Abstract: 1,169,421. Unbalance computers. LOSENHAUSENWERK DUSSELDORFER MASCHINENBAU A.G. 6 Jan., 1967 [16 Feb., 1966], No. 981/67. Heading G4G. [Also in in Division G1] In a rotary balancing machine, the test body is rotated and the unbalance signals S 1 , S 2  generated at two bearing planes are connected into compensating masses A 1 , A 2  at two predetermined compensating planes by an electrical network which solves the equations: where a<SP>1</SP> and c<SP>1</SP> are the distances from a common reference plane to the compensating planes, d<SP>1</SP> is the distance from one of the bearing planes to the reference plane and l is the distance between the bearing planes, the position of the reference plane being chosen so that the quantities a<SP>1</SP> c<SP>1</SP> and d<SP>1</SP> are all of comparable magnitude. In Fig. 1, the unbalance signals S 2  and S 1  are applied at inputs 1 and 2 respectively. Identical resistors 4, 5 form the sum (S 1  + S 2 ) on line 6 and resistors 7 and 9 multiply (S 1  + S 2 ) by d<SP>1</SP> and S 1  by l respectively to form at their junction the expression d<SP>1</SP>(S 1  + S 2 ) + lS 1  which is in turn added through resistors 12 and 13 to the terms a<SP>1</SP>(S 1 +S 2 ) and c<SP>1</SP>(S 1  + S 2 ) respectively tapped off from line 6 by potentiometers 10 and 11.

Title: High impact strength fiber resin matrix composites
Inventor: HIRSCHBUEHLER KEVIN RICHARD
IPC: B32B5/28
Filed: 1992-04-16
Abstract: Improved fiber resin matrix prepreg fabrics are disclosed which are comprised of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The discrete second layer is provided with a support comprising a gauze-like, lightweight fibrous mat or carrier of light-weight fibers that preserves the second "interleaf" layer during cure. Cured composites having the continuous interleaf layer intact exhibit high impact strength and resistance to impact damage. In addition, high-performance fiber resin matrix composites are disclosed which are comprised of a first layer comprising reinforcing filaments coated with a thermosetting resin composition and a discrete second layer of a thermoplastic resin. When the composite layers are matched to provide certain minimum strength and elongation properties, composites of unusually high impact strength and resistance to impact damage are achieved which retain their high performance properties over a range of temperatures and environmental exposures.

Filed: 1991-01-07
Abstract: PURPOSE:To reduce material charging time and ease load imposed on an evacuating means by installing an evacuating device in a raw material charging chamber and connecting a vacuum chamber with said raw material charging chamber by way of valve. CONSTITUTION:When a raw material is charged into a dissolution chamber 1, a vacuum valve 3 is closed and a vacuum state is kept in the dissolution chamber 1 by an evacuating device 8 while an ON/OFF valve 10 is closed simultaneously, evacuating a vacuum chamber 11 by means of or evacurating device 9. Then, a vacuum valve 5 is opened and after the raw material is brought into a raw material charging chamber, the vacuum valve 5 is closed, whereas the ON/OFF valve 10 is opened so that the pressure in the both chambers 4 and 11 may be equalized. After the pressure is equalized, ON/OFF valve 10 is closed, an ON/OFF valve 7 is opened so that the raw material chamber 4 may be evacuated by means of the evacuating device 9. The vacuum valve 3 is opened so that the raw material in the raw material charging chamber 4 may be charged into a furnace 2 of the dissolution chamber 1. On the other hand, the vacuum chamber 11 is evacuated by means of the evacuating device 9 and the vacuum valve 3 is closed once again, whereas the vacuum valve 5 is opened, thereby bringing the subsequent raw material into the raw chamber charging chamber 4. It is, therefore, possible to shorten the time required for evacuation.

IPC: G06F13/00
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To artificially change the priority of transmission at any arbitrary time point when transmitting data to plural computer systems under the control of a data transmission program. SOLUTION: A transmission data priority control means 4 receives change information from a priority change means 3 and sets it to a control table as change information. When the change information is not inputted from the priority change means 3, on the other hand, the transmission data priority control means 4 retrieves data in the waiting state of transmission from a control table and generates change information while dynamically changing the priority so as to automatically equally transmit the data to the computer system of a party. This change information is set to the priority column of object transmission data in the control table.  Namely, the transmission data priority control means 4 compares the number of pieces of data, dynamically changes the priority so as to equally transmit data to the plural computers of parties and sets them to the priority column of the transmission object data in the control table as the change information.
