Patent GB-999461-A (GB)
Title: Improvements in and relating to the production of alcohols
Inventor: COX GRAHAM FREDERICK
IPC: B01J21/02
Filed: 1962-05-14
Abstract: Ruthenium carbonyl may be produced by heating a solution of a ruthernium salt of a monocarboxylic acid (e.g. stearic) in an inert organic solvent, e.g. a hydrocarbon to 200 DEG  C. under a mixture of equal volumes of hydrogen and carbon monoxide at 240 ats., and then under the same conditions of temperature and pressure, with carbon monoxide alone.  The precipitate formed is filtered under a nitrogen atmosphere, and the filtrate is concentrated to the desired bulk under a carbon monoxide atmosphere.ALSO:Alcohols are made from olefines by a process which comprises bringing a straight or branched chain aliphatic mono-olefin containing at most 10 carbon atoms and preferably at most 4 carbon atoms, carbon monoxide, water and a base compound, defined as a compound of one of the elements of Group Vb of the Periodic Table, for example nitrogen or phosphorus, each of which is in the trivalent form and each valency of which is attached to a carbon atom, into contact at elevated temperature and pressure with ruthenium carbonyl.  It is preferable that the ruthenium carbonyl is produced in situ from a ruthenium salt of an aliphatic monocarboxylic acid.  The preferred basic compound is trimethylamine.  The process may be carried out in the presence of an inert organic solvent such as a hydrocarbon or an alcohol containing up to 4 carbon atoms. Examples of other suitable bases include N-n-butylpyrrolidine and tri-n-butylphosphine.  In Example 1 a solution of ruthenium stearate in a petrol is heated under pressure of a mixture of equal volumes of hydrogen and carbon monoxide and thereafter under a pressure of carbon monoxide only. The product is filtered under a nitrogen blanket and the precipitate is washed with petrol.  The filtrate and washings are bulked and the liquid is evaporated under a carbon monoxide atmosphere.  To this solution there are added trimethylamine, water and methanol, together with propylene and the reaction mixture is heated under a pressure of carbon monoxide.  From the reaction product n-butanol and isobutanol are obtained.  In another example ruthenium stearate, trimethylamine, water, methanol and propylene are heated together at elevated temperature under pressure of carbon monoxide.  From the reaction product n-butanol and isobutanol are isolated.  In other examples ruthenium carbonyl as such is used as the catalyst and the bases employed are trimethylamine n-n-butylpyrrolidine and tri-n-butylphosphine.

Abstract: 530,547. Refrigerating. INGERSOLL-RAND CO. June 27, 1939, No. 18673. Convention date, July 14, 1938. [Class 29] Vacuum systems.-Liquid seal devices are provided between main and auxiliary evaporator chambers 6, 8 of a system having separately controlled steam-jet exhausters 9 discharging to a condenser 13, so that when any evaporator chamber is rendered -inactive by shutting off the steam supply to its exhauster, the refrigerant (water) flows only to the active evaporator. The cooled liquid is withdrawn from the bottom of the evaporators through risers 17, 18 connected to a pipe 16 and circulating pump 16a, the risers ensuring retention of liquid in the pipes at all times. The liquid to be cooled enters through a pipe 37 at the bottom of liquid seals 23, 33 formed by a depending baffle 5 and weir overflows 24, 32, the former being higher and discharging into evaporator chamber 6, while the latter is adapted to discharge into further seals 34, 28 of lesser height formed by a depending baffle 7 and a weir 29. The riser 17 is connected with a seal formed by a weir 20 and baffle 21 in a space maintained at condenser pressure by a pipe 22, and the space between the baffles 5, 7 is maintained at condenser pressure by a branch pipe 35. Deflecting plates 27, 31 are placed over the weir discharges to intercept spray and prevent it from entering the exhaust ports 10. When both chambers are active the incoming liquid flows over weir 24 and from the chamber 6 through a byepass passage 36 below the seals 23, 33 to seal 28 and over weir 29. If chamber 8 is rendered inactive it immediately assumes condenser pressure and liquid ceases to flow through seal 28. Cooled liquid leaves chamber 6 by seal 19 and riser 17. If chamber 6 is shut down and chamber 8 kept active, liquid flows by seals 33, 34, 28 &c. over weir 29 to chamber 8 only, and is discharged through riser 18. If both are shut down, incoming liquid passes to seal 34 and flows through byepass 36 and chamber 6 to the outlet 17 with little or no heating- up of the liquid.

