Thin-walled hollow articles such as cups with integral handles are moulded from clay slip by pressing and vibrating the slip at low frequencies between non-rotating male and female formers 44, 34. The female former is raised and clay 18 (Fig. 1) present in the former is subjected to pressure and vibration and forced upwards into the space 20 between the two formers 16, 11, Fig. 1, thus forming the cup with handle. When the female former is lowered the slip solidifies and retains its shape. The female former, one of many on a rotating platform, is rotated one step and the cup is trimmed. Warm air is passed over the cup to dry it during the next 15 succeeding rotations and then is removed on the 16th rotation after the female former is opened. On the 17th rotation clay slip is placed in the former and on the 19th rotation the cup is again formed by pressing and vibration. In a modification the male former is lowered into the female former.

[Class 135.] A valve closure member E for stop valves and pressure-reducing valves is arranged in the fluid stream in such manner that the pressure in the inlet chamber A has no component in the direction of movement of the member E. The member E comprises a solid cylinder having a seating surface c which seats round an aperture D in a wall dividing the inlet chamber A from the outlet chamber B. The end a of the member E projecting past the stuffing- box F may be subject to atmospheric pressure or to outlet pressure led there by means of a pipe H. In another form, the cylinder E is hollow and open at both ends. In this case, the member E slides in the apertured dividing wall and one end of the valve seats against a part of the valve casing in the inlet chamber. As applied to a stop valve, the first form is used and the solid cylinder E is displaced by means of a lever and eccentric arrangement or by a nut and a screwed spindle. Fig. 5 shows a valve member according to the invention applied to a pressure-reducing valve. A movable member P, which may be a piston or a diaphragm, is subjected to the action of an adjustable resistance M and is connected to the valve member E. In another form, the valve member is connected to a piston or diaphragm subject one side or the other to a fluid which may or may not be the controlled fluid. The admission of fluid to the two sides of the piston or diaphragm may be controlled from a distance.

Abstract: 193,791. Michelin et Cie, and Michelin, E. E. Sept. 6, 1922. Punctures, apparatus for detecting.-In a device for giving audible warning, the explosion of a cartridge by a striker which ds released when the air pressure in a tyre is reduced below a predetermined value, the part acted on by the pressure in the tube, for example the diaphragm 12, Fig. 1, is arranged above the level of the beads of the outer jacket. The device is mounted on a plate 2 of metal, leather or rubber serving as a security-bolt. The outer cylinder 1 is held in place on the rim by a nut 6, and houses a plunger 17 and a bell 15 with a flared mouth which are pressed apart by a spring but are held against movement by a ring of balls engaging the conical mouth of the bell and a shoulder on the plunger, so long as the air pressure in the inner tube acting on the diaphragm 12 is above the limit. When pressure falls below the limit, the spring forces the bell outwards, allowing the ring of balls to increase in diameter and release the plunger. A cartridge 20 in a suitable holder is screwed on the end of the sleeve 1. To facilitate mounting the device a screwed cap with a chain attached is fitted instead of the cartridge.

Title: Improvements in and relating to the production of unsaturated compounds
Inventor: NOBLE MORAG LAUCHLAN
IPC: C07C69/54
Filed: 1950-10-05
Abstract: In a process for the production of substituted acrylic compounds an alkyl or aryl substituted acetylene is reacted with carbon monoxide and an aliphatic mono-alcohol at a temperature of from 180 DEG  to 220 DEG  C. and under 10-300 atmospheres gauge of carbon monoxide in the presence of a catalyst comprising the halide of a metal which forms a carbonyl or a complex of such a halide.  The invention also comprises butyl b -butylacrylate.  The reaction is preferably carried out in the presence of a solvent for the substituted acetylene which also dissolves or forms a soluble complex with the halide or dissolves the complex formed from the halide and triphenyl phosphine. Acetylene starting materials mentioned are methyl, ethyl, propyl and butyl, acetylenes especially those in which the alkyl substituent is normal and from these a - and b -methacrylates, ethacrylates, propacrylates and butacrylates respectively are prepared. Examples of suitable media mentioned are dimethyl formamide and acetonitrile. Examples of suitable catalysts are nickel fluoride, chloride, bromide and iodide and their complexes with triphenyl phosphine, e.g. [(C6H5)3P]2NiBr2. In examples: butyl methacrylate and butyl crotonate are obtained by fractionating the products resulting when methyl acetylene is dripped into a heated mixture of butanol, acetonitrile, butyl bromide, nickel bromide and hydroquinone in an atmosphere of carbon monoxide at elevated temperature and pressure (1); butyl a -butylacrylate and b -butylacrylate are similarly obtained using butyl acetylene instead of methyl acetylene (2) and ethyl a -butylacrylate and ethyl b -butylacrylate are obtained in a similar process using ethanol and butyl acetylene as starting materials (3).

Abstract: 439,317. Automatic control of electrical supply systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 23, 1934, No. 24336. Convention date, Aug. 23, 1933. [Class 38 (iv)] An electrical supply circuit is automatically regulated in accordance with variations above and below a predetermined value by a regulating relay which sets in operation a time delay relay the speed of which depends upon the extent of the variation and the direction upon the regulating relay so as to operate a further relay giving an upward or downward regulation. A load circuit 2 is connected to a supply circuit 1 by a transformer 3 regulated by switches actuated by a motor 4 rotatable in either direction from the position shown in which the leads are connected by a sector 22 on the motor shaft. Variation of the load circuit 2 above and below a predetermined value are transmitted by the transformer 5 to the regulating relay 6 thereby closing either contacts 8 and 9 or contacts 10. When the voltage rises, contacts 9 are first closed and complete a circuit from the transformer 5 through the resistance 14, sector 22 and windings of the operating element 13 of the disc 12, thereby moving it against spring 18 until the arm on the shaft of the disc engages contact 20 when a circuit is completed through switch box 23 and motor 4 thereby cutting out transformer windings. If the rise of voltage is sufficient, contacts 8 are also closed and part of the resistance 14 is cut out, thus increasing the speed of operation of the disc 12. On decrease of voltage contacts 10 are closed and current is supplied similarly to the operating element 15 of the time delay relay through a resistance 16 and a constant current resistance 17 such as a ferro-hydrogen lamp, thus moving the disc 12 in the opposite direction until the arm engages contact 21, so that motor 4 switches in further transformer windings.
