Title: Improvements in or relating to Traverse Mechanism for Yarn and like Winding Machines.
Inventor: WADE HAROLD
IPC: B65H54/10
Filed: 1917-11-02
Abstract: 120,261. Wade, H., (Universal Winding Co.). Nov. 2, 1917. Winding-machines.-In a traverse arrangement of the kind described in Specification 108,758 for winding cones of the kind described in Specification 108,757, [Class 120 (iii), Yarns &c.], the builder-arm 0 is formed with a cam face, which is engaged by a rotating arm 123, to vary the position of the track 112 and thereby alter the throw of the lever L, which governs the movements of the traverse bar E and guides G. The builder-arm 0 is pivoted on a stud 114 in a bearing depending from the framework and is controlled by a spring 133. The cam surface is formed with a convex portion 140 and, during the engagement of the arm 123 with this portion, the builder arm is raised and the throw of the bellcrank L is gradually diminished. A further portion 142 of the cam surface is concave, and whilst this portion is in engagement with the arm 123, the throw of the bell-crank is gradually increased again to its maximum. When the arm 123 leaves the cam surface, an adjustable stop 143 rests on a flat surface 144 on the bearing 126 of the arm 123 and the throw of the bell-crank L remains constant, but of a length greater than its natural throw, until the arm 123 once more engages the cam surface. The arm 123 is rotated from the cam shaft S<1> through spur and worm gearing 132, 130, 128. The cross lead 86 carrying the fulcrum of the lever L slides on guides 87, 88, the former of which is circular in cross section and the latter square. The guides G are attached to the traverse bar E, which has a depending portion 102 formed to engage a bowl 99 on the arm 96 of the lever L and with surfaces 106 adapted to engage spring buffers 151 and 147, the former being mounted on the machine frame 2 and the latter on the builderarm O so that its position may vary in accordance with the varying length of traverse. The friction drums driving the cones are mounted on shafts R, one at each side of the machine, and these shafts are driven by chain gearing from the main shaft. One shaft is driven through a sprocket wheel mounted direct on the shaft, and the other through gearing from a sprocket on a stud shaft. A sprocket on an adjustable bracket maintains the tension in the chain.

Title: Improvements in/or relating to the magnetic recording of pulses of low recurrence sequency
IPC: G11B5/008
Filed: 1966-04-13
Abstract: 1,145,489. Magnetic recording and playback. BUREAU D'ETUDES SCIENTIFIQUES ET TECHNIQUES. 13 April, 1966 [13 April, 1965], No. 16249/66. Heading G5R. Pulses of information separated by comparatively long pauses are recorded as erased portions interrupting a continuous prerecorded signal of a particular frequency, the record bearing also a reference track comprising a continuous prerecorded signal of the same frequency. On playback, both signals are read out to r comparator to produce a difference signal which is then demodulated. The comparator is used also for testing to ensure that the prerecorded signal is the same on both tracks, controlling lamps or other signals accordingly. The prerecording is carried out at a normal tape speed and the playback at a higher speed on the same apparatus, the pulse recording being effected at a much lower tape speed on a second apparatus in which the incoming pulses control a gated amplifier to which an erasing signal is fed.

Title: Systems for transmission of electromagnetic waves at very high frequencies
IPC: H01P1/16
Filed: 1939-06-02
Abstract: 529,539. Signalling through dielectric guides. STANDARD TELEPHONES & CABLES, Ltd. June 2, 1939, No. 16283. Convention date, June 29, 1938. [Class 40 (iii)'] A dielectric guide or transmission line is characterized by the provision of a filter element which allows the passage of a selected type of ,wave and stops all others. As shown in Fig. 2, the filter element is a quarter wave-length long and is terminated at each end by a network 3 of wires which are arranged transverse to the guide 10 so that they run in the same direction as the electric lines of force of the wave or waves to be stopped. This applies for instance to an electric wave of the type Eo, and also a magnetic wave of the type Ho, where the electric and magnetic lines of force respectively run parallel with the end wires. On the other hand the filter will pass a wave in which the lines of force are at right-angles to the network. Parasitic waves a, b, c, generated by the transmitter 5, Fig. 5, may, for instance, be blocked out by inserting a series of filter elements 1, 2; 2, 6; 6, 7, of appropriate length. In Fig. 6 an aerial 8 is attached to one filter network so as to radiate the stopped frequency. A succession of filters may also be used to eliminate any undesired wave-forms caused, for instance, by deformations 13, 14, Fig. 7 of the guide 10, or at parts where the guide is bent around a corner. The filter may also be used for preventing the passage of residual waves of one type after these have been nominally converted into waves of another type. For simultaneous working with two different types of waves, say Eo and Ho, one wave Eo is received at 15, Fig. 8, whilst the second wave Ho passes through the filter 10 and is received at 17. Waves of the Eo type from generator 23, Fig. 10, pass freely through the filter 21 and are transformed by a wave-converter 20 into waves of the Ho type, which then pass freely through the filter 22 which, however, stops waves of the Eo type. According to the Specification as open to inspection under Sect. 91, the distance between the two filter-elements may be varied to form an adjustable-impedance for matching different sections in transmission or reception. This subject-matter does not appear in the Specification as accepted.
