Abstract: ABSTRACT TITLE:  APPARATUS FOR SECURING PIPE   In high-rise and mid-rise buildings wherein a concrete slab serves as a floor for one level and a ceiling for the level below it, it is necessary to secure vertical plumbing pipes to the slab wherein the plumbing pipes penetrate the slab through holes passing between the levels.  An apparatus for securing these pipes includes a first and second member.  Each of the members includes a base having a first and second end.  Each of the members including one or more ribs attaching perpendicular to the base and extending between the ends of the base.  The ribs on each of the members taper from the first end toward the second end of the base such that in side view each o r the members is wedge shape in cross-section.  The first member is located in the hole in the slab adjacent to the pipe by inserting from the top and the second member is located by so inserting through the bottom. This orients the members such that the large ends of their tapers are distal from each other.  The pipe is fixed to the hole by moving the members toward one another such that each slides upon the taper of the other, respectively.  This spreads the base of the first and second members such that one impinges against   the side of the hole and the other impinges against the side The members are fixed with respect to each other by suitable solvent welding techniques or the like to fixly maintain the pipe in its location within the hole in the slab.

Abstract: TRANSFLECTIVE LIQUID CRYSTAL DISPLAY               ABSTRACT OF THE DISCLOSURE    A transflective liquid crystal display is vlewable by either reflected or transmitted light.  The display utilizes at least one display cell of the guest dichroic dye-host liquid crystal material type, wherein the molecules are substantially parallel to the cell walls and have a helical twist in the inactivated state and are oriented substantially perpendicular to the cell walls in the activated state. A partially-reflective, partially-transmissive transflector element, which is non-depolarizing, is placed adjacent to the rear of the display cell and is followed by a light-retarding element, having its retardation axis placed at an angle, typically 45° to the polarization axis of a subsequent linear-polarizing element.  A light source, for use in the transmissive mode, is placed beyond the linear-polarizing element.

Abstract: ABSTRACT OF THE DISCLOSURE    For progressively breaking-in-place concrete of roadways or the like, a vertically extending diesel power driver, of a type used as a pile driver,but with a concrete-breaking shoe forming its lower end,is advanced by a towed chassis.   Guide angles at the upper portion of the power driver, cooperating with a guide bar vertically disposed,guide the power driver in its conventional rythmic bobbing, with sufficient loosness to permit the power driver to have a pendulum like swinging action.  This swinging action results from relatively intermittent movement of the bottom portion of the power driver while the top portion is advanced more steadily by the chassis.   Shoe towing means extend forardly from the shoe to a hanging link which is resiliently biased forwardly to tow the shoe.  The biasing is provided by long-throw cushions. The forwardly extending shoe-towing means is flexible,  to prevent damage when the shoe is driven deeply.  The guide angles have moder-ately long, slightly convex faces to withstand pounding by the guide bar.

Abstract: ELECTRIC FUSE AND FUSIBLE ELEMENT THEREFOR                   ABSTRACT           For interrupting all values of electric current in a high voltage circuit which cause operation of a fuse within one hour,  a plurality of parallel connected helically configured fusible elements formed of cadmium are embedded within quartz sand in granular form disposed within a housing structure which includes a tubular member of insulating material to the ends of which terminal caps are secured and connected to the ends of the fusible elements respectively so that currents of a high order of magnitude are interrupted in a fraction of a half cycle in a current limiting fashion and so that currents of a low order of magnitude and which are slightly in excess of normal rated load current of the fuse cause the temperature of the fusible elements to rise to the melting point within a longer predetermined period of time and then to establish a gap sufficient to withstand the recovery voltage.  For substantially preventing degradation processes in /  the cadmium fusible elements, a non-porous metallic coating of substantially uniform thickness between 0.5 and 10 microns is arranged to cover each fusible element and wherein there is substantially no inter-metallic diffusion through the interface between the cadmium fusible elements and their metallic coatings at temperatures below the melting temperature of cadmium.

Abstract: ABSTRACT          An inwardly offset surface of the cover of a carton is cut in a plane transverse to the top of the cover.  A protrusion on the bottom surface of a complementary recess in the latch flap extends through the hole to latch the carton with the protrusion being within the cover recess to prevent accidental opening of the carton.  The mold for producing the carton cuts the hole thermoforming by relative movement between a male key mounted in the male mold member and a female key mounted in the female mold member.  Both keys have flat surfaces transverse to the closing motion of the molds.  These flat surfaces are biased into engagement one with the other so that the plastic is cut in a shearing action.

Abstract: Abstract of the Disclosure A stretch wrapping system including apparatus and process is disclosed in which rotation of a non-cylindrical or off-centered load draws film web at a continually fluctuating speed from a film roll through a prestretching device to wrap the load.  The prestretching device includes an upstream roller coupled to a braking device and a downstream roller coupled to a positive torque device.  The speed of the downstream roller is proportional to the take-up speed of the web on the load and the feedback device continually senses the speed of both rollers and adjusts the braking device so that the speed ratio of the rollers produces a constant stretch of the film web above its yield point.  The feedback device also continually senses the forces contri-buted by the braking device and the torque device and continually adjusts the torque device so that the force on the web between the downstream roller and the load is held constant at a level below the yield point of the web.  The feedback device may be connected to display systems to display the amount of web stretch, the web force to the load, and the amount of film web consumed in a wrapping operation.

Abstract: IMPROVED DRIVE MECHANISM FOR A                 ROTATABLE SWEEP ARM             Abstract of the Disclosure An improved drive mechanism for rotating a sweep arm in a storage structure that contains a free-flowing stored material.  The inner end of the sweep arm is mounted on a turntable that is disposed in the inner end of a radially extending trough in the foundation of the storage structure.  The turntable is provided with a pair of spaced, concentric, downwardly extending flanges, and a plurality of ribs connect the upper portions of the spaced flanges.  The spaces between the ribs define upwardly diverging passages.  A drive pin is positioned beneath each rib and extends between the spaced flanges.  The teeth of a drive sprocket are engageable with the drive pins, and rotation of the sprocket acts to rotate the turntable and thus rotate the sweep arm around the structure to dislodge the stored material.  As the drive sprocket rotated, any stored material in the vicinity of the drive pins is extruded upwardly through the passages by the sprocket teeth to prevent possible jamming of the drive mechanism. In addition, the roots of the sprocket teeth are provided with relief and the sprocket teeth are tapered to aid in the removal of the stored material from the drive mechanism.
