Filed: 1946-04-29
Abstract: 617,183. Valves, PLOEG, J. RATELBAND-. April 29, 1946, No. 12788. Convention date, Oct. 25, 1945. [Class 135] A valve device comprises a casing 1, an inserted tubular member 2 which is gradually reduced in diameter from its opposite ends towards a central partition 3 and a flexible sleeve-like member 6 surrounding the tubular member and adapted to control openings 4, 5 on opposite sides of the partition under the control of fluid pressure or vacuum applied to a chamber 11. The pressure fluid may be water or air and may be supplied by a compressor or a vacuum plant or hydrostatically. The pressure fluid may be controlled from a remote point or as in Fig. 2, by a cock 14 with an angular passage 16, whereby the chamber 11 may be placed selectively in communication with the inlet or outlet sides of the valve. The ends of the sleeve 6 have inwardly directed flanges held by clamping rings 15, 15<1>. The sleeve 6 may have a central collar connected to the inside of the casing and resisting contraction of the sleeve on to the tubular member. In a modification, the members 2 and 6 extend the full length of the casing and the member 6 has flanges which act as packings. The Specification as open to inspection under Sect. 91 comprises a tap, Fig. 3 (Cancelled), having a tubular member 2 screwed into the tap body 1 and a chamber 11 sealed by a packing 19. Inlet pressure has access to the chamber 11 through a port 20 and a passage 21 larger than the port 20 communicates with the outlet 24 through a cock 22. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in and relating to electric regulating systems
IPC: H02P9/14
Filed: 1924-05-24
Abstract: 216,871. British Thomson-Houston Co., Ltd., (Assignees of Thompson, L. W.). May 28, 1923, [Convention date]. Regulation, automatic.-For maintaining constant or defined speed or voltage of an electrical machine, a commutator driven at the desired speed co-operates with a similar commutator driven by the machine to be controlled in such a manner that any relative advance or retardation varies the field strength of the controlled machine in a compensatory sense. In the constant speed arrangement shown in Fig. 1, a synchronous motor 10 imparts the standard speed to a two-part commutator 9<1> and a controlled motor 2, running under load, drives a similar two-part commutator 8<1>. The commutators are connected in parallel with each other and in shunt with a resistance 5 which is in circuit with the field winding 4 of the motor 2, the effect being that any lag or lead of the commutator 8<1> varies the time during which the resistance is short-circuited and thus compensates the field strength in the required direction. At the limits of regulation, driving pegs attached to the commutators interengage in order to prevent an inverse action of the apparatus. In voltage regulation of a generator the controlled resistance is in circuit with the generator field and the motor 2 is replaced by a series alternating current motor fed by the generator.

Title: Improvements in or relating to liquid control systems
IPC: D06F39/08
Filed: 1945-05-28
Abstract: 618,414. Valves. DOLE VALVE CO. May 28, 1945, No. 13317. Convention date, April 24, 1944. [Class 135] A liquid control system, applicable to a washing machine, comprises a liquid supply duct, 17 or 18, containing a valve 11 or 12, a metering device 13 for measuring the quantity of liquid flowing through the duct, a continuously running substantially constant speed cycling means, e.g. the timer motor 29 driving the cams 30, 32, 33 for actuating the valve electromagnetically at preselected times by means of an electrical circuit connected at 27, 28, to a power supply, and means independent of the cycling means and operated by the metering device, e.g. the cam 26 acting on the latch arm 60, for closing the valve. Hot and cold water from the pipes 15, 16, respectively, enter a dual mixer valve 10 from which the water may flow at one temperature through the duct 17 and at another temperature through the duct 18. The cam switch 41 closes the switch 54 by means of the electromagnetic relay 53 before the closing of either of the cam switches 39, 40, thus partly completing the circuit 31, 51, 59, 54, 27 for the actuation of the valves 11, 12. When one or both of the switches 39, 40 are closed, one or both of the valves 11, 12 is opened and the flow of water through the metering device to the tub 14 rotates the cam 26. Before the closing of the valves 11, 12, the cam switch 41 is opened to de-energize the relay 53, but the switch 54 is kept closed by means of the spring-loaded latch 64 as shown by the dotted lines 61. When a predetermined quantity of water has flowed through the metering device, the cam 26 lifts the latch 64 and the switch 54 is opened by the spring 55 to break the electrical circuit for both valves so that the valves, if open, will close. The metering device 13 is of the type in which liquid flow turns cup-shaped blades keyed to a shaft which rotates the cam 26 through reduction gearing. Specification 626,607 is referred to.

Title: Circular knitting machines
IPC: D04B9/34
Filed: 1974-03-26
Abstract: 1470182 Knitting machines; knitted pile fabrics BUNKER RAMO CORP 26 March 1974 [8 May 1973] 13359/74 Headings D1C and D1K [Also in Divisions F2 and G3] A circular knitting machine for producing pile fabrics comprises means such as a doffer roll 22a, b for feeding pile fibres to spaced delivery zones wherefrom the fibres are picked up by selected ones of the needles 6 in accordance with the desired pattern and are transferred to the knitted fabric and controllable means adjustable while the machine is operating for regulating the quantity of fibres delivered by the selected needles to the fabric, which means provide a control independent of the rate of supply of fibres to the feeding means of the machine. The machine shown in Fig. 4 is a modification of the machine disclosed in Specification 1350966 and the controllable means are embodied by adjustable lifting cams 50 which are lowered or pivoted by eccentrics 50b and solenoids 50e, ee to reduce the maximum degree of penetration of the needle hooks 6a into the doffer clothing. Alternatively (Figs. 4A and B, not shown) the same effect may be produced by providing adjustable cams at the top of cam tracks 44a, 44c for needle butts 6b. Instead of adjusting the extent of needle reciprocation the doffer roll may itself be adjusted relative to the needles by means of an eccentric mounting (Fig. 3, not shown). Further the quantity of fibres fed to the doffer roll may be varied by adjustable mounting thereof or of an intermediate transfer roll (Figs. 12 to 14, not shown). In an alternative embodiment (Figs. 9 and 10, not shown) the angle of penetration of the needles into the doffer clothing may be altered by means of a cam which engages the needles adjacent their hooks to deflect the needles. In a further embodiment (Figs. 19 and 20, not shown) the quantity of fibres carried by each needle may be reduced after pick-up by means of air nozzles. In yet another embodiment (Figs. 17 and 18 not shown) each trick carries two needles with different sizes of hook openings and the amount of fibre brought through each loop of body yarn is varied according to which needle of the associated pair is raised. In the Fig. 15 embodiment the size of the hook opening is controlled by a sliding latch 173 equipped with a butt 177 which is engageable in alternative cam tracks 180, 183 or 187, 188 according to the energisation of control electromagnets 181, 182, 184, 185 and 189. In the Fig. 21 embodiment sliding latch needles are controlled by spring-loaded jacks 231 actuated in turn by spring rods 233 which are directed by cams and magnets into the appropriate one of three cam tracks 250, 253, 254 wherein the needles are not lifted, the needles are lifted by a cam 238 with their hooks fully open, and the needles are lifted with their hooks partially closed for an adjustable interval of time, respectively. The various controllable means of the different embodiments are suitably controlled by electronic circuitry which reads a magnetic or optical tape, and manual programming is provided for.
