Title: The method for separating air
Inventor: TOMISAGA YASUSHI
IPC: F25J3/04
Filed: 1983-06-03
Granted: 1988-02-22
Abstract: A blower is used to extract argon-rich gas from the top of the crude argon column in order to provide the necessary reduced pressure of 0.8-1.0 atm. within the column.  The blower replaces the oxygen compressor conventionally used in the oxygen product line to decompress the crude argon column by suction.  An additional modification is that liquid oxygen is withdrawn from the crude argon column via a descending line at a level below the liq. level thereof.  The liquid oxygen is thereby pressurised under its own gravity to the required pressure of 1.0-1.2 atm.

Inventor: HEIJNEMANS WERNER A L
IPC: H04N5/926

Granted: 1995-09-22
Abstract: In a method of recording video information in a record carrier (10), each picture (1) of NxM picture elements being divided into subpictures (2) of nxm picture elements, the video information of each subpicture is encoded in accordance with a transform coding (Ti) and recorded on the record carrier. Moreover, corresponding subpictures 11.1, 11.2, Fig. 4a) of two pictures (B1, B2) are compared with each other. To both subpictures a motion code (mci) is assigned, which motion codes are the same if the subpictures do not differ substantially from one another, but which are not the same (mc1, mc2, Fig.4c) if the subpictures (16.2, 16.3) differ substantially from each other. The motion is recorded on the record carrier (10) together with the coded information of the subpicture. Moreover, different transform codings (T1, T2, Fig.4a) may be applied to the subpictures. A higher-order transform coding yields a more accurate information of the subpicture which is encoded (Fig. 3). The associated transform code (Ti) is also recorded on the record carrier (10). Further, a method of reproducing video information from the record carrier (10) is described (Figs. 5, 6) and apparatuses for carrying out the two methods are described (Figs. 7 to 11).

Abstract: The jig including a pneumatic cylinder,  a  spring  wire  and bending units automates the bending work  of  the  component  legs whose shapes are so different  that  the  bending  work  has  benn manually carried out. When a circuit board (13) set on the top  of the jig body (1) presses a limit switch (3), the top support plate (2) is closed down over the board  with  a  handle  (17)  so  that support pieces (16) provided on the inner face of  the  plate  (2) pressingly hold the tops of components mounted on the board  (13). A switch is then pushed to move backward  the  shaft  (5)  of  the pneumatic cylinder (4) for the spring wire (7) clamped in a drawer (6) fixed to the tip of the shaft to be drawn  through  a  support holder (8) to draw the lower end of the bending piece (11) of each bending unit. Then, the spring wire being drawn bends the legs  of the components on the board by means of a bending member (12). The jig improves the productivity of the bending work.

Abstract: (A) 5-90 wt.pts. of polyester resin; (B) 5-90 wt.pts. of the copolymer resin to be prepared by compolymerization of styrenic monomer and vinyl cyan based monomer; (C) 1-30 wt.pts. of aromatic polycarbonate resin; (D) 1-20 wt.pts. of olefin copolymer comprising α-olefin and α,β-unsatd. acid glycidyl ester; and (E) 1-200 wt.pts. of glass fiber. Pref. the α,β-unsatd. acid glycidyl ester is the cpd. of formula (I), where R1 is H or C1-3 alkyl. The obtd. resin compsn. is good surface, moldability, and improved impact resistance.
