Abstract: A photographic camera (10) having a mechanism for alleviating the effects of curl due to filmstrip (14) core set in a film cartridge (12) caused by aging and/or elevated temperatures. Curl in the filmstrip (14) is detected or calculated from sensed conditions, and the filmstrip is flattened out in the exposure space gate (22) of the camera in response thereto so that the camera is able to optimally focus an image of an object on the entire flat image receiving surface (20). Adjustment of the gap in the space gate may be accomplished by mechanically detecting the diameter of the filmstrip wound about the take-up reel with a film follower roller (30) or may be electronically approximated by a microprocessor processing signals reflecting the manufactured date of the film cartridge, the total number of potential image frames of the filmstrip in the cartridge, and the current exposure frame number to estimate the amount of core set and adjust the space gap accordingly in an automatic exposure control camera. Optionally, the ambient temperature and/or humidity may also be sensed by sensors and used to derive the space gate gap. Mechanical levers 32 and ramps (41, 44; 42,46) or pivots or a spacer bar or and electromechanical device may be employed to adjust the space gate gap under control of the film follower roller or the microprocessor. The camera lens may be adjusted along with the space gate gap to adjust the lens focus.

Abstract: The space requirement of a mortise lock for an outer door depends, above all, on the spindle dimension (37) and on the handle spacing (36). On the other hand, lock cases (1) of different sizes are required and are produced. The size of the drive for a latch (2) and a bolt (3) of such a lock therefore determines the minimum size of the lock case. Furthermore, there are versions for an only single locking of the door relative to the fixed frame, with only one bolt (3) of the lock, or multi-point locking by the use of push rods (74, 75) with locking members attached thereto. In the case of both single locking and multi-point locking, opening and closing and the securing of the closing position must be possible by means of a key inserted into a lock cylinder. Instead of closing via the key, closing can also take place via a handle which is drive-connected to a handle follower (5). The latch (3) can be actuated via the handle follower (5). In order to meet all these requirements, there is inserted into the lock case (1) an intermediate case (32) having a built-in unit (31, 39, 40) which is designed according to the particular needs. This also includes a two-part reversing device (17, 28), the upper part (17) of the reversing device, connected in an articulated manner (30) to the lower part (28) of the reversing device, being mounted rotatably on the handle follower (5). <IMAGE>

Abstract: An air percussion hammer drill is disclosed for operation in an earthen formation. The air compression hammer mechanism comprises a piston that reciprocates while simultaneously rotating within its housing. A hammer drill bit slidably keyed to the bottom of the piston transfers the impact energy to the formation and rotates during operation independent of an attached drill string. The air percussion hammer assembly is therefore ideally suited to directional drilling activities.

Abstract: In a rotary haymaking machine with a plurality of working rotors connected releasably to a machine frame (1), the object to be achieved is to mount the working rotors with as little play as possible in a particularly bend-resistant and therefore vibration-free manner, without impeding the possibility of adjusting the angular position of the running wheels. Moreover, the drive housings are to be capable of being sealed off without a gap against dust and lubricant. The object is achieved in that the working rotors are mounted on tubular sleeves (4) which are screwed to the machine frame (1) by means of a funnel-shaped flange (8) and through which pass adjusting shafts (21) which are connected at their lower end to parts (25) of a supporting mount for the running wheel and which, at the upper end, engage around a driveshaft (27) at a distance in a hook-shaped (26) or annular manner and are rotatably mounted above the latter in the machine frame (1). The play-free mounting makes it possible to seal off rotating drive parts (13, 14) of the working rotors relative to the casing (19) of the machine frame (1, 2) by means of an annular gasket (18). <IMAGE>
