Title: Improvements in or relating to apparatus for mixing a liquid with a liquid or a gas
Inventor: LIGHTOWLER LESLIE ERNEST
IPC: B01F5/04
Filed: 1951-10-12
Abstract: 702,964. Mixing fluids in flow. LAYCOCK ENGINEERING, Ltd. May 12, 1952 [Oct. 12, 1950]. No. 23773/51. Class 86 An apparatus for mixing an added liquid with a liquid or gas comprises an inlet for the admission of pressure liquid or gas, an outlet for the mixture and a passage connecting the inlet and outlet containing a mixing ejector to receive the pressure liquid or gas from the inlet, a main chamber which communicates with the outlet having a flexible member separating it from an auxiliary chamber for added liquid, so that the flexible member may be distorted by the pressure liquid or gas to eject added liquid from the auxiliary chamber to the mixing ejector. As described, liquid to be mixed with pressure liquid or gas is supplied, by means of a hand operated pump 16, through a filter 11 and non-return valve 23, into a chamber 1 which contains a flexible diaphragm 24 which is forced to conform to the interior of the half 3 of the chamber 1 as the chamber is filled with liquid from the pump 16. In a mixing operation, pressure gas or liquid is introduced at an inlet 43 and passes through a mixing ejector in a chamber 41 and leaves the apparatus mixed with the added liquid through an outlet 50, from which a passage 51 opens into the half 3 of the chamber 1. Pressure liquid or gas entering the chamber 1 through the passage 51 places the liquid on the other side of the diaphragm 24 at the pressure of the pressure liquid or gas, at which pressure this liquid passes through a passage 28, needle valve 29 and passages 35 and 39 to a fine mixing tube 48 which opens into a mixing bore 47 in the mixing ejector through which the pressure liquid or gas is flowing, whereby a very small and substantially constant addition of added liquid in pressure liquid or gas is obtained. The needle valve 29 may be closed by a control knob 33 to cut off the added liquid when plain liquid is to be supplied. The flexible diaphragm is made of material resistant to attack by the liquids or gases used, and if the added liquid is of greasy or oily character, suitably resistant rubber or synthetic rubber may be used. The apparatus may be used for adding soap, detergent or disinfectant to pressure liquid or insecticide to pressure liquid or air for spraying fruit trees or the like.

Title: Plugging of wells
IPC: E21B47/09
Filed: 1976-06-09
Abstract: 1529615 Wells &c D C CAMPBELL 9 June 1976 [9 June 1975] 23916/76 Heading E1F [Also in Division G1] A potential producing formation 14 of known extent and elevation in a well bore 12 e.g. an abandoned dry well, is plugged with cement by a method including the steps of positioning a drill pipe 10 at a selected location relative to the lower level of the formation, injecting cement through the pipe 10 in an amount estimated to be sufficient so that it extends at least the full length of the formation to prevent seepage from the formation after the pipe 10 has been withdrawn and the cement has hardened, a selected portion of the cement containing a radioactive tracer and being injected so as to provide a layer of cement 16 containing the tracer at the top of the wet cement plug, withdrawing the pipe 10 from the wet cement lowering into the well bore 12 a detecting means e.g. scintillation counter, sensitive to and emitting an output in response to the presence of the tracer, and determining the elevation of the top of the wet cement plug by analysing the output of the detecting means. If the level of the top of the plug is too low, further cement, part containing tracer, may be added and detected as above. Once the lowermost formation in the well has been plugged in this manner, so may the remaining potential producing formations be plugged, the regions between the plugs being filled with drilling fluid or mud. The method allows the level of the top of a plug to be determined without waiting for the cement to dry. The cement containing the tracer, e.g. an iridium-192 radioactive sand tracer, is preferably injected in two parts, one part being injected first followed by untreated cement to displace the one part upwardly to form a ring A, the other part being injected last so that it is located within the pipe 10 at B, the pipe being withdrawn to allow the two parts to flow together or one to flow over the other if there is a difference in levels at the end of the injection. Preferably the output of the detecting means is is recorded on a chart which is moved in synchronism with the detecting means as it is lowered in the well bore.

Filed: 1948-09-17
Abstract: 672,882. Grinding valve seats into seatings. CREDOWAN, Ltd., EDWARDS, A. H., and KINGSBOURNE PRODUCTS, Ltd. Sept. 7, 1949 [Sept. 17, 1948], No. 24482/48. Class 60. A tool particularly for grinding-in valve seatings comprises a tool-carrying member 7a, Fig. 2, oscillated by a shaft 7 that is driven by a rotating shaft 6 through the intermediary of an oscillating member 16 provided with at least one slot 15 in which are received pins 10, 13 connected to the co-axially-arranged shafts 6, 7. The shaft 6 has disc 9 carrying the pin 10 and a roller 11 offset at a greater distance from the axis of the shaft than the pin 13 and its roller 14 so as to permit the roller 11 to slide in the slot 15 as the shaft 6 is rotated by a chuck. During rotation of this shaft the lever 16 is swung about a pivot 17, which is fixed between a housing 1 and a top part 4 thereof, by the roller 11 traversing the slot 15, and, by co-operation between the slot and roller 14, the shaft 7 is caused to oscillate a bit, or suction-cup 8 of rubber, in engagement with the valve. If the body 1 is not held against rotation, the net force on the pivot 17 for each revolution of the shaft 6 causes the body to rotate through a small angle and so vary the position of the valve in its seating. In a modification, Fig. 3, the oscillating member 24 is guided for rectilinear motion relative to the housing 1 by pins projecting from the housing and engaging diametrically - opposite slots formed in the member 24 transversely to a slot 25 therein which passes between their adjacent ends. Rotary motion of the shaft 6 causes an eccentric pin 10 on the end thereof to slide in the slot 25 and actuate the member 24 which oscillates a pin 14 on an arm 12b secured to the shaft 7.

Title: Electrical sensing device for spring winding machines
IPC: B21F3/00
Filed: 1963-06-20
Abstract: 1,046,107. Making springs; shearing. K. HACK, [trading as MASCHINENFABRIK KARL HACK KOMM.-GES.]. June 20, 1963 [June 20, 1962], No. 24498/63. Headings B3A, B3E and B3W. An electric sensing device, for a spring coiling machine making coil springs having an eye lying in a plane which is axial to the spring windings, comprises two contacts arranged diametrally of the spring axis and each at the same distance along the spring axis from the bending point, so that when the spring has reached a predetermined length the contacts are bridged by the spring eye. The contacts 12 and 13 consist of two thin metal strips held in a carrier 11 of insulating material which has a conical bore 11a in one end. The end surfaces of the strips are flush with the surface of the bore. The wire 7 is fed by rollers 6 against bending tools 8 which form the wire into a spring 9. At the beginning of the coiling operation an eye 10 is formed and as the coiling proceeds this eye approaches the contact carrier 11. When the spring is the correct length and the eye is in the desired angular relationship to the bending tools, the contacts 11 and 12 are bridged and as a result the current to an electro - magnet 5 is interrupted and a spring 15 disengages a clutch 4 in the drive to the feed rolls 6. The wire is cut by a knife 16. In a modification the upper feed roller is lifted to stop the feed when the electromagnet is de-energized. In a further modification a second sensing device reduces the feed speed when the spring reaches a predetermined length which is less than the finished length, so that the final portion of the spring is wound at a very low speed to increase the accuracy of the final spring length.
