Abstract: A method and apparatus utilized in conjunction with a wire galvanizing apparatus assures a bright finish on the coated wire. This method and apparatus includes passing the wire through a water quenching bath immediately following the emergence of wire from the molten zinc galvanizing bath of a conventional galvanizing apparatus. A pair of pressure pads grips the wire at its entrance to the water quenching bath for substantially sealing the water quenching bath against water leakage into the adjacent molten zinc galvanizing bath. A heating apparatus is directed at the wire prior to its entrance to the pressure pads to assure that the zinc coating is still in a molten condition as the wire enters the water quenching bath.

Abstract: A feeder for livestock and the like is disclosed. The feeder has a feed receiver body for receiving and storing a flow of feed from a conveyor. A drop tube means extends from the feed conveyor into the feed receiver body, and includes at least one wall mounted for vertical motion relative to a fixed wall. When the moveable wall is in a raised position, that moveable wall and the fixed wall define a vertically oriented opening through which feed can pass from the drop tube into the receiver body. By adjusting the position of the moveable wall, the amount of feed collected in the receiver can be correspondingly changed. When a stopper valve member is drawn away from a discharge opening, the feed pile collected in the receiver body is discharged from the receiver for livestock consumption. A stopper actuator includes a flexible member connected to the stopper valve, and a rotatable windup device connected to the flexible member.

Abstract: The disclosure relates to a lens case for supporting a pair of contact lenses in a liquid solution to be heated to an elevated temperature for effecting sterilization or disinfecting of the lenses. The lens case includes a generally cylindrical open ended container for housing the liquid, a cap for closing the open end of the container, and a lens holder arrangement for supporting the lenses to be sterilized. The cap includes means for supporting the lens holder and the lenses confined therein emersed within the liquid. Further, said cap includes a circumferential downturned annular flange that forms a recess within the cap to provide an air pocket and an area which provides an expansion chamber for the liquid. More specifically, upon assembly of the cap to a filled container, the air pocket will displace excess liquid from the container as the cap is assembled in place.

Abstract: An ammonium nitrate particle removal apparatus is joined with an exhaust gas flow of a nitrogen oxides abatement system as utilized in a nitric acid producing plant for removing ammonium nitrate particles carried in the gas flow. The apparatus includes a filter element for receiving the gas flow and substantially trapping the ammonium nitrate particles. Injection nozzles inhabit a conduit which delivers the exhaust gas flow to an inlet of the filter and inject a water mist into the gas flow which mist acts to irrigate the filter. As a result of this irrigation, the trapped ammonium nitrate particles go into solution and drop by the action of gravity to a tank or reservoir below the filter element, where the solution may be recovered for other uses as desired.

The back and side support means are arranged to define a confinement boundary for the back and side panels of the bag and have dimensions generally corresponding to the height and width dimensions of the bag when opened. The rack further comprises bag suspending means carried by each side support means arranged to receive the bag handles for maintaining the bag in a suspended, opened condition. A rack mounting means projects rearwardly from the back support means and has pendant coupling means for mounting the rack along the top edge of a horizontally disposed support member.

Abstract: An automatic chord control system is readily incorporated in an electronic organ by means of large scale integrated circuit chips. The automatic chord control causes a chord or group of notes within an octave played on the lower manual keyboard to play through the upper manual voice in the octave below the lowest melody note being played on the upper manual keyboard. The proposed automatic chord control system has two operating modes. In the first mode, the notes transferred to the upper manual are generated in direct correspondence to the keys activated on the lower manual. In the second mode, the notes transferred to the upper manual are generated by a set of preset chords activated by single lower manual keys.

Abstract: An apparatus and method are disclosed for inducing pitch stability in musical strings. A tensioned string is placed in a frictioning channel provided in the apparatus; and the apparatus is then caused to traverse the length of the string repeatedly to maximize the string elongation and tensional stability.

Abstract: An electronic organ or the like is provided with a plurality of frequency generators greatly less than the number of keys on the organ. Each generator is capable of producing an electrical oscillation of proper frequency for any musical note on the organ keyboard. The frequency generators are assigned to the desired frequency called for by depression of any key. Pulses are dropped, preferably in different numbers, from the frequency generators to avoid locking of oscillators in any musically desirable relationship to one another, including octave or harmonic relation.

