Title: Automatic fluid flow regulator
IPC: G05D23/08
Filed: 1975-07-07
Abstract: 1463030 Fluid-pressure servomotor systems POWERS REGULATOR CO 7 July 1975 28545/75 Heading G3P [Also in Division F2]  A flow regulator for an air distribution system includes a plate 42 movable by the pressure differential thereacross against a spring bias 43 to vary the flow cross-sectional area of an aperture(s) 32 in a tubular housing 24, the logarithm of the crosssectional area of the aperture being inversely proportional to, and the spring bias varying non-linearly with respect to, the displacement of the plate. The bias is formed by three springs 46, 48, 50 each with different characteristics and the set point is adjusted by end-plate 54 which is mounted on the threaded end of a rod 38. The rod 38 is moved against a spring-bias 62 by a bellows 34 in an adjustable tubular guide (which also acts as an end step) according to ambient temperature. A thermostat 410, Fig. 9, sends a pressure signal Pc representing temperature to the bellows to adjust the rod 38 and thus the plate 42 to vary the flow according to temperature. The thermostat 410 has the upstream pressure P 1  fed to chamber 422 via restriction 420 and the downstream pressure P 2  fed to chamber 424. The two chambers are separated by a diaphragm 425 carrying a weight 426 and centrally apertured. The diaphragm moves away from a seat 427 to inter-connect the chambers according to the pressure differential thereacross and maintains a constant pressure Ps relative pressure P 2 . Ps is applied to a nozzle and flapper element 414 via restriction 434 so that as the flapper 440 moves to connect the chamber 436 to chamber 424 with the change in ambient temperature sensed by bellows 444 the signal pressure Pc is a function of temperature but referenced to P 2  so that the rod 38 is pressure balanced with respect to pressures P 1 , P 2  modifications of the flow regulator which do not require the referencing to pressure P 2  are described with reference to Figs. 4, 7 and 8 (not shown).

Title: Improvements in or relating to the operation of electrical discharge devices
IPC: H03F3/54
Filed: 1930-09-25
Abstract: 370,021. Valve circuits. RIGGS, A. S., 1, 5th Avenue, New York, U.S.A. Sept. 25, 1930, No. 28745. Convention date, Sept. 25, 1929. [Class 40 (v).] The cathode of a thermionic valve is maintained sufficiently negative to its associated electrodes to keep the discharge current at saturation, the signal input being applied in series with the cathode (i.e. so that the cathode potential varies with respect to the other electrodes) while one of the other electrodes is connected to a load circuit and another to a point of zero alternating current potential. Fig. 7 shows a single stage high frequency amplifier in which the discharge current is kept at saturation by applying a positive potential to the grid, the input applied across Lc being amplified across the output impedance Ro in opposite phase. The current variations due to the signal are amplified in the grid circuit across resistance Ro, the current being independent of the value of Ro between wide limits. As the discharge current is constant for a wide range of potential difference between the cathode and other electrodes the apparent resistances of the input and output circuits are infinite. Signal voltages between cathode and plate should have insufficient amplitude to produce a reversal of current due to negative resistance effects caused by secondary plate emission. Fig. 8 shows the invention applied to a tetrode, the action being the same as in Fig. 7 except that the voltages e and eo are in phase and the output alternating current resistance is finite. Fig. 8a (not shown) is a modification of Fig. 8, whereby the input and output resistances are made infinite by changing over the circuit connections of the plate p and outer grid g2. Fig. 9 shows a receiver according to the invention comprising three high-frequency amplifiers V1, V2, V3, a detector V4, the plate voltage of which is adjusted for rectification by potentiometer R2, and a low-frequency amplifier V5, the d.c. voltage of which is determined by resistance R1. Reference has been directed. by the Comptroller to Specifications 185,167 and 186,138, [both in Class 40 (v), Wireless signalling &c.].

