Title: Methods of and apparatus for testing sintered products and controlling their production
Inventor: CARLSEN HENRIK ARTHUR
IPC: G01N15/08
Filed: 1961-03-01
Abstract: 930,857. Testing sintered products. F. L. SMIDTH & CO. A.S. Feb. 28, 1962 [March 1, 1961], No. 7490/61. Class 106 (2). A method of controlling and testing the degree of sintering of a sintered product depends on the fact that sintering causes increase in hardness and consequential increase in the oscillations of a shoot down which the sintered product passes or of a member projecting into the shoot. As shown, Fig. 1, the sintered product passes from the kiln 1, down a shoot 5, through a cooler 6 and down a shoot 8. A device for detecting oscillations in the form of a microphone or pick-up is attached to either shoot 5 or shoot 8 or both. The signals produced by these is used to control one or more of the following: the feed of raw material to the kiln, the fuel supply to the kiln (in a rotary kiln), the rate of rotation of the kiln, and the destination of the sintered product. The stream of sintered product which produces the oscillations may be a by-passed portion of the main stream and may have been separated into three streams according to size by screening. It may also be arranged that the stream to be tested passes a constant weight per unit time.

Filed: 1947-03-18
Abstract: 626,158. Spray producers. TRIGGS, W. W. (Homestead Valve Manufacturing Co.). March 18, 1947, No. 7491. [Class 69 (iii)] A method of producing a spray with a core of liquid slugs, for more efficient erosive action in cleaning surfaces at a distance from the nozzle, consists in discharging a spray of liquid and vapour of a liquid under pressure (i.e. steam and water), through a zone of reduced pressure (i.e. an expansion chamber), to cause a coalescence of the spray mixture into liquid slugs 14 in the discharged spray stream 15. The mixture of liquid and vapour of a liquid is conveyed by a pipe 8 to a reducing coupling 4 where it passes via an outwardly flared nozzle 12 into an expansion chamber 13 and thence to the discharge nozzle 1. A modification is shown in Fig. 2 in which the expansion chamber is formed by the annular space 20 between the outwardly flared nozzle 21 and the outer nozzle 16 which in this case is considerably longer than the outer nozzle in Fig. 1 to produce the same effect. Specification 626,159 which describes a nozzle similar to that shown in Fig. 2, but with the addition of a supply of water to the annular chamber 20 is referred to.

Abstract: Dissolvable granular porous pellets comprise a major proportion of a low hygroscopicity soluble substance as the integral porous core thereof and a minor proportion of a soluble higher hygroscopicity substance impregnated on at least the surface of the porous core. The low hygroscopicity substance may be sucrose, NaCl, KCl, KNO3, NaNO3, or tartaric acid whilst the higher hygroscopicity substance may be CaCl2, LiCl, ZnCl2, CaBr2 or glycerine.  The pellets may be of dimensions from 1/64 -1 inch but preferably 1/2 -1 inch and have a composition comprising 90-97% low hygroscopicity and 3-10% higher hygroscopicity substances.  A minor proportion of a rust inhibiting compound e.g. sodium dichromate or metallic Zn or Mg, may be incorporated; also a substance to mitigate corrosion effects e.g. trisodium phosphate.  The pellets may be made by impregnating the porous core portion with a solution of the higher hygroscopicity substance which may be done by first heating the core portion to at the most 500  DEG F.  Specific constituents for pellets are sucrose and calcium chloride; sodium chloride, calcium chloride, sodium dichromate and trisodium phosphate.  A gas, e.g. air, may be dehumidified by passage through pellets containing 90-97% NaCl and 3-10% CaCl2, whereby the moisture goes into solution with the compounds and accumulates in a sump below the pellets as a solution. Apparatus for the above process are disclosed, comprising an inlet, outlet and means for supporting pellets of the above composition.  In one embodiment, the support is shaped like the frustum of a cone and in another, a baffle is placed below two parallel flat supports.

Abstract: 453,918. Thermally-actuated valves. WALKER, C. BELL-, 38, South Bar, Banbury, Oxfordshire, and SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., Cricklewood Works, Cricklewood, London. March 16, 1935, No. 8259. [Class 135] In thermally-actuated valve apparatus comprising a main valve 14 actuated by heatresponsive means which is influenced by fluid in a conduit 32, 30, 31, 33 passing adjacent the said means and byepassing the valve 14, a pilot valve 38 controlling the byepass conduit is operated by pressure-responsive means 42 in accordance with temperature variations at a remote point. The Figure shows a valve suitable for a hot water circulating system. The lift valve 14 is opened against the pressure of a spring 15 by the compression of a bellows 23 due to the expansion of a heat-responsive liquid such as toluene in the space between the bellows and a tubular container 17. The latter has diametrically opposite external flanges 26 and is surrounded by a casing 28 so that two arcuate chambers 30, 31 are formed. These chambers communicate with the valve inlet 11 and the valve outlet 12 respectively through passages 32, 33 formed partly in a heat insulating member 19 having a bleed port 25 and a bush 20 for the valve spindle 21. A piston valve 38 in a boss 34 having arcuate slots 36, 37 controls the flow in the byepass conduit. The pilot valve 38 is closed against the pressure of a spring 48 by the compression of a bellows 42 due to the expansion of a liquid such as toluene in a closed system comprising the space between the bellows 42 and an outer container 44, a conduit 53 of narrow bore, a narrow space 55 of adjustable volume and a tubular coil 62 connected to the space 55 at 64. The space 55 is formed by a diaphragm 58 and a recessed part 56 arranged with the coil 62 in a fitting 54 having a grill 63 and an adjusting knob 59 with a pointer enabling the space 55 to be adjusted for a desired temperature. The fitting 54 is located, at a point remote from the main valve, in the compartment to be heated. The container 44 has a stop flange 52 for the bellows and may have additional thermostatic means to compensate for local temperature changes. In a modification, suitable for steam heating systems, the pilot valve is in the form of a lift valve and the chamber 30, which communicates with the inlet of the system by a separate pipe, is of substantially annular form, whilst the chamber 31 is replaced by an outlet bore in the wall of the container 17. The invention is also applicable to cooling systems. According to the Provisional Specification, heat may be supplied to the heatresponsive means by a combustible gas or liquid the supply of which is controlled in accordance with temperature changes by a pilot valve. Specification 29964/13, [Class 135], is referred to.
