Title: Nuclear reactor control rod control systems
Inventor: PERKS ELTON JOHN
IPC: G21C7/14
Filed: 1959-11-06
Abstract: 961, 927. Reactor control rods. SPERRY GYROSCOPE CO. Ltd. Aug. 19, 1960 [Nov. 6, 1959], No. 37725/59. Heading G6C. [Also in Division H2] A control rod drive motor can drive the rod in either of two directions, can be held electromagnetically in a desired position, or can let the rod fall relatively unimpeded by the motor, the rod is hung by a metal tape or other flexible support from a winding device driven by the motor. Fig. 2 shows a control circuit for a vernier motor, i.e. one in which a rotation of the magnetic field of stator coils 13, 14, 15 causes a much smaller rotation of the rotor. The motor is driven by an alternating current or by a series of direct currents; a steady current in one or more coils, e.g. from battery B, will hold the rotor in a desired position. Disconnection of power by a switch S1 allows the control rod to fall freely. Specifications 847,718 and 961,926 are referred to.

Title: Means for reversing the traverse of the cam carriage of an automatically operating flat knitting machine
IPC: D04B15/64
Filed: 1971-08-12
Abstract: 1321507 Knitting machines H STOLL G STOLL E STOLL E STOLL J STOLL A STOLL R E STOLL and M STOLL 12 Aug 1971 [27 Aug 1970] 37819/71 Heading D1C In a flat knitting machine, a reversing arrangement for the carriage which is driven through roll gearing, comprises on the gear casing a lever 4 carrying rollers 5, 6 and an associated spring biassed lever 7 which, during operation, biasses one of the rollers into engagement with an abutment rail 15 during a traverse while, at the end of the traverse, the other roller engages a braking bar 17 to slow the carriage down and then a locking pawl 20 to push the lever past dead centre and initiate reversal of the carriage. Lever 4 is carried on a pin 3 rotatably mounted in a gear casing 1 is coupled to roll rings therein pressed against drive shaft 2 so that radial adjustment of the pin 3 determines the angular adjustment of the roll rings and therefore the speed of travel of the carriage. A pivoted spring-loaded lever 19 above each bar 17 is held in position by the spring-loaded pawl 20. In operation, lever 4 is inclined rearwards at an angle α as the carriage moves from left to right. When roller 6 engages bar 17 and gradually diminishes turning pin 3 and varying the angular position of the ring rolls to reduce the speed of travel of the carriage gradually to zero. When roller 6 strikes pawl 20, it frees lever 19 and shifts lever 4 beyond its dead-centre position until roller 6 bears against the guide bar 24 and lever 4 pivots until roller 6 engages rail 15 and lever 4 is at an angle # to its new direction of travel, movement of the roller rings having caused reversal of the carriage drive. The angles α and # and therefore the carriage speed are determined by the position of rail 15. Reversal thus takes place at a precise point i.e. when pawl 20 is released. (For Figures see next page)

Title: Removal of catalyst residues.
IPC: C08F6/02
Filed: 1968-08-08
Abstract: 1,179,065. α-Olefin polymerization and purification. UNIROYAL Inc. 8 Aug., 1968 [31 Aug., 1967], No. 37841/68. Heading C3P. Alpha-olefin copolymers are prepared by copolymerizing in a solvent using a solventsoluble catalyst comprising (a) an alkyl aluminium halide, (b) a vanadium compound the ratio of (a) to (b) being at least 5:1, and (c) a nitrogen-containing oxidant as a catalyst activator and/or polymerization regulator, and the resulting copolymer solution is substantially freed of aluminium and vanadium compound catalyst residues by (d) adding a catalyst removal adjuvant comprising a polyether diamine, a polyether monoamine or a polyether glycolalkanolamine mixture and (e) washing with water. The compounds of type (c) are organic nitro compounds, N-oxides, organic nitrates, nitrites, azoxy compounds, and nitroso compounds. The purification may include evaporation of the solvent, and the washing step may be effected by spraying or atomizing a mixture of water and polymer solution at an elevated temperature and pressure above the surface of a body of agitated hot water, into which the polymer particles fall and may subsequently be separated. In the examples, ethylene-propylene co- and ter-polymers with dicyclopentadiene are obtained by polymerization in the presence of (C 2 H 5 ) 3 Al 2 .Cl 3 /VOCl 3  and 2-nitropropane, nitrobenzene or bisethyl 4,4<SP>1</SP>-azoxydibenzoate, followed by treatment with polypropylene glycol diamine, various polyether monoamines of the formula where R is a tallow, coco or stearyl radical, or mixtures of polypropylene glycol or polybutylene glycol with mono- or di-ethanolamine or methyl- or t. -butyl-diethanolamine or diethylethanolamine.

