A feeding mechanism for a carding engine is shown in Fig. 3, slivers 2a to 2f being selectively fed from cans, by aprons 6, under the control of an electronic system 11 which activates clutches 10 on a drive shaft 13. These clutches may be air controlled, electromechanical or electro-magnetic. A timer unit 12 which senses half cycles of a scratch feed carriage determines the feed intervals. A breaker or scribbler which produces batches of sliver for the carding engine may be run at twice the rate of the carder to build up a reserve of sliver. Combinations of the following are referred to for producing feed slivers:- wool, pre-chromed or other resist treated wool, mordant chromed wool, pre dyed wool, basic, deep dyed or acid dyeing nylon or acrylic fibres. Percentages of wool and acrylics are given.

Abstract: 960,376. Road trailer vehicles. R. BARTON. Sept. 30, 1960 [Sept. 30, 1959], No. 33149/59. Heading B7B. [Also in Division B8] A ramp 2 (Fig. 2), is pivoted at 16 intermediate its ends to a vehicle 1 so that it moves between the inclined position shown, and a roughly horizontal position as the load moves from one side of the hinge 16 to the other. The trailer illustrated serves for carrying a boat which is hauled up the ramp 2 by a line 37 passing over rollers 20, 19 to a winch 36. The rollers 19, 20 and further rollers 21, 22, on the ramp 2 serve to support the keel of the boat and, in the horizontal position of the ramp, are in alignment with further rollers 23, 24 on the trailer. The ramp has a cross-member 15 (Fig. 1), provided with standing brackets 29 for supporting rollers 25 carried on hinges 28 so that the rollers can adapt themselves to the shape of the bilges. Similar rollers 25 are carried in pivoted carriers on cross members 4 on the trailer. A bow stop 33 (Fig. 2) can be adjusted vertically and horizontally. The single axle of the trailer is provided with coil springs 9 and with friction or hydraulic dampers. Floats carried by arms secured by quick-acting fasteners to the rear of the ramp 2 may support the ramp in position for engaging a floating boat, and may carry spherical rollers for guiding the boat into engagement with the ramp. Several cross members 4 may be provided on the trailer, and more than one pair of rollers 25 may be mounted on each cross-member. In an alternative construction the ramp 2 is mounted so that, when horizontal, it is housed between the channels 5 forming the spine of the trailer; this permits the rollers 23 to have lower mountings.

Abstract: 646,732. Drying apparatus. COMBUSTION ENGINEERING - SUPERHEATER, Inc. Dec. 17, 1947, No. 33279. Convention date, Dec. 31, 1946. [Class 34(ii)] A drying system comprises a cage mill A into which the material to be dried is conveyed in a current of hot gas and thence through a drying column to a separator B, a damper C for deflecting the partly dried material back to the mill A or deflecting the completely dried material out of the system and a feeder D for supplying the wet raw material to the mill, the hot gas being heated by a heater E. The feeder is driven by a motor 18 which has control means operated in response to the position of the damper C so that when the material is being re-cycled the feeder means is inoperative but is started again when the dried material is discharged. Damper C and the feeder control may be operated by a clock-operated switch 26 which in timed intervals makes or breaks the electric current to solenoids 27, 28. The inlet temperature of the hot gases is controlled by cold air inlet dampers 30 responsive to a thermostat 33 which may also control the fuel supply to the furnace E.

Title: Improvements in or relating to control circuits for incandescent electric lamps for taking photographs
Inventor: NEALE DENIS MANKTELOW
IPC: H05B39/06
Filed: 1954-11-18
Abstract: 788,921. Photo-electric exposure control. ILFORD, Ltd. Nov. 16, 1955 [Nov. 18, 1954], No. 33489/54. Class 40 (3). [Also in Group XXXV] To reduce exposure errors, caused by afterglow of the lamp filament, when making short exposures with photographic printing apparatus of the kind in which the printing light transmitted, or reflected, by an original is received by a photo-cell, the current from which charges a condenser to a potential sufficient to operate a relay for switching off the lamp, the supply circuit to the lamp includes a series resistor of such a value as to effect a substantial reduction in the rate of heating of the lamp filament when it is first switched on, without seriously affecting its power when the final temperature of the filament is reached. Thus, during short exposures, the filament does not reach maximum temperature and the period of afterglow is, consequently, reduced, whilst for longer exposures, when afterglow is less important, the lamp operates at substantially full power, after a short initial delay occasioned by the resistor. The value of the resistor may be about twice that of the filament in its cold state. The lamp and resistor may be embodied in the apparatus described in Specification 788,920.

