Abstract: SOLID STATE IGNITION CONTROL Abstract: A control arrangement for a fuel ignition system having pilot and main valves in which the energization or the operate windings of the pilot and main valves, which are connected in series, is controlled by a silicon controlled rectifier. The SCR is enabled at the start of each ignition cycle by trigger pulses provided by a pulse generating cir-cuit and when enabled, the SCR provides a shunt circuit path around the main valve winding permitting the pilot valve winding to be energized at its operating level effecting pilot valve operation and preventing the main valve from operating. When a pilot flame is provided, a capacitor of a flame sensing network is charged by flame rectified current, generating an inhibit signal for the pulse generating circuit which causes the SCR to be cut off, interrupting the shunt path to allow the main valve winding to be energized, effecting main valve operation. A trial for ignition timer deactivates the pilot valve and locks out the system if the pilot fuel fails to be lit before the end of a trial for ignition inter-val, the ignition timer being rendered ineffective in response to disabling of the SCR when a pilot flame is sensed. In one embodiment, the ignition timer comprises a time delay relay which is resettable by cycling the thermostat contacts open and closed. In another embodiment, the ignition timer comprises a thermal cutout switch mounted on the pilot valve and heated by the pilot valve operate winding.

Abstract: Abstract of the Disclosure Capacitive electrical heating of a fluidized bed enables the individual solid particles within the bed to constitute the hottest portion thereof.  This effect is achieved by applying an A. C. voltage potential between di-electric coated electrodes, one of which is advantageously the wall  of the fluidized bed rejection zone, sufficient to create electrical currents in said particles so as to dissi-pate heat therein.  In the decomposition of silane or halo-silanes in a fluidized bed reaction zone, such heating en-hances the desired deposition of silicon product on the surface of the seed particles within the fluidized bed and minimizes undesired coating of silicon on the wall  of the reaction zone and the homogeneous formation of fine silicon powder within said zone.

Abstract: APPARATUS FOR STOPPING ARTICLES        ON A CONVEYOR             ABSTRACT OF THE DISCLOSURE           A continuously movable conveyor supports a plural-ity of articles for movement along a path leading to and beyond a zone at which selected articles are transferred from and returned to the conveyor.  At the transfer zone is stop apparatus movable from a position clear of the path of movement of the articles on the conveyor to a position in which it projects into such path of movement so as to en-gage and stop an oncoming article as the conveyor continues to move.  The stop apparatus includes a stop member supported by a parallelogram linkage which is rockable by an extensible and retractable hydraulic ram to effect movements of the stop member into and out of the path of conveyor borne articles.          The coupling of the ram to the stop member includes a lost motion connection enabling displacement of the stop member upon engagement of the latter by an article on the conveyor and the ram is yieldably retractable in response to such engagement so as to absorb and cushion the shock of such engagement.  Following stopping of the article on the con-veyor the ram returns to its extended position and locates the stop member in such position that, upon retraction of the ram to move the stop member out of the path of move-ment of conveyor borne articles, the stop member has a com-ponent of movement along the conveyor path so as to avoid the imposition of binding forces on the stop member by the article engaged thereby.

Abstract: WASTE HEAT RECOVERY SYSTEM HAVING THERMAL SLEEVE SUPPORT         FOR HEAT PIPE            ABSTRACT A system for recovering waste heat from a stream of heated gas is dis-closed. Tile system includes a convection heat transfer chamber, a boiler tank, and a plurality of heat pipes thermally interconnecting the convection heat transfer chamber with the boiler tank. Each of the heat pipes includes an evaporator section which is disposed in heat transfer relation with a stream of heated gas flowing through the con-vection heat transfer chamber, and a condenser section disposed in heat transfer relation with a volume of water contained within the boiler tank. The boiler tank is provided with a header plate having an array of heat pipe openings through which the heat pipes project. A heat pipe support sleeve is received in each heat pipe opening in sealed engagement with the header plate, with the heat pipes projecting through the support sleeves and thermally interconnecting the convection heat transfer chamber with the boiler tank. An intermediate portion of each heat pipe is received in sealed engagement with its associated support sleeve. In a preferred embodiment, heat transfer through the support sleeve is minimized in an arrangement in which each heat pipe opening is reduced by a stepped bore with the support sleeve connected in threaded, sealed engagement with the stepped bore. Furthermore, in this arrangement, the support sleeve has swaged end portions which project beyond the header plate and engage the heat pipe on opposite sides at points which are remote with respect to the support sleeve/header plate interface. One of the swaged end portions is sealed against the heat pipe in a fluid-tight union within the boiler tank. The support sleeve is radially spaced with respect to the heat pipe, and is also radially spaced with respect to the heat pipe opening whereby heat transfer through the walls of the heat pipe to the support sleeve and to the header plate is minimized by concentric annular air gaps.

Abstract: POWER SUPPLY FOR A HIGH INTENSITY   DISCHARGE OR FLUORESCENT LAMP                 ABSTRACT OF THE DISCLOSURE          This power supply for a high intensity gas discharge or fluorescent lamp exhibits near unity power factor with no third harmonic distortion, and facilitates highly efficient lamp operation with dimming capability, This is achieved by using an inverter to drive a resonant network that includes the lamp load.  A feedback circuit adjusts the switching rate of the inverter to equal the resonant frequency of the network.  Sinusoidal output voltage is achieved, together with voltage multiplication to a level sufficient to ignite the lamp and keep it lit during dimming.  The inverter is driven by a switching regulator that is supplied with unfiltered, rectified ac power.  A filter capacitor, connected across the regulator output, is sufficiently large so as to filter at the frequency of the rectified ac input.  The regulator switching duty cycle is controlled in response to the average dc level across this filter capacitor. Lamp dimming is achieved either by adjusting the switching regulator dc output level or by varying the duty cycle of the inverter.  The high power factor low distortion regulator concept may also be applied in other application where direct current power is derived from an ac line.                    -i-
