The outer surface of the driver is roughened. The Provisional Specification states that the device may engage an internal screw-thread on the driving-spindle and that the member 2 may be of hexagonal &c. form for tightening with a spanner.
Patent GB-392827-A (GB)
Title: Drill stem and coupling therefor
IPC: F16L15/08
Filed: 1932-10-26
Abstract: 392,827. Pipe &c. couplings. MONTGOMERY, G. A., P.O. Box 5293, Young Street, Dallas, Texas, U.S.A. Oct. 26, 1932, No. 29995. [Class 99 (i).] In a coupling for drill stems &c., the pipe sections are formed with acutelytapered coarsely-threaded pins 7 adapted to engage with correspondingly threaded boxes 14, 15 on a coupling sleeve 2 which is formed with an internal flange 16 engaged by the end 8 of the pin, with or without the interposition of rings 18, to make fluidtight joints in advance of the threads 6, 11 of the pins 7 and boxes 14, 15. The end of the pipe section is thickened and its bore reduced until, near the end of the pipe, it is formed with parallel walls 5 terminating in a face 8 substantially thicker than the normal thickness of the pipe. The boxes of the ring 18 and flange 16 are equal to that of the walls 5, and the ring, which is of harder material than the pipe section, prevents the pin from being screwed in far enough to expand the box and compress the pins beyond their elastic limits, and also prevents creeping of the threads when the sleeve is heated in the well bore, thereby assuring a precise length of drill stem. The edges of the flange 16 are bevelled at 20 for the insertion of a tool to free the ring 18. The tips of the threads 6 are cut away leaving a passage for lubricant, escape of which is prevented by an outstanding packing-ring 9 in the pin engaging a tapering counterbore 21 in the box, the arrangement also counteracting side play between the pin and the box.

Abstract: 1359486 Coating with metals VANDERVELL PRODUCTS Ltd 17 June 1971 [20 June 1970 14 Oct 1970] 30041/70 and 48729/70 Headings C7F and C7X Apparatus for coating a pre-heated steel strip 9 comprises a crucible 1 of molten Al alloy having a nozzle 4, a container 3 of molten Pb having a valve 5, and atomizing means in the form of a series of N 2  jets 7. The Pb falls through the Al alloy and they are atomized together, forming a layer of co-deposited Al alloy and Pb droplets on the strip 9, which moves towards the rolling mill 10. The N 2  atmosphere is maintained right up to the mill 10 by means of a chamber 14 so that the droplets do not oxidize before compression by the rolls. Some Pb will dissolve in the Al alloy before atomization, and this is rejected on cooling to give a fine dispersion in the alloy matrix. In a modification, some Pb may be added to the alloy in the crucible 1 to control the amount of finely dispersed droplets of Pb in the matrix. The steel strip 9 may be precoated with Al or an Al alloy to improve adhesion.

