Abstract: The roller cage of a roller bearing has lubrication grooves extending at an angle across the radially inside surface of one of the cage annular end rings.

Abstract: The thrust bearing fits on a rotatable shaft having an annular groove or in a rotatable housing with an annular groove. One of the thrust bearing races has an axially extending flange with deflective tabs projecting from the flange. The deflective tabs deflect radially when the race is pushed over the end of the rotatable shaft or into a rotatable housing. The deflected tabs spring back into the annular groove when the thrust bearing is fully seated.

Abstract: Axially spaced cams and bearing rings mounted on a tube are permanently secured to the tube by circumferentially spaced projections on the tube extending into grooves formed on the inside surfaces of the cams and bearing rings.

Abstract: A pulp feeder feeds the pulp from the pulp feeder housing to the pump impeller. The impeller is provided with vanes specially constructed to provide channels of sufficient dimension to permit the flow of the pulp through the channels. The impeller also has helical flights for feeding the pulp to the channels. The end of the pulp feeder is spaced close enough to the impeller to feed the pulp to the impeller flights but far enough away from the impeller to not interfere with the removal of air. An air removal pipe may also be included in the pulp feeder housing.

Abstract: An X-Y position indicator control for manual movement over any surface to move a cursor over a display on a cathode ray tube, the indicator control generating signals indicating its position to cause a cursor to be displayed on the tube at the corresponding position. The indicator control mechanism contains X-Y position wheels mounted with their axes in perpendicular planes, which rotate according to the X and Y movements of the mechanism. Each position wheel is mounted on a flexible shaft. Each position wheel is resiliently urged into contact with the surface by the flexible shaft.

Abstract: A screen and a coaxially radially spaced rotor provide a fluid passage for the fibrous material--liquid suspension. The rotor surface has the effect of pumping or assisting a flow of dilution liquid from the reject end towards the inlet end of the fluid passage, thereby partly or wholly offsetting the natural thickening of the suspension during screening.

Abstract: The breakaway vehicular steering assembly has a tube and a shaft normally operable as a unit. The tube and the shaft are held together by a shearpin which will shear at the application of a predetermined axial force.A portion of the tube is channelled; the shaft fits within the channel. A ramp extending from the walls of the tube is adapted to move the shaft outwardly from the channel after the shearpin has been broken and the shaft moved axially within the channel and along the ramp. As the shaft moves out from the channel, a metal band innerconnecting the side walls of the channel is broken at a predetermined force and alignment tabs extending outwardly from the tops of the side walls of the channel in the tube are expanded so that the shaft is completely removed from the channel.

Abstract: A steering column for a vehicle and a method of making same, wherein the steering column is made from a tube which has a sleeve passed over a length of it in the region where the steering column is to be engaged by a steering lock mechanism, in order for there to be sufficient thickness in that region to accommodate a lock slot of the steering lock mechanism.In order to achieve substantially the same overall outer diameter along the major length of the steering column, the sleeve is secured to the tube, for example, by welding and the sleeve and underlying tube are crushed by swaging or a die forming machine so that the outer diameter of the sleeve becomes substantially the same as that of the tube beyond the sleeve.

Abstract: The bearing is used on a mechanical machine part or apparatus part which allows linear movement of the part along a second machine part or apparatus part and also allows angularity of one part with respect to the second part. A generally rectangular roller block is provided with raceways around its entire periphery. Rollers fill all of the raceways. Two opposite raceways have their rollers enclosed; the other opposite raceways have rollers which are in exposed operating positions so that they may contact the second machine. The rollers are retained within the roller block by one or more roller retaining members.

Abstract: The ball bearing assembly includes an outer race, an inner race, and a ball cage. The cage is molded of a resilient plastic material and has features located on one rim which retains the outer race and inner race in the assembly.

Abstract: This is a multirow bearing for supporting a work or back-up roll of a rolling mill. A seal case is fitted within the annulus between the inner races and outer races. The seal case is configured to fit entirely within the annulus. The seal cases have elastromeric portions which cooperate with an inner race to form barriers at the ends of the bearing.The inner races may comprise a pair of inner races separated by a sealed spacer.

Abstract: The universal joint cross includes a solidified molded plastic hub around the center of the cross. The hub has four integral flexible seals surrounding the pins in the cross. Each seal provides an external seal for a bearing mounted on each of the four exposed pin ends.

Abstract: Pre-heated mash is pelleted. The resulting warm pellets are cooled by the ambient air and the ambient air is heated by the warm pellets. The heated ambient air is used to pre-heat the mash.

Abstract: An outer cup made from flat sheet metal encloses an inner cup also made from flat sheet metal. The inner cup has an open end adapted to receive the end of a rotatable member, such as a shaft. The other end of the inner cup has a closed end axially spaced from the closed end of the outer cup to provide a lubricant reservoir in communication with the rollers in the annular space between the cups.

Abstract: The external seal is mounted on a housing about a rotary shaft projecting through an opening in the housing. The seal is a resilient, flexible member having a generally tubular body portion with an annular lip extending radially outwardly from one end of the body portion and a flange extending radially outwardly from the other end of the body portion. The lip extends into a sealing chamber formed by the outside of the housing and a replaceable sealing member which has an inside surface spaced from and parallel to the outside of the housing. The tubular portion of the seal extends through an annulus formed by the shaft and the replaceable member. The outwardly extending flange is used to prevent the clamp holding the seal to the shaft from falling out.

Abstract: The driving shaft has an end shaped to overlap the end of the driven shaft. The two shafts are interconnected by a coupling member. The coupling member is connected to the driven shaft by a long pin. The overlapping portion of the driving shaft is connected to the coupling member by two short pins. A preload spring mechanism applies preload forces against the two shafts.

Abstract: An X-Y position indicator control for manual movement over any surface to move a cursor over the display on a cathode ray tube, the indicator control generating signals indicating its position to cause a cursor to be displayed on the tube at the corresponding position. The indicator control mechanism contains X-Y position wheels mounted with their axes in perpendicular planes, which rotate according to the X and Y movements of the mechanism. As the position indicator control is moved along a surface each position wheel is resiliently urged into contact with the surface.

Abstract: The bearing comprises a roller race formed from flat sheet material. The roller race has a roller raceway and an indent. A plurality of rollers are in contact with the roller raceway and are located in the roller race. A split ring spring member provides an axial thrust face for the rollers.The formed roller race is heat-treated. The rollers are inserted into the formed race in a single step; the split ring spring member is then placed into the indent to provide the axial thrust face for the rollers.

Abstract: The sub-assembly includes a telescopically arranged rotatable driving shaft and rotatable driven shaft. Both shafts are substantially triangular in cross-section. A spring provides a pre-determined spring force having a magnitude to permit one shaft to slide within the other shaft. The complementary triangular shapes of the shafts causes the torque from the driving shaft to be transmitted to the driven shaft without rotational lash.

Abstract: A radial roller bearing and a bi-directional ball bearing are mounted in the annular space separating a rotatable outer member and a stationary inner member. The bi-directional ball bearing has a pressed metal cup with a radially extending end flange. Balls and at least one thrust plate is provided in the metal cup.The dimensions and locations of the cup, balls, and thrust plates are such that an axial force on the pressed metal cup in a predetermined axial direction causes the end flange to come into contact with either the balls or a thrust plate, depending on their axial locations within the cup, and an axial force in the other axial direction causes the end flange to break such contact.
