Title: Improvements in carburetters
IPC: F02M37/02
Filed: 1926-03-30
Abstract: 265,905. Seignol, E. Feb. 9, 1926, [Con. vention date]. Spray carburettors.-In carburettors, e.g. of the type described in Specifications 251,584 and 251.585, wherein rich mixture is produced in a primary carburettor situated for example near the fuel tank and is drawn through a tube of relatively large diameter into a secondary carburettor comprising a venturi through which the main air supply passes, the inlet to the venturi is provided with a valve the opening of which, when the throttle is opened, is retarded so as to prevent undue weakening of the mixture, faulty acceleration and stopping of the engine. Rich mixture, is delivered through a tube d to the engine side of the throat c of a venturi a located in the main passage which has a throttle-valve b, and a suction-actuated air inlet valve i in the form of a flap. Mixture for slow running is supplied through a tube h. The air flap i, pivoted at j, is connected through linkage k, l to the rod m, Fig. 2, of a piston n in a cylinder o which communicates with the atmosphere at rand with the engine side of the. throttle valve through a duct p controlled by a valve q. With the throttle closed, suction acts upon the piston and closes the air flap. Upon opening the throttle, the suction acts upon both the flap and the piston, but the flap being of larger area is opened, but only gradually, owing to the resistance offered to the downward movement of the piston n. In modifications, the application of the device to the two forms of carburettor disclosed in Specification 265.904 is described. Reference has been directed by the Comptroller to Specifications 21934/07 and 193.706.

[Also in Groups XXXV and XL (c)] A cross-field modulator consists of a saturable inductor comprising a powdered magnetic core 20, 21 in the form of a hollow toroid, one winding 10 being wound circumferentially within the core and the other winding 12 around the core in the form of a toroid; thus there is no inductive coupling between the two windings. A.C. is applied to the winding 10 to periodically saturate the whole core 20, 21 thereby varying the permeability of the core and modulating a D.C. signal applied to the other winding 12 to produce an A.C. output from this winding. A further winding may be associated with the winding 12 to form a transformer, the output then being taken from this further winding. To obtain an A.C. output of fundamental frequency instead of double this frequency the winding 10 may be fed with A.C. over a halfwave rectifier; alternatively a D.C. bias may be used. Two such modulators in series may form a voltage multiplier.

Filed: 1951-04-24
Abstract: 693,660. Hydraulic dampers. DAIMLERBENZ AKT.-GES. April 24, 1951 [April 25, 1950], No. 9537/51. Class 108 (iii). A piston - and -cylinderhydraulic damper has a by pass operative in the middle range of movement of the piston 9, formed by a longitudinal by-pass slot 13 in an auxiliary cylinder 11 which is slidable within the main cylinder 3, a driving connection being provided between the piston 9 and the auxiliary cylinder 11. In the construction shown in Fig. 1, the driving connection comprises springs 14, 14a. In operation, on relatively small deflections of the piston rod 6 in either direction, liquid is displaced from one side to the other of the piston 9 via the slot 13. On larger deflections, the piston 9 cuts off the end of the slot 13, and a positive thrust is applied to the cylinder 11. Greater damping then occurs by virtue of the damping produced on compressions and rebound respectively by the flow through orifices 23, 23<1> in the flap valves 18, 18<1>. In a modification, Fig. 2 (not shown), the valve 23<1> may be carried by the piston 9. The piston head 15 on the cylinder 11 is then dispensed with and the cylinder 11 is open-ended. The slot 13 may or may not be assymmetrically disposed in relation to the normal inoperative position of the piston (e.g. by suitable dimensioning of the springs 14, 14a). There may be a plurality of slots 13. Damping is arranged to be greater on the rebound stroke.

Abstract: 860,485. Fluid-pressure servomotor-control systems. FOXBORO-YOXALL Ltd. April 20, 1959 [March 26, 1958], No. 9760/58. Class 135. An automatic force balance device for producing an output signal bearing a predetermined relationship to an input signal, comprises a lever mounted to rock about a fulcrum, means for applying two forces arranged to rock the lever in one direction about the fulcrum, means for applying two further forces arranged to rock the lever in the opposite direction about the fulcrum which is adjustable relative to the points of application of the forces, three of the force applying means being interconnected by means including at least one time delay device so as to transmit the input or output signal and the fourth force applying means serving to transmit the output or input signal respectively, the output signal being determined by means responsive to the position of the lever. In the first example, Fig. 1, the lever 1 is acted on by four bellows A, B, C, P at points 3 and 4 between which the fulcrum 2 is adjustable. The input signal is fed to bellows A which is connected via at least one variable resistor R to bellows B and C. The lever extension 12 cooperates with a nozzle 13, the back pressure of which constitutes the output signal and is fed to the bellows P via the relay 10. The position of the fulcrum 2 determines the gain and the phase angle of the output signal for input signals of a frequency within a limited range. In another embodiment, Fig. 6, the position of the fulcrum 2 is determined by a signal representing the error or a function of the error in the associated control loop and applied to the bellows 18. In order that this latter signal may be independent of the direction of the error, the use of the device illustrated in Fig. 27 is suggested. This device comprises a desired value bellows 30 and a measured value bellows 31 which position a lever 32 connected through the linkage 34, 38, 39, 40, 42 to the pneumatic relay 45. In another example, Fig. 18, an additional RC network is inserted between the relay 10 and the bellows P whereby the gain is multiplied by a predetermined factor. Specifications 670,427, 740,179, 740,238, 764,660 and 827,207 are referred to.

Title: Improvements in the manufacture of soap products
IPC: C11D9/26
Filed: 1941-08-01
Abstract: 553,735. Granulated soap. LEVER BROS. & UNILEVER, Ltd. Aug. 1, 1941, No. 9817. Convention date, Aug. 3, 1940. [Class 91] Soap granules are coated with a substance to maintain them in a form resistant to disintegration and to reduce the amount of soap dust formed therefrom. The dust may be formed through various causes and the function of the coating agents may vary accordingly. In general, the coating agents comprise two groups of materials. The first group consists of substances which are hygroscopic and maintain the moisture content of the granules, also have the property of binding the dust particles thereto, and reduce the formation of static charges on the particles. The second group consists of substances which primarily strengthen the soap granules and also bond the dust particles; they are preferably insoluble in the soap and may be water soluble, water dispersible, or water insoluble. In the last case, the granules are only discontinuously coated. Substances specified in the first group comprise polyhydric alcohols, such as glycerol, ethylene glycol, diethylene glycol, sorbitol and mannitol ; inorganic and organic phosphates, such as dipotassium phosphate, alkyl phosphates of formula MRHPO 4  such as potassium inethyl or ethyl phosphate, sodium potassium ethyl phosphate, triethanolamine ethyl phosphate, and phosphates of formula (RO) 3 PO such as tricresyl phosphate, tributyl phosphate, dibutyl phenyl phosphate, trixylenyl phosphate, diphenyl cresyl phosphate and phosphate esters of glycol ethers ; high boiling white oils or other oils, water soluble sulphonated oils or a waxy material such as carbowax. Mixtures of these materials specified comprise glycerol and dipotassium phosphate or sodium potassium ethyl phosphate or potash coconut oil soap, water soluble sulphonated oils and lithium chloride. Substances specified in the second group comprise methyl cellulose, polyvinyl alcohol, corn or potato starch, soluble starches and dextrins. The soap granules may be coated by allowing them to fall once or repeatedly through a mist of the atomized coating material or by tumbling them in a rotary drum to which a spray of the atomized coating material is admitted.
