Abstract: At least one component of a spindle assembly has matched bosses disposed to the opposite sides of a transversely extending, axially offset coupling recess or key, for balance of the forces acting therealong.

Abstract: Sensors are incorporated into a multiple spindle automatic screw machine in such manner as to effectively monitor burring spindle retraction and stock supply and feeding. The lubricant/coolant level sensor is housed in a protective auxiliary chamber, and adaptations to the threading axis drive, the work spindle axis drive, and the cam axis drive improve performance of the machine while at the same time reducing its complexity.

Abstract: A multiple-spindle mechanism employs an arrangement of passages, grooves, and ducts that promotes continuous and simultaneous lubrication of all spindles. The mechanism is especially well suited for use in an automatic screw machine.

Abstract: A collet-operating mechanism utilizes an array of wedge members for the transmission of closing force to the pressure collar. The wedge members are of flatted barrel-shaped configuration to optimally cooperate, in line contact relationships, with bearing surfaces on the pressure collar and the supporting sleeve member.

Abstract: A system for washing parts utilizing a circulated, heated liquid includes a master unit and at least one auxiliary unit. The master unit has a tank for heating the washing liquid, and has a pump for circulating the liquid through the chamber of the enclosure. The auxiliary unit is devoid of such a tank, but has means for making connections necessary to enable circulation of the liquid heated in the tank of the master unit through the chamber of the auxiliary unit enclosure.

Abstract: A collet-operating mechanism utilizes an array of wedge members for the transmission of closing force to the pressure collar. The wedge members are uniquely configured to optimally cooperate with a convexly arcuate bearing surface on the supporting sleeve member, to effect closure with greater facility and to produce an increased level of force amplification. In addition, the wedge members are of such form as to make feasible manufacture by conventional machining operations.

Abstract: An assembly of a highchair having a smooth seat, and a thin, flat, compliant pad freely covering the seat surface. The pad is made from one piece of solid, rubbery material providing a high coefficeint of friction, and it has a matrix of apertures formed through it, each defined by a sharp peripheral edge at its juncture with the faces of the pad. The pad conforms to the seat in an anti-slip relationship, and it provides good mechanical interengagement with the diaper or garment of a baby seated upon it, despite the lightness of the baby's body.
