Title: Vacuum apparatus for raising liquids or priming pumps
IPC: F04D9/06
Filed: 1935-04-26
Abstract: 440,237. Centrifugal pumps. BERNARD, [nÚe BOURNONVILLE], R., 11<bis>, Avenue du MarÚchal Maunoury, Paris, [Representative of BERNARD, A. L. R.] April 26, 1935, Nos. 12589 and 12590. Convention dates, April 27, 1934 and June 29, 1934. [Class 110 (i)] [See also Group XXVIII] A method of raising liquids, more particularly for priming pumps, consists in connecting the induction pipe of an internal-combustion engine alternately to atmosphere and to the apparatus in which a vacuum is required. As shown the induction 'pipe 3 of an internalcombustion engine is connected to a chamber 7, which can communicate by a valve 14 with the atmosphere and by a valve 16 with the discharge pipe 4 of the pump to be primed. While the valve 14 is open the engine runs normally. If the valve 14 is closed the pipe 4 is exhausted past the valve 16 until the engine slows down. The valve 14 is then reopened until the engine recovers speed. This may be effected by a governor which operates a lever 29 to open the valve 14 when the speed falls and, when the speed rises, trips a pawl 34, which holds the lever 29. The valves 14, 16 may be mounted on a common, manually-operated rod, or the valves may be replaced by a threeway cock. Entrance of liquid into the engine may be prevented by a ball valve which floats in the liquid, or a valve 25 may be operated by a float 11. The pressure in the carburetter float chamber 37 is balanced by means of a passage 38. Apparatus for raising viscous or sandy liquids may be similarly constructed.

Abstract: 1,065,783. Automatic control; fluid pressure servomotor systems. HONEYWELL Inc. March 25, 1964 [March 29, 1963(3)], No.12693/64. Headings G3P and G3R. In a process control system, electrical digital signals corresponding to the deviation of a variable from a desired value are applied through a digital to fluid-pressure analogue converter which includes a pilot valve controlling a fluid-pressure actuator provided with follow-up. In Fig, 2, electrical digital signals representative of the deviation in the magnitude of a variable, e.g. temperature or liquid level, in a process 1, from a desired value set by means 6, are derived by a computer 36 and caused to operate coarse and fine servomotors 40, 53 in one sense or the other to a position corresponding to the deviation, Positional feedback is provided by potentiometers 42, 55. Servomotors 40, 53 operate cams 41, 54 to adjust the position of a flapper valve 62 relative to a nozzle 60 so that a pneumatic servosystem 66 adjusts a valve 3 and thereby corrects the deviation by altering a fluid supply to the process. Mechanical feedback from valve 3 is provided through a lever 68. In a modification, flapper valve 62 is in the form of an endless belt round the cams. In another modification there is only one servomotor which adjusts nozzle 60 through gearing, mechanical feedback being applied to the flapper valve. In this modification electrical feedback is derived from a potentiometer operated by the valve. Other arrangements involving cams, springs, force-balance units and limit stops are described for operating one or two flapper valves by a motor which may be reversible or not.

Title: Improvements relating to the supply of liquid fuel to burners
IPC: F23D11/44
Filed: 1926-05-19
Abstract: 265,053. Filma Oil Burners, Ltd., and Reid, E. A. May 19, 1926. Liquid-fuel supply.-In a hot-water heater for domestic use, a burner 6 such as described in Specification 180,202 is supplied with liquid fuel from a reservoir 3 which is maintained under pressure by a connection 8 to a pipe 7 leading from the air pump 5 to the burner. The fuel supply to the burner is diminished so as to maintain the temperature of the water practically constant by means of an air pressure release valve on the reservoir 3 operated by the expansion or contraction of the air in a copper chamber 11 which may be arranged in the furnace, or water space of the heater or in the return water pipe 12. The chamber 11 is connected by a fine bore pipe 13 to a pipe 17 which projects into a casing 15 secured to the reservoir 3 and carries at its lower end a diaphragm 16. A sleeve 18 formed with small holes 19 is attached to the diaphragm 16 and is slidable over an upwardly projecting pipe 21 which is formed with similar holes 22 and communicates with the reservoir 3. The movements of the diaphragm 16 caused by the expansion or contraction of the air in the chamber 11 moves the holes 19, 22 into or out of registration and controls the escape of air from the reservoir 3 into the casing 15. The pipe 17 screws through a member 24 which is rotatably mounted in the casing 15 to allow adjustment of the temperature maintained in the heater. The casing 15 communicates with the suction inlet of the air pump 5 through a hole 23 and pipe 32 of larger cross-section than the holes 19, 22. A spring controlled piston may be substituted for the diaphragm 16. The burner 6 may be arranged to project the flame downwardly as described in Specification 267,743.

