Abstract: ABSTRACT OF THE DISCLOSURE         The motor braking circuit for use with an alter-nating current motor and an AC power source includes a power circuit for supplying a DC braking current to the AC motor and a motor speed sensor which causes a mechanical brake to engage the AC motor and its load when the motor speed decreases to a predetermined value.  The DC braking current is applied to start the electrical braking cycle as soon as the AC source is disconnected from the AC motor.  The RPM sensor monitors the speed of the AC motor during the electronic braking cycle and causes the mechanical brake to engage the motor and its load when the motor speed decreases to a predetermined value to complete the stopping sequence.  The AC motor braking system can be installed without any additional direct wiring or additional hardware to the AC motor.

Title: Signal detection circuit for digital radio paging receiver
Inventor: MORI TOSHIHIRO
IPC: H04B5/04
Filed: 1982-11-18

Abstract: ABSTRACT A signal detection circuit suitable for a radio paging receiver is described. In the circuit, a carrier wave modulated with a code having n bits, where n is an integer not less than 2, is received and demodulated. The demodu-lated output is written in an n-stage shift register, where n is an integer not less than 2, in response to a clock pulse of frequency fs. The n output stages of the shift register are scanned sequentially in response to a scan signal of frequency nfs. It is determined whether or not the signals present on the output stages coincide with bits of a predetermined code. In summary, the present invention is successful in detecting a desired signal even if the beginning or head end of the received signal is unknown, because all the bits of the received signal wirtten in a shift register are compared with the desired signal during the interval between two successive times of writing received signals in the shift register. This can be accomplished with negligible additional circuit and, therefore, with quite a simple circuit arrangement. Additionally, the present invention promotes a practical increase in the number of available channels because it permits different calling codes assigned to different SC signals.

Abstract: Method of Concentrating and Measuring Unicellular Organisms Abstract A method of concentrating and measuring unicellular organism content of a sample is described.  The unicellu-lar organism containing sample is first filtered through a filter membrane impermeable to the organism to con-centrate and collect the cells on the filter membrane. The membrane containing the concentrated cells is then sequentially treated (1) with a lysing agent to lyse the cells releasing the adenosine triphosphate in the cells and (2) with a luminescent reagent which reacts with the released adenosine triphosphate contained on the filter to produce light.  Without significant effect by the filter membrane, the light produced on the mem-brane is then measured on a luminometer.  Not only does this method provide an accurate way of detecting very minute quantitites of cells, but it provides a rela-tively quick and easy method of concentrating and measuring cells in large volumes of biological or industrial liquid samples which contain low levels of organisms.

Abstract: TO ALL WHOM IT MAY CONCERN:        Be it known that We, William E. Glenn and John W. Marcinka, citizens of the United States, residing in the State of Florida, have invented an improvement in GRAPHICAL DATA APPARATUS of which the following is a SPECIFICATION              ABSTRACT OF THE DISCLOSURE      The disclosure is directed to an apparatus for deter-mining position in a data space.  A generally flat tablet is provided, the tablet being formed of a solid acoustically-conductive material.  A movable element, such as a stylus, is adapted to be manually movable over the tablet surface, the movable element having a tapered tip which contacts the surface of the tablet.  An acoustic transducer is coupled to the tip of the movable element.  Fixed transducer means are coupled to the tablet.  Means are provided for energizing acoustic energy to propagate in either direction between the transducer of the movable element and the fixed transducer means.  The midrange frequency of the energy is selected such that the wavelength of the energy mode propagating parallel to the tablet surface is a function of the tablet thickness.  Means are provided for determining the time of propagation of the acoustic energy travelling, in either direction, between the transducer of the movable element and the fixed transducer means    Each time of propa-gation is indicative of a coordinate position of the movable element.  In the preferred embodiment, the tablet is formed of plastic and the fixed transducer means are strips of piezo-electric plastic.  In this embodiment, the tip of the stylus is horn-shaped and the material of the tip has an acoustic impedance which is between the acoustic impedance of the piezoelectric transducer and the acoustic impedance of the tablet material.  This further facilitates coupling of acoustic energy between the stylus tip and the tablet.          In a form of the disclosure, means are provided for deter-mining the amplitude of the acoustic energy which has propa-gated through the tablet.  The pressure of the stylus tip on the tablet controls the amplitude of transmitted or received (as the case may be) acoustic energy.  Accordingly, the stylus pressure can be determined from the measured amplitude.  The writing pressure can be used to convey information such as the thickness of lines being hand drawn.          Adjustment of the amplitude based on the distance travelled through the tablet is achieved using a time-gain compensation technique.

