Filed: 1941-10-23
Abstract: 547,381. Non-refillable bottles. PISANI, F. S. Oct. 23, 1941, No. 13648. [Class 125 (i)] A stopper 10 which will indicate any attempt at tampering with it, or any attempt to refill the (container, has a closed float body 16 which can move in a perforated guide cap 14; the float is held normally by a heavy spherical body 62 in the position shown in Fig. 1, in which the closed base 60 of the float rests upon the inner part of a resilient annular member 32 the outer part of which is gripped between the flange 46 of the guide cap and the shoulder 18 of the casing. The top of the casing is out-turned to form a top 28 and a skirt 30 which can be rolled against the container neck to hold the stopper securely in position. The guide cap 14 is held by a top plate 50 with a raised central portion 52, the plate being secured by the bulged rim 76. Perforations 56 are made in this plate and baffles 58 are provided to prevent the insertion of an instrument for interference. When the bottle is tilted to discharge its contents the float is raised against the weight of the sphere-62 and the liquid is discharged through the openings 36, 44, 56. If any adulterant is passed through the openings 56, the openings 36, 44 are closed by the float, which may then be depressed by the added fluid until the recess 66 is engaged by the resilient member 32 to lock the float in position. When the bottle is tilted, the adulterant will flow out through the openings 42, 56. In a modified form, the valve device is situated same distance below the top flange 28 so that a cork or similar plug can be fitted in the opening of the neck above the one-way device.

Title: Improvements in electric circuit breakers of the gas blast type
IPC: H01H33/76
Filed: 1940-09-02
Abstract: 540,349. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 2, 1940, No. 13749. Convention date, Sept. 1, 1939. [Class 38 (v)] A gas-blast circuit-breaker, comprising a tubular contact 17 movable with a close fit within an insulating, gas - evolving liner 13 to engage a fixed contact 14, is adapted to interrupt a wide range of currents by providing an insulating extension 18 which is threaded into the end of contact 17 and has on its surface a number of longitudinal grooves 19 as shown or (Fig. 3, not shown) helical grooves, all communicating with a header or passage 20 in the region of contact-separation. When breaking large currents, the grooves cause the formation of a number of parallel-connected arcs, and the arc-gases evolved are transferred by way of passage 20 to other grooves. The cross-section of the latter may increase upwards or downwards according as to whether relatively small or large currents are to be dealt with. The liner 13 is held within an insulating cylinder 10 by a threaded member 14a and annular insulating washer 15 which is gripped between the two parts of a conducting housing 12 serving with strips 15 to lead current to contact 14.

Patent GB-1305430-A (GB)
IPC: B60T8/1761
Filed: 1970-03-23
Abstract: 1305430 Antiskid braking systems TELDIX GmbH 23 March 1970 [22 March 1969] 13825/70 Heading F2F An antiskid control system for fluid pressure operated brakes comprises two signal generator arrangements, one 14 of which supplies a continuous, and the other 23, 24 supplies a pulsed signal, the continuous and/or pulsed signal being applied to valves 1, 2 such that the rate of change of fluid pressure as controlled by the valves is less when the pulsed signal is applied than when it is not applied. The signal from generator 14 is derived from a wheel generator and has three threshold values +b, -b 1 , -b 2 . When the deceleration of the wheel reaches the first threshold signal -b 1  appears which causes inlet valve 1 to close through two OR gates 20, 21 and causes generator 23 to pulsate the output signal through OR element 21 thereby pulsatingly controlling output valve 2. The pressure therefore drops with a gentle gradient. Signal -b 1  changes over a flip-flop 16 and triggers a monostable flip-flop 19 through an AND gate 17. Hence on disappearance of the signal -b 1  the input valve remains closed for a time T as a result of the output from flip-flop 19 and the pressure remains constant during this time. The wheel starts to decelerate and the braking pressure is reapplied so that signal -b 1  reappears and the above sequence restarts. When the deceleration exceeds a second threshold a signal -b 2  appears which changes a flip-flop 15 into its operative state and permanantly opens outlet valve 2 through the lower input of AND gate 21. The pressure drops rapidly until the rotary acceleration exceeds a threshold at which point a signal +b appears. If an upper threshold acceleration is exceeded the +b signals ceases and generator 24 effects pulsating of inlet valve 1 until the wheel speed reaches that of the vehicle. At termination of braking a stop-tight switch 25 opens so that the positive potential at the upper input of flip-flop 16 restores the whole arrangement to its original state.

