Title: Knitting machine magnetic controlled yarn tensioner
IPC: D04B15/44
Filed: 1959-06-16
Abstract: 862,149. Knitting-machines. SCOTT & WILLIAMS Inc. June 16, 1959 [Jan. 23, 1958], No. 20572/59. Class 74 (2). A comb-tensioning device is employed in a circular machine using fine yarns under a light tension, and comprises three integral fingers 28, 28<SP>1</SP>, 28<SP>11</SP> pivotally mounted so as to be capable of moving the yarn 7 passing through guides 18 in the ends of the fingers into greater or lesser contact with knobs 20 extending between the fingers. The restraint imposed on the yarn is caused by the magnetic force between two opposed, like poles of two magnets 62, 70 repelling themselves apart, the one magnet 70 being secured to an adjustable bracket 64 and the other magnet being attached to one finger 28 so that the fingers are urged upwardly against the action of gravity and the pull on the yarn to cause the yarn to bear against the knobs 20. Prior to the yarn guide 6 of the machine being brought into operation a coupling 46, 54 connected to control bar 16 maintains the fingers in a high position and initially when the yarn guide is brought into operation the fingers are retained in that position by magnetic attraction between a fixed magnet 34 and a soft iron bar 30 on one of the fingers 28<SP>1</SP>. This ensures that the yarn tension is initially high and the yarn sufficiently taut that the yarn between the guide 6 and the yarn clamp 8 does not balloon up and bridge the needles without being taken, but is correctly taken by the needles whereupon the tension exerted is sufficient to overcome the effect of magnet 34 causing the fingers to drop to their normal working position where they come under the influence of magnets 62, 70.

Abstract: 662,508. Gear-wheel pumps. BORGWARNER CORPORATION. Aug. 9, 1949 [Sept. 7, 1948], No. 20682/49. Class 110(ii) [Also in Group XXIX] The supply of liquid to press sealing end plates B against gears 11, 12 is controlled by a manually-operated valve 23. The pump is unloaded by a small movement of the valve which allows pressure liquid to drain away from chambers MC, the valve also being used to hold outwards a motor piston M<SP>1</SP>, the cylinder of which has been supplied with liquid by the pump. Spring 58 hold the sealing plates in position for starting-up purposes. A third position of the valve allows liquid to flow away from the motor piston at a controlled rate whilst maintaining the sealing plates in the unloaded position. The motor may be used for actuating accessories on a motor tractor the engine of which would drive the pump through a gear 13. Liquid from a sump S is pumped through a pipe 14 past a non-return valve V<SP>1</SP> to the motor, part of the delivery flowing to a space 21. A port 18 connects the left-hand end of a cylinder 17 with the sump and in Fig. 1 releases liquid from the spaces MC by way of ducts 19a, 19. The motor piston is held by liquid behind it as an annular duct 21 is sealed by the valve 23. The liquid will be gradually released when the valve is moved to the right and a tapered 'surface 26 allows leakage through ducts 28, 29 to the sump. Stops 32, 33 act as limits to the travel of the motor piston relative to the valve 23 to relieve the pressure on the bushes B at the end of the motor stroke. Sealing rings 44 are provided. Gears 11, 12 are kept pressed against the faces of inner bushes B<SP>2</SP> by spring 55. In a simplified arrangement, Fig. 7 (not shown), a gear pump supplies a gear motor. The control valve is without the tapered surface. U.S.A. Specification 2,420,622 is referred to.

Abstract: 757,504. Gas turbine plant; jet propulsion plant. LUCAS (INDUSTRIES), Ltd., J. July' 21, 1954 [July 25, 1953], No. 20869/53. Class 110(3) [Also in Group XXIX] In apparatus for controlling the supply of liquid fuel to the combustion chamber of a jet-propulsion engine or a gas turbine the blower air pressure acts on a pair of elastic bellows-like capsules f, i one of which (f) is responsive to variations of blower air pressure in the 'upper part of the pressure range and the other of which (i) is responsive to the pressure variations in the lower part of the range. The capsules which are evacuated are arranged coaxially in compartments b, c and connected by a stem j passing through a seal k. The outer end of the capsule i is anchored in the compartment c and the outer end of the capsule f is connected by a lever h to the control of a liquid-operated servo mechanism. The capsule f is pre-stressed by a yoke g which embraces it and so responds only to pressures above a predetermined value. Blower delivery pressure is admitted to the compartment b through a port e. The compartments b, c are connected through a further compartment d containing a third evacuated capsule m which is responsive to the higher blowerair pressures and at a predetermined pressure closes a normally-open valve n to cut off the compartment c from the compartment b. The lever h then responds to movement of the capsule f only, the compartment c then being vented to atmospheric through a restricted orifice o and the expansion of the capsule i then being limited by the wall between the compartments b, c. In a modification the capsules i, f are arranged with their axes parallel and are connected by a lever p, Fig. 3, with a sealed pivot q between the compartments b, c. This arrangement is shown in Fig. 3 applied to the control of a throttle, member x controlling an orifice y in the fuel supply line between a pump z and the burners. The lever h carries a leak-off valve s controlling a 'servo-piston v formed on or secured to the throttle x. The throttle opening is thus controlled according to blower delivery pressure. The pressure drop across the throttle x is applied to opposite 'sides of a spring-loaded diaphragm 6 which operates through a lever 8 a servo-vent valve 9 controlling a spring- loaded servo-piston 12 adapted to control the output of the pump z.

Abstract: 149,209. Huth Ges., Dr., E. F. Dec. 15, 1917, [Convention date]. No Patent granted (Sealing fee not paid). Wireless signalling; thermionic detectors and relays; electric oscillations, producing.-In a combined transmitting and receiving apparatus employing thermionic valves, the coupling of the antenna with the output circuit of the valve is adjusted for optimum transmission by a device which simultaneously varies the tuning of the antenna. The same adjustments, being sufficiently near to the optimum adjustments for receiving, are used for that purpose. The coupling and tuning of the antenna 101 are simultaneously adjusted by means of the switch 108 which may be positively connected to the switch 109 in the grid circuit. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement of thermionic valves for heterodyne receiving, which can readily be converted for transmitting either simple or musically modulated radiation. The two valves 1, 22, Fig. (Cancelled), are cross coupled, the plate 2 being shown as coupled at 11 to grid 26, and plate 46 as coupled at 20 to grid 3. Plate 2 is also coupled to the aerial. In receiving the locally generated oscillations beat with those received from the aerial, and the beats are communicated through the primary coil 10 and amplifying valves 22, 32, to telephone 35. For transmitting undamped waves, interruption or shortcircuit is effected at points 37. The waves may be modulated by periodically varying the parts 18, 19, 20, in which case the interruption is made at one or both points 36. For wireless telephony a microphone circuit is introduced at 36. The filament currents of the three valves 1, 22, 32, are tapped off the same resistance 15 in circuit with battery 14, iron resistances 29, 34, being in series with filaments 28, 33. All three plates are charged by a high tension battery 8 which is tapped by a switch 13. The aerial coupling is adjusted for optimum transmission, and the same coupling is used for receiving. The switches effecting the change-over from reception to transmission and vice-versa are coupled so as to be operated by a single movement. This subjectmatter does not appear in the Specification as accepted.
