Patent GB-764480-A (GB)
Abstract: 764,480. Photographic shutters. PETO SCOTT ELECTRICAL INSTRUMENTS, Ltd. Oct: 11, 1954 [Oct. 27, 1953], No. 29721/53. Class 98(1) In a pivoted-blade shutter, the blade operating mechanism has, in addition to the usual operating means, a spring which assists the initial parts of both the opening and closing movements of the blades and resists the latter parts of both these movements, additional shutter - operating means being connected to the blade-operating member to determine the time of initiation of the opening and closing movements. As shown, the five pivoted blades 13, Fig. 2, are connected by links 16, and the lug 17 on one blade is connected by the link 34 to a rocker arm 33 connected to an inner torsion member 70, Fig. 6, carried in a roller bearing 71 and joined at its outer end to an outer fixed torsion tube 69. The rocker 33 is joined by a rod 32 to a crank 31 carried on a spindle 30, Fig. 5, mounted in bearings and surrounded by a helical spring 35 connected at one end to the spindle and at the other to a sleeve rotatable in bearings and carrying a pinion geared to an electric motor whose circuit includes a switch closed as soon as the spring is unwound to effect rewinding. A collar 155 fast on the spindle 30 carries a radial stop 156 engageable by one of the two abutments 59, 60 on the cam 57 pivoted on pins 58 and carrying an operating arm 62 carrying an electromagnetically actuated armature. Tilting of the cam 57 on actuation of the electromagnetic release frees the stop 156 from the abutment 59 and permits the spindle 30 to make half a revolution (to open the shutter) until the stop 156 engages the abutment 60; when the cam 57 tilts in the other direction the stop 156 is again freed and the shutter permitted to close. The torsion elements 69 and 70 are arranged to exert no force on the mechanism in the mid-position of the rocker 33, and these act to accelerate the blades in the first halves of both the opening and closing movements and to decelerate the blades in the second halves of these movements. The spring 35 need only be strong enough to move the crank 31 past its dead centre. The speed of the shutter may be adjusted by a lever controlled by a rotatable screw and connected to escapement mechanism. The operating spring may be replaced by an electromagnetic, hydraulic, pneumatic or fly-wheel operated drive, and the torsion device may be replaced by a leaf-spring. Specification 483,196 is referred to.

Title: Line of sight stabilisation
IPC: G12B5/00
Filed: 1979-11-14
Abstract: A control device 4 for optical apparatus, particularly an image stabiliser for a hand-held camera 2, comprises a control mechanism, such as a gyroscope rotor 12 or inertial mass, mechanically coupled to a mirror 9 which receives light from a scene viewed and reflects this light onto a second reflecting surface, which may be a face 10 of a prism, from which the light is further reflected to the apparatus. A transparent material having a refractive index greater than that of air is also present in the optical path and may be the prism. Yhe gyroscope rotor 12 or mass tends to maintain its position during vibration and tremor of the device and this relative movement is transmitted to the mirror to maintain steady the image seen by the apparatus. The material of the prism produces refractive effects which enable the mirror to be small enough to allow mechanical coupling thereof to the control mechanism, i.e. without servo-motors, while still accommodating the wide field of view normally accepted by a camera. The invention may also be applied to a device which steers the line of sight of the apparatus. <IMAGE>
