Title: System for cathodically protecting a structure
IPC: C23F13/04
Filed: 1963-09-20
Abstract: A cathodic protection system for the hull 110 of a ship includes an anode 114 and a reference electrode 116, and is supplied from an A.C. source over a transformer 20, having a centretapped secondary winding, and controlled rectifiers 48, 50 which supply current to the system when transistors 62, 64 in their firing circuits are rendered conductive by a signal derived from the reference electrode 116. When the polarisation of the ship is below the polarisation of the reference electrode, the transistors 62, 64 are rendered conductive to cause firing of the controlled rectifiers, until the polarisation of the ship builds up to that of the reference electrode.

Patent ES-358381-A1 (ES)
Title: Arrangement for the optical monitoring of weft threads
IPC: D03D51/34
Filed: 1968-09-21
Abstract: As a gripper shuttle nears the end of its travel, an iron insert in the shuttle passes over a coil in the slay the resulting signal causes the weft coming from the supply bobbin to be clamped, whereupon the leading end pulls out of the shuttle and is drawn into a suction tube. A light-emitting diode inside the mouth of the suction tube shines on a photocell, the beam being interrupted by the entering weft thread. If no thread enters during a timing pulse generated by the shuttle passing the coil in the slay, the loom is stopped.

Title: Method of and apparatus for the production of tempered glass articles of channeled or u cross-sectional form and article formed thereby
IPC: C03B27/06
Filed: 1969-04-19
Abstract: Glass pieces having at least two plane sides 11 joined along an edge by a curved portion so that the plane surfaces are at an angle, e.g. a U- shaped channel piece, are tempered, after formation and cutting of the piece, by rapidly cooling the glass with a cooling medium, preferably gaseous (e.g. air), such that the highest cooling rate is at the concave (i.e. interior) surface of the angle 10, the lowest at the convex (exterior) surface, and the plane surfaces are cooled at an intermediate rate, so that the heat dissipation is uniform, giving a uniform stress distribution. A channel shaped piece may be tempered in the apparatus shown which comprises two sets of chambers 20, 21, each chamber being supplied with gas via header tubes 32, 33, and the gas being emitted through slots 26, 27 and 29. Slots 26 and 27 are narrower than slots 29: thus a higher cooling rate is maintained at the concave (interior) surface of the angle. A similar device, in which the slot width is narrower at the corners, is used as the complementary part 20 (Fig. 7, not shown). Glass pieces may be tempered by this method whose radius of curvature at the inside of the angle is less than the thickness of the glass.

Title: Phased array system
IPC: G01S13/68
Filed: 1972-09-21
Abstract: A phased array antenna utilizing a parasitic reflector in which the area of the array of radiating elements is smaller than the area of the reflector. The reflector has a concave surface which, in one embodiment of the invention, is a hyperbola of revolution for collimating the rays of radiation incident thereupon from the array of radiating elements. The surface of the reflector is particularly adapted to permit the generation of a set of phase shift command signals by means of a novel ray tracing program to provide a collimated beam which may be scanned in response to the phase shift imparted through radiation radiated by the radiating elements. A narrow beam of radiation is obtained by virtue of the relatively large sized reflector even though the dimensions of the array of radiating elements are relatively small.
