Abstract: ABSTRACT OF THE DISCLOSURE           Ions are implanted into a body, such as semi-conductor substrate material, through one or more covering layers formed over the body.  A thin conductive film is in contact with the covering layer prior to the ion implanta-tion. The ions are implanted into the material through the thin conductive film.  The conductive film functions to conduct away any charge which tends to accumulate in the covering layer.  The conductive film thereby prevents a charge accumulation which would tend to discharge through and cause damage to the covering layer.  The method is particularly useful for fabricating MOS and CMOS semiconductor devices.

Abstract: Abstract of the Disclosure A first dye is applied to spaced regions of a tufted carpet and a second dye is then applied to a substantially larger area of the carpet including the spaced regions covered by the first dye.  The second dye is absorbed by the carpet in the regions outside of the already dyed regions.  But the second dye has a viscosity sufficiently lower than the vis-cosity of the first dye that the fibers in the spaced regions are substantially masked from and substantially do not absorb the second dye. The carpet is then steamed to fix the dyes to the yarn.

Abstract: D-21,023 REGULATING AMPLIFIER   by Otto G. Wisotzky and Tom L. Blackburn ABSTRACT OF THE DISCLOSURE           An AC input signal and a DC supply voltage are applied to a tapped coil having end points from which differential input signals are coupled to a differential variolosser that controls the gain of cascaded differential amplifiers.  The two output terminals of the cascaded amplifiers are electrically connected together through a pair or equal valued resistors to provide a DC reference voltage at the junction of the two resistors, where the AC signals cancel.  The reference voltage is coupled to one side of a high-gain differential control amplifier and to both sides of a differential half wave rectifier circuit.  One side of the rectifier is also connected to one output of the cascaded amplifiers for detecting an amplified signal there.  The detected signal is integrated and coupled to the other side of the control amplifier to produce the control signal which regulates the drive current to and loss presented by the variolosser, and thus the level of the input signals to the cascaded amplifiers.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a method and apparatus for obtaining a precise aliquot of a sample by diffusing the sample into a gel mass for a controlled period of time.  The sample may comprise a liquid containing an unknown quantity of a diffusible, to-be-assayed, component or components.  The method may further include reacting a component of the sample with an assay-reagent present in excess quantity above that needed for reaction, the reagent being disposed in the gel mass.  The sample is placed in contact with a preselected surface area of the gel mass.  The component of the sample is allowed to diffuse into the gel mass for a controlled period of time.  Thereafter, the remainder of the sample containing the component is removed, and further diffusion of the component through the gel mass may proceed for a controlled period of time.  This provides both a further dilution of the component and permits continuous reaction of the component with a reagent distributed throughout the gel mass.  It is possible to measure the degree of reaction between the diffused component and the reagent in the gel mass.          Alternatively, the method may involve obtaining an aliquot of a sample containing an unknown quantity of a diffusible, to-be-assayed component as above, but without requiring further dilution via diffusion.  Also, there may be no need for any assay reagent and a property of the to-be-assayed component such as color, fluorescence, etc. may be measured directly in the gel mass.  In another embodiment, the invention may be practiced so as to obtain a precise aliquot of a sample or of a reagent by diffusing them into a gel mass for a controlled period of time.

Abstract: ABSTRACT OF THE DISCLOSURE     An amusement device consisting of a toy wheeled vehicle and a trackway on which the vehicle moves.  In the preferred embodiment, the wheeled vehicle has at least rotatably driven rear wheels, rotatably driven gears and at least one rod extending from the vehicle.  The trackway includes six different track sections which, when cooperating with the vehicle, impart differ-ent types of movements to the vehicle as the vehicle moves along the trackway.  In one track section, for example, the front end of the vehicle is elevated into an upwardly extending position.          The vehicle is movably driven on the track section by the rear wheels in the upwardly extended front end position until it reaches a portion of the track section which returns the front end of the vehicle to a normal position.  In another track section, there is provided a double-inclined tower which imparts a rocking movement to the vehicle as the vehicle moves upwardly on one side of the tower.  As the vehicle moves downwardly on the opposite side of the tower, the vehicle rotates in a somersault fashion about the gears from gravity and vehicular mass momentum until the vehicle reaches the trackway at the tower bottom.  In yet another track section, the vehicle is imparted with an S-shaped movement along that section.  In still a further track section, the vehicle is tilted sideways and moved along the section in that tilted position until it is returned to its normal position on the trackway.  In still another track section, there is a tower which the vehicle climbs substantially vertically upward to an elevated level and then somersaults from a spring-action ramp at that elevated level onto the trackway below to a normal position.

Abstract: Apparatus For Splicing Ends Of A                Grooved Sheave Insert Member Abstract Apparatus for splicing ends of a sheave insert material in which the ends of a premeasured length of an elastic, thermoset sheave insert material are laminated together in a special splicing jig for fabricating a unitized insert loop, which is sub-sequently stretched around a sheave into a preformed insert receiving slot along the circumference there-of.  The jig holds the ends of the premeasured length of insert material in alignment as a heated mold, included therein, fits snugly around the ends and applies heat to the joint therebetween, into which the insert material, in liquid form, has been inserted to join the ends.  The heat thus applied to the joint accelerates the curing of the liquid into the same consistency as the insert; thereby producing a unitized bond between the ends by which the unitized loop is thus formed.
