Abstract: An apparatus (10) is disclosed including a web of film (20) extending between first and second pairs of pinch rollers (12-15) and onto a vacuum table (18). A rotary cutter (46) positioned before the first pair of pinch rollers (12, 13) includes laterally extending and spaced knives (52) for creating cuts (54, 58) in the film (20) which expand into vent openings (54') positioned over the sides (68) of the product (72) when the film (20) is wrapped around and shrunk upon the product (72). A further rotary cutter (30) positioned between the pairs of pinch rollers (12-15) includes a cut-off knife (36) and first and second blades (44). The cut-off knife (36) creates a cut (60) in the film (20) to form a single sheet of film (20) and includes notches (38) in its cutting edge to form tie strips (62) connecting the single sheet to the web of film (20).

Abstract: A device (10) is disclosed for intercepting the input of a system (23) of an internal combustion engine (12) normally provided to a solenoid valve (22) for actuating a fan clutch (20) when rotation of a fan (16) is desired. The input is received by terminals (42, 43) and is conditioned and passed on to a timer (96) and a controller (97). A vacuum switch (24) senses whether the fan (16) is rotating and provides a second input to the controller (97). In the event that an input is provided by the system (23) and the time delay signal has been provided by the timer (96) and also in the event that an input is provided by the system (23), the time delay has expired, and the second input is provided by the vacuum switch (24), the controller (97) provides an actuation output to terminals (71, 73) connected to the solenoid valve (22) by use of actuation provisions (98) to actuate the fan clutch (20).

Abstract: Device and method for treating mammalian bone deficiencies, defects, voids and conformational discontinuities produced by congenital deformities, osseous and/or soft tissue pathology, traumatic injuries and functional atrophy is described. The device is a one piece molded body member composed of four substances, each of which contributes to the device, a specific requirement (or requirements) for osteogenesis and/or osteoneogenesis. Taken as a whole, the functions of these device constituents are integrated into a single body member which, when implanted into a bone defect, has the capacity to restore functional architecture and mechanical integrity, initiate osteoinduction and osteogenesis, and maintain the biological processes of bone formation and remodeling while the host organism is simultaneously biodegrading the body member.

A bottom plate extends from a lower portion of the second lengthwise wall. A supporting plate extends upwardly from the bottom plate. An upright plate extends downwardly from the bottom wall, and an inlet opening is defined between the upright plate and the supporting plate. A spraying device includes an L-shaped plate having a vertical section extending downwardly from the bottom wall. A baffle extends upwardly from a horizontal section of the L-shaped plate and a space is defined between the L-shaped plate and the baffle. A passage is defined between the baffle and the upright plate. A wiper plate extends downwardly from a lower portion of the baffle and a channel is defined between the wiper plate and the supporting plate.

Abstract: A pump (10) is disclosed including an integral clutch and including a housing (26) divided into a clutch zone and a pump zone by a dividing wall (58). An input shaft (12) including a clutch spider (16) is rotatably mounted by a ball roller bearing (54) to a clutch end plate (50). An output shaft (14) is rotatably mounted by linear roller bearings (62, 76) to a pump end plate (68) and the dividing wall (58). A disk pack (20) is slideably mounted to the clutch spider (16) and the output shaft (14) and sandwiched by a piston (34) moved by fluid pressure outward relative to a pressure cylinder (36) and against a pressure plate (28) removably connected to the axial end of the output shaft (14). Thus, axial clutch actuation loads are transmitted only through the disk pack (20) and not to any of the bearings (54, 62, 76). The free axially outer end of the output shaft (14) extends through the pump zone and is located in the pump end plate (68).

Abstract: An automatic X ray developing device comprises a base platform, four support legs disposed beneath four corners of the base platform respectively, a rotating disk and a motor disposed beneath the base platform, a plurality of rollers disposed on the base platform, a cylindrical container disposed on the base platform, a clamp seat disposed on the base platform, and a U-shaped seat disposed on the rollers. Three vessels are disposed in the cylindrical container. The cylindrical container, the base platform, and the rotating disk are fastened together. The motor has a shaft. A driving wheel encloses the shaft of the motor. The rotating disk abuts the driving wheel. A clamp holder has an extended rod, a hooked end connected to the extended rod, and a clamp hanging on the extended rod. The clamp clamps an X ray film. The hooked end is disposed on the clamp seat.

Abstract: A mobile sod cutting machine has mounting arms that have a central axis of elongation with a cable installer mechanism mounted to the lower end of one of the arms for being reciprocated with the arm. The cable installer mechanism includes a vertical ground slitting blade having a front slitting edge, a bottom edge intersecting the slitting edge and a shank mounting portion mounted to the mounting arm. An upper cable guide is attached to the shank mounting portion to extend rearwardly of the central axis of elongation of the mounting arm while a bottom cable guide is mounted to the blade adjacent to the intersection of the blade bottom edge and slitting edge to have its reversely bent edge forwardly of the central axis of elongation but spaced rearwardly of the blade bottom edge along the guide length by a distance about as least as great as the reciprocal fore and aft movement of the blade.

Abstract: An improved method or process and device for treating and healing a bone void is disclosed, and in particular a method employing a surfactant for efficiently incorporating a biologically active agent into the interstices (voids or pores) of a porous hydrophobic biodegradable material wherein the biologically active agent is deposited on the internal surfaces defining the voids or pores of the biodegradable material. The biodegradable body or device, now containing surfactant and a biologically active agent in the body itself as well as on the external surfaces and the internal surfaces defining the voids or pores, is then applied into the bone void or cavity.

Abstract: An axle assembly (10) is disclosed including a carrier (24) having side edges extending intermediate the frame rails (14) of a truck 12 and supports (28) secured to the frame rails (14). The carrier (24) is moved relative to the frame rails (14) by a screw (32) rotated about an axis by a hydraulic motor (36) to move a collar (40) threaded thereon and secured to the carrier (24). The carrier (24) is selectively locked in position relative to the frame rails (14) by simultaneously sliding first and second pins (44) slideably mounted to the carrier (24) into seats (58) fixed to the frame rails (14). The first ends of a pair of arms (66) are secured to an axle (60) having steerable wheels (62) while the opposite ends are pivotally mounted to the carrier (24). The arms (66) are pivoted relative to the carrier (24) by an actuator (70) to move the wheels (62) between ground-engaging and elevated positions.
