Title: Improvements in or relating to flexible oscillating bearings
IPC: F16F1/38
Filed: 1946-09-04
Abstract: 617,527. Resilient mountings. SILENTBLOC, Ltd., and HUTTON, P. C. Sept. 4, 1946, No. 26573. [Class 108 (iii)] Relates to flexible oscillating bearings comprising outer and inner members with a cylindrical annular space between them containing a bonded or compressed resilient bushing, the oscillating movement taking place through intermolecular deformation of the bushing. According to the invention an annular space is provided at one or both ends, between the inner surface of the outer member and the rubber bushing, of such dimensions that increasing axial loading moves the inner member and produces a radial swelling on the bushing which progressively fills the space. An inner externally-cylindrical member B is separated from an outer internally-cylindrical member A by a resilient bushing C of rubber or the like material. The inner member B and the bushing C project at each end beyond the end of the outer member A. The bushing C is initially of such dimensions that, when assembled between the members A, B, it is radially compressed, but the end portions C<SP>2</SP> of the bushing are of such diameter that, after assembly, they are not compressed and an annular space C<SP>3</SP> is left to accommodate any bulge on the bushing when under axial load. The actual dimensions of the annular space are determined by the maximum axial load expected. If desired, the annular space may be formed or augmented by chamfering the outer member internally. In an alternative construction, the rubber bushing C is not assembled in a compressed condition, but is simply bonded to the inner and outer members. In use the outer member A is fitted within an eye, while the inner member B is fitted tightly on a pin or bolt which clamps end members, constituting the side plates of a shackle, to the ends of the member B. The Provisional Specification states that the bushing may be bonded to one of the members A or B, only, and that the expansion space at the end of the mounting may be provided on the inner circumference of the bushing instead of on its outer periphery. Specification 437,114, [Group XXIV], is referred to.

Filed: 1959-08-04
Abstract: 852,804. Delivering measured quantities of liquids. RIKER LABORATORIES Inc. Aug. 4, 1959 [Sept. 2, 1958], No. 26601/59. Class 106(5) [Also in Group XXVIII] A valve for dispensing measured quantities of liquids, particularly aerosols, from a container 10 comprises a hollow plunger 20 slidable in a closure assembly 11 and divided into an upper discharge chamber 26 and a lower measuring chamber 22 by a wall 28, the chambers having ports 34, 32. In the normal position of the valve, the two ports are connected through a passage 40 formed by the sealing gaskets 12, 14, 16 but, on depressing the valve until the return spring 38 is solid, the port 32 communicates the measuring chamber 22 with the container so that it fills, ready for discharge through port 32, passage 40 and port 34 when the spring returns the valve to normal position. The valve is operated when the container is in an inverted position and the position of the port 32 close to the gasket 12 ensures that the last drops in the container can be expelled but, in a modification, the return spring is mounted within the container in a cage round which a dip tube can be fitted so that the valve can be used with the container in an upright position. In a further modification, the ports are each formed in a waisted portion of the valve plunger or transverse wall of resilient material being crimped between the two waists and a vertical groove is formed in the central gasket. The lower end of the plunger may be completed by a cup sealed to it in a selected position or screwed on so that the volume of the measuring chamber may be varied. For pressure-filling of the container, the spring 38 may be removed and the valve moved down until the port 34 is below the gasket 12.

Title: Improvements in methods of making tablets
IPC: A61K9/20
Filed: 1946-09-06
Abstract: Tablets, particularly medicinal tablets, having edges and a straight side are tumbled, e.g. in a tumbling barrel or like rotating vessel, until they nave acquired shapes approximating ellipsoids.  After removing the abrasion dust, the ellipsoids may be coated with the desired solution or composition, the resulting coating being continuous and of uniform thickness.  If the final protective coating is to be applied as a hot aqueous solution of a colloid such as gelatine, the ellipsoids may be first given a thin undercoating of an edible resin such as shellac.  The method may be applied to tablets formed of a granulation containing a plurality of vitamins and minerals and wherein the incompatible ingredients are isolated from each other by being incorporated in different beadlets having matrices of a gelable colloid.  In an example, vitamin A concentrate (fish liver oil) is emulsified with a hot aqueous solution of gelatine and corn syrup, the emulsion being solidified into sheets or beadlets by cooling, and the sheets if formed being ground to powder, iron ammonium citrate is dissolved in an aqueous solution of corn syrup, gelatin being subsequently added with heating, and the resulting solution being formed into beadlets; a dry granulation powder of vitamin C is also prepared; the three granular preparations are homogeneously mixed, the mixture being compressed into tablets and the tablets being tumbled and coated as previously described. Thiamine chloride (vitamin B), riboflavin (vitamin G), niacinamide, and viosterol (vitamin D) may be present in the vitamin A granules. Calcium pyrophosphate may also be added to the preparation.  Agar, pectin, or methyl cellulose may be used to form the matrices of the beadlets.

