Title: Manufacture of nuclear mono- or di-alkylated aromatic acylsulphonamides, and their p-amino derivatives
IPC: C07C311/45
Filed: 1944-04-07
Abstract: Nuclear mono- or di-alkylated aromatic acylsulphonamides are prepared by treating a nuclear mono- or di-alkylated carboxylic acid amide with a p-nitrobenzene sulphene halide and then oxidizing the product. If desired, the compound may be reduced to form the corresponding p-amino compound.  Aromatic carboxylic acids which may be used as starting materials include 3 : 4-dimethyl-, 4-ethyl-, 4-methyl-, 4-propyl-, 3-methyl-4-ethyl-, 3-methyl-and 3 : 5 - dimethyl - benzoic acids.  In an example, a pyridine solution of 3 : 4-dimethyl benzamide is treated with 4-nitrobenzene sulphene chloride and the reaction product poured into cold hydrochloric acid.  The product is filtered off and dried and oxidized with potassium permanganate in acetone solution to form 4-nitrobenzene-N1-31 : 41-dimethyl-benzoyl)-sulphamide.  This is then reduced to the corresponding p-amino-compound.  The reduction may be carried out by catalytic hydrogenation in the presence of a Raney-nickel catalyst or by means of iron in a weakly acid medium.

Title: Improvements in and connected with automatically locking and unlocking railway carriage doors, and doors of other vehicles
IPC: E05B65/42
Filed: 1924-03-15
Abstract: 235,623. McGhee, G. March 15, 1924. Railway-carriage doors and the like, fastening automatically.-An automatically operated fastening means for the doors of railway coaches is operated through a pair of cams on the running wheels axle, the cams alternately advancing and retracting a pair of pivoted levers carrying weighted fingers which hold the spring-shooting means for the bolts out of action until the speed of rotation of the cams is such that the inertia of the weighted fingers results in their failure to retain the spring shooting-means. Means are provided for operating the bolts on one side of the coach only if desired, and for holding the levers out of contact with the cams for long-distance running. The cams A, A<1> are oppositely mounted on the axle B and alternately advance levers E, E<1> pivoted at D in the bracket C and held in contact with the cams by springs (not shown). The levers E, E<1> are each provided with a finger F, F<1> counterweighted at F<2>. The horizontal part of this advanced finger F holds up a bracket I fixed to the hollow shaft O, while the lever E<1> recedes. The finger F' holds the bracket while the lever E recedes. When the cams are rotating rapidly due to the speed of the train, the inertia of the weights F<2> causes the fingers F, F' to tilt so that they fail to hold up the bracket I which is then rotated by a torsion spring G and with it the shaft 0. In rotating, the shaft 0 engages pins N<1> on loose cranked arms K inserted in the ends of the shaft arms K<1> actuating the bolts H to lock the doors by rods J and cranks R<1>. When the train slows down, the fingers F, F<1> assume the position in which their long parts are again horizontal and engage the bracket I to lift it to a vertical position and allow the bolts H to drop into inoperative position. When it is desired to operate the bolts on one side only of the coach, a cord M is pulled, rocking a lever L to hold the bolts on the other side permanently locked. The slots N in the shaft O permits of the necessary play to allow the bolts of one side to be released while those of the other side remain locked. For long distance running where the constant friction of the cams on the levers would cause undue wear, an arm O<1> turning on a boss P and operated by a cord Q is provided so that the levers can be lifted away from the cams after the bolts have been automatically shot.

Title: Improvements in or relating to installations for straightening and dividing sheet metal strips or bands
IPC: B21D1/02
Filed: 1967-02-13
Abstract: 1,113,548. Metal strip feeds; shearing; straightening. I. UNGERER. 13 Feb., 1967 [20 Aug., 1966], No. 6813/67. Headings B3E and B3W. An installation for straightening and dividing a metal strip 3 comprises a stationary shear 4 and straightening rolls 2 which feed the strip and is characterized in that the rolls are driven by an hydraulic motor which is connected to a fluid pressure pump by two ducts of different cross-sectional areas, the smaller duct supplying pressure fluid to drive the rolls at a low speed and the larger duct combining with the smaller duct to drive the rolls at a higher normal speed. The motor (8), Fig. 2 (not shown), is connected to the pump (7) by large and small ducts each having an associated return line, and each of the four lines containing an electromagnetically operated stop valve (13, 14, 23, 24). The shear 4 is also connected to the pump, through a reversing switch (27). Operation.-With all the valves open, fluid is supplied to the motor (8) through both the large and small ducts to drive the rolls at the normal speed. When the leading end of the strip reaches a first photo-electric cell 5, the valves (13, 14) are closed and shut off the large supply duct and its return line. The small duct continues to supply fluid at 5% of the previous rate, until the leading end of the strip reaches the photo-cell 6 which causes the remaining valves (23, 24) to be shut to stop the rolls and apply a brake. Fluid from the pump (7) then passes to the shear 4. At the end of the shearing cycle the valves (13, 14, 23 and 24) are reopened and the cut-off length of strip is removed by a conveyer. In a modification the valves associated with the large duct are closed when the leading end of the strip reaches a photo-cell downstream of the shear and simultaneously an adjustable time-delay device is started which closes the valves associated with the small duet after a predetermined time interval.

