Patent GB-2067516-A (GB)
Title: Liquid or powder dispenser
IPC: G01F11/30
Filed: 1980-01-14
Abstract: A dispenser device for liquids or powders including a metering chamber having a valve controlled inlet port (3) and a valve controlled outlet port (4), has an actuator is connected to the two valves to move them between fill and discharge conditions and is arranged to cause the inlet valve to close before opening the outlet valve during transfer from the fill to the discharge condition. The actuator includes a cylinder (31) movable over a piston (38) fixed to the body of the device and the valves respond to movement of the cylinder. Biasing means urges the cylinder into the fill position at which the inlet valve is open and the outlet valve is closed, and time delay means operates to retard movement of the cylinder during part of its travel from the discharge position to the fill position. The cylinder is moved by operation of an actuator member (36) and a latch functions to hold the cylinder at the discharge position until the actuator member returns to its initial rest position. A second latch functions to hold the actuator member in its rest position until the cylinder returns to the fill position. The two latches are interconnected so that the first is rendered inoperative by movement of the second into its latching position. <IMAGE>

Filed: 1980-03-29
Abstract: The shroud has axial side edges 26 which abut corresponding side edges of adjacent blades 23 and which lie at an angle of between 30 DEG and 45 DEG  to the rotor axis.

Title: Method and apparatus for cooling hot-rolled wire rods
IPC: C21D9/573
Filed: 1980-09-09
Abstract: A method of conveying and cooling a rod discharged from a hot rolling mill involves steps of reeling the rod into convoluted rings, forming the rings into a densely packed coil in which the centers of the rings are slightly offset non-concentrically, conveying the densely packed coil through an enclosed space, and progressively cooling the coil while keeping the temperature differences within the cross-section of the coil perpendicular to the length thereof at a minimum. This is done by adjusting the environment within the enclosed space to keep the temperature of the external surface of said cross-section of the coil substantially uniform, during the course of conveying the coil, loosening the coil at least once for accelerating the release of heat from the core of the densely packed part of the coil along each edge of the coil, and possibly supplying heat onto both the edges and/or the bottom of the packed coil on the conveyor. A suitable apparatus is illustrated, wherein the coil is loosened by passage over a step. <IMAGE>

Title: Process for the treatment of aqueous media
IPC: B01J39/04
Filed: 1980-10-29
Abstract: The present invention provides a process for the treatment of an aqueous medium containing calcium and/or magnesium bicarbonate in which the whole or greater part of the calcium and magnesium bicarbonate is removed by passing the water through a column of weakly acidic ion exchange resin, wherein the weakly acidic ion exchange resin is regenerated by first passing through a solution of an acid followed immediately by passing through a solution containing a salt of calcium and/or magnesium and/or sodium, the solutions used for regeneration being passed through the column in a direction counter to the direction of flow of the aqueous medium to be treated. In addition to weakly acidic resin 2, a column 1 may also contain therebelow a strongly acidic ion-exchange resin 3; in this case the regenerant acid and salt solution pass through resins 3 and 2 sequentially as indicated. <IMAGE>

Title: Circuit arrangement for regulating the power drawn by at least one load from a supply network
IPC: H02M5/257
Filed: 1980-12-03
Abstract: A circuit arrangement regulates the power drawn from a supply network by at least one load 50 with linear and/or non-linear current-voltage characteristics. It has a controlled switch 51 which is connected in series, and preferably a sensor circuit 54 in series and/or parallel, with the load. A regulating circuit 55 is arranged between the sensor circuit 54 and the controllable switch 51. In the input circuit of the regulating circuit 55, the actual value for the operational state of the load 50 is formed by a mean value formation of the current of the load 50. The output of a mean value former 57 forms one input quantity of the regulating circuit 55 and the output of the sensor circuit 54, determining the momentary value of the load current, is connected to the input of the mean value former 57. Thus a quantity corresponding to the mean value of the load current forms one input of circuit 55, and another input of the circuit 55 is a desired value linked in phase with the supply. <IMAGE>

Title: Reconstituted tobacco sheet
IPC: A24B15/14
Filed: 1981-02-06
Abstract: A method of forming reconstituted sheet, from ground, tobacco involves the formation of a high solids content slurry of which the particle size is less than 60 B.S. mesh. The slurry is then extruded through a single pair of rollers onto a wire mesh conveyor, or onto a continuous casting band which is itself supported by one of the rollers. The high solids content reduces the energy costs in drying the extruded sheet and the use of a single pair of rollers reduces the costs of the machinery. <IMAGE>

Filed: 1981-04-24
Abstract: An improved process for the preparation of difunctional "living" polymers by anionic polymerization of conjugated dienes and/or vinyl substituted aromatic compounds in the presence of dilithium organic compounds as initiators utilizes a dilithium adduct of conjugated dienes (e.g. 1,3 butadiene, isoprene or 2,3 dimethyl-1,3-butadiene) having 4 to 12 carbon atoms in a monomer molecule and 1 to 6 of such monomer units in a molecule of adduct. The adduct is prepared by reacting diene with 0.5 to 2 gram-atom of lithium per mole diene in 5 to 10 moles of a mixture of solvents wherein 70 to 95 volume percent is selected from toluene, benzene, diethyl ether and methyltertiary-butyl ether with the balance being tetrahydrofuran. The reaction is carried out in the presence of a polycyclic aromatic compound as promotor, preferably naphthalene, anthracene, biphenyl or stilbene. The terminal difunctional "living" polymers formed by the polymerization process can be further functionalized to telechelic polymers or used for preparation of A-B-A block polymers.

Patent GB-2082424-A (GB)
Title: Television signal ghost detector
IPC: H04N5/21
Filed: 1981-08-06
Abstract: A television signal ghost detector is provided which acquires a component of a ghost signal when one is present, after which the ghost signal component is tracked, thereby providing a continuous indication of the presence of the ghost signal and its delay with respect to the main television signal. A training signal contained within the received television signal, for instance the horizontal sync signal in inactive line ten, is applied to a variable delay line (12). When the television signal is contaminated by a ghost signal, the training signal will be followed by a ghost of itself. When the delay of the variable delay line (12) is correct, the delayed training signal at the output of the delay line will be in time coincidence with the training signal ghost at the input of the delay line. A coincidence detector (14) detects this condition, after which time the delay of the delay line is controlled to maintain the coincident condition during subsequent receptions of the training signal. The delay of the delay line is a measure of the delay of the ghost signal with respect to the main television signal. When the delay of the delay line is incorrect and the coincident condition is not established, the delay of the delay line is varied until the coincident condition occurs. In the case of a clocked delay line, this variation can be achieved by varying the frequency of a voltage controlled oscillator (18) providing the clocking signal. <IMAGE>
