Title: Tube support for x-ray irradiation apparatus
IPC: A61B6/00
Filed: 1952-08-22
Abstract: 707,202. X-ray apparatus. LlCENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Aug. 22, 1952 [Sept. 4, 1951], No. 21195/52. Class 98(1) [Also in Group VI] A tube support for X-ray irradiation apparatus comprising a tube holder and means for moving the tube holder around two axes, one of which is stationary and the other movable, which intersect each other at right-angles so as to direct the centre line of the tube holder constantly towards the point of intersection of the axes, is characterized by a primary guide determining a circular path around one of the axes, and by a secondary guide carrying the tube holder and adapted to move along the circular path, means being provided for oscillating the tube holder along the secondary guide with respect to the other axis. As shown in Fig. 9, a shaft driven by a motor 36 and journaled in a bracket 35 carries an arm 33 supporting a guide 23. An X-ray tube 18 is movable on the guide by means of a motor 31 mounted on the tube housing and driving a pinion engaging rack teeth on guide 23. The guide is so shaped that the X-ray tube moves in an arcuate path about an axis intersecting the axis of rotation of arm 33 at right-angles. The patient lies on a table 40 which is so adjusted that the region 16 to be treated lies at the intersection of the axes, towards which the X-ray beam is always directed. In use, arm 33 is rotated while the tube 18 moves to and fro on guide 23. Motor 31 may be reversed at each end of its travel by press-button switches 47, Fig. 10, on the tube housing, which engage abutments 48 fixed at each end of guide 23. Strips 51 may also be fixed to each end of guide 23. A lead strip 54 may be mounted on each of two strips 51 mounted at the ends of guide 23 to penetrate into the ray-defining cone at each end of its travel to cut off the X-ray beam. The number of movements of the tube on guide 23 during each revolution of arm 33 can be varied, and it is shown that when this number is small the region of maximum irradiation is well defined, and when the number is large the dosage falls off slowly with the distance from the region of maximum irradiation. To vary the distance of the tube from the area 16, arm 33 may be adjustable in length, and a number of interchangeable arms 23 of different curvature may be provided. The travel of the tube on arm 23 may be varied by attaching additional blocks to abutments 48, the strips 54 being also adjustable towards and away from strips 51. In an alternative construction, Fig. 13, the guide 23 is fixed at right angles to a rotatable ring 58 having teeth 59 engaging a pinion 60 driven by motor 36, the region 16 to be treated being at the centre of the ring. In either construction the guide 23 may be straight, and the tube mounted to tilt as it moves along the guide. The motors may be energized by electric cable, or replaced by a single motor with flexible cable drives to the parts of the apparatus, which may in this case be driven through variable speed gearing.

Abstract: 627,505. Pressure-relieving devices for fluids. POWER, R. F., and HYDRAULIC RECORDING INSTRUMENTS, Ltd. July 16, 1946, No. 21327. [Class 135] In a water meter, the increased volume of the water on freezing is accommodated by a pad 5 of expanded or cellular rubber located in the water space of the meter in such manner as to be prevented from rising due to its own buoyancy. As shown, the pad 5, which is impervious to water, fills the whole cross-section of an expansion chamber 4 which may be a separate member bolted to the meter casing. Where the pad is not a frictional fit in the chamber 4, a light helical spring may be interposed between it and the casing wall 6. In this case the pad may be constituted of a number of superposed expanded rubber discs. The pad may be of natural or synthetic rubber and is of adequate size to accommodate an increase of one-tenth of the total water space. Damage due to freezing of any water seeping into the gear-train casing 8 is prevented by a further pad 18 of expanded rubber, whilst a still further pad 22 protects the filter ring 21. The inlet 2 and the outlet 3 of the motor may have pipe connections as described in Specification 581,993. According to the Provisional Specification, the expanded rubber discs are retained in the expansion chamber by an open frame or displaceable wall. Some of the discs may be replaced by one or more compression springs.

