    • 801,131. Controlling burners. NEWMAN, L. W., and DINE, R. May 24, 1955 [May 27, 1954], No. 15694/54. Class 75(1) An oil burner comprises a fuel nozzle I a primary air nozzle 2 and a secondary air nozzle 3, the secondary air supply being controlled by a valve (not shown) separate from the secondary air nozzle and actuated by a thermostat responsive to the temperature in the vicinity of the burner, and the fuel supply being controlled by a manual regulator 5 and by a valve 8 actuated by means responsive to the pressure of secondary air at a point between the thermostatically responsive valve and the secondary air nozzle. The fuel valve 8 slides across an orifice 7 and is connected by a spindle 17 to a flexible metal capsule 10 housed in a closed chamber 15 connected by a pipe 16 to a pipe socket 13 to which the secondary air from the thermostatically controlled valve is led. The maximum closing and opening of the fuel valve 8 are determined by set screws 24, 25. The primary air supply is not controlled by the thermostatically responsive valve and is fed by a pipe including a choke or a valve to a socket 12. The fuel, primary air and secondary air nozzles are coaxial. The secondary air nozzle is adjustable.

    • 9141. Savory, W. N. April 18. Roasting granular substances; sampling granular materials.-An apparatus for roasting malt, grain, &c. comprises a stationary casing 1 and a revolving drum 3 mounted on hollow bearings 4 carried by bearing-rollers 2 and communicating with circuitous passages 5 within the drum. The heating-medium consisting of steam, flue gases, or gaseous or liquid fuel passes in through one or both bearings, through the passages 5, circulates round the drum, is deflected downwards round the drum by an arched baffle 10, and finally escapes by the opening 11. When combustion takes place in the apparatus, the passages 5 and casing 1 are lined with fire-brick 13 or the like, and cone-shaped baffles 12 form a primary combustion chamber near the inlet and ensure complete combustion. Vapours driven off from the roasting material leave the drum by apertures 14 and are consumed in the passages 5. Conical rings 24 stir the material and prevent accumulation at the ends of the drum. The material is supplied and discharged through a lateral opening in the drum and through doors in the upper and lower parts of the casing. Samples are taken by means of a small rotary door 17, Fig. 3, carrying a pocket 22 and having a star-wheel 19 on its spindle. When the handle 21 is pressed inwards, the pins 20 engage the star - wheel, and, as the drum rotates, the door 17 is turned, and a sample is taken by the pocket and dropped into a hopper 23 discharging through the casing. The flues may be so shaped that the drum is rotated by the reaction of the heating-medium.

    • 1,069,613. Door operating devices. WILLIAM NEWMAN & SONS Ltd. Nov. 19, 1965 [March 4, 1965; Oct. 14, 1965], Nos. 9216/65 and 43544/65. Heading E2M. In a swing door assembly comprising a plurality of independently mounted swing doors, each formed of a glass panel and metal frame, and movable from an in-line position across the door opening to a staired out-of-use position at one side of the opening a spring door closer incorporating a fluid check is coupled to the top of each door and means is provided to disconnect the coupling when the panels are slid to one side to the stowed position. The doors may be coupled to the door closer in pairs. The lower pivot 19 is mounted on wheels 13 to run in a casing 14 and the upper pivot 27 is carried by a platform 21 slidable on rods 23 to the stowed position. The pivot 27 carries a plate 30 in which the coupling means is mounted, the door closer 9 being mounted along the lintel and having a depending spindle 10. To uncouple the door and its upper pivot from the closer 9 the door is swung through 90‹ to the open position when the door and its pivot 27 and the plate 30 can be slid away from a block 35 clamped around the spindle 10. A wedge plate 32 having an inclined slot 33 guided by pins 34 provides clearance once the door has started to move sideways. A latching device locks the plate 30 to ensure that the plate and the block 35 will re-engage when the doors are returned to the "in-line" position. Chains 48 along the upper and lower guideways are connected to a vertical shaft (49 Figs. 8 and 9) at the side of the door opening to ensure even running of the doors in the top and bottom guideways. The end doors adjacent the door jambs can have spring closers mounted in the floor since these doors are not slid sideways when stowed.