Title: Method and apparatus for regulating input/output traffic of a data processing system
IPC: G06F11/34
Filed: 1973-06-19
Abstract: 1412051 Data processing systems BURROUGHS CORP 19 June 1973 [3 July 1972] 29094/73 Heading G4A  The system has a processor which can communicate with a number of peripherals. Data transfer is prevented if a traffic loading value indicative of the number and type of concurrent data transfer exceeds a certain threshold value. If the system uses several input/output control units the threshold values of the units are adjusted to ensure balanced use of the units. In the embodiment disclosed the processor comprises a number of modules (11, 13, 15, 17, Fig. 2, not shown) connectable to peripheral units (31, 37, &c.) via data buses (25, 27). Each bus is associated with an input/output multiplexing control unit (19, 21), and each control unit with a traffic regulator. Each I/O control unit (e.g. 19, Fig. 3, not shown) comprises a decoder (59) which, on receipt of an interrogating signal from a module, provides an input to an AND gate (61) within the unit. When a fresh peripheral is to communicate with the processor a logic circuit (75) in the regulator (55) increments a counter (83) by an amount which depends upon the type of peripheral involved, e.g. tape or disc. Similarly the counter is decremented when a peripheral ceases to use the I/O unit. The counter output consequently indicates the current total traffic loading imposed on the unit by the peripherals concurrently using it. In order to prevent too many peripherals using the I/O unit, which would result in incomplete data message transference, the counter output is compared (85) with a threshold value (77). If the loading is less than the threshold a signal is passed to the AND gate (61) in the I/O unit, which, subject to certain other signals being present, provides an output to the module indicating that communication with the peripheral can take place via that I/O unit. The threshold value may be determined experimentally. In order to ensure that the loading on the various I/O units is well balanced the thresholds may be adjusted during operation, the threshold of a busy unit being reduced so that it refuses a fresh peripheral when a less busy unit is available. The I/O units are used in sequence, i.e. if a first unit is fully loaded it refuses a fresh peripheral, the peripheral being dealt with by the next I/O unit not fully loaded.

Title: Improvements in catalysts for carrying out destructive hydrogenation and cracking processes
IPC: B01J23/90
Filed: 1930-09-29
Abstract: The cracking or destructive hydrogenation of hydrocarbons such as tars, mineral oils or their distillation, extraction or cracking products or residues is effected in the presence of catalysts obtained by thermally decomposing the carbonyl compounds of chromium, molybdenum or tungsten alone or in admixture with each other or with the carbonyl compounds of iron, nickel or cobalt.  The decomposition may be effected in the presence of carrier substances such as solid inorganic compounds containing oxygen and especially hydroxides, carbonates, borates, silicates, phosphates, and similar salts having a basic reaction of the metals of the first to the third groups of the periodic system which may be employed alone as carriers or precipitated on further carrier substances such as pumice, artificial zeolites, or silica gel and then used alone or in admixture with each other or with other substances.  The vaporized carbonyl may be passed, with exclusion of oxygen, through a tube containing the carrier substance heated to slightly above the decomposition point of the carbonyl, the finely divided metal being precipitated on the carriers.  Alternatively the carbonyls are dissolved in an inert solvent such as hexane or benzene and the carrier is impregnated with the solution.  The activity of the metal catalyst is increased by the carrier which may also have catalytic activity. The activity and working life of the catalysts may be increased by converting them wholly or partly into oxides or sulphides by treatment with oxygen, or hydrogen sulphide at elevated temperatures, e.g. over 200 DEG  C. The catalysts may also be prepared by decomposing the carbonyls within the hydrocarbons during the treatment, the carbonyls being first added in gas or vapour form, and carrier substances on which the metals deposit may also be present.  The amount of carbonyl used may be 1-10 per cent of that of the hydrocarbons.  In an example, a catalyst suitable for cracking paraffin wax at 520 DEG  C. is obtained by heating pumice coated with magnesium oxide and impregnated with a solution of molybdenum hexacarbonyl in pure benzene, a current of nitrogen being passed through until the benzene has evaporated. In another example, aluminium hydroxide gel soaked in a hexane solution of molybdenum hexacarbonyl and nickel tetracarbonyl is heated in hydrogen to 60 DEG  C. and then to 450 DEG  C. in a current of hydrogen sulphide, the catalyst being finally treated with hydrogen at 450 DEG  C.
