Patent GB-396701-A (GB)
Title: Improvements in or relating to the manufacture of alkali metal chlorates
IPC: C01B11/14
Filed: 1932-02-04
Abstract: Alkali metal chlorates or solid products containing the same are produced by reacting chlorine, either pure or in admixture with inert gases such as air, with alkali metal carbonate and optionally bicarbonate in the presence of 3-20 per cent of water, reckoned on the weight of the carbonate.  The water may be introduced as steam or as a spray, or as vapour carried by the chlorine or as water of crystallization of the alkali metal carbonate.  A reaction temperature of 60-80 DEG  C. is preferred.  In examples relating to the production of sodium chlorate, the carbonate is spread in layers and preferably periodically raked while being treated with chlorine. Alternatively, soda ash containing 3-12 per cent of water passes through a rotating iron tube lined with earthenware, in countercurrent to a stream of chlorine-containing gas, initially at 110 DEG  C.  The issuing gas may pass to the atmosphere through a scrubbing tower, or be recycled with added chlorine.  The solid product may be used as a weed-killer or may be leached, sodium chlorate being recovered by evaporation and crystallization.ALSO:A solid admixture of alkali chlorate and chloride with small quantities of unchanged alkali carbonate and bicarbonate for use as a weed-killer is obtained by reacting chlorine with alkali metal carbonate and optionally bicarbonate in the presence of 3-20 per cent of water reckoned on the weight of the carbonate.

Title: Improvements in control of nuclear reactors
Inventor: DALE WALTER BERNARD
IPC: G21C7/32
Filed: 1969-01-21
Abstract: 1284083 Reactor power plant UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Jan 1970 [21 Jan 1969] 3488/69 Heading G6C A method of controlling an advanced gas cooled reactor so as to vary the outlet gas temperature in accordance with the load demands, comprises varying the levels of the neutron flux and of the coolant flow at the different regions of the core, these variations being made in such manner that in selected core regions the variations are greater or less than the average of the variations obtained from considering all the core regions together. Thus, for a large load reduction, the greatest reduction in gas outlet temperature is made to occur at the central core region. The variations are obtained by automatic movement of flux shaping rods and flow control gags in the fuel element channels. For small load charges only certain of the rods and gags may be moved and the fuel elements in those channels may be strengthened to better resist the thermal cycling.

Title: Extinguishing chambers for electrical circuit breakers
IPC: H01H33/46
Filed: 1940-02-27
Abstract: 537,093. Liquid-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 27, 1940, No. 3604. Convention date, March 3, 1939. [Class 38 (v)] An arc-extinguishing chamber has apertures 9, 10 provided in the two parts 13, 14 of a double wall of the chamber, so that the arc - pressure drives liquid from the space between the wall parts out of the apertures 9 and, by obstructing the escape of gas, enables adequate pressure to be maintained. With excessive pressure, escape of gas is possible, as also after the arc is extinguished, the latter feature being useful where the circuit is required to be remade at once. Slidable in the inner cylinder 11 is a spring-controlled collar 17 provided with inner and outer cylinders 16, 15, the whole constituting a differential piston which is driven downwards to expel liquid from the space between cylinders 11, 15, through apertures 25, and into the space between the cylinders 15, 16 to quench the arc. Liquid is also expelled from the space between cylinders 11, 15, the arrangement preseating the advantage over a simple extinguishing chamber (Fig. 1, not shown), that the flow is at a much higher pressure than that in the arcing space, and therefore more obstructive.

Title: Razor blade dispenser
IPC: B65D83/10
Filed: 1962-02-01
Abstract: 938,641. Razor blade dispensers. PHILIP MORRIS Inc. Feb. 1. 1962 [April 4, 19611, No. 3818/62. Class 18. FIG.4. A razor blade dispenser comprises an upper member 10 which may be of plastics and a.lower member 16 which may be of metal and which snap-fits on to the upper member. The uppermost blade is dispensed through a slot 32 from an upwardly spring-stressed stack 37 by forward movement of a slide 34 which engages, by means of projections 42 thereon, the rear edge of the blade. To prevent the dispensing of more than one blade at a time a vertically-yieldable post 45 is provided which passes through aligned slots 38 in the blades and which is maintained in a depressed position by a projection 46 when the slide 34 is in its rearmost position. The projections 42 project by less than the thickness of a single blade below the slide 34 and the projection 46 by more than the thickness of one blade, but less than the thickness of two blades. With forward motion of the slide the uppermost blade is slid over the post 45, but any forward movement of the blade next below is blocked by the post, the effectiveness of the block increasing since the post rises after passage thereover of the projection 46. The post 45 is made by suitably bending and attaching together plates 55, 56 (see Fig. 9) bent from a resilient sheet-metal plate 50, which plate forms a false bottom for the dispenser. In the uppermost position of the post i.e. with its horizontal top surface above the level of the lower surface of the slide, the sheet 50 is unflexed. U.S.A. Specification 2,792,933 is referred to.
