Abstract: A hub assembly (10) for use in arranging muntins (22) across a window pane includes at least first and second covers (12, 14) which are snap-fit and frictionally held together and which define at least one arcuate track (70) that is adapted to slidably receive carrier members (20) for interconnecting the muntins (22) to the hub assembly (10). The arcuate track (70) coacts with the carrier members (20) to retain the carrier members (20) in selective angular positions about the hub assembly (10). The hub assembly (10), which is semi-circular in plan view, can be selectively attached directly to a window frame, or to another similarly constructed hub assembly (10) to form a circular overall hub assembly.

Abstract: An apparatus (10) for erecting collapsed, tubular cartons (12) includes a device (32) for removing the top carton (12) of a vertical stack of cartons (12) and moving it in a horizontal orientation to an operative position, with the second side panel (16) of the collapsed carton (12) underlying at least the first end panel (18) which is in a linear arrangement with the first side panel (14). Suction cups (76) carried by a frame (74) are secured to the second side panel (16) in an attachment position and moved by a parallelogram linkage to an open position located vertically below and coinciding with the first side panel (14). After an unload arm (84) is secured to the first end panel (18), tucking arms (102, 104, 106) are pivoted to tuck the bottom closure flaps (22, 24, 25).

Abstract: An apparatus (10) for controlling the transmission of rotational forces between first (14) and second (66) members through an axially shiftable friction element (56) that rotates in unison with the first member (14) and can be selectively brought into engagement with the second member (66) is provided with a forced air cooling system that functions to cool the interface between the friction element (56) and the second member (66), as well as a first bearing (54) allowing relative rotation between the friction element (56) and an actuation member (38). A flow of cooling air is developed during operation of the apparatus by fins (172,174) formed about an outer radial surface portion of the friction element (56) and the air is caused to flow through enlarged lobe cut-out sections (156) in the second member (66) along the interface and through holes (164) formed in the friction element (56) which are arranged opposite the first bearing (54).

Abstract: A roller bushing assembly (21d, 21e, 21f) designed to enable a low tolerance, frictional fit within an out-of-round or otherwise distorted support member (5, 9) includes a bushing member (29a, 216) having an outer surface (102) machined to provide various axially spaced, annular grooves (127-130, 132 and 242-250). Between or directly adjacent respective ones of the annular grooves (127-130, 132 and 242-250) are defined a plurality of axially spaced and radially extending ribs (113-122 and 232-240). The axial outermost ribs (113, 122 and 240) are preferably elongated relative to the remaining ribs (114-121 and 232-239) and have annularly chamfered portions (124, 125 and 252). The ribs (113-122 and 232-240) are adapted to shear upon mounting of the bushing member (29a, 216) within an out-of-round or otherwise distorted support. By providing the shearable ribs (113-122 and 232-240), the bushing assembly (21d, 21e, 21f) can be effectively mounted within a greater range of varying sized support members.

Abstract: A hinge device has a first portion defined therein a channel, a lateral slot and a longitudinal slot and a second portion having an axis formed therewith and rotatably received within the channel of the first portion. The lateral slot and the longitudinal slot of the first portion are able to provide the hinge device of the invention recovery force of dual orientations according to various orientation requirement of load.

Abstract: A connector (10) for tubular members (12, 14) is disclosed including first and second connector elements (16, 18) each having U-shaped cross sections and first and second jaw members (20, 22). A set screw (30) is threaded into the central portion (24) of the second connector element (18) intermediate the first and second jaw members (20, 22) and has an end abutting with the central portion (24) of the first connector element (16). A collar (32) encircles the first and second connector elements (16, 18) and the set screw (30) intermediate the jaw members (20, 22). The first and second connector elements (16, 18) are biased together by first and second O-rings (50) positioned around the connector elements (16, 18) and on opposite sides of the set screw (30).

Abstract: A microchip handling system has a pair of probes with suction cups for handling microchips. An improved microchip holding device is used in lieu of the suction cups to pick up and hold microchips. The microchip holding device has a head accommodating an annular sleeve that retains the microchip in spaced holding relationship relative to a body. The sleeve establishes a large annular space whereby the vacuum force has a large surface area for holding the microchip in engagement with the sleeve.

Abstract: A versatile apparatus (2) for controlling the transmission of rotational forces between first and second rotatable members preferably takes the form of a clutch that can be activated by axially shifting an internal actuation member (140) through the introduction of either liquid or gaseous mediums. The clutch includes first and second transmission members (177, 281) which are rotatably mounted within a housing (5) and adapted to be attached to the first and second rotatable members respectively. A coupling assembly (226), preferably including first and second sets of axially spaced interface elements (252-254 and 274, 275), is interposed between the transmission members (177, 284) within the housing and axial movement of the actuation member (140) causes the interface elements (252-254 and 274, 275) to be frictionally engaged.
