Title: Brake discs
IPC: F16D65/12
Filed: 1974-05-30
Abstract: 1469115 Brake discs; reducing noise GENERAL MOTORS FRANCE 22 May 1975 [30 May 1974] 24056/74 Heading F2E A brake disc 1 for a disc brake has in its outer periphery a circumferential groove 2 having a base surface 4 and two wall surfaces 3, into which groove 2 is fitted an annular member 5 with at least one surface thereof in frictional contact with and bonded by a resilient cement to, one of the surfaces of the groove 2 so as to allow some degree of resilient movement between said one surfaces of the annular member 5 and the disc 1, whereby, when the disc 1 is exposed to vibration in use, the frictional forces generated between the surfaces alternate the vibration and decrease its audibility. By resilient cement is meant an adhesive, for example a heatresistant epoxy resin cement which, after setting, permits some slight degree of freedom of movement between the secured surfaces without breaking the adhesive bond. In the embodiment of Fig. 2, the wall surfaces 3 are parallel and the annular member 5 comprises two ring-shaped laminµ 6 stacked in the groove 2 with their flat radial surfaces forming frictionally-contacting surfaces; these surfaces are bonded by resilient cement and the radial surfaces contiguous with surfaces 3 are bonded thereto. In the embodiment of Fig. 3 (not shown) the groove (2) has radially inwardly converging side surfaces (3) and the complementary shaped annular member (5) has its side surfaces (7) bonded thereto. In the embodiment of Fig. 4 (not shown) the annular member (5) comprises two rectangular cross-section rings (6) of different diameters placed one upon the other and bonded to one another and with the radially inner ring bonded to the base surface (4). A clearance (8) is left between the sides of the rings (6) and surfaces (3). The embodiment of Figs. 5, 6 shows an annular member of waved contour with the surfaces 9 being bonded to the side surfaces 3. In the embodiment of Fig. 7 (not shown) an annular member of waved contour form has its crests (10) lying on the inside circumference of the annular member and bonded to the base surface (4), and a clearance is provided between the member (5) and the side surfaces (3). The annular members could be in the form of closed loops, open loops or comprised of separate segments evenly distributed around the groove, the annular members may be of metal or synthetic resin material. More than two laminµ bonded together could be used in an annular member-the resilient cement could be applied over the whole area of the contiguous surfaces of the laminµ, or could be applied at certain areas only. Each lamina could be formed from separate segments cemented to one another.

Title: Process and apparatus for extracting dust and fume from gases or air in which they are carried in suspension
IPC: B01D45/08
Filed: 1922-09-06
Abstract: 185,746. Milliken, H. Sept. 6, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Dust-collectors.-Dust, &c. are separated from gas or air by causing the dust-laden current to impinge more or less squarely against surfaces at their edges, the current then travelling parallel to the surfaces at a reduced velocity and depositing the dust &c. on the surfaces before being. redirected with an increased velocity prior to further impacts. Figs. 1 and 3 show a separator in which the gas entering at the end 22 is deflected by curved vanes 16 against the edges of collecting-plates 17 on which the dust &c. is deposited, sliding down their inclined surfaces through a perforated wall into a collecting-chamber partitioned by plates 14 and having a door 24. Baffles 25 prevent air disturbance within the chamber. Hammers 18 on a shaft 19 strike the casing to prevent caking. The air after passing through the first set of plates 17 is deflected oppositely with increased velocity against the next set. In a modification, the successive sets of vanes are aligned obliquely within the casing, and are all curved in the same direction. Several apparatus may be employed in series, the separated dust passing down out of contact with the air either by an external passage, or, through internal passages 21, Fig. 4, formed by oppositely curved vanes.
Patent GB-1501418-A (GB)
Title: Film advancing mechanism
IPC: G03B17/42
Filed: 1975-06-04
Abstract: 1501418 Film advancing mechanism FUJI PHOTO FILM CO Ltd 4 June 1975 [6 June 1974] 24188/75 Heading G2A A film engagement element 4 having a film entrainment member 2 has coupled thereto an actuating element 6 which, when driven by a rotary drive means, transmits the drive to the element 4 which advances the film. Element 4 is a slide, biased to the left by a spring 3. Element 6 is a generally similar slide, connected to slide 4 by a spring 20. Slide 4 has a projection 21 which can engage with a projection 22 on slide 6. On the lower edge of slide 4 is a toothed rack 23, which co-operates with a spring-loaded pawl 24. The pawl is clear of the slide either at one end, Fig. 2(d), or at the other, Fig. 2(a), these being when the slide is positioned at 4I or 4II. Thus the slide 4 can be moved from position 4I to position 4II, or vice versa, but its movement cannot be reversed at any intermediate position between the two because pawl 24 locks the rack 23. Fig. 2(a) represents the position when the mechanism is cocked, slide 4 being held in its extreme right position by a pawl 16 locking with a latch portion 17 on the slide. When the shutter release is pressed to effect an exposure, pawl 16 is pivoted anti-clockwise, so that it no longer engages with latch portion 17. At the same time a motor is started which rotates a plate carrying a pin 15. Since latch 17 is freed, slide 4 moves to the left, under the action of spring 3, slide 6 also being drawn in the same direction because of spring 20. During this movement, if pin 15 engages with an angle plate 13 on slide 6, so temporarily reversing its movement, plate 4 does not follow this movement because rack 23 is locked by pawl 24. Eventually both slides reach the I position, Fig. 2(d). In this position the entrainment member 2 hooks behind the exposed film sheet. As pin 15 engages angle plate 13 again, slide 6 is moved to the right again, taking slide 4 with it, since spring 20 is stronger than spring 3. Thus the exposed film sheet is drawn to the right, and, if the camera is of the auto-process type, delivered to the pressure rollers. Instead of separate film sheets, the mechanism of the invention can also be applied to the transport of roll film having one perforation per film frame. Fig. 3 (not shown) is a modification having only one slide.
