Abstract: 828,893. Valves. BLACK AUTOMATIC CONTROLS Ltd., and BLACK, A. Dec. 23, 1955 [Dec. 23, 1954], No. 37266/54. Class 135. In a manually or power-operated fluid control valve having a disc-like valve member 8 movable axially into and out of engagement with an annular seating 4, the valve member during the final fraction of its closing travel engages a switch operating member 14 resiliently biased towards the valve member, so as to displace it axially in the direction of travel of the valve member. The member 14 operates a switch 13 controlling an external electric circuit and comprises a plunger anchored to a flexible diaphragm 16 and slidable in a sleeve 15. The switch 13 which may be of the microswitch type may open the ignition circuit of a pilot burner when the valve disc 8, which controls the main gas flow, is unseated, and may simultaneously close an indicator circuit showing the main valve is open. When the valve 8 is closed, a circuit for opening a pilot burner valve is closed. As shown, the valve disc 8 is directly operated against a light spring 12 by a solenoid winding 11 surrounding a non-magnetic tube 10 in which an armature 9 is sealed. In a modification, the diaphragm 16 is exposed to the pressure in the outlet 3 and is held in a normal position by such pressure against a spring. On failure of the gas pressure the plunger 14 rises to operate one set of contacts which operate an alarm circuit indicating a flame failure whilst the valve disc is open. On closure of the valve disc 8, a further set of contacts are operated. The alarm circuit is then broken and a " valve closed indicator is operated. The diaphragm 16 may act against a second spring in the last part of its deflection by the valve disc 8.

Abstract: 307,334. Stievenart, A. March 5, 1928, [Convention date]. Addition to 300,921. Density separators. -In apparatus for the removal of dust from a current of gas discharged from a fan, the spiral channels 4 conveying the dust-laden gas from the fan have an increasing crosssection near their outlet. This increase may be obtained by increasing the dimension in the radial direction shown by the arrow y, or in the axial direction shown by the arrow z. The dust-laden layer of gas in each channel passes into a duct 10 the entrance to which is controlled by a hinged shutter 9<a>. The ducts 10 are deflected gradually from the clear air chimney 8, and they convey the dust laden gas to a separator 11; these ducts are also made with an increasing cross-section. The ducts may lead to different separators, or as shown, two ducts may lead to one separator. The coarse particles pass through the opening 11<b> into the vessel 13 where they settle; the gas is returned from the vessel 13 to the separator beyond the opening 11<b>. Any fine particles left in the gas are removed by making the gas pass between baffles over which water is sprayed; a trough 11h permits water to be discharged outside the apparatus. The gases may also be moistened at the inlet to the separator.

Abstract: 1,158,129. Recording and playback; associated working. EASTMAN KODAK CO. 2 Sept., 1966 [7 Sept., 1965], No. 39275/66. Heading G5R. A synchronizing unit 80 is provided for use in combination with a tape recorder 20 and a slide projector 11 which is electrically operable by remote control 16 for slide changing, the unit 80 being connectable into the circuit of the remote control 16 and having a feed line 39 insertable into an input terminal 26 of tape recorder 20 during recording and into an output terminal 28 during playback and the unit 80 comprises a circuit component across which in use during recording a first voltage is developed each time a slide changing operation is initiated which voltage can be fed by line 39 to input 26 and across which in use during playback, a signal fed by line 39 from output terminal 28 develops a second voltage for initiating a slide changing operation. On closing a switch 36 by hand, a current flows through lines 44, 43 in synchronizing unit 80 and switch contacts 56 to energize a solenoid 50. This trips a single revolution clutch causing a single forward slide change cycle. Tripping of the clutch opens contacts 56 so that solenoid 50 ceases to be energized. If switch 36 remains closed a voltage will appear across the open contacts 56 and across a voltage divider 65 in synchronizing unit 80. Part of this voltage is fed through the feed line 39 and plug 40 to a microphone input terminal 26 to be recorded by a tape recorder 20. When a switch 37, on the control unit 16, is closed current flows through lines 44, 42 to energize the solenoid 50. The solenoid will remain energized as long as switch 37 is held closed to produce the desired one or more slide changes in the reverse sense. Circuitry comprising a silicon controlled rectifier 70 is provided in synchronizing unit 80. When tape recorder 20 is played back by inserting plug 40 in the audio output jack 28 the previously recorded slide-change pulses will trigger S.C.R. 70 so that it passes a half wave-rectified D.C. current to solenoid 50 through lines 44, 69, 43 and contacts 56 to momentarily energize solenoid 50 to change the slides in the forward direction.
