Abstract: 752,733. Ventilators. INTERNATIONAL ANEMOSTAT HOLDING CO., Ltd., Aug. 19, 1954 [Aug. 20, 1953], No. 24207 /54. Class 137. A diffuser for mounting across the outlet end of a flared air supply duct 18 comprises a circular element 12 which is formed from a sheet of material, e.g. metal, which is pleated and bent to provide inwardly and outwardly extending channels 14, 16, the air from the duct flowing outwardly into the enclosure to be ventilated along the channels 14 to cause a constant replacement flow of enclosure air to be entrained in the channels 16, the two streams of air mixing in the immediate vicinity of the diffuser. The proportion of fresh air to enclosure air is determined by the relative sizes of the channels 14, 16, the channels 16, for instance as shown in Fig. 12, being made relatively large to give a high proportion of enclosure air. The central opening of the element 12 is closed by a frusto-conical shaped core 20 having an outwardly extending flange 22 which overlaps the inner marginal portion of the element 12, the latter being fastened to the front end of the cone 20 by a bolt 24 and a disc 26 which overlaps the inner front marginal portion of the element 12. A ring 28 fastened, e.g. by welding, to an outer edge of the element 12 assists in maintaining the forward flaring of the element 12, the ends of tongues 32, fastened to the ring to the element 12, being engageable in sockets 34 in the duct 18 for removably mounting the element 12 in the duct 18. Alternatively the ring 28 may be fastened to a plurality of radially extending struts, not shown, disposed in certain of the channels 16 and fastened at their inner ends to the cone member 20, the tongues 32, if desired, being fastened to the outer end portions of the struts. To assist in deflecting the air laterally outward and to promote mixing with the enclosure air, flaring elements 38, 40 may be fastened directly to the element 12 or, to the struts, if used. Flaring elements 42, may if desired, be mounted in front of the element to ensure flow of enclosure air into the channels 16. In a more simple arrangement, Fig. 1, an element 12 having transverse channels 14, 16 open at one, or both ends, is arranged across the outlet of an air duct 10.

Title: Improvements in gyro-horizons with optical horizon indication
IPC: G01C19/44
Filed: 1945-09-19
Abstract: 605,058. Gyro-horizons. DIXON, M. G. (Aktiebolaget Nordiska Armatur-fabrikerna). Sept. 19, 1945, No. 24230. [Class 97 (iii)] In a gyro-horizon, the horizon-line is indicated on a visor 46 by the edge of a shadow produced by a swinging screen 43 on the outer gimbal 37 in the light of one of a pair of straight filament lamps 39, 40 carried by the inner gymbal 38. The screen 43 is pivoted on pins 44 on a transverse axis of the aircraft and carries a stop 48 to engage one or other of the adjustment screws 49, 50, the horizontal edge of the shadow on the visor being produced by the edge 45 of the screen in normal flight and by the edge 47 when flying upside down. When the aircraft turns about its transverse axis through 180 degrees the arrangement shown in Fig. 1 is reversed so that the other lamp 40 becomes nearer the visor and co-operates with the screen to produce the horizon indication. The horizon-line passes through the centre of the visor when the aircraft is in the normal horizontal position. Rise and fall angles of up to 30 degrees may be indicated on the visor after which the visor is wholly light or wholly dark. The lamp filaments 41, 42 are parallel to the axis 36 of the inner gimbal and may be in the same horizontal plane. To obtain unsymmetrical angular indication of rise and fall angles, the lamp filaments and the edges of the screen may be situated above or below this plane. The weight of the screen 43 may be partly balanced by a counterweight 51. The unbalance of weight on the outer ring 37 caused by the incomplete balancing of the screen 43 may be partly compensated by an unbalance of weight on the inner ring 38. The intensity of light from the visor may be varied for day and night flying by two or more rotatable filter discs of polarized material and if necessary by colour filters, of which the visor disc may comprise one.

Title: Improvements in mechanism for applying lids to containers
IPC: B65B7/28
Filed: 1955-08-24
Abstract: 788,083. Lid applying mechanism. COW & GATE, Ltd., and CURSON, H. C. Aug. 23, 1956 [Aug. 24, 1955], No. 24369/55. Class 125(2). Mechanism for applying lids to cans or other containers comprises a stop for supporting a lid in a substantially upright position, a spring- loaded tappet, a guide plate, a pressure plate or wiper adjacent to the stop, and means for conveying and rotating cans relatively to the stop so that as a can engages with a lid on the stop it co-operates with the tappet and guide plate to tilt the lid on to the can which carries it under the pressure plate or wiper to complete the closure. Lids 1 slide down onto the stops 3, from a shoot 2 end to end and vertical. The cans move along the bar 20, being rolled along the pressure plates 29 by a belt 21 moving about pulleys 22, 23. The pressure plates 29 are covered with soft and resilient pads 31, and the pulleys 22 are revolved by means of a motor driving a pulley 37, a belt 36, a large pulley 35, and a shaft 32. The second shaft 32 is revolved by pulleys 33 and a belt 34, the machine being duplicated. As the cans progress along the bar 20, each can engages the inside of the lower rim of a lid and pushes it away from the stops 3, and the spring-loaded tappet 13, springs 19 and the guides 4, 9 prevent the weight of succeeding lids forcing the lid ahead of the can. The lids drop on to the can completely as they pass under the pressure plate 40. The bars 20, and pressure plates 29, 40 are adjustable for different sizes of cans and the stops 3 are also adjustable. The action of applying a lid occurs rapidly so that as the lid descends the can advances at a similar speed, the rotating motion causing the two to engage more accurately.
