Title: Improvements in or relating to a power plant and method of producing steam
IPC: F01K7/22
Filed: 1954-10-05
Abstract: 755,590. Turbines. COMBUSTION ENGINEERING, Inc. Oct. 5, 1954 [Oct. 29, 1953], No. 28634/54. Class 110(3) [Also in Group XIII] In a power plant installation comprising a boiler, including a furnace 10 having steam generating tubes 12 on its walls, and a multi-stage turbine 44 receiving steam from the boiler, a separately fired reheater 52 is disposed adjacent the turbine to reheat steam between the intermediate pressure stage and low pressure stage. Steam from the drum 30 passes through a low temperature section 21 and high temperature section 18 of a super-heater 16 and then through conduit 42 to the high pressure stage of the turbine 44. The exhaust from the high pressure stage passes through conduit 46 back to a reheater 20 in the main boiler and is then conveyed to the intermediate pressure stage of the turbine 44 through conduit 48. The exhaust from the intermediate pressure stage passes through conduit 50 to heat exchanger elements 53 in the separately fired reheater 52 and is thereafter conveyed through conduit 54 to the low pressure stage of the turbine 44. The exhaust from this stage passes through conduit 56 to a condenser or other apparatus. The main boiler furnace 10 is tangentially fired through burners 14, preheated combustion supporting air being conveyed to the burners from an air heater 22 through conduits 26. The reheater 52 has a wind box 65 into which extends a burner 67 and combustion supporting air is introduced under substantial pressure from a fan or blower 58. The inlet to the blower 58 is in communication through conduit 62 with air conduit 26 of the main boiler and with the atmosphere through conduit 60. The air supply is controlled by valves 64. The combustion gases in the reheater 52 are conveyed through duct 76 to the main boiler and are introduced through a branch 80 into the furnace 10 thus controlling the superheat temperature, and through a branch 78 into the boiler between the superheater 16 and air heater 22. The flow through ducts 78 and 80 is controlled by valves 82.

Title: Single lever control for transmission
IPC: F16H63/20
Filed: 1972-06-20
Abstract: 1391854 Change-speed gear MASSEYFERGUSON SERVICES NV 20 June 1972 [21 June 1971 17 Sept 1971] 28739/72 Heading F2D A single shift lever 102 is movable to positions selecting through mechanical linkage amongst eight ratios of a tractor transmission, and also for selecting an equal or lesser number of reverse ratios independently of the speed ratio selection. The lever 102 is guided in a slotted gate 190, having two spaced H slots 182, 184, each providing four ratios, change from one to the other H slot changing a range-selector 72 which doubles the ratios, whilst in any, or only a restricted number of settings, upward movement of the lever 102 causes it to fulcrum against the edge of the gate-slot and select reverse in the particular ratio. Gear arrangement.-A first countershaft 10, driven from an input shaft 6 through a forwardreverse train with FR selector clutch 62, drives an aligned output shaft 4 through a second countershaft 12 at four ratios selected by double clutches 64, 66, the ratios being doubled by a range selector clutch 72, which slides an outputsplined wheel 40 to mesh a wheel 36 for low range L, or clutch a wheel 22 for high range H. The clutch positions for the eight ratios and forward-reverse are indicated at the end of the chain lines. An input driven power-take-off 7, and an equal ratio front axle drive 60 are provided. Selection.-The single shift lever 102 is secured to an outer yoke 112, pivoted at 114 to a forward-reverse selector rod 108, and at 122 to an inner yoke 120, secured to a ratio-selector rod 106, guided for slide and turn movement in a fixed bearing 107 and in the gate plate 190, 191. Fore-and-aft movement of the lever 102 in a central slot 174 joining the two H-gates 182 184, swings the reverse rod 106 idly in a slot 193, and turns the ratio-rod 106, whereby an arm 172 thereon actuates the range-selector clutch-fork 72 to select H or L range at the appropriate end of the slot 174, whereupon the shift lever 102 can be moved in the corresponding H-gate 182 or 184 to select four ratios, 1 to 4 or 5 to 8, selection being performed by up and down movement to align the selector-rod arm 172 with the corresponding shift-rail 152, 154, and gearestablishment by fore-and-aft movement of the shift lever 102 to actuate the selected shift-rail. Whilst in any ratio setting or in only a restricted number of such settings, lifting the shift-lever 102 causes it to fulcrum about the upper edge of the H-slot, thus depressing the reverse rod 108, which, through a bellcrank 136 moves the shift-rail 124 to reverse. Three-position detents are provided at 162, 170 and two position ones at 130, 150. In Figs 5 to 7, not shown, the reverse rod (108a) at its upper end passes concentrically through a hollow tube (106a) forming the ratiorod, and the rear end of the shift-lever 102 actuates an indicator (232) showing the selected direction of travel.

