Title: Improvements in the production of approximately neutral or reducing atmospheres containing carbon dioxide and carbon monoxide and in apparatus therefor
IPC: C01B32/40
Filed: 1935-04-16
Abstract: 455,436. Furnace atmospheres. BRAYSHAW FURNACES & TOOLS, Ltd., BRAYSHAW, S. N., and RUSHTON, F., Belle Vue Works, Boundary Street, Manchester. April 16, 1935, Nos. 11684 /35 and 740/36. [Class 51 (ii)] In the production of approximately neutral or reducing atmospheres charcoal is burnt with a controlled quantity of air, and the composition of the atmosphere is maintained constant by using the indications of a CO or CO2 testing apparatus for regulating automatically one or more of the factors producing the atmosphere. In the plant shown in Fig. 1, partial combustion of charcoal is effectedin the producer A with air supplied by the pipe a<1>, and combustion of the resulting gas to produce the desired atmosphere gas takes place in the chamber C<1> with air from the pipe c. An intake e in the flue D<2> leads to a gas analyzer E, and the indications given control a motor E<1> which operates a valve E<2> in a byepass c<4> across a valve c<3> in the pipe c. The air supply may be passed through a drier A<2> and an exhaust pipe a<4> is provided for use in starting up. The chamber C<1> may be integral with the producer. In a modification, Fig. 2 (not shown), the secondary combustion chamber is arranged beneath the furnace chamber in which the atmosphere is used, and the furnace temperature is maintained constant by a pyrometer control acting on the air supply. In another form, composition of the atmosphere is controlled by passing a variable portion of unburnt gas from the pipe a<3> into the flue D<2> carrying the burnt gases from the combustion chamber C<1>. In further modifications, Figs. 3 and 4 (not shown), the gas from the combustion chamber C<1> is passed through a body of heated carbon and the control is effected by varying the temperature in a combustion chamber surrounding the carbon container. The gas burnt to heat the carbon may be supplied from a separate source or may be the gas from the charcoal producer, the products of combustion in the latter case first heating the charcoal container externally, and then being passed through the container. In another form, Fig. 7, in which the products of combustion are passed through heated charcoal, the temperature of the chamber G<1> around the carbon container G is controlled by an automatically operated valve G<2>, which determines the proportions of combustion products which pass to the chamber G<1> and to a byepass g<3> respectively. Specifications 455,276 and 455,486 are referred to.

Title: Apparatus for measuring and transmitting a condition from a rotatable member
IPC: G01L3/10
Filed: 1946-04-16
Abstract: 615,920. Electric systems for measuring strain. BALDWIN LOCOMOTIVE WORKS. April 16, 1946, No. 11740. Convention date, May 26, 1945. [Class 40 (i)] An electrical system for measuring strain of a rotatable member comprises two pairs of inductively associated windings 25, 26 and 32, 34, Fig. 1, windings 25, 34 being stationary and windings 26, 32 rotating with the shaft 10, the input A.C. being applied to winding 25 and the output being taken from winding 34, the effect of windings 25, 26 on the output being counteracted. As applied to a torque-measuring device, A.C. from a source 38, Figs. 1, 2, is applied to a stationary primary winding 25 of a transformer, whose secondary 26 rotates with the shaft 10 and feeds a Wheatstone bridge 20 composed of strain gauges 21 ... 24, Fig. 2, secured at 45 degrees to the shaft so that torque due to a load 18 produces an elongation of one pair and a compression of the other pair; the out-of-balance current is applied to the primary 32, which rotates with the shaft 10, of a transformer whose secondary 34 feeds a measuring instrument 36. To eliminate coupling between transformers 25, 26 and 32, 34 over the shaft 10, a stationary winding 40 is energized from the source 38 with A.C. of adjustable phase and amplitude and is positioned on the shaft 10 so as to produce an equal and opposite effect on transformer 32, 34 to that produced by transformer 25, 26. In a modification, transformer 25, 26, Fig. 3, feeds two bridges 20, 55, one for measuring torque and the other for measuring axial thrust, and a single compensating coil 40 can be alternately energized over switch 58 to compensate the field of transformer 25, 26 on either of transformers 32, 34 or 56, 57. In a further modification, Fig. 4, the secondary winding 34 is fed with A.C. from source 38 of adjustable phase (by adjusting condenser 42) and adjustable amplitude (by adjusting resistance 41) so as to be equal and opposite to the voltage induced by the transformer 25, 26; further, short-circuited single-turn windings 71, 72 may embrace the shaft 10 to reduce flux through it, and the same result is obtained by shields 73, 74 of magnetic material, while copper shields 75, 76, 77, 78 may be provided to give electrostatic shielding. Specification 549,140 is referred to.