Title: Article dispensing apparatus
Inventor: WINNETT ARTHUR EDWARD
IPC: G07D1/00
Filed: 1968-08-08
Abstract: 1,224,240. Coin dispensing apparatus. ADVANCE DATA SYSTEMS Ltd. 30 July, 1969 [8 Aug., 1968], No. 38002/68. Heading G4X. [Also in Division A4] A coin dispenser comprises a tubular magazine of circular cross-section and a dispensing mechanism, said mechanism having separable sections, a first of which is lockable to the magazine so that the interlocked combination of magazine and said section leaves no opening through which a coin large enough to fill the magazine cross-section may be extracted. The first section 9 fits within sides 7 and 8 of the magazine and is locked in place by rotation of a D-section shaft 19 in slots 20. The shaft 19 is retained in the position by a lock 23. The coins to be dispensed are forced through a block 25 into a space defined between a surface 28 and the top of the block, which space is closed by a rear wall 30, and by side walls 31, 32. Locking members 36 have a lost motion connection with the shaft 19 such that when the shaft is locked to the magazine, clockwise movement of the locking members is prevented and the coin discharge opening 26 is blocked. The interlocked parts are insertable into a housing 3 having a lock 24 with a part 62 which slides axially to bolt the housing door 59 and at the same time inserts key 63 into lock 23. Locking lock 24 by a key 65 thus unlocks lock 23 and turns shaft 19 to release locking members 36 thereby permitting the dispensing of coins. Turning of shaft 19 to this position also locks it in slots in the second dispenser section. A member (68) (Fig. 7, not shown) on the door prevents the sliding of part 62 and hence the locking action above unless the door is closed. A plunger 13 running in guides 39 ejects coins when reciprocated by rocking of a lever 40 which is pivoted to an arm 42 pivotable through angle a. When coins are to be dispensed a solenoid 46 is energized to pivot a lever 47 anticlockwise so that it abuts and forms a fulcrum for the lower end of lever 40. Subsequent anticlockwise movement of arm 42 causes lever 40 to pivot anticlockwise about its lower end and actuate the plunger 13. A latch 48 engages a projection 40a on lever 40 to retain lever 47 in its abutting position after de-energization of the solenoid. The upper end of lever 40 has a roller spring- retained in recess in the plunger, and the linkage disengages if the coins jam so as to prevent damaging the apparatus. When the dispenser magazine is empty a switch 54 actuates warning devices. The coins may be forced up the tube by the spring means shown or by fluid pressure. Two coin tubes are shown, each with its own dispensing mechanism.

Abstract: 1,173,510. Machines for washing beer kegs &c. BURNETT & ROLFE Ltd. 9 Aug., 1968 [18 Aug., 1967], No. 38125/67. Heading B8T. A machine for automatically washing beer kegs includes a detector 21 disposed within an outlet passage 18 of a head 3 connected to the keg, so that after the supply of washing liquid and subsequent supply of steam, the detector causes a control device to initiate a further operation of the machine only when the detector detects the absence of washing liquid at any temperature in the outlet passage. On applying the head 3 to the neck 2 of an inverted keg, supply passage 17 communicates with the interior of spear 4, and the inside of the keg 1 communicates with outlet passage 18 via perforations 15. After washing liquid is passed into the keg via passage 17 it is forced through the outlet passage 18 by steam that is also admitted via passage 17. When probes 22, 23 of detector 21 detect a drop in the electrical conductivity due to the removal of all the liquid from the keg and passage 18, a signal is transmitted to a control device (not shown) to initiate a further operation of the machine. An alternative form of detector can be used responsive to the dielectric properties of the fluid. Reference is made to Specification 1,151,245.

