Title: Method for the manufacture of gold-coloured coatings
IPC: G04B37/22
Filed: 1978-12-15
Abstract: A method of producing gold-color coatings on substrates by evaporating a coating material comprising a metallic titanium or zirconium in a housing which has walls which define an evaporation space, comprises, maintaining a vacuum atmosphere containing N2 and argon in the space. The method is carried out using an anode connected to a power source to produce a low voltage arc discharge in the vicinity of the coating material which is arranged within the evaporation space and also maintaining a low voltage arc between the anode and the substrates. A potential difference between the anode and the substrates of a range of between 5 v and 100 v are maintained during the process and, in addition, the electrical potential of the substrates is maintained between 0 and 150 volts lower than the potential of the housing walls which define the evaporation space. The substrate to be coated is coated at a rate of from between 1 to 15 nanometers per second. The N2 and argon atmosphere is maintained so that a partial pressure of the N2-containing component ranges between 2x10-4 and 10-2 millbar. The potential difference between the anode and the substrates is reduced in the course of the process to release the sputtering threshold of the substrate and the housing wall. The partial pressure of the N2-containing components continuously increase in the course of the process.

Title: Detecting fault in insulated electric cable
IPC: G01R31/08
Filed: 1979-10-22
Abstract: Apparatus and a method for detecting a fault in an insulated electric cable with a spiral electrical conductor are disclosed. The cable (8) is passed through a pair of spaced- apart metal tubes (4, 5), each of which is connected to a respective side (2 or 3) of a balanced output of an oscillator (1). Between the tubes there is a pair of spaced-apart matched coils (6, 7) through which the cable passes, the coils sensing magnetic flux due to alternating current (I) flowing along the conductor (11) of the cable due to capacitive coupling via the tubes. The output of each coil is applied to an amplifier (12 or 13), a filter (14 or 15) and a signal level detector (16 or 17), each detector producing a DC output signal level. The levels produced are compared in a comparator (18) and if the latter detects a difference between the signal levels it compares greater than a certain amount (indicating a discontinuity in the conductor of the cable or a variation in pitch in the conductor of the cable greater than a certain amount, an audible alarm (21) is activated and a marker (22) marks the cable. The levels produced by the detectors are monitored by a level meter (19) and a deviation meter (20) monitors the difference between the signal levels compared by the comparator. <IMAGE>

Title: Fluid-Transfer Roller
IPC: B41F31/26
Filed: 1980-02-26
Abstract: A cylindrical roller body (10) has a surface texture incorporating a random pattern of interconnected channels or "cracks" (18) and lands (20) and may be mounted for rotation contiguous with a second roller (22) having a fluid supply (30), for transferring fluid therebetween, thereby forming a uniform fluid layer (32), available for deposit.
