Abstract: The invention pertains to medicine, specifically to methods of obtaining biologically active substances with immunoregulatory properties, and can be used in medicine, veterinary science and experimental biochemistry. The problem addressed by the invention is that of producing a novel synthetic biologically active peptide with immunoregulatory properties of formula X-A- D- Trp-Y, in which A is D-Glu, iD-GLu; X is H or Gly, Ala, Leu, Ile, Val, Nval,  Pro, Tyr, Phe, Trp, D-Ala, D-Leu, D-Ile, D-Val, D-NVal, D-Pro, D-Tyr, D-Phe,  D- Trp, .gamma.-aminobutyric acid, -aminocaproic acid; Y is Gly, Ala, Leu, Ile,  Val, Nval, Pro, Tyr, Phe, Trp, D-Ala, D-Leu, D-Ile, D-Val, D-NVal, D-Pro, D- Tyr, D-Phe, D-Trp, .gamma.-aminobutyric acid, -aminocaproic acid, -OH or substituted amide (C1-C3). The method of producing the peptide involves the synthesis of glutamil-containing peptides in solution by scission of an internal anhydride of tributyloxycarbonyl glutamic (D or L) acid with the appropriate k-salt of D-Trp-Y. This is followed by chromatographic separatio n of the .alpha.- and .gamma. isomers. Further synthesis was carried out by building up a peptide chain using activated esters of tributyloxycarbonylami no acids.

Abstract: A sucker rod guide bearing with a cylindrical shaft having a threaded stud at each end is connected by couplings to adjacent sucker rods. The coupling has a flat end surface which directly contacts the shoulder of the guide bearing and provides for the transmission of the guide bearing. A vaned cylindrical wheel is slidably mounted over the guide bearing connecting shaft such that the wheel remains stationary while the bearing body rotates within it. The wheel has four vanes, each having a substantially semi- circular cross-section outline. Each vane has an internal lubrication groove running the length of the wheel and the wheel is notched at each end of the groove to allow passage of fluids and extraneous matters such as sand. Preferably the wheel and vanes are made of a very hard polypthalamide resin which resists sand embedment and mechanical failure.

Title: Actuator having electrostrictive braking element
Inventor: HANLEY MARK G
IPC: F24F13/14
Filed: 1998-05-08
Granted: 2001-02-27
Abstract: An electro-mechanical actuator maintains an external device to which the actuator is connected at an operating position when power is applied to the actuator, and allows the external device to return to a default position when the power is removed. Included in the actuator is a housing and an output coupling rotatably mounted thereon. The output coupling is configured to be connected to the external device and displaces the external device between the operating position and the default position. A driving device is mounted in the housing for providing a torque to the output coupling to displace the external device between the default position and the operating position when the driving device is energized. Also provided is a torque transmitting device for transmitting and changing the torque from the driving device to the output coupling. The torque transmitting device is cooperatively engaged to and is located between the driving device and the output coupling. Operatively connected to the torque transmitting device, a retracting device is configured for exerting a retracting force to return the external device to the default position via the transmitting device when the power to the actuator is removed. An important feature of the invention is a piezoelectric braking device for exerting a braking force on the driving device for maintaining the output coupling at the operating position against the retracting force exerted by the retracting device when the braking device is activated, and for releasing the braking force when the braking device is deactivated.

Abstract: An imaging self-referencing target tracker  (10)  for a laser weapon (12).  The weapon generates a first beam of radiation (14)  that engages a target  (16)  to form a beam hit spot  (20) thereon.    In  a  first  embodiment,  a  target  illuminator  (22) (variant 1) illuminates the target with a second beam of radiation (23a).   An optics subsystem  (30)  receives and separately images the first and second beams  (23b, 24) of radiation.   In a second embodiment, a blocking filter (40)  is implemented rather than an illumination  laser  to  pass  only  radiation  at   the  target wavelength,  thereby ensuring that the first and second beams of radiation are separately imaged.  A controller (32)  is programmed to steer the first and second beams of radiation to the desired target aim point  (18)  in response to information from the imaged first and second beams of radiation.   The tracker of the present invention tracks the laser hit spot relative to the actual target image in a closed loop manner,  thereby increasing the probability of accurate target engagement and resulting in a target kill.

Abstract: A magnetic recording and reproducing apparatus has a recording magnetic head and a reproducing magnetic head disposed on a rotary cylinder, and a magnetic head clogging detecting unit for detecting clogging of the recording magnetic head by monitoring the output of the reproducing magnetic head. In this magnetic recording and reproducing apparatus, for saving power consumption, magnetic head clogging is detected intermittently only in predetermined periods, and in other periods the operation of the head clogging detecting unit is stopped. As a method of stopping the operation of the magnetic head clogging detecting unit, the power supply of the magnetic head clogging detecting unit is turned off. The width and interval of detection periods and detection sensitivity of magnetic head clogging detection can be freely set by the user. Further, in the case of magnetic recording .and reproducing apparatus having plural sets of recording magnetic heads and reproducing magnetic heads disposed on the rotary cylinder for drawing plural track patterns on a magnetic recording tape, by changing over the outputs of the reproducing magnetic heads, and putting the outputs into the common magnetic head clogging detecting unit, in addition to the above method, the power consumption necessary for magnetic head clogging detection can be further saved.

Title: Method for vertical continuous casting of metals
Inventor: VUIGNIER ERIC
IPC: B22D11/14
Filed: 1998-01-07
Granted: 2004-03-16
Abstract: The invention relates to a method for automatic, vertical continuous casting of metals, in particular aluminium alloys, in a casting facility comprising several moulds . According to the said method, the liquid metal is fed from a furnace along a spout to the moulds and guided, via nozzles with adjustable through-flow, to the moulds which are initially closed off by the dummy blocks arranged on a lowerable casting table. The metal through-flow volume of each nozzle is adjusted individually for each mould on the basis o f an initial time (t0) and an initial metal level (N0) at which adjustment of the metal level begins, in such a way that the metal in all moulds at a pre-set starting time (t S) is at substantially the same starting level (N S) at which the casting table starts being lowered fo r the production of the metal strands. The metal level (N) is adjusted simultaneously during filling between the initial level (N0) at the initial time (t0) and the starting level (N S) at the starting time (t S) in all moulds on the basis of time (t) in accordance with a set-point curve N = f(t) which is identical for all moulds. The slope dN/dt of the set-point curve is greater in a range (A) starting from the initial level (N0) and smaller in a range (B) in relation to the starting level (N S) than themean slope (N S - N0)/(t S-t0) between the initial and the starting level.
