Title: Improvements in or relating to the continuous ringless spinning of textile fibres
IPC: D01H4/08
Filed: 1967-01-11
Abstract: 1,127,883. Break-spinning apparatus. VYZKUMNY USTAV BAULNARSKY. 11 Jan., 1967 [24 Feb., 1966], No. 1424/67. Heading DID. To reduce the number of combing-out rollers in break-spinning apparatus, one such roller is arranged to co-operate with two spinning- chambers and two feeding-devices, the drive to the latter being dependant in each case on the continuity of the yarn being spun in the corresponding spinning chamber, so that when there is a break in the yarn being withdrawn from one of the chambers, the drive to the corresponding feeding device is interrupted. A combing-roller 2 is disposed within a block I having on each side of it, a fibre-feeding device. Each device comprises la funnel 25 and a roller 19 Which feeds the sliver forward in tight formation on to the combing-roller, the two lots of separated fibres being delivered separately to oppositely-disposed channels 5. These deliver the fibres on to surfaces 7 of spinning chambers each having a collecting surface 8; air-escape apertures 10 and a fixed outlet tube 13. From this, yarn is withdrawn by rollers 14 to be taken up at 17. Between each take-up and pair of rollers is a feeler 15 which, when a break occurs, causes, through an impulse-member 22, the separation of a clutch 20 in the drive of the corresponding feed-mechanism.

Title: Improvements in or relating to web splicing
IPC: B65H19/16
Filed: 1963-01-14
Abstract: 1,025,954. Splicing webs. BELOIT CORPORATION. Jan. 14, 1963 [Jan. 29, 1962], No. 1618/63. Heading B6B. A web splicing mechanism has means for synchronizing the speeds of the expiring and replacement webs before splicing is performed. The replacement roll 12 is accelerated to the linear speed of web W from the expiring roll 10 by a variable speed drive 14. Optical tachometers 32, 33 each including a light source and photo-electric cell detect spaced black marks 30a, 31a on the ends of the roll 12 and a roller 29 over which the web passes. The outputs of the tachometers are fed to an electronic switch 34 connected to an oscilloscope 35, such that the waveforms 35a, 35b emanating from the marks 30a, 31a can be visibly compared. The oscilloscope is adjusted to render one waveform, e.g. 35a, stationary and the drive 14 is then adjusted until the waveform 35b is stationary. The splice is then performed by closing a switch 25, thus releasing a latch 26 by means of a solenoid 24. The splicing roller 16 is then actuated by a piston 18 within a pressure cylinder 19. Alternatively, upon closure of a switch 36a the drive 14 is adjusted automatically through a phase detector 37 and amplifier 38. Also, the solenoid 24 may be energized to release the splicing roller 16 by providing a marker on the end of the roll 12 with a detecting mechanism which ensures that the roller 16 presses the web W against the roll 12 as an adhesive strip 15a on the leading end 15 passes the roller 16.

Abstract: 1,205,421. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. Feb.6, 1968 [Feb.14 1967; May 10, 1967], Nos. 7010/67 and 21746/67. Heading G3R. A voltage regulator for use in a battery charging system on a road vehicle and of the type comprising a power transistor connected to control the field current of the vehicle generator is provided with a negative feedback path which stabilizes the overall gain of the regulator. As shown, the rectified output voltage of an alternator 11 is controlled in known manner by a regulator including a power transistor 29 which is connected in series with the field winding 31 of the generator and which is itself controlled by a signal, representative of output voltage variations, derived from a voltage divider 21, 22 a reference Zener diode 23 and further transistors 25, 27. A resistor 30 is connected between the emitter of transistor 29 and the base of transistor 25 to provide the required negative feedback, and the Specification explains how this arrangement stabilizes the overall gain of the regulator and thus helps to prevent the erratic operation which in some cases, and in the absence of such negative feedback, can arise because of the influence on the regulator action of the resistance of the leads connecting the regulator to the charging system. In a modification the emitter of transistor 27 is connected to output line 14 through a resistor, the emitter of transistor 29 is connected directly to line 14, and the feedback transistor 30 is connected between the base of transistor 29 and the base of transistor 25. The resistor 30 may have a value so chosen in relation to the characteristics of the transistor 25 and other circuit values that the battery voltage at which regulation commences varies with temperature in a desired manner.

[Jan. 26, 1953; Sept. 7, 1953], No. 2402/54. Class 83 (4). In a punching or a stamping machine in which a connecting-rod driven by a crank or an eccentric moves the tool carrying ram upwardly for the working stroke, the feeding mechanism is mounted on and moves with the ram. The feeding mechanism consists of two pairs of rollers whose grip on the metal strip being worked upon is released at the moment of punching or stamping. The driving shaft 7 carries a connecting-rod 9 having a ball end 10 engaging the ram 11 and a crank-pin 16 which through a linkage reciprocates an arm 27 pivoted on the ram 11. The arm 27 drives two pairs of rollers such as 34, 35 through a ratchet device and the driven roller 34 of each pair is subjected to a friction brake 39 constantly applied. The idling roller 35 of each pair is normally spring-urged to grip the strip but may be released manually by a lever 48 or automatically by a fixed cam 46 when the strip is punched or stamped. The pairs of rollers 34, 35 are mounted on blocks 11a adjustably secured on each side of the ram 11. In order to prevent buckling of the strip due to stretching when punched or stamped, the feed stroke of the pushing pair of rollers is made less than that of the pulling pair (not shown) by adjusting the effective length of the ratchet driving arm corresponding to arm 32. The length of the stroke of the arm 27 is alterable by varying the effective lengths of certain of the links and the radius of the crank-pin 16. The timing of the feed stroke is adjustable by angularly altering the position of the crank-pin 16.

In a process for making methanol synthesis gas in which a normally gaseous hydrocarbon is cracked in a furnace with steam and C0 2 , the C0 2  is obtained by recovery from the furnace flue gases after the gases have been freed of O 2 . The O 2  may be removed by reaction with other components in the gases by passing the gases over a Pt-group metal catalyst, the C0 2  being then scrubbed out by an absorbent, e.g. an aqueous solution of an alkali metal salt of a simple amino acid, which is regenerated by steam and recycled to the scrubber. The recovered C0 2  is delivered to the feedstock in an amount to provide an H 2  to C mole ratio of at least 2 and both are mixed with steam before going to the furnace. Purge gas rich in H 2  is taken from the methanol synthesis stage for mixing with the fuel supplied to the furnace burner, and flashed-off gas, including dimethyl ether, from the synthesis stage is delivered to the flue gas for reaction with the O 2 .
