Title: An improved process for the production of footwear
IPC: A43B13/12
Filed: 1947-12-23
Abstract: The shoe forming the subject of Specification 582,431 (which comprises a sole, or sole and heel, formed from a base material, such as felt, textile fabric or paper, impregnated with a plastic and an upper secured thereto by moulding) is made as follows: The upper is placed on a last which forms one member of a mould, and the base material and impregnating plastic is inserted into the other member of the mould, the surface of the base material facing the last and touching a portion of the upper that is turned over the last.  A margin of plastic, the function of which is to bond the base material to the upper, is then applied around the edges of the base material, and the two parts of the mould are pressed together and heated to polymerize the plastic.  The mould is then p  cooled, the pressure released, and the shoe removed from the mould.  The base material may be impregnated with the plastic before and/or after it is placed in the mould.  The impregnating plastic may be in the form of a sheet or powder or granules; if it is in sheet form it may be applied either to the last or to the other member of the mould.  When a raised wedge or platform heel is required, or an insole, these may be placed in the mould and incorporated with the shoe.  The press described in Specification 640,366 may be used.

Title: Improvements in and relating to the production of hydraulic cement
IPC: C04B7/32
Filed: 1927-12-16
Abstract: 303,639. Knibbs, N. V. S. Dec. 16, 1927. Cements, Portland and Roman.-A cement of the high alumina type is produced by subjecting a mixture of lime and bauxite or other highly aluminous material to the action of steam, preferably under pressure, to secure reaction between the raw materials, and then subjecting the resultant product to a higher temperature which is normally however below the melting- point. The proportions may vary from one to two parts of lime to three parts of bauxite. The bauxite is ground and mixed with either quick or hydrated lime. The steam treatment when carried out at a pressure of 100 lbs. per square inch may be completed in one hour. The heat treatment may be at a temperature between 1000‹ and 1400‹ C. With bauxite containing 50 per cent alumina and 20 per cent iron oxide, four hours heating at 1100‹ to 1150‹ C. is sufficient, or two hours at 1150‹ to 1200‹ C.

Title: Improvements in or relating to continuously variable change-speed gears
IPC: F16H15/22
Filed: 1938-11-24
Abstract: 521,804. Variable-speed friction gearing. L'ORANGE, P. Nov. 24, 1938, No. 34257. [Class 80 (ii)] In continuously-variable friction gearing of the kind in which an internal driven cone C is carried on an arm for bodily swinging movement about a driven shaft and transmits drive thereto through toothed wheels D. F, the tooth-reaction which exerts a load-responsive radial pressure Pr, pressing the driven cone C against a driving cone A, such radial pressure is supplemented by an axial pressure Pa, which is also proportional to the load and of such value that the resultant pressure R is perpendicular to the cone-surface whereby the independent speed-adjusting mechanism does not have to do any work against the force producing the traction pressure. Speedadjustment is effected by a governor which swings the arm E through a rod K, or either cone may be moved axially for this purpose. The load-responsive axial pressure Pa is produced by cam inclines H on the gear-wheel D, engaging rollers G on the cone C. the cam-angle being so chosen that the axial force Pa is equal to Pr tand where a is half the cone-angle. As shown several friction-gears may be grouped in parallel around aligned driving and driven shafts.

Title: Improvements in or relating to engine stop gear
IPC: F01L13/00
Filed: 1935-12-11
Abstract: 466,430. Valves. GARRETT, R. Dec. 11, 1935, No. 34307. [Class 135] [Also in Group XXVI] The fuel or steam supply to an internal-combustion engine, steam engine, or turbine respectively, is cut-off when the pressure of the lubricating-oil supply or cooling-oil or water system reaches a predetermined minimum. The control valve is opened normally against an adjustable resistance to start the engine. The pressure of the lubricating oil &c. is applied to the valve, permits the return of the manual control under the action of a spring, and maintains the valve open until it falls below a predetermined valve. The fuel or oil is controlled by a valve 13 coaxial with a piston rod 22 acted upon by a spring 16. The maximum lift of the valve 13 is controlled by a spindle 18. The piston 23 is acted on by the pressure fluid supplied by the pipe 25, and the cylinder 24 has a drain and is connected by a pipe 27 with the release cylinder 29 containing the piston 30. A fixed ratchet plate 33 has a pivot 34 for a bell-crank lever 35 one end of which is forked and engages beneath a piston-rod collar 37. The lever 35 carries a pawl which may engage teeth 40, 41 on the ratchet-plate 33, and a roller which engages a pivoted cam 43 having a pin-and-slot connection 44, 45 with the spindle 46 of the piston 30. A spring 48 resists movement of the lever out of its inoperative position, and moves the lever when the cam 43 is operated to withdraw the pawl. To set the apparatus, the valve is raised by the lever 35 against the resistance of the spring 16 until the pawl engages the tooth 41, and the lubricant pressure raises the piston 23 and passes through the pipe 27 and depresses the piston 30 to turn the cam and release the lever which returns to its inoperative position.

