Title: Carburettor for internal combustion engines
IPC: F02M7/24
Filed: 1932-01-13
Abstract: 390,277. Spray carburetters. ERADE, C. J., 116, Rue de Serbie, Liege, Belgium. Jan. 13, 1932, No. 1091. Convention date, Jan. 13, 1931. Addition to 372,787. [Class 7 (iii).] The invention of the parent Specification is concerned with a carburetter in which the admission of the main air and mixture are controlled by a pair of butterfly valves, the auxiliary air being controlled by a cylindrical sleeve valve, all the valves being simultaneously controlled by a single member. According to the present invention either additional air is supplied under manual control or the cylindrical sleeve valve is replaced by a rotary disc valve or by a cam-actuated needle valve. As shown in Fig. 1, the auxiliary air enters through a duct 24. It is controlled by a cylindrical sleeve valve 29, which is operated through levers 30, 31, 32, simultaneously with the throttle valve 22 and with the main air valve (not shown). The auxiliary air is discharged over the fuel jet 28 and a valve 34 operated by hand admits additional air, which when the valve 34 is opened will reduce or prevent the delivery of fuel, air only being admitted through the carburetter, thus permitting a road vehicle engine to be used as a brake. The carburetter may have any number of jets any one of which may be subjected to the action of the restraining air. As shown in Fig. 6, a lever 30 moves a sleeve 43 containing a port 44 over a port 45 in a casing to control the admission of the auxiliary air. An additional supply of air is admitted through ports 59 controlled by a hand-operated valve 60. In other modified constructions the sleeve rotates inside the fixed casing and the valve 60 may be placed on the dashboard and be connected to the casing by a duct. The valves controlling the auxiliary and additional air may be mounted one above the other in the duct 24. Also, the duct 24 may be screwed into or out of the induction pipe to vary the area of the passage between the outlets of the duct and the fuel jet 28. In the modification shown in Fig. 2 the auxiliary air is controlled by a rotary disc valve 38 actuated by a lever 30, the valve having an aperture 39 which registers with an aperture 40 in the duct 24. A washer 41 having an aperture 42 may be inserted between the casing 24 and the disc 38. An additional air inlet 59 is controlled by a hand-operated valve 60. In the modified construction shown in Fig. 10, the lever 30 is pivoted at 50 and carries a boss 51 which acts on the end 52 of a needle valve 54 to control the auxiliary air admitted through a port 57 to a duct 58.

Title: Improvements in and relating to furnaces and boiler flues and fires
IPC: F23M20/00
Filed: 1919-01-20
Abstract: 141,793. Waring, W., and Waring, S., (Representative of Waring, E.). Jan. 20, 1919. Generating by waste gases.-The fire-bars of furnaces are replaced by a .bed of refractory material, on which is placed iron ores, pig iron, iron or steel scrap, or other irony substances, with or without the addition of limestone or other suitable flux. Solid, liquid, or gaseous fuel or waste gases may be supplied to the furnace, and where an intense heat is desired, the bed of refractory material may be provided with electrodes to convert the iron &c. into a molten condition. The Figure shows the invention applied to a water-tube boiler. The fuel and other materials are fed from the hopper 4 by the conveyer 5 on to the refractory bed 6 provided with water-cooled electrodes 7, 8. An arch 13 serves to form a combustion chamber and reflect heat on to the fuel on the conveyer as it is supplied. Air admission inlets 11 are provided in the wall 2. Producer gas, blast furnace gases or waste gases may be supplied to the furnace. When waste gases are employed, they are led over the molten material on the bed 6 through downwardlydirected passages in the wall 2, the conveyer 5 and arch 13 are dispensed with, and the irony substances are charged on to the bed 6 through the doors shown.
Patent GB-143272-A (GB)
Title: Improvements in and relating to multi-speed alternating current motors
IPC: H02K17/14
Filed: 1916-01-29
Abstract: 143,272. British Thomson - Houston Co., (General Electric Co.). Jan. 29, 1916. Alternating-current induction machines; motors, controlling; dynamos, regulating; windings.- Relates to induction motors of the kind described in Specifications 25858/03 and 26091/05, in which different speeds are obtained by changing the connexions of the primary winding to produce magnetic fields of different pole-numbers. According to the invention, the primary winding of the motor M, Figs. 1 and 14, comprises a number of circuits each of which contains conductors which carry current relatively in the same way in passing from one pole-number to the other, and the number of terminals of the winding is halved by permanently connecting one terminal of each circuit to a common neutral 16. The winding has thus as many free terminals as it has circuits, e.g. eight terminals in the two-phase arrangements shown in Figs. 1 and 14. The invention is shown in these Figures as applied to an electric powertransmission system in which the current from a generator G is led to the motor M. The method of grouping the conductors in the different circuits, is described at length in the Specification. The change of connexions from one pole-number to the other may be effected either by six or by eight single-pole double-throw switches 17 having a central off position. The armature of the two-phase generator G shown in Fig. 1 is provided with two independent windings 12, 13 and 14, 15 per phase; alternatively, the generator may have one winding per phase, the ends of the windings being connected to the mid-points of auto-transformers, and the free terminals of the auto-transformers being connected to the switch contacts. The armatum windings of the generator G may be connected in the form of a two-phase star, or, as shown in Fig. 14, in the form of a square 87, 88, 89, 90. For electric ship propulsion, the armature circuits of the generator may be changed from a square to a parallel connexion when the motor connexions are being changed from one pole-number to the other. The invention may be applied to motor secondary windings, which then comprise a number of circuits similar to those of the motor primary winding above described, and one of the terminals of each circuit is connected to a common neutral 16, Fig. 18; or the circuits may have two neutrals 16<1>, 16<11>, Fig. 19. The free terminals of the secondary winding may be connected together in pairs, as shown, the connexions being joined by slip-rings and brushes 97 to resistances 102, Fig. 18. For one pole-member of the primary winding, the secondary winding is in effect short-circuited on itself, while for the other pole-number, the resistances 102 are included in circuit. The currents induced in the secondary winding may be led to the primary winding of a second cascade-connected motor. Specifications 12361/15 and 15008/15, [Class 38 (iii), Electric motor control systems &c.], are also referred to.

