Title: Improvements in mechanical stokers
IPC: F23K3/16
Filed: 1919-11-05
Abstract: 150,199. Revermann, G. A. W. Nov. 5, 1919. Mechanical stoking. - In a spring-actuated, radial-shovel stoker, means are provided to vary the throw of the shovel by automatically varying the tension of the spring and also to regulate the quantity of fuel supplied to the shovel. The shovel shaft 10 is oscillated and the spring is tensioned by a finger 9 which bears against a double cam 7, 14 and means are provided whereby the contour of the cam 7, 14 is altered to vary the tension of the spring. The driving-pinion 5 revolves in an anti-clockwise direction on the fuelsupply shaft 1 to which is keyed a ratchet-wheel 2. Two pawl levers 3, having a pawl 4 pivoted between them at one end, and a roller 13 mounted between them at the other end, are mounted on the shaft 1 on each side of the ratchet-wheel 2, the pawl 4 engaging with the ratchet-wheel to the extent permitted by a concentric and adjustable sleeve 23, which thus controls the movement of the fuel-supply shaft. The spur-wheel 6, driven by the pinion 5, has a cam 12 mounted upon it which bears against the roller 13 and tends to move the pawl levers 3 in a clockwise direction, the opposite motion being caused by the engagement of the cam 8, also mounted on the spurwheel 6, with the projecting piece 11 mounted on the pawl levers 3, the pawl 4 operating the fuelsupply shaft in the clockwise direction. The double cam 7, 14 is attached to the cam 12, the portion 7 being rigidly secured thereto and the portion 14 being pivoted at 15 and carrying at one side a hook-shaped extension 16. The extension piece 16 bears against a notched cam-piece 17 which is secured to a toothed wheel 18. The wheel 18 is revolved one tooth per revolution of the spurwheel 6 by engagement with a catch 20, which may, however, be disengaged if required, and the cam-piece 17 is therefore placed in different positions relative to the extension piece 16, and thus varies the contour of the operative portion of the cam 7, 14. A pawl 21 prevents retrograde motion of the wheel 18. A spring 17<a> releases the extension-piece 16 from the cam-piece 19 when movement of the wheel 18 occurs.

Title: Treatment of cellulose derivatives
IPC: C08B3/22
Filed: 1932-10-06
Abstract: Cellulose esters and ethers are obtained in a subdivided form by evaporation of solutions containing solvents and non-solvents for the cellulose ester &c., the non-solvent being less volatile than the solvent so that as the latter evaporates the cellulose ester &c. is precipitated by the non-solvent.  By incorporating in the cellulose ester solution, plasticizers and other ingredients either in solution or in suspension, the cellulose ester is precipitated together with these, giving products suitable as moulding-powders.  In the case of cellulose acetate, acetone is a suitable solvent, and water may be used as the non-solvent.  It is of advantage to add non-solvent in quantity sufficient to produce incipient precipitation of the cellulose ester &c., even until the solution assumes a milky appearance.ALSO:Moulding-powders are made by the evaporation of solutions of cellulose ester and ethers containing plasticizers and other suitable ingredients either in solution or suspension, the solution containing non-solvents less volatile than the solvents so that as the latter evaporate, the cellulose ester &c. together with the plasticiser &c. is precipitated.

Title: Improvements in or relating to electrical data storage devices
Inventor: SMITH KENNETH LESLIE
IPC: G06F5/01
Filed: 1958-08-29
Abstract: 881,909. Magnetic core matrix stores. INTERNATIONAL COMPUTERS & TABULATORS Ltd. July 24, 1959 [Aug. 29, 1958], No. 27884/58. Class 106 (1). A magnetic core data-storage matrix comprises, as shown in Fig. 1, four two-dimensional arrays 3, 5, 7 and 9 each having 16 rows and 11 columns, providing 16 storage locations for 10-digit decimal numbers (plus a sign digit), numbers being read out in serial-parallel form by energizing the column lines CL1-CL11 in succession, the binary coded digits appearing successively on lines 11-14, each of which threads all the cores in an array. A waveform generator 39 provides timing signals for reading out, and also for writing back into the matrix for shifting data, and a programme device 57 selects addresses in the matrix in conjunction with a magnetic core address decoder 58 (Fig. 4, not shown) which energizes a selected row line AL1-AL16. To read out the selected row, gate 62 is opened by 57 to set the first stage of a magnetic core shift register in read timing device 59 (Fig. 3, not shown), and the condition is stepped through its 11 stages by pulses on lines 95 and 96 alternately; as each stage is operated it energizes the corresponding column line. The output bits on lines 11-14 are passed through either gates 23, 25, 27 and 29 or gates 24, 26, 28 and 30 depending on whether line 31 is energized or not, so that they pass either through delay flip-flops 34, 44; 35, 45; &c., or through 44, 45 &c. alone. Thus the delay between the reading of a column and the appearance of the data read on lines 49-52 is controlled by programme device 57 over line 31. The data appears on lines 49-52 in complementary form, and is passed through gates 53- 56 to set, where appropriate, " inhibit " cores 142-145, which when reset over line 147 energize inhibit windings in the four arrays to prevent the setting of corresponding cores. If the data is to be re-entered in the same position, gate 70 is enabled over line 74, and 31 is not energized. The read pulse on RT2 for the second column is then transmitted over 69 to set the first stage of write timing device 60 which also comprises a magnetic core shift register, and the write lines WT1-WT11 are energized in turn, commencing after the reading of column 2, and simultaneously with the resetting of 142-145 after entry of the column 1 data. To effect a shift of information from column 1 to column 2 &c., line 31 is energized so that the extra delay introduced by 34 &c., ensures that the column 1 data is entered when WT2 is energized. To shift into the next lower denomination gate 71 is enabled over line 75 so that the write timing device does not start to operate until the fourth line is read by RT4; line 31 is energized to give the longer delay so that the data from column 2 is then read from 142-145. A shift downwards of two denominations is effected by de-energizing line 31, and shift of up to six places downwards can be effected by appropriate combinations of gates 72, 73 and " short " and " long " delays.
