Title: Non-woven fabric
IPC: D04H1/72
Filed: 1974-05-03
Abstract: 1495564 Layered cross-lapped webs IMPERIAL CHEMICAL INDUSTRIES Ltd 24 April 1975 [3 May 1974] 19445/74 Headings DIN and D1R A non-woven web 16 having a number of staple fibre layers 22, 24 which lie essentially parallel to the surfaces of the web, each layer of fibres having properties which differ from the properties of the adjacent layer or layers of fibres is produced by forming a feed batt comprising different zones 4, 6 of staple fibres arranged across its width with each zone extending through out the thickness of the feed batt, advancing the feed batt to a crosslapping apparatus comprising a reciprocating feed station 10 and a collector surface 14 advancing in a direction substantially perpendicular to the direction of reciprocation of feed station 10 and cross-lapping the feed batt so that the distance 18 advanced by the collector surface during one cycle of the reciprocating feed station is less than the width of the narrowest zone (zone 6) and the width of the feed batt divided by the distance advanced by the collector surface in one reciprocation of feed station 10 is an integer. A web of uniform mt/unit area is thereby obtained. The different zones may have fibres of different denier, crimp, length or chemical identity. One or both layers may be blends of fibres. A number of batts may be produced individually by carding, garnetting or air laying and then bringing the batts into side by side relationship (Fig. 3 not shown). Alternatively the feed hopper (50, Fig. 4 not shown) of a carding, garnetting or air laying machine may be divided by one or more walls (52) and different fibres supplied to the different compartments. A multizone feed batt is thereby produced. There is some intermingling of fibres at the zone boundaries, the intermingling being greater with air laying than with carding or garnetting. The multilayer web 16 may be stabilised by needling, impregnation with adhesive or by rendering adhesive fibres or a component of fibres by heat, a solvent, a plastisiser or a combination thereof. The antogenous bonding may be facilitated by pressure. One product has surface layers of high quality fibres and an inner layer of cheaper fibres. A blanket has a central, stronglybonded layer with surface layers which are only slightly bonded but are anchored by bonding and intermingling to the central layer.

Title: Improvements in or relating to the manufacture of organic acids and esters
IPC: C07C51/12
Filed: 1936-07-13
Abstract: Carboxylic acids and esters are made by reaction of a saturated monohydric aliphatic alcohol with carbon monoxide in the presence of a boron halide, e.g. boron fluoride, the reaction when carried out in the liquid phase being effected substantially in the absence of water.  The reaction may be effected in the liquid phase from room temperature up to about 350 DEG  C., preferably 180--240 DEG  C., and from atmospheric pressure up to 1000 atmos. or more, preferably 350--750 atmos., or in the vapour phase, preferably at 200--400 DEG C., and at 25--900, preferably 350--700 atmos.  Substances promoting the activity of the condensing agent such as metals or metal oxides, e.g. nickel or nickel oxide, may be present.  The vapour phase reaction is advantageously carried out in the presence of water vapour.  The reactant vapours may be led over activated charcoal. Carbon monoxide from commercial sources may be used, preferably after removal of sulphur compounds, metal carbonyls and like impurities but containing inert gases such as nitrogen.  Suitable alcohols comprise methyl, ethyl, propyl, butyl, including the secondary and tertiary alcohols, hexyl, and octyl alcohols.  The reaction apparatus may be of acid-resisting alloy steels or chromium or silver plated inside. In examples: (1) boron fluoride is absorbed in a molecularly equivalent weight of methanol in an autoclave.  Carbon monoxide is added till the pressure is 700 atmos. and temperature maintained at 200 DEG  C. to form acetic acid; (2) ethanol similarly gives propionic acid; (3) a gaseous mixture containing 85 per cent by volume of CO, and 5 per cent each of C2H5OH, H2O, and H2, is passed with about 2 per cent BF3 over activated charcoal at about 325 DEG C. and 700 atm. to yield acetic acid.  Specification 310,438, [Class 2 (iii)], is referred to.  The Specification as open to inspection under Sect. 91 comprises the use as condensing agents of hydrofluoboric acid or oxygenated acids obtained by reacting HF with boric acid or borates, e.g. as described in Specification 478,085, [Group III].  It includes also the preparation of polycarboxylic acids from polyhydroxy alcohols such as ethylene or propylene glycol or glycerine.

Title: Improvements in modulated carrier wave communication systems
IPC: H04J1/04
Filed: 1936-07-14
Abstract: 462,436. Multiplex systems. DEKKER, J. M. D. July 14, 1936, No. 19579. Drawings to Specification. [Class 40 (iv)] In the system described in Specification 456,270 in' which the channels are paired by modulation and suppression of different side bands so that the original high frequencies of a pair become adjacent, two separate selective circuits or filters for each pair are used instead of the common filter in the prior Specification. As the narrower band filters can be made with better characteristics than wider filters, the spacing between different pairs of channels may be reduced, or cheaper filters may be used. The spaces between the pairs may be wide enough to cover the suppressed side bands, the receivers being operated without audiofrequency filters.

