Title: Beam-guidance in electron beam welding - avoiding phase-displacement between the deflection current and resultant magnetic flux
Inventor: ORLOV ALEXEI MIKHAILOVICH
IPC: B23K/
Filed: 1975-02-04
Granted: 1979-03-10
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: System and method for the production of reinforced- concrete products with a complex cross-section
Inventor: SUBACCHI ALDO
IPC: B28C/
Filed: 1990-03-23
Granted: 1994-05-18
Abstract: For the production of reinforced-concrete products with a complex cross-section, for example roof slabs with a Y- shaped cross-section, a system is used, comprising a structure which moves along the formwork where the slab is cast and which comprises a hopper discharging the concrete, a metering element which consists of two concentric screw feeders running in opposite directions and which smoothes the concrete so as to leave inside the formwork the exact volume necessary for forming the product, a shaping screw feeder which distributes the concrete along the whole surface of the formwork and a vibrating plate for the finishing operations. It is therefore possible to cast the entire product with one continuous casting of concrete, without interruptions and with completely automatic operations.

Title: Pipes clamp on coupling arrangement
IPC: F16L/
Filed: 1977-08-04
Granted: 1985-05-25
Abstract: Pipe coupling comprises two tubular parts each having a flange at one end, a clamping ring with an internal groove adapted to receive the flanges when the two tubular parts are disposed in end to end relationship with their flanges together. The coupling includes an annular seal adapted to provide sealing between the tubular parts.

Patent PT-75330-B (PT)
IPC: A47C3/026
Filed: 1982-07-27
Abstract: A reclining chair is disclosed containing a conventional seat portion pivotable about a fixed pivot shaft or axle and a backrest containing a backrest plate displaceable upon guide rails. These guide rails are pivoted to a greater extent than the seat during the rearward reclining of the seat, due to the action of a guide element connected with a piston rod of a pneumatic spring arrangement. Due to the movement of the guide element there is rotated a transmission lever pair about a stationary pivot shaft, the transmission lever pair being connected with the guide element. A curved entrainment member, hingedly connected with this transmission lever pair, is connected with the backrest plate. Since a pivot shaft between the transmission lever pair and the curved entrainment member moves through an appreciably larger distance than the connection location between the seat and the guide element or the guide rails, the backrest plate is downwardly drawn along the guide rails. By virtue of this adjustment mechanism there is ensured that the backrest plate follows that course of movement which is performed by the back of the user during reclining of the chair.
