Abstract: A template set for inscribing a plurality of curvilinear figures with pencil, inking pen or other marking means is disclosed. The invention comprises a two-part unit for small circles, or a three-part unit for larger circles, enabling an individual circle or family of circles to be drawn without a compass, where such circles have a common center. The device can further be used to draw ellipses of varying size, the ellipses having varying sizes and degrees of eccentricity, and having common foci. The device consists of an exterior holder, an interior holder, a large-circle guide portion and a small-circle guide portion. In the embodiment for drawing large circles, a shim is used to maintain the large-circle guide portion in spaced relationship from the drafting medium.

Abstract: Contiguous puncturable containers of water and ethylene oxide are provided as a unitary device to provide successive introduction and vaporization into a chamber in which there are contained objects to be sterilized. The containers comprising the unitary structure are opened in succession to provide necessary humidity followed by the introduction of ethylene oxide gas, where both substances are necessary for accomplishing effective sterilization.

Abstract: Apparatus for processing plates for waterless lithographic printing comprises a first and second pair of driving rollers and washing tray in a first zone, a third and fourth pair of driving rollers and reciprocating brushing roller in a second zone, a fifth and sixth pair of driving rollers and a finishing roller in a third zone, and a seventh pair of rollers serving as an exit-drive means; a plurality of tanks is provided for holding treating solutions, with pump means for applying the solutions to the plate in the respective zones. The reciprocating brush is constructed to have a minimum mass, to impart as little vibration to the apparatus as possible.

Abstract: A pair of matched, serrated cams can be used as an adjustable shim to fill the gap between two fixed abutments. The overall length of the shim is externally adjustable after installation. Each matching cam may have more than one ramp surface, depending upon the conditions of restraint of the shims in a particular application.

Abstract: Means for protecting non-metallic and decorative metallic portions of a long gun are disclosed. The means comprises a flexible cover having an elastic portion, fastening means and an opening for the functional mechanism, and permits the gun to be used with the cover in place.

Abstract: A method for sterilizing medical devices is disclosed. The method comprises the circulation of a sterilant gas through a contaminated device bacteriologically to sterilize exposed surfaces, permitting the sterilant gas to remain within the lumen of the device for an effective period of time, and thereafter removing the sterilant gas by purging with sterile air or other inert gas.

Abstract: Apparatus for holding medical and other devices while sterilant gas is passed over and through the device. The apparatus comprises an inflatable cuff which inflates by interior pressure as the pressure in the sterilizer chamber decreases, and relaxes as chamber pressure increases, thereby alternately holding the device and exposing its surfaces to the sterilant gas and desorbing gas.

Abstract: Method and apparatus for sterilizing medical devices and the like. The apparatus comprises means for the recirculation of a sterilant gas and a diluting gas through narrow passages in the medical device in sufficient quantity and for sufficient time to sterilize bacteriologically, and then to aerate, exposed passage surfaces. The method comprises the circulation of a sterilant gas through a contaminated device bacteriologically to sterilize exposed surfaces, and thereafter to remove the sterilant gas by purging with sterile air or other inert gas.

Abstract: A circular centrally-apertured precision torch-cut web disk plate is drivingly rotatably supported between two clamp plates; and the leading end of straight rim strip stock, of length requisite for the tooth bearing rim of the gear, is positioned adjacent the web disk edge and is forced by a floating forming roll pair into conformity with the disk edge, and tack welded in the conformed rim length portion to the disk edge. By driving advance or rotation of the disk, the rim strip is drawn under the forming rolls, continuously forming it to the disk edge, to which the strip is continuously welded as formed. A complete rotation of the disk results in the strip conformed to and welded to the disk periphery as a rim flange, with strip ends brought into adjacent and near-abutting relation, said ends being transversely fill-welded together thus to form a gear blank.

Abstract: A safety line for use in industrial and other construction is combined with a take-up reel and braking device. The mechanism is maintained in a housing attached to harness device worn by the worker, with the line being attached to a suitable structural component. When the line is paid out slowly, the take-up mechanism serves to keep the slack line from interfering with normal operations; if the line is paid out rapidly, as when the worker falls, the braking device serves to snub the line before the worker can fall far enough to incur injury. A locking device prevents line movement, if desired.