Title: New quinoline derivatives
IPC: C07D401/12
Filed: 1948-11-05
Abstract: Di-quaternary salts of pyrimidylamino-quinolines having trypanodical properties are obtained by treating a pyrimidylamino-quinoline in which either the pyrimidine or the quinoline compound is in the form of a quaternary salt, and may be as described below, with a quaternary salt forming agent, such as methyl iodide, dimethyl sulphate and methyl p-toluene sulphonate.  In the examples the pyrimidine nucleus is substituted in the 2-, 4- (or 6-) position by lower alkylamino, e.g. methyl-, and isopropylamino, or amino-groups, in another of these positions by a lower alkyl radical, e.g. methyl, or amino, or a lower alkylamino group, and is attached to the linking -NH- group at the remaining 2-, 4-(or 6-) positions, while the quinoline nucleus is substituted in the 4-position by an amino- or lower alkylamino-group, e.g. methylamino-, ethylamino-, and further by a lower alkyl group or groups, e.g. 2-methyl, and bears the linking -NH- group in the 6-position.  If the 4-substituent in the quinoline nucleus is not lower alkylamino-, the pyrimidine nucleus must contain a lower alkylamino-group.  The di-quaternary salts described include methiodides, and metho - p - toluene sulphonates, mostly being converted ultimately into the former, from other intermediate quaternary salts, such as the methyl sulphate. Pyrimidylaminoquinolines and their monoquaternary salts used as initial materials, substituted as described, may be obtained by condensing a suitably substituted 6-amino-quinoline or its quaternary salt with a 4-chloro-pyrimidine or its quaternary salt dehydrating the monohydrate obtained if necessary, and replacing the quaternary group if required, e.g. the hydriodides to the methiodides.  4-Methyl and ethyl-amino-6-aminoquinolines are obtained by hydrolysis of the N-acetyl derivatives.  Specification 658,203 is referred to.

Title: Electric timepiece
IPC: G04C3/10
Filed: 1966-06-22
Abstract: 1,128,849. Electric timepieces. OMEGA, LOUIS BRANDT & FRERE S. A. June 28, 1966 [July 8, 1965], No. 28845/66. Heading G3T. An electric timepiece comprises an oscillating lever 10, a pawl 5 attached to the lever and engaging a ratchet wheel 1, a ston pawl 6 for the ratchet wheel and a magnet 19 adapted to disengage the pawls from the ratchet wheel by magnetic attraction. The ratchet wheel 1 functions as a seconds wheel mounted on a shaft 2 which drives a centre wheel (3), Fig.3 (not shown) and an hour wheel (4). The pawl 5 is attached to a spring 7 and the forked end 12 of the lever 10 is oscillated by an eccentric member mounted on a balance wheel shaft (not shown). The pawl 6 is attached to a spring 8, fixed to a sliding stud 14 having an elongated hole so that the position of the pawl may be adjusted by screws 17. As shown in Fig. 1, the magnet 19, having polepieces 20, 21, is pivoted away from the springs 7, 8 due to a stud 27 on a lever 28 engaging a surface 26 of a lever 22. The lever 28 is held in position by its stud 30 engaging a locking slide 32, the position of the slide being controlled by its stud 38 engaging a groove 39 of a winding shaft 40. Attached to the winding shaft 40 is a flexible portion 41 carrying cylinders 42, 43, the cylinder 43 being made of a material such as rubber or plastics. An arm 45 of the lever 28 has a sloping surface 46 which supports the cylinder 42 so that the cylinder 43 is out of contact with an annular rib (44), Fig. 3 (not shown) on the centre wheel (3). When the winding shaft 40 is pulled outwards to a position in which a nose 33 of the slide 32 engages a notch 35 of a locking spring 36, the lever 28 is rotated about its pivot 29 and the stud 27 releases the lever 22 which rotates clockwise under the influence of a spring 25. Thus the polepieces 20, 21 attract the pawls 5, 6 away from the ratchet wheel and the cylinder 43 moves downwards to contact the rib (44) thereby enabling rotation of the shaft 40 to set the timepiece hands. On returning the shaft 40 inwards, the resilience of the spring 7, 8 overcomes the attractive force of the magnet so that the pawls re-engage the ratchet wheel.

