Title: Improvements relating to the mass production of articles by successive operations
IPC: A43D111/00
Filed: 1949-07-28
Abstract: 665,328. Boot-making machines. CALLES, I., and BUCATINSKY, J. July 28, 1949, No. 19906/49. Class 17 (i). [Also in Group XXX] A machine for mass producing footwear consists of a carriage or series of carriages each with a last thereon which is rotatable about an axis which is itself rotatable on the carriage between horizontal and vertical positions, the carriage or carriages being movable along a track in succession through a series of operating stations including a weltfixing station and a sole-fixing station, the welt-fixing means being on the carriage and being brought into operation at the appropriate station by means lying in its path, and the sole-fixing means being in the path of the last and operating by the last passing over it. The carriage h is propelled around the endless track a by an endless chain 9 passed around sprocket wheels 10 and 11, one of which is driven from a motor 16 through worm gearing and a gear box 15. Alternatively track a may be circular and carriage h is then secured to a rigid radial arm which is rotated about a vertical central shaft. A horizontal sleeve 23 extending outwardly from the carriage houses a shaft 22 having a pinion 21 on one end and a bevel gear 24 on the other which meshes with a similar bevel gear 25 on a shaft 26 mounted in a fitting 27 which is in turn pivotally mounted on an extension 28 of the shaft 22. The fitting 27 together with its shaft 26 is detachably secured in either vertical or horizontal position about the extension 28 by means of a spring loaded pin 32 engaging in one of a number of holes, e.g. four, in a disc 35 secured to sleeve 23. The remote end of shaft 26 carries a mandrel 29 to which a last 30, on which a shoe 31 is formed, is secured. At station b, Fig. 1, fitting 27 is fixed in the vertical position for cementing the lower part of the uppers and insole. The fitting then travels through chamber 44 for drying the cement to station c. At station c fitting 27 is turned to the horizontal position where the end of a welt 41 is applied. At this point a rack 1 fixed in the track a co-operates with pinion 21 to rotate shaft 26 and hence the shoe, winding on the welt. At station d a second rack 2 again rotates the shoe whilst a guide 3 also fixed to the track a engages an abutment 38', Fig. 3, on a two-armed lever 38 pivoted to a bracket 36 on the carriage h. This raises the two-armed lever, raising a counterweight 40 and depressing a roller 39 so that its weight bears against the welt to run round it and press it while the shoe rotates. At station e more cement is applied, fitting 27 being vertical and at station f fitting 27 is horizontal so that the shoe is pressed onto a sole 42 suitably supported. Finally, with fitting 27 vertical, the sole is pressed by rollers 4, 4' and 4" each mounted in a frame 6 pivoted at 7 to a stationary support and provided with a counterweight 8.

Title: Improvements in and relating to sealing-in machines for electric lamps and the like
IPC: H01J5/24
Filed: 1937-07-19
Abstract: 481,926. Thermionic valves. BRITISH THOMSON-HOUSTON CO., Ltd. July 19, 1937, No. 19978. Convention date, July 17, 1936. [Class 39 (i)] [Also in Group XI] In a sealing-in for electric lamps, thermionic valves and the like wherein the filament-supporting stems are carried in a series of heads mounted around the periphery of an intermittently rotating table and arranged to have a bulb deposited upon them from a bulb-feeding apparatus, a finger 15, Fig. 2, is pivotally mounted on a slider 17 adjacent to the path of the stem-holding heads and arranged so that in the retracted position of the slide the finger 15 is supported by a spring-pressed arm 34, the slide being moved forwardly at intervals to carry the finger over the position normally occupied by a portion of a stem 16, which then supports the finger or, alternatively, in the absence of a stem, the finger 15 drops and actuates means for discontinuing the feeding of a bulb to that head. In the example the finger 15 has an upwardly projecting rear end 41 which strikes a pivoted arm 42 when the finger drops, thereby swinging arm 42 outwardly and breaking the contact between an electric contact 43 on the arm 42 and a co-operating contact 44 on a stationary arm 47. The contacts 43, 44 are connected in the circuit of a relay 50, Fig. 5, which controls the excitation of a solenoid 60 provided with an armature 61. The armature 61 is connected by weighted links to a longitudinally slidable rod 68 connected by an arm 70 and rod 71 to a shoe 72 which co-operates with a roller 83 on the end of a lever 74 pivoted on a disc 73 mounted on the driving-shaft 14 of the machine. A tooth 77 on the lever 74 cooperates with a notch in a drum 75 which forms part of a sleeve 79 provided with a bevel gear 80 engaging a bevel gear 81 on the driving shaft 13 of the bulb-feeding apparatus. When a stem is not present in the sealing-head, the clutch-controlling means occupy the position shown, and the roller 83 on the lever 74 strikes the shoe 72 as the shaft 14 rotates, thereby lifting the tooth 77 out of the notch and disengaging the clutch. The intermittent forward movement of the slider 17 which carries the finger 15 above the path of the stem tubes is produced by a lever 19 connected to the slider 17 by a spring 20, the lever 19 being pivoted on a pin 22 in a bracket 23 and connected to a rod 26 which is connected to a rod 27, Fig. 5, by means not shown. The rod 27 is connected to a lever 28 which is rocked by a cam 30 on the shaft 14.

