Abstract: 1381937 Yarns IMPERIAL CHEMICAL INDUSTRIES Ltd 8 June 1973 [27 June 1972] 30050/72 Headings D1F and D1W "Twistless" yarn which imparts a random marl appearance to fabrics and carpets made therefrom is produced by intermingling the filaments of each of at least two differently coloured or dyeable, optionally crimped, multifilament components, then entangling the components with one another and collecting the resultant composite yarn. An exemplary yarn having less than 0.1 turns per inch twist and which may combine three multifilament yarns of similar construction but of different dyeability and of similar or different materials e.g. polyamide or polyethylene terephthalate, possesses properties expressed inter alia as minimum values of "coherency factor" and "separation force" as measured according to described detailed tests therefor. Intermingling and entangling may be effected by fluid jet apparatus. As shown, spun multifilament yarns I and 3 of different dyeability withdrawn from packages 5, 7, by feed roll assembly 11, 13 (having been united at guide 9) pass over a drawing pin 15 to a draw roll assembly 17, 19, then are fed by nip rolls 21, 23, through a stuffer-box crimper 25, the crimp being set in chamber 27. Crimped yarns pass via a roll 29 and tensioner 30, splitter guide 31 to an intermingling air jet 33. The intermingled yarns pass through another splitter guide 37 unite at guide 39 and entangle in air jet 41 to form composite yarn which is wound into a package 47.

Filed: 1928-10-19
Abstract: 319,154. Soc. Alsacienne de Constructions MÚcaniques, and Roth, R. Oct. 19, 1928. Mules.-In a mule in which the tin roller shaft is driven by a differential gearing controlled by brakes which are applied to effect the drive for twisting and the reverse drive for backing-off, the brakes 4, Fig. 1, for the drum controlling the drive for twisting are mounted on levers 5, 6 connected by a spring rod 8, and are operated by a lever 7. The brakes for the drum controlling the drive for backing-off are similarly mounted and operated by a second similar lever. A cam 11 mounted on a shaft 12, which is turned at the end of the inward run by an arm 21 on the shaft engaging a stop 31, engages the arm 7 and applies the brakes 4. A catch 23 engages a locking-member 24 on the shaft to hold it in position, and maintain a spring 22 connected with the shaft in a stretched state. Towards the end of the inward run a bowl on the catch 23 engages a fixed member and lifts the catch, releasing the shaft 12 and allowing the spring 22 to rotate it in the reverse direction. A second cam on the shaft 12 then operates the brake controlling the backing-off. At the conclusion of the backing-off the bootleg rises and through a rod 29 and arm 30 turns the shaft 12 into such a position that neither brake is on, and the gearing is in condition for driving the tin-rollers for winding-on. The shaft 12 is also locked in position during twisting by a pawl which is lifted by the twist counter.

Title: Improvements in or relating to loud speaking telephonic receivers
IPC: H04R1/34
Filed: 1926-12-03
Abstract: 281,866. Rickets- W. J., and Paddle, L. R. Dec. 3, 1926. Loud-speakers.-A loud-speaker employing a large and preferably conical diaphragm is so constructed that, when it is not in use, substantially the whole of the diaphragm and its associated actuating means are protected from extraneous weather conditions by means under the control of an operator. Figs. 1 and 2 show a construction in which the conical diaphragm 1 and its actuating means 2 are housed within a casing 3 provided at one end with an opening 3<a>, the side walls of which are inclined in a downward and backward direction as shown. The opening 3a is adapted to be closed by a series of pivoted louvres 4 carried by a frame 5, each louvre being connected by a lever 7 to a common rod 8 adapted to be electramagnetically, pneumatically, or mechanically operated. As shown, the rod 8 is connected to one end of a pivoted lever 9, the other end of which is connected to the end of the core 10 of a solenoid 11 arranged vertically within the casing 3 and adapted to be energized from a distant controlling point. Alternative means for operating the louvres, Fig. 3, comprise a spindle 12 arranged at right-angles to the axes of the louvres and provided with a number of inclined cranks 13, each of which is embraced by a small bearing block 14 formed with spokes 15 pivoted to a ring 16, which is fixed to one end of the spindle 4<a> of the louvre 4. The spindle 12 is adapted to be partially rotated to close or open the louvres by electrical, pneumatic, or mechanical means. When a number of loud-speakers are being used, the electrical &c. means may be controlled from a central distributing point. Fig. 6 shows a modified construction in which the front end of the casing 3 is covered with a plate 17 having radial sectorshaped apertures, and a second similar plate is arranged parallel to and in close, contact with the plate 17. The plate 19 is pivoted centrally at 20 and is provided peripherally with a toothed quadrant 21, which engages with a pinion 22 adapted to be rotated by means such as an electric motor 23. When the actuating means 2 is of the moving conductor or moving coil type, necessitating the use of a direct current field winding, the exciting current may also be used to actuate the means for operating the louvres.
