Filed: 1973-03-26
Abstract: 1382404 Respiratory appliances ROBERTSHAW CONTROLS CO 26 March 1973 [27 March 1972] 14368/73 Heading A5T [Also in Division G3]  A demand valve for use with breathing or resuscitation equipment comprises a valve 104 to control a gas flow to an outlet passage 114, a valve 124 to vent an exhaust flow from the user to atmosphere, a pilot valve 30 controlling pressure on one side of the valve 104, a diaphragm 42 sensing pressure in the outlet passage 114 for moving the pilot valve between open and closed positions, and a manually actuated button 54 for moving the pilot valve to its open position. The diaphragm 42 'forms one side of a chamber 12 connected by a passage 18 to the outlet 114 which also communicates through arcuate apertures (not shown) with an annular space 88 inside a casing 84 for the valve 104. When the pilot valve is closed, pressure from an oxygen or air mixture supply connected to a radial inlet (not shown) acts through passages 74, 76 on the left hand side of the valve 104 and also through passages 78, 86 and 94 on the right hand side of the valve. When the pilot valve is opened either by the button 54 or by the diaphragm 42, the right hand side of the valve 104 is connected through the passages 94, 16, the space 12 and the passage 18 with the outlet 114 so that the valve 104 is lifted by supply pressure to allow oxygen or air mixture to flow into the outlet through a pair of flap valves (not shown). The outlet 114 may be connected to a face mask and the diaphragm may be displaced to open the pilot valve each time the user inhales. Exhalation raises the pressure in the outlet to close the flap valves and lift the valve 124 from its seat 116 so that the outlet is connected to a vent 118. To prevent the pilot valve being held open by the button 54 during exhalation, the diaphragm 42 is displaced by exhalation pressure against a second spring-loaded button 56.

Title: Means for overcoming the effects of earth reflections in directional antenna systems
IPC: H01Q25/00
Filed: 1940-09-25
Abstract: 577,853. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., and ULLRICH, E. H. Sept. 25, 1940, No. 14557. [Class 40 (v)] A directional radio aerial system for defining a course in a vertical plane by the overlapping of two directivity diagrams is provided with means for eliminating deviations of the defined course due to reflections from the earth. This may be effected by employing an aerial system having a radiation diagram with small secondary lobes and making the centre of the height d of the system such that 2d cos #=2n+1)#/4, where # is the angle which the course makes with the vertical and n is any integer. In order to fix the position of earth, a conducting mat may be put under the mechanical structure. Two antenna arrays of the Yagi type may be used, each consisting of a row of eleven dipoles spaced #/4 apart and excited by a straight transmission line. The two arrays are set at 60 degrees to one another in the same plane-and their height is determined in accordance with the equation given above. They are excited alternately and must not have appreciable coupling. In a modification, Fig. 4, the system consists of four rows of dipoles A1 ... A11, B1 ... B11, C1 ... C11 and D1 ... D11, the second and fourth rows being reflectors spaced a quarter of a wavelength from the corresponding dipoles in the first and third rows and so oriented that the vertical bisects the angle between the radio course and the directions BA and DC. The reflectors may be excited by radiation only. The A and C series are each excited as in the previous arrangement but the C series is excited one fifth of a cycle out of phase with series A, the phase alternating between lagging and leading so as to obtain overlapping directivity curves. The spacing between rows A, C and B, D is four-fifths of a wavelength. The orientation of the elements AnBn and CnDn is effected by pivoting them about the centre points Pn, Qn.

