Abstract: ABSTRACT OF THE DISCLOSURE           PROCESS FOR PREPARING POLYKETONES           A process for preparing interpolymers of an olefin(s) and carbon monoxide (polyketones) is provided.  The process employs a palladium catalyst prepared by reacting together a palladium source, a bidentate amine, phosphine, arsine or stibine and a source of a borate anion. The catalyst effects fast polymerisation of the olefin(s) and carbon monoxide in, e.g. methanol or ethoxyethanol solvent.  By using the catalyst a lower catalyst deactivation on recycle is observed relative to previously described systems.

Title: Vortex generator-sensor
Inventor: LEW HYOK S
IPC: G01F1/708
Filed: 1988-12-16
Granted: 1993-04-27
Abstract: VORTEX GENERATOR-SENSOR Abstract of the Disclosure A vortex flowmeter comprises a vortex generator-sensor including an elongated cylindrical member  (1) disposed across a cross section of the flow passage  (4) wherein one extremity (2) of the elongated cylindrical member  (1) is secured to the wall  (3) of the flow passage  (4), while the other extremity (7) is connected to a force receiving member (6) extending from a transducer assembly  (5) by mechanical coupling  (8).  The vortices shed from the two opposite lateral sides of the elongated cylin-drical member  (1) in an alternating mode generate alternating lateral fluid dynamic force on the elongated cylindrica member (1), which in turn generates alternating electrical signal from the transducer.  The velocity of the fluid flow is determined from the frequency of the alternating electrical signal and the mass flow rate of the fluid is determined from a combination of the frequency and the amplitude of the alternating electrical signal.

Title: Supercharging pressure control method for internal combustion engines
Inventor: INOUE KAZUO
IPC: F02B37/18
Filed: 1988-12-28
Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE     A method of controlling supercharging pressure in an internal combustion engine having a supercharger having an increase rate-varying device for varying an increase rate of the supercharging pressure.  The supercharging pressure is controlled to a desired value in response to a difference between an actual value of the supercharging pressure and the desired value.  The increase rate-varying device is held in a position for obtaining the maximum increase rate of the supercharging pressure while the actual value of the supercharging pressure is below a predetermined value which is lower than the above desired value. The predetermined value is set to a lower value as the increase rate of the supercharging pressure is larger, or when a transmission of the engine is in a lower speed position than when the transmission is in a higher speed position.  Also, the predetermined value of the supercharging pressure is set to a lower value as an actual intake air temperature is lower.

Abstract: ABSTRACT       Disclosed is a boom mount type tree processing head that incorporates a number of improvements, one of which includes the ability of processing a number of trees at one time by using an accumulator type grapple arrangement.  The accumulator grapple disclosed is two sets of grapples spaced apart from one another longitudinally along the processor with the arms of one grapple set being longer than that of the other.  The grapple with the shorter arms also serves to press the tree against an improved endless conveyor type drive that propels the trees endwise for processing.  The endless drive includes two spaced apart endless chains located respectively on opposite sides of the feed path and interconnected by a plurality of somewhat resiliently flexible shoes.  The processing head is hydraulically operated and included is an improved mounting for the hydraulic lines that includes a rotory coupling mounted on the processing head and having a rotor with hydraulic lines connected thereto that turns in response to pivoting of the processing head on the end of the boom.  The processing head is suspended from the boom by a joint that includes at least one device to damp oscillatory movement of the processing head.  The damping device is a rotory actuated hydraulic device with motion being resisted through shifting liquid from one chamber to another and throttling the flow.

Date Jan. 3, 1986.The invention is directed to a composite-type paper making wire or screen, comprising an upper or forming fabric and a lower or wear fabric including at least three sets of longitudinal threads and at least two sets of cross threads. Due to the imperfect nature of the paper-facing surface which results in all kinds of markings in the paper, paper making screens of this type are unsuited for the manufacture of fine papers. To eliminate this drawback, the screen is formed in such a way that at least half of all outwardly disposed longitudinal knuckles of the upper fabric (paper-facing side) of the screen are formed of two sets of longitudinal threads and that the first set of longitudinal threads is woven with the first set of cross threads, the third set of longitudinal threads is woven with the second set of cross threads, and at least portions of the second set of longitudinal threads are woven with both sets of cross threads.
