Patent GB-940671-A (GB)
Title: Salts of organic sulpho-sulphinic acids, their preparation, and also the preparationof salts of organic disulphonic acids
IPC: C07C313/00
Filed: 1960-02-26
Abstract: The invention comprises salts of 1,2- or 2,3sulpho sulphinic acids of the general formula Me SO3 CHR1-CH(R2) SO2 Me in which R1 and R2 represent hydrogen or alkyl, hydroxy alkyl or an ether of hydroxy alkyl, or of the general formula Me SO3 C(R1)=CH(R2) SO2 Me in which R1 and R2 represent hydrogen or hydroxy alkyl, and Me represents a monovalent cation.  The salts are prepared by reacting the corresponding unsaturated organic compounds R1CH=CHR2 or R1C­CR2 with an acid solution of an inorganic or organic acid sulphite in intimate contact with oxygen or a gas containing oxygen, there being used at least 2 moles of the sulphite per mole of the unsaturated compound. The acid sulphite is preferably used free from neutral sulphite and in sufficient excess to compensate for that which becomes oxidised to sulphate.  The reaction may be effected in aqueous or organic solution at, for example, -10 DEG  to 100 DEG C.  The sulpho-sulphinate formed also comprises some corresponding disulphonate especially when the reaction is carried out in the presence of copper salts as catalysts.  The sulphosulphinates themselves may be subsequently oxidised to the disulphonates for example, by autoxidation or with hydrogen peroxide.  Examples describe the conversion of (1) alkyl alcohol to the potassium di-salt of 1-hydroxy propane 2-sulphinic 3-sulphonic acid and some potassium 1-hydroxypropane 2:3-disulphonate which are separated; (3) monoglycol ether of alkyl alcohol to the salt HOC2H4OCH2 CH(SO2K) CH2SO3K; (4) butene (2)-diol-1,4 to HOCH2CH(SO2K)CH(SO3K).CH2OH; (5) ethylene to the potassium disalt of ethane-1 sulphinic-2-sulphonic acid; (6) propylene to the potassium di salt of propane-1-sulpho-2-sulphinic acid; (7) propargyl alcohol to the potassium disalt of 1-hydroxy-propene-(2) sulphinic -3-sulphonic acid and butine-(2)-1:4-diol to the potassium di-salt of 1:4-dihydroxy butene-(2)2-sulphinic 3-sulphonic acid.  In Example (8) ethylene is reacted with triethyl ammonium hydrogen sulphite yielding the triethyl ammonium ethane sulpho-sulphinate.  All these sulpho sulphinates are oxidised to the disulphonates using aqueous HO2.

Abstract: 1,074,417. Data transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 17, 1966 [April 27, 1965], No. 6938/66. Heading H4P. In a. data transmission system in which n receiving stations are selected to receive a common text, the last station selected is judged to be that most likely to have most errors in the received data. It is arranged that only that station returns error-indicating signals to the transmitter. In the system described a line is seized by a keyboard to ready all the receivers connected to it and a " start of address " signal is transmitted. For each required station in turn there is sent an address and an interrogation signal. If the called receiver is in a condition to receive it returns a ready/not ready signal to the transmitter, where it is printed. When all the stations are selected an " end of address " signal is sent. Data is now transmitted in blocks, with horizontal and vertical parity checks. An " end of block " signal after each block causes the last station which was selected to return a signal, which is recorded at the transmitter, indicating whether or not error was detected. The data transmitted is also recorded, with the return signals, at the transmitter. Finally an " end of text " signal reverts the system to quiescent.

Abstract: 1431521 Filter DONALDSON CO INC 19 Feb 1974 [26 Feb 1973] 7440/74 Heading BID [Also in Division F2] An hydraulic oil filter comprises a cup-like housing 10 clamped to ahead 17 by bolt 13, the upper edge of housing 10 being turned in to form a frusto-conical sealing portion 10b (Fig. 3) which co-operates with flange 17c of the head to form a triangular section space 9 enclosing rubber sealing ring 18. As pressure within the housing rises the housing tends to expand against flange 17c, and the oil forces ring 18 downward, improving the seal. The seal is also effective under reduced pressure, the ring being then drawn into space 9b. The housing encloses an outward-flow, annular, pleated filter element 20 carrying a by-pass valve member 22. Rising differential pressure pushes element 20 and member 22 downwards against spring 15 until upper edge 22c clears edge 17f to by-pass the element 20. Extensions 35 of the valve member are coloured green and normally visible through side windows (not shown) in head 17. Extensions 35 are then located in pockets 38 which trap air against the windows. When valve 22 is depressed, the red interiors of pockets 38 become visible to indicate this. The member 22 may be modified to indicate the need to remove and clean element 20 wtihout allowing by-passing. The filter and valve may be modified for inward-flow filtration.
