Title: Blower type cleaning for heat exchanging apparatus
Inventor: CANTIERI WILLIAM FRANCIS
IPC: F22B37/56
Filed: 1962-09-21
Abstract: 1,022,254. Soot blowers. DIAMOND POWER SPECIALTY CORPORATION. Sept. 21, 1962, No. 35966/62. Heading F2N. Remotely actuable, multiple soot blowers are operated automatically in sequence in heat exchange apparatus according to the cleanliness of the heat absorption surfaces as indicated by means which sense the temperature of the final steam and energize or de-energize a control system which operates the soot blowers in a pre-selected cycle. A typical boiler (Fig. 1, not shown) has short-travel wall blowers for its steam generating section and long-travel blowers for its superheater bundles. The reheater and air heater may also have blowers operating in the cycles. The blowers (Fig. 5, part) are of known type comprising a lance 46, normally retracted, but driven out through a hole 48 in the boiler wall 50 by an electric motor 40 to eject steam, air, or a mixture of both on to the boiler tubes as required. Temperatures at the superheater or reheater steam outlets are sensed by a thermocouple, bulb pyrometer or resistance thermometer (Fig. 2, not shown) which electrically operates a transducer to vary the air-pressure controlling a steam temperature compensating mechanism which mechanism uses known methods of control, such as tilting the burners (Fig. 3, not shown), damper control to regulate flue-gas recirculation, or surface or direct-contact attemperators. At the same time, or when the compensation has reached a preselected rate, the same air pressure variation operates directly or indirectly a switch to energize the blowers. To avoid large temperature fluctuations when the blowers are operated, a delay is allowed between the operation of the blowers in the steam generating section and the blowers in the steam heating section; simultaneous operation of the blowers in the two groups being prevented by an interlock. The frequency of operation of each group within its own cycle is controlled between maximum and minimum limits by a timer device. A device which is described in Specification 1,022,255, divided from the present Specification, senses the thickness of slag in the boiler tubes and, when it is excessive, produces signals which over-ride the cycle of the second group of blowers and operate them until the slag thickness is reduced to a predetermined level.

Abstract: 1,006,348. Stretching polyamide filaments. INVENTA A.G. FUR FORSCHUNG UND PATENTVERWERTUNG. Oct. 12, 1961 [Oct. 21, 1960], No. 36673/61. Heading B5B. In a process for stretching a filament of linear polyamide the filament is fed off a leadin roller and is drawn on to a take-off roller rotating at a greater peripheral velocity, and the filament, while passing from the lead-in roller to the take-off roller, is passed around such a peripheral length of a heated stationary roll having an uneven surface of such a nature that the filament is first cold-stretched, is heated and is then hot-stretched. A rotatable guide roller around which the filament is guided may be arranged parallel to the heated roll so that the filament is not in contact with the entire periphery of the heating roll, the position of the guide roller being adjustable relative to the heated roll. The heated roll is suitably held at 115 C. The surface of the heated roll may be provided with pores by roughening, e.g. by sand-blasting and subsequent polishing or by matt chromium plating, or may be grooved or fluted, the grooves or fluting being parallel to the axis of the roll. Cold-stretching occurring before the filament is heated may be 1 : 3, and hot-stretching 1 : 1À7. Apparatus as shown comprises a rotating leadin roller 2 and associated guide roller 3, round which the filament 1 passes three or four times, stationary heating roll 4 and rotatable guide roller 5, round which the filament passes two or three times, and a rotating take-off roller 6 and associated guide roller 7, round which the filament passes several times. The zone between members 2 and 4 is thus a cold-stretching zone, and that between members 4 and 6 is a hot-stretching zone. Specification 806,532 is referred to.