Patent GB-606265-A (GB)
Title: Improvements in or relating to polyphase electric motor controllers
IPC: B66C13/26
Filed: 1945-05-15
Abstract: 606,265. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. May 15, 1945, No. 12165. Convention date, May 17, 1944. [Class 38 (iii)] A polyphase motor is connected so as to unbalance the primary and give braking torque at zero speed and impedance in the primary circuit is subsequently varied to reduce the braking action and give a reversal of the torque at zero speed. The invention is described as applied to a 3-phase slip-ring induction motor for hoisting, controlled by a hand-operated drum controller. Movement of the controller through its hoisting positions connects the motor primary terminals to the supply terminals L, L2 and L3 and progressively shortcircuits secondary resistance in ordinary manner. In the first lowering position the terminal L1 is connected (as in Fig. 2) to the motor primary terminal T3 through an impedance PR1-PR2, and is connected directly to the terminal T1 through switch contacts. Terminal T2 is connected to terminal L2. The voltages at terminals T1, T2 and T3 are represented respectively by vectors O1, 02 and O3 in Fig. 2a. On the next and subsequent steps, with impedance PR1-PR2 short-circuited, the further impedance PR2-PR4 is inserted, in steps, between terminals L1 and T1 and then terminal T1 is connected also to terminal L1 through another impedance PR5-PR6, as shown in Fig. 5. The effect of these steps is to reverse the phase rotation by interchanging the phase relationship of vectors O1 and 03 and progressively increasing the phase angle between them. Up to this stage a part of the secondary resistance is short-circuited. On the next step the impedance PR2-PR4 is disconnected (as in Fig. 6) and all the secondary resistance is brought into circuit; lastly, the impedance PR5-PR6 is short-circuited so that the motor is connected directly across the supply for running in the lowering direction. On the first lowering step there is a small opposing (i.e. hoisting) torque at zero speed which increases with increase of speed as the load runs down. On the next step there is a very small lowering torque at zero speed and, on subsequent steps, a lowering torque which increases to full-load torque on the last step; in each case this lowering torque decreases and ultimately reverses with increase of speed. A brake-releasing coil may be connected across terminals T2 and T3. The drum controller may energize the operating coil of a main circuit-breaker on movement to a lowering or hoisting position, and a limit switch may be included in the hoisting positions. Some other type of mechanical controller, or electromagnetic switches, may be used instead of the drum controller. Specification 583,820 is referred to.

Title: Improvements in and relating to the synthesis of esters
IPC: C07C51/10
Filed: 1947-05-07
Abstract: Esters of carboxylic acids are obtained by reacting under pressure at 100-325 DEG  C., preferably 200-300 DEG  C., an alcohol, or an ether, or a mixture thereof, with carbon monoxide, in the presence of a cobalt or nickel salt of an aliphatic organic mono-carboxylic acid as catalyst.  Pressures instanced range from 200 to 1500 atms., and are preferably 400 to 1000 atms.  The presence of hydrogen favours the reaction and quantities of catalyst used range from 2 to 10 per cent based on the total weight of the liquid reaction mixture.  Alcohols specified are ethanol, isopropanol and methanol, which is preferred. Ethers specified are dialkyl ethers.  When methanol is treated the hydrogen and carbon monoxide required may be obtained in situ by the decomposition of further quantities of methanol and in the production of methyl acetate from methanol the concentration of carbon monoxide to hydrogen is in a molar ratio of 3 to 1.  In examples: (1) and (2) methanol is treated at elevated temperatures and under pressure with carbon monoxide and water in the presence of cobalt acetate as catalyst to yield methyl acetate; (3) and (6) are similar except that the reaction is effected in the presence of added hydrogen and in one instance in (6) dimethyl ether is also present; and in (4) and (5) dimethyl ether is treated at elevated temperatures and under pressure with carbon monoxide and water in the presence of iodine as reaction promoter and nickel acetate as catalyst obtained in situ by the decomposition of nickel carbonyl to give methyl acetate and acetic acid.
