IPC: F16C21/00
Filed: 1966-11-23
Abstract: 1,104,478. Bearings; lubricating. ROLLS-ROYCE Ltd. 23 Nov., 1966, No. 52522/66. Heading F2A. [Also in Division F1] A hydrodynamic film of lubricant is maintained between an outer race of a rolling bearing and its support, the lubricant being withdrawn from the bearing so as to obviate the necessity of a separate source of lubricant supply for the film. In an embodiment, in order to damp vibrations transmitted to a support-member 18 from a rotating shaft 12, Fig. 2, a hydrodynamic " squeeze " film of lubricant is maintained in an annular clearance 30 provided between a cylindrical outer surface of a bearing outer race 17 and a cylindrical inner surface of the support-member 18. Lubricant for maintaining the " squeeze " film is taken from a layer 27 of lubricant which has been centrifuged from the bearing. The layer 27 supplies lubricant to the clearance 30, via galleries 32; passages 31 in the outer race 17; stand-pipes 35, which are mounted in a reservoir 34 and have baffles 36 therein; passages 37, which lead from the stand-pipes 35 to a reservoir 34 in the support-member 18; outlet passages 38, which are disposed centrally of the reservoir 34 and communicate with a central channel 40; and the latter which connects to the clearance 30. The purpose of the baffles 36 in the stand-pipes 35 is to de-aerate the lubricant. In another embodiment, a reservoir 44, Figs. 3 and 4, is formed between a flat portion 42 on a support-member 18 and a cap 43 attached thereto. A layer 27 of lubricant is connected to the reservoir 44, via passages 31 in an outer race 17 and passages 31a in the support-member 18. The reservoir 44 is connected to a " squeeze "-film clearance 30, via an aperture 45 in the support-member 18. Baffles 46 are positioned in the reservoir 44 to assist in separating air from the lubricant, the air escaping through vent-holes 47 in the cap 43.

Abstract: 1286099 Multi-flash rotating devices FUJI PHOTO FILM CO Ltd 26 Nov 1969 [27 Nov 1968] 57920/69 Heading G2A A photographic camera includes a rotary socket 1 for a multi-flash unit, e.g. a flash-cube; means for rotating the socket for advancing bulbs of an inserted unit to an ignition position; a ratchet 2 and pawl for arresting the socket against such rotation, the pawl lever 3 being biased out of engagement with the ratchet; and two independent holding means for holding lever 3 in engagement with ratchet 2, one holding means being a lever 4 coupled to the exposure regulating device of the camera and only freeing the lever 3 when the prevailing illumination is such as to require a flash-light exposure, and the other holding means being a stop 5 coupled to a shutter actuating means so that it frees the lever 3 upon operation of the shutter. In use, in the normal range of exposure value settings of the automatic exposure regulating device, a pointer (101) Fig. 3 (not shown) of an exposure meter galvanometer (100) lies in the path of rotation of a lever (51) which is spring urged to follow the movement of shutter release slide (9). Hence when this slide (9) is depressed, the lever (51) can rotate a little way before being stopped by the pointer (101), this serving to control the exposure setting of the camera. Since the lever (51) is stopped, the stop 5 remains in the path of the pawl lever 3, so the socket 1 cannot be rotated. When the pointer (101) moves to a position denoting insufficient available light, it is out of the path of movement of the lever (51), which consequently follows the slide (9) all the way, and thus depresses the stop 5 out of the path of the pawl lever 3. The depression of the slide (9) rotates a lever 8 to actuate the shutter, ignite the flash-light, and rotate a lever 7 connected to the holding lever 4, so that the pawl lever 3 can rotate to free the ratchet 2 for rotating the socket 1. During the socket rotation, the levers 7, 8 and 4 are returned to their original positions, so the ratchet 2 only rotates by one tooth. The stop 5 is returned to the position shown as the slide (9) rises.
