Granted: 1983-04-19
Abstract: ABSTRACT OF THE DISCLOSURE:              The invention relates to a process for the prepa-ration of alkyl esters of oxalic acid, wherein said esters are obtained by reaction, in a gaseous phase, of an alkyl nitrite having the formula R-ONO, wherein R represents an alkyl having from 1 to 10 carbon atoms, with carbon monoxide in the presence of at least one catalyst selected from the group consisting of: a) rhodium, iridium, platinum , gold and the salts thereof, with or without a co-catalyst selected from the group consisting of iron, copper and the salts thereof, and b) palladium in combination with a co-catalyst selected from the group con-sisting of iron, copper and the salts thereof, the salts of the hereinabove defined metals being selected from the group consisting of chlorides, sulphates, nitrates, acetates and acetylacetonates, at a temperature between 50 and 500°C, under at least atmospheric pressure.  This process allows a simple an unexpensive preparation of oxalic acids ester in high yields and high quality.

Abstract: ABSTRACT      A fracture that conducts fluid within confines of an underground rock formation without the need for part1-culate proppant materials to hold opposing fracture faces apart is created by a method in a long portion of a hole drilled into the formation has its axis slanted with re-spect to the directions of the principal stresses, and is pressurized rapidly over its entire length with fluid, pre-ferably by detonating an explosive therein.      A hypothetical fracture plane is defined as that plane containing the axis of the hole which is under the least compressive normal stress.  When the orientation of the hole axis is such that there is a substantial shear stress on the hypothetical fracture plane, but the normal stress thereon does not greatly exceed the minimum principal stress, the fracture created lies close to the hypothetical fracture plane, and is conductive to fluids.  The fracture is conductive be-cause it is held open by the misfit between the opposing faces which arises from the shear displacement of the faces that occurs when the existing shear stress is release by the forma-tion of the fracture.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for measuring the percentage of moisture content and weighing of a sheet-like object has a couple of metal box sections for providing a cavity with openings, which co-operatively form a cavity resonator, arranged facing at the openings to each other with a gap, interposed therebetween.  In measurement, the sheet-like object is inserted in the gap.  The percentage of moisture content of the sheet-like object is measured by detecting the variable resonant voltage of a microwave signal in-troduced into the cavity resonator.  Weighing of the sheet-like object is measured detecting the variable resonant frequency of the microwave signal introduced.

Abstract: ABSTRACT OF THE DISCLOSURE           A control member for supplying a pressure responsive device with pressurized fluid in response to an input signal.  The control member has a housing with a chamber therein.  The chamber is connected to a source of pressurized fluid through an entrance port, to a pressure responsive device through first and second operational ports and to the surrounding environment through an exit port.  A lever located in the chamber has a bore therein that is connected to the entrance port to define a flow path for the pressurized fluid through the chamber. Depending on a desired operation of the pressure responsive device, an Input signal is applied to the lever to bring the bore into communication with one of the first and second operational ports to allow pressurized fluid to flow to the pressure responsive device while the other operational port is connected to the surrounding environment through the chamber. When the input signal terminates, a pair of springs move the lever to a null position intermediate the first and second operational port to terminate the pressurized fluid communication to the pressure responsive device.
