Title: Improvements in or relating to electrophoretic coating
IPC: C09D5/44
Filed: 1969-07-30
Abstract: 1,267,601. Electro-phoretic deposition of resins. CHEMISCHE WERKE ALBERT. July 30, 1969 [Aug. 20, 1968], No.38286/69. Heading C7B. A synthetic resin is electrophoretically deposited on to a conductive article, e.g. a steel or an Al sheet, from an aqueous suspension of the resin containing one or more of polyvinyl phosphonic acid, its Na salt and phosphoric acid, as defoamer, e.g. in an amount 0À1-5% by weight of the resin. Octyl alcohol may be added as defoamer. The process is effected at a temperature below the softening point of the resin, e.g. between ambient temperature and 50C. The suspension may also contain a pigment which may be contained in the resin, e.g. powdered below 30 microns size, by stirring it into a melt of the resin, cooling and grinding. The coating, e.g. more than 100 microns thick, may be heated above the resin softening point. The aqueous medium may contain a cationic, anionic or non-ionic wetting agent in an amount 0À01-5% by weight of the resin, such as an alkyl (e. g. Na lauryl) sulphate or sulphonate, or an alkyl (e.g. nonyl) phenol polyglycol ether. The resin, e.g. 2-50% by weight of the suspension, may be a condensation, polymerization, or an acrylic, epoxy, urea or amine (e.g. melamine) resin. Preferably phenolic (e.g. a resol or novalak) resin; polyester resin based on an aliphatic or aromatic carboxylic acid having up to 18C, e.g. (tere-or iso-)phthalic, adipic, sebacic, maleic or fumaric acid, and a polyhydric alcohol, e.g. (di)ethylene glycol, glycerol, trimethylol-propane or -ethane, dimethyl propanediol, a butane- or hexane-diol; a polyamide, e.g. polycaprolactam, polyhexamethylene adipamide, poly-beta-lactam or polyundecanoamide; or a homo- or co-polymer of an olefin having more than 2C is used. A current density of 0À1-30 mA/cm<SP>2</SP> and a voltage of 5-200 volts D.C. may be used.

Abstract: 1,056,174. Drafting condenser r o v i n g s . COTTON SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. Dec. 29, 1964 [Sept. 30, 1963; April 16, 1964], Nos 38369/63 and 15716/64. Headings D1D, D1F and D1N. In producing a yarn from a condenser roving, real twist is imparted into the roving before it is drafted, and the twisted roving is drafted over a length sufficiently large compared with the staple fibre length that substantially all the real twist remains in the drafted roving. The roving may be twisted by feeding the roving from the condenser to a spinning pot with optionally omitting the rubbing leathers, by a separate step of feeding the roving to a spinning pot, or by rotating a cheese of an untwisted roving as the roving is unwound therefrom in the drafting frame. The roving is preferably drafted by frictional contact only with the drafting rollers-i.e. without roller nips. In the apparatus shown, two rovings may be drafted at a time on rollers 20-23 having roller parts 24, 25, driven by rubber-surfaced rollers 26, 27. The roving R is drafted in three steps between roller parts 21a and 23b, 23b and 21b, and 21b and 23c. Each drafting roller is peripherally grooved. Instead of, as shown, the roving being initially and finally frictionally held by roller parts 21a and 23a, and 21c and 23c, roller parts 23a and 21c may be replaced by separate rollers Fig. 3 (not shown) adjacent rollers 21 and 23 respectively. The roving may be false twisted whilst being drafted to increase or decrease the amount of twist during drafting. The drafted roving is wound on a ring spindle unless there is sufficient twist already in the roving.

Blowers 56, 58 are connected to a source of pressurized air and operate such that the trailing end of the label is precluded from dropping too early on to the container upper surface. The blower 58 turns the tab 32 of the label downwardly and the label is then pressed on to the container upper surface by a leaf spring 62. A pair of brushes 66 apply the tab 32C to the container side. Each support frame 72 of a pressure and conforming assembly 71E on the endless belt 70 has a reciprocable plunger 74, conforming pads 76 and an adapter arm 78. A cup 80 is mounted on the plunger for engaging the container upper surface and the arm 78 is mounted in pantographic relationship to the frame 72. The frame is cammed towards the container by the action of a roller 106 against a camming rail 104 and the container reacts against the cup to force the plunger upwards inside a guide 103 until the pads are brought into contact with the label and container. In an alternative embodiment, Figs. 7, 8 (not shown), a second camming rail (108) is provided so that frangible or crushable containers may be labelled with the reaction forces caused by applying pressure to the container being absorbed by the mechanism (114A).

