Abstract: A syringe includes a body for receiving a medicament and a plunger movably connected to the syringe body. The plunger is moved with respect to the syringe body to draw in and dispense the medicament. A plurality of dose setting indicators are disposed on the plunger. The plunger is rotated outwardly from the syringe body to draw medicament into the syringe body. The plunger can be pushed or rotated into the syringe body to dispense the medicament.

Abstract: A universal cuff for a blood pressure monitor that has a usable length that is variable so that it can be used on a wide range of arm circumferences. The universal cuff includes a mechanism for setting the usable length having a shutoff cam and a D-ring. A blood pressure monitor is also presented having a mechanism for determining the usable length of the cuff by measuring inflation rate or by controlling a deflation rate control valve during deflation.

Abstract: A medication delivery pen is provided having a reusable pen body assembly and a disposable cartridge assembly that are threadedly engageable with one another. The disposable cartridge assembly includes a plunger and can releasably receive a needle cannula assembly. A portion of the pen body assembly projects into the cartridge holder assembly for driving the cartridge plunger distances that are selected in accordance with a desired dose of medication to be delivered. The cartridge holder assembly can be disassembled from the pen body assembly after the medication therein has been exhausted, and the used cartridge holder assembly may be discarded and replaced.

Abstract: An apparatus is provided for safely and conveniently holding and dispensing needle assemblies. The apparatus includes a generally tubular holder with opposed dispensing and inserting ends and an elongate passageway extending therebetween. The tubular holder is dimensioned to slidably receive needle assemblies therein in axial alignment with one another. Separator disks are disposed between adjacent needle assemblies in the holder, and an end disk is disposed between the inserting end of the holder and the needle assembly adjacent thereto. The separator disks and the end disk are color coded to be readily visible through a window in the holder. The needle assembly nearest the dispensing end can be mounted to medication delivery pen or other hypodermic syringe and may be removed from the holder. The used needle assembly may then be inserted into the inserting end of the holder. This process is repeated for each administration of medication until the supply of needles is exhausted.

Abstract: A device and method for filling a conventional disposable plastic syringe with a mixture of insulins. The mixing device includes a pair of disposable cartridge assemblies each containing a different type of medication to be mixed in the syringe and a pair of medication dispensing mechanisms for dispensing the medication out of a respective cartridge. Each dispensing mechanism permits one to specify the dose of medication to be dispensed and drives a plunger into its respective cartridge a specific distance based on the specified dose. The mixing device also includes a syringe holder assembly that holds a syringe until a mixed dose of medication must be dispensed and provides proper alignment of the cannula of the syringe with each cartridge assembly during mixing.

Abstract: The invention relates to attachments to the anticavitation plate of a boat motor for making and controlling small variations in boat speed below the normal motor idling speed to facilitate trolling for fish. The trolling speed control includes an incrementally adjustable unitary plate mounted for movement between a position fully across the normal paths of the propeller wash, thereby to slow the speed of the boat and to a fully retracted position out of the path of the propeller wash. This invention relates to motorboat low speed control devices.

Abstract: Method and apparatus for making phase stable measurements of charateristics of microwave antennas and other devices utilizing an optical transmission path as a phase stable reference in order to identify phase errors along a radio frequency transmission path induced by flexing of a radio frequency transmitting cable as the antenna probe or antenna under test is moved in the course of testing. Similar apparatus and techniques are described for use with a harmonic mixer to gather receiver data which is free of phase errors caused by movement of the antenna.

Abstract: An RF MESFET amplifier having a feedback resistor further incorporates two sets of quarter wavelength low impedance pads and quarter wavelength high impedance lines in the resistor feedback path. These RF impedance elements prevent RF feedback as well as thermal noise generated by the feedback resistor from being coupled to the input. Moreover, they effectively isolate RF interaction between the drain and gate of the MESFET; as a result, the amplifier has excellent stability. The low impedance quarter wavelength pads serve as an RF bypass (to ground), while the high impedance quarter wavelength lines provide high attenuation near frequencies at the given wavelength. Consequently, thermal noise generated by the feedback resistor will be bypassed to ground and will not leak into the gate. The value of the feedback resistor can be selected and optimized to obtain the desired VSWR, bandwidth and gain flatness.

Abstract: A system is disclosed for using internally generated electricity as the power to OPERATE an electrolysis cell for the production of hydrogen gas. This hydrogen gas would be stored under pressure and used on demand as a fuel supplement as for hill ascension by a diesel locomotive.
