Title: 1, 3-di-(ªÏ-hydroxyalkyl)-ureas
Inventor: MCKAY ARTHUR FERGUSON
IPC: C08G18/38
Filed: 1956-10-16
Abstract: Linear polyurea-polyesters of the general formula HO[(CH2)nNHCONH(CH2)nOCORCOO]xH where n is 5 to 18 and R is a divalent hydrocarbon radical are prepared by reacting substantially equimolecular proportions of a compound HO(CH2)nNHCONH(CH2)nOH and a compound HOOC-R-COOH in the presence of an esterification catalyst, preferably polyphosphoric acid.  Preferred dicarboxylic acids are adipic, azelaic, sebacic and terephthalic acids.  The dicarboxylic acid may also be a compound HOOC(CH2)mNHCONH(CH2)mCOOH in which m is 2 to 17.  The hydroxyalkyl ureas may also be reacted with diisocyanates, e.g. hexamethylene- or toluene-diisocyanate to yield polyurea-polyurethanes.  In examples, adipic acid is reacted with hydroxyalkyl ureas in which n is 6 and 7.  Specifications 801,894, [Group IV (b)], and 804,299 are referred to.ALSO:The invention comprises compounds of the general formula HO HO(CH2)nNHCONH(CH2)nOH, where n is 5 to 18.  The compounds with n 5 to 8 are prepared by reacting a 1,3-bis (o -hydroxyalkyl)-thiourea in an alcoholic alkaline solution with hydrogen peroxide, filtering off the precipitated salt, and recovering the product from the filtrate by evaporation to dryness or by the addition of water.  The compounds of the invention in which n is 9 to 18 may be prepared by the method of Kjaer et al., Acta Chem. Scand., 7, 518 (1953).  In examples, compounds are prepared in which n is 5, 6, 7 and 11.  The compounds may be polymerized with dibasic acids (see Group IV (a)). Specifications 801,894 and 804,299 are referred to.

Title: Improvements in or relating to the recording and transmission of electric televisionsignals
IPC: H04N5/783
Filed: 1952-12-12
Abstract: 732,579. Recording television. TELEFONBAU UND NORMALZEIT GES. Dec. 12, 1952 [Dec. 22, 1951], No. 31531/52. Class 40 (3). In an arrangement for recording television signals, the signals are stored temporarily on, for example, an iconoscope screen and are recreated at a substantially lower speed by means such as a plurality of scanning beams which scan different respective parts of the stored signal and each control a magnetic recording head arranged for co-operation with a movable magnetizable tape. A television signal of 30 cycles to 6 megacycles developed in a television camera 11, Fig. 1, is applied by a high-pass filter 16 to an electronic converting device of the kind described in Specification 488,605 wherein the signal passed (60 Kc/s.-6 Mc/s.) is converted to 99 signals each of the same time duration as the original signal. The 99 outputs together with the 0-60 Kc/s. band passed by low-pass filter 14 are applied via amplifiers 15 to a hundred magnetic recording heads 13 for recording on magnetic element 19. The recorded signals are reproduced and the original television signal is reconstituted in a converting device also described in Specification 488,605. The arrangement provides facilities for future storage, slow-motion reproduction, and for the combination of two stored pictures. Control impulses included with the original transmission are also magnetically recorded and may be used for synchronizing the electronic conversion apparatus. A reference is also made to multistage conversion when the necessary number of narrow bands is high.
