Abstract: 1,104,241. Toothed and belt gearing. JAMES MACKIE & SONS Ltd. 4 June, 1965 [25 June, 1964], No. 26341/64. Heading F2Q. [Also in Division D1] A yarn traversing assembly 24 can be positioned on either side of a winding spindle 2 depending on whether a clockwise or anticlockwise wind is desired, the angle between the axis of the spindle 2 and the axis of the yarn traversing assembly 24 being variable so that conical packages 8 can be wound. A motor 10, mounted on a plate 36 pivoted at 38, drives the spindle 2 via a belt 12. The spindle 2 drives the traversing assembly 24 via a gear train (44, 46, 48, 52, 54, 56, 58) (Fig. 3, not shown), and a toothed belt 66. The traversing assembly 24 is secured by bolts 32 to a bracket 30 coupled to a bracket 42. The weight of motor 10 acts on a chain 40 to bias brackets 42 and 30 clockwise (Fig. 2) to press a roller 26, carried by the traversing assembly, against the package 8. To transfer the traversing assembly 24 to the other side of the spindle 2 the bolts 32 are removed, the connection between the brackets 30, 42 is slacked off, and the bracket 30 swung clockwise to the other side of spindle 2 and the connection between the brackets 30, 42 retightened. The traversing assembly is rotated through 180 degrees in a horizontal plane and re-bolted to the bracket 30. To bias the roller 26 against the package 8 the chain 40 is passed over a pillar 74. To allow for the conicity of the package 8, the spindle 2 is pivotally adjustable about the vertical axis of rotation of the gear (46) (Fig. 3, not shown), which is meshed by gears (44, 48) secured to the substantially horizontal shafts 2, (50) respectively.

Title: Improvements in or relating to stamp issuing apparatus
IPC: A47F1/04
Filed: 1927-10-05
Abstract: 278,718. Landis et Gyr Soc. Anon., (Assignees of Rast, J., Kummer. F., and Pauli, F.). Oct. 6, 1926, [Convention date]. Tickets, issuing and cutting-off: registering number of.-Stamps are delivered from a roll 3 in strip form by operating a lever 17, the number of stamps to be issued being determined by a setting lever 19. The setting lever is provided at its upper end with a plunger 20 having a pin 21 to engage a selected notch 24 in a curved strip 23. and a mask 25 is moved by the lever to uncover the teeth of a ratchet-wheel 16, so that the forward movement of the lever 17 brings a pawl 18 into engagement with the ratchet-wheel and rotates it to an extent corresponding to the number of stamps to be issued. A toothed wheel 14 fast to the wheel 16 drives a feed roller 5 over which the strip 2 passes and the stamps are passed through an opening 8. At the beginning of the movement of the lever 17, an arm 39 carried by the lever opens a shears 7, and on the return of the lever, the arm closes the shears to sever the stamps, the shears being kept open during the movement by a spring &c. Means are provided to ensure that the stamps are severed at a line of perforations, a polygonal member 42 on the shaft 9 of the feed roller 5 being engaged by a projection 43 on a, slide 41 when a cam 44 on the lever 17 engages a pawl 45 on the slide to drive the slide towards the member 42 on the return of the lever. The roller 5 is thus rotated so that driving pins 10 on its surface are always brought to a definite position relative to the shears. When the strip 2 is exhausted or torn, a spring-pressed pin 46 is allowed to pass into recess 47 in the feed roller to prevent operation of the machine. A pressure roller 27, carried, together with counters 32, 33, by plates 34, is driven by gearing from the wheel 14, and is pressed on to the feed roller by a spring 36. The plates 34 may be swung out of the casing about the pivot 35, and one of the counters may be zeroized at any time. Springs 49 acting on a drum 48 prevent over-running of the feed-roller. The disposition of the frame 34 and the gear wheels driving the pressure roller 27 around the pivot 35 is such as to increase the effective pressure of the roller 27, thus lessening the possibility of tearing at the perforation points.

Abstract: 987.235. Radio altimeter; radio receiving circuits. STANDARD TELEPHONES & CABLES Ltd. July 21, 1961, No. 26587/61. Headings H4D and H4L. In a F.M. radio altimeter in which aircraft height is measured by counting the transitions of the beat signal (Fig. 2a) produced by mixing the transmitted wave with the ground reflected wave and then amplitude-limiting the product (Fig. 2b) errors in height-reading caused by interference signals such as A, B (which also operate the counter), are reduced by supplying the amplitude-limited beat signal (from terminals 1, 2, Fig. 1) to a second amplitudelimiter 23 feeding the counter (not shown) over a first path including an integration circuit 3, 8 and over a second path including a transistor 9. At low altitudes, representative of beat frequencies of 12 kc/s. and below, the transistor is held non-conductive by a bias derived by rectification at 12, 13 of the output of a lowpass filter 6, 11 supplied with the beat signal of Fig. 2b so that the input to limiter 23 comprises the beat signal after integration by 3, 8, as shown at Fig. 2, c, where the interference signal amplitude is reduced as shown at D. The latter is then removed by limiter 23, the output (Fig. 2, d) of which operates the counter. At frequencies of about 12 kc/s. and above, however, the amplitude of the integrated signal (Fig. 2c) becomes too small to be conveniently amplified back to a usable level by 23 and by correct adjustment of potentiometer 17 the blocking bias derived by rectification of the low-pass-filter 6, 11 output is arranged to chop sufficiently for transistor 9 to conduct at first only during the positive peaks of the beat signal and at about 15 kc/s. over the whole of each cycle of the latter. The input to limiter 23 from transistor 9 is reversed in phase with respect to the beat signal at terminals 1, 2 and Fig. 2e shows the waveform of the input to limiter 23 when the amplitudes of the signals fed via the integration circuit 3, 8 and via transistor 9 are equal. Interference signals now present may give rise to errors in height-reading but at the altitudes represented by beat frequencies above 12 kc/s. high accuracy is not required.
