Title: Process of degumming textile plants
IPC: D01C1/02
Filed: 1930-05-31
Abstract: Textile plants and vegetable matter are degummed by treating with a simple unsubstituted naphthalene sulphonic acid, with or without common salt, and neutralizing in an alkaline or a soap bath, or in a mixture of such baths, the product obtained being suitable for spinning or for manufacture into paper pulp.  In an example, crude hemp fibres from which the outer tegument has been removed by stripping or peeling, are soaked, and then immersed in a bath containing equal parts of sodium chloride and a naphthalene sulphonic acid, of strength 4 DEG  B<\>ae.  The fibres are allowed to steep for about 12 hours, and are then washed in running water and neutralized with a weak soap solution containing a small quantity of soda ash. The temperature of the bath may be raised to 60 DEG  C. for textile fibres for spinning purposes, the strength of the bath being reduced to 1 DEG  B<\>ae.  If paper-pulp is being prepared the temperature may be raised to 100 DEG  C.  Other fibres such as sisal hemp, flax, ramie, alfalfa, and jute may be used.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the treatment for "stripping" of spun and raw threads and fabrics in order to prepare them for dyeing and bleaching, the "stripping" constituting a second degumming.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to looms having stationary weft supplies
IPC: D03D41/00
Filed: 1927-06-27
Abstract: 273,332. Nicolet, W. June 28, 1926, [Convention date]. Addition to 262,962. Selvages, special fabrics with. - Relates to the method of of weaving described in the parent Specification wherein the warp threads pass through the holes in oppositelymoving combs 5, 7 and are thereby formed into two sheds, into which sheds wefts are passed simultaneously or nearly so, the front weft being beaten up first, whereupon the warp threads are moved and recrossed and then the rear weft is beaten up. In order that an ordinary 1 : 1 selvage may be formed, weft from one bobbin is taken alternately into the front and the rear shed and when the weft loop has been formed the weft is cut. Several bobbins may be used. The weft 9 may be introduced from the bobbin 33 into the rear and permanently open shed by a weft needle 20 furnished with an eye, whilst the weft is moved into the front shed by weft needles 21<a>, 21b situated at opposite sides of the fabric, acting alternately and furnished with grippers. When the eye of the weft needle is at the left, the needle 21a moves through the crossed front shed and its gripper seizes the weft, which is thereupon cut between the gripper and the selvage by a cutter 34. The needle then returns taking the gripped weft with it, and the weft thereby inserted into the crossed front shed is beaten up. At the same time the combs move apart and the inserted weft is thus incorporated in the fabric. Meanwhile the needle 20 moves from the position shown in Fig. 1 to that shown in Fig. 2 and inserts a weft into the rear open shed. A laterally disposed rocking hook 35 then pulls this weft into the path of the reed whereby it is beaten up, the combs crossing again to incorporate this weft and form a front crossed shed again. Afterwards the weft is gripped and inserted by the needle 21b and so on. The fabric produced is illustrated. Two weft bobbins may be used, two alternately operating weft needles 20 being used in the rear open shed. The fabric produced in this instance is shown in Fig. 3.

