Abstract: 206,834. Henneman, K. F., and Kerkhoven, P. Nov. 5, 1923. Fluid actuation.-Relates to electric water heaters in which the turning on of a cock to draw water automatically, closes a switch in the heating circuit. The actuating means for the switch 26 include a cylinder 35, a piston 38 with perforations 40 through it, and a piston-rod 48 connected by links with the rotatable shaft 16 of the switch. When the cock is closed, the piston is kept in the position shown by a weight 44 acting through links 45, 46. Opening of the cock allows water to leave the cylinder by a pipe 37, and water entering by a pipe 36 presses the piston 38 to the left. This causes (a) the opening of a bypass 51 whereby an adjustable amount of water passes through to the heater, (b) the engagement of a collar 47 on a piston rod 48 whereby the per. forations 40 are closed and (c) the movement to the left of the piston rod 48 and consequent closure of the switch 26. In a modification there are several cocks. and the inlet to the by-pass 51 is elongated so that successive opening of the cocks moves the piston to the left in steps and causes the successive energization of several heating coils.

Title: Improvements in or relating to liquid meters
IPC: G01F3/38
Filed: 1960-08-12
Abstract: 881,368. Meters for crude oil. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 12, 1960 [Aug. 14, 1959], No. 28000/60. Class 69 (1). An apparatus comprises a measuring vessel having a top, gas outlet 2, a bottom, liquid outlet 3 and a side inlet 4 for a gas-liquid mixture, a level regulator 10 which operates by pressure the servomotor 8 of a valve 7 which is opened when liquid in the vessel reaches a maximum level 13 and closed when it reaches a minimum 14, and a gas-pressure regulator 18 which operates by pressure the servomotor 16 of a valve 15 in the top conduit to maintain gas pressure in the vessel at the same constant level both when the liquid level is rising and when it is falling. The regulator 10 is additionally connected to the servomotor 6 of the gas-outlet valve 5 and the regulator 18 to the servomotor 20 of the liquid outlet valve 19. So as respectively to set these valves in the opposite conditions of opening or closing to those in which they simultaneously set the valves 7 and 15. The regulators may operate the valves by either pneumatic, hydraulic or electrical means and the valves need not all be of the same type. In an alternative arrangement in Fig. 2 there is only one valve 29 or 30, each with its servomotor 27 or 28, in each of the outlets 2 and 3. The level regulator 21 is operated by a float 22 instead of by differential pressure as is 11 of Fig. 1, and controls a four-way cock 23 which can connect either valve 29 or 30 alternately to the gas-pressure regulator 18, whereby it is opened, or to the atmosphere at 24, whereby it is closed. Clocks 31 and 32 which total the amount of time the respective valves are open are started and stopped by the same means. The cycle in the latter embodiment is as follows: The liquid level rises to 13 causing the regulator 21 to close the valve 29 and stop the clock 31 by connecting them with the atmosphere at 24. Simultaneously the gas regulator starts the clock 32 and opens the valve 30 to discharge the liquid from the vessel at such a rate that the gas pressure remains constant whilst the level falls. When the level 13 is reached the regulator 21 reverses the connections at the cock 23 and the regulator 18 maintains the gas pressure at the same constant value whilst the vessel refills to the level 14 timed by the clock 31. The records from the clocks enable the delivered quantities and rate of flow of gas and liquid to be determined.

