Title: Improvements in yarn control means
IPC: B65H63/06
Filed: 1932-06-27
Abstract: 392,759. Tension and stop apparatus for yarns. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Sipp-Eastwood Corporation ; 45, Keen Street, Paterson, New Jersey, U.S.A.) June 27, 1932, No. 18171. [Classes 120 (ii) and 142 (iv).] A yarn tension mechanism comprises a revoluble pulley with which the yarn is in tractive engagement, and which is the last. means of applying tension before the yarn passes to the means which exerts draft, together with additional tension means, preceding the pulley, such that the tension exerted by the preliminary means is less than that exerted by the pulley. The yarn A is led, for example to form a warp in warping, between the freely mounted frusto-conical discs 17 and round the pulley 12, which is rotatably mounted on the axle 4 between two felt washers 11, 13, held between a counterweight 10 and a disc 14 weighted at 15. The counterweight 10 causes the vertical axle 4, which is pivoted in the depending arm 3b, to tend to swing away from the direction of the yarn tension, whereby upon yarn breakage it swings over until it contacts with a contact on the electric lamp 9, which is thereby illuminated, and a stop-motion circuit completed. A modified form of pulley with which only a partial turn of the yarn round the pulley is necessary, and hence suitable for yarns having projecting fibres, comprises two discs spaced apart and having radial corrugations arranged so that the yarn passing between them is caused to take a sinuous path.

Abstract: 744,299. Endless conveyers. MORGAN, C.F. July 17, 1953 [July 21, 1952], No. 18323/52. Class 78 (1). [Also in Group XVII] Apparatus for treating the interior of casks and like containers by injecting a gas or fluid into the bung hole for drying, cooling, washing or sterilizing the containers comprises an endless conveyer having cradles spaced apart longitudinally along it to receive the containers, means for feeding the containers in succession to the cradles, a box situated under the conveyer and having a slot extending along its upper surface, an endless belt in said box having holes spaced along it which register with the slot and with the bung holes of the containers on the cradles, said belt otherwise forming a closure for the slot, means for driving the belt and conveyer in unison, and means for supplying gas or fluid under pressure to said box. As shown, casks to be dried and cooled after being washed are fed by a reciprocating carriage 39 on to cradles formed by aligned parts 11 on endless chains 13, 14, these parts 11 sliding on framework parts 24, 25 so as to relieve the chains of the weight of the casks. Air under pressure is supplied to a box in the framework 10 constituted by end closures, side walls 27, a bottom 28, and a top 29 formed with a slot 30. This slot is closed by rubber pads 34 mounted on the links 31 of an endless chain 31a, these links being provided with skid plates 32 running on guides 33. Each pad located beneath a cradle is formed with a hole 35, and the bung hole 36 of the cask on the cradle is arranged over the hole so that air may be admitted into the cask from whence it passes out through the top hole 37. This chain 31a is driven by a sprocket 38 on a shaft 23 driven from the conveyer driving shaft 17. The casks are placed on rollers 40, 44 on the carriage and rolled on these so as to bring the bung hole to the bottom. The carriage is moved along the tracks 46, 47, 49 between a receiving station as shown in Fig. 1 to a delivery station adjacent the end of the conveyer by an arm 50 on a shaft 51 carrying the adjacent terminal sprockets supporting the chains 13, 14. This arm engages a roller 52 on the carriage frame member 43 so as to move the carriage to the downwardly sloping part of the tracks down which it falls and deposits the cask on a cradle. The carriage is returned back along its tracks by the arm 50 which, after it has moved clear of the roller 52, engages the arm 57 of a bell crank lever 56 and through links 55, 54 actuates a link 53 connected to the carriage.

Title: Improvements in or relating to hydraulically actuated flexible chamber pumps
IPC: F04B43/113
Filed: 1965-04-30
Abstract: 1,072,378. Flexible chamber pumps. DE LAVAL TURBINE Inc. April 30, 1965 [Nov. 6, 1964], No. 18401/65. Heading F1A. In a diaphragm pump having a bellows 36 expanded by liquid under pressure supplied through port 18 and contracted by a piston 70, secured to the bellows by means of rod 44, liquid under pressure is fed to the bellows when it approaches the fully contracted condition. In the embodiment illustrated, a flange 98 on rod 44 lifts an annular valve member 96 to open passages 90 in communication with the liquid pressure source. In another embodiment, a distributing valve (148), Fig. 4 (not shown), controls the main and auxiliary supplies of liquid under pressure to a pair of bellows pumps. The valve (148) comprises a housing (150) and a motor reciprocated spool (158) and controls the supply of liquid under pressure from an inlet (152) to a pair of outlets (180, 182). When the bellows of the pumps approach their contracted and fully expanded positions the outlets (180 and 182) are connected to the inlet (152) via annular spool grooves (210, 212) and restricted spool passages (214, 215). A system for operating a pair of pumps to give a substantially constant output at a substantially constant pressure, Fig. 1 (not shown), comprises a screw type pump (2) driven by a variable speed motor which may be adjusted to vary the supply to a distributing valve (8). The valve (8) is connected to the pair of pumps (14, 16) and bellows contracting cylinders (74) are connected to one another in order that downward movement of one bellows contracting piston causes the other piston to contract the respective bellows. An accumulator (124) and a pump (P), operated by a motor M at a predetermined pressure in the line connecting the bellows contracting cylinders (74), are connected in the line to maintain the line pressure. The liquid to be fed to the bellows as they approach their fully contracted positions is supplied by the screw type pump (2) via a relief valve (138).

