Title: Improvements in or relating to vacuum brake apparatus for railway vehicles
IPC: B60T13/46
Filed: 1923-12-10
Abstract: 222,351. Peters & Co., Ltd., G. D., and Rawlings, V. P. Dec. 10, 1923. Fluid-pressure.-The diaphragm lift valve of a guard's application valve for vacuum brakes is manually operated by means permitting the admission of air at the valve to be regulated as desired and such that, with the parts in the normal position, the lift valve may function as usual as an accelerating valve for emergency applications of the brakes. The valve comprises as usual a lower portion 1, connected to the train pipe at 2, and separated from a vacuum chamber 3 by a diaphragm 4 to which is connected a lift valve 5 normally seating at 6, the space between the members 4, 5 being open to atmosphere through ports 7. An equalizing passage 8 in the valve stem 9, terminating in a cross port 35, connects the chamber 3 to the train pipe. Manual control of the valve is effected by a handle 13 moving between stops and mounted on a shaft 14 which carries cams 25, 26 adapted to engage surfaces 27, 28 formed in a recess or hole 29 in the stem 9. When the handle 13 is rotated from the normal position the cam 25 effects a gradual opening of the valve, whilst the cam 26 engages the surface 28 to prevent movement of the valve by other means, and also serves to close the valve positively when the handle is returned. The admission of air is further graduated by means of a coned plate 10 mounted on the underside of the valve, and adapted, on its initial movement, to afford only a small passage for the air entering the train pipe. As shown in Fig. 3, when the valve is in its closed position, the cam 26 is located over a recess 30, so that the valve is then free to lift to function as an accelerating valve in an emergency application of the brakes. Premature closing of the valve, when it is so actuated, is prevented by a sleeve 31 which is held by a spring 33 normally clear of the ports 35, but which covers these ports as the valve rises, so that equalization between the train pipe and the chamber 3 can be effected only through a leakage groove 36. Alternatively the passage 8 may extend to the end of the spindle and the sleeve be so arranged that it closes the passage when the valve rises, in which case a leakage groove would be provided either in the spindle head or in the sleeve. The usual vacuum gauge 38 is provided and it may be secured in place by a screw plug 43 located inside the casing and engaging the socket 40, so as to minimize the liability of theft. Alternatively, the stem 41 of the gauge may pass through the casing and be secured by a nut screwed from within.

IPC: C08G77/00
Filed: 1950-12-22
Abstract: Thermosetting materials are made by reacting one or more silanes of the general formula RnSiX4-n, in which R is a saturated aliphatic hydrocarbon radical containing less than seven carbon atoms or a monocyclic aryl radical, X is alkoxy, acyloxy or chlorine, and n has an average value from 0.9 to 2.1, with a glycerine ester formed by reacting glycerine with a dicarboxylic acid or anhydride thereof in amount such that the molecular ratio of glycerine to acid or anhydride is from 1.5 to 2, the glycerine ester being employed in amount such that the ratio of silane X radicals to glycerine hydroxyl radicals is from 0.1 to 1, and thereafter reacting the resulting product with dicarboxylic acid or anhydride in amount such that the ratio of the sum of the total carboxyl radicals plus silane X radicals to glycerine hydroxyl radicals is from 0.9 to 1.2.  The silanes RSiX3 and/or R2SiX2, with or without SiX4 and R3SiX, may contain methyl, propyl, butyl, cyclohexyl, cyclopentyl, phenyl, tolyl, chlorophenyl or xylyl as the R substituent, and chlorine, methoxy, ethoxy, butoxy, stearyloxy, 2-ethylhexoyloxy, benzoyloxy, or lineoleyloxy as the X substituent.  Acids specified are phthalic, malonic, maleic and fumaric acids.  The reactions between the silane and glycerine ester and the silane ester and acid or anhydride may be effected at 30 DEG  to 250 DEG  C. and 100 DEG  to 250 DEG  C., respectively.  The process may be carried out in the presence of solvents such as aromatic hydrocarbons, alcohols and ketones.  In examples: (1) glyceryl phthalate is reacted with a phenylmethyldichlorosilane and phenyltrichlorosilane mixture and the resulting product is reacted with phthalic anhydride; (2) a phenylethoxy-2-ethyl-hexoyloxy silane, made by reacting phenyltriethoxy silane with 2-ethylhexoic acid, is reacted with glyceryl-phthalate and then with phthalic anhydride; (3) the product of glyceryl-phthalate and phenylmethyldiethoxysilane is reacted with phthalic anhydride; (4) phenylmethyl-di-(2-ethylhexoyloxy) silane is reacted with glyceryl phthalate as in (1).  The products or solutions thereof in solvents such as xylene or cyclohexanol may be used for coating metal surfaces, followed by baking at 100-250 DEG  C.

