IPC: G06M3/02
Filed: 1968-08-08
Abstract: 1282871 Counters KENT METERS Ltd 5 Aug 1969 [8 Aug 1968] 38017/68 Heading G4D Each time one wheel of a counter completes a revolution it causes a quick rotation of another element to send an impulse to a distant electric register. The invention is applied particularly to water meters. A pin 22, Fig. 1, on the units wheel drives a pin 21 on an eccentric segment 20 until it reaches top dead centre when the segment falls smartly so that a permanent magnet operates a magnetic reed switch 23. This position coincides with transfer to the tens denomination. In a modification, Fig. 3, rotation of the units wheel stresses a spring 26 until transfer when the transfer pinion 33 releases an abutment and therefore the magnetcarrying wheel. Signals to the distance register may be by cam-operated leaf, mercury or microswitch. Any denomination wheel may be coupled to the signal-sending element (Fig. 7, not shown).

Abstract: 1,134,103. Decorticating and skinning nuts. NATIONAL RESEARCH DEVELOPMENT CORP. 17 Dec., 1965 [22 Sept., 1964], No. 38651/64. Heading A2Q. In a process and apparatus for decorticating hard-shelled nuts or cocoa beans, the nuts or beans are soaked in water, airdried, subjected to centrifugal cleaning and cracking, in which some of the nuts or beans are cracked by being flung against hard surfaces, and broken and unbroken nuts or beans are then separated, unbroken ones are again subjected to centrifugal cracking, and the liberated kernels are separated from broken shells, as by a fluidized-bed flotation technique described in Specification 1,085,810. In decorticating and skinning cashew nuts, they are roasted, e.g. in hot air or gas, e.g. combustion gas from an oil-burner, between air-drying and cleaning and cracking, so that after roasting, the moisture content of the kernels is between 7 and 15%, and that of the shells is between 5 and 10%, by weight. The kernels are finally subjected to an operation akin to sand-blasting, which removes skins (testae) from the kernels and may also dry them. Particles of ice or solid carbon dioxide, or salt crystals may be used in the blasting operation.

IPC: C07C209/48
Filed: 1957-12-17
Abstract: Hexamethylene diamine is produced from adiponitrile by first purifying the nitrile by passing it, in admixture with a small proportion of water, repeatedly and alternately through columns of cation and anion exchange resins, and then subjecting the purified nitrile, dissolved in liquid ammonia, to hydrogenation with hydrogen at a pressure of 100 to 500 atmospheres and a temperature of 20 DEG to 80 DEG  C. in the presence of granules of porous nickel-aluminium alloy containing 40 to 60% of nickel, which has been activated with an aqueous solution of an alkali hydroxide. Hexamethylene diamine is produced in high yield, e.g. 98%, with only small proportions of by-products such as aminocaproic acid, secondary amines, and cis-1,2-diaminocyclohexane; moreover the catalyst remains effective for many days of continuous operation.  After being fractionally distilled once in vacuo, the hexamethylene diamine can be used, without further purification, together with an equivalent quantity of adipic acid for polycondensation to form polyamides of high molecular weight.
