Abstract: Thermoplastic film bags or like packaging sections with or without hanger holes are stacked and welded into pads from which individual bags are easily hand-torn for use. Bag sections, each with a hanger portion and having an arched cut in one wall, are produced three at a time from a continuously longitudinally sub-divided and side seam welded, wide flattened film tube stock web, after incising the cuts at three transversely spaced places in one layer; the sections are stacked and at the hanger parts welded into a pad, and the pad is transversely perforated through the incised arched cuts and hanger holes punched in the hanger part.

Abstract: Method for processing Euphausia superba, a large-sized animal plankton of 15-50mm body length which is quite similar to the small shrimp, Sergestes lucens, in dimension, shape and taste. This method basically comprises applying, to a mass of fresh bodies of Euphausia superba, an appropriate force whereby from the head-chest portion of each body there may be readily expelled the internal organs, above all the liver of objectionable taste, leaving the desired meat of the tail-belly portion within the shell then subjecting the mass of the bodies of Euphausia superba so treated to the steps of heating in hot or boiling water to effect protein thermal coagulation in most of the proteins of the meat portion, removing the juices produced in a gap formed between the shell and the thermally shrunken meat portion, freezing quickly each separate body, without adherence to one another, to a temperature of about -35.degree.

Abstract: A valving device for inclusion in a pair of lines delivering hot and cold water to a point of mixed flow use having respective flow valving sections including respective aligned valving members joined as a shuttle unit, secured to and extending through flexible diaphragm means isolating the sections, and longitudinally shiftable to decrease flow area in one section while increasing flow area in the other; each section having a flow constriction as a fixed resistance between the diaphragm means and a respective valved flow space, whereby upon change of the relation of supply pressure and consequent tendency to change flow ratio from a pre-existing relation, the shuttle shifts to null the difference of forces acting thereon in the two sections and thereby re-establish the flow ratio; a hot inlet temperature responsive override being includable.

Abstract: A system for transfer of liquid from a storage vessel to and maintaining at least a minimum level in a receiver or plurality of receivers, using the gas arising from liquid vaporized into the gas space above the liquid in the storage vessel to expel liquid through a valve energized by the gas and responsive to gas-back pressure type probe means utilizing the gas. A clustering manifold device applied as a vessel closure provides a liquid manifold valve for four controller devices valving liquid to respective receivers, and a gas manifold provides gas supply connections for supplying gas at pre-established pressure to energize respective controller devices and associated gas probes.

Abstract: A method for continuous fabrication of bags from a longitudinally advanced two-layer thermoplastic film web fed tangentially onto a rotating drum for carrying out transverse web seam welding and severing, with high speed operations facilitated by tensioning the web as it is being fed onto the drum, and with web tension release just before or as the seam welding is effected to ensure good quality seaming.

Abstract: Liquid level in a vessel of cryogenic liquid or solid-liquid slurry is determined and indicated by sensing, in an immersed tubular probe, a probe-evoked vapor gas pressure counter balancing the hydrostatic head to the probe tip, and displaying an output on an appropriate meter scale or by a digital readout device in level height or other vessel-content terms, and, if desired, activating a low level alarm; the probe as a heat pipe conducting heat, from a source external of the liquid, to the probe bore as far as the tip to volatilize liquid entering the probe tip from which as a sensing gas the gas phase may slowly bubble; a differential pressure sensing device being connected to the probe and to the vessel gas space for a closed vessel.

Abstract: A side-seamed two-panel thermoplastic film bag suited for packaging printed matter, having an open mouth to be transversely seam-sealed closed after initial filling with one panel end projecting beyond the mouth as a suspension portion with wicket-accepting hanging holes, and an extension of the second panel at the other end reflected onto the first panel as a bag closure flap with lateral ends secured to the other panel by the side seam-welds, the flap having oblique tear perforation lines up from the bottom corners, a permanently tacky adhesive stripe between the perforation lines releasably bonding the flap to first panel, whereby the closure is easily hand-torn and opened for content inspection and re-closure by the adhesive.

Abstract: High production rates and decreased wear and tear and stress on parts are obtained in a bag fabrication machine with the web fed intermittently by respective bag lengths, for operations such as perforating, transverse severing or welding with the web halted.A sector plate is oscillated between two extreme positions faster in one direction than in the other by a flywheel-carried crank pin orbiting about an axis eccentric from the plate axis; the pin engaging a block sliding in the plate radially of its axis. The plate motion is applied as input to an electrically operated clutch and brake unit and the output is applied to web advance rolls. Switches on the slide block, actuated at the extreme sector positions, control the alternating clutch and brake engagement to drive the rolls for web feed during the slower sector motion of relatively longer duration; and also declutching with braking to halt the web precisely, for and during a faster sector plate return motion.
