Abstract: The efficiency of an oil recovery process of the type wherein an aqueous surfactant solution is injected into a subterranean, petroleum-containing formation is increased by determining the optimum range of salinity and hardness e.g. calcium and magnesium, for the particular surfactant being used, and formulating an aqueous preflush solution, the salinity and hardness of which are within the range for optimum surfactant effectiveness, and adding an effective amount of hydrophilic polymer to yield a suitable viscosity greater than the formation water viscosity, and injecting the aqueous preflush solution into the formation prior to injection of the surfactant solution. The viscous, controlled salinity and hardness solution displaces the formation water effectively, thereby insuring that the salinity and hardness of the surfactant solution will be at or near an optimum value for oil recovery.

Abstract: A precision finishing machine characterized by orbital movement of bulk finishing media comprising supporting structure; a centrally disposed receptacle resiliently mounted on the supporting structure; a plurality of shaft-supported eccentrics mounted on opposing sides of said centrally disposed receptacle at substantially the level of the center of mass of the receptacle and its load, the longitudinal axes of said shaft-supported eccentrics paralleling one of the horizontal axes of the receptacle; flexible couplings connected to the eccentrics; and, connected to the couplings, a drive system including power means and auxiliary means for positioning, adjusting the position of, and controlling the power means.

Abstract: Relative axial movement of telescopically mounted support members is converted to rotation of an inertia mass by means of a ball-screw arrangement and a capstan spring loosely surrounding a portion of one of the support members. Slow acceleration of the inertia mass is accommodated, but rapid acceleration causes the inertia mass to lag which winds the capstan spring enough to grip one of the support members, which are rotationally fixed, and thereby snub movement until acceleration forces decrease. A spring band clutch positioned within the inertia mass and linked to the capstan spring ends enables the mass to slip in the event high velocity movement of the support members occurs and is then interrupted.

Abstract: A display fixture is disclosed which has a rectangular metal front frame, a pair of side walls, a brace interconnecting the side walls at the rear, and a series of drawers fitted into the front frame. The drawers are supported solely from roller brackets attached to the front frame in such a manner that the drawers are cantilevered from the brackets in both the open and closed position of the drawers. The drawers each comprise a rectangular frame of extruded elements into which are fitted bottom, side, front and rear wall boards.

Abstract: A thin, board-to-board zero force insertion and withdrawal connector having a housing containing a plurality of contacts with a first end portion of the contacts secured therein. A pair of parallel rows of rib-like elements extend along the length of the housing and define a U-shaped slot into which the edge of a circuit board can be inserted. The ribs form grooves therebetween which are perpendicular to the rows of ribs. The other end portion of each of said contacts extends downwardly into a groove towards the inner sides of said rib-like elements defining a side of said U-shaped slot, and then further extends upwardly towards the outer side of said rib-like elements. A plate is positioned along the length of said housing and secured thereto by a flexible hinge which divides the plate longitudinally along its length into two sections. A first of these sections extends over the said other end portions of said contacts. The other section of said plate has inclined planes formed on the inner surfaces thereof.

Abstract: Polyurethane urea elastomers with novel dissolution behavior and which are synthesized from polycarbonate macrodiols, diisocyanates and diamines and which can be prepared and dissolved in aqueous solvents.These elastomers have the advantage of being less of a physiological hazard, more resistant to common solvents and require less emulsifiers and dispersion aid.

These compounds have antimicrobial activity.

Abstract: A protective helmet assembly includes a flexible inner helmet designed to fit relatively closely over a wearer's head and fitted with one or more impact-absorbing pads, and a hard rigid ballistic outer shell comprising a frontal portion releasably secured over the forehead area of the inner helmet and a rear portion releasably secured over the crown-to-nape area of the inner helmet, and in which assembly the inner helmet is provided with a pad of relatively flexible ballistic material in the forehead region thereof below the frontal portion of the outer shell.

Abstract: A flip-up attachment for securing a windshield or other protective device to a helmet including a first element which is removably secured to the helmet in a sealed relationship therewith and a second element which is pivotally attached to the first element and includes as an integral part thereof means whereby commercially available face shields may be removably secured thereto without modification of either the attachment or the face shield. The two elements of the flip-up attachment are so arranged and configured that when the windshield is in the down or face protecting position a seal is formed between the two elements. The attachment between the two elements of the flip-up device includes a means whereby the relative friction may be adjusted, thus assuring that the windshield will be retained in its upward or in a semi-upward position when so desired. The two elements are latched together when in the downward position thus preventing the inadvertent relative movement during usage.

Abstract: Apparatus comprising a die head, a carriage provided with the die head and a pair of support rods mounted on a frame in parallel thereto and supporting the carriage movably in opposing relation to the pipe to be threaded. An elongated cavity parallel to the frame is formed in the carriage at a position immediately below the front end of an arm for advancing and retracting chasers on the die head. The support rod on the frame is disposed in the cavity, and a profile member fitted in the elongated cavity is movably supported by the support rod. The front end of the arm on the die head is placed on the top profile surface of the profile member, so that the threading torque of the die head causes the arm to fixedly press the profile member against the suppot rod and, at the same time, the lead of the chasers advances the carriage, while permitting the arm to move on the top surface of the profile member. Thus the open end of the pipe is formed with a tapered threaded portion having a predetermined length.

Abstract: An adjustable visored cap consisting of integral visor and forehead portions and an interchangeable crown portion provided with adjustable bands for adjustably securing the cap about the head of the wearer.
