Title: Fast polynomial waveform generator for plotting trajectories - has series chain of digital integrators integrating in parallel
Inventor: VIAULT DANIEL
IPC: G05D3/14
Filed: 1975-10-22
Abstract: The polynomial waveform generator, for plotting trajectories, consists of a chain of series-coupled digital integrators whose number is equal to the order of the polynomial required. Each integrator consists of an adder (Sk) that adds the output of the preceeding integrator to the output of a first memory (M1). The first memory (M1) stores the output of the adder and its own output is also multiplied (Mk) with the contents of a register (R). Since all the integrating processes take place in parallel the time between successive increases to the polynomial at the output of the last stage is simple equal to the time required by any stage to integrate its input. The polynomial is therefore generated very rapidly.

Title: Ballast blocks scrap metal - has scrap stacks welded or bonded inside containers
IPC: F16F15/32
Filed: 1975-11-26
Abstract: The ballast weights for machines or similar applications can be made by stacking rectangular scrap metal plates as produced in press shops. The stack is held together by welding seams across its sides, and protected against corrosion by plastic coating. Scrap which is too small for stacking (5) is filled into a container where it is fixed by a bonding substance (4). Ballast blocks of precise weight can thus be made by using scrap metal. Concrete or other heavy waste can be used in the containers in place of metal.

Title: Automatic thread breakage detector and piecer for ring frames - transported by overhead carriage along machine sides
Inventor: GROSSI OSCAR
IPC: D01H15/013
Filed: 1976-08-06
Abstract: An automatic device for a ring frame spinning yarns from fibre having the staple length of wool or cotton, has a carriage running on overhead rails with a mechanism for locating and rejoining the broken threads, assembled in a housing, together with equipment for removing dust and waste, which is transported along the sides of the machine. A drive for the carriage is controlled in both directions by a separate unit; the carriage being slowed down and then stopped in front of the spindle with the broken threar or at the ends of the frame. A first group of two detection devices above the spindles lightly contact the threads they are monitoring, and put out a signal as they touch each thread. When a signal is omitted, an arrangements slows down and stops the carriage. A second group of three magnetic detectors is arranged with the detectors one behind the other in the direction of motion, at the height of the spindle feet. The centre detector locates the spindle and energises the leading detector of the first group in the direction of motion, and if the signal fails, indicating a broken thread, the following detector of the group of three, slows down the carriage, stops it at the spindle with the broken thread, and energises the details for locating and re-piercing the broken thread. System detects, locates and jois up the broken end automatically without the intervention of the operative. The operation takes place quickly and down time is reduced very considerably.

Title: Resistance seam welding machine using electrode rollers - suitable for cladding machine parts with wear resistant strip
IPC: B23K11/06
Filed: 1977-01-19
Abstract: Resistance-roller seam welding machines uses two electrode rollers, one of which being elastically pressed towards the other.
