Abstract: 775,340. Centrifugal strainer separators. WESTERN STATES MACHINE CO. Aug. 5, 1955 [Aug. 5, 1954], No. 22663/55. Class 46. In a centrifugal strainer separator in which separated solids are removed from the walls of the rotating basket by a scraper or shoe arranged for vertical movement along the wall and pivoted about an axis spaced from the axis of the basket for movement towards and away from it ; an extension on the shoe engages the basket spindle assembly at a point remote from the pivot of the shoe to urge the basket wall away from the shoe in opposition to the force created at the assembly by the scraping operation. A square pillar 17, formed on one face with a rack adapted to be engaged by a pinion rotated by a hand wheel 36, carries a scraper shoe 38 and is itself mounted in a housing 14 pivoted on a vertical pin 15, the housing shaft and shoe being rotated by an arm 23 about the pin 15. A notch in a bracket 25 on the support 16 for the housing 14 retains the toe 22 of the shoe in a first operative position to remove a first scraping from the basket wall but may be moved further clock-wise until a stop 31 on a part of the housing 14 engages a face 32 of the bracket 25, bringing the toe to its nearest permissible position to the basket wall. The shoe 38 together with a guide' member 39 secured to it encircles the spindle 11 of the baskets and an arcuate face 41 on the guide member 39 and concentric with the pivot 15 of the housing 14 engages a sleeve 37 surrounding the spindle. The ends of the shoe 38 and guide member 39 remote from the toe 22 are secured together by a bolt 46 about which turns a stop body 45 adapted to engage the sleeve 37 with its front arcuate face and thereby transmit to it the force created by the scraping operation and tending to close the toe 22 on to the wall of the basket ; the wall thus tends to recede from the toe. Specification 628,082 [Group II] is referred to.

Title: Improvements in or relating to circuit arrangements for indicating single lines out of groups of lines having a common designation number, for example p.b.x. groups, in telecommunication switching systems
IPC: H04Q3/42
Filed: 1957-07-17
Abstract: 822,104. Automatic exchange systems. SIEMENS & HALSKE A.G. July 17, [July 19, 1956], No. 22690/57. Class 40 (4). In an arrangement for marking the first free line of a P.B.X. group, incoming digits defining the group are caused to fire one tube in each of three groups E1 . . . E10, Z1 . . . Z10, H1 . . . H10, thereby operating a gate to mark a point Ka1 individual to the group. This point is connected to a chain of change-over switches U2, U6, U8, each of which is operated or not in accordance with the busy or idle condition of an associated line of a group. The marking is thereby applied to the grids of one valve in each of two groups A1 . . . An, B1 . . . Bm to fire a combination of valves indicative of that free line. The make contact U8 of the last line of the group is connected to a line Lb, so that if all lines of the group are busy R 1 fires to operate a relay which initiates the sending back of busy tone. Individual lines of the group may be called by dialling codes appropriate to the points Ka2 or Ka3 which points are connected via decoupling rectifiers to the switches U6, U8. Prevention of the setting up of a call to a busy line may be effected merely by failure to mark any of the valves A1 . . . Bm, or alternatively by causing the firing of R1 to operate a relay L which disconnects the anode supplies from all the valves. In the last case the dotted connections shown may be completed between the moving arm and the back contacts of the switches U (e.g. U8) corresponding to the last line of the group. In this case toll-break in is made possible by the firing of tube R2 which operates X to disconnect the grid of the valve R1. In this case L fails to operate and if all lines of the group are busy, connection is established to the line corresponding to U8.

Abstract: 704,105. Automatic synchronizing control. GARRETT CORPORATION. Oct. 3, 1951 [Oct. 3, 1950], No. 23031/51. Class 38 (4) Two motors are maintained in positional synchronism by (i) using the phase-sense of the error signal to determine which motor is faster and then periodically interrupting its supply until the slower motor catches up, and (ii) by using the amplitude of the error signal to vary the ratio of the " on " to " off " times of the periodic interruptions to avoid overshoot and hunting as the motors reach synchronism. Detecting fast motor.-As shown, reversible two-phase capacitor induction motors 10, 11 are energized over reversing relay contacts 41, 42 manually controlled by a switch 62. The error signal (derived from A.C. energized potentiometers 103, 105 driven by the motors) is fed to the parallel-connected grids of a pair of valves 119, 120 which are biased towards cut off, and have their anodes A.C. energized in antiphase to form a phase-sense detector. Thus the signal causes one of the valves to conduct energizing relay 50 or 51 in the anode circuit to interrupt the supply to the appropriate motor. On-off control.-The relays 50, 51 also connect additional blocking bias to the valves from rectifier 140, through line 67 and R.C. delay network 145, 146, 147, which builds up a bias across capacitor 147 to cut the valve off and de-energize the relay in a time depending on the time-constant of the R.C. network, and the magnitude of the error signal. De-energizing the relay removes the bias supply, and the charge on the capacitor leaks off through resistor 146 until the valve conducts again and the cycle is repeated, Figs. 2, 3, 4 (not shown), with longer " off " and shorter " on " periods as synchronism is approached.
