Abstract: Refrigeration Unit with Water Cooled Condenser Abstract An engine-driven refrigeration unit includes a first heat exchanger functioning alternatively as a refrigerant condenser or as a refrigerant evaporator.  When the heat exchanger is functioning as a refrigerant evaporator the heat transfer medium furnished thereto for providing a source of heat to vaporize the refrigerant is preheated by absorbing heat from a relatively warm fluid employed as the cooling medium for the engine driving the refrigeration unit.

Abstract: METHOD OF CRYOGENICALLY HARDENING AN INSERT IN AN ARTICLE, AND ARTICLE MADE THEREBY                       Abstract A method of cryogenically hardening and expanding an insert in an article is disclosed. Particularly, gray iron piston ring insert having an austenitic matrix is treated in a piston body by impinging a cryogenic medium thereon.  This changes the matrix microstructure of the insert to at least about 25 Vol.% martensite and desirably increases the hard-ness level thereof to at least about 95 on the Rockwell "B" scale in the desired regions thereof.  The volume of the insert is also expanded to be more securely received in the piston body.

Abstract: Abstract of the Disclosure A post-primary oil recovery process wherein subterranean oil bearing formation is treated by the sequential steps of injecting an optional fresh water preflush through an injection well into the formation to adjust connate water salinity, followed by injection of an aqueous alkaline slug, such as agueous sodium carbonate thickened with a water dispersible or water soluble polymeric viscosifier, followed by injection of n thickened aqueous mobility buffer, and finally followed by the injection of an aqueous drive liquid with subsequent recovery of oil driven from the formation thereby. The thickened aqueous alkaline slug contains sufficient alkaline compound to satisfy 100 percent of the adsorption sites in the formation and all other consumption factors and to maintain interfacial tension between oil and water at a predetermined low level in the formation.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates generally to a glass fiber forming unit and more particularly, to a novel device which manu-factures glass fibers by using centrifugal force.  The device comprises a hollow spinner which has a bottom, surrounding wall in which are a number of molten glass projecting orifices and an upper annular flange.  An attenuating blast furnance is provided which attenuates the formed primary filaments into secondary filaments.  The invention is characterized  in that only an outer cone of the flame from the jet flame orifices of the blast furnace contacts the lower portion of the outer surface of the wall of the spinner.  A heating burner is provided inside the flange which jets a flame in the direction of the prolong-ation of the flange and parallel to its surface.  The flame from the burner heats the spinner as it goes along at least the upper surface of the flange and the heat is transmitted to at least a corner where the flange and the wall meet.  This device, when compared to the prior art, is relatively simple in con-struction, and provides glass wool fibers of good quality while using only a small amount of fuel thereby conserving energy.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to sheet transfer cylinders (2) on sheet-fed rotary printing machines with a device (15) for the register correction of overprints by deformation of the leading sheet edge (8) by means of flexure of the gripper fly shaft (10).            The problem of wider or narrower printing due to slight dimensional changes is solved in a simple way, as shown in Figure 1, by utilizing the swinging movement of sheet transfer cylinders (2) with pivoted gripper fly (6), to deform the leading sheet edge (8) in the centre, in or against the cylinder running direction.  For this purpose, the centre gripper fly shaft bearing (11) is mounted in a pivoted bearing about a point of rotation (12) parallel to the cylinder axis (14).  During the rotational move-ment of the gripper fly shaft (10), a cam (16) which is in a fixed mounting on the shaft runs against a roller (17) mounted on a support (13) of the cylinder axis (14).   restoring spring (19), which engages the centre gripper fly shaft bearing (11), ensures that the cam (16) is always in contact with the roller (17).  Depending on the design and the initial position of the cam (16), flexure of the gripper fly shaft (10), by means of spring resilience, is possible in or against the cylinder running direction, and the degree of flexure is adjustable.
