Title: Process and apparatus for crystallizing from solution
IPC: B01D9/00
Filed: 1953-04-28
Abstract: <PICT:0742891/III/1> In crystallizers with internal cooling systems, the cooling system is resiliently mounted and subjected to periodic impulses to detach from the cooling surface crystals forming in the periods between the impulses.  In the apparatus of Fig. 1 a vertical cylinder 2, insulated on the inside with vulcanite and provided with a water jacket 1a to prevent crystal growth on the walls, houses a double pipe coil cooling system 13, 14 supported by brackets 15 from a central tube 16, the whole being supported by a ball race 20 on a rubber mounting 19.  Cooling liquid enters at 17 passes down the tube 16, up the coils 13, 14 and out at 18. The cooling system may be rotated by the motor 21, resulting centrifugal force clearing crystals and any slime from the cooling system.  The upper end of tube 16 carries an anvil 24 which is periodically struck by a hammer 23 which imparts periodic shocks to the cooling system and also sets up a free longitudinal vibration therein.  The cylinder 2 is supplied with crystallizing solution tangentially at 6, a rotary motion being thereby imparted to the solution.  Excess solution is fed in, the excess being taken off by overflow 9, a constant level being thus maintained.  Crystals and mother liquor are continuously or intermittently removed through valve 5.  The apparatus of Fig. 2 is similar to that of Fig. 1 but the cooling system does not rotate, is suspended by five springs and the cooling coils pass through and are rigidly secured to three radial plates which are rigid with the central tube and extend up to a top cap so that the impulses imparted by the hammer are directly transmitted to the cooling coils.  By synchronizing the impulses with the natural period of vibration of the cooling system and springs a large amplitude low frequency oscillation may be maintained in the cooling system as a whole as well as higher frequency damped vibration in the cooling coils set up by each impulse from the hammer.  A constant level of liquid is maintained by a float valve and crystals and mother liquor are continuously removed by a vane valve.  The parts of the cooling system are preferably highly polished and may be chromium plated to assist detachment of crystals therefrom.  The cooling pipes may be of circular or oval section with the major axis vertical.

Abstract: 661,996. Grid resistances. WALSH, Ltd., E. A. and J. Y. April 28, 1950 [May 3, 1949], No. 11753/49. Class 37. A grid resistance is formed from a single length of thin resistance material bent to and fro on itself to form a number of parallel elements, each portion being initially curved longitudinally so that on heating expansion or distortion of all the elements takes place in one direction only, thereby preventing adjacent elements from coming into contact. The resistance is formed of a flat strip of metal A bent on itself a number of times to form a grid comprising a number of parallel elements a. Each element a has a transverse hole near each end to receive a micanite tube B mounted on rods B1, which are connected by bracing bars C. The ends of adjacent elements a are separated by two metal washers b with a micanite washer b<SP>1</SP> between them, the metal washers b carrying a portion of the current across the hole in the strip and so compensating for the loss of crosssection of the element. Each element a is given a predetermined curvature by forming it longer than the distance between the rods B<SP>1</SP> and bending longitudinally, the curvature of each element being in the same lateral direction. The elements may be stiffened longitudinally by forming the edges with beadings either with or without wire reinforcement, or the elements may be corrugated longitudinally.

Abstract: 694,218. Door latches. HOUDAILLE-HERSHEY CORPORATION. May 22, 1951, No. 11919/51. Class 44 A door latch comprises a mounting plate 10 having on the outside a pivotally mounted latch member and on the inside a detent 19 mounted to turn therewith and a three armed lever 31, Fig. 1 having a pawl 30 engaging the detent to secure the latch in the fastening position, an arm 41 for engagement e.g. by an outside pushbutton to release the pawl and an arm 42 engageable by the arm 46, Fig. 5, of a release lever 45 mounted on a right-angle flange 11 and actuated by inside means. The latch member has a striking arm 13, Fig. 7, and a retaining arm, a pin 20 from the latter passing through an arcuate slot 21 in the plate 10 for engagement in an opening in the detent. A double spring 40 surrounding the pivot pins 34, 39 of the detent and pawl urges the latch member in the releasing direction and the pawl to the retaining position. As the door closes the latch member engages a channelled striking plate 23, Fig. 8, the arm 13 striking the face 27 to turn the arm 14 into contact with the face 28 where it is retained by the engagement of the pawl 30 with the shoulder 32 of the detent or, in a partly latched position, with a safety shoulder 29. A latch housing 17 secured to the plate 10 rides over the surface 25. The inside release lever 45 is operated through a link 58 connected to an arm 59. Movement of the lever in an anticlockwise direction causes the arm 46 to bear downwardly on the arm 42 of the pawl. Movement in a clockwise direction places a shoulder 62 under a flange 44 on the pawl arm 42 so that the latch cannot be released from the outside. The lever 45 is retained in the neutral or locking positions by a blade spring 52 fixed to the stud 47 and having a nose 55 for engagement in either of a pair of recesses 56 in the lever 45. The lever 45 may be actuated by the arms 67, 68 of a lever 64 controlled by an outside key lock.

Abstract: 807,508. Automatic steering control systems. SPERRY RAND CORPORATION. April 29, 1955 [June 10, 1954], No. 12502/55. Class 38 (4). In an error-actuated servomotor control system the input signal to the servomotor control system is applied to an electrical network having a plurality of time constants to simulate the servomotor control system and the output of the network is compared with the output of the servomotor control system to detect incorrect operation. The invention is applied to the elevator channel of an aircraft autoomatic pilot in which (a) an A.C. signal derived from a pitch pick-off 17 of a gyro-vertical 10 is applied to an amplifier 11 controlling the excitation of a generator 29 supplying a servomotor 12 to operate the elevators 14; (b) a follow-up signal from a pick-off 26 is fed back to the input of amplifier 11 which also develops and adds a differential component of control (c) a selector switch 47 applies to amplifier 11 a signal from either (i) an instrument landing radio receiver 39 to maintain a predetermined path, (ii) the pick-off 44 of a bellows 40 to maintain a predetermined altitude, or (iii) a manually controlled device 45. For monitoring purposes there is applied to a relay winding 65 the difference between signals from gyro pick-off 17, rectified at 48 and suitably modified by a network 51, and signals from follow-up pick-off 26, rectified at 50 and suitably modified by a network 52. Any difference, resulting from incorrect operation of the automatic pilot, causes relay 65 to operate and disengage the automatic pilot by switching off a motor 31 driving generator 29. To prevent such a difference, resulting from a manoeuvre initiated by the radio receiver, altimeter or manual control, the signal from switch 47 is rectified at 70, suitably modified by a network 68 and applied in the appropriate sense to the circuit of relay 65. In modifications, Figs. 2 and 3 (not shown), a signal derived from a separate rate-of-pitch gyro or from a pitch accelerometer comprising bridgeconnected strain gauges is modified by a suitable resistance-capacity network and replaces the monitoring signal derived from pickoff 17 in Fig. 1. In these modifications a monitoring signal is also derived from generator 29 instead of from pick-off 26, as in Fig. 1. Specifications 629,104 and 663,913, [Group XXXVIII], are referred to.
