Title: Method and Apparatus for Preparing Foundry Moulds.

IPC: B22C15/08
Filed: 1967-02-12
Abstract: 1,179,118. Sand packing. ZAVOD  " ELPROM." 12 Feb., 1967, No. 55644/66. Heading B3F. In a method of making a mould, sand introduced into a flask 3 is compacted between a fixed plate 7 and a movable compacting plate ], the flask moving in the direction of the packing plate 1 as the compaction of the sand is effected. Filling frames 2, 9 may be positioned respectively above and below the flask, the height of the frames being directly proportional to the extent of compaction required and the nature of the sand being compacted. At the commencement of the compacting operation the flask and frames are supported on a rod 6 and a push member 8 or spring 10, the resistance of which is overcome by the force exerted by the packing plate 1, thereby allowing movement of the flask and frame assembly as the sand is compacted. In the above arrangement the compacting pressures on each end of the mould are equal and are transmitted only through the sand. In an alternative embodiment the filling frames are omitted and an ejector device is provided to remove the mould from the flask.

Specified corrosive substances are sulphuric nitric and perchloric acid, zinc chloride, bromide and nitrate, triethanolamine, benzene sulphonic acid, ethylene glycol, guanidine carbonate and hexamethylene diamine. which may be applied in the form of aqueous sprays or as powders which are moistened. The corrosive substance may be applied together with an organic swelling agent, e.g. benzoic acid, methyl benzoate, salicyclic acid, methyl salicylate, phenol, resorcin, pyrogallol, o-chlorophenol, m-cresol, o- and p-dichlorobenzene, dimethylformamide, dimethylsulphoxide, monochlorobenzene and a mixture of phenol and tetrachloroethane. After treatment with the corrosive substance and heating, the article may be treated with an aqueous solution containing a nonionic surfactant such as a polyoxethylene phenol ether, and an acid, e.g. formic, acetic, hydrochloric or sulphuric acid at a pH lower than 3.5 or an aqueous solution of a non-ionic surfactant and a sequestering agent, e.g. polyphosphoric acid salts and salts of EDTA and nitrilotriacetic acid, at a temperature of 40-90‹C. The article is also rendered soft, anticrease and antistatic.

Title: Systems and methods for testing integrated circuits
IPC: G06F11/22
Filed: 1972-12-04
Abstract: 1363786 Testing integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 4 Dec 1972 [13 Dec 1971] 55853/73 Heading G1U A integrated circuit tester of the type that applies a sequence of pseudo-random test signals to the inputs of the i.c., is characterised in that the probability distribution of the random signals is not uniform as in the prior art but is weighted whereby the inputs to the i.c. are no longer equally likely to be selected. This is clearly desirable once it is recognized that some inputs of the i.c. may go, for example, to a counting chain of triggers whereas others may go simply, for example, to a gate, since in order to test the last trigger of the chain a large number of input signals must be applied to the beginning of the chain. As described, the output.from a random number generator 10, Fig. 1, having a uniform probability distribution, is decoded 14 to mark one of a set of leads 0, 1, 2, ..., which are mixed 18, in accordance with an empirically determined weighting pattern for a particular i.c., and applied to a bank of bistables 16 (details) Fig. 2, (not shown) each of which changes its state on receipt of an input signal, and the outputs of the bistables are applied to the inputs of the i.c. As shown, for example, the first trigger of the bank 16 will change its state, on the average, four times more frequently than the second trigger. The weighting pattern for a particular i.c. is preferably determined by sinulating the i.c. in a computer, applying test signals to it, noting the switching activites within the i.c., and progressively modifying the weighting applied to the random test signals until the elements of the i.c. are all tested equally frequently except for those (such as the trigger at the beginning of a counter) which have to be tested more frequently in order to ensure that none (e.g. the trigger at the end of a counter) is not tested sufficiently often.

Abstract: 1,217,130. Arylphenols. CHEVRON RESEAKCH CO. 12 Dec., 1969 [27 Dec., 1968], No. 60864/69. Heading C2C. [Also in Division A5E] A monoarylphenol in which the aryl group has 6-18 carbon atoms and is bound to the phenol nucleus by a nuclear carbon atom, is isomerized to corresponding position isomers by heating to 160-250‹ C. in the presence of an acid-activated Montmorillonite clay. The aryl group may be, for example, phenyl, tolyl, naphthyl, cumyl, anisyl. phenoxyphenyl, xylyl, butylphenyl, amylphenyl, decylphenyl, dodecylphenyl and naphthylphenyl. The isomerization may be carried out in the presence of a diluent, e.g. phenol, If desired, a phenylphenol may be simultaneously alkylated and isomerized by reacting a monophenylphenyl with an alkylating agent in the presence of the Montmorillonite clay. Examples are given of the isomerization of (a) o-phenylphenol to m- and p-phenylphenol; (b) p-phenylphenol to o- and m-phenylphenol, and (c) the reaction of o-phenylphenol and o-sec.-butylphenol in the presence of Montmorillonite to give 3-sec.-butyl-5-phenylphenol. The arylphenols may be carbamoylated, e.g. 3-sec.-butyl-5-phenylphenol is treated with methyl isocyanate in the presence of triethylamine to give 3-biphenyl-5-sec.-butyl-N-methylcarbonate.

IPC: B01D21/00
Abstract: 695,239. Treating sewage and waste waters. HEYMANN, H. May 24, 1951 [May 30, 1950], No. 12130/51. Class 111 [Also in Group II] Mechanical and chemical purification take place either separately. or simultaneously and are effected in a multisectional vibrating flow channel. For mixing added chemicals with the waste water an immersion agitator is preferably used which carries out, about a fixed pole, vibrations which decrease in the direction of the pole. Waste water is introduced at 1 behind a baffle 5 of a flow-channel 1 suspended by leaf springs 2 from a frame 3 and vibrated in the direction of its length by a rotating unbalanced mass 4. The solids formerly in suspension, settled and well compacted by the motion, pass through the opening 6 and a resilient channel 7 into a container 8 with a floating cover 9, while the effluent flows over a resilient tongue 12 connected to a cock on a reagent inflow pipe 14. Settled effluent together with an appropriate quantity of reagent thus flows into a shallow gutter 17 connected to a second settling channel 18 and suspended, with it, by leaf springs 19 from the frame 3. The combined structure 17, 18 is likewise vibrated in the direction of its length by a rotating unbalanced mass 16. In addition, mixing of the water and reagent in the gutter 17 is effected by an agitator 20 comprising a platform with downwardly-extending vanes 27 which is suspended from the frame 3 by two leaf springs 23, is further connected to the frame 3 by a leaf spring 21 and is oscillated in a horizontal plane about the spring 21 as pole (after the manner of a horizontal pendulum), by an unbalanced mass 24 rotating in bearings 25. The turbulence imparted to the liquid thus progressively decreases from the influent end to the effluent end of the gutter. The solids produced by the chemical action are settled in the channel 18 and collected in a container 30. The vanes 27 are arranged obliquely to the direction of flow, the setting angle being adjustable. The mechanical vibrations of the channels 1 and 18 are such that no turbulence is imparted to the liquid.

Concrete filling may be carried out directly in the boring tube 1, which latter is raised as concreting progresses, Fig. 4. Alternatively a sleeve F, Fig. 5, is placed inside the boring tube 1 and then filled with concrete. In another modification the bottom of the bore is sealed by a flexible plug M, Fig. 6, and dry concrete is then poured into the tube.
