Granted: 1979-01-02
Abstract: ABSTRACT OF THE DISCLOSURE   A multi-chambered combuster apparatus for the controlled burning of all forms of light combustible organic material and the generation of steam or dry heat energy, resulting in essentially pollution free combustion as atmospheric emissions have zero opacity and low particulate discharge. A primary combustion chamber in which air and fuel are introduced in controlled ratio has interior walls acting as ignition surfaces which also direct combus-tants in a cyclonic flow path. Combustion gases then expand into a counter-flow chamber where cooling and deceleration causes settling of pollutants. The gas stream next enters a purification chamber, passing through a hot filtering medium which entraps any remaining fine particulate matter.

Abstract: ENERGY ABSORBING AND PRESSURE APPLYING ARRANGEMENT FOR ELECTRICAL CONTACTS                   ABSTRACT OF THE DISCLOSURE          An energy absorbing and contact pressure applying arrangement which minimizes bounce of a movable electrical contact upon engagement with a stationary or fixed electrical contact.  In an illustrated embodiment, an armature member is attracted by an electromagnet means to draw the movable contact into engagement with the fixed contact.  The movable contact engages the fixed contact before the armature has completed its travel into magnetically sealed engagement with the core of the electromagnet means.  During the additional increment of travel necessary for the armature to move into magnetically sealed relation to the core of the electromagnet means, means connected to the moving armature causes compression of an energy absorbing and contact pressure applying device against the carrier arm on which the movable contact is mounted.  The energy absorbing and contact pressure applying arrangement may be a composite spring comprising a helical metal wire coil spring embedded in a suit-able energy absorbing material such as an elastomeric material, preferably silicone rubber, which dampens the natural resiliency or tendency to bounce of the metal wire spring.  The resiliency of the metal wire spring itself is a significant factor in con-tact bounce.  The energy absorbing device greatly reduces, as compared to the prior art, the duration of the time interval during which the movable contact bounces relative to the fixed contact due to the impact of closure, to thereby greatly reduce the duration of arcing and in many instances substantially reducing the amplitude and amount of the arc current between the contacts during the bounce period, with consequent reduction in erosion of the contacts.  The reduced duration of the bounce period, in accordance with the present invention, also reduces mechanical wear on the contacts.  The advantages of the invention just described result in a substantial increase in contact life.          In a modified embodiment which operates upon the same principle as hereinbefore described, movement of the movable contact into engagement with the fixed contact and compression of the energy absorbing device against the movable contact are both imparted by a magnetic plunger which is axially movable in an electro-magnetic solenoid.

Abstract: ABSTRACT OF THE DISCLOSURE          A torque signaling attachment for a conventional torque wrench for producing a visual or audible signal when the wrench is applying a predetermined torque.   In a conven-tional torque wrench, the angular offset between the torque beam and the indicating pointer is proportional to the applied torque.  The signaling attachment detects a predetermined lateral offset between the beam and pointer.  The indicating device is secured to the torque beam, and the torque corres-ponding to the predetermined lateral offset is determined by the location of the signaling attachment on the beam.   When the beam becomes laterally offset from the pointer by the predetermined amount, the pointer contacts the signaling device to complete an electrical circuit and produce a torque indicating signal.  The signaling device is calibrated by applying a predetermined torque with the wrench and adjusting the position of the device along the torque beam until the signal occurs.

Abstract: ABSTRACT OF THE DISCLOSURE This device relates to the field of distributing devices for multi-conductor cables, and more particularly to distributing devices which allow modification of the circuits by the insertion of a plug.  Considering the high number of connections in a telephone switching center, there are several requirements of equipment to be used there.  Space is at a premium and must not be wasted due to a poor design of the distributing device.  The circuits must be accessible to effect a measurement or modification of the circuit. The existing devices used for this purpose occupy a considerable amount of space.  It is also necessary to be able to temporarily use portions of one cable for satisfying an excess demand on another cable.  With know devices, this operation is relatively complicated.  The present Invention provides a distributing device made up of a set of modular elements.  Each of the modular elements includes symetrically arranged pairs of conductors.  Each pair of conductors includes an incoming conductor to be connected to one wire of the multiconductor cable and an outgoing conductor to be connected to a jumper wire.  The two conductors are normally shorted together by a spring contact.  A plug is provided which by partial insertion allows con-nection to the conductors of a pair without interrupting the connection between the two conductors, and upon complete insertion pushes the spring contact away from the conductors to interrupt the connection between the two conductors.
