Title: Process for the preparation of dibenz (b.f) azepines
IPC: C07D219/02
Filed: 1960-12-12
Abstract: The invention comprises compounds of general formula <FORM:0908615/IV (b)/1> in which X is chloro or trifluoromethyl and Y is hydrogen, chloro p  or trifluoromethyl, and the conversion thereof, and of similar compounds in which X and Y are both hydrogen, into 5H-dibenz[b,f]azepines of general formula <FORM:0908615/IV (b)/2> and 10,11-dihydro-5H-dibenz[b,f]azepines of general formula <FORM:0908615/IV (b)/3> (in both of which formula X and Y represent hydrogen, chloro or trifluoromethyl) by dehydration with phosphorus pentoxide, followed, in the latter case, by catalytic hydrogenation. 3-Chloro-9-cyanoacridine is prepared by reaction of sodium cyanide with 3,9-dichloroacridine, is converted by partial acid hydrolysis into 9-aminocarbonyl-3-chloroacridine, reaction of which with nitrous acid gives 9-carboxy-3-chloroacridine, which on reaction with thionyl chloride gives 9-chlorocarbonyl - 3 - chloroacridine, which on treatment with ethanol gives 3-chloro-9-ethoxycarbonylacridine, and this, on reduction with lithium aluminium hydride gives 3-chloro-9-hydroxymethylacridine.  9-Methyl-3-trifluoromethylacridine is prepared from 3-trifluoromethyl-diphenylamine by treatment with acetic anhydride and zinc chloride followed by heating with hydrochloric acid, or from 9-chloro - 3 - trifluoromethylacridine by reaction with diethyl sodiomalonate followed by treatment with acid. Reaction of 9-methyl-3-trifluoromethylacridine with N-bromosuccinimide in the presence of benzoyl peroxide yields 9-bromomethyl-3-trifluoromethylacridine, reaction of which with potassium acetate gives 9-acetoxymethyl-3-trifluoromethylacridine and this on reduction with lithium aluminium hydride gives 9-hydroxymethyl-3-trifluoromethylacridine. 6-Chloro-9-hydroxymethyl-3-trifluoromethylacridine is prepared by a similar series of reactions from 6,9-dichloro-3-trifluoromethylacridine.

Title: Improvements in elastic-fluid turbines
IPC: F01D17/18
Filed: 1962-11-15
Abstract: 1,015,174. Steam turbines; power-generating systems. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). Nov. 15, 1962 [Nov. 17, 1961], No. 43287/62. Headings F1Q and F1T. An elastic-fluid turbine, having a rotor with two bladed wheels for the first stage expansion, has separate inlets arranged to supply separate flows respectively to the two wheels, and a common passage arranged to receive the elastic-fluid from both wheels and direct it towards the inlet of a subsequent bladed wheel stage of the rotor. In an auxiliary steam turbine 1, for driving a boiler feed pump (not shown) of an electrical generating plant having an alternator driven by a main steam turbine (not shown), the rotor 2 has two first stage wheels 5 and 6 provided with inlet nozzle rings 3A and 4A respectively. The nozzle ring 3A is split into two segments angularly occupying approximately 240 degrees and 120 degrees respectively. During normal operation of the main steam turbine, primary steam, which is generally extracted partially expanded from a suitable point in the main turbine, is fed through an inlet 3, a control valve 8, Fig. 2 (not shown), and the larger segment of the nozzle ring 3A to the wheel 5 of the auxiliary turbine 1. When the load on the main turbine is reduced, a valve 10, Fig. 2 (not shown), is opened to admit additional quantities of primary steam to the auxiliary turbine 1 through the smaller segment of the nozzle ring 3A. Below half-load on the main turbine, secondary steam, at a higher pressure than the primary steam and comprising either live steam, desuperheated or not, or partially expanded steam from the main turbine, is admitted through an inlet 4, a control valve 12, Fig. 3 (not shown), and the nozzle ring 4A to the wheel 6. The steam exhausted from the wheel 6 flows in the direction of arrows 14 to join the steam exhausted from the wheel 5, the combined flow passing through stages 16 and 18 and other stages (not shown). Extraction points 15 and 17 and others (not shown) are provided. Steam extracted through point 15 is fed to a feed-water heater. One of the two wheels may be associated with an additional wheel or wheels supplied by the same source. The invention may be applied to the turbine of a turbine-alternator set, in which case the extraction points 15, 17 are omitted, the first-stage wheels 5 and 6 are of nearly equal diameters, the nozzle ring 3A may be divided into three segments and at full-load all the valves are open to admit live steam to the nozzles of both wheels.

Abstract: 1,046,860. Brake transmitting mechanisms. SVENSKA A.B. BROMSREGULATOR. Oct. 12, 1965, No. 43328/65. Heading F2E. Railway vehicle brake rigging of the type that can be set for exerting by power either a higher or a lower braking effort to suit the vehicle load is provided with means operable to manually apply the brake with a leverage independent of whether the rigging is set for the higher or lower effort power braking. The rigging comprises live and dead levers 4, 5 each connected at one end to power cylinder 1 and at the other to the transmission rod of a respective set of wheel brakes for wheels 19, 19A. Lost motion rods 6, 7 connect the levers 4, 5 and a movable block 8 may be swung down between parts 9 and 10 to eliminate the lost motion in rod 6 when lower power braking is required. The hand or foot operable lever 20, which normally rests against a stop or detent 33 is connected to a lever 25 pivoted at 28 to the transmission rod 12. A lost motion connection 22 permits the brakes to operate under power without moving lever 20. When the latter is moved clockwise the lower end of lever 25 moves the rod 12 leftwards, the linkage 27, 7, and automatic adjuster 11A moving the transmission rod 11 rightwards, thus applying the brakes to both wheels independently of the position of block 8. A detent may be provided to hold the lever 20 in this brake applied position. The hand operated member may be of the screw type and the wheel brakes may be disc brakes.

