Patent GB-743922-A (GB)
Title: Phosphate plasticizers
IPC: C07F9/09
Filed: 1953-04-16
Abstract: A composition comprises a thermoplastic material, e.g. a derivative of cellulose, plasticized with a bis-dipropyl phosphate of an alkylene or mono-oxa-alkylene glycol, said glycol having 4 to 8 carbon atoms in the molecule (see Group IV (b)). The cellulose derivatives include cellulose esters such as cellulose nitrate cellulose acetate, cellulose propionate, cellulose butyrate, cellulose acetate-propionate and cellulose acetate butyrate as well as cellulose ethers such as ethyl cellulose and benzyl cellulose. Specified bis-dipropyl phosphates are those of 1,4 - butanediol, diethyleneglycol, 2,5 - hexanediol, and of dipropylene glycol.  In examples plastic grade cellulose acetate is mixed with diethylene glycol-bis-dipropyl phosphate and butanediol-1,4-bis dipropyl phosphate respectively and pressed discs of good fire-resistance are prepared by moulding each mixture at 200 DEG  C. for 15 minutes.ALSO:The invention comprises as new compounds bis-dipropyl phosphates of an alkylene or monooxa-alkylene glycol, said glycol having 4 to 8 carbon atoms in the molecule.  Specified compounds are the dipropyl phosphates of 1,4-butanediol, diethylene glycol and 2,5-hexanediol and of dipropylene glycol.  The products may be obtained by reacting 2 mols. of dipropyl chlorophosphate with one mol. of the glycol which may be tetramethylene; 3-oxa-1,5-pentylene; 3 - oxa - 1,5 - dimethyl - 1,5 - pentylene, hexamethylene; 2-ethyl hexamethylene; 2,2-diethyl trimethylene, or 5-oxa-1,7-heptylene, or diethylene glycol.  The reaction is preferably carried out in the presence of an acid acceptor and mutual solvent such as pyridine. Examples describe the production of diethylene glycol bis-dipropyl phosphate and butanediol - 1,4 - bis-dipropyl phosphate by reacting the corresponding glycol with dipropylchlorophosphate in the presence of pyridine.  The dipropyl chlorophosphate used is prepared by adding phosphorus trichloride gradually to n-propyl alcohol maintained at 8-11 DEG  C. and then chlorinating by introducing chlorine under reduced pressure at 8-10 DEG  C. until the reaction mixture turns yellow and a temperature drop is noted.  Residual HCl is then removed and the product is then distilled under reduced pressure to yield dipropyl-chlorophosphate.  The alkylene glycol phosphates are stated to be suitable as plasticizers for thermoplastic material particularly cellulose derivatives (see Group IV (a)).

Title: Improvements in and relating to printing mechanism for calculating machines
IPC: G06K15/04
Filed: 1935-04-05
Abstract: 454,857. Typewriters &c. BALDWIN, R. E., 123, Fairlands Avenue, Thornton Heath, Surrey. April 5, 1935, No. 10587. [Class 100 (iv)] Relay type - wheel and type bar actions.- Printing-mechanism for a calculating-machine comprises a swinging or reciprocating typecarrier, an associated control-member, and a single latch which is differentially movable by means of a plurality of control-stops to determine the position of the type-carrier relatively to the control-member. Preferably, the series of stops is employed for numerical-selection, and when one of the control-stops also is employed, the type-carrier moves relatively to the control-member and alphabetical selection is effected. The apparatus shown in the Figure is controlled by a twelve-hole card, the top two holes representing the letters A, B, the other holes representing numerals, and combinations of the A or B hole and a numeral hole representing the other letters. The apparatus comprises stops 11, 12 set by the A and B holes, stops 13 set by the numeral holes, and a retaining-stop 10 which normally engages a lug 9 on a swinging control-sector 6 having a latch 28 for engaging stepped shoulders 29, 30, 31 on a swinging type-sector 7. The stops 11, 12, 13 are provided with setting-means of the kind described in Specification 26896/13, [Class 100 (iv)]. A spring 38 for urging anti-clockwise the controlsector and type-sector is connected to a link 42 which is supported by a rock-arm 40 and is connected to the type-sector, the arrangement causing th'e spring to maintain an even pull. A spring 34, connecting the control-sector and type-sector, maintains the latch 28 in engagement with one of the shoulders 29, 30, 31. The latch normally engages the shoulder 29, and is differentially displaced by the stops 12, 11 to engage the shoulders 30, 31 respectively. For depressing the retaining-stop 10 when any of the stops 11, 12, 13 are raised, the latter stops are provided with pins 22 engaging a bar 21 which abuts on levers 17, 24 in connection with the retaining stop. When one of the stops 13 is raised, the control-sector is released, and swings with the type-sector until the lug 9 engages the raised stop, the selected numeral-type being thereby brought to the printing line. -If the stop 12 or 11 is raised, the latch is displaced, the type-sector swings until the shoulder 30 or 31 is caught by the latch, the control-sector swings with the type-sector until the lug 9 engages a stationary stop 37, and the A-type or B-type is brought to the printing line. If one of the stops 13 and the stop 11 or 12 are raised, the latch determines the position of the type-sector relatively to the control-sector, the stop 13 determines the position of the controlsector, and letter-types other than A and B are brought to the printing line. A restoring-bar 44 for the control-sector and type-sector is carried by arms 43 in connection with a rockarm 46.

