Title: A process for pickling and passivating hollow metal structures
IPC: C23G1/00
Filed: 1960-06-02
Abstract: Hollow iron or ferrous metal structures, e.g. heat exchanges, boilers, gas generators or storage tanks are pickled and passivated by filling the structure with a pickling solution with complete removal of air therefrom, allowing the solution to remain in the structure, e.g. for 24 to 48 hours, to dissolve oxides and like impurities such as rust, scale or solder flux from the structure walls, removing the solution by directly replacing it with water until the liquid isuing at the outlet is neutral or, at least, has a pH value of 6 without allowing air to contact the inner surfaces of the structure, replacing the rinsing water directly without draining out by a solution which forms soluble complex ions with any Fe(OH)2 floccules suspended in the structure, e.g. containing a tartrate, citrate or malate, and removing these complex ions by further water rinsing without draining replacing the solution until the pH values at the inlet and outlet are the same.  A passivating solution, e.g. containing an amine or amide acid bichromate, may then be introduced, again without draining out, and allowed to stand or recycled, e.g. for 1 to 24 hours, prior to finally draining out. Each new solution or rinsing water may be substituted for the preceding one by introducing it at the top whilst draining at the bottom of the structure. The pickling solution may be allowed to stand in the structure or continuously circulated or alternatively allowed to stand and circulated. After treatment, the structure may be exhausted by suction applied at the bottom after sealing all apertures, and dried by introducing a current of dry oxygen at the bottom. Specification 647,782 is referred to.
Patent GB-446386-A (GB)
Title: Improvements in and relating to methods of forming ceramic products
IPC: C04B33/13
Filed: 1935-07-09
Abstract: Clay for porcelain insulators and other ware is produced by adding to the slip an alkaline reagent to deflocculate, and then effecting a retarded coagulation or flocculation to a plastic condition by forcing the deflocculated slip through a constricted orifice at high speed and simultaneously injecting into it a reflocculating substance having a delayed action.  The reflocculent consists of a dehydrated mixture of alkaline earth oxides in an oleous vehicle such as benzol, benzine gasoline, coal oil, paraffin oil, lubricating oil, wax, ceresin, carbon tetrachloride, or other animal or vegetable oils. For example, natural limestone containing 3 per cent of an oxide of silicon, iron, aluminium, magnesium, or other alkali is burnt, mixed with kerosene and lanolin, and used as a flocculent.  Apparatus is described for introducing the flocculent into a stream of deflocculated slip, and comprises a pump to force the slip through a restricted orifice in the centre of which is a small pipe through which the flocculent is forced; thence the mix passes into a small space containing two high speed blade rotors revolving in opposite directions, and is poured directly into plaster moulds.  U.S.A. Specification 1,528,908 is referred to.

[Also in Division F1] In an axial piston pump in which the inlets 88, 88-A to the cylinder bores 76 are controlled by the pistons 62 and in which the cylinder block 70 is axially slidable to vary the timing of the closure of the inlets by control means which includes an annular piston 146 acting on the cylinder block in opposition to a spring 142, the annular piston is subjected to the pressure in an annular chamber 150 defined between the piston and pump housing 22. The output pressure of the pump is applied to the chamber 150 under the control of a valve 135 having a spool member 164 provided with adjustable spring loading which determines the pressure at which the chamber is communicated with the pump output through passages 122, 140, 144, 147, spool cylinder 149 and passages 130, 154, 158, 160, 162. The liquid supplied to chamber 150 is exhausted therefrom and returned to the interior 86 of the housing 22 via an orifice 232 and passage 226. A check valve 180 is provided in parallel with orifice 232 to limit the pressure in chamber 150. The orifice 232 provides a low flow rate leakage from chamber 150 and thus the spring 142 biases the cylinder block 70 to provide increased pump output unless the output pressure exceeds the desired outlet pressure determined by the loading of spool 164.

Title: Improvements in or relating to synthetic resinous compositions and to products formed therefrom
IPC: C08G8/00
Filed: 1946-07-03
Abstract: A synthetic resinous composition hardenable at room or moderately raised temperature comprises a mixture of phenol-formaldehyde resol, an acid accelerator and 0.1-15 per cent of polyvinyl acetate, of partly hydrolysed polyvinyl acetate, of polyvinyl alcohol, or mixtures of two or more of these materials.  The resol is formed from a phenol or a cresol and may be solid, liquid or a solution or dispersion of solid resin. Suitable accelerators are hydrochloric, sulphuric or a sulphonic acid.  The accelerator is preferably added just before hardening, but the polyvinyl compound may be added to the phenol before reaction with the formaldehyde or during or after the reaction with the formaldehyde.  The polyvinyl compound may be mixed with the acid accelerator.  They may be dissolved or dispersed in solvents before incorporation.  The products may be cast, used as adhesives, for the formation of expanded resins by inclusion of a gas generator or they may be dissolved to form lacquers or varnishes. Suitable solvents are methyl ethyl or butyl alcohol, methyl ethyl ketone or ethyl acetate.  In examples: (1) phenol and /or aldehyde were refluxed with sodium hydroxide and the product dehydrated.  The liquid resin is mixed with an alcoholic solution of polyvinyl butyral and sulphuric acid added to harden the mixture.  The product may be used for sticking synthetic resin mouldings or for securing bristles in their holders; (2) polyvinyl alcohol is used instead of the butyral and hydrochloric instead of sulphuric acid; (3) polyvinyl acetate is mixed with p-toluene sulphonic acid and the mixture added to a liquid resin as in example (1).  The product in solution in methylated spirit may be applied to acid-resisting paper, and abrasive grit is sprinkled on and the composition air-dried.  A sizing coat of the resinous composition may then be applied. Reference has been directed by the Comptroller to Specification 553,437.

Abstract: 815,089. Photo-conductive devices. THORN ELECTRICAL INDUSTRIES Ltd. June 19, 1956 [July 8, 1955], No. 19875/55. Class 37. [Also in Groups XL (a) and XL (b)] A photo-conductive device consists of two photo-conductive layers 18, 19, separated by an opaque layer 20 and sandwiched between two transparent conductive electrodes 17, 21. It is employed combined with a photo-conductiveelectroluminescent panel 2 ... 6 which produces a scanning spot of light (see Group XL (a)) to form a television signal generator. This light spot affects layer 18 through glass support 1, while the scene 22 affects layer 19. Only where both layers are affected is there a conductive path between the electrodes so that the output at 24 is a measure of the instantaneous intensity of the scene at the point where the light spot is. Layer 20 may be non-conductive, when alternating bias is necessary; or conducting for D.C. bias, but retaining sufficient transverse resistance for proper resolution. Specifications 798,503 and 798,504, [both in Group XL (a)], are referred to.
