Patent GB-949487-A (GB)
Title: Sprinklers
Inventor: HARRIS DAVID ALAN
IPC: B05B3/14
Filed: 1961-08-14
Abstract: 949,487. Cup sprayers. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 13, 1962 [Aug. 14, 1961], No. 29244/61. Heading B2F. A sprinkler apparatus comprises a distributer having an inlet and a number of discharge orifices and means for vibrating the distributer so that liquid discharged issues from the orifices and breaks up into drops which are sufficiently large not to result in any substantial spray drift. The distributer comprises four tubes 3, 4, 5, 6 suspended from the frame 2 by webbing strips 7 whereby they can be vibrated in the discharge shown by the arrow A, the vibrations being caused by a cam 12 operated from the engine of the tractor which transports the spraying equipment. Liquid is pumped from a tank 1 into the ends of the tubes through inlets 10. The orifices 3 along the lengths of the tubes may be directly underneath or disposed so as to discharge at an angle between the horizontal and vertical, or there may be a combination of both. The cam 12 may have two or four lobes, or, instead of a cam, electromagnetic means may be used to vibrate the distributer. For dynamic balance, the vibrations imparted to the tubes are such that one pair moves in the opposite direction to the other. Nozzles may be fitted to the distributer orifices, resulting in the liquid breaking up into drops later. If each tube has two or more inlets the pressure drop along it is reduced. Examples are given of results obtained with various combinations of orifice diameter, head of liquid, amplitude and frequency of vibration and number of inlets per tube. There may be one tube only or any convenient number.

Patent GB-784269-A (GB)
Title: Impact clutch
IPC: B25B21/02
Filed: 1955-10-17
Abstract: 784,269. Positive clutches. CHICAGO PNEUMATIC TOOL CO. Oct. 17, 1955 [Jan. 12, 1955], No. 29525/55. Class 80 (2). An impact clutch comprises a rotatable hammer and anvil with means for disengaging and engaging the impact jaws, the means comprising cam elements having rolling contact and arranged for positive movement of the hammer towards the anvil. A pneumatic motor shaft 54 is splined to a hammer member 59 having three projecting portions 104 which drive a dog member 83 having three corresponding jaws 84. The jaws 84 are engageable, when the member 83 is moved to the left, with corresponding jaws 93 integral with an anvil member 64 journalled in a housing 51 and carrying a nut socket 107. A spindle 62 is carried in the anvil 64 and is driven thereby with slight lost motion through pins 71 engaged in semicircular slots in the anvil and wider slots in the spindle. Towards the right-hand end of the spindle is a face cam 97 urged into engagement with a roller 102 by a spring 82, the roller 102 being mounted on ball bearings 101 in the hammer 59. The dog member 83 is located axially on the spindle 62 by balls 88 and spring ring 89. In operation, under light load, the dog member 83 and spindle 62 are urged to the right, and drive is transmitted from the shaft 54 through the hammer 59 to roller 102 which contacts the cam 97 to drive the spindle 62 and thence, through pins 71, the anvil 64 and socket 107. Increasing resistance to the rotation of socket 107 causes cam 97 to ride against the roller 102 and face the shaft and dog member to the left, the jaws 84 contact jaws 93 of the anvil and give a blow to socket 107. As this occurs, the roller 102 is free from the cam 97 and over-runs it, the lost motion connection at 71 allows easy release of the jaws 84, 93 and the dog member returns to its original position. As long as the resisting torque on the socket 107 continues in excess of a predetermined figure, the dog member continues intermittent engagement with the anvil at every revolution of the hammer member. In another embodiment, Fig. 19, the cam action is provided by balls 148 riding in V-slots in a dog member 134 and a cam element 126, the cam element being driven at light torques by a key 154 urged out of a slot in the spindle 128 by a spring 156. Relative rotation between the dog member 134 and spindle 128 causes a camming groove 159 to move the key out of drive with the element 126, and thus relieve the balls 148 of impact torque. In a modification of the first embodiment, Fig. 43, means are provided for lubricating the mechanism through a lubricator 178, reservoir 179 and passages 182, 183. In this modification, the dog member 167 is secured for free rotation on the spindle 168 by a ring of balls 169 engaging semicircular section grooves in the two members. The balls are inserted through a drilling 174 and are retained by a plug 173 which is itself retained by a keeper-pin 176.

IPC: G21C5/10
Filed: 1956-10-01
Abstract: 827,751. Nuclear reactors. GENERAL ELECTRIC CO. Ltd., and SIMON-CARVES Ltd. Sept. 26, 1957 [Oct. 1, 1956], No. 29925/56. Class 39(4). A circular grillage for supporting the reactor core within a spherical pressure vessel 7 comprises longitudinal members 2 spaced by short members 3 to form squares, the grillage being supported on the top 10 of an annular foundation 4. The members 2, 3 have flanges 8 welded along their lower edges and are shaped at 12 to have reduced height where they extend over the foundation at the points A . . . F, the grillage being encircled by a ring 11. The core is carried within a flange 6 on a top plate 5 and means are provided to ensure that the load is evenly carried by the foundation 4 at the points A . . . F. For instance the points F in Fig. 3 would tend to take the greatest load, the load gradually diminishing towards the points A, owing to the varying distances between the points A . . . F and the positions where a member 2 or 3 encounters a cross member. Thus the load would cause greatest deflection at the points A and least deflection at F. To even out the load reaction packing pieces, Fig. 5 (not shown), are introduced between the members 2, 3 and the foundation 4, the pieces diminishing in height from the points A towards the points F, thus providing gaps 13 having a maximum value at the points F between the grillage and the foundation, in the absence of the predetermined load upon the plate 5.

