Abstract: 723,830. Vapour burners. ARMSTRONG SIDDELEY MOTORS, Ltd. Aug. 6, 1953 [Sept. 13, 1952], No. 23056/52. Class 75 (1) [Also in Group XII] In a flame stabilizing device for use in an exhaust reheat system of a gas turbine jet propulsion engine, the supply of fuel for the stabilizing device is introduced into and near one end of a duct 19 disposed in the main gas flow and having adjacent the fuel inlet 22 an opening 24 through which a small amount of the main gas flow can enter, the opposite end 20 of the duct communicating substantially centrally with the upstream end of the stabilizer casing 14. The casing 14 is supported by radial struts 15 which are'secured to the jet pipe 13 by means of bolts 17, and in Fig. 1 the duct 19 extends radially and is in line with one of the struts 15. In a second embodiment, the duct extends co-axially upstream from the stabilizer casing and the fuel supply pipe is led radially across the jet pipe. The fuel passing through the duct 19 is vaporized and enters the casing 14 through swirl vanes 27. Gaseous fluid flowing in the jet pipe enters the casing 14 through swirl vanes 30 which impart swirl in a direction opposed to that of the vanes 27. The means for causing ignition of the fuel within the stabilizer casing so as to form the pilot flame and the means for supplying the main reheat fuel are not shown. In further embodiments, the vaporized fuel and gas issuing from the duct 19 does not pass through swirl vanes 27, but impinges on a flat baffle plate which causes turbulence and directs the mixture radially outwords. In a further embodiment, the vaporized fuel and gas issues through swirl vanes 27 but the gas stream entering the casing 14 impinges on a baffle plate which thereby causes turbulence. Specification 674,641 is referred to, and Specification 705,772 is referred to in the Provisional Specification.

Abstract: 1,128,675. Measuring thermal conductivity electrically. ABCOR, Inc. May 24, 1966 [May 24, 1965], No.23121/66. Heading G1N. [Also in Division H1] Changes in thermal conductivity of a flowing fluid are detected by measuring the changes in temperature of a heated temperature sensitive element, e.g. a thermistor or wire, by detecting changes in its resistance using, e.g. a Wheatstone bridge. In order to eliminate the effects on the measurements of convection currents in the fluid, changes in turbulence or rate of flow of fluid, which would also cause the temperature of the element to change, it is surrounded by beads of low heat capacity and/or density, e.g. of glass, resin, plastics, gas expandable polystyrene, sponge rubber, or hollow metal beads which may be held together by adhesive or by heat sintering their contact areas or surrounding them in a screen of finely divided gas permeable sheet or wire mesh. In the embodiment, a thermistor 18, Fig. 2, or coiled wire (19), e.g. of tungsten, Fig. 3 (not shown)is attached between two supports (14), (16), Fig. 1 (not shown), by platinum wire 20, the supports (14), (16) also acting as electrical connections for the resistor into a Wheatstone bridge circuit. The thermistor or wire is surrounded by tightly packed hollow boro-silicate glass beads 24, held in place by a cylindrical perforated metal screen 22, closed at its top and bottom by electrically insulating epoxy resin material 26. The two supports (14, 16) are mounted on a base (12) in the stream of flowing fluid.

Abstract: 792,321. Machinery safety devices. CROSLAND, Ltd., W. Aug. 13, 1956 [Aug. 12, 1955], No. 23250/55. Class 80 (4) In a cutting, creasing or embossing press of the kind comprising a rise and fall guard to move the operator's hand clear of the platen when feeding takes place, and side guards in front of the platen in such a position that should the operator's hand remain over the guard it will come into contact with a trip rail and move the latter, thereby causing the drive clutch to be disengaged, a brake to be applied and the machine to be stopped, the usual starting pedal is connected to the clutchoperating mechanism through a shaft divided into two parts, one part rotatable by the pedal and normally connected to the other part by a latch carried by a sleeve secured to the first part and engaging a pawl carried by a sleeve secured to the other part, the pawl being lifted by movement of the trip rail to disconnect the two parts and disengage the clutch. The pedal rotates the shaft part A, Figs. 1, 2 and 4, to which a split sleeve a is secured by a bolt a<SP>1</SP>, while the shaft part B controls the clutch and has secured to it a split sleeve b by means of bolts b<SP>1</SP>. The shaft A is urged clockwise in Fig. 2 by a spring c, the movement being limited by an adjustable stud g engaging the machine frame C<SP>1</SP>. Pivoted to a lug d of the sleeve b and urged counter-clockwise thereon in Fig. 2, by a spring d<SP>1</SP> is a pawl D which engages a latch A<SP>1</SP> on the sleeve a, so that counterclockwise rotation of the latch by the pedal rotates the sleeve b and engages the clutch. Operation of the trip rail E<SP>1</SP> by the operator's hand rotates a shaft E and raises a lever F underlying the pawl D to disengage the latter from the latch A<SP>1</SP>, whereupon, whether or not the pedal is still held depressed, the sleeve b is disconnected from the sleeve a, and the clutch operating fork moves by spring action to release the clutch, rotating the shaft B. The clutch is normally held in the engaged position by a plunger acting on the fork and forming the end of a rod to which the rail E<SP>1</SP> is connected. When the rail E<SP>1</SP> is moved to stop the machine, the plunger is withdrawn. The movement of the fork to release the clutch also applies a brake. The trip rail E<SP>1</SP>, Fig. 3, carrying a guard H<SP>1</SP>, can be retained in the safety position against its return spring by a catch lever H abutting a stop h<SP>2</SP>. To release the rail, the latter is moved out of a notch h<SP>1</SP>, and the lever H is pivoted away from the stop h<SP>2</SP> against the action of a spring h<SP>3</SP>.
