Filed: 1922-10-16
Abstract: 208,845. Corrie, W. Oct. 16, 1922. Single-trigger mechanisms.-A sliding searlifter g on the trigger blade c is prevented from moving forwards into position for engaging the second sear, until after the involuntary pull, by a sliding inertia block a which is moved forwards by the recoil. Fig. 1 shows the mechanism from the right-hand side set ready for firing the first barrel, and Fig. 4 shows the left-hand side with the trigger blade moved to the position for nring the first barrel. The searlifting slide g mounted in the trigger blade c is pressed forwards by a spring m and has lateral projections l, p, one on each side, for engaging the sears, and a projection f, Fig. 4, at the front on the left-hand side adapted to pass under a projection into a recess h in the trigger box e when the slide moves forward into position for firing the second barrel. This forward movement is checked by a slide a, Fig. 4, which is moved forward by the recoil to engage under the projection f which is thereby held up against the shoulder or the trigger box until after the involuntary pull and release. The slide a is then returned by its spring d and the sear-lifting slide is free to move forwards.

Title: Process for the smelting of iron ores having a high sulphur content
IPC: C21B5/00
Filed: 1931-10-10
Abstract: In a process for smelting iron ores having a high sulphur content, supplemental air to that required for ordinary sulphidic ores is passed into the charge comprising ore, flux and coke, the volume of such air being 30 per cent or more of that required for ordinary oxidic ores and being introduced into the blast furnace when, with such ores, the reduction of the ore is complete.  The extra air may be forced into the furnace through the ordinary twyers or through twyers disposed in one or more planes above the ordinary twyers.  The sulphur dioxide produced in the lower part of the furnace is reduced by contact with solid carbon and carbon monoxide to sulphur, which passes off with the waste gases from which it is separated by means of gas washers, electric filters, or Beth filters.ALSO:In a process for smelting iron ores having a high sulphur content, supplemental air to that required for the reduction of ordinary sulphidic ore is passed into the charge comprising ore, flux and coke, the volume of such air being 30 per cent or more of that required for the treatment of ordinary oxidic ores and being introduced at the point in the blast furnace where with such ores the reduction of the ore is complete.

Title: Gas meter
IPC: G01F3/22
Filed: 1966-06-24
Abstract: 1,109,325. Gas meters. AMERCON CORPORATION. June 24, 1966 [Aug. 2, 1965], No.28412/66. Heading G1R. A gas meter comprises two transfer valves 25, 26 at the top each associated with a pair of measuring chambers divided by a diaphragm and each provided with a flag rod 20, 22 connected to respective flag arms 52, 53, a register driveshaft having a crank arm with a crank-pin 66, a pair of links 61, 62 extending substantially at right angles to each other from the crank-pin to one and the other flag arm 52, 53, and a link 56, 57 extending from each flag arm to the transfer valve 25, 26 respectively associated with the other flag arm. The valves 25, 26 are guided by pins (not shown) engaging in slots 29, 30 in arms integral with the valve members and the flag rods 20, 22 are disposed at diagonally opposite sections of the meter casing which is rectangular in plan. The flag arms 52, 53 are in the form of bell cranklevers and are connected to the register driveshaft crank-pin 66 by the links 61, 62. The crankpin is disposed in a circular bearing and is itself of flattened section so that it acts as a tight bearing along axis 68 but has lost motion along axis 69. The driving force from the link 61 along axis 68 will provide close correspondence between the motion of the flag arm 52 and the valve 26 whilst the flattened crank-pin will allow lost motion between the flag arm 53 and valve 25 with the parts in the positions shown in Fig. 9. As the register drive-shaft rotates the flattened crankpin will advance the action of the valves 25, 26 at the reversal points in their movement compensating in this way for reduction of accuracy at high rates of flow.

