Title: Radiation responsive position detectors
IPC: G01D5/26
Filed: 1970-09-02
Abstract: 1356380 Measuring the lengths of billets DECCA Ltd 31 Aug 1971 [2 Sept 1970] 42021/70 Heading G1A In a device for measuring the length of moving billets 12 moving along a conveyer belt 11, a photo-cell 1 and a mask 2 with an elongated slit are surrounded by a rotating cylinder 5 having a number of axially aligned slits 6. The cylinder is in a sealed enclosure 7 with a window of polarizing material and the radiation received by the photo-cell 1 can be that due to the moving billet itself (red hot) or that due to a source placed inside the cylinder which directs radiation on to the billet so as to be reflected back to the photo-cell. A series of reference pulses are produced by a lamp 3 and a photo-cell 4 and by electronically measuring the time elapsed between the "nearest" reference pulse and the appearance of the first pulse of radiation detected by the photo-cell 1 from the nearest end of the billet 12, a measure of the cylinder's charge in angular position # (see Fig. 2) is obtained. This measurement can be used to provide a measurement of the distance of the end (being viewed) of the billet from a plane passing through the lamp 3 and photo-cell 4 and hence a measurement of the billets length can be calculated since the other end of the billet can be sensed by a detector 13, preferably of the beam interruption type. Two embodiments are disclosed one in which the rotating cylinder is directly above the conveyer belt and the photo-cell is mid-way on the principal axis of the cylinder, and the other in which the cylinder is to one side of the conveyer belt and the photo-cell is at one end of the principal axis of the cylinder.

Title: Hydrogen peroxide
IPC: B01J31/10
Filed: 1961-11-24
Abstract: <PICT:0937359/III/1> <PICT:0937359/III/2> An aqueous solution of hydrogen peroxide is produced by reacting peracetic acid and water in contact with a synthetic sulphonic cation exchange resin free from heavy metal ion, and substantially insoluble in and resistant to oxidation by said peracetic acid and water mixture at from 20 DEG  to 90 DEG C., distilling the resulting mixture of hydrogen peroxide, acetic acid, peracetic acid and water by vacuum fractional distillation to separate peracetic acid, water and acetic acid from hydrogen peroxide, and recovering a hydrogen peroxide aqueous solution.  Examples of resins which may be used are the sulphonated polymers of polyvinyl aryl compounds, e.g. divinyl benzene, and the sulphonated copolymers of such polyvinyl aryl compounds with monovinyl aryl compounds such as styrene.  The resin is conditioned before use, for example by washing it with an aqueous solution of 10% HCl, exhausting with 10% NaCl, regenerating with 10% HCl and then washing with de-ionized water.  At least 0,2 parts of resin are used for every 100 parts of peracetic acid.  In Fig. 1, the peracetic acid-water solution is passed from feed funnel 2, through heating zone 3, to resin bed 1 which may be heated by a hot water jacket, and the treated solution is collected in reservoir 4 and then passed to fractionation column 5 equipped with heating coil or reboiler 6. Peracetic acid and water are removed from the top of column 5, condensed and may be recycled.  The residue from column 5, acetic acid, hydrogen peroxide and water, is passed into a second fractionating column 11, the overhead products of acetic acid and water are removed and the residue which is a concentrated aqueous hydrogen peroxide solution is collected in reservoir 14.  Columns 5 and 11 are operated under vacuum (below 300 mm. Hg).  Water is added to columns 5 and 11, at ports 18 and 19, if the distillation is performed at a vacuum above 50 mm. Hg and the peroxide concentration in the residue reaches 90% or above.  In Fig. 2, peracetic acid, acetic acid and water are removed from the top of column 5, condensed by 7, collected in reservoir 20 and then passed into fractionation column 11 where peracetic acid and water are removed from the top, then condensed and may be recycled to the resin bed, while acetic acid is collected in reservoir 14.  Concentrated aqueous hydrogen peroxide solution is recovered as residue from column 5 in reservoir 10 and may be used as such or subjected to flash evaporation under vacuum.  As before, water may be added to column 5.  If desired two or more resin beds may be used if the process is to be continuous.

