Title: Improvements in mechanism for flanging and double seaming sheet metal receptacles
IPC: B21D51/32
Filed: 1922-02-27
Abstract: 199,432. Berry, G. W. Feb. 27, 1922. Seaming.-A cover is double seamed to an unflanged body, while rotating, by a manually operated device. The cover o and body o<2> are clamped against a rotating chuck b, rollers f and d engaging the edge o<1> of the cover and the body respectively. The lever i is then moved from the broken to the full line position, Fig. 2, thus moving the roller f axially to flange the cover and body at o<3>, Fig. 4. The movement of the handle is then reversed and this, owing to the engagement of a trigger j, causes the whole support c to turn about its pivot c<1> thus withdrawing the rollers f, d and bringing seaming and flattening rollers g, h into action successively. At the end of this operation a fixed projection c<3> releases the trigger and a spring e<3> returns the lever i and roller f to their original positions.

[Classes 7 (ii), 7 (iii), and 7 (vi).] During the power stroke of the piston a partial vacuum is produced which is in part relieved by air at atmospheric pressure admitted through a lift valve 16 ; at the end of this stroke mixture is drawn into the cylinder through the terminal port D, the air separating this mixture from the products of the previous combustion. On the upstroke the products with some of the air are driven out through the exhaust valve M; the mixture is ignited by the heat of compression. Regulating; valve gear.-The valve 16 is held on its seat by a spring 54, Fig. 4, bearing on a cup 52 on the valve stem and on the lower half 47 of a divided shell. The upper part 40 is fastened to a valve cage 26, which can be turned while the engine is running from a handle 75 and linkage 71, 63. The two parts of the shell have meeting faces in the form of cams ; by turning the cage 26 the upper shell part 40 is also turned and the lower part forced down to increase the loading effect of the spring 54. The lower edge of the valve cage has inclined faces, with which engage adjustable screws 83 on the connecting-rod to lift the cage; this has a cross pin 59 which strikes the cup 52 to take off the loading of the spring on the valve 16 and allow it to be lifted by the very small suction effect in the cylinder. Turning the cage by the handle 75 adjusts the time at which the screw 5 strikes the cage. A spring 34 holds the cage down. Vaporizers.-Mixture from the carburetter E passes first through a channel F formed on an unjacketed part of the cylinder cover, and then through a pipe H enclosed in the cylinder cooling jacket J.

Filed: 1927-03-03
Abstract: 291,524. Curtis, T. S. March 3, 1927. Pottery materials.-A ceramic body is composed of fibrous mullite crystals and a binder, the crystals being the product of firing a natural alumina silica bearing substance such as kyanite supplemented with additional alumina in splintery form. In the preferred method, kyanite of the fibrous variety is ground by known processes to a powder in which the maximum of long fibres is developed, the natural mineral being purified and concentrated up to a 90 to 95 per cent kyanite content. To this is added artificial corundum preferably obtained as' a by-product when alunite is roasted in the manufacture of potassium sulphate, which by-product contains approximately 88 per cent of alumina, 7 per cent silica and 4 per cent potash. Magnesium oxide is added to this by-product until the total alkaline earth content is equal to one half of the total alkali metal content, after which the mixture is melted in an electric furnace and allowed to cool slowlv. The ingots thus produced are sorted, crushed and ground, passed over a magnetic separator and then re-ground in a pebble mill. Finally weighed quantities of the kyanite and corundum products are mixed and re-ground with water in a pebble mill, after delivery from which the powdered mixture is ready for use as a material for producing pottery by any of the wellknown processes.

Apparatus for conveying and metering milk from cans 14 to a storage tank 2, e.g. mounted on a vehicle, comprises an intermediate container 1 into which the milk is drawn from can 14 through pipe 15 by a vacuum pump unit VI. When the milk in container 1 reaches a predetermined level, a switch 10 operated by float 8 operates hydraulically or pneumatically-actuated valves 5 and 6 to disconnect vacuum pump unit VI from container 1 and to connect container 1 to tank 2 through a meter 12. Tank 2 is connected to a second vacuum pump unit VII which acts to draw milk into tank 2 from container 1 and to draw more milk from can 14 into container 1. When can 14 is empty, milk is transferred from container 1 to tank 2 until float 8 has dropped to a predetermined level at which switch 10 closes valve 6 and operates valve 5 to connect vacuum pump unit VI to container 1 ready for emptying another can 14. When container 1 is to be completely emptied, a switch is operated to de-activate float 8 and activate float 9, valve 6 at the same time being set to a throttling position to reduce the flow and ensure accurate metering. When float 9 has dropped to a predetermined level, valve 6 is closed. Vacuum pump units VI and VII have associated liquid separators I and II. Float valves 7 prevent entry of milk into the vacuum lines. Non-return valve 13 acts to maintain , a vacuum in tank 2 when the vacuum pump is turned off. A non-return valve is provided at the lower end of pipe 11 in container 1.

Title: Improvements relating to electron multiplying electric discharge devices
IPC: H01J25/76
Filed: 1936-02-28
Abstract: 472,896. Electron multipliers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 28, 1936, No. 6098. Convention date, Feb. 28, 1935. [Classes 39 (i) and 40 (v)] Relates to apparatus for amplifying, detecting or generating high-frequency oscillations comprising an electron multiplier with several grids 2 ... 4 between the cathode 1 and the anode 5 and with a magnetic field in the spaces between the electrodes 1 ... 4 so that the electrons move in curved paths and strike the grids obliquely. Tuning means such as Lecher wire systems 7 are now provided each between two adjacent grids so that the potentials of these two grids vary in phase opposition, and the arrangement is such that the time of transit of the electrons across the space between the two grids is an odd integral multiple of one half-period of the oscillations. As the potential of the grid 2 increases, the number of electrons flowing to it and so of secondary electrons leaving it increases and this increased emission arrives at grid 3 at a time when its potential is high and thus increases the electrons flowing to and given off by the grid 3, the action being cumulative. The electrodes may be concentric cylinders or plane. The magnetic field may be coaxial to the cylinders, or at an angle thereto so that some electrons pass through the grids without striking them. The cathode 1 may be thermionic or photo-electric. The battery B<3> is connected to the tuned circuit at potential nodes or through chokes. In an amplifier, the control signals are applied to the magnetic field or to one grid such as 2 or between two grids and the output is taken from across two electrodes such as 4, 5. Specification 185,752, [Class 39 (i)], is referred to. The Specification as open to inspection under Sect. 91 comprises also drawings of a circuit for a reaction oscillator and of an amplifier with photo-electric cathode illuminated according to the input signals. This subject-matter does not appear in the Specification as accepted.
