Title: Machine control system
IPC: H03M1/00
Filed: 1962-08-29
Abstract: 1,008,867. Programmed control of machine tools. WARNER S. SWASEY CO. Aug. 29, 1962 [Sept 5, 1961], No. 33151/62. Heading G3N. In a system for the control of a machine tool erasable electrical memory system for storing information in the form of command to be executed is provided and the memory system is not in accordance with the settings of various control elements of the machine as the machine is operated manually through a sequence of operations to effect a record of the operations which are used to control the machine so as to duplicate the sequence of operations. As shown, the operation of the machine is manually controlled by a console 20 having switches for selecting rate and direction of spindle rotation cross-slide and carriage movement. The crossslide and carriage are moved along the bed by a servo 17 and across the bed by a servo 18, the spindle being rotated by a motor 16. A memory matrix M comprising a plurality of magnetic cores arranged in rows and columns is read by a binary register 65 and the information re-inserted by an erase-read-write signal generator ERW. The row of cores to be read is selected by a command selector S which also routes 'write' signals to re-establish the information in the cores The lead-screws for the cross-slide and carriage each drive a Gray-coded disc 119, the positional information from which is compared in a comparator 146, 146<SP>1</SP> with the output of the register 65. When a series of operations are to be repeated the controls are set to perform each operation and the tool moved accordingly. When the tool is manually stopped at the end of each operation the settings of the various controls are stored in one row of the memory for subsequent repetition. The cross-slide and carriage are also controlled by the output of a tape reader TR and command pulses from a spindle generator 227 which issues pulses at a rate dependent upon spindle speed so that the rates of movement of the cross-slide and carriage are correlated with spindle rotation. The spindle pulses are fed to a divider 226 and then through a binary multiplying circuit 228, controlled by the tape reader TR, to a switching device 230 which fast or slow pulses through a switching block 231, 232 settable to direct the pulses, to either the add or subtract terminals of fast bi-directional counter 220, or slow bi-directional counter 221, controlled by the tape-reader. The outputs of the bi-directional counters control the rotation of the servo-drives 17, 18 to position the cross-slide and carriage to the positions determined by the tapereader. Provision is made Fig. 3 not shown for punching a tape in accordance with the information stored in the memory.

Title: Improvements in or relating to braking equipment control systems for mine hoists andlike winding gear
IPC: B66B1/12
Filed: 1947-12-18
Abstract: 641,115. Winch brakes. RUMBLE, R. V., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 18, 1947, No. 33450. [Class 78 (v)] A control system for a mine hoist brake comprises primary and secondary hydraulic control means controlling the flow of fluid through the exhaust conduit of a brake engine 1a; the primary control means (e.g. valve 9) being operable in response to movement of a part (e.g. piston-rod 1) of said brake engine to permit a predetermined proportion of braking effect to be applied irrespective of wear in the brake operating parts; and the secondary control means (e.g. valve 10) being so arranged as to restrict the rate of further retardation of the hoist to a maximum desired value. Figs. 1, 2. Braking arms 5, 6 are pivoted to brake-operating lover 4 which is pivoted at P and is actuated by piston-rod 1, the latter being connected to brake engine la controlled by cataract 2 and weight 3. The fluid circuit passes through parallel conduits 7, 8 governed respectively by large primary valve 9 and small secondary valve 11, the valves being operated by solenoids 11, 12. In the circuit of solenoid 11 is included limit switch 13 having another 13a which is struck by cam 14 adjustably mounted on reciprocable arm 15 pivoted to lever 4, so as to close the switch 13 and so close valve 9. Cam 14 is so adjusted that this occurs after the piston and therefore lever 4 has applied a predetermined (e.g. 50 per cent) fraction of the total braking. After this point the flow of fluid through cataract 2 and therefore the fall of piston of the brake engine is controlled by secondary valve 10. The electrical circuit of the solenoid thereof includes a deceleration detector (e.g. of the type of Specification 571,700) which controls the fall of brake engine piston until the retardation falls below a preset value. The brakes are therefore applied quickly at first and then slowly afterwards. In order to allow for wear of brake-linings switch 13 is fixed on vertical channel member which is adjustably supported by friction linings 19 in fixed supports 18, and it is struck by extension 21 of arm 15 at the end of each complete brake engine movement so that it moves slowly downwards to compensate for the brake wear. Fig. 3. The inlet fluid to brake engine 24 is controlled by valve 22 and the outlet fluid is controlled by primary valve 9 governed as before from switch 13 and by secondary valves 10 and 26, valve 10 being adjustable and inessential and valve 26 being fixed and essential. The two valves 9 and 10 may, alternatively, be in series instead of in parallel. If desired, a speed-responsive switch may be included in the circuit of solenoid 11 so as to give rapid braking throughout the whole of the cage descent and thus to permit only a creeping speed to the cage. Specifications 508,895, [Group XXXIV], also is referred to.

