The invention relates to a method wherein uncured urethane formulations are bonded to a cured rubber or synthetic rubber substrate in such a manner so as to provide greater bonding strength than has been achieved previously in urethane formulation bonding to rubber or synthetic rubber. The substrate is cleaned, a coating of a cyanoacrylate adhesive is applied, followed by a liquid or paste urethan...

A latex that is devoid of formaldehyde-containing monomers in polymerized form, does not evolve formaldehyde nor decomposes to produce formaldehyde is used in the production of impregnated or treated paper and woven and nonwoven fabrics. The latex is produced by polymerizing a monomer charge containing at least one principal monomer and a crosslinking agent combination consisting of 0.1 to 10 weig...

In the impact-modification of polycarbonamides, the incompatibility of acrylic core//shell impact modifier with low molecular weight nylon is overcome by forming an impact modifier concentrate of impact modifier and high molecular weight nylon which concentrate is then mixed with a larger amount of low molecular weight nylon so as to modify its impact resistance properties.

Low density, closed cell, soft foam products having dimensional stability are made from ethylenic resin blends having low stiffness by extrusion foaming, wherein the heat plastified gel comprises the ethylene polymer blend and at least one volatile blowing agent. The blends especially comprise a copolymer of ethylene and monoethylenically unsaturated carboxylic acid and a copolymer of ethylene and...

A process and an arrangement for the production of molten pig iron or steel pre-products from particulate ferrous material as well as for the production of reducing gas in a meltdown gasifier. A fluidized bed of coke particles is formed by the addition of coal and the injection of oxygen-containing gas. In order to ensure a satisfactory mode of operation of the meltdown gasifier even if coal of in...

PURPOSE:To enable to form a uniform film on wafers by a method wherein process gas is uniformly fed in the process tube. CONSTITUTION:The group of through-holes 10 of a process tube 4 is provided in such a way that the through-holes on parts of the process tube 4, where are located near the intake vent 5 of a box 3, are formed of those of smaller diameters and the penetrated holes on parts of the ...

PURPOSE:To house a large-sized semiconductor chip by forming a bonding pad onto the vertical inner wall of a cavity in a ceramic package through metallizing. CONSTITUTION:In a multilayer type ceramic substrate 1, there is no bonding pad section in the width direction (the horizontal direction) as seen in conventional devices, and a vertical wall surface up to a cap 5 from the base of a cavity is s...

1-N-[ omega -amino- alpha -hydroxyalkanoyl] kanamycins A and B of the formula I in which R represents OH or NH2, are prepared by acylation of polysilylated kanamycin A or B, or polysilylated kanamycin A or B which has a protective group other than silyl on the 6'-amino group, with an acylating derivative of an acid of the formula II in which n is an integer from 0 to 2 and B is an ...

PURPOSE:To secure the reliability of a device and to improve the operating ratio by resetting an interface (I/F) circuit to stop the output to the external if troubles exceeding a prescription are detected in a certain time. CONSTITUTION:When a trouble occurs in a CPU11, a self-diagnostic circuit 21 resets the CPU21, and contents of a counter circuit 22 are increased by +1. Though the CPU11 is res...

To provide for uniform pressure, under predetermined conditions, of application of closure sealing jaws for a bag making machine, to close thermoplastic tubular foils, a hydraulic pressure element (7;26,28) applies the pressure of a pressure jaw (1) against another (2), with the foil interposed; the hydraulic pressure is sensed by a transducer (11), converted into an electrical signal and compared...

PURPOSE:To efficiently drive an elastic wave motor with a low voltage by uniformly disposing a drive source over the entire periphery of an elastic unit. CONSTITUTION:An A-phase made of piezoelectric units 31-312 is provided over the entire periphery of one surface of an elastic unit 1, and a B-phase made of piezoelectric units 313-324 is provided by the phase difference of lambda/4 from the A-pha...

A fluid absorbing product, for instance a sanitary towel, a brief shield, an incontinence shield, a napkin, etc. is manufactured from a core (17) of an absorbing material know per se and a carrier material (11) which is extrusion strip coated. A portion of at least one strip (30, 31) of thermoplastics defines the penetration portion (-s) (32, 33, 34, 35, 36) of the product. The placement of the co...

Optical axes of the day path and of the night path extend in a sagittal plane (5,9) of the carrying vehicle and the passage from the night path to the day path or conversely is effected by means for displacing a first reflector parallel to the plane in order that the input light beams are directed to the optical axis of the day path or of the night path. A second output reflector along the optical...

The apparatus contained in a single housing (1) comprises a first movable input reflector (4) and a second input reflector (5) for causing the input light beams to deviate along the optical axis (11) of the night path and optical axis (7) of the day path, respectively. The night path is constituted by an objective (12), a light intensifier tube (13) and a bent ocular (14) and the day path is const...
