Title: Photographic camera with automatic diaphragm and time settings
IPC: G03B7/00
Filed: 1965-12-17
Abstract: 1,093,235. Photo-electric control of camera. exposure. PRONTOR-WERK ALFRED GAUTHIER G. m.b. H. Dec. 17, 1965 [Dec. 28, 1964), No. 53674/65. Heading G2A. A photographic camera is provided with one or two photo-electric cells for automatically controlling the settings of diaphragm and exposure time, and with two electronic circuits, the first for controlling the diaphragm setting and the second for controlling the exposure time setting, the circuits being arranged so that the diaphragm is wholly or partially set before the second circuit begins to function. The camera has provision for manual over-ride of the automatic setting mechanisms. In the diaphragm and shutter arrangement shown, depressing the camera release 6 when making an automatic exposure, causes the diaphragm setting member 1 to rotate clockwise (Fig. 1), thereby closing a switch 5, which causes an electromagnet 27 (Fig. 3) to be energized, thus locking a lever 35 in the position shown. Rotation of the member 1 also drives a cut-off device 8-9 to progressively lower the resistance of a photoelectric cell. When the operating valve, previously set through a programme (30), Fig. 5 (not shown), is finally reached, transistors (T 1 , T 2 ) conduct to energize an electromagnet 23, thereby -causing a lever 25 to engage a tooth 1c to set the diaphragm according to the prevailing light conditions. Further depression of the member 6 rotates a lever 17 allowing the shutter blade ring 13 to rotate. This movement closes switches S 2,  S 3  which in turn close a circuit to connect the cell 7 to the exposure time generating circuit, and opens a switch S 4  which in turn causes a capacitor (c) (Fig. 5) to charge. When the shutter is fully open, its driving disc 14 is held by the lever 35 until the capacitor (c) is fully charged, when, through transistors (T 3 , T 4 ), the electromagnet 27 is de-energized and the lever 35 is free to be moved by the disc 14, which rotates further to close the shutter. In another embodiment Figs. 8-10 (not shown), separate photo-electric cells (45, 46) are provided, one for each control circuit. A scale (52) Fig. 11 (not shown) and pointers may be provided in the viewfinder to show the generated diaphragm and exposure time values.

Abstract: 1358189 Axial-flow fans PHILIPS' GLOEILAMPENFABRIEKEN NV 26 Nov 1971 [30 Nov 1970] 54985/71 Heading F1C [Also in Division E2] A fan comprises generally radially extending blades each of which has a stem by which it is hingedly connected to the fan hub, the fan being provided with means for joint adjustment of the blades in axially inclined positions relative to a plane perpendicular to the fan shaft axis, the means being operable from the exterior and provided with a collar which engages the blade stems. The stem 7, Fig. 4, of each blade 5 projects through a slot 35 in a hub cover 18, Figs. 4 and 6, and is pivoted about a pin 10 in brackets 8 carried by a cylindrical hub portion 34, a spring 11 biasing the blade into a backwardly raked position. The spring action is opposed by a member 14, Figs. 4 and 5, which is axially movable along the fan shaft 3 and bears against fingers 17 on the stems 7. The rake angle of the blades 5 therefore depends on the axial position of the member 14 which in turn depends on the depth of a pair of diametrically opposed notches engaged by lugs 31. When the lugs 31 are within deep notches 29, the blades 5 are backwardly raked to provide a divergent airflow, while when the lugs are within shallow notches 30, the blades are forwardly raked to provide a convergent air-flow. A further pair of notches (not shown) afford a third position of the member 14. To change the blade rake, a button 6 is pressed to move the member 14 axially. During the initial part of the movement, the member 14 is prevented from rotating by the engagement of ribs 26 in slots 27. When the ribs 26 have disengaged from the slots 27, the bevelled end-face 24 of one of three teeth 23 strikes one of two ramps 25, causing the member 14 to bring the lugs opposite a different pair of the notches 29, 30 &c. On release of the button 6, the lugs 31 enter this pair of notches, and the inclined faces 32 or 33 &c of the notches impart an additional rotation to the member 14 to locate another of the teeth 23 opposite a ramp 25 in readiness for the next depression of the button. The fan may be of oscillating type.
