Title: Improvements in and relating to electro-magnetic controlling apparatus for transmitting movement electrically
IPC: G05D3/14
Filed: 1928-05-04
Abstract: 311,091. Brewer, G., (Krupp Akt.-Ges., F.). May 4, 1928. No Patent granted (Sealing fee not paid). Controlling extent of travel; maintaining defined speed.-For the purpose of controlling an electric motor B so as to run synchronously with or repeat the movement of a member A rotated by a handle or other means, a generator A<1> coupled to the member A produces an electromagnetic field, proportional in strength to the speed of turning the handle; the field acts as the exciting field of a generator D which thus supplies stronger current of proportionate strength to the field F of a Ward Leonard generator G feeding the controlled motor B. In addition a hunting-switch M differentially actuated by bevel wheels mechanically coupled to the shafts of A and B closes automatically when either shaft gains on the other, thereby switching in additional field coils M<2> of the generator G in the proper direction to produce compensation. In connection with the generator D, means may be provided for correcting phase displacement as described in Specification 27543/13.
Patent GB-1119136-A (GB)
Title: Method of producing so water and gas with low so content from combustion gas with high so content
IPC: C01B17/54
Filed: 1967-03-21
Abstract: Combination gas, produced by burning sulphur, is cooled and then divided into two streams from one of which SO2 is absorbed in water and from the other a stream of SO2 diluted with air is obtained, the process being carried out under superatmospheric pressure which is maintained by a compressor which supplies a stream of compressed air which is divided into one stream for the combustion and another for the dilution, the cooling of the hot combustion gas being carried out in a first stage in which the gas, in direct contact with cooling water, is saturated with said cooling water and thereby cooled, preferably to about 100 DEG  C., and then further cooled in a second stage in an indirect surface cooler, preferably to about 50 DEG  C. If the second cooling stage is carried out at a higher level than the first the condensate separated from the gas in this second stage can by its own weight be caused to join the circulating cooling water used in the first cooling stage.  The SO2 content of the diluted SO2 gas can be maintained constant by using a meter of said SO2 content to control the quantity of dilution air supplied and the quantity of combustion air can be simultaneously maintained constant by using a meter of said combustion air to control the output of the compressor.

Abstract: 394,123. Tills ; money-delivering apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(GZM Patentverwertungs-Akt.-Ges. ; Glarus, Switzerland.) May 7, 1932, No. 13256. [Class 116.] In a device for receiving and delivering money, of the type comprising a band 13, as shown in the Figure, wound on to or unwound from rollers 2, 4 by racks 9, 11, pawls 60a .. 60d, serving to permit actuation of the deliverydevice only when the required number of notes is available, and a disc 219 moved stepwise in opposite directions by the racks, the disc is provided with a pin 223 adapted to rock a lever 66 upon a shaft 63 on which the pawls are mounted, when the number of notes still available for delivery is less than the maximum number corresponding to any one of the controlling pawls. The roller 2 is driven from the rack 9 by a ratchet-and-pawl arrangement 201, 203 from a disc 207 which is rotated from the rack through gearing 6, 8; a similar arrangement drives the lower roller, abutments 213, 214 serving to disengage the respective pawl when the appropriate rack is fully retracted. When a note is placed on the table 1 and the handle 12 is operated, the band is unwound from the lower roller and the note taken up; simultaneously a pawl 110 on the rack rotates a ratchet 102 and a bevel wheel 222 so that the disc 219 is accordingly rotated through one circumferential tooth 234. When the rack 11 is moved to eject a note, a pin 20 thereon engages an arm 232 with a pivoted finger 235 so that the disc is rotated stepwise in the reverse direction by the pawl 230. In the example described, each pawl 60a .. 60d has a corresponding reciprocating-rod 46 .. 49 serving respectively for the delivery of one, two, three, and four notes. When four or more notes are available, the positions of the pin 223 and the shaft 66 are such that the pawls lie behind projections 61 on the corresponding rods, the motion of which is consequently limited ; under these conditions, when the device is operated for the delivery of a number of notes up to four, the corresponding rod serves to couple a reciprocating shaft 21 with the rack 11 for a period sufficient for the ejection of the required number of notes. As the number of notes falls below four, the pin 223 causes the lifting of successive pawls so that the corresponding rods can no longer be successfully operated. A number of devices of the type described are arranged side-by-side in one machine.

Title: Improvements relating to bleeder turbines
IPC: F01K7/34
Filed: 1924-06-04
Abstract: 217,225. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Johnson, J. F.). June 8, 1923, [Convention date]. Regulating.-In an extraction turbine, the extraction is governed by a valve 16, Fig. 8, and the steam passed to the stages beyond the extraction point is governed bv an interstage valve 14. These valves are coupled together by a rod 27 and the ports of the valve are such that both valves may be fully open together and either wholly shut with the other fully open. They are operated by a relay 31 and hunting gear under the control of a device 35 responsive to the pressure in the extraction pipe arranged to keep the extraction pressure constant and are also under the control of the main speed governor 19 whereby when the turbine speed passes either an upper or lower limit the extraction pipe valve 16 is shut. This prevents extraction when all the steam is required for the turbine and prevents the turbine being run by steam passing back from the extraction pipe when the main valves are being shut. The interstage valve 14 is linked to the rod of a relay piston 31, Fig. 5, and fluid is admitted and exhausted from the cylinder 33 bv means of a piston valve 44 operated by a hunting gear 62, 60, 58; the lever 58 being connected to the relay piston 31 and the pressure responsive device 35 having a steam pipe connection 36 with the extraction pipe. The lever 62 is mounted upon a rod 68, normally stationary but held by a spring 69 so that it can be depressed and thereby the piston 31 caused to move to close the extraction valve. The depression is effected by a lever 65 pivoted at 66 and connected to mechanism 18, Fig. 7, by which the speedgovernor controlled turbine valves 70, 71 are operated. The governor lever 82 is linked to a rocking arm 78 and when the lever is raised by the governor the arm 78 by reason of the spring 84 moves first about the point 77 as a pivot and opens the valve 70. When the valve 70 is fully open, the arm is moved about the point 76 and the valve 71 is opened against the full strength of the spring 84. The ends 95, 96 of the arm 78 slide upon pendant rods 93, 90 pivoted upon a lever 87 and carrying adjustable stops 94, 97. When both valves are closed the end 95 depresses the stop 94 and when both valves are fully open the end 96 raises the stop 97. Both movements impart a counterclockwise movement to the lever 87 and cause the lifting of the end of the lever 65 and thereby the depression of the pivot rod 68, Fig. 5. By these means, when the turbine is overloaded and when it is shut down the extraction valve is closed. Reference has been directed by the Comptroller to Specification 210,084.
