Abstract: Abstract of the Disclosure A fluid pressure energy translating device of the sliding vane type comprising a cam ring including an internal contour, a rotor having a plurality of vanes rotatable therewith and slidable relative thereto in slots in the rotor with one end of each vane engaging the internal contour.  The rotor and internal con-tour cooperate to define one or more pumping chambers between the periphery of the rotor and the cam contour through which the vanes pass carrying fluid from an inlet port to an outlet port.  At least one cheek plate is associated with the body and rotor.  Two pressure chambers are formed for each vane and each vane has two surfaces, one in each chamber, both being effective under pressure in the respective chambers to urge the vanes into engagement with the cam.  A generally annular internal feed passage is formed entirely within the rotor and communicates with one set of the pressure chambers.  A radial passage is provided on each vane extending from the the tip of the base thereof, so that cyclically changing pressure is supplied to the other set of chambers.  Arcuate grooves are provided in the face of the cheek plate in the dwell zones, and a hydrostatic pressure pad is associated with the opposite face of the cheek plate and circumscribes the arcuate grooves.  An opening extends from the arcuate grooves through the cheek plate to the hydrostatic area.

Abstract: METER REMOVAL INDICATOR         Abstract Electricity  meter   fraud   is  detected  by  incorporating  a unidirectional cyclometer-type register into a meter.   The register is actuated each time the meter and cover assembly (which is factory sealed)  is removed from its associated socket by an actuating arm assembly which is in contact with the socket.  In one embodiment the actuating arm includes  a  rod which  protrudes  through  an  opening formed in the base of the meter and is biased into contact with the socket so that when the meter is removed from the socket the register is actuated.   Alternatively,  the actuating arm is connected to a sliding-type meter terminal which is actuated upon insertion and/or removal of the meter base with respect to the socket.  In a further arrangement, a switch is provided in the base of the meter and is arranged to energize a solenoid to actuate the register whenever the meter is removed from its socket.  The register can include one or more  drums,  with  the  drums  each  having  a  plurality  of  markings provided thereon, such as the digits 0-9, indicative of the position of the drum.   Upon the removal of the meter from its socket the register is actuated causing different markings to be displayed.  The register drum is designed to rotate in only one direction and jams upon reaching a predetermined position so that the markings originally displayed by the register cannot be brought back into view by a person who has fraudulently removed the meter from its socket.

Abstract: Abstract A Method of Measuring the Nuclear Magnetic Resonance for Use in NMR Tomography In an NMR tomography method, the nuclear spins are caused by a pulse sequence to supply in one pass a number of successive induction signals, whereupon the induction signals corresponding to each other as regards their succession in time are processed by calculation to form a plurality of image signal sets corresponding to a sequence of section images which differ from each other by the intensity of the induction signals varying according to the relaxation time T1 or T2. Thereafter one establishes for each image point associated with a single volume element of the body cross-section a function describing the variation in time of the image signals associated with the respective image points in the different image signal sets, and generates a further image signal set by extrapolating the functions thus established to a point of time situated before the pre-determined measuring moment defined by the start of a pulse sequence following a first output pulse, and uses the image signal set thus obtained for producing a section image.

Abstract: ABSTRACT      In the manufacture of packing containers of the type containing a liquid product with a certain portion of "solid" particles (e.g. soup with pieces of fruit) it is difficult to fill the packing con-tainers in such a manner that the desired proportions of liquid and solid contents are safeguarded. This is the case in particular in modern, fast working packing machines, since the filling time is short and a rapid filling, moreover, increases the risk of contents ending up in undesirable places and rendering difficult the sealing of the packing container. In accordance with the invention which relates to a method as well as to an arrangement for the manufac-ture of packing containers, this is solved by feeding the solid and liquid parts separately via two filling pipes, the feeding of the liquid contents being ended only after the feeding of solid particles has been ended.

Abstract: ABSTRACT OF THE DISCLOSURE         A partial painting method suitable for partially painting a workpiece or article of a complex surface shape.          A surface of the workpiece is coated with   strippable paint. The coated strippable paint is dried into a strippable film on the workpiece surface.  A laser beam is applied to the strippable film along a prescribed cutting line so as to cut the strippable film.  A portion of the strippable film corresponding to a first area of the workpiece surface to be painted is peeled off, while the remaining portion of the strippable film is left adhering on a second area of the workpiece surface to be unpainted, thereby masking of the workpiece is completed.  The first area is then painted with a paint to form a final paint coating.  The strippable paint contains powder, such as of graphite, having a substantially high ligh energy absorptivity, so that the strippable film can reliably be cut by the laser beam without damaging the surface of the workpiece which may be molded of synthetic resin that is relatively soft and is easily softened with heat applied.

Abstract: RECOVERY OF SULFOLANE     ABSTRACT                                     I In a process for the production of t-butylstyrene by oxydehydrogenation of t-butylethylbenzane, sulfolane solvent employed in the preparation of purified t-butylstyrene product is recovered for recycle by extraction of aqueous sulfolane with a liquid aliphatic or aromatic hydrocarbon having a boiling point less than the boiling point of sulfolane.  The raffinate is then distilled to recover sulfolane containing only small quantities of water and substantially free of organic contaminants.     BACKGROUND OF THE INVENTION    The invention relates broadly to a solvent recovery process and in particular to the recovery of sulfolane used in the purification of t-butylstyrene.    Tertiary-butylstyrene (tBS) is a compound which is advantageously prepared by catalytic oxydehydrogenation of t-butylethylbenzene (tBEB). It has many uses, e.g. as a chemical intermediate, as a monomer or comonomer in the production of polymeric materials and the like.  Tertiary-butylstyrene has often replaced styrene in some applications because desirable physical and chemical product properties result from such a substitution.  In addition, there are processes where styrene is not suitable but where tertiary-butylstyrene functions well. Because tBS belongs to the same family as styrene, there are similarities in the chemistry.  One of the common properties is the tendency for the styrenics to polymerize whenever they are activated by chemicals or by heat. Some of the techniques used in purifying styrene can be used to purify tBS. However, because the boiling point of tBS is about 70°C higher than that of styrene, the tendency for tBS to polymerize is much greater than that of styrene in any of the commercial processes for purifying styrene. Some of the differences between styrene and tBS are derived from the compounds of the dialkenylbenzene family, that are present in tBS but not in styrene.  These crosslinking compounds can polymerize to give a type of
