Abstract: An apparatus for controlling the access of a plurality of microprocessors at a data line. The microprocessors are connected by interface components or blocks, logic switching circuits and bus drivers with two lines or conductors. An access request or demand of a processor initiates a signal change at the first line. This signal change causes the transformation of data which is specific to the processor into a delay or a priority signal, upon the occurrence of which there is accomplished a signal change of the second line. As a function thereof there appears at an input of the interface component a signal change which is indicative of the availability of the data line. Upon simultaneous occurrence of access requests or demands of a number of processors the signal change of the second line is brought about by that processor whose priority signal possesses the smallest delay. The signal change of the second line prevents the occurrence of the priority signals possessing the greater time-delays and which are correlated to the remaining processors. At these processors there thus cannot occur any signal change at the input of the related interface component or block and which indicates the availability of the data line.

Abstract: A screw-extruder for shaped food pastes such as spaghetti is removably mounted on a base containing a prime mover. To ensure the safety of the assembly an activator is associated with the cylinder housing the screw and can only actuate a switch in the base when the cylinder is correctly positioned. The actuator may take the form of a manually operable pushbutton on the cylinder, or a lever acted on by the cylinder and acting as a mechanical interlock with a pushbutton and permitting its operation only when predetermined conditions are satisfied. In each case the pushbutton will only act to permit operation of the motor when it is properly positioned relative to a switch in the base.

Abstract: Inspection of a fusion splice between the ends of two optical fibres, said splice being reinforced by a support member, is facilitated. In particular, inspection of the joint between the optical fibre cores in a fusion splice is facilitated. The splice is held in a transparent support member by means of a transparent adhesive matched in refractive index to the cladding of the fibre. Apparatus is described which allows the splice to be viewed in two directions at right angles by means of a microscope whose position may be adjusted therefor without rotation relative to the support member. The arrangement is of particular relevance to splices between monomode fibres whose small core diameters call for a high degree of precision in jointing in order to avoid optical loss.

Granted: 1989-02-01
Abstract: An improved process for removing resin smeared on an interior wall of a hole in a resinous substrate and/or adhesion promoting the substrate which comprises: (a) contacting the substrate with an alkaline permanganate treating solution having a pH between about 11 and about 13 and an elevated temperature for a time period sufficient to remove the resin smear; (b) neutralizing essentially all manganese residue on the substrate; (c) contacting the substrate with an alkaline hydroxide etchant to remove the balance of manganese residue on the substrate. A metal such as copper subsequently may be electrolessly deposited in a more efficient and easily controlled manner on the resin substrate in the formation of a wire scribed circuit board or multilayer printed circuit board. In addition to resin smear removal, the process results in an improved bond between copper and the hole wall.

Granted: 1992-09-16
Abstract: The inventive concept provides an immunoassay using an enzyme label, in which the detection of the unknown substance is performed colorimetrically directly upon a solid surface. Preferably, the surface is an impermeable surface of a dipstick. To detect antigen in a biologically derived fluid sample, a dipstick containing bound antibody may be contacted with the sample and with a soluble enzyme-labeled antibody, to cause the antigen to bind to both the immobilized antibody and the labeled antibody on the surface. After separation of unreacted reagents, the solid surface is contacted with a substrate which converts from a soluble form to an insoluble colored form in the presence of the enzyme and deposits upon the surface of the solid surface. The solid surface is separated from the solution. The sandwich immunoassay technique may also be employed to detect antibody in the sample by reversing the roles of the antigen and antibody. The system is also applicable to a competitive binding technique. The invention further includes a colored dipstick produced by this means.