Title: A monitoring circuit arrangement
IPC: H03G11/02
Filed: 1947-01-16
Abstract: 622,698. Monitoring circuits. BOSTON, D. W. Jan. 16, 1947, No. 1484. [Class 40 (iv)] In a sound-recording apparatus, particularly for sound films, a monitoring circuit is provided which indicates when over-recording is taking place by limiting the peaks of the sound waves in the same way as in the recording system. In a variable-width system in which the maximum width of the track is limited by the finite dimensions of the part of the film allotted for the sound track, the peaks of the sound waves are cut off during over-recording in the manner indicated in Fig. 1 and distortion occurs. The monitoring circuit is branched off from the main recording channel and may take the form of two diodes D1, D2 connected as shown in Fig. 2, in which the signal passes from the input terminals I to the output terminals O without distortion until the signal voltage exceeds that of the batteries B1, B2. When this occurs the diodes D1, D2 become conductive and the peaks of the waves are cut in a manner similar to that shown in Fig. 1, and audible distortion is produced in a monitoring loudspeaker. The control R may be set to a position in which the distortion in the monitoring circuit occurs simultaneously with, or slightly before, distortion occurring in the recording system. The monitoring circuit may be provided with an output transformer T1 and cathode-ray tube C1 as shown in Fig. 4, so that no indication appears until distortion commences. An alternative peak limiting and indicating circuit, Fig. 5 (not shown), takes the form of a triode valve followed by a glowdischarge lamp which strikes when distortion is taking place in the recording system, and serves both to limit the peaks in the monitoring circuit and act as an indicator at the same time.

IPC: F16P3/04
Filed: 1959-01-15
Abstract: 869,211. Machinery guards. HOUNSELL (ENGINEERS) Ltd., JOHN. Jan. 6, 1960 [Jan. 15, 1959], No. 1485/59. Class 80 (4). A guard for an hydraulic press or the like comprises at least one folding gate 7 formed of hinged sections guided by upper and lower horizontal rails 12 so that as the gate part thereof obtrudes into the path of the press platen 5 to prevent its descent. As shown there are two gates 7 each of which comprises an outer section fixed to a spindle 9 mounted in fixed bearings, an intermediate section centrally carrying upper and lower guide rollers 10, and an inner section carrying upper and lower guide rollers 11, the rollers 10, 11 engaging the rails 12. The two 'spindles 9 are coupled by chain and toothed gearing 15, 18 so that as a handle 13 on one gate is pulled both gates open simultaneously. The spindle 9 of the left-hand gate preferably carries an arm 19 actuating a switch 20 to prevent press operation unless the gates are fully closed. Each rail 12 is supported at its ends on the spindles 9 and has a central split 21 normally secured by screws 22, 24. Access to the platen 5 (e.g. for tool setting) may thus be obtained by removing screws 22, 24 and swinging the left and right rail sections, together with their associated gates, about the spindles 9. The platen 5 may then be inched down by manual operation of the switch 20.

