Title: Improvements in or relating to the treatment of cellulosic materials
Inventor: DUCKWORTH CLIFFORD
IPC: D06M15/423
Filed: 1967-05-04
Abstract: 1,224,164. Treating cellulosic materials. C. DUCKWORTH.  1 May, 1968 [4 May, 1967], No. 20797/67. Heading D1P. Cellulosic material is creaseproofed by impregnating it with an aqueous liquor containing a reactant resin and an acid catalyst, removing the material from the residual impregnating liquor, heating it in the wet state so as to effect wet crosslinking, drying it after heating without removing the reactant resin and passing the dried material to a curing stage in which dry cross-linking is effected. The material may be cotton fabric or a material comprising cellulosic fibres in admixture with wool, polyamide, polyester or acrylic fibres. The reactant resin may be an N-methylol compound or ether thereof, e.g. dimethylol dihydroxy ethylene urea or dimethylol ethyl triazone, which may be used in admixture with a compound which does not cross link with the cellulose in the heating stage, e.g. a melamine formaldehyde resin or derivative thereof, but contributes to the creaseproofing properties after curing. The catalyst may be an organic acid or mixture thereof with an acid salt or an acid salt, e.g. acetic, formic, oxalic or tartaric acid, magnesium chloride or zinc nitrate. The material may be impregnated with the aqueous liquor containing the reactant resin and acid catalyst and if desired a water repellent, rotproofing, softening or stiffening agent, excess liquid squeezed off on a pad mangle, heated while in the wet state e.g. by steaming with dry saturated steam at 100‹C, super-heated steam at atmospheric pressure at a temperature in excess of 100‹C or dry saturated steam at above atmosphere pressure and at a temperature in excess of 100‹C for less than one hour, dried at a temperature not in excess of 100‹C without neutralising or washing, optically made up into a garment, and cured at 140‹-160‹C.

Abstract: 614,606. Loading platforms. MOORE & CO., Inc., L. C. July 18, 1946, No. 21503. Convention date, July 31, 1945. [Class 78 (iv)] In an oil well pipe rack having a plurality of spaced parallel pipe-supporting beams resting on the ground, each of said beams is formed from a plurality of prefabricated, preferably interchangeable, truss members disposed end to end, and means such as cooperating pins and sockets detachably connect adjoining ends of said members which are preferably triangular. Pipe supporting beams 1, Fig. 1, which are disposed on either side of the walkway 2 leading to the floor 3 of the oil well derrick are, together with the walkway 2, constructed from a series of triangular prefabricated truss members 4, Fig. 3, resting on feet 9 and having at their apexes plates 11, Fig. 6, carrying pins 12 and bolts 17 which co-operate with holes 14 and 16, Fig. 5, in plates 13 secured to the vertical members 7 of the trusses which plates 13 also have holes 18 to which horizontal crossmembers 19 are secured.

