Title: Improvements in or relating to a container for wound bobbins, and means for introducing bobbins into the container
IPC: B65H67/06
Filed: 1956-07-23
Abstract: 804,150. Collecting bobbins from winding machines. MASCHINENFABRIK SCHWEITER A. G. July 23, 1956 '[July 25, 1955], No. 22723/56. Addition to 751,995. Class 120(3) [Also in Group XVII] A container for collecting wound bobbins and means in conjunction with an automatic winder for introducing the bobbins into the container, as claimed in the parent Specification, is characterized in that the container is a magazine having flat sides and in that on the bracket of the automatic winder there is mounted a travelling support which accommodates said magazine and has means for accommodating a plurality of weft bobbin magazines (of the same form as the container) arranged upright in successive order with their flat sides disposed one against the other, with the object of successively locating each weft bobbin magazine over the magazine filling point, the travelling support being movable step by step by an amount equal to the spacing of the centres of a pair of such weft bobbin magazines an the support. As shown, a travelling support 40 is arranged to run along rails 4, 4a and comprises rods 43 in the form of loops which provide compartments for bobbin magazines 45 (e.g. A, B, C, D) which are suspended (e.g. by projection 45c) from the rods 43 in such a way that the rear wall of each magazine is disposed at an acute angle to the vertical plane, diverging downwards. For movement of the support 40 step by step a pawl 52 is moved backwards and forwards upon each bobbin change. Since movement of the support is to take place only when a magazine is full, whereas movement of the pawl 52 occurs upon each bobbin change, the pawl 52 is pressed downwards in the intervening period 'by a lever 65a. If a magazine has been filled to such an extent that a lever 57 reaches its dash-dotted position 57a, the lever 65a moves and the pawl 52 is released upwards to engage the lower edge 45a of a magazine and advance the support 40 by one magazine spacing Z. For accurate positioning, the support 40 is furnished at the rear with a rail 75 having indentations 75a which are engaged by a downwardly urged roller 77. Means is provided for stopping the winder when the last magazine D has been filled.

Magnetic modulating systems and apparatus. - A high-frequency conductor, comprising a non-magnetic core, coated or wound with a fine laver of iron, is used in a modulating system the characteristic feature of which is that both the highfrequency current to be modulated and the low-frequency or control current are both passed through the same conductor, the effective impedance of which is varied by the degree to which the iron coating is saturated by the magnetic field due to the control current. As shown in the Figure the high-frequency current is fed at the points k<1>, k<2> to a bifilar arrangement of conductors a1, a2, and a<1>1, a<1>2. The modulating current is applied at the points l<1>, l<2> which are preferably at equal high-frequency potentials. The conductor may be arranged in bifilar form as shown, or it may be zig-zag, or both, in order to lessen the magnetic flux not flowing in the iron.

[Also in Division G5] A telephone dialling accessory receives any one of a number of cards or plates 27 each bearing a telephone number and has a manually operable lever 2 movable at the conclusion of a dialling operation and a slidable visor 7 operable by the lever 2 to display successively each digit to be dialled. The visor 7 may be returned to its initial position after the complete number has been dialled. The card 27 is positioned between end flanges 3 and has perforations 5 enabling it to be located over screws 6 which also serve to secure the front and rear portions together. The visor 7 has an aperture 23 and is formed with a curved portion 10 engaging over a beading 9 on the casing front wall. A curved portion 8 terminates in a rearwardly projecting arm 10 from which a pin 11 extends downwardly into the casing into engagement with ratchet teeth 12 formed along the upper edge of a lever 13, normally maintained in position to be engaged by pin 11 by a leaf spring 24 fixed at one end to the lever 13 and bearing at its other end against the inner surface of the front wall of the casing 1. The lever 13 can be rocked against the resistance of the spring 24 to disengage the ratchet teeth 12 from the pin 11 for return of the visor 7 to zero position. The lever 13 is movable about pins 14 serving in co-operation with the screws 6 to secure the casing components together. This operation is effected by pressing an extension 15 of the lever 13 which projects through a slot 16 in the base of the casing 1. The lever 13 is capable of horizontal movement within limits imposed by two studs 25, 25a engaging in slots 26, 26a. Horizontal movement of the lever 13 is effected by stud 25a at the lower end of the operating lever which engages in slot 26a in the rear wall of the casing 1. Operating lever 2 is pivoted at a pin 17 in the casing back and its movement is determined by the slot 26a. A stop member 22 is formed integral with a rearwardly extending member 28 adapted to be inserted into the space between the casing of the telephone instrument and the finger stop. Alternatively the accessory may be mounted on a base constructed to receive the telephone instrument base. In use the visor 7 is set to display the first digit to be dialled. After dialling the digit the operator rocks the lever 2 causing movement of the lever 13 and ratchet 12 through the distance of one tooth whereby the visor 7 is moved to display the second digit. As this operation is completed the pin 11 passes behind a second ratchet tooth and the cycle of operations is repeated until the complete number has been dialled. The extension 15 is then moved to free the visor 7 for return by hand to its zero position.
