Title: Improvements in and relating to valves for dispensing fluent materials
IPC: B65D83/14
Filed: 1957-08-02
Abstract: 848,110. Stoppers. MICHEL, D. D. Aug. 2, 1957 [Aug. 9, 1956], No. 24511/57. Class 125(3). [Also in Groups XXVIII and XXIX] A valve for dispensing fluent material from a pressurised container 10 comprises a nozzle member 28 closed at one end by a plug 32 integral with the nozzle and provided with transverse openings 34, the plug seating against a resilient seat member 24, which is extended upwardly to form a sleeve embracing the nozzle and urging the latter upwardly, so that the plug is normally in contact with the seat. When the nozzle is tilted sideways the contents of the container can flow past the plug, through the openings 34 and out through the end of the divergent nozzle. An inwardly directed rib 50 on the sleeve like portion of the member 24 presses on the nozzle and prevents leakage of fluid along the latter. The upper end of the sleeve like portion engages an external collar 36 formed integrally with the nozzle and a locking collar 48 is provided for securely locking the upper end of the sleeve portion to the collar 36. The upper portion of the locking collar is split into a number of segments 48a which resiliently engage the nozzle below the collar 46. The nozzle is also formed with a screw thread 44 which can be engaged by a cover 54, the latter preventing the nozzle from being tilted inadvertently. A gasket 58 of cork or other resilient material is inserted in the uppermost portion of the cover 54 to seal the nozzle when the cover is in position. Reference has been directed by the Comptroller to Specification 771,141.

Abstract: 779,624. Automatic circuit - breakers; mechanical switches. WOLFF, H. W. Aug. 23, 1955 [Aug. 24, 1954], No. 24551/54. Class 38(5) In a circuit-breaker, the moving contact C is carried on a spring-urged arm D adapted to move about a number of fulcrum points, the arm being movable about a first point f when the contacts B, C are being closed, about a second point e when tripping ocurrs and about a third point d<SP>2</SP> at the end of the tripping movement. The second point is provided by a cam e on a pivoted lever E movable manually to open and close the contacts, the arm D pivoting about the fulcrum point f. When an overload occurs, a bimetallic strip H or an electromagnet G turns a member F so moving fulcrum f aside. The arm D is released and pivots about the cam e under the bias of a spring d to open the contacts. At the end of this opening movement the arm abuts the third fulcrum d<SP>2</SP> and rotates about it into the normal open position, Fig. 1, so that the fulcrum f resets. At the same time the spring d returns the lever E to the open position, The contacts B, C are provided with arcing tips b<SP>2</SP>, c<SP>2</SP>, the end of the arm D has a pin and slot connection d', a<SP>3</SP> with the casing and the contact C is pivoted on the arm D. Thus when tripping occurs the end of the arm D moves in a fixed path and a vigorous wiping action occurs at the contacts. A stirrup e<SP>3</SP> on the lever E engages the arm D to provide positive opening should the contacts be welded or the spring d be broken. Specifications 779,625 and 779,626 are referred to.

Abstract: 767,620. Digital electric calculating-apparatus. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Aug. 24, 1954 [Sept. 8, 1953], No. 24664/54. Class 106 (1). [Also in Group XL (a)] Binary addition or subtraction is effected by means of two electron beams; each electron beam has four deflector inputs and a divided target. In a single tube (see Group XL (a)) one target is divided centrally, the other asymmetrically. In a binary adder, Fig. 6, unit negative pulses corresponding to X and Y are applied to D1, D3 and D3<SP>1</SP> as shown, and a unit positive pulse corresponding to a " carry-in " digit at CIN. The arrangement is such that a unit positive pulse corresponding to a " carryout " digit is obtained at COUT and a unit negative pulse corresponding to the " sum " digit is obtained at S in accordance with the addition equations shown. Resistance 14 is twice that of resistance 13 so that a voltage pulse corresponding to 2 COUT is applied to D4. In a parallel adder the carry pulses are linked directly between stages. In a serial adder, Fig. 8, the COUT pulses are delayed one digit period. An anode follower and amplifying valve 20 is included in the feedback link from T2 to D4 to reduce transients, and is coupled to D4 by an isolating condenser 21. The " carryout " pulses from T2<SP>1</SP> are amplified in anode follower 24 and delayed 8 Ás. by delay line 25 before being applied as " carry-in " pulses. The circuit is designed for operation at 120 kc/s. with 5 Ás. pulses.

