Title: Improvements in or relating to Internal Combustion Engines.
Inventor: PRICE WILLIAM TUDOR
IPC: F02B19/14
Filed: 1918-12-04
Abstract: 121,470. Price, W. T. Dec. 10, 1917, [Convention date]. Regulating. - In an engine in which the main portion of each charge of liquid fuel is introduced into air in the cylinder during the compression stroke and ignition is effected by the compression of combustible mixture thus formed, fuel injection nozzles 27, which impart a whirling motion to the fuel, are disposed on opposite sides of a waterjacketed combustion chamber so that their streams converge and meet along the axis of the cylinder. The combustion space may be formed in a head x which is separate from a cover y in which are housed an air-inlet valve 1, an exhaust valve 2, and a sparking-plug 21, the air-inlet passage being controlled by a hand-actuated throttle valve 35. The combustion chamber has conical portions 23 which open into a central part of circular crosssection, the parts 23 being cut away at 24 to facilitate the opening of the air and exhaust valves. Fuel is supplied by a pump, Fig. 8, actuated by an adjustable carn 8, the return or suction stroke being effected by a spring and limited by an adjustable stop 34. A member 5<a> cnables the pump to be actuated by hand. Excess fuel delivered by the pump is returned through a by-pass pipe 10 in which is located a mechanicallyactuated valve 11 controlled by a governor. The valve is opened during the delivery strokes of the pump by a cam-actuated lever 13 pivoted to a lever 14 which rests at its free end upon a governor lever 15. The lever 13 first opens a valve 11<a> in the by-pass and then the main valve 11. At starting, the ignition plug may spark continuously to warm up the combustion space.

Title: Improvements in aircraft landing gear
IPC: B64C25/00
Filed: 1944-10-23
Abstract: 594,541. Shock-absorbers. MILES AIRCRAFT, Ltd:, HEAL, L. C., and BURGER, F. E. Oct. 23, 1944, No. 20561. [Class 108 (iii)] [Also in Group XXXIII] An aircraft undercarriage is provided with a shock absorber which, under prolonged loading such as occurs during taxiing subsequent to the normal landing run or when the machine comes to rest, is effectively shortened in length to change the wing incidence to a value suitable for taking off. The strut comprises a high pressure cylinder 2 and piston tube 3, the latter housing an axially slidable low pressure piston tube 4 containing a floating piston 6, the space 15 above the tube 3 being filled with air and the space 11 between the tubes 2 and 3 by oil. The space 14 between the high and low pressure tubes 3 4 is occupied by oil, and that below the floating piston 6 by air. Upon landing the load is transmitted by the tube 4 and the oil in the space 14 to compress the air in the space 15, and also to transfer the oil in the space 11 from the upper to the lower side of an orifice ring 16, as described in Specification 582,608. Under prolonged loading, oil in the space 14 passes through an orifice 5 into a space 18 above the floating piston 6, thus compressing the air in the recuperator 7.' The length of the strut is thus reduced, the recuperator serving to restore the strut to its normal length when the aircraft becomes airborne. Reference has been directed by the. Comptroller to Specification 559,581 and U.S.A. Specification 2,008,094.

Filed: 1969-04-23
Abstract: 1,240,361. Automatic phase control. PYE Ltd. 23 April, 1969, No. 20745/69. Heading H3A. In a synchronizing system, a synchronizing signal from a remote point is compared with a local one, and is delayed in response to the phase difference detected to produce a residual phase error which is less than a given value, the residual phase error then being removed by a further phase control arrangement. In a first embodiment; Fig. 1, a signal from a remote station is applied at A, and is fed through two. delay networks 1 ... 9 and 10 ... 17 to a phase detector 20 where it is compared with a signal from a local generator 21 to produce an error signal which is fed to control unit 24. If the error is greater than a first reference level, switch S1 is actuated via motor M1 to insert delay until the error signal falls below the first reference level. When this occurs switch S2 is actuated via motor M2 until the error signal falls below a second reference level. The resulting residual phase error is then eliminated by a control loop in the slaving unit 25 which locks the two signals. This control loop may be of the type in which pulses are added to or subtracted from the input to a divider. In an alternative arrangement, Fig. 2 (not shown), binary delays are digitally controlled by a phase comparator of the type which counts the number of pulses from a clock source (40) which occur between local and remote synchronizing pulses (LOCAL, REM).

Abstract: 1461840 Polymerization in tetrahydronaphthalenes as solvent HOECHST AG 10 May 1974 [26 May 1973] 20858/74 Heading C3P In the polymerization of (1) a mono- and/or di-olefinically unsaturated monomer containing no free carboxyl or anhydride groups with (2) a mono- or di-carboxylic olefinically unsaturated monomer or derivative thereof, the polymerization is carried out at elevated temperature in the presence of a catalyst and tetrahydronaphthalene (or derivative thereof) as solvent with concomitant removal of any water present. The tetrahydronaphthalene derivative may be mono-substituted by C 1-4  alkyl, preferably methyl or ethyl. A constant reaction temperature in the range 150-205‹ C. is achieved by the formation of a binary or tertiary azeotropic mixture comprising water, organic solvent and/ or monomers. Solvent and unreacted monomers removed with the water through volatilization are recovered and recycled to the reaction mixture without purification. In batch operation 20-70% of the total amount of solvent used is heated to the desired polymerization temperature and then a solution, in the residual solvent, of the starting monomer mixture is gradually added to the heated solvent. The residual solvent may include solvent additional to the tetrahydronaphthalene. Monomer (1): styrene, α-methyl styrene, vinyl toluene, C 1-6  esters and hydroxyesters, amides and nitriles of acrylic and/or methacrylic acid, and diallyl phthalate. Monomer (2): maleic, acrylic, methacrylic, citraconic, itaconic and #-1,2- or # - 4,5 - tetrahydrophthalic acids, or an anhydride of any of these acids, if such exists. The additional solvent may be a diol having 2 to 4 carbon atoms or an ether thereof, methyl ethyl ketone, diacetalcohol, aceto-acetate and ethyl or butyl acetate. The reaction mixture, which is quenched to a temperature below 100‹ C. after the desired polymerization has been achieved, also includes peroxide catalysts (specified) and a chain regulator, e.g. dodecyl mercaptan. According to Example 1 the reaction mixture consisted of styrene, maleic anhydride, tetrahydronaphthalene, ethylene glycol monoethylether and monobutyl ether, di-t-butyl peroxide and dodecyl mercaptan.
