Abstract: Electric blower assembly wherein air expelled by centrifugal force from impellers passes through volute chambers disposed peripherally with respect to said impellers and each defining a space which is increasingly larger as the distance from the impellers increases, whereby smooth air flow is produced in the volute chambers since the speed of air flow therethrough is lessened and pressure therein becomes static pressure. From the volute chambers air passes along inclined channels and then around a drive motor, whereby the drive motor is cooled. In entering at least part of each volute chamber air from the impellers comes into contact with a volute chamber wall extension which becomes gradually lower in a direction opposing that of impeller rotation whereby noise due to contact of a volute chamber wall by all portions of the air from the impeller does not occur simultaneously and a quieter blower assembly is provided.

Abstract: A coupling for sealing two tubes together in end-to-end sealing engagement, comprises an outer tubular sleeve having an interior bore with a plurality of radially extending grooves therein at spaced axial locations and an inner tubular seal arranged within the outer tubular sleeve and having an exterior wall with radially outwardly extending ribs which engage into the respective grooves. The seal has an interior bore with an entrance diameter at each end at least as large as the tubes to be joined or larger so as to have an inwardly tapered entrance. The seal includes a bore wall defining a compression flange with an inwardly, gradually tapering wall adjacent each entrance which tapers inwardly in an axial direction for diameters substantially smaller than the tube. The compression flange also includes an opposite steeply tapering wall which extends in an axial opposite direction to the gradually tapering wall. A lip of less axial length than the flange is spaced axially inwardly of the flange on the seal member and has a minimum diameter substantially the same as the minimum diameter of the flange. The seal member has a first portion between the flange and the lip which accommodates the deflection of the flange and a second portion inwardly of the lip toward the center of the seal which accommodates a deflection of the lip. The flange is sized so that it will be deflected by the tubular member up to a point at which it engages the rear part of the lip which is also deflected into an undercut part of the seal member which has a diameter less than the exterior diameter of the tube to be joined. The seal also advantageously includes a centering flange at the center thereof which has a diameter much smaller than the diameters of the tubes to be joined so that they do not come into engagement.

Abstract: A method and related apparatus for the reliable determination of a random coincidence count attributable to chance coincidences of single-photon events which are each detected in only a single detector of a scintillation counter utilizing two detectors in a coincidence counting technique. A first delay device is employed to delay output pulses from one detector, and then the delayed signal is compared with the undelayed signal from the other detector in a coincidence circuit, to obtain an approximate random coincidence count. The output of the coincidence circuit is then applied to an anti-coincidence circuit, where it is corrected by elimination of pulses coincident with, and attributable to, conventionally detected real coincidences, and by elimination of pulses coincident with, and attributable to, real coincidences that have been delayed by a second delay device having the same time parameter as the first.

Abstract: A time duration is measured precisely and with high resolution by making three time measurements as shown in FIG. 5. The time difference tA between the leading edge of a start signal and the next following leading edge of a constant frequency time base signal is measured. The number "n" of the following leading edges is then counted including the leading edge of the time base signal following a stop signal. The number n is multiplied by the period TQ of the time signal. The time difference tE between the leading edge of the stop signal and the next following leading edge of the time base signal is measured. The real time difference  DELTA t is then calculated as follows  DELTA t=tA+nxTQ-tE. A three part real time measurement is performed to correct the calculated result for drift and aging. Calibration measurements are made and the respective calibration factors are used in calculating the final results. The respective circuit arrangement includes a start channel, a stop channel, and the corresponding supporting circuits.

Abstract: A windscrew is a wind rotor characterised in that it rotates when the axis of the rotor is at right angles (fig. 1 and 2) to the wind and when it is located in the direction of the wind (fig. 3 and 4). It operates with unmodified efficiency also in all positions between the vertical (fig. 1 and 2) and the horizontal position (fig. 3 and 4) and always turns the same surfaces towards the wind irrespective of the position of the rotor shaft (B). The rotor wings have a somewhat cambered surface (fig. 1 and 3). The said factors have enable solution of the difficulties inherent in designing a rotor for use at low wind velocities (fig. 1 and 2) and in storms (fig. 3 and 4). The rotor consists of two wings helically twisted about their axis of rotation (fig. 2) by 180 degrees and with a cross-section consisting of two semi-circles (fig. 4x1 and 4x2). The rotor does not comprise end plates and it is possible therefore for the air flow to pass through it from its end (fig. 4) for when the rotor is in the horizontal position it opposes the wind with only one circular surface (fig. 4). The rotor also includes a foundation (C.D.) enabling it to rotate vertically (fig. 1 and 2), horizontally (fig. 3 and 4) and in all intermediate positions while at the same time following the direction of the wind.
