Title: Improvements in or relating to means for detecting the presence of impurity in a liquid
Inventor: BEALE ALBERT
IPC: G01N19/10
Filed: 1954-11-11
Abstract: <PICT:0805004/III/1> Apparatus for detecting the presence of impurity in a liquid comprises a solid medium over or through which the liquid is caused to flow and means operated by a physical change in the medium induced by the impurity but not by the pure liquid to stop the flow of liquid or operate an alarm signal.  In the case of a liquid impurity such as water in petrol or other liquid fuel, the medium may consist of fibrous, cellular or porous cellulose material which swells in the presence of water.  In Fig. 1, a pile 7 of annular lamin  of such material is supported on a plate 6 fixed to a rod 5 arranged in a casing 1 having an inlet 2 and an outlet 3.  The rod 5 is secured to the top portion 4 of the casing and loosely supports a spring 12 and a valve plate 8 which co-operates with a seat 9 to reduce or cut off the liquid flow when the pile 7 swells due to the presence of an impurity.  After the valve 8 has closed the device acts as an edge filter and liquid passes to the outlet 3 through an annular passage 10.  In a modification, the inlet and outlet are at right angles to the axis of the pile 7 and an additional spring is provided to cushion the opening movement of the valve.  In Fig. 3, the main flow is through a conduit 33 having a by-pass 34, 36 in which is located a pack of lamin  39 encircling a rod 38 bearing valves 37, 40 at its opposite ends.  The valve 37 is pressed towards a seat 41, Fig. 4, by a spring 43 abutting the seat and a collar 42 on the rod 38.  The valve 40 is pressed away from a seat 47, Fig. 5, which also forms an abutment for the lamin  39 by a spring 49. Due to a venturi throat 35, flow through the by-pass induces a reduced pressure in a pipe 51 connected to a spring-loaded bellows 52 operating a butterfly valve 57 in the main conduit 33.  When the lamin  39 detect any impurity they move a recessed disc 46 which through the collar 42 operates the rod 38 to close the valve 40 and so create a rise of pressure in the by-pass.  This acts on the bellows 52 to close the main valve 57.  The bellows 52 may be connected to a visible or audible warning device.  The valve 37 closes the by-pass 34, 36 and hence the valve 57 in the absence of the lamin  39.  The device may be used upstream of a main filter to protect the latter from contamination by water or it may be used downstream of a water-eliminating main filter to detect the passage of water therethrough.  According to the Provisional Specification the valve instead of being operated directly may be operated through linkwork or a relay.  It may control the inlet instead of the outlet. The signal device may be operated by a diaphragm responsive to the fall of pressure in the outlet or the rise of pressure in the inlet when the main valve closes. Specification 682,400, [Group I], is referred to.

Title: Improvements in and relating to methods of and apparatus for producing refractory bodies
IPC: C03B19/01
Filed: 1933-11-28
Abstract: 410,033. Fusing and working silica. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Ellis, A. L. ; 11, Banks Road, Swampscott, and Winckler, G. A. F. ; 29, Clearview Avenue, Worcester, both in Massachusetts, U.S.A.) Nov. 28, 1933, No. 33335. Convention date, Nov. 30, 1932. [Class 56.] Relates to the apparatus described in Specification 364,993 for producing massive articles of refractory material, particularly for forming a silica blank for an astronomical mirror. The present invention consists of means for regulating the rate of feed of the comminuted silica, means for protecting the gas conduits from the abrading action of the silica, means for distributing the silica in the fusion zone, and means for conserving the heat of the fusion zone. The article which is being built up, such as a blank for an astronomical mirror, is contained in an electrically heated furnace consisting of a housing 55, Fig. 1, having resistance heaters 59, 60 on the walls and roof and below the silica blank 61. The burner 58, which deposits the silica, is carried by a support 57 that passes through openings in the housing 55 and rests on rollers 62, 63, 64. The support is a tube through which water or other cooling fluid is circulated, and it encloses the gas supply conduits 65, 66, Fig. 2. An offset joint 67, into which silica becomes packed, is provided at the bend of the conduit 66 and acts as a wear-resisting deflector for the silica powder carried by the stream of hydrogen. The burner 58 is moved to-and-fro over the blank 61 by any suitable mechanism 76, Fig. 1. The burner, as described in the earlier Specification, comprises two groups or bundles of tubes 78 supplied with oxygen and hydrogen respectively. The groups of tubes approach one another at their outlets to prevent concentration of silica near the outer zone of the burner. Deflectors 79, secured to the burner, prevent the silica from depositing in ridges. The device for feeding the silica consists of a drum 85, Fig. 6, having a number of small pockets 86 formed on its surface, and these pockets become filled with the finely divided silica as the drum rotates past a hopper 83. The silica falls from the pockets into the hydrogen conduit, and the rate of feed of the silica is independent of the velocity of the gas stream and the condition of the silica itself. The heat deflector for the fusion zone consists of a conical member 93, Fig. 7, supported by hangers 94 from the flange 96 of the burner jacket 71. The deflector is supported at some distance below the orifices of the burner, but close to the heated area of the article which is being built up.
