Title: Improvements in or relating to the distillation of tall oil
IPC: C09F1/00
Filed: 1946-08-19
Abstract: <PICT:0640244/III/1> Tall oil is separated into a fatty acid fraction and a resin acid fraction by submitting the tall oil, preferably after removal of its low-boiling constituents, to fractionation under sub-atmospheric pressure.  The main fatty acid fraction is withdrawn from the fractionation as a liquid side-stream; while the resin acid is withdrawn as liquid bottoms.  Tall oil was fed through line 10 into heat exchanger 11, and then introduced into fractionating tower 13 which was connected through condenser 16 with a vacuum pump, and supplied with live steam through line 19. The top of the tower was maintained at 375 DEG  F. and 35 mm.; the bottom at 475 DEG  F. and 65 mm.  The overhead vapours were condensed in condenser 16, and three-quarters of the condensate was returned to the tower as reflux. Tall oil free from low-boiling constituents, was withdrawn from tower 13 through line 20, and introduced into fractionating tower 21.  The top of tower 21 was maintained at 375 DEG  F. and 4 mm.; the bottom at 545 DEG  F. and 40 mm. The overhead vapours taken off through line 25 were condensed in condenser 26, and a large percentage of the condensate (equivalent to a reflux ratio of 14) was returned to the tower.  The main fatty acid product was taken off the fourth tray from the top of the tower, and was withdrawn through line 37.  Resin acid was withdrawn from the base of tower 21 through line 29 and introduced into flash chamber 30 which was maintained at 550 DEG  F. and 5 mm. The vapours from the flash chamber were condensed in condenser 32 to give the resin acid product.  Both flash chamber 30 and tower 21 were supplied with small quantities of live steam.

Title: Improvements in or relating to the production of leaven and leavened dough
IPC: F16K3/312
Filed: 1934-08-27
Abstract: A product for addition to dough to improve fermentation, is prepared by fermenting milk or the products of the treatment of milk with souring bacteria and allowing it to act, for a period of time of the order of 3 to 15 hours, upon farinaceous materials such as wheat flour, potato flour or leguminous meal, which has been decomposed or split by heating in an aqueous medium.  Yeast, hops, casein, albumen, malt meal, vitamin meal produced from sprouting corn, substances rich in diastase, malt extract, glucose, honey and nutritive salts may be added to the decomposed farinaceous material.  The sour milk may be derived from fresh milk, evaporated milk, whey, or milk products in solid, liquid and semi-liquid state.  In an example, the milk is pasteurized and then cooled and treated with curdling bacteria. After two hours fermentation, the milk is cooled to a temperature of 10-12 DEG  C. and stirred to a cream-like mass.  About 10 per cent of decomposed flour is added and the mixture allowed to interact for about 15 hours.  The whole is then stirred to a cream-like mass with the addition of one part by weight of yeast.  The product can be used in this form, or, after removal of water (preferably in vacuo) in the form of a partially dry, paste-like, or entirely dry pulverized condition.  The drying may be effected by atomization or by revolving driers, preferably at 60 DEG  C. or below.  In making bread with ordinary leaven, a portion of the product may be incorporated in the fresh leaven and the remainder in the final leaven.  In another example, the farinaceous material is decomposed by heating in milk, and, after cooling, a pure culture of sour milk is added. Interaction is allowed to proceed for about 3 hours.

