Abstract: ABSTRACT OF THE DISCLOSURE: Filaments or filament bundles, which are conveyed by a heated gas, are crimped by treating, them in a preheat chamber and crimping them in an elongate chamber from which the heated gas medium issues through longitudinal slits. A stream of cold gas is made to impinge on the outside or the lower one-third or the elongate chamber without allowing significant amounts of this cold gas to enter the said chamber. The resulting filaments or filament bundles have very good dyeing characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE                 Apparatus and method for automatic control of an image storage device.  The image storage device, of the type employing a liquid crystal, is utilized in an intermediate processing step during electrostatographic reproduction of the image.  An automatic sequence of voltages and illuminations are applied to the image storage device for erasing previously stored images and for preparing the device for storage of an image.  The stored image can be applied to a photoreceptor element of an electrostatographic machine for reproduction of the image.  The liquid crystal image storage device can be utilized in conjunction with apparatus for displaying signal encoded data.  The display of the signal encoded data can be in a format inconvenient for direct application to the photo-receptor, the image storage device serving as a buffer memory for the image.  The stored image can be utilized in conjunction with the electrostatographic machine to provide single or multiple copies of the image.

Abstract: MULTI-AXIS LOAD CELL            ABSTRACT      A multi-axis load cell of the type adapted to generate signals corresponding to each of the various force and moment components exerted on the load cell is disclosed, comprised of a hub and a housing inter-connected by three flexure arms, each flexure arm fixed at one end to one of the hub or housing and at the other end to a beam flexure element fixed to the other of the hub or housing.  Each flexure beam is designed to be readily deflected in directions aligned with its respective flexure arm but offers substantially greater resistance to deflection in other directions, so that a centering bias force is provided without restricting the bending deflection of the flexure arms relied on to measure the force and moment components.          Two sets of displacement transducers are provided, each set consisting of three transducers, with the first set arranged in pinwheel fashion about the load cell axis to measure the XY displacement components and torsional about the load cell axis.  The second set consists of the other three displacement transducers arranged about the load cell axis and extending in a direction parallel thereto and adapted to measure relative movement between the hub and housing corresponding to the applied forces parallel to the load cell axis and bending moments about the X and Y axes.  All of these transducers are disposed with their engagement tip in a common plane to minimize cross-influencing created by combined loadings.

Abstract: PROCESS FOR MAKING SOUND INSULATION            COMPONENTS           Abstract of the Disclosure A process for making composite contoured sound insulating panels of a type suitable for use adjacent to structural panels of automobile vehicle bodies, which in accordance with one embodiment of the present invention, comprises forming a fibrous pad incorporating controlled amounts of a heat curable thermosetting binder and a heat softenable thermoplastic binder distributed in a controlled manner therethrough.  The pad is subjected to a preliminary curing step to bond the fibers together into an integral mass, whereafter a dense liquid vinyl plastisol coating is applied to at least one face surface of the pad, which thereafter is heated to effect a fusion of the coating into a heat softened integral layer, effecting a simultaneous heat softening of the thermoplastic binder, whereafter the heated pad is placed between appropriately contoured mold surfaces and is compressed to impart a preselected contour thereto and localized emboss-ments therein and a desired surface finish to the plastisol layer, while simultaneously cooling the pad to effect a rigid-ification of the thermoplastic binder and the layer so as to retain the composite pad in the preselected contoured and em-bossed configuration.  In accordance with an alternative em-bodiment of the disclosed process, the pad is subjected to a preliminary molding step followed by the coating step and is subjected to a final molding step after the plastisol coating has been fused at an elevated temperature.

Abstract: ABSTRACT OF THE DISCLOSURE         A  coupler for toy and model railway cars includes a pivotable coupler member having a coupler knuckle to engage a complementary knuckle on an adjacent car.  The coupler member is mounted on support means for pivoting in a vertical plane between a lower position substantially parallel to a trackway and an upper position.  The coupler member is normally maintained in the lower coupling position by means of the magnetic attraction existing between two permanent magnets secured, respectively, to the coupler member and to the support means.          Cars may be uncoupled by providing a pole of an uncoupling magnet on the trackway to attract at least one pole of the coupler member magnet to torque the knuckle to the upper position and thereby uncouple adjacent cars.          The coupler knuckle includes a projection formed on its lower side which is adapted to engage and hold the adjacent complementary coupler knuckle when cars are being pulled in a normal running mode to prevent the knuckles from unintentionally disengaging when coupled cars pass over the uncoupling magnet.          The coupler member also includes an inclined ramp surface formed on the lower surface of a support shaft.  When a coupler member is in its upper position the inclined ramp surface is adapted to contact the fore end of the complementary knuckle to permit one car to push an adjacent car without the cars being coupled to one another.  Cars may be pushed to a desired location such as a track siding, and left by the pushing car without re-engagement or recoupling of the coupler knuckles.
