Title: A saw blade planishing machine
IPC: B23D63/18
Filed: 1947-03-28
Abstract: 628,025. Planishing. SENARD, P. March 28, 1947, No. 8540. Convention date, May 15, 1946. [Class 83 (iv)] A saw-blade planishing-machine comprises a block 1 for supporting the band saw blade 2, means to move the blade longitudinally forwards thereon intermittently, a set of feelers 16, a set of compressed-air hammers 5 and electric control means whereby the hammers operate or not depending on whether the related feelers are in engagement with swelledout or even portions of the blade 2. The hammers 5 are contained in a frame 7 and urged upwards by springs 10, supply of pressure air being regulated by valve 12 operated by electromagnets 13. The feelers, arranged in a carriage 14 slidable between guides 15 in the frame 7, each comprise a needle 16 vertically slidable and normally supported on a support rail 19 vertically reciprocable by a cam-operated rack 21 and pinion 20. The carriage 14 is reciprocated by a motor-operated shaft 33 and cam 32 such that at the end of its forward stroke apertures in the carriage through which the hammers can freely project are positioned beneath the hammers, at the end of the return stroke the needles 16 are positioned beneath the hammers. The reciprocating motion of the carriage 14 also serves to intermittently rotate the rubber-lined rollers 3 and 4 to advance the blade 2 by about 5 mm. to 20 mm. at every back stroke. In order that the whole row of hammers may be caused to act upon saws of various widths the block 1 may be set about a pivot 100 and the frame 7 is capable of transverse reciprocation by a few millimetres on guides 35 on a fixed frame 56, by cams on a shaft coupled with the shaft 33 so that the frame 7 is reciprocated once transversely while carriage 14 is reciprocated twice longitudinally. The hammers may have rectangular heads which may be set in any desired direction by racks co-operating with pinions on the hammer stems 6. The block 1 accommodates saws of various widths between guide-members 46, 47 of which the members 47 are adjusted by racks 50 and pinion 51 operating on slides 49 at each end of a bar 48 supporting the members 47. In modifications the feelers may be on the opposite side of the blade from the hammers, the necessity for a reciprocating carriage 14 being thereby eliminated, and the block may be arranged vertically or obliquely instead of horizontally, the hammers and feelers being guided at right-angles thereto.

Patent GB-915179-A (GB)
Title: Process for producing titanium oxychloride with or without titanium dioxide
IPC: C01G23/02
Filed: 1961-03-09
Abstract: Amorphous titanium oxychloride, with or without titanium dioxide, is produced by reacting titanium tetrachloride and nitrogen dioxide at a temperature not greater than 450 DEG C.  At temperatures below 300 DEG C. the reaction product is entirely amorphous titanium oxychloride whilst at temperatures from 300 DEG  to 450 DEG C. some crystalline titanium dioxide is produced, the amount of titanium dioxide formed increasing with increase in temperature.  The reaction products whether produced below 300 DEG C. or from 300 DEG  to 450 DEG C. may be given a low temperature calcination, i.e. heated in air at 200 DEG  to 400 DEG C. for 1 to 24 hours, to form a product consisting entirely of titanium dioxide, 40 to 60% being non-crystalline or amorphous and 40 to 60% being in the anatase form. The titanium dioxide thus produced may be converted entirely to anatase or rutile by adding a small amount of the appropriate promoter and/or inhibitor and calcining.  A list of suitable promotors and/or inhibitors is given.  The reaction between NO2 and TiCl4 may take place with both reactants in the gas phase, with both reactants in the liquid phase or with the TiCl4 in the liquid phase and the NO2 in the gas phase.  The vapour phase procedure is preferably carried out at 140 DEG  to 450 DEG C.  For reactions in which the TiCl4 is in the liquid phase and the NO2 in the vapour phase the temperature is conveniently from room temperature to the boiling point of pure TiCl4 or up to the critical temperature for the solvent system when a solution is used.  The liquid phase process is preferably carried out between 0 DEG  and 20 DEG C. at atmospheric pressure, and at higher temperatures when superatmospheric pressures are used.  Nitrosyl chloride and chlorine, produced in addition to the reaction product, may be separated therefrom and the gas mixture separated into its two fractions.  The NOCl is preferably oxidized to produce NO2 and Cl2, chlorine being separated by fractional distillation and the NO2 recycled.  Thus, a stoichiometric mixture of oxygen and nitrosyl chloride, both of 90% purity, preheated to 175 DEG C. at 4 atmospheres pressure is reacted adiabatically, the mixture thus being heated to 350 DEG C.  The effluent gases are condensed and nitrogen and unreacted oxygen bled off.  The condensed product is fractionally distilled to remove pure dinitrogen tetroxide as bottoms and mixture of chlorine and nitrosyl chloride from the top.  The latter mixture is fractionally distilled to give chlorine, removed as product, and a mixture of nitrosyl chloride and chlorine which is returned to the oxidation zone.

Title: An improved process for producing cellulose esters
IPC: C08B1/02
Filed: 1933-03-24
Abstract: Cellulose material to be used in the production of cellulose esters is soaked with an organic liquid having a swelling action, the quantity being sufficient at least for the material to be wetted right through, the bulk of liquid is then removed, sufficient being left to moisten the fibres of the cellulose so that there are free interstices containing air and vapour of the swelling liquid left between the fibres throughout the mass.  The material is then left to itself, preferably in a closed chamber, without any air or other inert gas being drawn therethrough.  The treatment increases the reactivity of the cellulose in the subsequent esterification.  The treatment may be carried out at raised temperature up to the boiling point of the treatment liquid and at raised pressure.  The treatment liquid may be glacial acetic acid, ethyl acetate, or formic acid, or other organic acid, ester or alcohol.  Saturation of the cellulose with liquid may take place in a drum filter, or centrifuge and subsequent removal of the bulk of liquid may take place in a centrifuge, filter press, or on a running belt.  The treatment liquid should be one which does not adversely affect the subsequent esterification.  If the esterification is to take place without solution of the ester, the treatment liquid is preferably a non-solvent such as ethyl p  acetate or ethyl acetate and glacial acetic acid.  In an example, cotton linters are flushed with glacial acetic acid in a centrifuge and the bulk of liquid is then removed. The mass is loosened in a shredder and then left in a closed vessel for several hours.  It is treated with glacial acetic acid containing a little sulphuric acid and after standing for an hour, acetic anhydride and benzene are added.  The mixture is kept cool and at intervals the acetylation liquid is renewed.  The fibrous cellulose acetate is washed in acetic acid and benzene.  The product is soluble in methylene chloride, and formic acid.  The swelling liquid may contain water or other non-swelling liquid.
