Abstract: The present invention is generally related to a new construction for a resistor-type anode. Sacrificial anodes are used in a variety of applications to protect metallic structures from corrosion. In order to control the rate of consumption of the sacrificial anode, a resistor is placed in series between the anode and the tank (cathode). This invention relates to an improved resistor anode construction for use in a tank, for example a hot water tank. The anode includes a core wire with a spring welded to the exposed end. The spring is biased against a disc shaped resistor. The assembly is retained by a metal cap swaged over an insulating sleeve fitted on the end of the anode.

Abstract: A gearshift lever assembly provides vibration isolation between the gearshift lever and its associated housing and additionally provides elastic restoring forces in opposition to movement of the gearshift lever into one of its shift positions. In the preferred embodiment the gearshift lever is supported by a member made from elastic material which surrounds the gearshift lever and is assembled with permanent pretensioning in a direction opposite to the movement of the lever into one of its shift positions.

Abstract: A riser cover is fixed to a shaft which is rotated in bearing projections of a bearing member which is attached to a riser. Impact transmitted to the bearing member upon opening of the cover is absorbed and damped before it is transmitted to the riser. Shock absorbing elements, preferably in the form of plate springs, are positioned between the bearing member and a supporting device of the riser.

Abstract: A washer-type spring, commonly called a Belleville spring, which has an improved fatigue life and residual compressive stresses resulting from the creation of a carbon gradient through the spring thickness. This improved spring is formed from a plain carbon or low alloy steel which, after blanking, cutting and forming, is heated to a temperature above the austenitizing temperature in a carbon-rich atmosphere, held at this temperature until suitably carburized, and then quenched.

Abstract: The present disclosure relates to a method and means for preloading bearings and more particularly the preloading of tapered roller bearings of the type used in the axle systems of motor vehicles. In accordance with the disclosure a pair of Belleville spring washers are positioned against one of the races of a tapered roller bearing and secured in position in a manner so that the springs exert the desired preload upon the bearing. A self curing synthetic plastic material is injected into the housing containing the spring washers so as to surround the washers whereby the preload on the bearing will be set and will not be altered by subsequent high bearing loads on the spring washers. The surrounding plastic material prevents significant subsequent compression of the spring washers beyond their initial compression.

Abstract: A disk spring also known as a Belleville spring is used for applications where stiffness of the spring is an essential requirement and where the usual disk springs made of metal cannot be used or are impractical to use. The disk spring of the invention consists of a body having the shape of a conical shell of elastically deformable material, such as plastic resin, and reinforcing elements within the shell to establish directed resistance to specific deformations occurring in the disk spring when axially loaded.In preferred embodiments of the invention, the reinforcing elements have the shape of bodies of rotation designed and positioned within the shell in configurations chosen to satisfy specific requirements of particular practical applications. The stiffness, the spring constant and the load carrying capacity which can be achieved are considerably higher than are obtainable with customary glass fiber reinforced plastic disk springs.

Abstract: A device suitable for weighing tablets, during manufacture, comprises a ring whose deflection is proportioned to a normal stress applied to it. The deflection may be measured by a suitable transducer, such as a linear differential transformer. Sideways flexing of the ring is prevented by cantilevers connected to the ring perpendicular to its plane.

Abstract: This invention relates to a diaphragm spring serving as a clutch spring for applying engaging force to the clutch, in which a shot-peened layer is provided only on a concave rear surface of said diaphragm spring, especially only on a surface of the pressure plate side of a peripheral annulus which is subjected to tensile stress in engaging the clutch. According to this invention, an early decrease (yielding) in spring force of said diaphragm spring can be avoided.

Abstract: A synchronous device for changing speed gears in a motor vehicle includes a slotted, springy, synchronous ring which is affectable by servo action and formed with at least one groove extending along at least a portion of the inner circumference of the ring.

Abstract: A washer-type spring, commonly called a Belleville spring, which has an improved fatigue life and residual compressive stresses resulting from the creation of a carbon gradient through the spring thickness. This improved spring is formed from a plain carbon or low alloy steel which, after blanking, cutting and forming, is heated to a temperature above the austenitizing temperature in a carbon-rich atmosphere, held at this temperature until suitably carburized, and then quenched.

Abstract: An improved rate controlling fulcrum surface for use with a Belleville spring having a cone height of the unslotted spring portion of about 1.7 to about 2.3 times the spring thickness. The fulcrum has a convex surface on which one face of the spring moves as a load is applied to the spring. The fulcrum is ring shaped and has a relatively wide convex face, the movement of the face of said spring on said fulcrum acting to modify the inherent rate variation in the Belleville spring to provide a greatly extended range of a substantially constant spring load or maintain a substantially linear rate of spring deflection during use.

Abstract: A special-purpose spring retaining ring adapted to be sprung into a circumferential groove provided therefor in a shaft, post, housing and the like, thereupon to form an artificial shoulder thereon, comprising: an open-ended ring body provided by circumferentially spaced-apart middle and sidewardly disposed (wing) arcuate length-portions having section heights which decrease progressively from the mid-section of the middle arcuate length-portion to the open gap-defining ends of the ring body, spaced-apart upright queen-truss formations interposed between and connecting the opposite ends of said middle arcuate length-portion to the adjacently disposed ends of said sidewardly disposed arcuate length-portions, the open ends of said ring body being shaped as outwardly extending formations, the outer edge of the beams of said truss formations and the outer edges of said ring-end formations extending as arcs of one and the same circle struck from the center of the ring body.
