Title: Improvements in carburetors
IPC: F02M7/00
Filed: 1932-11-10
Abstract: 410,483. Spray carburetters. LINGA, T., Kokomo, Indiana, U.S.A. Nov. 10, 1932, No. 31823. [Class 7 (iii).] In a carburetter in which the float chamber is under a suction sufficient to lift the fuel from a low-lying tank, means in the float chamber control the position of an auxiliary air valve. Liquid fuel is drawn by suction from a float chamber 22, Fig. 1, through passages 33, 30, 39 to a closed tube 41, which extends above the level of the fuel in the float chamber, and passes through passages 40, 44 to a fuel nozzle 19 located in a Venturi passage 14, 18. The depression existing in the chamber 40 is transmitted through an orifice 73 to a chamber 72, where it is reduced by a small air-bleed port 74 opening into the mixing chamber 13. An orifice 71 transmits this reduced depression to the top of the float chamber, where it elevates fuel from a supply tank located at a lower level than the carburetter. A flexible diaphragm 25 is clamped between the body and the cover of the float chamber, and carries a nut 53 upon which bears the head 54 of a spring-pressed lever 52, mounted upon a shaft 56 in an eccentric sleeve 57. As the suction in the float chamber increases, the diaphragm flexes against the action of a spring 32, and the lever 52 through links 59, 61, 62 opens an auxiliary air valve 16 to maintain a substantially constant depression in the float chamber. During starting, the valve 16 is held closed by operating a cable attached to an arm mounted on the sleeve 57. A plunger 45 is fixed to the diaphragm 25 and houses an adjustable rod 46 having a hollow part 47 to which is attached a flexible wire 49 carrying a tapered valve 51. The valve 51 is suspended within a calibrated port 37 through which the fuel supplied to the nozzle passes, and as the diaphragm flexes the port 37 is opened. The fuel supply for idling is adjusted by altering the position of the valve 51 by means of the adjustable rod 46. At high speeds the richness of the mixture is controlled by a manually adjustable valve 43. When accelerating, (1) the diaphragm will move downwardly and, as the air beneath it cannot escape quickly through the small orifice 71, the pressure in the float chamber increases and fuel will be forced out of the float chamber through passages 77, 76, 75, Fig. 3, into the chamber 72, from which it passes through the opening 73 into the main fuel passage 40, 44 ; and (2), due to the retardation of the downward movement of the diaphragm 25, the opening of the auxiliary air valve 16 is delayed. During the last eighth of the opening movement of the throttle valve 15, a slot 85 in its shaft registers with a passage 82 leading to the chamber 72 through passages 81, 79, 78, and thus the difference in depression between the port 37 and the top of the float chamber is increased, and extra fuel is supplied through the port 37. The space above the diaphragm in the float chamber is connected with the conduit 17.

Title: Receiver for a data transmission system
IPC: H04L27/26
Filed: 1973-07-04
Abstract: 1383168 Receiving apparatus for a plurality of asynchronous data inputs INTERNATIONAL BUSINESS MACHINES CORP 4 July 1973 [7 Aug 1972] 31855/73 Heading G4H Receiving apparatus for coded dialling information where asynchronous input signals consisting of, e.g. 2 superimposed frequency signals, a first from a first group of frequencies and a second from a second group, are fed along a line, each pair of frequency signals being indicative of 1 digit, the pairs being fed sequentially possibly for varying time intervals, is adapted to process information simultaneously from, e.g. 60 input lines without loss of information and comprises an A/D converter for producing sequential samples of the input information on corresponding output lines, a storage register coupled to each output line and a multiplexer means for sequentially and periodically reading out the stored samples, the rate at which the stored samples are read out of a particular one of the storage means being much greater than the rate at which they were fed into that storage means, and the set of samples read out from each storage means containing a part of the information read-out therefrom in the preceding multiplex cycle. As shown, the frequency information is fed in by lines 38a-38n to a single A/D converter having a switched input and output and fed as digital samples to corresponding shift registers 42a-42n. Having regard to the maximum likely input frequency and a minimum code recognition time (e.g. 40 msecs), a sample is introduced into a particular register every 60 Ásecs and with 60 input lines, the switches are changed every 1 Ásec. Each shift register 42 consists of two parts each of, e.g. 680 stages a first for holding the present 680 samples and a second for the previous 680 samples. Since the minimum code recognition time is taken as 40 msecs, at the above sampling rate this number represents a time of 40 msecs. The multiplexer 46 causes read-out of each register 42 every 40 msecs. and the individual samples are clocked out at a frequency of 2 MHz. Both parts of the registers are read out by the multiplexer 46 and the samples of the first part are also overwritten in the second part during the read-out process. The multiplexed digital information is then taken via D/A converter 56 to a decoder 62 consisting of sets of filters, threshold circuits and gates and D.C. outputs on certain output leads are produced according to which frequencies are present. These outputs are then taken to a demultiplexer and logic circuit 64 where the individual inputs are retrieved and the coded signals derived with regard to the mill-spaces between each digit. The overlapping of the information by the shift registers ensure that there is no loss of information in the multiplexing process.