Title: Improvements in planetary ball mills
IPC: H05B41/19
Filed: 1931-10-09
Abstract: 386,730. Roller-and-ring mills. INTERNATIONAL COMBUSTION, Ltd., Aldwych House, Aldwych, London.-(Assignees of Crites, J. ; 200, Madison Avenue, New-York, U.S.A.) Oct. 9, 1931, No. 28113. Convention date, Oct. 9, 1930. [Class 59.] In a planetary ball mill the inner grinding ring or rings are forced by means of springs into contact with the grinding balls to allow variations of distance between the inner and outer rings, such springs taking no part in the drive of the inner ring or rings which are driven positively from the vertical driving shaft and which are so connected with the shaft as to be slidable thereon and capable - of a limited lateral or oscillating movement. As shown in Fig. 2, a ring of balls 53, which do not completely fill the track 50 are driven by rings 55, 56 loosely mounted on a hub 63 keyed to a shaft 32 driven by bevel wheels 42, 43. The rings 55, 56 are perforated and are urged toward one another by springs 59 on bolts 57. The underside of the ring 56 is provided with scoops 68 to assist the ploughs 72 in throwing the unpulverized material back to the balls through the perforations 67, the peripheral edge of the ring 56 being bevelled at 69 to deflect some of the material directly to the balls. The material to be pulverized is fed to the balls through a rotary feeder 5 and the material which is not ground by the balls is thrown back by the plough. An air current, supplied to a spiral casing 21 surrounding the balls, carries off the ground material through an outlet 8. The bevel wheels 42, 43 are housed in an oiltight casing 37 and the spider of the plough is provided with a labyrinth packing 78 which is drained by a pipe 82. The shaft 32 rests on a thrust bearing 45 and the upper end is supported in a bearing 30 attached to a transverse beam 28. In a modification, Fig. 9, the driving ring 85 is pressed down by springs 99 abutting an adjustable spring cap 100 attached to a bolt 102, the head 104 of which, Fig. 12, is provided with a thrust bearing 105 in a longitudinally sliding cage 106 attached to a screw 109 and movable by a worm 115 and worm wheel 110. The driving shaft 103 is hollow, to accommodate the bolt 102, and is driven by bevel gear. A sleeve 95 is fixed to the shaft and is loosely connected with the ring 85, the lower part of the sleeve being flared to protect the bearing 91 of the shaft, surplus oil from this bearing draining back to the sump through a channel 93.

Title: Splicing apparatus
IPC: H04B3/46
Filed: 1976-07-07
Abstract: 1503428 Line transmission systems H J MARSTON 7 July 1976 28344/76 Heading H4R In an arrangement for switching in a by-pass 24 between two points on a transmission line 20, 21, two units 10, 14 are coupled to the transmission line and should a test connection between the two units cease on switchover to the by-pass, an automatic guard circuit is operative to override the switchover. The master unit 10 and remote unit 14 are each coupled by A and B cords 54, 156 and 52, 154 to the tip and ring conductors 20R, 20T of the transmission line section 21 to be by-passed at points on either side of the positions 28, 30 at which the line 20 is to be cut. By setting selector switches 40, 148, a verify A check is then performed by transmitting a 1400 Hz signal from the master unit over A cord 54, the line section 21 and A cord 156 to two tone detectors, in the remote unit, which are coupled respectively to the wires T and R, the wire 26 acting as a return signal bus. Tip and Ring indicators 150, 152 illuminate on receipt of the tone. A similar verify B check is performed to check the path via the B cords 52, 154 and line section 21, between the two units. Switches 40, 148 are switched to a "cut" position to couple A cord 52 to B cord 54 within the master unit and to couple A cord 156 to B cord 154 at the remote unit. The line is cut at 28, 30. A transfer switch 42 at the master unit 10 is then operated to energize a guard relay (112, Fig. 2, not shown) which completes a direct current path over wire 27 extending between the two units and fed by a constant current source to compensate for line length variations. Current flow in this wire is detected in each unit using LED's and photodetectors to cause the B cord of each unit to be disconnected from the A cord and to be connected to the by-pass line 24. During the changeover the verify tone is transmitted between the two units and if it should cease on changeover an SCR conducts to short out relay 112 thereby returning the path to the A cords and line section 21. Assuming a successful switchover, a capacitor is charged to operate a second SCR after about 50 ms. to disable the guard arrangement. The line section 21 can then be replaced by a new section 22, which can be checked prior to changeover from the bypass using a test similar to the verify A and B tests. The master unit is also supplied with a meter 46 for monitoring the level of the carrier of an active transmission channel using the line 20, 21. There is also provided means for coupling an external tone generator to the transmission line, with a level control potentiometer being provided therefor.