Title: Improvements in or relating to the winding of synthetic textile filaments or yarns
Inventor: WILLIAMS ERIC
IPC: D01H1/40
Filed: 1963-05-18
Abstract: 1, 033, 202. Spinning process and apparatus. BRITISH NYLON SPINNERS Ltd. Mav 4, 1964 [May 18,1963], No. 19861/63. Headings DID and D1F. To prevent breaks and entanglements and to minimize waste when starting a winding operation particularly one following the application of heat to running filaments in a drawing, false-twist crimping, or length-stabilizing operation, while the initially-delivered yarn is wound on to a wastereceiving part of a bobbin, the necessary winding tension is established by restraining the free rotation of the traveller, and the bobbin may be caused to rotate at a speed below that of normal operation At the end of the starting-up period, the bobbin speed is increased and the traveller freed from the restraint. As shown, yarn passes from a pair of delivery-rolls 2, 3, over a heated snubbing-pin 4 to a pair of drawing-rolls 5, 6 and is wound on a spindle 11. At the start of an operation, the bobbin is rotated at low speed by an auxiliary motor through an over-running clutch, and with the ring- rail stationary below its normal operating position, the yarn is taken up on a waste-sleeve 4. The tension of the yarn is increased by a leaf-spring a pivoted rod, or an annular bush 15 fixed to the frame and arranged between the bobbin and the traveller; as the yarn is engaged by the spring, the tension rises until the yarn can push the spring &c. aside, when the traveller performs one revolution and the process is separated. When the machine is ready for normal operation, the ring rail is raised clear of the spring and above the waste-spool and the speed of the bobbin is increased to normal, the clutch permitting the low-speed auxiliary motor to free wheel. In the case of a false-twisting and drawing apparatus such as that described in Specification 890, 053 the spring 15 is replaced by one acting directly on the traveller.

Title: Printed circuit baseboard
IPC: H05K1/02
Filed: 1975-05-12
Abstract: 1468132 Printed circuits DAINI SEIKOSHA KK 12 May 1975 [13 May 1974 22 July 1974] 19882/75 Heading H1R [Also in Division G3] A printed circuit baseboard of e.g. glass epoxy resin has spaced through holes 11, 12 plated at 13, 14 to form conductive members of a printed circuit of the baseboard; plating 13 connecting members 15, 16 in opposed faces of the board and plating 14 connecting members 17, 18. An elongated aperture 27 of length exceeding the diameter of the through holes extends transversely of a line passing their centres between opposite sides of the board, and its width is exceeded by their diameters. Thus the leakage path between members 16, 18 is extended and the insulation between plating 13, 14 is increased. The printed circuit is adapted to receive electronic components, e.g. of a timepiece or computer. In a modification (Fig. 2, not shown), an insulant based baseboard carries a printed circuit having spaced soldered electrodes respectively connected to adjacent electronic components, and an elongated aperture extending transversely of the line joining the soldered electrodes between opposite sides of the board, with a length exceeding its width and a width less than the diameters of the soldered portions; so as to increase the insulation between the latter. In a further modification (Figs. 3, 4), an insulant baseboard 30 has two plated through holes 31 forming conductive members of a printed circuit baseboard insulating the through hole platings, and provided on its opposed surfaces by electrodes 33, 34 surrounding the through holes. A quartz crystal vibrator 35 with terminals 36 is mounted in the through holes 31; solder 37 interconnecting the terminals 36 with electrodes 33. An elongated aperture 40 is e.g. cut through the baseboard 30 between the platings of the through holes of length exceeding width to increase insulation therebetween, and the assembly is applicable to a timepiece.

Title: Improvements in or relating to electric secret signalling systems
IPC: H04K1/04
Filed: 1949-07-29
Abstract: 663,435. Secret transmission. WESTERN ELECTRIC CO., Inc. July 29, 1949 [Aug. 5, 1948], No. 19995/49. Addition to 624,296, [Group XL (c)] Class 40 (iv). [Also in Groups XXXV and XL (c)]  In a secret signalling system as disclosed in the parent Specification, the change - over at the receiver of the demodulating carriers is automatically synchronized with the carrier changes of the received signal. The signals received at 50 are passed via a band-pass filter 52 (to remove the " false carrier ") to a demodulator 54 to which is also applied the correct demodulating carrier generated at 56 or 58 and switched via amplifier 60 or 62 under the control of a switching multivibrator 88. The switching is correctly synchronized and phased relative to the changing incoming carriers by control pulses from a rate multivibrator 86 in turn controlled by a detector 76 and amplifier 84. The received " false " carriers are also applied through filters 64, 66, and amplifiers 68, 70 to gated limiters 72, 74 the gating period being normally arranged so that the change in " false " carrier occurs mid-way through the gating period. The output voltage (across condenser 81) of transformers T1, T2 and the detector 76 is then zero. If any deviation occurs, a signal (the polarity and magnitude of which will depend upon the sense and magnitude of the deviation) will appear across condenser 81 and be applied, via the contacts of relay 90 to the amplifier 84 to control the multivibrators 86, 88. The gating, controlled by a multivibrator 89, is also changed in phase until the carrier change occurs midway through the gating period since multivibrator 89 is controlled by a further multivibrator 87 in turn controlled by multivibrator 86 and amplifier 84. If either of the " false " carriers falls below a minimum amplitude, then amplifier 94 operates relay 92 to earth the input to the amplifier 84 to prevent spurious control of the synchronizer.
