Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to sinker cam seg-ments used in circular knitting machines of the type used in the manufacture of deep pile fabric.  It is common to make the sinker cams in arcuate segments for convenience in installation, and particularly for economy in the replace-ment of parts which experience the greatest wear in use.          The individual segments are attached to the cam ring by pins and screws.  The problem in the prior art to which the present invention addresses itself is that of sinker wear.  In accordance with the present invention, the seg-ments of the cam are beveled at their ends, in such a way that the sinkers, which lie in planes passing through the center line of the cam ring  will not encounter axial lines of intersection in the axially extending surfaces which they engage, nor radial lines of intersection in the radial surfaces which they engage.  This is accomplished by forming the ends of the cam segments at a compound angle, so that the end surfaces are in a plane having no elements which are either radial or axial, with reference to the center line of the cam ring.  A further aspect of the inven-tion consists of arranging the beveled end in such a way that the inside corner of a sinker at the butt passes over obtuse angles on the cam, on both running surfaces, as it arrives at the segment.

Abstract: ABSTRACT An electrical power controlling/load shedding system includes power consumption metering and meter interfacing circuitry for entering overall power consumption into a central processing unit.  The  CPU memory includes a data storage table characterizing each system electrical load under each of a hierarchy of operational levels, and circuitry is provided for turning local and remote loads on/off, responsive to CPU-issued commands. The digital computing apparatus operates on the meter supplied information and projects energy consumption over the monitoring interval.  If power must be shed to obviate an excessive projected demand, loads are examined seriatim and selectively shed on a priority basis as required, depending upon the operational parameters and status characterizing each load for the then pre-vailing load level condition.

Abstract: A water purification process is described for the removal of ammonia and optionally one or more acid gases from waste waters such as coke-plant or coal conversion waste waters. The process involves adding lime to these waste waters in amounts sufficient to react with fixed ammonia salts present in the waste water and to enable substantial amounts of the ammonia to be evolved upon distillation, adding a threshold amount of a scale inhibitor compound chosen from the class of certain organic phosphonates and subjecting the thus treated waste water to distillation to remove substantial amounts of the ammonia and acid gases present from the waste water.  Preferably, this process is achieved by two separate and successive distillations.  In this preferred process, the first distillation substantially reduces the amount of the acid gases and free ammonia and is con-ducted at a pH of more than 9.  In the second distillation, the amount of fixed ammonia is substantially reduced.  To conserve energy, the stripping vapors from the second distillation are reused as stripping vapors for the first distillation.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to incorporating a gas into a hot candy (sugar) melt within a pressure vessel at superatmos-pheric pressure.  The gasified hot melt is transferred from the pressure vessel to a cooling tube which hag a polished inner surface, through n line or lines connecting the bottom of the pressure vessel to the bottom of the tube, by creating pressure differential between the cooling tube and the pressure vessel while venting the top of the tube to the atmosphere.  When the transfer is complete, the cooling tube is isolated and the pressure within it is maintained at superatmospheric and it is cooled to a temperature below 70°F. whereby the gasified hot melt becomes a gas-containing solid matrix.  Next, the cooling tube is vented to atmospheric conditions.

Abstract: ABSTRACT OF THE DISCLOSURE   In a keyboard electronic musical instrument such as an electronic organ, an electro-mechanical memory device for holding in the down or actuated position one or more simultaneously depressed accompaniment chord and bass playing keys after the finger pressure from the instrument player is removed.  The signal representing the note or chord associated with the depressed key or keys is sustained as long as the keys remain latched down.  A plurality of keys of the lower or accompaniment manual are adapted to be retained in the depressed position and operate as part of the electro-mechani-cal memory device.  When a key or group of keys are latched down, the depression by the instrument player of another key releases the previously retained keys but the newly depressed key is latched down.  The electro-mechanical memory also operates in conjunction with the touch mode of the automatic rhythm unit to provide a rhythm signal when the accompaniment keys are retained in the depressed position.  The organ keyboard functions in the standard manner when the electro-mechanical memory is deactivated.
