Title: Improvements in operating means for sliding gear transmissions
IPC: F16H59/04
Filed: 1946-07-12
Abstract: 614,367. Controlling change-speed gearing. FORD MOTOR CO., Ltd. July 12, 1946, No. 20869. Convention date, July 26, 1945. [Class 80 (ii)] [Also in Group XXXI] A sliding wheel change-speed gearing is controlled by two longitudinally aligned striking forks 29, 49, Fig. 8, mounted respectively on a shaft 26 and a concentric sleeve 27 which are alternately axially reciprocable from a normal gate-controlled gear lever 15 through an operating fork 18 which engages both selectively with the shaft or sleeve for reciprocation and also with a yoke 23 which simultaneously locks against axial movement the member not engaged by the operating fork. As shown applied to a motor vehicle transmission gearing mounted in the tubular frame of a tractor, the shaft 26 is slidingly mounted in the gear housing and has the sleeve 27 reciprocably mounted thereon with a three-position friction detent connection 47 therebetween. The yoke 23 is transversely pivoted in brackets 22 and comprises a frame enclosing and swinging with the fork 18 and having cut-away ends 24 straddling the shaft and sleeve. Oppositely disposed shaft and sleeve operating slots 38, 35, Fig. 1, the former accessible through a longitudinal opening 39 in the sleeve, are engaged alternatively by pins 19 on the fork 18, similarly oppositely disposed sleeve and shaft locking slots 41, 36, Fig. 3, the latter accessible through longitudinal openings 34 in the sleeve, being correspondingly simultaneously engaged by the edges of the cut-aways 25 in the yoke ends 24. The engine starter switch 46, Fig. 8, can only be operatively depressed in neutral gear, when bores 43, 42, Fig. 7, in the sleeve and shaft respectively are both aligned with a starter switch extension rod 44.

Filed: 1951-09-05
Abstract: 701,827. Television pick-up tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Sept. 5, 1951 [Sept. 5, 1950], No. 20989/51. Class 39(1) Background noise produced by the secondary electrons released at the signal plate of a television camera tube by a high speed scanning beam, is reduced by arranging an annular electrode close to and positive with respect to the target electrode. In Fig. 1 (not shown), annular electrodes are mounted on both sides of a target electrode of the kind described in Specification 688,959. In Fig. 2, the target comprises an insulating layer 1, a mosaic 4 on one side connected by metallic elements to cavities covered by the signal plate 5. The latter is transparent and photo-sensitive and in turn is covered by a layer 13 of powdered glass and fluorescent material and a thin metal layer 14. The metal layers 5 and 14 are connected together and are capacitively connected to the annular collecting electrode 7 which together with the annular electrode 3 on the other side of the target is connected to the positive pole of battery 8. The high velocity scanning beam 6 penetrates layer 14 and excites the fluorescent layer, the light from which liberates slow photo-electrons from layer 5 which discharge the elementary charges of the target produced by the light or electron image 2 yielding a signal across the resistance 11.

