Patent GB-649333-A (GB)
Title: Laundry apparatus for folding flat pieces of material
IPC: D06F89/00
Filed: 1947-10-18
Abstract: 649,333. Folding fabrics. SWIFT, J., and JENNER, Ltd., A. & C. Oct. 18, 1947, Nos. 27930/47 and 20152/48. [Class 42 (ii)] [Also in Group XL (b)] Laundry apparatus for folding flat pieces of material such as sheets comprises a feeding conveyer adapted to receive the work and feed it on to a work support capable of being reciprocated at uniform speed over substantially the whole of its stroke in a direction to impart folds to the work transverse to the direction of feed. As shown, articles are fed by a feeding conveyer 1 from a calender &c. 2 to a work support comprising transverse folding conveyers 3, 4 mounted on a carriage 5. Interruption by the leading edge of an article of a light beam B from a lamp 18 causes a photo-electric cell amplifier 19 to energize a motor 17 which acts through clutch mechanism, rack 15, and pinion 16 to reciprocate carriage 5 on rails 11. The work fed by conveyer 1 is thus laid in transverse folds on conveyers 3, 4 which at this stage,are stationary relative to carriage 5. When the tail edge of the work passes the beam B, cell 19 is again illuminated and motor 17 is cut off from this source of current ; the motor, however, receives a supplementary supply of current until a roller 20 on carriage 5 strikes an arm 21 on a limit switch 40, when the motor is braked and the carriage is arrested in the base position shown. A second limit switch at the opposite side of the machine is operated simultaneously with switch 40 and acts through a timing relay to start a motor 26 which drives folding conveyers 3, 4 to fold the work again in a direction at right angles to the previous folds, and deliver it via a further conveyer 5a to a receiving table 7 where a further folding operation may be effected manually. The transverse conveyers 3, 4 may be operated on a time switch with an automatic stop. The folding machine speed may be greater than that of the calender so that successive articles are sufficiently spaced. The drives to the various parts of the machine, instead of being automatically controlled, may be started and stopped by a machine operator. The folding conveyers may be replaced by a single conveyer or by a table or board, where articles are to be folded in one direction only.

Abstract: 804,377. Automatic control systems. LICENTIA PATENT - VERWALTUNG8 - G.m.b.H. Oct. 4, 1955 [Oct. 4, 1954], No. 28228/55. Class 38 (4). In an arrangement for detecting the size of a loop of strip or wire moving between sets of rollers, a portion of the loop is adjacent to a conductive plate of varying width so that variations in the size of the loop in opposite senses from normal vary in opposite senses a capacity formed in part by the strip or wire and the plate. In a rolling mill, Fig. 1, the material being rolled forms a loop between vertical rolls 2 and horizontal rolls 4 and passes adjacent to sickle-shaped metal plates 5 and 6 so that changes in loop size vary in opposite senses the capacities between each plate and the material of the loop. Each capacity forms part of a resonant circuit (not shown) supplied at a frequency differing from the resonant frequency and voltages varying in opposite senses produced by these two circuits are applied to a differential valve amplifier, the output of which controls loop size by controlling the speed of rolls 4. Capacity between plates 5 and 6 is eliminated by shields 7 and 8. Modifications in which variations of the two capacities are detected by means of a bridge circuit or in which a loop of non-conductive material forms a variable capacity by passing between a pair of shaped plates are referred to.

Abstract: 416,959. Signal lamps. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Lebby, S. L.; 81, E. 3rd Street, Corning, New York, U.S.A.) Oct. 19, 1933, No. 29006. Convention date, Dec. 9, 1932. [Class 75 (iv).] For use in signalling, particularly for use on railways to indicate the approach of a train to a level crossing, a pair of oppositely directed light projectors are rotatable at the same speed in the same direction about separate axes. In each lamp unit 10, the catadioptric reflector 30 and lamp bulb 28 are mounted on the table 25 carried by the shaft 24, which is rotated through intermediate gearing by the electric motor 43. The shaft 24 rotates in a bracket 19, which is insulated from the base 12 and supports a conducting cup 23 containing mercury and having a bearing in which the end of the shaft 24 rotates. Carried by and insulated from the reflector holder 29 is a similar cup 32 with mercury and a bearing for the stub shaft 33. The bulb 28 is electrically connected by a wire 53 to the cup 32, and through the bracket 26, table 25, and shaft 24 to the cup 23. The motor 43 has fixed field magnets 45 and an armature 46 mounted on a spindle 47 which is slidable axially under the action of a spring 49, so that, when no current is passing, the armature moves to a position not between the magnets 45, and so as to disengage the worm 40 from the worm wheel 39 on the shaft 38. The commutator 50 is so long as to be always,in contact with the motor brushes. On approach of a train, the circuits through the lamp bulbs and motor are completed, causing the armature 46 to move between the magnets 45 and so bring the worm and worm-wheel into engagement, and rotating the projectors to give a flashing signal. An arm 41 carrying a weight 42 is adjustably attached to the shaft 38, so that, when the motor stops, the weight rotates the shaft 38 and the light projectors into a predetermined position.
