Title: Method for producing artificial fibers
IPC: D01D5/30
Filed: 1965-10-18
Abstract: A bundle of artificial fibres comprising at least two sets of filaments made in different ways, and which may have different composition, may be drafted, cut and twisted, or false twisted, and then steam-heated to fix the twist, thereby producing texturised or elastic spun yarn.  The filaments may differ physically, e.g. in lustre or cross-section, or in shrinkability, so that a bundle which has been subjected to shrinking treatment may have one set of filaments protruding in loops from the bundle.  One set of filaments may have a Y-shaped cross-section. The filaments may be of cellulose derivatives, polyvinyl alcohol polyacrylonitrile, acrylonitrile copolymers, polyvinyl, chloride, polyvinylidene chloride, polyurethane, polyesters, polyamides, or polyolefins.  A filament may be formed of different polymers extruded in contact.

Title: Improvements in or relating to yarns and fabrics
Inventor: MEACOCK GRAHAM WALTER
IPC: D04H1/498
Filed: 1962-11-27
Abstract: In the manufacture of elastic yarn, (one- or two-stretch) woven fabric or "non-woven" fabric, "reactive" (i.e. of a high molecular weight synthetic linear polyamide or interpolyamide, e.g. poly-epsilon-caprolactum, partly drawn polyhexamethylene adipamide or the interpolyamide obtainable from hexamethylene diammonium adipate and epsilon-caprolactum in the ratio by weight of 80:20) discontinuous fibres and "unreactive" (e.g. cotton, wool, cellulose acetate, viscose rayon, polyethylene terephthalate, fully drawn polyhexamethylene adipamide) fibres or continuous filaments, all of which may be crimped, are first combined in proportions of 10-90% and 90-10% within a web, e.g. a carded web, or a composite yarn, which latter may form the whole or part of a woven fabric, or as the warp ends and/or weft picks of a woven fabric.  In the latter, any group of ten successive ends and/or ten successive picks includes respectively at least one end and/or one pick consisting wholly of one or more reactive fibres and at least one end and/or one pick consisting wholly of one or more unreactive fibres or filaments.  The web, composite yarn or fabric is then subjected to an application of a hot (at least 80 DEG C) non-aqueous acid polyhydric alcoholic liquid solution of formaldehyde for a time not exceeding forty five minutes to render the reactive fibres elastic, the other fibres being unaffected, and the resultant yarn or fabric is washed.  The weight of formaldehyde solution applied is equal to or greater than the weight of composite yarn, web or fabric.  The web may be formed by air-laying, wet-laying and/or by use of cross-lappers and consolidated, e.g. by dielectric heating and bonding perhaps locally in the form of a pattern, heat and pressure or needling. Layers of web, with the fibres thereof parallel or with the fibres of adjacent layers extending at right angles to each other, may be united by bonding.

Title: High-reliability digital data read/write system for magnetic tape in cassettes
IPC: G11B20/18
Filed: 1974-10-17
Abstract: 1490206 Writing and reading digital data FRANCE MINISTRY OF POST & TELECOMMUNICATIONS and COMPTEURS SCHLUMBERGER 17 Oct 1974 [19 Oct 1973 11 Oct 1974] 45018/74 Heading G4C In a device for writing and reading digital data blocks on and from magnetic tape cassettes 11, 12, each data block being in the form of characters having 8 data bits completed by a parity bit, each character is written serially twice consecutively, and a preamble character, 010101011, is written at the head of each block twice consecutively. Writing.-Digital data is delivered in parallel from a source 100 to a buffer register 5 by timing signals from a write timebase 2, the data and a parity bit generated therefrom by a generator 6 passing to a parallel-serial converter 7. Timing signals from the write timebase 2 cause the data from parallel-serial converter 7 and the preamble from a shift register 8 to pass via an OR gate 9 to a phase modulator-coder 10 whence the coded characters are written on whichever of cassettes 11, 12 is chosen by a routing circuit 13. Reading.-Characters from one of the cassettes 11, 12 are decoded in a phase demodulatordecoder 14, the decoded characters passing via a serial-parallel converter 15 to a preamble detector 40, a synchronization and release circuit 4, and buffer registers 21, 22. Should one or both preamble characters be detected by the preamble detector 40, signals are sent to the synchronization and release circuit 4 and to a read timebase 3 which initiate a true or false character sort circuit 20. In operation of the sort circuit 20, a character and its repeated character are read into the buffer registers 22, 21, respectively, their parity codes being checked by code verification circuits 26, 25, respectively, and the characters also being compared bit-by-bit in a comparator 27. If both even parity codes are true, the first character is gated out of buffer register 22 to a utilization circuit 16 by means of a selection circuit 23. If only one parity code is true, the character of true parity is gated out. If both parity codes are false and the characters are not identical bit-by-bit, the repeated character is gated out, and an error signal is produced which lights a lamp 28. In operation of the synchronization and release circuit 4, the preamble characters (of 9 bits in length or 1 cycle of the read timebase 3) are searched for during a period of 22 bits (or about 2¢ cycles). If preamble character(s) are sensed by the detector 40, signal(s) 51 are sent to the circuit 4, which synchronizes the characters by means of the preamble(s) and in turn sends a signal 55 to the read timebase 3. The latter then initiates the sort circuit 20 before the arrival of a first data character read signal 52 (at the end of the fourth cycle).

