Title: Improvements in fluid control valves
IPC: F16K31/122
Filed: 1964-08-04
Abstract: 1,047,810. Valves. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Aug. 4, 1964 [July 17, 1963], No. 30566/64. Heading F2V. A valve comprises a body 10 having an inlet 11, outlet 12 and a seat 13 which coacts with a closure member 17 slidable with clearance in a guide member 18 and formed at its upper end with a seat 17B for a pilot valve 26. The pilot valve is connected by rod 27 to a piston 29 working in a cylinder 28, which cylinder is connected by rod 39 to a piston 42 working in a cylinder 40 and by tube 35 and yoke 36 to the closure member 17. When the valve is closed, fluid from the inlet 1 occupies chamber 25 and urges the main closure member and the pilot valve to their closed positions. To open the main valve, piston 29 is raised by admitting fluid at 33 and then piston 42 is raised by admitting fluid at 40B. When closing the main valve with the pilot valve already closed, the speed of closure is dependent on the leakage to chamber 25 from the inlet. In an alternative embodiment (Fig. 2, not shown), the main closure is connected by a rod to pistons corresponding to pistons 29, 42, and the pilot valve is connected by a tube surrounding said rod to a cylinder corresponding to cylinder 28. Members 13 and 18 may be replaced by a single sleeve having a series of axially spaced rings of holes adapted to be progressively obturated by member 17. Instead of pistons 29, 42, the valves may be actuated by hand wheels or electric motors.

Title: Improvements relating to automatic display apparatus, particularly applicable to articles of clothing and the like
IPC: A47F3/08
Filed: 1929-10-11
Abstract: 341,101. Moving display apparatus. KOLL E R, R., 33, Badstrasse, Baden, Switzerland. Oct. 11, 1929, No. 30956. Convention date, May 28. [Class 3(i).] Articles of clothing &c. are suspended in rows from two parallel endless chains c, c<5> arranged in vertical planes and intermittently moved in opposite directions. A horizontally oscillating lever F transfers the articles in turn from the front of one chain c to the front of the other c<5>, and they are circulated rom the rear of the chain c<5> to the rear of chain c along a rail s. The members c, F, and c<5> are disposed at descending levels. The articles are suspended by hooks y which take over notches in the links of the chains c, c<5>, and are carried by a hook t<1> on the lever F. The lever F is oscillated by gearing from a motor m from the position P<1> to the position P<5> with an intermediate stop at P<3>. The hook t<1> is rotatable relatively to the lever F by chain and pinion gearing k, k<1>, k<2>, the rotation being such that the article presents the same side outwardly during the turning of the lever F, and during its stop at P<3> makes one or more complete turns through the wheel k being put by a clutch controlled by a stop z<5> into engagement with a uniformly rotating wheel v<3>. The hook t<1> is pivoted at t<2> to the shank t, and is turned down to deposit the article on the chain c<5> when a lever t<4> is allowed to tilt by the knocking away of a retaining pawl t<5> by a stop z<10>. A roller t<6> on the lever t<4> strikes a stop z<4> to restore the lever t<4> into engagement with the pawl t<5>. The intermittent rotation of the chains c, c<5> is effected by a lug f<9> on the lever F which collides with spring- controlled pivoted levers z<2>, z<7> co-operating with rocking levers p, z<8> which through rods g<7> actuate clutches coupling the driving shafts b<5>, m<7> to the chain sprockets g for the requisite length of time. The articles are transferred from the chain c<5> to the chain c by a lever u universally pivoted at u<7> and oscillated by a cord q. The upper end x<6> of the lever u engages a slot s<1> in the rail s. A hook x<2> is pivoted to a lever extension x to turn up to receive the articles from the chain c<5> or down to deposit them on the chain c by sliding and pivoted elements x<3>, x<4>, u<3> which are controlled by a cam u<1>. The extension x is pivoted about a spindle x<1> and is maintained vertical for all positions of the lever u by a counterweight u<4>. The cord q is attached at one end to the end x<6> and has its other end wound round a drum d which is intermittently rotated in one direction by the engagement of a clutch d<5> with a uniformly rotating shaft n, the clutch being controlled by the lever F. During the non-engagement periods the drum d and cord q are retracted by a spring or weight on the lever u. Specification 336,101, [Class 3 (i), Advertising and displaying apparatus, Moving &c.], is referred to.
Patent GB-964382-A (GB)
Title: Apparatus for continuously producing curled yarns
IPC: D02G1/00
Filed: 1962-08-13
Abstract: 964, 382. Curling yarns SOC. RHOVYL. Aug. 13, 1962 [Aug. 18, 1961], No. 30964/62. Heading D1F. Apparatus for curling yarns comprises a core 2 for winding the yarn thereon, a sleeve 1 surrounding the core at a point upstream of the winding point, means for producing relative axial reciprocation between the core and the sleeve to move the convolutions of yarn along the core and means for setting the yarn in its coiled form. In one embodiment the yarn passes from a rotating bobbin through passages in a member 12, in a shaft 6, and on a combined shaft 7 whorl 5 and whorl extension 30, to be wound on the core 2. Preferably the sleeve has longitudinal teeth fitting into corresponding grooves in the core to prevent the yarn convolutions moving back into the sleeve with the core. The core is linked by a non- rotatable member 4 and shaft 6 to the member 12 which is reciprocated by a pin 20 moving in an eccentric groove in a wheel 8. The end of the extension 16 of the core 2 may be turned over to provide an eccentric weight to overcome the slight friction by the bearings 24 on the sleeve 1 and thus prevent the core-and sleeve rotating. The shaft 6 rotates with the whorl 5. Guide rails, Fig. 3 (not shown) may be provided in the oven 14 to space the yarn away from the core extension 16. In another embodiment, Fig. 6 (not shown) the core and sleeve may rotate with the whorl 5, with the yarn passing direct from the bobbin to be wound on the core. The core may alternatively be reciprocated by any electromechanical, electromagnetic or mechanical devices with perhaps one reciprocating device coupled to two curling heads.

