Abstract: 445,965. Vacuum cleaning-apparatus; dust filters. BOOTH, S., and BRITISH VACUUM CLEANER & ENGINEERING CO., Ltd., Parsons Green Lane, Fulham, London. Dec. 28, 1934, No. 37203. [Classes 8 (i) and 8 (ii)] A vacuum dust-removal device especially for removal of ash &c. from ships' boilers comprises a number of filter chambers 1 each mounted on a housing 3 capable of air-tight closure and containing a removable dust collecting receptacle or bag 32 ; dust-laden air is drawn alternately through the remainder of the filter chambers while one is being cleaned. The filter fabric is folded into concentric conical portions 16, 17 suspended by hooks from a resiliently mounted ring 19. The dusty air enters by an axial metal cone 25, discharging the larger solids into the bag &c. 32 secured to the conical portion 30 of the filter chamber, while the partly cleaned air flows up through the filter bag. Valves control the connection of the chambers 1 with the suction hose and with the air suction pump. The vacuum in a chamber may be relieved by opening a valve 45 before opening the door of the corresponding housing 3 ; the doors are closed air-tightly by cams actuated by handles 40. The filling of the dust bag 32 may be indicated by electrical contact means operated by the weight of dust to give an audible or other signal. The suction nozzle may comprise a cone having air-holes in its surface ; Fig. 9 shows a nozzle for removing heaped material having a dust inlet 47, and a shield 49 for the annular air inlet 50.

IPC: H01K3/02
Filed: 1930-12-19
Abstract: In the manufacture of tungsten wire consisting of long crystals, drawn tungsten wire is passed continuously through a single heating zone of a temperature exceeding 2000 DEG  C. in order to effect crystal transformation at a speed that is several times the speed of crystal growth, i.e. at a speed greater than 10 metres per hour.  For ordinary filament wires, the speed is usually 100-300 metres per hour.  In an example a tungsten wire of 0,17 mm. diameter is drawn at a speed of 2 metres per minute over two tungsten contacts which serve to supply the heating current and which are arranged at a distance of 30 cm. apart in an atmosphere consisting of three parts of nitrogen and one of hydrogen.  The part of the filament between the contacts is heated to 2400-2600 DEG  C.  Specifications 16620/14, 155,851, 174,714, and 181,703, [all in Class 39 (ii), Electric Lamps, Incandescent], are referred to.

Title: Roll film camera
IPC: G03B1/66
Filed: 1960-11-10
Abstract: 888,557. Photographic cameras. AGFA A.G. Nov. 10, 1960 [Nov. 19, 1959], No. 38713/60. Class 93(1). In a roll film camera having for control of a film advancing and an exposed image counting mechanism, a measuring wheel responsive to the film movement between consecutive film frames, means are provided for immobilising said measuring wheel in a particular position during insertion of a film into the camera, said means including a heart-shaped cam fixed to the measuring wheel or to its spindle, and a lever arranged to exert pressure on said cam. As shown (Fig. 2) a measuring wheel 3 having teeth projecting into the film path 1a is provided with a heart-shaped cam 4 attached thereto, the arrangement being such that when the camera back 5 is opened, a spring urged lever 6 is released by a pin 8 and an end portion of this lever 6 engages said cam and rotates it into a position in which said end engages in a slot 37 of the cam 4. After a film has been loaded into the camera and wound on until an indication mark on the paper leader registers with a mark provided adjacent to the film path, the camera back 5 is closed whereby cam 4 is freed from lever 6. At the same time by means of a pin 24 on the lever 6 and by way of a coupling lever 23 (Fig. 4) a spring-urged feed-lock lever 13 is released from an inoperative position in which an arm 15 thereof was held out of engagement with ratchet wheel 16 on feed spindle 31. However, owing to the reduced depth of the first few teeth of exposure frame counting wheel 12, which teeth are explored by an arm 17 of the lever 13, the feed-lock does not become operative until the whole of the paper leader has been wound on and the first image frame lies in the exposure aperture. Likewise, teeth of reduced depth are provided so that the paper trailer can be wound on without interference from the feed-lock. The counting disc 12 is rotated tooth by tooth-one for each image frame wound onby means of a pin 10 on a cam disc 9 fixedly mounted on the spindle 30 of the wheel 3. After each film advance end 14 of lever 13 engages in slot 11 of disc 9 and the ratchet wheel 16 becomes locked by the arm 15. The feed-lock is released by actuation of the camera release member which comprises a knob 21, a longitudinally slidable shaft 27 for actuating the shutter release, and a sleeve 22 slidable with respect to both the housing 1 and the shaft 27. Before each exposure, arm 19a of a spring-urged lever 19 engages the side of sleeve 22. On depression of knob 21, arm 19a slides on to knob 21, and after release of knob 21 on to the shaft 27, the sleeve 22 then. being held in the position shown in Fig. 5. In this position, abutment 19b of lever 19 engages an abutment of the feed-lock lever 13 and moves the same into an inoperative position. The engagement between levers 19 and 13 is released during the next advance of the film as a result of the engagement of an arm 19c of lever 19 by pin 10.

Abstract: 993,844. Drafting-apparatus. JAMES MACKIE & SONS Ltd. Nov. 20, 1961 [Nov. 22, 1960], No. 40130/61. Heading D1D. In drafting apparatus, with an apron between the drawing and retaining rollers, at least a part of the length of the apron in the region of its end adjacent the drawing rollers is supported over a continuous length at either side of the line of the material being drafted and not along the line of the material itself. The whole or one quarter or one sixth of the length of the apron may be supported in this way. The apron concerned may be an upper or lower apron and a support plate therefor may be provided with a groove or slot; or the apron may have two support plates one on each side of the sliver path. When a second apron cooperates with the apron, that too, may be similarly supported by a grooved or dotted plate or two separate plates; further, the roller around which the apron passes adjacent the drawing rollers, and if desired, the roller at the opposite end of the apron, may also be recessed in line with the sliver. In Fig. 1, a lower apron 20 of a two-sliver unit passing around rollers 22, 23 is tensioned by a freely-hanging roller 28 and driven by a roller 21. The apron is supported by a plate 40 secured to side plates 24 in which the rollers 22, 23 are journalled, the plates being attached to the machine frame 27 by pins 25 in slots 26. In the path of each sliver, the plate has a groove, the rollers 23, 24 being also grooved, the grooves being wider than the corresponding conductors 2, 5 and 7. Several ways are described whereby the sliver is pressed against the lower apron. (a) In Fig. 1, a second apron 31 is provided; it passes freely over rollers 32, 33 and over a support plate 34, the rollers and plates being mounted in side-plates 35 located by pins 36 in the frame 27 and constituting a recovable unit. Pressure is applied to this assembly by conventional means. (b) In Fig. 4, a series of rollers 50.. 53 is journalled in plates 55 carrying the grooved plate 30, and the rollers 22, 23, and having lugs 60, 61 resting on a bar 62 and extensions 63 engaging the ends of the tensioning roller, the whole assembly constituting a removable unit. (c) In Fig. 6, the plates 55 have upward extensions 72 carrying a pin 71 on which is hinged a plate 71 adjustably loaded at 73. (d) In Fig. 7, not shown, a similarly hinged plate loaded by interchangeable weights, has hinged thereto a second loaded plate shorter than the first, whereby the parts of the apron may be differently loaded.
