Patent GB-884620-A (GB)
Title: A process for the purification of alpha-beta, unsaturated aliphatic aldehydes
Filed: 1960-07-22
Abstract: One or more saturated aliphatic aldehydes are removed from an a ,b -unsaturated aldehyde containing minor proportions of the saturated aldehyde(s) by contacting the mixture with a catalytic amount of an aluminium alcoholate under substantially anhydrous conditions at a temperature below 50 DEG C. and separating the purified a ,b -unsaturated aldehyde from the mixture.  The process is particularly suitable for the purification of acrolein and methacrolein containing minor proportions of saturated aldehydes having similar boiling points.  Suitable aluminium alcoholates are those of methyl, ethyl, propyl, isopropyl, isobutyl and allyl alcohols and of 4-methyl-pentanol-2 and cyclohexanol, and those in which the alkoxide groups are dissimilar.  The aluminium alkoxide is, in general, used in an amount not exceeding 1 mol %.  Under the above conditions the saturated alcohol undergoes self-condensation and, to some extent, reaction with the unsaturated aldehyde with the formation of higher boiling reaction products consisting essentially of mixed esters. The unsaturated aldehyde may then be readily separated from the mixture, for example by decantation, stratification or distillation. Examples are given of the purification of acrolein, containing propionaldehyde and acetaldehydes as impurities, by treatment with aluminium secondary butoxide.

Filed: 1929-08-23
Abstract: 333,748. Cincinnati Bickford Tool Co., and Williamson, L. R. Aug. 23, 1929. Drilling - machines. - A metal-cutting machine having a movable drill-arm carrying a driving motor and operating-mechanism for the drill driven therefrom has a fluid pump actuated by the operating-mechanism so as to supply fluid to clamping means for the drill-arm and also to the operating or other mechanism for the lubrication thereof. As applied to a radial arm drilling-machine the arm 13 is vertically slidable on a sleeve 12 which is rotatable on a pillar extending upwards from the base 10. An electric motor 16 on the arm drives, through a shaft 17 and gearing 19, a shaft 20 journaled on the arm, the shaft 20 being splined to the driving gearing for the drill spindle located in the head 14 and having secured to one end thereof a pinion 21. Gearing 23 in mesh with the pinion 21 drives a crank shaft 24 carrying eccentrics for operating a two-cylinder oil pump 36 whose inlet valves lie beneath the level of oil in a casing 26 enclosing the pump and gearing. Oil is delivered from the pump by a pipe 37 to a distributing valves 55 whose plug 63, Fig. 5, is rotatable through bevel gearing 77, Fig. 4, and a shaft 59, Fig. 1, on the arm from a hand lever 58 which is splined to the shaft 59 and is carried along with the drill head 14 by means of a lug 62 thereon engaging an annular recess 61 on the lever. The supply pipe 37, Fig. 5, leads oil through an annular recess in the valve plug 63 to an axial bore 68 from which it proceeds through a. radial passage 69 to either of the pipes 72, 73 which are connected to the opposite ends of a fluid pressure cylinder 38, Fig. 4. The plunger 44 of the cylinder carries a sleeve 46 formed with rack teeth 47 engaging a toothed lever 49 splined on a vertical shaft 50 journaled on the sleeve 12 and provided at 52, Fig. 1, with an eccentric for operating a clamping bolt for the split end 51 of the sleeve to clamp it to the interior pillar. The packing 45 for the plunger 44 is provided with channels 45a to lead the oil directly to the flexible part of the packing to ensure tightness. A pipe 83 leads to the top of the casing 26 and is supplied from the exhaust pipe 74 of the cylinder 38 (leading from an annular recess 65 in the valve plug), or from a bye-pass relief valve 79 on the supply pipe 37 to the cylinder. The valve plug 63 may be set to close both pipes 72 and 73, in which case the clamp 52 is maintained in either its clamped or unclamped condition and all the supply from the pump is delivered through the relief valve 79 to the pipe 83 and thence is sprayed over the gearing or is led to any other part of the machine requiring lubrication. Alternatively the pressure supply may be left in communication with either end of the cylinder, or with both ends. When the cylinder is in use, it absorbs substantially the whole output from the pump but this subsequently passes to the lubricating pipe 83 by means of the exhaust 74 from the cylinder.

Abstract: 1532906 Controlling variable displacement pumps ROBERT BOSCH GmbH 22 June 1976 [15 July 1975] 25969/76 Heading G3P In a combustion engine 25 driving a variable displacement pump 10 a member 27 determining engine fuel supply co-operates with an electrical means, such as switch member 28, when the engine is at or near full power, to control a valve 34 controlling pressure-responsive means for adjusting the displacement-changing member 13 of the pump. In position I of the valve 34, to which it is urged by spring 34', both small and large-area bores 17, 18 are connected to the pump output so that the member 13 is urged to the maximum displacement position by piston 16; a pressure drop across throttle 36 urges, via lines 37, 38, the vlave to position II in which the bore 18 is isolated from the pump output. If as a result of increased load the engine fuel supply is increased to give maximum torque, switch 28 closes, energizing electromagnet 31 to shift the valve 34 to position III; a pressure drop across throttles 36, 40 urges the valve to position II. The valve may provide for throttled flow between its three positions. The fuel control member 27 may act on a position transducer (47), Fig 2 (not shown), whose signal is differentiated and the resultant used to control the electromagnet 31 so that the time taken for the valve 34 to be actuated is less the faster the member 27 is moving towards maximum torque position.

