Title: Improvements relating to automatic shuttle change looms
IPC: D03D45/34
Filed: 1949-11-12
Abstract: 688,470. Automatic weft replenishing looms. WALKER, H. D., and ESKDALE, J. Feb. 12, 1951 [Nov. 12, 1949; Aug. 3, 1950], Nos. 29019/49 and 19366/50. Class 142(iii) In a loom in which the lowermost shuttle in a vertical magazine is transferred to the shuttle box by a spring-urged loader forming part of the front of the box, the loader is held in a forward position beneath the magazine by a latch actuated by the weft feeler and the spring attached to the loader has an over-centre motion to retain the loader in its forward position when the slay is at back-centre, a cam and roller being provided to hold the loader forward as the slay moves forward. When a weft feeler F indicates that the weft is almost exhausted, a projection on a member F<SP>5</SP> is not moved away from a rod F<SP>8</SP>, lifted by a cam, and a rod F<SP>2</SP> is rotated to raise a member F<SP>3</SP> thereon which raises a catch C<SP>8</SP> having a hooked end C' that engages a pin C<SP>6</SP> on the loader C and holds the loader forward while the slay moves back. On the next forward movement of the slay, a roller C<SP>10</SP> on an arm C' on the loader engages beneath a fixed cam C<SP>11</SP> and keeps the loader forward. The latch C' falls under the action of the weft feeler and when the roller C<SP>10</SP> passes round the large end of the cam a spring C' moves the loader towards the slay and the lowermost shuttle is transferred to the box. A plate, having arms B' and moved by the engagement of a member B‹ with the loader when the loader is initially moved forward, allows the lowermost shuttle to fall on to a plate B<SP>8</SP>. The initial forward movement of the loader also moves a tappet C<SP>12</SP> away from a thrust nod E' bearing on one end of a two-armed lever E<SP>5</SP> and a spring E<SP>6</SP> on the second arm E<SP>4</SP> then rotates a shaft E' and turns the swell E across the path of the incoming shuttle so that the shuttle is deflected and enters a trunk E<SP>10</SP> in which it is stopped by a buffer E<SP>11</SP> and falls into a shoot A roller E<SP>8</SP> also guides the deflected shuttle. A cam G<SP>11</SP> on the side of the loader moves a lever G' connected to a bracket G<SP>3</SP> to which one end of the check strap is connected so that the picker is withdrawn to admit the new shuttle. A weft fork may indicate the need for weft replenishment. According to the first Provisional Specification the shuttle tips engage grooved plates in the magazine and spring means hold the shuttle after release until moved by the loader.

Abstract: 1472421 Carboxy-functional silicones DOW CORNING CORP 2 July 1974 [15 April 1974] 29256/74 Headings C3T C3R and C3B A copolymeric organopolysiloxane consists essentially of (a) from 10-65 mol per cent of siloxane units selected from in which R is selected from and divalent C 1 -C 7  radicals composed of C, H and S, the S being present in the form of thioether linkages, and R<SP>1</SP> is methyl, phenyl or vinyl, and (b) from 35-90 mol per cent of units of the formula R<SP>1</SP> n SiO (4-n) / 2  in which R<SP>1</SP> is as defined above and n=1-3; at least 30 mol per cent of all the siloxane units having a degree of substitution of 1, said copolymer having an overall degree of substitution of 1À2-1À8 with from 15-55% of the total substituents present being phenyl groups. The siloxanes are prepared by the hydrolysis and condensation of the corresponding chlorosilanes to obtain a siloxane containing at least 10 mol per cent of vinyl-functional siloxane units which is then reacted with a mercapto acid in the presence of a free radical catalyst. The siloxanes can be reacted with a nitrogenous base, e.g. NH 3 , an aliphatic amine or an alkanolamine, to improve its dispersibility in water. The above salts can be used in forming aqueous coating compositions with other water-dispersible resins such as polyesters and acrylics, which may also contain dyes or fillers such as SiO 2 , TiO 2 , talc, mica, carbon black, aniline dyes and powdered metals. The siloxanes can also be used as curing agents for epoxide resins. In Examples 1 and 2 siloxane resins containing varying amounts of (CH 3 )(CH 2 =CH)SiO units are reacted with thioglycollic acid in the presence of t-butylperbenzoate or benzoyl peroxide as catalyst to yield siloxanes containing units. The resulting siloxanes are reacted with N,N - dimethylethanolamine or triethylamine. In Example 3 a paint composition is prepared from TiO 2 , Ramapo Blue pigment, a waterdispersible oil-free polyester, methoxylated melamine (crosslinker), water, glycol monobutylether, triethylamine, N,N-diethylethanolamine and a siloxane copolymer comprised of HOOC.CH 2 S.CH 2 CH 2 SiO 3 / 2  units, (CH 3 ) 2 SiO, (C 6 H 5 ) 2 SiO and (CH 3 ) 3 SiO 1/2  units in butoxyethanol.