Abstract: 1,138,082. Shaft position encoders. ROLLS ROYCE Ltd. 19 April, 1967 [28 April, 1966], No. 18700/66. Heading G4H. Position measuring apparatus comprises a translucent cylinder on which is formed a diffraction grating with lines at an angle to the cylinder axis, and means to direct light through diametrically opposite sides of the cylinder to form a moirÚ fringe pattern. The position of the pattern may be directly indicative of the angular position of the cylinder, Fig. 1, (not shown). The position may be measured by counting the fringes with a photocell and a counter. Angular movements of a shaft 57, Fig. 2, may also be measured by a grating 44 on a cylinder 43 continuously rotated by a motor 51. Light from a source 45 is collimated by a lens 46 and passes through diametrically opposite portions of the grating 44. The rulings of the grating are inclined to the axis of cylinder 43 so that fringes are produced and detected by a bank of photocells 47. The cylinder 43 has a slot 53 which allows light to pass once per revolution from a source 56 to a fixed photocell 64 and a photocell 62 connected to the shaft 57. Photocells 64 and 62 respectively open and close a gate transferring pulses from the photocells 47 to a counter. The count recorded is thus proportional to the angular separation of cells 62 and 64.

[Also in Group XL (c)] A phase discriminator for determining the in-phase or quadrature phase state or component of an A.C. signal A cos wt. +B sin wt. relative to a reference A.C. wave of equal frequency and predetermined phase comprises time controlled impedances 3, 7 controlled by the reference wave and an energy storage device, e.g. capacitor 5, between the impedances 3, 7. The latter may be alternately operated short circuits to earth made by a switch 8 (Fig. 2), synchronously operated from the reference source 12 by way of a phasing network 13 so that only half-cycles of the input component A cos wt. pass to the capacitor 5. This, across a resistor 6 produces an output signal as shown in Fig. 6c, due to the average D.C. output being zero, so that only the portion Y proportional to A is passed to the output 2 when subsequently the input is short circuited and the output shunt is open circuited. To determine the phase quadrature component B if any of the input wave the switch 8 is driven in phase quadrature. In each case the component in phase quadrature with the component desired to be accepted produces zero output from the capacitor 5 or storage device. The system may include an amplifier A. In modifications two pairs of triodes or diodes connected in parallel opposition constitute the input and output short-circuiting switch 8.

IPC: G11B17/16
Filed: 1919-07-29
Abstract: 153,087. Wadsworth, H. L. July 29, 1919. Phonographs.-A coin-controlled sound-recording machine is adapted to make a sound record upon a blank tablet, to reproduce it so that the speaker may verify his utterance if desired, and to deliver the table outside the machine, all the operations taking place automatically in proper sequence. Fig. 2 is a plan view of the machine with the parts above the turntable removed, and Fig. 5 is a vertical section. The machine is started by inserting a coin through the channel 145, Fig. 5, from which it falls into a verticallymovable tube 147. A plunger 153 is then depressed by a handle 156 and engages the coin, depresses the tube 147, and causes a cross-pin 147<a> to rock a lever 161, which thereupon rides over and rests upon an arm 162, thus completing the circuit of the motor 4. The coin escapes into a receptacle 159. By inserting a pin 172 across the upper end of the tube 147, the machine may be started without a coin. The motor 4 drives the machine and also actuates the mechanism for controlling the above-mentioned operations. The record is finally delivered by a cam 137, Fig. 2, operating a rack 138 and rotating a pinion 141 on a vertical shaft 142, which carries at its upper end an arm 143. This arm engages the rim of the record and forces it between guides 144 an to a shoot 3<b> by which it is delivered through the casing. The recording and reproducing periods are indicated to the speaker by a pointer 171 moving over a dial 170, Fig. 5, on the front of the machine. The pointer is geared to the shaft 40, and indicates when the sound-boxes are in position for recording and reproducing.
