Title: Elongate material spreading and tacking apparatus  and method
Inventor: KRAPS MICHAEL H
IPC: B60C25/18
Filed: 1980-03-11
Granted: 1982-06-15
Abstract: Elongate Material Spreading and Tacking Apparatus and Method Abstract An apparatus and method is provided for heat tacking of elongate material or cables to a tire car-cass on both peripheral sides of a core opening, spreading the elongate material or cables lying over the core opening so as to position the elongate material or cables on either circumferential side of the core opening, and heat tacking the spread elongate material or cables to the tire carcass.  The apparatus includes a frame having locating pads for positioning the heat-tacking and elongate material or cable-spreading subassembly with respect to the core opening.  The tacking members are preheated to a tacking temperature so that when the frame is clamped onto the carcass, and the elongate material or cables are spread, the spread elongate material or cables are tacked to the carcass.  A core plug may act as the elongate material or cable-spreading member and may be optionally removed when the frame is removed from the carcass.

Abstract: A METHOD OF ASSEMBLYING A SEALED STRUCTURE         ABSTRACT OF THE DISCLOSURE         A method of connecting a first shell to a second shell to establish a unitary sealed structure.  A bead of a diaphragm assembly is connected to a first peripheral surface on the first shell to establish a first sealing surface and to define a first chamber between the diaphragm assembly and the first shell.  A spring attached to the diaphragm assembly engages the second shell.  A force applied to the second shell compresses the spring to bring a second peripheral surface thereon into engagement with the bead on the diaphragm to establish a second sealing surface and define a second chamber between the diaphragm assembly and the second shell.  A vacuum evacuates air from the first and second chambers to establish a pressure differential between the first and second chambers and the surrounding environment.  This pressure differential acts on the first and second shells to urge the first and second peripheral surfaces against the diaphragm to establish a unitary structure.  Thereafter, the force applied to hold the first and second shells together is removed and the relationship between the first and second sealing surfaces is observed for a fixed time period.  Should air from the surrounding environment enter into either the first or second chamber, the pressure differential is sufficiently reduced to allow the spring to separate the first and second shells to indicate a non-conformity between the first and second shells and the diaphragm.  If the first and second shells remain together during the fixed time period, the first and second peripheral surfaces are thereafter crimped together to establish the unitary sealed structure.

Abstract: ABSTRACT OF THE DISCLOSURE:           A process for preparing dimethylcarbonate by reacting methanol with mixtures of carbon monoxide and oxygen which also contain hydrogen.  The catalyst is constituted by a salt of a metal of groups IB, IIB or VIII of the periodic system, dissolved or dispersed in the reac-tion medium.  It has been found that the hydrogen does not interfere in the reaction, so that a hydrogen-enriched gaseous mixture (synthesis gas) is withdrawn from the reactor.  It is therefore particularly advantageous in that it produces dimethylcarbonate and at the same time provides hydrogen-enriched synthesis gas.

Title: Fuel supply and ignition control system employing flame sensing via spark electrodes

Abstract: FUEL SUPPLY AND IGNITION CONTROL SYSTEM EMPLOYING FLAME SENSING VIA SPARK ELECTRODES Abstract: A fuel supply and ignition control system for con-trolling the operation of pilot and main valves in an intermittent pilot type system. At the start of an igni-tion cycle, the pilot valve is operated to supply fuel to a pilot outlet for ignition by sparks generated by a spark generating circuit. When the pilot fuel is ignited, the pilot flame bridges the spark gap, and a flame sensing network, which is connected in circuit with the spark electrodes, generates a flame signal which is applied to an enabling circuit which responsively effects operation of the main valve. The enabling circuit includes a con-trollable switching device which in one embodiment, is maintained disabled in the absence of a flame signal and is enabled to cause a flame relay to operate and ener-gize the main valve when a flame signal is provided. In another embodiment, the controllable switching device is enabled in the absence of a flame signal and causes an SCR device to conduct, providing a low impedance energizing path for the pilot valve operate winding and a shunt path around the main valve operate winding. When a flame bridges the spark gap, the flame signal disables the switching device so that the SCR device is rendered non-conducting, interrupting the shunt path amount the main valve winding allowing the main valve to operate.
