Title: Improvements relating to the preparation and burning of moisture-containing solid fuel and to apparatus for preparing and burning such fuel
IPC: F23C99/00
Filed: 1954-07-05
Abstract: 756,803. Steam generator furnaces. BABCOCK & WILCOX, Ltd. July 5, 1954 [July 7, 1953 ; July 9,1953], No. 19610/54. Class 51(1). In a steam generator furnace fired by fuel containing a high proportion of moisture, e.g. brown coal, the fuel is pulverized in a grinding mill in which it is also dried by hot gases from the furnace, the arrangement being such that as the rate of firing of the furnace is varied over a range extending from a maximum value so is the final moisture content of the fuel changed so that the percentage of moisture in the fuel varies in the same sense as the rate of firing. In the construction shown in Fig. 1, the furnace comprises a combustion chamber 1 communicating through a throat 3 with an antechamber 4, both chambers being lined with cooling tubes connected into the boiler circulation system. The antechamber 4 is divided by vertical tube walls into three compartments having separate outlets to the combustion chamber 1 and separate slag outlets 20 which discharge through shafts 23 into a water trough 25 fitted with a scraper conveyer 26. At each side of the furnace is arranged a beater mill 30 fed with fuel from a hopper 27 through a shaft 29, the mill acting as a fan to draw hot gases from the furnace through aperture 31 and conduit 32. The aperture 31 is fitted with a control damper and the conduit 32 has an air inlet 37 provided with a damper 38 for controlling the admission of tempering air. The mill 30 is connected by pipes 42 to three centrifugal separators 43 each delivering the separated fuel through a burner nozzle 52 to one of the-compartments of the antechamber 4 ; gases and vapours with such fuel as is unseparated pass from the separators 43 through ducting 47 to burners 48 disposed in the wall of the combustion chamber 1. Treated air for combustion is supplied to the burners 48, 52 from a hot air duct 44. The hot air, in its passage to the burners 52, heats the separators 43 so that condensation therein is avoided and the degree of separation effected in each separator is controlled by supplying, through a nozzle 46<SP>1</SP>, agitating air the flow of which may be varied by operating a valve 45. The Specification also describes an automatic system applied to a plant in which the whole of the fuel is supplied to a cyclone furnace arranged to deliver to a secondary combustion chamber leading to the main radiation chamber of the steam generator.

Title: Process for the resolution of racemic threo-1-phenyl-2-amino-1,3-propanediol
Inventor: D AMATO VITANGELO
Filed: 1953-07-15
Abstract: Resolution of racemic threo - 1 - phenyl - 2 - amino-1 : 3-propanediol into its optically active isomers is effected by reacting it with D-glutamic acid in an aliphatic alcohol containing 1-6 carbon atoms in the molecule, separating by filtration the insoluble material from which (+) - threo - 1 - phenyl - 2 - amino - 1 : 3 - propanediol is regenerated by treatment with a concentrated aqueous alkali metal carbonate solution and recrystallization from an inert organic solvent, evaporating to dryness the aliphatic alcohol solution and recrystallizing the residue from an inert organic solvent to obtain (-) - threo - 1 - phenyl - 2 - amino - 1 : 3 - propanediol.  The latter remains uncombined with the D-glutamic acid, of which, nevertheless, the optimum quantity is two equivalents per equivalent of racemic aminodiol.  In an example the alcohol used is ethanol, the alkali metal carbonate is potassium carbonate and the inert organic solvent is chloroform.

Title: Improvements relating to the control of internal-combustionengines or other prime movers
IPC: B61C17/12
Filed: 1926-08-13
Abstract: 278,841. British Thomson-Houston Co., Ltd., and Collingham, R. H. Aug. 13, 1926. Centrifugal governors; maintaining speeds equal.-The power output of one or more internal combustion engines or other prime movers such as installed on coaches a, b &c. of a train is regulated by adjusting the setting of the centrifugal governors 11<a> by operating a fluid pressure system on each motor through a hand-controlled pressure or vacuum system linking all the coaches. To operate all the primes movers from coach a. the valves 35<b> and 39 leading from the air pressure reservoirs 34 are closed while valve 35a is open. To increase speed the driver operates handle 41a thus increasing the air leak through valve 39 and reducing the pressure in pipe 32 and in the train pipe c. This allows spring 31<a> to move piston 28a down and so operating the valves 22a of the oil pressure system to open the ports 21<a> at the lower ends of cylinders 19<a>. Oil from the pumps 24a forces piston 18<a> up which by causing the floating levers 26<a> to pivot about their points of connection with the piston 28<a> effects the closure of the lower parts 21<a> in due course. Meanwhile the upward movement of piston 18<a> by rotating the levers 15a has depressed the spring 14a to increase the loading on the governor 11<a>. The compressed air in the connecting pipe c operates a similar governor arrangement &c. in the coach b and so on for any number of coaches. By initially adjusting the springs 31<a> of the servo motors for the different prime movers, simultaneous regulation of each prime mover is obtained.