Title: Process for the stretching or contracting of a material web
IPC: B31F1/18
Filed: 1965-09-08
Abstract: 1,069,620. Stretching or shrinking webs. A SCHMIDT. Sept. 8, 1965 [Sept. 17, 1964; Aug. 17, 1965], No. 38368/65. Headings D1S and D2A. A web-of for example paper-is stretched or shrunk by pressing the web against a travelling stretchable band and increasing or decreasing the pressure as the band and web moves forwards so as to cause the degree of stretch of the band to increase or decrease and thus the web to stretch or shrink. The band may be of rubber and be stretchable in both the longitudinal and cross directions, or the stretch of the band may be prevented in one direction (to produce a web shrunk or stretched in only the other direction) by having inextensible cables worked into the band in the requisite direction. There may be two bands 2 as shown, with a pressure cabinet 4, which has pressure chambers 7. . 7d, inside each band. The chambers are connected to a gas pressure source and may have a lubricant-glycerine supplemented by molybdemum di-sulphide-added thereto, the pressure in the chambers increasing in either the upstream or downstream direction. The chambers are mounted on screw-threaded spindles so that they can be moved towards or away from one another. Alternatively there may only be one cabinet 4, which is of semi-cylindrical form, fitting around a drying cylinder which may be one of a series of drying cylinders, the web passing either between a single band (Fig. 7, not shown) and the cylinder which has a friction free surface of nylon, polytetrafluoroethylene, or chromium, or between two bands (Fig. 9 not shown). In the embodiment of Fig. 9 the pressure chambers are formed by elastomeric containers connected to a pressure source, there being plates, which are mounted to be movable radially of the cylinder, and possibly a travelling steel band between the elastomeric containers and the outer band. In Fig. 12 (not shown) the stretching of the band passing between a semicylindrical pressure cabinet and a drying cylinder is supplemented by tentering rolls gripping straps (383), Fig. 13 (not shown), on either side of the band at the edges thereof, the band being reinforced by a woven insert at the edges. Sealing members 10, 12 are provided for the pressure chambers, with an inflatable hose member being located contiguous with the band on the outside of the chambers. In the embodiment of Fig. 12 a travelling sealing belt is arranged between the hose and band, the belt having a grooved surface engaging complementary surfaces in the hose and guide rollers to prevent lateral movement of the belt. In a variation (Fig. 22 not shown) there are two hoses with accompanying belts on each side of the pressure chambers, there being a gap between the hoses which is pressurized at pressures corresponding to the pressures in the adjacent chambers, and also in this variation there is a layer of felt pinned to a rubber belt which is glued or vulcanized to the stretchable belt so that the felt can absorb moisture from the web. A hot air jet is provided to dry the felt layer.

