Patent GB-1136959-A (GB)
Title: Differential mechanism
IPC: F16H48/22
Filed: 1966-05-24
Abstract: 1,136,959. Differential gear. BORGWARNER CORP. 24 May, 1966 [11 June, 1965], No. 23082/66. Heading F2D. In an automotive vehicle limited-slip bevel differential gear, wherein differential rotation of the usual half-shafts 11 is resisted by cone friction clutches between side wheels 47 and the usual split input casing 17, for lubrication and heat dissipation conical friction surfaces 43 of the input casing are each provided with one or more lubricant channels 63 each of which opens at the surface 43 and has opposite its opening a surface 65 extending parallel to the half shaft axis. Each channel 63 is fed from a reservoir 35 which is formed in the interior wall of the casing, oil being admitted into the casing interior through a radially directed rectangular casing port (33). The axially movable cone clutch members, 55, are integral with, or, as shown, splined on the half shafts 11 for rotation with side wheels 47, the latter being acted on for clutch loading by gear separating force and, for pre-load, a spring pack comprising side-wheel contacting members 59 enclosing compression springs 61. The casing friction surfaces 43 (Fig. 3, not shown) or, as shown the friction surfaces of the clutch members 55 may be helically grooved at 67.

Title: Improvements in or relating to photographic cameras
Inventor: HARTER PAUL
IPC: G03B7/12
Filed: 1962-06-15
Abstract: 1, 014, 492. Photographic cameras. EASTMAN KODAK CO. June 15, 1962 [June 15, 1961], No. 23141/62. Heading G2A. In a photographic camera having a photoelectric exposure meter the pointer of which is explored by a sensing member, upon manual release of the shutter operating member, to adjust the diaphragm aperture and for the shutter speed, a latch is provided which, upon conditioning the shutter for delayed action exposure moves to prevent disengagement of the sensing member until completion of the exposure. As shown, the camera has a photo-electric exposure meter 3 with a pointer 4b the position of which is explored by a sensing member 7 when a slide 5 is depressed by operating the shutter release, such depression of slide 5 allowing downward travel of a sleeve 11 by an amount dependent on the position of the pointer 4b. A stop member 13 on the sleeve sets the diaphragm aperture and/or the shutter speed. Further downward movement of the slide 5 moves a sleeve 14 to actuate a bell-crank 21 and so release shutter trigger 20. By first moving an arm 22b on a ring 22 of the shutter from position X to position V the shutter may be set for delayed action exposure. Such movement of arm 22b causes a projection 22a on the ring 22 to release a pawl 19 from one end of a spring-loaded bellcrank 18 so that the latter will pivot clockwise and bring a latching element 18a into holding engagement with the sleeve 14, thus preventing movement of the sleeve 13 also. When the delayed action mechanism runs down, a pin 23 moves from B to A and pivots the bell-crank 18 so as to release the latch.

Abstract: 1515696 Off-contact printing CANON KK 28 May 1975 [28 May 1974 (2)] 23260/75 Heading G2A A work-piece (e.g. a photo-sensitive wafer) on a carrier is brought into a predetermined spaced relationship with a standard plane (e.g. a mask original) at an operating station (e.g. for offcontact printing) by first bringing the work-piece into contact with a second plane, having a predetermined spacial relationship with the standard plane, at a recording station and recording the position of the carrier relative to the second plane. As shown, a wafer W, which has been attached under vacuum to the chuck 125 of a carrier 4, 5 or 6 at a mounting station I, is raised on the carrier into contact with calibrator pins 12a, b and c at a recording station II whereafter balls 14A, B and C are raised by cam gears 112A, B and C, (the balls and gears forming part of each carrier mechanism) into contact with further calibrator pins 12A, B and C (the driving force being absorbed by a slip mechanism after contact). The wafer is then transferred on its carrier to an exposure station III where the carrier is raised until the balls (which have been maintained in the same positions relative to the upper surface of the carrier) are brought into contact with the lower surface of a mask holder. The balls may be replaced by pins Figs. 6 and 7A-C, (not shown). The three carriers are indexed by a turn-table which is rotatable in 120 degree steps and has openings (for the carriers) corresponding to the stations I, II and III and the carriers are raised from the turn-table to the various stations (which are mounted on a stationary casing 1 above the turn-table) partly by cylinders 7, 8 and 9 and partly by three suction pads 117A, B and C attached to each carrier. Off-contact printing is carried out in the presence of inert gas between the wafer and mask. For contact printing the chuck may be raised relative to the carrier by the application of vacuum.

Abstract: 497,921. Dressing grinding wheels. HORSTMANN, S. A., and HORSTMAN, Ltd. July 6, 1937, No. 23298/38. Divided out of 492,591. [Classes 60 and 124] A grinding-wheel 17, shown as for grinding external screw-threads, and having therein a number of grooves having the shape of the thread, is formed or dressed by a diamond tool 10, which is mounted by a carrier 12 on a holder 13. The holder is rotated, and is traversed axially across the grinding-wheel 17 at a rate equal to the pitch of the thread, so that during the short time the diamond contacts with the wheel, which rotates at a high speed, a groove is cut ; the rotation of the holder 13 may be speeded up between the cutting periods. The holder may be mounted on a quill 14 carrying the lead screw normally used for grinding the thread and which is mounted on a slide 16 adapted to be fed towards the wheel 17, or the holder may be mounted on centres ; the holder, lead screw, &c. may also as shown in dotted lines in Fig. 1, occupy a position other than that occupied when grinding a thread. Grinding-wheels for forming internal threads may be formed or dressed similarly. Specifications 492,591 and 492,592 are referred to.
