Title: Telecommunications exchange equipment
IPC: H04Q3/54
Filed: 1973-07-26
Abstract: 1406369 Automatic exchange systems STANDARD TELEPHONES & CABLES Ltd 26 July 1973 35607/73 Heading H4K Switching network links are tested in groups by a traffic recorder which periodically tests each link for busy/free conditions and records the result. At the end of a test period, e.g. three hours, those links which do not have both a busy and a free entry in the record are deemed to be faulty and further manually controlled testing thereof is initiated. In the reed relay network denoted by reference SW, the P-wires of a group of 20 links are connected by a multiple MI via individual amplifiers TO to individual pairs of bi-stables BBx, BFx. The multiple may be a time multiplexor which periodically scans the links under clock control (Fig. 2, not shown), When scanned, the current condition of a link is recorded by illumination of a busy or free lamp. It would normally be expected that over a sufficiently long scanning period every link would be used and released at least once so that both the free and the busy lamps for such a link would be illuminated. Therefore, if only one lamp is illuminated it is assumed the link is faulty. In order to eliminate transients, a digital filter is used (Fig. 3, not shown).

Title: Improvements in blow pipes for the manufacture of glass bottles, jars and the like
IPC: C03B9/03
Filed: 1933-12-18
Abstract: 415,630. Glass manufacture. ANAYA, C., 137, Calle del Sabino, Mexico City. Dec. 18, 1933, No. 35646. Convention date, Dec. 17, 1932. [Class 56.] Relates to the manufacture of glass bottles which have an annular groove around the interior of the mouth to provide a seating for a cover or lid. According to the invention, a blow-pipe used in making the bottles is provided with a number of elements each of which can be moved radially in a plane at right angles to the axis of the blow-pipe in order to form the required groove in the mouth of a parison. The device comprises a tube 1, Fig. 1, having a sleeve 2 provided with two projecting arms 3 by means of which it can be turned relatively to the tube. The lower end or face of the sleeve 2 is provided with four spiral grooves 4 which engage pins 9<a> projecting upwards from four arcuate elements 8, Figs. 1 and 3, that lie on top of a ring 7. This ring is secured to the upper side of an annular projection 6 on a short tubular extension 5 secured to the lower end of the pipe 1. Each of the elements 8 is also provided with a pin 9 which projects downwards into a radial slot 10 formed on the ring 7. In use, when the parison has been formed around the blow-pipe, the sleeve 2 is turned by the arms 3, either by hand or by suitable means when the device forms part of a machine. The rotation of the sleeve causes the spiral grooves 4 to move the elements 8 outwards, and the elements form a groove around the inside of the neck of the parison. Rotation of the sleeve in the reverse direction causes the withdrawal of the elements to their original position and allows the blow-pipe to be removed from the parison.

Abstract: 1,077,855. Automatic thickness control. BRITISH IRON & STEEL RESEARCH ASSOCIATION Sept. 16, 1964 [Sept. 17, 1963], No.36510/63. Heading G3R. In a system in which means detecting the thickness of material at the roll gap of a rolling mill controls the mill to maintain a desired material thickness, the control is modified by a signal, dependent on the thickness of material at a point before it enters the mill, which is delayed by a period slightly less than the transit time of the material from the point to the mill. In Fig. 1, strip to be rolled passes from an uncoiler 13 through rolls 12 to a coiler 13A, and the thickness at the rolls is computed at 22 from electrical signals produced by a load detector 17 and a position detector 20 associated with a screwdown motor 15 as in Specification 946, 820. Computer 22 also detects deviations in thickness from a value selected by a manual control 21 and corrects small errors by controlling the speed of uncoiler 13. Errors greater than a value selected by a control 28 are also effective through a transistor gating device 27 to control the position of screw-down motor 15. Signals from an X-ray detector 26 measuring the thickness of strip leaving the rolls are also applied to computer 22 to provide correction for any long term drift. Signals from another X-ray detector 30 measuring the thickness of strip entering the rolls are applied through a filter 31 and differentiator 32 to derive a rate of change of thickness error which, after delay at 33 corresponding to a little less than the transit time from gauge 30 to the rolls, is applied to gate 27 to lower the signal level at which the gate is effective when input thickness is changing. The roles of the thickness detectors are interchanged when the material is passed in the reverse direction. A delayed input thickness rate of change signal may also be applied to the speed control system of uncoiler 13. In one modification the delayed input thickness rate signal is applied to the input of gate 27 instead of adjusting the level at which the gate is effective. In another modification the level at which the gate is rendered effective is adjusted in response to change in input thickness instead of rate of change, and in this case the original level is restored by a logic circuit responsive to the condition of computer 22 and gate 27 when thickness has been corrected.
