Patent CA-1106569-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         This invention concerns a method of manufacturing plastic bonded magnets and those magnets consist of a generic material, "Lanthanoid", plus yttrium.  "Lanthanoid" represents elements 57 to 71 inclusive in the periodic table of elements. The manufacture of those magnets comprises the steps of pulverising the "Lanthanoid" material and aligning the magnetic powder in a magnetic field.  The magnetically "Lanthanoid" material is first ground to a powder with a particle site of 1 - 100 µ, and when the powder is aligned in the magnetic field it is pressed under a pressure of p - 1000 - 10 000 kp/cm2.  The "green" body thus obtained is then subjected to heat treatment above the Curie temperature up to a maximum of 1150° in a protective atmosphere for 1 - 20 h, and the resulting body is then infiltrated with plastic in a vacuum of approx. 1 - 30 Toor at a temperature of approx. 20 - 80°C, and the body thus infil-trated is then pressed again in the plastic in liquid form with a pressure of 2 - 2000 kp/cm2.  After the plastic is cured the final magnet is machined and then it is magnetised under the influence of a magnetic field.

Abstract: ALL ANGLE BOREHOLE TOOL                     ABSTRACT OF THE DISCLOSURE          Inclination and high side angle of a borehole is measured by a tool that may be positioned inside a drill string and lowered into the borehole.  The tool includes three gravity transducers positioned in a novel array.  The transducers are positioned in a case whose axis coincides with that of the borehole and are arranged with their axes angularly displaced from each other around the case axis by approximately 120 degrees and from the case axis by approxi-mately 45 degrees.  An array of fluxgate magnetic transducers may be added to the apparatus to provide combination surveying and steering capability.

Abstract: ABSTRACT OF THE DISCLOSURE     In a method of treating a coil spring to improve its performance and reliability when operating at elevated temperatures, the spring is first stressed by applying a load of preselected magnitude and then, whilst the load is maintained, the spring is heated until it relaxes or collapses to a predetermined extent at which stage the heating is automatically discontinued and the applied load is afterwards removed.  Apparatus for carrying out the method in relation to compression springs includes a spring supporting base, an overhead operating head with a vertically movable ram or plunger for applying the predetermined load, means for passing an electric heating current through each spring whilst beneath the operating head, and limit switch means which responds to the position of the ram or plunger and terminates the supply of heating current when the loaded spring has reached the required predetermined value of relaxation or collapse.  The apparatus may also include means for carrying out a preliminary cold pressing of the springs before the hot pressing operation.

Abstract: MEANS FOR EFFECTIVELY CONTROLLING THE FORCES      IMPOSED ON THE MOVABLE CONTACT OF A      VACUUM-TYPE CIRCUIT INTERRUPTER     Abstract:   This vacuum-type circuit breaker has means for substantially reducing the tendency of the contacts to bounce apart in response to the impact between the contacts occurring at the end of a closing stroke.  The circuit breaker includes a contact-wipe mechanism comprising a driving part and a wipe spring located between the driving part and the movable contact which spring is loaded to produce added closing force on the movable contact by continuing closing motion of the driving part after the contacts initially enagae at the end of the closing stroke.  The wipe mechanism further includes a bounce-suppressing spring acting in opposition to the wipe spring and discharging to aid said continuing closing motion of said driving part during the initial stages of said continuing motion following initial contact-engagement.    The wipe mechanism also includes means for precisely controlling the forces imposed on the movable contact by acceleration at the start and termination of a contact-opening stroke.

Abstract: ABSTRACT OF THE DISCLOSURE             Disclosed are an integral plastic bowl, waterway and trap for a toilet and the method of making the product. The bowl is concave and leads into a trap which may be interconnected with a standard closet flange. The waterway is vertically aligned with the trap and slopes downwardly from an inlet to an outlet, which is preferably at a position near the bottom interior of the bowl and which also preferably includes a wall surface in overlying alignment with at least a portion of the downwardly sloping waterway portion. During flushing, water from a reservoir flows down the waterway, against the outlet wall surface causing a vortex in the bowl, and then out of the bowl into the trap. In the method of making the product, a plastic parison is positioned between the sections of a blow mold. Next, the mold sections are closed, pinching portions of the parison shut to partially form the trap and waterway and enclosing another parison portion in a bulbous mold cavity. Blow fluid under pressure is injected into the interior of the parison to form a blown article which is then removed from the mold and trimmed to form the final product.

Abstract: BELLOWS WITH ROTATIONAL JOINTS        Abstract of Disclosure A heat suppressor for a gas turbine engine is mounted on an aircraft by means separate from the engine mounts. A sleeve apparatus is needed to connect the exhaust duct of the engine to the suppressor duct for continuous flow of turbine gases. The sleeve apparatus is in the form of a bellows to absorb bending forces created by flexing of the air frame. This in-vention provides a unique connecting assembly to connect the bellows to the engine. The assembly consists of an annular socket fixed to the bellows and constructed to receive a radially extending flange on a connecting shroud fixed to the engine.      The flange and socket are slidably engaged to allow twisting movement between the bellows and the engine, while the bellows allows relative displacement of the axes of the connecting passages.

Abstract: ABSTRACT OF THE DISCLOSURE          An inner ring of an anti-friction bearing has a central bore with a groove that extends radially outward and circumferentially about an axially intermediate por-tion of the bore.  At a radially outermost portion of the groove is a bottom that is eccentric to the bore.          A shaft is received within the bore and maintained centric with the ring.  A longitudinally split locking sleeve having an eccentric external contour fits within the groove when the eccentric central axes of the groove bottom and the external sleeve contour are radially aligned with each other from the central axis of the bore.  The sleeve has an unstressed bore diameter that is less than the shaft diameter to inherently grip the shaft when inserted therein.  Relative rotation between the sleeve and the ring wedges the sleeve and inner ring into a locked posi-tion on the shaft.  In a preferred embodiment, the ring has a radial hole therein intersecting one radical end of the groove, and at a radial end of the sleeve is a notch for alignment with the hole.  Rotatably mounted within the ring hole is a pin that has a lug projecting eccentrically therefrom into the notch in the sleeve.  The pin and lug can maintain the alignment of the sleeve relative to the ring, while a shaft is being inserted into the sleeve, and then rotate the sleeve relative to the ring to lock the ring and the sleeve upon the shaft.     -1a-
