摘要： 686,005. Air distributers. STEWART, I. M. HAY, Sir D. A., BLACKWOOD, D. D., (Representatives of STEWART, Sir F. C.). Dec. 1, 1950 [Dec. 1, 1949], No. 30835/49. Class 137 An air distributer device comprises a dished diffuser plate 1 with a central aperture, a deflector plate 4 formed with an aperture 5 and spaced from the diffuser plate and at least one shutter 6 pivoted to the deflector plate across the aperture 5, the reflector plate being so attached to the diffuser plate that the deflector plate as a whole is angularly adjustable relatively to the diffuser plate about an axis transverse to the axis of the shutter. The diffuser plate 1 is connected by a neck 2 to an air duct 3. The deflector plate 4 is attached by means of a spider 11 to a spindle 9 passing through a sleeve 10 fixed to the neck 2, Several independently movable shutters may be used, or the shutters may be arranged in sets, each of which is movable in unison, as shown. The deflector plate may be axially adjusted towards and away from the diffuser plate, may be rotatable about its own axis relatively to the diffuser, and may be located in desired positions by a spring-loaded ball. In another embodiment the spindle 9 is connected by a cross-bar to the plate 4 in which is mounted two semi-circular shutters. With the shutters open the air flows outwardly normal to the plane of plate 4, with the shutters fully closed the air strikes plate 4 and leaves the device in a direction substantially parallel to the plane of plate 4, and in intermediate positions of the shutters air is deflected at a corresponding angle. When the device includes more than one set of shutters air may be directed in several directions at once.

摘要： 675,284. Cargo ships. STEWART, I. M., HAY, Sir D. A., and BLACKWOOD, D. D., (Representatives of STEWART, Sir F. C.). March 22, 1950 [March 24, 1949], No. 8024/49. Class 113 (ii). [Also in Group XIII] A metallic ship structure is provided with an automatic control of the effective heat output of a heating means H which is applied to a wall, bulkhead W, floor or ceiling in an unrefrigerated space R adjoining a refrigerated cargo space P to maintain the bulkhead or the like above the dew point in the space R and prevent the formation of condensation. The heating means may comprise electrically heated cables or elements in a metal sheath, Fig. 2 (not shown), or a metal pipe H welded to the bulkhead W close to where it joins the deck D and through which pipe passes a fluid, such as sea water heated if necessary. Thermostats, humidistats or dew point sensitive instruments control the temperature, or flow, of the fluid or the electrical supply for the heating means. Since heating of the atmosphere of the space R is undesirable, the heating means is insulated therefrom.

摘要： 726,798. Drying apparatus. STEWART, I. M., BOBY, Ltd., R., and WESSON, J. P. July 28, 1953 [July 28, 1952], No. 18974/52. Class 34 (2). [Also in Group VI] In malting and drying apparatus, of the type including a rotatable cylindrical drum 1 with a perforated grain floor 2 and means for creating a difference in pressure between an air inlet and an air outlet to pass air through the grain, the air inlet and outlet are both at one end of the drum. In one construction, a bulkhead 3 terminating at the floor 2 is provided in the drum and is joined to the end 4 by a partition 5 having an extension 5a, which divides a cylindrical axial duct 7 penetrating the end 4 into two passages, one of which leads to a side port 8 communicating with a stationary air duct 9. The other passage has an axial port 10 admitting a stationary air duct 11. The floor 2 extends from the other end of the drum as far as the bulkhead which, beyond the partition, is provided with perforations 6. Seals 12 are provided so that the drum can be rotated without disconnecting the ducts 9 and 11. Air may flow through the apparatus in the direction indicated by arrows or in the opposite direction. In another construction, the partition extends longitudinally between the bulkhead and one end of the drum, which is penetrated by two concentric axial air ducts, one of which communicates, through an aperture in the partition, with air on one side of the grain floor, and the other communicates, through holes in the bulkhead, with air on the other side of the grain floor. Stationary ducts engage the two concentric ducts, which are sealed from each other and from the air outside.

