Patent GB-680944-A (GB)
Abstract: 680,944. Gyroscopic apparatus. SPERRY CORPORATION. June 23, 1950 [June 28, 1949], No. 15729/50. Class 97 (iii). [Also in Group XXXV] In gyroscopic apparatus having means responsive to angular displacement of the rotorbearing frame relative to a control member for controlling torqueapplying devices to apply precessional torques to the rotor-bearing frame to maintain a predetermined angular relationship between the frame and control member means are provided for reducing the effect of the torqueapplying device during a predetermined portion of the starting-up period of the apparatus when the rotor is accelerating up to its normal rotating speed. As shown in a directional gyro provided with a levelling device for maintaining the rotor axis perpendicular to a vertical ring supporting the rotor bearing frame, the rotor 15, Fig. 1, is rotated in bearing frame 14, Fig. 1, by an electric induction motor 17, 18 which draws a decreasing amount of current as the rotor accelerates from standstill condition. A D.C. relay 40, Fig. 2, the energizing winding 46 of which is in series with the power supply to the stator 17 of the rotor motor, on operation opens the contact 41 to connect the resistance 44 effectively in circuit with the winding 36 of the torque induction motor 20 for rotating the gimbal or vertical ring 13, Fig. 1. The other winding 26 of motor 20 is fed with current over a selector switch 21 including a commutator segment 23 fixed to the trunnion of rotorbearing frame 14 and two brushes 24, 25 fixed to vertical ring 13 which carries the horizontal trunnions of the frame 14 so that the switch 21 only conducts current therethrough when there is relative tilt between the frame 14 and the ring 13 from a normal angular relationship. On operation of the relay 40 the current fed to the winding 36, Fig. 2, of motor 20 is reduced with consequent reduction of the torque which can be exerted by the motor 20. The relay 40 is, by means of spring 45, adjusted to operate at a predetermined value of current so that on attaining a predetermined speed of the rotor, the relay will be de-energized and the torque motor 20 rendered effective. In an alternative circuit arrangement, an A.C. relay is employed with its winding connected in series with the current fed to the stator of the rotor motor and is adapted on operation to open the circuit of winding 36 and the selector switch comprises a pair of conducting segments fixed to the trunnion of frame 14 and a co-operating pair of brushes fixed to the ring 13. Damping of the starting rotation of the instrument is obtained by a hollow circular tube 49, Fig. 1, filled with a damping fluid and fixedly mounted to and concentric with the trunnions of ring 13. Specification 623,356 is referred to.
Patent GB-684539-A (GB)
Abstract: 684,539. Cash registers. NATIONAL CASH REGISTER CO. April 2, 1951 [April 5, 1950], No. 7588/51. Class 106 (i). Key-operated locking mechanism for the release shaft of a cash-register cannot be moved to locking position except following a totaltaking operation, and is then moved to locking position automatically. This ensures the machine is locked after each multiple-item transaction and prevents the operator withdrawing his key and locking the machine without first clearing the multiple-item totalizer. The invention is applied to the machines described in Specifications 614,346 and 614,347. Depression of the motor bar 20 frees a spring- loaded lever 26 which rocks the release-shaft 35 to initiate a machine cycle, after which the lever 26 and shaft 35 are restored. A latch 53 pivoted at 54 has an ear 56 normally overlying an arm 34 on the release shaft 35 and prevents release movement, but inward movement of a slidable lock barrel 38 by an inserted key 39, through a lever 49 and link 52, rocks the latch clear of the arm (as shown) to permit the machine to be operated. A locking arm 71 pivoted at 68 engages the ear 56 of the latch to hold it clear whilst the machine is set for adding so that the lock barrel 38 is obstructed against return movement and removal of the key. Movement of the machine setting lever 64, clockwise to the total-taking position, for transferring the items to a group totalizer, displaces a slide 67 into the path of a pin 75 on the release arm 34 so that, when the release shaft is restored at the completion of total-taking, the slide 67 is rocked clockwise and, by means of a pin-and-slot connection, rocks the locking arm 71 clear of the latch 53. The lock barrel can now move outwardly to lock the machine and this is done automatically by the spring 73 of the latch 53. The locking action of the arm 71 is not positive but is sufficient to warn the operator, when he tries to remove the key, that he has not completed the transaction; the key 39 can be forcibly withdrawn if required and a spring 55 and pin-and-slot connection between the lock lever 49 and link 52 yield if the mechanism jams. When the proprietor clears the machine it is unnecessary for him to use an assistants' key 39. The link 52 is actuated to unlock the release shaft by means of a cam 84 and connected levers 88 and 90, the cam being shaped to rock the levers when the proprietor's locked control slide is set in certain positions.

Title: Process and apparatus for removing particles from gas streams
IPC: B03C3/16
Filed: 1979-04-09
Abstract: The apparatus includes a grounded fiber bed 12 of 50 to 1000 mlcron average diameter fibers packed to a bed voidage of from 90% to 98%, an electrostatic field means 8, 10 upstream of the fiber bed to place an electrical charge on the particles, and irrigation means 14 for the fiber bed and optionally for the grounded electrodes 10 of the electrostatic field means as well, to flush collected particles from the fiber bed and optionally from the grounded electrodes. The process is suitable for separation of any particles but is particularly advantageous for separation of insoluble solid particles from gas streams at high bed velocities of from 1.8 to 4.6 or more meters per second. In the process, particles are charged in the electrostatic field means and the charged particles are collected in the fiber bed where the electrical charge is dissipated through the irrigating liquid/particles mixture so that no significant space charge effect is allowed to develop in the fibers of the fiber bed and re-entrainment of particles is avoided. The discharge electrodes 8 are rods having points projecting alternately from each side, parallel to the plates 10. <IMAGE>
