Abstract: 1,245,412. Vehicle fuel tank arrangements. F. GRESTY. 27 May, 1969 [27 Feb., 1968], No. 9431/68. Heading B7H. In a vehicle having pneumatically-operated brakes and selector means for determining which of two fuel tanks containing taxed and untaxed fuel should supply an engine which drives the vehicle and also drives auxiliary apparatus such as a concrete mixer drum, movement of the selector means into a position to supply the engine with untaxed fuel is also effective to apply or maintain application of the brakes to immobilize the vehicle. When the vehicle is travelling and a manually-actuated selector valve 19 occupies the closed position shown, taxed fuel drawn from a main tank 1 through a valve 5 is delivered by a pump 12 to the engine injector 7, excess fuel being returned to the tank 1 through a valve 9. Opening of the selector valve 9 opens a valve 21 which supplies compressed air from a reservoir 15 to brake cylinders 25, 26 and also to the valves 5, 9 which move to positions in which untaxed fuel is drawn from and returned to an auxiliary tank 1. Filters 10, 11 are provided in the supply pipes from the tanks 1, 2, a device 12 visually indicates which fuel is being supplied, and a mechanical metering device 14 registers the amount of fuel supplied to the tank 2. When changing over from untaxed to taxed fuel, a delay device comprising valves 29, 31 and a small air reservoir 30 ensures that all untaxed fuel is cleared from the system before any excess fuel is returned to the tank 1.

Title: Automatic train control system
IPC: B61L3/22
Filed: 1925-04-09
Abstract: 248,945. Howe, W. K., and Bushnell, C. S. April 9, 1925. Centrifugal switches; electromagnetic switches; contacts. - Apparatus for automatic braking of railway trains employs governor - controlled switches adapted to make or break contact at a predetermined speed, and in some cases arrangement is made to delay operation of the contacts until the train has travelled a predetermined distance from the point at which braking action is initiated. A construction of relay is also described. A shaft 54, Fig. 8, carries an arm 136 to the lower end of which is pivoted an arm 138. The upper end of arms 138 has a roller 139 bearing against a cam H on a sleeve 86, and is also connected by a link 143 with a sector 141 carrying an angularly adjustable cam 146 with an incline 146a. Shaft 54 is rotated clockwise, as speed increases, by a centrifugal governor device (not shown), and moves the cam 146 in clockwise direction against the action of a torsion spring (not shown), which also holds the roller 139 against the cam H. Cam H is rotated from the vehicle wheels an amount proportional to distance travelled, the movement being initiated under predetermined conditions by means not shown. When cam H is rotated by sleeve 86, movement is transmitted through roller 139, arm 138 and link 143 to sector 141. The parts are designed so that the combined action of shaft 54 and cam H causes the incline 146a to operate contacts 151, 152 after delay. Cams similar to 141, 146, but operated only by arms on shaft 54, are also described. Fig. 12 shows a construction of relay in which an armature 210 pivoted to a magnetic yoke 205 has an extension 212 pivoted to the free ends of a U-shaped member 215 normally urged, to the right by a spring 217 bearing on the transverse portion of member 215. A transverse insulating roller 220 bears against and serves to operate a contact member 222. All the contacts described are mounted on a shelf 150 in a casing 18 and consist of arms pivoted to standards 153 towards which they are urged by springs 158. One contact arm carries a carbon contact button and the other a silver contact strip.

