Title: Photogrammetric stereoscopic affine plotting machine
Inventor: HOFMANN OTTO
IPC: G01C11/00
Filed: 1968-09-30
Abstract: 1, 245,252. Photogrammetry. O. HOFMANN. Sept.30, 1968, No.46385/68. Heading G1F. A photogrammetric plotting machine with opticomechanical projection is provided with a mechanical system for compensation of image tilt and incorrect photographic distances caused by differences in the focal length of the camera with which the photographs were taken and of the optical plotting system, the photographs being maintained in a horizontal position. Fig. 3a represents one side of the machine for viewing one photograph 39 of a pair by means of a binocular viewing system with lenses 11, prisms 11b and viewing marks 11a, and also comprises a guide rod 9 carried by gimbals 8, 10 and 15, the gimbal 15 being attached to the plotting carriage. The effective length of the rod 9 may be adjusted by means of a vertically adjustable slide 7. The gimbal 10 connects with a carriage 32 which is guided for vertical movement in guides 47, 48 relative to the main photo-carriage 12, but transmits horizontal movements thereto. A crossslide 36 on the carriage 32 and this carries a feeler head 35 which engages with a plate 33 on a guide rod 31 moving in a guide sleeve 30, the plate 33 being inclinable in all directions about a pivot point 34. Thus horizontal movements of the carriage 32 cause tilting of the plate 33 and in this way produce vertical movement of the carriage 32 to the extent provided by contact of the feeler head 35 with the plate 33 under the action of springs 49, 50. The feeler head 35 may be spherical or may be not spherical but rotationally symmetrical to correct for distortion errors in the photographs, due to distortion caused by the objective of the taking camera and earth curvature. The carriage 32 is coupled to a guide sleeve 37 moving on a guide rod 46 universally mounted at 45 and whose effective length can be adjusted by means of a vertically displaceable guide 44. The guide rod 46 transmits its movements by way of a gimbal 38 to an intermediate carriage 41 which is free to move horizontally with respect to the carriage 12. The photograph 39 is mounted in position on the intermediate carriage 41 and is pre-set in position by means of guides 60. Thus there is superimposed on the normal horizontal plotting movements of the carriage 12 further horizontal displacements of the photograph 39 to correct for the errors referred to above. In an alternative embodiment, the error correcting movements are applied to the optical viewing system for the photograph rather than to the photograph carriage, and since the photographs are retained in a horizontal system, the machine may be adapted for producing orthophotographs. An optical scanning system in conjunction with a slit diaphragm moving over a photographic film disposed on a cylindrical member is used in this case.

Title: Improvements relating to operating mechanism for electric circuit-breakers
Inventor: HOFMANN WERNER KARL MARTIN
IPC: H01H3/30
Filed: 1966-10-24
Abstract: 1,135,250. Electrically released switches; actuation of switches. A. REYROLLE & CO. Ltd. 12 Oct., 1967 [24 Oct., 1966], No. 47663/66. Heading H1N. A trip free spring-operating mechanism for a circuit-breaker is arranged so that slow opening or closing of the contacts during spring charging is positively prevented. The mechanism is of the kind in which a closing spring 40 is charged and then released to close the contacts and charge an opening spring 15 through a collapsible force-transmission linkage 25, 26, subsequent release of the linkage allowing the opening spring 15 to open the contacts. The closing spring 40 is charged through a lever 45 by an hydraulic actuator 63 and latched by latch 48. The actuator 63 has a piston 61 coupled to a drive member 47 by a toggle link 69 such that the member 47 is biased either upwardly or downwardly from the position shown by a toggle spring 72. The drive member 47 cooperates with a roller 91 on lever 45 and is shaped so that the reaction force between them has a component urging the drive member 47 downwards. From the open position shown with both opening and closing springs 15, 40 discharged the spring 40 must first be charged by operating a valve 66; the piston 61 moves to the right, turning lever 45 about its fixed pivot 46. By the toggle 69 and the reaction at roller 91, drive member 47 is urged downwardly in engagement with a roller 85 preventing movement of a rod 80. At the end of the charging movement a lever 49 is engaged by latch 48 to retain the spring 40; limit switches release the actuator 63 and drive member 47 moves back. The initial reverse movement relieves the reaction at roller 91 and member 47 is thrown upwardly clear of the mechanism by the force of a spring 35 acting through the roller 85; torsion springs 98 assist this action. The spring 35 moves roller 85 to reengage with lever 45; collapses toggle links 25, 26 to the right and turns a lever 28 about 29 to engage with a second latch 30. The contacts can now be closed by releasing a latch 48; spring 40 drives lever 45 to draw the roller 85 and rod 80 to the left, moving toggle links 25, 26 overcentre and turning shafts 10, 11 to close the contacts and charge spring 15. The overcentre toggle 25, 26 retains the contacts closed until released by latch 30. With the contacts closed spring 40 can be recharged. If the toggle 25, 26 has failed to pass overcentre, slow opening which would otherwise result is prevented since member 47 bears down on roller 85 preventing collapse of the toggle. From the open position slow closing due to the failure of latch 48 is prevented since the reaction at roller 91 is not released and therefore member 47 continues to bear on roller 85 until spring 40 is discharged and the mechanism cannot reset for closing.
