摘要： Apparatus for handling an oval, toroidal core, such as a sand core used in the manufacture of tubes or tires. In the handling and wrapping of the core, it is a requirement that an unwrapped or partially wrapped core will have a properly prepared surface for further wrapping to ensure that the final manufactured tire will be free from blemishes and be perfectly balanced. Thus, any material handling mechanism used to move or turn the core cannot damage or scuff the core. Accordingly, a lift fixture is provided for moving and turning the core without damage and scuffing. The lift fixture (10) for holding and centering a core (93) includes a handling ring (16) defined by a yoke (17) and a clamp slide (20) mounted on the yoke, jack (48) for closing the clamp slide (20), a support apparatus (12) for positioning the handling ring (16), and a plurality of angularly spaced holding mechanisms (33, 34, 40, 41) for gripping the core (93). The holding mechanisms (33, 34, 40, 41) are movably mounted to the handling ring (16) so as to move relative to the ring along a line generally tangent to the core (93). The holding mechanisms (33, 34, 40, 41) are biased to a centered position, as by springs (87, 88), so that when the core (93) is lifted, it is urged to a centered position within the ring (16).

摘要： A sand core pattern (11) for producing a one-piece coast wheel (10) having a radially inner shell (12), a radially outer blade support (13), and a plurality of angled blades (14) extending in a spaced, annular array (22). The pattern includes a plurality of similar segments (15), each having an inner end portion (18) defining a portion of the profile of the shell, and an outer end portion (21) defining the profile of the blade. The segments are supported in annular array about a mandrel (25) and are circumscribed by a split ring (26) defining the pattern for the outer blade support portion of the wheel (10). The inner portions of the segments are defined by angled side surfaces (16, 17) which, in alternate ones of the segments in annular array, converge and diverge toward the center of the array. Upon completion of the forming of the sand mold about the pattern, the mandrel and outer ring are removed, permitting the segments having the inwardly diverging side faces to be withdrawn inwardly from the array and permit the remaining segments then to be withdrawn inwardly therefrom.

摘要： A slant axis rotary piston mechanism including a shaft (42) having an angularly offset eccentric (44) and a housing (10) defining a general spherical chamber (22) journalling the shaft and containing the eccentric. A peripheral, generally sinuous partition (20) is fixed in the housing and extends radially into the chamber towards the eccentric. A rotor (62) is journalled on the eccentric and is of generally spherical exterior configuration (64) and has a peripheral groove (66, 68, 70) extending about and opening to its periphery. Each of the sides (66 and 68) of the groove face a corresponding side (24, 26) of the partition and define therewith at least two working volumes of variable volume. Gears (108, 110) synchronize relative movement between the shaft, the rotor and the housing, and ports (90, 92, 94, 96) provide for ingress and egress of working fluid to the working volumes.

摘要： Low stress heat exchanger (50) and method for making the same wherein thin heat exchange members (18, 20, 64, 66) are joined to thicker support members (44, 84) by causing the thin members (18, 20, 64, 66) to extend tangentially from a radiused surface (84) of the support member (44, 84). The thin members (18, 20, 64, 66) are then secured to the support member (44, 84) in an area (42, 88) remote from the area (46, 48) where the thin members (18, 20, 64, 66) extend tangentially from the support member (44, 84). The heat exchanger (50) includes closure tabs (14, 16) for bridging a space at the ends of fluid passages (36) defined by spaced wall members (18, 20).

摘要： Rotary expansible chamber devices include slant-axis rotary apparatus such as engines, compressors, pumps, and the like. Eccentric rotating members of such apparatus generate thrust and bending loads of high magnitude during operation thereof. The rotor shaft of the apparatus is subjected to severe bending and thrust loads which tend to fatigue various connections in the apparatus. The present invention provides a connection for counteracting the bending loads, including a bolt (21) extending through a rotor shaft (15), a nut (28) threadably mounted (27) on an end of the rotor shaft, and portions (30, 31) of the rotor shaft (15) and bolt (21) which are disposed closely adjacent to the nut (28) and are further disposed in press-fit relationship relative to each other. Thus, bending loads imposed on the rotor shaft are transmitted directly to the bolt but not to the screw threads during operation of the apparatus.

摘要： A vehicle safety belt system with a retractor lock device which includes a retractor (40), a belt (50) terminating in a male buckle member (52), a female buckle member (60), and a retractor lock device (20). The retractor lock device (20) includes a lock member (30), a base member (21) having an anchor bolt (22) attached thereto, a spring (23) and a guide bolt (24). The lock member (30) is movable between a disengaged position and an engaged position, the spring (23) normally urging the lock member (30) into the disengaged position. When the male buckle member is inserted into the female buckle member, it moves the lock member (30) into engagement with the retractor (40), thereby preventing rotation of the retractor.

摘要： A fluid motor control system (11) assures that automatic changes of motor displacement, which are initiated by occurrence of a predetermined operational condition in the system (11), result in a change of motor speed of the desired magnitude. Flow adjustment elements (76) respond to a displacement increase by reducing the flow of working fluid available to the motor or motors (12, 13) and respond to a motor displacement reduction by increasing the available flow. In one specific form, the system (11) controls a pair of right and left side vehicle drive motors (12, 13) and automatically increases motor displacements while reducing the fluid flow supplied to the motors (12, 13) to reduce travel speed during a turn of travel direction.

摘要： An engine enclosure (10) has a noise suppression arrangement (15, 15a, 15b) mounted thereon including a plurality of acoustical energy absorbers (20, 20a, 20b) and sound reflectors (24, 24a, 24b) spaced from the absorbers to provide airflow passages (26, 26a, 26b) therebetween. The noise suppression arrangement (15, 15a, 15b) efficiently absorbs and reflects acoustical energy and exhibits a low space to sound absorption efficiency ratio in comparison to conventional noise suppression arrangements.
