Title: Apparatus for measuring film thickness
IPC: G01N23/16
Filed: 1949-10-07
Abstract: 669,431. Measuring film thickness using radio activity. WINGFOOT CORPORATION. Oct. 7, 1949 [Oct. 28, 1948], No. 25820/49. Class 40 (iii). The thickness of a film is determined by passing it between a radio-active source and an ionization chamber the source being such that approximately half the radiation of the source is absorbed during its passage through the film. Various suitable radio-active substances are listed in the Specification but the carbon isotope C14 producing soft # radiations is described as particularly suitable. This substance in the form of a white powder, BaCO3, is mixed with a solution of cellulose nitrates in amyl acetate, spread over the bottom of a tray and allowed to dry. The circuit arrangement is shown in Fig. 3. A filtered rectified voltage is produced by a circuit of known type. If the voltage does not exceed a certain value as compared in a 6C5 with a comparison voltage developed across a tube of the VR75 type the 6C5 operates an anode relay 1 which in turn operates a heavier relay 2 to supply H.T. voltage to the ionization chamber and heater current to the series connected filaments of three electrometer valves through auto-feed back filters. Since the electrometer tube may be damaged if H.T. is applied before the filaments are hot, the output meter may be connected across a shunt in series with the filaments by means of a switch SW14 to indicate correct filament current. Push button switch SW4 is then closed and assuming that relay 1 does not come out due to excess H.T. voltage, relay 3 closes switches SW7 and SW6 to supply plate voltage to the electrometer tubes. A two bank, five-position switch SW15 alters the range of the meter for different film thicknesses and the bias voltage on the electrometer tubes VX41A. In a modification, Figs. 4, 5, 6 (not shown), two radiation sources may be used each in association with its own ionization tube the film being used to interrupt the radiation path to one of them and the outputs being compared in bridge circuits or a single source may feed two chambers a standard film being inserted in one of the radiation paths and the last film in the other, or finally two sources may be alternately presented to a single chamber by a rotating disc the output of the amplifier being separated by a commutator switch and compared in a bridge circuit.

Title: Improvements in and relating to gearings
IPC: F16H13/02
Filed: 1929-08-24
Abstract: 337,511. Fink, M. Aug. 24. 1929. Testing wear of metal on metal.-In means for testing the wear of, frictional gearing-elements, a. casing 3, which may be of glass for inspection of its contents, encloses the g e a ring- elements 1, 2 and may be exhausted or supplied at various pressures with inert or non-oxidizing or other gas through pipes 8, 9, one of which may be dispensed with, or through the hollow shafts. The apparatus may be used to test the differences in wear when the gearing is used in air and in a non-oxidizing gas such as carbon dioxide, it being stated that the wear of such gearing is mainly due to the production of oxides in the presence of oxygen adiabatically compressed in the vicinity of the gearing areas. Alternatively, the wear of different materials or protective coverings therefor may be tested in different atmospheres, for example smoky or acidladen air.

Title: Improvements in protein derivatives
Filed: 1953-09-24
Abstract: Protein derivatives are prepared by reacting a colloidal solution of a protein under alkaline conditions and at elevated temperature with an organic carboxylic or sulphonic acid ester, in which the -COO- or -SO3- group is directly joined to at least one aromatic ring containing an electronegative group in the o- or p-position, or with a carboxylic acid ester of an a :b - or b :g -olefinically unsaturated alcohol.  The specified proteins include gelatin, casein, soybean protein and blood albumin.  Suitable esters include esters of phenols containing electronegative groups ortho or para to the phenolic oxygen therein such as the formate, acetate, benzoate or benzene sulphonate of a suitable nitro- or chlorophenol; alkyl, aryl or aralky esters of aromatic acids having an o- or p-electronegative group in the acid radical such as ethyl chlorobenzoate, ethyl nitrobenzoate, alkylhydroxynaphthoate and phenyl salicylate; and such unsaturated alcohol esters as isopropenyl acetate, vinyl acetate, crotonyl acetate and styryl acetate.  The reaction is preferably carried out with an aqueous dispersion of the protein at a pH of 8 to 12.  The protein may be dispersed in water alone or in a water-solvent mixture, e.g. water-acetone, water-formamide or water-dioxane.  The protein may also be used in a non-aqueous solvent such as formamide.  A temperature of 30-70 DEG  C. is used. The reaction product is neutralized with acid and then set or coagulated and washed.  The products, especially those prepared from gelatin, are useful for dispersing and peptizing silver halides in photography (see Group XX).  In examples (1) an acetone solution of phenyl 1-hydroxy-2-naphthoate is reacted with an aqueous solution of casein, the temperature and pH being maintained at 60 DEG  C. and 10 respectively; (2)-(7) aqueous dispersions of gelatin are similarly reacted with o- or p-nitrophenyl acetate, isopropenyl acetate, methyl o-chlorobenzoate, p-nitrophenyl benzoate and phenyl salicylate. Specification 649,548 is referred to.
