Title: A Measuring Body for Use in High Temperature Furnaces.
Inventor: KRUSENSTIERNA OTTO VON
IPC: G01K3/00
Filed: 1967-10-04
Abstract: 1,195,110. Selective signalling. ALLMANNA SVENSKA ELEKTRISKA A.B. 4 Oct., 1967 [5 Oct., 1966], No. 45189/67. Heading G4H. [Also in Divisions F4 and H1] Apparatus for use in making measurements of wall thickness and/or melt temperature in a high temperature furnace comprises a flat elongated body of refractory material having a plurality of metallic conductors extending therein to different distances from one narrow end of the body. As shown in Fig. 5 the body comprises a plurality of thermocouples extending to different distances from one end and as shown in Fig. 10 the body is inserted between adjacent bricks of the furnace lining, the end from which the conductors emerge being thickened to make a heel 12 which facilitates its mounting in the furnace. By measuring the temperature indicated by each thermocouple an extrapolated figure corresponding to the temperature within the furnace may be obtained. As the furnace wall wears away in use, the inner end of the body also wears away thus exposing successive thermoelectric elements; these are short circuited by the conductive melt so providing an estimate of the remaining wall thickness. If a wall thickness measurement alone is required the thermocouples may be replaced by single isolated electrical conductors extending for different distances through the body, Fig. 6 (not shown). The body may be made of alumina and the conductors therein may be given a wave, spiral or zig-zag shape to prevent breakage due to thermal expansion. This risk may be further reduced by surrounding each conductor within the body by a soft insulating material. Thermocouple materials may be various platinum-rhodium alloys. Shapes other than rectangular are proposed for the body of refractory material.

Title: Movement detection system
IPC: H04N11/00
Filed: 1970-09-24
Abstract: 1328355 Movement detection system INTERNATIONAL STANDARD ELECTRIC CORP 24 Sept 1970 [29 Sept 1969] 45506/70 Heading H4F [Also in Divisions G2 and G4] In a movement detection system the "twocolour" or "Land" colour reproduction principle is utilized, and in a first embodiment the image of the scene being viewed is directed via dichroic mirror 36 and red and green filters 38 and 42 on to television cameras 32 and 34 respectively. The video signals from the cameras are fed directly and via a storage device 56, e.g. a video tape recorder, to television displays 44 and 52 which are viewed via red and green filters 46 and 54 and dichroic mirror 48. In use, if an object in the scene moves from a first position to a second position it will be observed for the duration of the delay of storage device 56 as a "red" object at the first position and a "green" object at the second position (these colours will of course be modified by the colour of the scene which is behind the object in its two positions as televised by the other camera). When the stored picture "catches up" with the instantaneous picture the object is viewed in its natural colour. In a second embodiment, Fig. 5, a single gun display CRT 116 is used of the type containing a phosphor screen which changes colour as the current density is changed. The video signals from cameras 102 and 106 having green 104 and orange 108 filters are supplied directly and via storage device 114 to a video switch 112 which directs alternate fields (interlaced scanning) of each signal to the display tube 116. Simultaneously the grid and thus the bias of tube 116 is switched 124 from a low current density wherein the tube produces a colour having a wavelength similar to filter 104 to a higher current density having a wavelength similar to filter 108. A single camera tube may be used having a mechanical colour filter changer which alternately places filters 104 and 108 in front of its lens. Two guns of a conventional three-gun colour television camera together with the corresponding two guns of a conventional three-gun receiver may be used. A photographic embodiment is referred to in which a scene is recorded on two still slides taken at different times via different colour filters, the images from these slides being superimposed using appropriately coloured light. Only one of the superimposed television or slide images need be displayed in a colour, and this colour need not be the colour used during the pickup or recording thereof.

Filed: 1963-11-20
Abstract: 1,008,296. Centrifugal pumps. H YOKOTA and S. YOKOTA. Nov. 20, 1963 [Nov. 20, 1962, March 23, 1963], No. 45756/63. Heading F1C. A pump, particularly for mud-like fluids of high viscosity and containing large amounts of air, comprises a main centrifugal pump A, Fig. 1, having an inlet 3 and an outlet 4, an auxiliary centrifugal pump B having an inlet 13 connected with the central area of the main pump chamber and an outlet (not shown) connected, as through a passage 7, with the inlet 3 of the main pump, the auxiliary pump inlet 13 being throttled in relation to the pumping capacity of the auxiliary pump, and vacuum creating means having an inlet communicating, as through passage 16, with the central area of the auxiliary pump chamber. The vacuum creating means is a pump 18 driven by a shaft 10 common to main and auxiliary pump impellers 9 and 14 respectively. The inlet 13 may be formed by parts of combined hard material and rubber or having teeth which crush any foreign matter and fibrous materials, and is tapered to prevent clogging with foreign matter. The pump is inially primed by running it with the outlet 4 closed and air is withdrawn by the vacuum pump 18 through passage 7, the auxiliary pump chamber, passage 16 and a passage 17, and also through the inlet 13, concentric or eccentric and staggered openings (not shown) in the central portion of the auxiliary pump impeller 14 and passages 16, 17. During pumping of the mud-like fluid, air is withdrawn by the vacuum pump 18 by way of the inlet 13, the air-free mud-like fluid being returned through the passage 7 to the main pump inlet 3 by the auxiliary pump B. Some of the air is separated from the mud-like fluid in the auxiliary pump impeller 14 by centrifugal action and the impeller 14 may have two plates to improve the separation. In a modified arrangement, Fig. 5, a slit 12 through the back plate of the main pump impeller is formed behind each blade 11, the radially inner end of each slit 12 being in continuous communication through the inlet 13 with the low pressure created by the vacuum pump, thereby decreasing cavitation. Additionally, a check valve, Fig. 8 (not shown), is mounted on the casing between the passages 16 and 17, the valve being controlled by a spring-biased diaphragm, bellows or piston in accordance with the pressure differential between atmospheric pressure and the pressure created by the vacuum pump. This is particularly suitable where the level of the fluid being pumped is higher than that of the pump, so that when the latter is stationary the valve closes thereby preventing the mud-like fluid from reaching the vacuum pump. Alternatively, the passage 16 may be provided with a floatcontrolled valve. The passage 17 may have a sump with a check valve at the bottom for disposal of any leakage fluid.
