Abstract: W. Williams - M. Burke 1-1 DIGITAL PBX SYSTEM                              ABSTRACT         A small capacity digital PBX-key system which uses a single processor to control the system. Since only a single processor is employed, the system is interrupt controlled. In the system, there is a codec per line, the codecs each haying sufficient programmability to eliminate the need for time slot interchangers. To provide as many as 64 (or more) channels usable for speech, tones and conferencing, two (or more) parallel, 32 channel busses are used as the group bus. The stations and trunks (ports) of the system have access to both busses through the codecs. Information is routed to one or another bus through the transmission of bus control bits from the processor.

Abstract: ABSTRACT OF THE DISCLOSURE           Selected additional voltages are utilized to modify the respective horizontal and vertical sawtooth waveforms which generate the horizontal and vertical electron beam scans in a photoelectric tube.  The added voltages are selectively applied during the respective horizontal and vertical blanking inter-vals, whereby the speed of the scan is doubled, tripled, etc., during the blanking intervals.  Since the time available during blanking is still the same, increasing the speed of the beam scan causes the beam to scan correspondingly further into the non-scanned target portion.  Thus, corresponding greater distances into the surrounding target are discharged which, in turn, circumvents charge bleeding into the active picture area, thereby precluding edge hooking.

Abstract: ABSTRACT             METHOD AND APPARATUS FOR RECEIVING A DATA SIGNAL MODULATED BY MEANS OF A DOUBLE SIDEBAND-QUADRATURE            CARRIER MODULATION TECHNIQUE            A method and apparatus for receiving a data signal modulated by means of a double sideband-quadrature carrier modulation technique in which the received signal is sampled at a rate higher than the sign-aling  rate  1/T,  passed  through  a  compensating filter, and applied to a processing system which provides  the  detected  data.  The  compensating filter is such that the amplitudes of the com-ponents at f1=fc-1/2T and f2-fc+1/2T, where fc is the carrier, are equal. An initializer enables a filter coefficient to be determined during the turn-on time of the receiver. An adjusting device allows this coefficient to be continually adjust-ed. The invention can be used in data transmission systems whose channel has an asymmetric amplitude-frequency response curve.

Abstract: PARTS FEEDING BOWL WITH ORIENTING MEANS                    Abstract of Disclosure Apparatus is disclosed for accepting an initially pre-sented population of randomly oriented elongated slender articles which terminate in an enlarged head portion, and pro-viding a high-speed output stream, wherein all said articles are commonly oriented for further mechanical manipulation.       The apparatus comprises an input bowl for accepting the art-icles, which bowl includes a rotatable central disk for feeding objects incident thereupon to the periphery of the disk.  A continuous wall member extends upwardly from the disk periph-ery about a major arced zone, the bottom of the wall member being spaced from the disk to define a gap through which the elongated portion of the articles may protrude while the heads of same continue to ride upon the disk periphery in sliding contact with the side wall.  An output section defined adjacent the periphery of the disk at the portion opposed to the arced zone receives and delivers the articles from the disk.  A con-tinuous conveying band extends about the periphery of the disk and moves with the articles in the direction of disk rotation at the arced zone.  The band separates from the disk peripheral edge beyond the arced zone and extends into the output section.          Means cooperate with the band at the output section to constrain the articles between the band and constraining means, whereby the articles are conveyed into the output section.  The band diverges from the cooperating means at the end of the output section to release the constrained articles for further mechan-ical manipulation.

Abstract: patent disclosure A "critical damped" BAR FOR A POWER CHAIN SAW by William Cumming Leith, a Canadian citizen residing at Box 157, Trail, B.C.  VlR 4L4 ABSTRACT    A "critical damped" bar for a power chain saw would use maximum energy efficiency for wood cutting, but dampen out up to 95% of the wasted energy going to the vibrations at the hand-grip, thus cutting wood efficiently while preventing the occu-pational hazard, "vibration white finger," a problem common to tree fallers, especially in B.C.  A resonant wood-cutting mode with minimum energy input, near the free end of the chain saw bar, utilizes a family of resonant harmonic vibrations (n=1,2,3, etc.) corresponding to the natural frequencies of the bar, chain links, chain speed, sprocket rpm, and tree diameter.  A Helmholtz resonator model for the chain cutter teeth, wood chip, tree interface is combined with a vibrating string model for the chain resonant harmonic vibrations, to establish a non resonant chain bar, which dampens out up to 95% of the wasted energy going to the vibrations of the fixed end of the bar, chain, engine hand-grip.

Abstract: A B S T R A C T           The problem addressed by this invention is that most electronic and other electrical equipment is designed to operate at a particular voltage level which is either AC or DC.    If the wrong voltage level or type of current is used, damage may result.            This invention solves this problem, and is distinguishable from other inventions, by sensing the voltage level, and preferably also whether the current is AC or DC.  Electrical loads are connected in parallel when the voltage is sensed to be in the desired range.   Such loads are connected in series where the input voltage is not in the desired range to produce the appropriate output voltage.  Preferably the output voltage is converted from one of AC and DC to the other of AC and DC where necessary.

Abstract: ABSTRACT OF THE DISCLOSURE In this discharge valve for a flushing cistern the valve member is moved into its open position by the release actuation of an associated actuating device.  It will normally remain in that position until the end of flushing to then drop back into the closing position.  The valve member can also be moved back prematurely into the closed position by an inter-ruption actuation of this actuating device.  The actuating device, in the present case, comprises change-over devices which, by the changed conditions in the cistern brought about by the release actuation, experience a reversal of their operating directions, such that the interruption actuation is rendered possible by a renewed actuation of the very same actuating device in the same direction as for the release actuation.  This adds to the operating convenience and imposes no limitations regarding the design of the operating members.  It furthermore permits the employment of remote controls of simple design.  Moreover, the change-over device is adapted to be returned to its starting position by the further changes in conditions prevailing in the flushing cistern due to the interruption actuation and the normal valve closure.

Abstract: ABSTRACT             A circuit for receiving voice and data signals on a balanced line, the data signal being an amplitude modulated form of a carrier signal having a frequency at least twice as high as the highest frequency in the voice band.  The circuit matches the input impedance thereof to a first nominal balanced line impedance with respect to voice signals and a second nominal balanced line impedance with respect to data signals, applies the data signals to an unbalanced data output terminal, and applies the voice signals to a terminal connected to a bidirectional unbalanced input/output lead of a PABX.  The circuit also receives data signals from a terminal connected to an unbalanced data input lead from the PABX and voice signals from the terminal connected to the unbalanced bidirectional input/output lead, mixes the incoming data and voice signals and applies the mixed signals to the balanced line while preventing the mixed signals from being fed back to the unbalanced data output lead and the unbalanced bidirectional input/output lead.  The circuit further provides a low resistance DC current path for applying sufficient operating battery to the balanced line for long subscriber loops.  The carrier signal is substantially removed in frequency from the upper limit of the voice band, thus alleviating the requirement of multistage, sharp cut-off and critically adjusted filters. However, the carrier frequency is low enough so as not to be substantially radiated from the subscriber's line or be seriously deteriorated during transmission.
