Assignee:

Bowles Fluidics Corporation - Columbia MD

International Classification:

F16B 710

US Classification:

403 52

Abstract:

A joint comprising a body member defining an annular groove and a pair of tangential notches intersecting the annular groove at diametrically opposed positions. A socket member is comprised of a preferably semispherically shaped frame having an open side and a pair of diametrically opposed knob or pin member. Each knob or pin member is engagable with one of the tangential notches to snap fit the body member within the semispherically shaped frame and within the annular groove. The body member is secured to a mounting bar and the semispherically shaped frame has an elongated slot and the mounting bar passes through the slot. The arrangement is such that the slot defines one path of rotation of the shaped frame member relative to the body member and the annular groove defines a second path of relative rotation between the body member and the shaped frame. Cooperating friction surfaces are formed on the frame and body members to control resistance to movement and maintain the members in their positions of adjustment.

International Classification:

A61K 3119

US Classification:

514557

Abstract:

The invention is a method of modulating or controlling autoimmune disease in a host. The method includes the step of administering to the diseased host a pharmaceutical effective amount of succinylacetone. The pharmaceutically effective amount of succinylacetone is desirably infused by an osmotic minipump in order to modulate the effects of autoimmune disease in the host.

International Classification:

B05B 108
F15C 108

US Classification:

2395891

Abstract:

A fluidic oscillator comprises a housing having interior walls defining a cylindrical space therein, a fluidic oscillator is mounted in said cylindrical space and has an oscillating chamber having an upstream end and a downstream end. A power nozzle issues a jet of fluid into the oscillation chamber from the upstream end thereof, an outlet formed in the downstream end. A pair of control ports at opposing sides of the power nozzle are coupled to a pair of feedback entranceways in the downstream end of the oscillator chamber and at corresponding opposing sides of the outlet. The control passageways connect each feedback entranceway with the a control port on the opposing sides, respectively. Each control passageway is formed in part by the interior wall and the oscillator element.

US Classification:

2392841

Abstract:

A windshield washer system has a nozzle mounted on a vehicle for issuing wash fluid to a windshield and a check valve for a fluid circuit from a supply of wash fluid to the nozzle. The nozzle has a fluid feed tube integrally formed therewith with annular walls defining a washer fluid flow path and a diameter of at least D. The feed tube has an external surface adapted to receive and retain a flexible hose from a supply of wash fluid. A spring shoulder receives a coil compression spring having upstream and downstream ends with the downstream end bearing on the spring shoulder. A valve element bears on the upstream end of the spring element, and a tubular insert having an inner end and an external diameter at least D and sufficient to form an elongated wash fluid seal with the annular walls defining a washer fluid flow path, and complementary-shaped valve seat formed on the inner end.
