Title: Improvements in and relating to methods of producing rubber coverings
IPC: C09D107/00
Filed: 1932-03-10
Abstract: Benzene-rubber solutions are rendered capable of being sprayed by diluting them to the approximate viscosity of water by the addition of benzene, benzol, or the like, and adding protective colloids or emulsifying agents such as soaps, mineral or vegetable oils, or fats. According to an example, a mix consisting of 55 parts of rubber, 35 parts of zinc oxide, 3 parts of sulphur, 1,5 parts of an accelerator, and 5,5 parts of an oil is dissolved in 4 to 5 times its weight of a solvent.  Reference has been directed by the Comptroller to Specifications 29997/12,274,742, and 327,981, [all in Class 95, Paints &c.].ALSO:Benzene-rubber solutions are rendered capable of being sprayed by diluting them to the approximate viscosity of water by the addition of benzene, benzol or the like, and adding protective colloids or emulsifying substances, such as soaps, mineral or vegetable oils, or fats.

IPC: B23D37/06
Filed: 1921-03-05
Abstract: 176,664. Bateman, H. F. March 5, 1921. Broaching. - Relates to broaching-machines and consists in work-holding and tool-guiding attachments to enable long bars &c. to be finished on one or more faces. Fig. 1 (Provisional) shows a work-holding casing a which is attached to the broaching - machine. A number of bars e are held in the casing by screws k, the amount to be machined being determined by backing-pieces f. The broach b moves through the casing being guided by projections on the casing taking into grooves d. The bars abut against plates g at one end and are held in place by a hinged cover h at the other. In a modification, Figs. 1 and 2 (Complete), the work-holder 2 is open at the top and is secured to the machine by a flange 4 and boss 3. Bridge-pieces 5 bolted to the part 2 carry a longitudinal member grooved at 8 to guide the tool 7, the part 2 also being grooved at 8. As shown in Fig. 2, the bottom of the part 2 has a grooved bar 6 secured to it, a similar bar (not shown) being secured to the bridge-pieces 5. The work is held and positioned by screws 9, 10.

Title: Improvements in method and apparatus for handling finely divided materials
IPC: B65G53/06
Filed: 1947-03-15
Abstract: 627,424. Pneumatic conveyers. KENNEDY VAN SAUN MFG. & ENG. CORPORATION. March 15, 1947, No. 7247. Convention date, April 1, 1946. [Class 78 (i)] A method of handling powdered material comprises suspending the material in a gas stream passing through a main duct connecting a series of material redistribution points withdrawing a portion of the stream at each point ; separating the pulverised material from the gas stream of the withdrawn portion and passing the thus separated gas stream containing suspended dust back into the main dust at each redistribution point, and recycling the gas in the main duct together with any finely divided material suspended therein from a point beyond the series of redistribution points back to the intakes of the main duct, thereby preventing contamination of the atmosphere with the dust. As shown, a stream of powdered fuel and gas (e.g. air) is fed in by pipe 10 to cyclone separator 12, the fuel falling into bin 14 and the air escaping by pipe 50. The fuel from bin 14 passes through controlling valve 16 into the air stream in pipe 20 whence it is driven by fan 24 through main duct 26. The air is deflected by valves 40 in part through pipes 38 into cyclone separators 28, whence the fuel passes into bins 32 or via pipe 34 direct to a furnace and the separated air passes back via pipe 42 into main duct 26. The air carrying the remaining powdered fuel is passed round into cyclone separator 46, the fuel separating and falling through pipe 48 into bin 14 and the air passing off through pipe 50. If additional air is required to make up for losses its inlet into pipe 20 is controlled by valve 22 ; if there is any surplus air (from pipe 10) it is disposed of through pipe 54. Pipe 52 permits fuel-carrying air, after partial separation in separator 12, to be re-separated in separator 46.

Title: Improvements in or relating to thermoplastic sewing thread such as nylon and method of making same
IPC: D02G3/46
Filed: 1947-03-17
Abstract: Sewing thread composed of continuous filament yarns of thermoplastic material, preferably nylon, is formed by applying a twist of 3.455315/D turns to the component yarns and twisting them together with a finishing twist of 3.355315/D X Y turns, D being the denier of each yarn and Y the number of yarns in the thread, and subjecting the thread to an aqueous boil and the action of steam at an elevated temperature.  The thread may first be boiled in a relaxed condition and then treated to steam action, or may be subjected to steam pressure at a temperature of about 245 DEG  F., while rigidly holding the thread, and later boiled while in a relaxed condition; this may be followed by subjection to steam pressure of about 245 DEG  F.  The thread so formed will be resistant to shrinkage at temperatures up to about 245 DEG  F. and may be used for seaming stockings, corsets, men's clothing or leather goods.

Abstract: 164,510. Wates, F. S. S., and Major, J. L. March 12, 1920. Addition to 132,818. Morse and like code signal transmitting arrangements.-In a code signalling-transmitter as described in the parent Specification means are provided for sending out a call prior to the despatch of a message and the multiple - position switch takes the form of a plug 86 used with a selector-board 84, Fig. 3. Clockwork 44 drives the shaft 35 through a suitable clutch 70, 71, the commutator drum being fast on the shaft 35 and revolving five times as fast as the distributing drum on a shaft 80 driven by gearing 78, 79 from the shaft 35. Part of the surface of the distributing drum is divided into five segments. In the second and fourth positions current passes to the call sign drum 37, in the third and fifth to the message drum 34 while in the first position current does not flow, but the mechanism gathers speed. The selector board comprises a number of sets of holes 85, each set having a common contact 87 for numerals and separate contacts 88 for letters. A call followed by a message is despatched by plugging in and then depressing a handle 46 to wind up the clockwork, the handle returning to its first position during the sending. The shaft 45 of the spring motor 44 drives the collinear shaft 58 by means of a pawl and ratchet 67, 52, Fig. 2, a bell-crank lever 53 engaging a recess 56 on a disc 57 on the shaft 58 and preventing the drive taking place till a cam projection 60 in the driving train forces back the lever, which is then held by means of a pawl 64 and catch 63 till a projection 59 trips the pawl and allows the spring 62. to pull the lever back to the locking position.

Abstract: 807,561. Ammunition projectiles. M. L. AVIATION CO. Ltd Feb. 22, 1957 [March 12, 1956], No. 7677/56. Class 9(1) A rocket or similar projectile to be fired from a discharger is stabilized in flight by a fin structure the fins being in a collapsed state before discharge and each fin having a spring bias to cause it to swing about a radial axis to the extended position after discharge of the rocket. The rocket tail 1 carries four fins 4 pivoted on pins 5 which -are screwed into a venturi 3. The base 10 of each fin has a recess 11 housing a clockspring 12 one end of which bears against the fin and the other end 13 extends into a recess 14 in a sleeve 15 fitted over the roots of the fins. Thus the springs tend to move the fins 4 out of the folded position, but such movement is prevented by the barrel of the discharger. Each fin engages a lip 16 at the forward end of the tail 1. On leaving the discharger, the fins swing tangentially to the tail about the pins 5 until they abut shoulders 20 on the sleeve 15. Where they are held by spring catches 21. Catch 21 comprises a leaf spring 25 having a bent end 26 pressed into notch 27 by the fin 4. As the fin swings to the operative position, the catch 21 snaps into a recess 30 in the fin.
