IPC: H03K3/78
Filed: 1923-09-17
Abstract: 204,064. Huth Ges., Dr. E. F., and Kuhn, L. Sept. 16, 1922, [Convention date]. Keying and modulating systems and apparatus. -Relates to installations of the type in which a thermionic generator is fed with rectified current from an alternating source, modulating means D being inserted in the primary circuit of the supply transformer. According to the invention, the pulsating unidirectional current supplied by the rectifier to the thermionic tube has a frequency of at least 1000 and preferably between 5000 and 10,000 cycles per second so that it produces no audible or disturbing effect. A small condenser K arranged in parallel with the rectifier and thermionic generator prevents the short-circuiting of speech frequencies and at the same time permits of high-speed Morse signalling without " tailing." The magnetic modulator D comprising either a microphone M or signalling key T, may be made and sold as a separate unit from the rest of the set with the corresponding advantages of mass production.

Title: Inertial force compensation
Inventor: OLIVER WALTER LEONARD
IPC: G01L19/02
Filed: 1959-07-07
Abstract: 899,494. Dashpots. AVIATION, MINISTER OF. July 15, 1960 [July 7, 1959], No. 23280/59. Class 108(3). [Also in Groups XIX and XXXVIII] In an instrument in which the movement of a member in response to a variable is used as a measure of the variable, and in which errors are likely to be introduced by acceleration producing spurious movements of the member, a body is attached to the member and immersed in a liquid in a container attached to the instrument the density of the liquid and the size and density of the body being such that, under acceleration the liquid transmits to the body a force equal in magnitude but opposite in direction to the inertia force on the member on acceleration. In the pressure gauge shown, movements of pressure responsive diaphragm 8 produce changes in the inductance of coil 12 by varying the position of armature 10. Attached to the armature-diaphragm assembly is rod 42 supporting a body 40, of expanded polystyrene, inside a chamber 46 full of mercury. rod 42 being free to slide in seal 44. The size of the body is chosen such that its displacement weight in the mercury is equal to the weight of the diaphragm-armature assembly, in which case the inertial force on the assembly will be cancelled by the accelerating thrust of the liquid on the body 40. The inertial forces on a spring valve may be similarly nullified.

Patent GB-482579-A (GB)
Title: Process for treating sylvinite ores and product or products obtained thereby
IPC: C01D3/08
Filed: 1936-08-26
Abstract: Sylvinite ores, i.e. ores composed of naturally crystallized potassium chloride and sodium chloride together with clays and other gangue, are concentrated by forming a pulp by mixing the comminuted ore with a saturated solution of the ore, and subjecting the pulp to froth flotation to remove the potassium chloride as a froth concentrate.  Any potassium chloride remaining in the pulp may be dissolved by heating the pulp, the solution being then separated from the solids.  The solids are separated from the heated pulp by classification and thickening, a back-wash of sodium chloride solution being given to the solids in the classifier to produce a pure sodium chloride product.  The sludge from the thickener is discharged to waste after washing and filtering.  The excess potassium chloride is then removed from the thickener overflow by cooling in the presence of solid particles of potassium chloride, preferably those obtained in the froth concentrate; the chloride crystals are separated from the liquid by means of a classifier and a thickener, and the solids are washed with water or saturated potassium chloride solution.  The solid potassium chloride obtained is of a pinkish colour owing to inclusions of iron and manganese oxides contained in the sylvinite ore, and it may also contain hydrous silicates of magnesium and aluminium.  If desired, the potassium chloride may be dissolved to free the inclusions, which may be removed, e.g. by settling, and the chloride recrystallized on to other potassium chloride products.

Title: Improvements in or relating to fluid transmission systems
IPC: B60T11/32
Filed: 1946-07-29
Abstract: 638,352. Fluid-actuated valves. FIELDGATE, T. O., and LAWS, A. E. July 29,1946, Nos. 22509/46 and 21125/47. [Class 135] A fluid flow regulator, particularly for closing a passage in the event of excessive flow, comprises a pair of resistant passages respectively connecting a source of pressure fluid with a discharge orifice and with a space of variable volume formed wholly or in part by an elastic or spring-loaded bellows, and valve means sensitive to difference in pressure between the discharge orifice and the space of variable volume for controlling the discharge orifice. As shown in Fig. 1, a casing having inlet and outlet connections 14, 15 is provided with a partition 11 carrying a bellows 19 having a valve-member 21 coacting with a seat formed on the connection 15. A resistant passage 16, entering the inlet end of the casing between a pair of filters 17, 18 connects this end with the opposite end, whilst a further resistant passage, or number of passages 20, of greater total resistance than that of the passage 16 connects the interior of the bellows with the inlet. Upon an increase in flow above a predetermined amount the pressure drop through the passage 16 causes the bellows to expand and close the valve. The passages 20 restrict the rate of extension of the bellows so that the valve does not close until after a predetermined quantity of fluid has passed. According to Fig. 2, in which the inlet and outlet are at 24, 25, respectively, the space of variable volume is constituted by a space 37 in communication with a bellows (not shown), and a spring-loaded piston 27 has resistant passages 30a, 30b connected with the inlet by radial holes 31, 32. The valve proper is formed by an end 33 of the piston coacting with a resilient seat 34. The passage 30a causes retardation in the response of the piston to increased flow.

