Title: Improvements in photoelectrically controlled diaphragm mechanism for photographic cameras
IPC: G03B7/12
Filed: 1939-07-28
Abstract: 531,667. Controlling exposures in photographic cameras. SCHMIDT, W., and DECKEL, F. July 28, 1939, No. 22005. Addition to 507,486. [Class 98 (i)] The diaphragm aperture in a photographic camera is controlled by a photo-electric cell operating to adjust in the path of a coupling a member whereby the coupling is disengaged when it reaches the adjusted member, the aperture produced by manual actuation of the diaphragm mechanism being determined by the distance through which the coupling travels before disengagement and the coupling being put wholly out of action by a dial of the photoelectrically adjusted member. As shown, depression of the button 30 causes the drum 54 carrying the armature 20 to be locked by the brake blocks 52, 53 in the position to which it has been rotated between the poles of a permanent magnet by the current from the photo-electric cell 21, the position . being indicated by the pointer 56, and further depression of the button 30 rotates the pinion 64 through the linkage 41, 60 and moves the piston 71 outwardly in the cylinder 70 by engagement of the pinion 64 with the rack 69. The rack also operates the iris diaphragm 110 by the linkage 79a, 106. When the pin 68 on the slide 65 strikes the nose 57 on the drum 54 the tooth 66 is disengaged from the notch in the pinion 64, and the spring 75 moves the rack back at a very slow rate determined by the vent 73 to reclose the diaphragm. The rate of closure is so slow that the required aperture is preserved for the time necessary for making the exposure. The button 30 may also actuate the shutter after adjustment of the diaphragm aperture. Specifications 453,334 and 489,228, are referred to.

Title: Electric lamp with integral plastic base member, and method of assembly
IPC: H01R33/09
Filed: 1969-05-01
Abstract: 1,209,282. Electric incandescent lamps. WESTINGHOUSE ELECTRIC CORP. 1 May, 1969 [13 May, 1968], No. 22219/69. Heading H1F. [Also in Division H2] The envelope 18 of an incandescent lamp has a sealed end portion 17 which terminates in an enlarged globule 29 defining a shoulder 30 and a transversely extending recess 31, the envelope being secured to a plastics base member 32 which comprises a cylindrical collar 38 surrounding the bulbous part of the envelope, a cavity 33 receiving the sealed portion 17, and a rectangular boss 34 which has a permanent keyed connection with the shoulder and the recess. The base member is adapted for mounting the lamp on a printed circuit board 52 and for this purpose is provided with a pair of diametrically opposed lugs 40 designed to effect a cam-locking action with the upper surface of the board, a laterally projecting flange 42 designed to abut the lower surface of the board, and a pair of contactor members 44 (Fig. 6) each of which has an arm 49 terminating in a rounded end segment 50 designed to effect electrical engagement with conductive elements 54 on the board. Each contactor 44, which is made of resilient sheet metal such as hardened brass, s anchored in a channel 35 in the boss 34 by means of a laterally projecting tongue 46 and has a narrow end segment 48 which extends through an opening 37 at the bottom of the channel into a rectangular slot 36 at the end of the boss where it is joined to the corresponding lead-in conductor 26 by spot-welding or soldering. The end of the envelope may be embedded in the plastics material of the boss 34 by heating the material to cause local softening and forcing the globule 29 into the boss so that the softened material flows into the recess 31. The heating may be produced by sharply defined fires or by vibrating the boss at a frequency of at least 1000 c.p.s. using a suitable transducer. When the base member is composed of asbestos-filled extrusion-grade polypropylene having a softening point of 225 F. the embedding of the envelope can be achieved in 1À2 seconds using vibrations at 20,000 c.p.s. In a modification (Fig. 8, not shown) the boss (34a) has a flat end face and the protruding ends of the lead-in wires (26a) and the segments (48a) of the contactors (44a) are protected by a plastics end cap (56) which is fused to the boss by vibratory energy. In a second modification (Fig. 12, not shown) the boss is omitted and the end of the envelope is embedded in cement (64) located at the base of the cavity (33b) in the base member. The lead-in wires can be maintained in engagement with the contactors by forcing them into blind channels (35b) in the base member, the contactors being optionally formed with U-shaped portions (51, Fig. 13, not shown) in which the lead-in wires (26c) are clamped. In a further modification (Fig. 14, not shown) the contactors (44d) have the form of rivets with heads (66) adapted to engage the printed circuit board.

[Class 83 (iv)] In a process for reducing or eliminating internal stresses set up in metal articles due to cold working, the articles are subjected to a further cold working operation producing a smaller reduction in cross sectional area than the first operation, whereby the stresses set up by the second operation counteract those produced by the first operation. In an example, steel rods are cold drawn with a reduction in area of about 8À5 per cent and are then re-drawn with a reduction of less than 1À5 per cent, preferably about 0À6 per cent. The articles may be subjected to further operations producing small reductions in area, and in drawing, the operations may be performed in one stage by arranging the successive dies in a series.