Title: Improvements in and relating to valves
IPC: F16K39/02
Filed: 1939-08-31
Abstract: 533,527. Valves. BRITISH THOMSONHOUSTON CO., Ltd. Aug. 31, 1939, No. 25008. Convention date, Aug. 31, 1938. [Class 135] A lift valve closure in which the throttling orifice between the valve member and seat decreases progressively in diameter as the valve member is moved to its open position and in which means, such as a pilot valve, are provided for causing the unloading of a portion of the upper area of the valve member preparatory to moving it to the open position, is provided with further means either for effecting the loading of a portion of the upper area of the valve member as it is moved to a pre-determined opened position or with means for precluding the closure of the pilot valve by the movement of the main valve when the main valve is fully open. In the form shown in the Figure the valve member 13 has a convexly curved face co-operating with a convexly curved seat 14 and is formed with a cylindrical extension 28 slidable over leaky packing rings 27 carried by depending cylindrical projection 26 on a detachable cover 24. The balancing chamber so formed communicates with the main outlet 12 through an aperture in the main valve under the control of a pilot valve 34 formed on the main actuating spindle 15 which is guided in a partition 32 in the valve member and a socket 33 in the projection 26. The internal diameter of the extension is made slightly less than the diameter of the circle of contact so that when the pilot valve is initially opened there remains a small downward pressure on the main valve. To maintain a downward pressure as the diameter of the throttling orifice increases during the movement of the main valve to its open position pins 41 are fixed to the projection 26 and have tapered and fluted ends engaging holes in the partition 32 so that as the main valve reaches its open position flow from the balancing chamber is first reduced and then stopped. In a modification these pins are fluted throughout their length and in place of stopping the flow from the balancing chamber they serve as stops preventing the reclosure of the pilot valve by movement of the main valve. A cylindrical strainer 22 is fitted on the inlet side of the main valve and the lower part of the casing is fitted with the usual water drain connection 20 and a steam leak-off passage 21.

Title: Improvements in weighing machines
IPC: G01G23/00
Filed: 1928-09-03
Abstract: 296,672. Garaventa, F., and Tripodi, G. Sept. 3, 1927, [Convention date]. Phonographic indicating- apparatus.-In a weighing- apparatus wherein an acoustic indicator announces the weight, the load on the platform is balanced by a counterbalancing weight rigid with a cam surface which controls the positioning of a soundbox over a disc record. In the application of the invention to a coin-freed personal weighing machine, the passage of a coin down a shoot 2, Fig. 1, displaces a lever 3 thereby tripping a catch 7 and allowing a lever 10 to fall under the influence of a counterweight 11. An electrical contact 14 on the lever engages a tongue 13<1> and starts the driving motor 34<x>, a stop lever 15 being at the same time depressed by the weight 11 to release a shaft 16. The motor drives the shaft 16 through a friction clutch 29 and shaft 27. An eccentric 31 on the shaft 27 raises and lowers a rod 33 connected to a bell-crank lever 34, Fig. 3. The bell-crank lever imparts a sliding movement to a rod 36 terminating in a tooth 37 bearing against the end of a tube 38 which carries a horn 40 and a sound box 39 with stylus 41. A weight 80 acting through a wire 81 causes the tube 38 to follow the tooth 37 until arrested by the descent of an adjustable stop 44 on to the periphery of a cam 21 attached to the load-balancing pendulum 20. In this manner the stylus 41 is brought to the correct position over a phonographic disc record 61. A rack 46 on the tube 38 rotates a toothed wheel 47, and after the setting of the tube a detent lever 55 actuated by a face cam 50 on the shaft 16 locks the tube, in its set position. The shaft 16 also rotates the record supporting table 60 and by means of a second face cam 64 lowers the stylus 41 on to the record to announce the weight. A further face cam on the shaft 16 restores the contact lever 10, Fig. 1, to its upper position and opens the contacts 13<1>, 14. The circuit is however maintained through contacts 13, 14 but is broken, so as to step the driving motor exactly at the end of the cycle, by means of a cam 75 which, operating through a lever 77, displaces the resilient contact 13. The position of the shaft 59, Fig. 3, carrying the record table may be adjusted by screws 63.
