Title: A process for the manufacture of metal powders
Inventor: WEBB FRANK BALDOCK
IPC: B22F9/08
Filed: 1956-02-03
Abstract: 812,341. Graulating metals; copper alloys. BEAK & CO. Ltd., F. W. Oct. 8, 1956 [Feb. 3, 1956], No. 3490/56. Classes 82(1) and 82(2) In a process for the manufacture of metal powders a stream of molten metal is subjected to the action in succession of at least two jets of dissimilar fluids at least one of which is a liquid. Preferably the metal flows downwardly. In the form shown a molten metal 2 poured into a heated tundish 3 passes through a hole 4 and central opening into an annular and conical jet of fluid 9 from the jet body 7 and a like jet 12 from the jet body 10. The top jet may be gas (e.g. air) and the lower jet liquid (e.g. water or an oil) at a pressure of up to 100 lbs. per sq. in. and up to 2,000 lbs. per sq. in. respectively, the flow being up to 350 cu. ft. per min. and 30 to 35 Imperial gallons per min. The metal can be caused to flow horizontally or upwardly at an angle to the vertical, the two jets being appropriately disposed. Powders of copper or of alloys containing the following percentages by weight: Cu 89.1, 89.15, 89; Sn 10.68, 10.47,10.91; P0.09, 0.11, 0.07; Pb -, 0.06, -; O 0.03, 0.04, 0.02; may be produced by this process. Specification 553,672 and 719,047 are referred to.

Title: Improvements relating to the analysis of liquids
IPC: G01N35/08
Filed: 1958-02-03
Abstract: The automatic analyzing apparatus 10 includes an automatic analyzing means to which blood or other body fluid samples and industrial liquids are fed; a colorimeter 14 for effecting a colorimetric examination of the output of the analyzer means and a recording means 16 for recording the colorimetric examination of the output of said analyzer means.  The analyzer means includes a dialyzer 18 to which the liquid samples being analyzed and various liquid processing media are fed in predetermined proportions.  More specifically, <PICT:0855555/III/1> a proportioning pump 20 is utilized to feed a liquid sample, one or more primary processing media, depending upon the sample being tested, and air through the lines 22, 24 and 26 respectively of predetermined internal diameters, into the conduit or line 28. The air is introduced into the continuous stream of sample liquid in the conduit 28 before the primary processing liquid, which may be a diluent, is introduced into the sample liquid stream in the conduit.  As shown herein, a plurality of rollers are moved progressively lengthwise of the tubes and compress the flexible tubes 22, 24, 26, 30, 32 and 34 progressively along their lengths at spaced points against an underlying bed or platen, for pumping the fluids therethrough.  The samples may be introduced to the pump 20, and specifically to the line or conduit 22 thereof, from a suitable flask or flasks, or provision may be made for a suitable automatic intermittently rotatable sample feed device 36.  The pump 20 also feeds into line 54, through the tubes 30 and 32, a secondary processing medium and air, respectively, the pump being operative to break the secondary processing medium into air-separated segments which form the receiving solvent.  The receiving solvent, for the particular sample being analyzed, is fed through the line 54, as indicated by the arrow 72, to the diffusate compartment 68 of the dialyzer from whence it passes into the conduit 74.  In the dialyzer, the separable substance passes into the segments of the receiving solvent.  The receiving solvent, which is sent to the dialyzer compartment 68 by way of line 54, passes as a diffusate into the conduit 74. Simultaneously, the required reagent is pumped through the tube 34 into the conduit 76, and through the latter, as indicated by the arrow 78, into the conduit 74.  The mixture of the diffusate and the reagent then passes into a mixer coil 581.  From the mixer coil 581, the mixture may pass through the coil 80 of a heating bath 82, passing out of the bath into a conduit 84 which directs the mixture into a blending device 86, in which the air is eliminated and the liquid segments are consolidated.  From the blending device 86, the liquid flows through a colorimeter 14 which controls the operation of the recorder 16.  Specification 774,711 is referred to.

