Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed of manufacturing aluminum and aluminum alloy wire with reduced cross-section from wire of larger cross-section. The wire cross-section is first reduced down  to an intermediate cross-section by subjecting   the  wire  to  a  plurality  of  cold-rolling operations in a rolling-section with a plurality of stands using  water  as  a lubricant.  The  cross-section  is continuously  further  reduced  down  to  the  required cross-section by drawing  in a plurality of passes in a wire-drawing section, while applying oil to the wire as a lubricant.  The first reducing step in the wire-drawing section is performed by means of a roller die, the other steps  being  performed  by  means  of  normal  dies.  The lubricating oil circuit for the roller die is completely isolated from the lubricating oil circuits for the other dies. After wire-drawing the wire is coiled by means of a coiling-machine.

Abstract: ABSTRACT OF THE DISCLOSURE         A single phase alternating current two pole/six pole motor is provided with a main stator winding having six coils disposed unequally around the periphery of the machine.  These coils are divided into two groups.  When these groups are connected such that their magnetomotive forces  are  additive,  two  pole motor operation results. When the polarity of one of the groups is then reversed, six pole motor  operation  results.  An auxiliary stator winding which is similar to the main stator winding is displaced from the main stator winding by 90 electrical degrees on a two pole basis.

Abstract: ABSTRACT    Methods are disclosed which provide for quantifying and characterizing the mineral content of a formation as a function of depth.  Elemental data derived from logging tools are input into an element-mineral transform operation, preferably a matrix which is constructed using multivariate statistical analysis on previously available data, to determine the quantity of at least one or more dominant minerals in the formation.  From the mineral quantity information and the elemental log data, the formation minerals are further characterized.  Information regarding the character and quantities of formation minerals is further used to obtain improved determinations of formation characteristics such as the cation exchange capacity and water saturation, and the grain density and formation porosity, as well as to obtain an increased understanding of the formation such as the depositional environment of the formation.  A determination of formation characteristics and an increased understanding of the formation are both vital to production decisions concerning the formation.

Abstract: ABSTRACT OF THE DISCLOSURE         High-speed bipolar signals transmitted along standard twisted pair telephone wiring are subject to InterSymbol Interference which is corrected by an equalizer circuit that is operably responsive to predetermined parameters of bipolar signals detected at the secondary of a line transformer.  These parameters are input to a control logic circuit which includes several stages, each producing a set of past dependent logical control signals which are input to corresponding equalizer tap circuits having outputs connected to a common output bus.  Each tap circuit includes an integrator that is incrementally charged and under control an electronically switched capacitor.  A tap weight voltage output from each integrator is subsequently summed directly or inversely by a second switched capacitor under control of the logical input signals.  And, an equalizing signal output from the second capacitor is coupled through a buffer amplifier to the line transformer where it is added to the incoming signal and allows eye diagram monitoring directly at the transformer.

Abstract: ABSTRACT OF THE DISCLOSURE            Described herein is a method for-encapsulating components (1) on a carrier tape (2), particulary semiconductor compo-nents, with a polymer (15, 15') or similar material, which components are supported by their lead electrodes under a hole (20) on the carrier tape. According to the invention, a film material (8) coated with a cement layer is formed into a cup-shaped structure so that the cement layer is located on the inner side of the structure (9, 10). The bottom (10) of the cup-shaped structure (9, 10) is covered with a molding layer (15), preferably a polymer layer, and the cup-shaped struc-ture is placed in the hole so that its rims (9) extend over the edges of the hole and the component  (1) is brought into contact with the molding layer (15). In the next phase, the other side of the component (1) is covered with a protective layer (15'), preferably a polymer layer, which extends over the edges of the component (1), contacting the molding layer (15), and, furthermore, the cup-shaped structure (9, 10) is bonded at its rims to the carrier tape by pressing and heating. Finally, the molding layer (15) and the protective layer (15') are subjected to heat treatment so that they en-close the component (1) during a curing cycle. The cup-shaped structure (9, 10) prevents the protective polymer from spreading outside the desired area and gives the encap-sulation a clearly defined shape.          (Figure 13)

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a clamp for repairing a pipe. The clamp inclu-des a flexible metal band which is held about the pipe by a pair of lugs. One of the lugs is immovably connected to the end of the band and the other lug is adjustably connected so that the length of the band between the lugs may be varied so as to accommodate different outside diameter pipes. An elastomeric gasket sheet is attached to the metal band at its central por-tion and includes two free ends. The gasket sheet is long enough to encircle the pipe with one of its free ends overlapping the other. The overlapping free end includes a metal strip which underlies the lugs. The gasket sheet is pre-ferably wider than the metal band and has one edge which extends outwardly of the metal band. The outwardly extending edge is reduced in thickness and is adapted to cooperate with a channel formed in the edge of the gasket sheet of an adjacent pipe pre-pared clamp so that multiple clamps may be stacked lengthwise together .

Abstract: ABSTRACT OF THE DISCLOSURE      Herein  disclosed   is  a hydraulic  pressure regulating  arrangement  for  generating  a  servo actuating fluid pressure under which hydraulic fluid is  supplied  to  a  servo motor.  This  arrangement comprises a pressure regulating valve having a valve spool movable in response to hydraulic fluid pressure building up in a feedback chamber in such a direction as to increase opening degree of a drain port opening to  a  servo  actuating  fluid  supply  line  as  the pressure  in  the  feedback  chamber  increases.    A reservoir  is provided which communicates with the servo actuating fluid supply line.  A flow restrictor is  disposed  between  the  reservoir  and  the  servo actuating fluid  supply line and  restricts flow of hydraulic fluid entering the reservoir.  The feedback chamber communicates with the reservoir so that, upon start-up of  an  associated  oil  pump driven by  an engine, the valve spool stays in a position to close the drain port until hydraulic fluid discharged by the  pump  fills  the   reservoir,   thus  allowing unregulated servo actuating fluid pressure to build up in the servo actuating fluid supply line.
