Title: Improvements in lathes or like machine tools
IPC: B23B5/00
Filed: 1938-09-12
Abstract: 517,753. Lathes. NICHOLSON, H. G. Sept. 12, 1938, No. 26564. [Class 83 (iii)] Lathes particularly intended for turning projectiles have a headstock a which extends to the base provided with a gap piece v which in conjunction with a removable tie j enables endless belts to be placed in position without dismounting the headstock spindle. The side walls a<1>, a<2>, are also tied at s by a preferably integral brace and the tie j is further connected at k to an arm r. The bar k may serve as a steady when a turret is employed in place of the tailstock which is mounted on a cross slide to facilitate insertion and removal of work. The movements are preferably hydraulically controlled. The bed h is bolted at x to the side of the headstock which carries a larger diameter pulley than would be possible if the headstock be bolted above the bed. In a modification the bar k is replaced by a member having inverted guides for the saddle and tailstock.

Title: Method and device for producing a combustible air-liquid fuel mixture
IPC: F23N1/02
Filed: 1975-06-25
Abstract: 1517001 Spray carburetters DRESSER INVESTMENTS NV 25 June 1975 [3 July 1974] 26998/75 Heading F1H The supply of fuel to an induction passage at or upstream of a variable area throat zone 22 in which for most conditions of use the fluid-flow is sonic is in direct proportion to the throat zone area for any particular pressure at a location upstream of the throat zone where the cross-sectional area ratio between the throat zone and the transverse plane at the location is constant and is dependent on the pressure at the location. In the embodiment shown a needle 36 or a rod (40, 44), Figs. 8 to 11 (not shown), with a tapered slot (42) or slots (46) is moved with a member 18 defining the induction passage to control a fuel discharge opening 34 at a location of constant cross-sectional area ratio, fuel being supplied to the opening at atmospheric pressure. The facing walls of the members 16 and 18 are parallel at least from the zone 22 to upstream of the opening 34. The pressure at opening 34 may be about 1 in Hg. The fuel-flow may be controlled by a valve (60), Fig. 12 (not shown), upstream of the fuel outlet the valve being linked for movement with the member 18 and the pressure at the location upstream controlling a pressure regulator (74) in the pumped fuel supply. In a carburetter with two induction passages, Figs. 13 to 16 (not shown), the valve controls fuel-flow to a plurality of ports (132) opening upstream of the throat zones (22). The fuel valve rod (152), Figs. 17 to 20 (not shown), may have a tapered slot (152) which is axially movable with throat area variation and rotatable by a bi-metal element (150). The cross-sectional area ratio between the zone 22 and the end of the downstream zone 24 is between 1:3 and 1:20 with the angle of divergence in the zone 24 of each of the members 16, 18 being up to 2 degrees and each of the members 12 and 14 being between 2 and 5 degrees.

Title: Improvements in or relating to apparatus for trimming and grooving plastic clay pipes
IPC: B28B21/96
Filed: 1951-11-19
Abstract: 700,955. Conveyers. BOWNE, M. S. Nov. 19, 1951 [July 21, 1951], No. 27072/51. Class 78 (1). [Also in Groups V, XXIV and XXXVII] A conveyer 2 brings a plastic clay pipe 14 to an intermittently rotating turret 8 (station A, Fig. 4, plan view), clamps 176 on the turret seize the pipe and swing it through 90 degrees to station B where a finishing operation is performed upon it (see Group V), then the clamps swing through another 90 degrees to station C where the clamps are released and the pipe drops a short distance on to a conveyer 3 which takes it away. Conveyer 3 runs continuously, but conveyer 2 stops immediately it has presented a pipe to the clamps at station A, being restarted when the pipe has reached station B. Conveyer 2 is driven from conveyer 3 by a clutch 22. Pipes are presented one after another by the conveyer 2, and as each pipe arrives it operates an electric switch 12 which disengages the clutch and initiates the clamp-closing, turretmoving and pipe-finishing operations. Conveyer 3, Figs. 26 and 27, comprises a pair of spaced sprockets 366 carrying chains 367 to which steel slats 370 are secured by angle brackets 371. The ends of the slats slide on side channels 362. To the frame of the conveyer is secured an electric motor 21 which drives the sprocket shaft 364 by means of chain 373 and sprocket 372. Conveyer 2 is similar constructed and is driven by chain 355 from sprocket 382 loose on driven shaft 365. Sprocket 382 is coupled to shaft 365 by clutch 22, which is disengaged when a lever 385 fulcrummed at 387 is rocked by link 392 and hydraulic piston 394. The conveyers are adjustable in height on a base frame 34, being for this purpose carried by brackets 358 having slides 357 which engage dovetail ways 356 in the base frame. The brackets 358 are secured to another bracket (not shown) which may be raised and lowered by means of a jack screw. The whole apparatus including the turret and the conveyers may be transported on wheels 36 or raised off the ground to set it in position by means of screws 37. Piston 394 is controlled by switch 12 and another switch (not shown) forming part of an electric circuit which actuates solenoids which control the valves of a pneumatic system. This pneumatic system includes cylinders 17 having rods which act on the clamp levers 177 fulcrummed at 179 and disposed between spaces plates 171 fixed on the turret 8.

Title: Data processing system
IPC: G06F11/267
Filed: 1971-04-19
Abstract: 1334262 Data processing; error detecting arrangements INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [20 April 1970] 27183/71 Heading G4A A data processing system includes a main store for instructions and data, a control register for receiving instructions, a processing unit, two local stores for receiving, storing and transmitting words (instructions and/or data) in duplicate, and a diagnostic system which includes a file of instruction and data words which are selectively supplied to the control register and the local stores, and an inhibit device for disabling under the control of the control register, one only of the two local stores so that different words may be stored in the two local stores, e.g. actual and expected processing results for comparison. When the system is controlled by the console file 10 which may include a read only disc, memory instruction words are transferred from the file 10 to the control register 24. Data words are transferred from the file 10 to the local stores 12, and 14, via registers 28, to a register 30, to the arithmetic unit 44, the output register 46, and the assembling and gating circuits 34, 20 and 22. Under processor control instruction words are passed from the control store 36 to the control register 24. In normal operation the contents of the local stores 12, 14 are identical and this may be checked by reading the store contents to the exclusive-OR check circuit 48. Comparison is made on a 36 bit word basis, i.e. four eight bit bytes and associated parity bits. Data transmitted to the local store A from output register D may be checked against the data received by store A in the exclusive- OR check circuit 52 by means of the latches 50. In response to a bit in the control word passed to the diagnostic gating circuits 40, 42 and 20, the gating of data into the local store A may be inhibited. This feature may be utilized in a number of operation modes. For example instruction words may be read into the local stores in duplicate and the A store 12 inhibited. The contents of the B store 14 are then replaced by microdiagnostic data words. The arithmetic unit 44 may then be operated by the instruction words in store A, with each instruction specifying the address of the next. This procedure allows faster operation than using the console file 10. Alternatively a table of expected results may be read into both stores A and B the A store inhibited and the actual results which are passed to local store B compared with the expected results by the check circuit 48. The check circuit 48 itself may be checked by a similar procedure in which different data are stored in the two local stores for comparison. The latches 50 may also be checked by reading data into store A and the latches, inhibiting store A, and passing the data via output register 46 for comparison in check circuit 52.
