Title: Improved means for the production of brine and other solutions
Inventor: ROSS JAMES ROBERTSON
IPC: A23B4/02
Filed: 1961-02-17
Abstract: 904,601. Dissolving solids. ROSS & SON (NEWCASTLE) Ltd., JAMES. Feb. 17, 1961, No. 6004/61. Class 82 (1). Production of brine or other solution of regulated dilution is achieved in an apparatus comprising a percolating tank in which the solute is held in suspension in the solvent, a vessel in permanent communication with the percolating vessel for holding saturated solution, and a mixing vessel equipped with means for the supply to its lower part of saturated solution and solvent to produce a controlled dilute solution therein, the mixing and saturated solution vessels each being equipped with floatcontrolled valves so disposed as to be closed and opened when the solutions therein attain and fall from levels which are in inverse proportion to the densities of the solutions, these valves controlling the supply of solvent to the mixing and percolating vessels respectively. The position of at least one valve may be adjustable in order to vary the concentration of the dilute solution. In the embodiment illustrated, salt is charged on to a permeable tray 24 in percolating tank 1 (Fig. 2). Saturated solution is able to flow from this vessel through perforated pipe 29, and pipe 31 into mixing vessel 13, into which water may also be fed by pipes 41, 39 and cup 38 which surrounds the orifice of pipe 31. Saturated solution vessel 17 (Figs. 1 and 3), is permanently in communication with percolating tank 1 by reason of opening 19 in the wall separating them. Mixing tank 13 is equipped with float-controlled valve 42 which controls the flow of water through cup 38, while tank 17 also has a float-controlled valve 46 which controls the flow of water through pipes 49, 50 to perforated pipe 52 in percolating tank 1. Dilute solution from tank 13 passes through pipe 63 into storage tank 16. When stable conditions have been established, withdrawal of dilute solution from tank 16 causes the level in tank 13 to fall, and hence valve 42 to open, replenishment of tank 13 occurring by simultaneous inflow of saturated solution from pipe 32 and water from cup 38. Consequently the level of saturated solution in tank 17 falls, causing valve 46 to admit water to tank 1. These processes continue until hydrostatic balance between the columns of saturated solution (level SL) in tank 17 and of dilute solution (level DL) in tank 13 has been regained.

Title: Communication system in which subscriber lines are classified
IPC: H04Q3/00
Filed: 1962-02-16
Abstract: 980,924. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Feb. 16, 1962 [Feb. 23, 1961], No. 6133/62. Heading H4K. Substations are grouped according to the class of secrecy to be afforded to conversations and connections set up from a group are policed by pulses the time position of which in a recurring cycle correspond to the class of secrecy of the group so that any intruding connection of a lower class adds police pulses of an inferior position which are detected to signal the lapse in security. As shown in Fig. 1, top secret, secret, classified, and unclassified subscribers are grouped according to level in a finder/ connector stage and police pulses t 2 , t 3 , t 4 , and t 5 , respectively, are connected to fourth wires of each group over decoupling diodes. As shown in Fig. 2 the pulse t 1  is a start pulse and steps a counter comprising bi-stables 76, 77, and 78, once in each cycle. The counter has six states in each of which it opens an AND gate 97. Each AND gate 97 corresponds to a junctor or link circuit 50 in the switching centre 20 and in conjunction with a corresponding set of six AND gates 98 the AND gates 97 scan the link circuits to examine the police pulses provided by the link circuits over wires 53. All police pulses are fed over the open AND gate 97 to the AND gate 98 of the link circuit under examination. The specific police pulse fed to the originating side of the connection employing the link circuit appears on a wire 53 from the link circuit. At the time position of the police pulse, therefore, the link circuit AND gate 98 opens and over an AND gate 104 and trailing edge differentiator 65 sets a bi-stable circuit 64. Should the link circuit deliver a second and consequently inferior police pulse over the wire 53 the AND gate 98 opens a second time and, since bi-stable circuit 64 has been set, the resulting pulse over AND gate 104 is passed by an AND gate 105 to set the bi-stable circuit 106 which operates an alarm 107. The bi-stable circuit 64 is reset by the start pulse t 1  at the beginning of each cycle and the bi-stable circuit 106 is reset by a manual button. The kind of intrusion envisaged arises from operators' monitoring and trunk offering circuits or from test circuits.

