Patent GB-467867-A (GB)
Title: Improvements in or relating to telephone and like signalling systems
IPC: H04Q1/32
Filed: 1936-04-27
Abstract: 467,867. Electromagnetic relays. STANDARD TELEPHONES & CABLES, Ltd. April 27, 1936, No. 11933. Convention date, April 27, 1935. [Class 38 (v)] [Also in Group XXXIX] A relay responsive to impulses over lines of widely different characteristics has one winding connected to the line and a second winding in series with a condenser which assists the operation and release of the relay. In Fig. 1, the impulse relay 36 is such that it releases readily and is in series with an auxiliary relay 33 which operates readily. Both relays are provided with biassing windings. When relay 33 responds to the closure of the loop, the discharge of the condenser 35 assists the operation of relay 36, and when the loop is opened, the discharge in the reverse direction assists the release of both relays. In Fig. 2, the impulse relay 13 controls a repeating relay 21. The operation of relay 13 is aided by the discharge of the condenser 20 as soon as its back contact is opened, and its release is aided by the discharge in the reverse direction as soon as its front contact is opened. The charging circuits ensure that relay 13 remains operated and released for certain minimum periods. The resistances connected to the biassing winding are such that the biassing current is a minimum when the relay is unoperated and a maximum when it is operated. The Specification as open to inspection under Sect. 91 comprises other arrangements. In Fig. 1 (Cancelled), a readily-operated auxiliary relay 23 completes the charging circuit of the condenser 25 which assists the operation of the impulse relay 26, the latter being readily releasable. In Fig. 5 (Cancelled), the condenser 521 controlling the impulse relay 56 is included in the anode circuit of a gas-discharge tube 522 of which the grid circuit is coupled to the line by a transformer 53. At each opening of the line loop, the positive potential on the grid ionizes the tube 522 and the condenser 521, which is normally charged, discharges through relay 56 and holds it momentarily. The condenser then begins to recharge and aids the release of relay 56. The tube becomes non- conducting on account of the shunting effect of the charging condenser. This arrangement, together with a filter circuit 54, 55 obviates false operation by surges. A modification of this arrangement is also described. A further arrangement is similar to that of Fig. 2 with the difference that only the release of the impulse relay is aided. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for welding flat blanks of thermo-plastic or thermo-plastic coated materials on to sacks or bags
IPC: B65B51/10
Filed: 1963-03-26
Abstract: 1,006,847. Securing thermoplastic sheets to articles. A. WINDMOLLER, and M. GEN. NERICH. March 26, 1963 [March 26, 1962], No. 11948/63. Heading B8F. [Also in Division B5] Blanks in the form of inserts or covers of synthetic plastic or plastic-coated material are welded on to continuously moving unheated sacks or bags by heating each blank in the areas to be welded during conveyance to the welding station and during further transportation the blank is placed on, and pressed into engagement with, the sack or bag as it passes the welding station. In the embodiment shown for welding inserts into the open bottoms of cross-bottom valve bags the inserts are cut transversely from a web 6 fed through rollers 7, 8, 9, 10, 11, 12 at a station 13, the cuts not extending completely across the web but being connected by bridges. The web 6 is fed to a cylinder provided with heating elements 2, 3, 4, 5, Fig. 3, in a surrounding jacket. The leading end of the web 6 is clamped against the element 2 by a rotating member 14 and impaled on a row of needles 15 on a bar 16 connected, through a lever 17, to a control shaft 18 operated by a cam 23 so that the needles 15 project through apertures in the element 2 during feeding of an insert. The peripheral speed of the cylinder 1 is greater than the speed of the web 6 so that the gripped insert is torn away from the remainder of the web. At the discharge position of the cylinder 1 the needles 15 are withdrawn and the insert is inserted by pressure into the open bottom of the flat sack, a support roller 24 being provided. Two further heating elements elements 25, 26 are provided and are each secured to a carrier 27, 28 so that they can be lifted by a magnet 29 when the machine drive is switched off. A switch (not shown) may also be provided to switch off the elements 25, 26 when pivoting takes place. The elements 3, 4, 5, 25, 26 may be adjustable perpendicular to their lengths to suit different insert sizes and the element 5 may be exchangeable. Each of the jacket surface portions 31, 33 may have a longitudinal groove of dove-tail cross-section extending parallel to the cylinder axis and in which the elements 3, 4 may be adjustably mounted. Alternatively, a row of thread holes, engaged by screws on the elements 3, 4 may be provided in the portions 31, 33. The heating elements may be heated directly by electrical resistances or by heating members arranged in the underlying jacket surface. The three jacket portions 31, 32, 33 are preferably heated independently of each other. Instead of being impaled on the needles 15 by the body 14 each insert may be clamped against the element 2 by a camoperated jaw.
