Title: Method of applying colour to venetian blind ladder-tape
IPC: D06B1/10
Filed: 1947-07-30
Abstract: In a process of applying colour to a Venetian blind ladder tape having two main tapes 11, 12, Fig. 6, connected by ladder rungs <PICT:0643873/IV (c)/1> <PICT:0643873/IV (c)/2> <PICT:0643873/IV (c)/3> 13, the tape is moved past a coating position and travelling mask means are interposed between the edges of the two main tapes. The edges of the upper tape 12, Figs. 1 and 2, are engaged by lifter flanges 16 and 17 of a guide member 18 to permit paper shield tapes 21 and 22 to be fed downwardly around pins or rollers 23 and 24, between the edge portions of the main tapes into guides 25 and 26 of the member 18 so that the ladder tape leaves the member 18 with the masks inserted between the edges of the main tapes 11 and 12.  The tape and masks pass between idler rolls 28 and 29 and between a colouring roll 30 and back-up roll 31.  The upper tape 12 may also be coloured by a second and similar but inverted coating apparatus, or by twisting the tape through 180 degrees and passing it through a similar apparatus.  The masking tapes 21 and 22 may be dispensed with after use, or paper tapes in the form of endless bands or aprons may be used.  The colour may be sprayed upon the tape instead of being applied by rollers.  The Specification as open to inspection under Sect. 91 comprises also a process of colouring a Venetian blind tape having an upper main tape somewhat narrower than the lower main tape and wherein a single masking shield extends enitrely across and beyond the upper tape, the colour being applied by printing rollers. This subject-matter does not appear in the Specification as accepted.

Title: Process for the preparation of pentaerythritol dihalogenohydrin monosulphurous acid esters
IPC: C07D327/10
Filed: 1952-08-22
Abstract: The invention relates to pentaerythritol dibromohydrin mono sulphurous acid ester and the preparation of pentaerythritol dihalohydrin monosulphurous acid esters by reacting a pentaerythritol dihalohydrin with thionyl chloride.  Reaction occurs on mere mixing; if desired it may be completed by heating up to about 100 DEG  C.  An inert solvent may be present.  In examples (1) pentaerythritol dichlorhydrin is added portionwise to cooled thionyl chloride and the mixture is then heated until evolution of hydrogen chloride ceases; the product is isolated by distillation or by water washing followed by crystallization from alcohol; (2) thionyl chloride is slowly added to a benzene solution of the dichlorhydrin and the monosulphurous ester recovered by distilling off the benzene; (3) pentaerythritol dibromhydrin is converted into its mono sulphurous ester as in (1). On treatment of the dichloro compound with alkaline reagents, 2 : 6-dioxaspiro-3 : 3-heptane, other compounds containing one or two oxa-cyclobutane rings and resins may be produced.  The dibromo and dichlor hydrins may be prepared by reacting pentaerythritol with hydrogen bromide or chloride.  Specification 729,459 is referred to.

Title: Improvements in or relating to the manufacture of cotton fabrics
IPC: D06C29/00
Filed: 1922-08-02
Abstract: 197,902. Zust, K. May 18, 1922, [Con- @ntion date]. Processes, compound.-A suede finish is produced on cotton fabrics such as calico, serge, or drill, by distensioning and pressing or calendering the fabric so that the whole of the warp and weft threads are on a level with their parts lying on the surface of the fabric as shown in Fig. 3, and then raising, grinding, or carding one or both surfaces of the fabric. The distensioning of the fabric is effected by treatment with a mercerizing-agent such as sulphuric acid, alkali, &c., the fabric being stretched if desired during this treatment. In some cases the fabric is calendered and subjected to a preliminary raising treatment before being mercerized, calendered, and finally raised. The mercerization allows the intersticial spaces 3 to be reduced to a minimum when the fabric is calendered or pressed, and causes the warp and. weft threads 1, 2 to lie more closely together.
