Title: Reactive distillation alkylation process including in situ catalyst regeneration
IPC: B01D3/00
Filed: 2004-08-19
Abstract: A unified process which couples a unique in situ catalyst regeneration process with a continuous reactive distillation under pressure for the alkylation of light aromatic hydrocarbons such as benzene with C<SUB>2</SUB>-C<SUB>30 </SUB>olefins using a solid acid alkylation catalyst supported in the reflux zone of a distillation column. Periodic regeneration of the catalyst is carried out with a countercurrent injection of a C<SUB>4</SUB>-C<SUB>16 </SUB>paraffin below the benzene rectification zone at the top of the column, but above the catalyst zone while the aromatic hydrocarbon reaction feedstock is injected continuously at a point above a rectification zone at the base of the column where the aromatic compound is separated from the paraffin and by-products washed from the catalyst. The use of the C<SUB>4</SUB>-C<SUB>16 </SUB>paraffin with the aromatic at a mole fraction in the range of 40 to 90% enables a regeneration temperature of about 175-250° C. to be achieved and maintained by adjusting the column pressure and aromatic reflux rate. Significantly lower pressures, on the order of 125 to 370 psig, are required to achieve regeneration temperature than would be otherwise required with the use only of the aromatic hydrocarbon to dilute and wash the by-products from the catalyst surfaces.

Title: Catalyzed decomposing structural payload foam
Filed: 2007-02-07
Abstract: A high energy, e.g., ultraviolet (UV), catalyzed decomposing foam encapsulating a payload to be boosted in space provides an ultra-light weight, adaptable means to facilitate survival of much lighter, smaller satellites and space hardware under boost environment. The decomposable foam is to contain multiple satellites within a booster payload in lieu of the traditionally heavy and complex structural framework. The catalyzed decomposing foam significantly lowers the weight and structure of all space hardware. This packaging system is especially beneficial where several or even hundreds of satellites are required for a constellation system, thereby significantly benefiting all technologies applied in space, ranging from the telecommunication industry to DOD applications. In addition to weight and cost savings, advantages of this foam are many in that it is adaptable to any payload shape as it may be injected, sprayed, formed, molded, easily cut or manufactured to support any geometry required.

IPC: F02M61/18
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To allow promotion of atomization of the injected fuel and reduction of processing time in a fuel injection valve of an internal combustion engine. SOLUTION: This fuel injection valve is provided with a needle 4 having an annular seat portion 4b that in tight contact with a valve seat 3a1 at a leading end 411. In this case, a leading end surface 4c of the needle 4 is formed into a gentle conical surface at a tilt angle ranging from 175 deg. to 179 deg. such that energy of the fuel flow can be effectively consumed during opening of the valve for collision of the fuel flows in a space S downstream of the valve portion. As a result, atomization of the injected fuel can be promoted. Furthermore, fluctuation of the rotating axis of the needle at the leading end portion 411 is prevented during grinding work such that a peripheral surface 4a and the leading end surface 4c of the leading end 411 can be subjected to the grinding work together, thus reducing the machining time.

Title: Electromagnetic ultrasonic wave measuring instrument
Inventor: KADOWAKI TAKASHI
IPC: G01B17/02
Filed: 1988-04-25
Abstract: PURPOSE:To decide whether or not the welding of a nugget part is acceptable automatically by detecting a lateral ultrasonic wave which reacts with only the nugget part and a sound wave which is transmitted through the nugget part, and decide whether or not a spot weld zone is acceptable. CONSTITUTION:When the lateral ultrasonic wave is applied to a steel late 2 from a transmitting probe 4, the ultrasonic wave is propagated in the steel plate 2 and when the nugget 1 is formed, the ultrasonic wave is propagated to the steel plate 3 through the nugget 1 and received by a receiving probe 5. Then the output of the probe 5 is supplied to a sound wave detecting circuit 6 and its maximum value is held at the peak by a peak holding circuit 7. Then a circuit 8 finds the width (diameter) (a) and area S' of the nugget from a specific expression based upon the output detection time (t) of the circuit 7, the moving speed V of the material to be inspected, and the diameter (d) of an ultrasonic wave source. A storage circuit 9, on the other hand, finds the area S of the nugget from the output of the circuit 7. Then a judgement circuit 10 judges whether or not spot welding is normal from such acceptance/rejection condition that smaller area between S and S' is larger than a prescribed value.

Title: Radar image display
Inventor: HASUMI KANEYOSHI
IPC: G01S7/22
Filed: 1981-06-29
Abstract: PURPOSE:To prohibit the display of a track only for the secondary video without use of any special memory by separating the storage system for the memory of the secondary radar video from that from the primary radar video. CONSTITUTION:A primary radar video (PSR) signal which is converted into a binary value such as 4 bits excluding the highest value with an analog/digital converter 2 is compared with a secondary radar video (SSR) signal which is encorded into the highest value of binary 4 bits or the like by means of a comparison/selection circuit 4 and the larger value is held in a buffer memory 5 until the updating of a video memory 7. This updating is accomplished by reading out the contents of the memory 7 in such a manner that they are outputted as intact through a decoder 9 not applied to a track processing circuit 8 when corresponding to the SSR signal while applied to the circuit 8 to control the trailing when corresponding to the PSR signal. This permits the prohibition of track display only for the SSR signal thereby preventing misrecognition in reading the indication of the SSR signal without use of any special memory.
