Abstract: 1,111,654. Valves. LAYCOCK ENGINEERING Ltd. 4 Nov., 1964 [4 Nov., 1963], No. 43384/63. Heading F2V. A pressure relief valve designed for application to an epicyclic overdrive unit for an automobile transmission system comprises a first annular piston element 6 with a skirt 7 and a second piston element 9 with a head 10 both slidable in a bore 2 between a return outlet 3 and pump delivery and pressure output ports 4 and 5. A spring 13 forces the first piston element 6 on to the second element against the fluid pressure. This pressure forces the head 10 upwards as it increases, carrying the first element with it, until stem 11 abuts the end of the cylinder. A further increase in pressure acts on the first element to force this away from the second element and so open a passage to the outlet 3. A plug 17 limits downward movement of the piston elements and a rubber washer provides a sealing surface between the elements.

Title: Improvements in or relating to the Malting of Barley or other Cereals.
Inventor: DIXON BERNARD
Filed: 1966-01-11
Abstract: 1,173,611. Malting. DIXON MALT CO. Ltd. Jan. 4, 1967 [Jan. 11, 1966; Sept. 30, 1966], Nos. 1302/66 and 43894/66. Addition to 1,025,263. Heading C6E. In a method of malting barley or other cereal comprising steeping the grain, draining away the steep water and permitting the grain to form rootlets in a first aerobic atmosphere, subjecting the grain to an anaerobic atmosphere and then restoring the grain to an aerobic atmosphere for modification of the grain, the condition of the rootlets is ascertained and the aerobic atmosphere is restored when they become flaccid and translucent. The anaerobic atmosphere may be induced: (1) by reducing the amount of oxygen in contact with the grain while preventing the access of further oxygen, thereby allowing the residue of oxygen to be converted into carbon dioxide by the respiring grain; (2) by displacing the first aerobic atmosphere by an inert non-toxic gas e.g. carbon dioxide or nitrogen (the first aerobic atmosphere may be displaced by water and the water displaced by the anaerobic atmosphere); (3) by extracting the first aerobic atmosphere from the vessel holding the steeped grain e.g. to an absolute pressure of 250 mm. Hg or less; (4) by adding more germinating grain and then sealing the vessel; (5) by actively removing the oxygen physically or chemically e. g. by a reducing agent (sodium dithionite) or an oxygen absorbent (alkaline pyrogallol); or (6) by steeping the grain and maintaining it in the first aerobic atmosphere in a flexible and potentially airtight container, then collapsing the container to reduce its volume until it is substantially filled by the grain and sealing the container. The malting, drying and kilning of the grain may be carried out in the one containing vessel.
