Abstract: A method for using emergency fuel for internal combustion engines which is stable for storage for a year or more. The fuel is a mixture of two fractions of refined mineral spirits, one fraction being aliphatic hydrocarbons, the other fraction being aromatic hydrocarbons. Varying the relative content of the aliphatic and aromatic hydrocarbon mineral spirits provides a fuel with the desired octane number. A biocide is added to the mineral spirits.

Abstract: A special fuel is formulated for use with diesel engines which are used infrequently in emergency situations.

Abstract: A remote recording unit, which is worn by a child, monitors the ambient sounds in a day care center (for example) and records selected sound bytes that are played back on a docking unit. The time duration between sound bytes is periodic and re-programmable. The remote recording unit is "childproof" and tamper-evident to generate an internal "flag" which will be displayed on the docking unit, indicating that the remote recording unit was removed by an unauthorized person. The device is equally applicable to a patient, older person or pet left in the care of a third person or persons or placed in a facility or institution.

Abstract: A retrofitted personal computer ("PC") has an access control module attached to the rear wall of the PC. A secondary switch within the access control module is connected in series between the main switch of the PC and the power supply. An authorized user remotely controls the powering of the PC by turning "ON"-"OFF" of the secondary switch through the "ON"-"OFF" radio pre-coded transmitter. The disk drive of the PC is protected by a disk drive lock, which is interconnected with the access control module and the PC by a cable.

Abstract: A liposome or microsphere containing guaiac or other reagent is used in an immunoassay to detect an antigen or antibody. The guaiac or other reagent reacts with hemoglobin or other blood constituent to produce color indicating a positive result.

Abstract: Eyeglasses are modified to simulate ophthalmologic anomalies which may result from ophthalmic surgery. Various hazed eyeglass lenses are described.

Abstract: A kit for installing a central line in a patient includes a guarded finger scalpel, a needle with a guide wire, and a catheter. The guarded finger scalpel has a blade with a relatively blunt tip, thereby avoiding an accidental or inadvertent cut or nick of the patient's vein in the process of enlarging the puncture in the patient's skin previously made by needle.

Abstract: A locking device (10) is inserted within the disk drive (11) of a personal computer (12) to prevent unauthorized use thereof. The locking device (10) includes a part of pivoted plates (15, 16) retained in their expanded locking position by a key-operated lock (20) carried by the plates (15, 16). Each of the plates (15, 16) carries an arresting mechanism (35) which expands within the disk drive (11), in the event that an attempt is made to remove the locking device (10), and "bites" into the adjacent guide rail (53), thereby stopping any further movement of the locking device (10) out of the disk drive (11).

Abstract: A pharmaceutical composition for treating blepharitis or blepharoconjunctivitis is disclosed for topical administration comprising a nitroimidazole, as metronidazole, in a suitable ophthalmic carrier to be applied directly to affected ocular tissues. The carrier may be an artificial tear solution, an ointment, a water soluble gel, a nonaqueous carrier or an eyelash shampoo.

Abstract: A surgical scalpel (100) is provided with a retractable guard (107) for its cutting blade (106). The guard (107) is mounted on the handle (101) of the scalpel (100) for sliding movement between an advanced position in which the blade (106) is covered and a retracted position in which the blade (106) is exposed. The guard (107) may be moved with one hand, and without requiring the surgeon, nurse and/or assistant to take his or her eyes away from the patient or the instrumentation during a surgical procedure. A two-position resiliently-biased manually-releasable detent means (113) is provided between the handle (101) and the guard (107). A closed longitudinal slot (122, 123) on the guard (107) cooperates with a pin (121) on the handle (101) to limit the sliding movement of the guard (107) independently of the detent action therebetween and accommodates the mechanical loading forces.

Abstract: A guarded finger scalpel is squeezed between the thumb and forefinger to advance a blade out of an opening. The blade is used to make an incision in the patient's skin, thereby facilitating insertion of a catheter and its line in a patient. Thereafter, the manual pressure is released, and the blade is automatically retracted. This prevents inadvertent or accidental nicks or cuts and hence eliminates or, at least, substantially reduces the exposure to the AIDS virus or other infectious diseases. A lock-off means is employed, subsequent to the surgical procedure, to prevent further blade exposure during clean-up and disposal.

Abstract: An athletic shoe (or other article of clothing) has a pocket formed therein, and an interchangeable unitary assembly is slidably received within the pocket and is retained therein by means of a flap carried by the shoe. The interchangeable unitary assembly preferably comprises a molded plastic card having a battery, microchip, speaker and on/off switch encapsulated therein and electrically connected together. A push (or "press") button is carried by the shoe and overlays the switch when the card is received in the pocket. The push button may be pushed to close the switch, so as to energize the microchip from the battery and generate an audible signal, such as a tune or message.

Abstract: Devices are provided having a polymer coating incorporating compounds inhibiting inflammation and infection, along with subsequent tissue growth onto and around the device. Preferred embodiments include catheters, tubes, and implants that abut tissue following implantation into the body, especially for use in the naso-oto-pharyngeal areas of the body, where localized chronic infection/inflammation of the tissues surrounding the implant may be decreased by sustained release of antibiotics, antifungals, antivirals, anti-inflammatories, and other compounds, such as anticoagulants and anesthetics. Preferred polymeric coatings are thin, well adhered to the underlying device, and formed of a biocompatible, non-bioerodible polymer such as polyurethane or ethylene vinyl acetate. The drug is incorporated either by solvent casting or by absorption into the solidified polymer. The drug incorporated polymer can also be used to form devices, or portions of devices, for implantation.

Abstract: A sterile blade dispenser facilitates removal of dulled used blades, as well as the mounting of sharp unused blades, on a scalpel during a surgical procedure being conducted in an operating room or similar environment. Preferably, the scalpel has a sliding retractable guard, and the combination of the guarded scalpel and the blade dispenser precludes inadvertent cuts or nicks during the surgical procedure.

Abstract: A combination guarded surgical scalpel and blade stripper (200, 300) uses the sliding guard (202, 301) in cooperation with an ejector button (238, 311) to strip a (used) blade (224, 314) from the scalpel (200, 300) thereby avoiding manual contact with the blade (224, 314) and the problems associated therewith.
