Abstract: A connector secured to a panel and connectable to a circuit terminal. The connector extends through a panel opening with a flange abutting the panel rear and a front portion with a connecting terminal projecting from the panel front. A lock washer around the connector front portion includes a planar washer body and integral lock tabs radially outward of its central aperture. A securing tab extends radially from the washer body and is bent away from the panel front face. A nut is secured to the connector outer thread over the lock washer. A protective cover is selectively securable over the connector front portion by threading on the connector outer thread, and a lanyard secures the protective cover to the lock washer securing tab.

Abstract: A lock washer includes a planar washer body formed of a sheet of resilient metal having a selected thickness no less than the pitch thread of the bolt with which it is to be used. First and second lock tabs integral with the body extend radially outward of the central aperture, wherein each of the tabs has a radially inward facing, straight, free edge transverse to a radius of the body, and each of the tabs is displaced by a spring bend to one side of the plane of the body. The washer body is etched to a selected lesser thickness in the area of the spring bend to provide a selected spring force when the tab is pushed down to the plane of the body.

Abstract: The valved container assembly comprises a container positionable on an adjustable stand. The container incorporates an outlet tube adjacent the bottom of the container, the outlet tube incorporating an inline flow control valve and an end valve which stops flow through the tube when flow into a receptacle for fluid from the container reaches a height below overflow.

Abstract: The valved container assembly comprises a container having a combined inlet/outlet incorporating an inlet valve, an outlet tube positionable over the inlet, the outlet tube incorporating an inline flow control valve and an end valve which stops flow through the tube when flow into a receptacle for fluid from the container reaches a height below overflow, the assembly allowing no vapor escape during filling or emptying of the container.

Abstract: The marine bumper comprises a body including two oppositely extending wings which are centrally engaged to a base in a manner to be rotatable relative thereto, such that the wings may be horizontally or vertically oriented. Also, the bumper is adapted for engagement to a cleat of a boat by an extension arm, if such mounting, rather than dock mounting, is desired.

Abstract: The retaining strap comprises a thin, elongate piece of expandable and non marring material having a plurality of spaced apart longitudinal slots therein to which objects, via retainers, can be engaged. The retaining strap also has terminal connectors thereon for securing the strap to itself and/or other objects to be engaged thereby.

Abstract: An assortment of lock washers is produced from a method including the steps of (a) providing a plurality of blanks formed of generally planar resilient metal, some of the blanks having a different configuration from other of the blanks, each of the blanks including a central aperture, an outer periphery, a tab, and two locating holes spaced from the central aperture and spaced from each other a selected distance and at a selected orientation relative to the tab; (b) providing a tool having two locator pins and structure for bending a tab out of the plane of a blank; (c) orientating the two locating pins with the two locating holes of a selected blank; (d) actuating the tool to bend the tab of the selected blank out of the plane of the selected blank; and (e) repeating steps (c)-(d) for each of the blanks.

Abstract: Corrosion, loosening, safety and reusability problems incurred with prior art lock washers are eliminated in a lock washer having a planar washer body (6) formed of a thin sheet of resilient metal. A central aperture (12) is located in the body (6) and is adapted to receive the shank (24) of a bolt which a nut (22) is to be attached and locked. A lock fold (8) is formed in the body (6) radially outward of the central aperture (12). The lock fold (8) has a radially inward facing curved edge (18) displaced to one side of the plane of the body (6). The edge (18) is transverse to the radius of the body (6) and a lock fold (8) resiliently, lockingly engages with a flat of the nut.

Abstract: A programmable switch includes a housing. A sensor is associated with the housing. The sensor senses a measurable physical property of a sensed element proximate the housing and developing an electrical signal varying relative thereto to represent the sensed physical property. A logic circuit is disposed in the housing and receives the electrical signal. The logic circuit includes a memory for storing a reference value and a controller for comparing the reference value to the sensed physical property to determine status of the sensed physical property. An input circuit is operatively associated with the logic circuit for selectively changing the stored reference value to reprogram the switch. An output switch is operatively associated with the logic circuit to externally indicate status of the sensed property.

Abstract: Corrosion, loosening and reusability problems incurred with prior art lock washers are eliminated in a lock washer having a planar washer body (10) formed of a thin sheet of resilient metal. A central aperture (18) is locate in the body (10) and is adapted to receive the shank (42) of a bolt to which a nut (40) is to be attached and locked. First and second lock tabs (14), (16) are formed in the body (10) radially outward of the central aperture (18) and are the sole lock tabs on the body (10). Each of the tabs (14), (16), has a radially inwardly facing, straight free edge (30) displaced to one side of the plane of the body (10). Each of the edges (30) is transverse to a radius of the body (10) and the lock tabs (14), (16) are angularly spaced by more than 90.degree. and less than 180.degree. such that when one free edge 30 is engaging the flat (50) of a nut (40), the other free edge (30) will be underlying a point (52) of the nut (40), between two adjacent flats (50) thereof.

Abstract: A switch actuator includes a base and a plunger mounted for movement on the base. An electrical contact is mounted for relative movement on the base to establish an electrical connection. An actuator includes a head portion and a pair of spring arms. The spring arms extend into a bore in the plunger for frictionally grasping the plunger by spring biased forces against the interior walls of the bore. The actuator has a head portion exposed from an open end of the plunger bore for effecting movement of the electrical contact to alter the state of the electrical connection. The frictional engagement between the spring arms and the plunger provide overtravel or relative movement therebetween and the affect of the spring arms substantially eliminates any affect from wear between the plunger and the actuator.

Abstract: A switch actuator includes a base and a plunger mounted for movement on the base. An electrical contact is mounted for relative movement on the base to establish an electrical connection. An actuator assembly is mounted for movement on the base and is operatively associated with the plunger for effecting movement of the electrical contact to alter the state of the electrical connection. The actuator includes a pair of relatively movable members with a wedge member therebetween. The wedge member is effective to cause conjoint movement of the movable members and to allow relative overtravel movement between the members. The relationship between the electrical contact and the actuator assembly is adjustable to vary the movement differential of the switch actuator.