Title: Improvements in or relating to gas heated instantaneous water heaters
Inventor: BYRNE PHILIP LOUIS
IPC: F24H9/20
Filed: 1955-10-21
Abstract: 832,191. Valves. MAIN WATER HEATERS Ltd. Oct. 19, 1956 [Oct. 21, 1955], No. 30108/55. Class 135. A gas-heated instantaneous water heater having mechanism for maintaining constant a predetermined ratio between the pressures of the gas and water supplied to the heater comprises a diaphragm or piston loaded by a spring and subjected to pressure of the gas supply in the opposite direction to said loading and movement of which diaphragm or piston controls a valve in the gas supply and the loading of which spring is varied by movement of a second diaphragm or piston subject to the pressure of the water supply. The diaphragm 27 is clamped to a cup-shaped extension 23 of a valve member 18 co-operating with a seat 14 and is loaded in a valve opening direction by a spring 34. The undersurface of the diaphragm 27 is subjected to the gas supply pressure from an inlet 13. An outlet 15 leads to the water heater. Water pressure is fed to the upper surface of a diaphragm 47 which coacts with the enlarged head 38 of a spindle 29, the lower end of the spindle having a recess 32 to accommodate the end of the spring 34. The loading of the spring 34 is thus varied according to the water pressure acting on the diaphragm 47. The diaphragm 47 is urged in an upwards direction by a spring 40 and the spindle 29 is provided with a head 30 which engages a plug 25 in threaded engagement with the cup-shaped extension 23 in a lostmotion connection such that should the water supply fail the diaphragm will flex upwards under the action of the spring 40 and close the valve.
Patent GB-190703-A (GB)
Title: Improvements in automatic cut-out devices for electrical circuits
IPC: G04F1/00
Filed: 1922-11-03
Abstract: 190,703. Soc. L. Drault et C. Raulot- Lapointe. Dec. 22, 1921, [Convention date]. Switches, quick-break; time-limit devices.-A readily-adjustable short-time switch comprises a knife blade 1 and an actuating lever 2 on the same pivot and connected together by a spring and forked operating member 6 carrying an external spring-mounted handle 5 and an internal loosely-mounted catch 23. To close the switch, the handle is first withdrawn from locking engagement with the slotted cover and then swung over to the vertical position. In this movement a pin on the operating lever 6 drives links 10, 12 to move a piston 14 freely along its cylinder 15, which is integral with the cover, against the action of springs 24, 25. At the end of the movement a lever 17, 18 freed from the link 10 drops through a hole 16 and takes up a position behind the end of the piston-rod to prevent the return of the piston. At the same time, the loose catch 23 engages the actuating member 2 so that, when the operating handle is returned, the lever 2 is carried with it, driving the blade into the closed position, where it is retained by the looking engagement of the handle with the cover. The return movement lifts the locking lever 17, 18 and the cylinder returns slowly under the action of the spring 24, 25 at a rate depending on the effective area of a variable port 27 which is covered by a rotatable throttle plate 28 having a circular groove the cross-section of which gradually increases, the larger end being open to the atmosphere. The final movement is rapid owing to the exposure of orifices 30, and the piston rod strikes a rod 19 which, through links 20, 21, 22, lifts the cable member 23 and frees the switch mechanism to produce a quick break under the action of a spring.
Patent GB-341414-A (GB)
Title: Milk products and the manufacture thereof
IPC: A23C11/06
Filed: 1929-10-05
Abstract: An artificial cream is prepared by intimately mixing milk or skimmed milk and a vegetable fat together with an emulsifying agent containing water soluble proteins from egg yolk, heating the product and homogenizing it at 70-90 DEG  C., preferably about 85 DEG  C. The fat used is preferably earth nut oil hardened until its melting point is about 32 DEG  C.  The emulsifying agent may consist of whole egg yolk, or a mixture of whole and dried yolk, or the water soluble protein-containing residue left after the extraction of the yolk with ether and chloroform.  The mixing may be effected at 40 DEG -65 DEG C. by spraying, preferably using a nozzle not greater than 0,4 mm. in diameter and pressures of 130 atmospheres or over, usually 180 atmospheres or over.  Preferably the fat is sprayed into the milk to which the emulsifying agent has been added.  Satisfactory mixing may also be obtained by using a mechanical mixer.  To obtain a product which will whip well, 20-45 per cent of fat may be added, an addition of 34-43 per cent giving usually the best results.  The homogenization is preferably carried out in two stages, the pressure in the first stage being over 100 atmospheres, a lower pressure being used in the second stage to reduce the viscosity of the product.  By varying this pressure the viscosity may be varied, lower pressures giving lower viscosities.  The mixture may be passed twice through a homogenizer, or through separate homogenizers or a two-valve homogenizer.  In a modification, a comparatively low pressure, e.g. 25 atmospheres, is used, the homogenization being repeated. The product on leaving the homogenizer is cooled, preferably to 2 DEG  C. for 24 hours and may then be used.  To increase its preservative properties, the product may be pasteurized by heating it in an air-tight container to about 70 DEG  C. for an hour, keeping it in the container at 40 DEG  C. for a day to allow spores present in the milk to develop, then heating as before to 70 DEG  C., keeping it for a day and heating it again.  The heating to 40 DEG  C. may be applied only for a portion of the 24 hours, e.g. 4-5 hours, the product being kept at atmospheric temperature for the remainder of the period.  A specific example of one method of preparing the product is given.  If buffer substances, e.g. phosphorus-containing salts, are added to the milk, the temperature at which homogenization is effected may be considerably less than 70 DEG  C.