Title: Sulfonating olefins with gaseous sulfur trioxide
Inventor: ECCLES RAYMOND DALE
IPC: C11D1/00
Filed: 1964-07-13
Abstract: Liquid light-duty and heavy-duty detergent compositions contain as the active ingredient a mixture of an n-alkene sulphonate and a gamma-hydroxy n-alkyl sulphonate, said mixture being prepared by hydrolysing and neutralizing the product obtained by sulphonating a C12- 20 olefin with SO3 under specified conditions (see Division C2). The cation of the neutralized sulphonates may be alkali metal (e.g. Na) or ammonium.  Additives which may be present include polyphosphates, e.g. potassium tripolyphosphate and tetrapotassium pyrophosphate, sodium silicate, hydrotropes, e.g. sodium xylene sulphonate, higher fatty acid alkanolamides, aliphatic tertiary amine oxides, sodium nonyl phenyl ether sulphonate, and carboxy-methyl cellulose.  Reference has been directed by the Comptroller to Specification 991,819.ALSO:A surface-active composition is prepared by (a) continuously introducing at a substantially uniform rate a gaseous mixture of from 0.1 to 10 parts by volume sulphur trioxide and correspondingly from 99.9 to 90 parts by volume of an inert carrier gas into a liquid charge of an essentially linear 12-20 carbon atom olefin maintained at a temperature not greater than 50 DEG  C. until not in excess of 1.1 mole of sulphur trioxide is reacted per mole of olefin, (b) and (c) hydrolysing and neutralizing the resultant reaction product with a water-soluble base and (d) recovering as the surface-active composition the sulphonate content of the resulting mixture. Either acid, neutral or basic hydrolysis is applicable and is preferably carried out at a temperature greater than 70 DEG  C.  Suitable inert carrier gases are sulphur dioxide, nitrogen, air, hydrogen or argon.  The olefins may be either terminally or internally unsaturated and especially suitable are those containing from 15-17 carbon atoms or mixtures of even-numbered carbon atom alpha-olefins which contain a substantial amount of 1-n-hexadecene and have an average molecular weight corresponding to that of said isomer. Linear unsymmetrical dialkyl olefins may also be used.  The initial product formed from the reaction of sulphur trioxide with a straight-chain mono-olefin is a mixture of an unsaturated aliphatic sulphonic acid and an alkyl gamma-sultone.  On hydrolysis the sultone content is converted to gamma hydroxy alkyl sulphonic acid and the surface-active composition consists therefore of a watersoluble salt of a mixture of gamma hydroxy alkyl and alkene sulphonic acids.  The sultone content of the sulphonation product may be isolated by neutralizing the sulphonation product, extracting with a light hydrocarbon such as pentane, hexane or heptane and then distilling off the hydrocarbon.  The surface-active composition may suitably be used in the preparation of heavy and light-duty detergent compositions (see Division C5).  Reference has been directed by the Comptroller to Specification 991,819.

Title: Improvements relating to the control of the relative flow of fluids to consuming appliances
IPC: F23D14/60
Filed: 1938-10-05
Abstract: 520,334. Fluid-actuated valves. DUDLEY, BRIERLEY HILL & DISTRICT GAS CO., and WHITE, A. H. Oct. 5,1938, No. 28843. [Class 135] A proportioning-device for regulating' the relative flow of fluids, such as gas and air, comprises interconnected valves which control the supply of the two fluids and are operated by the difference in pressure between the pressure. in one fluid and a pressure caused by that fluid after passing through a restricted bye-pass and being influenced by a restricted release. The passage of air from an inlet 3 to an outlet 4 is governed by a piston 7, which controls outlet passages 8. The piston is connected by a rod 28 with a second piston 27, which controls the passage of gas from an inlet 18 to an outlet chamber 15. A rotatable ported sleeve 20 adjusts the proportion of gas to air. A bye-pass 9 leads from the air-inlet below the piston 7 to the space above the piston through an adjustable restriction 31. The bye-pass communicates with the atmosphere through a release 11, controlled by an adjustable cock 12. The release 11 is first opened, so that the full air pressure is applied to the piston 7, which rises' and opens the inlet to the maximum. The quantity of air and gas supplied is reduced to any desired extent by partial closure of the release. This causes a pressure to be built up behind the piston 7, which descends until the air passing the restriction 31 equals in amount that escaping from the release.

Abstract: 445,694. Master control of motors; actuating controllers. BENNITT, W. B., Ivybank, Moss Lane, Ashton-on-Mersey, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Oct. 9, 1934, No. 28932. [Class 38 (iii)] Control apparatus for an alternating-current commutator motor 1 speed - controlled by movement of its brushes, comprises electrically operated clutch means 12, 13, between the brush-shifting gear 4 and a member 6 continuously rotated at least while the main motor is in operation, a controller 26 whereby the motor is energized and the clutch means selectively operated to cause the brushes to be moved to increase or decrease the speed or to be left in an intermediate position, and additional means 22, which are rendered effective only upon de-energization of the main motor, to bias the brushes to the minimum speed position. Movement of the controller to position I in the hoisting direction connects the main motor to the supply for hoisting operation and, if the brushes are not in the minimum speed position and limit switches 36, 37, are closed, a clutch coil 17 is energized to couple the brush-moving gear to a bevel pinion 8 and cause return of the gear to the minimum speed position. Movement of the controller to the position III in the hoisting direction causes energization of a clutch coil 16 so that the brush-moving gear is coupled to a bevel pinion 10 and moved to the full speed position, whereupon the limit switches 38, 39, are opened, the brushes may be held in an intermediate position by moving the controller to position II. Similar control is exerted for the lowering operation. The brush gear operating shaft 5 is provided with a crank 18 engaging a weighted crank 21 mounted by "free-wheel" mechanism 20 on a sleeve 19 freely mounted on the shaft 5. This sleeve is held fast by a brake 23 applied by a coil 24 for all on positions of the controller 26. During movements of the brush gear in a speed increasing direction the crank 21 is operated, the " free-wheel " mechanism permitting this operation but preventing return movement when the brushes move in a speedreducing direction. When the controller 26 is moved to its " off " position, the coil 24 is de-energized to release the crank 21 which falls under the influence of the weight 22 and returns the brush gear to the minimum speed position. The member 6 may be driven by a pilot motor which may be reversible, or, as shown, from the shaft of the motor 1. Specification 210,236, [Class 38 (iii)], is referred to.
