IPC: D21G9/00
Filed: 1998-02-23
Abstract: A feedback-connected on-line regulation system for a headbox of a paper or board machine. The headbox includes a flow duct for stock suspension or separate flow ducts placed one above the other, each flow duct extending from an inlet header of the headbox into its slice channel. A stock suspension jet is discharged from the slice opening of the slice channel onto the forming wire or into the forming gap formed between forming wires. The regulation system includes a regulator unit and a set value unit. Measurement values are passed from the headbox system to the regulator unit and from the regulator unit, control values are obtained for controlling the actuators of the headbox system. The regulation system also includes an on-line If arrangement for measurement of the dried paper web or the paper web to be dried, and includes measurement of the distribution of fibers in the plane of the paper web. By means of the measurement signal obtained from this measurement arrangement, the actuators of the headbox are controlled by feedback so as to achieve a distribution of fiber orientation and a corresponding MD/CD ratio of strength in accordance with the set value in the paper web to be produced under control of the regulation system.

Title: A magnetic recorder-reproducer
IPC: G11B15/28
Filed: 1959-01-12
Abstract: 860,031. Keyboard switches. REVERE CAMERA CO. Jan. 12, 1959 [Jan. 31, 1958], No. 1025/59. Class 38 (5). [Also in Group XXXVIII] A magnetic tape-recorder is controlled by three " piano key," one slide and one rotary switches, mechanically interlinked, a change - speed lever and conventional electronic controls (not shown). In Fig. 5, 90 is a "stop" key, 50 the " record " key and 80 the "play" key. Figs. 7, 8 represent key 50. To prevent accidental erasing, a supplementary arm 70 is linked (Fig. 9, not shown) with a member 75, which must be displaced from under the edge 77 before the key 50 can be depressed. Apart from this additional safety feature, key 80 is similar. The keys are pivoted about an axis 52 and fingers 66, engaging a surface 68, form upward limit stops. A roller 55, mounted on a sliding lever 57, spring-biased to the left, travels over the cam surface 64-63-62 as the key is depressed, forming the lower limit stop as in Fig. 8. The fingers 66, moving with the keys 50, 80, rotate a lever 83 attached to the shaft 82 of the record/playback switch (not shown). When the keys rise, fingers 86, 87 forming part of the sliding lever 57, restore the lever 83 to its intermediate position, where circuitry (not described) is arranged to depolarize the record/ playback head. The " stop " key 90 is simply spring-biased upwardly by a spring 92 and its finger 66 (the one most to the right in Fig. 6) either acts on an auxiliary lever 89 whose opposite end partly returns lever 50, or acts on the end of the lever 83 whose opposite end partly returns lever 80. The roller 55, acting on the inclined tracks 64, completes the return of the keys. Similarly, the depression of either of the keys 50, 80 when the other is depressed cancels the other through the see-saw action of the lever 83. A centre-zero slide mechanism engages fast forward and rewind drives and in either fast drive position a bar (Fig. 4, not shown) rises under the edges 104 of the keys to raise them if depressed and to prevent their being depressed if a fast drive is engaged. Integral with the " mains on-off and tone control " is a cam (Fig. 4, not shown) which raises the same bar when in the " off " position and ensures that the switches are all returned to the raised position during non-use of the recorder. Specification 803,605 is referred to.

Title: Improvements in or relating to line-spacing devices for line-printing typewriters and like machines
IPC: B41J19/84
Filed: 1932-01-15
Abstract: 378,766. Typewriters &c. SWISS LOCOMOTIVE & MACHINE WORKS, Winterthur, Switzerland. Jan. 15, 1932, No. 1234. Convention date. Jan. 20, 1931. [Class 100 (iv).] Line-spacing mechanism.-In line-spacing mechanism for line-printing typewriters and like machines in which there is a relative movement between the platen and the composed type-line, a ratchet wheel is actuated during one of the movements and, after an inoperative period which is adjustable to vary the line-spacing, operates another ratchet wheel, which later affects feed of the sheet over the platen. The platen 22, Figs. 1 and 2, is mounted on a carrier arm 11 and moves up and down in the operation of printing. A ratchet wheel 1 is rotatably mounted on the platen spindle 22a, and a second equally toothed ratchet wheel 6 rotates on the hub 1a of the wheel 1. A driving-pin 5 on the wheel 6 moves in a slot 2 on the wheel 1, its movement being limited by adjustable stops 3, 4. Pawls 7, 8 mounted on the arm 11 prevent anticlockwise rotation of the wheel 1, and the wheel 6 is actuated by pawls 12, 13 mounted on an arm 14, pivoted about the hub 1a, and connected by a link 15 to the machine frame 16. A gear 19, fast to the hub 1a, actuates, through gears 20, paper-feed rollers 21. The position of the stop 4 in the slot 2 is fixed by a slotted disc 17, held in any desired position by a member 18, the numeral on the disc opposite the index line between the stops 4, 18 showing the corresponding feed in typographical points. As the arm 11 moves downwards, the wheel 6 is non-positively rotated anticlockwise by the pawls 12, 13, until the pin 5 strikes the stop 4, after which the pawls slip ineffectively over the teeth. During the return movement, after printing has taken place, the wheel 6 is rotated positively clockwise and, after an ineffective movement corresponding to the distance between stops 3, 4, actuates the wheel 1, and thence the feed-rollers 21, to give line-spacing. Since one tooth of the ratchets corresponds to a space of two points, two pawls are provided for each wheel, with a half tooth difference in length between them, so that an odd number of points may be spaced. The mechanism may be arranged so that feed takes place on the downward movement of the platen.

Title: Yarn texturising
IPC: D02G1/20
Filed: 1976-01-13
Abstract: 1525581 Friction false-twisting air interlaced yarn COURTAULDS Ltd 13 Jan 1976 {14 Jan 1975] 1499/75 Heading D1F A continuous multifilament yarn is interlaced in an air jet so that the filaments are coherently united at spaced apart points and then false twisted by a friction disc assembly under conditions of underfeed such that some of the filaments are broken between the spaced apart points. Preferably the degree of underfeed is 3 to 20% and the speed of the friction discs is higher than for simple false twisting, e.g. 4600 rpm for a yarn input speed to 140 m/min. A heater may proceed the false twister and a second heater of lower temperature may be used to develop the false twist crimp. A previously interlaced yarn may be taken from a store and false-twisted, or a fully drawn yarn may be supplied to an air interlacer placed before or after the first heater, or an undrawn or partially drawn yarn supplied to a friction disc draw-texturising machine may be used with interlacing taking place before or after drawing, the degree of draw applied being up to 20% greater than that conventionally used in producing fully drawn yarn. A second air interlacer may be positioned after the false twister. The degree of interlacing is preferably 20 to 40 knots/ metre. In the example a 167 dtex 80 filament polyester yarn is textured, the heaters being at 175 and 155‹C respectively. A two component yarn may be used, the first component being susceptible to breaking, e.g. cellulose diacetate or triacetate, regenerated cellulose or acrylic filaments, and the second component being polyester or nylon filaments. Alternatively the first component may be a low tenacity copolyester, e.g. a basic dyeable polyester containing sulphonate groups, and the second component may be a higher tenacity homopolyester. In a further alternative the first component filaments are finer and thus more easily breakable than the second component filaments.