Title: A process for regenerating a cuprous ammonium salt solution
Inventor: BARRY MARTIN JOHN
IPC: C01G3/14
Filed: 1957-11-08
Abstract: <PICT:0841965/III/1> Spent cuprous ammonium salt solution containing absorbed CO, is regenerated by contacting the solution with an ammonia-containing gas at 25-150 DEG F. to absorb at least part of the NH3, stripping CO from the solution by the action of a stripping gas at 100-300 DEG F. and heating to 125-350 DEG F. to disassociate any retained CO.  The cuprous ammonium salt may be acetate, formate, carbonate, nitrate, or ethanolamine nitrate.  The NH3 contact may be at 5-50 psia, for 1 min.-1hr. using 25-100 moles NH3/10,000 gals. solution.  Stripping may be effected in a bubble cap tower or packed column at 5-50 psia. for 1 min.-1hr. with an NH3-containing gas containing 25-100 moles NH3/10,000 gals. solution.  The decomposition is effected at 5-50 psia., with 0.25-3hrs. residence, in the presence of O2-containing gas, e.g. air or O2, sufficient to maintain 5-50% of the copper in the cupric state, and NH3-containing gas in amount 25-100 moles NH3/10,000 gals. solution.  The CO-containing gas at 100 DEG F. and 2118 psig from 5 is contacted in bubble cap, or packed, tower 7 with a countercurrent of cuprous ammonium acetate solution at 32 DEG F. and 2158 psig.  The enriched solution is withdrawn at 13 through depressurizing valve 17 to absorption section A of tower 15 at 100 DEG F. and 6 psig.  The solution is withdrawn at 25 through heat exchanger 29 to raise the temperature to 158 DEG F. and returned at 31 to stripping section B, whence it is withdrawn at 37, and passed with make-up solution supplied at 39, to decomposition vessel 43, heated by superheated steam in coil 55.  The regenerated solution is withdrawn at 65 and returned through heat exchanger 29, cooler 69, refrigerator 73, and filter 75 to tower 7.  Air and NH3 are passed into vessel 43 through distributors 47, 51 and the resulting NH3 gas is fed through 35 into stripping section B, as stripping gas, and thence through 21 into absorption section A, whence the CO-containing gas is withdrawn at 19.

Abstract: 411,850. Speed indicators or signals. TAYLOR, W., and KAPELLA, Ltd., 104, Stoughton Street, Leicester. Dec. 9, 1932, Nos. 34925/32, 8076/33, and 36684/33. [Class 106 (iii).] When the speed of a vehicle exceeds a predetermined limit, a source of light is intermittently and automatically energized. An intermittent audible signal may also be given simultaneously or alternatively. In the apparatus shown in Fig. 1, the switch lever M is intermittently operated from the driving shaft G through a connection controlled by a centrifugal speed control device consisting of weights i<3> carried by springs i connected at one end to a collar H secured to the shaft and at the other end to a slidable bent non-rotatable collar J which allows the spring P to straighten the toggle kl, k<2> when a given speed is exceeded. The lower toggle link k2 is connected to the rocking lever M which is acted upon by a spring o so as normally to maintain closed the contacts m<1> in an alarm or signal circuit having an external contact n otherwise insulated from the apparatus. The upper toggle link k<1> is connected to a lever K which is rocked continuously by a roller k<5> on its other end engaging an eccentric Q driven by reduction gearing g<1>, g<2> from the shaft G. Below the predetermined speed, the toggle flexes as the shaft rocks, the lever M being unaffected. The slot l in the link L allows this movement. When the predetermined speed is exceeded, the toggle straightens and the lever Mis rocked by the lever K thereby alternately opening and closing the signal circuit. The apparatus is enclosed in a sealed casing consisting of an inner cylinder B secured by bolts a<1> to the base or bracket A, and an outer cylinder D held in position by a nut d screwed on a stem c<2> carrying a seal c<3>. Plungers s, s<1> may be provided to test whether the apparatus is in working order without breaking the seal. In one modification, the toggle linkwork is replaced by a two-position pivoted latch piece and in another a pivoted lever holds the roller on the rocking lever clear of the eccentric until a predetermined speed is attained and also holds the contact in the signal circuit apart. The apparatus may be associated with the ordinary vehicle lighting switch so as to ensure that the visible signal is in operation when the lamps are on at night and the audible signal by day.

Title: Improvements in or relating to the manufacture of barometric bellows and like corrugated tubes
Inventor: WOLLEY HERBERT WILLIAM GEORGE
IPC: B21D15/10
Filed: 1954-12-02
Abstract: 777,146. Making corrugated tubes for bellows; stamping. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 2, 1955 [Dec. 2, 1954], No. 34979/54. Classes 83 (2) and 83 (4). A process for forming a tube of uniform wall thickness into a corrugated tube of uniform wall thickness on the corrugated parts comprises forming the corrugations successively with the uniformed part of the tube unrestrained from moving axially towards the corrugations as they are formed. Apparatus comprises upper and lower corrugatting dies 12 and 11 respectively between which is placed a tube 13 of uniform thickness. A rubber ball 17 is positioned between a bolster 15 and a punch 16 inserted at opposite ends of the tube. In operation, the bolster is aligned with the first corrugation of the die and the punch operated to compresss the ball 17 and form the first corrugation. The punch is withdrawn and the die advanced to its next indexed position on a plate 28 and the operation repeated until all corrugations are formed. Apparatus for collapsing the corrugated tube to form a bellows element comprises a bolster 34 carrying four vertical guide pillars 35 and an insert piece 36. A connecting tube 37 passes through the bolster and the insert piece to a hollow mandrel 38 having radial holes 40 and carried in a punch head 45. The tube 37 connects with a fluid pressure regulating valve 42. In operation, the corrugated tube is placed over the mandrel and upper and lower sealing rings 43, 44 are positioned over the ends of the tube. Around the tube are placed a series of split shaping discs 49 which are held in position by the guides 35. With the valve 42 closed the mandrel is lowered into the seal 44 whereupon the valve and a bleed screw 48 are opened. When pressure fluid leaks from the screw it is closed and the mandrel is lowered to the position shown in Fig. 3b to form the bellows 50. In a modification for forming the initial corrugations the die has only two corrugations, one of which serves to locate the tube whilst the other is utilized to form the next corrugation, the die being split and advanced after the formation of each corrugation..