Title: Improvements in or relating to phosphors
Inventor: GRIMES JOHN HERBERT
IPC: G01T1/203
Filed: 1952-10-28
Abstract: Phosphors for use with a scintillation counter are prepared by mixing a dry polymerizable substance capable of yielding a transparent optically clear polymer, e.g. styrene, with a dry compound or compounds capable of scintillating in the presence of nuclear radiation, in an evacuable vessel, treating for the removal of dissolved gases, cooling to a low temperature under vacuum, sealing off and slowly raising the temperature, e.g. by 0.1 DEG  C. per hour, to effect polymerization over a period of several hundred hours. Suitable scintillation compounds are 1,1,4,4-tetraphenyl buta-1,3-diene, dinaphthyl, 1,1,4,4-tetra-m-tolyl buta-1,3-diene, terphenyl, or phenanthrene and a mixture of the first two is preferred.  A catalyst such as benzoyl peroxide may be included.  The components are preferably purified, e.g. by fractional distillation at low pressures or by chromatography with an alumina column.  In an example purified and dried 1,1,4,4-tetraphenyl buta-1,3-diene is dissolved in pure dry styrene at 40 DEG  C. and cooled.  Pure dry benzoyl peroxide is added and the mixture filtered into a clean dry tubular glass vessel where it is cooled and heated twice under reduced pressure to remove dissolved gases and finally sealed. Polymerization is carried out by heating from 35 DEG C. with a uniform increase of 0.12 DEG C. per hour for 294 hours.  The product is suitable for the production of a "light-pipe" for a photomultiplier tube.ALSO:1,1,4,4-Tetraphenyl buta-1,3-diene is prepared by reacting bromobenzene and magnesium in ether without heating to form C6H5.MgBr which is then reacted with diethyl succinate and the product acidified with acetic acid, steam distilled to remove diphenyl, and the residue filtered, dried and extracted with acetone to yield the glycol which is boiled in acetic acid to which has been added concentrated hydrochloric acid.  The product is filtered, washed, dried, recrystallized from toluene, extracted with animal charcoal and recrystallized from carbon tetrachloride.

Title: Improvements relating to liquid-slagging gas producers and blast-furnaces operating under pressure
Inventor: SECORD CAMPBELL HERBERT
IPC: C10J3/08
Filed: 1953-10-02
Abstract: 761,875. Discharging molten materials. MINISTER OF FUEL & POWER. Jan. 3, 1955 [Oct. 2, 1953], No. 27042/53. Classes 51 (1) and 51 (2). In discharging molten materials, e.g. metal and/or slag, from a pressure-operated furnace, e.g. a gas producer or blast furnace, the shaft 1 is connected by tapholes 9 and 10 with a steel cylinder 7 which tapers into a tube 8 extending through the shaft wall for a considerable height and containing molten lead or another metal having a specific gravity equal to or larger than that of the heaviest product to be discharged. The tube 8 may be insulated or provided with heating elements and the top of the tube may constitute a weir over which solidified particles of slag or iron fall into a pipe leading to ground level. If the products pass through the tube in a molten state, the molten lead may be replaced by molten iron, in which case the slag will rise therethrough but the iron produced will merely displace that in the hydrostatic seal formed by the contents of the tube 8 and the cylinder 7. Provision may be made for operating the furnace at reduced pressures, by providing open. ings at various heights in the tube 8. The space 6 surrounding the cylinder 7 may be water-cooled, producing high-pressure steam. The tapholes 9 and 10 are formed in graphite blocks incorporating cooling coils 13 by alternate operation of which slag and iron may be tapped alternately. The coils 13 may also carry an electric current, whereby the graphite blocks are heated by induction to melt the slag or iron in the particular taphole and start the flow. In a modified arrangement, Fig. 2 (not shown), the tapholes 9 and 10 are closed mechanically by hydraulically-operated plungers. By the provision of passages between the hydrostatic seal and the interior of the furnace, substances may be introduced into the furnace through the said seal.

Title: Improved procedure for preparing organolithium compounds
IPC: C07F1/02
Filed: 1963-07-09
Abstract: Organolithium compounds are prepared by reacting a lithium chloride sludge with an organosodium compound NaR, wherein R is an organic radical or with a mixture of sodium and RX wherein X is a halide radical.  Particularly R is an alkyl radical having 3 to 22 carbon atoms.  The lithium chloride sludge may be that obtained as a by-product in the preparation of organolithium compounds by the reaction of lithium with an organic chloride, and may contain unreacted lithium.  RX is preferably an alkyl chloride, and may contain branched chains, unsaturation or substituents where these do not affect the course of the reaction. The reactants may be used in stoichiometric proportions or, preferably, sodium is present in excess in relation to RX, LiCl is present in excess in relation to RX or NaR, e.g. in a molar proportion of up to 2: 1, and the molar ratio of Li Cl to Na may be from 0.2 to 5.0.  An inert liquid, e.g. mineral oils, refined diesel oils, hydrocarbons containing 4-14 carbon atoms and free from ethylenic unsaturation, amounting to at least 40% of the total volume of the reaction mixture may be employed as the reaction medium, to suspend the lithium chloride sludge and as the dispersing medium for the sodium metal which should have a particle size of less than 500 microns.  The sodium and lithium chloride sludge may be codispersed and RX added thereto, or the sodium dispersion and RX may be added to the sludge, the reaction mixture being cooled and maintained at ambient temperature or below for e.g. 2-10 hours. Reaction takes place under an inert gas, e.g. nitrogen or argon under anhydrous conditions, and the product is separated from precipitated sodium halide.
