Abstract: 1373247 Open-end spinner; drive SCHUBERT & SALZER MASCHINENFABRIK AG 16 Nov 1971 [28 Nov 1970 21 June 1971] 53181/71 Heading DID [Also in Division H2] An open-end spinning machine is driven by a single motor controlled via potentiometers in parallel to provide a low motor speed used, e.g. during starting, bobbin changing or stopping. Motor 2, Fig. 1, drives fibre feed 13, spinner 1 and yarn draw off 26 and is controlled via potentiometers 4, 40 and change-over switch 41. The machine may include two switches connected in parallel, (Fig. 2, not shown) one switch being operated by a timing device, e.g. by a motor-rotated cam or by a timing relay. Alternatively potentiometers 4, 40 (Fig. 3) may be switched by parallel switches 44, 45, 46, switch 44 being operated by a timing device comprising cam 54, and switch 45 being operated manually. To stop main motor 2, potentiometer 4 is switched in by relay 47 via switch 46 to drive motor 2 at a lower speed, the relay also actuating coupling 62 to connect motor 2 to cam 6 which, after a predetermined time, actuates a stop switch. Cam 6 may be rotated by its own motor, and cam 54 rotated by motor 2. More than two potentiometers, or groups of potentiometers, may be used.

Mixture from the carburetter flows to the port 17 and the manifold 31 through passages 19 and 37, respectively. Air flow into the crank-case 20 is controlled by a throttle valve 55 linked to the throttle valve 51. The air flow through the passage 18 may enter the cylinder 11 through a separate inlet port (57), Fig. 5 (not shown), directing the air round the cylinder axis outwardly of the flow of mixture entering through a pair of ports (17). In another embodiment, Fig. 6 (not shown), mixture is drawn into the crank-case (20a) through a carburetter (60) and air is drawn through an inlet (66) into a long passage (64) in part defined in the crank-case. The mixture is delivered into the cylinder (11a) through the long passage (64) after delivery of the air. Air may be drawn into the crank-case (20a) and mixture into the long passage (64) by mounting the carburetter (60) on the air inlet (66).

Abstract: 1324426 Programmed control of textile machines E MAYER 2 Dec 1970 [5 Dec 1969] 57153/70 Heading G3N [Also in Division D1] An electric pattern attachment for a circular knitting machine incorporates a rotary transmitter 200 coupled to the needle cylinder of the machine and providing a synchronised binary signal sequence indicative of the position of each selector member of each knitting system. Signals A-F, indicative of the knitting systems, are fed through a decoder 310 to a programme switchgear P1 which is manually settable by a switch S1 to a main pattern. Signals G-L, indicative of the selector members in a knitting system are fed through a decoder 320 to a programme switchgear PII manually set by a switch S6 for a pattern repeat. The pattern repeat is programmed on a plugboard 400, by the use of differently coloured, or shaped, plugs for yarn colours, and is scanned by a wale counter ZA and a course counter ZB, coupled to a programme switchgear PIII. The switchgear PIII is connected to outputs 1-4 of switchgear PI and the counter ZA is stepped by timing pulses from a generator G which also steps the switchgear PI through a differentiating device 500. The switchgear PIII is connected via a common output line 510 to intermediate stores Zsp1-Zsp36 having additional inputs from switchgears PI, PII. Connected to the output of each intermediate store Zsp are magnetic amplifiers MV1-MV36 controlling magnetic devices MA1-MA36 each associated with a knitting system of the machine having electromagnetically actuated selector members for the needle jacks, or needles in the needle cylinder of the machine. Additionally, a manually set switch S2, through a decoder 330, determines the stitch count of the desired pattern repeat width in stores Zsp1- Z sp 36, and a manually set switch S3 through a decoder 340 sets the repeat height in the counter ZB. Switches 54, 55 enable a selective doubling of the repeat height or width through a mirrorimage scanning of the pattern repeat programmed in the plugboard 400. A switch T1, connected to the stitch course counter ZB initiates operation of the pattern attachment and resets the counter ZB to its first counting step.
