Title: Improvements in spectacle and pince-nez cases
IPC: A45C11/04
Filed: 1938-10-11
Abstract: 517,257. Spectacle cases. LESSAR, H. L. Oct. 11, 1938, Nos. 29383 and 31305. [Class 97 (i)] A mount or frame is secured to the inside of the lid of a flat spectacle or pince-nez case, and carries means which grip the edge of a mirror laid against it. As shown, the case consists of a shallow sheet metal body 1 and a metal lid 2 hinged thereto at 3. From the lid 2 are pressed prongs 6 which engage slots in a metal mount 8 and are clinched upon one face thereof. A metal mirror 12 is held in position by tongues 9 or beaded edges on the mount. The mount may alternatively be of skeleton form, and may be made of rubber or resin. Reference is made to mirrors secured inside the lid of the case by soldering, rivets, or adhesive.

Title: Low-pressure casting
IPC: B22D18/08
Filed: 1972-06-23
Abstract: 1438644 Apparatus for low pressure die casting STERLING METALS Ltd 25 June 1973 [23 June 1972] 29426/72 Heading B3F [Also in Divisions F1 and G1] In a low pressure casting apparatus in which molten metal 3 is forced up a feed tube 5 into a mould by gas pressure in a space 7, the pressure in the space 7 is controlled so as to maintain the level of metal in the tube 5 above the level of the metal 3 in the pot 2 but below the top of the tube 5 between successive casting operations. The apparatus is provided with pressure-sensitive switches P 1 , P 2 , P 3  and P 4 , pressure governors R 1 , R 2 , R 3  and R 4 , non- return valves N 1  and N 2 , solenoid valves S 1 , S 2 , S 3 , S 4  and S 5 , flow controllers F 1 , F 2  and F 3  and valves or toggle switches T 1  and T 2 . Compressed air or inert gas is introduced into the apparatus through an inlet line 10. Between casting operations, the solenoid valve 5, is closed and the level of metal in the tube 5 is maintained at the required height by gas supplied to the space 7 through a line 11. The pressure-sensitive switch P 2  causes the valve S 2  to close when the required pressure has been reached in the space 7, and causes the valve S 2  to re-open if the pressure falls again, e.g. owing to leakage. To force molten metal up the tube 5 and into the mould, the valve S 1  is opened to allow gas to pass to the space 7 via a line 13. An increased pressure may then be applied to the metal in the mould by opening the valve T 1  to allow gas to flow through a line 14. Alternatively, the valve T 1  may be open during the filling of the mould and closed when the mould is full. After a predetermined time, the valve S 1  is closed and the valve S 4  opened to allow the gas in the space 7 to escape through a line 16. When the pressure has fallen sufriciently for the switch P 3  to be actuated, the valve S 3  is closed and the pressure necessary to maintain the metal in the tube S at the required height is maintained as described above. When the valve S 4  opens, the switch P 4  senses the temporary increase in pressure in the line 16 and starts a timer which is set to allow adequate time for depressurization of the mould before opening or unlocking the mould. The adjustment of the switches P 2  and P 3  and the flow controllers F 1 , F 2  and F 3  to compensate for the changes in pressure and rates of flow necessary as the level of the metal in the pot 2 falls may be effected by a single control.

Abstract: 1428392 Spray carburetters BRITISH LEYLAND (AUSTIN-MORRIS) Ltd 14 June 1973 [24 June 1972] 29712/72 Heading FIB A variable choke or constant depression carburetter has its fuel metering head varied in response to air density change arising from barometric pressure change by the application of a sub-ambient pressure to float chamber 21, the pressure in which is controlled by a depression control valve means 26 disposed between a source of sub-ambient pressure 17 and the float chamber, the valve means including a hermetically sealed capsule 42, responsive to barometric pressure, which applies a load via resilient means 44 to a diaphragm 27 defining a chamber 29 coupled by a fluid column 25 to the float chamber. A reduction in ambient pressure causes capsule 42 to expand, which tends to open valve 32 and communicate the float chamber to the constant depression region 17 via tubes 25, 34 reducing the pressure in the float chamber. Valve 36 opens simultaneously with valve 32 to allow air to flow via tubes 30, 39 to mix with the fuel vapour drawn from the float chamber, the circumferences of the valves being chosen in a ratio to give the requisite mixture strength. A valve assembly (not shown) is interposed in line 34 to seal off the constant depression region when the depression therein exceeds that at maximum rated air-flow. This valve assembly comprises a chamber closed by a spring-loaded diaphragm open to atmospheric pressure on one side and to the constant depression region depression on the other. The capsule may contain gas, e.g. nitrogen, so that compensation for density changes arising from both pressure and temperature changes can be made.

