcanized to a metal ring or between a pair of metal rings. A double clutch is also described.

Class 92(ii) A safety device 13 for the firing mechanism of a rocket-launching weapon can be made to occupy three positions. When in the first position shown it prevents complete downward movement of the sear 6 and thereby prevents release of the firing hammer 7; at the same time an upstanding part 23 of the safety device is clear of a bolt 10 which is adapted to hold each projectile in the barrel against movement. The bolt is thus free to move when a fresh projectile is loaded into the barrel. The device 13 is moved to the left-the second position. - by an anti-clockwise movement of a handle 17 and in this position it still prevents the release of the firing hammer and also holds the bolt 10 against movement. In the third position, to the right of that shown, the nose 10 is again free to move and the sear 6 is clear of the abutment surface on the device 13 and can therefore be lowered to free the hammer.
