Abstract: ABSTRACT In a flow regulator there is a diaphragm (9) between an inlet pressure chamber (17) and an outlet pressure chamber (18). The outlet pressure chamber (18) is bounded by a dished abutment wall (12) in which there is provided at least one radial groove (14) connected at the radially outer end to the inlet side. The central region (20) of the diaphragm (9) is biassed by a spring (21). This permits the characteristic curve of the regulator to be set over a larger range and more accurately than hitherto.         Fig. 1

Abstract: A by-pass channels in a double-acting mechanical pump for an atomizer of liquids, where a radial channel in the wall of a minor cylinder is placed outside a sealing piston and is connected, if the sealing piston is in its upper dead center, with a spraying nozzle and a space above an operation piston by means of longitudinal slots. This causes a reverse section of a residual liquid after completion of each operation cycle, so that the nozzle does not become clogged. Therefore also fast-draying liquids may be sprayed.

Abstract: Improved Liquid Delivery Apparatus and Method for Liquid Fuel Burners and Liquid Atomizers Abstract An improved apparatus and method for delivering liquid are disclosed for use in fuel burners or atomizers of the type which comprise a hollow atomizer bulb having a smooth, preferably convex exterior surface which tapers toward a small aperture through which high pressure air or gas is forced to atomize liquid as it flows in a thin film over the exterior surface of the bulb.  To provide thinner films at the aperture when lower atomization rates are desired and thicker films when higher atomization rates are desired, a feed tube for the liquid is positioned above the atomizer bulb with the discharge opening of the feed tube oriented so that the vertical distance from the front edge of the feed tube to the convex surface of the atomizer bulb is from 1.5 to 2.0 times the vertical distance of the rear edge of the feed tube to the surface of the atomizer bulb.  With the feed tube positioned in this manner, the stream of liquid issuing from the discharge opening preferentially deflects toward the rear of the atomizer bulb at low flow rates and toward the front of the atomizer bulb at higher flow rates, thereby permitting a greater range of adjustment between the highest and lowest atomizing rates achievable.

Abstract: ABSTRACT    This invention relates to improvements in TRIPODS and more particularly to tripod connections.    The invention includes a link portion which links tripod leg portions either formed as legs for ground contact or as portions for engaging with legs for ground contact so as to enable the legs to be arranged into a tripod like configuration, converging toward one another and inter-connected together adjacent an upper portion thereof.   The tripod can be in the form of shear  legs, scaffolding supports, ladders and the like.    The tripod connection includes a link portion having one portion thereof pivotally connected in a captive manner with a first leg portion and second and third leg portion engaged also with the link portion and able to be positioned substantially remotely of the connection of the link and first leg portion on a curve portion whereby said link portion can be pivoted to a substantially "over centre" position with a portion of said link portion remote from the pivot connection with said first leg portion bearing against said first leg portion with the second and third leg portions extending outwardly to provide the tripod like configuration, the assembly substantially securely mounted in that position.     At least the second and third leg portions are axially moveable relative to their connection with the link portion to engage on curved portions which assist in orientating said leg portions in the splay condition in use.

Abstract: ABSTRACT OF THE DISCLOSURE   A stacker-retriever lift carriage is disposed to be raised, lowered and positioned, in selected positions with respect to a pair of spaced support masts, by a flexible wire cable one end of which is connected to a lift carriage drive and the other end of which is connected to the lift carriage through a pair of four bar linkages pivotally connected together in spaced parallel relationship to form a safety brake operating mechanism. The upward pull by the cable upon the brake operating mechanism retracts a pair of opposed brake arms, pivotally carried by the brake operating mechanism, to a brake deactivated position with the back ends of each brake arm abutting each other. Loss of the pull of the cable on the lift carriage, as would occur if the cable severed or if the lift carriage hung up, permits a spring housed between the brake arms to move the brake operating mechanism and the brake arms to a braking position with brake pads carried by the brake arms in friction engagement with the support masts.

Abstract: METHOD OF FABRICATING HIGH BIREFRINGENCE FIBERS            ABSTRACT        The present invention relates to a technique for producing polarization preserving and single polarization optical fibers.  As disclosed, high birefringence is introduced into the preform by deforming the fiber preform such that a cladding layer becomes flat and highly conformable, while the core remains hard and substantially round.  In particular, a cladding layer with a relatively low melting point is utilized such that when the preform is heated the cladding becomes liquified while the core remains solid.  The preform may then be deformed so that the cladding layer is substantially flattened.  Standard drawing techniques may then be utilized to form polarization-preserving fibers and single polarization fibers from the preform.
