Patent CA-2037158-C (CA)
Title: Output buffer circuit
Inventor: SHIODA FUMIO
IPC: H03K19/00
Filed: 1991-02-27
Granted: 1996-08-06
Abstract: An output buffer circuit which supplies logic signals at an emitter-coupled-logic (ECL) level is realized by a CMOS process. The logic signals are supplied to the gate electrodes of a first P-channel CMOS transistor and a first N-channel CMOS transistor connected in series, and their common drain output is supplied to a second P-channel CMOS amplifying transistor having an open drain configuration. Between the output terminal of the P-channel CMOS transistor and an external power supply terminal is a first resistor. A voltage regulating means, connected between the output terminal and the external power supply terminal, regulates the output voltage at the output terminal. In the voltage regulating means, a voltage setting circuit produces a desired voltage using the voltage on the external power supply terminal. A control voltage generating circuit uses the desired voltage to generate a control voltage which acts through a regulating driver circuit to regulate the voltage at the output terminal.

Abstract: A folding utility tool has a handle consisting of a first side and a second side spaced apart by a plurality of spacers.  The area between the first side and the second side of the handle provides a first recess within the handle above the spacers and a second recess below the spacers.  A pair of pivots, one at each end of the handle, allow a plurality of tools to be pivoted from a nested position between the handles to an extended position beyond the handles.  The tools may include such conventional devices as knife blades and screwdriver-can opener blades.  At least one of the tools, however, is a pair of locking pliers having a first jaw and a second jaw pivotable about one of the pivots.  The first jaw is lockable in an extended position while the second jaw is adjustable and pivots about the same pivot point as the first jaw.  An actuation lever and a reaction member provide an over-center mechanism to allow the pair of pliers to be locked with one jaw in a given position relative to the other jaw.  The actuation lever has an adjustment mechanism which allows this relative position to be preadjusted for grasping various objects.

Title: Method and apparatus for the manufacture of j-shaped display hooks with balled ends
Inventor: NAGEL THOMAS O
IPC: B21F5/00
Filed: 1991-08-27
Granted: 1994-01-11
Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus is disclosed for the manufac-ture of J-shaped display hooks with balled ends in a single  manufacturing  operation,  without  requiring separate handling of the display hook for the bending and ball-forming operations.   A continuous length of wire  is  advanced  incrementally  and  gripped  tightly adjacent its forward end.  The wire is severed by means of a cutting and forming bar, which also bends the base portion of the wire at right angles to the main axis of the wire.  While the wire remains tightly gripped at its forward end, and continue to be supported adjacent its base by the cutting and forming bar, a ball-forming die is advanced against a projecting forward end of the wire, upsetting the wire end and forming an enlarged end of  generally  spherical  configuration.    Immediately thereafter, the wire is released at its forward end, and a rotary plate  is actuated,  causing a bend-forming element to travel through a generally circular path concentric to a cylindrical forming drum.  This opera-tion, which is carried out while the base portion of the wire  remains  locked  in position,  forms a generally semicircular bend in the previously balled end of the wire.   Both the ball-forming operation and the hook-forming bend are carried out in sequence, while the remainder of the hook remains locked in position and oriented in a predetermined manner, so that the various elements of the resulting hook are properly shaped and aligned.

Granted: 1996-11-12
Abstract: A process for rendering usable disposal products is described, in whichunsorted pollutant-containing industrial, domestic and/or special refuse undergoes a high temperature treatment.  Accompanied by the entraining of existing liquid fractions and whilst maintaining its mixed and combined structure, the disposal product is compressed batchwise to compact packs. Whilst maintaining the pressure action it is subsequently positively intro-duced into a channel heated to over 100°C and is kept in sliding, non-positive contact with the channel walls until the initially present liquids are evaporated and mechanical restoring forces of individual disposal product components are eliminated. The entrained organic constituents at least partly assume a binder function.  The shape and structurally stable, lumpy solid conglomerate forced out of the channel in this state is intro-duced into a high temperature reactor maintained at at least 1000°C and forms therein a gas-permeable bed.

Title: Dipping composition for the treatment of chromatized or passivated galvanizing coatings
Inventor: FLAMME BURKHARD
IPC: B05D7/00
Filed: 1992-11-16
Granted: 2002-12-17
Abstract: A dipping composition for the treatment of a chromatized or passivated zinc or zinc alloy coating deposited on a steel substrate is disclosed. The composition comprises titanic, acid esters, titanium chelates or mixtures thereof, organo-functional polysiloxanes and a solvent selected from the group consisting of organic solvents, preferably alcohols and hydro-carbons, water and mixtures thereof. The weight ratio of titanic acid esters to polysiloxanes in the composition is from about 1:1 to about 1:4. Using the composition, a coating having thickness of, for example, 4 to 6 microns can be applied using a dipping process, which coating is subsequently dried at 80°C and burnt in at up to 250°C. The coating so obtained provides corrosion protection times at least 5 to 10 times longer than those which may be achieved without it. In particular, it can be used to improve the corrosion resistance and durability of chromatized coatings obtained using chromium III compounds, which chromatizing, normally less durable than that obtained using chromium VI com-pounds, is preferred because of its lesser environmental impact.
