Title: Twin lens reflex camera with pivoted blade shutter
IPC: G03B13/20
Filed: 1960-01-22
Abstract: 933,586. Photographic cameras. AGFA A.G. Jan. 22, 1960 [Jan. 31, 1959], No. 2505/60. Class 98 (1). In a twin lens reflex camera with a pivoted blade shutter in which the lenses are so closely adjacent that the shutter housing would normally obstruct the view finder beam, the shutter housing at the side adjacent the view finder objective has a recess for allowing the view finder beam to pass, into which recess the corresponding shutter blade or blades pivot in opening of the shutter. As shown, shutter housing parts 35 and 38 of a twin-lens camera, between which parts the shutter blades 33 pivot, include a recess 32 for allowing the view finder beam to pass unobscured. The shutter aperture 40 is flattened at 41, 42 to improve light proofing and, for the same purpose, a U-shaped blade spring 43 secured to housing portion 38 by screws 44 is provided with an arcuate screening flange 45 normally covering the passage 54 in which the shutter blades pivot, but moved out of the path of the blades during exposure by means of a rod 53 having projections 47 penetrating apertures 46 in the spring 43 and being coupled by way of a bell-crank lever 50 to a release pin 6. The shutter release 52 is also actuated by the lever 50. Shutter speed 10 and diaphragm aperture 9 setting rings are rotatable about the whole objective tube 8. Ring 10 is coupled by way of pin-andslot connection 30, 31 to shutter control ring 28, and ring 9 is coupled by way of fork 24 and pin 25 to diaphragm control ring 26. Rings 9, 10 may be coupled together for setting in terms of light values, the control surfaces of fork 24 and slot 31 may be cam-shaped for linearizing the setting ranges of the rings 9 and 10, and the rings may be coupled in known manner with a follow up pointer or an automatic exposure regulating device. Focusing ring 11 rotatable in objective tube 8, is coupled through an intermediate ring 15 and a screw thread 19 to an axially movable objective plate 20 supporting both lenses. In modifications, rod 53 may be coupled to or spring 43 may be directly deflected by a working part of the shutter mechanism. One only of the setting rings 9 and 10 may be provided on the tube 8, the other accommodated within the camera housing being coupled in known manner to an automatic exposure regulating device.

Title: Improvements in or relating to the balancing of rotatable containers
IPC: D06F37/22
Filed: 1962-01-23
Abstract: 922,856. Balancing centrifugal machines. WHIRLPOOL CORPORATION. Jan. 23, 1962 [March 23, 1961], No. 2517/62. Class 34 (2). Apparatus for counterbalancing a rotatable container, e.g. the spin-drier drum of a domestic laundry machine, comprises a base having a support thereon, including bearings for journalling the container, a shaft carried for rotational movement by the support, means connecting the shaft to the base and effective upon vibratory movements of the support relative to the base to oscillate the shaft, and counterbalancing means including a fluid blocking member connected to the shaft and directly responsive to rotational movement of the shaft for controlling the admission of counterbalancing fluid to the container when the vibratory movements exceed a predetermined level. In a laundry machine out of balance forces in the spin-drying operation are counterbalanced when the forces reach a predetermined level by means of water taken from the machine sump which is introduced into pockets 55, Fig. 1, of the segments 70a, 70b, 70c of a horizontally-mounted rotating drum 19 through a nozzle 95. The flow is normally interrupted by a deflector member 81, Fig. 4, controlled by a shaft 79 connected to the base 13 of the machine via a spring 85 and support member 100 secured to the base, the vibratory movements of which support member relative to the base oscillates the shaft to pivot the deflector 81. The spring 85 is clamped between a surface 100a of the member 100 and a surface of the upper end of a lever 105 pivotally connected at 106 thereto to exert a biasing force on the shaft 79 during vibration of the member 100 and so produce an oscillating movement of the shaft. A cam 83 is mounted on the shaft for rotation therewith for actuation of a bleed valvo 91 by a spring-urged arm 86 and roller assembly 87, which valve is connected through a conduit 91b to a friction clutch of the drum drive transmission means whereby increased acceleration of the drum is prevented during the off-balance period, though the clutch control and water balance systems are so co-ordinated that the fluid balancing takes place prior to clutch disengaging. The lever 105 can be pivotally swung clockwise to release the spring 85 and to permit return of the deflector to its originally indexed or zero position by action of the spring-urged cam 83. This clockwise movement can be achieved by clamping the lower end of the lever 105 to the member 100 by a spring 107 to bias the lever into clamping engagement with the spring 85, the release of which is achieved by a force either comprising a solenoid 115 and armature 115b responsive to the timing cycle of the laundry machine or a manually-operated actuating member 109 pivoted to the lever 105 and engageable in positions determined by slots 108 in the support member 100.

A file for storing embossed plastic cards or metal address plates C so that they are in visible overlapping vertical positions, comprises a tray (12) having an inclined left side wall 20 and a right side wall 24, a laterally inclined bottom 22, a series of parallel diagonal grooves 21, 25, respectively, in the walls 20, 24, and a separator element (42, Figs. 2, 11, and 12) positioned in each opposed pair of grooves to form a card retaining pocket between each adjacent pair of separator elements. The tray is preferably of moulded plastics material, and has an outer left wall 16, and two pairs of legs (26, 26) and 27, 27 on the bottom 22 for releasably retaining a stand (14, Figs. 2-4). The stand, when fitted in one position, holds the tray on a support at one inclination, and when fitted in the reversed position, holds the tray at a steeper inclination (Figs. 1 and 2). Each separator (42) is made of plastics material, and has an extended ear (46) on its left side, and a pair of spaced ribs (48) on the bottom edge (44) which provide supports for the cards (C). The separators, together with the sloping side 20 and bottom 22 form pockets inclined to the left so that cards are inclined correspondingly, each card, Fig. 7, can be tilted to the right to facilitate removal. The ears (46) of the separators can be differently coloured for reference purposes. Two trays (12) can be releasably secured together, side by side (Fig. 10), by providing grooved ribs (28a, 28b, 28, 30) on the sides so that they can be joined by a longitudinal sliding movement. In a modification (Figs. 9 and 10), pairs of trays joined together, side by side, are releasably pivoted at their front ends in a base (B) of moulded plastics material which comprises a corrugated bottom support which is slotted (90, 94 &c.), to receive feet (40) on the trays. Thus each pair of trays rest on a sloping face of the bottom support, and can be swung forward to allow access to the next pair.
