Abstract: Mounted upon the lower jaws of a gripping and manipulating tool is an obtuse-angled adapter plate to which is secured an adjustable work positioner including a stationary work-positioning V-block and a relatively movable work-positioning block provided with a work-holding recess consisting of a notch shaped to fit the edge of the workpiece to be contour ground. The stationary V-block contains a right-angled recess which is shaped to fit and become coaxially centered with respect to a centering portion of rectangular cross-section coaxial with the work-holding spindle of the contour work-turning machine such as a contour grinder. A fastener is provided for clamping the adjustable block to the stationary block and passes through a vertical slot in the adjustable block into a threaded bore in the stationary block.

Abstract: A hydrophilic oleophobic filter medium in granular form and composed of glass beads dispersed in a matrix of cured cement. The granules may be utilized in conjunction with naturally occurring materials, e.g., sand and/or anthracite. The granular density can be predetermined and varied. The granular shape is regular and controllable and the granular size can be graded for each density, so that the granules in a given filter level are of varient size, having a uniformity coefficient ranging from about 1.2 to 1.7. The method of making such granules includes the steps of casting a sheet of desired density and thickness, partially curing the sheet, severing the partially cured sheet to polygonal granules, curing the granules, optionally tumbling the granules, and finally screening them for final sizing.

Abstract: A support for a front suspension system in vehicles is disclosed. The front suspension system support of the present invention creates an opening between side members of a frame of the vehicle which is longitudinally between the transverse axis of the vehicle front wheels. The opening is utilized to place a radiator between the front wheels of the vehicle with the radiator supported between the frame longitudinal members.

Abstract: A multi-part connector for use in constructing a wooden deck or the like. The connector comprises identical, stamped metal elements which cooperatively embrace the upper end of a vertical post and project above the post to cooperatively receive a lateral beam therebetween. The elements each have an inwardly directed flange which is either (1) partially embedded in the upper end of wooden post or (2) engages and centers a metallic pipe post between the elements. An additional apertured plate is provided for cooperation with the two elements for securing the elements together in spaced relation to the element flanges and in embracing relation to the pipe post without bolting or otherwise securing the elements to the post. In use with either a wooden post or a pipe post, the beam overlies and bears upon the flange to aid in retaining the connector elements in place. The method involves the steps of assembling the connector elements on the post and utilizing the beam to retain the elements in place.

Abstract: A vehicle door formed primarily from plastic material and a structure for reinforcing the door is disclosed. The door of the present invention includes a metal reinforcing beam extending longitudinally from an upper hinge support at a first end to a door latch at a second end. The beam has a hollow box like cross section and is affixed an inner surface of a door outer wall. A first end of the beam includes an upper hinge support, and a second end of the beam includes a latch support.

Abstract: Both a tub surround kit and a method for installing a tub surround are disclosed. The kit comprises four wall panels for covering the back and two side walls surrounding a tub, and two corner panels for covering the joints between the back wall and the two side walls surrounding the tub. The two corner panels each include a pair of orthogonally disposed flanges which terminate in flared, flexible lips for overlapping adjunct edges of the four panels, thereby joining the four wall panels together. The back faces of the flanges of each of the corner panels are adhered or otherwise affixed to the wall corners so that the flared, flexible lip or each of the flanges is yieldably deformed around the edge of the adjacent panel in overlapping relationship.

Abstract: A sheet metal slitter of the type having a pair of parallel shafts journalled at spaced axial points and a slitter roll on each shaft, the rolls cooperatively defining a cutting nip. The invention resides in a bearing assembly with bearings cantilevered from a support element. The bearings are positioned, respectively, adjacent the pair of slitter rolls on the shafts to resist forces tending to separate the shafts during metal cutting. The support element is slotted to accommodate the cut portions of the workpiece without spreading or tearing and with substantially no bending.

Abstract: A method and apparatus are disclosed for mechanically locking a movable filter shell of a pressure filter in filtration position adjacent a second fixed filter shell, in order to accommodate and resist higher internal filtering pressures. In the method, a gasket between the two filter shells is compressed to an extent greater than necessary to achieve a liquid tight seal, in response to movement of the movable shell toward the fixed shell. Next, a locking member is freely inserted between the movable shell and an abutment with clearance being provided in order to facilitate the insertion of the locking member due to the movable shell excessively compressing the gasket. Upon initiation of the filtration cycle, the movable shell is slightly displaced away from the fixed shell in response to internal filtration pressures, with the locking member preventing further displacement in order to maintain the gasket in water-tight sealing compression.

Abstract: A pollution control system for reducing the presence of fine aerosol particles in stack gases from the manufacture of glass fiber wool-type products. After larger particles are removed from the forming fan gas, the gas is fed into a centrifugal fan and massive quantities of water are injected into the fan intake. The aerosol particles are agglomerated by impact with the airborne water droplets and the wet surfaces of the fan. The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separation from the air by either the action of the fan or in a later separation operation.

Abstract: This invention proposes a method for eliminating "sink" in molded glass fiber reinforced panels for automotive and other uses. Such panels are normally formed with integrally molded reinforcement shapes (ribs) and fastening locations (bosses), and a slight depression or "sink" occurs in the exposed panel surface over the location of the ribs and bosses. The present invention proposes the elimination of this sink by utilizing innovative material and design techniques that compliment one another.The material approach makes use of dual reinforcements; normal chopped glass fibers reinforcement (1 inch or less in length) in combination with a long fiber reinforcement (2 inches or more in length) and preferably a continuous fiber reinforcement. The long fiber reinforcement is placed such that it is oriented in the panel to closely underlie the exposed panel surface.

Abstract: A pollution control system for reducing the presence of fine aerosol particles in stack gases from the manufacture of glass fiber wool-type products. After larger particles are removed from the forming fan gas, the gas is fed into a centrifugal fan and massive quantities of water are injected into the fan intake. The aerosol particles are agglomerated by impact with the airborne water droplets and the wet surfaces of the fan. The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separation from the air by either the action of the fan or in a later separation operation. It has been found that 1.5 or more gallons per minute (gpm) of injected water per thousand standard cubic feet per minute (scfm) of forming gas passing through each fan is effective to remove more than 40% of the fine, aerosol particles introduced into the fan and even larger amounts of water remove greater amounts of such particles.

Abstract: A sandwich wall for pipes, tanks, and the like fluid confining uses, wherein concentric inner and outer glass fiber reinforced plastic skins or shells are separated from one another by essentially radial ribs integrated into the shells to form a monolithic construction. The ribs are of limited axial extent and are separated from one another by rib forms of substantially greater axial extent, the rib forms functioning essentially as spacers without otherwise materially contributing to the strength or rigidity of the structure. The ribs are composed of essentially the same resinous material as the shells plus a filler, which typically can be chopped glass fiber strands, sand, or other particulate material, glass fiber mat or woven fabric, glass flakes, or mixtures of such materials. The ribs may be either helical and continuous throughout the axial extent of the wall or annular and independent of one another. Various methods of making such sandwich wall structures are also disclosed.
