Abstract: A retention system includes a retainer having at least two wings affixed to a mounting surface by a retaining screw or like attachment device inserted into a hole of the mounting surface. A coil spring or the like, optionally captured by the retaining screw, provides tension between the retainer and the mounting surface. The hole of the mounting surface defines the potential placement of the retainer relative to the mounting surface, allowing it to assume a neutral position and a plurality of offset positions. While in its neutral position, the wings of the retainer prevent the removal of connectors, cables, screws, or other retention devices by physically trapping them between the retainer and the mounting surface. By moving the retainer to one of the plurality of offset positions, a user may expose one of the connectors, cables, screws, or other retention devices, allowing it to be removed while preventing the accidental or inadvertent removal of the other components still trapped by the retainer.

Abstract: Methods and compositions for selectively inactivating viruses in biological compositions, including contacting the composition with an organic solvent and an ethyleneimine oligomer inactivating agent, are disclosed.

Abstract: Subjects may be screened for possible lung inflammation by a breath luminescence measurement apparatus and technique. The apparatus comprises a photon counter with special provisions for the exclusion of light from sources other than the patient's breath. A special light exclusion mask is used together with tortuous breath exhaust passages to exclude external light. A gauze plug in the breathing tube excludes light emitted by the patient's mouth tissues. Luminescence measurements higher than normal for healthy persons of the same age as the patient are indicative of lung inflammation.

Abstract: Subjects may be screened for possible lung cancer by a breath luminescence measurement apparatus and technique. The apparatus comprises a photon counter with special provisions for the exclusion of light from sources other than the patient's breath. A special light exclusion mask is used together with tortuous breath exhaust passages to exclude external light. A gauze plug in the breathing tube excludes light emitted by the patient's mouth tissues. Special adapters are provided so that the photon counter can be used for endoscopic measurement of internal tissue luminescence and for sample luminescence measurements.

Abstract: A bushing removing tool which includes an elongated handle portion and an operative head extending transversely of the handle portion and to one side thereof. A hook projection at an end of the operative head faces away from the handle portion and is engageable with the interior of a tubular bushing while a portion of the operative head remote from the hook projection acts as a fulcrum so that the tool can be swung to cause the hook projection to free the bushing from a bushing support.
