Abstract: ABSTRACT          This invention relates generally to a method and apparatus for molding a centrally apertured part, such as a video disc.  Prior art molding techniques are deficient in that extremely tight hole centering tolerances could not be met, and likewise thickness tolerance caused excessive birefringence of a light beam used in reading the disc.  The present invention overcomes these deficiencies by providing an improved molding technology   In accordance with the invention heated material is injected into an annular cavity, defined by a pair of mold halves, through a sprue passage, defined by a sprue bushing and an end  portion of a punch.  The annular cavity and the sprue passage form, respectively, the centrally apertured part and a sprue.  After partial cooling of the heated material, the punch is locked in place while the annular cavity is displaced relative to the sprue passage so that the sprue is severed from the part along the peripheral surface of the punch end portion.  The mold halves are separated to open the annular cavity while the sprue is resting on the punch end portion, and while the part is held by the punch end peripheral surface. After the mold halves are separated, a sprue ejector member is actuated to eject the sprue from the punch end portion.  The finished video disc is then removed, carried by the moving platen of the moving mold assem-bly.  An improved injection gate is also provided, as well as a unique manner of cooling the mold assembly.

Abstract: ABSTRACT   The present invention relates to a cup separating device for use in a beverage dispensing vending machine.    The device comprises a fixed body with an opening through which cups may pass.  Two cup-supporting arms are pivotally mounted about   vertical axes on the body and lie on opposite sides of the opening.  Two pairs of cup-splitting arms are also pivoted on   vertical axes above the cup supporting arms and lie on opposite sides of the opening.  An actuating member is mounted on the body for sliding movement between first and second positions.  It carries camming means for swinging the supporting arms and the splitting arms about their vertical pivot axes as the actuating member is moved.  In the first position the cup supporting arms support the cups below the rim of the bottom cup and the cup-splitting arms are clear of the stack of cups.  As the actuating member is moved towards the second position the pairs of cup-splitting arms are moved to engage below the rim of the cup next above the bottom cup and then the supporting arms are moved outwardly away from the stack of cups.  Finally a projection engages between the arms of each pair of splitting arms to force them apart in the vertical direction and thus prise the lowermost cup from the stack.

Abstract: ABSTRACT OF THE DISCLOSURE      In a control apparatus for a machine tool, a resolver interface circuit is utilized to determine whether or not the axis motors have driven the machine tool to the selected position.  The resolver interface circuit synthesizes sine and cosine wave forms which are applied to a resolver which is mechanically coupled to the corresponding axis motor.  The resolver interface circuit also synthesizes a signal which is phase related to the resolver excitation wave forms by the selected rotational displacement of the resolver and axis motor shafts required to achieve the selected position for the machine tool.  The phase related signal and a positional feedback signal from the resolver are compared to generate an error signal to the driver for the axis motor.  The selected position can be each incremental step where the axis motor is a stepping motor.

Abstract: METHOD OF AND APPARATUS FOR HEAT PROCESSING         OF PULVERIZED SOLID FUEL                 Abstract of the Disclosure According to the invention pulverized solid fuel is pro-cessed by heating the fuel to a temperature at which thermal decomposition of the fuel begins and subsequently heating the fuel to a temperature at which an intense thermal decomposi-tion of the fuel takes place to form a vapour-and-gas suspension containing pulverized particles, gas, tar vapours and pyrogenic water vapours. The resultant vapour-and-gas suspension is cooled in a chamber by water and/or pyrogenic water to a temperature from 360 to 140°C at which pulverized solid particles adsorb heavy tar. To obtain the resulting product in the form of a pulp, the vapour-and-gas suspension is cooled for a second time to a temperature from 80 to 20°C at which the fractures of intermedia-te and light tars are condensed.      Combustion heat of the resulting solid matter is higher. than that of the product obtained by a conventional method, in addition, it may be conveyed by a water channel. the result-ing product in the form of a pulp may be conveyed by a water channel directly to the consumer. When practising the method, such side product as pyrogenic water is utilized which is usually purified prior to disposal.

Abstract: ABSTRACT      A transparent thin bottle-shaped container is produced by means of biaxially oriented blow molding of a cylindrical piece with a bottom of polyethylene terephthlate material.          Multiple pieces are molded by every cycle of an injection molding machine.  The multiple pieces thus formed are held at the gate integrally projecting therefrom, by a base plate moved forward at the front of the mold in the injection mold-ing machine and then conveyed to a gate cutting unit provided to one side of the injection molding machine.  The pieces thus cut from the gate by the cutting unit are sequentially conveyed onto a conveyor.  The pieces are gradually cooled from the hot molded temperature during the conveyance and are additionally cooled, while being conveyed on an oblique conveyor installed with a cooler, to room temperature or lower predeter-mined temperature.  The cooled pieces are then re-heated by a heater immediately before a biaxially orientation blow molding process.

Abstract: HAROLD W. STILLMAN METAL LADDER AND METHOD OF FABRICATING THE SAME File No. 86-512 ABSTRACT OF THE INVENTION      A metal ladder is fabricated from a pair of spaced rails in which the rails have web portions which are provided at spaced intervals with inwardly directed embossments.  Each of these embossments has an opening into which one end of a tubular rung is inserted and swaged to the rail.  The embossments act as ribs to carry the load toward the flanges constituting the stiffer portions of the rail thereby increasing the strength and effec-tively reducing the web flexure and angle changes between the rungs and the rails, due to sideward forces in ladder use.  By reason of the built in stiffness web thickness may be reduced resulting in savings in materials.  Additionally, intermediate these embossments, just described, the web portion of each rail is formed with one or more outwardly directed embossments.

Abstract: ABSTRACT         A pressure vessel comprises a rigid envelope enclosing a chamber and consisting of a body and cover, the rim of the cover being inserted in the rim of the body, and the body and cover being secured to each other.  Defined between the overlapping rims is an annular groove adapted to receive a flange at the periphery of a circular flexible diaphragm, which serves to divide the chamber into two compartments of variable volume.  There is a fluid orifice in both the body and cover, the two orifices being axially aligned and communicating one with each variable volume compartment.  To ensure a good seal between the compartments, and to enhance retention of the flange in the groove, the annular groove is of less height and greater width than the flange on the diaphragm, before the flange is sand-wiched into the groove between the rims of the cover and body, so that the flange is deformed into the groove, when the cover is assembled on the body.  The rims on the cover and body may be shouldered for good co-operation therebetween and the shoulder reinforced on the outside of the vessel so that it does not collapse when the vessel is pressurized.