Title: Improvements relating to colour television
Inventor: GARGINI ERIC JOHN
IPC: H04N11/14
Filed: 1957-04-01
Abstract: 863,604. Colour television. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 1, 1957, No. 10976/56. Class 40(3) Information relative to a coloured image is transmitted as two signals, one of which is a signal representative of the luminance of successive points of the image, and the second of which is a colour signal of which the phase represents the hue of corresponding points and the amplitude represents substantially the ratio of the intensity of the hue of said corresponding points to the total equienergy intensity thereof. Transmitting equipment for carrying out the invention, Fig. 1, is generally similar to that employed for producing N.T.S.C.-type signals except that a dividing stage 18 is included in the subcarrier channel and receives a equi-energy (brightness) controlling signal E E  = R + G + B from an 3 3 3 adding circuit 4a. The three 120 degrees phase modulations of the subcarrier then represent G/E E  B/E E  R/E E  so that the signal amplitude is independent of brightness. The luminance signal is made up of 0.59G + 0.30R + O.11B. The colour signals R, G and B are restricted in bandwidth (to 2mc in the example given) by filter 9 before application to the subcarrier modulators 11-13 and the brightness signal E E  fed to dividing circuit 18 is restricted similarly by filter 19. As an alternative to using 120 degrees phase modulation with R, G and B signals, 90 degrees phase modulation may be used with signals R-Y and B-Y. Prior to transmission the subcarrier is modified so as to limit the bandwidth of the hue information to 1.5 mc and that of the saturation information to 0.5 mc. This is effected by feeding the subcarrier firstly to an amplitude detector 20 which extracts the saturation information and passes it through a 0-0.5mc filter 22, and secondly to an amplitude limiter 21 which allows only the phase modulation due to hue information to pass to a 1.5mc bandpass filter 23. The band limited subcarrier is then remodulated by the band limited saturation signal in modulator 24. The final subcarrier signal may be combined with the brightness signal and modulated on a carrier for vestigial sideband transmission in the normal way. The subcarrier may be located either inside the luminance signal or outside it on either the main or vestigial side of the main carrier. The subcarrier frequency may be chosen to be either an odd integral multiple of half line frequency or an even multiple of half line frequency and reversed in phase after each two frames. The actual subcarrier may also be suppressed at the output of the transmitter. Specification 698,949 is referred to.

Title: A method of carrying on catalytic molecular association of organic compounds
IPC: B01J8/02
Filed: 1928-04-14
Abstract: 306,883. Selden Co., (Assignees of Jaeger, A. O.) Feb. 27, 1928, [Convention date]. Esters; aldehydes.-In a process for effecting the molecular association of organic compounds the reacting vapours are passed through heatexchanging elements at least partly embedded in a catalyst layer, the vapour being in indirect heat-exchanging relation with the catalyst; the flow is then reversed and the vapour passed in direct heat-exchanging relation with the catalyst and with the incoming gas; and finally the vapour passes after another reversal of flow through the catalyst layer. In the illustrated modification the vapours pass down through the tubes 9, up through the surrounding tubes 11, and down through the catalyst. In a modification the passages are in the form of concentricannuli instead of separate tubes. A portion of the gas may be admitted directly to the catalyst, e.g. by the pipe 14. A part or all of the reaction mixture may be recirculated through the converter either with or without previous extraction of a part or all of the reaction products or correction of its composition by additions through the pipe 51. A cooler 75 mav be inserted in the recirculation system. The heat-exchange tubes. may project through the catalyst layer into the gas space beyond it, or on the other band the catalyst maybe arranged in two or more layers. of which only the first is cooled by the heat exchangers. Loss of heat at the periphery of the converter may be compensated for by spacing the outer heat-exchangers further apart or by reducing the flow of gas through them by plugs 56. Temperature-equalizing means 55 may be embedded in the catalyst; they may be solid rods of metal &c. or tubes containing a liquid which may or may not boil at the reaction temperature. The Specification describes the application of the process to esterifications, condensations such as condensation of acetaldehyde to aldol or crotonaldehyde, and polymerizations. Specifications 283.887. 301,491. 301.799. 306,442, and 306,519. [all in Class 1 (i). Chemical processes &c.], are referred to.
