Abstract: ABSTRACT             In variable fill-type fluid couplings, a driving impeller and a driven runner are coupled for joint rotation by means of a liquid medium in an active liquid chamber formed by the rotating members.  The active liquid chamber is continuously bled at a selected con-stant rate and continuously fed at a rate that can be changed to control the volume of fill of the liquid therein.  Charging liquid is fed from a source to enter a mouth of the active liquid chamber.  To insure that all of the charging liquid enters the active liquid collector the mouth is provided with a charging liquid collector that forces charging liquid past the mouth and into the active liquid chamber.  The liquid collector can comprise an outer ring, an inner ring, and a plurality of pitched blades between the two rings.  The collector rotates with the driving impeller, thereby forcing charging liquid past the mouth and into the active liquid chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         There is described a method and apparatus for trans-porting lengths of pipe between a pipe storage area and a drilling derrick.  A cable support is suspended from a point substantially above the floor of the derrick.  A track formed of two horizontally spaced parallel cables is suspended above the storage area, the cable track extending between the cable support and a winch which is actuatable to change the length of the cable track.          Pipe grapples are suspended from the cable track to be movable therealong, the grapples being adapted to releasably grip a length of pipe.  A second cable or cables are arranged to control the movement of the grapples along the cable track, these cables being attached at one end thereof to the grapples and are thereafter arranged to extend to and pass around a pulley suspended above the floor of the derrick and thereafter to extend to a second winch located adjacent the first winch connected to the cable track.  The elements of the apparatus are arranged so that the length of pipe may be supported in a substantially vertical position by the grapples to thereby facilitate the connection or release of the pipe to or from a downhole length of similar pipe.

Abstract: INVENTION:  PEAK AMPLITUDE DETECTOR          INVENTOR:   WILLIAM A. COLE     ABSTRACT OF THE DISCLOSURE     An electronic device for generating a signal indic-ative of the peak magnitude of an alternating voltage signal is described.  The device includes a voltage-to-current converter that generates a current signal comprising a quiescent current and an alternating current signal which varies directly with the alternating voltage signal.  A current sink absorbs the current signal up to a controllable maximum current level.          A charge current is generated when the current signal exceeds the maximum current level, and is delivered to a capacitor.          Feedback circuitry varies the maximum current level of the current sink directly with the resulting capacitor voltage.          The capacitor voltage is consequently indicative of the peak magnitude of the alternating voltage signal.  A discharge current is applied to the capacitor so that the capacitor voltage can decrease in response to a decrease in the peak magnitude of the alternating voltage signal.

Abstract: ABSTRACT OF THE DISCLOSURE      A simplex radio transmitting and receiving apparatus has a transmission blocking means which prevents selection of the transmitting mode of the apparatus is a signal of predetermined strength is being received by the apparatus at the time the press-to-talk key is operated.  An over-ride circuit enables the blocking means to be disabled in an emergency or if another transmitter has been left operating in error.  The over-ride circuit can be activated by, for example, repeated operation of the press-to-talk key, and ceases to operate when the key is released to return the apparatus to its receiving mode.  Also disclosed is a transmission control means which can be used to modify existing transceivers to operate in accordance with the invention.

Abstract: ABSTRACT OF THE DISCLOSURE:         Process and device for increasing the rate of solu-tion of gas in a liquid.  A mixture of a liquid and gaseous component is fed into a covered channel for secondary mixing, said secondary mixing channel being disposed in an elongated circulation oxidation ditch.  The energy of the mixture flow-ing out of the secondary mixing channel impels the liquid in the channel in the direction of the longitudinal axis of such channel, and increases the rate of solution of the gas in such liquid.  At the same time, the gas-liquid discharge ratio is decreased while the rate of liquid component discharge is increased.

Abstract: ABSTRACT A paging receiver comprises: a receiving section for receiving a carrier wave modulated with a calling signal including a first signal sequence and either a second or a third signal sequence which follows the first signal sequence,  A power supply control supplies power to the receiving section in response to a first control signal.  A controller section supplies the first control signal to the power supply control for a first predetermined time period in response to the detection of the first signal sequence so that the controller section can detect the second or third signal sequence, supplying the first control signal to the power supply control consecutively in order to shift the receiver to a first test mode when the third signal sequence is detected and shifting the receiver from the first test mode to a second test mode in response to a second control signal.  A switch is connected to the controller section for generating the second control signal.  The receiver can be tested for various adjustment and tests by inputting only one test code and manipulation of a reset switch.  Further, a calling test can be conducted for measuring characteristics of the receiver with one same call number and the shortest code, thereby conveniently minimizing the time required for measurement.

Abstract: ABSTRACT     A multi-colour display consists of an array of display elements each of which has the same number of faces.  Each face is differently coloured so that each element is capable of presenting a contrast to the other elements whereby a selected pattern may be formed to provide an information display.  Each display element has a body and a base.  A magnetic coil array on the base is selectively energised to provide a pre-determined pole pattern to which a magnetic follower on the body responds to place a selected face into view.  A control system is used to rotate the selected elements in the array by appropriately energising selected coils.

Abstract: ABSTRACT   An electrically conductive brush is provided for effecting simul-taneous charging and cleaning of a photoreceptor surface. The brush is constructed of alternate conductive and non-conductive segments which causes one conductive segment which is being used for charging to be electrically isolated from another conductive segment which is being used for cleaning. Thus, different voltages can be simultaneously applied to each of the segments without adversely affecting the operation of the other. A single detoning roller is also provided for removing toner particles from the brush, the detoning roller being positioned adjacent the cleaning segment to allow for the application thereto of a lower voltage than would be required if the detoning roller was used in conjunction with a charging brush of the prior art or with the charging segment of the brush of this invention.
