Patent EP-0303220-A2 (EP)
Inventor: SEKI KIWAO
IPC: F04B9/04
Filed: 1988-08-08
Abstract: A low pulsation displacement pump has a pair of plungers (4, 5) and motor driven-cams (2, 3) or feed screws (45, 46) for reciprocating the plungers. In order to cause the pump to stably discharge a liquid so that variation in discharge due to machining errors of the plungers or the feed screws is eliminated, the pump discharge pressure is measured at each of a plurality of predetermined operative positions of the plungers before delivery of the pump from a manufacturing plant, and machining errors are obtained in accordance with the thus-measured discharge pressure. Then, the speed correction factor for the motor is calculated for each of the plurality of predetermined positions of the plungers in accordance with the thus-obtained errors to store the results of the calculation in a memory (20). When the pump is used, the motor is operated while the speed of the motor is compensated for at each of the plurality of predetermined positions of the plungers in accordance with the speed correction factor stored in the memory, whereby the rate of discharge of pump can be kept substantially constant by preventing speed variation of the plungers due to machining error of the cams.

Abstract: A method of making an electrically insulated terminal (12) in an injection nozzle (10). After the heating element (44) is wound in a spiral channel on the outer surface (36) of the main body portion (14) of the nozzle the rear end (104) projects radially out an opening (80) in the collar portion (16). The casing (102) is stripped from the heating element to expose the resistance wire (112) adjacent the rear end. A steel plug (78) having a central bore (76) therethrough is slipped over the projecting rear end and welded into place in the opening. A steel terminal body (82) is made with a central bore (106) and a threaded front portion (84) to receive an external power lead (118). The casing (102) of the portion of the heating element (104) projecting from the plug and a rear portion (88) of the terminal body (82) are coated with insulating material (92). A protective cap (94) is securely swaged over the coating on the rear portion. The assembled cap and body are slipped over the rear end of the heating element and welded to the matching front face (100) of the plug (78). The exposed resistance wire (112) is welded to the terminal body (82). This structurally secures the terminal body against torque from connecting and disconnecting the external lead and electrically insulates it from the rest of the nozzle, while electrically connecting it to the resistance wire. In an alternate embodiment, the connections are made while integrally brazing the nozzle in a vacuum furnace.

Abstract: To test growth factor production, healing bone marrow-conditioned medium was prepared with tissue separated from rat tibias during the osteogenic phase and assayed for enhancement of mitogenic activity in culture of osteogenic rat osteosarcoma cells (ROS 17/2). Partial purification of healing bone marrow-conditioned medium-derived growth factor(s) consisted of gel filtration on Sephadex G-25, boiling, chromatography on heparin-Sepharose, and gel filtration on Sephadex G-75. Mitogenic activity eluted in the void volume of the Sephadex G-25 column (mol wt > 5,000). Potent activity resolved from heparin-Sepharose with PBS, and on filtration by Sephadex G-75 this activity recovered in 3 peaks with mol wt estimates of 35,000, 19,000 and less than 10,000. The partially purified factor also showed considerable stimulatory effect on DNA synthesis in osteoblastic fetal rat calvarial cells and on  in vitro  elongation of fetal long bone; it had only a small effect on nonosteoblastic ROS and fetal rat calvarial cells. These data indicate that healing bone marrow produces growth factor activity with a preferential effect on osteogenic cells.
