Patent EP-0317918-A2 (EP)
Inventor: CHEM MICHAEL SHI-KUAN
IPC: C07C7/04
Filed: 1988-11-18
Abstract: The present invention is an improved process for separating alcohols from ethers and/or hydrocarbon raffinate in an etherification process. The excess alcohol reactant which forms azeotrope mixtures with the product ethers and C₄-C₇ raffinate, is removed by passing the liquid azeotrope mixture over a pervaporation membrane which effectively breaks the azeotrope and permeates the alcohol with high flux and high selectivity. In a typical etherification process, one or more pervaporation membrane units can be located ahead of the ether/raffinate distillation step, in conjunction with the distillation step with a liquid side draw, after the distillation step, or a combination of any of the above. The present invention also provides an improved process for separating alcohols from ethers and/or hydrocarbon raffinate in an ether decomposition process for the production of high purity iso-alkene products. In this embodiment, one or more pervaporation membranes are used to recover alcohols from the decomposition product stream.

IPC: C08G61/08
Filed: 1988-12-28
Abstract: This invention pertains to polymerization of a monomer charge containing at least one norbornene-type monomer, an optional halometal activator, a ring opening methathesis catalyst and a cocatalyst. The cocatalyst is selected from alkoxyalkylaluminums, aryloxyalkylaluminums, alkoxyalkylaluminum halides, and aryloxyalkylaluminum halides which are prepared by reacting a cocatalyst component selected from alkylaluminum halides or alkylaluminums with a branched alcohol selected from tertiary alcohols, hindered primary alcohols, hindered secondary alcohols, and mixtures thereof. The use of these branched alcohols results in a longer pot life exceeding about one-half hour, preferably exceeding two hours of the monomer charge. This invention is also directed to the composition which includes at least one monomer, optional activator, and the cocatalyst.

Inventor: SHIBATA KOHICHI
IPC: G06T7/00
Filed: 1988-04-07
Abstract: An apparatus for processing an X-ray image, wherein an image signal newly obtained is allowed to pass through a recursive filter means (2, 8) so as to allow objectionable lag to occur between that image and a plurality of images previously obtained. Two-dimensional smoothing within a single image is carried out when the image signal is processed in a smoothing means (9). The image signal taken from the recursive filter means is mixed with the image signal taken from the smoothing means. The mixing ratio for each picture element is determined by a motion detecting means (11), which compares each picture element of the present image signal with corresponding picture elements of the previous image signals and thereby detects the motion of each picture element. Thus noise reduction by smoothing is greater in the case of an image of an object moving quickly, while the noise reduction resulting from objectionable lag induced by the recursive filter means is greater for an image of an object moving slowly.

Abstract: Brakes (1,2; 3,4) on the wheels (5,6; 7,8) at opposite ends of a common axle are each controlled by a separate skid control unit and a single latch valve (21) common to both units closes at the first skid point to be sensed by a sensor (9,10; 11,12) on either wheel. A control module (13) responsive to signals from at least one of the sensors is operative to operate the latch valve and the skid control unit for the respective wheel. When a skid-signal is detected from a sensor on only one wheel the latch valve closes and the brake on the skidding wheel is released and re-applied when the skid signal terminates. The brake is re-applied in a fast first stage, due to pressure from an associated memory chamber and thereafter in a slower second stage due to the latch valve restricting the increase of braking presssure when it is closed. The rate of increase of brake pressure of the non-skidding wheel is restricted to that of the slow stage from the time that the latch valve is closed due to the other wheel skidding.

Abstract: Package inspection systems are disclosed which are capable of high speed sensing and evaluation of package integrity as packages (18) are continuously conveyed in the manufacturing process. The systems are capable of measuring predetermined parameters of packages, e.g. cigarette packages, comparing the measured parameters with predetermined values, evaluating from the measured parameters the integrity of the packages and determining whether such packages are acceptable or, alternatively, should be rejected. The system can additionally obtain and store data on sensed package parameters for evaluating long-term and short-term manu­facturing trends. In various embodiments of the invention, the system can inspect a single or plural package side(s), employing a single or plural line scan (12) or area array camera(s) and may employ special optics to enable plural package side images to be obtained using a single camera. There is also provided improved conveying systems for package inspection and master part detect systems which can be employed to obviate the need for synchronization between the inspection system and the conveying system.

Abstract: Disclosed is a method of facilitating program to program communication within memory space managed by a given processor. Sender programs communicate with receiver programs via an intermediate communication facility pro­gram acting as a central "post office" for the senders and receivers. Receiver programs identify themselves to the communication facility program by registering their iden­tification and status therewith. Thereafter, any sender programs can send messages or data to any receiver pro­grams which have been defined to the communication facili­ty program. Senders need not be defined to the communica­tion facility program but need only request delivery of data or a message to a targeted receiver.

Abstract: High resolution absorption microscopy, spectroscopy and similar applications are implemented by providing for a measurement tip (21) which is maintained spaced from a sample (10) under investigation sufficiently close so as to equalize thermal levels in the tip (21) and the sample (10); generally within about 1 nm. Energy is applied to the sample (10) being investigated and either a steady state or dynamic junction potential is measured. The close separation can be maintained by techniques employed in scanning tunneling microscopy, atomic force microscopy or capacitance microscopy. In the event the close separation is maintained using scanning tunneling microscopy techniques, then a switching arrangement (30) is provided for connecting a conductive film (11) (either of the sample (10) or supported on a sample (10)) to either a suitable potential or ground and simultaneously connecting the STM tip (21) either in a feedback loop or to a device for measuring the junction potential. The feedback loop, in addition to conventional operational amplifier components, includes a sample and hold element (55) to maintain the input voltage to an operational amplifier (23) in the feedback loop during those times that the measurement tip (21) is connected to the junction potential measurement device, as opposed to being connected in the STM feedback loop. The spectroscopy application uses similar architecture, although the energy source (15) is tunable.

The drive system includes a voltage-increasing section for increasing an output voltage of a power source mounted on the motor vehicle so as to develop a drive voltage for the piezo-type actuator and a voltage-application section for applying to the piezoelectric device of the piezo-type actuator the drive voltage. Also included in the drive system is an abnormality detection section which is arranged so as to an abnormality of the drive voltage developed by the voltage-increasing section. A safety controller is responsive to an abnormality signal from the abnormality detection section for prohibiting the application of the drive voltage to the piezoelectric device thereof and further discharging charges accumulated in the piezoelectric device thereof when the abnormality detection section detects the abnormality of the developed drive voltage. With this arrangement, it is possible to prevent troubles due to the abnormality of the drive voltage to be applied to the piezoelectric device of the piezo-type actuator.
