Title: Improvements in or relating to photographic processing apparatus
IPC: G03D3/13
Filed: 1950-12-08
Abstract: 693,644. Processing photographic films. ASTOR, C. W. R. Dec. 7, 1951 [Dec. 8, 1950], No. 30115/50. Class 98 (ii) Photographic film processing apparatus comprises a tank for containing liquid, and a roller mechanism and mounting therefor located within the tank, said roller mechanism being adapted to draw photographic strip material through the tank and having a driving spindle, one end of which projects outside the tank and carries a gear-wheel which is adapted to engage with a fixed driving gear outside the tank, the roller mechanism and its mounting being bodily removable from and replaceable in the tank without the necessity for fastening or unfastening any screws or the like. The apparatus shown comprises a tank 10 in which two plates 11, spaced apart by members 12, 13, are removably mounted. The upper portion 11a of each plate is enlarged and the lower edge thereof engages in a slot 10a in the top of the tank to prevent lateral movement of the plates. Spindles 16, 17, Fig. 3, carrying rollers 14 and 15, pass through the plates 11 and carry gears which mesh with a gear 26. Spindle 16 projects through a slot in the tank and also carries a gear 20 which is adapted to engage a fixed driving-gear (not shown). Accommodated in slots 11b of each plate are spindles carrying rollers 21 disposed on each side of the rollers 14, 15 and pressed into engagement therewith by elastic bands entrained around pulleys 25 mounted at each end of each of the spindles carrying the rollers 21. Thus when the driving gear is rotated the central rollers 14, 15 are rotated in one sense and the rollers 21 in the opposite sense so that a film can be fed through the liquid in the tank. Grooves 11c in each plate serve as film guides.

Abstract: Synthetic crystalline zeolite L of composition <FORM:1023283/C1/1> where M is an exchangeable ion from Groups I, II or III of the Periodic Table, H+ or NH4+ and n is the valency of M, and having given X-ray pattern, is prepared in its Na/K form by forming a mixture of composition: K2O/(K2O + Na2O) from 0.33 to 1 (K2O + Na2O)/SiO2 from 0.35 to 0.5 SiO2/Al2O3 from 10 to 28 H2O/(K2O + Na2O) from 15-41 e.g. by dissolving KwNa aluminate, activated Al2O3, gamma Al2O3 or Al(OH)3, in KOH and/or NaOH, and mixing with K or Na silicate, silica gel, silicic acid, silica sol, or amorphous silica. The mixture is heated in a closed container at 100-150 DEG  C. until the zeolite crystallizes, and the crystals are washed until the effluent pH is 9-12.  The Na/K ions may then be at least partially ion-exchanged with Na using NaCl or NaOH solution, or with Ba, Ca, Ce, Li, Mg, Sr, Zn or NH4, using solutions of the chlorides, sulphates, or nitrates having a pH of 5-12. The zeolite may be used as an adsorbent after activation by partial dehydration at 350 DEG C. under atmospheric or reduced pressure, or at room temperature under vacuum.  It adsorbs molecules smaller than 9.1 <\>rA, those that are polar, polarizable or unsaturated being adsorbed more readily.ALSO:Zeolite L of composition <FORM:1023283/B1-B2/1> where M is an exchangeable ion from Group I, II or III of the Periodic Table, H+ or NH+, and n is the valency of M, is used to remove water from air streams and to recover traces of ethylene, acetylene, propylene and butene from gas streams; e.g. the k form of the zeolite is used to dry air at 25  DEG C. containing water at a partial pressure of 0,1 mm.

Title: Improvements in or relating to diagnostic compositions
Inventor: BRADLEY WILLIAM
IPC: C12Q1/54
Filed: 1961-08-28
Abstract: A composition for detecting glucose in urine comprises glucose oxidase, an oxidation-catalyst, and an indicator which is oxidized by hydrogen peroxide, changes colour on oxidation and has the general formula AR-X-AR wherein Ar is a phenyl group which may have one or more hydroxy and methoxy substituents and X is the radical -(CH=CH)m-CH=(N-N)n=CH-(CH=CH)p-in which m, n and p are each each to 0 or to 1, and a catalyst for causing the oxidation of the indicator by hydrogen peroxide.  The glucose oxidase converts glucose to gluoconic acid in the presence of atmospheric oxygen and at the same time forms hydrogen peroxide. Suitable indicators are 4,41-dihydroxystilbene, 4,41-dihydroxybenzaldazine, vanillinazine, 3,31,5,51-tetramethoxy-4, 41-dihydroxybenzaldazine, 3,31-dimethoxy-4,41-dihydroxystilbene, and bis-gamma(4-hydroxyphenyl)acroleinazine.  Splinters, sticks or strips of wood, paper or cellulose acetate may be impregnated with the composition; or the composition may be applied to glass, metal or plastic using gelatin as adhesive.  Such test pieces will change colour when moistened with a glucose-containing liquid. Suitable catalysts are peroxidase, catalase, blood, hemin, uroferriporphrin chloride, and a mixture of potassium iodide and sodium molybdate.  A buffer composition, e.g. citric acid/sodium citrate may be added to the test composition in order to keep the pH of the reactants at a predetermined value.  Gelatine, dog plasma, bovine albumin, egg albumin and casein may be incorporated in the compositions. Specification 808,742 is referred to.
