Title: Improvements in or relating to thrust bearings
IPC: F16C19/10
Filed: 1919-10-06
Abstract: 156,327. Boberton, C. G. Oct. 6, 1919. Thrust bearings.-In a thrust bearing of the pivoted-block type, each block or pad D bears flat against a thrust ring B on the shaft A, and has a spherical rear surface, d<1> which is supported at either three or four points distributed around the centre of the block, the support at two points at least being upon balls, to allow angular freedom of the pads. In Figs. 1 and 4, each block is shown supported at three points, two being on balls E and the other on the sloping surface c<1> of a channel c in a fixed member C. A stop F, adjustably screwed into the member C, prevents side displacement of the balls and pads, and mav replace one of the balls. As shown in Fig. 4, the slight play of the balls permits the pads D to open slightly at the entrance edge of their bearing-surfaces d to facilitate the entry of oil. In order to take thrust in both directions, the collar B may have pads and balls arranged on each side; or a pair of thrust collars may be used, encircling a fixed member provided with pads and balls on each side. In a modification, the spherical surfaces of the pads D, Fig. 7, are supported at four points by means of two rings of balls E, E<1>. Clips G may be used to retain the collar B in place in the bearing.

Title: A photographic flash-lamp device
IPC: G03B15/04
Filed: 1958-01-01
Abstract: 872,639. Photographic flash lamps. GENERAL ELECTRIC CO. Jan. 1, 1958 [Feb. 13, 1957], No. 24739/60. Divided out of 872,638. Class 9(2). [Also in Group XX] A lamp containing actinic material is flashed by connecting the electrodes to a piezoelectric crystal 46 and deforming the crystal to produce the necessary electric energy. Leads 47, 48 connect the crystal to a photoflash bulb such as described in Specification 29/58, and deformation of the crystal is synchronized with a camera shutter mechanism. When a plunger 16 is depressed, a lever 19 is rotated and stresses a spring 21, which engages a lug 23 on a shutter member 24. Lever 19 moves away from a projection 26 of the member 24 and strikes a bell-crank lever 28 causing the latch 31 to disengage from a lug 32 of the member 24. The spring 21 then rotates the shutter and exposes the aperture 33. As the shutter pivots, a pin 36 moving in a slot 37 moves a lever 34, so stressing a spring 38 that, at the instant the aperture 33 is uncovered, a disc 40 rotates, bringing an arcuate slot 42 across the aperture 33. A stop 44 limits the movement of the disc 40. While the shutter operates, the lever 34 releases an arm 51, which is rotated by a spring 53, so that a hammer 55 strikes the crystal 46 and thus generates a high voltage to flash the lamp. On release of the plunger 16, a spring 54 returns the arm 51 to its original position, the plunger and shutter members 24, 40 being returned by a spring 17.

Abstract: 799,812. Ophthalmic photography. ZEISSSTIFTUNG, C., [trading as ZEISS. C.], [Firm of]. Sept. 1, 1955 [Sept. 2, 1954], No. 25090/55. Class 97(1) In an illuminating arrangement for photographing the fundus of the eye in which intermediate images of source 1 are formed adjacent an inclined mirror 5 and at 3, in the plane of co-axial diaphragms 9 and 10, the sizes of apertured diaphragm 9 and central obscuring diaphragm 10 are adjustable, the adjustment of the latter being such that the image conjugate with its corneal image and formed adjacent an aperture 6, preferably provided in mirror 5, can be made larger than the aperture 6. The annular illuminated area 1<SP>1</SP> projected on the cornea 8 is internally bounded by a sharply demarcated image of the periphery of diaphragm 10 and the size of diaphragm 10 is preferably adjusted so that area 1<SP>1</SP> is separated from a central area of the cornea 8, the emergent rays from which all pass through aperture 6, by an annular zone free from incident light. Colour fringes at the inner periphery of the ring- shaped image 3 of a ring-shaped source 1 are obscured by diaphragm 10. The colour fringes at the outer periphery are obscured by diaphragm 9 and the maximum illumination of the eye, especially for colour photography is obtained by arranging that the image of the source 1 on the cornea 8, when the diaphragm 9 is removed, is larger than the pupil of the eye and, when the diaphragm is replaced, is slightly smaller than the pupil. Lenses 4 and 7 are chromatically corrected and photographic light sensitive material is placed at 12. Specification 782,546 is referred to.

Abstract: 1,045,078. Automatic character reading. FARRINGTON ELECTRONICS Inc. June 25, 1963 [July 6, 1962], No. 25248/63. Heading G4R. In an automatic character reader in which characters in a line are read successively by directing an image of each in turn to a scanning device by means of a pivoted mirror, each character area is also illuminated in turn by a small spot of high intensity light projected on to the character area being scanned by a second mirror moving with the first. The characters are projected by tilting mirror 11, Fig. 2, lens 23 and prisms 24-27 and 29, 30 on to two positions on a slotted dissecting disc 28. The mirror 11 is mounted on a shaft 12 rocked by a cam mechanism so that the area present at the scanning position sweeps along the row of characters from one end to the other. The same area is illuminated through mirror 14, also on shaft 12 by lamp 15. The image at one position on plate 28 is inverted and reversed compared with that at the other position. Slitted mask plates 33, 34 are provided at each scanning position, each having two vertical slits. The light from each slit passes to a photocell, the signals from each representing successive vertical scans through the character, Fig. 4. Signals from slits 33b and 34b may be used to provide character information, the prisms being adjusted so that the corresponding scans relate to the same portion of the character or to adjacent portions. Character line slope and joinings &c. are readily detected in the latter case. Alternatively, the scans of one slit may be arranged between the scans of the other so that a double-density scan is obtained for a given speed. Signals from slit 33a may be used to adjust the recognition circuitry to compensate for non-registration of the character. Slit 33a in effect performs a pre-scan. The last slit 34a may be used as a " Character present " detector, the corresponding photo-cell producing either a white " character absent " signal or a black signal which allows recognition to take place.
