Patent GB-315853-A (GB)
Title: Improved method of killing weeds and preparations therefor
IPC: A01N25/00
Filed: 1929-05-27
Abstract: 315,853. Chipman, R. N. July 20, 1928, [Convention date]. Weed-destroying compositions. - Weeds are destroyed by dusting them with a mixture containing an initially dried deliquescent agent adapted on contact with plant tissue to absorb water to form a herbicidal solution. The mixture may consist of sodium chlorate mixed with sufficient dried calcium chloride ultimately to convert the sodium salt wholly into calcium chlorate and, preferably, to provide an excess of calcium chloride. The calcium chloride is wholly or partly dehydrated so that it absorbs any moisture from the chlorate and maintains the mixture in a dry powdered form until and during application, but thereafter deliquesces to provide an active liquid on the plants. The sodium chlorate may be replaced by calcium or magnesium chlorate, which may be in a crude moist form, in which case a smaller quantity of calcium chloride is employed. The powder may be put up in cans provided at one end with dusting apertures adapted to be closed when not in use by a cap and gasket. Calcium chloride may be replaced by any other dry powder having a similar property of absorbing an appreciable amount of water before becoming moist. Specification 322,438 is referred to.

Filed: 1953-06-17
Abstract: 743,277. Measuring rate of change of pressure. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. June 17, 1953 [Aug. 1, 1952], No. 16754/53. Class 106 (2). A rate of climb indicator comprises a chamber 1 having a small opening 2 communicating with the exterior, pressure responsive means 3 for indicating the difference in pressure between the inside and the outside of the chamber 1 and means for causing a change in the volume in chamber 1. As shown, the means comprises a piston 7 but a variable liquid level or bellows could also be used. Before the apparatus is used to measure a rate of change of pressure, the volume of the chamber 1 is suddenly altered by the piston 7 to produce a pressure difference across the measuring means 3 similar to the pressure difference expected. This pressure difference produces a temperature change in the gas in the chamber in an opposite sense to that which will be produced when the chamber enters into operation. This arrangement is stated to reduce the transitory period necessary before the difference in pressure across the pressure responsive means 3 may be considered to be proportional to the rate of variation of the external pressure.

Continuous casting apparatus comprises a mould 31 which is in sealing engagement with an outlet conduit 14 connected to the chamber 10 of a degassing device or alternatively a ladle or tundish, a starter bar 33 sealingly engaged with a removable plate 35 sealing the bottom of the mould during the initiation of the casting process, means for introducing gas at super atmospheric pressure into the mould and means for sensing the level of metal in the mould and operable to automatically control the gas pressure to maintain a predetermined level. When using the degassing device the chamber 10 is evacuated and molten metal is drawn from a tundish into the chamber, a disc 24 having been first ruptured, and the metal entering the chamber is broken into droplets, degassed, and then coalesces on the chamber walls and subsequently flows to the mould through the conduit 14. When a predetermined level in the mould has been reached the starter bar is withdrawn, the seal of the plate 35 broken and the casting operation subsequently proceeds. The control of the metal flow to the mould is effected by the control of the inert gas supplied via pipe 42. If the degassing device is not used and the metal is supplied to the mould via the conduit 14 directly from a ladle or tundish the pressure of the gas supplied to the mould may be so adjusted as to effect both the level control and to allow gas to permeate through the molten metal and up the conduit to effect degassing.
