Title: Radiation measuring apparatus and method
IPC: G01T1/17
Filed: 1985-08-21
Abstract: This invention relates to apparatus for and a method of measuring radiation field strength which uses a pulse enabled detector (Geiger-Mueller tube) and is based on the equation R = K/t, where R is the radiation field strength, t is the time till first strike, and K is a proportionality constant for the given apparatus. The apparatus and method substantially eliminate measurement errors due to circuit propagation time delays and slow drift conditions, Geiger-Mueller tube turn-on time and response curve variations, and the need to manually calibrate the measurement apparatus in high radiation fields to compensate for time errors. When mean times are short the calculation of the rate is an estimation of the mean time to strike, which in turn is equivalent to estimating the mean (1/nR) of an exponential probility distribution function (PDF) nRe<-nRt>. This function has the property that the expected value for the arithmetic mean of any right hand segment of the curve is always the same provided that the time axis is adjusted so that the starting point of the selected segment is zero. The curve is trimmed dynamically each time a new rate is calculated. 
<??>An individual count of strike events is kept (28) for N separate but consecutive time units, and the counts for the later occurring events are lumped together as the Main Event. After the data collection period ends, a total accumulated time and accumulated count are constructed. This construction begins by examining the Main Event data. If enough data is present to derive a statistically acceptable estimate (250-500 events) the data in the first N time units is ignored. If more data is desirable, the data is factored in, one time unit at a time starting backward from the event count corresponding to the time unit with the longest time. The total time is now adjusted so that the starting time corresponding to the selected portion of the PDF is zero. This adjustment also includes a further adjustment which compensates for the digital approximation of the continuous variable time, corrects most of the error caused by the discrete clock frequency, and helps to adjust for additional curvature errors which are most pronounced when the mean time to strike is close to the clock time. An estimate for rate is made by dividing the total adjusted number of counts by the total adjustment accumulated time and multiplying by a scale factor.

Abstract: A process for fabricating self-aligned regions of metal 
silicide on bipolar integrated circuits having self-aligned 
polycrystalline silicon emitters and base contacts includes 
the steps of depositing a layer of polycrystalline silicon 
across the surface of the structure, patterning the polycrys­
talline silicon to define the emitters and base contacts as well 
as resistors and diodes, heating the structure to transfer de­
sired conductivity dopants from the polycrystalline silicon 
into the underlying structure, forming a protective layer over 
those regions of the structure where metal silicide is not 
desired, depositing a layer of refractory metal across the 
entire structure, and reacting the refractory metal with the 
underlying silicon to form metal silicide.

Title: Method and apparatus for reducing sulphur dioxide content in flue gases
IPC: F23J3/00
Filed: 1987-07-10
Abstract: A method and apparatus are employed to reduce the sulfur dioxide produced by the combustion of a sulfur-containing fuel in a combustion chamber. Part of the combustion air is introduced into the combustion chamber with and closely adjacent the fuel. Another part of the combustion air is introduced into the combustion chamber above and downstream of the fuel and relatively remote therefrom under conditions which buffer the flame front and reduce peak flame temperatures therein. Finely divided limestone particles or the like are aspirated into the combustion chamber by the air introduced above the fuel and distributed thereby throughout the gases flowing downstream through the combustion chamber wherein the limestone particles are calcined to lime particles which react with the sulfur dioxide in the combustion reaction gases to produce calcium sulfate. There is no premixing of the particles and the aspirating air before they enter the combustion chamber. Various parameters are controlled to produce the desired results. <IMAGE>

Title: Hydraulic impact tool
IPC: B25D9/18
Filed: 1989-07-25
Abstract: An impact tool including a cylinder (1), a piston (3) slidably 
mounted in the cylinder and a valve (10) for selectively opening 
and closing oil feed channels to move the piston (3) up and 
down. A cylindrical member (21) is slidably mounted on the 
piston around its large-diameter portion or thereunder. Its 
bottom end defines the top end of a lower chamber (7) formed in 
the cylinder. The cylindrical (21) member is adapted to descend 
together with the piston (3). But when the piston strikes the 
object (2) and rebounds upwardly, the cylindrical member (21) keeps 
descending away from the piston (3) owing to the inertia force. 
Thus the volume of the lower chamber (7) is kept from increasing 
excessively after the piston has struck the object. This 
will prevent cavitation in the lower chamber (7). When 
thereafter the lower chamber communicates with the oil feed 
port (12) and pressure oil is fed thereinto, the cylindrical 
member (21) will be pushed up toward the large-diameter portion 
under oil pressure in the lower chamber.

vitamin in the digestible fat of the first fraction is 
at least twice as high as in the polyol fatty acid 
polyesters of the second fraction, and subjecting the 
combined fractions to such mild processing conditions 
that the final product comprises the fat of the first 
and the fat of the second fraction in the form of two 
distinct fat phases.
