Title: Improvements in or relating to a method for Regulating an Installation Producing Compressed gas and an Installation Employing said method
IPC: F04B49/24
Filed: 1967-10-31
Abstract: 1,160,620. Fluid-pressure servomotor systems: Automatic pressure control. AUTOMOBILES PEUGEOT. Oct. 31, 1967 [Nov. 10, 1966], No.49387/67. Headings G3P and G3R. An engine-driven compressor c has a suction valve 3 and delivers to a reservoir R where oil admixed with the air for cooling, sealing and lubricating purposes is separated for return to the compressor via 11 -15 and radiator 1. The air is supplied via minimum pressure valve 6 to distribution cock 5. During start-up, suction valve 3 opens and the engine dynamo 20 provides a current to close valve 14, and piston valve 9 moves to the left to allow additional oil return via 12 and restrict air return via chamber 10 in line a4-a5. When switches 17, 18 sense a predetermined delivery or suction pressure, one or both switches close to allow battery 24 to energize relay 23 to open switch 22 to allow valve 14 to open. Air now passes to engine speed control 13 to decrease engine speed, via line a6 to move piston 9 to restrict oil return and increase air return, and via line a7 to close the suction valve. This phase lasts while the engine is warming up. Thus, when the coolant temperature reaches, say 60‹ C. , switch 25 opens to isolate switches 17, 18 and allow switch 22 to close to energize valve 14 and thereby close the latter. As a result of this, the suction valve opens, the engine speed control 13 accelerates the engine and piston 9 returns to the left to increase oil return and decrease air return. The reservoir pressure now increases and supplies cock 5 via valve 6. At a predetermined maximum pressure, valve 15 opens to close switch 16 which energizes relay 23 to open switch 22 to open valve 14. Air can now pass to lines as -as to reset piston 9 to the right to decrease oil return, to close the suction valve and to reset the speed control to an idling position. Additionally, line a11 admits air to piston 11 to restrict air return. During shut-down, switch 21 is opened and the system is bled to atmosphere through valve 19. In a modification, valve 3, pistons 9, 11 and control 13 are controlled in a progressive manner.

Title: Drive apparatus for a carriage upon a guideway
IPC: B23Q1/48
Filed: 1964-12-04
Abstract: 1, 088, 858. Centrifugal blowers. LUWA A.G. Dec. 4, 1964 [Dec. 6, 1963], No. 49392/64. Heading F1C. [Also in Divisions F2 and F4] Relates to a drive whereby a carriage 2 for a travelling dust blower in textile winding, spinning and twisting machines, is moved backwards and forwards on a guideway 1, wherein an endless belt 13 is wrapped around driving and idler pulleys 7, 8 at the guideway ends and a pulley 6 on the carriage, and the driving or the carriage pulley has stages of different training diameter so as to effect a rolling movement of the carriage pulley on the belt and movement of the carriage. In such a drive, the blower impeller 4 is rotatable with, to utilize the rotation of, the pulley 6, and the direction of carriage movement is reversed, while the direction of rotation of the pulleys and the impeller is unchanged, by automatic means effecting relative shift between the belt and the pulley having stages of different training diameter. As shown, the pulley 7, fast on a driving motor shaft 10, is stepped and an elastic, e.g. nylon, belt engages a step 7a continuously and steps 7b, 7c, for carriage reversal, alternately, the steps 7b and 7c being respectively of smaller and larger diameter than the step 7a. Belt shift between the steps 7b, 7c is by a bell-crank lever 19 which carries belt shift rollers 20 and has connected thereto, directly, an abutment 21 and, through a rod 22, an abutment 24, these abutments being alternately engaged to rock the lever for reversal by engagement with the carriage ends. Reversal may alternatively be effected electromagnetically, as in Fig. 2 (not shown), or hydraulically, and the rod 22 may be replaced by a cable or chain. To utilize a belt of constant length the pulley 7 may be arranged with the steps 7a, 7c or equal diameter which is greater than that of the step 7b, and both belt loops engaging the pulley are shifted. To effect reversal should the carriage encounter an obstacle before reaching the end of its travel, in addition to reversal at the guideway ends, the pulley 7 may Figs. 3-5 (not shown) comprise two parts, one, consisting of the step 7a, fast on the driving motor shaft and the other consisting,of the steps 7b, 7c, screw mounted on said shaft, so that when the carriage encounters an obstacle, or cushions or buffers on the guideway ends, the steps 7b, 7c are screwed axially so that the belt, guided in fixed position rollers 20, is relatively shifted. Alternatively, the carriage may, through a cable guided over an idler, drive a small electric generator or centrifugal governor so that when the carriage is stationary, the voltage drop, acting via an electromagnet, or governor linkage effects belt shift. In Figs. 6-8 (not shown) the carriage pulley is stepped and guide rollers slidably mounted on the carriage are vertically displaced to shift the belt by the engagement with stationary cams, at the guideway ends, of the ends of a control plate connected to the guide roller shafts.

Patent GB-506673-A (GB)
Abstract: 506,673. Ignition systems. DELCOREMY & HYATT, Ltd., ROBINSON, E. L., and BLAZEY, S. H. Dec. 7, 1937, No: 33820. [Class 7 (iv)] In systems comprising a direct-current generator G and coil P, S, excessive current in the primary winding P at high speeds is avoided by the use of two interrupters a<1>, a<2> having overlapping periods of closure, the circuit of the interrupter a<1> being broken at a predetermined speed and voltage by a a cut-out R. In a modification, Fig. 2, the interrupters are arranged so that at low speeds the arm a<1> only is effective, but when the cut-out R removes the shortcircuit of the contacts controlled by the arm a2, the two interrupters are in series and the period of current-flow is that during which both are closed. By the addition of the connection shown in chain-lines between the left end of the coil P, Fig. 2, and the upper point X, and breaking the connection between the two points X, the interrupters may be used in parallel at low speeds with retarded ignition, the switch T being in its upper position. On placing the switch in its lower position, the interrupter a<1> only is effective, giving normal timing, and when the speed rises sufficiently for the cut-out R to operate, the interrupters are placed in series, affording a short period of flow and normal timing.
