An electrical storage battery is constructed with anode and cathode plates arranged in a radial configuration within a cylindrical case. The plates are supported within a rack which maintains a proper radial alignment. The radial arrangement of the flat plates enhances the stability of current and voltage during discharge as contrasted with prior devices.

By providing a pillow having a central head supporting portion with two extension portions, substantially perpendicular to the central portion, an extremely comfortable, restful, sleeper-encircling pillow incorporating built-in arm rests and blanket or sheet slip-prevention means is achieved. In the preferred embodiment, the pillow comprises a substantially uniform cross-sectional area throughout its entire length, with easily accessible, firm, supportive filler material disposed within an enclo...

A multiple sectioned agricultural implement having hydraulically powered folding means. A fixed center section and each side having inner wing sections and outer wing sections, each set respectively indentical in structure. Hydraulically powered folding cylinders fold the outer wings over and alongside the inner wings. A hydraulically powered lift cylinder means plumbed in parallel with the fold cylinders lifts the inner wing sections and their respective folded outer wing section to a vertical ...

A fuselage configuration for aircraft flying at high subsonic speeds is constructed of a first portion defined by a portion of the surface of a respective three-dimensional, spindle-shaped geometrical construction, the major axis of which is large relative to the minor axis, and a second portion defined by a portion of the surface of a respective three-dimensional, spindle-shaped geometrical construction, the major axis of which is also large relative to the minor axis. The two portions are arra...

Punch configuration in which the geometry of the face involves planar surfaces which angle inwardly on opposed edges of the punch face. The angled planar surfaces terminate on a straight line and are interconnected by a grooved circular surface. As designed the punch configuration is symmetrical and the angles of the planar surfaces as well as the radius of the grooved cylindrical surface are calculated to require the least amount of punch force.

A motorcycle has an engine with a crankcase supported on a body frame. The body frame has a pair of rear arm members. A battery is supported on the body frame between the rear arm members in the vicinity of the back of the crankcase, thereby being disposed in a convenient and compact lower region, and leaving an enlarged upper region available for articles such as an air cleaner, whose size should not unnecessarily be limited.

This disclosure is a hub which includes a resilient means designed to engage the shank of a needle, cannula or stylet and resist axial movement therebetween while holding same therein. The configuration of the hub allows the axial relationship between the needle, cannula or stylet and the hub to be set and maintained during further assembly operations. Disclosed also is a method for assembling the needle, cannula or stylet to the specifically configured hub.

An airfoil having two (2) basic components, a sail and spoiler, associated with the leading edge of the sail, is herein disclosed. This unique airfoil design has application in flexible wing aircraft (i.e., ultralites), sport parachutes and sport kites. In the typical sport kite embodiment of this invention, there will generally be at least three (3) aerodynamic flight control surfaces: a sail, a keel, and a flexible resilient spoiler attached to the leading edge of the sail. The sail material i...

An exhaust configuration for a gasoline engine where the exhaust gas is merged with an air stream in a direction counter to the direction of flow of the air stream for reducing noise and for supercharging the engine and for reducing the amount of oil that may become entrained in the exhaust stream.

In order to improve a waveguide configuration for high-frequency-excited, diffusion-cooled gas laser system comprising a waveguide carrier with a cavity closed like a ring in an azimuthal direction in relation to a longitudinal axis and extending in the direction of said longitudinal axis, and a waveguide for guidance of a laser beam along an optical axis, the waveguide being arranged in the cavity and formed by waveguide wall surfaces disposed at a constant spacing from one another, the width o...
