Title: Spectrometry
IPC: G01N21/33
Filed: 1972-07-03
Abstract: 1402301 Spectrophotometers ENVIRONMENTAL DATA CORP 3 July 1972 [1 July 1971] 31089/72 Heading G1A In a spectro-photometer, e.g. for determining the amount of nitric oxide in a gas mixture, one measurement is taken at an absorption frequency and is compared with the mean of two measurements at non absorption (i.e. continuum) frequencies chosen so that they lie on either side of the absorption frequency. The apparatus has a set of output slits which select these three frequencies; Fig. 5 shows a plate 85 having three apertures 86, 87, 88 which can be selectively exposed by a vibrating mask 89. As seen by comparison with Fig. 6 this mask either exposes the two outer apertures through which the two continuum frequencies pass, or exposes the central aperture through which the absorption frequency passes. The mask vibrates at about 40 Hz and is driven by a pair of coils and a resonant support, Fig. 8 (not shown). A photo-detector receives the frequencies selected by the mask and separates them into two signals, one for absorption and one for continuum. The ratio of the signals forms the output, Fig. 4 (not shown). The apertures are sized such that the sum area of 86, 87 is the same as the area of 88. Nitric oxide measurement: Fig. 1 shows a solid curve for SO 2  and a dotted one for NO. To detect the latter the absorption frequency can be that represented by the vertical line 72 and the two continuum frequencies would then be at lines 73, 74. It is also possible to set the absorption frequency at an absorption peak for SO 2 , e.g. line 78, and remove the effects of SO 2  by setting the continuum frequencies at other SO 2  peaks, e.g. 79 and 80. Because of the wavelengths used the radiation paths in the apparatus may be long and will cross, Fig. 9 (not shown), in which case the mirrors used to determine the path are tilted so that adjacent paths pass under one another to avoid interference. The spectrometer has an input chopper mask operating at a frequency different from that of mask 89, e.g. 800 Hz. The method of measuring is claimed in Specification 1402302.

Title: Improvements in liquid fuel atomisers
Filed: 1920-11-06
Abstract: 174,763. McKean, J. G., and Jomes, R. F. Nov. 6, 1920. Plug cocks.-In a liquid fuel atomizer bracket 1 such as described in Specification 161,840, the liquid fuel shut-off valve is replaced by a shut-off plug cock provided with a handle 23 having one end 24 shaped to shroud wholly or partially the hand-wheel 4 of the pinching screw 3 when in the open position. Release of the atomizer from the bracket is therefore only possible when the fuel cock is closed. The plug cock preferably comprises two parts 9, 10 having an interposed compression spring 11 and held in the bracket 1 by a screwed plug 21 engaging a tapered surface 20 on the part 10. The tapered part 9 is formed with a fuel slot 12 registering with the fuel passages 13, 14 in the bracket 1 and the side walls of the passage are formed with a recess 15. A passage 16 leads from the slot 12 to the space 19 in the bracket beyond the part 9. The space 19 is closed by a plug 22. The part 10 is formed with a rib 17 fitting in the slot 12 and with a recess 18 forming with the recess 15 a cavity for the spring 11. The movement of the plugcock is limited by a stop pin 25 on the bracket engaging a recessed plate 26 on the plug. When the atomizer bracket is fitted to liquid fuel furnaces of the forced draught type, the controlling air valve to the upper part of the furnace may be linked to the cock handle 23 so as to cut off the air and fuel supplies simultaneously.

Title: Improvements in feed mechanism for drilling or similar machines
IPC: B23B47/18
Filed: 1925-12-12
Abstract: 251,557. Herbert, Sir A., Vernon, P. V., and Wilson, C. Dec. 12, 1925. Drilling-machines.-In a feed-mechanism for drilling and similar machines of the kind in which a hand-operated feed-shaft has means combined with it for bringing a power feed into operation, the feed-shaft is rotated by a hand lever which may be oscillated in a plane containing the shaft axis or transversely thereto, either oscillation bringing the power feed into operation. The invention is particularly applicable to the machine described in Specification 3779/14. and as in the earlier Specification the spindle feed-sleeve 4 is fed by a pinion 3 on a shaft 2 which may be rotated by a hand lever 10, the latter having two V-shaped projections 12 engaging similar notches in a sleeve 8 slidably keyed to the shaft 2 by a pin 7. When the tool encounters resistance, the lever is oscillated about the axis of the shaft and the projections ride out of the notches and displace the sleeve axially against a spring 13, thus engaging clutch teeth 6 on a power-driven worm wheel 5. The clutch may also be engaged independently of the resistance to the tool by oscillating the lever in the plane of the shaft, clearance for this motion being provided at 14. Locking of the power feed may be performed by oscillating the lever first axially and then transversely with respect to the shaft, the projections then riding out of the notches and the lever returning to its central position perpendicular to the shaft axis. An automatic stop for the power feed provided by a disc 16. and a clutch 19 for rendering the power feed inoperative, are described in Specification 3779/14. A pin 18 retains the hand lever in position.

[Also in Group XXXIII] A propulsion-jet unit 4 for a helicopter rotor consists of an outer casing formed into a double wall at its forward end to provide an annular duct 12 which communicates through an aperture 20 with a conduit which extends to the tip of the blade on which the unit is mounted from a gas-producing plant (not shown), consisting of a gas-turbine engine or engines or a separate compressor driven by such engine(s). Arms 10 secured radially on the forward end of the fairing support a central faired body 9 which is connected at its rear end to the fairing by stator blades 18 mounted ahead of a bladed rotor 5 secured in body 9 by a bearing 11. Blades. 6 of rotor 5 carry a shroud ring formed on its periphery with turbine blades 8. Further stator blades 14, 15 connect the casing 4 to a tail fairing cone 16 and stator blades 13 bridge the duct 12. In operation, gas flow from the blade conduit passes into duct 12 to be directed over blades 8 to drive rotor 5 which draws air through the unit to mix with the gases from the gasproducing plant with a consequent reduction in jet velocity and noise. Any one of the rows of fan rotor and stator blades may be angularly adjustable to control the rotor speed. Alternatively, the turbine rotor blades 8 may be of the impulse type and a variable area admission nozzle used.

