Patent CA-2086963-C (CA)
Title: Insert spacer assembly
Inventor: WOODS GERALD L
IPC: E21B10/58
Filed: 1993-01-08
Granted: 1997-03-18
Abstract: A center vacuum rotary drill bit including a rotary drill bit body, an insert and an insert spacer assembly.  The rotary drill bit body includes a top working surface having a slot extending transversely across the top working surface.  The slot includes a first sidewall, an opposite second sidewall and a generally horizontal bottom surface extending between the first sidewall and the second sidewall.  The insert includes a pair of oppositely facing generally parallel side surfaces, a pair of oppositely facing generally parallel end surfaces extending between and interconnecting the side surfaces, a pair of oppositely inclined top surfaces extending between and interconnecting the side and end pairs of surfaces, and a bottom surface extending transversely to and interconnecting the side and end pairs of surfaces. The insert spacer assembly includes a shim and a spacer bar.  The shim has a pair of upstanding spaced sidewalls and a bottom wall extending in transverse relation between and integrally connecting the sidewalls.  The spacer bar is of a generally parallelogram configuration.  The insert spacer assembly is interposed between the insert and the slot to elevate the insert with respect to the top working surface of the rotary drill bit body.  In a preferred embodiment, the modulus of elasticity of the shim is less than the modulus of elasticity of the spacer bar to effectively distribute the force of drilling to the drill bit body and reduce the stress load on the insert.

Abstract: A butt connection in the form of a corner or T-connection is so configured that the stiffeners that are used to align the butt joint can be installed in the particular corner or butt area after connection has been effected by means of the profile connectors. Furthermore, the use of a sealant to seal the area of the butt joint after installation is also made possible.      The stiffener (24) of the butt connection according to the present invention is an elastically deformable sheet metal or plastic part which rests under tension on the inside profile webs (18, 20, 21) that define the particular stop (12). The stiffener (24) can be inserted into the inside or outside corner subsequently. To this end, it is not necessary that the grooves be under-cut. Providing that the stiffener (24) is provided with bores (28, 29), a sealing compound can be injected into the butt area subsequently by using a cartridge. The butt connection according to the present invention can be used, in particular, for windows and doors produced from aluminum compound profiles.

Abstract: The counting disk (1) has circumferential sections (2) arranged on its border, and each circumferential section has a suction hollow (4) in which suction openings (5a to 5f) located one behind the other are arranged. Upon rotation of the counting disk, said suction openings are connected intermittently to a suction-air source, with the result that the corners of a sheet stack, one after the other, are subjected to suction, deformed, separated from the rest of the sheets and, by virtue of a pneumatic counting pulse being produced, counted. The suction air is supplied to the suction openings (5a to 5f) via a duct (6, 7) whose section (7), which opens into the suction openings, is directed perpendicularly with respect to the plane of the counting disk. Moreover, the suction openings (5a to 5f) are located in the center of the suction hollow (4).

Abstract: A conductive structure for use in microwave food packaging which adapts itself to heat food articles in a safer, more uniform manner is disclosed. The structure includes a conductive layer (103) disposed on a non-conductive substrate (101). Provision in the structure's conductive layer (103) of fuse links (109) and base areas (107) causes microwave induced currents to be channeled through the fuse links (109), resulting in a controlled heating. When over-exposed to microwave energy, fuses break more readily than the conductive base areas (107) resulting in less absorption of microwave energy in the area of fuse breaks than in other regions where fuses do not break. In this way the fused microwave conductive structure compensates for the uneven microwave field within a microwave oven and at the same time provides a safer conductive structure less likely to overheat. In addition, by varying the dimensions of the fuse links and base areas it is possible to design and fabricate different fused microwave conductive struc tures having a wide range of heating characteristics. T hus, a fused microwave conductive structure permits food heating temperatures to b e tuned for food type.
