Title: Cooling system
IPC: F28F9/22
Filed: 1972-04-12
Abstract: 1395338 Cooling towers; tubular heat exchangers HALL-THERMOTANK INTERNATIONAL Ltd 6 June 1973 [12 April 1972] 16762/72 Heading F4K and F4S A primary liquid (water) cooled in a cooling tower 1 by contact with a stream of cooling air, collects in a reservoir 7 wherein it serves to cool a secondary liquid (also water) passing through conduits 14 extending through the reservoir, the secondary liquid then discharging e.g. via an outlet 21 to a point of use such as a refrigeration plant whilst the primary liquid is recirculated via a pump 9 and conduit 8 to means such as a spray head 5 at the top of the tower 1. In the tower 1 which contains the usual fill material 6, the cooling air, and primary liquid may be in counterflow or cross-flow relation, and the air stream may be moved by a forceddraught fan or fans used additionally or alternatively to an induced draught fan. Fig. 3 shows the reservoir 7 wherein are the tubes 14. These are arranged in groups in channels (19, Fig. 4) defined by baffles 17. A false bottom to the reservoir above the tube assembly is formed by plates 22 except along one side of the reservoir where an inlet channel 12 allows the primary liquid to flow beneath the false bottom (inlet 24, Fig. 4) in a sinuous path over the tubes to an outlet 25 leading to an outlet passage 13 from which the primary liquid discharges via the pipeline 8 conveying it back to the spray head 5.

Title: Process for suppressing electric discharges
IPC: H01H85/38
Filed: 1927-06-24
Abstract: 273,322. Siemens - Schuckertwerke Ges. June 25, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Fusible cut-outs.-An electric discharge such as the arc set up when a fuse blows is suppressed by introducing into the path of the discharge a substance that absorbs electrons or ions, or a material from which such a substance is generated bv the action of the arc. The fuse 1 is enclosed in a tube 2. If the wire 1 is of silver, the extinguishing substance consists of halogens or their compounds, e.g. iodic acid anhydride (I2 O3). This compound is dissociated by the heat of the arc, the iodine atoms combining with the silver ions, and taking up free electrons forming negative iodine ions that interfere with the discharge. Halogen compounds of silicon or boron nitride may also be employed. In addition, a non-conductive filling substance may be mixed with the quenching substance, and an inflammable mixture 10 may be employed to destroy the wire. A " driving-medium " may be admixed for the purpose of clearing the tube. This substance may contain metallic compounds such as saltpetre. The tube 2 may be enclosed in an outer tube 5 having caps 6. 7 connected by wires 8, 9 to the caps 3, 4 of the inner tube 2.

Title: Improvements in control devices for aircraft
IPC: B64D39/00
Filed: 1948-07-05
Abstract: 653,779. Controlling aircraft. ROBERT. R. A. July 5, 1948, No. 18062. Convention date, July 30, 1947. [Class 4] A control system for an aircraft or guided missile comprises means which are operative on a control surface only at speeds higher than a given value and are adapted to change the orientation of a reaction jet at speeds below that given value. The controlling means shown comprise a jet nozzle 58 universally mounted on stub shafts 53-56 and control surfaces 21-24, rotatably mounted on shafts 25-28 respectively which are disposed perpendicularly to the aircraft's longitudinal axis at 90-degree intervals. A .cylinder 29 carries the nozzle 58 supported in a ring 52 on extensions 50, 51, and is mounted in frame members 30, 31 for sliding movement, under the action of the jet thrust, against the restraint of elastic cords 96. A yaw control motor 90, Fig. 2, is mounted on the cylinder 29, its operating arms 89, 89<SP>1</SP> turning shafts 86, 91 through links 87, 88<SP>1</SP> respectively. A pitch control motor 82 also mounted on the cylinder 29 has operating arms 81, 81<SP>1</SP> connected by links 80, 80<SP>1</SP> to crank-arms 79, 791 on shafts 69, 69<SP>1</SP> respectively. Rotation of the shaft 69 by the motor 82 actuates, through an arm 68, a link 67 and a further arm 66, a stirrup member comprising arms 59, 60 integral with stub shafts 53, 54, and arcuate cross arms 61, 62 engaging plates 63, 64 (Fig. 1, not shown), on the forward end of the nozzle 58. The nozzle is thus rotatable in a vertical plane by the pitch control motor 82 but is free to be' rotated in a horizontal plane about stub shafts 55, 56 by an arm 83 connected to the latter and to one end of a link 84, the other end of which is connected to an arm 85 on the shaft 86 which is rotated by the yaw control motor 90 in the manner described above. The amount of control exerted by the surfaces 21-24 is varied automatically according to the jet thrust by arranging lever arms of variable length between the operating shafts 69, 691, 86, 91 and the respective surfaces 23, 24, 22, 21. One such lever arm is shown in Fig. 4 and comprises an arm 71 integral with the shaft 69 and carrying flanges 72, 73 slidably engaging a block 74. A spherical recess in the block 74 houses the ball end 75 of a finger 76 which terminates in a plate 78 rigidly connected to the surface 23. It is so arranged that when the full jet thrust is being developed the cylinder 29 is moved forwardly until the shaft 69 is coaxial with the ball 75, rotation of the shaft then serving only to orient the nozzle 58. As the thrust decreases however the resilient cords 96 move the cylinder 29 rearwardly, whereby a lever arm of increasing length appears between the shaft 69 and the finger 76 and the control surfaces are operable by the respective motors. Rolling control is provided by rotating the cylinder 29 about its axis by means of a motor 42, the actuating arm 41 of which is connected by a link 40 to an annulus 38 rotatably mounted in a ring 37 and slidably connected with a plate 44 on the cylinder.