Title: Improvements in apparatus for coupling and releasing gas lamps from their supply pipes when in inaccessible positions
IPC: F21V33/00
Filed: 1938-07-20
Abstract: 517,521. Pipe couplings. SLINGSBY & CO., Ltd., W., SLINGSBY, W., SLINGSBY, W. N. and SLINGSBY, T. J. L. July 20, 1938, No. 21488. [Class 99 (i)] [Also in Groups XI and XXIX] In a detachable coupling for mounting a gas lamp fitting 2 on an inaccessible gas supply member 5 the gas pipes 3, 4 on the fitting and member are sealed by a liquid when the lamp is in its operative position and means are provided to prevent the escape of gas when the parts are separated. In the construction shown, on the cord 7, which passes around pulleys 2a, 2b on the lamp fitting, being pulled the lamp fitting is raised to cause mercury contained in a cup 2d on the lamp fitting to surround the lower edge of the pipe 4 and to lift a plug 9 closing the top of the pipe 4 out of a liquid seal cup 5a on the member 5. Gas can then pass to the fitting 2 through apertures 3b in the pipe 3. The fitting is supported in the raised position by projections 10a on a ball 10 carried by the member 5 engaging recesses 11a in a member 11 rotatable on the fitting. As the fitting is raised the projections 10a engage triangular projections 11f on the member 11 and the member 11 turns to allow the projections 10a to enter gap 11e between the projections 11f. The member 11 is further rotated when the projections 10a engage inclined surfaces 11g. When the fitting is lowered the projections 10a engage in the recesses 11a. When the fitting is again raised the member 11 is similarly turned to bring the gaps 11e opposite the projections 10a and the fitting can then be lowered to an accessible position. To ensure all the projections 10a engaging on similarly inclined sides of the projection 11f one of the projections 11f is slightly higher than the others. The member 8 to which one end of the cord 7 is attached and which carries a pulley 8a from which the cord is led to a securing post is adjustable angularly on the member 10. In a modification the plug 9 and sealing cup 5a are replaced by a ball valve which is displaced from its seating in the member 5 by an apertured member at the top of the pipe 3. Ribs are provided inside the member 5 to limit the displacement of the ball valve.

Abstract: 669,284. Vehicle suspensions. KOLBE, J. Aug. 16, 1948 [Aug. 18, 1947], No. 21580/48. Class 108(ii) The suspension arrangements described in Specifications 641,411, 641,416, 641,417 and 641,418 in which inward banking of the vehicle superstructure is obtained on curves by mounting the wheels on " banking arms," each articulated to the vehicle on an axis inclined in a particular way, is modified by applying the arrangement to at least one pair of wheels having swing- ing half axles. Provision is made to enable the inner ends of the half axles to move laterally of the vehicle to accommodate the banking action, and in the case of driven wheels with a differential, this is conveniently done by appropriate mounting the differential casing in the chassis, As shown in Fig. 1. the rear wheels 9 are driven by swinging half axles 8 through universal joints 11 from the differential. Each wheel is carried by an arm 19 mounted for vertical movement about a horizontal axis 24, so that the helical spring 25 absorbs road shocks, and for movement about the inclined axis 21 to permit banking of the superstructure. The differential casing 10 is articulated to the frame on a vertical pivot 14. the universal joint 16 at the rear end of the propeller shaft lying on the axis of pivot 14. In modifications, pivot 14 may be inclined in an upward and rearward direction, or it may be horizontal as indicated in Fig. 6. With the latter arrangement the helical suspension springs may be replaced by a transverse leaf spring anchored at its centre to the differential casing and connected to each wheel carrier by shackles. In a further modification, Fig. 8, the differential casing may be connected to the frame by a pair of links 33, which may be parallel as shown, or may diverge downwardly.

Abstract: 244,182. Paget, S. C. Sept. 13, 1924. Atmospheric gas and vapour burners; vaporizing-apparatus. - A succession of gaseous combustible charges is delivered under pressure by means of a pump to the fire tube or tubes of a boiler and combustion is maintained under pressure in the form of a series of explosions. As shown applied to a flame tube boiler H the flame tube G is connected to a pump A the piston B of which is driven by a connecting-rod B' and a crank B<2> from a pulley rotated by a belt from a power shaft. At the upper end of its stroke the piston B opens a port F<1> communicating with a supply pipe F for the gaseous or vaporized liquid fuel which is thus drawn in by the vacuum formed in the cylinder. The downward stroke of the piston compresses this charge and at the lower end of the stroke a plunger C integral with the piston B and carrying a packing ring C' opens ports which put the compressed charge into communication with a sparking plug C<2> and an outlet pipe E rigidly connected to the flame tube G. The charge is thus ignited and the flame travels along the coiled tube G which is immersed in water in the boiler H, the hot products being exhausted to atmosphere at the further end of the flame tube. The pump A may supply air to a vaporizer or hot bulb while a small fuel pump delivers liquid fuel to the vaporizer &c. which is heated by any suitable means.