Title: Improvements in and relating to apparatus for basing electric lamps
IPC: H01J9/30
Filed: 1952-11-27
Abstract: 709,896. Capping electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 27, 1952 [Dec. 1, 1951], No. 30088/52. Class 39 (2) A nozzle for use in extruding cement on to the inner walls of caps or bases for electric lamps comprises a central tube or core 31 with a radial jet or jets 32 near its closed lower end, and a pair of concentric sleeves 36, 37 fitting around the core and biased downwardly by helical springs 38, 39 respectively, so that the jets 32 are normally covered by the inner sleeve 36, the outer sleeve having an inwardly projecting shoulder 46 arranged to abut against an outward shoulder 45 on the inner sleeve and displace the latter to uncover the jets after the outer sleeve has been displaced a predetermined extent through pressure exerted against it by the rim of a cap. The relative dimensions of the cap and the parts of the nozzle are such that the lower end of the inner sleeve 36 is within the neck of a cap when the jets are uncovered due to the cap being lifted upwardly and pressed against the outer sleeve 37. As a result a ring of cement 13, Fig. 2, is positioned below the edge of the cap and leaves a clear clean band 14 upon which a leading-in wire may be soldered. As shown the filling nozzle 20 is associated with an intermittently indexed carrier 21 of the turret type provided with cap-receiving cavities 23, and is mounted above one of the positions at which a cap is halted, the cap being then above a cup or socket 26 mounted on the upper end of a spindle 25 which is reciprocated vertically to lift the cap into engagement with the nozzle. While in its upper position the spindle 25 is rotated through one complete revolution or long enough for a complete ring of cement to be applied to the inside surface of the cap. Cement from a reservoir is supplied under pressure through a screw-threaded fitting 34 at the upper end of the tube 31.

Abstract: 844,059. Electric analogue calculating systems. LINK AVIATION Inc. Oct. 3, 1956 [Oct. 12, 1955], No. 30142/56. Class 37. An analogue computor continuously produces a voltage respresenting R s = h<SP>2</SP>/R s +R g + R G  (Fig. 1) where R s  = slant range, h=altitude and R G = ground range of an object, e.g. an aircraft, with respect to a fixed point A, e.g. a radar station. A constant voltage E is applied across a square low potentiometer R-2 adjusted by an altitude actuator Ah whereby a voltage proportional to h<SP>2</SP> is applied to a summing amplifier U-1 via R-4, U-1 having a high open-loop voltage gain and polarity inversion; the output of U-1 is applied to potentiometer R-1 adjusted by ground range actuator A RG  whereby a voltage proportional to R G  is applied to the input of U-1 via resistance R-5; the output of U-1 is also supplied to potentiometer R-3 adjusted in accordance with the computed slant range and the resulting voltage applied to input of U-1 via resistor R-6. Amplifier U-1 is such that its output is caused to represent -h<SP>2</SP>/R G +R S  which is the difference between slant range R s  and ground range R G , this output is applied via resistance R-7 to a conventional servo-amplifier U-2 where it is summed with inputs from potentiometers R-8, R-10 representing R G  and R s  respectively; potentiometer R-8 being supplied with a constant negative voltage and R-10 with a constant positive voltage. The output of U-2 drives servo M-1 which adjusts R-10 until the sum of the servo amplifier inputs becomes zero at a balance position wherein the servo output shaft rotation corresponds to R s  and operates an indicator on a potentiometer slider to represent R s  in electrical or mechanical form. The potentiometer R-2 is replaceable by two cascaded gauged linear potentiometers. The servo M-1 may be equipped with a stabilizing tachometer generator or other feed back means and with mechanical limit stops or switches. In navigation and gunnery computations, the actuator A h  may be an altimeter on the altitude output shaft of radar apparatus. The analogue computation may be A.C. or D.C, operated and may be substituted by mechanical, hydraulic or pneumatic equivalent computing elements.

Title: Polymers or copolymers containing phosphorus
IPC: C08F30/02
Filed: 1957-09-25
Abstract: Phosphorous-containing polymers are prepared by polymerizing a vinyl phosphonic acid dihalide alone or with another olefinically unsaturated compound with the exception of vinyl chloride, in the substantial absence of water, i.e. not exceeding 5 mol per cent based on the phosphorous-containing monomer.  Examples of copolymerizable compounds are styrene, nuclear- or chain-substituted alkyl styrenes, divinyl benzene, vinyl esters of organic acids, vinylidene chloride, butadiene, acrylonitrile and esters of acrylic and methacrylic acids. Temperatures of -50C. DEG  to +200 DEG C. may be used and a catalyst is preferably employed, e.g. benzoyl, lauryl, caproyl, caprylyl and tert. butyl peroxides, tert. butyl perbenzoate and azoisobutyric acid dinitrile, or ultra-violet light.  The polymers are viscous to hard products which give off hydrogen halide on exposure to air and react with water.  The homopolymers are soluble in various solvents, e.g. acetone and methylene chloride.  The copolymers are generally crosslinked and sparingly soluble, although there are described (Example 4) a copolymer of vinyl phosphonic acid dichloride with acrylonitrile which is soluble in dimethyl formamide to give a solution from which filaments are prepared, which after treatment with hot water could be dyed; and (Example 5) a copolymer of the dichloride with methyl methacrylate which is soluble in benzene. The products are useful as flameproofing agents, textile assistants, and wetting or emulsifying agents.  Specification 865,047 is referred to.
