[Class 140.] Compound glass is made by coating glass sheets with a solution of a cellulose ester such as celluloid, removing the solvent by immersing the coated glass in a liquid, for example castor oil, which absorbs the solvent, for example as described in Specification 388,050, [Group III], removing the absorbing liquid, assembling the dried sheets in a liquid, preferably a high boiling point liquid, which is a slow-acting solvent or plasticizer for the cellulose ester such as benzyl alcohol or diethyl phthalate and adhering while immersed by slight mechanical pressure, for example 1 ounce per square inch. After removing the assembly from the bath and draining it may be matured at an elevated temperature, for example 95‹ C. for an hour. Before introducing the coated glass sheets into the assembling bath they may be warmed and the bath heated to 50-70‹ C.

Title: Improvements relating to the production of photographic gelatin relief images
IPC: G03C5/315
Filed: 1960-06-30
Abstract: 954,205. Photographic processes. GEVAERT PHOTO-PRODUCTEN N. V. June 30, 1960 [July 1,1959], No. 22981/60. Heading G2C. A photographic relief image is obtained by developing an exposed gelatins silver halide emulsion layer with a developer comprising a tanning developing agent, a quaternary ammonium or tertiary sulphonium compound as development accelerator and a softener for gelatin, and then removing the unhardened gelatin. The unhardened gelatin may be removed by washing, scouring with a rubber scraper, or by pressing against a receiving sheet such as of paper to which the gelatin is transferred. The tanning developer may be catechol or pyrogallol and the softener may be urea, formamide, ethylene chlorohydrin or sodium solicylate. In the examples, the development accelerator is ethylene dipyridinium dichloride,p-nitrobenzyl pyridinium chloride or dimethyl lauryl sulphonium methosulphate, and the developing solutions also contain sodium carbonate, potassium bromide and potassium ascorbic-borate or potassium sulphite. Other development accelerators specified are pyridinium salts wherein the N atom has a #-hydroxyethyl, methylcarbchydrazide, p-chlorobenzyl or benzimidazolyl-2-methyl substitutent or wherein two pyridinium groups are linked by their N atoms to trimethylene or pentamethylene chains, tetraethyl ammonium ethosulphate, trimethyl-lauryl ammonium chloride, N-methyl-N-p -nitrobenzyl piperidinium chloride, N-hexyl -N-p -nitrobenzyl morpholinium chloride, 1, 2, 3, -trimethyl-naphthimidazolium methosulphate, 1, 4-dimethyl-quinolinium methosulphate, trimethylene-di-iso-quinolinium dichloride and trimethylene-di-N, N<SP>1</SP>-p-nitrobenzyldipyrolidinium dichloride. One or more of the ingredients required may be incorporated into the photographic material. Thus the silver halide emulsion layer may contain urea and/or a tanning developer. This invention may be applied to the silver salt diffusion process wherein an exposed silver halide emulsion is developed according to the invention and pressed against a receiving sheet and the unhardened areas of the receiving sheet removed as above. Specifications 614,155, 804,076, 821,251, and 862,615 are referred to.

Abstract: 1,076,876. Gas heating process. LA FLEUR CORPORATION. May 31, 1965 [June 1, 1964], No. 23019/65. Heading F4S. Hot combustion gases at a high temperature (e.g. 3500‹ F.) are mixed with relatively cool combustion gases, and the gas mixture now at an intermediate temperature (e.g. 1700‹ F.) is passed through a heat exchanger 26 and over tubes 52 therein in which compressed helium or other gas is heated for use in a turbine power plant. The process is intended to prevent overheating of the tubes 52 and consequent damage thereto, by the combustion gases. In Fig. 3, the high temperature combustion gases are produced in a combustion chamber 38 fired by a burner 36. Relatively cool combustion gases from the heat exchanger 26 are passed by way of ducts 58 and 40, and blower 60 into a space around the combustion chamber 38 whereafter they are mixed in a chamber 46 with the high temperature burner gases. The combustion gas mixture then flows through duct 48 to the heat exchanger. Surplus combustion gases from the circuit, in quantity equal to the amount generated in the combustion chamber 38, are discharged through a duct 59 to the atmosphere either directly or alternatively through heat exchanger (32) (Fig. 2, not shown) in which the combustion air for the burner 36 is preheated. The heat exchanger 26 is described in Specification 1,076,875.

[Class 5(i)] A machine for cutting fodder and silage in which moving knives cooperate with fixed knives has a side delivery opening through which the cut material is ejected by centrifugal force. A hopper 12 is attached to a drum 13 mounted on a frame 14 and provided with a delivery opening 15. A series of stationary cutter blades 17 arranged in rows round the inner surface of the drum extends along the whole or part axial length of the drum, Each blade 17 is adjustably mounted in a holder 18 fixed to the drum. Coaxially mounted in the drum is a hollow shaft 19 carrying cutters 20 adapted to coact with the stationary cutters when the shaft is revolved.

In examples, racemic 1-(p-methoxybenzyl) - 2 - methyl - 1 : 2 : 3 : 4 : 5 : 6 : 7 : 8 - octahydroisoquinoline is resolved via its d-tartrate and then: (1) the (+)-isomer is stirred with hydrogen peroxide and then allowed to stand with manganese dioxide, the filtered reaction medium is saturated with common salt and extracted with chloroform, and the extract is concentrated and then heated with aqueous caustic potash; the resulting 2-(N-methyl-N-hydroxy - aminoethyl) - 41 - methoxy - 3 : 4 : 5 : 6-tetrahydrostilbene is distilled under reduced pressure, and the fraction distilling at 150-170 DEG  C./0.01 mm. is treated with oxalic acid in acetone to precipitate the oxalate of racemic 1 - (p - methoxybenzyl) - 2 - methyl - 1 : 2 : 3 : 4 : 5 : 6 : 7 : 8 - octahydroisoquinoline; (2) the (-)-isomer is similarly treated as far as the extraction with chloroform, ethyl acetate is added to the extract and the optically active N-oxide crystallizes and is filtered off, the mother liquor is concentrated and water is added to cause crystallization of the stilbene derivative, the second mother liquor is saturated with common salt and extracted with chloroform to give a further crop of the N-oxide, this is heated with aqueous caustic potash and the resulting stilbene derivative is treated as in (1).
