Title: Method of inhibiting polymerization
IPC: C07C17/42
Filed: 1948-01-26
Abstract: Polymerization of polymerizable vinyl aromatic compounds (e.g styrene, nuclear alkylated styrenes, a -alkylstyrenes, a -alkylhalostyrenes, nuclear chlorinated, especially dichlorinated, styrenes, the compound obtained by dehydrogenation of the nuclear ethyl group of ethyl p-ethylbenzoate, vinyl-naphthalenes and -chloronaphthalenes, divinylbenzenes, and vinyl heterocyclic compounds of aromatic character such as vinylpyridines and vinylthiophenes) is retarded by incorporating therein a small amount (e.g. 0.001 to 5 per cent) of the product obtained by reacting, at reflux temperature and in the presence of a catalytic amount of stannic chloride, a substituted or unsubstituted hydrocarbon chloride (preferably containing 4-12 carbon atoms in the molecule) and a compound of the general formula <FORM:0642612/IV (b)/1> wherein R1, R2 and R3 represent hydrogen, hydroxy or a substituted or unsubstituted hydrocarbon group and R4 and R5 hydrogen or a substituted or unsubstituted hydrocarbon group, provided that at least one of R1 and R3 is hydroxy and at least one nuclear hydrogen atom is present).  The inhibitors may be used individually or in admixture or in conjunction with other inhibitors.  Examples describe the preparation and use of: (1) tert.-butylcatechol (from catechol and tert.-butyl chloride); (2) tert.-butylpyrogallol (from pyrogallol and tert.-butyl chloride); (3) the reaction product of mono - tert. - butylcatechol with tert. - butyl chloride; (4) the reaction product of 2 : 5-dihydroxydiphenyl and tert.-butyl chloride; (5) the reaction product of tert.-butylcatechol and mixed chloroethyldichlorobenzenes. Hydroquinone may be similarly treated, and additional hydrocarbon halides specified are aryl, aralkyl and alicyclic halides, and substitution products thereof containing oxygen, e.g. in the form of a hydroxy group.ALSO:In the distillation of polymerizable vinyl aromatic compounds, especially nuclear dichlorostyrenes, polymerization is retarded or prevented by the addition of a small amount of the product obtained by reacting, at reflux temperature and in the presence of a catalytic amount of stannic chloride, a substituted or unsubstituted hydrocarbon chloride and a compound of the general formula <FORM:0642612/III/1> wherein R1, R2 and R3 represent hydrogen, hydroxy or a substituted or unsubstituted hydrocarbon group and R4 and R5 hydrogen or a substituted or unsubstituted hydrocarbon group, provided that at least one of R1 and R3 is hydroxy and at least one nuclear hydrogen atom is present.  The inhibitors may be used individually or in admixture or in conjunction with other inhibitors, it being frequently advantageous to use two inhibitors, one substantially less volatile than the monomer being distilled and the other slightly more volatile.

Title: Vehicles having load-dependent braking apparatus
Inventor: STONE CYRIL JOHN
IPC: B60T8/18
Filed: 1966-01-20
Abstract: 1,130,823. Fluid-pressure brakes. WEST- ; INGHOUSE BRAKE & SIGNAL CO. Ltd.  8 Dec., 1966 [20 Jan., 1966], No. 2680/66.  Heading F2F.  In a compressed-air braking system for a rail vehicle load-responsive valves 5, 6 associated respectively with axles 1, 2 of the vehicle are of the self-lapping type adapted to give an output pressure between zero and the input pressure in accordance with axle load, and the valves are arranged in series with one another and with a supply reservoir 18 such that the final output at 22, used to modify the braking of the vehicle, is dependent solely on the effect of the valve associated with the lightest-loaded axle. Each valve comprises a diaphragm system 8 which responds to the degree of deflection of the respective axle spring 3 or 4 and also to pressure at outlet 16 to control the movement of exhaust tube 10, which together with spring- loaded inlet valve 12 constitutes a self-lapping valve assembly, whereby a balance between spring deflection and outlet pressure is achieved in all circumstances in the case of valve 5, and in the case of valve 6 is maintained only when axle 2 is the lightest-loaded axle, in which case pressure is progressively reduced in stages by the two valves. When axle 1 is the lightest loaded, all pressure reduction takes place in the valve 5 and valve 6 remains open. The reduced pressure at 22 is fed to a cylinder 24 where it acts on a spring-loaded piston 25 so as to determine the position of a roller 31 carried by a lever 29 pivoted at 30, the roller acting as a fulcrum for a lever 32 through which a control force, obtained from a brake pipe 40 via the usual relay/emergency valve 37 and a pressureresponsive diaphragm, is transmitted to the movable exhaust tube 47 of a self-lapping valve 47, 48, 50 controlling supply of air from the reservoir 18 to brake cylinder 46. As a result, the control force on the self-lapping valve 47, 48, 50 is determined by a combination of brake pipe pressure and loading of the lightest-loaded axle and is continuously variable in accordance with both factors. Alternatively, the arrangement may be modified so that only two variations of braking effort in accordance with load are possible, e.g. by incorporating toggle mechanism between the piston 25 and the roller 31 which would snap over at a predetermined final output pressure at 22 to move the roller 31 from one to the other of two positions.

Title: Improvements in aircraft propeller engine speed controls
Inventor: TUGWOOD BRIAN RICHARD
IPC: H02P5/52
Filed: 1958-01-30
Abstract: 826,329. Automatic speed-control systems. DE HAVILLAND PROPELLERS Ltd. Jan. 30, 1958, No. 3180/58. Class 38 (4). In an aircraft propeller speed control system in which control is effected by control of the engine or the propeller by an engine mounted servomotor, stability of operation is ensured by a device, comprising a pair of interconnected rotors driven by the servomotor and running within a respective pair of stators, which feeds back to a preceding point in the control loop a multiphase signal the frequency of which is proportional to the rate of movement of the servomotor. Lack of synchronism between the slave propeller 12, Fig. 1, driving alternator 11 and the master propeller driving alternator 10 results in the rotation of a soft iron rotor in comparator M1 to which three-phase signals from both alternators are sent, and the generation of a speed error signal in the rotor of synchro M2 which effects control through an amplifier 14 and a trimming actuator 15 acting on the spring loading of a governor controlling the propeller pitch. Servomotor M7, Fig. 2, of the trimming actuator drives a rate generator G1 which returns a stabilizing signal to the amplifier 14, and a pair of rotors R1, R2 in stators S1, S2 the former of which is energized from the aircraft mains over transformer T1, the devices being effective additively to produce a multiphase signal which is returned to the stator of synchro M2. The frequency of the multiphase signal is twice the rotational speed of the servomotor output shaft. A separate phase control loop, including synchros M3 and M4 the latter of which has means for introducing an adjustable phase datum, rotates the stator of synchro M2 in the event of a phase error to introduce a speed error signal whereby the phase error is removed. The output of synchro M4 acts through an integrating amplifier on a servomotor M6, and through a phasesensitive detector circuit and a differentiating circuit on a servomotor M5, the outputs being applied to rotate the stator of synchro M2 through a differential reduction gear.
