An apparatus for forming a beam includes a housing, electromagnetic coils and/or electrostatic devices for combining a plurality of individual beams into a single beam. Deflection mirrors can be used to deflect the combined beam in a predetermined direction. The beams so combined can include beams of a constant wave or beams in pulse formation. The electromagnetic energy may include visible and non-visible rays, infrared rays, as well as particles. Laser beams can be used employing CO2 X-rays, a...

There is disclosed a beam structure for supporting a floor or roof. The beam is of V-shape cross-section, defining a lower apex and two upstanding side wings formed of wafer boards joined together at the apex by a coating of resin, in which is embedded, between the panels, a continuous tension-resisting cable. Compression-resisting strips are secured to the outside of the panels along their top edges. These strips are also made of wafer boards and serve to receive screws for securing the beam to...

A simulated beam construction comprises a rectangular elongated core member with several laterally arranged prongs or barbs. Wooden, laminated wooden or plastic planks with a lateral channel are fitted closely together and adapted to receive one of the barbs for the anchoring of the planks along the core member. Two L-shaped planks are arranged on opposite sides of the extrusion member such that the horizontal legs abut each other and cooperate with the other laterally arranged planks to enclose...

An improved beam deflector having a first ball element attached to a second ball element with the first ball element mounted in a movable socket, movable about a single axis only through the first ball element. The second ball element is mounted in a fixed socket and is rotatable about a single axis only through the second ball element. The fixed socket is fixed to the housing of the beam deflector. Rotational movement is limited by the spacing between opposing flat surfaces of the movable and f...

A reference beam detector according to the invention can be used to accurately and efficiently perform a level shifting operation by means of a reference beam and effectively eliminate the use of markers and other devices that are structurally simple but entail cumbersome operations and also the use of a level shifter. The beam detector comprises a detector main body having a beam receiving section for detecting an emitted laser beam, a display section for displaying the position of receiving th...

A brake beam assembly comprised of a compression member with a first end and a second end, a tension member with a third end and a fourth end, a strut connected to the tension member and the compression member, a first brake head, and a second brake head. The ends of the compression and tension members each contain at least two holes in which is disposed a fastener. At least one of the ends of the compression member and the end of said tension member is contiguous with each of the first brake he...

A brake beam assembly containing a compression member, a tension member, a strut connected to the tension member and the compression member, and two brake heads with recesses. The ends of the compression member and the tension member are disposed within the recesses of the brake heads together with at least one fastener per recess; and each of the fasteners is substantially perpendicular to the tension and compression members.

The heat transmission from the heating box of a spinning beam to the nozzle package carried therein in a nozzle throat is improved in such a way that the fixing device for the package is provided with heat receiving elements. These elements are subjected to saturated vapor in operation and are provided with condensation surfaces so as to receive heat from the saturated vapor. The heat received is transmitted to the package via at least one heat bridge.

A strengthening member consisting essentially of a bent sheet metal channel with opposing side walls which are provided with stiffening profiling. The profiling forms a uniform pattern of closely spaced indentations (6) separated by intermediate surface regions (7), which pattern extends along each channel wall (2), both the indentations (6) and the intermediate surface regions (7) extending over the entire height of the wall. The channel has a bottom interconnecting the side walls, the indentat...

A bumper beam which can be formed easily by simple bending works is provided. The bumper beam is formed into a U-shaped sectional shape having a vertical wall and upper and lower horizontal walls connected to the vertical wall by bending a sheet of metal plate. Each lengthwise end portion of the metal plate is formed with upper and lower tapering horizontal wall extension parts and an intermediate part separated from the horizontal wall extension parts by cut-out spaces. The intermediate part co...
