Abstract: 855,044. Ball-and-ring mills. FISCHER A. G., G. Oct. 31, 1958 [Nov. 1, 1957], No. 35083/58. Class 59 A ball-and-ring grinding mill has a plurality of superimposed grinding sets, each comprising a rotatable member 3, 23, 24, 4, Fig. 3, driven by a shaft 1 and a non- rotatable member 25, 26, each of the members being grooved to form ball-races, the common axis of symmetry of the curved surfaces of the races being inclined towards the shaft axis, the rotary races being capable of axial movement and biased by spring or fluid pressure towards its associated non-rotating member. The shaft 1 is driven through a clutch mechanism 2. In the embodiment shown in Fig. 3, loading on the grinding sets is provided by cup-springs 15, the loading being adjustable through the nuts 14 on the screwed end of the shaft 1. The upper pair of non-rotary ball-races 25, are clamped between casing portions 27, 28, but the lower pair 26 are capable of sliding axially. The material to be ground is fed from a hopper 49 through an opening adjustable by means of a shutter 50, to a motor-driven bucket wheel 46 and thence to the grinding sets. Finely ground material is discharged by a centrifuging ring 11 towards an outlet 41 and is drawn up a pipe 29 by a discharge blower connected to the casing 37 of the annular outlet duct. A separator 35 fitted with adjustable tangential guide vanes 32 separates the heavier particles which fall through an annular gap 40 back into the grinding chamber. The separated material leaves by an outlet pipe 38 and passes to a centrifugal separator 20 from which air is drawn off upwardly and the ground material is deposited downwardly. In another embodiment the loading of the races is effected by fluid pressure, and in further embodiments the ground material is discharged from the bottom of the casing and the material to be ground may be fed separately from a grinding liquid, mixing taking place in the upper part of the casing. Fig. 5 shows a modified form of the mill of Fig. 3. An elastic packing 92 supports the lower non-rotating member 85 and a rubber sleeve 87 seals the grinding chamber 88 extending between the two non-rotating races 80, 85.

Patent GB-762161-A (GB)
Title: Production of terpolymers
IPC: C08F222/14
Filed: 1954-12-07
Abstract: 2 (6) Clear terpolymers of (a) a dialkyl fumarate and (b) two monomers selected from styrene, vinyl toluene, vinyl xylene, vinyl acetate and vinyl chloride, are prepared by free-radicalinitiated batch polymerization to at least 20 per cent conversion of a monomer mixture selected from the area that gives clear terpoly mers lying on and about (e.g. within 5 per cent of) the line joining the polymerization azeo trope composition of (a) and the first selected monomer to the polymerization azeotrope com position of (a) and the second selected monomer, as plotted upon an equilateral triangular co ordinate graph.  The polymerization azeotrope compositions are those which give interpoly mers containing the same relative proportions as the initial monomer mixtures.  The dialkyl fumarates specified are those of methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec.- butyl and t.-butyl radicals and mixtures thereof.  The polymerization may be carried out in mass, in suspension using suspending agents such as tricalcium phosphate or carboxymethylcellulose (e.g. with the formation of pearls), or in emul sion, e.g. using a redox-type catalyst and an emulsifying agent such as a salt of a sulphon ated long-chain alkyl aromatic compound or a condensation product of ethylene oxide and a long-chain aliphatic alcohol or mercaptan.  The term batch polymerization includes the con tinuous introduction of the three monomers in fixed proportions into a flow-type system, e.g. a series of reaction vessels.  Catalysts which may be used are benzoyl, di-t.-butyl, diacetyl and hydrogen peroxides; t.-butyl and cumene hydroperoxides; diethyl peroxycarbonate, potassium persulphate and perborate; a ,a 1-azodi-isobutyronitrile, p - bromobenzenediazonium fluoborate, N - nitroso - p - bromoacetanilide, azomethane, phenyldiazonium halides, diazo aminobenzene, p - bromobenzenediazonium hydroxide and p - tolyl diazoaminobenzene. Polymerization may also be initiated by heat alone or by the use of ultra-violet light, option ally in the presence of a photo-sensitizer.  In the example, various monomer mixtures are poly merized by heating in two or three stages.  The products are mixtures of interpolymers of varying proportions.