Title: Apparatus for heat-treating metals employing a carbonizing atmosphere
IPC: C21D1/76
Filed: 1964-05-04
Abstract: Apparatus for gas carburizing metal workpieces consists of a furnace chamber (which may be resistance heated) having a fan for internal circulation, means including a compressor and filters &c., for externally recirculating the furnace atmosphere and means for introducing controlled amounts of carburizing agent into the gas stream on the inlet side of the compressor.  As particularly described, when the furnace chamber (11) (Fig. 1) reaches its operating temperature as determined by a thermocouple (17), a switch (20) is closed whereby a relay (26) is energized, thus activating a compressor (25) which discharges through a catalytic atmosphere generator (52) a mixture of carburizing agent such as natural gas entering through an inlet valve (35) and a throttle valve (41) and air entering through a second inlet valve (46). This continues for a period determined by a timer (55) and such that equilibrium conditions are obtained in the furnace, and its antechamber (12) the effluent gases being burnt during this period.  The work is then transferred to the furnace and the flow of gas continued under the control of the timer until equilibrium is regained.  Until this stage is reached the supply of carburizing agent is interrupted by intermittently closing the inlet valve (35) by means of a cam operated switch (57, 58) in the valve control circuit, whereby any deposits of carbon on the catalyst are removed. The relay is then de-energized, with the result that control of the incoming carburizing agent passes to a second throttle valve (62), and a two way valve (36) is operated so that the compressor no longer takes in air but recirculates the furnace atmosphere which it now discharges directly into the furnace. This circulation continues until the carbon potential of the furnace reaches a desired level as measured by a suitable detector element (70), which means of a suitable circuit causes the carburizing agent inlet valve (35) to be operated to maintain the carburizing potential at the desired level.  The atmosphere generator (52) consists of a tube (80) of suitable refractory material projecting into the furnace and having at its inner end a spirally wound roll of nickel wire (53) which may be surrounded on its cylindrical surface by a thermally insulating layer of woven ceramic fibre.

Class 98 (2). An endless conveyer band passes loopwise into and out of a plurality of consecutive treatment baths, the band being assembled from wires each formed with bent-over ends to engage the adjacent wire and form a chain, print holding means or clips being attached to the wires, particularly to loops provided therein. As shown, Fig. 1, prints from table 26 are attached by clips 6 to band 1 to be carried through bath tanks I to V and released at delivery tray 37, after which the band goes down past tank V and through a drying tunnel 21 back to the position of 26, the band being driven by motor 20 from transport rollers 15 at the top of the tanks. Band 1, Fig. 3, has wires 2 with bent engaging ends 3, the wires having angled loops 4 with cranked portions 5 carrying spring clips 6 which latter, Fig. 5, have each an extension 29 of an upper jaw containing slot 30 through which passes a lug 31 formed in the lower jaw 6<SP>1</SP>, which lugs form smaller spring clips 33 terminating in holder members 35 with serrations 34. The extension 29 and serrations 34, shown in open position, are closed by spring action upon a print on pushing the latter between them to move clamping lever 28 to the left. Reverse movement of lever 28 opens the jaws to permit release of the print and such may be effected automatically by action of the lever 28 against striker plate 27, Fig. 1, to deposit the processed print on delivery tray 37.

Title: Resilient bushing
IPC: F16D3/28
Filed: 1951-08-07
Abstract: 699,933. Universal joints. GUY, F. M., and SAURER, C. Aug. 7, 1951 [May 7, 1951], No. 18602/51. Class 80 (ii). [Also in Group XXXII] A method of manufacturing a resilient bushing comprises the steps of rolling a torus-shaped resilient element 28 (Fig. 3) on to a central member 30 into an " inverted " position in which the outer surface of the torus becomes the inner surface adjacent the central member, and the inner surface becomes the outer surface, and placing an outer shell 22 over the element. The rings 28 are assembled on the member 30 as shown in Fig. 5 with the aid of tools 36 and 53, the outer profile of which is formed to be continuous with that of the member 30 which is formed with respective grooves 32 for each ring 28. During this process the rings are " inverted " so that points 1, 2, 3 take up the position 1', 2', 3<SP>1</SP>. As applied to a shaft coupling (Fig. 3) each coupling element 10 carries a pair of members 30 and each corresponding shell 22 is formed by a pair of stampings 24, 26 which are common to all four bushings of the coupling. In another construction, Figs. 6, 7 (not shown), the outer shell 22 is in the form of a cylindrical sleeve which is held in a flanged socket. Adhesive may be used in order to maintain the ring in the " inverted "position on the member 30 during assembly of the outer shell 22. In the construction shown in Fig. 9, the outer sleeve 22 is formed in two portions 24, 26 and provides a dovetailed groove 63a. The inner rigid member 30 is also formed in two portions 66, 68, in such a way as to provide a groove 70a in radial alignment with the groove 63a. A single rubber ring 28 has the form shown in Fig. 10 before assembly and has inner and outer radial proprojections 72a and 64a respectively. The ring is assembled between the members 22 and 30 with the outer projection 64a located in the inner groove 70a and the inner projection 72a located in the outer groove 63a. In a modified construction, Fig. 11 (not shown), the grooves and projections are not dovetailed and the member 30 is of one-piece construction. In a further modification, Fig. 12 (not shown), the projection 72a is dispensed with, and on assembly, radial pressure on the ring 28 forces rubber into the outer groove 63a which is smaller than the corresponding groove of Figs 9 and 11. In another construction, Fig. 13 (not shown), provision is made for a plurality of rings 28 disposed between respective pairs of grooves in the inner and outer members.