A system for automatically controlling the temperature of a semiconductor material in the melt drawing of rods thereof comprises anticipatory means for restoring the voltage applied to the melting apparatus should this voltage tend to change. A rod 51 of semi-conductor material is drawn from a susceptor 52 wherein the material is melted by means of induction heating by a work coil 53 supplied from a high frequency generator 54 which includes a resonating capacitor 55. The temperature of the material is detected by a thermopile or bolometer 56 producing a voltage which is applied to a self-balancing potentiometer 57, wherein is set the desired temperature, so as to produce a temperature error voltage. This error voltage is applied by way of a high gain, high impedance amplifier 58 and a magnetic amplifier 59 to a saturable reactor 60 so as to control the supply to the high frequency generator 54 and thus the output of the work coil 53. The anticipatory circuit comprises a capacitive potential divider 61, 62 for measuring the work coil voltage followed by a rectifier 63 and cathode follower 64, the output which is applied to the amplifier 58 wherein it is added to the error voltage from the self-balancing potentiometer 57 to provide a further, faster, control over the output of the work coil 53.

Abstract: 1,091,266. Reciprocating and rotary motors; insulation; adjustable cores. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 30, 1966 [Oct. 4, 1965], No. 43827/66. Heading H2A. An electric motor comprises a rotor having two poles, means supporting the rotor for rotary and axial movements, a stator having two fields, one spaced axially from and at a radial angle relative to the other, the poles of the rotor being of an axial length such that when it extends across one of the fields it extends partially across the other, and means to energize the fields alternately to cause the rotor to rotate and reciprocate simultaneously. As shown, one stator field comprises a pair of diametrically-opposite pole members 5, 6, with coils 5a, 6a, respectively; the other comprises another pair of diametrically-opposite pole members (only one, 9, shown), in quadrature arrangement with respect to the first pair and axially-spaced therefrom. The rotor 13 includes a permanent magnet having two curved pole faces 17, and extends from the remote end of one pair of stator poles to the middle of the second pair. In operation, a positive pulse is first applied to the coils of the first stator field, whereupon the rotor rotates from a random position into alignment with it. Next, this pulse is terminated, and a positive pulse is applied to the second stator field; this pulse serves both to rotate the rotor through 90 degrees and to draw it axially to the chain-line position of the Figure. Thirdly, a positive pulse is applied to the first stator field, serving both to rotate the rotor through a further 90 degrees and to draw it axially back to the solid-line position. Fourthly, a negative pulse is applied to the second stator field to rotate the rotor and draw it to the right once more. Thus the rotor simultaneously rotates and reciprocates. The speed of the rotor may be varied by varying the number of pulses per second; when the rotor is up to speed, certain of the pulses may be omitted to change the rate of reciprocation but maintain a smooth rotation. The number of poles per stator field may be greater than two. A.C. may be applied instead of distinct pulses. By changing pulse amplitude the force of reciprocation may be varied. The peripheral spaces between the pole faces of the rotor and between the pole members of the stator, respectively, are filled with epoxy resin.

A building comprising an inner zone constituting a cooling load and an outer zone constituting a heating or cooling load is air conditioned by supplying air to the inner zone and circulating air withdrawn from the inner zone in the outer zone. As illustrated, the inner zone 11 is separated from the outer zone 12 by a corridor 13 on each floor and partitions 16 and 18 divide the zones into rooms 17 and 22. A hollow ceiling (26), Fig. 2 (not shown), extends on each floor above both the inner and outer zones and has openings 67 through which warm air from the zones rises. A duct 55 extending vertically through the building withdraws air from the hollow coiling (26), the air being mixed with fresh air from a duct 54 and then passed through a conditioning unit 33 containing a heat exchange coil 60 to a duct 59 extending vertically through the building. A branch duct 64 on each floor supplies air from the duct 59 to diffusers 66 extending through the ceiling of the inner zone. Air is also withdrawn from the hollow ceiling (26) through downdraught units 70 each including a pair of centrifugal fans 75, 75a, a removable filter 83, Fig. 3 (not shown), and a heat transfer coil 74. Air from the downdraught units 70 is supplied to the outer zone through horizontal ducts 72 provided with outlet openings 73. The coils 60 and 74 are supplied with water from a three-pipe system having a hot water line 41, a chilled water line 42 and a return line 44. Valves 63 and 77 determine whether hot or chilled water or a mixture of the two is supplied to the coils 60 and 74. A pump 45 forces water from the return line 44 through a shell and tube evaporator 38 to the chilled water line 42 and through a shell and tube condenser 37 and a steam heater 32 to the hot water line 41. The evaporator 38 and condenser 37 form part of a compressioncondensation refrigeration circuit. The heater 32 is fed with steam under control of a valve 79 for use when the condenser 37 is insufficient for the heating requirements of the building. A closed circuit 46 including a pump 48 passes water through the condenser 37 and a cooling tower 34 when it is required to dissipate heat from the building. In a modification, Fig. 5 (not shown), the heat transfer coils 74 are arranged horizontally between the fans 75 and 75a and the horizontal ducts 72, and in a further modification (not shown) the units 70 are replaced by downdraught induction units.
