Title: Improvements in apparatus for holding bobbins, or other analogous bodies holding or formed of yarn or thread to be unwound in creels or other supports in machines for winding, or winding and also doubling, or twisting or otherwise operating upon or usingyarns or threads
IPC: B65H67/02
Filed: 1931-11-20
Abstract: 386,087. Creel apparatus for spinning, winding, warping, or beaming machines, looms, &c. AMBLER, G. H., Chellow Grange, Bradford, Yorkshire, HOLT, H., Atlas Iron Works, Whitworth Road, Rochdale, and GREENWOOD, H., 25, Rawling Street, Ingrow, Keighley, Yorkshire. Nov. 20, 1931, Nos. 32176/31 and 26102/32. [Classes 120 (ii), 120 (iii), 142 (ii), and 142 (iv).] In creel apparatus wherein the yarn is unwound axially from bobbins x, Fig. 1, a support a for the pegs c<2> is mounted so as to be movable up into a position for the application of bobbins to the pegs and down into the unwinding position by being oscillated about a stud g the axis of which passes through or approximately through a guide p through which the yarn being unwound is guided. The support a may be oscillated through members a2, r by a treadle b. The member c carrying the pegs c<2> is rotatable on the support a and a catch d is pivoted on a bracket v so that when the support a is swung upwardly one arm c<1> of the member c engages therwith and the member c is turned through 120‹ on the support a. A curved inclined guide rail e is provided to dislodge the used bobbin. The last wound end of one bobbin is joined to the first wound end of another over a guide finger y. A conveyer f for used bobbins may be provided. The support a is held in the unwinding position by a detent spring l. When a bobbin x is completely unwound the treadle b is depressed and the support a swung upwardly in a clockwise direction the arm c<1> carrying the now emptied bobbin engaging the catch d and the holder c being thereby rotated through 120‹ the empty bobbin riding up along the rail e and being dislodged from the peg c<2>. A new bobbin is applied to the third peg c<2>, now brought to the front, and the ends led over the finger y. On releasing the treadle b the support a moves downwards into contact with the stop m, the holder c rocking the catch d about its pivot w. To minimize shock and to control the downward movement the support a may be mounted loosely on a shaft 4, Fig. 4, constantly revolving at a slow speed, a ratchet wheel 5 being secured thereto and adapted to be engaged by a pawl 6 on the rod r. During unwinding, or when the support a is raised, the ratchet wheel 5 slips past the pawl 6. When the support a moves downwardly the pawl 6 engages the wheel 5 and thus limits the speed of return to that of the shaft 4. Co-operating clutch members employing rollers or balls may be used alternatively. In a further modification, the support a is moved by a handle 10, Fig. 6, being locked in the unwinding or raised positions by the engagement of a spring detent 11 in notches 14, 15. The ratchet wheel and pawl 5, 6 may also be provided in this form of apparatus.

Abstract: 150,931. Huwyler, L. Dec. 23, 1919. Horse-boxes and cattle-trucks.-A skid or gangway 8 is normally housed under the floor 1 of a railway vehicle, but when drawn into the outboard or loading position, rollers on the rear ends are made to travel up an inclined slotted guideway 18, 19 so that the end of the skid attached to the vehicle is level with the floor. When the skid is in the inoperative position, it is locked by hooks 9 on a shaft 11 provided with an operating-handle. In moving the skid into the position for the loading and unloading operation, the front rollers 7 engage levers 28, 26 to operate a lever 21 pivoted at 22. The end 23 of the lever 22 is thus lowered and forms a guide for the rear rollers of the skid into the inclined slot 18 in the member 6. When these near rollers engage the cushioning-spring 30, the rear end of the skid is level with the floor 1, and it is secured in this position by the ends 39 of levers weighted at 40 and provided with arms. 45 against which abut locking- members 43 on a hand-operated shaft 44. To move the skid back to its position under the vehicle floor, the ends 39 of the weighted levers are first moved from the trackway 18, 19 by the operation of the shaft 44.

