Title: Improvements in method and apparatus for cleaning gas-swept heating surfaces with cleaning elements such as steel pellets or the like
IPC: F23J3/02
Filed: 1954-01-21
Abstract: 753,851. Cleaning tubes. AKTIEBOLAGET A. EKSTROMS MASKINAFFAR. Jan. 21 1954 [Feb. 2, 1953], No. 1860/54. Class 99(2). In cleaning gas swept heating surfaces in boilers, superheaters, air preheaters, economisers and the like cleaning elements e.g. steel pellets or the like are periodically distributed over the heating surfaces and are projected against the latter to remove dust deposits and coatings adhering thereto whereafter the cleaning elements are returned to a position from which they may be redistributed by means of a gaseous fluid for example cool air and the return of the cleaning elements is effected continuously or for periods of time which are substantially longer than the cleaning periods in order to reduce the dimensions and the power requirements of the conveying means and to attain an intense bombardment of the heating surfaces with the bulk of the cleaning elements which have been returned since the preceding cleaning period. in application to a boiler 10, Fig. 3, cleaning pellets are supplied from a single cyclone device 11<SP>1</SP> through distributing conduits 12<SP>1</SP>. Two pockets 17<SP>1</SP> are associated with a single return conduit 14<SP>1</SP>. Cleaning takes place during a comparatively short time. The return fan 16 is however in operation either continuously or for periods of time which are considerably longer than the actual cleaning periods. As an example it is stated that a single fan will convey the pellets in 7 hours but these may be released in one hour. A valve (not shown) for release of the pellets, is provided below the device 11<SP>1</SP>, Deflecting members 13 and separators 18 are provided. The capacity of the cyclone device is sufficient for receiving essentially the whole quantity of cleaning elements. Fig. 1 shows a known cleaning installation comprising three cyclone devices 11 and three fans 16 and associated return conduits.

Abstract: 1509822 Relay matrix INTERNATIONAL STANDARD ELECTRIC CORP 20 Jan 1976 [30 Jan 1975] 02143/76 Heading H4K In a matrix ofbi-stable relays, each relay has two control windings and is operated by coincident bipolar current pulses in the two windings. The pulses are supplied from pulse generators 5 and 6, (Fig. 1) via selectively operable switches IC and IR respective to each row and column of the matrix. Fig. 3 shows the pulses generated by generators 5 (Ix) and 6 (Iy) and their sum (IF). The pulses are such that when only Ix or only Iy is applied to a relay the relay releases, first stable state, and when both are applied the resultant pulse IF operates the relay, second stable state; alternatively the pulses may enable all the pulsed relays to release before the relay which receives pulses from both generators operates (Fig. 5, not shown) or the pulses may have decreasing amplitudes to produce more thorough demagnetization (Fig. 6, not shown) or the positive going pulses may be made wider than the negative going pulses to allow for differences in propagation times (Fig. 7, not shown). If non resonant relay contacts are used, the coils may be wound on a magnet (Fig. 8, not shown).

Title: Improvements relating to liquid spring shock absorbers
IPC: F16F5/00
Filed: 1953-01-26
Abstract: 733,006. Liquid springs. DOWTY EQUIPMENT, Ltd., and SAVERY, R. March 24, 1954 [Jan. 26, 1953], No. 2212/53. Class 108 (3). A liquid spring comprises a first plunger 8 which is movable in thrust into a pressure vessel 3 independently of a second plunger 11 to compress the liquid, the plunger 11 being movable in engagement with the plunger 8 when tension is applied to the latter to compress the liquid. The plunger 11 has an effective area which is greater than the area of the plunger 8. The plunger 11 is of stepped formation and normally seats on a step 4 in the wall of the vessel 3. The vessel at this point is vented to atmosphere by a passage 17. The plunger 11 has packing rings 15, 16, each of which comprise an 0- ring of synthetic rubber material backed up on opposite sides by anti-extrusion rings of a harder synthetic material. The gland 7 of the plunger 8 is of the construction described in Specification 539,966, [Group XXVI]. Dashpot action is provided by orifices 18, 19. In an alternative construction, the plunger 11 is replaced by a plunger of greater area than the plunger 8, passing through a closure plug formed in the lower end of the vessel 3. There is lost motion between the two plungers, so that the plunger 8 can be driven under thrust into the vessel 3 independently of the second plunger. On tension being applied to the plunger 8, it picks up the second plunger, and thus again compresses the liquid. According to the Provisional Specification, in the latter construction, the plunger 8 may be tubular and may have a radially inwardly projecting lug which co-operates with a projecting stem on the second plunger to provide the lost motion.

A stop-mechanism for an I.C. engine to operate should the drive to a cooling fan fail comprises a centrifugally-operated servo control valve 6 driven by the fan shaft 2 and controlling the flow of motive fluid from a pump 15 to a hydraulic actuator 17 connected to means for stopping the engine, arranged such that should the speed of the shaft approach zero the valve 6 will permit pressure fluid to pass to the hydraulic actuator to cause the engine to stop. The servo valve housing 3 rotates with the fan shaft, which is driven by a belt 21 from the engine, and has a radially directed bore 5 accommodating a cylindrical sliding closure member 6. The closure member 6 is spring-loaded such that when the shaft is stationary an inlet port 7 connects via passages 8 with an outlet 11. The outlet 11 communicates via a conduit 16 with a hydraulic actuator comprising a fixed piston 19 and a moving cylinder 17 connected to the fuel injector pump. When the shaft 2 is rotating the valve closure member 6 is forced outwardly to blank off the outlet port 11. Should the fan belt 21 fail, however, the shaft 2 will come to rest and the valve closure member 6 will move under its spring bias to the position shown in the Figure. Pressure fluid will then pass to the hydraulic actuator to cause it to shut-off the fuel injection pump and stop the engine.

Abstract: 673,650. Pulsing carrier frequencies; superregenerative circuits. POCOCK, A. G. Jan. 31, 1950 [Jan. 31, 1949], No. 2636/49. Class 40 (v). A squegging oscillator has a primary grid-leak resistor and a lower-valued secondary grid-leak resistor, the latter being connected in series with a unilateral conducting device whose anode is negative with respect to the lower end of the primary resistor. The oscillator shown is quenched as a result of grid current charging the blocking capacitors 6 and 6a and so reducing the grid voltage as indicated by FG. The capacitors then discharge rapidly through a diode 26 or similar device, a low resistor 7b, and, if provided, a resistor 7a until at point I the grid voltage becomes less than the negative bias voltage - Y applied to the anode 26b of the diode when the discharge continues at a slower rate through a resistor 7, as indicated at IF. If the bias voltage - Y is increased, the amplitude of portion HGI of the curve remains constant but the separation of level - Y from the oscillation commencement level - X increases and the portion IF of the curve becomes longer. The quench frequency may therefore be modulated (e.g. with a sine or saw-tooth wave) or varied by modulating or adjusting the diode bias voltage. An alternative circuit, Fig. 5 (not shown), uses a push-pull oscillator.
