Abstract: REMOVABLE PLASTIC CONNECTOR     ABSTRACT OF THE DISCLOSURE          A connector for connecting one type of windshield wiper arm end to a cross pin-type wiper blade.  The arm end is releasably attached to the connector which connector has a body portion with a pin-receiving slot on the forward end thereof.  The orientation of the pin-receiving slot with respect to the longitudinal axis of the body portion is such that to assemble the arm to the pin on the blade, the axis of the arm and connector relative to the longitudinal axis of the blade approaches 75° to 90°.  The pin-receiving slot is forced over the pin on the blade to seat the pin in the slot.  Once the pin on the blade is in the slot in the con-nector, the arm is pivoted relative to the blade until the axis of the arm is substantially parallel to the axis of the blade.  The width of the connector is such as to contact the walls of the opening in the blade to guide the arm relative to the blade and at the same time the body portion of the con-nector fits into said opening in the blade and has a shoulder to prevent the connector from becoming disengaged from the blade during normal use of the blade.

Abstract: ABSTRACT OF THE DISCLOSURE     A plurality of narrow ballast tanks arranged around the periphery of diaphragms such as those disclosed in the inventor's U.S.          Patent No. 4,117,796 "Double Sectioned Tank".  The peripheral ballast tanks facilitate the construction, installation, operation, and maintenance of the diaphragms that segregate the cargo oil from the ballast water in the oil tanker in which they are fitted, and allow the tanker in which they are fitted to carry substantially more cargo than an identical externally dimensioned standard segregated ballast tanker.         The peripheral ballast tanks, which are located in the lower portion of the cargo tanks, in general are built along the longitudinal and transverse bulkheads and ship's sides, but they can also be arranged to sub-divide the lower portion of large cargo tanks, they, in effect, form a tank grid about the lower portion of the cargo tanks space, with the cells in the grid being suitable for the reception of the diaphragms.         The diaphragms each consist of three main parts:         (a)  a vertically movable thin and flat partition, that can, if required, be buoyant in order that it may float on ballast water;         (b)  a mating but fixed partition rim fitted outside of the movable partition, as described below;  (c)  an elastomeric membrane sheet that is fitted between and attached to the movable partition in such a manner that the complete diaphragm forms an impervious barrier to oil or water attempting to pass from top to bottom or vice versa.          Movable partition guide and securing means are also provided.         By locating the fixed partition rim at mid-point of the movable partition travel on the sides of the peripheral ballast tanks, major savings of membrane material can be achieved.  Compensatory steelwork can be built into the peripheral ballast tanks to replace material and structural strength lost due to steelwork removed to make room for the installation and operation of the segregating diaphragm.         The peripheral tanks on the tanker's side, if of the required width, will be "protective ballast space" when the tanker is in the cargo loaded condition, as will the double bottom space beneath the diaphragm, if it is of suitable height.

Abstract: ABSTRACT OF THE DISCLOSURE      A tunable optical fiber reflector is described, together with a method of making the same.  A length of optical fiber has a core of a first light transmitting material, and a cladding of a second light trans-mitting material covering the core.  The cladding is etched away to a pre-determined thickness over a portion of the fiber.  A layer of photoresist material is applied either to the etched away portion of the fiber or to a thin metal blade, i.e., mask, and then exposed to beams of light which optically interfere and generate a standing wave pattern in said material. The photoresist material is then developed to fix said wave pattern therein. An optical discontinuity is formed in one of the core and cladding by that fixed wave pattern, said discontinuity representing a quasi-periodical fluc-tuation in the refractive index and causing evanescent waves in the cladding to be reflected.  Such discontinuity forms a distributed-feedback reflector. In one method, the fiber core in the etched portion is bombarded under a vacuum with a beam of ions passed through openings having said standing wave pattern, thus producing quasi-periodical fluctuations in the refractive index of the core.  More preferably, the photoresist material is coated on the etched portion of the fiber, and counter-propagating light beams are coupled into opposite ends of the fiber.  These beams expose the photoresist material and generate the standing wave pattern therein as residual quantities of the same.  The etched portion of fiber is typically filled with reinforcing material such as an epoxy.  Two such reflectors in an optical fiber make up a resonator, and several resonators can be used in a hydrophone line-array.

Abstract: ABSTRACT OF THE DISCLOSURE     A fuel regulator receives fuel from a fuel pump at essentially constant pressure and reduces the pressure of the fuel to a constant low value in response to a predetermined high to moderate vacuum in an inlet manifold of an internal combustion engine, the vacuum corresponding to low or moderate load.  At high load the regulator supplies fuel at a pressure proportional to absolute manifold pressure.  At low to moderate loads the fuel at low pressure passes into the float bowl of a carburetor when a float controlled needle valve opens in response to a low level of fuel in the bowl as fuel is burned in the engine.  The low pressure does not unseat the needle valve and supply an excess of fuel to the bowl.  At high loads, the fuel pressure to the bowl is adequate to supply the increase rate of fuel such loads demand.  As a result, the engine operates lean at low to moderate loads and richer at high loads.  The regulator has a first diaphragm controlled valve.  A second diaphragm controlled by manifold vacuum opens the valve at high absolute manifold pressure.  At a range of low to moderate absolute manifold pressures, the first diaphragm maintains the valve open effectively the same amount regardless of manifold pressure within the range.  The valve only closes when the load suddenly drops from a high load and prevents engine loading.

Abstract: BALL VALVE AND SEAT ASSEMBLY                  (Abstract of the Disclosure) A ball valve having an improved relationship between the ball and associated seat rings and an improved seat ring design for such valves.  The ball is mounted for selective rotation and limited axial movement in a valve body passageway.  Seat rings disposed on diametrically opposite sides of the ball about valve inlet and outlet openings each include a first ball engaging surface.  A frusto-conical disc spring mounted between each seat ring and an associated valve body shoulder urge the seat rings into engagement with the ball.  A reinforcing ring disposed at the forward end of each seat ring acts as a rigid bearing surface.  Component sizing is such that in the assembled valve, the seat rings are slightly rotatably flexed outwardly of each other in response to the first surfaces thereof engaging the ball.  At the same time, the disc springs are partially compressed while continuously urging the seat ring first surfaces into ball engagement.  When the valve is closed under fluid pressure conditions, the ball is shifted downstream causing the downstream seat ring to be further rotatably flexed in the direction of ball movement.          The upstream seat ring is simultaneously rotatably flexed in the same direction under the influence of its disc spring.  At typical fluid operating pressures, the downstream disc spring is fully compressed to a generally flattened condition and the ball is shifted away from all contact by the upstream seat ring.  In this condition, the upstream reinforcing ring prevents upstream seat ring displacement and also prevents seat ring distortion when the valve is reopened.  A groove may be advantageously included in the seat ring rear faces to accommodate ease of rotational flexure.
