Title: Improvements in or relating to the treatment of textile materials
IPC: D06M13/188
Filed: 1934-04-11
Abstract: <FORM:0436463/IV/1> An anti-crease treatment for fabrics comprises treating the fabric in open width whilst substantially tensionless with an aqueous liquor above 90 DEG  C. for less than 10 minutes, preferably 2--5 mins. at 97--100 DEG  C.  The aqueous liquor is water or dilute soap or like solution.  The treatment, which is preferably effected continuously by passing the fabric through the liquor, may also be used to develop cr<\>zepe effects in fabrics containing cr<\>zepe threads.  A suitable apparatus comprises feed rollers 4, a paddle winch 7 which submerges the fabric, and nip rollers 5, the vat is provided with heating pipes 2.  The submerging paddle may be dispensed with by disposing the feed rollers at or below the surface of the liquor.  In an example, a cellulose acetate fabric having cr<\>zepe weft threads is passed through a bath at 99 DEG  C. containing 5 gms. of soap per litre so that the fabric is immersed for 3 mins.  The liquor may contain any suitable wetting agent, e.g. sulphonated soaps, saponin, alkyl aralkyl or hydro-aryl substituted aromatic sulphonic acids.  Cr<\>zepe fabrics produced according to the invention may be directly dyed in rope or other folded form since the treatment provides adequate wetting out and eliminates the tendency of the fabric to crease on a winch machine.  Specifications 437,019, [Group IX], 437,943; 448,588, 438,589, 438,590, 438,591, and 438,729, [all in Group IX], are referred to.

Patent GB-855487-A (GB)
Title: Chlormethyl derivatives of alkyl-benzenes
IPC: C07C17/32
Filed: 1959-04-02
Abstract: Bis-(chlormethyl) derivatives of monoalkylor dialkyl-benzenes are produced by reacting the appropriate alkyl benzene with formaldehyde (paraformaldehyde or trioxymethylene), zinc chloride and hydrochloric acid, the reaction being carried out in the presence of an inert organic diluent, such as an aliphatic or alicyclic hydrocarbon or a chlorinated derivative thereof. Specified diluents are: carbon tetrachloride, chloroform, methylene dichloride, sym-tetrachloroethane, and cyclohexane. Examples 1 and 2 relate to the preparation of 2,4-bis-(chlormethyl) -toluene by adding toluene to a mixture of trioxymethylene, zinc chloride, carbon tetrachloride and hydrogen chloride, which had been heated at 60 DEG C. to bring about depolymerization of all the trioxymethylene.  The organic components of the reaction-products are separated by standard methods, and are submitted to distillation to remove the solvent and the unreacted toluene.  The mixture is then submitted to fractional distillation under reduced pressure, when monochlormethyltoluene distils over first, and is followed by 2,4-bis-(chlormethyl) toluene. The latter is purified by crystallisation from petroleum ether, n-hexane or n-pentane. Example 1 also describes the chlormethylation of the byproduct, viz. monochlormethyltoluene, to give further amounts of 2,4-bis-(chlormethyl) toluene.  Example 3 describes the preparation of 2,5-bis-(chlormethyl)-p-xylene by the chlormethylation of p-xylene using carbon tetrachloride as diluent.

Title: Improvements in machines for setting or driving rivets and the like
IPC: B21J15/10
Filed: 1940-07-15
Abstract: 540,345. Riveting. BAXTERS (BOLTS, SCREWS & RIVETS), Ltd., and DENT, W. C. July 15, 1940, No. 11698. [Class 83 (iv)] In a machine for setting or driving rivets or the like in which rivets are fed in succession to a holder 16 for operation by the tool 5, the holder is lowered by the operator to insert a rivet 17 within holes in the work 7 which is visibly located. The jaws of the holder are, in the starting position, slightly separated by a cone surface 32, Fig. 7, engaging arms 24, connected by a spring 25 and mounted on rotary shafts 19 which carry the arms 18 on which the jaws 16 are fixed. When the pedal is operated a cable 36, Fig. 3, connected thereto, pulls a slide 37 and, unless the resistance is great enough to swing a guideway 41 against the action of a spring 42, also pulls a slide 40 and a cable 46 which turns a lever 33, Fig. 4, and lowers the slide 27 carrying the holder 16 against the action of a spring. As this starts downwards the arms 24 leave the cone 32 and the jaws grip the rivet which is thus inserted in the work. The lever 33 also acts, through a link 48, lever 49, pawl 50, and lever 51, to press a locking slide 59 into a recess 60 of the lowered slide 27 and pull a cable 52 attached to a slide 53, Fig. 9, and thus release a one revolution clutch 57 and start the rotation of a shaft 14. This, operating through an eccentric 13 and a toggle 8, 9 commences to lower the tool 5, moves an abutment 71 of a cam 72 from the support 69 of the guideway 38 of the slide 37, so that the pedal can no longer pull the cord 46, and holds the lever 33 by a cam 67 when a retaining pawl 64 is tripped by a plunger 66 on the toggle. The cam 67 is shaped to press the holder 16 more firmly on the work and, as the tool approaches the rivet, the cone 32 engages the arms 24 and opens the holder to release the rivet which is then set against the anvil 6 by the tool 5. The tool and holder then commence to return to their original positions. Meanwhile a step 77 in the cam 72 causes the lever 69 to fall, or be moved by a spring, further to the right and thus, by means of a lever 78, rod 79, lever 80, Fig. 9, and slide 75, transfer a rivet from a shoot 15 to 15a Here it is held by a spring-returned slide 85 if this has remained in the left-hand position to which it was pulled by a cord 84, slide 55 and lever 54 operated by the movement of the slide 53 to start the machine. If however the slide 53 has returned to the right, to stop the machine after one revolution, the rivet falls to the lower end of the shoot 15a. When the tool 5 has withdrawn sufficiently, the rivet falls into the holder the jaws of which open slightly as previously described. Specifications 539,694, [Group XXIV], and 540,348 are referred to.
