Abstract: A product for inhibiting corrosion of corrodible items within closed containers which comprises a powdered solid composition capable of producing and releasing a vapor phase corrosion inhibiting compound. The powdered composition is enclosed within a sealed envelope which is formed of a sheet material impermeable to the powdered composition, but which is porous to the released vapor phase corrosion inhibiting compound released from the powdered composition. The vapor phase corrosion inhibiting compound produced and released by the powdered composition migrates through the sheet material and permeates the environment of a closed container of corrodible items.

Abstract: An apparatus for heat sealing thermoplastic articles includes a heater movable reciprocably in a longitudinal direction, and two opposed transversely reciprocable and pivotable carriers, each supporting a thermoplastic workpiece to be bonded. Two opposed heating surfaces of the platen heater are inclined and diverge in the longitudinal direction, to give the heater a "V" configuration. The carriers may be pivoted to a corresponding "V" configuration to position each workpiece against an associated heating surface of the platen. Following heating of the workpieces, pneumatic or other force applying cylinders urge the carriers toward one another as the heater is withdrawn from between them. Cam surfaces on the heater cooperate with cam following rollers on the carriers to control the position of the carriers during withdrawal of the heater, and permit rapid and accurate engagement of the thermoplastic articles after withdrawal.

Abstract: A surgical cutting blade for use in an electrosurgical scalpel includes a thin flat ceramic substrate having a rounded tip where the edge portion of the substrate on the opposed major surfaces thereof are beveled. A pattern of metallization is provided on the opposed major surfaces of the blade substrate with the metallization extending over the tapered portions. The substrate is then back-ground to form a blunt edge extending between the tapered surfaces at the edge of the substrate. The metallization pattern further includes traces extending from the conductors along the blunt working edge of the blade to the handle receiving portion thereof and provide a means whereby RF energy may be conducted to the metallized working edge of the blade.

Abstract: A system and circuit for selectively presenting to a display terminal information obtained from a video camera and from a computer terminal so that computer generated graphics information can be superimposed with the camera picture on the face of a display screen. An interface adapter circuit is coupled to the computer's address and data buses and is used to drive a video mixing switch to provide a computer monitor with either computer generated graphics or video information originating at a video camera, with synchronization for the camera provided by the computer terminal.

Abstract: A process for removal and recovery of chromium ions (chromate, dichromate, or combinations thereof) from aqueous waste water of surface treatment phosphatizing solutions and for recycling of the treated waste water following replenishment wherein the aqueous waste water is initially partially clarified in a settling tank, with the effluent then being passed through an ion exchange column for removal of substantially all of the chromium ions therefrom. Following treatment in the ion exchange resin column, the chromium-free material is recharged with a supply of fresh chromium ions until the chrome ion content is at the desired level for metal surface treatment. The spent ion exchange resin columns are removed and replaced, as necessary, with the recharge of the resin columns making additional chromium available as a resource.

Abstract: An adhesive strip-like bandage for application to skin wounds for sealing the wound without surface stitches or staples. The wound closure strips may be fabricated from a bias cut, woven, or non-woven, polymer-based material or other film, exhibiting uni-directional stretch properties which permits the strips to stretch in a controlled manner during wound healing. The strip bandages are detachably mounted to a backing member and in one configuration comprise a comb-like structure.

Abstract: A network communications adapter interconnects a plurality of digital computing resources for mutual data exchange in which a high performance, large capacity common memory is provided with a pair of external buses which allows multiple processors to store information in and read information from the common memory. The common memory is configured into two banks, each bank operating independently and concurrently under control of bus switching logic with separate address, control and data buses. The common memory typically provides 400 megabits per second of bandwidth to the multiple attached thirty-two and sixteen bit processors which may be coupled either to both buses simultaneously or individually to the two buses. The bus switching logic then allocates all of the available bandwidth to the individual processors coupled to the buses based upon a predetermined profile established at the time of system installation. Also included in the bus switch logic is circuitry for broadcasting a processor I.D.

Abstract: A method of graphically displaying cardiopulmonary function data by providing a plurality of axes radially projecting from a common point of origin, there being one such axis for each cardiopulmonary parameter to be plotted, each axis having scale markings thereon whereby the normal value for each parameter will lie an equal distance from said point of origin, and straight line segments connected between said normal values on adjacent axes will form a generally regular polygon. The cardiopulmonary function data to be displayed are then plotted on the same appropriate axis and to the same scale such that deviations of any such data from normal will result in an irregular polygon when the segments are joined between plotted values on adjacent axis. Deviations of the irregular polygon from the regular polygon thus provides a clinician with a readily visible display of possible cardiopulmonary disfunction.

Abstract: A system for detecting and isolating fault conditions occurring within a digital electronic system. The digital electronic system includes a first digital logic array for generating digital outputs in response to a set of digital signal inputs applied to it. The digital logic array is replicated and the second array is configured to receive the same inputs as the first. The first and second arrays are made to operate in synchrony so as to normally produce identical outputs in the absence of fault conditions occurring either in the first or second array or in the inputs applied to them. The digital outputs from the first array are applied to first and second residue code generators having different modulii. Likewise, the outputs from the second arry are applied to third and fourth residue code generators which are identical in make-up to the first and second residue code generators.

Abstract: A spacer is provided for locating a reinforcing cage or fabric, with respect to a form, when manufacturing reinforced concrete articles such as piping, manhole sections, walls and the like. The spacer is formed from a single length of heavy gauge steel wire, and includes a mounting section which wraps around a longitudinal rod of the reinforcing framework and abuts a transverse rod at its junction with the longitudinal rod. An intermediate section of the spacer extends transversely from the mounting section and is approximately parallel to the transverse rod. A hook at the end of the intermediate section remote from the mounting section is positioned to latchingly engage the transverse rod responsive to elastic deformation of the spacer, thereby to securely maintain the spacer on the reinforcement framework. A spacing loop of a predetermined dimension is provided along the intermediate section.

Abstract: An anti-sway system for a steerable vehicle of the type employing a torsion bar suspension system. Operatively coupled to the torsion bar for each of the vehicle's steerable wheels or skis is a mechanism for increasing the effective spring rate of the suspension upon cornering over that prevailing when steering a straight line course.

Abstract: An adjustable neck is provided for adjusting a lamp, in particular a lamp plugged onto a low-voltage rail, in as many alternative directions as possible. The adjustable neck is mounted between a clamping socket of the lamp and the replaceable incandescent body or bulb. The adjustable neck includes several joint members, each consisting of a ball portion that can be plugged into a corresponding joint seat portion of a next adjacent joint member and held there by a friction fit. The incendescent body can be surrounded by a lamp shade provided with ventilating slots. The clamping socket is embodied such that a positive anchoring is achievable even in the case of larger, heavier lamps.

Abstract: A support and stabilizing apparatus for an electrical outlet box, such as a conventional electrical outlet box having a plurality of side walls and a back wall defining a chamber with an open front and having an access bore formed through at least one of the walls. The support and stabilizing apparatus comprises a stud apparatus having a shaft with forward and rearward opposed ends and generally cylindrical forward and rearward abutment plates secured to the shaft in predetermined spaced apart relationship.