Title: Heat treatment of alloys
IPC: C22F1/10
Filed: 1973-07-25
Abstract: 1449273 Solution treating segregated cast alloys GENERAL ELECTRIC CO 25 July 1973 35422/73 Heading C7A Cast alloys containing segregated low-melting phases are solution treated by heating them initially to a temperature below the incipient melting temperature of the lowest melting point phase for a time sufficient to at least partially dissolve that phase in the matrix whereby the incipient melting temperature of the body is increased. The temperature is then progressively raised to continue dissolution of the low-melting phases while keeping it below the incipient melting temperature, until all of those phases have been dissolved. The casting is then cooled to ambient temperature. The treatment is applied particularly to alloys containing in percentage by wt:- Cr 8 - 15 Co 8 - 15 Ti 3.3 - 6 Al 2 - 5À5 W 0-7  Zr 0 - 0À1 Mo 2 - 5 B 0À005 - 0À03 Si 0 - 0À5 C 0À05 - 0À35 Mn 0 - 0À5 Fe 0 - 1 V 0-1  Ta 0 - 4À4 Nb 0 - 2 Hf 0 - 2 Ni balance In one preferred composition of restricted range Ti + Al is 7À5-9% and Mo + W/ 2  is 5-7%, with the Ti:Al weight ratio being greater than 1:1 but less than 3:1, while in another Al + Ti is at least 8À1%, Al + Ti + Ta + Nb is 11À7-12À5%, Ta + Nb is 3À6-4À4% and Mo + W is at least 8À5%.

Title: Improvements in or relating to apparatus for the administration of substances to living subjects
IPC: A61M16/10
Filed: 1955-12-12
Abstract: 798,561. Respiratory appliances. LEE, A. ST. J. Dec. 12, 1955 [Jan. 27, 1955], No. 35613/55. Class 81 (2). In order to relate the concentration of a substance supplied to a patient to the body condition, e.g. the carbon dioxide or anaesthetic content, samples of exhaled air are taken and the resultant measurement controls the supply of the substance. In the forced respiration apparatus shown in Fig. 1, oxygen and nitrous oxide through pipes 21, 20 respectively, are mixed at 24 and passed through a variable pressure regulator 30 to a manifold 10 in which a valve 50 is moved between seatings 11 and 13, to provide the respiration cycle. The valve is moved by air pressure admitted to a cylinder 60 under the control of a timing mechanism driven by a constant speed motor. When the valve 50 is against its upper seating 13 the gas mixture passes through the endotracheal tube 14 to the patient and when it is against the lower seating 11 the lungs are vented to atmosphere. A collapsible tube 44 in a closed chamber 45 is normally compressed by air admitted through pipe 85b, but the timing means causes the pressure to be released for a short interval at the end of each exhalation so that through oneway valves 46, 47 a sample of the air is sucked into tube 44 and passed to the CO2 analyser 42. This device gives a signal voltage, the magnitude of which depends on the proportion of CO2 present and this is compared in a circuit 120 with adjustable standard voltage obtained from source 109 to control servomotor 122 and adjust the pressure regulator 30 as necessary. In an application of the invention to an anaesthetic appliance (see Fig. 3, not shown), a gas analyser for determining the proportion of anaesthetic in the exhaled air is connected permanently in the breathing circuit but its output is only made effective to control the supply of gas through servomotors by a pressure-sensitive switch which responds to the change from exhalation to inhalation.

[Class 47 (i)] Relates to ar. rangements for loading a wheeled escape upon a fire engine or tender wherein the elements of a twopart fastening are brought into engagement and the escape is then tilted over, this action loading it on to the vehicle ; and consists in so arranging the fastening that the escape, when loaded, is automatically locked against linear movement in any direction relatively to the vehicle. As shown, the bar 5, which forms the part of the fastening on the vehicle, is flattened on one side 6, or is provided with spaced flats. The forked brackets 3 on the ladder 1 are each shaped as shown to provide a pocket 10 having a flat 11 about half the length of the flat 6 and a throat which is only just wider than the least thickness of the bar 5. In loading the ladder, the latter is moved, in an upright position, until the rounded parts 10 of the pockets engage the bar 5. The ladder is then tilted and lifted until its forward end engages the usual rest on the vehicle, when the flats 6 and 11 come into abutment. Disengagement of the brackets from the bar without reverse tilting movement of the ladder is then impossible, since the diameter of the bar is greater than the width of the throat of the pocket 10. In a modification, an ordinary bar-and-fork fastening is employed, and laterally-projecting pins are provided on the escape for co-operation with arcuate slotted brackets on the vehicle. Two pins may be provided on each side, cooperating with two arcuate slots, the chords of which are at right-angles.
