Patent GB-1391590-A (GB)
Title: Systems for enciphering and deciphering teleprinter signals
IPC: H04L9/36
Filed: 1964-01-13
Abstract: 1391590 Code telegraphy SIEMENS AG 13 Jan 1964 [14 Jan 1963] 1510/64 Heading H4P In a system for enciphering and deciphering teleprinter signals in the international 5- element code, which signals are to be transmitted from a transmitting station to a receiving station, the characters are enciphered by mixing with cipher characters, one selected character, e.g. D, F, G or H, which is used in the plainlanguage form in the latter form only being replaced before mixing by the "letter-change" character, this "letter-change" character being enciphered, and the enciphered characters are deciphered by mixing with the cipher characters, the "letter-change" character apearing in plain-language form during deciphering, and a memory containing the last received type change character, i.e. "letter-change" or "digitchange", is consulted and when this last received type change character is "letter-change", the "letter-change" character appearing in plainlanguage form is replaced by the selected character. This enables the selected character to be made available for other purposes, particularly for arranging the system to be such that neither the combination "D/who are you?" nor the combination 32 is transmitted in the enciphered message. Combination 32 in the enciphered message may be replaced by combination D mixed with the cipher character that produced the enciphered combination 32 and combination "D/who are you?" replaced by combination 32 mixed with the cipher character that produced the enciphered combination "D/who are you?". Means are provided to ensure that replacement of the selected plain-language character by the "letter-change" character is not effected during enciphering if the plain language character and the cipher character are found to be indentical, and in a corresponding manner, on deciphering, the appearance of the selected character in plainlanguage form does not result in any special operation connected with the avoidance of "D/who are you?" and combination 32, in the case in which the cipher character and the deciphered character are identical. Also, replacement of the selected plain-language character by the "letter-change" character is omitted when the cipher character is the combination 32; moreover, on deciphering, the appearance of the selected character in plain-language form does not result in the subsequent replacement of the enciphered character by the combination 32 in the circumstance in which the cipher character is the combination 32 and the deciphered character is the selected plain-language character.

Title: Refining of solvent-extracted vegetable oils
IPC: C11B3/06
Filed: 1950-01-20
Abstract: A process for refining and decolorizing solvent-extracted vegetable oils by agitating with aqueous sodium hydroxide is carried out in the presence of at least one non-ionic ether of a polyhydric alcohol containing two to three hydroxy groups and from two to eight carbon atoms or a non-ionic derivative of such of said ethers as contain an unreacted hydroxyl group, such compounds being liquid at about 80 DEG F.  The ether may be a polyglycol containing at least two glycol units, such as polypropylene glycol having a molecular weight of about 400, and may have one or both of the hydroxyl groups etherified by alkyl groups of from 1 to 18 carbon atoms or substituted by carboxylic, phenolic, amino or mercapto groups.  The addition of the non-ionic ethers improves the colour removal and permits reduction in the quantity of alkali used and in the time of treatment.  Examples are given showing the colour reduction obtained when extracted cottonseed or soya bean oils containing about 40 per cent oil and 60 per cent hexane are agitated with aqueous alkali and polypropylene glycol of about 400 molecular weight at about 130 DEG F, and with a number of other ethers and ether esters of the polyglycol type.

Abstract: 1,008,967. Charging and discharging batteries; systems with selectable sources of supply. SPERRY RAND CORPORATION. Jan. 17, 1963 [Jan. 29, 1962], No. 2093/63. Heading H2H. The D.C. driving motor MR of a shaver apparatus SA is supplied from a transformer/ rectifier power pack PP or from a batter B rechargeable by the pack PP, selection of any one of these three operations being controlled by a single-pole two-way switch KS having an open mid-position and having its two stationary contacts interconnected by a resistor RB. Another resistor RA is connected in series with the primary winding TRP of the transformer TR and in parallel with a circuit defined by the mid-point of the transformer secondary winding TRS and the moving contact of the switch KS. With this contact in position I and shaver SA unplugged from the power pack PP, the motor MR is supplied from the battery B. Should members SA, PP be inadvertently connected in this contact position, the resistors RA, RB respectively reduce the output of pack PP and the current supplied therefrom to members B, MR, thus preventing mal-operation. With the switch contact in position II and members SA, PP connected together, battery B is charged from the pack PP at a current limited by the resistor RB, the resistor RA serving to reduce the output of the pack PP and the current in winding TRP and to reduce the current through the motor MR to a negligible amount. With the switch contact in position III resistor RA is short circuited and the (increased) output of pack PP drives the motor MR, the resistor RB limiting the current through the battery B. Members SA, PP may have a non-symmetrical plug and socket to prevent incorrect connection. For a motor requiring less power, the resistor RA is omitted together with its connections to the switch KS and the mid-point of the winding TRS, Fig. 1 (not shown).
