Title: Improvements in ball or float valves
IPC: F16K31/26
Filed: 1924-08-06
Abstract: 237,104. Blakeborough, R. A., and Brotherton, C. Aug. 6, 1924. Valves controlled by pilot or relay valves.-A valve of the type comprising a circular casing a with a contracted outlet a<1> on which seats a tapered nose of a hollow plunger d working in an internal cylinder c within the valve casing, is operated by a float lever j controlling the action of the discharging liquid or of a separate liquid or of both, the pressure of which moves the plunger. The float lever operates a pilot valve controlling an opening in the plunger nose, the piston e of which valve closes triangular ports f<2> so preventing escape of the liquid leaking into the interior of the cylinder c and thereby forcing the plunger on to its seating. On the pilot valve opening the ports f<1> the static pressure inside the cylinder is reduced so raising the plunger which is assisted by the reaction of the discharging fluid. The pilot valve may be operated by a rack in the internal cylinder c geared externally with a toothed sector on the float lever j. The plunger may be formed with an annular portion cooperating with an auxiliary chamber in the internal cylinder c to which the liquid or an auxiliary operating liquid is supplied under the control of the float and in this case the pilot valve in the plunger may be omitted.

A process for the production of photographic layers which contain photographic additives incorporated therein in heterogeneous distribution which additives, in the form of a solution, are emulsified with the coating solution for the layer and the resulting mixture is applied on a support, wherein the additives are emulsified together with one or more compounds of the general formula:- in which R represents a substituted or unsubstituted alkyl or alkenyl group having 1 to 18 carbon atoms; R<SP>1</SP> represents a hydrogen atom or a substituted or unsubstituted alkyl or alkenyl group having 1 to 18 carbon atoms, and Q represents an alkyl group or substituted alkyl group having 1 to 9 carbon atoms or one of the groups COX or CH 2 COX in which X represents (1) a hydrogen atom or a hydroxy or an alkoxy group; (2) the group O-alkylene-[O-alkylene] -O-alkyl in which n represents O or a number from 1 to 10; (3) a substituted or unsubstituted amino group; (4) a substituted or unsubstituted hydrazino group; (5) a hydroxylamino group, or (6) a group -O-CH(CH 3 )-CH 2 -N(Z)-Y in which Y represents the group -CH 2 -CH(CH 3 )-OCO-CH 2 -CH(R)-COOH wherein R has the above indicated meaning and Z represents CH 3  or has the same meaning as Y. Preferably 0À1 to 10 parts by weight of the compound of the formula defined above are used together with 1 part by weight of the additive which is to be emulsified. The compound defined above is preferably added together with the additive which is to be emulsified to the casting composition dissolved in an organic solvent which may be methylenedichloride or ethyl acetate. The compound defined above together with the additive which is to be emulsified, as an aqueous alkaline solution optionally with a wetting agent, may be added to the acidified casting composition. The compounds defined above, many examples of which are given, do not cause flattening of the gradation and reduction in colour density and substantially prevent the increase in viscosity which many colour couplers containing -COOH or -5O 3  H groups cause during digestion, and prevent diffusion of stabilizers to adjacent layer (see Example 13). The additives may be U.V absorbers or white toners as exemplified in Examples 10 to 12. The other examples relate to the incorporation of colour couplers into photographic layers.

Title: Improvements in and relating to catalysts
Inventor: DOWDEN DENNIS ALBERT
IPC: B01J23/22
Filed: 1957-06-26
Abstract: A catalyst, stated to be suitable for the oxidation of aromatic hydrocarbons to oxygen-containing compounds and also for the oxidation of paraffins, olefines, aldehydes and ketones, is prepared by bringing a molten catalytic material comprising a vanadyl vanadate into contact with particles of a porous heat-resistant solid (preferably corundum, silica, silicon carbide or firebrick) and allowing the product to cool.  By "vanadyl vanadate" is meant a solid phase (or mixture of solid phases) each phase containing at least one of metal "M", i.e. Tl, Ag, K, Na, Li or Rb, together with oxides of vanadium, in which at least part of the vanadium atoms have a valency of 2-4. The M2O : V2O5 molar ratio in the vanadyl vanadate is 0,001 : 1 to 0,05 : 1.  The catalyst is preferably produced by one of the following methods: (i) V2O5 and an appropriate salt are fused together, the melt allowed to cool, remelted and support particles introduced, then withdrawn and allowed to drain, these steps being repeated until the activity of the catalyst indicates that the internal pore structure of the support is coated with vanadyl vanadate; (ii) V2O5 and p  an appropriate salt are fused together, support particles dipped in the melt and the latter allowed to cool, the appropriate salt in both (i) and (ii) being preferably potassium or thallium carbonate; (iii) the support is impregnated with soluble salts of V2O5 and the metal "M" and the impregnated support calcined. The catalyst is preferably tumbled before used to remove any vanadyl vanadate adhering to the external surface; it may be employed as closely graded particles of size 1/32 inch to under 3/64 inch to granules of size 1/8 inch to 3/16 inch.  The catalysts may be activated by carrying out the oxidation process for a few hours at a temperature above that which it is desired to employ ultimately, and thereafter decreasing the temperature to the desired value. Specification 828,812 is referred to.

Title: Improvements in and relating to die boxes for moulding clay tiles

Abstract: 647,144. Apparatus for moulding tiles. MALKIN TILES (BURSLEM), Ltd., and WILLDIGG, L. J. July 17, 1947, No. 19072. [Class 87 (ii)] Apparatus for moulding clay tiles comprises a rectangular die-box and top and bottom dies adapted to press the tile between them, and is characterized in that two opposite sides of the die-box are longer than the corresponding sides of the bottom die, and the top die is formed with a depending projection whose inside surface is shaped to the rounded or other contour required to be given to the tile, the projection on the top die entering a cavity in the die-box not occupied by the bottom die when the pressing takes place. The die-box consists of mild steel members 11 having hard steel liners 11a, and the bottom die 10 has an upwardlysloping lip or ramp 10b. The die 10 is raised into the position shown, and the box 11 charged with material from the sliding carrier of an automatically mechanically-controlled press of conventional type (not shown), which carrier moves from right to left in the drawing. A flexible flap or strip 14 supports the charge and prevents an undue amount of material from falling through the space 12 into a shoot underneath. After charging, the top die 13 descends, the projection 13a enters the space 12, pushing out the lodged dust on flap 14, and the tile is pressed. As the die 13 returns the bottom die 10 lifts the tile slightly, which is ejected by the forward re-charging motion of the carrier and the lifting action of the ramp 10b. The die-box may contain a number of bottom dies to co-operate with a corresponding number of dies on the press plunger.