IPC: C08C19/12
Filed: 1952-02-12
Abstract: Chlorinated rubber which is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, esters and ketones is prepared from chlorinated rubber which is insoluble in said solvents by reacting it with an aqueous solution of an inorganic hypochlorite both dispersed in an organic chlorinating liquid and then separating the dissolved chlorinated rubber if desired.  The hypochlorite may be added in the form of sodium or potassium hypochlorite or in situ by passing chlorine into caustic soda, sodium carbonate, lime, calcium carbonate, magnesium carbonate, magnesium oxide, zinc oxide and aluminium hydroxide either in suspension or solution.  The organic solvent may be methylene chloride, chloroform, carbon tetrachloride, symmetrical dichloroethane, 1,1,2-trichloroethane, 1,1,1-trichloroethane, symmetrical tetrachloroethane, benzene, chlorobenzene, trichlorobenzene and nitrobenzene.  Precipitation of the soluble chlorinated rubber may be effected by the addition of water, methanol or alcohol or by the removal of the solvent. Specification 634,241 is referred to.

Title: Improvements relating to means for mounting sheets, slabs, panels and the like
IPC: E04B9/24
Filed: 1945-02-19
Abstract: 585,311. Mounting sheets, panels, slabs &c. MITCHELL, D. S. B., and MOSCATI, C. G. Feb. 19, 1945, No. 4145. [Class 20 (iv)] Sheets, panels, slabs and the like are mounted on inverted T-section beam strips by means of clips which are applied to the beam to clamp down on the edge of one sheet supported by one flange of the beam, means being provided to hold in abeyance the clamping action of the other half of the clip until a second sheet has been positioned in relation to the other flange of the beam strip, whereupon the full clamping action is brought into effect. The clip shown in Fig. 1 is formed with a U-shaped head portion 5 with inwardly inclined limbs 4, 4a whose recesses 7, 7a formed at different levels on the limbs engage the edges 6, 6a of the beam strip bulge 1 and cause the clip to lie at an angle with one foot portion 8 bearing down on the sheet 9 and the other foot portion 8a held above the second sheet 9a. When the sheet 9a is in position on the flange 3a of the strip the clip is forced down by hand so that the recess 7a comes out of engagement with the edge 6a and the foot portion 8a bears down upon the sheet 9a. The clamping action may be caused automatically by the positioning of the second sheet if the clip is formed as in Fig. 3 with an extension piece 11 against which the edge of the panel 9a bears and causes the recess 7a to disengage. This extension 11 and the foot 8a may be a single ply, double or looped portion. In a further modification the constructional means comprises a prop or strut of wire or metal, preferably of inverted L-section shaped to engage the ridge bulge on one side and temporrarily support the unclamped half of the clip on the other. One form of prop shown in Fig. 9 has two parallel base limbs 12a with hooked ends 12b which engage the ridge bulge and a back 12c which is supported on the flange 3a of the beam strip and has an abutment face 16 which supports the second half of the clip, until the prop is displaced by the positioning of the second sheet. Specification 573,581 is referred to.

A device for detecting knots in yarns comprises a pivotably mounted feeler element 18 adjustable to an initial position to define, with a fixed cooperating member 14 a gap just sufficient to allow a running yarn Y to pass therethrough, whereby each knot in the yarn causes the element 18 to rock and actuate a visual or aural graduated signalling arrangement which may be augmented by a counting device. Element 18 is kept in position by a spring 23, The member 14 is a hard ceramic or metallic eccentrically mounted roller. The counting device comprises a spring loaded pivotable catch arm 25, which constitutes an escapement mechanism release of which is effected by the passage of a knot through the gap. When the predetermined number of knots has been exceeded a cut-off knife may be brought into operation. A common resetting arrangement can be installed to act upon extension 28. In the path of the catch arm 25, are electrical contacts 35, 36, 37 which operate the signalling arrangement 29 and 31.
