Each bracket leg portion has a plurality of longitudinally spaced openings and tabs for receiving the hoops of the band at selective positions along its length. Each bracket is adjustably connected to the band for circumferential positioning at selective locations on the band to axially align the apertures of the upstanding base portions with an existing mounting arrangement of the support surface.

Abstract: A liquid level valve control system includes pressure responsive means compring a first chamber containing a first diaphragm having a port for applying pressure; bleed means enabling air to pass this diaphragm; and passageway means enabling air then to pass into a further chamber also containing a diaphragm operatively linked to the valve operating apparatus; so that, when a predetermined and substantially constant pressure is applied at the port, air bleeds past the first diaphragm into the further chamber to move the diaphragm therein to activate the valve control system, but when a surge of pressure is applied at the port the first diaphragm moves to block the passageway into the further chamber, thus preventing pressure being applied to the latter's diaphragm to activate the valve control system.

Abstract: A magnetically detectable plastic, e.g., polyethylene, polyvinyl, etc., pipe for underground use comprises a hollow tubular plastic pipe having particles of magnetic material embedded in plastic and secured integrally with the wall of the pipe. The magnetic particles are of iron oxide or barium ferrite and of a size, shape, distribution and proportion such that the plastic pipe may be easily detected by magnetic detection apparatus on the surface when the plastic pipe is buried at a selected depth under the ground. The magnetic particles are uniformly distributed throughout the thickness and uniformly distributed around the entire circumference of the plastic pipe or the magnetic particles may be distributed in discrete portions of the plastic pipe, as for example, a uniform outer layer of the pipe or in stripes or strips extending along the pipe.

Abstract: A hypodermic needle has a retractable tubular sheath slidably mounted on its forward end and movable relative thereto between a rearward retracted position exposing the front end of the needle and a forward protective position enclosing the front end of the needle. In one embodiment, a spring within the sheath urges the sheath to the forward protective position enclosing the front end of the needle. The rear of the sheath cooperates with pins on the needle to engage them upon relative rotation in one direction to allow rotation as a single unit to connect the needle to fluid ejection or withdrawal members. Relative rotation in the opposite direction disengages the pins allowing the sheath to be moved rearward causing the front end of the needle to protrude beyond the front end of the sheath and to lock the needle and sheath together upon further relative rotation in the opposite direction to disconnect and dispose of the needle without inadvertent injury by contact with the needle.

Abstract: An artist's easel comprises a framework adapted to receive and hold a canvas, and one or more wheels mounted on the framework and enabling the easel to be wheeled to and from a place of use. The easel also includes means for maintaining the frame in its normally intended attitude of use, and means which, in use, engage the ground on which the easel stands to resist any tendency of the easel to move along the ground. The easel is characterised by two features. Firstly, that the said ground engaging means comprises one or more feet which project at a fixed angle from the lower portion of the frame; and secondly, that the or each wheel is mounted on the fram via a linkage which is so constructed that a user of the easel can move the wheel (or wheels) away from the foot (or feet) to stand the easel on the ground so that the wheels and the or each foot engage the ground in spaced-apart relationship to maintain the frame in its intended attitude of use.

Abstract: An intravenous catheter has an elongate small diameter flexible tubular front portion and a rear base portion which has an interior bore in communication with the interior of the tubular portion for connection to a needle or other fluid injection or withdrawal members. A thin flexible membrane seal formed of resilient stretchable material is secured over the opening at the rear of the catheter base. The elasticity of the membrane seal allows the beveled front end of a needle to be pushed through the membrane and puncture the seal as it passes through and will not tear, but will stretch as the forward motion of the needle continues and conform to the profile of front portion of the needle base and allow it to engage the interior of the catheter base. The needle may be inserted into the catheter in the usual manner and the needle and catheter may be used just as any standard catheter-needle assembly.

Abstract: A method for conversion of comminuted cellulosic agricultural wastes into a form edible by ruminant animals comprises treating such wastes, e.g., straw, corn husks, cotton wastes, peanut shells, saw dust, etc. by spraying with an aqueous solution of a mixed oxidant gas, at a pH of about 11-12, to produce a water content of less than 40% and a pH of about 11.4-11.7 in the waste. The mixed-oxidant gas is preferably produced by a gas generator comprising an electrolytic cell having an anode compartment, a cathode compartment and a membrane separating the compartments to permit only a limited flow of electrolyte therebetween. When a low salt concentration solution is electrolyzed in this cell, the output is a mixed oxidant gas containing chlorine and various oxygen-containing species. Another gas generator which may be used is that shown in U.S. Pat. No. 4,248,681. The oxidant gas produced from dilute salt solutions contains chlorine, chlorine dioxide and other oxygen-containing gases.
