Title: Hot melt adhesive for polyethylene film reinforcement
Inventor: CHEN FRANKLIN M C
IPC: A61F13/58
Filed: 1988-05-16
Granted: 1992-11-24
Abstract: ABSTRACT      An article having a refastenable tape system comprising a flexible substrate having a tear strength, and an adhesive tape member having a peel adhesion value which is greater than the tear strength of the substrate when the tape member is adhered to a first major surface of the substrate.  A reinforcement layer composed of a hot melt adhesive is bonded to a second major surface of the substrate located opposite to the first major surface.  The reinforcement layer exhibits an elongation-at-break of at least about 100%.  The substrate and the reinforcement layer thereby provide a composite tear strength greater than the peel adhesion value of the tape member, and provide a composite elongation-at-break of at least about 100%.

Granted: 1992-10-27
Abstract: Abstract Detachable printing unit for offset printing presses A detachable printing unit for offset printing presses  which can be incorporated during their manufac-ture or fitted to existing presses  said unit being defined in that it is composed of an independent inking module 16 (Figure 3) comprising all the components required for effecting in chronological operating order the moisten-ing and inking of an offset plate ready for printing on a blanket  and a likewise independent detachable blanket cylinder 7C.       One embodiment of the invention is defined in that the numbering device with which the press is equipped (Figure 6  View B) is replaced by the blanket cylinder (Figure 7  View B) of the printing unit working with the inking module 16 (Figure 3)  and use is made of the drive mechanism 8 (Figure 6) and pressure adjustment mechanism 9B provided in the press to obtain for each printing cycle  instead of the numbering  an additional color obtained by color superimposition with the aid of the pressure cylinder 4.       In the other form of the invention the same ink-ing module  disposed in another position in the press works conjointly with the blanket cylinder 3 of the press to enable for each printing cycle an additional color and optionally letterpress numbering or an addi-tional letterpress color to be achieved.

Title: Antireflection solution for optical parts and method of antireflection treatment using said solution
Inventor: KATO HIROHISA
IPC: G02B1/10
Filed: 1988-08-02
Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE    This invention is directed to an antireflection solution having as a main film-forming component thereof a hydrlytic derivative of a silicic ester and to a method for the treatment with the antireflection solution.  The antireflection solution and the method for the treatment therewith are characterized by the fact that the hydrolytic derivative of silicic ester is obtained by causing a mixture consisting of the silicic ester and hydrolyzing water added thereto in an amount exceeding the chemical equivalent relative to the silicic ester to be hydrolyzed in the presence of a solvent compatible with both of the components of the mixture and further subjecting the resultant hydrolyzate to conversion into a colloid solution under the condition of pH 3 to 7.  Owing to the characteristics mentioned above, the present invention permits the antireflection film produced by thermally solidifying an applied layer of the anti-reflection solution at a low temperature in the neighborhood of 100°C to acquire notable improvement in film properties such as resistance to defilement and adhesiveness to the substrate.

Abstract: CONTROL OF ENERGY USE IN A FURNACE    ABSTRACT OF THE DISCLOSURE            A microprocessor control determines, in the course of initiating a heating cycle, whether the blower is operating in the continuous mode, and if it is, the control prompts the blower to be turned off prior to the ignitor being turned on. In this way, the blower and ignitor are never on at the same time and the instantaneous total current draw is limited to thereby reduce the occurrence of burned out fuses or circuit breaker trips.

Title: Fiber-optic reed switch
Inventor: RANDO JOSEPH D
IPC: G02B26/02
Filed: 1989-01-19
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE A magnetically responsive reed switch assembly having one or two cantilevered reed members arranged to close and open a gap responsive to respective levels of magnetic exposure, supports two optical fiber members in end-to-end closely spaced confrontation with the common axis alignment or misalignment of the fibers being a function of the relative closed or opened gap condition.  A convenient method of fabrication involves mounting opposing cantilevered reed members on a substrate which is bent to bring the reed members closer together longitudinally.  While so bent, a gap closing magnetic field is generated and a continuous length of optical fiber is bonded to the flat aligned surfaces of the reed assembly.  The fiber is scored, broken at scoring, and s?ress and magnetic field is relieved, whereupon fiber ends shift laterally to produce open circuit condition.

Abstract: @ A vortex cleaner for separating fibre-liquid-suspensions, and in particular paper-pulp suspensions, into fractions, comprises an elongate vortex chamber (1) of circular cross-section, which over a part (3) of its length tapers towards its one end. At the wider end of the chamber there is provided a substantially tangentially directed inlet (4) for the suspension to be treated, and an axially directed outlet (6) for a lighter fraction of the treated suspension. At the narrower end of the chamber there is provided a second, axially directed outlet (7) for a heavier fraction of the treated suspension. The chamber is provided, within its narrowing part (3), with a plurality of baffles (9) which project radially into the chamber from the inner surface of the chamber wall, and which are inclined relative to the axial direction of the chamber substantially in concordance with the helical flow of suspension fed through the tangential inlet (7) and passing nearest the chamber wall towards the narrower end of the chamber, These baffles are mutually spaced apart when seen in both the axial and peripheral direction, in a manner such that the upstream end of a given baffle is located at a peripheral and/or axial distance from and downstream of the downstream end of the immediately preceding baffle. In this way, the baffles ensure that the heavier fraction is discharged through the reject outlet (7) at the narrower end of the chamber, so as to obviate the risk of the vortex cleaner being blocked, without impairing the fractionating process in the vortex cleaner at the same time.
