Abstract: A burner nozzle assembly is disclosed for atomizing liquid fuel at lower emission velocities, and comprises an axially extended nozzle body and a nozzle cap mounted forwardly thereon, the nozzle cap and nozzle body cooperating to define a flow reversing fluid path for the liquid fuel, to cause the fuel to move essentially countercurrent to its initial direction of flow, and to the flow of an auxiliary fluid disposed in an outer coaxial conduit. The reversal of flow of the liquid fuel, promotes a collision between it and the auxiliary fluid, to facilitate thorough atomization, without the need for increase in emission velocities, that results in higher fuel consumption and reduced per capita fuel utilization and heat radiation. The nozzle is adapted to operate in a variety of burner assemblies, including conventional burner guns, and is of simple construction.

Abstract: A locking assembly is disclosed which is suitable for releasably locking two articulated pivoting members in a fixed position with respect to each other. The locking assembly comprises a spring biased reciprocating latch, a plunger attached to the latch, and a catch plate adapted to rotate into locking engagement therewith. The plunger and latch are preferably integral with each other, so that the latch contains a minimum number of moving parts. The latch is designed so that simple palm pressure will cause it to disengage from the catch plate, to permit the pivoting members to move with respect to each other. The present locking assembly is of simple design and inexpensive manufacture, and is durable in use. The locking assembly is particularly applicable for use in invalid appliances such as collapsible walkers, where the users have limited manual dexterity.

According to the invention, each self-locking nut is formed with two engaging grooves extending in directions perpendicular to each optical axis adjusting rod. One of the grooves has two opposite surfaces formed with round extensions extending toward each other. The other groove has a bottom having a convex along its generatrix.

Abstract: A depthometer useful for underwater diving is constructed with a cup-shaped casing, and a rotatable transparent cover that is sealably snap-mounted to the casing and closes the front of the casing. The transparent cover houses an indicating pointer that rotates about an axis of the casing as a function of external pressure, and moves along the scale of a stationary dial. The indicating pointer cooperates with a maximum-indicating pointer by way of a dragging member that communicates with both pointers. The dragging member is idly supported by an axially bored member which extends through the cover. The axially bored member cooperates with an adjustable friction clutch and thereby also serves to support the maximum-indicating pointer. The construction of the present depthometer permits the cover to be snap-mounted to the casing without adversely affecting the water-tightness of the instrument.

Abstract: A method and apparatus for shoring a trench.The trench shoring apparatus carries a plurality of sheet members movable vertically relative to said apparatus by driving means forming part of the apparatus which carries pre-formed horizontal waling frame carried by and movable relative to the apparatus.The horizontal waling frame is positionable between the sheet members after the sheet members have been driven by said driving means, so that an upward or downward pressure applied to said waling frame is converted, through the intermediary of said waling frame, into a lateral pressure onto the trench sides, so that the sheet members may be caused to move downwardly or upwardly by increasing the resistance to upward or downward movement of the apparatus. Similarly, a downward pressure applied to means supporting said waling frame, is converted into a lateral pressure, through the intermediary of said waling frame, so as to cause upward movement of said apparatus.

Abstract: A method and associated agents for the arrest of infections resulting from organism growth in contact with an iron-containing body fluid, comprising administering an agent capable of immobilizing the body fluid so that the iron it contains is nutritionally unavailable for the organism. In the instance where the body fluid is blood, the agent may be administered in amounts effective to bind all of the available red blood cells or hemoglobin, to prevent breakdown of either and consequent release of iron to the organism.The agents preferably include materials capable of binding red blood cells and iron, such as haptoglobin, colloidal silica, anion exchange resins and mixtures thereof. Preferably, colloidal silica is used either alone or in a composite with a polyolefin elastomer such as polyisobutylene.The agents may be coated on carriers or substrates, such as gauze pads, tampons and the like, and may be thus utilized topically, as well as intraperitoneally.

Abstract: A wave energy conversion system is disclosed and comprises a spine and a plurality of wave driven pump units each comprising a pillow shaped flexible bag arranged with its length direction horizontal and mounted on the spine so that the water in which the system is located flows to both sides of the bag so that in use the bag is kept out of abrading contact with the spine.

The common passage is at one top corner of the bag and at the other top corner is a dummy passage which enables the bag to be fabricated in such a manner that the corners are not stressed significantly in use. Also, a common pipe can be used to define the common passage of one bag and the dummy passage of the adjacent bag.

Abstract: A method for the continuous, in vivo measurement of glucose concentration in animal body fluids such as blood, comprises implanting in the body, in registry with the system for the body fluid, a glucose monitor adapted to measure the concentration of glucose as a function of changes in such electrical charge. The glucose monitor includes an electrode with an electrical charge-transfer medium comprising a reversible complex of a binding macromolecular component and a charge-bearing carbohydrate component. The electrode includes a selectively permeable membrane permitting the ingress and egress of the body fluid. In operation, glucose present in the body fluid displaces the charge-bearing carbohydrate, which then participates in the electrical activity of the electrode so that a measurable change in electrical activity can be observed when the electrode is connected to an appropriate current-responsive meter.
