Abstract: Abstract:          An NMR imaging apparatus detects a nuclear spin resonance signal from an object placed in a magnetic field to produce images of the object.  At an instant when the spins come into phase after signal detection by a first spin excitation, RF magnetic field pulses are applied for rotating the direction of the spin to that opposite its initial state.          The spin excitation and the signal direction change are then applied a second time to measure different data in relation to the effect of the relaxation time from the first measure-ments.  By repeating these sequences, it is possible to pro-duce a plurality of images, such as an intensity image and a relaxation time enhanced image.

Abstract: Abstract:     A satellite dish is required to be pivotally mounted so that it can be trained to receive from different synchronous satellites along the Clarke Belt.  The dish is rendered better balanced by arranging for its pivotal axis to pass through its centre of gravity.  This axis is slightly inclined to the plane of the rim of the reflector, which plane determines the direction in which the dish is looking.  The arrangement enhances the stability of the dish and enables a lighter and less expensive motor drive to be used.

Abstract: Abstract An apparatus for wrapping relatively large articles, especially a plurality of individual packs (cigarette cartons), is simplified and improved in terms of its mode of operation, in such a way that packs pass through a first wrapping and folding unit for wrapping in one blank and then pass through a second wrapping and folding unit for alternately or cumulatively wrapping in a second blank.  The pack follows the same path irrespective of which blank is intended for wrapping alternately or cumulatively.  The packs always are discharged from the apparatus at the same point on a discharge conveyor track, and can be supplied to a common pack tower.  For this purpose, there are two folding turrets for wrapping the pack group with different blanks.

Abstract: ABSTRACT OF THE DISCLOSURE:          Anhydrous of substantially anhydrous formic acid is obtained by hydrolysis of methyl formate by a process in which, methyl formate is hydrolyzed in the presence of a carboxamide of the general formula (I):                                          (I) where R1 is alkyl or hydrogen, R2 is alkyl, R3 is hydrogen or a C1 to C4 alkyl, and R1 and R2 may form part of a 5-membered or 6-membered ring, and the sum of the carbon atoms in the radicals R1, R2 and R3 is from 1 to 14.  The mixture formed during the hydrolysis is separated into its individual components in a first distillation column which is divided into a feed part and a take-off part by separating means which are effective in the longitudinal direction.  During the process the hydrolysis mixture is fed into the feed part, while methanol and unreacted methyl formate are taken off as a top product and as a side product.  Formic acid and the carboxamide of formula I (as extracting agent) are taken off as an anhydrous or substantially anhydrous bottom product.  Water, preferably in liquid form, is removed from the take-off part. Finally the bottom product from the first distillation column is separated, in a second distillation column, into formic acid and the extracting agent.  This process avoids decomposition of the products and does not require liquid-liquid extraction to remove water.

Abstract: ABSTRACT OF THE DISCLOSURE      Two matrices, each bearing modulation to form a microgroove disc record, are fixed to half-moulds by means of sleeves, having first and second fixing flanges which extend into the gap between the matrices.   One of the flanges is an annular blade whose inner radial surface defines the edge of a moulded disc and whose thickness is slightly less than that of the moulded disc.   Formed integrally with, or attached to, the blade is a group of radially outwardly extending lugs which are attached to the body of its associated sleeve.   The other flange comprises a second group of lugs mounted to the body of its associated sleeve radially outward of the blade such that the second group of lugs may lie in the spaces between the first mentioned group of lugs.   The thickness of the lugs of the second group determines the thickness of the disc and the thickness of the lugs of the first and second groups differs, to determine a gap for escape of air along the first flange.   Spaces between the groups of the two interlaced lugs permit a controlled excape of air from the periphery of the record without the formation of peripheral flash.

Abstract: MECHANICAL  WRIST MECHANISM                    ABSTRACT     A three-axis wrist mechanism has three independent rotational axes with two points of mutual intersection which are offset from each other.   The  offset  provides  a  generous  bend radius for the wrist.  First and second housing structures  contain  the  first  and  second  axes while the third axis is disposed within a tool support member.  The first housing structure is adapted to be mounted to an outer tubular member of the arm of a robot to rotate independently of the rest of the mechanism.  Gear trains of the mechanism provide the independent rotation of the second housing  structure  and the  tool  support member to permit selective positioning of a tool-mounting  surface  of  the  tool  support  member within a work  envelope.   The gear  trains  are arranged  so  that  an  unobstructed  passage  is maintained between an arm-mounting surface of the first housing  structure  and  the  tool-mounting surface of the tool  support member for accom-modating hoses and/or wires which are used to transmit fluid and power to a tool mounted on the surface of the tool support member.

Abstract: PROCESS FOR PREPARING CERAMIC MATERIALS       WITH REDUCED CARBON LEVELS                          ABSTRACT           A process for preparing ceramic materials with reduced carbon levels is described.  The process involves treating a silicon-containing preceramic polymer with ammonia at a temperature of 550-800°C. for a time sufficient to reduce the carbon content prior to pyrolysis at 900-1500°C. Another process also involves the pyrolysis of a silicon-containing preceramic polymer in an ammonia atmosphere.  The carbon level of ceramic materials produced by this invention can be controlled to a given, desired level by varying the process conditions.  Suitable silicon-containing preceramic polymers include polycarbosilanes, polysilazanes, polysilanes, organosilsesquioxane-containing sol-gels, and organopolysiloxanes which are capable of being converted to ceramic materials when fired to elevated temperatures. Ceramic fibers can be prepared by the processes disclosed which contain less than 0.25 weight percent carbon.

Abstract: Abstract of the Disclosure A detector for charged particles, i.e. secondary electrons or ions emitted from a bombardment area of a specimen in an instrument such as a scanning electron microscope or analytical instrument, consists of a collector, e.g. a scintillation surface highly charged with a voltage of the opposite polarity from that of the particles, for receiving the particles and providing an output proportional to the number thereof.  A grid, charged with a voltage of the same sign as the scintillation surface, but to a lower value, is located between the scintillation surface and the bombardment area, and a probe in the form of a wire electrically connected to the grid projects into the vicinity of the bombardment area which is in a confined space between the specimen and the instrument.  The result is to set up an electrostatic field around the wire, causing a significant number of the charged particles to orbit the wire and travel to the scintillation surface.  The detector has better performance in situations requiring a relatively long "reach" into a confined space than has been attainable with previously known detectors.  As a result, the detector is especially useful when the specimen under examination is relatively large, e.g. a large silicon wafer.