Abstract: 1362460 Fuel injection systems SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 11 July 1972 [21 July 1971] 32384/72 Addition to 1266803 Heading G1N In an I.C. engine intermittent fuel injection system having an auxiliary throttle member 3 situated in the intake manifold 1 and a rotary member 10 providing a release signal A to initiate injection on each revolution, as described in the parent Specification, two sawtooth signals B, C are provided, B being triggered by the release signal A and C being triggered when the amplitude of the two signals become equal, one of the signals having a slope dependent upon the position of the auxiliary throttle member 3, is upon the flow of air to the engine, injection being provided for the duration t of the sawtooth signal B. The system consists of a bistable circuit 14 triggered by the release signal A, the output of circuit 14 being applied to trigger a first sawtooth generator 15 which provides the signal B having a slope determined by the position of the auxiliary throttle 3 (potentiometer 4). A second sawtooth generator 17 provides the signal C of constant slope (or varying with engine temperature). Both generators include a capacitor which is charged to provide the sawtooth signal. The outputs of the two generators are applied to a comparator 16 which provides an output to cause the capacitors to discharge when the amplitude of the sawtooth signals B and C become equal. The bistable circuit 14 is also reset by the comparator output so that the pulse output of the bistable circuit 14 is applied to energize the injection valves. Circuitry is provided to prevent injection when the engine is decelerating and the main throttle 2 is in its idling position. An AND gate 35 is provided, one input being connected to the output of the circuit 14 and the other to the output of a second comparator 19 via a switch which is closed to inhibit the AND gate when the throttle 2 is in its idling position. The comparator 19 compares the sawtooth signal C with a preset reference so that the AND gate is enabled when the engine speed falls to its idling value. Details of the circuitry of the above described system are given in Fig.2 (not shown).

Filed: 1966-07-22
Abstract: 1,146,549. Film casting apparatus. EASTMAN KODAK CO. 22 July, 1966 [2 Aug., 1965], No. 33003/66. Heading B5B. In a process for casting a liquid composition into a thin sheet on coating a web or substrate the liquid composition is applied to a rotatable roll 15, from an extrusion die 10, the roll moving in the direction shown 16, and a pair of chambers, one of which 30, can form part of the extrusion die, and the other 35, can be part of a housing33, or both can be incorporated into the said housing, have openings which face the casting surface, the chambers being interconnected, and one of them 35, being connected to a vacuum source, said vacuum source serving to create a subatmospheric pressure on the side of the stream of the liquid that contacts the surface of the roll and so causing intimate contact between the liquid and the roll, thus enabling the roll speed to be increased without causing irregularities in the film produced. An adjustable baffle 47, regulates the amount of air which is drawn into the chambers, most of the air being drawn through the opening 36, of the chamber 35, to avoid vibration of the apparatus and consequent irregularities in the film. The pressure difference between the two sides of the liquid composition applied to the roll may range from 0À1 to 30À0 inches of water, the pressure on the side away from the roll surface normally being atmospheric. Thin films of polyolefins, polystyrene and polycarbonates may be produced and the invention is also applicable to the coating of a web of material which is moving past the point of application.

Title: Monolithic Ceramic Electrical Interconnecting Structure
IPC: H05K3/28
Filed: 1967-07-19
Abstract: 1,171,514. Printed circuits. DIELECTRIC SYSTEMS Inc. 19 July, 1967 [27 July, 1966], No. 33089/67. Heading H1R. A monolithic sintered ceramic laminate within which is encapsulated one or more circuit layers and interconnections, is formed by the steps indicated in Fig. 1. The electrically coductive layers are constituted by a two-phase metallic composition comprising a metal phase having a melting point below the sintering temperature of the ceramic, e.g. silver, gold, or copper (10-60% by volume), and the other metal phase is a refractory metal having a melting point substantially higher than the sintering temperature and having at least a slight solubility in the lower melting point metal. The ceramic may be formed from 50% or more of alumina, beryllia, magnesia, titania, zirconia, hafnia, silica, barium titanate, mullite, steatite or fosterite, mixed in a ball mill with plasticizer, synthetic resin binder and volatile solvent. The resultant slurry is cast into a sheet on a glass surface to which sheet further green ceramic sheets are laminated to the required thickness. Holes for interconnections are punched as required. The metallic composition in powder form is carried in suspension in a vehicle of volatile solvent to form an ink, which is applied to the green ceramic laminate by a silk screen process to form a required pattern, the interconnection holes at the same time being coated with the ink. A second sheet of green ceramic is laminated thereon under heat and/or pressure. Additional unfired ceramic sheets carrying circuit patterns and connection holes may be added before laminating under heat and pressure. The structure is then fired in steps up to a final value of 1600‹ C. approx. (Fig. 10, not shown) to sinter the ceramic and cause it to reach a gas impervious state. The sintering is preferably carried out in an inert or reducing atmosphere, e.g. argon or nitrogen, having about 10% hydrogen, to avoid oxidization of the metals. Examples are given of particular compositions of the ceramic and the metallic ink with details of the firing steps. The interstices between refractory metal grains retain the solidified liquid phase which forms another continuous network with very high electrical conductivity. Without the refractory component the other metal would not remain extended in the required conductor pattern at sintering temperature but would coalesce into disconnected droplets due to their high surface tension relative to the ceramic.
