Hook means for fastening a chain-bound article securely in connected position, access to the throat of the hook being gained through a slotted entry of diameter sufficiently greater than the diameter of the bar stock of the chain with which said hook is used to permit clearance of a link of such chain through said slotted entry, and thus permit rapid connection and disconnection thereof while minimizing the possibility of accidental disengagement of said hook and said chain.

An electrolytic capacitor is described having an anchoring spike between the capacitor body and the capacitor seal which stabalizes the capacitor body from movement with respect to the capacitor container and also provides adequate space for gas expansion in the device. A thermally conductive medium such as tar or asphalt material is preferably used in the bottom of the container to provide additional anti-vibration stabalization and thermal conductivity for removing heat from the capacitor body...

Liquid household bleach composition containing optical brighteners protectively carried in the bleach solution against chemical deterioration by a finely particulate sequentially prepared synthetic organic polymer which is dispersed through the bleach solution.

A humidifier comprising a container having a bowl-shaped lower portion. Integral with the lower portion is an upper wall which slants upwardly and inwardly and terminates in a top having a main opening for receiving a vapor-producing head. A Baffle is integral with the upper wall and is spaced between an outlet opening and the main opening. A fill opening having a conical downwardly and inwardly tapering wall extending below the outlet opening is provided at a location diametrically opposite the...

A tool or tool holder having a shank which is received in the socket of a machine tool spindle or other tool carrier. A resilient bumper ring is fitted on the rear end of the shank to protect both the shank and the socket from damage. In one embodiment of the invention the bumper also serves as a wiper to clean the socket.

The skeleton frame of a building consists essentially of identical frame elements fastened to each other to form a system of parallelepiped-shaped cells, each cell being bounded by four frame elements which are at least in part common to two contiguously juxtaposed cells. The cells may be freely cantilevered from upright pillars or freely span distances between pillars which are multiples of the horizontal dimension of one cell.

A turbopump having an inducer and a two stage centrifugal pump has hydrogen entering an inducer and passing through a first stage impeller and a second stage stage impeller to the exit thereof. A turbine is located on the opposite side of said impellers from the inducer and has an integral shaft extending through the impellers and inducer on which they are mounted. A front radial bearing means is positioned between the inducer and first impeller and a thrust balancer means and rear radial bearin...

An aircraft has a fuselage from which wings and horizontal stabilizers extend. At low speeds the lifting forces exerted by the airstream passing over the wings create a moment about the center of gravity for the aircraft, and that moment is offset by an opposite or trim force exerted on the horizontal stabilizers. At higher speeds the resultant of the lifting forces on the wings shifts rearwardly and thereby increases the moment about the center of gravity. At such speeds auxiliary airfoils exte...

A watch movement operating regular time indicators and two totalizers mounted coaxially to the center of the watch capable of being returned to a zero position.

A gyroscope in which the rotor is supported with respect to its driving shaft by a plurality of intermediate gimbals in which each intermediate gimbal is torsionally attached to the rotor and to the driving shaft, the attachments being positioned, the spring constants being adjusted, and the moments of inertia of the gimbals being adjusted to allow the rotor to be a free rotor while eliminating rectification torques, caused by oscillatory inputs on the shaft, from the rotor.