Title: Apparatus for treating reactive synthetic plastics
IPC: B29B7/26
Filed: 1957-09-30
Abstract: <PICT:0831019/III/1> An apparatus for polymerizing or condensing the components of a synthetic resin consists of a vessel 1 provided with a cooling jacket 5, and an agitator 2 mounted on a central hollow spindle 3, which can be moved axially to close the outlet from the vessel at its base.  Cooling air is admitted through a pipe 9, which then enters a tube 10 and passes through the hollow spindle to an exit 11.  The hot reactants entering through pipes 6 and 7 are therefore cooled at the outer boundary and on the mixer, whereby adherent polymers at these surfaces are largely prevented.  The hollow spindle 10 is provided with a drill member 4 to cut through solid polymer at the exit, and then air entering pipe 9 forces out the reaction product.  The vessel may be washed out with one or more reactant components.  Preferably charging and discharge are controlled automatically and are metered.

Title: High-precision time switch
IPC: G04F3/06
Filed: 1954-10-25
Abstract: 763,546. Timed control of electric circuits. LANDIS & GYR AKT.-GES. Oct. 25, 1954 [Oct. 23, 1953], No. 30675/54. Class 118 (2). [Also in Group XXXVII] A device arranged to produce a time interval comprises a contact bridge K actuated by two synchronous motors M1, M2, through a differential gear, the time interval being variable by variation of the movement of the bridge between its end positions. With the parts in the position shown, the time interval is started by closing a push-button contact T to energize a relay A which closes a holding contact a1 and contacts a2, a3 which change over the supply to the motor M1 from D.C. to A.C. The motor starts and since motor M2 is braked by being connected to D.C., the planet wheel P is rotated to swing bridge K from contacts m2 to ml. This energizes a relay B to open a contact b and de-energize relay A so that motor M1 is braked by D.C. and to close a contact b4 to energize a slow-acting relay C. At the same time contacts b2, b3 in external circuits are operated. Relay C eventually closes a holding contact c4 and changes over contacts c1, c2 to connect the motor M2 to A.C., thereby returning contact K to its initial position where it bridges contacts m2 to energize a relay D having a contact d which is opened to de-energize relay C which falls off immediately because its contact c3 has disconnected a damping winding. The parts are thus reset ready for a further operation.

Abstract: 1,085,668. Fluid-pressure servomotor systems. K. FUJIWARA. July 21, 1965 [July 22, 1964 (2)], No.31058/65. Heading G3P. Also in Divisions F2 and F4] In a trap for discharging liquid from compressed gas lines, the liquid collects in a chamber C and on reaching a predetermined level raises a float 3 to unseat a pilot valve 4 thereby allowing the gas to pass via passage F to act on a piston 8 to cause the latter to unseat a ball valve 10 to vent a chamber J above a main valve member 15 via passage P. When chamber J is vented, the liquid, assisted by gas pressure on its free surface, unseats member 15 and is discharged via passages L, M, N. As the liquid level falls, the float reseats the pilot valve and the gas above piston 8 leaks to atmosphere via restriction G, thereby allowing spring 12 to raise the piston and reseat valve 10. Liquid continues to be discharged until none remains in chamber C, at which point gas flowing to the outlet L also passes via annular passage Q to develop a static pressure above member 15 which exceeds the dynamic pressure on the lower side thereof and thereby seats the member. In Fig. 2 (not shown), valve 10 is omitted and the stem (S) of piston (8) unseats the main valve against the action of a spring (25).
