A vehicle with a hydraulic system including an engine with a hydraulic pump with at least one driven wheel which incorporates a separate driving mechanism having a hydraulic motor in communication with the hydraulic pump. This motor includes a housing with pistons which are cycled by hydraulic pressure applied through a switching arrangement which periodically opens pressure and return ducts as the wheel turns. A cam plate associated with the wheel shaft allows sensing rollers to move control el...

This invention relates to the catalytic decomposition of hydrazine, catalysts useful for this decomposition and other reactions, and to reactions in hydrogen atmospheres generally using carbon-containing catalysts.

Thyristors are produced starting with an N-type wafer and forming P-type layers on opposite sides to act as the anodes and gates of the thyristors. N-type layers acting as the cathodes are then produced in or on the plate layers, after which the wafer is coated with nickel and then with gold, and gold is removed from at least part of the portion of each gate-cathode junction which is exposed in the surface of the wafer. The wafer is then divided into chips by cracking or sawing, and the cracked ...

A clip for currency or papers is formed of two leaves hinged together near one end having finger grip portions beyond the hinge in one direction and paper grips in the opposite direction. The leaves may be made in various shapes and emblems, logos, monograms etc. may be formed integrally with or applied to the leaves. Associated with the hinge is a resilient means for biasing the paper grip portions together. Such means may be a torsion spring imbedded in the hinge eyes, a leaf spring having opp...

A branch shroud for containment conduitry in which shroud halves are brought together with seals at their abutting edges. The abutting edges have interleaved retention devices that receive pins to hold, and perhaps to force, the edges toward each other.

An effective radon ventilator which adapts to laundry dryer vents. The unit vents radon gas from houses at the point of greatest concentration, the basement or ground level, as well as venting other objectionable fumes. The ventilator houses a fan and a flow damper to vent both airborne radon gas/fumes and laundry dryer vapors. A heat transfer device enables energy efficient operation.

Proteinaceous material is added to beer or other beverages. In beer and those other beverages on which a head can be formed it helps to improve the head, while in beverages not normally forming a head it can enable a head to be formed. Proteins extracted from albumen may be employed or whole albumen may be used. To avoid any tendency to haze-formation, particularly on pasteurization, protein fragments may be used. These can be formed by hydrolyzing proteins such as albumen proteins. An alternati...

Fiberballs for filling uses have been prepared from mechanically-crimped fibers having both a primary crimp and a secondary crimp with specific configurations, especially amplitudes and frequencies. The fiberballs may contain a proportion of other fibers, particularly binder fibers.

A printing apparatus has an array of cartridges for printing a web of e.g. paper passing through the array, and one or more units containing printing medium. The cartridges each are capable of transferring the printing medium from the unit(s) to the web. The unit(s) and the cartridges of the array are relatively movable, to allow the unit(s) to interact successively with at least two of the cartridges. In this way it is possible to change printing from one cartridge to another, allowing changes ...

A door for hangars and other structures in which the door is made in a plurality of sections with each section being comprised of slidably mounted panels guided in fixed and movable guide structures. The movable guide structures are mounted intermediate the length of the door and include telescopic parts which move with the panels to clear the door opening when the panels are elevated. The panels and movable guide structures are stored in the head frame of a door opening of any desired configura...
