Abstract: 827,626. Couplings for gas cocks. CANNON INDUSTRIES Ltd. March 27, 1958 [Dec. 29, 1956], No. 39579/56. Class 99(1). In a hollow gas rail 7 used to supply a number of individually controlled burners, a gas control tap 10 comprising a hollow cock body 13, which accommodates a taper plug 21, is passed into the gas rail through a relatively large opening 11 in one wall thereof and bridges the interior space 16 of the rail so as to be surrounded by gas, and the outlet end of the body is passed through a smaller opening 12 in the opposite wall of the rail where an annular face of a sealing shoulder 14 on the exterior of the body is urged to make a compression seal against an inner face of that wall ; the body projects beyond the opening 12 and has an outlet 9 for connection to a gas burner nozzle or a tube to such a nozzle. As shown, the shoulder 14 is urged against a sealing ring 18 of aluminium or copper and by a nut 19 screwed into the opening 11 and bearing on an annular shoulder 15 of the body 13. The latter has diametrically opposed gas inlet ports 22 which can be aligned with ports 23 in the plug 21 by rotary movement of the plug.

A radar reflector for example for suspension from a balloon comprises an inflatable framework including a king-post which has a number of radially-projecting arms. Reflecting surfaces are resiliently connected to the framework, for example by elastic bands, so that expansion of the framework does not stress the surfaces unduly. The surfaces are readily detachable and may be formed of knitted wire, metallized textile material, or metallized perforated plastic or paper. The reflector may be erected automatically from a gas cylinder when the reflector has reached a certain height; a safety valve prevents the internal pressure from becoming too high. The reflector may be mounted in a balloon. Specification 812,376 is referred to.

Filed: 1971-09-09
Abstract: 1368275 Data processing SCHLUMBERGER INLAND SERVICES Inc 9 Sept 1971 [9 Sept 1970] 42065/71 Heading G4A Well log data obtained from separate logging operations through a borehole are machine processed by determining the depth displacement, e.g. due to cable stretch, between a sample of a first log data and the corresponding sample of a second log data, repeating the depth displacement determination or successive samples of the first data and corresponding samples of the second data, and comparising the depth displacement values from a number of samples to select a valid displacement value for at least one of the samples. A displacement value may be selected as valid when a given number of equal values occur successively, the valid value then being ascribed to all samples from the first to the last found to have that displacement value inclusive. An indication of the quality of the valid displacement determination may be given as a function of the total number of samples to which a particular diplacement is ascribed and the number of samples for which that value of displacement was actually determined. The depth displacement for each sample may be obtained by combining samples of the first data over a first range, including the particular sample, with samples of the second data over a second range, including the corresponding sample, to compute a correlation function for each of a plurality of positions of the second range relative to the first range, determining the correlation function which has the highest value, and selecting the depth displacement corresponding to this function provided the value of the function exceeds a given limit. Having determined the valid depth displacements for the second data, the second data may be transferred by these amounts so that the first and second data correspond relative to depth.
