Title: Jigging conveyor immersed in a liquid with attenuation of the transmitted vibrations
Inventor: FISCHER JURGEN
IPC: B65G49/04
Filed: 1990-02-23
Granted: 2003-02-18
Abstract: Known large vibrating conveyors are not readily suitable as such for conveying bulk materials or small articles into or out of a liquid bath, because the liquid (2), as a result of its incompressibility, transmits the vibrations to other constructional parts, for example the liquid vessel (1). To remedy this, it is proposed to provide underneath the vibrating part (2) a compressible space (9) which, when suitably coordinated with the liquid bath, damps the vibrations. The space (9) is preferably gas-filled, and its damping properties can be varied by feeding additional gas via a line (16) which can be shut off by means of a member (17), or by bleeding some of the filling via a further line (18) which can likewise be shut off by means of a member (19).

Abstract: A high speed communication link between peripheral nodes and a single multi-link layer protocol (MLAP) controller with an integrated HDLC framer in a main control complex.  Peripheral nodes contain a very simple control that forwards all the HDLC D-channel data from the peripherals to a single MLAP controller, thus making the peripheral nodes small in physical size, extremely flexible to connect to new interfaces and very portable.  Accordingly it facilitates the efficient distributed deployment of the PABX.  Using the described system, the PABX itself may be distributed around a building, using a backbone high speed link.  Peripheral nodes may be located at various places in a building with peripherals such as line interfaces and associated digital telephones at locations as needed.  They need not be centralized, adjacent the main control complex, as is now required.  This facilitates the provision of a building with a flexible communication system having substantially reduced wiring requirements.  The bit rate of transmission of HDLC formatted data is changed from 16 kb/s or 64 kb/s to 2.048 mb/s and visa versa.  Plural modified HDLC packets are multiplexed to one physical link that is terminated by an HDLC framer inside the multi-link access protocol controller or, from one MLAP controller, many peripherals can be accessed and controlled.  The functions of the present invention are transparent to the end-point HDLC framers and hence to the link layer protocol and peripheral software.

Abstract: A transconductance amplifier circuit employs the known combination of a transconductance amplifier and a current comparator (with or without a range extender, preferably in the form of a two-stage current transformer) to compare the output current from the transconductance amplifier with that flowing through a reference resistor, both these currents having been derived from the same alternating input voltage. A current corresponding to the unbalanced ampere-turns in the current comparator is used to produce a feed-forward error signal that is used to modify the output of the transconductance amplifier.  The invention is characterized by an output transformer that has coaxial inner and outer toroidal magnetic cores, and primary and correction windings outside the outer core.  This primary winding receives the output current from the transconductance amplifier and the correction winding receives the error signal.  A winding located between the cores detects the error current in the output transformer (its magnetizing current), and injects this error current into the current comparator.  The secondary of the output transformer can be a single turn conductor extending through the hole formed by its toroidal cores.  The result of this circuit arrangement is that the output current in the secondary of the output transformer follows the amplitude and phase of the input voltage with a very high level of accuracy.

Title: Diverter and volume control valve
Inventor: CLARE MANAMOHAN
IPC: F16K11/052
Filed: 1994-02-03
Granted: 2003-07-15
Abstract: The invention relates to a shower control valve assembly which includes a casing mountable in a wall with inlets for hot and cold water. A cartridge is insertable into the casing in one of two orientations so that the hot water inlet of the cartridge can be aligned with either one of the casing inlets, depending on which one is the hot water inlet. The casing has at least one outlet for transporting mixed water to the tub and a diverter passage is connected to the outlet for transporting mixed water to the shower. An insert is positioned in the outlet and has a counterweighted butterfly valve member therein, the valve member being normally in an open position allowing water to flow to the tub. A rod member extends laterally of the insert and is reciprocable so as to contact the upstream wing of the valve member and force it into the stream of water flowing to the tub. The stream forces the valve member to a closed position and then the flowing water is forced to follow the diverter passage to the shower. When the water is turned off, the counterweight forces the valve member to resume its open condition. The rod member is rotatable and cooperates with appropriate means in the insert to effectively throttle water flowing to the shower to act as a volume control therefor.