Title: Paper coating compositions and paper coated therewith
IPC: D21H19/62
Filed: 1969-08-25
Abstract: 1285760 Polymer compositions BERGSTROM PAPER CO 25 Aug 1969 [7 Jan 1969] 42326/69 Headings C3R and C3P A non-aqueous homogeneous composition of paper coating fluidity comprises an organic polymeric adhesive or a monomer or prepolymer precursor thereof as binder, and a pigment/ organic compound constituent which per se is a non-aqueous soft and friable aggregate free from solvent for the organic compound, the organic compound being hydrogen-and/or hydroxylreactive, and the pigment being of average particle diameter 0À2-5 microns and constituting 35% by wt. of the solids of the composition. The reactive compound may be a mono-, di- or polyisocyanate, a haloalkylsilane, a polyhalosilane of 1-16 carbon atoms or a Grignard reagent, constituting 0À1-20% by wt. of the pigment. The pigment may be an organic or inorganic pigment or filler, e.g. kaolin, bentonite, fuller's earth, CaCO 3 , TiO 2 , SiO 2 , BaSO 4 , quinacridone red or phthalocyanine blue. The adhesive may be thermosetting or thermoplastic, e.g. a polyester or polyvinyl-chloride, and it is preferred that a "binder component" react with the H- and/or OH-reactive component to form the binder or adhesive. To prepare the composition the pigment and organic compound are mixed, preferably dry, but alternatively with a small amount of solvent which is subsequently removed. The pigment/organic compound is then dispersed in the binder with a reduction in viscosity. The coating composition at this stage may include an organic solvent in an amount 10-30% by wt. of the modified pigment, particularly an ester-aromatic hydrocarbon mixture, and a polymerization catalyst as required. The binder constituent preferably constitutes 10-25% by wt., based on the untreated pigment solids, and the total solids weight may be 60-95% of the coating composition. Thus pigment solids weight is at least 35%, and may be at least 70%, of the composition. In Example 7 clay pigment is treated with different amounts of toluene diisocyanate and mixed with a polyurethane binder (prepared in Example 6), stannous octoate catalyst, and nbutyl acetate/xylene solvent. In Example 8 a similar composition is made in which the clay pigment is treated with toluene diisocyanate as in Example 1, and a total solids content of 70% is obtained. In Example 9 a binder obtained by mixing an alkyd resin/styrene polyester resin with benzoyl peroxide in styrene is diluted with methyl ethyl ketone and the treated pigment of Example 1 is dispersed therein.

Abstract: In manufacturing a glass-ceramic material, lead borate glass or lead borate glass forming material is mixed with fluor-mica or fluor-mica forming material, the mixture produced is smelted at a temperature of between 450 DEG  and 1365 DEG  C., the smelt is quenched to form a frit, the frit is ground and is then pressed to form a preform, the preform is fired at a temperature of between about 800 DEG  and 1100 DEG  C., and the fired preform is cooled to cause mica to precipitate from the glass.  Thus, a lead borate glass composed essentially of 50-92% lead oxide (preferably 81.6%) and 50-8% boron trioxide (preferably 18.4%) and in the form of a frit ground to 200 mesh particle size, is mixed with ground normal fluor-phlogopite mica or taeniolite mica or the stoichiometrically equivalent ground raw materials (specified) preferably in the ratio 60 (glass): 40 (mica), and the mixture produced is smelted in a gas-heated smelter at about 1200 DEG  C. for 20-30 minutes for a 75 lb. batch.  The smelt is quenched in water to produce a frit which is dried in an oven at 120 DEG  C. and then ground to 200 mesh particle size.  The finely ground frit is mixed with between 5% and 90% (preferably 10%), based on the total weight, of mica of about 2 to 10 microns (preferably 5 microns) grain size and water is added in a proportion of up to 10% by weight as a temporary binder.  The mixture of mica, frit and water is cold pressed at 2000-10,000 (preferably 3000) lb. per sq. inch pressure, is baked at 120 DEG  C. to drive off all the water, is fired at a temperature of between about 800 and 1100 DEG  C. (preferably 980 DEG C.) for sufficient time to achieve thermochemical equilibrium, and finally is cooled.  The heating to and cooling from the firing temperature are preferably conducted at a rate of 150 DEG C. per hour.  A typical product has a dielectric constant of 7.4, a dissipation factor of 0.001 at 1 megacycle, and a volume resistivity of 5 x 1014 ohm-centimetres at room temperature and 107 ohm-centimetres at 500 DEG  C.

Abstract: 1,239,783. X-ray apparatus. PICKER CORP. 5 Sept., 1968 [8 Sept., 1967], No. 42336/68. Heading H5R. An X-ray apparatus has movable shutters, 33 defining an aperture through which X-rays are directed to an object, e.g. patient 34 under examination, servo means for adjusting the relative positions of the shutters, and a selector having a plurality of discrete operative settings for selectively controlling the energization of the servo means whereby the shutters may define only apertures corresponding to a discrete number of preselected exposure sizes in accordance with the settings of the selector. The spot filmer 30 movable towards and away from the patient, contains a shown in more detail in Fig. 2, selector switch 66 rotatable so as to occupy any one of the positions illustrated on scale 80. The spot filmer may be adapted so that selection of one position controls the positioning of the record carrier, e.g. cassette, 42 in the X-ray beam and a sequence of exposures may be recorded in separate positions on the cassette by stepping the switch 66 through the series of positions. If desired one of the positions available to the switch 66 may be such that the shutter system 33 is then only responsive to the operation of the manual controls 70A, 70B. In the preferred embodiment the positioning of the switch 66 controls the positioning of a number of cams 74 which interact with a number of appropriately positioned contacts 76 to apply signals corresponding to the desired position to the servo means. The available switch positions may include, shutters fully open, shutters fully closed, four consecutive settings in which the shutter setting remains constant, i.e. both pairs half open, and the cassette carrier is positioned to expose different quandrants in turn; two pairs of settings in which one pair of shutters is either fully open or half shut, the second pair of shutters being correspondingly half shut or fully open, when the cassette carrier is positioned to consecutively expose either two halves of the film longitudinally divided or two halves of the film transversely divided. Other positions of the switch may be adapted to position the shutters in any given setting favoured by the radiographer. The spot film device 30 may be adapted to index the switch 66 through any given sequence automatically once the first of the sequence has been selected. The Specification describes a switch and resistance network by means of which the desired operation of the servo means is attained.
