Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed of making sintered parts with cryogenically-produced powder derived from scrap metal, such as machine turnings.  The scrap metal is subjected to two impacting operations (such as by use of a ball milling machine).  The first operation is carried out with the use of a refrigerating agent (to lower the temperature of the scrap metal below its ductile-brittle transition temperature) thereby resulting in comminution of the scrap to a cryogenic powder; The second impacting operation is carried out at ambient temperature conditions utilizing milling elements which impart cold work to at least a portion of the cryogenic powder; simultaneously, copper is mechanically transferred to sub-stantially each particle of said cryogenic powder to form a continuous copper envelope thereabout.  The coated cryogenic powder is then compacted and sintered; the sintered product may be subjected to hardening or tempering treatments if desired.

Abstract: An automatic control for reducing a flow pressure compensated variable displacement pump to a standby condition while the pump operated motor is lowering a heavy static load.  The pressure in the motor exhaust line caused by the static load actuates the control to cut-off pressure to the downstream sensing line of the pump flow control.  A bleed orifice in that downstream sensing line depressurizes the line causing the pump displacement servo to stroke back the displacement of the pump to a standby condition.

Abstract: ABSTRACT OF THE DISCLOSURE An endless power transmission belt and method of making same is provided herein.  The belt is made primarily of an elastomeric material.          The belt is a flexible, cool running, stress-relieved belt, and these characteristics are imparted to the belt by cooperating components thereof including a continuous fabric layer which defines the inside surface of the belt and the fabric layer has a plurality of folded portions extending into the compression section of such belt at spaced positions along the endless path of the belt.  Each of the folded portions has associated portions of fabric in contact at an associated interface.  The interfaces serve as stress-relief slits for the belt with the associated portions of fabric serving as fabric cushions on opposite sides of an associated stress-relief slit.  The method includes the following steps: lining a member having a plurality of alternating ridges and grooves with a fabric material; placing a plurality of alternating ridges and grooves with a fabric material; plac-ing a plurality of elongated strips of elastomeric material in those fabric-lined grooves; laying a sheet of elastomeric material over such strips, to define an assembly; removing that assembly from the member and wrapping the assembly around a cylindrical drum to cause the fabric material to have a plurality of folded portions each having associated portions of fabric material arranged closely adjacent to each other; building the remainder of a belt-defining sleeve outwardly of the assembly; curing and cooling said sleeve, therebyto   the strips and sheet of the assembly to flow together as a unitary mass to define a compression section of the belts to be cut from said sleeve, and so that the associated portions of fabric material are folded against each other; and finally cutting said sleeve, to define a plurality of such endless power transmission belts.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to the provision of contours in deep-pile fabrics and especially to simulating contours found in natural furs and the like.  The various means proposed in the prior art for controlling the shape of the fabric back have proven to be unsatisfactory.  They have all caused some portions of the fabric to be stressed and strained excessively while other portions have been left uncontrollably loose.  These conditions have caused contour shapes to be very irregular in the finished pile.          The present invention overcomes these and other problems by providing a contour shear rest having a contour surface made up of elements forming a complement of a desired contour.          The contour surface is formed so that the length of the travel path of fabric drawn across its face is uniform.       Tension applied to fabric drawn across the various surfaces is therefore uniform and fabric distortion is substantially eliminated.  Consequently, as the fabric is sheared, it is provided with desired natural-looking contours.

The proportion of triazole used can range from 0.1 to 1.0 equivalent per equivalent of isocyanate in the prepolymer, and must be suf-ficient to increase that pot life of a mixture of the prepolymer with a diamine, but insufficient to cause substantial impairment of the physical properties of the cured elastomer.  A substantially equivalent amount of a diamine is then mixed with the stabilized prepolymer, and the resulting composition is heated to produce the elastomer.

Abstract: ABSTRACT      A device for displaying data in the manner of a page, for example, on a television monitor.  The device comprises a foreground memory and a background memory.  The foreground memory has a capacity of one page of text.  The background memory comprises serial sub-memories.  A number of these sub-memories is con-nected in  parallel; each sub-memory then contains part of a character (word), so that together they contain the relevant character within a series of characters. The characters become serially available on the out-puts of the relevant sub-memories for transfer, if necessary, to the foreground memory.  Said number of sub-memories can accommodate, for example, eight pages of text.  The sub-memories may be constructed according to the magnetic bubble technique.  Given data which cir-culate with the other data serve as a starting indication. The other pages can be addressed by means of difference data which indicate the distance in the series with respect to the starting data.  Further, fixed data con-cerning the length of a page enable a page of text to be readily presented, after appearance on an output of the background memory, to the foreground memory.  Each of said sub-memories preferably comprises a single loop so that intermediate control during the transfer of a page of data is very simple.  The foreground memory is preferably organized as a random access memory.  This memory can be addressed on the one hand in that the posi-tion of an address counter is each time increased by one unit.  On the other hand, this memory can be addressed in that the line address and the character address on the display apparatus are supplied to an adding device in order to form an address in an adding fashion.  The output of the memory has connected to it a counter which comprises sub-counting cycles having a length of one line on the display apparatus in order to form the lines to be displayed thereon.
