Title: Liquid lubricating composition and process for preparing thereof
Inventor: WU MARGARET MAY-SOM
IPC: C10M105/04
Filed: 1989-05-22
Abstract: Novel lubricant compositions comprising polyalpha-olefins are disclosed having high viscosity indices with low pour point. The compositions are characterized by a uniform molecular structure with low branch ratios. The invention describes a liquid lubricant composition comprising C30-C1300 hydrocarbons, said composition having a branch ratio of less than 0.19, weight average molecular weight between 300 and 45,000, number average molecular weight between 300 and 18,000, molecular weight distribution between 1 and 5 and pour point below -15  DEG C. 1-decene trimer comprising 9-methyl, 11-octylheneicosane and 11-octyldocosane is disclosed. The lubricant compositions are produced by contacting said alpha olefin with a supported solid reduced Group VIB (e.g., chromium) catalyst under oligomerization conditions at a temperature of about 90 to 250  DEG C to produce liquid lubricant hydrocarbon. The hydrogenated lubricant range hydrocarbon product has viscosity index of about 130 to 280 and a viscosity up to about 750 mm<2>/s(cs). The process is particularly useful where the starting alpha olefin consists essentially of olefinic hydrocarbon having 8 to 14 carbon atoms or mixtures thereof; wherein the process conditions include reaction temperature of about 100 to 180  DEG C; and wherein the support catalyst includes porous inert silica.

Title: A method for determining the type of ionizing radiation and a connection for implementing this method
Inventor: Krist Pavel
IPC: H01L29/868
Filed: 2017-10-12
Abstract: To determine the type of ionizing radiation using a semiconductor PIN diode connected in the reverse direction, a PIN with a low or zero negative bias of zero to unit volts is used. At its output, the charge is proportional to the energy transmitted to it by the incident ionizing radiation. This charge is then amplified and converted to a voltage pulse whose surface corresponds to the energy transmitted by the ionizing radiation of the diode. The signal is evaluated using shape discrimination to determine the type of ionizing radiation. The positive ion response has a larger amplitude than the response from the photon at the same pulse width, i.e., at the same energy transmitted. The semiconductor PIN diode connected in the reverse direction is outputted to a hub amplifier that is connected to a computer via a filter and an A/D converter.
