Patent GB-1002361-A (GB)
Title: Method of improving the filtration characteristics of asbestos
IPC: C04B28/02
Filed: 1962-12-11
Abstract: An asbestos-cement composition contains up to 70%, preferably 10-40%, asbestos fibre which has been treated in air suspension with an atomized spray of Na and/or K silicate solution (see Division C1). Cement, asbestos, and optionally silica, may be present in the proportions 5 : 2 : 3 resp. by weight.  The treated asbestos may be dispersed in an aqueous slurry of cement and consolidated, e.g. by transferring the slurry solids on to a revolving element where a laminated composite article is built up.ALSO:The filtration characteristics of asbestos are improved by applying an atomized spray of a sodium and/or potassium silicate solution on an air suspension of asbestos to deposit 0.1 to 4% on the fibre.  The solution may contain 3 to 20% silicate having SiO21M2O ratio of 1.6 to 3.75.  Asbestos from screw feed regulator 1 is transported on conveyer 2 to fibrizer 3, e.g. a willow.  The silicate spray from 5 is directed into the willow feed opening, and coats the fibre, which is then pneumatically conveyed to cyclone separator 6.  A moisture content of less than 8% may be ensured by extending this air passage or re-suspending the fibre in a current of air, which may be warm, e.g. at 150 DEG  F. This drying step may be omitted when the coated fibre is used to form asbestos-cement articles by dispersing in an aqueous slurry of cement and transferring the slurry solids to a revolving element where a laminated <PICT:1002361/C1/1> composite article is built up.  Treated asbestos or asbestos-cement slurries were shown to have improved rates of filtration (the latter having an asbestos:silica:cement ratio of 2:3:5).ALSO:Asbestos paper is manufactured from asbestos fibre which has been treated in air suspension with an atomized spray of Na and/or K silicate solution (see Division C1), by forming sand sheets with starch or latex binders.  Asbestos-cement boards are made by dispersing the treated fibres in an aqueous slurry of cement, collecting and withdrawing a wet layer on a collector roll, transferring it to a revolving accumulator element and building up a laminated composite article.

Title: Resonant sensing device
IPC: G01N3/40
Filed: 1965-11-04
Abstract: 1,097,518. Testing materials. BRANSON INSTRUMENTS Inc. Nov. 4, 1965 [Jan. 26, 1965], No. 46757/65. Heading H4D. A test probe 21, Fig. 1, is moved from a normal position to a test position in which it engages the surface of a workpiece 13. In the test position the probe is vibrated at its resonant frequency and the (diamond tipped) end engages the workpiece with a constant force so that the depth of penetration of the tip varies inversely as the hardness. Thus the resonant frequency increases as the hardness of the test piece decreases and measurement is effected, utilizing a known arrangement described with reference to Fig. 4 (not shown), including an excitation coil (42) and a piezo-electric transducer (43). The weight of the probe together with that of a rod (37, Fig. 2, not shown), a plunger (38) in a sleeve ball bearing (40)- fastened to housing (20)-and a bracket 35 (additional weights, if required, being placed on the top of the latter via a removable plug 85) produces the constant force of engagement when the probe is lowered from the normal position, in which the bracket (35) is suspended on a lever (32) supported by a compression spring (50), to the test position in which, when lever (32) is pulled down by electro-magnetic means (23) including a dashpot arrangement 70, the probe rests on the workpiece whilst lever (32) remains clear of bracket (35). When adjusted for operation by means of lever 18 and knob 19, the tip of the probe is about 0À10 inch from the workpiece, a microscope 26 being utilized to select the precise spot to be contacted in conjunction with position adjusting means 14, 15. A push-button operated control circuit permitting measurements to be made at single discrete spots selected by the means 14, 15 or, by replacing at least one of the latter means by a step motor, at a succession of adjacent spots, is described with reference to Figs. 3 and 5 (not shown).
Patent GB-1568986-A (GB)
Title: Process for spraying articles
IPC: C25D21/08
Filed: 1976-11-10
Abstract: The article (5) to be treated, after immersion in the active bath (1), is for washing not immersed in a number of washing baths which are connected one after another and also serve as storage containers for the washing liquid, but is brought into an arrangement, situated e.g. above the active bath (1), with a spraying chamber (4), in which the washing takes place by means of spraying lines (6) and nozzles. In this case, a washing-water collecting tray (3) has been brought under the spraying chamber (4), from which the washing water is conducted to storage containers. It is consequently possible to forgo a number of washing stations. The passage time of the articles to be treated is shorter. The storage containers for the washing water can be accommodated at a distance from the active bath (1), e.g. in the basement. The floor space requirement for the installation in the room, in which the active bath (1) is situated, is consequently reduced. The shape of the storage containers for the washing water does not depend on the shape of the articles to be treated and an inexpensive shape can consequently be selected. The arrangement is suitable e.g. for installations for galvanising, bonderising or anodising.
