Title: Improvements in or relating to machines for closuring bottles or other containers
Inventor: EVANS ARTHUR JAMES PERCIVAL
IPC: B67B3/062
Filed: 1952-04-28
Abstract: 710,387. Closuring containers. METAL BOX CO., Ltd. Feb. 20, 1953 [April 28, 1952], No. 10708/52. Class 125 (2) In apparatus of the kind described in Specification 450,093 wherein screw closures are fed on to supports 6 beneath a plunger 7 which descends and rotates to carry the closure thr;ough the supports and apply it to a container, the closures pass by gravity down a shoot 5 having a resilient gate at its exit end and are pushed one at a time past the gate on to the supports 6 by a reciprocating member. As shown in Figs. 1, 2 and 4, a platform 1 is fitted with spaced brackets 2 the tops of which carry bars 3 the front ends of which are attached to the supports 6 and the rear ends of which carry each am inwardly facing U-shaped channel which co-operate to form the shcot 5. The spacing at the brackets 2 iis adjustable to suit different diameters of closure. The resilient gate is formed by spring plungers 13 carried on the shoot, the tension being adjustable by screws 14. A tongue 39 prevents a closure from rising when ejected 'from the shoot. If the gate jams, the closure forces down :a pivoted plate 15 against a spring 17 to allow ejection of the closure. Platform 1 carries spaced guides 23 for a slider 22 carrying a vertical arm 26 pivoted between two lugs 25. Two bars 21 extend forwardly from the arm 26 and carry at their front end a depending fork 18 entering between the two parts of the shoot. Bars 21 are normally urged to the position shown by a spring 32 acting an ,a projection 29 of the arm 26. A lever 35 engages between two rollers 34 carried on the top of arm 26 .and is reciprocated by a cam 38 through links 40, 41, 42. When the lever 35 moves to the right, Fig. 4, it first tilts the arm 26 clockwise against spring 32 to cause the fork 18 to enter the shoot to feed a closure past the resilient gate during advancement of the slider 22. When the lever moves to the left, spring 32 raises the fork to clear the next closure to be fed and then the slider is restored to its lefthand position. A stop 44 normally engages grooves in the guides 23 and in the slider 22 to prevent advancement of the latter but when a container approaches the capping station it actuates a lever 48 which withdraws the stop 44 against spring action to allow the feed of a closure. Altenatively, an approaching container may actuate directly the lever 35. In a modification, Fig. 5, an approaching container actuates am arm 48a to rock a shaft 59 which results in a plate 54 pivoting downwardly about its pivot 55. This causes descent of a rod 50 having a head 18a formed with an inclined susface 49 which enters between the first and second closure in the shoot 5a to feed the former past the resilient gate 11a. The parts are restored by a spring 63.

Title: Improvements in or relating to the strengthening of thermoplastic sythetic polymeric materials
IPC: B29C48/10
Filed: 1965-03-12
Abstract: Thermoplastic synthetic polymeric material which is essentially crystalline and capable of being strengthened by shearing, is strengthened by subjecting it to a plurality of shearing forces which are parallel to each other at any point in the material, at a temperature below the crystalline melting point of the material, so that in the material perpendicular to the direction of the forces, adjacent macromolecules are displaced relative to each other in paths parallel to the forces, and so that the thickness of the material perpendicular to the forces is not substantially reduced.  Specified polymers are polyethylene, polypropylene, polybutylene, poly - 4 - methylpentene - 1, poly - 3 - methylbutene - 1 and ethylene/propylene copolymers.  Other shearing forces in different directions may be applied simultaneously or subsequently.  Examples describe the application of shearing forces to plates, tubes and moulded articles such as shotgun cartridges.