Abstract: 1311404 Image pick-up tubes; phoioconductive devices TOKYO SHIBAURA ELECTRIC CO Ltd 17 Aug 1971 [17 Aug 1970] 38589/71 Headings H1D and H1K A photoconductive target comprises a first layer comprising photoconductive cadmium selenide, a second layer comprising a cadmium salt of an oxy-acid, and a high resistance third layer comprising a compound other than cadmium selenide. Typically the layers are deposited in the above order on a nesa glass signal electrode. The first layer may consist of CdSe which is substantially pure or doped with copper, silver, gold, indium, gallium, aluminium, halogens, tellurium antimony, bismuth, lead, tin, or alkali or alkaline earth metals. The second layer, which is preferably less than 2000  thick, may consist of the cadmium salt of selenious acid with or without an admixture of cadmium oxide, while suitable materials for the third layer, which may consist of a number of sublayers, are one or more of zinc sulphide, arsenic dier tri-sulphide, arsenic tri-selenide, germanium selenide, thallium sulphide or selenide, bismuth trisulphide or selenide, zinc selenide, cadmium telluride and antimony trisulphide or selenide. For solid state scanning the target may be additionally provided with strip electrodes on the third layer and for improved resolution the signal electrode may also be divided into strips. The targets exhibit lower dark currents varying less with ageing while retaining the sensitivity of known targets. A typical target is made by first vacuum depositing CdSe, then heating it for 15 minutes at 600 C, in nitrogen, for 30 minutes at 500 C. in Se vapour, and then heating in nitrogen containing oxygen and selenium vapour and cooling rapidly to form the selenious acid salt. Finally zinc sulphide is vacuum deposited to a thickness of 0À1 Á. Alternatively, after deposition the cadmium selenide is heated at 500 C. for 10- 50 minutes in nitrogen containing oxygen and selenium and the oxygen and selenium content reduced to zero while cooling rapidly. In this case the third layer is arsenic triselenide vacuum deposited to a thickness of 0À4 Á. Another way of forming the cadmium salt is by heating the selenide layer to 300 C. in the presence of selenium dioxide. A single crystal slice of the selenide may be stuck to the nesa glass in place of the deposited layer.

Title: Improvements in or relating to small arms and mortars
IPC: F41C27/06
Filed: 1929-12-17
Abstract: 340,756. Smallarms; projectiles. HENIUS, E. and ARNTZ, H. A., (trading as PETERSEN & HENIUS, A.), 21, Bernstorffsgade, Copenhagen. Dec. 17, 1929, No. 38647. Convention date, Dec. 18, 1928. [Classes 9 (i), 92 (i), 92 (ii), and 119.] Relates to small mortars attached to the muzzle of smallarms for the discharge of grenades, and consists in arranging the axis of the mortar at an angle to the axis of the gun barrel so that the mortar may rest on the ground at the correct elevation while the gun is held substantially parallel with the ground. As shown in Fig. 2, the mortar 1 is pivoted at 11 on a plate 10 attached like a bayonet to the muzzle of a gun 13. A plate 8 on the mortar rides against the plate 10 and can be clamped thereto by a nut 25, in accordance with the desired angle between the axis of the mortar and the axis of the gun, said angle being indicated by a pointer and a scale on the plates 10, 8 respectivelv. The base 2 of the mortar has a socket 3 in which a tube 4 is fitted transversely to bear on the ground to take up the back thrust when the mortar is fired. The firing is performed by the discharge of a shot or blank cartridge from the gun. This rocks a plate 19 about a pivot 18 and makes it strike a firing-pin 33 on the grenade, after which the plate 19 is returned by a spring 20. The grenade, Fig. 7, comprises an explosive container enclosing a central tube 28, to the base of which is attached a primer 38 and a propellent charge 37, while the firing-pin 33 is mounted at the front end against a spring 34 and is normally held at safe by a split pin 31a. The firing-pin when struck by the plate 19 after the removal of the safety pin fires the primer 38, igniting the propellent charge 37. A front sight is formed at the top of the plate 19. The pivotal connection between the mortar and the gun may be such that the mortar can be set parallel with the gun for use against a sloping bank. The angular adjustment between mortar and the gun may be made from the stock end of the gun by means of a rod extending backwards from the mortar and provided with a spike adapted to be driven into the ground, or with a screw adjustable in a nut on the gun, or with a lug adapted to be fitted into one or another of a number of holes in a bracket on the gun, in which case the rod is made in two parts connected by a right- and left-handed nut device for fine adjustments.. In a modification of the firing-device, a rod correspending to the firing-pin 33 is mounted in the side wall of the mortar and operates a pivotal firing-pin in the base of the mortar. In another modification, the grenade has a tubular extension in line with. the gun barrel, and the gases or bullet issuing from the gun barrel strike this extension to cause ignition of the propellent charge. In still another modification, the friction member of a friction fuze on the grenade extends in front of the gun barrel and is operated by the gases or bullet issuing therefrom to ignite the propellent charge.
