Date Jul. 11, 1996The present invention provides a method and apparatus for packaging goods from a continuous stack. A conveyor is arranged on a base to move the continuous stack in a conveying direction. A separator means separates a stack portion of a predetermined size from the continuous stack. The stack portion is pushed aside from the conveying direction to a position within reach of a gripper. The gripper is used to transfer the stack along a second direction to at least one packaging position in a box or on a packaging blank. The gripper comprises at least two jaws which compress and hold the stack during the transfer. The gripper is arranged parallel to the base so that the base supports the stack portion from below during the transfer. In the method of the present invention, the stack portion is moved onto a cover part of a packaging blank and the packaging blank is folded around the stack portion to form a box.

Filed: 1986-06-18
Abstract: A method of, and apparatus for, separating phases in a polyphase system is described and particularly in separating oil from produced water by the contact of gas bubbles and oil droplets by a dispersed gas flotation technique. A polyphase system is divided into at least two portions. The pressure of one portion is reduced to form bubbles of a gas, and the two portions are then recombined whereby the bubbles in the mixture enhances flotation, and hence separation of the dispensed phase, e.g. oil, from the continuous phase, e.g. water. The invention has particular application in the oil industry and in other fields where efficient separation is required.

Filed: 1990-03-30
Granted: 1997-06-24
Abstract: A method and apparatus is disclosed for mixing or agitating fluids using vortex rings in which a tube of inside diameter d is inserted into the fluid with an open end in the fluid. Fluid is drawn into the tube, and a slug of fluid is propelled a distance L down and out of the tube to create a vortex ring at the exit of the tube for propagation through the fluid. The ratio of L/d is between 0.8 and 3.8. The propelling means preferably involves a pulser cylinder communicating with the tube and a piston positioned in the pulser cylinder for reciprocating motion towards and away from the fluid to be mixed or agitated, or a bellows serving a similar function. The propelling means provides a generally square wave pressure impulse to the fluid to eject it from the tube in the form of a vortex ring.

Granted: 2000-12-12
Abstract: Precision multilayer optical interference coating of substrates having complex topology using complementary shaped electrodes and plasma enhanced chemical vapor deposition within a chamber. The materials for the optical quality thin films are obtained from starting reactants of the form M-R where M denotes a metal atom and R denotes an organic component. These vapor phase starting reactants are brought into a reactive atmosphere of the chamber through a plurality of orifices in one of the shaped electrodes. The resulting substances are deposited as thin films upon the substrates with inherently superior scatter loss performance because of the low temperature nature and simple direct vapor-to-solid phase transformation pith of the process.

Abstract: Dynamoelectric machines are disclosed that are characterized by lengthened ground potential leakage current paths, desirable mechanical conformations, mechanical integrity when subjected to expected centrifugal forces, and ease of manufacture. One process involves establishing an extended or elongated path for commutator leakage currents with a path extending structure, establishing a cantilevered insulation skirt about the in-board or armature coil end of a conumutator, and securely fastening such skirt to the commutator. The material utilized in making the skirt is one: that has electrical properties that permit it to withstand leakage currents without tracking; that for practical purposes is non-burnable, so as to resist flashovers or sparking; and that has the ability to withstand elevated temperatures that are encountered within dynamoelectric machine. The skirt is provided with openings therein and sandwiched between two glass based bands that adhere to another through the openings and thus lock the skirt in place on the commutator body.
