Title: Improvements in and relating to sealing machines for the sealing of glass tubes, ampoules and the like
IPC: B65B7/16
Filed: 1948-03-08
Abstract: 640,416. Rotary conveyers. COZZOLI, F. J. March 8, 1948, No. 7143. [Class 78 (i)] [Also in Group XXIII] A machine for sealing glass ampoules or the like includes a conveyer comprising a rotary carrier 24 the thickened rim 30 of which is slotted to receive radially adjustable V-blocks 32 which are clamped by screws 33. The blocks are adjusted so that the ampoules t extend slightly beyond the rim of the carrier and are thus retained in position by arcuate, stationary, guide sections 36, 36a, 37, 38. The bottoms of the ampoules rest upon a stationary, vertically adjustable circular track 11a. The sections 36, 38 are spaced slightly from the carrier 24 and do not press upon the ampoules, but the section 36a is pivoted at one end 36b to the track 11a, and is pressed inwardly at the other end by a spring, so that the ampoules are held as they pass towards the heating- zone h. At the heating-zone, they are held more firmly by the section 37 which is pivoted at 39 in a radially adjustable block 40, clamped by screws 41, and is forced towards the carrier by a plunger 42 slidable in the block 40 and acted upon by a spring 43. The inward movement of the section 37 is limited by an abutment 44. The ampoules are sealed (see Group XXIII) whilst held by the section 37 from which they are delivered to the section 38 which has a tangential extension parallel to a stationary wallmember 46. A finger 45 at the end of the wall 46 projects into a peripheral groove in the rim 30, the blocks 32 being grooved to preserve the continuity of the peripheral groove. The finger 45 thus removes the ampoules from the V-notches and guides them into the space between the walls 48, 46. The ampoules are prevented from falling over by a sliding block member 106, having ribs 107 of different widths, a rib being selected for insertion between the walls 48, 46 according to the adjustment of the wall 46 by the means 50, 51.

Title: A new or improved safety device for gas burners
IPC: F23N1/00
Filed: 1941-06-07
Abstract: 546,227. Fluid-pressure servomotor control systems. BRITISH BRASS FITTINGS. Ltd., and SALINGER, G. T. June 7, 1941, No. 7235. [Class 135] A safety-device for gas burners of the kind in which the gas supply is controlled by a main valve actuated by gas pressure acting on a diaphragm under the control of a thermally-actuated auxiliary valve subject to the heat of a pilot burner flame has the auxiliary valve so arranged that when its associated thermal element is cold it connects the two chambers on opposite sides of the diaphragm so permitting the main valve to close. As shown in Fig. 1, the main valve 4 is carried by a diaphragm 3 separating a casing into two chambers 1, 2, the chamber 1 being directly connected to the main supply conduit A while the chamber 2 is connected to the supply conduit through an adjustable throttle 6. A narrow bore pipe 8 connects the chamber 2 with a casing housing a spring-loaded valve 12 having an adjustable byepass 14 and actuated by a thermosensitive tube 9 immersed in the water space of a heater F heated by gas passing the valve 4 to a burner E. The safety-device comprises a casing connected by a pipe 16 with the main gas inlet and by a pipe 15 with the casing of the thermostat C if such is used or this is dispensed with the pipes 8 and 15 are connected by a pipe 48. A valve member 21 adapted to cooperate with opposed seatings 19, 20 is actuated by a thermo-sensitive tube 17 acting through a rod 18 and stiff spring 22. To open the main valve a self-closing valve is opened by a push to permit gas to pass from the pipe 16 to a pilot jet 32 in a cap 31 where it is ignited. This flame heats the tube 17 causing the valve 21 to move away from the seat 20 permitting gas to pass to the pilot burner 26 where it is ignited by the flame from the jet 32. Further heating of the tube causes the valves 21 to engage the seat 20 so isolating the chamber 2 from the pipe 16 the pilot flame now being supplied through the pipe 15 from the chamber 2 reduces the pressure in this chamber and permits the main valve to open. Should the pilot flame be extinguished the valve re-establishes communication between the pipes 15 and 16 and allows the main valve to close. In the form shown in Fig. 2 the seat 20 is made adjustable. The tube 17 may be replaced by a bi-metallic strip or disc or by a bellows containing a fluid.

Title: Storage matrix comprising tunnel diodes
IPC: H03K3/315
Filed: 1963-02-22
Abstract: 1,002,727. Tunnel diode matrix stores. STANDARD TELEPHONES & CABLES Ltd. Feb. 22, 1963 [Feb. 24, 1962], No. 7268/63. Heading G4C. [Also in Division H3] In a tunnel diode matrix store in which each diode is connected through resistors to the column and row wires, read-out is effected by applying pulses to the tunnel diodes in a row so as to render individual read-out diodes conductive if the tunnel diodes are in one binary condition, the read-out diodes in each column being connected to a line common to the column. The Figure shows a storage matrix comprising a number of tunnel diodes TD biased by a current Io so as to have two stable operating conditions. The tunnel diodes may be reset to the low voltage condition by momentarily interrupting the supply current and may be set to the high voltage condition by applying a half amplitude pulse simultaneously to a row line y and a column line x. In the high voltage condition the bias on the coupling diodes D is reduced to such a value that the diode is almost conducting, and non-destructive read-out may be effected by momentarily open-circuiting a switch F shunting resistor R1 so as to reduce the diode bias. Current will accordingly flow in those coupling diodes which are connected to tunnel diodes in the high voltage state and produce an output pulse in the column lines A1, A2 &c.

