Patent GB-1013164-A (GB)
Title: Processes for the production of 5-ribonucleotides and 2,3-o-alkylidene ribonucleosides
IPC: C07H19/06
Filed: 1963-04-17
Abstract: Ribonucleosides are reacted with phosphoryl chloride or "hydrolysed phosphoryl chloride" in the presence of a ketone. If the mole ratio of ketone to phosphoryl chloride is less than 5, a 21,31 - alkylideneribonucleoside - 51 - phosphorochloridate is formed and this is hydrolysed with water to form the 21,31-O-alkylidene-51-ribonucleotide which is in turn hydrolysed to the 51-ribonucleotide in aqueous acid medium. If the mole ratio of ketone to phosphoryl chloride is greater than 5, a 21,31-O-alkylideneribonucleoside is obtained; if the excess ketone is then removed and further phosphoryl chloride added and optionally a proton acceptor, the product may be phosphorylated and then hydrolysed as in the first embodiment.  The "hydrolysed phosphoryl chloride" consists predominantly of orthophosphorodichloridic acid HOPOCl2 and may be obtained by treating POCl3 with water or a lower aliphatic alcohol, e.g. in situ, or by hydrogenation of esters. Excess HCl may be removed during the phosphorylation reaction by passing air or inert gas or by partial neutralization with an organic or inorganic base or a molecular sieve, or a proton acceptor such as an ether may be added. Examples describe the preparation of the sodium salts of 51-inosinic and a guanylic acids and of 21,31 - O - isopropylidene guanosine, inosine, adenosine, cytidine and uridine and 21,31-O-cyclohexylideneinosine. Specification 1,011,994 is referred to.

Title: Improvements in or relating to strings of insulators on overhead electric lines or conductors
IPC: H01B17/04
Filed: 1931-05-22
Abstract: 363,952. Overhead cables. PIRELLIGENERAL CABLE WORKS, Ltd., 343, Euston Road, London, and MATTHEWS, C. E., Merrowdown, Avenue Rise, Bushey, Hertfordshire. May 22, 1931, No. 15221. [Class 36.] In order to facilitate maintenance work on overhead line insulator strings, the strings are connected to adjustable tensioning or compressing screws, turnbuckles or hydraulic devices adapted to bridge the strings without need for attachment to the tower. The screw device is held in position by conductor line tension and is adapted to relieve the insulators of tension so that they can be removed. In the construction shown in Fig. 1, a frame comprises sets of side members 2, 21, 3, 3<1>, respectively, the members 2, 2<1> being connected together by a plate 4, and the members 3, 31 by a plate 4<1>. Bolt holes 5 in the plates 4, 4<1> enable the frame to fit strings of different length. The members 21, 31 are pin-jointed to a yoke 7 which is formed with an attachment 8 for bolting it to a socket connector 9. The members 2, 3 are screwthreaded for adjusting nuts 10, 10<1>, 11, 11<1> respectively. Trunnion fittings 12, 12<1>, attached to a yoke 13, are mounted between the adjusting nuts. The yoke 13 is pivoted to a swivel joint 15 on a cross-arm of the tower, the end of the insulator string being attached to the swivel joint 15. In a modified construction the string of insulators is pivotally linked to the joint 15. In the construction of Fig. 3, turnbuckle rods 27, 28 carrying an operating sleeve 29 are attached to adaptors 22, 23 which are secured to yokes 24, 25 at the respective ends of a double string of insulators 26.

Title: Improvements in or relating to devices for moving rail vehicles
IPC: B61J3/00
Filed: 1948-06-05
Abstract: 642,698. Lifting-jacks. WESTON WORKS (BIRMINGHAM), Ltd., PEARSON, D. A., BIRMINGHAM SMALL ARMS CO., Ltd., and FLETCHER, J. June 5, 1948, No. 15240. [Class 78 (iii)] [Also in Groups XXXI and XXXII] A vehicle mover having a frame with handlebars and one or more supporting wheels and a hydraulic jack which during operation is automatically controlled to maintain the lifting head in contact with, and to exert a substantially constant lift on, the vehicle. The vehicle 1 comprises two side-plates 2, a front wheel 3 and a rear wheel 4 and handlebars 5. An engine 6 mounted on the frame drives the rear wheel 4 through a gear-box 7, a sprocket 8, and chain and chainwheel 9, 10. A lifting head 14 is mounted on two side strips 13 which move between two plates 11 mounted on the side-plates 2. A hydraulic jack 19 is supported between the plates 11 and its ram 20 engages the head 14. The jack is connected to a pump unit 21 and has a shaft 22 with a sprocket 24 driven by a chain 25 from the sprocket 26 on the engine shaft. An eccentric 27 on the shaft 22 operates two opposed pistons 28 whereby liquid is drawn from the sump 29 through inlet 30 past non-return valves 31, 32 into a duct 33 to passage 34 to raise the jack. A duct 36 also connects with the tube 33 and has an enlarged part 37 and a seating for a ball-valve 39 and side holes connecting with the sump. A pushrod 41 presses on the ball and has a peg 42 passing through a hole in a leaf-spring 43. The height of the leaf-spring is adjustable by an eccentric to provide for wear. A plunger 56 is mounted in a block 55 on the top wall of the sump and rests on the spring. A lever 57 pivoted to the block has a cam 60 with a flat 59 bearing on the plunger 56. The lever is rotated by a cable 61 from the handlebars against the action of a compression spring 62. Operation of cable 61 rotates the lever 57 to press the piston 56 downwards on the leaf-spring 43 and so move the push-rod 41 on to the ballvalve 39. When there is clearance between the plunger and the flat 59, operation of the pump allows fluid to pass the ball-valve 39 and to return to the sump through the side holes without raising the jack. Further rotation of the lever 57 and cam 60 allows the jack to be operated. The ball-valve acts as a relief valve and when the jack is lowered as a release valve, the cam being then rotated until the flat is opposite the phmger 56 when the fluid can pass the ball-valve and return to the sump. Separate relief and release valves may be incorporated.

