Title: Oligosaccharide oxazolines, oligosaccharide conjugates and methods of preparation thereof
Inventor: COLON MARCELO
IPC: C07H9/06
Filed: 1991-05-24
Granted: 2002-01-01
Abstract: This invention relates to a method of producing peracetyloxazolines from peracetyl saccharides. The method involves reacting the starting material, a peracetyl saccharide, with a reagent combination, to directly produce the peracetyl oxazoline. This method maybe used for the activation of oligosaccharides, wherein an oligosaccharide containing a reducing GIcNAc terminus is activated by the formation of an oxazoline at the terminal GIcNAc, and then coupled with a bifunctional spacer to provide an oli-gosaccharide-spacer conjugate. The activated oligosaccharide-spacer conjugate is then coupled to a protein, such as granulocyte colony stimulating factor or .gamma.-interferon, providing a neoglycoprotein conjugate. The invention provides a method for forming neoglycoprotein conjugates which may improve biological and physiochemical properties of the protein. For example, serum life-time or efficiency of drug delivery of the peptide to a target organ or cell may be improved.

Title: Log splitter
Inventor: GREEN ROBERT H
IPC: B27L7/00
Filed: 1994-12-21
Granted: 1999-02-23
Abstract: An improved hydraulic log splitter which includes a hydraulic reservoir formed integrally with a frame of the log splitter.  Hydraulic fluid from the reservoir is supplied by a pump to a control valve. A fluid passage is open through the control valve to a hydraulic intensifier which includes a cylinder and a piston extendable from the cylinder.  The piston pushes a log against  a stationary splitting wedge.  The piston is urged toward a retracted position by a return spring internal to the cylinder.  When the control valve is in other than an "extend" position, hydraulic fluid supplied to the control valve is allowed to flow into a return conduit back to the reservoir.  In this condition, the pressure the hydraulic fluid develops insufficient force to overcome the force exerted by the return spring, and the ram remains retracted.  When the control valve is placed in the "extend" position, fluid that flows to the return conduit is blocked and the pressure in the hydraulic intensifier rises to overcome the force of the spring and advance the ram.  A log placed on the splitter is thus driven by the piston to be split by the wedge.  The wedge is designed to force the log against guide rails during splitting.

Abstract: An optical probe (23) receives a laser beam from a laser (21) and an input signal (I) with an input signal intensity and do input amplitude to produce a permeating beam having a beam intensity which is varied in response to the input signal intensity. A receiving device (27) receives an electric signal having a converted amplitude from a photoelectric converter (25) which converts the permeating beam into the electric signal. Supplied with the electric signal, a feedback control device (35) produces a feedback control signal. A laser control device (37) controls the laser in response to the feedback control signal so that the converted amplitude is approximately equal to a constant amplitude regardless of the input amplitude. The laser control device may control the laser so that the beam intensity is approximately equal to a constant beam intensity regardless of the input amplitude. A receiving system may comprise a different optical probe (63) which receives the permeating beam from the optical probe and an optical probe control device which receives the feedback control signal from the photoelectric converter supplied with a different permeating beam from the different optical probe. In this event, the optical probe control device controls the different optical probe so that a different beam intensity of the different permeating beam is approximately equal to a constant beam intensity regardless of the input amplitude.

Title: Photosensitive driving device
Inventor: OGAWA TARO
IPC: F24F11/00
Filed: 1995-02-07
Granted: 2001-01-30
Abstract: An object of the present invention is to provide a simple, economical and safe driving device which is automatically activated by detecting solar light and an automatic ventilation system utilizing the aforementioned driving device. The electric motor (21) is connected to the 1-circuit 2-contact type relay switch (22), which is connected to the 1-circuit 2-contact type limit switch (23) and the 1-circuit 1-contact type light sensor switch (24). The limit switch (23) is connected between the relay switch (22) and the power supply and the manual main switch (25) between the light sensor switch (24) and the power supply. Normally when the main switch (25) is "on" and solar light exceeds the threshold of 35,000 lux, the light sensor detects it and the contact of the switch (24) changes from "a" to "b" to be activated. Electricity is then supplied to the relay switch (22) and the contact of the relay switch (22) also change "a" to "b" to be activated. If the contact of the limit switch (23) it at "b", electricity is supplied to the electric motor (21) to activate it. The electric motor is interlinked with the vent cover via the power transmission and the vent cover gradually begins to open. A specific time after the electric motor (21) is activated and the limit switch (23) comes in contact with the power transmission, then the limit switch's (23) contact changes from "b" to "a" to turn itself off. Thus the electric motor stops and the vent cover interlocked with the electric motor can stay open without operations of the manual switch. The main switch (25) normally stays in the "on" state, however, it can serve as a safety switch to forcibly shut down the system in the event of long-term shut down and maintenance.
