Abstract: ABSTRACT    An electromagnet for producing the constant magnetic field required for use in NMR tomography consists of a cylindrical field coil and a stable cylindrical shell made of iron encompassing and simultaneously supporting the coil.  The field coil may comprise constituent coils, including error coils, and is capable of producing an at least approximately homogeneous magnetic field within the space defined by the field coil for receiving the object to be examined.  Due to the strictly symmetric geometry of the coil assembly, the homogeneity of the magnetic field is not adversely affected by temperature fluctuations, even if the dimensions of the apparatus are such that the coil will admit a human body.  The cylindrical shell, however, does not only serve as an extremely stable supporting means, but also forms the vehicle for a magnetic reflux by which the energy requirements of the magnet are considerably reduced, and further, also consitutes shielding means both against external magnetic fields and electromagnetic interference and radiation from the high frequency field produced in NMR tomography.  The cylindrical iron shell may be provided at its end portions with operational members such as annular discs and tubular studs and may be closed by iron covers, so that its effectiveness may even be further enhanced.

Abstract: ABSTRACT OF THE DISCLOSURE     A tool joint for earth boring drill pipe members  has features that increase the amount of torque required to yield the connection.  The tool joint has both external and  internal  make-up  shoulders.   The  pin  and  box are dimensioned  so that  the box  face contacts the external shoulder while there still is a clearance between the pin face the internal shoulder.  At normal make-up torque, the  external  shoulder will  be  tightened  to  its  normal amount.  The internal shoulder will tighten to its  yield only if additional torque is encountered while drilling.          The  internal  shoulder  adds  to  the  amount  of torque required to yield the tool joint connection.

Abstract: TEMPERATURE ACTUATED AIR FLOW CONTROL AND GAS SAMPLER               ABSTRACT OF THE DISCLOSURE           A temperature actuated air flow control compris-es a fluid inlet for the gas sample which is connected to an exhaust line through an intermediate venturi chamber into which a gas such as air is vented in order to aspirate the flow of the gas through the inlet to the exhaust.  The amount of flow of the aspirating gas controls the quantity of flow of the sample gas through the inlet to the exhaust.          A valve chamber in the aspirating gas passage comprises a bimetallic plate which is flexed between a position in which it closes a flow passage for the aspirating gas to one in which it opens the passage.  The bimetallic plate is flexed by temperature change.  The device advantageously functions to provide for the inflow of a sample or test quantity of a gas and flows through a chamber having a gas sensor to determine the characteristics of the gas and is directed through a venturi section and out through an exhaust.  An aspirating gas such as air is directed into the venturi section and its quantity is controlled by the bimetallic element.  In a correct operating temperature the bimetallic element will be flexed to open the passage and permit the continuous sampling of the gas but if the temperature falls for example to a temperature which is below the dew point of the sample gas the bimetallic element may be chosen so as to close off the aspirating air and stop the testing at that time.

The results of the two scans are stored and compared by the microprocessor     to determine the ap-parent magnitude of the stage shift in arbitrary units.          This apparent magnitude is then equated to the known precise shift distance to calibrate the arbitrary units. The microprocessor     can then calculate the desired measure-ment from the data of either of the two scans stored therein.

Abstract: ABSTRACT    METHOD AND APPARATUS FOR THE MASS SPECTROMETRIC                 ANALYSIS OF SOLUTIONS    An electrospray ion source for a mass spectrometer capable of generating ions from samples dissolved in a solution comprises a capillary tube (30) through which the said solution is pumped into a first chamber maintained substantially at atmospheric pressure and in which an inert gas, preferably heated, is flowing in a direction counter to the flow of the solution, and a small orifice (4) in the end wall (1) of the chamber opposite to and aligned with the capillary. A high potential difference is applied between the capillary tube (30) and the end wall (1) so that the solution is electrosprayed into the chamber and ions characteristic of the sample are formed. These ions are desolvated to a controllable extent by the inert gas, which is usually heated to improve the efficiency of the process and increase the maximum permissible flow rate of solution. The ions so formed pass through the small orifice (4) into a second chamber maintained at a reduced pressure, and into a mass spectrometer (29). Alternatively an additional pressure reduction stage can be included, so that the ions pass into a third chamber maintained at a still lower pressure in which the mass spectrometer (29) is situated through a hole (23) in skimmer (24). The ion source is particularly effective for the production of unfragmented and unsolvated ions from thermally unstable or involatile samples, and may be used as a liquid chromatograph - mass spectrometer interface.

Abstract: ABSTRACT     Apparatus and method for protectively covering coupled components, such as in a coaxial cable splice, with a sleeve wherein one of the covered components is damaged when subjected to excessive heat which is less than that required for heat recovery.  A sealed bond is formed between a first length of the sleeve and a heat damageable component by heating and thereby foaming a foamable adhesive therebetween, the heat being insufficient to melt or otherwise damage the heat damageable component.  A second length of the sleeve is heat shrunk into engagement with another of the coupled com-ponents which is not  damageable at heat recovery temperatures.