Title: Improvements in and relating to liquid level control devices applicable, e.g. to aircraft fuel tanks
Inventor: JR MORGAN LABRUT SWEENEY
IPC: G05D9/04
Filed: 1952-08-08
Abstract: 711,113. Fluid-pressure servomotor-control system. PARKER APPLIANCE CO. Aug. 8, 1952, No. 19987/52. Class, 135. [Also in Group XVII] A liquid level control device, e.g. for an aircraft fuel tank, comprises two inlet valves in series and closable individually by separate pilot valves each operable by a float, the floats being operable at the same or different levels. The inlet valves are housed in a body 10, Fig. 1, the first valve comprising a closure member 53 carried by a diaphragm 57 and being spring-urged to a seat 28. The second valve similarly comprises a closure member 54 carried by a diaphragm 57a and spring-urged to a seat 33. The two members are guided by a fixed pin 63 providing clearances 77, 78 through the diaphragms whereby the liquid flowing from inlet 20 to open both valves and flow through outlet 22 into the tank, also bleeds to the spring chambers 75, 76 at the rear of the diaphragms. Bores 79, 82 lead from the chambers 75, 76 respectively, to pipes 100, 114 extending to pilot valves 97, 111, Fig. 2, open to the tank interior and fixed at the top thereof. The pilot valves comprise closure members 90, 91, respectively, operable by floats 104, 118, set for different liquid levels. Thus, as the tank fills, float 104 will be raised to seat member 90 thus permitting pressure to build up in chamber 75 and ultimately balance the inlet pressure on the diaphragm, whereupon spring 59 seats member 53. Should this fail to happen and the liquid level continue to rise, float 118 will be raised to cause seating of member 54. If both floats are set for the same liquid level, the inlet valves will close substantially simultaneously.

Title: Improvements in the granulating and drying of fluid materials such as aqueous solutions, pastes and slurries
IPC: C01B17/02
Filed: 1961-06-02
Abstract: <PICT:0962265/C1/1> Solid granules are obtained from aqueous solutions, slurries and pastes by pumping the aqueous material through a nozzle 7 into a stream of gas, blown through pipe 4, whereby the aqueous material is pulverized by the gas stream, and passing the suspension up into a bed of preformed granules of the solid, smaller in size than that desired, maintained by the gas in circulating suspension in the frusto-conical hopper 2 and the cylinder 1 wherein the water evaporates from the aqueous material and the solid is deposited on the fluidized granules.  The enlarged granules are withdrawn through weir 8.  The aqueous material may be pulverized in hot air; or it may be preheated and then pulverized in cold air.  Nozzle 7 discharges the aqueous material in a converging-diverging passage formed by pipe 4 and the lower part of cone 2, where the air undergoes considerable acceleration.  The granules withdrawn through weir 8 are screened in order to separate the fines and the larger granules from the required product.  In Example 2, fines and larger crystals of potassium chloride are dissolved in water to form a 32% solution.  This solution is pulverized in a stream of air at a temperature of 200 DEG  C., and is carried up into a fluidized bed of potassium chloride crystals of 1 to 2 mm. size.  The crystals withdrawn through weir 8 are sieved in order to separate those having a width of 4 to 5 mm.  In Example 3, a 96% solution of ammonium nitrate at 175 DEG  C. is pulverized by a stream of cold air which carries it up into a fluidized bed of ammonium nitrate granules.  The resulting granules have a width of 2.5 to 4 mm.  The Specification also refers to the production of granules of nitrophosphoric fertilizer, and of urea.

