Abstract: ABSTRACT OF THE DISCLOSURE         An electromagnet for producing the constant magnetic field required in NMR tomography comprises a coil system of the Helmholtz double coil type.  The coil system is enclosed in, and supported by, a stable cylindrical shell. The influence exerted by the cylindrical shell on the homo-geneity of the magnetic field, which is generated by the coil system in an accessible interior space defined by it and suitable to receive the body to be examined, is compensated by the particular dimensioning of the field and error coils. The cylindrical shell is best made of a ferromagnetic material having low electric conductivity and is constructed of a plurality of axially serially disposed annular discs which are preferably divided into sectors.

Abstract: Abstract A current supply apparatus for an A.C. consumer contains an inverter (3) having transistors (T1-T6) and relaxation diodes (D1-D6), a mains energised rectifier (2), a translator chopper (4) between the rectifier and inverter, a smoothing circuit (5) behind the chopper, one base control circuit for each transistor (T1-T7), a measuring resistor (6) for the chopper current, a current measuring resistor (13) in the current return line of the inverter, a pulse generator (26), a pulse distributor (27) feeding the pulses of the pulse generator to the inverter-base control circuits (29) and a regulator (20) feeding control pulses to the chopper-base control circuit (24) depending on an operating parameter of the inverter.  A blocking signal is feedable to all the base control circuits depending on an overcurrent measuring signal derived from the associated current measuring resistor.  To separate the low voltage portion comprising the regulator, pulse generator and pulse distributor from the high voltage of the part containing the rectifier, chopper and inverter as far as high voltage coupling is concerned, and to safeguard the high voltage part from overcurrents, the control pulses for the transistors (T1-T7) are fed to the associated base control circuit (24, 29) by way of a respective optocoupler (22, 28) and a respective gate (23, 32) feedable with the appropriate blocking signal on over-current is disposed between the optocouplers (22, 28) and the base control circuits (24, 29) for the chopper (4) and the inverter transistors (T2, T4, T6) connected to the current return line of the invertor.

Abstract: SILOXANE STABILIZERS FOR INORGANIC SILICATES IN ANTIFREEZE/COOLANT FORMULATIONS                  (D#80,226-F) ABSTRACT OF THE DISCLOSURE         Stabilizers for inorganic silicate corrosion in-hibitor additives in antifreeze/coolant formulations are described.  The stabilizers have the structure   where n is an integer from 1 to 20 and R is a solubilizing agent.  The solubilizing group may be a cyano-terminated group, a diol ether group, an acid group, an amide group, a group which will yield a diol on hydrolysis, among others.          These stabilizers help prevent the inorganic silicate addi-tives from precipitating out and thus extend the shelf life of antifreeze formulations into which they are incorporated.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for reducing the water content of a lower-alkanesulfonic acid comprising placing a mixture containing water and the lower-alkanesulfonic acid onto the internal surface of an evaporator column so as to form a falling film of the mixture on the surface, operating the column at subatmospheric pressure and heating the surface so that water is vaporized from the mixture as the film flows down the surface.  Water vapor is removed at the top of the column, and lower-alkanesulfonic acid having a reduced water content is removed at the bottom of the column.  By this method, the formation of carcinogenic methyl methanesulfonate may be avoided without need for a two-step purification process.

Title: Method and apparatus for recording scrambled television signals

Granted: 1987-03-10
Abstract: ABSTRACT OF THE DISCLOSURE A scrambled television program is received and recorded in a scrambled fashion automatically in a video tape recorder by detecting program code signals placed in vertical blanking intervals of ten fields preceding the commencement of the scrambled program signal and upon sensing such program code signals the video tape recorder is activated to record the scrambled television program.  A stop code signal is arranged following the coded television program and is detected for stopping operation of the video recorder, so that the scrambled program is recorded without requiring the manual setting of automatic timers or the like.  In addition to the program code, a key code, and scene change signals are transmitted and these are used to produce a descramble pattern to descramble the television program when it is reproduced by the video tape recorder. By placing the key code after the television program, the entire program must be recorded in scrambled form before it can be reproduced and descrambled for viewing, thereby automatically recording the scrambled program without requiring a timer.

A bleed hole is provided from the back face of the bit to the chamber adjacent the diaphragm causing the diaphragm to be responsive to the pressure of the external downhole  fluid.   The  adjacency  of  the  reservoir  to  the sealed bearing cavity permits the pressure of the lubricant adjacent the seal to be immediately responsive to the pres-sure of  the downhole  fluid at  the diaphragm to prevent pressure differentials between the lubricant and the fluid at the seal.

Abstract: Abstract of the Disclosure A circularly polarized microwave oven.  Microwave energy is coupled from a waveguide above the ceiling to the cavity by a rotatable vertical probe extending through a circular aperture in the cavity.  A strip conductor closely spaced to the ceiling to limit radiation therefrom conducts the micro-wave current to an air dielectric patch antenna radially offset from the axis of the probe.  A vertical section of the strip conductor spaces the patch antenna more than one-eighth wavelength from the ceiling which functions as a ground plane.  The patch antenna is rectangular and the dimensions of its sides are selected to be respectively resonant above and below the operating frequency of the oven.  More specifically, the dimensions are selected so that the orthogonal currents parallel to the rectangle sides produce orthogonal radiated components that are equal in magnitude and separated by 90° in phase.  Accordingly, the resonant patch or flag antenna radiates substantially circular polarization.  The probe is supported on a vertical post of a support cradle suspended from the ceiling and the patch antenna is rotated about the axis of the probe.
