Abstract: ABSTRACT      A workpiece to be treated, for example, an engine cylinder, is held vertically with a liquid-tight seal in a treatment device including a head which is fixed in the working  plane of a work bench, and a counter-head supported from the work bench by a bracket which can be raised hydraulically.  The device is selectively connectible, through control valves and circulation pumps, to reservoirs containing different treatment liquids.  The liquids enter the cylinder in an ascending flow through the head in such a way as to avoid swirling movements.  Preferably,several treatment devices are arranged to work in synchronism.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved valve seal assembly for rotary fluid control valves of the butterfly type which will seal tightly at high pressures, will not blow out under high system pressures, and which is operable with a relatively low torque.  A valve-closure disc is mounted for rotation between an open position, in which the disc lies substantially parallel to the axis of the fluid flow channel through the valve, and a closed position, in which the disc lies perpendicularly to that axis.  The disc is mounted for rotation on a valve stem which is attached to one side of the disc.  The disc cooperates with an annular, flexible seat circumscribing the fluid flow channel, for shutting off fluid flow through the channel when the disc is in the closed position.  The internal fluid pressure acting upon the valve is used to enhance the contact pressure between the flexible seat and both the valve body and valve disc, regardless of the direction in which fluid pressure is applied.

Abstract: METHOD FOR CONTROLLING SUBSURFACE BLOWOUT       ABSTRACT OF THE DISCLOSURE     A method of recompleting or controlling the flow of a formation which is inaccessible through the original wellbore and which is losing valuable hydrocarbons to another formation.  A second borehole is formed in close proximity to the first wellbore, and at least the bottom end of the new borehole is slanted until it penetrates the hydrocarbon bearing formation within shooting distance of the bottom end of the first wellbore.  A large casing gun is run downhole through the new borehole.  All of the shaped charges of the gun are oriented in the same direction.  Indexing means are included by which all of the shaped charges of the gun are oriented to fire towards the casing of the first wellbore.  After the gun is discharged, cement is pumped down the borehole, through the tunnels formed by the shaped charges, and into the perforations of the wellbore casing, thereby killing the flow of hydrocarbons from the damaged wellbore.  The two wells may be abandoned, or a whipstock can be employed to form a third lower end of still another borehole branched off the second borehole which penetrates the high pressure lower production forma-tion so that production can be established while salvaging the second one of the holes.

Abstract: ABSTRACT OF THE DISCLOSURE    A high speed closure sorter capable of producing an output of uniformly oriented closures from an input of a high speed flow of randomly oriented closures.  A capacitive proximity sensor discriminates between the orientation of each closure without contacting it.  An electric field is created between the sensor and the closures and in one orientation of the closures, a signal corresponding to that orientation is produced and in another orientation of the closures no signal is produced.  The produced signal is amplified to operate an ejector which allows closures having one orientation to pass directly to an output chute but ejects closures having another orientation into a second output chute.  One of the output chutes may return the closures to a hopper or may be curved to reorient the closures carried therein so that the outputs from both chutes are oriented in the same direction.

Abstract: Abstract of the Disclosure Phenolic foams and a method of producing phenolic foam material from phenol-formaldehyde resins having a phenol to formaldehyde mole ratio of between about 1:3 and 1:4.5 are described.  These materials are useful for insulation and other uses, particularly in the building trades.  They are dimensionally and thermally stable, fire resistant and low in cost.  Phenolic foams are generally obtained by cross-linking a suitable phenolic resin by means of a  catalyst in the presence of a blowing agent and a surfactant.  The high mole ratio resins disclosed herein are modified with formaldehyde co-reactants in order to form a useful foam.  Co-reactants for formaldehyde used according to the invention are urea, melamine and dicyandiamide, or combinations of these materials. The  most preferred co-reactant and the lowest cost material is urea.  Resins with phenol to formaldehyde mole ratios of from 1:3 to 1:4.5 according to the invention can be reacted with these co-reactants in relatively large quantities. The modified phenol-formaldehyde resins can be converted into a foam material which, surprisingly, exhibits pro-perties superior to those of foam based on a regular unmodified phenol-formaldehyde resin.

Abstract: ABSTRACT     In an integrated logic circuit having an inverter transistor with a signal input connected to its control electrode and one or more signal outputs each coupled via a diode to one of its main electrodes an interface or translation transistor is added. Preferably an ISL, clamped NPN transistor and a PNP interface transistor are merged together in a single semiconductive isolated island. The two transistors are laterally separated from each other along a semiconductive surface of the island, which also includes one or more metallic elements forming individual Schottky barrier contact diodes with the semiconductive surface. The PNP transistor provides translation between an ISL logic gate and a TTL lo-gic gate. One of the Schottky diodes may be used in combination with the NPN transistor as an active pull down for an output transistor of the TTL logic gate.
