Patent DE-2432794-A1 (DE)
Title: Lens changing device - has additional transporting component to fix or free objective in one movement
Inventor: ROEDER HORST DIPL ING
IPC: G02B7/16
Filed: 1974-07-08
Abstract: When the additional transporting component is turned a about its axis a pairing of one of four rolls and the stop cam eases the objective from the camera lens holding part, without any force re-acting upon the latter. By further turning of the transporting component the form of the stop cam ensures that the action is from the lens holding part until the next roll on the rim of the component engages with the cam. The action is then in the opposite direction, towards the camera lens holding part, to couple the next objective. A spring effects a firm coupling between the stop cam and the engaged roll as well as ensuring a definite positioning of the transporting component when no roll is actually coupled with the cam.
Patent DE-2437760-A1 (DE)
Title: Multi- axle vehicle suspension - with sliding axle fittings on leaf springs to eliminate uneven loading

Title: Beam-guidance in electron beam welding - avoiding phase-displacement between the deflection current and resultant magnetic flux
Inventor: SCHAPOWAL WLADIMIR IWANOWITSCH
IPC: B23K15/02
Filed: 1975-02-06
Abstract: Process for guiding the electron beam onto the joint between two parts being welded, where the current (I) in the deflection system is sinusoidal; the beam is moved like a pendulum over the joint; and the sec. emission signal is displayed on a cathode-ray tube, with time-base proportional to current (I), and used to displace the beam w.r.t. the joint. The novelty is that the signal is deflected on the screen of the cathode ray tube w.r.t. time so the amplitude of the time-base voltage or current is proportional to current (I), and in the region of max. current a phase reversal occurs for the voltage or current; and the two displays of the signal thus obtd. are merged by moving the beam w.r.t. the joint. The pref. device is included in the claims. The phase-displacement between current (I) and the magnetic deflection flux does not influence the guiding of the beam.

Title: Adsorption beds protection by prefilter - which is bypassed normally but put on stream if adsorbent poison detected
Inventor: WINTER KARL DIPL PHYS
IPC: B01D53/02
Filed: 1975-07-05
Abstract: The air or gas stream normally bypasses the prefilter and fuels directly to the main adsorbent bed. The flow is constantly monitored and if impurities are detected, then the bypass is closed and the flow diverted through the prefilter to remove the poisoning impurity. The pressure of the impurity can be determined by means of IR or UV spectroscopy, flame ionisation detector or heat rise on combustion. When the concn. exceeds a certain value, the bypass is automatically closed and vice versa. Alternatively a manual reset can be included for reopening the bypass. Method is used where a toxic material is being removed from an airstream and where additional components can cause poisoning and fouling of the adsorbent. Esp. for use in nuclear power plants where radioactive I2 and its cpds. e.g. CH3I are removed from the containment area of the reactor.
