Title: Improvements in apparatus for cleaning the tubes of water tube boilers
IPC: F28G3/16
Filed: 1921-10-28
Abstract: 192,457. Handoll, P. G. Oct. 28, 1921. Cleaning, fluid-pressure processes for.-Relates to apparatus for cleaning the tubes of water-tube boilers, of the kind employing jets of pressure fluid projected from a blower tube which is rotated by an operating worm-spindle engaging a worm-wheel on one end of the blower tube, the supply of fluid being controlled by a valve operatively connected with the actuating device of the blower tube. According to the invention, the wormspindle is adapted to have both rotary and axial movement, the latter being utilized to open the valve at the beginning of the blowing operation and close it at the end. In the, form shown, the operating spindle i is formed at one end with a spigot i<2> supported in a bearing in an L-shaped steam-tight casing c secured to the boiler front, and carries a valve d co-operating with a seat in the casing to control the flow of steam to the blower-tube a: The initial rotation of the spindle i by the operating hand-wheel results in its axial movement, the worm-wheel g acting as a nut, thus opening the valve d, until a shoulder i<5>, on the spindle i abuts against the end of a thrust bearing provided for the spindle i. Continued rotation of the spindle rotates the blower tube a through the engagement of the worm h with the worm-wheel g, until a stop g' on the wheel a comes into contact with a stop f-<5> on the casing. The position of this stop f<5> may be varied to control the angle through which the blower tube a operates. The worm-gearing g, h is disposed outside the steam casing c, steamtight glands being provided where their respective shafts pass through the casing. Thrust bearings are also provided on these shafts externally of the casing c. The bearing f<3> on the worm-wheel shaft f, which is connected to the blower-tube a through a sleeve e<1>, takes up the end thrust in the blower-tube caused by the pressure of the cleaning fluid and is adjustable by the nut f<6> to tighten the packing of a steamtight gland e in which the sleeve e<1> rotates. The Provisional Specification describes also an alternative stop device in which the angle of rotation of the blower tube is governed by a fixed pin working in a slot or groove in the worm-wheel. It also states that the steam valve instead of being actuated directly by the wormspindle may be actuated by a cam on the wormwheel operating through a lever or other mechanism.

Abstract: 1469872 Pulse-code-modulation terminals NORTHERN TELECOM Ltd 28 June 1974 [29 June 1973] 28850/74 Heading H3H In a terminal for one channel in a pulse-codemodulation transmission system for transmitting a pulse train of recurrent frames divided into a plurality of channels, the clock pulses required for analogue-to-digital and/or digital-toanalogue conversion at the terminal are derived from the frame and digit synchronization pulses from the incoming digital signals. A counter 32 counts the recovered clock pulses and is reset to zero at the beginning of each frame. If there are more quantizing steps than total number of digits per frame a frequency multiplier could be driven by the recovered clock pulses or two or more coders could be provided operating in succession on a single channel. Analogue-to-digital conversion.-The analogue signal 70 is sampled by capacitor 73 the voltage on which then decays exponentially and is compared at 82 with an exponentially increasing voltage on capacitor 76 of polarity determined by detector 83 which also controls the polarity bit of the digital output signal. The count in counter 32 is transferred to register 86 when the comparator 82 switches over. The polarity bit is added at 87 and the digital output signal is gated out on the channel selected at 33 via AND gate 88 and OR gate 16. Digital-to-analogue conversion.-The incoming digital signal is converted to parallel form at 40 and a capacitor 51 charged to a positive or negative voltage in dependence on the polarity bit. The charge then decays exponentially during the time taken for the output of counter 32 to equal the amplitude bits, held at 43. Switch 57 is then opened and the output of amplifier 50 gated out through audio filter 58.
