Abstract: A method of economically producing a relatively rapidly soluble machine handleable particulate composite material from a material of relatively low solubility comprising pulverizing a material of low solubility, selecting a first appropriate size fraction from the pulverized material and mixing the selected fraction with a predetermined proportion of water to obtain a composite. The composite is dried at a predetermined temperature for a specified time. The dried composite is pulverized and a second selected appropriate size fraction is obtained. The second size fraction possesses increased solution solubility and machine handleability properties over the starting relatively low solubility material.

Abstract: Apparatus for moving newly formed glass containers from a cooling dead plate to a moving machine conveyor in which the ware is engaged by a finger, with the finger being generally horizontal and engageable with the container at a point on its sidewall which best suits the moving of the container by a sliding motion. The finger, or fingers in the case of plural containers being simultaneously moved, is moved through an arc approximately 90.degree. with respect to its vertical axis, moving the containers from the dead plate to the conveyor and then the finger is retracted out of contact with the containers on the conveyor. After retraction, the finger-mounting mechanism which takes the form of a generally horizontally disposed cylinder is moved back through 90.degree. to a position opposite the position of a dead plate where the finger is then again moved outward and rotated about the axis of the cylinder mounting. In this fashion the containers are moved onto the conveyor.

Abstract: Glass containers received on a machine conveyor which passes a plurality of forming machine sections and receives the ware from the sections is coordinated in its relationship to the machine sweepouts, such that a gap is provided periodically in the row of ware carried by the machine conveyor. A bottle-transfer device which transfers the ware from the machine conveyor to a cross-conveyor is operated so that it also will maintain the gap that is provided in the line of ware. The ware on the cross-conveyor moves in line across the open-receiving end of the lehr and is pushed from the cross-conveyor onto the moving lehr mat. By providing a gap in the line of ware, the lehr loader pusher bar may be operated more slowly than in the past and to thereby provide a more stable transfer of ware from the cross-conveyor to the lehr.

Abstract: Method and apparatus for forming glass containers by the blow and blow process in which a parison mold and blow mold are positioned relative to each other, such that parisons can be transferred by an invert arm. The parisons are formed with their necks down in the parison mold from a charge of glass delivered thereto, and vacuum is applied to the neck mold to settle the molten glass in the neck mold about a special neck pin to thereby form the finish portion of the container. The neck pin is pulled and counterblow of the charge into parison form is accomplished and the parison is transferred from the parison mold to the blow mold where it is expanded into final shape. The parison mold is coated with a "solid film lubricant" which provides a surface that has an insulating effect and requires less "swabbing" over its useable life.

Abstract: A driving and addressing circuit for applying sustaining, writing and erasing voltages to the cells of a multicelled gas discharge display/memory panel. The voltage generating circuitry is isolated from each panel electrode by a pair of oppositely poled diodes individual to that electrode. The diodes provide low impedance paths for the sustainer current and isolate the electrodes from each other. The writing and erasing voltages are coupled to the electrodes through a plurality of complementary MOSFETs, one per electrode, which eliminate all but one of the diode switch circuits per electrode array of the prior art circuitry. The P-channel and N-channel MOSFETs can be formed on separate integrated circuit chips with one of the pair of the diodes while the other diodes are formed on common anode and common cathode integrated circuit chips. In addition, a portion of the addressing circuitry can be formed on the MOSFET chips.

Abstract: A laser detection system for detecting parisons or portions of parisons remaining on cylindrical core pins at an ejection station. Injection molding of tubular parisons around cylindrical core pins occurs at a molding station; cooling the parisons while supported on the core pins occurs at a cooling station; and then, axially stripping the parisons from the core pins occurs at an ejection station. The parison stripping step is accomplished by a horizontally reciprocable carriage which is selectively moved into and out of vertical alignment with a set of core pins and parisons positioned at the ejection station. Sectional gripping members on the carriage are radially closable when in alignment with the parisons, to grasp the parisons for their axial removal from the core pins upon the horizontal displacement of the carriage.

Abstract: Disclosed is a lid for a container which is designed to allow drinking of the contents while the lid is in place and to prevent spillage of the contents. The lid includes a generally circular body member and a sealing edge located along the periphery of the body member. A raised platform is integrally formed on the body member and is bounded by the periphery of the body member and an upstanding wall portion generally defined by a chord of the body member. A flipper valve is located on the platform and is generally radially aligned and hinged near the wall portion. The valve includes an integrally formed protrusion which provides a place for application of downward pressure to open the valve. The valve is such that lip pressure is sufficient to cause the valve to open. The platform provides a flat area extending to the edge of the container which allows the lip to make a complete seal over the portion of the lid which it contacts.

Abstract: There is disclosed a solar energy operated system and method in which a quantity of liquid media is placed in solar collectors and heated to a preselected temperature therein. Upon reaching this temperature, the liquid is transferred to a first storage vessel. The liquid is replaced in the collectors from a separate second storage vessel. The hot liquid is drawn from the first vessel and circulated to a heat exchanger of a heat operated device, such as an absorption refrigeration device or a space heating device, and heat is exchanged thereby to operate such device. The liquid is returned from the heat exchanger of the device to the second storage vessel so as not to thermally contaminate the higher temperature liquid processed by the solar collectors. This is termed a batching method of operating the solar energy collectors in the system.

Abstract: A method and device for assembling pre-shaped pairs of coaxially mating parts in interfitting assembled relationship one within the other and briefly embodying the concepts of rotating the mating parts in unassembled positionally oriented relationship through a first arcuate path with the corresponding interfitting portions thereof disposed transversely of their respective rotational planes and in adjacent confronting relationship with one another, and concurrently rotating an axially elongated assembly member in rotational synchronization with the mating parts and through a second arcuate path deployed in adjacent oblique planar relationship with the arcuate path of rotation of the mating parts to thereby direct the assembly member to travel along an arcuate path disposed to cause the assembly member to uniformly advance and retreat relative to the arcuate path of rotation of the mating parts and during such advance to forcefully urge the mating parts into assembled interfitting relationship one within the o

Abstract: This invention relates to a system of determining which of a plurality of molds produced a particular container. A concentric ring code is molded into the bottom of each container as it is produced. The containers are then passed by a reading station, where light whose intensity is proportional to the angle of incidence is projected onto the bottom of the container. Readings are taken of the variation of intensity of light reflected to a particular point in order to determine the position of rings on the container. Suitable electronics then decode the ring position to determine the container code, thus allowing identification of the mold which produced each container.

Abstract: Method and apparatus for cutting tubular material with two separate laser beams having a constant power ratio by using a laser source having a single output beam of random polarization. A beamsplitter is positioned so that the output of a laser source strikes it at a near normal angle of incidence. The beamsplitter divides the laser beam into two components whose power ratio remains relatively constant due to the near normal angle of incidence of the laser beam onto the beamsplitter. The two components are then directed to strike the tube. The constant power ratio permits the most efficient use of the power of the laser source.