Title: Improvements in mechanism for removing and replacing the doors of horizontal coke ovens
IPC: C10B25/14
Filed: 1920-03-10
Abstract: 152,573. Wilputte, L. March 10, 1920. Coke ovens.-A mechanism for removing and replacing the doors of horizontal coke ovens consists of a lever G adapted to engage the top end of the door and pivoted at about the level of the top of the door, so that the door hangs vertically when suspended from the lever and, on raising the lever, moves first in a vertical direction, but as the upward movement continues moves also horizontally away from the oven. The hook H by which the lever G engages the eye B<3> on the door has an arm H' connected by a link K' to a counterweighted rock-arm pivoted at K near to and at the same level as the axis G' of the lever G, a stop K<4> limiting the movement of the rock-shaft K in one direction. The hook H is thus maintained in a vertical position and also caused to engage the eye B<3> automatically when the lever G descends The lever G is mounted in a carriage running along the coke-oven bench and is operated by a cable and hoist J. The door is locked in closed position by a bar B<7> thereon engaged by inclined guides C<2>, and a guide-rail D<3> on the carriage prevents swaying of the door when lifted clear.

Title: A foldable umbrella, parasol or the like
IPC: A45B19/00
Filed: 1922-03-14
Abstract: 194,935. Faik, G. A. March 14, 1922. Folding umbrellas; ribs; sticks; handles; topnotches.-The staff or stick and the ribs of a folding umbrella, parasol, &c. are each composed of sections hinged together by links and are held rigid or released for folding at will by means operated at the handle end of the staff. Fig. 7 shows a section of the umbrella &c. when folded, Fig. 1 shows it opened, and Fig. 16 shows the operating mechanism in the handle 2, and links 4 joining two of the four tubular handle sections 1. The ribs are formed of tubular sections 7 and each rib is hinged to the head or top-notch 9. To hold the rib and stick sections rigid, each joint has a tube length 26 forming a slide connected by double cables 27 passing over pulleys 16 to the stick section, where thev are united to a cable 36 in the stick passing over a sprocket 38 at the handle section. In operation, to close the umbrella, the knurled member 41 at the handle is turned a little, which by turning the sprocket 38 to move the cable, withdraws the slides 26 from the joints at the top notch only so that the umbrella may be closed as an ordinary umbrella with full-length ribs. Further turning of the knurled member 41 withdraws all the slides 26 from all the joints so that the ribs and stick may be folded up as shown in Fig. 7. The. outermost rib sections have guide-pulleys 23 round which the cables pass, and the caps 24 serve as rib tips for the cover 20. The handle is split in two parts 2, 3 held together by screws 45 or by a threaded cap. The joints may be provided with auxiliary latches 50, Fig. 16, hinged at 51 and having portions 52 to engage with recesses in the opposite member. The guide-pulleys in the top-notch portion may be dispensed with and the bearing plates are then rounded off to reduce friction on the cables.

Title: An improved "one-shot" pneumatic percussive tool
IPC: B25D9/08
Filed: 1937-03-13
Abstract: 491,255. Percussive tools. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., and REAVELY, T. C. March 13, 1937, No. 7462. [Class 124] In a single-blow pneumatic percussion tool of the kind comprising a cylinder 1, a piston 2, and a trigger 7 for moving valve means into either of two positions, the valve means comprise a primary valve 4 and a secondary valve 5, the latter functioning as a pilot inlet valve in one position and as an exhaust valve in the other position. In its normal position the valve 4 functions as an exhaust valve to relieve any pressure air accumulated on the rear side of the piston, whilst in its actuated position it functions as a main pressure air inlet. The trigger 7 engages a bifurcated end of the valve 4, and the valves 4, 5 are held in their forward position by springs 8, 9. When the trigger is in its normal position, pressure air supplied at 10 passes through pilot port 15, groove 5a in valve 5, port 16, and front exhaust port 17 into the cylinder 1 and presses the piston 2 to the rear, any pressure 'air behind the piston being passed through the arm 14a of a bifurcated port 14, port 4b in valve 4, and outlet 21 to atmosphere. When the trigger is depressed, the pilot exhaust 11 is closed and pressure air from inlet port 10 passes through the main port 13 to the cylinder and is available directly the piston 2 has passed the port 13. Further movement of the valve 4 connects the pressure air to both arms 14a, 14b of port 14. Air passing through the arm 14b moves the valve 5 to the rear thereby closing port 16 and opening the front exhaust port 17 to atmosphere by way of port 18, groove 5a, and port 19. Air passing through the arm 14a to the rear end of the cylinder 1 causes initial movement of the piston 2, this movement being continued by the air from the main port 13.
