A linear actuator is a hybrid in that movement of the armature is influenced by the field of permanent magnets and the field of a coil when it is energized by direct current. The coil is fixed in a ferromagnetic shell and a pair of permanent magnets are fixed in the shell axially of the coil. The armature has a reduced diameter tip or end which is influenced by the magnets when the coil is deenerg...

Between 0.001 and 0.5% by weight of polytetrafluoroethylene powder is incorporated in the composite electrochemically active mass carried on the lead plates of a lead-acid storage battery. In the case of the positive electrodes, the result is to lengthen the service life in terms of cycles of charging and discharging. In the case of the negative electrodes, the effect is to raise the low-current y...

A multiple source, rotating, tomographic x-ray scanner includes x-ray sources adaptably configurable to operate in two modes. The first mode of operation, in which the sources are planarly configured, permits high speed, single slice scans to be made. The second mode of operation in which the x-ray sources are configured so as to scan distinct, but contiguous planes, permits multiple slices to be ...

A belt-drive infinitely variable transmission is connected to a crankshaft of an engine through an electromagnetic powder clutch (1). The current to the clutch coil (8) is controlled by a control system (41) having an engine speed signal producing circuit (48, 49), a vehicle speed signal producing circuit (52, 53) and an arithmetic circuit (50) which controls the clutch current flowing through the...

There is provided an article for use by persons lying on the ground at the sea or like locations. The device serves as a head rest for the reposing person and as a sun shade. When not in use as stated, the device serves as a carrying bag.

Under normal skiing conditions, two lateral arms of a jaw unit cooperate with the toe end of a ski boot in order to maintain the boot in the axis of the ski and are held in position with a force designated as the inherent stiffness of release. When an excessive twisting effort is exerted on the skier's leg, the arms both move in a transverse direction with respect to the ski in order to permit lat...

Polyesters are combined with UV-stabilizing substances in order to produce an end product, such as a film, sheet, ribbon or filament, by mixing polyester granules and the UV-stabilizing substance in powdered form at an elevated temperature such that at least the exterior surface of the polyester granules is soft, thereby to cause the powdered UV-stabilizing substance to adhere to the individual po...
