Abstract: ABSTRACT An intravenous set has a volume limiting chamber for precisely controlling the volume of parenteral solution admin-istered to a patient and a flexible drip chamber for determin-ing the parenteral solution flow rate.  The volume limiting chamber has a membrane valve which when wet will pass parenteral solution but will not pass air at normal intravenous administra-tion pressures.  An air bypass is provided in the volume limit-ing chamber so that air can bypass the membrane valve and enter the volume limiting chamber from the drip chamber when the drip chamber is squeezed to prime the intravenous set.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to and discloses a novel resistor composition and a process for manufacturing the composition.  The composition comprises a conductive material, a glass frit and a vehicle therefor, or a conductive material, a glass frit, an insulating or semiconductive metal oxide and a vehicle therefor.  The weight ratio of the conductive material, the glass frit and the metal oxide (when the latter is present) is maintained substantially constant.  The resistance value of the composition is established by varying the total surface area of the conductive material and the glass frit and when applicable, the metal oxide, without changing the temperature coefficient of resistance of the composition.  The resistor has an excellent, definite and easily obtainable temperature coefficient of resistance whereas in the prior art, it had been impossible to obtain certain definite resistance values without varying the temperature coefficient of resistance.

Abstract: Abstract of the Disclosure A magneto-alternator has a plurality of alter-nator coils for lighting or the like and a main ignition coil for a breaker-point ignition.  Stator laminations are arranged so that the ignition coil is between two alternator coils and each coil is effectively on an E-shaped core with an outer leg of each E-shaped core being shared with an adjacent coil.  The flywheel has a plurality of ceramic magnets having a high potential energy so that a high alternator output is developed.  The center core leg of the E core on which the ignition coil is mounted has a large air gap relative to the air gaps at the other core legs to compensate for the high energy of the magnets and thereby limit current at the breaker points.  The large air gap also makes the magneto output insensitive to production tolerances in the air gap.

Abstract: Abstract of the Disclosure A constant velocity universal joint comprises an outer joint element having grooves on its spherical inner surface.  An inner joint element is positioned within the outer joint element and is provided with grooves on its spherical outer surface to form pairs of opposed grooves with the grooves on the outer joint element.  A ball is positioned in every pair of opposed grooves and a cage disposed between the two joint elements retains the balls in a plane perpendicular to the axis of the cage.  The cage is guided within the outer joint element by a spherical surface on the outer face of the cage and is guided with respect to the inner joint element by a spherical surface on the inner face of the cage.  To facilitate assembly in the joint without weakening structural strength of the cage, the cage is provided with transverse notches or grooves in two diagonal positions.  Each groove is formed at a ball aperture and has a width and a depth so as to be capable of receiving a ridge between adjacent grooves on the outer joint element.

Abstract: ABSTRACT OF THE DISCLOSURE                A coin slide apparatus which includes a housing for mounting the apparatus to a machine, a coin slide assembly, and a guideway in the housing for the coin slide assembly to operate within. The coin slide assembly is reciprocally operable in the guideway from an extended coin receiving position through coin measuring and coin ejection positions to a position for initiating operation of the machine. The movable slide assembly comprises three main members: an upper slide plate, a center body portion, and a latch plate. The upper slide plate is formed to include the operating handle at one end and has coin receiving slots of a predetermined size. The center body portion gives the slide assembly the necessary thickness to support coins on edge, serves as a storage area for blanking members which are used to convert the apparatus from one combination of coins to another, and mounts a ratchet pawl which prevents the slide from being withdrawn with-out a complete reciprocation. The latch plate mates with latch arms, which are mounted on the housing, to prevent operation either without coins or with spurious coins. The coin slide apparatus also includes various devices for measuring coins and a coin ejection system for removing coins from the slide assembly and depositing them in a receptacle.

Abstract: ABSTRACT OF THE DISCLOSURE       The disclosure relates to a viewer for a stereoscopic filmstrip having a plurality of spaced perforations along one longitudinal margin and including a series of pairs of left and right hand stereoscopic frames.  The viewer includes a casing for receiving the filmstrip and the casing includes a front wall, a rear wall, and a top wall.  A pair of lenses are mounted in positions spaced transversely of the front wall for use in viewing the filmstrip.  Film masking means are disposed inside the casing at a position spaced from and generally parallel to said front wall. The masking means defines a pair of apertures positioned to permit viewing of the respective left and right hand frames of successive frame pairs as the filmstrip is advanced through the viewer in use.  Means are provided for guiding the filmstrip in a path which extends trans-versely of the casing rearwardly of the masking means. The viewer also includes a film transport mechanism disposed inside the casing and positioned laterally of said apertures in the masking means.  The transport mechanism includes a film-engaging disc which is turnable about an axis normal to the direction of filmstrip movement and which has a peripheral series of teeth for engagement in said perforations in the filmstrip  so that turning of the disc advances the filmstrip past said apertures.  A drive member is pro-vided for turning the disc and is itself turnable about an axis parallel to the turning axis of the disc.  The drive member includes an operating lever which projects to the exterior of the casing for turning the member and which is movable from a rest position to a fully advanced position.  The drive member is biassed to normally maintain the operating lever in said rest position.  Ratchet means couple the drive member and disc so that movement of the operating lever from said rest position to said fully advanced position causes the disc to turn and advance the filmstrip uni-directionally by an amount equal to the spacing between successive pairs of films on said filmstrip.  Detent means cooperate with said disc for preventing return movement of the disc in a direction counter to the film advance direction upon release of the operating lever.  The viewer also includes means for illuminating the filmstrip.  The illuminating means are defined by at least one light admitting aperture in the top wall of the casing, the aperture being positioned rearwardly of said masking means.  Reflector means are arranged in an angular position at the rear of the film path for reflecting incoming light through the apertures in the masking means to illuminate the filmstrip.

Abstract: Abstract of the Disclosure A battery preferably for use as a power source in an electrical vehicle includes  a plurality of envelope separators for reducing the concentration of waste products at the surface of the battery plates.  The envelope separators comprise two thin sheets of microporous material which are bonded together at their edges and placed between each of the plates of the battery.  The envelope separators while being nonconductive are highly porous thereby allowing electrical current to pass from one plate to the other through the separators in the electrolytic solution of the battery.  The electrolyte is pumped into each envelope separator under pressure and is forced out through the pores or small holes in the sides of the envelope to flush water, gas and loose particles of active material away from the plates of the battery.  By forcing the electrolyte against the plates of the battery, the concentration or specific gravity of the electro-lyte at the surface of the plates is increased, thereby increasing battery efficiency.

Further circuitry produces and is responsive to an oscillating signal subject to line impedances to distinguish between an open circuit and an excessive impedance.
