5 NOVEL PEPTIDE / SUNTORY LTD
(NEW MATERIAL) A peptide consisting of 13 amino acids: L-tryptophan, D-histidine, L-tryptophan, L-leucine, L-glutamine, L-leucine, L-lysine, L-proline, L- glycine, L-glutamine, L-proline, L-methionine, and L-tyrosine, in the order mentioned. (USE) Peptides having the actions antagonistic to the physiological action of peptide capable of readily distinguishing the a-type cells having the sexual genes of yeast from α-type cells [disclosed in the Japanese Application No.53-72430 (1978) by the same applicant], and the action to prevent the sexual transformation of a or α-type cells during storage. (PROCESS) The peptide is obtained from Boc-Trp-Leu-Gln-Lys(Zoc)-Pro-Gly- Gln-Pro-Met-Tyr(2,6-Cl2 -Bzl)-OBzl, by the well-known method.
6 Dyed materials / The Secretary of State for Defence in her Britannic Majesty s Government of the U.K. of Great Britain & Northern Ireland (GBX 07)
A method is provide for dyeing a non-cellulosic organic material with a dye, preferably a vat dye, comprising (a) treating the material with a dye in the presence of a reducing agent and an alkali and (b) oxidising the treated material produced in step (a) characterised in that the concentration of reducing agent used in step (a) is increased above that used for conventional vat dyeing such that the resultant dyed material has a lightfastness of 5 or more by BS1006 B01 and B02 (1978) and/or has a washfastness of 5 or more by British Standard Test BS1006 CO6.C2 (1981). Preferably the step (a) is carried out in the presence of an alkali in concentration of greater than 0.1 molar, more preferably a concentration of 0.2 molar or more and most preferably greater than 1 molar. The method provides vat dyed non-cellulosic organic materials having a reflectance of infra-red light of wavelength 400 nm to 680 nm of less than 15%.
7 Mechanical seal / Taiho Kogyo Co., Ltd. (Aichi JPX 03)
A mechanical seal comprises a seating ring and a follower ring. The seating ring receives therethrough a rotatable shaft and forms a stationary member and the follower ring is rotated together with the rotatable shaft in sliding contact with the seating ring. The seal is serviceable for avoiding the leakage of pressurized sealed fluid from the outside of the sliding contact portion between both the rings to the inside thereof. At least one of the sliding contact surfaces of both the rings has an outside raised portion along the periphery of the sliding contact surface. The raised portion is swollen in the direction of the axis of the rotatable shaft as compared with the inside portion of the sliding contact surface. Since the contact surface pressure in the peripheral portion of both the rings becomes high at the normal temperature by the provision of the outside raised form, the sealing effect can be improved especially during the stoppage of the follower ring. When the follower ring is subjected to the frictional heat due to its rotation, the follower ring is deformed in the direction in which the contact surface pressure becomes even. Therefore, the effect of sealing during the rotation is also improved. ,,p This is a continuation, of application Ser. No. 133,713 filed Mar. 25, 1980, in turn a continuation-in-part of application Ser. No. 895,072, filed Apr. 10, 1978 both of which are now abandoned.
8 Kalman equalizer / Kokusai Denshin Denwa Co., Ltd. (Tokyo JPX 03)
An improved Kalman equalizer for providing a tap weight of a transversal filter for equalizing a transmission line has been found. A complex number fast Kalman equalizer (FIG. 27 ), which is the improvement of the prior fast real number Kalman equalizer (see; “Fast calculation of gain matrices for recursive estimation schemes”by Lennart Ljung, et al, INT. J. Control, 1978, vol. 27, No. 1, 1-19), has a complex conjugate generator (C 2 ) for processing a complex input signal so that an equalization can be performed on the bandwidth division concept, and a transmission line having a complex impulse response can be equalized. Then, a bandwidth division equalization in which a whole bandwidth is separated into a plurality of sub-bandwidth each being equalized by a related sub-equalizer becomes possible. Also, a QAM signal (Quadrature Amplitude Modulation) which has a complex impulse response can be equalized. A bandwidth division fast Kalman equalizer (FIG. 68 ) is also possible as the modification of the present invention.
9 Sealing device / American Casting and Manufacturing Corporation (Plain View NY 02)
The invention is an improvement over my copending application Ser. No. 951,569 filed Oct. 15, 1978 now U.S. Pat. No. 4,223,423, granted Sept. 23, 1980, and relates to a sealing device, which is particularly useful with a receptacle, such as a cloth bank bag for containing money or currency. The sealing device comprises a single strip or band of material made of metal or plastic and formed with teeth or serrations, which extend from one side of the band and includes locking projections engaging with the teeth or serrations in an improved manner for securing the band in its closed position. The locking teeth are stamped, or otherwise formed in the material near one end of the band, so that the other end of the band may be inserted through slits in the band, whereby a number of teeth engage with locking elements when the band is tightened around the neck of the bag. Movement of the end of the band is thereby prevented in the direction which would unlock the seal but is freely permitted in the other direction for the extent of the teeth so that a tight seal may be accomplished. Once sealed, the sealing device cannot be released without tearing or mutilating the bag material or damaging the sealing device.
10 Diaphragm valve / Waterfield Engineering Limited (Hampshire GB2 03)
A diaphragm valve has a body defining a fluid passageway and, in the wall of the body, an opening in communication with the fluid passageway. A diaphragm for controlling fluid flow through the passageway extends across the opening and its periphery is clamped between the body and a bonnet secured to the body. Around the opening in the body is a diaphragm seating formed by two flat surfaces inclined relative to each other so as to be divergent. The bonnet is also provided with a diaphragm seating which comprises two flat surfaces inclined relative to each other so as to converge at the bottom end of the bonnet. The diaphragm seating is such as to provide a straight-through fluid passageway which, at each end of the body, is of circular section, these sections being joined by an elliptical or substantially elliptical section. This is a division of application Ser. No. 900,393, filed Apr. 26, 1978, now abandoned.
