Abstract: The trimmed edges of cylindrical metal bodies are freed of internal burrs by shifting the body axially on the support means to move the burr-bearing edge from the cutting element to a cylindrical surface portion, following which an ironing tool flattens the burr against the surface so as to effect its fracture and removal from the body.

Abstract: A container end closure includes an end wall having a removable panel defined therein by a rupturable peripheral score, and a pull tab having a nose portion at one end, a handle portion at its opposite end, and marginal edge portions which extend generally toward the end wall and terminate short of the outer end of its nose portion. At least one depressed section is formed in the removable panel of the end wall to accommodate the terminal ends of the marginal portions of the tab, upon pivoting of the tab when the handle portion is raised. This construction ensures that initial contact with the panel is made by the outer end of the nose portion of the tab, thereby maximizing the effectiveness of force applied for score rupture initiation.

Abstract: Acarids, including spider mites, are effectively controlled by applying to the acarids, their habitat or both certain tertiary bis(halophenyl)phosphines, phosphine oxides and phosphine sulfides. These compounds kill adult and nymph acarids in addition to their eggs.

Abstract: Method in which an expandable internal shoulder forming member assembly to be used for forming a headpiece onto a preformed thin-walled plastic or laminate tube or bag provides a internal shoulder forming member upon which the loose fitting preformed thin-walled tube can be loaded. After tube loading, the internal shoulder forming member is inserted into a female forming member. Toward the end of the internal shoulder forming member's insertion stroke, a internal neck forming member which is mounted for axially movement within the head end of the internal shoulder forming member contacts the female forming member and then partially retracts into the head end of the internal shoulder forming member as the internal shoulder forming member continues to advance to the end of its insertion stroke.

Abstract: Photopolymerizable compositions and processes for photopolymerizing such compositions are provided, said process comprising admixing with said epoxides, photosensitive organohalogen compounds in combination with an organometallic compound and thereafter applying energy to the resulting mixture. The organohalogens decompose to liberate an active catalyst which then serves to initiate polymerization of the epoxide material. The organometallic compound functions synergistically with the organohalogen to enhance the film forming properties of the resulting polymer and or sensitivity of the polymerizable system.

Abstract: The use of photosensitive nitrones in an imageformation system, if desired with auxiliary compounds for intensifying the photolytically formed image or for improving the fixing of the image, wherein the image is fixed by the use of heat.

Abstract: Flow control apparatus and method for controlling the flow of gravity fed substantially cylindrical objects through a gravity runway wherein a starwheel, a star-shaped ferrous pulse rotor and a ferrous rotor are each spaced from each other and axially fixed to a free wheeling shaft mounted in a frame connected to a gravity runway such that the starwheel lobes jut into and rotate through the gravity runway. Each starwheel lobe engages each of a successive line of gravity cans as the cans fall through the runway. A magnetic sensor is mounted on the frame near the star-shaped pulse rotor such that as cans free fall past the starwheels and rotate the free wheeling shaft star points on the pulse rotor rotate past the sensor and disturb the sensor's emitted magnetic field. For each disturbance, the sensor emits an electrical pulse signal.

Abstract: Effective means for insuring predetermined axial spacing between parts in stacks, particularly in stacks of nesting, relatively large, thin-walled flexible parts and for maintaining positive alignment of the parts in stacks without causing undue difficulty when parts are being separated are provided. More specifically, plastic covers for plates or the like having specially constructed stack shoulders and stack stabilizers are provided.

Abstract: A trunk-style carton for ice cream and the like which displays greater ease in opening and superior protective properties for the product, after removal of a portion of the carton contents and reclosure of the carton, by virtue of a liner sheet beneath the carton cover which covers the upper surface of the carton contents completely and is adhered at one end to the upper portion of the inner surface of the carton back wall and at the other end to a zipper strip or a bonding portion of the inner surface of the carton front cover panel.

Abstract: A support member, for inclusion inside a film-wrapped package of moist and greasy food, comprising a semi-rigid thermoplastic core member printed on both sides with opaque ink distributed in substantially equal amounts on the two sides of the core and having a transparent protective overcoating of a polyolefinic resin or a varnish superposed on the printed core layer.

Abstract: A holder for supporting a hollow article includes a base, a plurality of resilient fingers extending outwardly from the base, and restraining means for maintaining proper alignment of the fingers. The resilient characteristic and the design of the fingers permits the loading and stable seating of a hollow article presented in misalignment to the holder, and the holder is especially useful for supporting can shells which, because of the nature of the operations to be performed thereon, often cannot be externally supported.

Abstract: Elongated closed bottom shells (cans) are produced in the preferred manner by a double-acting punch body arranged on a horizontal axis and reciprocated between opposed die stations at a substantially constant velocity by a hydraulic force alternately applied to opposite sides of a ram on the punch body; blanks (of cup form) are fed to the die stations at times when the punch body dwells at the end of a stroke. Preferably the applied force is such that punch body attains peak (maximum) velocity before the punch encounters a cup centered at the die station; cup feed, cup positioning, punch body travel and formation of a shell of correct length are monitored (sensed) and in the event a programmed condition of machine function or production criterion is sensed as not satisfied, the machine is stopped.