Abstract: ABSTRACT OF THE DISCLOSURE          FL?NGE CONNECTION     In the case of a flange connection for rectangular air conditioning ducts which have four walls, four flange profiles with four rectan-gular angle-pieces are fitted frame-wise on the end of a duct portion.          The flange profiles are in this case substantially L-shaped hollow profiles which are in each case fitted onto a duct wall and fixed there with a plurality of spot welds.  Problematical is the seal between the inner arm of the flange profile and the duct wall, because by reason of spot welds which are situated close to but at a distance from one another, air can flow out into the free atmosphere between them and over the end face of the duct wall.  In order to achieve better tightness, there is according to Fig. 2 formed into the hollow profile a bead 29 extending from the front radial portion 19.  An inner arc 33 of the bead 29 lies with a clamping fit on the top of the duct wall 11 and presses it against the inner longitudinal arm 17 so achieving a seal which it is possible easily to implement in manufac-ture.  The arc 33 and the arc 36 which merges into the inner longitu-dinal arm 17 have relatively large radii, so that manufacturing the profile on a profile rolling plant presents no difficulties.            Application:  to the manufacture of prefabricated partial ducts for rapidly assembling air conditioning ducts, for purposes of ventilation, heating or cooling large projects.

Abstract: ABSTRACT Ammoniacal etching solution, containing metal ions as the result  of etching, is withdrawn from an etching bath, and, while part of it goes to an electrolysis cell for removal of metal ion, the remainder goes back to the etch-ing bath through a liquid jet pump in which it serves as the working liquid, while the pump sucks in from the electrolysis cell the anodically evolved oxygen. The thorough mixing of the oxygen into the etching solution performed by the pump results in oxidation so rapid that, in many cases, it becomes unnecessary to sus-pend catalyst particles in the electrolyte to accelerate the oxidative regenera-tion of the etching solution.  Where use of such particles is still desired, the solution drawn from the etching bath goes through a cylindrical filter unit from which a filtrate is drawn off laterally for the electrolysis cell, while the re-mainder of the input goes to the jet pump.  Controls are provided for using the electrolysis cell only when the metal ion concentration is above a predetermined value, far adding ammonia to the oxygen line in order to maintain a particular value of pH, and for controlling the temperature of the electrolyte in the elec-trolysis cell in order that a desired quantity of water can be condensed from the oxygen line for use in rinsing the work pieces after they have been taken out of the etching bath.

Abstract: ABSTRACT OF THE INVENTION A protective relay system for opening local and remote circuit breakers of a protected line segment when a fault occurs thereon.  The protective relay system includes local and remote fault detectors for producing local and remote blocking carrier signals, respectively, for trans-mission to  the  other  terminal  when  a fault is in the forward  direction from  the  terminal.   Reception  of  a blocking signal blocks tripping of the circuit breaker at the receiving terminal.  When the fault is internal,  the blocking signals are transmitted for only a short duration, sufficient to allow the protective relays at both terminals to detect the internal fault.  When transmission of the blocking signals stops, the trip coils at both terminals are energized because the relays at both terminals see the fault in the forward direction and do  not  receive  the blocking signal.  For an external fault the relays at the terminal  from which the  fault  is  seen in the  forward direction transmit a blocking signal to the other terminal. At the latter terminal the blocking signal is received and causes transmission of a longer duration blocking signal to  the  transmitting  terminal.   The  receivers  at  both terminals are responsive to the longer duration blocking signal to block tripping.  The duration of this  longer duration  blocking  signal  is  established  so  that  the external  fault  is  cleared  by  other  protective  relays before transmission of the longer-duration blocking signal terminates,  thereby preventing tripping at the terminal where the fault was originally detected in the forward direction.

Abstract: ABSTRACT           High voltage electronic contacts (S,S') and associated devices including TRIMOS (MOS TRIacs) devices connected in anti-parallel fashion between two terminals (S1/S'2, S2/S'1).  Each electronic contact (S, S') is controlled via a control terminal (S4) and one of the two other terminals (S1/S'2, S2/S'1), the impedance conditions of these auxiliary contacts (NA, NB) being opposed.  A power protection circuit associated to the TRIMOS device allows the flow of a relatively high current through the electronic contacts (S, S') for the lower voltage range across it, and minimizes the power dissipation in the contacts in the higher voltage range, i.e. when abnormally high signals are applied to the contact.
