摘要:
A system for lapping gear sets with a ring gear and a pinion gear. The system includes a lapping machine tool and a robot. The lapping machine tool has a first spindle and a second spindle. The second spindle is rotatable about an axis that is generally perpendicular to a rotational axis of the first spindle. The lapping machine tool has a loading zone for loading the first and second spindles. The robot has an end effector with a first end that is configured to hold one of the gear sets. The robot is configured to position the first end of the end effector into the loading zone and to load the first gear set to the lapping machine tool without removing the end effector from the loading zone such that the ring gear is loaded onto the first spindle and the pinion gear is loaded onto the second spindle.

A synthetic-resin pipe fitting having a plurality of tubular arms, at least one of which is provided with an annular transverse flange, is provided with a coupling ring by heating the flange to a temperature above the crystallite melting point or the glass-transition temperature, and forcing the ring over the flange. The fitting is made from a memory-effect synthetic resin, preferably cross-linked polyethylene, so that upon cooling the flange is restored to its original relatively rigid condition and undeflected configuration.

A structural mounting for a heavy machinery with rotating parts being supported between a foundation surface and the heavy machinery is disclosed which includes an impermeable foundation surface supporting spaced apart columns of epoxy or similar grouting material with epoxy or similar grouting material chocks extending from the plurality of columns to the support frame of the heavy machinery or engine which provide a non-adherent support between the columns and the engine mounting frame. The columns surround but do not adhere to anchor bolts secured in the foundation. The epoxy chocks likewise do not adhere to the anchor bolts. The anchor bolts are protected with a shroud or wrapping of suitable material whereby post tensioning of the anchor bolts will not cause the columns or chocks to crack or fracture. Leveling screws threadedly engaged through the mounting flange of the machine may or may not extend through the chocks and seat upon leveling plates. The columns and chocks are formed in situ. The structural supports disclosed may be used for new installations or replacement of previous installations after the existing installation has been removed in a suitable manner. After the heavy machinery has been aligned and leveled, the leveling screws and any jack screws are released and the anchor bolts are tensioned to a suitable torque.

An improved combustion element for a radiant energy burner. The element comprises a generally cylindrical metal screen having its outer end closed off by an end closure, while the inner end is connected to a source of gaseous fuel. Strands of ceramic material are braided directly on the outer surface of the screen to form a braided sleeve which is snugly fitted over the entire periphery of the screen.

Disclosed is a method of manufacturing a composite material burner ring made wholly of a composite material. The burner ring is manufactured by winding a carbon or ceramic type refractory material about a toroidal form until a specific material thickness is obtained. The burner ring elements, such as radial arms, fastening clips or fuel feed tubes are then fastened onto the winding. Each of the elements may be formed in mirror-image halves and may be assembled onto the burner ring body in adjacent pairs, each one of the pairs facing in an opposite direction. The winding of the composite material is continued until a final thickness is obtained, thereby integrally attaching the burner ring elements to the burner ring body. The assembly is then subjected to a carbonization or ceramization head treating process. After this process, the burner ring body is cut along a plane extending generally perpendicular to the longitudinal axis of the toroidal form such that two burner ring assemblies having gutter-shaped cross-sections are formed when removed from the toroidal form.

Assembly device of tubes of low carbon ferritic stainless steel having 17 to 18.5% by weight of chromium on a tube-plate of carbon steel. It includes a first overlay of low carbon austenitic stainless steel having 11.50 to 14% by weight of nickel and 22 to 25% by weight of chromium on the surface of the tube-plate opposite the plurality of tubes, a second overlay on the first of low carbon austenitic stainless steel having 10 to 12% by weight of nickel and 19 to 23% by weight of chromium extending beyond the upper level of the ends of the tubes, and weld beads with or without filling metal around these ends between these ends and the stainless steel of the second overlay.
