Abstract: A scanning type magnetic tape recorder comprises a deck (40) including a rotatable scanning assembly (45) and a capstan (55) mounted on the deck in spaced relation to one side of the scanning assembly. A rotary drive (41) is connected to rotate the transducer of the scanning assembly and the capstan (55) at correlated speeds. The deck also has a receiver (60) for a tape cassette (10). The cassette (10) has a supply hub (17) and a take-up hub (15) in spaced relation, contains a quantity of tabe (T) movable between the hubs, and a drive belt (20) passing on contact with portions of the tape wound on both hubs. It has an opening (12) at one end of a size to fit around the scanning assembly (45). Guides (26-34) in the cassette locate a length of the tape between the hubs, away from the belt and across the opening (12) in a position to form a turn around the scanning assembly in response to placement of the cassette in the receiver on the deck. A first roller (22) guides a length of the belt, where separated from the tape, to one side of the opening (12) for driving by the capstan (55).

Abstract: A carrier wave recovery circuit to be used in the receiving side of an image information transmitting apparatus, such as facsimile, includes an N-bit counter for counting reference clock pulses for a period corresponding to 2 L  (L is an integer) cycle periods of the carrier wave. A first latch holds the most-significant bits within the count of the N bit counter, while a second latch holds the least-significant bits within the count of the N bit counter. A frequency divider has a frequency-dividing ratio corresponding to a one-cycle period of the carrier wave, with the value of the frequency-dividing ratio being initially set by the output of the first latch. An auxiliary counter, receiving an input from the second latch, provides an output to the frequency divider for correcting the frequency-dividing ratio such that the recovered carrier wave is output from the frequency divider.

Title: A method of and apparatus for determining the mass flow rate of a fluid stream.
Inventor: JOY ROBERT D
IPC: G01F1/32
Filed: 1980-07-29
Abstract: Method and apparatus for using a single sensor to determine the relative velocity between an object and a fluid stream, the average temperature, pressure and/or density of the fluid stream, and thereby the mass flow of the fluid stream. Select properties of a signal, such as a sonic signal, directed through a vortex-street are detected using modifications of existing single sensor vortex volumetric flowmeter methods and apparatus. The modifications facilitate the measurement of mass flow by measurements of the relative energy of the signal and the temperature of the fluid as ascertained from the time delay in signal passage from a signal detecting means (43) to a signal receiving means (45).

Abstract: A method for analyzing stored image details for identification purposes is disclosed in which slopes are abstracted from an image to provide three-dimensional recognition information. Data representing light levels of an image are stored in a picture memory device, which is analyzed in a predetermined manner to select absolute illumination magnitudes between fixed locations of the image. This information is directly related to the slope between the locations. Steeper slopes and their corresponding locations are stored as recognition data in a learn mode. In an access mode, the previously-obtained information is utilized to locate new data, and depending upon the degree of correlation therebetween, an indication of recognition is either verified or rejected.

Abstract: Bei einem Wechselrichter zur Speisung von Wechselstromverbrauchern befinden sich im Ausgangskreis im allgemeinen steuerbare stromrichtungsabhängige Schaltelemente, die entsprechend der gewünschten Frequenz periodisch ein- und ausgeschaltet werden. Infolge der Stromabhängigkeit dieser Elemente kann die in kapazitiven oder induktiven Blindanteilen eines komplexen Verbrauchers periodisch gespeicherte Energie nicht zur Quelle zurückfließen, so daß Spannungsüberhöhungen und/oder Verzerrungen der Ausgangswechselspannung auftreten. Zur Vermeidung dieser störenden Erscheinungen ist ein Hilfsbelastungskreis vorgesehen, der durch einen Ist-Soll-Wert-Vergleicher steuerbar ist und dem eigentlichen Lastkreis periodisch zumindest einen Teil der Blindleistung entnimmt.

Abstract: A surface acoustic wave filter includes a length- weighted interdigital transducer (T1) to one side of which there are provided bus bar parts (BP1, BP2) which are within the acoustic aperture (A), which are inclined at an acute angle to the propagation path (P) and which closely follow the major lobe (L1). The bus bar parts (BP1 and BP2) each have a width (W) along the propagation path (P) defined by 2W=nλ/2 where n is an odd integer and X ist the wavelength of surface acoustic waves at substantially the maximum amplitude response frequency of the transducer (T1). In this case the components of the surface acoustic waves reflected from the two edges of each inclined bus bar part (BP1 and BP2) along the propagation path (P), that is to say the component reflected waves (SW1) reflected from the edge closest to the overlap envelope and the component reflected waves (SW2) reflected from the edge which forms part of one end of the transducer, are in antiphase at that maximum response frequency and so spurious signals due to the component reflected waves (Sw1 and SW2) at that frequency are substantially suppressed.

Abstract: A filtering and protection circuit (10), for use in a power distribution system including live, neutral and ground conductors (L, N, G) and having a circuit-breaking device (12) in one of the conductors, includes transient protection devices (16) connected from a common circuit point (18) to the respective conductors (L, N, G) of the system. Failure (shorting) of any one of these transient protection devices can bring about actuation of the circuit-breaking device (12). The protection devices may comprise silicon diode transient voltage suppressors suitable for high voltage applications, clamping at a rated voltage in one direction and having a forward diode characteristic in the other direction. Each such suppressor may be paired with a parallel capacitor (22) protected by its diode from surges or transient voltages. Such pairing of suppressors and parallel capacitors can enable polarized capacitors to be used in ACcircuitry.