Title: Improvements in and relating to paper feeding apparatus
Inventor: WHEALS DAVID CHARLES
IPC: B65H20/04
Filed: 1965-10-26
Abstract: 1,113,796. Feeding webs. AUTO WRAPPERS (NORWICH) Ltd. 13 Sept., 1966 [26 Oct., 1965], No. 45236/65. Heading B6B. In apparatus wherein paper strip is fed stepby-step to a processing station such as a transverse cutter, the feed devices are operated by a driving member 7, Fig. 2, oscillated about a shaft 5 by a reciprocating driving member 14, Fig. 1, and the coupling between the members 7, 14 can be adjusted radially of the member 7 to vary the length of strip fed at each step for effecting registration of the strip relative to the operation of the cutter, such adjustment being controlled by means detecting marks on the strip. The strip is fed by rollers, the shaft of one of which has a gear-wheel 1 engaging a gearwheel 2 rotatable on a shaft 5 and coupled by a one-way ratchet device 3 to a member 4 rotatable on an extension 6 of the gear 2 and integral with the radially-extending driving member or arm 7. Slidable in a radial slot 8 in the arm 7 is a block 9 mounted on an extension 18 of a spigot 17 to which one end 16 of the driving member 14 is pivoted, the other end of the member 14 being adjustably connected to a driven crank-wheel 12. Another extension 25 of spigot 17 is secured in a radially-adjustable position to an arm 24 integral with a boss 22 which is rotatable on an eccentric 19. The eccentric 19 is rotatable on an extension 5a of shaft 5 and has a flange 21 with a stud 29, Fig. 1, thereon. A spring 30 connects the flange 21 and the arm 24 so that normally the stud 29 abuts the arm 24 and the parts 24, 21, 19 oscillate together about the shaft 5. A second stud 42 is mounted on the flange 21, and if a pivoted arm 40 is moved into the path of this stud, the eccentric 19 is prevented from rotating with the arm 24, thus causing radial movement of the arm and the spigot 17 and alteration of the step feed of the strip. The arm 40 is moved into blocking position by the energizing of an electromagnet 36. Registration marks on the strip are sensed and cause energizing of the magnet if a predetermined degree of out-of-register is sensed. Normally, the apparatus is set to slightly overfeed or under-feed the strip. In the former case, and as shown, the feed length is reduced by a correction, and in the latter case, the apparatus would have to be assembled with the eccentric 19 at 180‹ from the position shown. The flange 21 may have provision for mounting the stud 42 in either of a number of positions. Further, more than one stud 42 or alternatively a number of teeth may be provided on the flange 21, and the arm 40 operated to engage the stud 42 or tooth appropriate to the amount of misregistration to be corrected.

Title: Exercise apparatus
IPC: F16D65/28
Filed: 1973-09-27
Abstract: 1406342 Automatic control LIFECYCLE INC 27 Sept 1973 45291/73 Heading G3N [Also in Division A6]  Exercising apparatus comprises pedal means 11, 11 adapted for rotation by an exerciser, means for loading said pedals with a torque and means for controlling such loading to automatically provide at least three successive torque loads of sequentially increasing magnitude. The loading mechanism consists of a flywheel 12 suitably connected to pedals 11, a continuous band 16 which extends around flywheel 12 and a pulley 17 and is fixed to pulley 17 at point 18, and a cam 19 riding on belt 16 and rotated by control means 21 to adjust tension in band 16. The pulley 17 is biased in a counter-clockwise direction by spring 22. The arrangement is such that the greater the tension applied to band 16 the greater is the friction present at the surface of flywheel 12 and thus the greater torque load present at pedals 11. Concommittantly the greater friction load causes band 16 to tend to turn pulley 17 in a clockwise direction against the action of spring 22 and thus the angular movement of the position of pulley 17 is an indication of the torque load on pedals 11. The controlling means includes electrical bridge means 27 having two legs 29, 33. The leg 29 includes a programmed resistor 31 having a contact 32 which is controlled by a clock motor according to a set programme and, in series with resistor 31, a resistor 30 which can be set for a basic exercise level. The other leg 33 consists of a potentiometer 34 having a moving contact 35 which is coupled by linkage 36 to pulley 37. Bridge circuit 27, in operation, causes a difference in potential across moving contacts 32 and 35 and thus at the input to amplifier 26, when the moving contacts are not at the same relative locations on their respective resistances. Any output signal from amplifier 26 causes activation of servomotor 21 to move cam 19 until such signal is reduced to zero thus putting the necessary tension on band 16 to adjust the workload on pedals 11 according to the programme being followed by contact 32. The programmed resistor is controlled by the clock device to give a warm-up period in increasing stages of workload, a test period, a cardivascular stimulation period simulating cycling up hills of increasing height, a kinesthetic period and a warm-down period, Fig.6 (not shown) and the exercise level resistor can be set at various levels according to the athletic condition of the exerciser. The apparatus can include means for indicating the crank r.p.m. and calories per hour generated by the exerciser and can also incorporate means for indicating pulse rate and various other ancillary information, Fig. 5 (not shown). The apparatus can also include means for manually setting the load torque on the pedals.

Title: Process for modifying inorganic siliceous material to render it hydrophobic and organophilic
IPC: C09C1/30
Filed: 1962-12-06
Abstract: Finely-divided inorganic siliceous material, e.g. silica or clay, is rendered hydrophobic or organophilic by heating with an aliphatic aldehyde containing 3 to 10 carbon atoms, e.g. butyraldehyde, valeraldehyde, heptaldehyde, at at least 110 DEG C. The material may have a surface area of 1 to 200 m2/g and an average particle size of 10 to 40 mm .  The ratio aldehyde/material may be 12/1 to 5/1. Heating is effected for 2 to 4 hours, preferably at 135 DEG  to 300 DEG  C. under autogenous pressure.  Unreacted aldehyde is removed by heating in nitrogen or in vacuo at 150-250 DEG  C.  The coated material is said to be hydrophobic if not wet by boiling water over 30 minutes, and organophilic if, at a butanol/water interface, it passes into the butanol layer.  Analysis indicated the formation of a hydroxyl ester attached to the surface of the particles.
