Abstract: WALL CONTACTING TOOL          Abstract of Disclosure:         A wall contacting tool, such as a fixed blade rotating stabilizer, useful in earth boring has replaceable wear pads.  Each pad is of generally sector shape cross section, the pad corner having a 90° apex angle and fitting in a correlative V groove flute at the end of an arm of the stabilizer body, being held in place by radial dowel pins each bisecting the apex angle of the corner and flute.  Each pin has a head turned to be retained in a slot in the body and having a threaded socket receiving a cap screw whose head engages an outwardly facing shoulder in a stepped hole in the pad.  The pad corner above and below the dowel pin locks the dowel pin head against turning.  A releasable retainer ring in an annular groove in the stepped hole prevents withdrawal of the cap screw from the pad.  A lateral dowel in between one side of the pad corner and one side of the body flute pre-vents movement of the pad radially outwardly from the flute.

Abstract: BALL NUT TYPE STEERING GEAR            ABSTRACT OF THE DISCLOSURE     In a ball nut type steering gear for a motor vehicle having two trains of balls confined within passageways formed by the helical grooves in a threaded shaft and a ball nut which surrounds the threaded shaft, two major diameter portions disposed in spaced-apart relation are formed in the threaded shaft.  When the motor vehicle travels straight ahead, the balls are rollingly engaged in the helical grooves in the major diameter portions of the threaded shaft and the ball nut, and there is no play between the grooves and the balls which are engaged in the grooves.  However, when the steering wheel is manipulated, the balls are rollingly engaged in the helical grooves in portions of the threaded shaft which are smaller in diameter than the major diameter portions of the threaded shaft, and there is play of a certain extent between the balls and the helical grooves.

Abstract: ABSTRACT An apparatus is disclosed which is mountable in a strapping machine frame adjacent a strap chute and adjacent a strap end gripping and sealing assembly.  The apparatus has a pivotably mounted strap guide arm and gripper for guiding the strap during feeding in a first, upper position and for gripping the strap when the arm moves downwardly away from the first position.  The strap is both fed into the strap chute and subsequently pre-tensioned by a pair of coacting feedwheels.  A high tension pinion gear is mounted for rotation on an axis which is fixed relative to, and movable with, the strap guide arm.  The pinion gear engages a rack member which is secured on one end to the strapping machine frame and which transmits the reaction force from the pinion gear to the strapping machine frame when the pinion gear is rotated in engagement with the rack.  A single, reversible, rotating drive motor is mounted for movement with the guide arm and powers a gear drive assembly which is engaged with the motor and movable therewith for (1) rotating the feedwheels to feed the strap when the motor is rotating in a first direction, (2) rotating the feedwheels to withdraw the strap to pretension the loop with a first predetermined tension when the motor is rotating in a second direction, and (3) rotating the high tension pinion gear when both (a) the motor is rotating in the second direction and (b) the tension in the strap exceeds the predetermined, first tension.  During high tensioning, the pinion gear moves along the rack and pivots the guide arm out of the first position to a second position whereby the gripper is actuated to grip the trailing portion of the strap and pull the gripped strap, thereby drawing a higher, second tension in the loop.

Abstract: ABSTRACT OF THE INVENTION      A poultry raising system includes a house having one or more enclosed sections with at least one section provided with a plurality of hovers and all of the sections having peripheral heat assemblies.  All hovers and heat assemblies are equipped with sealed heat radiating conduits supplied with a fluid heat transfer medium from a common heating apparatus. A supply and return line serving each section from the heating apparatus includes a thermostatically-controlled valve admitting the heat transfer medium to all of a section's hovers as well as other thermostatically controlled valves regulating the flow of heat transfer medium to each of a section's peripheral heat assemblies.  Dampers in roof-top vents are automatically opened and closed in response to signals from a gas sensor in each section to evacuate obnoxious gases from each section enclosure and the evacuated gas is replaced by fresh outside air admitted through automatic dampers adjacent the house side walls.  Im-proved efficiency is obtained by employing a pair of heating chambers in the heating apparatus and by extracting otherwise lost heat from waste flue gases to pre-heat air for combustion in the heating chambers.

Abstract: Abstract A teller machine which includes a dispenser for dispensing banknotes or other items for delivery to a customer in accordance with a customer-requested transaction, is switchable between a first, teller-assist mode in which the dispenser dispenses items under human control exercised from a teller's station, and a second, automated mode in which the dispenser dispenses under programmed control in accordance with customer requests entered into the machine from a customer's station.  The two stations are located close to one another, in particular opposite across a counter-top, and the dispenser dispenses to a position that is within reach from both stations, in particular into a pan sunk into a counter-top between them, whereby delivery to the customer of dispensed items when the machine is operating in its first mode is within the personal influence of the human teller in the provision of personal service to customers while the teller's station is manned.

Abstract: ABSTRACT           The invention relates to an apparatus for the treatment of molten metal with a reactive additive.          The apparatus comprises a pouring cup having an outlet for introduction of both reactive additive and molten metal into a reaction chamber. The reaction chamber communicates via a channel, preferably of restricted cross-sectional area, with an expansion chamber provided with an outlet for the molten metal.  The expansion chamber outlet has a smaller cross-sectional area than the pouring cup outlet thereby ensuring that the reaction chamber is sufficiently filled to cover any reactive additive during a pouring treatment.  The apparatus permits a series of pourings to be effected without disassembley of the apparatus to introduce more reactive additive.

Abstract: METHOD FOR FORMING A NARROW DIMENSIONED      MASK OPENING ON A SILICON BODY                           Abstract A method for forming a narrow, such as a submicrometer, dimensioned mask opening on a silicon body involving forming a first insulator region having substantially a horizontal surface and a substantially vertical surface.  A second insulator is applied on both the the horizontal surface and substantially vertical surfaces.  The second insulator is composed of a material different from that of the first insulator layer.  Reactive ion etching of the second layer removes the horizontal layer and provides a narrow dimensioned second insulator region on the silicon body.  The surface of the silicon body is then thermally oxidized.  The narrow dimensioned second insulator region is removed to form a narrow dimensioned mask opening.

Abstract: ABSTRACT OF THE DISCLOSURE A printed circuit board with electronic compo-nents wired thereto has a conformal insulating coating consisting of a single component of essentially pure urethane formulation and a minor amount of fumed colloi-dal silica powder.  The insulating coating covers as-perities and protrusions as well as the conductors and circuit components while maintaining a transparent characteristic.  The coating material is made by mixing of the small proportion of silica with essentially pure urethane formulation under controlled conditions to pre-vent moisture contamination of the materials.  The mix-ture is thoroughly mixed, deserted under reduced pres-sure with a pulsating pressure to break any air bubbles and remove essentially all air.  The coating is applied in an environment having at least 30 percent relative humidity and within a confined area defined by an encir-cling dam masking compound.  The coating is allowed to partially cure at room temperature and the confining dam compound removed.  For maximum protection, a further period  of curing of one week is provided.
