A pressure regulator wherein a main valve 15, Fig. 2, is controlled by pressure of the fluid at the valve outlet 13 or at a remote point to which fluid is fed from the outlet has an isolating valve 33 effective to prevent the diaphragm 18 piston or like element from acting under the influence of the pressure of the fluid at the outlet or the remote point, until a predetermined pressure is reached in the latter fluid, whereupon the isolating valve is opened so as to render the diaphragm, piston or like element operative. The input connection 24 of the valve 33 is connected either to the regulator outlet 13 or to a remote piece of apparatus such as an autoclave or sterilizer fed by the regulator while the outlet 27 is connected to the diaphragm chamber 17 which has an adjustable needle valve 41 to bleed it to atmosphere and to determine the pressure at which the main valve starts to close. The valve 33 consists of a stainless steel or plastic ball mounted on an adjustably spring-loaded phosphor bronze diaphragm 30. A sealing bush 14a of p.t.f.e. is provided on the spindle of the main valve. In Fig. 4, the main valve 55 is held open by inlet pressure acting through passages 77, 80 a filter 79 and a pilot valve 72 on a piston 58 until an increase in outlet pressure or in the pressure at a remote point acts through an isolating valve similar to that of Fig. 2 on a diaphragm 68 to allow the pilot valve to be closed by a spring 75. The isolating valve and an adjustable needle valve are connected to the diaphragm chamber 65 by a common connection 83 while the diaphragm 68 is connected to the pilot valve 72 by a push-rod 62 having a gland 62a. A space 60 forming the diaphragm chamber when the pressure regulator is used in the ordinary way is connected by passages 81, 82 with the valve outlet. The diaphragms in both constructions may be replaced by pistons and the isolating valve incorporated in the main valve body. Specification 789,300 is referred to.

Title: Improvements in synchronous repeaters for telegraph systems
Inventor: GREEN NORMAN GEORGE
IPC: H04L7/033
Filed: 1960-11-08
Abstract: 977,221. Automatic phase control systems; telegraphy. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Nov. 6, 1961 [Nov. 8, 1960], No. 38372/60. Headings H3A and H4P. A telegraph pulse synchronous repeater comprises a low-frequency pulse generator retroactively controlled in frequency and phase in accordance with the incoming signals. The pulse generator may comprise a sinewave oscillator 4 with bridged-T R-C filter in the feedback path between two transistors, together with a single transistor squarer 3 feeding a division by two transistor bi-stable circuit 2 which changes over at intervals equal to one half the duration of an incoming signal pulse. The two outputs from the latter may be applied to the bases of a pair of transistors with emitters both series connected to a further transistor to which short pulses are applied derived from the transitions of the input signal bi-stable circuit 1, so forming a phase gate 7 with pulse outputs either to an early pulse shaper 8 or a late pulse shaper 9 depending on whether the oscillator 4 is ahead or late in phase. The outputs of opposite polarity of 8, 9 (both transistor monostable circuits) may be applied to opposite ends of a potentiometer with tapping connected to a smoothing capacitor whose output through a transistor amplifier is applied to both the bases of oscillator 4 correcting any frequency or phase drift. As shown, the frequency divider 2 controls an amplifying gate 6 (similar to gate 7) to produce samples of the output of bi-stable circuit 1, nominally at the middle of each mark or space, which are applied to a further bistable circuit 11 whose output energizes a polarized relay 12 to transmit marks or spaces to the line L2. The output pulse edges of divider 2 may also through monostable delay circuits 13, 14 render temporarily conducting one of two series connected transistors forming a coincidence gate 15 only opened when short pulses from the input circuit 1 are applied to the other transistor, i.e. during distortion of the incoming signal. The gate 15 output then through a monostable pulse generator 16, an integrating capacitor and amplifier 17, if those conditions persist, energizes an alarm circuit 18 and at the same time acts on the output bistable circuit 11, by earthing one of the transistor bases, so that a continuous mark signal is supplied to the line L2. Specifications 823,874 and 897,392 are referred to.

