Title: Improvements in or relating to furnaces
Inventor: LAUDER JOHN PATON
IPC: F23N5/08
Filed: 1963-01-22
Abstract: 992, 082. Automatic smoke control. A.B. SCORER Ltd. Jan. 22,1964 [Jan. 22, 1963], No. 2629/63. Drawings to Specification. Heading G3R. The emission of visible smoke or fumes from a furnace is prevented by automatically controlling the supply of fuel to an after-burner in dependence the density of the fumes to light or other radiation transmitted therethrough. As applied to a refuse combustion furnace, light from a lamp passes through the products of combustion in the exit flue pipe on to a photo-electric cell so that reduction in the light by the presence of smoke energizes a relay to operate a motor and thereby open a valve controlling the supply of fuel to an after-burner which may be situated at the exit of the primary combustion chamber, within a secondary combustion chamber, or in the flue itself. A shutter in the path of the light or a rheostat in the circuit of the lamp is operated simultaneously with the valve to provide follow-up. When the smoke has been cleared, a further relay operates the motorised valve in the reverse sense until smoke reappears. Continuously operating rotary switches produce intermittent operation of the valve and are arranged to cause different rates of operation in each sense, Use of two photo-cells and association of the light detector with a by-pass flue is referred to.

Title: Well completion method and system
IPC: E21B33/14
Filed: 1975-01-21
Abstract: 1501504 Wells &c G O SUMAN 21 Jan 1975 [28 Jan 1974] 2658/75 Heading E1F A method of completing a well includes the steps of positioning an inflatable packer in the borehole opposite a formation, forcing cement into the packer to expand its packing element into contact with the formation, allowing the cement to set and then making at least one perforation from the interior of the packer, through the cement and packing element to the formation. In a first embodiment a borehole 10 passes through two formations A and B. A string of casing 11 carrying packers 12, 13 is then run into the borehole 10 until the packers 12, 13 are opposite the formations A and B. Each packer 12, 13 consists of a mandrel 15, a fixed lower collar 17, a movable upper collar 16 and a resilient sleeve 18. While the packers 12, 13 are deflated the annulus between casing string 11 and borehole 10 is filled with cement 14. During the cementing operation a plug 21 is pumped down the casing 11 by additional cement on top of the plug 21, and, as it passes the packers 12, 13, the plug 21 shears plugs 20a so that cement 22 is caused to flow into the packers 12, 13 to inflate and expand them. After the cement has set, cement remaining in the casing is drilled out in conventional manner. Perforations 23 are then formed through each mandrel 15, cement 22 and sleeve 18 into the formations A and B. The perforations 23 may be formed by shaped charges or by dissolving away acid soluble plugs mounted in the packers 12, 13. In a modification (not shown) in which the borehole passes through two or more formations located adjacent each other a single packer extends across all the formations.

Title: Improvements in and connected with a method of testing electric circuit breakers
Inventor: COLEMAN EDWARD
IPC: H01H69/01
Filed: 1960-01-27
Abstract: 913,329. Testing circuit-breakers. CRABTREE & CO. Ltd., J. A. Jan. 13, 1961 [Jan. 27, 1960], No. 2903/60. Class 37. A method of adjusting an electric circuitbreaker having a trip mechanism actuated by an electromagnetically-operated plunger, includes obstructing the operation of the trip mechanism by the plunger, passing several times the rated current through the breaker, reducing the current to a little above the rated value, freeing the trip mechanism, and, after confirming that the breaker has remained in the untripped condition, adjusting it until it trips. Circuitbreakers 1, Fig. 2, mounted on jig-plates 2, are fed by conveyer 3 to actuate a pivoted arm 5 which starts a rotary timer 9, the first operation initiated by which is the clamping of the jigplate 2 in a standard position and the engagement of a pair of contacts with the circuitbreaker terminals. In timed sequence thereafter, pin 15 is passed through aligned openings in the jig-plate and circuit-breaker casing, to prevent operation of the trip mechanism by movement of the circuit-breaker's plunger; six times the rated current is fed to the circuitbreaker to cause the plunger to move rapidly to its full extent against its restraining spring; and the current is reduced to about 115% the rated current as the pin 15 is withdrawn. Normally the initial condition of the breaker before test is such that the trip mechanism now remains unactuated ; this is tested by feeding a pulse to a switch 23 which the circuit-breaker dolly 1<SP>a</SP> contacts, if it has fallen due to actuation of the trip, to energize an alarm and stop the conveyer. Otherwise, if the dolly has remained in the position of Fig. 2, screw-driver 27<SP>a</SP> is moved to engage a spring-adjusting screw of the trip mechanism, and is rotated by motor 28 until the spring allows the trip to operate. Thereafter the screw-driver is retracted, a pulse is fed to switch 24 whereby the alarm is energized if the dolly 1<SP>a</SP> is still in the untripped position, and finally the jig and breaker are unclamped and the next pair on the conveyer fed forward. All the operations are controlled by the various contacts 10 to 33 of the rotary timer 9, current from which energizes solenoids operating valves controlling the pneumatic pressure applied to the ram cylinders 12, 15, 30, and 37.