Title: Improvements in or relating to the manufacture of synthetic resins
IPC: C07F7/08
Filed: 1947-08-26
Abstract: Organo-silicon polymers useful for embedding electrical equipment and as coating compositions are produced by reacting a di-isocyanate derivative of a hydrocarbon with a polyhydric alcohol which contains at least two hydroxymethyl radicals bound to the same silicon atom or to different silicon atoms in the alcohol, and in which the remaining valencies of all silicon atoms in the molecule are satisfied either by the oxygen of siloxane bonds or by hydrocarbon radicals.  Suitable alcohols are of the types (CH3)2 Si(CH2OH)2, [(CH3)2(CH2OH)Si]2O, HOCH2 [Si(CH3)2O]xSi(CH3)2CH2OH, or [CH3(CH2OH) SiO]x, in which higher alkyl or phenyl radicals may be substituted for the methyl radicals.  The preparation of these alcohols is described in Specifications 630,952 and 631,049.  The reaction with the isocyanate may be carried out using reactants diluted with chlorobenzene or toluene. When aromatic di-isocyanates are used the products are soluble in glycol and polyglycols in which one of the hydroxyl hydrogens is substituted by a hydrocarbon radical, and in acetone, and methyl ethyl- or methyl butylketones, or alcohol.  In examples are reacted (1) symmetrical bis-hydroxymethyl-tetramethyl disiloxane and toluene 2,4-di-isocyanate in dichlorobenzene; (2) the alcohol of (1) and hexamethylene di-isocyanate; (3) toluene- and hexamethylenedi-isocyanates and the product of formula HOCH2(CH3)2SiO[Si(CH3)2O]3Si (CH3)2CH2OH obtained by reacting symmetrical bis-acetoxy methyl tetramethyl disiloxane and hexamethylcyclo trisiloxane in excess methanol and HCl; (4) toluene-3,5-di-isocyanate and the product of average formula <FORM:0631536/IV (a)/1> C6H5 CH3SiO)1,1 obtained by reacting a mixture of bis(acetoxymethyl) dimethyl diphenyl disiloxane and methyl stearyl dichlorosiloxane with ethanol; (5) toluene-3 : 5-di-isocyanate and a product of average formula HOCH2CH3C6H5 Si-[O Si(CH3)2]3-O Si CH3 C6 H5 CH2 OH obtained by the methanolysis of the disiloxane used in (4) in admixture with hexamethylcyclotrisiloxane.

Title: New or improved regulating device for a mixture-compressing injection-type internal combustion engine
IPC: F02D9/00
Filed: 1957-07-26
Abstract: 820,349. Regulating. DAIMLER-BENZ A. G. July 26. 1957 [July 31, 1956], No. 23771/57. Class 7(6) [Also in Group XXIX] A regulator for a mixture-compressing injection-type internal-combustion engine comprises a fuel injection adjuster directly operated by a control such as an accelerator pedal, a throttle regulating the combustion air, operative means connected with the throttle and under the combined influence of the control and an induction pressure-responsive means, and fuel injection resetting means under the influence of the induction pressure-responsive means and adapted for transmitting to the injection adjuster a corrective resetting which is performed against the direct operation of the control when the throttle is fully open at a time when the induction pressure is less than that corresponding to the maximum injection. In the arrangement shown the throttle valve 10 is operated by a servo-piston 12 through a control valve comprising a piston valve 16 mounted within a spring-loaded ported sleeve 15. The accelerator pedal 2 operates the control rod 4 of the fuel injection pump 5 through a spring 8 and rod 3, the latter of which carries a pin 27 engaging a slotted arm 25 by which a cross shaft 24 and cam 23 are rotated to operate the sleeve 15 through a pivoted arm 21. The piston valve 16 is controlled by induction pressure through a pipe 28, a bellows 30, and a floating lever 32 which has a movable fulcrum 33 carried by a bell crank lever 37 operated by a temperature compensater 33 in the induction pipe. In the event of abnormally low induction pressure, bellows 30 raises piston valve 16, whereby pressure fluid is applied to the top of piston 12, which descends and uncovers the end of a pipe 39 by which the pressure fluid is fed to the underside of a spring loaded piston 41, thereby raising a rod 43 which strikes an arm 45 carried by cross shaft 24. By this means arm 25 is rotated anti-clockwise to move rod 3 and pump control 4 to the left, against the resistance of spring 8, even with the accelerator pedal 2 fully depressed, thereby reducing the fuel supply, and raising sleeve 15 to cut off the fluid supply to piston 12. The pivoted end 20 of rod 21 is carried by an eccentric which can be adjusted by a hand lever under cold starting conditions.
