Abstract: ABSTRACT OF THE DISCLOSURE              An improved method of building a wooden door frame in a door opening of a building without shiming, and a precut and pre-assembled combination of wooden lintel and side post miter end assemblies, each comprising a jamb member with permanently installed outwardly extending mouldings, and if necessary a longitudinally extending doorstop on the main outer surface of the jamb member.  The miter ends of the assemblies are precut at 45 degrees at the point of manufacture when all their wooden components have been permanently assembled together, each assembly has a longitudinally extending wide shallow groove for miter L-shaped clips whose horizontally disposed arms are secured to the lintel assembly prior to erection.  The free arms of the L-shaped clips extend downwardly away from the lintel mouldings but as close as possible from the ends of the lintel assembly whereby, once the lintel assembly has been horizontally secured in place to the horizontal stud of a partition to be framed, the vertical arms of the L-shaped clips are received in the groove of the jamb member of each side post assembly to guide same so as to provide a perfect miter with minimum effort and time on the part of the carpen-ter.  A cross-piece adjacent the miter end of each jamb member prevents warping thereof and defines, with the shallow groove that it bridges, a deep slot for receiving the free arm of the corresponding L-shaped clip.

Abstract: ABSTRACT OF THE DISCLOSURE      Molten slag fresh from a smelting or refining furnace is ladled into a pan on a wheeled carriage and is thereby transported to a first heat recovery station, where water is heated by radiation from the slag while the latter is being agitated and granulated.          On granulation the slag is conveyed as by a skip hoist to a second heat recovery station, where the residual heat of the slag is utilized to heat air by convection.          The heated air is directed into a utility device such as a boiler, from which the cooled air is fed back to the second heat recovery station for reheating.  Several embodiments are disclosed.

Title: Self-centering feed apparatus for an abrasive  grinding machine
Inventor: GERBER DENNIS J
IPC: B24B7/12
Filed: 1981-01-23
Granted: 1983-12-06
Abstract: Abstract The disclosure is directed to a self-centering feed apparatus  (23)  for  a dual  head abrasive grinding machine (11).  The grinding heads (17, 18) are mounted in opposed vertical relation,  and workpieces are fed there-between along a horizontal  center  line  or plane.  The self-centering feed apparatus (23) comprises at least two sets (41, 43) of control arm mechanisms (45) mounted above and below the center line.  The control arm mechanisms (45) of each set are mounted in side-by-side relation on a common pivot shaft (47, 50), and are independently movable toward and away from the center line as the workpieces move through.  Each mechanism (45) includes a drive wheel (75) for engaging the workpiece and driving it through the machine.  Each control arm mechanism (45) is urged toward the center line by a spring loaded pneumatic actuator (77) that provides a constant gripping force,  and which also generates a resistive force that increases as a function of deflection of a control arm mechanism (45) from the center line.  This causes the workpieces to self-center on the center line and insures that they will be uniformly surfaced on both sides even in the presence of warpage or variations in thickness.

Abstract: FAIL-SAFE THERMOSTATICALLY CONTROLLED CIRCUIT      FOR USE IN APPARATUS FOR MELTING AND DISPENSING THERMOPLASTIC MATERIAL            Abstract of the Disclosure A fail-safe thermostatically controlled circuit is disclosed for use in high-throughput thermoplastic material melting and dispensing apparatus including a hopper into which solid thermoplastic material is deposited for feeding the thermoplastic material to a grid melter which melts the thermoplastic material whereupon the molten thermoplastic material flows from the grid melter to a reservoir from which the molten thermoplastic material is pumped to an applicator or dispenser.  Both the grid melter and the reservoir are preferably heated by electrical resistance heaters energizing by separate fail-safe thermostatically controlled circuits.  Each fail-safe thermostatically controlled circuit includes a manually adjustable thermostat for sensing the temperature of the molten thermoplastic material in order to connect a high voltage and current power source through a fusible element included in fail-safe circuitry to the electrical resistance heaters for energizing the electrical resistance heaters when the temperature of the molten thermoplastic material is below a preselected thermostat temperature setting.  The fail-safe circuitry also includes a shut-off temperature detector for sensing the temperature of the molten thermoplastic material in order to energize a heat generating element for melting the fusible element if the temperature of the molten thermoplastic material reaches a predetermined shut-off temperature which is above the preselected thermostat temperature setting, thereby disconnecting the power source from the electrical resistance heaters.

Abstract: ABSTRACT An atrial-ventricular demand pacemaker having improved atrial pulse artifact rejection includes a blanking circuit connected in the signal path from the ventricular output terminal to the sensing amplifier to blank the signal during an atrial pulse.  A holding circuit including a low-pass filter and a switching element stores a prior signal value at the sensing amplifier input during the blanking interval, and delays return to normal operation until after the blanking circuit has returned to normal.  Artifact rejection is also improved by limiting atrial pulse output circuit recharge time and by limiting polarization current driven into the ventricular output circuitry by an atrial output pulse.

Abstract: ELECTRICAL CONNECTOR ASSEMBLY HAVING                     ENHANCED EMI SHIELDING                              ABSTRACT         The present invention relates generally to electrical connectors and, particularly, to electrical connectors having superior electromagnetic interference (EMI) shielding charac-teristics.  In recent years a need has developed, particularly in the aerospace industry and in military applications, for electrical connectors providing effective shielding against EMI.  Many connectors, especially those employing conventional bayonet-type coupling devices, have proven to be inadequate to meet these needs.  There is a need for a bayonet-type connector having a construction of shell and interface components which will provide enhanced EMI shielding, given the limited coupling forces available with bayonet-type coupling mechanisms.  The electrical connector of the present invention comprises an assembly having a separable pair of connector members, including respective electrically conductive shells, and means for coupling the connector members in mating engagement, the coupling means including means for resiliently urging the connector shells together and means for pro-viding a continuous electrically conductive seal between the connector shells.
