Title: Improvements in or relating to automatic painting plant
Inventor: CHRISTENSEN EGON VERNER
IPC: B05B12/12
Filed: 1967-12-27
Abstract: 1,209,651. Spraying. H. NIELSEN & SON MASKINFABRIK A/S. 27 Dec., 1967, No. 58724/67. Heading B2L. A flat plate 6 carried in the horizontal position is sprayed on both sides by spray guns 7 and 8 (not shown) which guns are controlled by sensing members which determine the length, width and rate of movement of the plate. A fixed detector 24 senses the leading edge of the plate and sets in operation a magnetic vane counter S 1  which being driven by the roller conveyor allows the leading edge to reach the gun 7 before spraying commences. The counter is then reset and allows for the trailing edge to reach the gun 7 before shutting off the paint supply. Detectors 25, 26 are moved outwardly to find the edge of the plate and thus control, through potentiometers, the transverse stroke of the guns 7.. A similar counter to S 1  measures the speed of the sheet and accordingly varies the speed of the transverse stroke of the guns. If plates with non-parallel sides are sprayed the narrowest end must pass through the machine first since the detectors 25, 26 only operate in the outward direction to locate the edges.

Abstract: 1293176 Preserving latex RUBBER RESEARCH INSTITUTE OF MALAYA 1 Dec 1970 [4 Dec 1969] 59379/69 Heading C3E A method of preserving field latex of Hevea, either diluted or undiluted, from coagulation, comprises maintaining the pH of the latex at a value of at least 8, preferably 8À5 to 9À5, by the repeated addition thereto of a nitrogenous base or by a single or repeated addition thereto of urea or by making at least one addition thereto of a nitrogenous base and at least one addition of urea. The nitrogenous base is preferably ammonia but an organic amine is also suitable. The pH of the latex is preferably maintained at a pH of about 9, e.g. 8À5 to 9À5. The initial concentration of ammonia may be 0À05-0À1% by weight of the latex and the total weight of ammonia that is added incrementally over the period until the pH stabilizes may be 0À3- 0À5% by weight. The addition of 0À5-2À0% by weight of urea is sufficient to make further incremental additions of ammonia after the initial pH adjustment unnecessary. Alternatively if urea is used alone an amount in the range 2À0-4À0% by weight is suitable.

Data from the keyboard is supplied to AND gate 15 and when the most significant digit is supplied an index H1 is stored in stage 1 of register 12. Clock pulses shift the H1 bit through register 12 to stage 8. When the bit is returned to stage 1 AND gate 15 is enabled and the digit is fed to the most significant stage of register 10. If no further digits are supplied the digit and H1 bit circulate in synchronism. If a further digit is supplied a control signal I inhibits gate 14 and enables gate 16 so that circulated signal H1 is fed from stage 7 to stage 1 of register 12 and is fed to stage 8 and allows entry of the next most significant digit while the most significant digit is in stage 10 of register 10. A bit H2 is entered into the index register. A similar procedure occurs for the remaining digits. On display the H bits in register 12 set in flip-flop 18 enabling display of appropriate digits. Where an insignificant "0" occurs there is no H bit in the index register so no digit is displayed. The most significant digit is displayed on the left of the display.