Title: Improvements in and relating to gas turbines
Inventor: ROSS PETER MCGREGOR
IPC: F01D17/08
Filed: 1955-08-30
Abstract: 823,933. Gas-turbine plant. PARSONS & CO. Ltd., C. A. Nov. 6, 1956 [Aug. 30, 1955], No. 24877/55. Class 110 (3). [Also in Groups XI and XXXV] Means for limiting and, if desired, indicating any difference in outlet temperatures between two combustion chambers in a gas-turbine plant having more than one combustion chamber comprises one or more thermocouples in one combustion chamber outlet connected to one or more similar thermocouples in the other combustion chamber outlet so that the voltages set up oppose one another, any difference in the voltage being communicated to an electrical voltage-sensitive device which adjusts the fuel valve to maintain within limits equality of combustion chamber outlet temperatures. Thermocouples 1 to 4, located in the outlets 5, 6 of the combustion chambers 5a, 6a, are connected in series so that the voltage of the thermocouples 1, 2 in the combustion chamber 5a opposes that of the thermocouples 3, 4 in the combustion chamber 6a. Any difference in these voltages is communicated to a galvanometer 7 having two sets of contacts 8, 9 which are normally kept open. The contacts 8, 9 are connected, through relays 10, 11 if necessary, to a reversible electric motor 12 which drives a screw 13 to actuate a plunger 14 controlling the proportions of the fuel supplied through pipe 14a to the ports 15, 16. When the temperature at the outlet of one combustion chamber exceeds that of the other by a predetermined amount, one set of the contacts 8, 9 are closed so that the motor 12 actuates the plunger 14 to restore the balance of temperature. A reduction gear may be placed between the motor 12 and screw 13. The plunger 14 and ports 15, 16 may be arranged so that it is not possible to cut-off entirely the fuel supply to either burner. If more than two combustion chambers are provided, a number of systems would be needed. A similar system may be provided to give a warning signal for a temperature difference of say 40 ‹ F. or more in the event of failure of the temperature difference limiting system.

Patent GB-869266-A (GB)
Title: Improvements in non-linear amplifier circuits
Inventor: COHEN CHARLES L
IPC: G06G7/25
Filed: 1958-12-22
Abstract: 869,266. Valve limiting circuits. ACF INDUSTRIES Inc. Dec. 22, 1958, No. 24919/60. Divided out of 869,265. Class 40(6) [Also in Group XXXIII] An amplifier circuit having a non-linear input/output characteristic is shown. In Fig. 5, a conventional phase inverting amplifier 50 has an input terminal 52 and output terminals 54. A feed back lead 56 from one output terminal is connected to the junction 58 of a diode pair 60, 62 connected to terminal 52 through equal resistors 64, 66 respectively. The input signal is fed from terminal 68 over resistor 70 to terminal 52. A transformer 72 has its primary winding 71 energized by a reference source of the same frequency and phase as the signal on terminal 68 and its secondary winding is grounded at a centre tap 75 and connected across terminals 74, 76, as one diagonal of a bridge comprising diodes 78, 80, 82, and 84. The other diagonal of the bridge is connected across diodes 60 and 62. Assuming that there is no signal on terminal 68, the diode bridge 78-84 acts as a full wave rectifier and back-biases diodes 60 and 62 with a reference voltage, and the diodes thus cannot conduct. The symmetrical position of terminal 52 ensures that it remains at ground potential. Thus amplifier 50 has no input signal and no output signal. If now a signal is added at terminal 68, an amplified signal appears on lead 56. If this amplified signal is less than the reference voltage maintained across diodes 60, 62, the latter remain non-conducting, and no feed back from lead 56 reaches terminal 52. The amplifier thus operates at its maximum gain. When the feed back signal on lead 56 exceeds the back-bias on diodes 60, 62, each diode conducts on the appropriate half cycle. For example, during one half cycle diode 62 conducts, and back-biases diodes 82, 84, which now do not conduct. Thus the feed back voltage is fed to terminal 52 over resistor 66. Diodes 78, 80 continue to conduct, and the reference voltage is fed to terminal 52 over resistor 64. Since the feed back voltage is greater than the reference voltage, there will be a resultant potential at terminal 52. On the other half cycle, diodes 78, 80 are back-biased, and diodes 82, 84 conduct, and a resultant potential again appears at terminal 52, which is thus fed with a resultant A.C. feedback signal. The gain of amplifier 50 thus drops to a value depending on the impedance of the feed back network and the input impedance of amplifier 50. A graph of relationship between the signal on terminals 54 and that on terminal 68 is shown in Fig. 6, and comprises a very steep portion passing through the origin, and two linear portions of lesser slope. In a modification, a feed back resistor is connected between lead 56 and terminal 52, to lessen the slope of the steep portion of the graph in Fig. 6.

Abstract: 1501325 Testing ignition systems of IC engines GUNSONS COLORPLUGS Ltd 16 June 1976 24937/76 Heading G1U The dwell angle of the points of an I.C. engine ignition system is measured by connecting the points in series with the battery and a resistor and by using a meter arrangement as shown in Fig. 3 to compare the current that flows when they are closed with the average current that flows when they are repeatedly operated by rotation of the engine. In use the meter arrangement is first connected across the battery Fig. 4 (not shown) and a variable resistor is adjusted to achieve full scale deflection whilst the engine is being rotated by the starter motor. The meter arrangement is then connected in series with the battery and the points Fig. 5 (not shown) and the deflection achieved whilst the engine is again rotated by the starter motor is noted. The reduction in the deflection is indicative of the dwell angle.