Title: Apparatus for use in stator winding machines for positioning and fastening main and auxiliary wire guiding shrouds on grooved stator laminate packs of electric motors
IPC: H02K15/085
Filed: 1966-05-16
Abstract: 1,113,768. Stator winding apparatus. BALZER & DROLL K.G. 16 May, 1966 [15 May, 1965], No. 21563/66. Heading B3A. In a stator winding machine, apparatus for positioning and fastening winding formers on stator laminate packs 20 comprises a carrierplate 16 for the laminate pack which positions it coaxially of a needle-carrier 5, a plurality of wire-guiding shrouds, transversely divided into halves, on either side of the carrier-plate and movable towards each other, and a plurality of locking slides 40 on either side of the carrierplate which releasably secure the shroud halves to the laminate pack. Holders 56 are positioned on pressure plates 49, 50 to hold the main and auxiliary wire-guiding shrouds (70), (71) in the required locations, Fig. 2 (not shown). The halves 72, 73 of the shrouds are placed on the holders with a guide-rod 62 of the latter engaging in a guide bore 76 in each shroud half, and a nose 78 engages in an aperture 66 of a snapper 63 thereby locking it to the holder 56. The plates 49, 50 are moved towards each other and guide bars 90 of the shroud halves 72 enter bores in the shroud halves 73 until slots 92 in the bars 90 are in alignment with apertures 85, 86 in the shroud halves 73. Ribs 88 enter the axial slots in the laminate pack 20. The locking slides 40 are disposed radially around the pack 20, Fig. 2 (not shown), and the slides in alignment with the wire guiding shroud are actuated so that their tips 42 pass through the apertures 86 until they strike the lower ends of the snappers 63 thereby releasing the noses 78 from the apertures 66, Fig. 12 (not shown). The plates 49, 50 are next moved outwardly and spring-loaded bars 80, which were constrained inwardly by pressure-bar 68, move outwardly so that projections 87 engage in recesses 43 in the slides 40. The auxiliary wire-guiding shrouds are also withdrawn with the plates 49, 50. The locking slides adjacent the slots being wound are also extended to prevent deformation of the laminations during winding. After the inner coil has been wound the auxiliary shrouds are positioned in the same way as the main shrouds and the outer coil is wound. When all winding operations are completed, the plates 49, 50 are moved towards each other so that the holders 56 once more engage the shroud halves 72, 73. The slides 40 are moved radially inwardly by a small amount to release the projections 87 and the bars 80 are moved inwardly by the holder 56. The slides are then withdrawn and the snappers 63 reengage the noses 78 so that the shroud halves can be withdrawn with their holders to re-set the machine for a further winding operation. The carrier plate 16 is movable between two settings and is provided with two laminate pack-receiving bores (18), (19), Fig. 3 (not shown). As one stator is being wound an operator removes a wound stator from one bore and replaces it with a pack to be wound.

The method is based on the fact that the amount of bitumen adhered to a given weight of the fine components bears a known relationship to the amount adhered to the same weight of the coarse components.

Filed: 1952-08-28
Abstract: 722,371. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd. Aug. 21, 1953 [Aug. 28, 1952], No. 21652/52. Class 40 (4). In a communication system including a compandor wherein compression at the transmitter and expansion at the receiver are achieved by a network in both the signal path and the feed-back path of a line amplifier, the networks A and B effecting compression and expansion respectively in the signal path at each station are identical with the networks in the feed-back paths of amplifiers at the respective distant stations. Compression is obtained in the sender, Fig. 3, by rectifiers 1 and 18 shunted across the amplifier input and rectifiers 21, 22 in the feed-back path. The rectifiers are forward-biased by the rectified signal output appearing across a condenser 34 and reaction is avoided by the use of a hybrid transformer 19. The receiver, Fig. 4, has the A and B networks transposed and the rectifiers are biased by a potential derived from the rectified input signal. Alternative arrangements wherein network A follows the amplifier at the transmitter and network B follows the amplifier at the receiver are also described.

Abstract: 1,169,051. Vehicle seats. HALLAM, SLEIGH & CHESTON Ltd. 10 May, 1968 [10 May, 1967], No. 21704/67. Heading A4J. The seat proper of a vehicle seat comprises two L-shaped upholstered members 1 flanking a main upholstered part 3, and each L-shaped member 1 is angularly movable independently of the other. Each L-shaped member 1 is pivoted by a pin 12 to a slide (8) having a nut 19 engaged with a threaded rod 18 rotatably mounted in the fixed base 7 of the seat. Each L-shaped member 1 is also connected to the base 7 by a pair of parallel pivoted links 13. Rotation of the rod 18 causes the slide (8) to be displaced forwardly or rearwardly and in consequence the L-shaped member turns about its pivot pin 12. The front portion 4 of the L-shaped member therefore rises and falls in a substantially vertical plane. The adjustment may be made manually or electrically or hydraulically or pneumatically. A bench type seat may have a plurality of pairs of L-shaped members or only one pair for the driver. The L-shaped members may have forward dependent extensions for supporting the legs.