Title: Means for testing lubricating oils
IPC: G01N33/28
Filed: 1933-10-19
Abstract: 427,260. Testing efficiency of lubricants. HELMORE, W., and GRIFFITH, A. A., Royal Aircraft Establishment, Farnborough, Hampshire. Oct. 19, 1933, No. 28895. [Class 106 (ii)] Comprises a method of testing lubricating oil by continuously shearing the oil by means of a free piston in a heated sealed cylinder containing a measured quantity of oxygen or other gas and reciprocated relative to the piston, and measuring the friction between cylinder and piston. The cylinder 1 containing a free piston 2 in the form of a ball is attached by pins 3 to the upper ends of levers 4 which are pivoted at their mid length to a reciprocating shaft 6. This cylinder is balanced by a similar cylinder 7, but not fitted with a ball, attached by pins 8 to the lower ends of the levers 4. The shaft 6 is supported in bearings 9 and reciprocated by a crank and link 13, 12. The cylinder may be filled with gas through a needle valve 15, a channel 16 permitting free movement of gas from one end of the cylinder to the other, and the ball and cylinder are lubricated with a small quantity of oil to be tested. Heating chambers 17 surround the cylinders the temperature being indicated by thermometers 18. The rocking of the levers is limited by electrical contacts 19 and a stop 20. One contact 19 is on the lever and the other and the stop 20 are on a yoke 21 fast on the shaft 6. The lever system is slightly overbalanced on the side of the test cylinder. As the reciprocating shaft moves to the right, the contacts 19 are closed, until a point is reached where the reaction of the pivoted system changes sign, when the contacts open and the reaction is transferred to the stop 20. The position of this change depends on the friction acting between the ball 2 and cylinder 1. Connected in series with the contact 19 is a contact breaker 22 operated by rotation of the crank. The contact breaker 22 is arranged to make contact over about quarter of a revolution starting from a point slightly in advance of the earliest point of the right-hand movement of the shaft 6 at which the contacts 19 can break. The time during each revolution in which both sets of contacts 19, 22 are closed depends upon the friction between the ball 2 and cylinder 1, and the onset of gumming is marked by a rapid change in this quantity. The contacts 19, 22 are in series with a source of current 23 a switch 25 and a galvanometer 24. An earth 26 may also be provided. The galvanometer reading indicates the average current and is a measure of the fraction of each revolution during which contacts 19, 22 are closed. Gumming is indicated by a rapid change in reading. In a modification contacts 19, 20 and contact breaker 22 are omitted and electromagnets are attached by a frame to the shaft 6, the polepieces being attached to a spring- restrained lever connected to the lever system. The varying of the air gaps varies an electric circuit.

[Class 40 (iii).] A keyboard transmitter for printing telegraph apparatus comprises a key for each signal, contacts being operated selectively by the keys to connect simultaneously to the line a code combination of alternating currents of different frequencies taken one or more at a time representing the signal to be transmitted. The transmitter may act as a receiver, each key having a solenoid S, which is selectively energized [Fig. 3 (not shown)]. The transmitting contacts are operated by a key lever K, Fig. 1, operating typewriter mechanism, and having an insulating wedge W, cut so as to operate six contact springs Pi .. P6, P1 making contact last. The contacts P2 .. P6 actuate five relays R1 .. R5, Fig. 2, which connect to the line a combination from the five frequencies ; contact P1 actuates a slow-acting relay R6 which breaks the circuit of relays R1 .. R5. The two stations, A, B, each has a send-receive switch SW, that for A being in the transmitting, and for B in the receiving position. Relays V1 .. V5, tuned to the respective frequencies, are connected across the line and actuate relays X1.. X5, the contacts A .. K of which select the solenoid to be operated, in accordance with Fig. 3 (not shown), thus printing the required letter. The frequencies, which should be within voice frequency range so that long telephone lines may be used, may be produced by commutators ; in this case relays R1 .. R5 may be removed, contacts P2 ..

Abstract: 1,172,869. Uses of photochromism. HAWKER SIDDELEY DYNAMICS Ltd. 28 June, 1967 [29 June, 1966], No. 29298/66. Heading C4S. [Also in Division G2] A coherent light source L is focused at L<SP>1</SP> in a plane F containing a filter plate P, and transparency P 1  is introduced in the light path to produce a diffraction pattern on the plate P. Simultaneously a second coherent light source 5 images a diffraction pattern of a second transparency P 2  on the plate P, and a direct beam E from the source S interferes with the second diffraction pattern to form a hologram. The plate P is made of a photochromic material excited by the frequency of the second source S, so the plate P will be rendered less transparent in certain areas depending on the hologram pattern. The plate P thus acts as a spatial filter for the diffraction pattern of the transparency P 1 . The hologram may alternatively be made by the single beam method.
