Title: Monitoring facility for electric welding equipment, in particular as used for metal box manufacture
Inventor: PAZZAGLIA LUIGI
IPC: B23K11/25
Filed: 1987-06-18
Abstract: The invention relates to the art field of resistance welding utilizing rollers (1) in conjunction with a continuous copper wire electrode (2) and effected with welding current (Is) that remains constant on average, at least within each half-period. According to the invention, the weld between members (3, 4), generally tinned metal strip, can be monitored by measuring the current (Im) that flows through the circuit (2a) created by the electrode wire (2), this being a function of the welding resistance (Rs) that registers between the rollers (1); the value of the current (Im) thus measured is compensated in respect of the inductive effects produced by the magnetic field originating from the welding current (Im), and relayed in digital form to a microprocessor (5) that compares it with given maximum and minimum limits within which the reading must fall for quality of the weld to be assured.

The number of consecutive bits of the first logic value is at least equal to P. The number of consecutive bits of the second logic value ("O") is at least Q, P being an integer greater than or equal to 1 and Q being an integer greater than P. The code words are selected in such a way that for information words of successive values the associated code words differ for only one bit.

Abstract: A device for lifting and tilting a vehicle from a standing position directly on a floor or ground surface to a tilted position on one side of the vehicle. The device includes at least two bearer members (174) which include an arcuate support base (180) with an abutment surface for contacting the floor during tilting rotation along a substantially vertical plane. A mounting plate (234) is configured for direct attachment to extending lug bolts (230) from a wheel-mounted hub (227). Coupling jaws (184) are provided for rigid, detachable mounting of the bearer members (174) to the mounting plate. An elongated, interconnecting, rigid support structure (47) is secured to each respective bearer member (174) to form a single, rigid cradle support for one side of the vehicle. A tilting system is coupled to the cradle support and includes a tying member (45) which joins the tilting system to the cradle support. The tilting system includes a lifting member (37), a base support member (21), and a hoist member (85). These are interconnected in such a way that the lifting member is rotationally coupled at one end of the base member, permitting the remaining end to be raised to a tilted configuration in response to lifting forces applied by the hoist member (85). This system enables a single person to tilt a heavy vehicle onto its side, removing the tilting system to leave the vehicle in a stable tilted position.
