Title: Circuit Arrangement for a Telecommunication, in particular Telephone Exchange
IPC: H04Q3/00
Filed: 1968-01-11
Abstract: 1,152,301. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Jan., 1968 [17 Jan., 1967], No. 1738/68. Heading H4K. In an exchange in which the switching equipment is divided into separate groups each of which has its own control circuitry, e.g. register/ marker, a central monitoring device is connected to each control circuit in order to start or inhibit the operation thereof in dependence upon the conditions currently existing in the other control circuits. The equipment groups comprise a plurality of line frames, e.g. TSG1 and a trunk frame RSG. A set of registers Rg, a translator ZO and a set of buffer stores PSp are common to the line frame groups and all of the groups are monitored by device MV. The latter is concerned with preventing the following simultaneous operations in the equipment groups:-route search by the trunk frame marker RM and route search by any line frame marker GM-although simultaneous routesearching by a plurality of line group markers is allowable; switching-through a selected path in more than one group at a time. The presence of a calling line T or trunk VL is detected by line scanner AS which-when the monitoring device allows under the conditions stated above-is connected via data bus IV to its line frame's marker GM. The latter then selects and operates a path through reed-relay switching frame Tln-K to a free junctor VS and from there via register-connector Rg-K1 (calling line) or Rg-K2 (calling trunk) to a free register. GM "informs" MV of each operation so that other group control circuits are not inhibited unnecessarily. When the full complement of digits (local call) or the first few digits (trunk call) have been inserted in the register, the translator ZO is seized and all the necessary data including called subscriber's group (local) or alternative routes (trunk) is then entered in buffer stores PSp. With the permission of MV, this data is passed via the data bus IV (ZV acts as an address bus) to the trunk marker RM and also to the relevant line marker in the case of a local call. (In the latter case route searching is allowed to proceed virtually simultaneously, but it is not stated how the markers "decide" between themselves which outlet from the trunk frame is to be used for the two searches). The arrowed leads on the righthand side of the line frame indicate the general path for a local call. In the case of a trunk call, the originally seized register is also connected to the trunk frame marker so that later dialled digits can be repeated via the seized outgoing junctor VS-g. The various control circuits "inform" the monitoring device at each step of their functions, i.e. start, route-search, switchthrough, release, so that other control circuits can be operated accordingly. Line scanning is stopped until a calling line or trunk has been switched-through to a register.

A rotary pump or motor comprising a stator and a rotor coaxially mounted therein to form an annular chamber therebetween subdivided by radially extending partitions into at least two working chambers and open-ended tubular vane members mounted in the rotor for radial or axial movement into and out of the working chambers and guided between side walls of the working chambers formed by flanges on the rotor or in part by a flange on the rotor and in part by the stator. In one embodiment, Figs.1 and 3, a stator 1 and a concentrically mounted rotor 3 form an annular chamber 4 subdivided by partitions 5, radially extending from the stator, into two working chambers each with an inlet 7 and outlet 8. The rotor 3 is formed with four equally spaced radial bores 9 slidably mounting open-ended tubular vanes 6 which are constrained to move into and out of the working chambers by means of the engagement of rollers 11, one connected to each vane by an arm 10 and bolt 20, in a cam-track 12. The tubular construction of the vane members permit a saving in weight. To improve sealing the external diameter of the vanes 6 is made greater than the distance 25 between radially extending flanges on the rotor 3 with the vanes seating in arcuate recesses 24-24 in the rotor flanges. The outer end of each tubular vane may be fitted with a pad of e.g., oil-proof rubber or bearing metal to enhance sealing. The outer peripheral surface of the cam groove 12 may include a layer of elastic material such as rubber. The vanes may also be moved radially, wholly or partly, by hydraulic means. The tubular vanes 6 may include a diametral strengthening web and may be of crosssection other than circular, e.g., square, rectangular or figure-of-eight. The outer periphery of the rotor 3 is sealed with respect to the stator 1. In another embodiment, Fig. 6, vanes 6 slide into and out of bores 9 whose axes are disposed parallel to the rotor axis. Two or more individual motors are shown combined into a single unit with partitions 5 at opposite ends of the stator 1 and the bore 9 of one motor aligned with and connected by a hole 26 to the bore 9 of the other motor. Alternatively, the partitions 5 may be located midway between the ends of the stator 1.

Abstract: 330,784. Bessler Disappearing Stairway Co., (Assignees of Bessler, F. E.). March 11, 1929, [Convention date]. Ladders.-An attic ladder is combined with a ceiling closure, the ladder being pivoted to one end of the ceiling aperture while the closure is pivoted to the sides or side of the aperture, movement of the ladder or closure causing movement of the other member, the ceiling closure being normally maintained shut. The ladder 13 is slidably mounted in a framework 14 pivoted at 16 to one end of a recess 11, which is adapted to be closed by a flap 12 pivoted to one side of the recess, springs 37 causing the closing movement of the flap. The portion of the ladder above the pivots 16, when in the non-operative position, is rather heavier than the other portion, so that the flap is maintained closed. The flap may be opened by pulling a chain 36 or by raising the upper end of the ladder to cause the lower end to press on bars 38 fixed to the flap, whereupon a toggle lever 25 pivoted at one end 26 to the flap and at the other end 27 to the framework 14 pulls the ladder to inclined position, Fig. 2, against the force of a spring 32 which controls the inclination of the ladder. The flap is retained in open position by the toggle lever 25, while the ladder can be further extended against spring resistance on a drum 40 on the framework 14 by the disengagement of a pivoted cam catch 17 from a stop 20 on the framework. To cause the ladder to disappear, it is raised on the framework until the pivoted catch engages over the stop 20, and then, by swinging the ladder upwardly, a stop 30a on it contacts with the toggle lever and bends the joint so that the force of the springs 37 may raise the flap, the ladder swinging to its inoperative position by gravity. In a modification, the aperture may be closed by spring-retracted flaps 12a pivoted one on each side of the opening, and the hand chain 36a is fixed to the ladder and passes through the joint of the flaps, the sides of the ladder contacting with inclined bars 38<a> on the flaps to maintain them in open position.
