Patent GB-1391441-A (GB)
Title: Enciphering and deciphering systems for teleprinter signals
IPC: H04L9/18
Filed: 1963-08-20
Abstract: 1391441 Data transmission; ciphering SIEMENS AG 20 Aug 1963 [21 Aug 1962] 32818/63 Heading H4P In a system for enciphering and deciphering teleprinter signals in which unciphered characters are enciphered by mixing with a cipher character, when the first of two particular characters which it is not desired to transmit, e.g. 32 (00000 in the International Five Element Alphabet No. 2), occurs as an enciphered character at the transmitting station, before it is transmitted, a first specific character, e.g. the "line shift" character ZL (01000), not employed as an unciphered character is substituted for the first particula character and mixed with the cipher character to form a substitute enciphered character; and when the second of the two particular characters, e.g. the "who are you?" character D (10010) occurs as an enciphered character at the transmitting station, before it is transmitted, a second specific character, e.g. 32 (00000), not employed as an unciphered character is substituted for the second particular character and mixed with the cipher character to form a substitute enciphered character. One example of the above is illustrated in the following table: Great significance should not be attached to the enciphered signal being identical to the original plain-language signal. Using electronic means three mixing operations finishing consecutively in close succession and can be completed during the time of transmission of the start element of the enciphered signal. To permit transmission of any desired information without employing the two specific characters in the plain-language signals, a single teleprinter signal must be employed to represent two concurrent functions. By combining the functions of "carriage return" and "line shift" under the character normally used for the "carriage return" function, the "line shift" character ZL (01000) can be made available. In order to prevent the occurence of an undesirably large line spacing, a unit may be provided in the receiving teleprinter station which effects "line shift" only on reception of the first of these successively arriving characters, suppressing this function on immediately following occasions. Alternatively, it is possible with each appearance of the "carriage return"/"line shift" combination to effect "line shift" by half a normal step; thus, after the said character has been received twice, the normal line spacing is obtained. It it is desired to avoid a third mixing process, then one possibility is to use "signal identification". Since the two special cases are characterized by the simultaneous occurrence of either D (plain-language signal) and Bu (cipher signal) or of J (plain-language signal and H (cipher signal), a special circuit can be used to immediately produce the enciphered signal ZL or J. In this case, the second mixing process is also rendered unnecessary. If this signal identification is limited to the appropriate signals at the second mixing stage, then only the third mixing process is omitted.

Patent GB-322620-A (GB)
Title: Improvements in or relating to method and apparatus for producing sheet glass
IPC: C03B13/04
Filed: 1928-11-13
Abstract: 322,620. White, A. E., (Mississippi Glass Co.). Nov. 13, 1928. Rolling.-A method of making sheet-glass consists in flowing molten glass from a tank furnace to the pass between a pair of rollers in a thin stream of substantially the same width as the sheet to be formed, and in cooling one surface of the molten glass before it reaches the pass so as to stiffen the surface. Reinforcing wire may be fed into the molten glass, after the surface has been cooled, so that the stiffened surface supports the wire. The glass flows in a thin stream 1 over a wide spout 3 attached to a tank furnace 2, and it falls on to a watercooled roller 4 by which its lower surface is cooled. The glass is carried into the pass between the roller 4 and a second roller 5, and is formed into a continuous strip 30. A ball of glass, 6, is permitted to accumulate against the roller 5 to ensure a sufficient supply above the pass. Side strips 8 may be provided to keep the glass in position. As the stream 1 passes over the surface of the roller 4, a sheet 7 of wire fabric may be fed into the top surface of the glass as it passes into the ball 6. The wire is fed from a roll 7<1> downwards between watercooled shields 9, 10, so that it is prevented from oxidizing before it passes into the sheet and retains its bright polish. The sheet, after formation, passes over watercooled aprons 16, 19 into a leer and may be passed between rolls 17, 18 to impress a figured design on the surface. Watercooled shields 21, 22 may be provided to protect the rolls 5, 18 from the heat given out by the glass.

Title: Improvements in and relating to binders for sheets of paper and the like
IPC: B42F13/30
Filed: 1935-11-30
Abstract: 449,445. Loose-leaf binders. BOLTON, F. B., Griffiths House, Queen Street, Brisbane, Australia. Nov. 30, 1935, No. 33261. Convention date, Dec. 3, 1934. [Class 146 (i)] In a loose-leaf binder of the type in which telescoping pins and sockets are carried by two L-shaped back members having a limited sliding movement towards or away from each other, the pins enter non-telescopic tubular sockets, one set of such pins and sockets being shorter than the other so that, when the halves of the binder are moved apart to the limit of their travel, the pins of one set of posts are separated by a short distance from their sockets, while the pins of the other set remain engaged with their sockets. Telescoping pins and sockets G, G<1>, H, H<1> are mounted on the shorter legs of the L-shaped back-plates C, D, to which are hinged at B the covers A. Guidechannels E on the plate C engage the ends of the plate D, and the outward sliding movement of the plates is limited by spring catches F engaging stops E<1> on the channels E. Sheets of paper can then be inserted or removed, the papers being perforated at N to engage the separated posts H, and slotted at O to engage the telescoped posts G. The plates and posts can be separated altogether by depressing a spring wire F<1>, and thereby disengaging the catches F from the stops E<1>. Certain of the pins may be long enough to project through the opposite plate when the binder is closed so that they can be engaged by locking means. The sockets d are preferably of larger diameter than the sockets H. Easels J are hinged to the covers A, and supported by struts K engaging in holes J. The easels and struts when folded flat are retained by pivoted catches L. The binder mechanism may be independent of a cover.
