Patent CA-2077113-A1 (CA)
Inventor: GUTGSELL DAVID R
IPC: A47B87/00
Filed: 1992-08-28
Abstract: An apparatus for interconnecting table tops and table leaves comprises a number of complementary bracket assemblies and thumbscrew fasteners mounted to juxtaposed table tops or leaves.  The bracket assemblies include a bracket having a pivot end, a connection end, and a first slot defining an arcuate opening between the two ends.  The bracket is pivotably connected at its pivot end to a first table top.  A fastener extending through the first slot and fastened to the table top limits the degree of pivoting of the bracket between a first position in which the bracket projects beyond the edge of the first table top and a second position in which the bracket is retracted completely beneath the first table top.  A second slot is defined at the connection end of the bracket for engaging one of the thumbscrew fasteners in the second table top.  In one embodiment, the second slot provides for linear engagement, requiring extension of the bracket and then physical movement of the table tops together.  In a second embodiment, the second slot is arcuate, permitting engagement with the thumbscrew fastener of a second table when the first and second table tops are already juxtaposed.  In a third embodiment, the second slot is a closed-ended slot as a safety feature for interconnection of a table leaf between two table tops.

Title: Screenless disk mill
Inventor: RADZINS EDMUND
IPC: D21B1/06
Filed: 1992-12-29
Abstract: ABSTRACT OF THE DISCLOSURE The circular housing of a fiberizer mill has a rotationally driven shaft on which there is a disk having a conical face and spaced apart rows of teeth. A stationary disk has on its face a multiplicity of annular grooves which define teeth.  There is a small gap between the tips of the rotary teeth and the tips of the stationary teeth.  The gap extends at an acute angle relative to vertical plane passing perpendicular to the shaft axis so that particles being disintegrat-ed experience a horizontal component of force.  The result is that particles, after having been exploded by striking the teeth on the stationary disk,  are emitted generally radially outwardly from the gap. Hammer bars on the periphery of the rotary disk are surrounded by a toothed circular breaker plate member concentric to the orbital path of the hammers on the rotary disk.  The flow of fibers and particles out-wardly of the gap between the rotary and stationary disks continues into the path of the hammers which smash the particles against the teeth of the circular breaker plate.   The plate has a gap in it through which the air entrained fibers are passed to an out-let.

Title: Blender with virtual baffle of particulate material
Inventor: AVERY HUGH E JR
IPC: B01F5/24
Filed: 1992-04-09
Abstract: A blending apparatus, inexpensive in construction and requiring a minimum of recirculation, is today essential for economical and thorough blending of particulate material, for example, plastic pellets of virgin material and of pellets that have been reconstituted from recycled material. Construction of the blender is low in cost not only because the customary receiver, and its piping, conventionally installed below he blender are eliminated, but because the rigid baffle of the prior blender has been replaced by a virtual baffle (626) of particulate material, which forms a toroidal block within: he sonically walls (610) of the blender; the converging blended conduits (602) adjacent thereto; and the structural supporting matrix. The baffle of particulate material (626) serves: 1) as a termination surface for the conventional perforated blending conduits; and 2) retains a toroidal annular volume of particulate material in position between the upper outer surface of the baffle and the inside wall of the blender.

Patent CA-2101895-A1 (CA)
Inventor: KLAK STEVEN P
IPC: G01F1/42
Filed: 1993-08-04
Abstract: An orifice fitting with an orifice plate centered in the flow passage of an orifice fitting via direct contact between a cradle and the orifice plate. The orifice plate is centered via the use of an orifice plate carrier having two channels on its downstream side and two slots located in the bottom portion of the seat, which is located on the plate carrier's upstream side. The plate fits into the seat and a bottom portion of the plate's peripheral edge protrudes through the slots. A cradle having locating surfaces fits through the channels in the orifice plate carrier and firmly holds the orifice plate against the orifice plate carrier. The cradle can be positioned and then secured in place by two adjustable set screws and a stem piece of the cradle. Once the orifice plate has been centered via the positioning of the cradle, the stem piece of the cradle and the set screws can be welded into the body of the orifice fitting.  Alternatively, the cradle may be formed from weld metal added to the body of the orifice fitting and machined to define the cradle, or can be machined from a portion of the cast metal cradle. The method of the present invention involves the use of a cradle having locating surfaces to center an orifice plate in an orifice fitting by inserting the locating surfaces of the cradle in channels in an orifice plate carrier so that the locating surfaces contact and hold a bottom portion of the peripheral edge of the orifice plate and then positioning the cradle so as to center the plate.

Patent CA-2104241-A1 (CA)
Title: Socket Wrench Extension with Lock
Inventor: BEARDSLEY GILBERT D
IPC: B25B23/00
Filed: 1993-08-17
Abstract: A socket tool extension element includes a latching mechan-ism for automatically securing a socket to a driven stud on one end of the extension simultaneously with the attachment of a wrench drive stud to a socket portion at the opposite end of the extension. A captive latch ball projecting from an opening on one side face of the driven stud is constantly biased to the projected position by one end of a compression spring housed within a latching bore angularly disposed relative the longitu-dinal axis of the extension element. The other end of the com-pression spring constantly engages a bearing member which in turn biases against a lock pin slidably disposed within a bore axially extending from the socket portion to the driven stud of the extension element. In an at-rest condition and with a socket attached to the driven stud, the socket is manually attachable and removable from the driven stud and temporarily retained thereupon by the yieldably biased latch ball. Thereafter, upon the attachment of a wrench drive stud to the extension socket portion, the drive stud engages an end of the lock pin, causing its axial displacement to force the bearing member toward the captive latch ball and full compressing the helicies of the compression spring so as to preclude any inward deflection of the latch ball such that the attached socket is non-removably re-tained or locked upon the extension element as long as the wrench drive stud is connected thereto. To maximize the space available for containment of a compression spring of sufficient length to function as herein described. the axial bore through the exten-sion element is preferably disposed off-center or asymmetrically of the center of the extension element. To provide even greater space for accommodation of the compression spring; the latch ball and bearing member, the latching bore may be oriented obliquely relative the extension longitudinal axis. Still further optimi-zation of space is achieved by employing a cup-shaped element as the bearing member and wherein an end of the compression spring including several of its helicies is constantly disposed there-within.
