Filed: 1968-10-03
Abstract: 1,223,586. Winding and shutter mechanism. MINOLTA CAMERA CO. Ltd. Oct.3, 1968 [Oct.4, 1967], No.47052/68. Heading G2A. A film-winding shaft is linked with means for tensioning the shutter. As shown, the shaft is operated by a knob 2, and a gear 3 fixed to it is connected by a gear train 4, 5, 6 to a gear 7 which is without teeth over a peripheral part 8 extending slightly less than 180 degrees. The shaft and the gears are supported by a table 1. The pin 9 on which gear 7 rotates extends through table 1, and to its lower end is fixed a cranked arm 11, 12 connected by a tension spring 14 to a fixed pin 15. The part 12 of this arm forms the actual shutter driving means. The shutter release is a slide 16, guided for movement by an arrangement of pins and slots, and is normally retained in its uppermost position by a spring 17. Slide 16 has a lateral arm 18, with a lug 19 which extends into the path of driving part 12. Fig.1 shows the mechanism in the run-down position, just after an exposure has been made, and in which the first tooth of gear 7 just engages with gear 6. When knob 2 is rotated in the direction of the arrow to wind on the film, gear 7 will be rotated anticlockwise, together with arm 11, 12 thus tensioning spring 14. As the spring passes the dead point, where it has its maximum extension, the part of gear 7 without any teeth is reached. Gears 6 and 7 thus disengage, and arm 11, 12 is then pulled round quickly (still anti-clockwise) until it is stopped by lug 19. The shutter driving mechanism is now tensioned. The shutter itself is a singlebladed member 20 pivoted to the table 1 at 21, and biased anti-clockwise by a spring 22. It also has a lug 23 extending into the path of arm 12. When shutter release 16 is pressed, lug 19 disengages from arm 12, thus allowing it to proceed further and strike lug 23. This pivots the shutter 20 clockwise to uncover the exposure aperture 26 Fig.5, (not shown). In a modification Figs.6 and 7, (not shown) the final gear 6 is mounted on a rocking plate, so that it may be manually brought into engagement with gear 7 if the first tooth of the latter has not quite reached it.

Abstract: 1,003,331. Clutch control. BORG-WARNER CORPORATION. Dec. 18, 1962 [Jan. 2, 1962], No. 47734/62. e d ngs F2C and F2L. A friction clutch is disengaged by springs and engaged by a servomotor having stop means on its piston rod which are adjusted as wear occurs in the clutch so that the stroke of the servomotor piston remains constant. As shown in Figs. 1 and 4 the clutch is engaged by a servomotor having a piston E-1 fast with a piston rod F engaging a lever D which is pivoted upon a strut 16 and engages a collar 15 to engage the clutch B. Adjustable stop means 41 is provided on the piston rod F and co-operates with fixed stops 40-1, 40-2 to limit the piston stroke, the stop means 41 comprising two Belleville diaphragms 66, 67 formed with inwardly extending fingers 69 gripping the piston rod. Engagement of the outer periphery of the diaphragms with the stop 40-2 tends to flatten the dia. phragms so that they grip the piston rod more firmly, engagement of the diaphragms with the stop 40-1 tends to increase the deflection of the diaphragms to adjust their position on the piston rod to permit full engagement of the clutch. In the modification shown in Fig. 5 fixed stops 140-1, 140-2 are provided inside the servomotor chamber and are engaged by a single Belleville diaphragm which adjusts its position on the piston rod as in the previous embodiment. A seal 160 prevents the escape of liquid along the piston rod, a similar seal being provided in the first embodiment, and the piston is returned to its disengaged position by a spring 118. Specification 1,003,195 is referred to.

Abstract: 1451374 Shaft preheaters; shaft kilns; cooling granular material KLOCKNERHUMBOLDT-DEUTZ AG 15 Oct 1973 [17 Oct 1972] 47965/73 Headings F4B and F4U Apparatus for thermal treatment of granular material, e.g. a shaft kiln, preheater, or cooler has two charging shafts opening into a common chamber 1 which has at least one inlet for heating gases, and the charging shafts are connected to separate gas off-tubes. A preheater for material to be treated in a rotary kiln 20 has an outer feed shaft 2 supplied from hoppers 16, 17 and an inner feed shaft 3 supplied from a hopper 12. The hopper 12 has a depending tube 11 which projects an adjustable extent into the shaft 3. Bars 7 of inverted V-section extend from the inner shaft 3 to the wall of the chamber 1, to protect gas inlet apertures 9 and partially support the material to be treated. Members 18 obstruct the flow of material down the outer shaft 2 and feeds gases to an off-take 4, while an off-take 5 from the inner shaft 3 projects through the outer shaft. Waste gases from the kiln enter the chamber 1 from the side, flow downwardly through material on the bars 7 to the inner shaft through inlets 9, 10 below the material level, and through the open bottom of the inner shaft. Gases enter the outer shaft through the material on the bars 7 at its bottom. The bars 7 are parallel to the natural slope of the material, and the depth of material over the bars 7 is less than the distance from the mouth of the outer shaft 2 to the gas off-take 4 from the outer shaft. Dampers 5<SP>1</SP>, 4<SP>1</SP> in the gas offtakes and the variable height of the feed tube 11 enable the gas flows to be regulated so that the fine material fed down the outer shaft and lumpy material fed down the inner shaft are adequately preheated. In a modification for use as a kiln, burners are arranged around the sides of the chamber 1, discharging on to material supported on the bars, and cold air is delivered above the discharge outlet (Fig. 2). In this case the lump material may be fed down the outer channel and the fine material fed down the inner channel. The apparatus may be used for cooling granular material.
