Title: Emergency valve mechanism for vehicle tanks
IPC: B60P3/22
Filed: 1922-07-20
Abstract: 201,752. Percival, S., (Davis Welding & Manufacturing Co.). July 20, 1922. Actuating - mechanism; thermally-actuated valves.-Relates to tank vehicles having one or more compartments for oil, gasolene, &c., with bottom outlets 6, Fig. 2, to pipes 7 extending rearwards and provided with drawoff faucets, and emergency valves 9 for closing the outlets. Control mechanism extends from the valves 9 to a box 4 at the rear and is so arranged that the valves 9 must be closed before the door 5 of the box can be closed; a thermal device is also provided in the box to cause' the valves to close in the event of fire; the valves may be closed from the driver's cab independently of the control mechanism, and a dash-pot device is provided to minimize shock on the closing of the valves by spring action. Each valve 9 is normally held closed by a spring 10 and is connected by a rod 11 to a bell-crank lever 13 operatively connected to a rod 12 which extends along the tank to the rear where it is connected to a crank on a shaft 15 extending down into the box 4 and provided at its lower end with a hand lever 16, Fig. 5. The valves 9 are opened by drawing forward the lever 16 which is held in its displaced position by its tail 17 engaging a shoulder 18, Fig. 6, on a bracket 19, and since the lever 16 in this position projects through the door opening of the box, the door cannot be closed until the lever is released from the shoulder. In the event of fire, this release is effected automatically by a spring-pressed plunger 22 which is normally held up by the short end of a lever 25 engaging a notch 24 therein, the long end of the lever being connected by a fusible wire 27 to a part 28 of the bracket 19. A guard fork 29 protects the wire 27 from accidental injury. To enable the valves 9 to be closed from the driver's cab, the rod 12 is telescopic and comprises a casing 12<a>, Fig. 10, forming the front part of the rod connected to the bell-crank levers 13, and a rod 12b connected to the crank on the shaft 15, the two parts being normally locked together by the corner 46 of a reduced part 44 of a rod 41, rotatable in bearings in the casing 12a, engaging a shoulder 43 on the rod 12b. A cranked end of the rod 41 is connected by a flexible cable to a handle in the driver's cab so that the rod can be turned to free the parts 12<a>, 12b from one another and allow the valves 9 to close without freeing the lever 16. A lever 39 on the shaft 15 is connected to the rod 36 of a piston movable in a cylinder 30 pivoted at 33 and provided with a restricted air outlet controlled by a needle valve 32, the gradual release of air from the space in front of the piston preventing excessive shock when the valves 9 are closing under action of their springs 10.

Title: Controlling the flow of uniform objects in a system for treating the objects
IPC: B65G43/08
Filed: 1968-04-26
Abstract: 1,217,751. Counting and controlling articles transferred by conveyers. GEARCO A.S. 26 April, 1968 [26 April, 1967], No. 20025/68. Heading B8A. In a system comprising a plurality of stations 22, 23 for treating uniform objects (not shown), automatic conveying means 24 between the stations 22, 23, and storage means 25, 26; between a station 22 and the succeeding storage means 25, 26, and between the latter and the succeeding station 23 are provided respective counting devices 55, 52, which are coupled to each side of a differential gear 101 provided with a movable member 17 (Fig. 1) for recording the difference between the numbers registered by the two counting devices 55, 52, and controlling the output of either the station 22 or the station 23. The two respective counting inputs to the gear 101 are by means of shafts 4, 6. The shaft 4 is threaded and engages the internal threaded bore of the boss of a gear 7. The latter is in mesh with a gear 9 which is in splined engagement with the shaft 6. The two gears 7, 9, are coupled together by a member 9 which is rigid with a slide 10 mounted on a rod 11 and which carries a cam 12 co-operating with a follower 13 on an arm 14. A disc 17 pivotally mounted on the pivot axis 15 of the arm 14 is urged anticlockwise by a spring 20 so that a stop 18 of the disc 17 abuts a stop 19 of the arm 14. A spring 16 urges the follower 13 into engagement with the cam 12. Thus the disc 17 normally records the difference between the counting input to the shafts 4, 6, but this can be overridden by manual operation of an arm 21 connected to the disc 17. In Fig. 2, there are two sorting stations 25, 26, and counting devices 27, 37, and 28, 38, at their respective inputs and outputs. Differential gears 33, 43, connected to the counting devices of the respective sorting stations 25, 26, are connected to either side of a differential gear 46, the output of which is connected to a similar gear 49, the other input of which is from the counting device 52. The output of the gear 49 and the output of the counting device 55 are connected to the gear 101. This controls a regulating device 113 which controls an adjustment member 115 of the output of the station 22. As shown the stations 22, and 23, are for bottle rinsing and filling respectively.

Patent GB-861802-A (GB)
Title: Fibrous titanium dioxide and its production
Filed: 1959-06-15
Abstract: Fibrous titanium dioxide having a fibre diameter of less than 25 microns and an axial ratio of at least 10 : 1 is prepared by reacting titanium tetrachloride, tetrabromide, or tetralodide with an oxygen containing gas in the presence of a metal chloride melt.  The metal chloride is preferably an alkali or an alkaline earth metal chloride or a mixture thereof and the reaction is normally effected at 600-800 DEG  C.  The reactants may be fed separately to the melt; for example titanium tetrachloride may be passed into the metal halide melt which is then exposed to oxygen whereupon titanium dioxide fibres grow on the surface of the melt. Alternatively, the titanium tetrahalide/oxygen mixture may be passed over or through the melt. The titanium dioxide fibres may be separated from the melt by solution in water or other solvent for the metal halide and the suspension obtained may be filtered to obtain a mat or felt of titanium dioxide fibres.  The aqueous or other suspensions may contain binders such as organic resins, sodium silicate, colloidal alumina or silica and the suspensions may also contain fillers such as silica, carbon, or asbestos. Examples refer to the use of potassium chloride and sodium chloride melts and mixtures thereof with lithium or calcium chlorides.