Abstract: 174,919. Kuffel, D. C. Feb. 3, 1921, [Convention date]. Hooks, safety.-A safety hook for use in attaching buckets &c. to hoisting cables, comprises a primary hook member 11 and a secondary hook member 2. The secondary hook is pivoted about a pin 5 within a slot in the primary and can slide in the direction of a slot 11 under the action of a spring 22. Each hook member is doubleended and has oppositely-disposed points to those of the corresponding member, which are so shaped as to allow space for connecting links 20, 21 when the combined hook is closed. In the closed or lifting position, the link 20 bears against the face of a tapering point 25, so that the links cannot be removed without sliding the member 2 relative to the member 1 against the action of the spring 22. This can only be done when there is no load.

Title: Infrared analyzers
IPC: G01N21/37
Filed: 1957-01-16
Abstract: 818,102. Infra-red analysis. BECKMAN INSTRUMENTS Inc. Jan. 16, 1957 [Jan. 18, 1956], No. 1612/57. Class 40 (3). An infra-red analyser has two detectors of different gas charges in optical series relation, each containing pressure responsive members, the signals from which are united. Infra-red energy from a source 51 passes through a chamber 58 containing the sample gas into two detector chambers 65, 70. The first chamber 64 effects high absorption of energy in the wavelength of the sample and the second chamber absorbs energy primarily in other wavelengths. This may be achieved either by filling both detector chambers with the same gas at different pressures or with gases of different absorption, absorbing respectively in wavelengths of the sample gas and any interferent gas, and in the wavelengths of the interferent only. Energy from a source 50 passes through similar chambers 53, 64, 69 to act as a reference. Absorption of energy expands the gas in the chambers to move capacitor plates 66 and 71. The plates of the capacitors are reversed relative to each other to produce a signal 180 degrees out of phase and are connected in parallel to an amplifier 82, any unbalance producing an error signal which is amplified and used to control a servo-mechanism 83 which moves a shutter 84 to establish a null condition: the position of the shutter being a function of the unknown. The signals may otherwise be combined by a ratio circuit, the output being a function of the ratio therebetween. Trimmers 85, 86 are used to produce initial balances. The reference beam may be chopped by a member 52, the shutter 87 providing an initial balance between the reference and sample systems. Fig. 1 (not shown) illustrates the use of only one chopped beam.

Title: New derivatives of hexahydro-benzilic acid and pharmaceutical preparations containing them
Filed: 1957-01-16
Abstract: The invention comprises esters of hexahydrobenzilic acid and primary saturated aliphatic alcohols containing from three to six carbon atoms, and the manufacture thereof by converting hexahydrobenzilic acid or its functional derivative into an ester with a primary saturated aliphatic alcohol or a functional derivative thereof by a method known in the literature of the subject; also pharmaceutical compounds containing the above esters (see Group VI).  In an example, the alcohol and the acid are esterified in the presence of sulphuric acid.  Specific compounds described are the propanol-1, butanol-1, 2-methylpropanol-1, pentanol-1, 3 - methylbutanol - 1 hexanol - 1, and 2-ethylbutanol-1 esters of hexahydrobenzilic acid. Hexahydrobenzilic acid is prepared from cyclohexanol by converting it into cyclohexyl chloride, by esterification with hydrochloric acid, forming the Grignard compound and reacting this with phenylglyoxylic acid ethyl ester (previously prepared by esterification of the acid with ethyl alcohol) to form the ethyl ester of hexahydrobenzilic acid.  The free acid is obtained by saponification.ALSO:The invention includes pharmaceutical compositions comprising an ester of hexahydrobenzilic acid with a primary saturated aliphatic alcohol containing three to six carbon atoms (see also Group IV (b)) in admixture with a therapeutically acceptable vehicle.  Preparations include tablets, dragees, capsules, solutions, suspensions, emulsions for oral administration, injection or an aerosol, ointment, creams, and suppositories.  For esters liquid at room temperatures, absorbents such as oxidized starch, bolus alba, or colloidal silicic acid may be used in the preparation of tablets and cachets; suspensions, solutions and emulsions for oral administration are prepared in a fatty oil, such as arachis oil, or in water preferably stabilized by the addition of a gummy substance, for injection, in propylene glycol, glycerol, glyceryl diethyl ether (a mixture of alcohol, glycerol and water), oils, such as arachis oil, to which a wax may be added, water to which substances such as urethane, substituted amides, methyl glucamine, and polyvinyl pyrrolidone are added to enhance the solubility of the ester, or water containing a substance capable of reducing the surface tension of water to form a fine emulsion or suspension; ointments may also be prepared on a non-fatty basis in which the esters are dissolved, for example, in propylene glycol and polyethylene glycol waxes.  Examples are given of a tablet containing 2-methylpropyl hexahydrobenzilate adsorbed on lactose and oxidized starch, capsules containing n-pentyl hexahydrobenzilate in arachis oil, and ampoules containing a solution of 2-methylpropyl hexahydrobenzilate in 1 : 2-propylene glycol.
