Abstract: Suspension strut comprising a cylinder and a spring perch which is axially displaceable relative to the cylinder for adjustment of the position, wherein the spring perch has a sleeve portion by which the connection to the cylinder is carried out. A chamber is arranged on the cylinder side which is at least partly filled with a moldable material. The sleeve portion contacts the moldable material, which in a solid state transmits a supporting force from the cylinder to the spring perch.

Abstract: A suspension strut including a piston rod extending from a cylinder, a connection bearing for connecting the piston rod to a vehicle body, a spring loading the cylinder away from the connection bearing, and a spring plate supporting the spring axially with respect to the connection bearing. A first bearing enables relative rotational movement between the spring plate and the connection bearing, and a second bearing enables relative rotational movement between the connection bearing and a stop buffer arranged between the connection bearing and the cylinder.

Abstract: A machine and a process of using the machine for turn-broaching a workpiece to for crankshafts or camshafts. The machine comprises turn-broaching units having peripheral cutters whose cutting surfaces are monitored and automatically adjusted to compensate for wearing. The angular positions of the cutters of a turn-broaching unit may also be offset with respect to one another such that only one cutter is in contact with the surface of the workpiece at each instant.

Abstract: A freeze resistant first stage pressure regulator for use with a high pressure source of breathable gas includes a housing and a yoke, for attaching said housing to a high pressure source of breathable gas along with a pressure regulated outlet, a valve seat and a piston. A spring is provided for biasing the piston in order to effect a regulated valve opening between the piston and the valve seat and provide a pressure regulated supply of breathable gas to the pressure regulated outlet. The spring, piston and valve seat are all sealed within the housing. An antifreeze liquid is sealed within the housing for excluding contact of said spring and piston with ambient water; and a pressure transfer device, disposed in a wall of the housing and in fluid communication with the antifreeze liquid is provided for equalizing pressure between the ambient water and said antifreeze liquid.

Abstract: A first stage pressure regulator for use with a high pressure source of breathable gas includes a housing and means for attaching the housing to a high pressure source of breathable gas. A pressure regulated outlet is provided and a valve seat member fixed within the housing includes a central seating surface perpendicularly disposed to a longitudinal axis of the valve seat member. The perimeter of the valve seat member is shaped to enable the breathable gas to pass parallel to the valve seat member longitudinal axis in order to enable the high pressure source to be connected coaxially with the first stage pressure regulator. A piston is provided which includes a hollow center in fluid communication with the pressure regulated outlet. An open end of the piston is provided for sealing the piston against the central seating surface of the valve seat, and a spring is provided for biasing the piston in order to effect a regulated valve opening between the piston open end and the valve seat member.

Abstract: A first stage pressure regulator for use with a high pressure source of breathable gas includes a housing and either a yoke arrangement for connection to the conventional U.S. high pressure gas source or a DIN connection for coupling to a European-type gas source. First and second presure-regulated outlets are provided and independently regulated in order to provide from a single high pressure source dual intermediate pressure air for delivery to second stage regulators. In combination with second stage regulators, a system is provided which has enhanced safety features.

Abstract: A second stage scuba regulator is provided which includes inlet for receiving a supply of compressed air and a piston valve in communication with the inlet for causing air flow through the regulator when the piston valve is opened. A lever is provided for opening and closing of the piston valve, and an air volume controller is provided, which is independently operable from the lever for varying the amount of air flow through the regulator when the piston valve is opened by the lever.

Abstract: A method for internally cleaning a powder-carrying hose conduit of an electrostatic powder coating system between changes in powder color. A granule/air stream is conducted through the hose to be cleaned, and the granules are returned for re-use after they emerge from the hose.

Abstract: A system for spraying a coolant mist onto a part being machined, and including a container for holding a quantity of coolant liquid and having a distribution head to which the coolant liquid and compressed air or other gas to be used as a propellant are delivered separately, and from which the liquid and gas flow into a plurality of discharge hoses having separate nozzles for spraying the coolant onto a plurality of different work pieces. The distribution head preferably includes a centerpost into which the coolant and propellant gas flow, and a manifold body extending about the centerpost and having a plurality of outlets communicating with the different discharge hoses at different circularly spaced locations.