Title: Improvements relating to electrical timing circuits
IPC: G08C15/06
Filed: 1946-07-09
Abstract: 614,219. Pulse-generating circuits. SCOLES, G. J., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. July 9, 1946, No. 20507. [Class 40 (vi)] In a strobing circuit as used in a telemetry system, the strobing pulse is maintained always in the same relative position along the forward sweep of the associated time-base scanning voltage by adjusting the strobing circuit in accordance with a voltage proportional to the peak charging voltage acquired by the timebase capacitor. In the Figure the time-base capacitor C1 charges via the resistor R1 and discharges through valve V1 when positive synchronizing pulses are applied to its grid circuit at A. Valves V2, V3 constitute the strobing circuit, V3 being normally conducting and V2 biassed to cut-off by the voltage across the common cathode resistor R2. When capacitor C1 is charged to a sufficiently high voltage V2 conducts and V3 is cut-off a positive pulse appears at B and may be used to inititate some further apparatus. To ensure that this pulse is maintained in the same relative position along the saw-tooth wave when capacitor C1 charges to a higher peak voltage due for example to a delay in the arrival of the synchronizing pulses at A, the voltage across the capacitor C1 also charges a capacitor C2 the value of which and of its associated resistor R3 being such that the potential across them remains substantially unaltered during a cycle of the saw-tooth waveform. The voltage across capacitor C2 which is thus a function of the voltage excursion of the time-base is applied to valve V5 via the smoothing circuit R4, C3. The voltage at the tapping point of the potentiometer R5 in the cathode circuit of the valve, follows any variations in the peak charging voltage of capacitor C1 and is applied to the grid of the valve V3 in the strobing circuit to adjust the point at which the strobing pulse appears. Diode V6 prevents capacitor C1 from charging above a certain predetermined voltage by conducting when this point is reached.

Title: Improvements in or relating to projectiles
IPC: F42C15/24
Filed: 1920-07-10
Abstract: 148,838. Sprague, F. D., and Allison, P. W. Oct. 5, 1917, [Convention date]. Projectile fuses.-Relates to delay-action percussion fuses of the kind in which the faring-pin is normally locked against movement towards the primer, but is armed-after the discharge of the projectile and strikes the primer when the deceleration of the projectile on impact is either considerably reduced, as when the projectile emerges through an armour plate, or ceases when the projectile is brought to a stop. According to the invention, the firing-pin 41, Fig. 1, and the primer 35 with its carrier 31 are associated with means such as balls 40 confined by a sleeve 23 adapted to allow the firing-pin to strike back against the primer only after both the primer and the striker have by their momentum on impact moved forward a predetermined.distance, the balls 40 being then opposite a wider. part of the sleeve 23 thereby releasing their. Hold on the firing-pin. The primer carrier 31 is then gripped frictionally by a tapered ring 55 while the firing-pin is thrust back by a coiled spring or air which has been compressed in front of a piston 44 by the forward movement of the firing-pin attached to the piston. The forward movement of the parts is prevented until centrifugal bolts 50 move out of a groove 53 in the firing-pin during flight. The primer 35 contains fulminate of mercury, and is normally situated in a safety chamber 20; in its forward position, however, it lies within a thin part 30 of the sleeve 23 which is surrounded by a re-inforcing charge 28 of compressed crystalline trinitrotoluene filled in through holes subsequently closed with wax plugs 29. The fusebody 15 is weakened by a groove 21 so that any break due to abnormal stress will be localized at this groove and 'will not prevent the operation of the fuse. In a modification,. Fig. 14, the piston 144 is provided with a ring 86 which normally. lies in a shallow groove 87 and is transferred to a less shallow groove 88 when the piston moves forward on impact; this ensures a sudden backward thrust of the piston at the moment the snapping action of the ring is overcome by the air pressure on the piston, even when there is no sudden deceleration.

Title: Improvements in clutches
IPC: F16D13/71
Filed: 1939-07-14
Abstract: 531,214. Friction clutches. VAUXHALL MOTORS, Ltd. (General Motors Corporation). July 14, 1939, No. 20526. [Class 80 (ii)] In a friction clutch, which is closed by the action of a Belleville spring, the closing is opposed by torsionally stressed spring wires, which ensure smoothness in operation and help to position the closing-spring. The Belleville spring 37 forces a pressure-plate 31 to clamp the driven member 27 against a flywheel 17. A cover 21, fixed to the flywheel, has a rib 41, which takes the reaction of the spring when it is acting on the pressure-plate. The clutch can be released by means of a throw-out lever 51 acting on the spring. A shoulder 39 on the pressure-plate serves to centre the spring. Spring wires 53, having bent ends, each have one end 55 inserted in a hole in the pressureplate, and in the other end, after passing through a hole in the shoulder 39, is inserted in a hole in the cover 21. The wires are twisted during insertion, and act to force the pressureplate away from the flywheel, and to keep the Belleville spring supported on the shoulder 39.
