IPC: F23N5/08
Filed: 1960-03-22
Abstract: 976,621. Controlling burners. BABCOCK & WILCOX Ltd. March 22, 1961 [March 23, 1960], No. 10044/60. Heading F4T. [Also in Division G1] Apparatus for monitoring a flame in a combustion space comprises a photo-cell and means responsive to fluctuations in the output thereof having a frequency above the natural frequency of radiation fluctuations in the combustion space. The high-frequency fluctuation are said to emanate mainly from the zone of initial combustion and their detection facilititates distinction of closely adjacent flames. In a burner to be monitored, pulverized coal and air pass along pipe 1, impinge on a diffuser 9 and produce a flame front at 28, which is viewed by a photo-resistance in the container 33. Coaxial with pipe 1 is a tube 2 containing an atomized oil lighting-up burner 23 and a light path for a further photo-resistance 63 which views the flame front 29 of burner 23. The photo-resistance 30 is connected in a circuit 49, Fig. 5, described in Specification 976,622 which delivers D.C. outputs 277, 50 respectively indicative of the mean illumination of the photo-resistance 30 and the ratio of the fluctuations of illumination to the mean illumination. The relays 66, 67, 69, 70 determine whether these outputs are shown above or below relatively high and relatively low levels and relay 71 determines whether the mean output of photo-resistance 63 is above or below a given value. Various combinations of the outputs of these relays and the detectors 72, 74 which detect whether or not oil and coal are being supplied to the respective burners, cause a selective relay to energize various combinations of the lamps 81-86 to show the condition of the burner. Meters 88, 89 may also indicate outputs 50, 277.

Title: Breaking device for an openend or break-spinning unit
IPC: D01H4/12
Filed: 1972-03-03
Abstract: 1348592 Brake spinner WILHELM STAHLECKER GmbH 3 March 1972 [3 March 1971] 10079/72 Heading DID The spinning rotor 2 of a reduced pressure break spinning unit is braked either by opening an openable part 1 of the housing or by actuating the brake 12 without opening the housing. Preferably openable part 1 contains the means for feeding and opening a sliver. As shown in Figs. 1, 2 belt 4, which may drive several rotors, is pressed against rotor axle 5 by roller 6. Roller 6 is mounted on lever 8 which swivels about pivot 9 and is held in its operative position by the tension of spring 24, transmitted by flexible band 16. On moving brake operating lever 19 counter-clockwise, either directly or by swinging open housing part 1 the tension is removed from band 16, thus allowing spring 15 to rotate lever 8. Belt 4 no longer contacts axle 5, instead brake surface 12 is pressed against the axle by the action of projection 10 of lever 8 on leaf spring 11. In the embodiment of (Fig. 3, not shown) transmission band (56) is tensioned by spring (62) which presses operating lever (59) against an adjustable stopping screw (60). Tension is released by pivoting lever (59) or by swinging open the housing, thereby moving band guide pulley 57 so as to release the tension. In the embodiment of (Fig. 4, not shown) pressing roller 6 is held in position by a spring, and transmission band (84) is tensioned by forming a vee in the band between a guide roller (90) and rods (87, 88) when braking is required.  In the embodiment of (Fig. 5, not shown) roller 6 is held in its pressing position by the tension in transmission band (97). The tension is released by a pivoting brake operating lever (104) so as to press upwards abutment (102) on band (97), or by pivoting part 1 of the housing, thereby pressing upwards a second abutment (103) on band (97). In the embodiment of (Fig. 6, not shown) the spring 15 which tends to urge brake 12 against axle 5 is opposed by torsion spring (129) the force being transmitted directly by bell cranked brake operating lever (125), there being no transmission belt. In the embodiment of Fig. 7 compression spring 175 causes operating lever 168 to force drive belt 4 against rotor axle 5 via presser roller 6. The drive is disconnected by pulling handle 172 downwards or by opening housing part 173 by rotation about horizontal axle 20. Alternatively housing part 173 may swing about vertical axle 174.