Title: Process and apparatus for the continuous treatment of heavy oils with a view to their conversion into light products
IPC: C10G11/02
Filed: 1931-11-13
Abstract: <PICT:0376613/III/1> In the conversion of heavy into light oils as described in Specifications 319,341 and 320,286 as modified by Specification 320,287, [all in Class 32, Distilling &c.], by vaporizing the oils mixed with steam, cracking the vapours in the presence of catalysts and dephlegmating and purifying the cracked products, the excess water remaining after the cracking stage is removed by condensing the vapours and steam by interchange of heat with the crude oils, and then separating the water, the condensate being revaporized for fractionation with addition of just sufficient steam for the purpose i.e. about 5 per cent of the weight of material treated.  Oil is led to the upper portion B of a combined vaporizing and cracking element B, C as described in Specification 367,679 and is vaporized with steam supplied through a pipe D.  The vapours pass off through a heat exchanger G where they are cooled by preheating the crude oil passing through a pipe A and then enter a condenser F. The condensate and water are separated in a receiver H and the condensate is pumped through a pipe H2 and the tubes of the condenser and is thus again heated being finally vaporized by steam admitted by a pipe E1, heavy residues being removed through a pipe F1, and used to preheat the oil in an exchanger G.  The vapours are fractionated in a dephlegmator E and then pass into a purification and refining apparatus, constructed as described in the Specifications referred to, to which gases from the separator H are also led through a pipe H3.  The vapours may be byepassed round the exchanger G by a line L1.

Title: Improvements in coin freed amusement machines
IPC: G07F17/38
Filed: 1919-12-16
Abstract: 160,264. Wilde, P. C. Dec. 16, 1919. Tivoli billiards and the like.- Consists in a machine with a number of coin-slots 1, Fig. 1, for a number of players; some of the coins are returnable as a pool to the players, the others pass into a till in payment for the use of the machine. In the machine shown, all the coin-slots other than the first are obstructed by pins. After the insertion of a coin in No. 1 slot, a pusher 2 is depressed and actuates mechanism of which the coin forms a link, which lowers the pin from No. 2 slot, and at the same time depresses an indicator 13a which shows by spots (three in the machine shown) the number of attempts that will be available to the player. The coin passes to a pool receptacle 17 seen from the rear in Fig. 2. The operation is repeated with the coins of the second and third players. The fourth coin enables mechanism to be actuated as described above, and in addition causes a stoppin 21 to be withdrawn from a ball 22 in an inclined trough 22<1>. This ball thereupon rolls into a vacant space below the lowest ball in a vertical column 23. The fourth coin passes to the till 31<1>. Similarly, the fifth coin passes to the till, while the sixth and subsequent coins pass to the receptacle 17. After the ball 22 is released by the fourth coin operation, the machine is available for play. Each player then in his turn first sets a lever-arm 32 to his number and thereby moves a ball-return guide trough 33 into register with the appropriate vertical return tube 34 leading in to the trough 22'. He next rotates a knob 24, which, through a linkage 26<1>, centrallypivoted beam 26 and plunger 25 carried by the beam, raises the column of balls and causes the top ball to pass into a shoot 27 and down into play. The player finally rotates a knob 37<2>, which is connected to the ball-catching cup 37 by links 37<3>, and endeavours to catch the ball. If he succeeds, he returns the ball to the trough 22<1> down a by-pass tube 38, and retains his full number of available attempts. If he fails the ball passes out through the hole 27<2> into the guide 33, and, in falling down the tube 34, actuates a ratchet mechanism, which moves the player's indicator 13a and cancels one attempt. The win. ning player is he who remains in play when all the other players have exhausted their three attempts. The winning player operates a handle 39, and, through link mechanism connected thereto, tilts the coin-receptacle 17 so that the pool coins fall into a delivery tray 50. The handle 39 at the same time actuates mechanism which re. sets the machine so that it is again available for play by the insertion of more coins, as above.

Abstract: 1439521 Recording and playback; transporting record tapes STAAR SA 3 July 1973 [17 Nov 1972 15 March 1973 29 May 1973] 31640/73 Heading G5R The single motor 2 of a tape transport is electrically switched 20 from a normal speed mode, in which it drives a capstan 6, to a fast speed mode, in which pinch roller 16 is retracted, the switching of the motor and the retraction of the roller being achieved manually by means so arranged as to permit these operations to be effected simultaneously by one finger or hand. In addition to capstan 6, the motor 2 also drives a take-up reel 14 via a slipping friction drive 9. As shown, a single manual control 22 actuates both switch 20 and a lever 17 carrying both the pinch roller 16 and a head 15. Alternatively, Figs. 3, 4 (not shown), separate controls (22, 22<SP>1</SP>) may be provided, interlinked (27, 28) so that it is only necessary to actuate the slide (22<SP>1</SP>) for the switch. This permits the pinch roller to be retracted without switching the motor, giving a more gentle acceleration of the tape by the reel drive 9. Alternatively, Figs. 5, 6 (not shown), separate, non-linked controls may be provided, merely being juxtaposed for simultaneous actuation.
