Title: Photographic Apparatus
Inventor: PETERSON DEAN MCCORMACK
IPC: G03B9/10
Filed: 1967-05-18
Abstract: 1,186,553. Photographic shutters . EASTMAN KODAK CO. May 18, 1967 [May 18, 1966], No.23180/67. Heading G2A. An impact shutter comprises a blade 14 pivotably mounted on a stud 13 extending from a plate 11, which blade is rotated to uncover a lens aperture 12 by an impulse from an impact lever 26 applied so as to pass through the centre of percussion (C of P) of the blade, C of P being a distance d from the stud along the line through the centre of gravity (C of G) of the blade. The distance d is   given by d = Ig/Mr+ #r where M is the mass of the blade, #r is the distance from the stud of (C of G) and I g  is the moment of inertia of the blade about (C of G). An exposure is made by moving a trigger 36 clockwise as seen so as to slip off the impact lever 26 which then rotates under spring action thus hitting the blade 14 and eventually coming to rest against a stop 49. The blade 14 is pivoted clockwise until a lug 20 thereof engages a rebound member 50 when the blade is returned to its closed position with a spring 15 holding it against a stop 19. The rebound member 50 is connected to a speed adjusting lever 52 the position of which can be varied, thereby varying the shutter speed. For each speed setting except the slowest the blade rebounds off the member 50. For the slowest speed the spring 15 returns the blade to its closed position before the member 50 is engaged. The shutter may be self-setting or may be reset manually or by actuation of film advance mechanism. The blade 14 may be of the type having an arcuate opening therein, which opening is moved into and out of alignment with the lens aperture 12. With impulses from the impact lever 26 and from the member 50 passing through C of P little or no shock is transmitted to a camera causing camera movement during exposure, and thus shutter speeds of up to 1/2000 sec. may be obtained.

Title: Improvements in and relating to the control of compound motors used for rheostatic braking in electric traction systems
IPC: B60L7/24
Filed: 1946-08-08
Abstract: 614,869. Control of D.C. motors. BRITISH THOMSON - HOUSTON CO., Ltd., and LESTER, F. D. Aug. 8, 1946, No. 23536. [Class 38 (iii)] A rheostatic braking system for electricallypropelled vehicles employing compound wound motors has a contactor for cutting out a resistor in the shunt field circuit, thus over-exciting the field during the braking period while the vehicle is still in motion, the contactor becoming deenergized when the vehicle speed falls to a predetermined low value, thereby re-inserting the resistor and reducing the field excitation. During acceleration contactors 1, 2, 3 are closed and the starting resistor A is cut out in steps. During rheostatic braking contactors 1, 2 are opened and contactor 4 is closed, thereby connecting the motor armature D across the resistor A. Contactor 5 is closed to excite the shunt field C and contactor 6 is closed to cut out resistor B, thus over-exciting the field C. The operating coil of contactor 6 is connected, during braking, across the motor armature, e.g. at points X, Y between which, when the vehicle speed is low, the difference of potential is very small. Contactor 6 is thereby deenergized and the excitation of the field C is reduced.
