Abstract: Abstract of Disclosure Disclosed herein is a rotary internal combustion engine comprising a generally trochoid shaped housing including a pair of spaced generally parallel side walls, a generally triangularly shaped rotor supported within the housing for rotation about an axis perpendicular to the side walls, which rotor includes three generally identically shaped side flanks which define, in cooperation with the housing, respective chambers which rotate with the flanks and which vary in volume in accordance with such rotation. The side flanks each include an end which leads in relation to the direction of rotor rotation, an end which trails in relation to the direction of rotor rotation, and a length extending between the leading and trailing ends.  In addition, one of the side walls includes a charge inlet port which selectively communicates with the chambers in response to rotor rotation, which extends arcuately relative to the rotor axis, and which includes a portion which terminally communicates with the chambers and which is located such that the portion is closed off from communication with the chambers by respective parts of the flanks, which parts are spaced from the trailing ends in the direction toward the leading ends at a distance of from about 35 to 70 percent of the flank length.

Abstract: Abstract of the Disclosure Electrolytic copper of high purity is obtained by reduction electrolysis of copper sulphate solution obtained in the sulphuric leaching of conventional cupriferous materials and containing disturbing impurities. Prior to the electrolysis, the copper sulphate solution is subjected to a two-step leach purification.  In the first step the pH is maintained at 2.7 to 3.3 and the potential at least 575 mv in relation to a standard hydrogen electrode and compounds insoluble under these conditions are removed by solid-liquid separation.  In the second step, a reducing agent is added and the potential is decreased to precipitate copper (I) compounds which are subsequently removed by fine filtration.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of making a dynamically balanced V-grooved sheet metal pulley from a flat sheet metal disc by roller spinning and splitting tools.  The disc is provided with a central hole for mounting the disc on rotating die means between first head-stock and tailstock die form assemblies of a spinning machine. The spinning tool presses the disc against an end of a headstock die form and moves generally radially outwardly pressing a portion of the die against the end of the die to provide a circular hub wall.  The spinning tool then moves in a series of passes along the headstock die form thereby rolling, forming and ironing the rotating outer metal portions of the disc against the die and forming an axially extending cylindrical side wall terminating in a radially outwardly extending annular flange of a cup-shaped stage blank.  The flange then is trimmed to a predetermined length and to form a peripheral axially extending edge on the flange. The cup-shaped blank then is transferred to and clamped between second headstock and tailstock die form assemblies.  The clamped cup-shaped blank is rotated and splitting roll means splits the peripheral edge of the annular flange by exerting radial pressure thereon to form a rough V-shaped groove in the flange.  Finishing roll means then move radially into the rough V-shaped groove and forms a finished V-shaped pulley groove. Alternately, the spinning tool may thin the metal in the cylindrical side wall during the form-ing of the cup-shaped stage blank, whereby the finished pulley has a thicker reinforced circular end wall for receiving a hub than the thinned cylindrical side wall.

Abstract: ABSTRACT OF THE DISCLOSURE An improved process is provided for imparting hydrophobic preper-ties to building materials by applying solutions of a solvent containing or-ganosilicon compounds in an amount of from 0.2 to 25 percent by weight based on the weight of the organosilicon compound to the surface of building mater-ials.  The improvement comprises adding to the solutions of organosilicon com-pounds a small amount e.g. from 0.01 to 0.5 percent by weight of fillers hav-ing a surface area of at least 50 m2/gm.  The desired properties are achieved more quickly, and a higher degree of water repellency is achieved.  Moreover, the process does not require that loose filler residue be removed.

Abstract: PC-   CAN     Abstract of the Disclosure The invention relates to an improved silver/ silver-chloride reference electrode adapted for use in aqueous corrodent solutions at high temperatures and high pressures.  The reference electrode provides a useful standard for measuring electrochemical phenomenon related to the corrosion process so that metals can be compared on a thermodynamically useful scale.  The formation of bubbles within the reference electrode, which could cause open circuit conditions, is substantially avoided by equaliza-tion of internal and external pressure through the use of a vent means within the electrode body.  Ionic conduction between the electrolyte contained within the reference electrode and the corrodent solution is controlled by a bridge containing tightly gripped fibers.

Abstract: BLOOD OXYGENATOR                 ABSTRACT OF THE DISCLOSURE     A blood oxygenator wherein blood and oxygen are admixed by flowing blood, into which has been introduced bubbles of oxygen, through a three dimensional, open cellular mixing material having a substantial void volume.  In one embodiment, the admixing chamber is provided by an upright cylinder having an open interior.  In a second embodiment, the chamber has an annular interior configura-tion.  In both embodiments, the open cellular mixing material completely fills the cross-sectional interior of the chamber.  The resulting arterialized blood and blood foam rise to the top of the admixing chamber and are contained in a channel located at the top of the chamber and directed through this channel to the input of a defoamer chamber.  A defoamer filter of annular configuration is retained within the defoamer chamber such that the defoamer inlet is located at the top of the defoamer filter within the interior annular space thereof.  The blood foam thus enters the interior of the defoamer filter and is distributed over a substantial portion of the defoamer surface and collapsed therein to remove all en-trapped gases.  The oxygenated defoamed blood collects at the bottom of the defoamer chamber for return to the patient's body.

A loose flange is threaded on to each of the opposite ends of said pipe lengths or fittings behind the fixed sealing flange, such loose flange having a greater diameter than the sealing flange. The flange joint is tightened by means of bolts and nuts received in a number of holes through the part of said loose flanges located bey-ond the circumference of the fixed sealing flanges, causing the loose flanges to engage said annular concentric contact surfaces of the sealing flanges. The outer one of said con-tact surfaces is to be slightly depressed in relation to the inner one.

Abstract: ARRANGEMENT FOR CONTROLLING   SEIZURE OF A CONNECTOR      Abstract of the Disclosure A prior art crossbar switching system provides a test frame connector which may be seized by a marker for the purpose of causing a trouble data record to be made (e.g., by a trouble recorder card perforator).  All markers compete for normal seizure of the connector by means of the usual connector seizure circuit arrangement of preference relays and connector relays whereby normal marker seizure attempts are recognized and served so that only one normal seizure at a time is permitted.  A new interface circuit is provided so that a computer can effect a special seizure of an idle connector and so that no  normal seizure attempt can be recognized by the seizure circuit while the special seizure situation prevails; however, the interface can detect a normal seizure attempt which occurs at any time while the special seizure is in the process of being effected.  Upon detection of such a normal seizure attempt, the interface causes the cessation of the special seizure situation so that the normal seizure attempt can be recognized and served.  Thus, any such special seizure situation is rendered transparent to normal marker seizure attempts. Also, the interface permits the computer to intercept a normal marker seizure of the connector so that the computer can either collect the trouble data in lieu of the perforation of a trouble card or can allow the usual trouble card to be perforated.
