Abstract: A hinged ring for supporting the open top of a flexible bag. The ring is formed by two semicircular ring members hinged to be positioned between either of an open circular configuration and a folded configuration. A combination latch and handle member is mounted on one of the ring members and serves to latchingly engage the other ring member when folded, while also serving as a carrying handle. When the ring is open, the same latch member functions as a hook to support the ring and bag on an external surface.

Abstract: A device for generating isometric control signals in three axes is formed of a shaft having opposed pairs of strain gauges mounted thereon at angles to the shaft axis. One end of the shaft is fixed and the opposite free end is operable by the fingers. Electrical circuitry for combining the signals to produce useful outputs is also disclosed.

Abstract: A method of forming a pair of identical spherical mirrors having their centers of curvature separated in space. A blank having substantially parallel planar front and rear surfaces is provided. The front surface is scored to divide it into two surface segments. The entire front surface is then ground to a spherical shape. The blank is then bent along the scored region to separate in space the centers of curvatures of each of the surface segments.The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention. In order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.

Abstract: A multiple capacitor and method for making the same. A single capacitor section is wound in the usual manner from two metallized films. After the winding has progressed through the proper number of turns for one of the capacitors, the metallized layer is removed from the surface of at least one film over a selected distance. An insulated sheet having a length sufficient to encircle the capacitor at least once is inserted between the film layers to extend beyond at least one end of the wound cylinder. The ends of two additional dielectric strips are inserted into the capacitor winding between the metallized films. Winding is then completed and each end of the wound section is metal plated. Leads are then attached to the ends of the capacitor section, resulting in a plurality of capacitors having different voltage ratings but wound within a single capacitor section.

Abstract: A test circuit for use with a boiler control circuit. A test switch and a lamp are connected between ground and a water level electrode. In the presence of a water path, a sufficient potential drop exists between ground and the electrode to light the lamp when the test switch is closed. If a ground or short exists, the lamp will not light.

Abstract: An improvement in the method of assembling a pair of windows and a spacer by amalgamation to form a sampling cell. The improvement comprises evaporatively depositing a thin layer of metal on each of the windows prior to amalgamating them with the spacer.

Abstract: An intra-uterine device comprising a support member and a plurality of branch members connected to said support member and extending from all sides of said support member, said support member and branch members being inflatable and being adapted so as to fit substantially entirely within the uterine cavity of the user thereof.

Abstract: A colposcope including a camera selectively mountable to take photographs along one optical axis of the binocular microscope and a flash unit for illuminating the field of examination along the optical axis of the colposcope illuminator by means of a mirror selectively postionable in the optical axis of the illuminator.The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention. In order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.

Abstract: A table leg supporting structure is formed by a pair of metallic side rail flange members mounted at right angles to each other on the underside of a table top and abutting each other to form a corner therebetween. A hollow tubular leg has a ninety degree sector of its sidewall removed in proximity to its upper end, and a ninety degree angle member welded therein. A machine screw passed through a hole drilled in the corner junction of the paired flange members is threaded into the angle member within the tubular leg. The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.

Abstract: A flat top table has opposed pairs of legs disposed in spaced relation from the periphery of the table top when in their extended upright positions. Each pair of legs is mounted on a rigid cross bar pivotally supported on a first axis of a frame secured to the underside of the table top. Rotatable handle means mounted on said frame and rotatable about a second pivotal axis are coupled to the legs at the first pivotal axis by an eccentric linkage whereby the legs are locked in either their upright position, or in a folded position at ninety degrees thereto, whenever the handle means is rotated beyond the pivotal center of said eccentric linkage. The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention. In order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.

Abstract: A removable, disposable molded plastic tip for use with a spring-loaded plunger-actuated vacuum pipette. The discharge end of the tip is provided with a solid porous filter member designed to filter a sample fluid during either of fluid entry into, or discharge from, the tip.

Abstract: A noise reduction barrier is formed by connecting together a plurality of prefabricated vertically oriented panel members so configured that a hollow tubular wall is formed between opposed panels. The space between panels is filled with sand or loose earth which provides the mass to make the structure sound retardant. In alternative embodiments, for increased sound absorption, perforated sheet material may be secured to the outer edges of the barrier wall and the interstices filled with rock wool or similar porous material.

Abstract: There is disclosed a pressurized Freon cylinder having a cap including a threaded nipple with a puncturable end wall. Positioned within the nipple, by screwing into its internal threads, is a porous plastic filter in the path of the fluid as it leaves the container.

Abstract: There is disclosed a wound capacitor which is designed to open an external circuit upon capacitor failure. This is accomplished by dividing the foil at each end of the capacitor into two regions. A lead is then connected to each region so that the completed capacitor has a total of four leads. The two leads at each end of the capacitor become a part of the external circuit. A capacitor failure thereby causes an open in the external circuit.
