IPC: F24F3/14
Filed: 1924-08-20
Abstract: 243,061. Yamamoto, S. Aug. 20, 1924. Cooling air, tubular apparatus for; cooling air by direct contact with cooling medium.-In a process for cooling air and regulating its humidity, the air is dried by passage through alternately used chambers 1, 2 containing fuller's earth, Florida earth, or other acid clay absorber, and is cooled and remoistened by contact with sprayed water in a heat-insulated chamber 6, the heat of absorption imparted to the air in the absorbing chambers being removed by causing the air to pass through a nest of cooled tubes on its way from the drying chamber to the moistening chamber. The tubes are contained in a chamber 4 and are cooled by a water spray or air current from a pipe 4<1>. The water for remoistening and finally cooling the air by its evaporation is sprayed from a nozzle 8. The temperature and humidity of the air issuing from the outlet pipe 10 are regulated by varying the supply of water through the nozzle 8. Any water not vaporized is trapped by zig-zag plates 9.

Abstract: 1298283 Production of light sands; cellular mortars HOUILLERES DU BASSIN DU NORD ET DU PAS-DE-CALAIS and CHARBONNAGES DE FRANCE 24 April 1970 [28 April 1969] 19780/70 Headings C1A and C1H Light sands are produced from carboniferous shales in a process which comprises crushing the shales, isolating, by sieving, those grains having sizes in the range 1À25 mm. to 3 mm., and heat treating said grains before subjecting them to a final sudden expansive heating followed by cooling. Any grain agglutination may be eliminated by subjecting the product of the expansive heating to steam under pressure at the exit from the expansion chamber. The light sands produced are valuable for use in concretes, mortars and light aggregates and the residual dust can be utilized in brick manufacture. A particular application of the light sands of the invention is their use in association with fly ash to make very light mortars of the 400-700 kg./m.<SP>3</SP> class with a binder such as cement or slaked lime. Such mortars can be substituted with advantage for cellular concrete of the gas-formed or foam-concrete type subsequent to casting or similar processing.

Title: Improvements in or relating to programme control units for data-processing systems
IPC: H04Q3/545
Filed: 1969-04-18
Abstract: 1,206,902. Program controlled exchange systems. SIEMENS A.G. 18 April, 1969 [19 April, 1968], No. 19925/69. Heading H4K. A command store BFS, Fig. 1, comprises a matrix the rows of which each contain a number of sequences of individual operations in exchange equipment, such as could be involved in testing busy conditions or monitoring lines for dial impulses, the first item in each such sequence in a row being singled out by an address contained in a sub-program store MPS and the sequence being put into operation step-bystep by a command counter BFZ which steps at a fast rate up to the first item of an indicated command sequence and then steps at a slow rate to implement the items one by one. The exchange has a network KF, common control ZS and circuits such as T s , U e , exchange functions being pursued in accordance with programs obtainable by operation of one of the relays A1 to A20 in a main program intermediate store PRG. Each relay A selects a sequence of eight sub-programs in a store MPS by connecting the common point of eight code wires threading magnetic cores R1 to R8. A counter MZ connects up the other ends of the code wires one by one to obtain a coded output to intermediate store MPR which presents the subprograms one by one to the command store BFS. The first five elements of the code, set up on thyristors Th1 to Th8, mark out the row of the command store in which a command sequence is to be found, the remaining three elements of the code indicating whether the sequence is in the first half of the row or the second half, and whether, within each such half, the sequence starts from the first or the third step of the command counter BFZ along the row. The counter BFZ is an 8-stage counter that depending on the sub-program steps over columns 1 to 5, or over columns 6 to 10 slowly to effect command actions at each step, or steps rapidly to step 3 and proceeds slowly to effect command actions up to step 5, from step 5 the counter proceeding rapidly for three control steps numbered 11, 12, 13 to clear the last subprogram and obtain and register the next. A command action may be prolonged so as to allow time for operation of an exchange circuit relay by halting the command counter BFZ at any particular step for an appropriate time. If a sub-program sequence is finished before the end of a half-row of the command store, the counter BFZ may be stepped at the fast rate over the residue. Commands are executed by operation of relays such as M1 in the command store to give selective access to exchange circuit devices such as B1 in a loop circuit gated by switches T1, T2. The logic circuitry needed to drive counter BFZ from a fast rate pulse generator and a slow rate generator according to the requirements of the sub-programs is described with reference to Fig. 2, not shown.

IPC: G01N27/48
Filed: 1957-06-26
Abstract: 860,130. Electric tests. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 30, 1958 [June 26, 1957], No. 20120/57. Class 37. D.C. polarographic apparatus comprises a circuit for compensating residual current associated with the charging of the doublelayer capacity at the surface of the dropping mercury electrode, in which a small A.C. voltage is applied across the cell, and a D.C. voltage proportional to the A.C. current in the cell, itself proportional to the instantaneous capacity of the drop, is obtained and integrated, and a current proportional to the integrated voltage is combined with the D.C. current from the cell. As shown, polarographic cell PC is supplied with D.C. from a potentiometer R1 and with A.C. from a transformer T. The potential developed across a resistor R3 is amplified at 1 and fed via a lowpass filter 2 and a momentarily-operated relay contact RL2 to a capacitor C2, and thence by way of a cathode follower 4 to a pen recorder 5. The A.C. component is further amplified at 6, rectified in a detector 7, and fed through a momentarily-operated relay contact RL1 to a capacitor C3. The sudden change in the mean potential of the drop when the latter falls is used to trigger an electronic delay circuit 10, and, after a delay, a relay 11 is momentarily energized to close contacts RL1 and RL2. The voltage stored across C3, which is thus proportional to the differential double-layer capacity at a fixed time T in the life of the drop, is fed, via a cathode follower 8 to a Miller integrator 9, the output of which is fed back through a variable resistor R2 to the input of the amplifier 1. In a modification, the delay circuit and relay are omitted, the output of the detector being continuously integrated and the output of the amplifier 1 being continuously recorded.

Abstract: 641,100. Metal-vapour discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and KNIGHT, H. DE B. July 29, 1947, No. 20441. [Class 39 (i)] In a hot-cathode mercury-vapour electric discharge device, a compartment surrounding the cathode and containing free mercury on starting, has openings which allow restricted communication between the interior of the compartment and the surrounding space in the envelope, so that the free mercury in the compartment is vaporized when the cathode is heated, and a. sufficiently high pressure is established in the discharge path to enable the device to operate correctly before the establishment of such high pressure throughout the envelope of the device. A cylindrical grid 4 with a cross-baffle 5 constitutes part of the compartment surrounding the indirectly or directly-heated cathode 3. Free mercury 6 is guided into the compartment by a scoop 7 with the aid of a depression 11 formed in the envelope, when the envelope is tilted, or into an upwardly-extending scoop from the upper part of the envelope after the envelope is tilted, or from a part of the envelope where mercury is condensed after previous operation of the device, without necessitating tilting of the envelope. The mercury is retained by wire guage 9, or in an annular groove formed by a doubly-flanged washer.
