Title: Improvements in or relating to the blending of fibres
Inventor: HOOPER NORBERT
IPC: D01G13/00
Filed: 1954-07-09
Abstract: 808,882. Automatic weight control systems. TWEEDALES & SMALLEY Ltd. [formerly TWEEDALES & SMALLEY (1920) Ltd.]. July 4, 1955 [July 9, 1954], No. 20201/54. Class 38 (4). [Also in Group IX] In a fibre-blending apparatus (see Group IX), the rate of feed of each of two or more laps of different fibre is adjusted in response to variation in weight of fibre to maintain a predetermined quantity of fibre per unit length of the lap. As shown in Fig. 1, a variable speed conveyer 25 delivers a lap on to a constant speed weighing conveyer 26 the upper run of which passes over a vertically-movable roller 28 serving as the equivalent of a scale-pan on an automatic weighing machine 29. Movement of the machine 29 in response to unacceptable variation in the quantity of fibre on the conveyer 26 rocks a contact arm 36, Fig. 7, to energize one or other of relays 40 and 41 to connect both resistances 44 and 45 in series with a motor 47 (driving the conveyer 25) or to short circuit both resistances (resistance 45 only normally remaining in circuit) so that the speed of the motor is correctively adjusted. Specifications 703,553 and 738,785 are referred to.

Abstract: 315,417. Electrical Research Products, Inc., (Assignees of Nyquist, H.). July 13, 1928, [Convention date]. Television.-In order that interference may be minimized between two adjacent television or like telegraph channels (for instance, in two-way television systems) scanning discs having differently arranged apertures are employed. Thus, if signals from a transmitter employing a scanning disc of the form a, Fig. 2, be picked up by a receiver employing a scanning disc of the form b, Fig. 3, the reconstituted pattern will not be recognizable Hence signals from a channel on which discs a are used will not interfere appreciably with the receiver in a channel on which discs b are used, since the line-elements of the pictures will be scanned in different orders in the two cases. For secrecy, the arrangement of apertures in the discs may be kept secret and changed from time to time.
