Glucose.-The hydrolysis of cellulosic material for producing a wort adapted for butyric fermentation to obtain alcohol and aliphatic acids, consists in subjecting sawdust to a preliminary treatment with sulphuric acid or sodium bisulphate or both, the paste being stirred and dried for 2 to 3 hours at 100 to 120‹ C. to reduce the water content to 50-60 per cent, further hydrolysis being carried on in a digester in the presence of nascent hydrofluoric acid produced by subsequently adding calcium fluoride to the partially hydrolized mass. An alkali, alkaline earth, cryolite, or hydrated fluoride of aluminium can be added at the second stage. In the digester the mass is kept at 120‹-130‹ C. for two to three hours at a pressure of 2-3 atmospheres. Further fluoride and dilute sulphuric acid may be added to increase the yield of nascent hydrofluoric acid. The mass is subsequently neutralized by milk or lime or sugar skimmings.

Title: Improvements in or relating to resinous laminates and production thereof

Filed: 1947-02-18
Abstract: 645,257. Laminated fibrous material such as paper. ST. REGIS PAPER CO. Feb. 18, 1947, No. 4644. Convention date, Feb. 28, 1941. [Classes 96 and 140] A heat-resistant resinous laminate comprises superposed layers of fibrous material such as paper impregnated with and consolidated by a thermoset synthetic resin such as phenol- or urea-aldehyde, one surface layer of the fibrous material being high in resin content, hard, and imporous, and the remainder of the fibrous material including the opposite surface being low in resin content and sufficiently porous to permit the escape of trapped gases. On heating the laminate, e.g. to bake an enamel coating applied to the imporous surface, gases evolved escape through the porous surface avoiding delamination or blistering of the hard, imporous surface. A sheet of fibrous material, e.g. absorbent Kraft paper, impregnated with a thermosetting resin in an amount exceeding the weight of the fibrous material is applied as a surface sheet to a stack of superposed layers of fibrous material impregnated with a relatively low content of thermosetting resin varnish, the assembly is subjected to heat and pressure, the pressure is momentarily released to permit escape of gases, and then resumed until the resin is fully set. In drying the impregnated sheets, the heat may be sufficient to bring the resin to incipient transition into the thermoset condition. The Specification as open to inspection under Sect. 91 comprises also the use of alpha cellulose, rag or sulphite paper, and of cresol- or xylenolaldehyde resins, the application of pigmented enamel coatings comprising a melamine-aldehyde resin, alone or modified with alkyd resin, or comprising an oil-modified alkyd resin. This subject-matter does not appear in the Specification as accepted.

Title: Hydraulically operated control rod drive system for pressurised water and boiling water reactors
Inventor: MEUSEL WILHELM
IPC: G21C7/16
Filed: 1968-01-30
Abstract: 1,209,953. Controlling reactors. MASCHINENFABKIK AUGSBURG - NURNBERG A.G. 30 Jan., 1968, No. 4762/68. Heading G6C. An hydraulic control rod drive system for a pressurized water or boiling water reactor normally derives its pressurized water from an auxiliary source but, alternatively, may utilize the pressurized water in the reactor. The system ensures that should a breakdown occur in the auxiliary source the reactor may still be controlled both for normal operation and scram operation of the control rod. As shown, a housing 2 attached to the reactor pressure vessel 1 encloses a cylinder having a smaller diameter section 6 and a larger diameter section 7, the cylinder receiving pistons 10, 12 interconnected by a rod 11 and controlling the movement of a reactor control rod 9. A valve 15 comprising a cylindrical shell 16 is biased by a spring 23 so that when there is no pressure acting on the lower end of the valve due to absence of pressurized liquid in pipe 4 or pipe 14 the valve has the position shown, Fig. 1, in which it is free from the seat 8 at the end of cylinder 7. Thus the valve 15 takes this position in the event of a breakdown in the auxiliary source of pressurized water connected to the pipes 4, 14 and in this position pressurized water from the reactor in the annular space 5 acts on the underside of the piston 12. To permit movement of the piston 12 to drive the control rod 9 into the reactor the water between the pistons 10, 12 is discharged by opening a valve 34<SP>1</SP> in pipe 34 or valve 35<SP>1</SP> in pipe 35, the smaller pipe 34 serving for normal rod insertion and the larger pipe 35 for scram operation. The rod 9 is returned by admitting pressurized water to the pipe 34 and opening a valve in a discharge pipe 33. For normal operation, pressurized water from the auxiliary source is supplied through pipe 14 for normal control rod insertion and through pipe 4 for scram operation. In these conditions, valve 15 is lifted against the seat 8 and a valve 19 biased by a spring 21 within the valve 15 is lifted from its seat 26, Fig. 2, to permit the pressurized water to act on the piston 12.