Filed: 1947-09-25
Abstract: 629,726. Control of two-motors. SAUNDERS-ROE. Ltd., and PIRIE, R. A. Sept. 25, 1947, No. 26036. [Class 38(iii)] [Also in Group XXXIII] A power-operated flying control system with a pair of motors arranged to drive a power shaft though a differential gear is provided with a safety device which remains ineffective so long as the motor shafts rotate in the same direction, but is rendered operative, by rotation of the shafts in opposite directions, to give a warning signal or to stop the failed motor. The invention is shown applied to a control system of the kind described in Specification 619.984, [Group XXXIII], in which a torque shaft 10 is driven through a differential 11 by a pair of hydraulic motors 12, 12a, the latter being driven by variable-delivery pumps 13, 13a, which are operated by continuously running electric motors 14, 14a. The electric motors are controlled by a pilotoperated lever 15 through Selsyn transmitters 18, 18a and receivers 19, 19a. Pinions 42, 42a on the output shafts of the hydraulic motors 12, 12a mesh with pinions 43, 43a having screw thread connections 47, 47a with reciprocating members 44, 44a. Normally, these latter members are held in their neutral positions by pairs of centering springs 46, 46a. Movement of the control lever 15 to initiate operation of the control surface results in closure of one of two switches 50, 50a, and movement of both members 44, 44a in the same direction to close a pair of micro-switches 48, 48a or 49, 49a, the axial movement of the members 44, 44a being limited by the disengagement of the threaded portions 47, 47a. In the event of failure of one of the motors its shaft is rotated in the reverse direction through the differential 11, causing its associated member 44 or 44a to move in the opposite diection to close the previously open switch and the circuit of the appropriate signal lamp 52 or 52a. Instead of, or in addition to the signal lamps, the circuit may include solenoids 54, 54a operating switches 55, 55a controlling the electric motors 14, 14a, so that the motor which fails may be switched off automatically. Additional devices may be provided to indicate unequal motor speeds, the arrangement shown comprising dynamos 26,26a driven by the respective motors, and connected in a bridge circuit with a galvanometer 29 on the pilots' control panel. Alternatively, centrifugal governors may be substituted for the dynamos, the governors controlling variable resistances in a bridge circuit, or switches operating signal lamps, Figs. 3 and 4 (not shown).

[Also in Division D1] A web F being wound up on a reel 1 passes over rollers 2, 3, 4, the roller 4 rotating on an axis 4a on arms 4c pivoted at 4b to a disc 5 rotatable on an axis 5a eccentric to the roller 3. Clockwise pivoting of the arm 4c is limited by an adjustable stop 19 engaging the disc. During normal operation, increase in web tension due to increased diameter of the reel 1 pulls the roll 4 downwards and moves the disc 5 clockwise, thereby through a chain 6 rotating a wheel 8 and shaft 7 counter-clockwise. The rotation of the shaft 7 controls a valve 16 to reduce the web winding speed and restore the tension to its original value and the roller 4 to its original position. The movement of the shaft 7 is opposed by a piston 11 set for the required tension by a valve 14. The weight of the roller 4 is balanced by a counter-weight 23. If the web is severed, for example at T, the piston 11 causes the disc 5 to rotate counterclockwise so that the roller 4 is jammed against the roller 3 as shown in chain lines to prevent backward feed of the web.

Abstract: 1, 094, 397. Measuring pressure electrically. HOCHVAKUUM DRESDEN VEB. June 21, 1965, No.26153/65. Heading G1N. A cold cathode ionization manometer tube 5 is connected to a high tension source 1 through a switch 4 providing two different circuit arrangements for pressure above and below about 10 Torr. Initially the switch is in position a and tube 5 and capacitor 3 act as a blocking oscillator. The oscillations are amplified at 7 and passed to a grounded-anode stage 8, the output signal of which is integrated at 9 and indicated at 10, and may also be compared with a standard voltage. The output is also passed to an automatic control device 11 so that when the pressure falls below 10<SP>-2</SP> Torr switch 4 is automatically changed over to position b to disconnect resistor 2 and capacitor 3 and connect a resistor 12 into the circuit. The circuit no longer operates as an oscillator, the ionization current through tube 5 being indicative of pressure. The voltage drop across resistor 6 is again amplified and passed to stage 8, the output of which is used to control source 1 to limit the ion current e.g. a logarithmic currentpressure relationship may be obtained.