Abstract: 773,387. Percussive earth-boring apparatus. PILLAI, A. Jan. 13, 1956 [May 16, 1955), No. 14023/55. Class 85. In an earth-boring apparatus in which a weighted hollow cylinder 1 is allowed to drop under gravity so that the cutting edge 2 thereof may cut into the ground and is raised together with the soil detached from the bottom of the bore by a winch-operated cable 10 passing over a pulley 22 carried by shear legs 17, the soil within the cylinder is, when the cylinder is out of the bore, ejected by a plate structure 3, 4, 5, 7, 8, slidably mounted in and extending through the end structure of the cylinder, engaging an abutment surface at the head of the shear legs 17 whilst the cable 10 continues to be wound on to the winch so that the cylinder moves upwards relative to the plate structure against springs 13 disposed between the plate structure and the cylinder. In order that the soil shall be discharged clear of the borehole, the pulley 22 is eccentrically mounted on a block 19 pivotally mounted by trunnions 20 engaging in a ring head 18 secured to the legs 17. Stops 25, 26 on a U-shaped bracket 24 secured to the block 19 limit the angular movement of the block. Bearers 27 support the cylinder 1 at an angle to the vertical as the cylinder is drawn by the cable 10 into contact with the bearers and then the lower surface of the block 19. Said surface when the cylinder contacts it is at an angle to the vertical due to the eccentric mounting of the pulley 22.

Abstract: 1,206,411. Spindles. V. H. BALDING. 28 March, 1968 [28 March, 1967], No. 14136/67. Headings B3B and B3C. The vertical spindle of a machine tool comprises a quill 11 into which is drawn a tool-holder 12 by means of an expandable collet 17 engaging in a grooved recess 15 of the tool-holder 12. The expandable collet is moved axially by a sleeve 18 rotatable with the spindle, the sleeve 18 being acted upon by an hydraulic pistoncylinder arrangement 24 via non-rotating plunger 22, sleeve 21 and ring 20. In one embodiment movement of the plunger 22 operates a linkage 25, 26, 27 and 29 to move a second plunger 30 in the opposite direction to plunger 22, a concentric rod 31 attached to the second plunger 30 passes into the expandable collet 17 to engage its jaws in the tool-holder 12. Alternatively the second plunger 30 may be moved hydraulically or in a modification the rod 31 may remain stationary. In this latter case a toolholder 12 is pushed up into the quill to overcome a spring bias and push the expandable collet 17  upwards and over the stationary rod 31 to expand its jaws, the hydraulic piston-cylinder arrangement 24 being then operated to firmly pull the tool-holder into the quill. Driving engagements 14, 14d are provided between tool-holder and quill. When the expandable collet 17 is released on downward movement of the sleeve 18 the tool-holder may be forced out of the quill.

Filed: 1939-05-16
Abstract: 528,896. Gas-blast switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 16, 1939, No. 14651. Convention date, May 25, 1938. [Class 38 (v)] A switch comprises an arc passage of insulating material, relatively-movable contacts for establishing an arc within the passage, a tubular movable contact normally substantially filling the passage, and a plunger formed at least partially of insulating material substantially closing one end of the passage but movable thereinto for restricting the cross-section thereof, whereby the products of decomposition produced by the arc are expelled from the passage through the arc path and tubular contact. In Fig. 1, a pair of similar arc-extinguishing structures are mounted on the insulating plate 10 on a gasreceiving housing 54 having an escape-valve 58, and are connected in series by a bridge-member 30 operated by member 32. Each structure comprises an insulating tube 14 on which is screwed a collar 16 carrying a conducting ring 18 and conducting cap 20, the inside diameter of which equals that of the tube 14. The tubular movable contact 28 substantially fills the tube 14 and co-operates with a sectioned fixed contact 24, between which and an arcing-ring 40 is connected a radial-field producing coil 38 protected by insulation 42 from the arc. Supported on the tube 28 is a plunger 44, the outside diameter of which is such that when moved into tube 14 it forms therewith a narrow arc-passage, for example, 1/32 to 1/8 inches wide, the width being larger when the tube or plunger is of arc-extinguishing gasevolving material. An arc is struck between contacts 24, 28 and subsequently transferred to ring 40, coil 38 is energized, the field of which may be intensified by a magnetic core in the plunger 44. When refractory materials are employed for the tube and plunger, the arc is extinguished at zero of the cycle by deionization in the narrow arcing passage. When gas evolving material is used for those members, the blast escapes through the annular passage 52 and out of the tube 28. The plunger may be provided with circumferentially-arranged channels in which gas emitted at the current-maxima is stored so as to be given up at the current-zero, Fig. 6 (not shown). Grooves or pockets may also be provided along the arc-passage itself by replacing member 14 by a structure of spaced plates 64 clamped between end-plates 68, 70, the latter supporting contact 24 &c. Fig. 4. The spaces 72 between the plates 64 form large storage chambers and provide a larger cooling surface, the cooling being further facilitated by annular metal plates arranged between spacers 74. Alternatively, the plates may be thinner and closer together, Fig. 5 (not shown). Specification as open to inspection under Sect. 91 included also a form using a fixed filling member, Fig. 8 (Cancelled) (not shown). This subject-matter does not appear in the Specification as accepted.
