Title: Method and apparatus for forming a fibrous mass
IPC: D04H1/00
Filed: 1961-11-24
Abstract: In forming glass fibres prior to the production of a high density fibrous glass mass a molten glass stream 11 is fed into a centrifuge apparatus 10. At the lower end of the centrifuge the molten glass is distributed by an air jet 16 on to the inside of a peripheral wall 17 of the centrifuge. <PICT:0952234/C1/1> <PICT:0952234/C1/2> Wall 17 has a large number of orifices therein, preferably some being larger than others, such that streams 24 of molten glass are projected outwardly by centrifugal force. The glass filaments are then subjected to a downwardly directed attenuating blast from an annular orifice 28 of a steam blower 29, which directs the fibres on to a collecting conveyer. Below the orifice 28 the blower 29 has an outwardly inclined wall 47 and continuing downwardly, an outwardly flared annular skirt 48.  The skirt 48 has a curved contour which with the effect of the blast jet 27 produces a region of low pressure between the jet and the skirt.  This produces turbulence which interrupts the attenuation of some of the fibres and fractures some of the longer fibres. The skirt 48 has a cooling space 49.

Abstract: 1,162,011. Feeding and delivering sheets; endless conveyers. NETHERLANDS, POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 29 Sept., 1966 [5 Oct., 1965], No. 43599/66. Headings B8A and B8R. Apparatus for guiding letters, forms or the like into a receptacle 1 and removing them separately comprises, toothed or grooved conveyer bands 2, 3, 4 on both the bottom and one closed side of the receptacle and which are driven and stopped simultaneously as determined by the pressure exerted by the front or removing end of the stack. When the pressure in the receptacle is light, a feeler 5 pivots clockwise, Fig. 1, and a switch is closed to cause the belts 2, 3, 4 to be driven. A second feeler at the rear of the stack allows the stack feeding device 21 to move backwardly if pressure demands. This is done by a motor and a toothed wheel 23 which fit in the teeth of a conveyer band 4. The letters are removed from the receptacle one-by-one by a centrally grooved removing belt 7 driven continuously by pulleys 8, 9. Pulley 8 is on a fixed axis, but pulley 9 may swing about the axis of pulley 8 by the operation of a magnet 10 which is operated when the leading edge of the letter is sensed by photoelectric device 11, 12. The letter is, at this moment, between the pulley 8 and a feed roller, so it continues to be fed, but since the pulley 9 has been swung away a further letter cannot feed out. When the first letter is detected by a second sensing device, i.e. photo-electric cell 16, a lock 17 is actuated. This lock comprises a roller 14 between two arms of a fork 17 pivoted at 19 and actuated by an electromagnet 18. Actuation of the lock ensures that the first letter is fed by the rollers 13, 14 but a second letter is locked by the arms (17, Fig. 3, not shown) of the lock. When the first letter passes the second sensing device 15, 16 the lock is reopened. Opposite the removing belt 7 and at the side in which the letters are removed is a separating device 20 comprising three blocks 31, 32, 33. The middle block is smooth with a projecting rib and the outer blocks 31, 33 are of high friction material and spaced a little forward of the block 32 to effect a slight bowing of the letters.

A photographic or kinematograph camera having a built-in photo-electric exposure meter and a zoom lens 2 has a further zoom lens 10 arranged in front of the photosensitive element 6 of the exposure and the focusing mechanism for both lenses are coupled, e.g. by a parallelogram linkage 5,17,14 as shown or by a similar linkage connected to a worm engaging a toothed ring on each lens. The photo-cell zoom lens may have one or more components of synthetic resin and that adjacent the photosensitive element 6 may be matted or otherwise rendered diffusing so that light is concentrated on and spread over the element 6. If the two zoom lenses are not identical the connection between the focusing mechanisms must be such as to provide appropriate different movements as by making the links 5,14 dissimilar or by employing different gear ratios for the movable elements of the lenses.
