Abstract: 1,068,259. Cooling towers. FOSTER WHEELER CORPORATION. Nov. 2, 1964 [Oct. 31, 1963], No. 44540/64. Heading F4K. A cross-flow cooling tower has a circular or rectangular housing 12, formed of frame members 15 and 16, with inlet and exhaust sides 24 and 28 for the horizontal air flow, and a basin 36 for distributing the downwardly flowing water, the housing being filled by support members 32 and slats 34 disposed transversely to the air flow; a horizontal interchange deck 42 separates an upper reach of the housing from a lower reach, the deck conveying water from the air inlet side of the upper reach to the exhaust side of the lower reach and vice versa. This deck comprises a series of troughs 54 (see Fig. 4), aligned with the direction of air flow and formed by a horizontal plate 44 and vertical walls 48. Alternate troughs are covered over half their length by roofs 50 (Figs. 3 and 4) at the air inlet side of the housing, the intermediate troughs being half-covered at their other ends, i.e. at the air exhaust side of the housing. Water flowing down the inlet side of the upper reach flows into troughs 54 either directly or off the roofs 50 and is transported to the other, i.e. covered end of these troughs, to be distributed to the exhaust side of the lower reach through nozzles 56. The cooling air is sucked through the housing by a fan 21 housed in stack 20 and on leaving the exhaust side passes through drift eliminators 26 into a centre chimney 18.

Title: Method of forming printed circuit structures

Filed: 1963-11-18
Abstract: 1,048,864. Coating with particles. CURRAN INDUSTRIES Inc. Nov. 18, 1963 [Nov. 19, 1962], No. 45444/63. Addition to 1,024,464. Heading B6G. [Also in Division H1] A multi-layer structure which forms a base for printed wiring is made by forming a layer of incompletely cured thermosetting polymer on a support member and immersing the layer in a fluidized bed of finely divided particles maintained at an elevated temperature to form a coating of the particles partially embedded in the layer. The heated particles advance the curing of the polymer and so inhibit their total immersion in it. As shown, Fig. 2, a support member 20 is given a coating 22 of a polymer, e.g. an epoxy, by heating the support member and immersing it in a fluidized bed of solid powdered polymer. While the polymer layer 22 is still plastic, the support member 20 is transferred to the upper chamber 12, Fig. 3 (not shown), of a container 10, on a pervious partition 11 of which particles of e.g. oxides of Al, Ti, Zr, or Cu, or glass or quartz are disposed. Heated gas is blown via a lower chamber 13 through the partition 11, which may also be heated, to form a fluidized bed of heated particles around the polymer-coated support. The particles are heated at least to the melting temperature of the polymer, and preferably to or above its curing temperature. The coating 24 of partially embedded particles forms a key for the subsequently deposited conductive pattern 26, which may be applied by flame spraying.

Abstract: 1,178,720. Removing Brussels sprouts from stalks. W. H. J. JANSEN. 6 Oct., 1967 [26 Jan., 1967], No. 45620/67. Heading A4C. A device for removing sprouts from Brussels sprout plants comprises a hub 1, driven in the direction of the arrow, around which a further rotatable member in the form of an annular plate 2 is mounted so as to permit relative rotary movement, and a group of four feeling chisels 3a, 3b, 3c, 3d of equal widths arranged in a ring and rotatable about an axis and secured to a respective arm 4a, 4b, 4c, 4d. That portion of each arm located opposite the cutting edge of the chisel is provided with a sleeve 5 adapted to rotate about a shaft 6 secured to the annular plate 2, the centres of these shafts 6 being located on the plate 2 at points corresponding to the corners of an imaginary square. The other side of each arm 4a, 4b, 4c, 4d is adapted to slide in an opening pierced through a respective one of four shafts 7, the centres of these shafts 7 being located on the hub 1 at points corresponding to the corners of an imaginary square. The centres of these imaginary squares coincide with the centres of the hub 1, the annular plate 2 and the group of chisels forming a ring. Arms 4a and 4c are parallel, as are 4b and 4d, both pairs being spaced apart equally from the hub 1 and ring 2. The arms 4b and 4d are located in front of arms 4a and 4c and cross them at angles of 90 degrees. Two opposite shafts 7 are each secured to an end of a helical tension spring 8, the other ends of which springs are secured to the annular plate 2. These springs 8 act directly on the arms 4b, 4d to urge the chisels 3b, 3d towards each other and at the same time transmit any relative movement to the other pair of chisels 3a, 3c. Hence the area bounded by the chisels increases or decreases depending on the cross-sectional properties of the Brussels sprout stalk, but its centre remains accurately at the centre of the hub 1 and plate 2, and will be coincidental with the rotational axis thereof. During the cutting process, the cutting is initiated by the two opposite chisels 3b and 3d which project slightly beyond the other chisels 3a and 3c. Application of a braking strap 9 slows the ring 2 relative to the hub 1, thus causing the chisels to separate to allow insertion of a sprout stem, whereupon the brake is relaxed and the chisels close upon the stem.

Title: An Arrangement for Improving the Transient Response of a Register Control System.
IPC: B41F13/02
Filed: 1968-09-25
Abstract: 1,182,860. Automatic registration control systems. SIEMENS A.G. Sept.25, 1968 [Oct.11, 1967], No.45622/68. Heading G3R. In an arrangement for automatically maintaining register in a multi-colour printing press, register error and rate of error control signals are derived from marks imposed on the web by the individual printing cylinders and combined to control a register regulating servomotor of the press. As shown the two register mark signals X1, X2 to be compared are fed to an input stage 1, which produces a signal whose length is equivalent to the time difference between the register marks and whose amplitude is proportional to the paper speed. This signal is fed to a first expander 2, i.e. an integrator and snap-action amplifier which resets the integrator at a specific integrated voltage, which produces a signal, the amplitude of which is constant and the length of which is directly proportional to the register error. This error signal is fed to the input a of a further expander 3 and simultaneously to the input of an integrator 7. The signal fed to input a of expander 3 is summed with a rate error signal fed to input b from a P.D. amplifier stage 8 and the output is integrated in integrator 4. The integrator output drives a tri-stable switch 5 into one of its states to selectively energize relays 61, 62, controlling forward and reverse running of the register servomotor. The P.D. stage 8 comprises a proportional amplifier given P.D. characteristics by an integrating RC-network with a pair of opposed Zener diodes in the input to determine the threshold values and a smoothing RC-network and a pair of opposed Zener diodes in the output to determine the threshold values to input b of expander 3. The input threshold circuit includes a resistor which may be switched in or out to vary the threshold value. If the error signal from 2 is small the error voltage produced by integrator 7 which is proportional to the length of the error signal is below the input threshold of P.D. stage 8 so that the register motor is controlled solely through the expanders 2, 3, integrator 4 and tristable switch 5. If the error voltage from integrator 7 exceeds the threshold voltage the P.D. amplifier produces a series of voltage peaks whose amplitude is proportional to the rate of increase of error voltage until the saturation value of P.D. amplifier is reached. When the smoothed output of P.D. amplifier exceeds the output threshold, which occurs for example after three error signals. The P.D. output is added to the proportional control signal in expander 3 so that the register motor is controlled by a rate error and proportional error signal. When the rate of change of error voltage reverses, the sign of the smoothed output reverses after a few pulses and exceeds the reverse output threshold so that the register motor is reversed.
