Abstract: A substantially solvent-free adhesive composition consists essentially of an elastomer and tackifier, a metal oxide and, optionally, a plasticizer. The elastomer is selected from the group consisting of polar elastomers and unsaturated elastomers which have at least 5 mole percent unsaturation, said elastomer being a non-crystalline elastomer or an elastomer which has a slow rate of crystallization such that after a time period of at least 100 hours has elapsed following subjecting the elastomer to a temperature of 70°C for 30 minutes, the elastomer has a room temperature Shore A hardness of less than 60. The adhesive compositions can be formed into a shaped article, such as of a tape, film, sheet or tubular sleeve, if desired. The compositions have high adhesive strength for bonding together a variety of substrates. The adhesive is particularly useful with a dimensionally recoverable article, such as a shrinkable sleeve, to bond the recovered sleeve to a substrate such as an electric cable.

Abstract: A process and a device for converting a periodic LF voltage into sound waves, or vice versa. The electro-acoustic transducer device has two groups of substantially parallel points which are separated by insulating screens. The points of each group are respectively connected to the positive terminal and to the negative terminal of a source of DC voltage, of the order of 10,000 volts, which renders the points emitters of an ion plasma. The DC voltage is modulated by a periodic LF voltage. The ion plasma oscillates and creates sound waves which analogically reproduce the LF voltage. This technology is particularly applicable to the construction of loud-speakers.

Abstract: Ethylenediamine tetraacetic acid is prepared by forming an ethylenediamine formaldehyde adduct, cyanomethylat- ing the adduct with hydrocyanic acid at controlled temperatures to form ethylenediamine diacetonitrile. This is further cyanomethylated under acid conditions with formaldehyde and hydrocyanic acid in slight excess to form the ethylenediamine tetraacetonitrile. The precipitated product, with or without isolation is hydrolyzed to form the tetrasodium salt of the ethylenediamine tetracetic acid in a stock solution for further processing. The process, in semi-batch processing, provides yields above about 98% and in good purity. 
     When combined with ethylenediamine tetraacetic acid production, the process eliminates the need for cyanide waste treatment and greatly simplifies the procedures needed to nrotect the environment.

IPC: F01P7/08

Abstract: An improved fluid coupling device is disclosed of the type including modulating valving. The coupling device includes an input coupling member (11) and an output coupling member (13) which cooperate to define a plurality of annular lands (57 and 59). The input member defines a rearward surface (61) and the output member defines an adjacent surface (63), thus forming a bottom end clearance within the coupling. The input coupling member further defines an annular transverse surface (71) and a cylindrical surface (73) which cooperate to define an annular recess (75). As the air temperature is increasing, and the operating chamber (33) is being filled with fluid, the annular recess (75) prevents the bottom end clearance from filling with viscous fluid in a way which results in an undesirably rapid rate of increase of the speed of the output coupling member (13). As another feature of the present invention, the lands (57) defined by the input member include a plurality of radially outer lands (57a, 57b, and 57c) having an axial length less than the nominal axial length L of the remaining lands (57), to further reduce the rate of increase of viscous shear torque transmitted to the output coupling member.

Abstract: A reverse air jet cleaning system for impingement or porous media type air filter elements includes one or more specifically shaped cleaning air manifolds or heads in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush or flood the filter element to clean the dust cake from the exterior surface of the element. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air to thoroughly flush the surfaces of the filter element. The multiple jet orifice heads or manifolds may be configured in virtually any geometric shape to provide the desired jet pattern and are not limited to use in conjunction with cylindrical tubular type filter elements.
