Abstract: TORQUE BOOSTER CLUTCH WITH TIME DELAY           Abstract of the Disclosure An electromagnetic clutch having an armature drawn into engagement with an inner body upon energization of the clutch to establish a driving connection through the clutch, and having an arrangement to increase the engagement force between the armature and inner body to increase the torque capacity of the clutch.  The arrangement includes a plurality of balls cooperating with corresponding pockets which act to force the armature into tighter engagement with the inner body.  The disclosed clutch incorporates a time delay of the action of the torque boosting ball and pocket arrangement by forming at least one of the sets of pockets with elongated sections, allowing free movement without acting on the armature until after a pre-determined extent of relative rotation has occured.  A return torsion spring positions the balls And pockets in the proper initial position.

Abstract: ABSTRACT       Partially devitrified silica cores with exceptional high temperature strength are disclosed for foundry use in sand casting of ferrous alloys.  Precision cored holes of small size and long length, which heretofore could not be cast accurately or had to be machined because of limita-tions in existing core technology, are formed using accu-rately machined extruded porous silica cores fired to eliminate combustibles and partially devitrified (e.g., 15 to 30%) to develop a strong crystalline phase bond that resists viscous flow at a temperature of 1500°C. and to increase the refractoriness of the vitreous silica grains, whereby the permeability and thermal shock resistance are such that the core can be heated very rapidly by molten steel to above 1500°C. without spalling, cracking, sagging, breaking, or loss of integrity and without gas holes, scabs, fissures or other serious casting defects.       The cores are made from an extrudable composition containing vitreous silica, a mineralizer, an organic binder, and a plasticizer and/or tempering fluid.  High-purity vitreous silica grains are mixed with a mineralizer and large amounts of finer vitreous silica particles (e.g., below 10 microns) which bond the silica grains together to provide extremely high strength after firing. The extruded cores are fired to form cristobalite in major amounts in the bond region between grains and in minor amounts in surface portions of the silica grains.      The sand casting process of the invention can employ hollow porous thin-wall cores having small diameters, such as 0.4 to 2 centimeters or less, and length-to-diameter ratios, such as 20:1 or more.  The problem of casting defects due to gassing is solved by causing the expanding gases to move radially inwardly to the central passage of the hollow core.

Abstract: OSCILLATOR MODE SUPPRESSION APPARATUS HAVING BANDPASS EFFECT                         Abstract An apparatus utilizing the basic oscillation character-istics of the Colpitts or Pierce and Hartley oscillator con-figurations.  In this embodiment the basic shunt reactive shunt arms are replaced with a selected pair of tank circuits or one of the shunt arms with a series-parallel tank circuit.    These tank circuits are tuned such that the sign of their effective reactances are the same between the range of resonant frequencies of the individual tank circuits or of the series and parallel resonant frequencies of the series-parallel tank.          When this occurs and their sign differs from the sign of the effective reactance of the series reactive element, there is a 180° signal phase shift in the feedback loop, and therefore oscillation.

Abstract: LOW INFLATION WARNING DEVICE FOR PNEUMATIC TIRES          Abstract The low inflation warning device is a mechani-cal sound generating apparatus designated for attachment to a wheel assembly such that the apparatus is contained within the pneumatic space formed by the tire and rim.          Whenever a condition of low pressure or overload exists on the wheel assembly a warning signal is generated.  The signal is initiated by contact of the interior surface of the tire casing with the apparatus.  The contact causes a portion of the apparatus to strike an anvil with sufficient force to generate an audible sound.          The apparatus is self-setting under the influence of centrifugal force and will generate a warning of in-sufficient tire pressure or excessive tire load.  The apparatus will generate a signal with each revolution of the wheel assembly to which it is mounted.  Under extreme low inflation conditions the apparatus will continue to generate periodic warnings without damage to the tire.

Abstract: ABSTRACT OF THE DISCLOSURE       A power source circuit for a discharge type sensing circuit, comprising a blocking oscillator and a feedback circuit for changing the period of oscillation of the blocking oscillator is disclosed.  The sensing circuit as a load is connected to a secondary winding of a transformer of the blocking oscillator.  The base bias of a transistor of the blocking oscillator is controlled by the feedback circuit to which is applied a negative voltage produced in the primary winding in an off state of the transistor.  As a result, when the sensing circuit is in the sensing mode of operation, the period of oscillation becomes shorter for rapid supply of electric power and, when in the waiting mode of operation, the period of oscillation becomes longer for reducing supply of power, so that the power consumption is reduced as a whole.

Abstract: ABSTRACT         The inventor discloses a bidirectional communication system for electric power load management and distribution automation application, and the like, wherein outgoing control signals to a plurality of remotely located receivers and trans-mitters are sent using an existing standard AM broadcast station using small angle subaudible quadrature modulation.  The broad-cast signal is detected by narrowband synchronous receivers phase-locked to the carrier component of the broadcast station.          The radio frequencies of the plurality of reverse link trans-mitters are closely spaced and synthesized from frequency of said broadcast carrier and their time of transmission, digital bit streams, and message frames are all synchronized from the broadcast signal.  The broadcast station thereby orchestrates all communication activity to and from the plurality of remote locations to optimize traffic flow and miximize a priori information to all components to significantly increase reliability.  A unique fast Fourier transform processor sychronized by the broadcast station is employed in the central receiver to detect back link transmission.
