Abstract: 1407979 Raising submersible craft PLESSEY CO Ltd 3 Oct 1972 [5 Oct 1971] 46218/71 Headings B7A and B7S Apparatus for increasing the buoyancy of a submersible water going craft comprises a tank 1 having a first chamber 5 filled with a working medium such as water or oil and separated by an elastically deformable sock 4 from a second chamber 6 connected to a source of gas 21 via a variable pressure reducing valve means, with pressure operated means which controls the valve means so that the gas pressure in the second chamber 6 is automatically maintained not less than a value required to effect the expulsion of the working medium from the chamber 5 into the atmosphere surrounding the craft. In operation spool valve 54 is actuated by a starter button 24 and compressed air from bottle 21 maintains the valve actuated, and also passes via bores 48, 49, Fig. 3, and the variable orifice pressure reducing valve, afforded by the chamfered portion 60 of valve head 55 and bore 61, to chamber 6. The variable pressure reducing valve is automatically adjusted by the pressure operated means comprising a piston 40, Fig. 3, having opposed faces which are respectively subjected to the pressure of the gas in second chamber 6 via pipe 26 and bores 81, 82, and to the pressure of the surrounding water via axis bore 76 and inclined bores 78. The pressure of the sea water in piston 40 is also supplemented by an adjustable spring 71. If the piston 40 moves too far to the right due to a sufficiently high pressure in chamber 6 or a low pressure in the sea water, the air from chamber 6 is discharged via bore 57 when the piston head 55 is withdrawn therefrom. The working medium of chamber 5 is expelled via a spring loaded ON-OFF control valve 11, Fig. 8 (not shown).

Title: Method of operating vibrators to produce seismic signals
IPC: G01V1/04
Filed: 1975-11-10
Abstract: 1516866 Seismic signal generation; autocorrelation DEUTSCHE TEXACO A G 10 Nov 1975 [12 Nov 1974] 46419/75 Heading G1G A method for operating vibrators for generating seismic signals within a specified frequency range found suitable for an exploration target by means of a sinusoidal control signal, said control signal being determined in an automatic computing system, comprises the following steps: determining a reference autocorrelation function with low side lobes and frequencies within the specified frequency range, determining the amplitude spectrum of the reference autocorrelation function, determining the amplitude spectrum of the seismic signal as the square root of the amplitude spectrum of the reference autocorrelation function, determining the amplitude spectrum of the control signal of the vibrators from the amplitude spectrum of the seismic signal by means of the relation between control signal and seismic signal, and determining the variation with time of the frequency of the sinusoidal control signal from the amplitude spectrum of the control signal. The "Amplitude Spectrum" is the modulus of the generally complex frequency spectrum. Only for symmetrical functions, such as the autocorrelation function, is the frequency spectrum real and is thus, possibly apart from the sign, equal to the amplitude spectrum. An autocorrelation function comprising desired low secondary lobes may be provided with the aid of linear filters as employed in filter technology for smoothing oscillating signals.

The terms 'hardstock' and 'hard fat' refer to fatty acid triglycerides of which at least 50% of whose fatty acid radicals are saturated. The 'liquid oil' is a glyceride mixture which is liquid at 5‹ C. The hardstock may further include a second hard fat of a slip melting point higher than that of the bottom fraction and which is different from the higher melting triglycerides removed form the hard fat to form the bottom fraction.

The hard stock is then blended with sunflower, safflower, wheat germ and corn oils. Margarines are prepared by melting these fat blends, emulsifying with an aqueous phase containing milk or soured milk and crystallizing and working.

Abstract: 1,268,289. Gas analysis; determining critical temperatures. TOKYO GAS CO. Ltd. Oct. 9, 1970 [Oct. 9, 1969], No.48227/70. Heading G1B and G1D. To determine the carbon potential of a heat treatment furnace gas atmosphere, the carbon deposition temperature of the gas is directly measured by passing a flow of the gas over a carbon deposit detecting element 3 and a temperature sensing element 2 associated therewith, and varying the gas flow temperature, the carbon potential at the furnace temperature being calculated from the carbon deposition temperature. As shown, a thermocouple 2 and a carbon deposit detecting element 3, comprising a pair of electrodes which are electrically interconnected when a carbon deposit occurs to give an ON signal and disconnected when the deposit is decreased to give an OFF signal, are mounted in a support tube 6 which is longitudinally slidable in a watercooled guide 5 to vary its position in a duct 7 through the furnace wall 13. Holes 4 in the tube 6 allow gas flowing through the duct 7 to pass over the elements 2, 3. Signals from the carbon deposit detecting element 3 to a control device 10 cause a motor 9 to move the tube 6 to maintain the element 3 at a point where the gas temperature is equal to the carbon deposition temperature, utilizing the presence of a temperature gradient through the furnace wall. The thermocouple 2 is connected to a recorder 11.