Abstract: 603,575. Light-sensitive cells. STANDARD TELEPHONES & CABLES, Ltd., RICHARDS, E. A., and PEASE, W. E. Feb. 6, 1945, No. 2967. [Class 40 (iii)] A photo-electric cell comprises a metal baseplate having a coating of light-sensitive material and a light-permeable electrically-conducting counter electrode formed as a coating on a .,first part of the surface of the light-sensitive material and conductively extended over a second part of the surface, the light-sensitive material being electrically insulated from said extension over a limited portion of said second part of the surface of the light-sensitive material. In the cell shown in Fig. 1, an insulating disc 4 is provided, co-axially with a central aperture 3, on the selenium layer 2 formed as a coating on the base-plate 1 and the counter electrode 5 is formed by a translucent conductive layer, preferably of gold, deposited by sputtering. A ring 6 of a lowmelting point alloy is sprayed on to the disc 4 and on the adjacent part of the counterelectrode 5, a suitably shaped mask being employed to prevent the alloy from spreading to the base-plate and forming a short circuit. A bolt 7 engaging the ring 6 and passing through an insulating sleeve 9 carries terminal members 11, 12 separated by an insulating washer 10. In a modified construction, Fig. 3, 4, 5 (not shown), the insulating material is formed as a narrow ring near the periphery of the disc and the alloy ring covering the insulating material is extended so as to cover a part of the counter electrode. In this construction, terminal means are provided by two peripherally-mounted metal rings in contact respectively with the base-plate and the alloy ring. If a suitably hard material is used for the counter-electrode, the alloy ring may be omitted and the counterelectrode extended over the surface of the insulating material allowing direct contact between the terminal means and the counter-electrode. Specification 526,482, [Group XXXVI], is referred to.

Abstract: 668,666. Centrifugal machines. SCHWARZ ENGINEERING CO., Inc. Feb. 6, 1950 [Feb. 14, 1949], No. 3027/50. Class 23 A centrifugal machine for removing air or other gases from liquid comprises a chamber which is maintained under vacuum and intc which the liquid is introduced, the liquid being acted on by centrifugal force and repeatedly subjected during its outward movement tc disruption into droplets. The liquids which can be treated include oil, fruit and vegetable purees and ketchup. Liquid to bE deaerated is supplied to a chamber 2, Fig. 1, by a pump 32 or by gravity through a pipe 28 which discharges it at the centre of a rotor 7. The rotor carries a number of concentric baffle plates, containing perforations of, say, # to 3/32 inch in diameter. In its outward movement, the liquid is repeatedly disrupted into small droplets by the perforations, thus facilitating the release of gas, which is withdrawn from the chamber 2, as by a vacuum pump 5. Deaerated liquid is discharged from a sump 37 through an outlet 38, over which a strainer 39 may be placed. The innermost baffle plate 24 is detachably secured to a hub 21 by a bayonet connection 23, Fig. 3. Impeller blades 36 and a flange 34 prevent liquid from clmbing over the top of baffle plate 24. The remaining baffle plates are secured in grooves 22, as by welding or brazing. In a modified rotor construction, baffle plates 57, Fig. 4, are secured in grooves 56 in the spokes 52 of a spider 49 which is detachably mounted on a rotor plate 41 with the spokes 52 seating in radial grooves 46, Fig. 6. Annular grooves 48 align with the grooves 56 and receive the portions of baffle plates 57 lying between the spokes 52. As before, the innermost baffle plate has a bayonet connection with the rotor hub. Climbing of the liquid is prevented by a lip 61 and a conical deflector 62, but the means shown in Fig. 3 may be used instead. In a further modification, the rotor plate is eliminated, and the spider is secured to the rotor hub. In place of concentric plates, the baffle means may be of spiral form.