Title: Improvements in fuel supply systems for gas turbine engines
Filed: 1954-03-10
Abstract: 764,071. Gas turbine plant. HOBSON, Ltd., H. M., and GREENLAND, L. S. Feb. 22, 1955 [March 10, 1954], No. 6974/54. Class 110 (3). [Also in Group XXIX] In apparatus for controlling the rotational speed of an aircraft gas turbine engine and of the type comprising an engine - driven pump supplying fuel to the engine, a metering valve for controlling the rate of flow of fuel to the engine, and a governor including speed and acceleration responsive elements for actuating the metering valve to reduce the flow of fuel in response to increase in speed and positive acceleration of the engine and to increase flow of fuel in response to decrease in speed and negative acceleration of the engine, a second metering valve is provided in series with the governor-controlled metering valve and a device responsive to ram pressure actuates the second meeting valve so as to decrease the rate of flow of fuel to the engine in response to decrease in ram pressure and vice versa. The invention is described as applied to a fuel system as described in Specification 764,072 in which fuel is fed to a main centrifugal pump 1 which feeds a secondary pump 2 the output from which is delivered to spill burners 4, and the connection between the two pumps contains the speed and acceleration responsive metering valve 8 and the second valve 9 which is responsive to ram pressure. The valve 8 is positioned by a spring-loaded piston 38 which is governed by a valve 67 actuated by a centrifugal governor in conjunction with an acceleration responsive element 6, the latter consisting of a control valve which governs the pressure applied to a diaphragm 66 and is actuated by relative rotation between a rotary casing 44 and a flywheel 42 which is connected with the casing 44 by spring means. The loading spring of the governor is adjusted by a pilot's control 13 acting through a rotary vane type servomotor, (not shown) on a rack-and-pinion gear 40, 41. The pilot's control also operates fuel cocks as described in Specification 764,072. The valve 9 is also actuated by a spring-loaded piston 33 whose position is governed by a valve member 36 which is actuated by a capsule 54 subject to ram pressure. The pressures acting on piston 33 are also effective on a piston 56 which is connected to the valve member 36. A by-pass (not shown) around the valves 8, 9 contains a minimum flow valve to ensure the flow of sufficient fuel to prevent flame extinction in the event of rapid closure of the valve 8. Specification 677,249 also is referred to in the Provisional Specification.

Title: Improvements in or relating to measuring apparatus
IPC: G01G23/375
Filed: 1957-03-04
Abstract: 842,115. Photo-electric measuring. LEBAR, M. L. March 4, 1957 [March 3, 1956; Feb. 25, 1957], No. 7159/57. Class 40(3). [Also in Group XXXVIII] Measuring apparatus comprises a member angularly displaced by the measurement to rotate another member which produces impulses which are detected photo-electrically and counted electronically, a mechanical movement amplifier being interposed between the measuring member and the rotary member to effect a plurality of revolutions of the latter for one complete travel of the former. A weighing machine beam 1, Fig. 1, is pivoted at 5 along with a lever 4 on which is pivoted another lever 7. At rest, levers 4 and 7 are held together by a permanent magnet to make contacts at their ends. In operation, beam I revolves around its pivot 5 to lower a rod 13 which through a toothed segment 15 and pinion revolves a spindle 16, Fig. 3, of a gear box 22 the input shaft of which is driven by a motor 21. An output shaft 17 which performs one hundred revolutions to every revolution of the shaft 16 carries a perforated disc 20 designed to interrupt the light from a source 18 falling on a photo-electric cell 19. The motor 21 is then started manually and the disc 20, starting from a zero position, turns until the levers 4, 7 regain contact to interrupt the supply of current to the cell 19 and cut off the motor. Since the motor does not stop instantaneously levers 4 and 7 come out of contact to return when the motor is reversed by the breaking of contacts 11, 12, to return the arm 4 to zero position. During the downward movement of the arm 4 the disc 20 revolves to an extent proportional to the weight under measurement allowing a number of impulses of light from the source 18 to fall on the cell 19 through the perforations in the disc 20. The zero position of the disc may be determined by the coincidence of two slots, one on the disc and the other on another co-axial disc driven at a different speed (Fig. 8, not shown, refers). Pulses from the photo-cell are fed to an electronic counter where they may also be registered or printed. A wheel 31, Fig. 11, 1, engages with teeth 33 to position a printing wheel 80. Contact arm 36 wipes studs 37, one of which is energized to represent the numeral. Upon energization an electromagnet 39 clamps the wheel through the action of a pawl 35. When a full sensing sweep has been made a striker 102 prints the numeral. A number of wheels 31 are revolved by a common driving shaft through brass and nylon washers (Fig. 12, not shown). A positive drive may replace friction drive, as described with reference to Fig. 13 (not shown). In another embodiment a plurality of perforated discs driven at different speeds representing various ratios is employed to register cost as well as weight. Applications to liquid fuel dispensers and electrical indicating instruments are also mentioned.
