Abstract: 1,257,208. Prospecting. PERKIN-ELMER CORP. 28 July, 1969 [19 Sept., 1968], No. 37737/69. Heading E1F. [Also in Divisions G1, G2 and G3] In an apparatus for measuring fluorescent radiation emitted by a material, which may be used in prospecting for fluorescent minerals, a beam of direct sunlight and a beam containing reflected sunlight and fluoresence radiation from a sample material are modulated at different frequencies by choppers 18, 23, the beams being first combined, then divided by assemblies 25, 29 so that one resulting beam passes through a filter 34 whose pass, band is located within a Frounhofer adsorption line while the other beam passes through a filter. 35 whose pass band is located in the solar continuum close to the said Frounhofer line, the intensity of light passed by each filter being measured to derive the amount of fluorescent radiation emitted by the sample. Surface 31 of the beam splitter 29 has a polarisation coating which rejects one plane of polarisation, and the two filters are of the Fabry-Perot type. Each photomultiplier output 37, 39 is filtered to separate out the components corresponding to the different chopping frequencies, and the four resulting signals from the two photomultipliers are combined using various operational amplifiers (Fig. 2, not shown) to derive a final output corresponding to the fluorescivity of the sample. This output may be displayed on a meter or recorded. By encoding the two beams issuing from the filters at different frequencies, a single photomultiplier may be used. In this way, variations in detector sensitivity are compensated for.  The apparatus may be mounted in an aircraft or other vehicle.

A toy vehicle or boat driven by a D.C. motor has a lever-operated switch to reverse the polarity of the current fed to the motor and a direction indicator comprising a light bulb 19 in circuit with the motor mounted in the body of the toy and moved by the lever so as to emit light through one or other of two apertures 26, 27 in the body according to the position of the lever. Figure 2 illustrates the switch mechanism in a central position in which no current is supplied to the motor. The switch lever_28, which is pivoted at pin 5, carries the light bulb and also a switch plate 4 to which are attached metal strips 15, 16 which pass through slots in the switch plate so that only a small central portion of each lies on the side of the switch plate facing an adjacent fixed plate 1. Metal strips 12, 13 are similarly fixed to plate 1 so that a relatively long central portion of each faces plate 4. Strips 12 and 13 connect to the battery and strips 15 and 16 to the motor and by wires 20 to the bulb. Thus when the switch 28 is moved to the right strips 12 and 16 and strips 13 and 15 are brought into contact so that current is supplied to the motor in one sense while the bulb shows through hole 26 and when the switch is moved to the left strips 12 and 15 and strips 13 and 16 are brought into contact, the motor is driven in the opposite sense and the light shows through hole 27.

Abstract: 1290217 Friction clutches TWIN DISC Inc 23 July 1970 [11 Aug 1969] 35840/70 Heading F2C In an hydraulically operated continuously slipping friction clutch wherein clutch plates 2, 4 splined to a driving hub 1 and a driven drum 5 are clamped together by pressure liquid in a servo chamber 12, the pressure in the chamber 12 is controlled by an acceleration responsive valve D to vary the slip. As shown, in Figs. 1 and 3, pressure liquid is supplied through a duct 16 to an annular channel 15 of the valve D which is controlled by a ball 25 engaging an inclined surface R of a cavity 22. Centrifugal force normally urges the ball 25 to the radially outermost part of the cavity 22 thereby permitting a ball valve 26 to open and supply pressure liquid from the channel 15 through a duct 30 to the clutch engaging servo chamber 12. On deceleration of the driving hub 1 the ball 25 rides up the surface R to close the valve 26 and cut the supply of pressure liquid to the servo chamber 12. A continuous bleed 38 permitting disengagement of the clutch. The supply pressure additionally acts on a ball 36 to make the operation of the valve D independent of the supply pressure. A similar valve D1 may be provided to exhaust the servo chamber 12 during deceleration. The valves D, D1 may act together or they may be responsive to deceleration in opposite directions. The valves D, D1 may be rotated to adjust the sensitivity of the valves. The hub 1 is driven by a turbine T of a torque converter TC. In Figs. 6 (not shown) and 7 a deceleration responsive disc 80 on an inclined surface 89 controls a ball valve 81 in the supply line 83 to the clutch servo chamber (86). In Fig. 8 (not shown) an exhaust valve (91) of the type described in Specification 1,243,720 is provided in the supply line to the deceleration responsive valve. In Figs. 9 and 10 (not shown) a single valve is controlled by two discs respectively responsive to acceleration and deceleration.

