Abstract: INTERCHANGEABLE HYPODERMIC NEEDLE ASSEMBLAGE               ABSTRACT OF THE DISCLOSURE   An interchangeable needle assemblage for a hypodermic syringe which enables needles of varying lengths and characteris-tics to be readily attached to the barrel of an existing syringe or vial.  The barrel has an opening with a sealing membrane disposed thereacross, adapted to be pierced by the inner end of the needle.  Carried on the barrel is a locking type ferrule having a pair of internal locking shoulders located on opposite sides of a slot.  A needle hub assembly is receivable in the slot, being rigidly affixed to the needle at a point intermediate the ends thereof, said assembly having finger-engageable ears to facilitate grasping of the hub, and further having shoulders cooperable with the locking shoulders on the ferrule. To install a needle on the syringe or vial, the hub is first inserted into the ferrule so that the hub shoulders by-pass the internal locking shoulders of the ferrule.  The hub is then turned to cause engagement between the said cooperable shoulders, thus securing the needle in place.  During insertion of the needle and hub into the ferrule, the inner end of the needle pierces the sealing membrane and communicates with the interior of the syringe barrel or vial, thus readying the item for use.

Abstract: ABSTRACT OF THE DISCLOSURE      An angular positional sensor comprises a housing in which is mounted rotary sensing device including a shaft which mounts a pendulum having relatively low inertia and a balance member having relatively high inertia and rotatably mounted within the housing adjacent the pendulum member. At least the part of the housing containing the pendulum and the balanced member also contains a liquid to provide a viscous coupling between the pendulum and the balanced member. The arrangement is such, that in use, angular movement of the housing about the longitudinal axis of the shaft causes movement of the rotary sensing device relative to the shaft which is retained stationary by the pendulum which in turn is damped by the balanced member, to produce a signal representative of such angular movement from the rotary sensing device.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for and method of employing a high per-centage of reground polyethylene resin scrap in an extruder, wherein fluffy, low-density, polyethylene scrap resin is preferably admixed with a granular high-density polyethylene virgin resin, and the admixture fed by gravity into a first feed inlet in a screw-type conveyor, and granular polyethylene virgin resin fed by gravity into a second feed inlet generally adjacent to and downstream of the first feed inlet of the extruder.  The admixture fed to the first feed inlet is in-sufficient to fill the volume of the extruder tube, while the virgin resin automatically fed by gravity fills up the total volume in the extruder tube, thereby preventing starvation of the resin to the extruder die in the event of blockage of the fluffy scrap resin, which technique permits high amounts of from 20 to 40% of scrap resin to be blended with virgin resin.

Abstract: SOLID STATE DUAL TIMER            ABSTRACT OF THE DISCLOSURE            A solid state electronic dual timer which, in one preferred embodiment, is utilized for dispensing a measured quantity of lubricant at predetermined time intervals.  A contin-uously operating pump is selectively connected to the devices requiring lubricant by a control valve means.  A capacitor is charged through a first circuit path from one predetermined level until it reaches a second predetermined level during which time the control valve means for dispensing the lubricant is energized.          As soon as a second predetermined level is achieved, the pump means is deenergized, at which time the capacitor is caused to discharge towards said first predetermined level at a slow rate.    The charging rate is typically adjustable over a range between 2-90 seconds in charging from said first to said second predeter-mined level and is further adjustable over a range which is typically of the order of a few minutes to several hours when discharging from said second to said first predetermined level so as to dispense lubricant during a period of from 2-90 seconds every two hours, for example, said interval being repeated on a cyclic basis.

Abstract: Case 2521 ABSTRACT OF THE DISCLOSURE      A circuit and a method for preventing the discharge of current from a charge storage device when a power failure occurs are disclosed. The charge storage device (e.g. capacitor) is effectively isolated from the rest of the circuitry by the use of electronic switches.  These electronic switches are powered by an auxiliary power supply (independent of the main power supply) and are controlled by a voltage sensitive switch that turns the switches "off" as soon as the voltage magnitude of the main power supply drops below a predetermined minimum level.  By so doing, the possible discharge paths for the charge storage devices (capacitors) are eliminated, and the capacitors retain the charge they had at the beginning of the power failure (except, of course, for any interval leakage).

Abstract: ABSTRACT OF THE INVENTION       A mattress construction and method of making is disclosed in which an extremely wide, deep stitch flange permits a more uniform and tighter mattress construction.  A mattress cover is sewn to an apron or flanging material with a wide border or flange with the thread being deeply set in the cover by the thick foam padding between the flange material and the cover.  This construc-tion allows the apron to be very tightly pulled over a coil spring and stapled  through sisal padding to the coil spring rim or border.          The stretching of the flange skirt and cover creates a bow in the coil spring pulling the rim toward the center.  The wide flange then permits the skirt or side cover to be tightly stitched with edging tape or binding material to produce a very firm and flat mattress construction.
