Title: Improvements relating to the Treatment of Solutions to Precipitate Matter contained therein.
Inventor: LILLIE SAMUEL MORRIS
Filed: 1900-10-09
Granted: 1900-12-31
Abstract: 17,924. Lillie, S. M. Oct. 9. Purifying saccharine liquids and syrups.-Relates to the treatment of sugar juices, and other solutions, for the purpose of precipitating matters contained therein. The solutions or juices, which may be treated with lime, sulphurous acid, carbonic acid, phosphoric acid, or other reagent, are fed from a reservoir 1 into a heater 3, supplied with low-pressure steam from a pipe 4. A perforated pipe 5, in the upper part of the heater, breaks up the liquid as it leaves the feed-pipe 2. A suitable float valve 6 regulates the feed. Gases or vapours may be conducted by means of a pipe 7 to any apparatus in which they may be used for heating purposes. The partially-heated solution may be drawn from the heater 3 by means of a pump 9, and delivered along a pipe 10 into a heater 11, provided with a perforated plate 12 and supplied with high-pressure steam from a pipe 13. Gases and vapours may be conducted by means of a pipe 14 into the heater 3. The steam pipe 17 of the pump 9 is provided with a valve 15, which is controlled by means of a float 16 in the heater 3 ; a bye-pass pipe 18 and valves 19, 20, 21 may also be fitted to the pipe 17, to allow the pump to be operated independently of the action of the float 16. From the heater 11, the solution flows into a closed storage tank 22, whence it passes into a closed cooling-tank 23. The flow from the tank 22 to the tank 23 is controlled by means of a valve fitted within a casing 26 and actuated by means of a float 27 connected to a sleeve, which is carried by a spindle 35. Adjacent to the sleeve is a second sleeve, which is fitted upon the shaft 35, and carries an arm engaging with an aperture in the valve rod. The shaft 35 is movable longitudinally, and carries a key which engages with a keyway in the valve-rod sleeve, and with any desired keyway of a series formed in the float sleeve ; by this means the solution in the tank 22 may be maintained at any suitable level. The steam generated in the cooling-tank may be led by a pipe 47 into the heater 3, or along a pipe 49 into an evaporator 50. The liquid is discharged from the tank 23 into a suitable separating-apparatus, such as a filter 52, and the separated solution may be fed along a pipe 53 into the evaporator 50. The tanks 22, 23 may be used in conjunction with surface heaters instead of the jet or spray heaters shown. The apparatus may be used for treating sea-water, or saline solutions, as a preliminary to evaporation.

Title: Improvements in or relating to the Interlocking of Railway Points and Signals by Means of Keys.
Inventor: HEPPER HARRY ALBERT LAWLESS
Filed: 1901-05-03
Granted: 1902-04-24
Abstract: 9219. Hepper, H. A. L. May 3. Interlocking.-Relates to the interlocking of railway points and signals by means of keys, and more particularly to apparatus for controlling the release of the keys, the apparatus being adapted to prevent the transmission of a current from one instrument to release a key at a distant instrument, unless the key of the first-mentioned instrument has been placed in its lock, and has been turned into a position in which it is locked against removal until released from the distant instrument. Figs. 2 and 3 show respectively back and front views of the apparatus with the casings removed. The pivoted locking-plate d operated by the key is provided with a pin h engaging in the slot g in the pivoted blocking-plate f, which is actuated by the spring i to lock the bolt in both extreme positions of the latter. The bolt is pivoted at e, and is formed with a slot k<2>, k<3> for the releasing-plunger. In the normal position, as shown, the boss k on the plunger cannot pass through the narrower part k<2> of the slot, and the plunger therefore cannot be operated to release the key from the distant instrument. When the key is inserted and turned through its full movement, the slot k<3> is brought into position to permit the operation of the plunger, and the bolt is then locked by the pawl m<2>, Fig. 3, engaging a detent on the quadrant arm m' fixed to the spindle m of the bolt, so that the key cannot be withdrawn again until it is released from the distant station. The release is effected by the electromagnet n' disengaging the pawl m<2>. When the key is not in the lock, a break in the contact r is open, and the instrument is disconnected from line, but when the key is inserted and turned, this break is closed by the contact u<2> on the arm m<1>, so connecting the line-wire through the terminal p, contact o<2> on the bar o, and contacts r, u' to the releasing- electromagnet n<1>, bell, and current indicator s. These indicators show when the releasing-current is passing, and also indicate, by their return to normal position, the withdrawal of the key released. The plunger k, when pressed, actuates the bar o so that the contact-maker o<2> connects the battery contact q to line through the contactp, to effect the release of the key at the distant station, the current passing through the indicator s, battery, and contacts q, o<2>, p of the home instrument to line, and thence through the contacts p, o<2>, r, u<2>, electromagnet n<1>, bell, and indicator of the distant instrument. When several keys have to be freed at each station, a separate pair of instruments is provided for each key, but only one bell, and, if a bell code is used to intimate which key is to be released, only one indicator need be employed at each station.