The substantially V-shaped forward edge of the guard-plate 26 defines an angle of about 160‹ and the opposite ends of this V-shaped edge terminate at points about 160‹ apart circumferentially on the skirt 20. Directly above the crescent-shaped opening is an upwardly spiralling channel portion 36 supporting a frame 44 acting as an outlet, for attachment to a catcher, at its larger, open end. A blade device 46 rotates in the compartment 34 bounded by the platform 16, skirt 20 and guard-plate 26, and is made up of a metal bar 50 having twisted ends, constituting blades 52.

Abstract: 1310107 Welding by fusion FOSTER WHEELER JOHN BROWN BOILERS Ltd 14 April 1970 [22 April 1969] 20576/69 Heading B3R A method of welding a tube to a tube plate or header comprises locating a spindle 30 in the tube 14 by expanding a lower part 42 of the spindle to grip the tube, and supporting a welding head 90 on a projecting upper part 32 of the spindle so that the head can be rotated relative to the spindle to perform the weld, the depth of insertion of the spindle in the tube being such that, when the welding head is mounted thereon, electrode 100 will be appropriately positioned relative to the area of the weld. As shown at the right-hand side of the Figure, a jig 60 is used to insert the spindle 30 in the tube. The jig makes a snap-fit engagement with the spindle through the agency of balls 70 and a groove 72 in the spindle. A nut 48 on the spindle core is engaged by a hand wheel 64 of the jig while a skirt 74 of the latter abuts the surface of the tube plate when the depth of insertion of the spindle is as desired. Hand wheel 64 is then rotated to draw the spindle core upwards, so expanding its lower portion 42. The jig 60 is then removed from the spindle 30 and welding head 90 inserted in its place (see left-hand side of Figure). The head has a body 92 of boron nitride or talc, with balls for interfitting with spindle groove 72. The torch 96 may comprise a tungsten electrode 100, and inert gas can be directed to the arc. A gear 124 on the head can be connected to a chain or belt drive 126 which can also drive two similar heads simultaneously. A filler ring 20 can be positioned in an annular groove 18 in the tube plate, as disclosed in Specification 1,303,041 to which reference is made.

Abstract: 1313018 Welding by pressure; making welding electrodes PLESSEY CO Ltd 19 Nov 1971 [31 Dec 1970] 61978/70 Headings B3A and B3R A welding electrode, e.g. a spot-welding rod or a seam-welding roller, for the electrical resistance welding of zinc and/or tin coated metal includes a body member of copper or a copper-biased alloy and has an electroless nickel/phosphrous alloy coating on its welding- face or faces, preferably in a thickness range of 0À0001 to 0À010 inch. This reduces the high erosion rate of the electrode which is due to the alloying of the copper with the zinc and/or tin coating on the metal. In a preferred electrode coating process, coating is deposited on to the welding faces of a beryllium-copper electrode from a solution of nickel chloride, sodium citrate, sodium hypophosphite and water in the ratios of 3 : 10 : 3 : 100 by weight. The solution is controlled to a temperature of the order of 95 C. and a pH value of between 8 and 9 which is maintained by adding caustic soda to the solution. Sodium hypaphosphite is also added in the range of 4 to 5 grams per hour during deposition in order to obtain the correct solution balance.
