Title: Improvements in switching circuits
IPC: G06V10/75
Filed: 1962-04-24
Abstract: 1,009,340. Automatic character reading. GENERAL PRECISION Inc. April 24, 1962 [April 24, 1961], No. 15604/62. Heading G4R. [Also in Divisions G1 and H3] A circuit for selecting, upon interrogation, a single extreme value (greatest or least) from a group of simultaneously applied input voltages each on a separate input lead 101-104 comprises for each input lead a thyristor Q5-Q2 (self-latching transistor switch) the input lead being connected to the base and an output lead 201-204 to the collector, and current control means for supplying a predetermined amount of current to a common terminal to which all the emitters are connected, the current being cut off when an interrogation pulse is applied. The interrogation pulse is applied at terminal 199 to cut off transistor Q1 which normally acts as a current source for the thyristors Q2-Q5, the current passing through resistor R2 to hold the voltage at the emitters of the thyristors Q2-Q5 accurately at a preset voltage. When the transistor Q1 is cut off, this current ceases and current through resistor R4 to terminal 126 pulls the emitters towards the - 10 volt level. In this condition all the thyristors Q2-Q5 are cut off. At the end of the interrogation pulse the transistor Q1 conducts again and the voltage applied to the emitters rises rapidly towards +10 volts. As this voltage becomes more positive than any of the input voltages the corresponding thyristor Q2-Q5 will conduct preventing any further rise in the emitter voltage through current drawn through one of the resistors R7, R10, R13 or R16 so that none of the other thyristors can conduct. The conducting thyristors stays conducting until the next interrogation pulse.

Title: Improvements in the production of compact masses from pulverulent metallic oxides
IPC: C22C32/00
Filed: 1928-05-29
Abstract: 321,394. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 29, 1928. Electrodes.-Porous compact metal oxide masses suitable for electrodes particularly for use with an alkaline electrolyte are prepared by mixing a powdered metal oxide with a heavy metal or metals, at least partly in a finely divided condition, and oxidizing the metal by heating in a non- reducing atmosphere at a temperature below the melting point of the components or their mixture. The operation may be carried on with carbon dioxide or water vapour or with admixtures of these with gases such as carbon monoxide or hydrogen or with oxygen or gases containing oxygen. The treatment may be carried on in an inert atmosphere by using a higher oxide of a metal which becomes reduced to a lower oxide in oxidizing the metallic portion of the mixture. A metalic network such as wire gauze &c. or metal scales may be incorporated in the mass before heating. When the prepared masses are to be used they may be impregnated with salt solutions. Examples describe the preparation of masses comprising iron oxide, Fe3O4, from a mixture of this oxide and metallic iron powder in which, in one case, nickel gauze is embedded; also a mass comprising ferrous oxide made by heating ferric oxide, Fe2O3, with iron powder in a neutral atmosphere. Other metals which may be emploved are copper, chromium, manganese and cadmium.

Title: Improvements in and relating to autographic registers
IPC: B41L5/06
Filed: 1954-05-27
Abstract: 763,508. Memorandum appliances. EGRY, Ltd. May 27, 1954 [June 1, 1953], No. 15763/54. Class 16. [Also in Group XIX] In an autographic register wherein superposed strips of forms are advanced by means of rollers 44, 45 and their movement completed by means of aligning pins 62, disengagement of the rollers is effected by a forward movement of the aligning pins by the strips upon the pins entering the aligning holes of the next set of forms. The extent of feed is controlled by the alignment holes, so that the register will function correctly over a wide range of form lengths. The pins 62 are carried by arms 63 secured to a spindle 61 supported by arms 58, 60 at either end of a transverse shaft 57. The main hand shaft 41 is fitted with a toothed wheel 42, which drives the feed rollers 43, 44 through gearing 49, 50 and 51, a cam 69 engaged by an actuating lever 71 mounted freely on the shaft 57, and a lug 74 normally engaging a stud 77 on a lower extension of arm 60 to lock the alignment pins in position. At the commencement of rotation of the main shaft 41 the feed rollers revolve idly, the lower roller 44 being held down by engagement of a surface 81 of its carrier arm 53 over a stud 80 on the arm 60. Cam 69 immediately rocks the actuating lever 71 counter clockwise and the lever rocks the spindle 61 clockwise against a spring 68, by engagement with an element 64 on the spindle, so that the pins 62 are retracted downwardly .from the holes in the strips. As the rotation of shaft 41 continues, lug 74 frees stud 77 and lever 71 displaces the pins 62 towards the oncoming forms by engagement with a stud 96 on arm 58. At this stage, Fig. 13, the lever 71 and element 64 have separated and the pins 62 are bearing against the underside of the strips ready to intercept the next pair of holes. Moreover the stud 80 has passed off surface 81 of arm 53 so that the arm is rocked counterclockwise by its spring 55 to engage the feed rollers 43, 44 to advance the strips. When the next holes register with and are intercepted by the pins 62, the continuing forward movement of the strips returns the arms 58, 60 until the stud 80 reengages surface 81, whereupon the feed rollers 43, 44 are again separated so that strip feed ceases. As the lug 74 finally re-engages under the stud 77 further slight forward movement is imparted to the pins and strips to bring them into the position of final alignment. The shaft 51 is fitted with stop mechanism to limit movement to one revolution ; a slight backward movement is necessary to release the shaft for each operation.

Title: Improvements in and in Apparatus for the Extraction of Oils and Resins from Hops.
Inventor: WOLFF FREDERICK WILLIAM
IPC: C12C3/08
Filed: 1916-11-09
Abstract: 107,155. Wolff, F. W. Nov. 9, 1916. Resins and resinous compounds. - Relates to the extraction of oils and resins from hops and consists in treating hops at a temperature below 212‹ F. with alcoholic vapour of varying strength. Alternative processes are described. According to the first process the hops after extraction of the hop oils are subjected in a cooled still to high value alcoholic vapour injected from above the hops. This dissolves out the softer resins which separate from the condensate by gravity and are suitably concentrated. The hops are then submerged in warm water and weak alcoholic vapour is blown through them whereby the harder resins are dissolved out and are separated from the resulting liquor and suitably concentrated. According to the second process the hops are subjected in a cold still to high value alcoholic vapour injected from above the hops. This dissolves out both oils and softer resins and the oils may be separated from the condensate by subsequent distillation which may take place in the same still which is suitably warmed and provided with free passage for the vapours through the mass of hops. The harder resins are then extracted as in the first method. A suitable apparatus for carrying out the above processes is shown in the figure. A still a is provided with a jacket b through which suitable heating or cooling media may be circulated by means of an inlet c having valved branches e, d and an outlet f having valved branches g, h. Perforated false bottoms x, q are provided, the false bottom q, supporting the hops, having a central tube y provided with a removable cap y<1>. A perforated inlet pipe u for admitting alcoholic vapour is arranged between the false bottoms x, q and a drain cock w<1> is provided at the bottom of the still. The still has a detachable neck l carrying on it a perforated inlet pipe t for admitting alcoholic vapour and a valved water inlet v and the neck is connected through a valve n to a condenser o. The receiver consists of a tall vessel p provided with a syphon overflow p' for the alcoholic part of the distillate and a tap p<2> for withdrawing the oil which floats on top of the alcoholic solution. A cold water spray z is provided to spray water on the distillate issuing from the condenser and thereby facilitate the separation of the oil by the dilution of the alcoholic solution.
