Patent GB-1598468-A (GB)
Title: Process for producing insulating sheets from finely dispersed material
IPC: C04B30/00
Filed: 1978-03-21
Abstract: The invention relates to a process for producing insulating panels from finely disperse material, consisting of a mixture of pyrogenic silica and an opacity agent such as TiO2, which is pressed and enveloped. Such insulating panels of microporous silica are, because of their specifically high heat conduction resistance and their resistance to very high and low temperatures, used increasingly in technical apparatus, especially if a high insulation effect against heat and cold is demanded with little space available. To obtain a homogeneous heat insulation panel, the pressing step should be carried out according to the invention in a heated mould or between at least two press plates, at least one of which is heated. In addition, the finely disperse material can be pressed under a pressure of from 5 to 10 kp/cm<2> and the envelope can be heated to about 70 DEG C to 350 DEG C during pressing.

Patent GB-730923-A (GB)
Title: Process for the preparation of a new aldehyde derivative
Filed: 1953-05-04
Abstract: The invention comprises as new compounds N-hydroxymethyl-methionine and its sodium, potassium, barium and calcium salts.  Such compounds are obtained by reacting methionine with formaldehyde in alkaline solution at a pH value greater than 7.  When the product is obtained as a salt, the latter may be converted to N - hydroxymethyl - methionine itself.  In examples: (1) methionine and formaldehyde are reacted in the presence of aqueous sodium hydroxide, and the solution obtained is treated with a cation-exchange resin and evaporated to dryness, and the product is redissolved and precipitated by adding acetone to give N-hydroxymethyl - methionine.  If sodium or potassium hydroxides are added to the reaction in equivalent amounts to the reactants, and the treatment with the cation-exchange resin is omitted the corresponding salts are obtained; (2) methionine and formaldehyde are reacted in aqueous baryta solution to give the barium salt of N-hydroxymethyl-methionine from which the free compound is liberated by the addition of sulphuric acid; (3) methionine and formaldehyde are reacted in the presence of aqueous calcium hydroxide to give the calcium salt of N-hydroxymethyl-methionine, from which the free compound is liberated by the passage of carbon dioxide.

Title: Improvements in or relating to looms for weaving carpets and like tufted pile fabrics
IPC: D03D39/02
Filed: 1930-04-22
Abstract: 352,573. Pile fabric looms. SOUTHWELL, Ltd., H. & M., The Friars, and HEAD, T. W.; 39, Whitburn Street, both in Bridgnorth, Shropshire. April 22, 1930, No. 12360. [Class 142 (ii).] In looms for weaving Axminster carpets &c. having tuft-yarn spool and tube carrier frames extending across the entire width of a wide fabric, as described for example in Specification 293,513, [Class 142 (ii), Looms, Kinds &c.], the frame is given additional support when in operative position by regulating arms 1 situated at intermediate.points between the usual transferring arms, not shown, which take successive tube frames 22 and spools from the carrier chains to transfer position and then return them to the chains. The arms 1 are supported independently of the transferring arms by a roller 17 on which they can pivot and also slide, and are acted upon by springs 10 and adjustable rollers 9 on arms 8 on a cam shaft 4, which is rocked by a lever 6 and link 7. One or more levers 11 for each arm 1 dependent from the shaft are connected to the arm by pin-and-slot arrangements and links 13 furnished with springs 15 adjusted by nuts 16. A tube frame is first moved downwards until the tube ends 29 pass into the fabric backing, next it is raised as shown and at this time the arms 1 are slid forwards so that adjustable fingers 20 pass through loops 21 on the tube frame. A slight depressing of the rollers 9 then causes the arms 1 to be slightly lifted whereby the tube frame 22 is regulated to cause an equal length of threads 27 to be left below the warp threads throughout the whole width of the fabric. These lengths are then bound in by weft previous to heating up and actuation of the looping devices 33. The tube frame 27 is then raised to cause equal lengths of threads to be drawn out before being severed by the knives 26, 34, the arms 1 having been slightly raised by coaction between swells 23 thereon and runners 24 on the knife-supporting block. Afterwards the arms 1 are withdrawn backwards from the tube frame 22, which is then replaced in its carrier frame by the transferring arms.
