Abstract: This relates to a container having a neck finish which is provided with threads for receiving a closure and wherein the threads are blow molded in the formation of the container from a tubular parison. It has been found that in the blow molding of the threads, there is a thinning of the wall of the neck finish at the roots of the threads and under certain circumstances, when a closure is applied at a high torque, there is an axial collapse of the neck finish rendering the container unfit for use. The problem of axial collapse of the neck finish is overcome by interrupting the threads so as to provide axial beam strength at circumferential intervals around the neck finish.

Abstract: The invention relates to a clutch of the kind comprising a coupling element (33) which acts like a piston, and a clutch plate coupled with the coupling element to permit the latter to be driven in rotation. In order to drive the coupling element (33) positively in rotation in both directions, the clutch plate (35) has in combination two groups of tongue or strip portions (48T, 48R), which extend in opposite circumferential directions and which are associated in the sense that each strip portion of one group is paired with a strip portion of the other group, a strip portion (48T) of the first group being continuous with a strip portion (48R) of the second group.

A passageway is provided in the disc for receiving the spacers. The passageway consists of an aperture which is formed partly in an inner periphery of disc and in an outer periphery of the damper plate.

Abstract: A vane assembly for an abrasive blasting wheel wherein the vanes are provided with sidewalls flaring away from the heel of the vane at an angle in the range of 2 to 7 degrees to effect oven distribution of abrasive transverse of the vane face at a varying operating rate.

Abstract: This relates to an elevating system for elevating used abrasive particles in a blast machine arrangement so that theused abrasive particles may be returned to an associated blast head for reuse. Basically speaking, the abrasive particle elevating system includes a throwing wheel mounted within a housing to which there is coupled an elevating casing. These two elements replace the normal and more expensive installation a bucket type conveyor for delivering the used abrasive particles and materials removed thereby to an elevated separator associated with a supply bin for abrasive particles for an elevated blast head. The throwing wheel may be of a varied construction and there may be at least two throwing wheels in tandem to provide for a greater elevating height or horizontal distance. If desired, a second throwing wheel may throw the used abrasive particles over the roof of a blast room so that there may be a blast head on two opposite walls of the blast room.

Abstract: A surface cleaner wherein abrasive particles are directed against a surface to be cleaned, after which the abrasive particles rebound into the cleaner and return for recirculation. Several features are involved. First there is provided an accelerator for the normally gravity flowing abrasive particles to accelerate the particles towards a throwing wheel wherein the abrasive particles are spread over a greater depth of an associated throwing vane. Some of the abrasive particles will not rebound entirely up into the machine for return to the abrasive particle supply chamber. Accordingly, there is provided a separate path for the weaker rebounding abrasive particles to return to the accelerator. The throwing wheel includes a tubular hub into which one of the supporting bearings for the associated shaft is telescoped. This permits throwing wheels of different widths to be utilized. The vanes of the throwing wheel are flat vanes having at their inner ends enlargements.

Abstract: A dispenser for wiring accessories has an elongate plate-like configuration and comprises a baseplate from which projects a bar extending transversely across the baseplate to a width less than the width of the baseplate. A longitudinal groove in the bar parallel to the baseplate runs the full length of the bar. A lip faces the longitudinal edge of the bar into which the groove opens. The lip is parallel to and spaced from this longitudinal edge. The baseplate is extended at one end of the bar. A transverse cradle on this extension receives a wiring accessory and a longitudinal finger projects cantilever-fashion from the bar over the cradle and is spaced from the cradle to retain a wiring accessory in the cradle.

Abstract: This relates to a closure combination which includes the closure being formed with a sealant channel to which there is applied by spin lining a plastisol type compound sealant, or the like. It is preferred, from an economy standpoint, to utilize a minimal amount of the sealant while providing the necessary sealing surface between a container neck finish and the sealant. Since the sealant is applied by a spin lining process during which the closure is rapidly rotated, the sealant is thrown radially outwardly by centrifugal force. However, the viscosity of the sealant normally is such as to prevent it from being returned to a level-flat condition. It has been found that by modifying the sealant channel configuration, particularly the slope of the base wall thereof, depending upon the viscosity of the sealant, one can selectively obtain a uniform thickness sealant application or a flat top sealant application.

Abstract: In a multi-cylinder engine, equipped with at least two induction valves per cylinder, with one of said valves having a narrower induction and crossing stroke, and with another of said at least two valves having a wider induction and crossing stroke, and with a choke valve per each cylinder, the invention provides for a fuel injector to be installed substantially in correspondence of the induction valve having the narrower induction stroke and crossing.

Abstract: A silencer for the exhaust gas of motor vehicle internal combustion engines is proposed comprising an outer wall having in its upper part a deformable zone, preferably in the form of a transverse indentation, which provides preferential deformation under impact, and if a rear impact occurs prevents the silencer from rigidly striking the most inner structure of the vehicle floor and the fuel tank.

Abstract: This relates to an improved container tamper evident bead and neck finish arrangement which provides improved tamper evident band breakage upon removal of an associated closure. Most specifically, beneath the customary retaining bead, a container neck finish is of corrugated or scalloped configuration and is of a size whereby the tamper evident band or a retaining bead thereof is stretched across the space defined by a groove between two adjacent ribs so as to provide for a degree of interlock between the stretched tamper band and the container neck finish such that the tamper evident band is restrained against rotation with the remainder of the closure when the closure is rotated to effect removal thereof. This provides for a much quicker and more reliable breaking of the webs joining the tamper evident band to the closure skirt.

Abstract: This relates to a container, particularly adapted for receiving a hot-fill product. Most particularly, the container is a blow molded plastic container with the principal plastic material being a polyester resin. Critical areas of the container have walls of a laminated construction with preferably at least five layers of which two layers is a moisture barrier layer. The polyester resin primarily utilized, PET, is very sensitive to moisture pickup and by utilizing the moisture barrier layers, the moisture pickup of the primary resin may be reduced with a resultant reduction in the shrinkage and distortion of such container when hot filled.

Abstract: An ophthalmic lens centering and mounting device includes a base which receives and centers the ophthalmic lens. A support receives a holding and securing device for the lens in a removable way and is carried by an arm mounted to swing on the base to apply the holding and securing device to the ophthalmic lens. A barrel mounted to rotate on the arm carries the support. A template support carried by the barrel receives in a removable way a template that has to be superposed on the lens before the holding and securing device is placed on the lens.

Abstract: This relates to the mounting of a sealing head for sealing a plastic lid in a plastic container by way of induction heating.
