Title: Process for monitoring a disperse system for non-dispersed impurities and device for carrying out said process
Inventor: STUCKI FREDI
IPC: G01N23/12
Filed: 1997-02-21
Abstract: The invention relates to a process for monitoring a disperse system for nondispersed impurities (16) before processing of said system into an end product. During said process, part of the disperse system is extruded before processing to form a strip (7) and the impurities in said strip are detected. To this end, weak X-rays are beamed through small areas of the strip (7) continuously or gradually and at right angles to the strip plane. The X-rays emerging from the areas of the strip through which they have passed are subsequently detected in areas. The type, number, size, shape and/ or distribution of the impurities (16) are determined by the detected rays. It is particularly advantageous that impurities inside the strip and also on the surface thereof are detected as a result of X-rays passing through the strip (7). If the impurities (16) exceed a predetermined threshold, the disperse system does not undergo further processing.

Title: Iron-casein complex and process for preparing the same
Inventor: HAMASHITA KAZUMASA
IPC: C07K1/113
Filed: 1997-03-24
Abstract: An iron-casein complex which does not give an astringent taste peculiar to iron even upon heat sterilization and has a high iron-replenishing effect. It can be prepared by mixing three solutions, that is, a solution (A) containing carbonic acid, bicarbonic acid, or a mixture of them, a solution (B1) containing iron, and a solution (B2) containing a casein, in a suitable order.  In this case, however, the coexistence of carbonic acid, bicarbonic acid and iron only should be avoided. The iron-casein complex contains 1 to 1,000 atoms of iron and at least one molecule of each of carbonic and bicarbonic acids per molecule of the casein, and does not give an astringent taste even upon heat sterilization. It has a higher antianemic effect than inorganic iron salts.

Title: Regulation of apoptosis and in vitro model for studies thereof
Inventor: WANG XIAODONG
IPC: C12Q1/37
Filed: 1997-07-11
Abstract: A cell-free system based on the cytosol of normally growing cells, which reproduces measurable aspects of the apoptotic program, is provided. The apoptotic program is initiated by addition of dATP in the specific exemplification of the HeLa 100,000 x g supernatant. Fractionation of the cytosol yielded a 15 kDa protein, identified by absorption spectrum and protein sequence as cytochrome c, that is required for in vitro apoptosis. Elimination of cytochrome c from cytosol by immunodepletion or inclusion of sucrose to stabilize mitochondria during cytosol preparation, diminished the apoptotic activity. Addition of exogenous cytochrome c to cytochrome cdepleted extracts restored apoptotic activity. Cells undergoing apoptosis in vivo showed increased release of cytochrome c to their cytosol, suggesting that mitochondria may function in apoptosis by releasing cytochrome c.

Title: Side-tone otdr for in-service optical cable monitoring
Inventor: MAYBACH RICHARD L
IPC: H04B10/08
Filed: 1997-10-09
Abstract: An OTDR provides both in-service and out-of-service measurement information for an optical transmission system with multiple repeaters (34, 44). The repeaters include an optical high-loss loop back (hllb) path and an OTDR path.  The OTDR (30) is coupled to the input lines of the optical transmission system via an optical coupler so that both traffic signals and test signals from the OTDR (30) can be transmitted simultaneously. When the OTDR (30) is provided in-service measurement information, test signals in the form of side-tone pulses are transmitted on the transmission system. The OTDR (30) filters out the traffic signal from the return signal. The HLLB path (40) through the amplifier pairs of each repeater is distinguishable in the filtered return signal. When the OTDR (30) is providing out-of-service measurement information, the level of the side-tone pulses is increased because interference with the traffic signal is no longer a concern.

Title: Remote drop box lubrication circuit for tractors
Inventor: KOWALYK VLADIMIR M
IPC: F16H61/46
Filed: 1999-11-03
Abstract: A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system. Load sensing hydrostatic drive systems can encounter vibrational or surging problems, particularly when flow compensators in valving interact with the flow compensator of the hydraulic pump. This interaction will cause rhythmic flow pulsations or surging within the hydraulic system, which is undesirable. Stabilizing the hydraulic system can be accomplished with an attenuator/hose assembly.
