Title: Thermally developable photographic material
IPC: G03C1/498
Filed: 1974-06-11
Abstract: 1447454 Heat-developable photographic materials FUJI PHOTO FILM CO Ltd 11 June 1974 [11 June 1973] 25941/74 Heading G2C Heat-developable photographic materials comprise a support containing in one or more layers (i) an organic silver salt e.g. silver behenate or laurate or silver benzotriazole, (ii) light-sensitive silver halide which, when exposed, catalyzes reduction of the organic silver salt to metallic silver on heating, (iii) a reducing agent, and (iv) a binder which may be omitted if (i) or (iii) can act as binder, wherein the silver halide is made simultaneously with and in the presence of the organic silver salt. The preparation is conducted by reacting a silver compound e.g. silver nitrate solution simultaneously with a halide of hydrogen, ammonium or a metal or an organic halogen compound and with a solution of the organic acid or a soluble salt thereof required to form the desired organic silver salt. In Examples, (1-3), solutions of silver nitrate and ammonium bromide or iodide or mixed bromide and iodide are added simultaneously to a toluene/water emulsion containing sodium laurate and lauric acid; (4), silver nitrate solution is added to a mixture of ammonium bromide solution and toleune/water emulsion containing lauric acid and sodium laurate; (5), a silver-ammonia complex solution and ammonium bromide solution are added simultaneously to a toluene/behenic acid/ nitric acid/water mixture; and (6), ammonium iodide solution and acidified silver nitrate solution are simultaneously added to benzotriazole in isopentanol. The materials have increased photographic speed compared with similar materials in which the silver halide and organic silver salt are not prepared together simultaneously.

Title: Improvements in refrigerating systems of the expansion type
IPC: F25B41/06
Filed: 1946-08-29
Abstract: 665,734. Refrigerating. GRAM, A. G., and BRODRENE GRAM AKTIESELSKABET. Aug. 29, 1946, No. 25975/46. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 29, 1946.] Class 29 In a compression refrigerating system in which the evaporator coil 13 communicates with a receptacle 10 connected to a compressor by a pipe 18, the riser pipe 15 from the coil discharges into a trough-shaped member 26, Fig. 1, within the receptacle and under a float 4 operating the admission valve for liquid refrigerant, the member 26 having a hole 27 so that the valve is actuated in accordance with the difference in liquid refrigerant discharged from the pipe 15 and passing through the hole 27. Because the float 4 is heavy enough to open the valve when no refrigerant is in the member 26, when the compressor stops, a valve 37 in the liquid supply line is automatically closed. In a modification, Fig. 2 (not shown), the liquid refrigerant passes to the evaporator through a pipe by-passing the receptacle 10 and the member 26 is replaced by a transverse wall in the receptacle having a bottom aperture adjustable from outside the receptacle. In a further modification (Fig. 3) a by-pass pipe 33 for the liquid refrigerant is again provided and the receptacle is divided by a wall 34 having an aperture 36 adjustable by a hand-wheel 28. The pipe 15 discharges into a funnel 16 feeding into a groove in an arm 5 supporting an open-topped vessel 4 having an orifice 9. The weight of the vessel 4 is not sufficient to open the valve until some refrigerant has been received from the pipe 15. At first starting the compressor it is thus necessary to open the valve by relaxing the valve stressing spring 19 by a screw 20 to allow ingress of refrigerant to the evaporator. The valve 37 is dispensed with. The pipe 18 contains a solenoid-actuated valve 45 to allow individual connection of a plurality of evaporator units to the compressor. Specification 659,051 is referred to. The Specification as open to inspection under Sect. 91 comprises also the subjectmatter of Specification 659,051 and also describes a modification of Fig. 1 in which i an additional partition is provided across the receptacle and has a bottom aperture. This subject-matter does not appear in the Specification as accepted.

Title: Novel unsaturated alcohols and a process for the manufacture thereof
IPC: C11B9/00
Filed: 1955-09-13
Abstract: The invention comprises both the dienic tertiary alcohols of the general formula <FORM:0786349/IV (b)/1> wherein R1 represents a C2-5 alkyl radical and R2 the methyl radical or R1 and R2 together represent the penta methylene radical, and the corresponding mono-olefinic alcohols wherein the above group >C=CH- in the 6, 7 position is replaced by the group >CH-CH2-.  Both classes of alcohols may be prepared by condensing a metal salt of acetylene with either an unsaturated ketone of the general formula <FORM:0786349/IV (b)/2> or the corresponding saturated ketone, hydrolysing the resulting acetylenic alcoholate and catalytically hydrogenating the liberated acetylenic carbinol at the triple bond in the presence of a catalyst which selectively catalyses the reduction of a triple bond to a double bond, e.g. a lead-inhibited palladium catalyst.  The products may be used in the preparation of oderiferous compositions and perfumes.  In examples: (1) 6-methyl-octen-(5)-one-(2) dissolved in diethyl ether is reacted with sodium acetylide in liquid ammonia; the resulting 3,7-dimethyl-nonen - (6) - yn - (1) - ol - (3) is isolated and catalytically hydrogenated to give 3,7-dimethyl-nonadien - (1,6) - ol - (3); likewise (2) 5-cyclohexylidene - pentanone - 2 is converted to 6-cyclohexylidene - (3) - methyl - hexyn - (1) - ol - (3) which is hydrogenated to 6-cyclohexylidene-3 - methyl - hexen - (1) - ol - (3); (3) 6,8 - di - methyl-nonen (5) one (2) is converted to 3,7,9-trimethyl - decen - (6) - yn - (1) - ol - (3) which is hydrogenated to 3,7,9-trimethyl-decadien-(1, 6)-ol - (3); (4) 6,8 - dimethyl - nonanone - (2), obtained by catalytic hydrogenation of the corresponding nonenone, is converted into 3,7,9-trimethyldecyn-(1)-ol-(3) which is hydrogenated to 3,7,9-trimethyl decen-(1)-ol-(3) and (5) 6-methyl octanone-(2) is converted to 3,7-dimethyl-nonyn-(1)-ol-(3) which is hydrogenated to 3,7-dimethyl nonen-(1)-ol-(3).  5-Cyclohexylpentanone-(2) is also specified as a ketonic reagent.  The ketonic starting materials may be prepared by reacting an alcohol <FORM:0786349/IV (b)/3> with an inorganic halogenating agent, condensing the resulting substituted primary allyl halide with an alkali-metal salt of an acetoacetic ester and saponifying and decarboxylating the resulting product and then catalytically hydrogenating when the saturated ketones are required, in which connection reference is made to Specification 785,086.
