Title: A process for the preparation of di-phenyl ethylene derivatives
IPC: C07C43/205
Filed: 1939-12-18
Abstract: 537,976. Di-phenyl ethane derivatives. CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA, R. T. (DR. KERESZTY & DR. WOLF). Dec. 18, 1939, Nos. 32421 and 32422. Convention dates, Jan. 5 and Feb. 7. [Class 2 (iii)] Diphenylethane derivatives having oestrogenic activity are prepared by subjecting compounds of the general formula where X may be hydrogen alkyl or aralkyl, and where the benzene ring may be further substituted to the action of an alkyl magnesium halide to produce an alcohol of the formula which is then dehydrated to produce the ethylene compound. This dehydration may be carried out by direct removal of water such as by using an alcoholic solution of a hydrogen halide or by replacing the hydroxyl group by chlorine by the action of phosphorus halogenides followed by removal of hydrogen halide. The first method of dehydration involves little or no migration of the benzene nuclei and the product obtained accordingly consists almost entirely of α-α di-alkyl-##-diaryl ethylene. The second method of dehydration particularly when phosphorus oxy-chloride is used, involves considerable migration to give a considerable amount of α#-di-alkyl-α#-diaryl ethylene. If desired the ethylene compound may be subjected to a desalkylation treatment with alcoholic alkali solution at . elevated temperature. Phosphorus pentabromide may also be used instead of phosphorus oxychloride as halogenating agent in the second method of dehydration. The withdrawal of hydrogen halide may be effected by means of alcoholic alkali, or with a tertiary amine such as pyridine or by boiling in a solvent such as toluene above 100‹ C. In the preferred form of the invention the starting material is chlorodesoxyarisoin or another halogeno-desoxy anisoin. These compounds may be obtained by the action of phosphorus halogenides on the benzoins. As alkyl magnesium halides, methyl magnesium bromide and iodide, ethyl-, propyl-, and isoamyl-magnesium bromides may be used. In an example chloro-desoxy anisoin is added to an ethereal solution of ethyl magnesium bromide to give αα-diethyl-##-dianisylethanol which is then dehydrated by heating with dilute sulphuric acid at 70‹-95‹ C. under 0.001 mm. pressure to form αα-diethyl-##- dianisyl ethylene. The dehydration may also be carried out by heating the ethanol with phosphorus oxychloride and boiling the halogenide with toluene. In this case considerable migration takes place to give α#-diethyl-α#- dianisyl ethylene. Another method for carrying out the dehydration with migration is to treat the ethanol with phosphorus pentabromide and then to remove hydrogen halide with either alcoholic potassium hydroxide or pyridine.

Title: Improvements relating to turbo-propeller engine fuel control
IPC: B64C11/30
Filed: 1960-09-22
Abstract: 911,021. Fluid-pressure servomotor-control systems. GENERAL MOTORS CORPORATION. Sept. 22, 1960 [Sept. 23, 1959], No. 32581/60. Class 135. [Also in Group XXVI] A turbo-prop power plant comprises a fourblade variable pitch feathering propeller P, Fig. 1, driven by a gas-turbine E. The pitch-setting ring 16 is connected by the linkage shown to the output member of a co-ordinating mechanism 24 having two manually-operable input members comprising a condition control lever 27 and a power control lever 28. Fuel is supplied to the engine via conduit 47, Fig. 2, pump 48, conduit 49, metering valve 50, cut-off valve 52 and conduit 53. The piston valve member 56 of the metering valve is controlled by a computer 58 which receives governor and turbine temperature setting signals and signals corresponding to engine-operating parameters such as temperature, pressure and speed. The lever 28, Fig. 1, is connected to a rod 103, Fig. 2, the end 123 of which normally abuts the head 122 of a propeller control member 120. The rod 103 carries cams 99, 101 which impart governor and temperature settings to the computer 58 via linkages 97, 94, 92 and 98, 96, 93, respectively. The lever 27, Fig. 1, is connected to a rod 106, Fig. 2, which has an arm 124 below the head 122 of the propeller control member 120. The rod 106 carries cams 107, 108 which respectively control the spring- loading of a pilot valve 70 and the cut-off valve 52. The pilot valve 70 controls a pump by-pass valve 60 by varying the pressure to which the piston valve member 62 is subject. In a multi-engined aircraft the several levers 28 receive the same propeller governor setting but the engines may not be operating at the same power levels. The trim control effected by the condition control lever overcomes this disadvantage. Normally, i.e. up to the feathering position, the power control lever determines the mode of operation of the propeller and engine. In the first 35% of its movement the lever 27 adjusts the loading spring 82 of the pilot valve 70 so varying the power output of the engine to a limited extent by varying the head across the metering valve 50. In the next part of its movement the lever 27 closes the cut-off valve 52 and if the lever 27 is moved further the arm 124 adjusts the propeller control lever 120. Specification 713,155 is referred to.

