Title: Improvements in Maximum Indicators for Electricity, Speed and other Registering Apparatus.
IPC: G01R11/60
Filed: 1916-03-24
Abstract: 104,924. Chamberlain & Hookham, and James, S. March 24, 1916. Periodic-counter speed indicators.-Relates to apparatus of this type which, at regular clockcontrolled intervals, effects the advance, by the mechanism to which the indicator is applied, of an intermediate member from zero; the position reached at the end of the interval is communicated by a one-way driving connexion to a non-return indicating element, which is only brought back to zero when a restoring device is operated manually. The apparatus thus indicates the maximum speed attained since the previous resetting. A wheel 9, Fig. III., mutilated as shown to prevent overwinding, is driven from the meter or other shaft (not shown) through gearing 1, 4, 5, 6 and a worm 8, on a shaft one end of which is supported at 20, Fig. V, by a lever pivoted at 22. The lever is held down upon an adjustable stop 37 by a spring 25 connected to the core of a solenoid 27, which is periodically short-circuited by a clock switch to disengage the worm 8 and allow the wheel 9 to return to its starting position under the influence of a spring 11. A pin 12 on the wheel drives a pin 13 on a ratchet-wheel 14, which is connected to the pointer and is detained by a click 17. To reset the pointer, a three-armed lever 30 is moved by means of a push-rod 31 to lift the lever and release the click 17, whereupon the wheel 14 is returned to its zero position by a spring. To prevent unauthorized resetting, a push-button mounted in the casing of the meter opposite the push-rod 31 is perforated to receive a sealing- wire. The device is applicable to gas and electric meters as a maximum-demand indicator Specification 11541/07 is referred to,

Title: Improvements relating to distillation apparatus
IPC: B01D3/24
Filed: 1954-02-15
Abstract: <PICT:0755548/III/1> <PICT:0755548/III/2> A fractionating column is provided, on opposite sides therein, with plates such as that shown at A (Fig. 1) which extends only partially across the X-section of the column and ends in a sill a over which the liquid-reflux flows; a vapour-guide screen C is disposed below the plate and forms with the plate and the column a passage-way which causes the rising vapour as it approaches the plate to increase in velocity and assume an increased velocity in a substantially horizontal direction so that it pulverizes the sheet of liquid flowing from the sill and carries the liquid particles along with it.  The vapour with the entrained liquid particles collides with wall D whereby separation of the liquid from the vapour occurs.  The vapour then rises to the next plate A1 being withheld from further contact with liquid on plate A by a screen C1 which has one end d dipping in liquid in a trough b on plate A. Screen C1 also acts as vapour-guide screen for plate A1. The liquid separatd at wall D flows down into the trough of the plate below plate A.  Some of the entrained liquid is projected against the lower surface screen C1, and falls into the space ac, where it is taken up again by the vapour current, or is returned to the plate A.  In the embodiment shown in Fig. 4, the inner part of each plate is curved so as to give the liquid droplets a component of acceleration in the direction of gravity; and each screen is joined between the immersed end d and the lower edge c so that the whole of the liquid is passed through the vapour current.