Title: Method of and apparatus for purifying raw water from humic substances
IPC: C02F1/52
Filed: 1946-04-12
Abstract: 622,282. Purifying water. KARLSTROM. A. M. R. April 12, 1946, No: 11302. [Class 46] In a process for removing colloidal humic substances from raw water, the water is aerated and a water-soluble salt with a trivalent positive ion is added, the water is slowly agitated to effect the coagulation of the humic substance, and the air bubbles are enclosed in and securely bound to the flocs formed, which are then separated from the water by flotation. The raw water enters under pressure through a conduit 1, air being sucked in at 3 and a solution of a salt, e.g. aluminium sulphate, sprayed in at 4. Superfluous air escapes from a box 5. Alkali may be added-at 6, and aluminium sulphate and alkali at points 9 and 10 respectively. The water next passes to a flocculation tank 8, where platforms 29 rotating with a shaft 28. and spaced from the wall, alternate with fixed platforms'26 attached to the outer wall and having central openings 27. Both sets of platforms carry sets of pins 31, 32 respectively. The water flows generally upwardly, passing between adjacent platforms from the centre of the tank to the periphery and vice versa, 10 to 30 minutes being allowed for the water to pass through the tank. The water now intermingled with floes passes along a pipe 14 to the bottom of a flotation tank 17. Negatively-charged colloids such as animal glue or other protein substances; entirely saponified resin glue, soap solution, or sulphonated fatty and resin acids may be added to the water at some point between 14 and the bottom 15 of the flotation tank. In this tank the water during its upward flow is subjected to slow agitation between rotating arms 33 and fixed arms 34, the size of the flocs being thereby increased. A reduced pressure corresponding to a water column of 2.5 to 3 metres is maintained in the tank, causing the air dissolved in the water to be separated in the form of small bubbles on and in the humic flocs whereby these flocs are raised to the water surface, where they are removed by a scraper and a rotary suction nozzle 18. Purified water escapes through a plurality of openings 19 to a discharge tube 22. The tank 17 may be filled before starting through a conduit 24, and water for cleansing the tank and nozzle may be admitted through a conduit 25.

Title: Improvements relating to differential fluid pressure gauges
Inventor: PRICE STUART
IPC: G01L7/04
Filed: 1953-04-24
Abstract: 739,001. Pressure gauges. PAYNE & GRIFFITHS, Ltd. April 20, 1954 [April 24, 1953], No. 11327/53. Class 106 (2). A differential fluid pressure gauge comprises the combination of two oppositely-directed and spirally coiled Bourdon tubes b the inner ends of which are anchored, a pair of parallel rods f secured respectively to the outer ends of the Bourdon tubes, a rigid link g interconnecting the opposite ends of the rods, and mechanism operable through the medium of the link g for actuating an index finger. The link g may be secured to one rod f by a pivot-pin i and to the other rod f by an adjustable clamp j and have an adjustable coupling h in its length. Differences between pressures communicated to the tubes b through couplings e cause the link g to move a segmental rack p through a pin n and slot m and turn a pointer through a pinion q on its shaft engaging the rack p. The transmission from the link g to the rack p is varied in two modifications, in one of which the movement is magnified through a plurality of links.

Title: Transistor switching circuits
IPC: H03K17/041
Filed: 1957-04-08
Abstract: 800,593. Transistor switching circuits. NATIONAL CASH REGISTER CO. April 8, 1957 [April 11, 1956], No. 11366/57. Class 40 (6). In a circuit in which an input square pulse 31 causes an output current pulse 19 to pass through a load 23, the input pulse controls parallel current paths including a low power handling capacity transistor 10 and a high power transistor 11. The leading edge of the input pulse is passed through transistor 10 due to the better high-frequency response to form the output wave 18, but owing to the resistor 16 in the emitter circuit the wave 18 decays rapidly to a low value. The output waveform 17 from transistor 11 is initially at a small value but builds up through the pulse so that the combination of pulses 17, 18 give a substantial square pulse 19. The decay of the waveform 18 may be varied by adjusting the time constant of the circuit 16, 25. During the input pulse 31, capacitor 29 is charged so that when the pulse ceases the base potential is carried somewhat positive with respect to earth to sweep out minority carriers in the base region thereby terminating sharply the trailing edge of pulse 19.

Title: Improvements in thermostatic mixing valves
IPC: G05D23/185
Filed: 1925-05-01
Abstract: 253,317. British Arca Regulators, Ltd., and Lindsay, T. May 1, 1925. Valves controlled by pilot or relay valves.-In a thermostatic mixing-valve, a single valve element controls the hot and cold fluids, and is actuated by a relay controlled by a thermostat in the outlet chamber. The sliding valve V controls the passages 1, 2 for hot and cold water, and the mixture passes over a linear-expansion thermostat 19, 20, and thence to a mixing chamber. The valve spindle 8 is connected to a diaphragm 9 in a chamber 13, and is influenced by a spring 10. Liquid is supplied through a pipe 11 and valve 12 to the chamber 13, and thence through a pipe 14 to a jet 15. The liquid impinges against a lever 16 controlled by a spring 21 and pivoted at 17. The other end of the lever is connected to the rod 19, so that the outlet 15 is more or less obstructed by the lever 16, depending on the temperature in the chamber 4. The resulting pressure variations in the chamber 13 cause a movement of the diaphragm 9, and consequently of the valve V to adjust the proportions of hot and cold water. Specification 233,030, [Class 64 (ii), Heating systems &c.], is referred to.
