Patent DE-3215611-A1 (DE)
Title: Device for measuring the polarisation of a laser beam having a high continuous wave power
Inventor: BRANDT DIETER
IPC: G01J4/00
Filed: 1982-04-27
Abstract: During material processing (machining) with high-power lasers, it is important to know the polarisation properties of the laser beam as well as the radiated power. In the case of the high powers which are normal in this field of application, the known devices are largely incapable of polarisation measurement. The device according to the invention makes use of the fact that the reflection of a metal surface is heavily dependent on the polarisation direction of the radiation when said radiation is incident virtually tangentially. Metal surfaces of different design are thus placed in a laser beam such that the reflection of this beam on them takes place virtually tangentially and such that the portion of radiation thus reflected strikes a receiver. The overall arrangement is designed such that it can be rotated about the beam axis. A change of polarisation direction and polarisation intensity can be measured during rapid rotation about this axis. If a plurality of receiver elements are used, the spatial structure of the intensity and polarisation of a laser beam can also be determined.

Title: Copying lamp
Inventor: JAHN JOERG
IPC: G03B27/16

Abstract: The invention relates to a copying lamp for exposing, particularly for graphics purposes, materials that are sensitive to UV radiation and are arranged on a flat copying surface, having a metal halide burner as radiation source, a shutter arranged upstream thereof, and a reflector which preferably consists of high-purity aluminium. The arc of the radiation source (9) is located between the focal point (14) and the apex of the approximately cylindrically shaped reflector (16), and the reflector (16) is - seen in the cross-section perpendicular to the longitudinal extent of the radiation source (9) (XZ central plane) - is constructed as a parabolic or circular segment having a secant (18, 19) adjoining each side relative to an axis (17) of symmetry in such a way that the reflected radiation of one reflector half impinges on the respectively corresponding half of the copying surface located there below, the angle of incidence of each reflected beam (angle between beam and normal to the reflecting surface) at the copying surface (20) being always equal to or less than the angle of incidence of each direct beam on the copying surface (20). The surface normals of the reflector surfaces (20a-d) above the XZ central plane relative to the surface normals (22) of the reflector surfaces (24a-d) extend divergently at an acute angle below the XZ central plane. <IMAGE>

Title: Vacuum cleaner
Inventor: STETTNER GERHARD DIPL ING
IPC: A47L9/24
Filed: 1982-06-01
Abstract: A vacuum cleaner with a suction pipe nozzle (5) and a socket (14) provided on the housing (1) is connected to a suction hose (7) which can be connected by a connector piece (9) to the suction pipe nozzle (5) and can be connected to the socket (14) via a plug (15) arranged on a flexible electric cable (13). In order in this case, with largely free mobility of the suction hose (7) relative to the housing (1), to achieve favourable guiding of the cable length required for said mobility during operation, the suction pipe nozzle (5) is angled and is inserted with one end rotatably into the upper side wall (3) of the housing (1). Additionally, the socket (14) is arranged behind the suction pipe nozzle in the main direction of movement of the housing (1) and the cable (13) is guided away from the connector piece (9) in the direction of the suction hose (7). Consequently, the cable (13) runs back to the socket in a curve extending over about 180 DEG . <IMAGE>

Title: Gasket, especially cylinder head gasket
Inventor: MAJEWSKI KLAUS-PETER
IPC: F16J15/12
Filed: 1982-07-16
Abstract: Gaskets, especially cylinder head gaskets, are provided on their sealing surfaces with films of synthetic resin and/or elastomers on one or both sides, which may have, if required, fibre reinforcements and adhesive coatings on one side and/or a one-sided release coating on the other side. The films are preferably up to 0.4 mm thick. The synthetic resin and/or elastomer components are not crosslinked to their limit and can thus be plastically deformed under pressure, so that the gaskets optimally adapt to the sealing surfaces of engine block and cylinder head upon installation. In addition the films can be drawn as a border over the sealing edges and/or they can be folded so as to be superimposed on each other in certain regions, so that with the application of the films adequate edge protection as well as zones of increased sealing pressure are formed simultaneously. <IMAGE>

Title: Window protection
Inventor: BRESSLEIN HELMUT
IPC: E06B9/24
Filed: 1982-10-22
Abstract: In comparison with the known roller shutters and roller blinds, the invention has the advantage that energy is saved even during the day, protection is afforded against heat and noise with full visibility, and a curtain effect is provided.

Filed: 1983-07-05
Abstract: Axes X', Y' and Z' of a resonator are established from the axes X, Y and Z of a quartz crystal by virtue of two rotational movements through angles  phi  and  theta , respectively. The resonator is energized to vibrate in accordance with the fundamental torsional mode. The angles of cut  phi  and  theta  are such that the first-order temperature coefficient is zero. The torsional mode may be coupled to a flexural mode in order to render the second-order temperature coefficient zero. The fork tines extend in the X' direction. In other embodiments the tines extend in the Y' direction and the rotation  phi  and  theta  are about the X and Z' axes, respectively.

The deflection device can be attached at any point of the rope. The suspension member can easily be pushed into the receiving opening of the hook body in order to secure the deflection device. Due to the different cross-sectional design, the suspension member is secured against unintentional unhooking.
