The surface of the metal, e.g. ferrous metal, zinc or galvanized ferrous metal, may first be cleaned by detergent or alkali followed by pickling and rinsing. Specified oxidising agents are H 2 O 2 , dichromate, perborate, bromate, permanganate, nitrite, nitrate and chlorate. The etching acid may be a mineral and, phosphoric acid, acetic, lactic or tartaric acid, fluoroboric, fluorotitanic or fluorosilicic acid, chloroacetic or trichloroacetic acid, polyacrylic acid or HF Many Examples are given in which hot-rolled and cold-rolled steel panels and rods are coated using various compositions and conditions. The coatings comprise both organic and inorganic components (see Specification 1,349,826). Preferred coatings are soluble in toluene to at least 50% and show a pattern of light strations on a dark grey background, indicating a high organic content. The coatings prevent metal-to-metal contact during subsequent working of the metal.

Patent GB-816110-A (GB)
Title: Process for the production of polymers
IPC: C08F10/00
Filed: 1955-10-05
Abstract: In a continuous process for the polymerization of ethylene at elevated temperature and a pressure of at least 5000 p.s.i., ethylene is passed through an elongated reaction zone of small cross-section relative to length, and there is <FORM:0816110/IV (a)/1> imparted to the flowing reaction mixture, marked flow pulses at regular time intervals of such frequency and magnitude as to substantially eliminate irregular changes in pressure and rate of flow originating from other causes.  The flow pulses are obtained, either by the periodic opening and closing of the outlet and of the reaction zone while maintaining a substantially constant rate of inflow; by varying the inlet flow by pumps or intensifiers while maintaining a substantially constant outlet from the reaction zone; or alternatively opening the pressure release valve and simultaneously increasing the rate of ethylene input to increase the velocity of ethylene flow, and then closing the valve and simultaneously reducing the rate of ethylene input in order to avoid any substantial change in reaction pressure.  A 5 to 25 per cent inlet pressure change is preferred and the outlet may be opened instantaneously, preferably at least once every two minutes, into a lower pressure zone to produce pulses which make at least a two-fold increase in the linear velocity of the reaction mixture through the zone.  In an example, ethylene alone, or with up to 30 per cent of a comonomer, and containing oxygen in an amount below 500 p.p.m., is passed at 25,000 p.s.i., and 240 DEG  C. through a jacketed reaction tube, Fig. 1, 10, a pump 22, a preheater 26 and regulating valve, 30.  The ratio of the length to the diameter of the tube may be from 300 to 1000 to 1, and it is jacketed, 12, 14 and 16, for heat exchange media.  The tube leads to a pressure release valve 32, which may be operated manually or co-ordinated by electrical or pneumatic control line 46, to maintain the pressure within the required limits, and a timer 48 is preset to open and close the valve at predetermined intervals to make the pressure flow pulses.  In a cycle in which a pressure of 25,000 p.s.i. is held for 5 seconds, allowed to drop to 1500, and returned to 25,000 the sojourn in the tube is 11 minutes, and polyethylene, free from carbon black, is recovered from the separator 34, in a yield of 25 per cent.  Specifications 471,590 and 497,643, [both in Group IV], are referred to.
Patent GB-1387543-A (GB)
Title: Directional flow control arrangements
IPC: F15B13/06
Filed: 1973-06-14
Abstract: 1387543 Power steering mechanism COMMERCIAL SHEARING Inc 14 June 1973 [14 June 1972] 28407/73 Heading B7H [Also in Division F2] A directional flow control valve arrangement for selectively operating a first fluid motor in two directions at a controlled speed includes overflow valve means controlling flow to a second fluid motor. The arrangement may be applied to a vehicle in which the first motor controls steering and the second a loading bucket. The arrangement comprises a valve housing 10 having a bore 11 containing a directional control spool 12 and bores 32, 33 containing spools 33, 43 respectively. The housing includes inlet chambers 19, 20 supplied by a pump 29, ports 15, 16 leading to opposite sides of the steering motor, exhaust ports 13, 14 and an overflow outlet 44 leading to the bucket motor. In the neutral position shown, of directional spool 12, fluid pumped to inlet chambers 19, 20 flows around spool 33 which is biased to the right by spring 35 and thence causes spool 43 to move rightwards against spring 45 and open bucket outlet 44. The latter thus receives the total output of pump 29. When spool 12 is indexed rightwards the chamber 17 adjacent spool 33 communicates via chamber 21 and non-return valve 21c within spool 12 with steering outlet 15. Simultaneously chamber 17 communicates via spool passages 23, 25 with passages 36, 46 leading respectively to the backs of spools 33, 43. Thus spool 43 moves leftwards to reduce the flow through bucket outlet 44, whereas spool 33 moves leftwards to connect inlet chambers 19, 20 with chamber 17 and steering outlet 15. Any tendency of the external pressure to vary the amount of fluid directed through outlet 15 will be automatically compensated by movement of spool 33. Flow of fluid through outlet 16 for steering in the opposite direction is effected in similar manner by indexing spool 12 to the left. The arrangement thus ensures that steering flow is given priority over bucket flow. In the event of malfunction of either of spools 33 or 43, spool 12 can be shifted in either direction to an extreme position beyond that normally required for metered control and in which port 30 is blocked and all fluid pumped to chamber 19 flows directly to chamber 17 for steering control. In this state spool 33 assumes its rightwards position and acts as a non-return valve preventing backflow of fluid through port 37. The bucket flow leaving outlet 44 may be supplemented by flow from an additional pump (52, Fig. 2, not shown).
