Abstract: A process and machine, as a separate or integral part of a process and machine for manufacturing glassware, plastic or similar articles, adapted for the specific purpose of simultaneously cutting off excess ends of hollow glass, plastic or similar articles such as tubes enlarged at their mid-portion, comprising means for rotationally supporting the mid-portion of said articles either vertically or horizontally; thermal, electromagnetic or mechanical cutting means movable into and out of cutting relation with the excess ends of the article, rotatable grippers synchronized with the supporting means for rotationally gripping one or both excess ends during cutting of same and being adapted to exert a slight outward axial force at a predetermined rate on said excess ends until the cutting action is completed, and to release the excess ends to gravitate to a scrap collector before or after removal of the finished article.

Abstract: Improved system for controlling the movement of rotary article conveying mechanism in IS glassware forming machines employing a reversing arm, operating mechanism for said arm to move same between a parison forming station and a blow molding station, said operating mechanism including a double action fluid driven actuator, solenoid controlled valves for the actuator, an arm position sensor, an actuator pressure sensor, a logic circuit receiving signals from the sensors, a digital valve responsive to signals from the logic circuit for fluid flow control from the actuator, a regulator controlling fluid pressure to the actuator, and a control panel containing digital indicators, mode switches and a mode indicator and a digital display for reception and transmission of signals to and from the logic circuit, the end result being the precise timing of reversing arm operation and elimination of impact at the end of reversing arm movement, with identical operational mechanism for the take-out arm, with the additional

Abstract: Improved system for the fabrication of preforms used in the production of glass containers in I.S. machines, employing the blow-blow process to reduce the time delay of mechanical movement between the stages of crown formation and commencement of counterblowing, and the increase in counterblowing or molten glass gob inflation, thus improving glass distribution in the walls of the preform as well as in the finished container, resulting in an improved quality container and in increased production.

Abstract: An electronic glass gob distributor for machines which form glassware, thermoplastic or similar articles, comprising one or more glass gob distributing channels each supported on its rotatable shaft, a step motor for actuating each rotatable shaft to move the associated distributor channel toward respective forming stations, a pulse signal generator for each step motor, a pulse amplifier for each glass gob distributor channel to amplify and feed the pulse controlling signals to the respective step motor, and a microcomputer programmer for controlled sequence of the generated pulse signals eminating from a data processing unit connected to an operator's control panel, with suitable conductors from the data processing unit to gob feed sensors and to distribution channel position sensors, with additional conductors to solenoids operating a pneumatic valve adapted to actuate a fluid operated linear motor for moving rejecting channels into gob receiving position to prevent feeding of a gob into the glassware formi

Abstract: A releasable magnetic attachment for underwater diver's hose and the like utilizing pneumatic, hydraulic or electromagnetic release actuating means operable by the diver or by an operator on a tender on the surface of the water, or a manual release operable by the diver underwater.

Abstract: A reciprocating hot gas engine adapted to provide a self-starting, controlled expansion, and a long time working fluid heating inside heaters placed in a combustion chamber separated from the engine compression and expansion cylinders of the engine.

Abstract: A reciprocating internal combustion engine adapted to provide a selfstarting, controlled expansion and a substantially constant volume combustion in combustion chambers separated from the engine compression and expansion cylinders of the engine.

Abstract: An underwater cutter for submerged pipelines employing O.sub.2 or gaseous hydrogen fluoride and a continuously fed electrode to provide high temperature cutting means, said electrode being carried by a motor driven spool in a housing on rollers contacting the pipe, one of said rollers being electrically driven, an adjustable bracket carried by the housing and having rollers substantially opposed to the first mentioned rollers, a knife edge carried by the housing adapted to ride in a precut slot on the pipe for guiding the cutter about the pipe, with suitable connections on the housing from a power source, a compressed air source, a source of O.sub.2 or gaseous hydrogen fluoride, a welding cable, and a ground connection.

Abstract: Coupling for replacement or repairs in pipelines of all categories and of specific utility in vertical submarine pipeline risers so designed for rapidity and simplicity of installation in restricted areas because of its reduced size in addition to its effective sealing characteristics. A coupling that can be readily and simply disconnected and reinstalled without special tools or procedures.

Abstract: A clamp for the permanent repair of leaking underwater pipelines providing improved sealing qualities against high pressures, as well as a feature which is designed to decrease the erosion of submerged pipelines which are subjected to erosive action of abrasive materials such as sand, fine gravel or silt in motion and providing for relatively easy and rapid installation under adverse diving conditions.

Abstract: A coupler for joining the ends of pipes and ducts used for liquids and gaseous fluids, such as are carried in pipelines and the like, particularly where used in underwater locations, the coupler providing for angular relation between adjacent pipes to follow the contour of the bottom on which placed, the construction of the coupler facilitating its placement and providing a positive seal against leakage.

Abstract: A tubular clamping and sealing coupler for underwater oil or gas pipelines or the like operating under high pressure, providing a fluid-tight joint between the sections of the pipelines, one section of the coupler being firmly secured to the pipe on which it is mounted while the other section of the coupler is mounted on the adjacent pipe and is tightened into sealing and clamping position against the first mentioned coupler, a single operation performing the clamping and sealing and coupling function, said coupler eliminating the need for precise alignment of the pipes or use of a chemical sealing compound.