Abstract: 1,172,723. Supply systems for electric discharge lamps. DURO-TEST CORP. 20 March. 1967 [23 March, 1966], No. 12900/67. Heading H2H. [Also in Division H1] A fluorescent lamp comprises a sealed envelope 24 with a pair of cathodes 18, 20 disposed at opposite ends of the envelope, each cathode of the pair including an angle of substantially less than 180 degrees, preferably 40-45 degrees, therebetween, wherein the main cathode 20 of each pair has the heater current and arc potential supplied to it via leads 12 and 16 whereas the auxiliary cathode 18 of each pair has the arc potential only supplied via common lead 16, the arrangement being such that the arc discharge is initiated and maintained between cathodes 20 until such time as they are exhausted of emissive material when the discharge will transfer to the cathodes 18 and because of the juxtaposition of cathodes 18 and 20 sufficient emissive material from cathodes 18 is then deposited on a respective adjacent cathode 20 to enable the cathodes 20 to function subsequently as starter electrodes; the lamp continuing to operate in this way until the emissive supply of cathodes 18 is exhausted. As shown, the other lead 14 of cathodes 18 is left unconnected, alternatively however it may be shorted with common lead 16, Figs. 5 and 6 (not shown). The lamp may be operated with either rapid start ballast, as shown, or pre-heat ballast, Fig. 4 (not shown), circuits. The cathodes of each pair may be exactly similar and located in a plane perpendicular to the envelope axis.

Title: Flow cell
IPC: G01N21/05
Filed: 1961-04-11
Abstract: 910,266. Colorimetric flow cells. TECHNICON INSTRUMENTS CORPORATION. April 11, 1961 [July 1, 1960], No. 12997/61. Class 97 (1). A flow cell for use in measuring the lighttransmitting characteristics of a liquid as it flows through the cell, has a pair of spaced walls and an inlet and an outlet so positioned that liquid will flow through the cell between these walls, the cell being characterized in that each of said walls has a light transmitting part and a light reflecting part so disposed that light entering the cell through a light transmitting part of one wall is reflected at the other wall beck on to the reflecting part of the first wall and then out of the cell through the light transmitting part of the other wall. The two reflecting parts are preferably parallel and inclined to the direction of the incident light. As shown, the continuous flow cell comprises a liquid chamber 12 to which liquid is supplied through inlets 32 communicating with pipes 26, Figs. 1 and 2, which are joined to a tube 68 having an inlet pipe 64 which can be connected to a conduit through which the liquid flows. In substantially vertical alignment with the two inlets 32 there are corresponding outlets 42, Fig. 3, communicating by pipes 34 with a single outlet tube 78, Fig. 2. In order to maintain equal hydrostatic pressure in the various parts of the flow cell, the tubes 68 and 78 and also a tube 25 which penetrates the top of the cell, are open to the atmosphere. Two end walls 14 and 16 of the liquid chamber 12, Fig. 3, are parallel and inclined to the vertical and provided with reflecting coatings 50 and 48 so that a light ray 52 will be reflected at 48 on to the coating 50 and thence out of the chamber in the direction 60. Alternatively, the end walls may be parallel and vertical, in which case each end wall has a thickened portion with a flat outer surface inclined to the vertical, each such portion being provided with a reflecting coating.

Title: Improvements in or relating to sliding contacts which remain closed in operation
IPC: H02K31/04
Filed: 1955-05-04
Abstract: 774,159. Current collectors employing conducting liquid. HENSCHEL & SOHN GES. May 4, 1955 [May 4, 1954], No. 13002/55, Class 35. The losses in a liquid contact collector for single pole generators, are reduced by improving the electrical conductivity by perfect cleanliness of both surface metals and liquid ; by reducing the friction loss by using a small area of contact, so that the current density is more than 2 amps/mm.<SP>2</SP>, and cooling the liquid by circulating it; and by reducing the kinetic loss by employing a very short liquid path. The solid contacts are preferably non-tarnishable and not liable to form amalgams, e.g. molybdenum, tungsten, chromium, platinum or carbon, or the surfaces may be coated with such materials. Iron may be used provided it is kept under mercury. Instead of mercury, alloys such as Wood's metal or sodium-potassium alloys may be used. In the form shown in Fig. 2b, in which member K1 rotates within member K2, mercury is fed down a tube into the contact gap SP from whence it is driven by centrifugal force to a cooler (not shown). Air is kept out by a mercury seal HgSp. In a modification, Fig. 3, the rotating member K2 has an annular groove accommodating the stationary contact, the mercury lying in the bottom SP1 of the groove at rest or low speeds, and occupying the outer cylindrical surface of the groove at speed. In either case, and at intermediate speeds there is a small area of contact at the corner HK of the groove with the edge na of the stationary contact, these contact points being of special material, e.g. molybdenum. The mercury is circulated, after being flung from the top lip Ka of the rotating contact, through a duct K1 having a cooling arrangement, e.g. coils Ku. The liquid contact may act at one or more single points on the periphery of the moving contact, and forms of the invention are described in which the mercury is directed as a jet on to the moving surface and almost instantly caught by a scoop, or the mercury makes contact at the end of a vertical rotating member having a cup containing the contact mercury which moves radially under centrifugal force. In order to maintain the spacing of the rotating and stationary contacts as accurately as possible, the stationary parts may be supported on the rotor shaft, through suitable bearings instead of from the stator of the machine: In one form the mercury jet and scoop are mounted in a sleeve surrounding the shaft, lubrication being provided by compressed air supplied by further jets on either side of the mercury jet. For very high speeds, the losses may be reduced (see Fig. 17) by the use of an intermediate member R rotating at an intermediate speed, e.g. half, mercury being supplied to the two gaps S1, S2. If desired, the device may operate in a vacuum or inert gas.
