Title: Improvements in and relating to electric discharge indicators
IPC: H02H3/04
Filed: 1923-02-06
Abstract: 193,041. British Thomson-Houston Co., Ltd., (Assignees of Creighton, E. E. F.). Feb. 11, 1922, [Convention date]. Protective arrangements.-A device for indicating or recording electric discharges comprises a number of spark gaps, a detector, and an audible or visual indicator. As shown applied to the detection of transient excess voltages on power transmission lines, a high voltage sphere, gap 3 is mounted on an insulator 13 and connected between the line and earth through resistances 21, 22, coherer 17, and smaller gaps 16, 18, current from a battery 26 passing through the coherer and actuating relays 25, 37, 38 to give audible signals on a gong 44, and a numerical record on a counter 45, also to cperate a signal device 46 at a distant point. The gap 16 is sufficient to prevent small static charges from actuating the coherer but allows a heavy discharge across the sphere gap to function through a series resistance 15, and a condenser 20 prevents coherence with high voltages under the spark voltage of the sphere gap. A high resistance 21 acts as a leak for excess charges on the condenser 20, and forces the discharge from the sphere gap through the coherer. Another high resistance 22, preferably liquid, shunts the insulater 13 and functions to clear any residual excess charge upon it by changes in the line voltage. When coherence takes place a current flows from the battery and actuates the. coherer relay 25, relay 37 breaking the circuit and agitating the coherer. The apparatus is mounted in an earthed metallic case, and the following numerical values for a breakdown voltage between 10000 and 50000 are given, capacity of insulator 13, 0.000075 microfarads, condenser 20, 0.0001 microfarads, resistance 15, 1500 ohms, and resistances 21, 22, 100-250 and 40-70 meghcms respectively. The maximum breakdown voltage may be measured by using a number of recorders with different sphere gap settings. The apparatus with certain omission may be used for recording lightning discharges. The coherer and recording devices described may be dispensed with, and a travolling record sheet passed across one of the small gaps to be punctured by the discharges.

Title: Improvements in water gas generators
IPC: C10J3/00
Filed: 1930-02-03
Abstract: 345,411. Water gas generation. TYRER, D., Norton Hall, The Green, Norton-on-Tees, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Feb. 3, 1930, No. 3567. [Class 55 (i).] In the manufacture of water gas, the blast is supplied in different amounts at different levels to a deep bed of coke through valved tuyeres, so that the maximum air supply is at the point nearest to the discharge outlet of the "blow" gases. The air is preferably supplied in amounts increasing with the depth of the fuel and the " blow " gases are withdrawn at the bottom ; the " run " is effected with an updraught. The air supply from a heat regenerator 7 to the producer 1 is injected through tuyeres 13 having valves 16. The " blow " gases are burnt in a combustion chamber 12 and the products pass to a heat regenerator 8. About 30 per cent of the "run" gases are byepassed through valve 15 to the heat regenerator 7 and the remainder to storage through valve 9. Specification 328,643, [Class 55 (i), Coking &c.], is referred to.

