Abstract: BLOW MOLDING MACHINE ABSTRACT OF THE DISCLOSURE          This relates to a blow molding machine of the type for blow molding large articles such as containers of the one gallon to five gallon size from a parison in the form of an extruded plastic material tube.  The machine is of the rotary type and has a plurality of stations each carrying a mold unit of which one half is fixed and the other is mounted for radial movement between open and closed positions.  The main shaft of the machine is of a large diameter and is tubular so that the necessary manifolding for gas and coolant supplies may be readily incorporated in the main shaft in an entirely different manner from that heretofore utilized.  Also, among other features of the machine, is the provision of hollow spokes which serve not only to support outer mold halves for radial movement, but also serve as manifold accumulators for the necessary operat-ing gases.  There is also a new cushioning pad arrangement which holds the mold halves together under a light initial pressure facilitating the latching of the molds to a closed position with a minimum of camming force, after which the necessary pressure may be applied against the movable mold half so as to compensate for the opening pressures developed within the mold during the blow molding operation.                     * * * ,* * * * *

Abstract: FLEXIBLE TUBULAR JOINT                          ABSTRACT        The joint may be used in a diving suit.  It includes a plurality of annular members connected by respective piston and cylinder portions which together define an oil chamber.  Oil flows from a pressurized make-up system into one end of the serial chain of chambers, the flow between adjacent chambers being controlled by respective valves.  Respective valves open on axial compression of the joint, due to hydro-static pressure, when the volume of oil in any of the chambers is below a design value   Respective valves are closed when their associated chambers contain the predetermined volume.  This accommodates for any shortage of oil due to inadequate filling or compression of air bubbles, or loss due to lubrication.  The coupl-ing between adjacent connecting members may include a spherical surface to enable relative tilting in any direction, as well as relative rotation.  A gimbal mounting is provided for each valve in a respective one of the connecting members, the gimbal mounting being slidably anchored in an adjacent connecting member.  The gimbal mounting preserves the flexibility of the joint without impeding the valve action.  It also prevents pull-out of adjacent piston and cylinder portions when there is a tendency for the joint to expand axially, as in the case where a diving suit is brought to the surface.  In order to facilitate the fitting of the piston portion to the cylinder portion having spherical surfaces, respective leading circular rims of annular walls of the piston and cylinder portions are stepped or staggered with respect to one another.  An arrangement is also disclosed to ensure that the furthest oil chambers in the serial chain receive an adequate supply of oil.  According to this arrangement, the joint is structured so that the oil pressure is progressively slightly different in the serial chain of oil chambers, the oil pressure being highest in the chamber at the body end (i.e. of the divers body) and lowest in the chamber at the outer end of a limb.

Abstract: POWER-DRIVEN SCREWDRIVER  WITH A TORQUE CONTROL     ABSTRACT OF THE DISCLOSURE       A screw tightening apparatus comprises a motor-driven screwdriver bit supported on a base for tightening a screw with a torque which is detected as a reactive force acting on the base by a torque detector.  An output signal from the torque detector is amplified and delivered to a comparator in which the signal is compared with a signal from a torque setting device which is indicative of a desired torque with which the screw is to be tightened.  When the signals agree with each other in the comparator, the latter produces an output signal which is supplied to a switch which in turnde-energizes an electric or pneumatic motor of the screw tightening apparatus.  An adjustable time-delay circuit is connected between the comparator and the switch to delay the signal from the comparator for a period of time which may be varied dependent on the material into which the screw is to be driven and the pitch and material of the screw in use. The screwdriver bit is coupled to an output shaft of the motor through an electromagnetic clutch which is de-energizable by the switch simultaneously with the de-energization of the motor.
