Abstract: The snap action switch has a spring biased plunger carrying directly or indirectly at least one articulated contact carrier extending laterally from opposite sides of the plunger and having two convex contacts of cylindrical, semi-circular or prism configuration. These contacts cooperate with stationary contacts arranged in pairs and including at least two pairs with a total of four contacts arranged in a near-rectangle; the contacts of each pair are inclined to each other for defining a trough-like configuration for concurrent engagement with one of the contacts on the carrier. This way, a total of four contact make and break points is defined for a single current path.

Abstract: Spacer for concentrically disposed tube systems where a temperature drop exists between adjacent tubes. This may consist, for example, of a superconducting electric cable or alternatively of a tube system for carrying heated liquid or gaseous media. The concentric tubes are spaced by a winder which touches the surfaces of adjacent tubes at particular points and which consists of two ribbons of insulating material disposed adjacent to each other having two elements in-between, and one of them being wound about the other so that they touch adjacent ribbon surfaces only in isolated points.

Abstract: An analyzer such as a two beam infrared analyzer is assembled in building block fashion and includes a radiation source module and a detection module tied together by rods and in optical alignment with each other. Intermediate or "cell"-modules are hung on the rods and all adjacent, interfacing faces of the several modules are constructed for indexing, preventing lateral deflection when the fastened rods hold all parts together.

Abstract: An axle body is made by extruding a blank for forward extruding a neck portion and backward extruding a hollow shell portion, a transition zone is also produced by forward extrusion; the resulting shell portion is rolled into a nonround cross section, of, possibly, different wall thickness; two such shell portions are welded at their respective ends.

Abstract: A cluster of working bin modules resembling the cells of a honeycomb is used for storing tons of particulate commodities. This structure eliminates the need for corrugated sheet metal walls thereby reducing the explosion hazard. The bins share common smooth walls which are joined where they intersect by connectors which form hollow vertically-extending prisms. After the hexagonal modules have been erected and connected, the prisms are filled with concrete to form a watertight seal between adjacent bins and to permit the prisms to support heavy equipment mounted on top of the cluster. The hexagonal working bins are mounted on columns formed by concrete-filled vertical tubes. Each column is attached to the foundation by a ground anchor having a structure providing high shear strength to resist earthquake damage. Each column includes at its top a short hollow hexagonal prism; horizontal struts connect the hexagonal prisms of adjacent columns.

Abstract: A machine to facilitate editing of several films employs sprocket wheels spaced vertically along a central vertical shaft. The sprocket wheels are individually selectively engageable and disengageable from the vertical shaft to permit the synchronization of the films to be adjusted and maintained. In a first embodiment, the supply reels and the take-up reels associated with each sprocket wheel are supported at the same height as the sprocket wheel at the left and right sides of the machine, respectively, in stacked arrangements. In a second embodiment, the supply reels and the take-up reels are supported in terraced arrangements. In both of these embodiments, a central area of the top of the machine between the supply reels and the take-up reels is left clear as a working space, giving the operator easy access to the reels and to the sprocket wheels. Each film passes through only a single sprocket wheel, and therefore is quickly threaded and unthreaded by the operator.

Abstract: A heating and air conditioning system and method involves the use of turbomachinery and a working fluid capable of changing phase at specific temperature and pressure and powered by an external heat source. The pressure of a portion of the working fluid in liquid form is increased and thereafter heated to change phase to a gas for use as a high energy working fluid component which is flowed through the turbo-drive. Another portion of the working fluid, at an intermediate pressure is expanded to a lower pressure and then passed through an evaporator, whose output forms a low energy working fluid component in gas form. The low energy working fluid is flowed into the turbo-device for admixture with the high energy working fluid, to effect an energy exchange therebetween. The turbo-device includes an output which is condensed and at an intermediate pressure. Various systems, turbo-devices and working fluids are described.

Abstract: A generally horseshoe shaped inventory restraining device of a unitary and resilient construction comprising two arms extending from a base and having inner walls which define a longitudinally extending re-entrant cavity therebetween for clipping onto and tight securement to a rod-like merchandise display hook. A method is presented for using the device in conjunction with the merchandise display hook.

Abstract: Plural dies for stepwise drawing a hollow blank on a mandrel are spaced so that a downstream die is placed at a location where the drawing strain from the previous die has been reduced to zero because the tensile stress in the deforming zone is balanced by adhesion to the mandrel.

Abstract: Apparatus is disclosed for long-term ambulatory monitoring of blood pressure by an auscultation method, employing a pressurizable cuff and requiring no intervention by the patient. Heartbeats are sensed by ECG electrodes, and a microphone is used to sense the Korotkow sounds as the pressure in the cuff is varied. The presence or absence of a Korotkow sound within a preset interval following each heartbeat is used in determining when the cuff pressure equals the systolic and diastolic pressures. Those pressures are determined in each cycle of operation and are recorded on a continuously-running portable tape recorder, along with the ECG signals. In each cycle of operation, the initial pressure to which the cuff is inflated is based on the systolic pressure measured in the immediately preceding cycle. The pressure in the inflated cuff is thereafter stepped downward in small discrete decrements triggered by successive heartbeats during the measurement phase of each cycle.

Abstract: The feeder and the rolls are operated by separate cranks to avoid obstruction of the area in which the hollows are connected to the feeder. The two cranks are either separately driven or connected to a common drive; in either case, synchronism is maintained, and, preferably, an alternating retarding and advance component of movement is superimposed on one crank in relation to the other so that the feeder drive can take up some of the deforming work.

Abstract: A transport belt is constructed from a toothed belt as base with individual carrier elements separated by spacers. These elements each have a shallow trough with central indent and tapered base.

Abstract: Iron oxide powder, e.g., ore, is reduced in a CO/N.sub.2 atmosphere at a temperature between 750.degree. to 1200.degree. C., whereby prior to the onset of precipitation of metallic iron the content of H.sub.2 is limited to 15% (vol) of the CO content, and SO.sub.2, H.sub.2 S, COS or another suitable gaseous sulphur compound is developed or maintained in the reducing atmosphere at a range from 0.0005 to 0.1% (vol), preferably 0.001 to 0.01% (vol) in relation to the CO content.

Abstract: Ingots or castings are supported by fairly closely spaced rollers. The resulting spaces adjacent to exposed surface portions of the ingot or casting are filled with atomized water to generate a fog or mist being retained so that as much water droplets as possible vaporize by heat radiation from the ingot or casting, supplemented by radiation from the adjacent roller surfaces.

Abstract: A system for encoding, recording, playing back, decoding, validating, and displaying cardiac signals obtained from a patient during ambulatory monitoring. The system permits the recording on a single track in a magnetic tape of a channel of ECG signals interrupted intermittently by blood pressure signals, time of day signals, and event marker signals. The ECG signal is recorded in analog form, but the other signals are recorded as pulse coded signals each having its own format. In the playback apparatus, decoders identify and verify each of the signals when they occur, and the played back information is plotted on a chart. If the time of day signal was not recorded on the tape, timing information can be produced by the playback apparatus from the cumulative tape travel. Fiducial signals introduced in the recording, playback, and charting operations are used in a method for identification and measurement of recording tape speed error, playback tape error, and plotter speed error.
