Abstract: An organopolysiloxane, containing a C1-18, optionally halogenated, hydrocarbon group, is used as the fluid in a viscous coupling, with as additive:
     a) a phosphorus type anti-wear agent (27 formulae are given), e.g. a triaryl phosphate, optionally also with a sulfur or zinc dithiophosphate agent, each in amount of 0.01 - 5 wt %; or   b) a metal deactivator, e.g. benzotriazole or other heterocylic compound or an organic acid, and or a corrosion inhibitor, e.g. a stearate, each in amount of 0.001 to 1 wt %.

Abstract: A metal gasket of the invention is designed to reduce heat transfer between two engine parts. The gasket (D) is formed of at least two plates (D22, D24) having holes (20) to be sealed and bolt holes (21), a sealing device (D22a) formed around the hole to be sealed, and a space forming device (D24a) formed on at least one of the plates to separate the plates apart. Spacers (D27) are formed around the bolt holes so that bolts can be tightened up to a predetermined thickness. When the gasket is tightened, the sealing device (D22a) is compressed to seal around the hole, but the two meal plates (D22, D24) do not closely abut against each other by means of the space forming device (D24a). Accordingly, heat is partly radiated through the gasket, and heat transmission between the engine parts is reduced.

Abstract: This electrodeless high intensity discharge lamp comprises a light-transmissive arc tube having spaced wall portions of dielectric material and a first gaseous fill within the arc tube. An excitation coil about the arc tube is energizable with RF current effective to develop a toroidal arc discharge in the first gaseous fill upon a dielectric breakdown of the fill. A starting container is joined to the arc tube and has an end wall constituted by one of said arc-tube wall portions. a second gaseous fill within the starting container has a dielectric strength lower than that of the first gaseous fill. For initiating said toroidal arc discharge, we provide means for producing a dielectric breakdown of the gaseous fill within the starting container that develops into an electric discharge that changes the potential at said end wall in such a manner as to cause a dielectric breakdown of said first gaseous fill.

Title: Interdigitation-fusion liposomes and gels.
Inventor: BONI LAWRENCE T
IPC: B01J13/02
Filed: 1991-01-11
Abstract: This invention relates to interdigitation-fusion (IF) liposomes and gels. These liposomes and gels capture high solute to lipid ratios, including bioactive agent. This invention also relates to the discovery that the fusion of liposomes to produce IF gel and liposomes according to the present invention is size dependent. The present invention also relates to a method for producing IF liposomes and gels. In the method of the present invention, sized liposomes formed by sonication, extrusion or alternative processes are fused in the presence of ethanol or other suitable inducer. This process results in a composition of the present invention in gel form. To produce liposomes, the gels are exposed to a temperature usually but not necessarily above the transition temperature (Tm) of the lipid used. The temperature required by the methods of the invention is that temperature which induces a change in the material properties of the mixture. The inducer may also be removed. The result is a composition comprising liposomes containing high solute to lipid ratios. The IF liposomes and gels of the present invention may be used in combination with numerous solutes, especially including bioactive agents.

Abstract: A method for cleaning and protecting a diesel cooling system from corrosion and the effects of the corrosive by-products wherein a filter is used to feed a dissolvable pellet comprising dissolvable cleaning agents and corrosion inhibiting agents into the cooling system. The cleaner consists of chelating agents, surfactants, and anti-foaming agents. The filter is removably inserted in the cooling system, and the cleaners and inhibitors dissolve in the coolant to clean and protectively coat the cooling system while the engine is operating. The removed impurities are captured by the filter and the filter is replaced within a few weeks with a standard filter containing inhibiting agents. The method thus does not require draining the cooling system to clean the cooling system.

Abstract: ClO2 is produced efficiently by the redn. of NaClO3 in an aq. medium. The reaction is carried out at the b.pt. under reduced pressure. Pref. HClO3 and HCl react with consumption of Cl- and formation of HClO, which is reduced to Cl- by MeOH. If HClO is produced more quickly than it is consumed, it reacts with HCl to form Cl2. This hampers prodn. of ClO2 and also contaminates the prod.. Lower acidity with higher ClO3- concn. controls the rate of HClO formation. The concn. of acid (H2SO4) is below 7 N (above 5 N) and that of ClO3- is 2-6 (2.5-4) M. Partic. concns. used are mutually dependent. NaHSO4.Na2SO4 is obtd. as a by-prod.. MeOH consumption is approx. 0.2 (0.13-0.16) tons per ton of ClO2 produced; the latter is admixed with steam. The efficiency of ClO2 prodn. is at least 90% (exceeds 95%).
