Abstract: Described is a ozonizer with a first metal electrode and a second metal electrode with a discharge gap between them, the first electrode being covered with a dielectric. At least the first electrode is designed as an aluminium or aluminium-alloy coating on a glass substrate. The dielectric consists of a thermally sprayed ceramic film, preferably made of .alpha.-aluminium oxide, titanium oxide or hafnium oxide. Also described is a method of manufacturing the ozonizer, the method calling for the ceramic film acting as the dielectric on the first electrode to be applied by thermal spraying. The two electrodes are preferably also produced by thermal spraying. The ozonizer has a particularly high yield, is corrosion-resistant and can be manufactured simply and inexpensively.

Abstract: An overload protection and control circuit and methods for electrocoat painting systems is disclosed. A resistive shunt is utilized to generate a voltage proportional to the level of current flow to electrodes in the electrocoat painting system. After amplification, the generated voltage is compared with a reference voltage. If the current exceeds a predetermined level, indicative of an overcurrent condition, a comparator causes a control circuit to disable current flow. A timer is provided to delay re-enabling of current flow for a predetermined delay interval. The control circuit may receive inputs from a control PLC or computer. The control PLC or computer may receive inputs from sensors such as a pH sensor or a membrane monitor. The control PLC or computer may selectively control the control circuit to various electrodes so as to more appropriately operate the electrocoat painting system.

Abstract: A crystalline ternary alloy of nickel, cobalt and boron has been found to have multiple uses. The alloy has a composition of, by weight, 50-75% nickel, 25-50% cobalt, and 1-5% boron. Structurally, the alloy consists of 50-75% Ni.sub.2 B crystals and 25-50% Co.sub.2 B crystals contained in a matrix of nickel cobalt. The alloy has been found to have high catalytic capabilities and decreases the energy requirements for the electrolytic production of gasses such as hydrogen and halogens. The alloy also has good magnetic properties indicating that it can be used as a coating for a magnetic data storage media, or a thin film for a read/write head which writes to and reads from the magnetic storage media. The alloy has a magnetorestrictive coefficient that is substantially zero or negative, a magnetic saturation where 4piM.sub.s is greater than 20 KGauss, a coercivity of approximately 1.24, an anisotropy of 3.74, and a magnetic permiability in excess of 1000.

Abstract: Processes for forming stable electrodes for use in electrochromic devices are disclosed including a stable electrode, a second electrode, and an ion-conducting layer therebetween, the processes include placing the stable electrode in an ion-conducting solution, placing a source of ions capable of chemically reducing the stable electrode in the ion-conducting solution, causing the ions and associated electrons to migrate to and chemically reduce the stable electrode, and forming an ion-conducting layer on the stable electrode from the ion-conducting solution.

Abstract: A high throw power electrodeposition system with improved rupture voltage is disclosed. The electrodepositable coating includes an active hydrogen-containing ionic resin and a gamma hydroxy urethane curing agent, such as a curing agent having the structural feature: ##STR1## The gamma hydroxy urethane curing agent can be prepared by reacting a polyisocyanate with a 1,3-polyol, and in particular with 2,2,4-trimethylpentane-1,3-diol. The composition can also include a curing agent having an alkyl urethane structural feature which can be the reaction product of a polyisocyanate and a blocking agent which is a fatty alcohol. A method for coating a conductive substrate with the above-described composition is also disclosed. The method includes passing an electric current between the conductive substrate serving as a first anode and a second anode to deposit the composition and the conductive substrate.