Title: Improvements in remote-control installations for gate-valves, especially gate-valves on ships such as oil-tankers
IPC: F15B11/02
Filed: 1961-10-31
Abstract: 929,370. Valves. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE S.I.G.M.A. Oct. 31, 1961 [Nov. 7, 1960], No. 38955/61. Class 135. In order to prevent jamming in the closed position of hydraulically operated, remotely controlled gate valves, e.g. valves in oil tanker ships, arrangements are made for the operating liquid supplied to the jacks of the valves to be at a lower pressure for closing the valves than that supplied for opening them. In an embodiment, two gate valves 1, actuated by jacks 4, are controlled by respective, remote valves 48 fed by a conduit 22 from a common source of pressure liquid and also by a conduit 51 connected to the source through a pressure reducing valve 50. The left-hand valve 48 is shown positioned to connect the lower side of the jack of the lefthand valve 1 to the conduit 22 and the upper side to exhaust 137 for opening the valve whilst the other valve 48 is shown positioned to connect the upper side of the jack of the other valve 1 to the reduced pressure conduit 51 for closing the valve, the lower side of the jack being connected to the exhaust 137. Rotary valves 61 are provided for interrupting the connections between the valves 48 and the jacks and connecting the latter to hand pumps for manual operation of the valves 1. The valves 48, which have spring plungers 58 to locate them in either of their two positions, may be modified to have an intermediate position so that the valves 1 can be brought to rest at any position, and in this case position indicators operated by pistons displaced by fluid exhausted from the jacks are provided. The valves 48 shown are associated with indicators 39 which have plungers 43 raised only when fluid is being exhausted from the jacks. These indicators may be mounted in the valve housings which may be constructed so that a number of housings can be joined together. A pressure regulator 50 may be interposed between each valve 48 and its jack instead of the single valve 50 on the supply side of the valves 48. The pressure source employs electrically driven pumps 10 and accumulators 15 &c.

Abstract: 1332658 Helicopter rotors; aircraft propellers UNITED AIRCRAFT CORP 13 Aug 1970 [18 Sept 1969] 39155/70 Headings B7W and B7V In a variable length blade of telescopic form  adapted to be used with similar blades to form a variable diameter rotor or propeller, the outer blade portion is caused to telescope with respect to the inner blade portion by jackscrew action  and is connected to the jackscrew by a plurality of tension-torsion members extending between the outer blade portion and a series of nuts on the jackscrew. The blade may be used in either a helicopter rotor or the propeller of a fixed wing aircraft. In a preferred embodiment, as shown in Fig. 6, outer blade portion 106 is caused to move telescopically with respect to inner blade portion 104 along feathering axis 26. Individual nuts 100a-100e threadably engage jackscrew 66, and tension-torsion members 110a-110j extend between the nuts and the tip of outer blade portion 106 where they engage a plate member 140. The tension-torsion members 110 are of the wire or rod type and of circular crosssection, and extend through drilled holes in the nut assembly 100 and plate member 140. Two members 110 attach to each nut and pass through aligned clearance holes provided as required in the adjacent nuts, having heads 150 at one end and nuts 152 threadably engaging the opposite ends. In operation, as the nut assembly is caused to translate on jackscrew 66, outer blade portion 106 moves telescopically with respect to inner blade portion 104 because each of the nuts is individually connected to the tip 112 of outer blade portion 106 through tension-torsion members 110. These nuts are substantially equally loaded due to blade centrifugal force during rotor operation since the members 110 constitute a soft spring with respect to the nuts and deform under centrifugal load. In addition, due to the length and torsional flexibility of members 110, blade outer portion 106 can vary in pitch without imparting rotational motion to the nut assembly 100, since members 110 will twist around feathering axis 26 during blade pitch change before friction forces on the nuts are overcome. It is necessary that the nut assembly 100 be of sufficiently small size and selected shape to allow the blades to change pitch without contacting the nuts. The members 110 can be made of steel in single or multiple strands, fibre glass or boron, and the nut assembly 100 of good wear resistant material, e.g. a beryllium copper alloy.

Abstract: 1,272,956. Digital computers; telephones. P. LUCAS; J. DUQUESNE and R. COURTOIS. 8 Aug., 1969 [8 Aug., 1968], No. 39877/69. Heading H4K. [Also in Divisions G4-G6] A digital computer for telephone switching systems can operate in two modes: firstly under a series of stored instructions from a read only programme store 1, and secondly under a series of non-stored real time instructions (fundamental instructions) determined by the state of monitoring flip-flops 61. A multiregister 5 holds scan words, one of which is transferred to read out register 6 and activates line scanner 26 which tests the state of points in the switching systems. The word in register 6 is rewritten according to the test results using write-in register 7 and controls the state of the flip-flops 61. Means are provided to change over from the first mode to the second and back again. An interruption sub-programme can be inserted between two instructions of the first mode, or two fundamental instructions of the second mode, following a call from peripheral units having a known priority arrangement. The computer of British Patent Specification 1,155,249 is modified so that the fundamental instructions are not drawn from the programme memory but instead are characterized by the state of the flip-flops. First mode 32 bit words are read from store 1, each word comprising 1 to 3 orders of 10 bits each, a u bit for address progression and a # bit for interrupt. These are read in instruction register 3 and pass to function decoder 4, which is also connected to the monitoring flip-flops 61. Second mode.-Two series of independent operations are performed in parallel and three fundamental instructions IF0, IF1, and RD use the same time periods t0-t3 as the first mode instructions but two cycles t0-t3 are allocated to each fundamental instruction. Interrupt.-A series of first mode instructions can be fed in from a peripheral unit inbetween the usual first or second mode instructions, and when the interrupt is complete the computer reverts to its original mode. For an interrupt to be allowable, the bit v of the first mode word should equal 1, or the flip-flop SP should be inoperative for the second mode. While interrupt occurs the contents of read-out register 6 and write in register 7 pass to register 5 and the contents of address register 14 into the auxiliary register 14<SP>1</SP>. After interrupt the contents are returned to their original positions. Time base circuitry is also described (Fig. 7, not shown).