Title: Improvements in electric motors
IPC: H02K17/36
Filed: 1960-05-02
Abstract: 978,011. Control of A.C. motors; electric motors. E. F. D. WEBB. May 2, 1961 [May 2 1960; May 16, 1960], Nos. 15361/60 and 17292/60. Headings H2A and H2J. A reversible servomotor comprises a double polyphase induction motor unit in a common casing 1, and with star-connected wound rotors 7, 8 on a common shaft 6, which also carries a rotor rectifier network on a plate 23 and a rotor impedance 37. There is a rectifier bridge for each phase, corresponding windings 11, 17 of each rotor being connected across opposite terminals of each (Fig. 3). As shown, the rotor impedance comprises a single resistor 37, but alternatively there may be an inductor across each bridge, with centre tappings star connected (Fig. 6, not shown). As a further alternative an additional rectifier bridge is connected in place of resistor 37, its output being connected through resistors to the star point of each rotor. The stator windings are arranged to produce opposite rotation and are supplied through controllers 46, 47 from a common source. The controllers may be saturable reactors, induction regulators, gas-filled relays, grid-controlled rectifiers, or silicon or germanium rectifiers, and are adjusted, e.g. by an error signal produced in a valve positioning servo system, so that a greater voltage is applied to the stator corresponding to the desired direction of rotation than to the other. The motor receiving the lower voltage is thus driven by the other and its rotor is effectively open-circuited by the rectifiers. To produce a high torque at low speeds without increasing rotor impedance, each rotor winding may be sub-divided and arranged so that, to a voltage developed in one phase is vectorially added two smaller voltages, e.g. 58% of the first, developed in the other two phases, the polarity of one being reversed; it is shown that this produces a more favourable rotor phase angle. To produce axial movement of the output shaft, to operate a valve, the rotors may be mounted on it by an Acme thread. An electromagnetic brake, held off by the supply voltage, may be provided. According to the first Provisional Specification a single squirrel-cage motor unit produces axial movement of its output shaft against a spring, by a recirculating ball arrangement. The rotor rotates until its torque balances the spring pressure and hence the shaft comes to rest at a position determined by the applied voltage, which can be varied in any of the ways described in the Complete Specification. Two such units may be mounted in line to produce motion in either direction. Specification 978,012 is referred to.

Filed: 1940-10-28
Abstract: 546,902. Actuating clutches; tappet mechanism. POTTER, W. W. Oct. 28, 1940, No. 15794. [Classes 80 (ii) and 80 (iii)] Consists in mechanism for transmitting, at will, intermittent movement to a member from a constantly rotating part, such mechanism being particularly applicable to the actuation of clutches in automatic machine tools. To a shaft 11 adapted to rotate in bearings at the ends of a casing 10 are keyed a number of discs 13 side-by-side. Each disc carries a lug or tooth 14 adapted, when required, to actuate one of a pair of arms 17 of a lever 16 connected by a rod 18 to.the sleeve 20, for example, of a clutch. Two adjacent discs constitute a unit for acting upon one lever and the arms 17 are arranged in different planes, corresponding to the planes of rotation of the teeth 14, each tooth acting upon only one arm and in one direction. The two teeth of a unit are spaced so far apart circumferentially that it is impossible for them to act simultaneously on their respective arms. Within the casing 10 is a liner 21 with slots at 22, 27, 29. The teeth 14 do not act directly upon the arms 17 but through the intermediary of balls 23 which can be released from a chamber 25 to be driven round by the radial face of the tooth 14 until it engages and displaces an arm 17 to move the rod 18 in one direction and bring the other arm 17 into a position'to be struck by the ball, when released, of an adjacent disc to reverse the lever and movement of the rod 18. Each ball is released by lifting its respective spring-loaded lever 37 to withdraw a slide 26 and, after striking the arm 37, the ball is guided at 28 back to the chamber 25. A second slide 260 is provided to hold the ball in case the lower slide is withdrawn. There is a lever for each ball and these levers may be actuated by dogs 380 on discs 38 carried by a power driven shaft 39. A flat spring 40 at the bottom of the chamber 25 prevents jamming of the balls.