Title: Improvements in or relating to arrangements for locating obstacles by electromagnetic waves
IPC: G01S13/24
Filed: 1945-06-08
Abstract: 606,118. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and HOUGHTON, L. W. June 8, 1945, No. 14633. Addition to 586,833. [Class 40 (vii)] In a pulse radar system as described in the parent Specification, wherein the exploring pulses are derived from a saw-tooth relaxation oscillator and the reflected pulses synchronize a further saw-tooth oscillator, the outputs from the oscillators being combined to provide a train of rectangular waves of length proportional to the range of the reflecting object, means are provided for synchronizing the second saw-tooth oscillator with the exploring pulses when no echo signals are being received. The saw-tooth oscillations generated by gasfilled triode 17 synchronize the pulse generator 2 which delivers exploring pulses to the transmitter 3. Echo signals received at 6 are demodulated and applied to triode 18 to synchronize the saw-tooth oscillations generated thereby. The output from oscillator 17 is inverted by the valve 8 and combined with the output of the oscillator 18, thereby producing rectangular waves which are applied to a suitable limiting device 10 and thence to a direct current meter 11 to measure range. A relay 14 for operating an alarm may be provided in the output of the device 10. Should no echo signal be received, an output from the pulse generator 2 is applied in negative polarity to the amplifier 12 to synchronize the oscillator triode 18, and the meter 11 consequently gives a zero range reading. On the reception of an echo signal, however, a bias voltage is developed by the receiver 6 which cuts off the valve 12 so that the received pulses alone synchronize the oscillator 18.

Title: Improvements relating to furnaces comprising apparatus for feeding a sequence of workpieces therethrough
Inventor: MYNARD LEONARD MAURICE
IPC: F27D3/04
Filed: 1961-04-22
Abstract: 930,162. Controlling furnace heating. MANSILL, BOOTH & CO. Ltd. April 24, 1962 [April 22, 1961], No. 14657/61. Class 51 (1). In a heat treatment furnace of the kind in which a line of workpieces are fed through the furnace in stepwise manner by a reciprocating pusher which acts upon the last workpiece in the line, a fresh workpiece being added to the line after each complete reciprocation, the furnace is provided with a mechanism adapted to reduce the temperature of the furnace after a predetermined interval has elapsed in which no fresh workpiece has been added to said line, thus protecting those in the furnace from overheating, the mechanism being arranged to re-set automatically each time a new workpiece is added to said line. In the form shown the lowering of the furnace temperature is effected through a cut-off valve 15 actuated by the displacement of an operating member 16. A ram 18 is caused to move slowly towards the member 16 by the admission of fluid under control of a throttle 22 to a fluid pressure cylinder 19 in which the ram runs. Passage of the workpiece 11a into the furnace causes a spring loaded plunger 26 to be depressed to actuate a switch 25 to complete an electric circuit to energize a solenoid 23. The solenoid actuates a two-way valve 21 to admit fluid to the pressure cylinder 19 on one side of the ram 18 to cause it to move rapidly away from the member 16 and return to its initial position. Once the workpiece has passed the plunger 26 the circuit is broken and the ram again commences to move slowly towards the member 16. Thus if a failure in the supply of workpieces occurs the plunger 26 will not be depressed and the ram 18 will complete its travel and contact the member 16 actuating the furnace cut-off valve 15.

Abstract: 383,208. Electric discharge tube signs. GOLDBERG, M., 8, Leweston Place, Stamford Hill, London. May 26, 1932, No. 14986. [Class 3 (ii).] Electric discharge tube signs are constructed so as to be legible from both sides without duplication of the characters. In the case of symmetrical letters such as T and A, the tubes 1 are mounted in slots in the plate 2 held in the frame 3, the tube being arranged on each side of the plate in places where it has to be doubled back, as in the horizontal bar of the letter A, and the ends of the tubes leading to the electrodes being hidden by screens 10, 11. In the case of asymmetrical letters such as Sand N, the symmetrical parts 1<1> are arranged in slots and are visible from both sides, while the non-symmetrical parts are arranged in pairs 12, 12<1>, one member only of each pair being visible from a given side. Screening may be effected by arranging these parts on each side of the plate 2 as in the case of the letter N, by providing separate screens 6, 7 as in the case of the letter S, or by coating half of the tube with an opaque covering. The letter presented on one side need not be the same as that on the other ; thus by screening only the top and bottom horizontal members of the letter S on the reverse side, the letter H could be simulated. The invention may thus be applied to horizontally-as well as verticallyreading signs.
