Abstract: An endoscope ocular device (1) comprises a hollow cylindrical housing (2) and a return ring (28) which is ro- atably mounted on the housing (2), and rotated with a photographic camera (106) fixed in place, whereby adjust- ng an ocular (12) to a prescribed dioptric position, no natter how the ocular (12) was previously disposed. A contact chamber (60) is provided between the return ring (28) and housing (2). Provided in the return ring (28) is a first contact (43), one end (44) of which is exposed to ihe outer periphery (45) of the return ring (28), and the other end (46) of which projects into the contact chamber (60). Provided in the contact chamber (60) is a second contact (47) which is removed from the first contact (43) when the photographic camera (106) is taken off, and connected to the first contact (43) when the photographic camera (106) is fixed in place, and is also connected to an electric power source (113). That end (44) of the first contact (43) which is exposed to the outer periphery (45) of the return ring (28) is accessible and can be cleaned with water quickly and reliably. Where the photographic camera (106) is taken off the ocular device (1), the first contact (43) is disengaged from the second contact (47). Therefore, the operator who happens to touch the exposed end (44) of the first contact (43) is not subject to an electric shock.

Abstract: The invention relates to a process for inhibiting the corrosion of an installation, made of a material chosen from amongst the metals which are less noble than hydrogen, and their alloys, in contact with an acid bath containing an alkylpyridinium chloride. A soluble cyanide complex, which is capable of forming an insoluble compound by reacting with ferric ions in the bath, is added to the bath so as to limit the concentration of the ferric ions in the bath to a maximum of 30 mg/kg. The content of ferric ions in the bath is controlled by means of a potentiometric measurement so as to bring the potential of the bath into the region of a predetermined value. The invention applies in particular to the treatment of baths for cleaning or descaling steel installations.

Abstract: The guiding apparatus comprises substantially rectangular rail holders and L-shaped rail holders. Main and follower travel rails or tracks are supported by such rail holders and there are provided side plates at which there are mounted the rail holders, the side plates being supported upon a carrier frame. These rail holders are provided at their attachment or fastening side with at least two respective centering protuberances or nubs or the like which engage into corresponding centering openings provided in the side plates to which the rail holders are fastened. The rail holders possess, at their rail contact side, a dovetail clamping device which, in cooperation with a dovetail profile or section extending along the underside of the travel rail or track, to reliably and easily releasably holds the travel rails and the rail holders by virtue of a clamping action which is exerted at all sides of the dovetail profile. The side plates, and, in particular, the position of their centering openings are produced true or exact to size and with narrow tolerances so that in cooperation with the related centering protuberances and the rigid dovetail clamping there is automatically ensured parallelism and alignment of the travel rails or tracks required for a quiet escalator or stair running. The guiding apparatus can be assembled without the need to resort to assembly fixtures or jigs and without subsequent adjustment from individual mass-produced parts.

Abstract: The machine for the manufacture of cams from sheet metal has a press stern (10) which is surrounded by a number of ram assemblies (11) carrying dies (12) cooperating with punches (13) attached to bolster (14) of circular shape. A cylindrical cam (21) cooperates with ram assemblies (11) through follower rollers (22, 23). The cam is driven by gears (32, 33) and a crankshaft (36). The corresponding transfer mechanism comprises a transfer ring (43) provided with three mounting pins (42), two idling arms (44) and a driving crank (41). As the shaft (40) rotates, the ring (43) gyrates about the center of the press stern (10), the two idling arms (44) always maintaining a parallel relationship to the crank (41). Six pockets (P1 to P6) are attached to the transfer ring (43) - according to Fig. 8-1 one pocket (1) collects a blank from the supply conveyor, whereas another pocket (2) makes contact with the component in the first tool (1) etc. The interaction between transfer pockets of the ring (43) and the locating rings attached to the tools (T1 to T5) ensures complete control of the components during transfer, nest means being provided at each tool including a plurality of spaced prongs cooperating with spaced fingers provided on each pocket (P1 to P6). Fingers and prongs are arranged in such a manner that the fingers of an empty pocket member pass between the prongs of the nest means and remove a component located at the tool station. The components are thus advanced from one tool station to another along a circular path, the tools being operated consecutively by said cam (21) and thereby subjected to a periodical reciprocating action.

Abstract: A clock signal regenerator comprising a frequency control loop (1, 2, 3, 4) which comprises a variable-frequency clock signal generator (2) used in digital telephone exchanges, when a local clock signal must be generated from incoming clock signals (1-1, 1-N). The clock signal regenerator comprises a very stable auxiliary signal generator (9) and a first difference signal producer (11) for determining the frequency difference between the generated clock signal and the auxiliary signal. This frequency difference is determined periodically and written into a storage device (13). In addition, the regenerator comprises a second difference signal producer (14) in which the difference is determined between a new frequency difference determined in the first difference signal producer (11) and the preceding frequency difference stored in the storage arrangement (13). After the incoming clock signals (1-1, . . . 1-N) have dropped out the difference signal produced in the second difference signal producer (14) is applied as a control signal to the clock signal generator (2), and the content of the storage device ( 13) is not changed. This has the advantage that the stability of the clock signal regenerator is then the same as the stability of the auxiliary signal generator.
