Abstract: 1498256 Automatic control of focus CARL ZEISS-STIFTUNG [trading as CARL ZEISS] 7 May 1975 [13 May 1974] 19103/75 Headings G2J and G3R A stereoscopic microscope, e.g. for surgical use, is automatically focused by a system in which a luminous area 17a is formed on the viewed object 4 at the observed point, light from this area is deflected from the respective stereoscopic paths on to separate photo-electric detectors 32, 33 in such a manner that differential signals are generated when the object is out of focus and the said differential output controls a focusing motor 40. It is explained that the reflected beams 250a, 250b move outwardly or inwardly according to whether the object is in front of or behind the plane of focus; edge stops 26, 27 arranged as shown result in this lateral displacement causing differential illumination of the photo-detectors. The area is illuminated preferably by a gallium arsenide diode 15 pulsed by an oscillator 36, the radiation being infrared. This light only is deflected by partial mirrors 20, 21 in the viewing light path. The system is balanced by a motor driven potentiometer when the microscope is initially focused by hand.

Title: Improvements in or relating to connections between pins and bores
IPC: F16D1/091
Filed: 1952-07-29
Abstract: 704,139. Securing pins &c. in bores. RING- FEDER GES. July 29, 1952 [Sept. 13, 1951; Nov. 21, 1951], No. 19168/52. Addition to 693,530. Class 80 (2) A pin is secured in a bore in a member, as described in the parent Specification, by means which are modified to allow the radial pressure of the ring spring, along the axial length of the pin, to be adjusted; the member may be, e.g. a flywheel or a ship's propeller. These means comprise either making the coned surfaces of the closed rings b, . . . g, forming the ring spring, with increasing taper along the axis of the pin a as shown, or alternatively forming the closed rings with coned surfaces having equal taper, when, by tightening a nut k, friction between the ring surfaces as the rings. are compressed axially ensures that the radial pressure of the ring b is greater than that of the ring g. In this form, the radial pressure of the ring spring may be adjusted either by decreasing and increasing, respectively, the diameters of the cylindrical outer and inner surfaces of the outer and inner rings, slightly and successively, axially of the pirn, or by making the pin or bore slightly 'cone shaped. Each ring can be constructed with two coned surfaces or the same effect can be achieved by welding. e.g. the rings, c, d together. Securing means of this type allow a connection between a pin and a bore in a member to be made with a reduced radial pressure at the cross-section of the pin most likely to fracture through fatigue.