Abstract: 499,857. Valves; thermostats. BRITISH THERMOSTAT CO., Ltd., and HURST, W. F. F. MARTIN. Nov. 2, 1937, No. 31905 /36. [Class 135] [Also in Group XIII] Thermostatic valve apparatus for regulating the cooling of internal-combustion engines in a, manner independent of the atmospheric pressure, comprises a bellows 18 containing a volatile liquid coupled by rods 22 with a second sealed bellows 19 containing air. When the engine is cold, the parts are situated as shown. When it begins to warm up, cooling liquid rises through the inlet 2 past the bellows 19, through holes in a partition 17, to which both bellows are secured, past the bellows 18, through holes 11a in a valve member 11 and away by a pipe 4 back to the engine. As the temperature rises, the pressure in the bellows 18 rises more rapidly than that in bellows 19 and a valve 7, carried by a stem 8 mounted on the top of bellows 18, is raised to open the exit 3 to the radiator. At the same time a seat 10a on the valve 11 approaches a seat 10 on the casing and gradually cuts off the liquid from the pipe 4. Expansion of the bellows 19 is limited by stops 23 on a frame 23a. The upper bellows are charged with liquid through a bore in the stem 8 which is afterwards sealed at the upper end. The lower bellows are charged with air through a pipe 22a which is afterwards sealed.

Title: Improvements in or relating to a method and machine for the manufacture of cut-edge fabric
IPC: D06H7/22
Filed: 1945-11-26
Abstract: 588,810. Cutting-machines for fabrics. WAGNER, W. B. Nov. 26,1945, No. 31916. [Class 31 (i)] Fabrics formed from threads or yarns of a thermoplastic synthetic material such as cellulose acetate are cut to form ribbons by means of an unheated cutting device such as a disc cutter 13, which presses a web 11 of the fabric into contact with a heated roller 2. The web 11 is fed from a roll 1 by feed rollers 3, 4, 5, and passes over guide bars 6, 7 which normally tend to keep the web out of contact with the roller 2. The roller 2 is heated by an electrical coil to a temperature not less than 350‹C, and the pressure of the knife or knives on the roller, and the speed of the web are adjusted so that the cutting and fusing of the severed threads together are effected without substantial decomposition of the fabric. A number of cutters 13 are arranged side by side, and are mounted in forked members 14 carried by bars 15 supported from a fitted girder 9 and a pivotally supported girder 12, and alternate cutters are similarly supported from two sets of girders 25, 26. Adjustable springs are arranged between the girders 12 and the ends 19 of the bars 15. To control the heating effect the cutters 13 may coact with grooved parts 28 of the roller 2 as shown in Fig. 4, which enable fusion to take place over a wider area than when the roller 2 is not grooved. Or the roller 2 may be fitted with a number of rings 8, Figs. 6 and 8; in heat connection with the roller, and these rings can be grooved, or provided with chamfered edges 29, 31, Fig. 6, or formed with slots 32, Fig. 8, which may be also formed with grooves 33. Edges of fusion occur where the fabric touches the edges 32, 34 of the slots, and this gives the effect of a woven edge. The apparatus may be used to form a hollow ribbon by treating superposed webs. The roller 2 and its co-operating knives may be adjustable transversely across the machine frame to compensate for wavering of the fabric. Specifications 477,662 and 544,379 are referred to.