Title: Hand spray gun
Inventor: BRADLEY RICHARD CHARLES
IPC: B05B9/01
Filed: 1970-02-27
Abstract: 1300961 Airless spraying RANSBURG CORP 27 Feb 1970 [28 Feb 1969] 9628/70 Heading B2F An airless spray gun has the flow of spraying material controlled by a needle valve 58 which is opened and closed by compressed air acting on a piston arrangement 34, effective to move the shaft 38. This compressed air is supplied from passage 17 via a valve consisting of valve stem 21, with grommets 19 and 24 at its ends, slidable in sleeve 22 by means of a trigger 16. Without trigger 16 depressed gasket 24 abuts part 25 of the valve sleeve 20 and prevents compressed air from entering chamber 22. Depression of the trigger compresses spring 27, disengages gasket 24 and simultaneously seals the opposite end of chamber 22 with gasket 29, this allowing the compressed air into the chamber from where it passes through ports 44 to chamber 43 which communicates with a cup shaped member 35 forming part of the piston arrngement. This compressed air pushes shaft 38 against the action of spring 37, and opens the needle valve formed by the tapered end 59 of the shaft and bore 57 which leads to the nozzle tip 54, the coating material being supplied under pressure to the port 71. The piston 34 is sealed by a seal 36 held by a nut and washer, 40 and 39. On release of the trigger the gasket 19 nearest it is disengaged, allowing  the release of compressed air, thus being aided by slots 23 in the valve stem 21, and the other gasket 24 seals chamber 22 from the air supply, thus allowing the spring 37 to close the needle valve and cut off the spray. Three guns may be mounted side by side, the centre one being as above described and the outer ones having their triggers connected to the shaft 38 at extension 65 and operated thereby (Fig. 3, not shown).

Abstract: 801,183. Pipe-joints. ROLLS-ROYCE, Ltd. March 29, 1956 [April 1, 1955], No. 9648/55. Class 99(1). [Also in Group XXV]. Means for securing together end to end two segment shaped pipes comprise radially outwardly-directed circumferentially-extending flanges at the ends of the pipes, the flanges abutting against each other on the one side and on the other tapering outwardly, at least one pair of clamping members shaped to fit over the abutting flanges, the clamping members each carrying at one end, means by which the ends of the two members may be secured together and placed in tension and each carrying at their other ends a part adapted to abut against a surface formed on the flanges and inclined with respect to the radius of curvature of the pipe at that location, the inclination of the surface being such that on tensioning the clamping, members, they are urged radially inwardly on to the flanges and apply to the flanges forces directed axially of the pipe thereby clamping the pipe-ends together, with means for locating the parts carried by the clamping members with reference to the inclined surfaces formed on the flanges prior to the tensioning movement. As shown, each pipe section comprises a flange 12 abutting a similar flange on the adjacent section. Four bands 13 shaped to fit over the pipe flanges 12 are provided with axially directed flanges 13b and adjacent ends of each pair of bands are secured together by tension bolts 14. The opposite ends of the bands are each locked to the pipe sections by means of an end piece 19 secured to the band and having a face which abuts a face 18 formed by portions cut away to present two parallel sided members 12c on the flange. The two faces 18 and 19 are located radially by means of extensions 21 welded to the end pieces 19 and fitting under pairs of lugs 22 secured to the pipe sections. The faces 18 and 19 are so inclined that on tightening the bolts 14 after applying the bands to the flanges, the free ends of the bands are urged inwards towards the wall of the pipe.