Abstract: There is disclosed a transcutaneous electrode construction for the application of electrical pulses to a patient, such as might be employed in pain therapy. The electrode construction includes a base member comprising a sheet of nonconductive material having an adhesive coating on one surface. A thin liquid impervious nonconductive sheet of smaller surface area than the base member is centrally affixed thereto on the adhesive coated surface so as to be entirely surrounded by the adhesive coating. A sponge pad overlies the liquid impervious sheet and has a larger surface area than the liquid impervious sheet so that its peripheral edges engage and adhere to the adhesive of the base member while leaving sufficient adhesive surface exposed for adhering to the skin of the patient. Due to the fact that the sponge pad is adhered to the base member only about the edges thereof, a chamber or pocket is formed between the sponge pad and the impervious sheet for receiving a quantity of electrolytic gel.

Abstract: A voltage regulator and brush assembly for an alternator has a body of the voltage regulator mounted on a housing of the brush assembly. A screw passes through an apertured flange at one end of the body of the voltage regulator and engages in a screw threaded hole in a recessed surface on the housing of the brush assembly. At the other end of the body of the voltage regulator there are provided two tongues which define a slot having an inwardly tapering free end. A recess facing the fixing screw is provided in the brush housing and the tongues engage in the recess so that the slot between the tongues abuts against a correspondingly shaped shoulder in the recess whereby when the screw is tightened the tongues engage in the recess with a wedging action which provides a firm, vibration-free connection between the voltage regulator and the brush housing.

Abstract: A thread-forming screw has a point or lead thread portion having a relatively steep entry angle with respect to the screw axis. Adjacent to the point thread is a tapered thread portion of about two to three pitches in axial length. This tapered thread has a shallow entry angle defined by the taper of the maximum diameter of the thread toward the point. This shallow entry angle may be approximately 5.degree. to 8.degree. or equal to about three times the helix angle of the tapered thread. This configuration of the tapered thread results in a balanced action of thread formation and axial in-feed of the screw, resulting in a lower end pressure to initiate the thread-forming in a workpiece. A roll-threading die is contoured to provide ridges and valleys to effect the tapered thread portion.

Abstract: A pivotal mounting arrangement, which may be used for mounting a lamp on a vehicle body, comprises a plastics body having an integral boss provided with a hexagonal inwardly tapering recess therein. A socket element formed from a spring steel sheet has a cup-shaped central portion and six arms extending integrally upwardly therefrom. Outwardly projecting portions extend from the arm and the distance between opposed portions is greater than the corresponding dimension of the recess. A ball integral with one end of a screw-threaded rod is engaged in the socket element before the latter is forced fully into the recess. When disposed in position in the recess, the arms of the socket element are deformed inwardly and hold the ball captive while allowing same to rotate relative to the socket element.This arrangement permits the boss to be formed out of a material which can be relatively rigid because the boss itself need not be resilient.

Abstract: A semiconductor device is surface-passivated by a multi-layer film which includes a base coat of substantially undoped polycrystalline silicon in intimate contact with the substrate and bridging the semiconductor junction. A top coat of polycrystalline silicon is doped with oxygen and disposed overlying the base coat.The method of passivating a semiconductor device includes initial formation of a base layer of substantially undoped polycrystalline silicon from a controlled atmosphere of a silane material. This is advantageously followed by a deposition of oxygen-doped polycrystalline silicon in continuation of the atmosphere of silane material with the added introduction of a gaseous oxygen donor.

Abstract: There is disclosed a door frame construction, preferably of metal, which comprises cross channel members assembled perpendicularly with a pair of parallel upright channel members to form a rectangular frame. The respective channel members are held in assembled squared relation by a novel type of joint construction, which joint includes a pair of elongate slots formed in ones of the channel members which slots cooperating receive first detent members formed on the other of the channel members. The first detent members prevent disassembly of the joined channel member in a generally lateral direction. In addition, said slot also cooperates with second detent members received therein, which preclude relative pivotal movement between the assembled channel members and thereby serve to maintain the channel members in squared relation.

Abstract: An analysis instrument for measuring selected constituents present in a sample of a material such as a bulk commodity includes a test cell to receive the sample. The test cell comprises a capacitor whose electrical properties are modified in accordance with the dielectric constant of the sample, which dielectric constant is a function of the contents of the sample. Weight and temperature sensors are provided for producing signals corresponding to the weight and temperature of the sample in the test cell. An electronic measuring circuit is connected to a test circuit including the test cell capacitor and to the weight and temperature sensors for producing an indication of the contents of the sample. The measuring circuit produces the indication by correcting a measurement taken across the test cell in accordance with the variation in the temperature of the sample from a reference temperature and the variation in the bulk density of the sample from a reference bulk density.
