Title: Improvements in or relating to power transmission systems
IPC: F16D67/00
Filed: 1930-09-25
Abstract: 365,998. Facilitating changing speed ; facilitating disengaging dog clutches. SINCLAIR, H., 6, The Crest, Surbiton, Surrey. Sept. 25, 1930, No. 28683. [Class 80 (ii).] In order to relieve of all torque in a sliding- gear change-speed gear or dog clutch driven by an hydraulic coupling, the intervening shaft is turned slightly backwards by depressing a pedal. The lay-out on a vehicle is shown in Fig. 1, where 1 is the engine, 3 the hydraulic clutch, 5 the gear-box, and 6 an isolating clutch, a two-way clutch which is rendered one-way by depressing a pedal 7. A drum 4 fast on an intervening shaft 9 is stopped and turned backwards on depressing the pedal 7, which is also connected so as to throttle down the engine 1. A boss 12, Fig. 2, projecting from the drum 4 turns inside a sleeve 21 projecting from a cover-plate 20 of the casing of the gearing 11 &c. Free upon sleeve 21 is a plate 23 with a lug 29, Fig. 3, held by a spring-pulled bolt 27 down on a lug 25 of the fixed casing. A brake band 38 encircling drum 4 is pivoted at one end to a pin 40 carried by the plate 23 and is pivoted at the other end to a pin 41 carried by a lever 42 in turn pivoted to the pin 40.. The lever 42 is connected through a linkage 43, 44, 46 to the pedal 7, Fig. 1. The drum 4 normally turns to the right of Fig. 3. When lever 7 is depressed, lever 42 is raised so as to tighten band 38 on drum 4. When drum 4 has been stopped, continued depression of the pedal 7 causes lever 42 to rise bodily, carrying with it the plate 23. This backward angular motion continues until a lug 31 upon plate 23 strikes a fixed stop 30. Toothed gear or clutch 11, Fig. 2, has thus been turned backwards, and the gear change can be freely made. On release of the pedal, the bolt 27 returns plate 23 to the right against stop 25, and the brake is released. A modified arrangement is described comprising a brake of the expanding- segment type. Specification 366,081 is referred to.

Filed: 1963-07-19
Abstract: 1,055,742. Electromechanical delay lines. MULLARD Ltd. July 19, 1963, No. 28704/63. Heading H3U. A solid polygonal delay line of e.g. glass is provided with a non-critical face, i.e. one at which an equal number of positive and negative reflections take place, the sign of a reflection being determined by the number of previous reflections and changing at each successive reflection. At each reflection, lateral inversion of the beam takes place. In the delay line shown, the two reflections from positions 9, 12 on face 3 are of opposite sign since they respectively invert and restore the beam. Error in the angle of this face is automatically compensated. Hence material may be removed from it in order to adjust the delay time.

Title: Improvements in apparatus for the generation of acetylene gas
IPC: C10H15/06
Filed: 1928-10-06
Abstract: 321,784. Haworth, J. Oct. 6, 1928. Feed-openings for solids regulated by gasholders.-An acetylene generator of the kind comprising a casing containing water and a bell floating therein from which is suspended a carbide hopper, the valve of the. hopper being actuated when its stem comes into contact with the bottom of a. water-container the casing, is adapted for the generation of gas at high or low pressure, as desired, by the provision of a separate and detachable chamber adapted to be fitted to the top of the generator, As shown, a bell C floating in a casing A supports a carbide hopper D above a water-container E. The valve c of the hopper D is actuated when its stem c<1> contacts with the bottom of the container E. The generated gas passes through pipes G, g to a box g<1> from which gas at a low pressure can be withdrawn through a tap H. To adapt the apparatus for the generation of gas at a higher pressure, a chamber J is superposed gas-tightly on the casing A, and gas is passed into the chamber J by wav of pipe g<2>, catch-box g<3>, tap g<5>, and pipe a<2>. The catch-box g<3> carries a pressure gauge M, and a safety valve L is provided also. From the catch-box g<3> a pipe g<7> having a non- return valve g<6> leads to a sight-chamber N and a pipe g<9> for withdrawing the gas. In operation, the tap g<5> is opened for a short time so as to permit gas to pass into the chamber J; this causes the descent of the bell C and supply of carbide through the valve c; the gas then generated lifts the bell C and cuts off the carbide supply, and the tap g<5> is then opened again so as to allow gas at increased pressure to enter the chamber J until equilibrium is restored between the chamber J and the ccntainer E. These operations are continued until the desired pressure is attained, whereafter the tap g<5> is closed, and gas at the desired pressure is taken off through the pipe g<9>. The pipe K acts as a reducing or exhausting valve and carries a tap k<1> by which the pressure in the chamber J can be reduced. Specification 291,897 is referred to.

Filed: 1957-09-19
Abstract: <PICT:0866919/III/1> <PICT:0866919/III/2> Coke oven gas is washed in a hydrogen purification plant with liquid nitrogen derived from gaseous nitrogen produced in an associated but substantially separate air separation plant, the gaseous nitrogen being passed, after compression, to the purification plant wherein it is cooled at least partly by heat exchange with cold nitrogen from the washing step, being thereafter passed to the air separation plant wherein it is at least partially liquefied by heat exchange with cold air or a cold air fraction from an intermediate stage of the separation process, and being thereafter returned to the hydrogen purification plant as washing liquid.  As shown in Fig. 1, nitrogen from an associated air separation plant (not shown) is cooled, after compression to 200 atmos. in a compressor 21, in two parallel heat exchangers 22 and 23 by nitrogen from the washing stage, and washed gas, respectively, is expanded through valves 8, is condensed in a further heat exchanger (not shown) by an oxygen-enriched liquid air fraction, and is then passed to washing column 24.  The remaining liquid is vaporized in heat exchanger 27 by crude gas from heat exchanger 25, is further heated in the heat exchanger 22, and leaves the apparatus through line 7.  Crude gas is passed through a line 5 at a pressure of 15 atmos., is cooled in the heat exchanger 25 by washed gas from the column 24, is further cooled in the heat exchanger 27, and is then washed in the column 24.  The washed gas is heated in the two parallel heat exchangers 23 and 25, and leaves the apparatus through line 6 after admixture with nitrogen from compressor 21.  As shown in Fig. 2, nitrogen from an associated air separation plant (not shown) is cooled, after compression to 180 atmos. in a compressor 21, in two parallel heat exchangers 22 and 23, by nitrogen from the washing stage, and nitrogen from the vacuum evaporator 28, respectively, is condensed in a further heat exchanger (not shown) by a cold gaseous air fraction, and is then passed to washing column 24, except for a small proportion which is evaporated in the vacuum evaporator 28, thereby condensing nitrogen from the washed gas, and then passed through heat exchanger 23 and vacuum pump 29.  The liquid remaining after washing is vaporized in heat exchanger 27 by crude gas from parallel heat exchangers 25 and 26 (wherein the crude gas is cooled by heat exchange with washed gas, and vaporized nitrogen from evaporator 27, respectively), is further heated in parallel heat exchangers 22 and 26, and leaves the apparatus through line 7.  Crude gas is passed through a line 5 at a pressure of 30 atmospheres, is cooled in the parallel heat exchangers 25 and 26, is further cooled in the heat exchanger 27, and is then washed in the column 24.  The washed gas is heated in the heat exchanger 25, and leaves the apparatus through line 9 as substantially pure hydrogen, containing e.g. 2% of nitrogen.
