Patent GB-129743-A (GB)
Title: Improvements in the Purification of Hydrogen.
Inventor: RIDEAL ERIC KEIGHTLEY
IPC: C01B3/50
Filed: 1918-03-14
Abstract: 129,743. Rideal, E. K., and Taylor, H. S. March 14, 1918. Hydrogen containing carbon monoxide as an impurity, for example hydrogen produced by liquefaction processes from water gas or by the steam iron process, is purified by submitting the gas successively to two processes by the first of which the greater part of the carbon monoxide is converted into carbon dioxide, while, by the second, the remainder of the carbon monoxide is removed by fractional combustion with air or oxygen. The impure hydrogen is mixed with steam and passed over a suitable catalyst, for example iron oxide admixed with one or more suitable promoters such as the oxides of chromium, cerium, or thorium, at a temperature of 400-500 C. The resulting mixture of gases is then cooled, mixed with a small quantity of air or oxygen, and passed over a second catalyst at a lower temperature. When using, as the second catalyst, iron oxide and a promoter of the kind mentioned above, a temperature of 250-300 C. is employed; when using copper oxide, 120" C. is sufficient. The carbon dioxide is removed from the product by lime boxes or soda scrubbers, and oxygen, if present, is removed by passing the gases over a nickel catalyst at 200-300 C.

Title: Process and machines for improving wool tops
Inventor: BULLARD LYMAN GREENLEAF
IPC: D01G99/00
Filed: 1954-02-23
Abstract: 750,281. Improving wool tops. TALBOT WOOL COMBING CO., DIVISION OF WINSLOW BROS. & SMITH CO. Feb. 23, 1954, No. 5228/54. Classes 120 (2) and 120 (3). A process for increasing the proportion of mean or average length fibres in a wool top sliver is characterised by the step of making a single continuous passage of the sliver through forward and rearward pairs of feed roll with the forward feed rolls driven at a speed in excess of the rearward feed rolls and with the said pairs of feed rolls subjected continuously and directly to equal fluid pressure. As shown, sliver to be treated is passed continuously through two pairs of feed rolls 26, 20 and 40, 35, the forward roll 20 being driven at a substantially greater speed than the roll 35. The pairs of rolls are carried in pairs of side frames 12 and 14, the side frames 12 being adjustable to permit alteration of the ratch distance between the pairs of rolls. Four pressure chambers (two only, 30 and 42, are shown in Fig. 3), all connected to the same fluid pressure supply, are arranged one above each of the journal boxes at the ends of the respective upper rolls 26 and 40. Each pressure chamber contains a flexible diaphragm which is connected to its appropriate journal box by a vertical rod. Thus all the four journal boxes at the ends of the upper rolls are acted upon by the same uniform pressure. A stop motion is provided that stops the machine should a slub or other obstruction in the sliver passing through, lift the upper rolls above a predetermined position.

Title: Improvements in or relating to fuel supply systems for multi-cylinder internal combustion engines
IPC: F02B75/18
Filed: 1948-02-24
Abstract: 652,883. Spray carburetters. CARTER CARBURETOR CORPORATION. Feb. 24, 1948, No. 5516. Convention date, July 31, 1942. [Classes 7(iii) and 7(vi)] In a multicylinder engine the cylinders are arranged in groups connected to separate intake manifolds 10, 11, Fig. 1, fed by twin carburetters 13, 14 with fuel nozzles fed respectively from passages 16, 17, Fig. 2, to which fuel is metered through orifices 20, 21 controlled by metering valves 39, 43 operated by suction to close the orifice 20 to put the carburetter 13 and manifold 10 out of action at idling, and to close both orifices at a higher suction, e.g. at overrunning. The valves 39, 43 carry small magnets 54 to provide a snap-action opening and closing, and the valve stems 18, 19 are connected to a rod 33, Fig. 3, operated by a spring-loaded piston 34 actuated by the suction downstream of the throttle valve transmitted through a passage 37. When the throttle valve is closed for idling, the suction, e.g. 10 in. mercury, moves piston 34 against a spring 38 and carries the valves 39, 43 downwards so that the valve 39 closes the orifice 20 and puts the manifold 10 out of action. At a higher suction, e.g. 18 inch mercury during overrunning, a lost-motion connection between the valve stem 18 and the rod 33 allows the piston 34 to compress a second spring 55 and move down further to cause valve 43 to close orifice 21 and put the manifold 11 also out of action. The carburetters may include ari automatic choke mechanism provided with means holding the throttle valve slightly open at starting and warming up. In this position an arm 49, Figs. 2 and 3, rotated by a link from the throttle valve operating mechanism, raises the rod 33 and opens the valves 39, 43 so that both carburetters are in operation at starting. Acceleration pumps may be included in the carburetters. Specifications 472,090 and 531,244 [Group XXXV], are referred to.

Title: Improvements in instruments for the measurement of electrical resistance
IPC: G01R27/02
Filed: 1925-02-28
Abstract: 237,829. Evershed & Vignoles, Ltd., and Midworth, C. Feb. 28, 1925. Resistances, measuring; variable resistances.-An electric resistance 7, Fig. 1, is measured on an indicator 1 with a current passing from a source of E.M.F.5 through resistances 2 and 3 arranged in series and in parallel with the indicator, 6 being a fixed resistance. As the indicator 1 varies with the amount of current passing through it and the source of E.M.F. may vary from time to time it is necessary to compensate the sensitivity of the instrument so that it can be made independent of the varying value of the E.M.F. It is essential that the resistance of such instrument shall remain constant if the accuracy of the calibration is to be maintained. The sensitivity of the indicator is controlled by varying the value of a resistor 2 in series with it in such a manner that no change is produced in the effective resistance of the complete circuit. The resistance of resistor 2 is varied by the movement of a contactor 4 so that the sensitivity of the indicator 1 may be adjusted to any desired voltage of the battery 5. The resistor 3 is connected bv a contactor 4 so that as the resistance of 2 is induced the resistance of 3 is increased and since it is in parallel with 2 the resistance of the entire circuit will tend to increase. The resistor 3 is graduated so that whatever the position of the contactor 4 the total resistance of the parallel circuits 1, 2 and 3, 6 remains unaltered. The resistor 2 is shown uniformly wound but both resistors may be graduated provided the movement of the contactor 4 produces no change in the total resistance. In Fig. 2 the resistors are arranged so that the contactor 4 moves radially to cut in or out a certain number of turns for a given angular movement. Instead of a single arm as in Fig. 2, two arms 4, 9 may be used as in Fig. 3. In this arrangement the arm 4 has a cam or other gear 8 operating the arm 9 so as to vary the rate of progression over the resistor 3. The resistors 2, 3 may be uniformly wound or graduated. The calibration is arranged by shortcircuiting terminals 10, 11 by a zero resistance and adjusting contactor 4 to deflect the indicator 1 to zero. Known resistances are then inserted between terminals 10 and 11 and the instrument calibrated. The terminals 10, 11 are then shortcircuited and the indicator noted. If the voltage of 5 is the same the pointer will indicate zero. If the voltage of 5 differs the pointer will not indicate zero. To compensate for this the contactor 4 is moved until the indicator is at zero and the unknown resistance can then be measured.
