Title: Improvements in and relating to discharge relay and amplifying circuits or arrangements for amplifying or recording wireless signals or for other purposes

Abstract: 353,438. Amplifying circuits. MACKENZIE, W. B., SMITH, H., and HILL, E. G., Signal School, Royal Naval Barracks, Portsmouth. April 22, 1930, No. 12488. [Class 40 (v).] In order to record the exact duration of a received signal, the output voltage from a thermionic amplifier V is fed to the middle electrode of a glow discharge device. The high-tension supply to the latter is interrupted at a frequency higher than that of the signal duration by a motor-driven switch P. The discharge current, produced by the received signal, across the electrodes A, B operates an electromagnetic relay M, which is time-delayed so as not to respond to the interruption-frequency of the switch P. The output from the relay M is used to operate an alarm buzzer, a lamp circuit, a loudspeaker, or other recording instrument. The arrangement is suitable for giving high amplification of any direct or rectified current.

Abstract: 1355904 Cathode-ray tube displays INTERNATIONAL BUSINESS MACHINES CORP 17 March 1972 [5 May 1971] 12510/72 Heading H4T In a cathode-ray tube display system in which a "sheet" of graphic information of larger area than that of the tube screen (or of a selected "window" thereon) is to be displayed the display is produced by effecting a "continuous pass" of the "sheet" across the screen or "window" area. Fig. 1, shows an example of this in which, during the "pass", the area 14 on the "sheet" 10 is displayed in the "window" area 16 of a programme controlled display C.R.T. 12. The display is produced by dividing the "sheet" into an orthogonal grid of square cells of a selected area each cell being stored in means which holds its X, Y co-ordinates and the relevant display orders (i.e. for beam control). A window size is then chosen 35 (Fig. 3A), e.g. of 6 x 4 cells, and an "origin cell", i.e. a cell located in the approximate centre of the window, such as cell 36, is specified. The X, Y coordinates of this cell (i.e. of the lower left-hand corner) on the "sheet", which do not vary, are stored in a display list and the X L , Y L  coordinates of the window on the sheet, the Xw, Yw quantities specifying the size of the window, the quantities X, Y specifying the "off-set" of the window relative to the total screen area 37 and the quantity B specifying the relationship of cells in primary storage (which may be fed from secondary storage containing all of the "sheet" information) but not visible are stored in special registers from which the location of the cell on the screen co-ordinates Xd, Yd are computed. To produce the actual display the stored cell co-ordinates are "scanned" in spiral fashion commencing with the origin cell as shown in Fig. 8 and in the case of graphic information, the display orders are employed to control the main deflection and intensity of the C.R.T. beam as shown in the general system of Fig. 2, the "pass" of the sheet information being effected by suitably incrementing or decrementing the registers holding the origin cell co-ordinates. When alpha -numeric information is to be displayed "stroke" operation controlled by a stroke register 20 and a character stroke deflection circuit 22 becomes operative. Interaction between the system and its user may be effected by means of a lightpen 26. A detailed description of the organization and operation of the system is given.

Title: Improved process and apparatus for the production of water-gas, or gaseous mixtures containing water-gas, poor in carbon monoxide
IPC: C10K3/00
Filed: 1931-04-28
Abstract: In the production of water gas rich in hydrogen by the reaction of the gas in the presence of steam and burnt lime, the sensible heat produced during a part of the gas-generating process is stored and utilized for the reaction and also for the regeneration of the lime. The lime k in a vessel c is heated by the blast gases from a generator a secondary air being added if desired at e<3>.  The "blow" is followed by an up or down "run," the water gas flowing through a heat storage chamber b before contact with the hot lime in vessel c. The gas poor in monoxide passes to a scrubber d and then to storage. Extra steam may be passed into chambers b, c through valves 7, 8. The <PICT:0372089/III/1> reacting mass k is regenerated in the following blast run.  In a modification, the chamber b together with a steam boiler is constructed integrally with the generator.  In a further modification, the plant is adapted to the continuous production of water gas by using two reaction vessels c, the transformation of the monoxide occurring in one vessel whilst the other is being regenerated.  Oxides, hydroxides, or carbonates of alkaline metals, alkaline-earth metals or heavy metals such as iron, chromium, nickel, cobalt, or zinc and also Ankerite may be added to the lime.  Specifications 236,579 and 309,048, [both in Class 55 (i), Coking &c.], are referred to.
