Title: Crystallisation systems
IPC: B01D9/00
Filed: 1979-07-02
Abstract: This invention provides a method and apparatus for the continuous crystallisation of dissolved solids from solution and in particular to the recovery of pickling solution by the continuous removal of contaminating salts. The solution is continuously fed through a crystallisation unit 14 where it is cooled so that the dissolved solids crystallise out and separate from the stripped solution under gravity, the flow of stripped solution out of the crystallisation unit changing in direction so that it moves in a counter flow to the flow of crystallised solid under the influence of gravity. The crystallisation unit 14 comprises a primary cooling column 13 whose upper end outlet leads to the upper end of secondary cooling column 15. The lower end of column 15 opens into settling tank 16 which has a lower outlet for removal of crystallised solids and an upper outlet for stripped solution. <IMAGE>

Patent GB-2032012-A (GB)
Title: Lubrication systems
IPC: B65G45/08
Filed: 1979-08-31
Abstract: A lubrication system is arranged to lubricate a fast-running chain mounted on a chain dredger drum. The system includes a pump (2), and a feed duct (3) coupled to the pump (2). Two lubricant dispensers (4 and 5) receive lubricant from the duct (3). Each dispenser (4, 5) is operable in response to the pressure of the lubricant reaching a predetermined value to discharge a discrete volume of lubricant to the chain. An electromagnetically operable valve (6) is located in the feed duct downstream of the coupling point for the lubricant dispensers (4 and 5). A switch when periodically tripped by a member moving with the chain energises the electromagnetic valve (6) to block the feed duct (3) to enable the pressure in said duct (3) to exceed said predetermined value and so cause the dispensers (4 and 5) to discharge lubricant onto the chain, The quantity of lubricant dispensed is thus related to the movement of the chain. <IMAGE>

Title: Transistor gating circuit
Inventor: DAVIES GRAHAM THOMAS
IPC: G11C11/403
Filed: 1981-06-30
Abstract: A gating circuit, for use with dynamic MOS circuitry such as dynamic random access memories (RAMs), which is such as to reduce capacitor leakage back to the input due to negative undershoot effects. Two MOS transistors (21, 22) are arranged in series between the input (20) and a storage capacitor (24). The transistors (21, 22) are conductive for the duration of the "high" value of a clock pulse ( phi 1) to permit charging of the capacitor. Between the occurrence of the "high" clock pulses, however, the voltage at a junction (25) between the two transistors is maintained at a value which prevents (totally or substantially) discharge of the capacitor (24) to the input (20). In one arrangement (Figure 2) a third MOS transistor (23) serves to maintain the voltage at the junction (25) between charging of the capacitor at a value determined by the ratio of the sizes of the first and third transistors (21, 23). In another arrangement (Figure 3) the voltage at the junction (25) is maintained between chargings at a value between the "low" value of the pulse ( phi 1) and the input voltage. <IMAGE>

Title: Lithographic reproduction original classification and colour separation tone curve adjustment
IPC: H04N1/407
Filed: 1981-07-02
Abstract: An original to be lithographically reproduced is classified according to density distribution into one of a plurality of classes established on the basis of various high quality standard printed reproductions by comparing the density distribution patterns of the original and the standard reproductions. The patterns indicate relative frequency of density values in the entire density range. After being classified, the original is reproduced utilizing a standard colour separation tone curve for a scanner that corresponds to the compared and selected standard reproduction. Alternatively a reference tone curve based on a grey scale may be used with a correction according to the difference between the reference tone curve and the standard tone curve. Also the reference tone curve may be corrected with the difference between the original density distribution pattern and the selected standard density distribution pattern. An apparatus for use in the processes has a scanning unit (1,2,3) the output of which is representative of the density and is fed to a computer (8). An input processing unit (81) of the computer (8) sorts the input signal into a plurality of ranges to give a density distribution. An operating unit (82) of the computer classifies the density distributor in cooperation with a display (10) on which the density distribution pattern of the original and those of the standard reproductions are shown successively or superimposed, for comparison and selection and its output is stored in a storing unit (83) and is used for reproduction. <IMAGE>
