Abstract: 718,047. Surgical drainage apparatus. MIDGLEY, J. M. Feb. 5, 1953 [Feb. 15, 1952], No. 4069/52. Class 81(2) A flushing apparatus, primarily for cleansing the bladder, comprises a filling tube associated with an automatic syphon which empties the bladder each time it has been filled. Liquid from a supply tube 1 passes through a sediment trap 2 and drip feed tube 8 into a large bore tube 10 which feeds into a chamber 11 connected to the patient through a flexible tube 12. As the liquid level rises it rises similarly in a vertical tube 13, forming part of a syphon with a flexible tube 14 and discharge tube 15. The lower end 16 of the tube 15 is set about a quarter of an inch below the lower end of tube 13 and the topmost point of the tube 14 is placed slightly above the level of the patient's bladder. This ensures that the bladder will be completely filled before syphoning commences and that it will be completely emptied by the syphon before any refilling commences. The dimensions of the tubes 10 and 13 are such as to avoid the formation of air locks in the system.

Abstract: The compounds of formula I are prepared by N-acylation of a compound of formula II' by means of an acid of formula III'. In these formulae, R is a hydroxyl, NH2 or alkoxy group, R1 and R4 are each H or an alkyl, phenyl or phenylalkyl group, R2 is H or an organic substituent, R3 is H or a hydroxyl or alkyl group, m is 1, 2 or 3 and n is 0, 1 or 2. The acid of formula III' can be replaced by a functional derivative of the latter or, when n is 1, by an acrylic acid of formula R4CH=C(R1)-COOH. In the latter case, after the acylation, a thiol or thioacid R2SH is added to the double bond of the acryloyl residue. The compounds of formula I are therapeutically active in the treatment of blood hypertension (high blood pressure). <IMAGE>

Title: Improvements in Brake Mechanism for Railway and like Vehicles.
Inventor: GRESHAM FRANK JAMES
IPC: B61H9/00
Filed: 1917-03-22
Abstract: 112,549. Gresham, S. T., and Gresham, J. M., (Executors of Gresham, F. J.), and Kiernan, G. March 22, 1917. Fluid-pressure.-The steam brakes of a locomotive are automatically actuated simultaneously with the actuation of the automatic pressure or vacuum brakes, by means of a piston subjected on one side to the train-pipe pressure and on the other side to the pressure in a reservoir. The steam-brake valve may be fitted with a pilot valve adapted to be opened first so as to balance the pressures on the main valve and facilitate its opening. Fig. 1 shows a piston e operating in a cylinder a connected at b to the train-pipe, and at c to a reservoir fed from the train-pipe through a groove d. When train-pipe pressure is reduced, the piston e is raised and by means of a lever g and plunger i, cuts off the steam-brake connexion k from the exhaust m and opens the steam valve h. Release is effected when the train-pipe pressure is raised again to the reservoir pressure, causing the piston e to descend. The lever g may be actuated by hand. Fig. 2 shows a modification having a valve r which facilitates the release by allowing the train-pipe and reservoir pressures to equalize as soon as the recharging of the trainpipe for release begins. When train-pipe pressure is reduced, a supplementary valve u opens to cause a corresponding reduction above the piston c; and when the train-pipe is recharged, the valve r is moved to the position shown, thereby opening the train-pipe to the cylinder a by means of a groove t, and to the reservoir by an annular groove s and port q. The steam valve h is fitted with a pilot valve v which is first opened, thereby admitting steam through a passage x to a chamber y so as to balance the pressures on the valve h. Fig. 3 shows the valve r formed with an enlarged part and with the annular groove s communicating with the interior of the valve, the supplementary valve u being positively opened by contact with the cylinder a. In another form, the annular groove is dispensed with, communication with the reservoir being provided by means of a lift valve actuated by a cam-recess in the valve r. Fig. 4 shows modified means for actuating the steam valve by hand; the lever g is engaged by an arm 10 actuated by a rod 11 to which movement is communicated from a hand-wheel 12 through a spring 13. Fig. 4 shows also a modified arrangement of pilot valve v. In the case of a vacuum brake, one side of the piston e communicates directly with the train-pipe, and the other side through a non-return valve, the latter side being also connected to the reservoir.

Title: Dispersion or suspension of solid phase in liquid phase
IPC: B01F23/57
Filed: 1977-02-02
Abstract: 1515653 Mixing liquids and solids E H CUMPSTON 2 Feb 1977 [6 Feb 1976] 04197/77 Heading B1C A dispersion or suspension of a solid in a liquid is made by feeding the constituents continuously into a suitable mixer and operating it so that they first form a plastic phase in the mixer, and thereafter a more flowable phase capable of continuously flowing out of the mixer. This is achieved by varying the proportions of the materials and the power input to the mixer; when the object is achieved, the power input will vary in the same preparation as the material input. The constituents may be pre-mixed or introduced separately, with additives if desired, and the final product may be diluted with liquid in a further mixer. The invention is said to enable a product with a higher solid/liquid ratio than hitherto to be produced. Examples relate to suspensions of bentonite, kaolin and other clays, carbon black, lead chromate, calcium carbonate and titanium dioxide. Suitable apparatus has a coaxial cylindrical rotor and stator as disclosed in Specifications 1407712 and 1407711.

Title: Improved process and apparatus for obtaining volatile fractions from crude mineral oils and the like
Filed: 1920-02-12
Abstract: 164,800. Engelke, E. F. Feb. 12, 1920. Mineral oils.-In distilling crude mineral oils and other hydrocarbon oils and residues, coal tar, &c. to obtain increased yields of volatile fractions and to obtain residues of lower specific gravity and viscosity, the heated oils are repeatedly treated with gases containing free hydrogen such as natural gas, oil gas, gases obtained during the distillation of hydrocarbons, water-gas, blast-furnace gas, &c. Superheated steam may be added to the gas. The oil is passed through a heat exchanger in which it is heated by the residues, and through a series of pipes heated by a furnace. The heated oil is led by a pipe 3 to an injector i from which it is sprayed by heated hydrogen - containing gas supplied through a pipe 12, through nozzles N into an evaporator E. The unvolatilized oil drops into longitudinal trays T on which it is again treated with heated gas supplied by a pipe 13 to perforated pipes Q. The oil flows 'from the trays through pipes P into the base of the still where it is again treated with heated gas supplied through perforated pipes S. The residue is withdrawn through an outlet 1. The vapours pass from a dome D to a dephlegmator for separation of the heavier fractions and to a condenser forseparation of the lighter fractions. The gases may be heated and returned to the apparatus. The evaporator E may be provided with several series of trays, and may be under reduced pressure. The residual oils from the evaporator may be heated to a higher temperature and passed through a second evaporator.
