Title: Improvements in or relating to advertising signs or the like
IPC: G09F19/14
Filed: 1934-08-23
Abstract: 443,229. Changing signs. THREE WAY SIGNS, Ltd., and SMITH, V. M. M., 84, Hatton Garden, London. Aug. 23, 1934, No. 24359. [Class 3 (i)] In advertising signs or the like of the type in which a plurality of displays are shown on a background and on one or more sides of upstanding ribs respectively, the particular display seen depending on the position of the observer, the display matter is printed &c. on the ribs before their erection in such a manner that demarcation lines which are inclined to the longitudinal axes of the ribs are seen as continuous lines from a given view point. Figs. 1 and 3 show how a serrated edge outline is imparted to letters " A " and " O " to give continuous straight or curved edges to the said letters when the ribs are turned up and the observation is made from a predetermined point. The printing &c. may be facilitated by providing coincident marks 14, 15 joined by lines 18 on each side of a sheet 10 to enable the printing &c. to be done before the lines 18 are cut through for bending up the ribs. Specification 1054 /13, [Class 3 (i)], is referred to.

Title: Improvements in or relating to the recording of sound
IPC: G11B17/02
Filed: 1925-10-01
Abstract: 263,550. Western Electric Co., Ltd., (Bell Telephone Laboratories. Inc.). Oct. 1, 1933. Drawings to Specification. Disc records.-A disc record giving a maximum time of reproduction is produced by recording only on that part of the record extending from the outer sound groove to a position at approximately one-half of the radius of the outer groove and driving at an angular velocity such that the linear speed of cutting of the innermost groove is the least at which a satisfactory groove can be cut in the blank material. A suitable cutting speed in revolutions per minute is given by dividing 60 times the minimum linear speed by # times the radius of the outer sound groove. The minimum linear speed when cutting the inner groove is suitably from 14 inches to 17 inches per second. and the record may suitably be cut when running at a rate of 30 to 60 revolutions per minute, the rate being determined by the diameter.

In a record changer, the pawl which unseats records from the step of the centre-post becomes locked when the last record has been dropped, whereby a control device for stopping the machine is rendered operative and is actuated, after the last record has been played, by the mechanism controlling the unseating of the records. In the embodiment described, a steadying plate 10 falls over the unseating pawl 8 when the last record drops, and locks it so that when the record has been played and a fresh automatic cycle commenced, a rod 19 which normally slides up the centre-post 4 under the influence of a bellcrank 17 and operates the pawl 8, becomes locked with the centre-post 4 which is thus moved bodily upward until an arm 7 thereon is brought into the path of a pin 20 on a cycling disc 16, whereby, by means not shown, the machine is stopped. The stopping occurs at the end of the cycle so that the machine is left in a condition ready for a fresh cycle.

Filed: 1928-08-27
Abstract: 296,986. Kaiser - Wilhelm - Institut f³r Eisenforschung. Sept. 10, 1927, [Convention date]. Waterproofing; proofing against bacteria; proofing materials; wood, treating with liquids.- Fibrous substances such as wood &c. are treated with molten metal or molten metal alloy which is forced into the fibrous substance so as to produce a metallic product with a fibrous structure. The wood or other substance is previously freed if necessary from non-fibrous substance by chemical extraction. The pressure and temperature at which the metal or alloy is forced or drawn into the wood &c. depend on the nature of the substances employed. The proportion of metal employed may vary; where wood is treated with a large quantity of metal, the product has a high electrical conductivity and specific gravity. is incapable of absorbing water, is not affected by bacteria or insects, and may be polished like metal. At the same time the fibrous structure and grain is retained. In an example, walnut is heated to 240‹ C., and immersed in molten tin. The impregnating chamber is subjected to a pressure of 50 atmospheres for several seconds, and the wood then taken out and cooled.

Title: Polyester compositions
IPC: C08G63/82
Filed: 1961-07-11
Abstract: The Specification discloses sulphonates of formulae <FORM:0982584/C2/1> where X, Y, A, A1, X1 and Y1 are each organic radicals free from ester-forming functional groups, Z, Z1 and Z11 are either -O-SO2- or -SO2-O-, n is 1 to 4 and m is 1 to 10.  They may be made of reacting a sulphonyl halide with an alcohol or a phenol in the presence of an alkali.  In examples, (1) diphenyl benzene-m-disulphonate is made by dissolving benzene-1,3-disulphonyl chloride and phenol in acetone and pouring in aqueous sodium hydroxide solution; (3) isopropylidene-p,p1-diphenylene di-p-sulphonate is similarly made from p-toluenesulphonyl chloride and 2,2-di-(p-phenyl)-propane.ALSO:Polyesters are given greater dyeability and a lesser tendency to pill by incorporating in them a compound containing at least one sulphonic ester group (-O-SO2-) but no ester-forming functional groups in such an amount that the total number of sulphonic ester groups is from 0.1 to 20% of the carboxylic ester groups in the polyester.  The incorporation may be effected before, during or after the reaction leading to the polymer.  If effected in the first two of these methods in those processes in which an aliphatic diol is a reactant, polyether links may be introduced into the polymer.  The compound incorporated may have the formula (X-Y-)n-Y, A-Z-(X1-Z-)m-A1 or A-Z-(X1-Z1-Y1-Z11-)m-A1 where X, Y, A, A1 and Y1 are organic radicals free from ester-forming functional groups, Z, Z1 and Z11 are each either-O-SO2-or -SO2-O-, n is 1 to 4 and m is 1-100. The sulphonic esters may contain substituent metal sulphonate groups. In the manufacture of the polymers, the usual catalysts, delustrants and stabilizers may be added.  In examples, the sulphonic esters were added at some stage to polymers prepared by reacting (a) dimethyl terephthalate and ethylene glycol; (b) dimethyl terephthalate and 1,4-dihydroxymethyl cyclohexane; (c) dimethyl terephthalate, dimethyl diphenyl methane : p,p1 - dicarboxylate and ethylene glycol; (d) terephthalic acid and ethylene glycol; (e) dimethyl terephthalate, ethylene glycol and methyl p-beta-hydroxyethoxy benzoate and ethylene glycol.  In a further example, hydroquinone diacetate is reacted with adipic acid in the presence of diphenyl benzene-m-disulphonate and the polymer added to a polymer prepared from dimethyl terephthalate and ethylene glycol.
