Abstract: METHOD AND APPARATUS FOR THE MANUFACTURE OF GLASS            ABSTRACT          This invention relates to a process and an apparatus for the manufacture of fused glass, suitable for molding, wherein the total time of manufacture is reduced to about one hour.  The process accelerates the homogenization and refining of glass by eliminating unfused particles and gas bubbles which are the main factors limiting the production rate of industrial glass.  This is accomplished by increasing the temperature of the molten glass to produce foaming throughout its mass while maintaining its viscosity below 1,000 poises.  This divisional application is specifically directed to an improvement in all apparatus for rapidly refining glass of the type having an elongated continuous channel in which a molten vitreous mass is introduced at one end thereof, flowed horizontally therethrough and subjected to an expansion of at least 50% of its initial molten volume by foaming the molten mass throughout its entire volume as the mass moves along the channel from its one end to the other end, said improvement comprising heating means disposed longitudinally along said channel and in said foaming zone below the surface of said vitreous mass for rapidly heating the flowing vitreous mass to cause its entire volume to pass totally to the foam state and expand by at least 50% of its initial volume.

Abstract: A B S T R A C T Load weighing devices for cranes, used to measure the weight being carried by the hook of the crane at a particular instant, generally include a dynamometer which operates to measure the load tension in the rope, and a safe load indicator which indicates the maximum load which the crane can safe-ly carry.  The signal from the dynamometer is compared either manually or automatically with the signal representing the maximum load.  A disadvantage of existing systems is that, due to frictional effects in the various sheaves and to rope bending losses, the dynamometer gives a different reading accord-ing to the direction of rope motion.  This invention is directed to overcoming this disadvantage by the provision of a rope direction sensing element for sensing the direction of rope motion through the dynamometer.  The dynamometer output signal is then modified in accordance with the direction of rope motion.  In addition, the dynamometer output signal is modified in accordance with the number of falls of the rope.

Abstract: Abstract of the Disclosure This invention improves the quench efficiency of appa-ratus for tempering flat or curved glass sheets suspended in a vertical orientation.  Such apparatus typically includes a plurality of nozzle boxes each pivotable about its longitudinal axis and adjustable in position to provide a pair of sets of nozzle boxes facing the opposite major surfaces of a glass sheet held in a quenching position between two sets of nozzle boxes.          The present invention requires a minimum of power to obtain optimum heat exchange from blasts of tempering fluid applied against the opposite major glass sheet surfaces.  This is achieved by simultaneously pivoting the nozzle boxes so that they oscillate in unison about their longitudinal axes a limited angular displacement from a predetermined, adjusted orientation at which said blasts are directed approximately normal to an opposite glass sheet surface portion through an angular dis-placement not exceeding 20 degrees thereby to optimize the heat exchange effect of the moving blasts of tempering fluid applied via the nozzles of said nozzle boxes against the opposite major surfaces of said glass sheets that are quenched.

Abstract: ABSTRACT OF THE DISCLOSURE         A biaxially oriented molded bottle of a saturated polyester, especially polyethylene terephthalate, exhibits various superior character-istics as a bottle container.  However, because of its lack of mechanical strength, its use as a pressure bottle has been regarded as impossible. According to the invention, the lack of mechanical strength is compensated for by slightly increasing the wall thickness of the bottle, and molding its bottom portion such that the deformation of the bottom portion in an outward curve by the action of the internal pressure of the bottle is inhib-ited by the outwardly curved deformation of other parts, and forming the bottom portion as a simply protruding structure acting against the direction of internal pressure.

Abstract: ABSTRACT OF THE DISCLOSURE    A pilot hole of a preselected diameter is drilled with a suitable bit in an earth formation to a desired depth.         The bit is withdrawn from the hole, and an expandable hole opener or underreamer run in the pilot hole with its cutters fully retracted and closely adjacent to each other.  When the depth is reached at which enlargement of the Pilot hole is to commence to produce a blast chamber, the cutters are forced laterally outwardly by fluid pressure while the hole opener is rotated, without moving the hole opener axially of the pilot hole, to cut the wall of the pilot hole and increase its diameter to the extent determined by maximum expansion of the cutters, thereby forming the upper end of the enlarged blast chamber.  Rotation of the hole opener continues while it is progressively lowered to drill the blast chamber down to the bottom or lower end of the pilot hole, the bottom of the blast chamber produced by the hole opener lying in substantially the same plane as the bottom of the pilot hole to collectively form a single blast chamber bottom.

