Abstract: Abstract of the Disclosure A semiconductor component with electric contacts is formed which includes a semiconductor body having metal contact layers formed in ohmic contact with at least two side surfaces thereof.  In the process of making the component, a layer sequence is made including two layers formed of thermoplastic material and an intermediate layer of conductive material sandwiched between the two thermoplastic layers.  In the process the temperature of the semiconductor body is raised to soften the thermoplastic material and the semiconductor body with its metal contacts is pressed through one of the thermoplastic layers, through the intermediate conductive layer to rupture the same and divide it into two parts and partially into the other thermoplastic layer.  The intermediate layer is now composed of two parts, each part being conductively in contact with one of the metal contacts on the side surfaces of the semiconductor body.  By forcing the semiconductor body and the leads through one of the thermoplastic layers into a desired position in the other thermoplastic layer, the first thermoplastic layer referred to, when cooled, partially extends upwardly against the respective faces of the semiconductor body to firmly grip these parts in place against the other thermoplastic layer.  Furthermore, the metal contacts on the semiconductor body become fused to the two parts respectively of the intermediate conductive layer.  Lead wires to the intermediate conductive parts are provided by pressing them through the first mentioned thermoplastic layer into contact with the intermediate conductive parts and fused therewith.

Title: Automatic d-c offset cancellation in pcm encoders
Inventor: MEYER FRED
IPC: H03K7/00
Filed: 1977-07-14
Granted: 1981-09-15
Abstract: Abstract of the Disclosure During encoding of voice frequency (YF) signal in a PCM channel bank the encoder encounters direct current (d-c) offset component resulting from the particular VF signal.  Such d-c offsets cause errors above and beyond the normal encoders inherent in the normal encoding process.  The present invention alleviates this problem by providing an automatic d-c offset cancellation circuit which closely follows the d-c offset component and provides a d-c component of opposite sign to cancel it.

Abstract: ABSTRACT OF THE DISCLOSURE         A roller bit for rock drilling, provided with a bit body the upper side of which is provided with means for coupling to a drilling string, and the lower side of which is provided with a number of stub axles on which toothed cutting elements are mounted so as to be freely rotatable.  A locking ring for taper, cylindrical or the like bearing elements has a cylindrical surface capable of insertion into and fixing in a complementary cavity communicating with a race for bearing elements formed in the cutting element. The race is provided on the side which faces the bearing with a shoulder which axially locks the bearing elements and on the other end with a seating for a sprung washer which is connected to the stub axle.  A recess formed in the locking ring and communicating with the shoulder, forms a lubricant reservoir, and the seating chamber for the washer formed in the locking ring communicates through at least one channel in the body of the bit with the mud supply channel of the drilling string, to supply mud to the annular gap between the locking ring and the body of the bit thus preventing drilling debris from reaching the sprung washer on the bearing.

Abstract: ABSTRACT OF THE DISCLOSURE                  A highly efficient, shear-cutting, multiple die apparatus and method for interlocking elongated, multiple-sheet glued webs such as business forms or computer print out paper during fabrication thereof is provided which positively locks the web sheets against relative shifting an can occur when the web is zigzag folding, in order to prevent "tenting", or permanent, glue-set misalignment between respective web plies at the fold lines thereof.  The preferred apparatus in-cludes individual, mated pairs of rotatably mounted, transversely oriented, multiple-blade, pointed, web-shearing and deforming dies which are rotated to co-operatively engage, sheer-penetrate and deform a moving web to produce a series of transversely extending, side-by-side, marginal, alternately displaced inter-locking stripe which effectively prevent significant relative longitudinal shifting between the web plies. The blade tips of the cooperating dies interfit during the web-shearing and displacing operation and serve to provide equal support and driving force for the web on opposite side thereof, so that the web experiences minimum disturbance and no initiating causes for web skewing.  The blade tips are contoured such that the opposed ends of the shear-cut strips remain connected to the web, the thus provide the most desirable positive web interlock, even at high or varying web speeds.  In preferred forms, press-ironing rings are rotated with the interlocking dies for ironing the glued portion of the web in conjunction with formation of the interlock-ing strips.

Abstract: ABSTRACT OF THE DISCLOSURE      A specific binding assay method employing, as a labeling substance, a reversibly binding enzyme modulator for the detection of a ligand in a liquid medium.  The method follows conventional specific binding assay techniques of either the homogeneous or heterogeneous type wherein the liquid medium to be assayed is combined with reagent means that includes a labeled conjugate to form a binding reaction system having a bound-species and a free-species of the conjugate.  The amount of conjugate resulting in the bound-species or the free-species is a function of the amount of ligand present in the liquid medium assayed.  In the present invention, the labeled conjugate comprises a reversibly binding enzyme modulator covalently linked to a binding component of the binding reaction system. The distribution of the conjugate between the bound-species and the free-species is determined by addition of an enzyme whose modulator and measuring the resulting activity of the enzyme. The enzyme modulator may be a conventional enzyme inhibitor, preferably of the competitive type, or an allosteric effector.

Abstract: ABSTRACT OF THE DISCLOSURE     A modified organopolysiloxane composition is provided herein.  Such organopolysiloxane composition is obtained from the polymerization of (1) a monomer having ethylenic unsaturation in the presence of (2) an organohy-drogenpolysiloxane fluid having a viscosity of from 10 to 1,000,000 centi-poise at 25°C., in which the organohydrogenpolysiloxane fluid is present in an amount of from 20 to 95 percent by weight based on the weight of mono-mer (1)  and organohydrogenpolysiloxane (2) and (3) a free radical initiator to form a composition having in-situ generated particulate matter dispersed therein and having a polymeric organic group which is constituted of recur-ring units derived from monomer (1) grafted to the organohydrogenpolysiloxane (2).  The composition contains in-situ generated particulate matter.  The particulate matter results from the polymerization of monomer (1) in the presence of organohydrogenpolysiloxane (2) and free radical initiator (3), (b) a vinyl containing compound having at least two vinyl groups per molecule which is capable of crosslinking with (A) and (C) a catalyst capable of pro-moting the addition of silicon-bonded hydrogen groups to silicon-bonded vinyl groups.  A process is also provided for preparing such composition, the process comprising reacting an organohydrogenpolysiloxane with an organic monomer in the presence of a free radical initiator at an elevated tempers-ture.  The resultant composition may be combined with vinyl containing com-pounds having at least two vinyl groups per molecule and a catalyst which promotes addition of SiH groups to vinyl groups to form elastomers.  These organopolysiloxane compositions have improved physical properties, e.g. the mixture is homogeneous, and the composition does not shrink on curing, thus making it essentially suitable for use as molding or potting compositions.
