Title: Improvements in or relating to thermionic amplifying systems
IPC: H03C1/06
Filed: 1936-08-14
Abstract: 479,882. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and STRONG, C. E. Aug. 14, 1936, No. 22462. [Class 40 (v)] In an amplifier comprising a push-pull output stage and provided with a negative feed-back path for feeding back waves including the range of transmitted frequencies, the voltage to be fed back is derived from tappings adjustable to positions unbalanced about the earth point on impedances connected between the plates of the output valves. By this means, the proportion of the output voltage which is fed back can be readily controlled, and a desired amount of additional second harmonic component can be fed back at the same time. The input stage 2 of the amplifier may be a single valve or the early stages may be Class A pushpull amplifier stages, and the feed-back path may be connected to the resistance bridge 6, the feed-back voltage being obtained from a potentiometer 4, connected across the primary winding of the output transformer B, by adjustable tappings which are on either side of the earthed centre point of the potentiometer. By maintaining the distance between the tappings unchanged but adjusting them along the potentiometer it is possible to feed back second harmonic voltages in adjustable degree. The tappings are connected to a low-power transformer D, having a wide frequency response characteristic, the secondary winding of which is connected to the bridge 6.

Patent GB-405699-A (GB)
Title: Improvements in or relating to the manufacture of esters of methacrylic acid
IPC: C07C69/54
Filed: 1932-08-12
Abstract: Methacrylic acid esters of monohydric alcohols are manufactured by treating acetone cyanhydrin with concentrated or fuming sulphuric acid at a raised temperature ranging from below 80 DEG  C. to somewhat above 100 DEG  C., advantageously at 100--110 DEG  C., and then heating the reaction mixture with a monohydric alcohol, e.g. ethyl, methyl, propyl, butyl, amyl or cetyl alcohol, cyclohexanol, ethylene glycol monoethyl ether, ethylene glycol monoacetate or ethylene chlorhydrin.  Advantageously the mixture of acetone cyanhydrin and sulphuric acid is maintained at a temperature above 80 DEG  C., preferably about 140 DEG  C., for at least an hour before adding the alcohol.  The acetone cyanhydrin used may be the crude product obtained by reacting hydrocyanic acid and acetone in the presence of a catalyst, the best results being obtained when the cyanhydrin has been cooled to -15 DEG  C. before neutralization, using potassium carbonate or a strong organic base as catalyst.  The amount of sulphuric acid, which is preferably of 94--100 per cent strength, should be at least one molecular proportion and preferably rather more, e.g. 1\ba1/4\be--1\ba1/2\be molecular proportions, to one molecular proportion of cyanhydrin.  The reaction with the monohydric alcohol may be performed in a closed vessel, in a vessel with a reflux condenser or under such conditions that the ester produced is distilled off, and it is preferably carried out in the presence of anti-polymerization materials, e.g. sulphur, diphenylamine, copper, hydroquinone or cresol, which are desirably added at an early stage.  The esters may be recovered by diluting the reaction mixture with water or by distillation, preferably vacuum or steam distillation, and may be purified by washing with water or dilute alkali followed by drying, e.g. over calcium chloride, and redistillation in the presence of a polymerisation inhibitor. Examples describe the preparation of methyl, ethyl and n-butyl methacrylates, in some cases together with a certain amount of the corresponding ester of a -hydroxyisobutyric acid.

Title: Improvements in fuel injection pumps for internal combustion engines
IPC: F02M41/08
Filed: 1945-09-04
Abstract: 598,454. Fuel-injection pumps. CALLISTO. Sept. 4, 1945, No. 22757. Convention date, Aug. 18, 1944. [Class 102 (i)] [Also in Group XXIX] A reciprocating liquid-fuel injection pump for an internal-combustion engine from which the output is controlled by varying the suction valve opening comprises a plurality of plungers 4 operating in cylinders 3 disposed in barrel formation about a central driving shaft 2 and reciprocated by means of a cam disc 4a. Interposed between a pump body I and a push block casing 17 is a diaphragm 5 to which is riveted by means of a retaining plate 14 a push block 15 operating a spring loaded suction valve 9 which is actuated and controlled by means of a rotating cam disc 28 secured to a cylindrical body 29 that surrounds a part of the drive shaft 2. The shaft is fitted with radial vanes 34 which cooperate with like vanes 33 mounted in the cylindrical body 29 to provide liquid sealed compartments adapted to effect a hydraulic transmission from the shaft 2 to the valve control cam 28 via the cylindrical body 29. Oil is either supplied or withdrawn from the sealed compartments through an axial passage 37 which is in communication at 65 with a port 64 of a sliding control valve 52 operated by a manometric capsule 47 subjected to the induction pressure of the engine. In operation, expansion of the capsule to the right moves the lever 50 and the slide valve 52 to the left and puts the port 64 in communication with a discharge port 62 thereby effecting a withdrawal of oil from the sealed compartments which causes the cylindrical body 29 to be displaced thus modifying the setting of the cam disc 28 in relation to the drive shaft 2 with a resultant variation in the amount of fuel injected. Relative movement of the cam disc 28 causes a corresponding rotation of a helicoidal track 41 secured in the cylindrical block 29 to move runners 43 guided in a groove 45 in a slide block 42 which actuates a spring urged lever 48 resting on the thrust block 46 to cause the capsule 47 to be displaced to the left to return the control valve to its neutral position. Specification 468,367 is referred to.
