Filed: 1993-02-02
Abstract: The invention relates to elastomers and articles reinforced with 5 to 30 phr Chitosan particles having a diameter of 0.5 to 75 microns. In an illustrated embodiment, the Chitosan may be modified with an oxygen reactive group or a nitrogen reactive group to make the Chitosan more reactive with an elastomer. Also provided is an economical method of incorporating very fine Chitosan particles into an elastomer matrix. In the method Chitosan is dissolved in an acid and mixed with a coagulating liquid (for coagulating latex), and the mixture of chitosan/coagulating liquid is mixed with a latex solution to provide an elastomer/chitosan composite. The elastomer/chitosan composite may be used as formed or it can be used as a masterbatch and mixed with more elastomer.

Abstract: An electronic locking arrangement comprising a lock unit (17) and a key unit (19) is proposed. Each of the units has a control circuit (35, 41) and a transmitting and receiving circuit (33, 47, 39, 43) which transmit information signals inductively via coupling coils (21, 23) to the control circuit (35, 41) of the other particular unit. The transmitting and receiving circuit of the lock unit (17) has an amplitude modulator (33) and a frequency demodulator (47) for the transmission of the information signals, whilst the transmitting and receiving circuit of the key unit (19) comprises a frequency modulator (43) and an amplitude demodulator (39). In dependence on the information signals transmitted between the units (17, 19), the control circuit (35) of the lock unit (17) generates a control signal representing the locking state. The transmission of the information signals takes place via a single pair of coupling coils (21, 23) utilised in both transmission directions. The amplitude modulator (33) modulates the high-frequency signal of a free-running high-frequency oscillator (27), the frequency-determining circuit of which comprises the coupling coil (21) of the lock unit, whilst the amplitude demodulator (39) is connected to the coupling coil (23) of the key unit (19). The frequency modulator (43) is likewise connected to the coupling coil (23) of the key unit (19) and detunes the frequency-determining circuit of the high-frequency oscillator (27) in dependence on the information signal to be transmitted. The frequency demodulator (47) is also coupled to the high-frequency oscillator (27). The locking arrangement permits high locking security, along with a high data transmission rate, at a comparatively low outlay in terms of structural parts. <IMAGE>

IPC: F16D3/12
Filed: 1993-08-26
Abstract: An improved coupling assembly (10) is provided for transmitting rotary power from the working end of an internal combustion engine (110) to a driven shaft (116). The crankshaft also has a free end (115) connected to an accessory drive train (118). The coupling assembly comprises a low inertia flywheel having a mass so selected as to cause the node of the first crankshaft mode of torsional vibration to be located in the vicinity of the middle of the crankshaft, and a flexible coupling which interconnects the working end of the crankshaft with the driven shaft. The low inertia flywheel not only reduces the amplitude of the torsional deflection at the free end of the crankshaft, but further raises the primary torsional vibration orders of the engine which excite the coupling assembly by at least one half of an order such that the peak stresses applied to the teeth of the first gear wheel of the accessory drive train are at least halved and are further applied to at least twice as many gear teeth, thereby greatly prolonging the life of the gear wheel. Moreover, the low inertia flywheel further increases the lifetime of the flexible coupling by raising its natural frequency to a level which is substantially higher than the 0.5 engine order of torsional vibration associated with engine malfunction and governor interaction.

Abstract: An improved method is disclosed for imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is a water-soluble halotriazine dye. The dye is reacted with a hydrophilic monomer to prepare a reactive dye containing predominantly monofunctionality. The monomer is then subjected to polymerization in the presence of a homogeneous solution of the reactive dye in the monomer under conditions to yield the hydrophilic polymer from which the lens is formed. The dye becomes bonded to the polymer during polymerization. 
     The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens. Furthermore, the lens does not need to be washed with aqueous base to bond the dye to the lens.

Abstract: La systémine, hormone peptidique comportant 18 acides aminés et première hormone polypeptidique découverte dans les plantes, provoque l'expression de gènes de défense dans des plantes déteriorées mécaniquement ou par des prédateurs, y compris des herbivores, des insectes, des bactéries et des virus. Le précurseur de la systémine est codé en tant que molécule de prosystémine comportant 200 acides aminés dont la séquence peptidique de systémine est située à proximité de la terminaison carboxyle. On a cloné à la fois un ADNc 951 bp pour la prosystémine et un ADN 4526 bp génomique et on a déterminé l'organisation du gène. Les plantes transgéniques réalisées à partir de l'ADN de prosystémine antimessager ne créent pas de réactions de défense contre la détérioration. Les plantes transgéniques réalisées à partir d'un nombre de copies amplifiées de gènes de prosystémine présentent une résistance améliorée à la déterioration. Les larves d'insectes se nourrissant sur les plantes transgéniques réalisées à partir d'un nombre de copies amplifiées de gènes de prosystémine présentent une diminution de leur poids de croissance par rapport aux larves se nourrissant de plantes de type sauvage.
