Abstract: Abstract of the Disclosure A fluid flow meter is provided and comprises a housing having a fluid inlet and a fluid outlet and a fluid passage for connecting the inlet with the outlet.  The fluid passage further includes an elongated cylindrical chamber having one end open to the inlet and the other end open to the outlet while a piston is axially slidably mounted within this housing chamber and movable between a first and second position.  The outer periphery of the piston is sealed to the housing.  The piston includes a removable orifice plate having a fluid port open to the inlet end of the chamber while a fluid passage formed through the piston fluidly connects the port with the outlet end of the chamber.  The rod is positioned within the housing and held in place by removable housing and covers.  The rod includes a tapered portion posi-tioned through the port which variably restricts the port in dependence upon the axial position of the piston.  A resilient member urges the piston towards the inlet end of the chamber while an indicator is connected to the piston to provide an exter-iorly visible signal of the axial position of the piston member and thus of the flow through the flow meter.  Further, the piston assembly is constructed as a cartridge assembly so that the top cover can be removed and a new cartridge assembly installed quickly and easily.  A set point is provided so that the new cartridge can be quickly zeroed.   t

Abstract: APPARATUS AND METHODS FOR LINE STRINGING WITH LOAD PICKUP COUPLING DEVICE The problem of stringing power transmission lines via a line-holding structure that has an upper cross support and no side access, such as the center strand under a cross support on a tower, is solved by the methods and stringing apparatus disclosed. The stringing apparatus (40) is carried in a depending manner from the aircraft (10) by a hoist line (54) and enables the insertion of a sock line (30) through the line-holding structure (29), followed by the pulling of the line therethrough. The stringing apparatus is in the form of a needle-type structure, inclusive of a support member (42) carrying front and rear coupling devices (46 and 48) and front and rear tower catches (50 and 52). After the sock line has been strung, one end is secured to a power line which is then threaded through the line-holding structure to complete the stringing of a center strand of power line. A coupling device (515) disclosed includes a pivot member (517) pivotally mounted on the load having a disposition and configuration that is readily engaged by a hoist line (542) with an end or weight member (543) from above and guided into a retainer portion (522) so that as the hoist line is raised a connection is formed between the hoist line and the load. Upon deployment and relief of the weight of the load from the hoist line, the pivot member automatically returns to the starting position and the hoist line and end member are slid therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE A dual cavity hydraulic tire press utilizes a single long stroke piston-cylinder assembly vertically positioned substantially in line with the center of gravity of the vertically movable upper mold sections, the latter being supported on the underside of the outer ends of a shallow V-shaped beam which is mounted for ver-tical movement on a readily removable column or post.  In the closed position of the press the top mold cavities are locked to the base of the press by rotatable bayonet locks. Four short stroke hydraulic clamp piston-cylinder assem-blies are positioned beneath each bottom mold section to achieve clamping pressure during cure.  In one embodiment mechanical stops may be provided to achieve mold height adjustment and to preclude the molds opening significantly upon loss of fluid pressure to the clamping piston-cylinder assemblies.  In another embodiment the clamp-piston-cylinder assemblies are mechanically adjusted to obtain the proper position for mold height adjustment.  The press includes a safety bar which is supported from the top mold section for part of its movement with the bar being held stationary during initial opening movement of the top molds, and then picked up to be in a position just below extended seg-ment molds if employed.  The clamp-piston-cylinder assemblies are provided with extended coolant passages between the clamp actuating fluid and the heat of the mold cavity to preclude degradation of the fluid employed.  The isolation of the clamp pressure at four equally spaced points beneath the bottom platen enables the platens and molds to be more efficiently encased with insulating materials not subject to high pressure during cure.  The position of the clamp-piston-cylinder assemblies as well as the piston-cylinder assembly opening and closing the press preclude hydraulic fluid contamination of the uncured or cured tires passing through the press.  With the present in-vention, a tire curing press of substantially less weight, envelope and energy consumption can be provided.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for manufacturing woven slide fastener stringers comprises means for shedding a plurality of warp threads, a coiling mechanism for coiling a monofilament of synthetic resin around a mandrel in a conical orbit to form a series of coiled coupling elements and a weft inserter reciprocable across the warp shed and the conical orbit for inserting a weft thread into the warp shed, by which the coiled coupling elements can be woven into a stringer tape along a longitudinal edge thereof as the tape is woven of the warp and weft threads.  The weft inserter includes an arm which, when the weft thread is inserted, is engageable with the monofilament to displace the latter out of the path of insertion of the weft thread so that the weft thread can be inserted smoothly without being frictionally engaged by the monofilament.

Abstract: RECLINER CHAIR WITH WALL-AVOIDING ACTION   ABSTRACT OF DISCLOSURE         A handle-operated recliner chair has a seat mount-ing linkage consisting of two mounting links mounting the seat directly to a stationary base for movement between nor-mal and reclining positions.  A footrest is mounted to the front of the seat by a footrest linkage which is extended and retracted through means of a handle mounted relative to the seat to rotate a torque tube which is connected to the foot-rest linkage to operate the same. One of the links of the footrest linkage is directly connected to the front mounting link of the seat such that extension of the footrest will cause the seat mounting links to pivot forwardly to not only place the seat in an inclined position but also, to move the seat forwardly relative to the base to provide wall-avoiding action which comes in to play when the backrest is reclined to avoid striking a nearby wall with the backrest.  The back-rest may be either fixed rigidly to the seat to move together with the seat as a unit to provide a "one-way" recliner or as an alternative, it may be mounted by means of a novel back-rest linkage to the seat to move relative to the seat to pro-vide a "three-way" recliner chair.  In either instance, the backrest linkage is totally independent of the seat mounting linkage and the footrest linkage.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for producing an oxide of sulfur using pressurized air.  The pressurized air is mixed with molten sulfur at a sulfur burner to ignite and combust the molten sulfur and form a reaction mixture.  The molten sulfur may be atomized.  The pressurized air may be divided into two portions, one of which is preheated.  The unheated pressurized air is mixed with the reaction mixture in the sulfur burner downstream of the location where the preheated pressurized air is mixed with the molten sulfur.  Combustion of all the sulfur to sulfur dioxide is essentially completed within the sulfur burner, and the temperature of the gaseous mixture leaving the sulfur burner is controlled.  The sulfur dioxide may then be cooled and converted to sulfur trioxide in a catalytic converter.  The Moisture content of the pressurized air is reduced in a pressurized dryer upstream of the sulfur burner.
