Title: Liquid detector
IPC: G01N9/00
Filed: 1973-03-23
Abstract: 1415223 Detecting density changes ASAHI KASEI KOGYO KK 23 March 1973 [14 Oct 1972] 14134/73 Heading G1S [Also in Division H1]. A density change or leak detector float comprises a detector part or element of a material which responds to contact with a polluting liquid to be detected by softening, shrinkage, dissolution and/or absorption to cause a change in the apparent sp. gr. of the whole detector and operate electrical or mechanical signal means. In Fig. 1 the detector is floating on water 25 covered by an effluent layer 27 of liquid styrene or benzene. The element 1 comprising foamed styrene is dissolved by the layer 27 and causes the body 2 to sink and become inverted as shown in broken lines. A mercury switch 14 is thus operated to break contact between electrodes 16, 17 and operate a signal. The element 1 may however be of a water repellant, material so as to absorb only the liquid 27 such as heavy oil to cause the sp. gr. to become greater than 1 and the detector to sink and thus operate the signal as before. In Fig. 2 (not shown) the element 1 forms half of a full cylindrical body so that the detector body lies on its side when effluent liquid is absorbed. In Fig. 3 a perforated cylindrical housing 2,33 supports a "float" element 1 on an inner axial rod 29 so that when the housing is immersed and the element 1 is contacted by a liquid to be detected the element is dissolved or becomes heavier to lose its buoyancy and move down the rod so that a magnet 31 within the element may operate a reed switch 14. In Fig. 4 a composite block comprising the element 1 and a body 2 may float horizontally in a pool 95 so long as the pool remains unpolluted. When pollution takes place however the block 1, 2 becomes inclined and a ball 93 rolls away to operate a switch 14. The ball may however be replaced by a mercury switch or by an electrically conductive liquid and switch contacts. In Fig. 5 the detector element 1 is a floating balloon which breaks when softened and contains two electrodes, or the balloon may be replaced by a floating block. In Fig. 6 the dissolution of an element 1 either causes a float to fill and sink or fall apart or otherwise allows a switch 14 to operate. In Fig. 7 a magnet 31 is embedded in an element 1 which occupies one half of a rotatable wheel and a low sp. gr. weight 47 occupies the other lower part. When a liquid to be detected alters the sp. gr. of the element 1 the magnet rotates the wheel to occupy a lower position so that a magnetic sensor 202 when placed close to the top of the device gives no reading. As an alternative, a reed switch 14 may be operated when the magnet 31 rotates to its lower position. In a table, liquids to be detected are related to materials suitable for detector elements.

[Also in Division B1] A mobile concrete mixing unit comprises a swivel-mounted silo or bin 16, a skip 13, a weighing machine 26, a weight-indicating dial 27, an inclined track 28, 29; a mechanically operated shovel 38, a winch 21, a liquid meter 34 and a concrete mixer 25, all carried on a wheeled chassis 10. During transport the bin 16, which swivels on trunnions 17, is horizontal and rests on a support 45, as shown in dotted lines in Fig. 1. For use on site, struts 12 are lengthened by screw threaded extensions 12<1> so that the weight is taken off the chassis wheels 11 and the bin is raised to the vertical by attaching the end of a rope 22 to a strut and tie rod 19, 20 which project from the bin and winding in the rope on the winch 21. The bin is bolted to brackets 18 at the top of the struts 12. An outlet 15 from the bin 16 is then opened and cement or other fine material is discharged into the skip 13. Coarse material is heaped up at 43 against a detachable screen 42 and the shovel 38 is hauled, by a rope 37 which passes over pulleys 39, 40 and is operated by a drive member 36, so as to scoop the coarse material into the skip 13 through inlets 14. The section 28 of the track on which the skip rests during charging is supported by the weighing machine 26, whereby the weights of the added materials may be observed on the dial 27 and the mix proportioned accordingly. The end of the rope 22 is then hooked at 23 to the skip and when the mixture is proportioned as required the winch 21 is operated and draws the skip up the track. Upper and lower limit switches 30, 31 are operated so that the skip has an up and down motion, tipping at its top position to discharge into the mixer 25. A vibrator is also put into action to facilitate complete discharge into the mixer. If it is required to discharge the skip into a separate mixer, e.g. one carried on a truck, the track may be given an extension 29<1> and the rope 22 passed round a winch 21<1>. Liquid is fed into the mixer through a pipe 35, the amount being controlled by observation of the liquid meter 34.