Title: Pattern catching
Inventor: BARDWELL FRANCIS GREGORY
IPC: B23Q35/14
Filed: 1970-04-27
Abstract: 1,248,384. Template followers. STEWARTWARNER CORP. April 27, 1970 [April 28, 1969], No.20041/70. Heading G3N. [Also in Division G1] A pattern contour trailing system, incorporating a rotatable pattern sensing head, is provided with a detector reaching a desired position in relation to the contour to permit operation of an automatic device for rotating the head. As shown, a pattern sensing head 10 is rotated by a steering mechanism 12 and travels along the template at a speed determined by a drive unit 14. During a following operation the output of a scanning photo-cell 16 is fed through a line or edge-following selector circuit 18 to a pre-amplifier 20. The output of the pre-amplifier comprises fundamental and first harmonic components which are fed through a gated amplifier 26 to a drive amplifier 22 controlling a steering motor 24. To initiate a following operation the head 10 is pointed toward a line or edge and a switch 56 is closed. The preamplifier output is fed to a circuit 32 which receives the zero signal indicating that the photo-cell is off the pattern and maintains a trigger circuit 50 so that it has an output A to hold closed an AND gate 52. The momentary closure of the switch 56 has set a flip-flop 58 whereby a signal F is fed through an OR gate 54 to actuate a relay drive 34 and close a relay contact 34a so that a feed motor 28 is supplied from a unit 30. When the head approaches the line or edge the fundamental 60hz component increases and is passed, through a filter 62 and an amplifier 64, to enable an AND-gate 60 at a level B1 in conjunction with a fixed potential, for edgefollowing or the A function, for line-following, as set by a switch 18a. The increase in the fundamental and first harmonic components is detected by the circuit 32, the output of which switches circuit 50 to the A condition. The gated A. B1 signal sets a memory 70, which had been previously reset by closure of switch 56. As the head moves closer to the line, or edge, the fundamental component rises to a level B2, which is inverted by an inverter 66 to a signal #B2. The signal #B2, A and Q, from memory 70, enable an AND-gate 68 and reset the flip-flop 58 whereby the F signal becomes zero and a F signal rises to one. The A-F signals enable the gate 52 and a A. F signal is applied to open the gated amplifier 26 to permit the sensing head 10 output to control the steering mechanism 12. The steering mechanism then turns the sensing head to approach the line or edge to be followed without overshoot.

Abstract: 357,290. Road vehicle suspensions. FERRARIS, A., 38, Princes Park Avenue, Golders Green, London, and SERVE, A. J., Chez Nous, Bassetsbury Lane, High Wycombe, Buckinghamshire. July 2, 1930, No. 20046. [Class 79 (iv).] In six-wheeled motor vehicles having two rear axles connected by inverted equalizing springs the links or shackles connecting the ends of the springs to the axles are rigid with the brake drums, and the brake torque reaction is resisted by radius or torque rods. The forward end of the spring 9 is connected by a shackle 9a to the forward axle 4 which is connected to the frame by radius rods 20 having spherical connections at one end and adapted to take the braking torque and the longitudinal reactions. The rearward end of the spring-9 is connected to a shackle 9a, 13 pivoted to the axle, the upper end being connected to a radius rod 12, the forward end of which is connected by a spherical joint to a projection 10 from the main supporting bracket 1. The link 12 and the rear half of the spring 9 constitute in effect a parallel linkwork which resists the braking reactions. The brake-operating members 17, 22 are connected to the frame in the neighbourhood of the pivots of the radius rods so that the up-and-down movements of the axles do not effect the operation of the brakes.

Abstract: 1312802 IGFETs KOGYO GIJUTSUIN 27 April 1970 [20 Nov 1969] 20131/70 Heading H1K The gate insulation of an IGFET is protected against overvoltages of both polarities by an arrangement of a pair of PN junctions or a PN junction and Schottky barrier connected backto-back and sharing a common zone which is more highly doped than the region or regions with which it forms a PN junction. The arrangement which is such that bipolar transistor action across the common zone is minimized is connected between the gate and the substrate in which both the IGFET and the arrangement are formed. In the Fig. 3 arrangement a diffusion is used to form the nested annular zones 3, 2a. Zone 3 is the source and the channel is formed in zone 2a beneath the gate electrode at 4. Connection is made to region 2a and hence to substrate 200 via diffused region 2d. Protective diodes are constituted by the junctions between zones 5P and 1P, and zone 1P and the substrate respectively. Minority carrier injection is avoided by doping epitaxial layer 1P more heavily than the substrate and zone 5P which is therefore preferably grown epitaxially. Alternatively zone 5P is dispensed with, in which ease electrode 5 forms a Schottky barrier with zone 1P. In another embodiment, Fig. 5, in which the gate is in a groove, protection is provided by Schottky barrier 55 and the PN junction between zone 2P and the substrate which here forms the drain.