Title: Improvements in or relating to centrifugal pumps
Inventor: MOSS NORMAN
IPC: F04D15/00
Filed: 1963-05-29
Abstract: 1,087,912. Centrifugal pumps. PLESSEY-UK Ltd. Aug.6, 1964 [May 29, 1963], No.21523/63. Heading F1C. In a centrifugal pump of the kind in which the delivery is controlled by limiting the admission of liquid to the pump to such an extent that the pump is only filled partly with liquid, thereby reducing the outlet pressure to that necessary to deliver liquid at the rate required, the pump inlet is so constructed as to impart to the incoming liquid a swirl about the impeller axis before the liquid reaches the impeller. In the centrifugal pump shown, inlet guide vanes 11, of variable angularity controlled by a servomotor 12, impart swirl to the entering liquid, preferably in the direction of rotation of the impeller. The liquid forms a free vortex, with its swirl velocity increasing as it moves radially inwards. Within the inner boundary 17 of the liquid vortex, a liquidfree air core forms and is kept at atmospheric pressure by means of a vent 15. The circumferential velocity of the liquid is somewhat less than that of the impeller eye when it enters the impeller but increases, due to contact with the impeller shroud 6, as the liquid approaches the impeller blades 4. In addition to imparting swirl to the liquid, the adjustable inlet guide vanes 11 are also used to control the effective inlet area for the purpose of varying the pump delivery. The rate of swirl therefore increases as the rate of admission decreases, whereby the tendency of the liquid annulus to disintegrate into droplets impinging individually on the impeller blades 4 is avoided. The tendency towards cavitation and erosion is thereby reduced. Preferably, a non-return valve 16 is provided to prevent escape of liquid through the vent 15 when the pump is stationary. The pump inlet duct may be a straight axial duct with the inlet guide vanes arranged to impart swirl to the axially-flowing liquid.

Title: Manufacture of a raw material for lacquers from resinous ethylene oxide derivatives of phenols and lacquers made therewith
IPC: C09D163/02
Filed: 1947-08-07
Abstract: A resinous ethylene oxide derivative of a phenol containing at least two ethylene oxide groups is heated in presence of a suitable solvent with dicyandiamide and an aldehyde condensation product containing etherified methylol groups.  The ethylene oxide resins are obtained by the action of epihalogenhydrins or dihalogenhydrins on polyhydric phenols in alkaline media. Suitable phenols are resorcinol, hydroquinone, 4,41 - dioxydiphenylmethane, 4,41-dioxydiphenylmethyl methane or 4,41 - dioxydiphenyldimethylmethane.  Resins from the last three mentioned compounds are known respectively as methane resin, methyl-methane resin and di-methyl methane resin.  The polynuclear phenols may be mixed with phenols such as 4,41-dioxydiphenylsulphone. Suitable aldehyde condensation products are ethers of methylol compounds of melamine, urea, dicyandiamide or phenol.  They may be replaced by the ingredients from which they are formed.  Acids or alkalies may be added to the reaction mixture.  Solvents mentioned are 2 - methylpentanediol(2.4); diacetone alcohol; toluene; o-dichlorobenzene; cyclohexanone, cyclohexanol or mixtures of these substances.  Additional solvents which may be employed in certain aspects of the invention are ethanol, propanol and butanol. Polyhydric phenols, e.g. any of those from which the ethylene oxide resins are formed may be added at any stage of the process.  The products are used for making lacquers particularly for application to metals for use in making cans for fruit and vegetables.  Plasticizers and colouring matters may be added.  In the examples: (1) dimethyl methane resin is dissolved in a mixture of cyclohexanol, cyclohexanone, o-dichlorbenzene and toluene, and heated with dicyandiamide.  A solution in butanol of hexamethylol melamine butyl ether and a little ammonia is added to the suspension and the mixture heated to form a clear solution which may be thinned, applied by usual coating methods and hardened by baking.  Metals may be adhesively united and lacquered in one operation; (2) is similar, using the butyl ether of methylol urea; (3) dimethylmethane resin, the cyclohexanol ether of a cresol-formaldehyde condensation product and dicyandiamide are heated together in cyclohexanol.  A number of other examples are given illustrating variations of the general process. Specifications 518,057, 579,698, 629,111 and 630,647 are referred to.