Title: A new or improved apparatus for agitating the contents of bottles or other containers
IPC: B01F9/00
Filed: 1955-02-08
Abstract: 839,621. Batch mixing machines. LISSIMORE, J. P. May 7, 1956 [Feb. 8, 1955], No. 3665/55. Class 86 [Also in Group XXX] Apparatus for agitating the contents of containers 15 comprises a plurality of holders 46 for the containers arranged to progress along an endless path through loading and delivery stations 16, 17, the holders being arranged to rotate about transverse axes as they pass from the loading to the delivery station. The holders 46 are pivotally connected to a conveyer chain 18 which passes round an upper sprocket 33, driven from an electric motor 40, and a lower sprocket 34. Each holder 46 is provided with a star wheel 78 having arms 79 which co-operate with studs 80 on the machine frame for effecting two or three revolutions of the holder during the time in which it conveys the container. The bottles 15 are delivered from a conveyer 14 through a loading aperture 16 by the co-operation of fixed bars 48 with a bottle engaging member 54, the latter being attached to a bell-crank lever 50, pivoted at 51, and urged across the path of the conveyer 14 by a spring 57. Movement of the bottle engaging member 54 is timed to occur in synchronization with the arrival of one of the holders 46 in registration with the loading aperture 16 by means of a cam 60 fixed on a shaft 61 which is driven by chain gearing 62, 64 from a shaft 36 to which the lower sprock 34 is attached. The cam 60 is engaged by a follower 65 carried by a rocker 66 connecter by a rod 67 to the arm 58 of the bell-crank lever 50 so that the loader member is retained positively in its inoperative position except that when the follower 65 is engaged by a flat 70 on the cam 60. A synchronizing means responsive to the arrival of a bottle 15 at the loading station comprises a feeler member 74 pivoted at 71 so that when it is engaged by a bottle 15 it swings in an anti-clockwise direction causing a latch arm carrying a stop member 73 also to move in an anti-clockwise direction out of the path of the end 52 of the bellcrank lever 50. At the delivery station an expulsion member 83 having a guide face 84 is disposed in the path of the holders and this member 83 engages the bottles and displaces them through the delivery aperture 17 on to the conveyer 14.

Following station 13, the documents are fed through a path 3c which overturns the documents as they are fed into an error correction station 17 at which the rear surface of the document is presented for spot printing to a row of electrodes 5a similar to electrodes 5. For each error sensed, a corresponding spot will be printed. From station 17, the documents are conveyed to a printing station 18 comprising 80 injection lasers 19 controlled by a power supply 21. Alternatively, a single laser source may be employed in combination with a deflection system.

Title: Hydrostatic transmission control system

Filed: 1974-01-29
Abstract: 1465743 Hydrostatic transmission control; valves EATON CORP 29 Jan 1974 [7 Feb 1973] 03999/74 Headings F2V and F2W In a hydrostatic transmission for a tracked vehicle wherein a valve spool 74 of a control valve 42 meters pressure liquid from a supply line 104 to a pump displacement control line 90 or 92, a manual control rod 70 acts on the valve spool 74 through weak springs 80, 82 and stronger springs 84, 86 arranged so that initial movement of the rod 70 compresses the weak spring to cause a small increase in control line pressure for a predetermined movement of the rod 70 and, when the weak springs are fully compressed, further movement of the rod 70 compresses the stronger springs to effect a larger increase in control line pressure for an identical movement of the rod 70. Initial leftward movement of the rod 70 acts through a plunger 128 to compress the weak spring 82 and move the valve spool 74 left to a position in which pressure liquid is supplied from the line 104 to the forward drive control pressure line 90. The pressure in the line 90 acts back through a duct 116 on the valve spool 74 to move the latter right and prevent further rise in pressure in the line 90 when the pressure therein equals the spring bias. Further leftward movement of the rod 70 causes corresponding increases in pressure in the line 90 until the plunger 128 abuts a stop 112 to prevent further compression of the weak spring 82. Thereafter further leftward movement of the rod 70 compresses the stronger spring 86 to cause a larger increase in the pressure in the line 90 for a predetermined movement of the rod 70. The valve 74 additionally acts as a reversing valve and rightward movement of the rod 70 meters pressure liquid from the supply line 104 to a reverse control pressure line 92 in a manner as described above. As shown in Fig. 1 a pair of hydrostatic transmissions 14, 16 drive tracks 22, 24 on opposite sides of a vehicle. Each transmission comprises an engine driven variable displacement pump 28, 30 in closed circuit with a variable displacement motor 32, 34. The engine 20 additionally drives a pump 62 which supplies pressure liquid through an anti-stall valve 64 to the speed control and reversing valve 42. The control line pressure from the valve 42 is supplied through steering valves 46, 48 to pump and motor displacement adjusting follow-up servomotors 50, 52, 56, 58.
