Abstract: An ankle exercising device comprising a substantially flat platform and a hemispherical member secured to the bottom surface of the flat platform at its diametric planar surface. The peripheral contour of the platform is preferably configured with respect to the center of the hemispherical member so that the maximum tilt angle of the platform at any peripheral point coincides with the average or normal degree of movement of the biomechanical ankle structure in that direction. At least the top surface of the platform includes indicia so that the foot can be placed in a proper position on the platform, whereby angular movement of the ankle on the device corresponds with the average maximum biomechanical function of the ankle structure.

Abstract: A turbocharger having a main housing with a throughbore through which a tubular bearing carrier is coaxially positioned. A shaft extends through the bearing carrier and is rotatably secured to the bearing carrier by a pair of axially spaced bearing assemblies, each having an inner race, an outer race and bearing elements entrapped therebetween. A pair of spacers are coaxially positioned around the shaft in between the bearing assemblies so that an outer axial end of each spacer abuts against the outer race of each bearing assembly. A helical compression spring in a state of compression urges the spacers axially away from each other to equalize the axial compressive load on each bearing assembly and thereby minimize bearing skidding and uneven wear.

Abstract: The present invention provides a differential pressure monitor having an elongated housing defining an elongated interior chamber. A piston is axially slidably mounted within the chamber and divides the chamber into two subchambers, each of which are fluidly connected to a fluid system. A compression spring resiliently urges the piston in one axial direction in the chamber while an arm abuts against the piston and provides an exteriorly visible signal of the position of the piston within the chamber and thus of the differential pressure between the subchambers.

These strips are constructed of a semiflexible material so that, upon insertion of the strips into the outwardly facing slots, the strips attach the sheet to the vehicle so that the sheet covers the vehicle bed.

Abstract: A sensor group in an automatic temperature control system for foods in vessels heated by a flame from a gas burner supplies a first heat quantity to a temperature sensing element within the group, as a function of the foods' temperature; and a second, smaller heat quantity, as a function of the flame temperature. The ratio between the two heat quantities is such that a small progressive temperature increase is obtained at the sensing element when a constant food temperature has been reached.

Abstract: A device to compensate for the thermic effects of an external source on a sensitive element in a system for automatically controlling the temperature reached by foods in heated vessels. The device includes a conventional range and a potentiometer for controlling a gas or electric heating element. Two heat sensitive elements are employed, one sensing pan temperature, and the other sensing ambient temperature. Electric circuitry automatically adjusts the heating element to reduce the heat output as the ambient temperature rises, so that a more constant vessel temperature is achieved.

Abstract: An anchor comprises an anchor shaft member and an anchor body member in the form of a plate having two blades which are joined to the anchor shaft member by a pivotal connection which allows the blades to lie normally within a range of angles to the plane containing the anchor shaft and the pivot axis. This range of angles is determined by the interconnection between two lugs on the anchor body member projecting away from the pivot axis on the opposite side from the main plate constituting the anchor shaft to enable the anchor to lodge against the submarine obstruction in the usual way: the relative inclination of the anchor body member and the anchor shaft member can be changed by applying a force greater than that required to effect shearing of the shear pin so that the anchor shaft member can swing freely about the pivot with respect to the blade to allow release of the anchor.