Title: Improvements in or relating to impulse ratio correction circuits
IPC: H04M3/24
Filed: 1956-08-15
Abstract: 816,911. Automatic exchange apparatus. GENERAL ELECTRIC CO. Ltd., and TAYLOR, H. B. Aug. 15, 1957 [Aug. 15, 1956], No. 25009/56. Class 40 (4). To produce impulses more in accordance with a desired make-to-break ratio the impulses are repeated by a relay RC, one of the windings of which is in series with a capacitor to delay operation in response to an impulse and to delay release which is initiated as soon as the relay operates, the relay being released on receipt of the next impulse if this occurs before the end of the delayed release time. As shown in the drawing to the Provisional Specification, relays A, AA and B respond to a calling cond.ition, A and AA falling back to each impulse while B holds back during the call. At the beginning of each impulse RC is energized differentially by earth over a2, RC operating when capacitor 7 is sufficiently charged to draw insufficient current through winding 11 to counter current in winding 10. Capacitor 7 discharges over windings 10 and 11 in series and the outgoing loop is broken when RC responds. For impulse frequencies of 7 to 10 per second capacitor 7 dissipates its charge to release RC before the next impulse. For impulse frequencies from 10 to 14 per second the next impulse arrives to break the discharge circuit releasing RC and leaving a residual charge on the capacitor which causes RC to operate earlier to the impulse. At the end of a call A and AA fall back while B releases slowly, in which time RC may operate and release itself one or more times to the disturbance of the outgoing line. To avoid this the circuit shown in the drawing to the Complete Specification provides an energizing circuit over resistor 12 so that once operated at the end of a call RC remains held until B releases. This energizing circuit is connected between the operation of RC in response to an impulse and the end of the impulse when A re-operates, but as the connection is made during the early discharge time of capacitor 7 the effect of holding RC only becomes appreciable for long impulses of low frequency.

In yarn inspection apparatus comprising a catcher, clearer or cleaner normally detecting defects e.g. slubs, arising from yarn portions of enlarged diameter in a running yarn and initiating a signal, a stop-motion or corrective action, the transfer of yarn feed from one bobbin to another causes the yarn to be diverted from its normal path for sufficient time to ensure that a transfer or tie-in knot in the yarn is not engaged by the catcher &c As shown, the shift of a yarn from bobbin 16 to reserve bobbin 11 (and thence through a tensioner 20 and guide rod 32) causes yarn adjacent a transfer knot 17 to pivot a bar 25 into engagement with a curved bar 26, thus momentarily completing a circuit to and energizing a solenoid 42 the armature of which, through a link 43, pivots an arm 22 to lift the yarn, passing through an eyelet therein, into the position shown chain-dotted i.e. clear of the narrow portion of a flared opening 33 formed by clearer plates 28.

Abstract: 259,608. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning), Oct. 10, 1925, [Convention date]. Benzanthronylsulphides are produced by treating halogen benzanthrones with hydrogen sulphide, sulphur, or other sulphurizing agent from which sulphur or a reactive sulphur compound is eliminated during the reaction; thiosulphates, thiocarbonates, hydrosulphites, and carbon disulphide are mentioned; in some cases an addition of an acid binding agent such as sodium acetate or pyridine is advantageous. The use of metal sulphides, hydrosulphides, and polysulphides and the treatment of nitrohalogenbenzanthrones with sulphur is excluded. According to examples Bz1 : Bz1<1>-benzanthronylsulphide is obtained by heating Bz1-brom-benzanthrone with sulphur, sodium thiosulphate, potassium xanthate, or sodium hydrosulphite and acetate, in trichlorbenzene or tetrahydronaphthalene; or with sulphur, copper bronze, sodium acetate, and alcohol; the Bz1- brombenzanthrone may be replaced by Bz1- chlorbenzanthrone : a dibrom-Bz1 : Bz1<1>-benzanthronylsulphide is similarly obtained from dibrombenzarthrone (Specification 20837/06). Specifications 15979/11 and 256,059 are referred to.