Abstract: 1,007,606. Coke ovens. KOPPERS CO. Inc. April 13, 1962 [April 13, 1961 (2)], No. 14464/62. Heading F4B. A regeneratively heated coke oven of the compound underjet type has high and low burners 17, 18 located in each of a number of vertical flues 4 disposed alongside horizontal coking chambers 2, the flues 4 being connected in pairs by crossover flues 6 and operable alternately as " on " and " off " heating flues. The high and low burners are fed with fuel gas by separate riser channels 15, 13 respectively which are connected by pipes 26, 26a and headers 19, 19a to supply mains 22, 22a and thereby to rich fuel gas main 30. Lean gas such as blast furnace gas may be mixed with the rich gas (e.g. coke oven gas) for the high burners externally of the battery by means of branch lines 28 and valve 31. Recirculation ducts 24 connect the burners of an " off " flue to the riser channels of an " on " flue and nozzles 27 act in conjunction with Venturi sections 24<SP>1</SP> in the riser channels, as aspirating means to draw into the rising fuel gas streams a proportion of recirculated waste gases as a diluent. By this means and by the external mixing of rich and lean gases deposition of carbon in the riser passages resulting from cracking of rich gas can be avoided. The flow of gas to the burners may be controlled by valves 29 and also by the selection of suitably sized nozzle tips 27a. Combustion air is preheated in the usual way by regenerators 9 disposed below the coking ovens 2. In a modifition, Fig. 6 (not shown) recirculation ducts are provided for the high burner only.

IPC: D01D4/00
Filed: 1954-05-18
Abstract: <PICT:0761697/IV(a)/1> <PICT:0761697/IV(a)/2> An apparatus for uniformly heating melt-spinning spinnerets comprises a plate adapted to be fitted to the extrusion end portion of a melt-spinning unit for synthetic linear polymers and so constructed that walls of ducts within the plate encompass two or more filter and spinneret assemblies, the ducts being so arranged that a heating fluid can be introduced into them at two or more widely spaced locations disposed symmetrically of the assemblies and led out of them at locations intermediate of the inlet locations.  As shown in Figs. 1 and 2, a thick plate shown generally at 1 comprises a circular metal member 3 of dish-shaped formation having two circular holes 5, 7 in its mid-portion into which two filter and spinneret assemblies can be fitted.  The peripheral portion of the plate has a groove 9 machined therein, and a shallower groove 11 is machined leading out of the peripheral groove so as to join the opposite parts of the peripheral groove across the central portion of the plate between the two circular holes.  A further groove 13 of figure-of-eight formation, and of the same depth as the middle groove, is cut so as to surround the circular holes, one hole being in each loop of the figure, the groove 13 leading out of the peripheral groove at each end of the figure and merging into the middle groove at the mid-portion of the figure.  Finally the four areas 15, 17, 19, 21 of the plate surface enclosed by the grooves are machined so as to make them, in effect, very broad shallow grooves connecting the other deeper grooves.  A base plate 23, containing two circular holes identical with those of the dish-shaped plate 3, is welded across the bottom of the dish-shaped plate so as to enclose the grooves, which are thus formed into communicating ducts through which heating fluid may be circulated.  Heating fluid is led into the peripheral duct 9 through supply pipes 25, 27 let into the wall of the duct at points adjacent to the shallower middle duct 11, and leaves by outlet pipes 29, 31 let into the outer wall of the duct 9 at two points between and equispaced from the supply positions.  Specification 536,379, [Group IV], is referred to.