Abstract: SURGICAL STAPLE               ABSTRACT OF THE INVENTION    A surgical staple for use in suturing the skin or fascia of a patient.  The surgical staple has an elongated, substantially horizontal crown portion terminating in downwardly depending leg portions having points formed at their free ends.  The staple, together with a plurality of identical surgical staples, is adapted to straddle and to be fed along a guide means of a surgical stapling instrument to the anvil thereof.  The crown of the surgical staple is formed about the anvil by the surgical stapling instru-ment former which bends end portions of the surgical staple crown downwardly so that the staple leg portions are substantially coaxial with their points approaching each other.  The surgical staple has a first pair of diametrically opposed flats extending respectively along the front and rear of the crown and leg portions.  The surgical staple has a second pair of diametrically opposed flats, disposed at 90° to the first pair of flats.  One flat of the second pair extends along the upper surface of the staple crown portion and the outsides of the staple leg portions and the other flat of the second pair extends along the underside of the crown portion and along the insides of the leg portions.  The flats of the first pair, cooperating with similar flats on adjacent surgical staples, assure proper feeding of the surgical staple along the surgical instrument guide means.  The flats of the second pair, cooperating with the surgical stapling instrument former and anvil, prevent undesirable rotation of the staple crown portion during forming and implanting of the surgical staple.

Abstract: ABSTRACT          PREPARATION OF POLY(ESTER CARBONATE) BY            INTERFACIAL METHOD            Poly(ester carbonate) polymers are prepared by reaction of bifunctional phenolates in an aqueous phase with phosgene and with the acyl halide of a bifunctional carboxylic acid halide such as terephthaloyl chloride in an organic solvent such as dichloromethane.  At least a portion of the phosgene is reacted with the phenolate before or during reaction of the acid chloride with the phenolate to avoid the formation of polyester blocks which have limited solubility in the organic solvent.  After reaction is complete, or at any stage wherein oligomers are formed, the aqueous phase can be cleanly removed and easily separated from the organic phase, and the organic phase readily washed free of by-products.  The final polymer product is recovered from the washed organic phase and is colorless, substantially amorphous and melt processable, and has a high glass transition temperature.

Abstract: ABSTRACT   Two waveform traces to be simultaneously displayed are sampled and converted to a series of digital sample values.  An electro-optic display, e.g. a liquid crystal or electroluminescent display has a first m set and a second n set of electrodes arranged in a matrix having m x n display elements.  The matrix may be in cartesian XY or r .THETA. polar co-ordinate format.  In one form the m set of electrodes are arranged in two subsets alternating with one another forming a subset mo of odd rows and a subset me of even rows.  Coded waveforms Vi, each having a different shape over a period T are applied to one subset mo of the m electrodes whilst another voltage is applied to the other subset me of m electrodes followed by application of Vi to the subset me and the other vol-tage to subset mo.  Selected ones of the coded waveform Vi are generated and applied to the n electrodes, the choice of such selectively produced waveforms being related for each successive n electrode to successive samples values of the two traces and the order of coded waveforms on the m set of electrodes.  As a result traces are displayed at intersections where the same waveform occurs periodically and simultaneously.  The coded waveforms Vi applied to the m electrodes may be produced by a pseudo random generator.  The selected ones of the coded waveforms Vi applied to the n electrodes may be produced by a read only memory supplied with trace sample values stored in a random access memory. A priority encoder modifies each sample value of the traces as necessary to ensure that two values for any given n electrode do not appear on the same sub-set of m electrodes.

Abstract: ABSTRACT A passive dosing dispenser for issuing, for example, a predetermined volume of a liquid toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. The dispenser employs no moving parts, and acts in response to the lowering of the water level in the toilet tank to dispense the liquid solution at a point in the flush cycle when it can be most effectively utilized.  The liquid solution in the dispenser is maintained in an isolated condition by means of air locks from the toilet tank water surrounding the dispenser regardless of the depth to which the dispenser is immersed in the tank during quiescent periods inter-mediate flush cycles.  A preferred dispenser embodiment comprises an air pump portion where air is trapped by rising tank water, the air being forced down against liquid solution housed within a liquid collector portion of the dispenser.  As the tank water level continues to rise, it increases the air pump's driving head, thereby forcing the liquid solution acted upon by the pump to a level sufficiently high to fill a measuring pocket located adjacent an expansion chamber portion of the dispenser.  The air pump also serves to supply air to the upper reaches of the non-vented liquid solution reservoir, thus partially vitiating the vacuum created within the upper reaches or head space of the reservoir by discharge of the liquid solution.  The liquid solution level continues to rise in the expansion chamber adjacent the measuring pocket until such time as an air vent in fluid communication with the expansion chamber is blocked by the rising water level in the toilet tank.  Because the air vent in fluid communication with the expansion chamber controls the height to which the liquid solution rises in the expansion chamber, it is critical that the air vent be so located as to permit the measuring pocket to be filled with the liquid solution to be dispensed during each pumping cycle of the dispenser, yet not so high as to eliminate the air-lock which is formed in the uppermost reaches of the expansion chamber. In fluid communication with the bottom of the measuring pocket is an inverted J-shaped syphon tube which is utilized to withdraw a predetermined dose-volume of liquid solution from the measuring pocket during each flush cycle. r EKL:ph