Title: Improvements in methods and apparatus for preparing charges for internal combustion engines or burners
IPC: F02M17/00
Filed: 1935-12-05
Abstract: 467,089. Spray carburetters; vaporizers. KANE, F. A. Dec. 5, 1935, No. 33780. Convention date, Dec. 12, 1934. [Class 7 (iii)] [Also in Group XI] A method of preparing a fuel-air mixture for use in internal - combustion engines or burners consists in spraying the fuel and separately and independently introducing into the fuel stream an atomizing fluid and combustion air, the fluid and the air being each separately introduced in a plurality of stages between overlapping tubes and the fuel stream progressively expanding after each stage. In spraying fuel from a nozzle 50 into a series of Venturi tubes 32 ... 38, arranged telescopically, atomizing air, which may be heated, enters from an inlet 30 through the gaps 39, 40 between the first Venturis to mix with the fuel while cold combustion air enters between the remaining gaps 41 ... 44 from an inlet 47 separated from the inlet 30 by a partition 45. The number of gaps open to either inlet may be adjustable. As shown, the nozzle comprises a serrated or slotted funnel, but its edge may be plain or it may be formed of the space 65, Fig. 13, between concentric funnels 63, 64, an air passage 68 being provided in the inner funnel. Opposed nozzles may discharge into opposed Venturis set at right-angles to the main Venturis, an air port between the opposed Venturis serving to assist the deflection of the stream into the main Venturis. The edges of one or more of the Venturis may be serrated and the largest one open into a bulbous chamber arranged to create eddies to mix the fuel and air further. Heated air may be drawn from a jacket surrounding the exhaust pipe of an internal-combustion engine. In the.form shown in Fig. 18, air and fuel are drawn through the Venturis by a fan 94 and part of the mixture is trapped by a pipe 97 to be mixed with air in a chamber 101 and burnt in a chamber 103. The hot products pass through apertures 107 in a partition 108 behind the fuel nozzle and form the atomizing fluid, the combustion air entering through a port 105. In another form, a blower 115, Fig. 20, supplies cold combustion air through a conduit 118, and air to be heated through a conduit 117 and tangential ports into a chamber 121, where it mixes with the products of combustion of part of the fuel supplied through a nozzle 125 and air drawn through a space 128 around the nozzle, the fuel and air being burnt in a funnel 124 and then mixed with air drawn through ports 130. Specification 468,885 is referred to.

Abstract: 212,634. White, A. E., (Brewster Goldsmith Corporation). Dec. 12, 1922. Drawings to Specification). Sparking-plugs.-The combustion space within the inner end of a plug, the area of the surfaces which bound it, and the aperture by which it communicates with the cylinder are determined according to the compression ratio of the engine. The combustion space and area are varied approximately in inverse proportion to the compression ratio. For low-compression engines having ratios between 5 to 1 and 3 to 1, volumes are specified of from 1.2.5 to 1.75 c. cm., and areas of from 13 to 36 sq. cm. The area used in practice is the area as determined from the above figures, modified according to the heat capacity, conductivity, &c. of the materials employed. When, for example, the working temperature of the electrode is 1900‹ F. absolute, and that of self-ignition of the fuel is 1135‹ F. absolute, the area as referred to above is increased' in the ratio of 1900 to 1135. The net cross-sectional orifice area is determined from the formula O = Kr<n> where O and r represent the area and compression ratio, and K and n are constants to be determined experimentally by using plugs of differing orifice and engines of differing compression ratio.
