Title: Improvements in or relating to gas liquor treatment and apparatus
IPC: C10C1/08
Filed: 1936-02-07
Abstract: <PICT:0463217/III/1> A process for the distillation of ammoniacal liquor comprises primary distillation in a still 2, with quantities of steam sufficient to remove all acidic gases but insufficient to remove substantial amounts of the tar acids in the liquor, the latter being subsequently subjected to a secondary distillation in a still 22 to remove residual ammonia, and a controllable proportion of the vapours from the secondary distillation are passed into the still 2. A main 26 is provided to carry away the vapours from both stills.  A valve 25 controls the amount of vapour passing from still 22 direct to themain 26, the remainder passing through connection 3 to still 2. Residual liquor from still 2 may be passed through a heater 29 to a tower 9 where phenols are removed as described in Specification 299,837, [Class 32].  In this process inert gases are circulated through the falling liquid in the tower by a pump 14 and these gases are scrubbed with an alkaline solution to remove the phenols carried off by them in a separate section 15 of the tower.  The liquor from tower 9 passes through connection 11 to a section 12 where it is treated with lime to decompose the fixed ammonia compounds.  The freed ammonia is then distilled off in section 22.

Title: An electrical circuit for the detection and amplification of electromagnetic radiation
Inventor: MASH DEREK HUBERT
IPC: G01J1/42
Filed: 1966-01-28
Abstract: <FORM:1111734/C4-C5/1> A photovaractor (i.e. a PN junction device the junction resistance of which varies inversely with illumination and the junction capacitance of which varies inversely with the voltage across the junction) is connected in series with a parallel resistor/capacitor combination, sources of direct and alternating voltages and a load.  The direct source 14 and the resistor 15 act as a constant-current source so that when the device receives illumination and its junction resistance 11 falls, the voltage across the junction falls.  The resulting increase in junction capacity 10 reduces the A.C. reactance of the whole circuit and the increased A.C. flowing energizes a load 12.  An image intensifier may comprise the varactor junction 18, a layer 19 acting both as resistor 15 and capacitor 16, and a ZnS electroluminescent layer 20 as the load 12 all sandwiched between electrodes 21.  The resistive layer 19 may be omitted if the electroluminescent layer has the required electrical properties to take its place.

Title: Improvements in and relating to coin-freed mechanism
IPC: G07F5/04
Filed: 1940-03-05
Abstract: 538,663. Delivery of articles. GARRETT & CO., Ltd., C., and WEST, L. March 5, 1940, No. 4065. [Class 27] In coin-freed apparatus in which a plurality of coins of more than one denomination have to be inserted, one or more of the first coins put in forms a track over which a subsequent coin or coins can pass, and means are provided for returning the coins if insufficient or abnormal coins are inserted, or if they are put in in the wrong order. The drawings show apparatus for vending articles priced at one shilling and twopence, the two pennies being inserted first through a slot 11 and falling into a vertical position in a pocket 20. This pocket forms the lower part of a compartment formed by two walls 18, 19 of which the wall 19 is fixed and the wall 18 hinged thereto at the top with spring closure. The shilling rides over the top edges of the pennies, runs over a slotted platform 23, and reaches an inclined face 25 on a lever 26 pivoted at 27. It tips the lever and falls into a shoot 13 where it releases a catch at the bottom to permit an article-holding drawer to be withdrawn. If the shilling be too thin it will drop through the slot 23a and discharge down a shoot 24, and the two pennies may subsequently be recovered by pulling out the discharge drawer slightly, when an incline thereon will raise a rod 15 sufficiently to open the compartment wall 18 and allow the coins to fall in a crook 28 of the lever 26 and thence drop into the shoot 24. A good shilling will, however, tip up the crook 28 beyond a detent 29, and when the drawer is opened to its full extent the rod 15 will swing out the wall 18 to allow the pennies to fall into a container 30. An arm 35, a pusher plate 34, and an extension 37 effect positive discharge of the coins. A shilling inserted after one penny will fall into the pocket 20 and over a lug 22 to an opening 40 and into the return shoot 24, and the penny may be recovered by pulling out the drawer the short distance possible, the retaining lug 22 allowing the coin to slip past it into the shoot 24. A magnet 41 arrests ferrous coins, and non-milled discs reaching the end of the compartment jam themselves under the inclined base of a sliding and pivoted catch. In a modification the last track coin falls on a stop the height of which may be adjustable, and the width of the pocket 20 may be variable in order to accommodate a selected number of coins. The operative coin is also made to remove retaining means in the pocket 20 and allow the ejection of coins therefrom to take place, and may cause the drawer to open automatically.