Convention date, Nov. 22, 1932. [Classes 120 (ii) and 120 (iii).] A method of fastening the end of the yarn or thread of a cop after winding the same in a threadwinding machine consists in fastening the yarn to the cop or cop tube and to the spindle by mechanical means. The thread guide 6, when the cop has been wound, may be caused to move rapidly from the head of the cop to the foot of the tube, laying on a few turns 21 of coarse pitch until it reaches the foot of the tube, where one or two turns 22 are made ; thence proceeding alongside the spindle or spindle hub where some more turns 25 are wound on. Alternatively, after completion of the cop, a few close turns 23 may be wound at the tip of the cone, either on the cop or cop tube or on a holder which may include a rubber ring 16, Fig. 22, or a spring loaded cap 18, Fig. 21, the yarn being then carried along the cop making a few steep turns 21, and in some cases a few close turns 24 also, before being led to the foot of the cop and to the spindle. The foot of the cop tube is provided with notches 12 or projections 14, Figs. 12, 14, or gripper devices, which may be merely a sharp groove 9 or a shallower groove with a rubber ring 15 therein, Fig. 16, to engage the yarns in advance of the point of anchorage to the spindle. The hub of the spindle may be provided with longitudinally extending notches to allow the coils of yarn thereon to be severed by inserting a knife therein. Alternatively, a reciprocable cutter, hand operated through rack and pinion mechanism, may be used to sever the coils, the cut portions being removed by a suction fan. A form of mechanism for affecting the motion of the thread guide is shown in Fig. 30. The reciprocation of the thread guide 6 is effected by cam C and rack and pinion mechanism 54, 55 weight-biassed at 52. The spindle 3 is driven by a friction wheel 41 operated by a shaft 42 through a clutch. Handwheels 43, 44 are provided whereby the spindle and the traverse mechanism may be manually operated to effect the additional windings after the cop has been wound, as previously set forth. Specifications 1398/13 and 332,936, [both in Class 120 (ii)], are referred to.

Title: Improvements in the electrolytic production of titanium
IPC: C25C3/28
Filed: 1953-10-29
Abstract: Oxygen-free titanium carbide particularly for use as an anode in the electrolytic production of titanium and preferably containing a small excess of carbon, is produced by melting a titanium oxide, such as titanium dioxide, and carbon in an arc furnace either (1) with a volatilizable flux of an alkali or alkaline earth metal chloride or fluoride and casting the product as the anode, or (2) by heating to 2000 DEG C. and pumping till production of carbon monoxide ceases or in a hydrogen atmosphere. The carbide produced by this second method is then ball-milled to pass through a screen of 325 mesh (Tyler standard), treated with dilute hydrochloric or sulphuric acid to dissolve any contaminating metal thereby picked up, washed, and dried.  It is then formed into a plastic mass by the addition of methyl cellulose and water, extruded through a die, and fired to effect sintering.  The addition of chloride or fluoride of an alkali or alkaline earth metal reduces the sintering temperature from 2400 DEG C. to 2000 DEG C.  If insufficient carbon is present to ensure that all the titanium oxide is reduced, small amounts of carbon, silicon, or chromium may be included in the mixture prior to sintering, these additions being eliminated during sintering by volatilization as low valency oxides.