Filed: 1966-07-11
Abstract: 1,113,140. Transistor switching circuits. RADIO CORPORATION OF AMERICA. 11 July, 1966, No. 31048/66. Heading H3T. [Also in Division G4] In a switching circuit having two crosscoupled current-controlling devices 10, 20, the switching time is reduced by connecting a further current-controlling device 50, 70 across the load impedance 18, 28 of each of the devices 10, 20, the circuit also includes a further two current-controlling devices 60, 80 connected across each of the devices 10, 20. The circuit shown uses insulated gate field effect transistors and has a transistor 60, 80 connected across each of the transistors 10, 20 such that when the set input 104 goes negative to turn OFF input transistor 100, transistors 50 and 80 are turned ON ; this allows the interelectrode capacitances and stray capacitances 114, 112 across the transistors 10 and 20 to be rapidly charged and discharged so as to rapidly turn ON transistor 20 and OFF transistor 10. When reset pulses 88 are applied at 94 the transistors 60, 70 conduct and the bi-stable pair 10, 20 change state, transistor 10 becoming ON and transistor 20 becoming OFF. By connecting two series-connected transistors (120, 140) and (130, 150) (Fig. 2, not shown), in series between the transistors 50, 60 and 70, 80 a two-phase shift register may be formed having odd-numbered stages for main storage and even-numbered stages for interim storage. Shift pulses (166) are then required in addition to the set or reset pulses obtained from the output of a preceding stage to change the state of the circuit. Transistors of the opposite conductivity type to that shown may be used and the circuits can be made in integrated form.

Abstract: 826,497. Rectifying; transformers. GENERAL ELECTRIC CO. Ltd. Oct. 11, 1957 [Oct. 11, 1956], No. 31064/56. Class 38 (2). A D.C. traction motor 10 is energized from a transformer 6 through mercury arc converters 9a-9h having anodes connected to different tappings on the transformer secondary winding 7 and cathode connected to one terminal of the motor armature, the other terminal being connected to the central point of winding 7. The converters which may be of the kind described in Specification 817,504, [Group XL (a)] are controlled by exciting electrodes which may be rendered positive from rectifier 19 upon closure of switches 17. Two switches 17 associated with converters spaced equally from the centre tap are normally closed so that the motor receives fully rectified current. To vary the motor voltage, switches 17 of two converters next to the two conducting converters are closed to render them conducting, and the switches 17 of the conducting converters are opened to render them now conducting. All the excitation circuits are opened on overload by relay 20. The motor 10 has two field windings 14, 15 and a filter circuit comprising inductor 12 and capacitor 13. In another arrangement, two pairs of exciter controlled converters acting as diverter switches are connected to the transformer tappings through selector switches. Pairs of converters normally conduct in parallel, but to change the motor voltage first one and then the other converter of a pair is connected to the next tap. Their conductivity is appropriately controlled by switches in the exciter circuits which operate with the selector switches. Load shaping is assisted by chokes (Fig. 3, not shown). In a modification the respective converters of a pair are connected to one of two tapped secondary windings (Fig. 2, not shown). The rectifiers may be arranged as a bridge. Specifications 817,301 and 817,505, [both in Group XL (a)], also are referred to.