Title: Releasable electrical connector
IPC: H01R13/635
Filed: 1965-04-23
Abstract: 1,100,005. Quickly releasable connector. F. G. BAC. 23 April, 1965 [24 April 1964; 7 April, 1965], No. 17243/65. Heading H2E. Part B of an electrical connector is locked to part A in such manner as to be quickly releasable therefrom when the rocket or similar device to which the part A is rigidly secured, is fired. Contacts 136 are connected over double, ended contacts 124 carried by a dead face 121 movable against a spring 118, with contacts 113. The dead face 121 provides a seal between the outer atmosphere and the contacts 113 and the outer surface may carry a plate or grid (27) of heat-resistant insulating material. Rotation of ring element 145 causes part B to mate and lock to part A through balls 161 riding in helical grooves provided in a sleeve 137, held against the end of the part A, thereby moving ring 145 and body shell 128 of part B, via co-operating flanges 151 and 152, forwardly. This causes the forward part 130 of the shell 128 to push balls 140 into a groove 141 in the part A, i.e. to the position shown in the righthand half of Fig. 3, and so to lock the two parts together. In the releasing mechanism shown in the left-hand side of Fig. 3, a flanged ring 156 is pushed downwardly against the action of a spring 159, thus allowing the balls 161 to slip into the recess 163 and allowing the rings 144 and 145 to be moved downwardly under the action of the spring 149, the ring 145 pushing the shell 128 down with it. In the alternative release mechanism shown in the right-hand side, a fork 166 is removed so that the ring 1551 moves upwardly under the action of a spring 159, thus allowing the balls 161 to drop into the aperture 164. In an alternative embodiment (Fig. 4, not shown), a ring similar to the ring 155<SP>1</SP> is lifted upwardly either by explosive caps or by a blast of compressed-air. The rings 155 or 155<SP>1</SP> may be controlled by electromagnets, Figs. 5 and 6 (not shown), and in this case an inserted fork may be used as a safety lock. Moreover, the ring may have two inwardly-directed projecting lugs (209a), Fig. 7 (not shown), to hold the balls 161 in the grooves 160, and be maintained in the angular position in which the lugs contact the balls 161 by means of a pin (211). Release may then be effected either electromagnetically or by pulling a cable (217) to shear the pin and rotate the ring so as to free the balls 161.

Title: Improvements in Elevators for Blast Furnaces, Kilns or the like.
IPC: C21B7/18
Filed: 1917-11-23
Abstract: 111,673. Soc. J. Munier et Cie. Nov. 28, 1916, [Convention date]. Load, engaging, releasing, and depositing.-Relates to blast furnace &c. skip hoists, and comprises means for lowering the skip on to the furnace mouth, and for operating the skip cover. As shown diagrammatically in Fig. 2, the carriage track of the skip hoist has a portion 7 with diverging rails, which allow the skip carriage to tip and lower the skip to the furnace mouth. The skip carriage consists of a framework A, Fig. 7, having front and rear wheels 2, 3, of which the former engage only the main track 1 while the latter have two sets of flanges, one for the track 1 and the other for the upper diverging track a, b. The cable 16 is secured at 26 to a pulley wheel 25 freely mounted on the rear axle, while the twin cables 15 pass round fixed sectors 23. Secured at each side of the pulley 25 are disks 27 round which pass Galle chains 29 connected by a cross pin 30 to another Galle chain 31 passing round a pulley on the front axle and terminating in the skip suspension hook 33. The skip cover 42 is suspended from chains 37 secured to the rear axle, and passing over arms 36 free on the axle, but normally held from movement by stops 58 on the disks 27. Two pivoted flaps 44 on the cover are normally held open by chains secured to the links 40, but are allowed to fall to close the opening in the cover when the suspension chains are slack. A pivoted arm or bolt 50 normally prevents disengagement of the skip rod 55 from the suspension hook 33. The winding gear comprises a motor 71, Fig. 12, which drives through reducing gearing 70 - - 67 the drum F, and through an electro-magnetic clutch 85 and reducing-gearing 81 - - 78 the drum H. The twin cables 15 and the greater portion of the length of the cable 16 wind on to the portion 62 of the drum F, while the remainder of the cable 16 winds on to a portion 63 of greater diameter. When the carriage reaches the top of the track and begins to tilt, the cable 16 unwinds from the larger part 63 of the drum F. As the traction cable 15 is winding on the smaller part 62 of the drum, the cable 16 slackens, allowing the pulley wheel 25 with the disks 27 to turn and the skip to descend on to the furnace mouth. The cover descends at the same time, but more rapidly owing to the length of the arm 36, until it seats itself on the top of the skip. The slackening of the chains allows flaps in the cover to close. At the bottom of the track the arm 36 is depressed by contact of the roller 35 with a suitably shaped rail and the cover 42 is raised further to operate the bolt 50 through the lever 48 and link 52.
