Patent CA-1044306-A (CA)

Abstract: Abstract of the Disclosure When a blade is used to clean a moving surface, the blade acts to clean substantially all the material from the surface while there is relative motion between the blade and surface above a given value, it has been found that liquids will pass between the blade and the surface at small or zero relative speeds.  This material will not be cleaned off by the blade after relative motion has resumed. This problem is obviated by intermittently moving the blade in one direction relative to the surface in engagement therewith with rest periods between periods of relative motion in the aforesaid one direction.  Then, before each such rest period, the relative motion between the blade and the surface is reversed with the blade still in engagement with the surface.

Abstract: ABSTRACT OF THE DISCLOSURE                A process for altering the residual stain remain-ing along the relatively sharp bend of a glass sheet resulting from the fusion of an electrically conducting glass frit suspension applied to the sheet along a path coincident with the line about which it is desired to sharply bend the sheet by passing electrical current therethrough to heat the glass adjacent thereto and effect the bend.  The process includes interposing a strip of coloring agent between the glass sheet surface and the electrically conducting path lenthwise of the latter prior to electrically charging the same to form a resultant stain along the sharp bend of desired appearance.                                                    ,

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an imaging method useful in facsimile transmission.  The method involves passing an electrical current through a receiving member of a solid state persistent electro-chromic material uniformly distributed on the surface of a substrate having a resistance greater than the electrochromic material.  Treating the substrate to lower its resistance to a level less than or equal to the electrochromic material, passing a current through the receiving member in imagewise configuration and returning the substrate to its original state of resistance provides a persistent image in the electrochromic material.

Abstract: Abstract of the Disclosure:  An improved hydrostatic trans-mission control system includes a main control valve which varies the speed at which a vehicle is driven as a function of variations in throttle setting, engine output speed, and displacement of the hydrostatic transmission.  Upon actuation of a brake pedal, a linkage effects a deswashing of a pump unit in the hydrostatic transmission to reduce the speed at which the vehicle is driven.  Continued actuation of the brake pedal causes the linkage to effect engagement of the vehicle brakes.

Abstract: ABSTRACT OF THE DISCLOSURE         An electrical device for protecting an alter-nating current network in which a static inverse time-overcurrent relay obtains network current information and relay circuit operating power from a current transformer having two secondary windings.  Low transformer burden and accurate network information signals that are linearly responsive to a wide range of network current magnitudes are achieved through the use of a switching circuit that prevents the simultaneous operation of both secondary windings The relay circuit employs an RC network with a short, pre-cision time constant for curve shaping and employs digital counting techniques to provide time delay multiplication, precision time scale selection and a variable delay time variable in accordance with the magnitude of system current.

Abstract: ABSTRACT   Disclosed herein is size reduction apparatus such as a granulating machine of the type for cutting plastics and the like.  The granulating machine includes a chamber provided with a driven rotor having a series of cutting knives affixed on the periphery thereof.  The cutting knives cooperate with stationary bed knives to comminute material fed into the cutting chamber.  One or more screens are positioned in the bottom of the chamber and allow for the discharge of the material after it has been reduced to a predetermined size.  A series of fluid nozzles are arranged to deliver fluid such as air under pressure into the chamber in the zone below the axis of rotation of the rotor.  The air acts to effect a scrubbing of the granulator screen, improve cooling of the cutting chamber and cool the cutting knives.  By such scrubbing and cooling in the area of the discharge screen heavy build up of material on top of the screen is precluded as the material is circulated and suspended.  Also, melting of the terhmoplastic material in the chamber is prevented.

Abstract: Abstract of the Disclosure The disclosed magnetic devices, including a magnetically coupled conducting path, incorporate amorphous, low magnetostriction alloys of the general formula (CoaFebTc)iXj, the "metallic" constituents thereof being within the parenthetical expression.  T, in the formulation, is selected from among Ni, Cr, Mn, V, Ti, Mo, W, Nb, Zr, Pd, Pt, Cu, Ag and Au, X being at least one "glass former" selected from among P, Si, B, C, As, Ce, Al, Ga, In, Sb, Bi and Sn.  The metallic constituents comprise from 70-90 atomic percent of the alloy with cobalt being present in an amount of at least 70 atomic percent of the "metallic" constituents.  The described material is prepared by rapid cooling from the liquid directly to the shape needed for fabrication of the device (e.g., tape to be wound to form an inductor core).  When the amorphous material is fabricated to its finished geometry, raised to a temperature somewhat below its crystallization temperature and quenched in a high heat of vaporization liquid (e.g., water), the permeability is greatly improved.  An exemplary alloy was shown to possess properties, in some respects, equivalent to those of Supermalloy (Trade Mark), an alloy of much more complex manufacture.