Patent GB-392912-A (GB)
Title: Improvements in engine mountings for motor vehicles
IPC: B60K5/12
Filed: 1931-11-16
Abstract: 392,912. Engine mountings ; torquerods. TROTT, R. S., 704, Equitable Building, Denver, Colorado, U.S.A. Nov. 16, 1931, No. 31671. [Classes 79 (iii) and 79 (iv).] The weight of the engine on a motor vehicle is carried by front and rear resilient mountings allowing oscillation of the engine about a longitudinal axis whilst the torque reactions are transmitted to an axle of the vehicle through a torsionally resilient connection. Buffer devices may be provided to prevent excessive oscillation. In Fig. 1, an engine and clutch unit 1 is shown mounted, at the front end, in a rubber ring 4<1> housed in a split bracket 4 on the front cross-frame member 8 and, at the rear end, in a roller bearing 5 seated on a rubber pad 7 on a cross-frame member 6 which may in addition be connected to the longitudinal frame members 2 with interposed rubber mountings 6<1>. A transverse spring 11, the ends of which are attached to the engine unit, carries a bracket 12 to which is pivoted the rear end of a torque reach 9 attached to the front axle 10. The driving reactions are thus taken by the torque reach 9 directly to the axle 10, cushioned by the spring 11, and an orbital or floating cushioning movement of the engine unit will be permitted by the mountings 3, 4, the orbital movement at the front preferably being greater than at the rear end. Rubber &c. cushioning devices 14 carried at the ends of a cross-piece 13 come into action in the event of excessive oscillation. Either of the mountings 3, 4 may be employed at either end of the unit. The form of mounting shown in Fig. 9, with rubber blocks 17, may be employed for cither of the end supports 3, 4 or for the connections 6<1>, 14. In Fig. 3 the rear mounting 6<1> for the unit is of this form, the torque being taken to the rear axle by a torque tube 22 and frame 9<1> connected to a pivoted bracket 20 on the engine through springs 23. In Fig. 7, which shows a front-axle drive, the rear cross-frame member comprises a spring 45, whilst the torque member 49 is connected to the engine unit by a ball- and-socket joint 41 in conjunction with a transverse spring 47. Other forms of ball-andsocket and universal connections between the torque member and engine unit in association with rubber, coil, and laminated springs are described (Figs. 4, 5, 6, and 8, not shown). The buffers 14 may comprise hydraulic, pneumatic, frictional or other forms of shock absorbers. The torque reach 9 may be pivoted to the axle 10 when this is sufficiently constrained otherwise as by longitudinal springs. Reference has been directed by the Comptroller to Specification 26252/02, [Class 79, Locomotives &c.].

Abstract: 944,737. Endless conveyers; rotary conveyers. ANCHOR HOCKING GLASS CORPORATION. Sept. 5, 1961 [Sept. 8, 1960], No. 31889/61. Heading B8A. [Also in Division G1] In a flaw-detecting machine, transparent jars 3 are conveyed by belts 5, 15, 24, 28, 38, 39 to each inspecting station 6, 7, 8, 9, 10, 11 comprising a pair of photo-electric sensing means 76 (see Division G1), adapted to detect a particular fault. At each station the jars are transferred to the pocket wheels 14, 21, 25, 35-37 which position the jars 3 under each of the sensing means 76. The sensing means are then lowered into the jars which are then rapidly rotated in opposite directions. If a fault is detected the jar is rejected by means of a gate 20 and reject belts 17, 18, 19. If no fault is detected the jar is passed to the next station. The sensing means 76, the rejection gates 20 and rotating pocket wheels 14, 21, 25, 35, 36, 37 are synchronized and driven from a common motor 41. The motor 41 drives the shaft 42 through pulley 44 and gears 47. This shaft is coupled to the shaft 48 through an intermittent drive coupling 49. The shaft 48 is coupled to each rotating pocket wheel by bevel gears 51 and 52 set to rotate in successive steps of 60 degrees. The pocket wheels are radially adjustable (Fig. 5, not shown). The sensing means 76 are connected to the shaft 42 through skew gears and cams 59-64, the conveyer belts 5 and 40, and the reject belts 17, 18 and 19 are driven from the end cam-shaft 65. A separate drive motor 81 is provided for rotating the jars in opposite direction whilst under the sensing means. An air operated brake (Figs. 27 and 28, not shown), stops the rotation of the jars and the pocket wheels.