Title: Circuits for operating electric discharge lamps
IPC: H05B41/18
Filed: 1974-07-02
Abstract: 1511237 Supply circuits for discharge lamps GENERAL ELECTRIC CO Ltd 24 June 1975 [2 July 1974] 29290/74 Heading H2H In a circuit for operating a discharge lamp FL, a change in the phase of the voltage across the lamp with respect to the phase of the supply voltage occurs when the lamp is ignited. When the supply is connected to terminals I 1 , I 2 , a triac TR 1  is repeatedly fired in each half cycle at an instant when the potential at point A is sufficient to break down a Zener diode ZD 1  or ZD 2 . Thus a series of heater current pulses are supplied to the lamp filaments H 1 , H 2 , each pulse being followed by a high voltage pulse which occurs when the triac switches off each time the current through it falls to zero. The high voltage pulses are caused by the back e.m.f. across a ballast inductance L 1 . The lamp rapidly strikes and the voltage across it leads the supply voltage by 90 degrees due to the reactance of the ballast L 1 , C 1 . Thus the potential at A is always less than the peak value of the supply voltage and never reaches a value sufficient to fire the triac TR 1  so that the supply of current to heat the filaments H 1 , H 2  is cut off.

Patent GB-798501-A (GB)
Title: Improvements in fluidised chemical processes and apparatus therefor
IPC: C22B1/10
Filed: 1954-10-12
Abstract: In fluidized chemical reactions in which agglomerates are formed, e.g. the production of producer gas, combustion reactions, or the carbonization and gasefication of solid fuels, said agglomerates are mechanically removed through the surface of the bed whilst maintaining the fluidized condition thereof.  A suitable reactor includes a conveyer in the form of an inclined grating upon which the fluidized bed is supported, which traverses the lower part of said reactor and means for passing a fluidizing gas through said grating. In the embodiment shown in Fig. 1 and described in relation to the production of producer gas, the solid reactant as "fines," preferably mixed with soot emanating from de-dusting of the smoke, is fed to a fluidized bed 11 in a furnace 14 from a hopper 16 feeding a shovel wheel 17. Fines could alternatively be insufflatd with air.  Granular materials may also be introduced through the reactor walls into banks or slopes of non-fluidized material formed as described below.  The bed rests upon a mechanical grate 6 operated by driving rollers 8 <PICT:0798501/III/1> <PICT:0798501/III/2> and 9 through which air, air charged with steam or smoke, or oxygen mixed with steam may be passed in a controlled manner from insufflation boxes 10a . . . 10n to provide uniform fluidization throughout the bed.  This air may, if desired, be introduced intermittently or in pulsations.  The upper part of the grate passes out of the furnace above the level of the bed, carrying clinkers and agglomerates with it and passing them to the ash bin 15.  If the gradient of the grating is more than 25 degrees projections or grooves are provided in the bars of the grating to prevent slipping of the agglomerate.  A sealing device in the form of a hinged flap 13 isolates the combustion chamber 14. Fig. 2 shows in section the same furnace, the upwardly flaring side walls of which have cooling tubes 2 supplied by headers 3 incorporated therein, and means 18 are provided for the supply of air to promote complete combustion if desired.  Other arrangements may be used, e.g. a horizontal conveyer followed by an inclined or vertical helical extractor, and it is stated that a screw-type conveyer may replace the grating provided it is possible to pass the fluidizing gas there-through.  If the walls of the reactor are spaced from the sides of the grating or if the walls are not too steep, banks of non-fluidized reactants are formed adjacent to the grating.  These banks could be cooled by the insertion therein of cooling surfaces parallel to the surface thereof.  A similar bank may be formed by reducing the pressure of the gas from the wind bores at the location at which the grating enters the furnace.

Abstract: 1,117,765. Sheet forming. ILLINOIS TOOL WORKS Inc. 12 July, 1965 [13 July, 1964], No. 29474/65. Heading B5A. In a plug-assisted vacuum moulding process, uniformity in the wall thickness of the article is ensured by initially sucking the sheet closely around the advancing plug. In the embodiment illustrated in Fig. 4 a heat softened sheet is clamped between a plug and a female die 80 and the plug forwarded to push the sheet into the die, movement being continued until a bellows like hood 60 surrounding the upper part of the plug contacts the sheet clamp 14, 16. The space within the hood is then evacuated and the plug further forwarded so that the sheet is drawn closely on to the plug (see Fig. 4), after which the sheet is transferred to the female die by connecting the hood to a compressed air source. The formed article is then severed from the rest of the sheet by further movement of the female die. In a second embodiment (see Figs. 6 and 7, not shown) the plug is of a paraboloidal shape to facilitate slipping of the sheet over its free end and has a passage extending therethrough to said free end, which passage is in connection via a non- return valve with the space within hood 47. During the initial drawing of the sheet, when the sheet closes the free end of the passage, the non-return valve is closed and the sheet, as before sucked on to the plug. The sheet is then transferred to the female die by introducing compressed air through the passage. In a third embodiment (see Figs. 10-13, not shown) the plug is made of a porous substance, e.g. sintered metal.
