Abstract: A seal ring having first and second semicircular metal ring segments, each segment having first and second ends, the first end of the first segment having an interference interfit with the first end of the second segment, and the second end of the first segment having an interference fit with the second end of the second segment, to form the seal ring; the segments being separable or interconnectable by temporary deformation thereof, the first and second ends of the first segment having a radially convex surface and the first and second ends of the second segment having a radially concave surface of matching configuration to the convex surface, to form the interference interfit. A method of forming a metal seal ring of separable semicircular segments of a predetermined diameter by providing an annular metal ring workpiece, wire EDM cutting transversely through the ring workpiece at a first circumferential location to form a first set of two adjacent ends, cutting a circumferentially extending shoulder on the radially inner portion of one of the adjacent ends and an opposite circumferentially extending shoulder on the radially outer portion of the other adjacent end, wire EDM cutting transversely through the ring workpiece at a second circumferential location diametrically opposite the first circumferential location, to separate the ring and thereby form a second set of two adjacent ends, forming by said cutting at the second location a circumferentially extending shoulder on the radially inner portion of one of the second set of adjacent ends and an opposite circumferentially extending shoulder on the radially outer portion of the other of the second set of adjacent ends, the cutting steps forming a pair of semicircular ring segments and including forming of interfitted, radially oriented, concave and convex surfaces on the first and second shoulders to create an interference fit and thereby allow the seal ring to be snap fitted together to form the seal ring separable into the two segments as necessary.

Inventor: BRUNO ADRIAN A
IPC: A21B1/48
Filed: 1998-11-05
Abstract: A plurality of small, low cost conveyor toaster/oven can be stacked with substantially no physical spacing is required between the units. In part the stackability results from a blower/fan that drives cooling air through a common plenum surrounding the conveyor. The cooling air is sucked into one sides of the unit and then divided between the lower motor compartment and the upper air plenum flowing over the top and bottom ef the oven. The air is then recombined to cool the rear compartment and exits the unit via several vents in the back and opposite side of the oven. A control panel enables the user to pre-select different menu schedules which can be modified, as required. Each selection is identified by a single digit on a key pad in the control panel. The actual temperature within the toaster/oven is sensed by a thermocouple in contact with the heater element sheath. The control converts the stored data via a mathematical function and in response to temperatures sensed on the heater. In order to provide both toasting and hearth baking the conveyor may be equipped with either of two types of endless belts, one being a tightly woven herringbone belting material that hearth bakes the food product. The other type of endless belt is made of an open wire link belting material.

Abstract: The invention is an electrically insulated steel railway cross tie for use with railway tracks using track circuit systems. The electrically insulated steel cross tie prevents the cross tie for shorting the track circuit systems. A method of manufacturing the electrically insulated steel cross tie is to transversely cut an uninsulated steel cross tie into separate elongated members. The elongated members are then re-joined end to end with an insulator member interposed between the elongated members. The insulator member prevents electrical current from being conducted from one elongated member to another elongated member. In the preferred embodiment end plates are welded to the cut ends of the elongated members and bolts are used to releasably join the elongated members together. The bolts are electrically insulated to prevent the bolts from conducting electrical current between the elongated members.
