Patent DE-4102936-A1 (DE)
Title: Material processing using polarisation-modulated laser beam - altering phase difference between two orthogonal vector components of polarisation as function of time
Inventor: KEILMANN FRITZ DIPL PHYS DR
IPC: B23K26/06
Filed: 1991-01-31
Abstract: The Co2 laser (10) has a commencing power sufficient for material processing, and delivers a linearly polarised laser beam (12). The laser beam passes through a phase modulator (14) and then drops via a deflecting mirror (16) into a laser head (18) forming part of a robot. The laser head contains two deflecting mirrors (20) and a focussing lens (24). One deflecting mirror (20) is rotatable around an axis (26), and the other is rotatable with the focussing lens (24) around a further axis (28) in order to achieve a desired orientation of the focussed laser beam. In practice, normally several rotatable located deflecting mirrors and several degrees of movement freedom are provided. The focussed laser beam drops on to the upper surface of a workpiece (30) arranged on a support (32) with which it is movable in a specific direction (34) in relation to the focussed laser beam. A modulator (14) is also provided for the polarisation condition of the laser beam. ADVANTAGE - For material processing by laser beam, the polarisation of which is modulated.

Patent DE-4106421-A1 (DE)
Inventor: SCHELLE AXEL DR
IPC: B61G5/08
Filed: 1991-02-28
Abstract: The automatic coupling for rail vehicles has a line coupling head 1 which is located at the front and can be pressed back in a resilient manner. In order to support the pneumatic sealing support of the line coupling a short-stroke cylinder 5 is provided whose piston 6 is coupled to the line coupling head 1 and whose cylinder body 7 is held so as to be displaceable element relative to the line coupling head 1. When the short-stroke cylinder 5 is subjected to pressure, as a result of the relative displacement of piston rod 8 and cylinder element 7 an angular lever 14 which is rotatably mounted on the cylinder element 7 is rotated in such a way that one of its legs 18 comes to rest from the front against a stop face 20 of the coupling head and thus blocks the cylinder element 7 against rearward displacement. The force resulting from the subjection to pressure medium of the piston 6 is then transmitted as forwardly directed force on the line coupling head 1, as a result of which the pressure and thus the seal of its coupling sealing ring with respect to the corresponding line coupling head is supported. <IMAGE>

Patent DE-4115606-A1 (DE)
Inventor: BENCKERT HARTMUT DR ING
IPC: F04B49/10
Filed: 1991-05-14
Abstract: In a hydraulic pressure generator with a main pump driven by a diesel engine, a main user circuit connected thereto is formed by a setting choke (18) directly connected to the main pump and a user (11) connected in series thereto. By comparing the output pressure PH coupled in a first control chamber of a control valve (31) with the comparison pressure PV which can be detected at the main user (11) and coupled in a second control chamber (37) of the control valve (31), the control valve (31) controls an adjuster (21, 22) in such a way that the flow volume in the main user circuit (16, 11) remains constant. A protective device designed to prevent the diesel engine (13) from stalling under extreme load comprises an auxiliary pump (42) driven with the engine which generates a rotation-speed-proportional output flow volume which passes through a further adjusting choke (46) and a synchronous-revolution user (44) downstream thereof and a pressure-controlled valve (47) via which the second control chamber (37) of the control valve (31) relieves pressure towards the tank (32) and thus sets the main pump (12) to the minimum volume conveyed if the motor speed falls below a threshold.

Title: Shooting weapon (firearm) for cartridge ammunition
Inventor: KEPPELER DIETER
IPC: F41A21/12
Filed: 1993-03-03
Abstract: In order to accommodate, in particular, large-calibre cartridges, the shooting weapon has a firing chamber which is arranged partially in a breech part and partially in the weapon barrel, coaxially with respect to the barrel bore. While the large-volume part of the firing chamber is located in the breech part, that part of the firing chamber which accommodates the smaller case neck and the cartridge shoulder is arranged in the rearward end of the barrel bore of the weapon barrel. In consequence, there is no need to enlarge the barrel diameter as a result of the larger firing chamber in the case of large-calibre shooting weapons, as a result of which it is possible to avoid increasing the weight of the shooting weapon.