Title: Improvements in or relating to heat exchange devices
IPC: F28D1/03
Filed: 1941-05-14
Abstract: 568,567. Heat - exchangers. COLTMAN, J. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 14, 1941, No. 6201. [Class 64 (iii)] [Also in Group XXII] Heat-exchange devices, more particularly intercoolers, radiators and oil coolers for internal.- combustion engines, of the kind incorporating a matrix of thin-walled elements, such as plate or film type elements, or tubular elements with or without fins, are made by providing at least the surfaces which are in fluid-tight contact with a layer of brazing material, assembling the parts, tack-welding or seam-welding the assembled matrix to maintain the elements in correct position during brazing and then heating the matrix to brazing temperature. The brazing material may be applied by electrodeposition or spraying, by rolling down a duplex metal or by using a separate brazing strip. In making a film-type radiator, an open-ended envelope 4 with projecting sides 6a may be formed by bending a shaped cupronickel sheet and lock-seaming at 11 with a strip of copper foil enclosed in the joint. This joint is then tack-welded at intervals. A pair of cupro-nickel corrugated airway elements 2 with a sheet of copper between them and on each outer side are inserted in the envelope. A number of these rivets are placed side by side alternatively with corrugated waterway elements 3, which are separated therefrom by copper foil sheets which extend between the edges 6a of the envelopes. The adjoining edges of adjacent units are then lock-seamed and cupronickel U-shaped stiffening members 14 coated with silver are then placed over the seamed edges. These joints are then tack-welded and the stiffening members then crimped. The assembled matrix is then brazed by heating for 10-20 minutes at 1090-1110‹ C. in a furnace provided with non-oxidizing atmosphere of burnt coal gas, hydrogen or cracked ammonia. The parts forming joints which are not necessarily fluid-tight may also be coated with brazing material to improve the mechanical. strength or heat transfer of the parts. The matrix may also include rigid side plates and header plates tack or seam-welded prior to brazing. The edges of the envelopes which form lock-seams may be preliminarily folded to provide a double thickness of metal. The envelope may be formed of two separate sheets. The matrix may also comprise a honeycomb of tubular elements tack-welded together before brazing, the elements being previously provided with a surface of brazing material by electrodeposition or spraying or by providing ferrules or collars thereon. In making finned tube heat-exchangers, tubular elements of flat or streamlined cross-section may be made by forming a lock-seam tube on a circular mandrel with an external wrapping of brazing foil locked in the seam, then seam- or tack-welding the joint and shaping the tube. A number of such tubes are then inserted through flanged apertures in a number of fin members and. header plates and tank-welded thereto prior to brazing.

Title: Pressure ratio sensing device
Inventor: RIMMER RONALD
IPC: G01L15/00
Filed: 1967-05-26
Abstract: 1,208,280. Fluid-pressure servomotor systems; pure fluid amplifiers. DOWTY FUEL SYSTEMS Ltd. May 6, 1968 [May 26, 1967; Feb. 9, 19681, Nos. 24501/67 and 6598/68. Headings G3H and G3P. [Also in Division F1] A device for sensing the ratio between two pneumatic fluid-pressures comprises a discharge nozzle 13 supplied with one pressure P4 at its inlet and a second pressure P2 at its outlet, a receiver nozzle 15 axially spaced from the discharge nozzle, a matching receiver 19 to which the fluid supplying the discharge nozzle is connected through a restrictor 12, and a comparator 17 to provide a power output varying in dependence upon both the pressure Po in the receiver nozzle and the pressure Pm in the matching receiver. When the pressure P4 supplying the nozzle 13 is more than three times greater than P2 the pressure in passage 21 of the switch 17 is greater than that in passage 16 to provide a higher pressure at outlet 34 towards which the power jet 24 is deflected. If P4/P2<3, the higher pressure appears at outlet 35. The outlets are coupled to a servomotor 41 which prevents surging in a compressor by operating a bleed valve 42. Changes in the sensed pressure ratio expand or contract the pattern of pressure waves from the nozzle 13 and thus change the pressure at the receiver nozzle which may be designed to provide a proportional pressure difference at the outlets 34, 35 or have a flared entry to provide a switching action. To sense high-pressure ratios, the device is modified to include a second sensing stage 57, Fig.3, connected to the first sensing stage 64 through a vortex amplifier 68. When the ratio P4/P2 passes a predetermined value, the pressure in receiver nozzle 66 and the peripheral velocity of the vortex in amplifier 68 falls, reducing the pressure Pc2 in the second sensing stage 57 and hence the pressure Po2 in the receiving nozzle 59. The power jet 54 is now deflected by the pressure Pm in the matching receiver to cause a reversal of pressures in the outlet pipes 86, 87 which may operate a bleed valve or modify fuel flow to prevent compressor surge. A mono-stable fluid switch may be substituted for the switch 53, the duct 77 being omitted. Specification 1,180, 557 is referred to.