The elements 4 consist of curved wedge-shaped pieces of iron mounted on non-magnetic arms 13 at radii such as to bring them above the inwardlypointing pairs of pole-pieces 8 of the vertical series of U-shaped magnets, the coils 9 of which are connected to pairs of insulated flexible contacts 16 on the distributor. The contacts are connected to the input leads 18 through slip-rings 17 and are closed, so as to energize the magnets, until such times as they are opened by a stationary insulating projection 21. The top pole-pieces 8<a> energize wound armatures 22 which supply generated current to slip-rings 28 or to a commutator and slip-rings. In an alternative, form, several pairs of magnet columns of the type shown are arranged radially around a circle so that each attracted element is acted upon several times during the revolution. The distributor may be arranged to energize the magnet coils in series or parallel. One of the Provisional Specifications describes also the following : -The coils may be mounted on the rotor for cooperation with stationary attraction members. The current in the coils of either stator or rotor may be controlled by brushes and a cam device such that the coils are short-circuited prior to being de-energized, a resistance being put into the circuit while the coils are short-circuited. The distributor may consist of a circular member of insulating material rotating with the framing and carrying two pairs of contact plates, one pair being connected to the ends of one coil and the other pair to the ends of the second coil. Spring-actuated brushes carried by a stationary part of the machine co-operate with the contact plates and are connected to the supply terminals. A cam device on the circular member raises the brushes to short-circuit the coils and insert resistances in circuit at intervals. Another form of the machine may consist of a drum or frame carrying two outside dynamo stator magnets and a middle motor stator. The motor member is of the attracted iron type and carries brushes which co-operate with the dynamo stators.

Abstract: 1,009,496. Valves. E. K. KINTNER, and E. L. WELLER, [trading as KINWELL DEVELOPMENT CO.]. Aug. 24, 1962, No. 32699/62. Heading F2Y. A valve 5, Fig. 1, for controlling the flow of a liquid is actuated by a pneumatic piston 9 and has a body comprising two parts 1, 10 detachably clamped together at 15, a closure wall 14 being interposed between the parts and having sealing rings 14a, 14b and the piston being connected with the valve by a telescopic stem providing no direct leakage path between the two parts of the body. Contamination of a liquid, such as milk, controlled by the valve due to leakage of the fluid for actuating the piston 9 is thus avoided. The stem 8 connects the piston with the valve stem 6 through a pin 7 and slidably engages the part 10 and a tubular member fixed to the wall 14 through seals 8a and 10a. Failure of any of the seals permits leakage to atmosphere and not between the two parts of the body. The clamp 15 may be of the type contracted by a thumb screw and enables the part 1, which is of stainless steel, to be detached for cleaning. A solenoid-actuated valve may control the fluid supply to the piston 9. In Fig. 4, separate valves 20 control outlet ports 24, 25 supplied by a common inlet port 23. Rounded corners 23a on the ports prevent excessive wear on sealing rings 20a carried by the valves. One of the parts 10 may be replaced by a closure member when two-way operation is required.

Abstract: 499,912. Coin - actuated ticket - delivery apparatus. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and DOLMAN, H. J. Nov. 29, 1937, No. 32839. [Class 27] In a coin-actuated ticket-delivery machine operable either by coins of high or low denominations, the low denomination coins being moved by a power driven member past a control device to actuate the ticketdelivery machine and being subsequently directed to a storage magazine to provide change when a high denomination coin is used, in which case change as well as a ticket is delivered, means are provided that may be brought into action to prevent actuation of the ticket delivery apparatus when coins of low denomination are fed by the power driven member towards the storage magazines so that this member can be utilized to replenish the storage magazines. A ticket strip 1 is fed over a roller 2 between printing and delivery rolls 3, 4 and through a delivery orifice 5 when a solenoid 19 is energized to withdraw a blocking lever 16 from the tail 14 of a pawl 12 which is then moved by a compression spring 13 into engagement with a ratchet wheel 10 on a continuously driven shaft. The pawl is carried by a disc S which is thus carried round through one revolution and through a roller 7 drives the rolls 3, 4 to print and deliver a ticket. Low denomination coins are inserted in an orifice 21 and carried round by a power driven disc 22 past a control device 23 and pass by a shoot 24 to a storage magazine 25. The control device is as described in Specification 320,613, [Class 27], and includes a lever 30 which is rocked to close momentarily the circuit of the solenoid 19 each time coins amounting to the value of a ticket have passed. When an attendant desires to replenish the magazine 25, the door 6 of the ticket-delivery machine is opened to allow a bar 35 to be slid to the left by a spring 36. The bar actuates a bell-crank lever 31 to bring one arm 38 into position to block the tail 14 of the pawl 12. This prevents a ticket from being delivered while coins are being fed by the disc 22 past the control device 23 to the magazine 25.

[Class 38 (iii).] Regenerative braking; field and armature control.-The transition from series to parallel of compound-wound traction motors, the shunt fields of which are arranged to be connected in series, is effected by first reducing the back E.M.F. of a number of the motors (one half in the case of an even number), then, after disconnecting them from the circuit, increasing their back E.M.F. to approximately the full line voltage, and finally connecting them across the line, while the reverse transition is effected by disconnecting the same motors, reducing their back E.M.F., short-circuiting them on to resistances, and then arranging them in series with the remaining motors acting as generators, and finally re-establishing their back E.M.F. At the end of the series controlling positions for motors I, II, the shunt field 5<1> of the motor I is short-circuited as shown in Fig. 2. It is then disconnected altogether, and the armature and series field of the motor I is connected across the series resistance 2<1>, 2<2>, Fig. 4. The following changes of connections are then made:- The armature of the motor I is disconnected from the series circuit, its shunt field is reconnected, and the armature is connected across the supply, Fig. 8. Finally the series resistance is removed. For the reverse transition with regenerative braking, the same changes of connections are made in the reverse order.