Title: Process and apparatus for influencing the growth of organisms
IPC: C12M1/16
Filed: 1958-10-07
Abstract: In a process for promoting and/or inhibiting the growth of micro-organisms, there are disposed on the upper surface of a porous membrane, for example, a dried gel of a mixture of cellulose esters, below which are disposed one above the other two or more separate, insert, solid carriers e.g. of filter paper, each of which is impregnated with a soluble nutrient and/or growth inhibiting medium. The carriers are first saturated or painted with a solution of the medium, then dried and sterilized.  When required for use, sufficient water or a buffer solution is added to regenerate the solution which passes from the carriers through the membrane to the micro-organisms. Conditions are adjusted so that the materials held by each carrier are kept substantially separate from each other and reach the micro-organisms successively.  Reference is made to the application of the process in the testing of sewage and bacteria, yeasts and fungi are referred to generally.  An apparatus for the process is described wherein the carriers &c. are contained in a glass vessel. A method of sterilization of the dried carriers is described wherein these are sealed in a container composed at least partly of a synthetic foil e.g. polyethylene, and which is exposed to a gas composed partly of a sterilizing gas e.g. ethylene oxide which permeates the foil.  The container is then placed in a gas not containing the sterilizing gas whereupon that inside the container diffuses out through the foil.

Abstract: 1472569 Sprinkler for fire fighting GRINNELL FIRE PROTECTION SYSTEMS CO INC 19 July 1974 [2 Aug 1973] 32079/74 Heading A5A A sprinkler for fire fighting comprises a body member with a lower body portion 10 containing a fluid inlet 11 and couplable to a source of pressurized fluid e.g. water, a cylindrical control chamber 30 formed in the body member in axial alignment with the inlet 11, a piston slidably and sealingly disposed in 30 and comprising a piston portion 36 and a valve portion 44 which sealingly closes the downstream end 14 of inlet 11, a cylindrical bore 32 in the body member in axial alignment with 30 and in communication therewith, a tubular guide member 50 mounted axially in the piston and extending partially into and fitting loosely in bore 32, a passage 56 in the piston to allow fluid to pass from 11 into 30 wherein the effective area of the piston portion 36 exposed to the fluid pressure is greater than that of the valve portion 44 so that the piston urges the valve in the closed position aided by biassing coil spring 52, a ball check valve 62 in bore 32 to prevent fluid flow from 30 to 11, and an outlet port 70 for releasing fluid from 30 when a pilot valve 64 opens in response to a predetermined temperature. The pilot valve 64 operates by means of a bi-metallic "snap-action" disc which on reaching the predetermined temperature opens pilot valve 64 so releasing fluid pressure from 30 via 70. The fluid pressure on the piston portion 36 is now less than that on the valve portion 44 so the fluid pressure lifts the piston and fluid exits from 11, contacts deflector 48 and forms a sprinkler pattern. On cooling below the predetermined temperature, pilot valve 64 snaps shut and the reverse process occurs.

Abstract: 686,303. Flexible abrasives. SIMPSON, H. A. Jan. 10, 1950 [Dec. 14, 1948], No. 32294/48. Class 60. A flexible abrasive disc is made by cutting from sheet material e.g. vulcanized fibre, cardboard, regenerated cellulose, a base disc to its desired final shape and size including a central hole, applying abrasive material to the surface of the disc after applying an initial coat of adhesive material e.g. thermo-setting synthetic resin, natural resin, or glues, to said surface, applying a second adhesive coat, mounting the disc on a support provided with means for keeping the disc flat, and subjecting it to a heat treatment to set the adhesive. In a specific process, a disc 10, to which adhesive and abrasive coats have been applied, is mounted abra.- sive surface uppermost on a jig comprising a plate 12 which is secured to a conveyer or part of an oven tray 14 and which is undercut with respect to the disc i.e. the diameter 16 is less than the diameter of the disc and the diameter of an aperture 18 is greater than that of a hole 20 in the disc, to ensure that excess unset adhesive will not bond the disc to the plate. A plate 24 is placed over a bolt 22 on the tray 14 and secured by a nut 30 so that protuberances 28 engage and secure the disc 10 flat on the plate 12. The tray is placed in or conveyed into an oven wherein the jig is maintained level and after the heat treatment the disc is allowed to cool in the oven or normal atmosphere: the disc may be treated, as in a steam chest, to restore its moisture content and may be given a coat of a water repellent substance. A clip, conical plug, or U-shaped or other form of clamping member (not illustrated) may be used instead of the washer 24.
