An aqueous solution having an atomic/molar ratio of Na: K: cyanurate from 0À5 : 2 : 1 to 3À0 : 1 : 1 is prepared by reacting cyanuric acid with an aqueous mixture of potassium hydroxide and a sodium compound selected from sodium hydroxide, sodium oxide and sodium carbonate in proportions suitable to provide the said solution. A sodium potassium cyanurate compound or mixture of such compounds having an Na: K: cyanuric acid molar ratio in the range of from 1 : 2 : 1 to 2 : 1 : 1 may be obtained by evaporating the solvent from the abovementioned solution. The aqueous solution above is used for preparing [(monotrichloro)-tetra- (monopotassium dichloro)] pentaisocyanurate (I) and (monotrichloro) (monopotassium dichloro) di-isocyanurate (II) where n=4 for compound (I) and n=1 for compound (II) or mixture of these compounds by subjecting the said aqueous solution to treatment with chlorine at a pH of 2À1-6À0 and a temperature of from 0-50‹ C. The aqueous solution and the chlorine may be introduced into a slurry of a potassium containing chloro-isocyanurate complex compound as specified above or mixture of these in a reaction zone at a rate sufficient to maintain the desired pH. Slurry may be continuously removed from the reaction zone to maintain the volume of slurry in the reaction zone substantially constant. The preferred pH for compound (I) is 4À3 to 6À0 and for compound (II) is 2À1-3À4, the range 3À5 to 4.2 producing a mixture of the two. Preferably, the atomic/ molar ratio of Na: K: cyanurate in the solution is from 1À5 : 1À4 : to 2À25 : 1 : 1 and the temp. is maintained at 25-35‹ C.

Title: Improvements in or relating to Drying Machines
Inventor: ARCHER RICHARD JOHN
IPC: F26B5/04
Filed: 1965-10-21
Abstract: 1,169,533. Steam heated drying machines. E. W. HUDSON Ltd. 20 Oct., 1966 [21 Oct., 1965], No. 44650/65. Heading F4U. The heating chamber of a platen of a leather drying machine is, during drying, connected to suction means and to a source of saturated steam, and the supply of steam is regulated so as to maintain the pressure in the heating chamber substantially at that value at which the boiling point of water is equal to the required drying temperature. In the illustrated embodiment, the steam supply is controlled in accordance with the temperature of the heating chamber to maintain that temperature constant, and it is stated that, since both saturated steam and condensate are present in the chamber, the required constant pressure will be maintained. As illustrated, the platen chamber 104 is connected to the source of saturated steam through a valve 114 which is controlled through an air line by a unit 118 operating in response to platen temperature sensed at 119. The air line includes a valve 115 which interrupts control by the unit 118 and closes the steam valve 114 if platen pressure sensed by a pressure switch 120 exceeds a safety pressure. The platen is connected to vacuum by two parallel lines, one of which includes a valve 105 and the other of which includes a valve 113 and a flow restricting orifice 112. A hood 106 which covers leather stretched over the platen is connected through a valve 107 to vacuum to lower the pressure on the leather during drying and thereby aid evaporation of moisture from the leather. Flood valves 116 and 117 are provided to enable the platen and hood to be connected to atmosphere. At the beginning of a drying operation, a timer 110, acting through a valve 109 and a relay RA/2, closes the flood valves 116 and 117 and opens the vacuum connection valves 105 and 107. The platen 104 is pumped down until a pressure switch 121 senses a predetermined platen pressure, when the switch 121 acting via a contact RB2 and a relay RB/4, closes the vale 105 and opens the valve 113 so that the platen is connected to vacuum through the restricted line. Since the platen pressure will then be below the safety pressure at which the switch 120 is set, the valve 115 will be opened to allow the supply of steam to the platen under the control of the unit 118. At the end of the drying operation, the timer 110 de-energizes the relays so that the flood valves are opened and the steam and vacuum valves are closed.

Abstract: 1,088,341. Data transmission systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 20, 1964 [Nov. 21, 1963], No. 47315/64. Heading H4P. An exchange for a digital data system comprises a main store having a storage cell for each incoming and outgoing line, the lines and the cells being scanned in sequence so that data is transferred between the cells and the lines on a bit-by-bit basis. In accordance with routing instructions groups of bits (characters) are transferred from cells corresponding to incoming lines to those corresponding to outgoing lines via auxiliary storage bins and thence to the output lines on a bit-by-bit basis. The lines may carry start-stop data, or synchronous data accompanied by sync. signals, and the data may be at various bit rates. The lines are scanned several times per bit. When the scanning unit scans a given line, a word from the corresponding cells in the main store is passed to a register. In the case of start-stop data this word includes a bit indicating the previous status of that line, i.e. start indicating that a character is being received or stop. If the status bit is a stop bit it is compared with the bit currently on the line being scanned. If they are equal the word is returned to the store, but if unequal, indicating the start of a character, the status bit is reversed, the time of occurrence t is noted and a time indication t + 1À5T stored in the register (T is the bit duration). The content of the register is then returned to store. The next time the line is scanned the status bit is a start bit. The word read from the store is returned to it unless the time of scanning is t + 1À5 T, i.e. the middle of the first data bit, in which case the time indication in the register is incremented by T and the bit state of the line read in to the register. The register content returns to store. When the cycle has repeated often enough for the register to be filled by a received character the character is passed to a bin selected on detection of the start of message sequence by a processor associated with the exchange. On detection of the end of message sequence the complete message in the bin is processed and assigned to an output line bin in accordance with routing instructions. When the output line is scanned, the message is read out to it via the register in an analogous manner. Reception and transmission of synchronous signals is similar but must take account of the acommpanying sync. signals for detection of bits on a line. The system treats the synchronous data in blocks of length dependent on the capacity of the register.
