Abstract: FLUID FILM CONTINUOUS PROCESSING APPARATUS               ABSTRACT OF THE DISCLOSURE           Material such as panels, boards, and flexible sheets are produced and processed while passing between two or more surfaces at least one of which has a thin layer of pressurized fluid in direct contact with the product.  While in this proces zone, the item is shaped, coated, smoothed, textured, heated, cooled, compressed, dried, and/or impregnated.  For example, expandable resin is deposited in a continuously formed bag of upper and lower sheet material so that the resin may expand and cure as it is drawn in through a fixed rigid mold having upper and lower (and perhaps side) porous material walls through which pressurized fluid is passed to provide a fluid bearing support and molding surface.  The temperature, pressure and flow of the fluid is monitored and controlled separately at spaced locations along the length of the mold to control curing rate, foaming rate, surface characteristics and resistance of material moving through the mold.  The surfaces may be planar or curved and may be parallel or variably separated in lateral cross-section.  They may also be planar or curved and parallel or variably separated in longitudinal cross-section.  The fluid layer is formed by passing a fluid under pressure through a porous wall having the shape of the desired fluid film configuration.  This film of fluid moves across the surface of the item being processed, separating the item from the wall to eliminate sliding friction while subjecting the item to pressure, and/or heat, heat loss, absorption, evaporation and impingement.

Abstract: (PM 819) Abstract This disclosure relates to a process for the treatment of tobacco materials. More particularly, the disclosure relates to process that comprises contacting tobacco with an aqueous enzyme solution exhibiting cellulase activity, incubating the tobacco-enzyme mixture, and thereafter expanding the tobacco material. Tobacco materials treated in this manner exhibit an enhanced capa-bility for expansion, thereby resulting in a significant increase in filling capacity when compared to untreated expanded tobacco.

Abstract: Abstract A light-tight cassette.      A light-tight cassette for holding and dispensing a roll of light-sensitive material comprising an extrusion moulded shell (11) and injection moulded end caps (12,13).      Difficulties which may arise in fitting the end caps to the shell are avoided by providing the inner face of the end caps with axially projecting  corner portions (26,27,28) having a three-dimensional form providing outwardly facing surfaces which are outwardly convexly curved both in radial planes containing the axis of the hub portion (44) of the cap and in planes normal to said axis.  The said corner portions fit inside corner regions of the shell and have a self-centralizing effect if -the caps and shell are pushed together in abaxial and/or relatively angularly skewed relationship.

Abstract: ABSTRACT OF THE DISCLOSURE           A draft sensing apparatus for an agricultural tractor or the like.  The tractor is provided with a transversely extending bending shaft (18).  The forward ends of a pair of lower draft links are secured to the outer ends of the shaft (18).  The shaft (18) will bend in proportion to the draft in the links.  The draft is sensed through a Hall effect device (52) carried by a yoke (54).  The forward end of the yoke (54) is pivotally mounted on a fixed transversely extending shaft (48) and the rear portion of the yoke slideably receives the bending shaft (18).  A link (60) pivoted to the yoke (54) has one end portion contacted by the shaft (18) and the other end is in contact with one end of a spring biased pin (70). The other end of the pin carries a permanent magnet (78) in axially alignment with the sensor (52).  As the shaft deflects as the draft varies the magnet (78) will be shifted towards and away from the sensor (52) causing a voltage variation in line (98).  By mounting the sensor (52) in the manner indicated the effect of vertical deflection of the bending shaft (18) will be reduced to insignificant levels as compared to horizontal deflection.

Abstract: RCA 74,057 Abstract of the Disclosure A selectivity network is provided for a synchronous detector, a reference signal circuit, and an AFT circuit. The selectivity network comprises a first tuned circuit coupled across two terminals of the reference signal circuit and tuned to the desired frequency of the I.F. picture carrier. A second tuned circuit is lightly coupled to the first tuned circuit and is coupled across two inputs of the AFT circuit to provide a frequency dependent phase-shifted reference signal to the AFT circuit. The first tuned circuit includes a trap circuit tuned to provide attenuation about a frequency intermediate the frequency of a sound carrier and that picture signal sideband frequency which, upon detection, results in a video signal corresponding to the intercarrier sound second subharmonic frequency. The trap in the reference signal tuned circuit minimizes quadrature distortion in the reference channel and the resultant harmonic distortion in the video signals, which causes sound buzz. The frequency notched reference signal is applied to the AFT tuned circuit, which causes a balancing of the pull-in range of the AFT circuit about the desired picture carrier frequency, thereby immunizing the AFT circuit against noise-pulling. The frequency notch in the AFT circuit at the indicated frequency also minimizes AFT effects of a frequency offset co-channel sound carrier, allowing the automatic acquisition of signals which are offset in frequency toward the lower adjacent channel.

Abstract: Abstract of the Disclosure The present invention relates to a method for the activation, and reactivation of PMA based catalysts by treating the catalyst precursor with a nitrogen-containing compound such as an oxide of nitrogen gas or a nitrogen acid such as nitric or nitrous at a temperature of from about 100°C to about 400°C.  The method can be employed for activation in a reactor by loading the catalyst pre-cursor, adjusting the reactor temperature to one suitable for activation and optionally sweeping the reactor with an inert gas followed by the treating step.  The method can be employed for catalyst reactivation in the reactor by term-inating the feed of reactant to the reactor, adjusting the reactor temperature as may be necessary to one suitable for reactivation and sweeping the reactor with a gas. Alternatively, the catalyst can be removed from the reactor for reactivation.