Abstract: 1,073,440. Steam irons. HOOVER Ltd. Sept. 8, 1965 [Sept. 17, 1964], No. 38390/65. Heading DIA. [Also in Division Fl] A flash boiler type steam iron having a spraying device with a manually operated pump has a single control member to operate the valve connecting the reservoir to the flash boiler and the pump. The valve comprises a vertical rod 8 and a valve body 6 mounted in the base of reservoir 5 which is filled through opening 17 when the iron is up-ended. Rod 8 is biassed upwardly to hold the valve open by a coil spring 19 engaging a projection 18 on rod 8 and a side extension of a casting 9 carrying a spray nozzle 16. Nozzle 16 is connected by passage 15 to the pump cylinder 12 in which slides piston 14 biassed upwardly by spring 13. Cylinder 12 is connected through a ball valve 11 and bore 10 with the lower part of reservoir 5. The control member 25 has a flat portion with a slot (30), a groove 31, a convex portion 26 which engages recesses 20, 21 in the handle and a rear portion undercut at (29A) to engage portion 24 of the handle. A leaf spring 33 which engages piston 14 and rod 8 co-operates with slot 30. Thus, when member 25 is placed with portion 26 engaging recess 20, rod 8 is held down to close the valve and the pump is not operable so that the iron operates as a dry iron. When portion 26 engages recess 21, rod 8 is released and portion (29A) is disengaged from portion 24 so that steam is produced and the pump may be operated. In modifications portion 24 may be omitted so that either spraying can take place in both positions or a projection (42) may be provided on the handle engaging a slot (41), Fig. 4 (not shown) in the control member to prevent pumping during steaming. The member 25 may be supported by a spring steel bracket (43) Fig. 7 (not shown). A modified control member (51) Fig. 9 (not shown) operates directly on piston (78) and carries a spring (67) which engages the valve rod (72).

Abstract: 1,046,489. Cigarette-making machines. MOLINS ORGANISATION Ltd. Oct. 14, 1963 [Oct. 15 1962], No. 38925/62. Heading A2C. Cigarette components are joined by a uniting band by rolling the components between two surfaces which move at different speeds in the same direction. A web W, e.g. of cork, is drawn by rolls 5, 6 over a guide 3 to co-operating knives 8 and 10 where it is cut into uniting lengths L. The knife 10 is fixed and the web is held away from the knife 10, except during cutting, by a pivoted arm 11 operated by a cam 14 on the shaft of knife 8. To space the cut lengths the roller 6 is accelerated during cutting to a speed in excess of its normal speed and equal to that of a suction roller 15, between which and idler rollers 16 and 17, the cut length L is passed to a perforated endless belt 23. The belt 23 passes around suction rollers 24 and 25 and over a suction groove 29. Adhesive is applied to the lengths L by an adhesive roller 35. Alternatively, the web may be supplied with adhesive as by a device 40. An arcuate heating surface 39 is provided adjacent the roller 25 for rendering the adhesive in suitable state for adhering the components. Double length stubs S are carried in grooves 46 of a rotary wheel 47 and fed to the centre of alternate flutes 50 of a drum 49 between the stops 51 positioned midway along the length of a flute. The remaining alternate flutes have no stops. Cigarette lengths C are fed from a suction wheel 52 into successive flutes 50, those passing into the flutes not having stops travelling to the end of the flutes and those passing into the flutes with stops travelling only as far as the stubs S. The components from successive pairs of flutes are deposited between bars 56, supported between endless chains 58 travelling over sprocket wheels 59, 60, and on an endless belt 41 travelling over rollers 42 and 43. The belt 43 travels more slowly than, but in the same direction as, the belt 23 and the bars 56 travel at substantially the same speed as the cigarette components when they are being rolled between the two belts 23 and 41. Prior to rolling, however, the bars 56 serve to push the cigarette lengths and stub from successive flutes 50 of the drum 49 into axial alignment. Side guides are provided for bringing the components into axial abutment. After the components have been united by rolling, the bars 56 push the assemblies over a bridge 64 on to the arms of rotary wheels 67 for delivering them, after cutting into individual cigarettes by a knife 68, to a catcher band 71.