A ventilator outlet providing alternatively a jet of air or a diffused stream comprises an outer cylinder 1 with one or more ports 2 in its lateral wall and ports 4 in an end plate 3, an inner cylinder 6 rotatable within it with similar ports 8, 9, and a duct 10 connected to the end plate of the inner cylinder and forming a partition with the side and end ports of the cylinders, a directional outlet nozzle 14 being located in the flared end of the duct which projects beyond the open end of the inner cylinder. As shown in Fig. 3 when ports 2, 8, register the end plate ports are masked and air entering the annulus between the duct and inner cylinder issues as a diffused stream. When ports 4, 9, register a central jet is provided and in a further position of the inner cylinder all the ports are masked or a separate shutoff arrangement may be incorporated in the outlet 14. Intermediate positions provide a combined jet and diffused stream. An indicator pointer 15 is attached to the inner cylinder flange.

摘要： 872,931. Clamp fastenings. STEWART, I. M. Dec. 11, 1959 [Sept. 13, 1958], No. 29400/58. Class 44. [Also in Group XXVIII] A fastening device for interconnecting adjacent end portions of two ducts 3, 6, for example, comprises at least two rods 1 adapted to be secured to the inner wall of the end portion of the duct 3 to project axially therefrom, and a catch 4 of spring metal associated with each rod and adapted to be secured to the inner wall of the end portion of the duct 6, each catch being approximately U-shaped, and the limbs 7 of each catch being formed with registering apertures for passage therethrough of the associated rod and with hooks 8, for example, for interengaging the limbs. When the ducts 3, 6, are to be interconnected the hooks 8 on each catch 4 are interengaged, the rods 1 are passed through the registering apertures in the catches and then the hooks 8 are disengaged, a handhole 9 in the wall of the duct 6 being provided for this latter purpose. Disengagement of the hooks 8 allows the limbs 7 of the catches to spring apart to the position shown, to lock the associated rods. A seal 10 may be interposed between the end portions of the ducts.

摘要： 756,089. Cabin and deck lights. STEWART, I. M. March 17, 1955 [March 29, 1954], No. 9046/54. Class 113. [Also in Group X] A lighting installation for a ship includes a ceiling proper 1, Fig. 1, such as an overhead deck, a false ceiling 2 formed by a series of horizontal sheets 3 of translucent material suspended from the structure 1, and illuminating means such as strip lamps 21 located between the ceilings 1 and 2. As shown, each sheet 3 is supported by telescopic tracks 4, Fig. 2, each of which consists of a bar 5 having a central portion 5b of inverted T-section and end portions 6a of I-section, a second bar 6 of I-section aligned with bar 5 and a pair of equispaced bars 7, 8 of inverted L-section which are engaged by connecting piece 9 so as to slide along the bar 5, 6. A sleeve 10 slidably mounted on the lower flanges of bar 5, 6 masks the track 4 from below and has a pin 11 to locate an adjoining sleeve. The tracks 4 are fitted by brackets 12 to supports 13 secured to opposed walls 13a, the tracks 4 adjacent to a wall being secured thereto by a bracket 19 1 . Each track 4 is suspended from the structure 1 by one or more straps consisting of two L-shaped portions 14, 15, which are interconnected at their ribbed ends 16 through slots 17. The tracks 4 are spaced apart by tubular rods 18 having slotted ends which engage the lower portions 16 of straps 14. A draft shield 20, pivoted at one end to each bar 5, may be swung downwardly when the sheet 3 has been unrolled and is in position on the tracks 4, to prevent displacement of the sheet.

摘要： 749,548. Ventilator grilles. STEWART, I. M. Nov. 3, 1954 [Nov. 13, 1953]. No. 31491/53. Class 137. A grille for mounting, e.g. on an air duct comprises a main grille plate 1 which is fitted to a second grille plate 1a to present a plurality of elongated discharge nozzles 2, both plates being formed with spaced angle section ribs 4, 3 which, when the grille is assembled, overlap, and may be adjusted relative to one another to regulate the size of the nozzles. Each of the plates 1, 1a may be shaped individually from a blank, or they may be moulded from plastic material.