Abstract: 1520082 Mixing apparatus BUSS AG 14 May 1976 20096/76 Heading B1C [Also in Division F4] In a method of treating a pasty substance by evaporation of diluent or solvent under reduced pressure an apparatus comprises a container 1 having heating jackets 7 and a horizontal shaft 6 through which heat exchange fluid is also passed, the ratio of the heating surfaces of the housing and shaft being in the range 60:40 to 52:48. The shaft carries at each end a simple agitator arm 22, and an agitator arm 21 having an end scraper 37 (see also Fig. 8, not shown). There are also agitator arms 20, 20' which have mixing and scraping paddles (30, 31, 32, Figs. 3-6, not shown) -arranged to move the material axially and radially. The paddles are oppositely angled so that during operation the materials are urged towards the ends of the container while during discharge the shaft rotation is reversed and they urge the materials towards the discharge port 4. The agitator arms are elliptical in crosssection and their hollow interiors are in communication with the interior of the shaft, the ends of which also carry scrapers 23. The entire surface of the container is thus scraped. There is a loose agitator 14 in the form of a tube (see Fig. 7, not shown) extending the length of the container which prevents balling and clumping and is driven by contact with the agitator arms.

Abstract: 515,924. Alternating-current motors. CHAMBERLAIN & HOOKHAM, Ltd., JAMES, S., and BOSSOM, R. P. July 7, 1938, No. 20107. [Class 35] Rotation in the wrong direction of a small synchronous motor is prevented by a pivoted pawl j having an abutment k at its free end cooperating with a pair of lateral projections c, d on a rotary member b driven by the rotor, the arrangement being such that when the rotor is rotating in the proper direction, one of the projections moves the pawl in one direction and the other can move it in the opposite direction, but on incorrect rotation, either projection is arrested by the abutment on the pawl. The projections are arranged in a diameter at unequal distances from the centre of the rotary member b and the projection d which is longer than the other moves the pawl aside in normal operation; if the pawl fails to fall back the return movement is effected by the action of the projection c on the surface m of the abutment k. The abutment k may be formed by the provision of an inclined groove in the rear face of the pawl. The member b is gear-driven from the rotor shaft or may be mounted on the shaft.

Title: Improvements in and relating to internal combustion engines
IPC: F01P9/02
Filed: 1925-08-11
Abstract: 261,084. Sharp, A. Aug. 11, 1925. Cylinders receiving liquid fuel.-In an engine wherein heated water is injected into the working cylinder after the completion of a two- or fourstroke internal combustion cycle, steam being thereby generated and expanded in the cylinder, separate exhaust pipes are used for the combustion products and for the steam. As shown in Fig. 1, a terminal exhaust port 20 leads to a chamber 19 from which lead the pipes 9, 12 for the combustion products and steam; a slide valve 9<a> controls the openings leading to the two pipes. On the valve rod 15 is arranged a second valve 14 controlling the admission of scavenging and charge air but this valve may be independently actuated. The water is heated in a coil 10 placed in the combustion-product exhaust pipe. Liquid fuel is injected though the nozzle 1 after an air charge has been compressed in the cylinder; at the end of the expansion stroke the products pass out through the pipe 9, some products remaining in the cylinder. These are compressed on the succeeding in-stroke and at or towards the end of this stroke; the water is injected into the cylinder and is converted into' steam by absorbing heat from the gases and cylinder walls. Overhead valves 1, 2, 4, 12, 14 and 34 may be. arranged as shown in Fig. 4 for the liquid fuel, water, combustion product exhaust, steam exhaust, scavenging air and starting air. The Provisional Specification states that water may also be injected during the internal-combustion cycle and that one steam cycle may alternate with two or more internal combustion cycles and viceversa.

Title: Improvements in valves for controlling supply of liquid under pressure
IPC: F15B13/06
Filed: 1943-12-03
Abstract: 584,373. Hydraulic apparatus. STRAUSSLER, N. Dec. 3, 1943, No. 20242. [Class 69 (ii)] A valve movable manually to operate selectively one of a number of liquid pressure motors, carries means whereby the liquid supply ceases at the end of the required operation. A valve b having pressure liquid supplied to its hollow bore c is rotated by a hand lever y to connect one of several ports e, f, g to a motor to be operated. The hand lever carries a pivoted member 3 which can be depressed against spring pressure, in each operative position of the valve b,'to actuate a switch 7, 9, 10 in the circuit of a motor driving the supply pump. On completion of movement of the liquid motor, the pressure rises within the valve and moves a spring-loaded piston t to break the said switch, thus stopping the pump. The hand lever y is normally held against a stop by a spring x opposing its rotation, and in this position the bore of the valve and all liquid motors are connected to a reservoir. Specifications 575,092 and 581,690, [both in Group XXXIII], are referred to.