Pulleys and belt may replace the sprockets and chain. The clutch means 17 comprises a collar 17 axially movable of the shaft 10 by a pivoted yoke 18 and carrying radial pegs 16 which, when the roller is moved downwardly engage axial slots 19 in a sleeve 20 secured to the shaft 10 and axial slots 15 in a sleeve 14 to which both the gear 11 and the roller 12 are secured. The clutch device 36, 43 comprises a bar section key 36 slidable in a diametral slot 35 in a sleeve 30 (see Fig. 2, not shown), keyed to the shaft 25, so as, in one position, to project beyond the sleeve 30 and engage a peg 43 on the sprocket 31 to drivingly connect the sprocket 31 and shaft 25. The key 36 is held in this position by a spring- loaded ball detent and is movable into the disengaged position by a peg 37. A similar reversing arrangement is provided for lower, as well as the upper pair of rollers. Specifications 653,021 and 859,163 are referred to.

Abstract: 821,460. Twist-tubes etc.; crimping yams. SCRAGG & SONS Ltd., E. Jan. 14, 1958 [Nov. 3, 1956], No. 33600/56. Classes 120(2) and 120 (3) False-twisting apparatus comprises means for moving at least one yarn along a predetermined path and two or more movable surfaces disposed to contact the yarn from opposite sides of the path and displaced relatively to each other so as to make contact at successive positions along the yarn whereby the frictional contact of the surfaces operates to rotate the yarn and thereby impart false twist thereto. In a crimping process, a thermoplastic yarn passes through a heating zone preceding the twisting apparatus. As shown in Fig. 1, a belt 7 drives a pulley 6 to transmit, via gears 8 and 9, rotation to rollers which co-operate with freely-rotatable rollers 12 to carry endless belts 14 e.g. of rubber, between opposed runs of which yarn (guided by an eye 15) passes and is rotated by frictional contact therewith: co-operating pairs of rollers are mounted in brackets 11 having a control screw 13 whereby the position of the rollers may be adjusted to bring the inner run of the belts 14 in line, overlapping or clear of each other. In the apparatus of Fig. 4, yarn guided between eyes 15 and 17 is twisted by flanges on spindles 16: as shown in Fig. 7, the flanges may overlap. The movable surfaces may travel in planes other than normal to the yarn path.

A printing machine or a buckle folding machine 1, in which sheets 2 are prefolded is associated with a portable blade folding machine into which the prefolded sheets are fed to receive further transverse folds. The portable blade folding machine comprises two horizontal belt conveyers 3, 6 moving in opposite directions, and spaced from one another at the roller ends 4, 7 respectively, to receive a sheet deflector 5, which deflects the oncoming sheet between a pair of folding rollers 8, 9 rotatable about vertical axes and a folding blade 10, whereby the sheet is aligned against an arrester 11. The preceding machine, e.g. folding machine 1 controls the operating cycle of the portable blade folding machine and causes the folding blade 10 to force the prefolded sheet 2 into the nip of folding rollers 8, 9. The subsequently folded sheet is discharged on to the stacking support 12 and guide thereon by guides 13, 14, 15. A pusher 16, Fig. 3 (not shown) displaces the transversely folded sheets horizontally out of the folding zone. If the sheets 2 are to be folded transversely in a direction opposite to that above the portable machine is turned about so that the folding blade 10 is adjacent the preceding machine, Fig. 2 (not shown).