Title: Improvements in or relating to circuit-controlling devices for tabulating machines
Filed: 1923-04-09
Abstract: 199,356. British Tabulating Machine Co., Ltd., (Assignees of Lake, C. D.). June 17, 1922, [Convention date]. Statistical machines.-Relates to counter mechanism of machines, such as those described in Specifications 27067/07 a n d 131,277, in which perforated cards pass between electric contacts controlling means for clutching the counter wheels to a driven shaft, and in which means are provided for positively restoring to initial position the clutches and their operating levers and for relatching them. In such a machine, a brush-circuit containing a counter-magnet, is controlled by a mechanically-operated member released on energization of the counter-magnet, and operating to effect the closure of a shunt to the brush-circuit through the counter-magnet, so that the magnet is maintained energized during the card cycle. The counter shown on the left of the Figure is of the kind used in a Hollerith machine with printing-attachments. The machine is started by the closing switch 26 and depressing the key 27, this establishing two holding circuits for the motor 21; during energization of magnet 36 its armature closes a circuit through the brush-bar 17, lines 41, 40, and contacts 33, 34. When a perforation in a card comes under a brush a circuit is completed including line 43 and a corresponding counter-magnet 44, energization of the latter attracting the armature 45 and thus unlatching a lever 46, a blade spring 47 rotating this lever anti-clockwise so as to throw in the clutch 48 and operate the counter wheel 49. At the same time the movement of the spring 47 allows contacts 50 to close and establish a direct shunt circuit from lead 42 through the counter magnets 44. This circuit shunts the card circuit and prevents arcing at the brushes when they leave the perforations in the cards, and also maintains the counter magnets energized during the remainder of the adding cycle, after which the cam 34 opens the circuits. At the end of the adding cycle the counter wheels are disengaged from the shaft 54, and the levers 46 are restored and re-latched by means of a cam 51 and a knockoff bar 52. This also opens the contacts 50. The counter shown on the right of the Figure is used with automatically-controlled machines, where it is desired to break the circuit to the brushes as well as to establish and maintain a magnet circuit. In this modification the card circuit 43<a> extends from the contact-block 14<a> to leads 55,. blade springs 47<a>, initially closed contact 47<b> and the counter magnets 44, upon energization of which these contacts 47b are interrupted coincidentally with the making of contact 50. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of spring- pressed opposed metal balls, or metal balls opposed against corresponding contact blocks, in place of the customary card brushes and contact blocks. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,006,704. Measuring length photo-electrically. ENGLISH ELECTRICAL CO. Ltd. March 19, 1962 [March 17, 1961], No. 9805/61. Heading G4H. [Also in Division G1] Apparatus for measuring a linear dimension of a moving body such as a red-hot steel plate 10 moving on a roller table 12 includes two pivotally mounted photo-electric scanners 24, 25 caused to scan the roller table in opposite directions by a reversible motor 14 driving right- and left-handed screws 18 and 19. The motor also drives a pulsing disc 29 having tracks 30 and 31 of equally spaced holes staggered circumferentially. Fixed photo-electric cells 32, 33 co-operate with the tracks and with a light source 34 to produce output pulses which are fed through switching units 35 and 36 to a counter 37 controlling a visual length indicator 38. The signals from the scanners 24, 25 are fed to the units 35, 36 which transmit the pulses from the cells 32, 33 to the counter 37 only when signals are received from the scanners. When a plate 10 passes across the table 12, the light from it is detected by the scanners 24, 25 for different lengths of time according to the direction of rotation of the scanners and the direction of motion of the plate. The algebraic sum of the resulting pulses at the outputs of the units 35, 36 will give an indication of the length of the plate. If a cold body is to be measured, a fixed light source is placed under the table 12 and the units pass pulses to the counter only in the absence of signals from the scanners. The apparatus may also be used to measure the linear dimension of a stationary body.

Abstract: 804,103. Automatic tuning and impedance matching control systems. STANDARD TELEPHONES & CABLES, Ltd. March 29, 1956 [April 4, 1955], No. 9939/56. Class 38 (4). [Also in Groups XXXVIII and XL (c)] A transmitting antenna is automatically tuned and impedance matched with a transmission line by two servo systems having motors controlled by amplified control signals whose magnitude and polarity are dependent on the error and its sense, and successive reversals of sign of the error signal due to overshoot are used to successively attenuate the control signals. As shown, the antenna tuning is controlled by a shorting bar 7 variably connected between a loading inductance 6 and an earthed container 4 and the impedance of the antenna adjusted by a variable tan 5 on the inductance. Mistuning of the antenna is detected by a reactance circuit X which detects the relative phase between the line voltage derived across shunt circuit 30, 24, 25, 37 and the line current derived from current transformer 22, the two being in phase quadrature, for antenna resonance, at opposite sides of opposed rectifiers 17, 18 due to phase shift networks 28, 29, 35, 31 and 26, 27, 36, 32, and an output dependent on mistuning being derived from capacitor 37 and applied through D.C. amplifier 10 to a servomotor 11 controlling the position of the tuning short 7. Further, each reversal in sign of the output of D.C. amplifier 10 operates a polarized relay 42, 42a energizing a stepping switch 44 so that a wiper 40 is moved one step in turn along a potentiometer resistance 9 at the input of amplifier 10, to reduce the loop gain and motor speed. Similarly, a resistance circuit R with opposed rectifiers 20, 19 measures inequality between the voltages derived from the line and from a tap on the secondary of the current transformer 22, to derive an output to D.C. amplifier 14 controlling through a motor 15 the adjustment of tap 5. Further, each reversal in sign of the output of D.C. amplifier 14 operates a polarized relay 43 energizing a stepping switch 45 to successively step a wiper 41 on resistance 13 so that the input to amplifier 14 is reduced. Manual switches 48, 49 are used to reset the stepping switches 9, 13.
