Abstract: ABSTRACT        A digital tuning system for use in radio frequency multi-signal receiving systems, e.g., a CATV converter, utilizes a closed feedback loop digital arrangement for channel selection (local oscillator frequency con-trol) and channel fine tuning.  More particularly, the system includes an oscillator responsive to a variable control voltage for generating an oscillation having a frequency dependent on the magnitude of the control voltage.  A sampler samples the actual output frequency of the oscillator for a predetermined interval of time and generates a first digital word representing the actual value of the frequency.  A selected one of plurality of address words is generated m response to incoming channel information. Each address word represents a particular operating channel in a CATV sys-tem.  A memory stores various second digital words, each of the second digital words representing any desired frequency of oscillation for the oscillator.  One of the second digital words is retrieved from the memory in response to the address words, the particular location of the second digital word within the memory being identified by the address word repre-senting a particular operating channel in the CATV system.  The second digital word retrieved from the memory is stored and a comparator compares the values of the first digital word and the value of the stored second digital word.  The control voltage of the oscillator is varied in response to a difference in value between the first digital word and the stored second digital word determined by the comparator.  In this way, the actual frequency value is changed to the desired frequency value.

Abstract: Abstract of the Disclosure:         A four-speed planetary transmission has three friction clutches which are selectively engageable in pairs or simultaneously to provide a drive connection between the transmission input and the planetary gearing during the four forward speeds.  One apply piston selectively engages two of the friction clutches and a second apply piston selectively engages the other friction clutch and one of the two friction clutches.  Simultaneous actuation of both apply pistons causes engagement of all three clutches.  A one-way clutch is dis-posed in series drive relation with the friction clutch that is selectively engageable by both apply pistons.

Abstract: HARVESTER HEADER WITH TRANSVERSELY  INCLINED, OVERLAPPING CONVEYORS                     Abstract of the Disclosure . .    .     A multirow harvester header comprising a plurality of pairs of crop conveyors.  Each conveyor pair corresponds to a single row of crop and is used to converge and convey a single row from a standing position in the field into the crop receiving throat of the harvester attached to the rear of the header.  A first and second pair of the conveyors is inclined transversely and down-wardly in a direction toward a third and fourth pair of the conveyors.  The third and fourth pair of conveyors are inclined transversely and downwardly in the direction of the first and second pair of conveyors.  The second and third pair of conveyors are vertically spaced above and in overlapping relationship respectively with the first and fourth pair of conveyors.  The transverse inclination and overlapping relationship of the convey-ors enables the rear drive shafts of each pair of conveyors to be closely spaced together in front of the crop receiving throat of the harvester.  The transverse inclination also enables the forward ends of the conveyors and associated crop cutters to be positioned at an equal distance above the ground and in a trans-verse vertical plane at the forward end of the header.  Additional space adjacent the harvester throat is saved by driving two of the conveyors of the first and second pair of conveyors from a common rear drive shaft and by driving two of the conveyors of the third and fourth pair of conveyors from a common drive shaft.  Sealed gear cases are provided for the conveyor drive means.

Abstract: COATING OF SEMICONDUCTOR WAFERS AND APPARATUS THEREFOR   Abstract of the Disclosure In the production of coatings on semiconductor wafers, fragile equipment is used and also difficulties in obtaining uniform coatings arise.  The invention provides a form of boat for holding wafers and a manifold structure for feeding gases to the boats, and wafers which are less fragile cheaper and easier to manufacture and give more uniform coatings.  The boats are relatively short, of semi-cylindrical form with slots through which gas can flow, and with rails for positioning and holding wafers at correct heights.  The manifolds have apertures which are spaced at varying distances along the manifold as compared to the conventional longitudinal slot.  The invention is particularly applicable to producing oxide coatings and polycrystalline silicon coatings on silicon wafers.

Abstract: ABSTRACT     The invention relates to improvements in a diver's semi-closed circuit breathing apparatus and is intended to better control the partial pressure of oxygen during descent and ascent.  Such apparatus includes a counterlung, sources of oxygen and inert gas, an oxygen regulator, a mass flow jet in the oxygen circuit, a regulator for the inert gas, and a feed-back controlled laminar flow element for feeding a mix-ture of the oxygen and inert gas to a counterlung of the breathing apparatus.  The improvement comprises the provision of an oxygen accumulator in the oxygen circuit following the mass flow jet so that a portion of the delivered oxygen is diverted thereto during descent to counteract oxygen partial pressure overshoot.  At constant depth the apparatus operates normally, maintaining appropriate oxygen partial pressure, and, during ascent, oxygen is returned from the accumulator to the breathing apparatus to counteract any drop in oxygen partial pressure.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved friction stabilizer for installation in one bore of a plurality of axially aligned bores of diverse, predetermined cross-sectional dimensions which are formed in a structure such as a roof or side wall of a mine shaft or other underground opening, for anchoring the stabilizer in the bore to stabilize the roof or side wall structure therealong.  The stabilizer comprises an elongate body having a wall with an outer surface for frictionally engaging the inner surface of the said one bore.  The body also has a bore-entry leading end and a trailing end and a greatest cross-sectional dimension throughout a principal length thereof, from at least a location adjacent to the trailing end toward the leading end, which is greater than the predetermined dimension of the said one bore to require a substantial insertion force to effect installation of the body into the said one bore.  The wall of the elongated body having the outer surface for frictional engagement also has a thick-ness, configuration, and material composition which are responsive to forces applied to and along the said wall by the inner surface of the said one bore, upon the stabilizer having been forceably inserted thereinto, to cause a frictional engagement of the said wall with the inner surface of the said one bore substantially along the full length thereof.  The improvement comprises a hard metal threaded fastener made integral with the body for receivably attaching thereto, and suspending there-from, an  elongate pendant for fixing an ancillary article, such as a roof plate, to the pendant to effect remote suspension of the article relative to the body, and to support and stabilize the bored structure.

Abstract: Abstract of Disclosure A pump for bottles, cans, containers, and the like, which dispenses a fluid mist or spray.  The pump has a spray head with a series of cavities forming passageways leading from a tube, which extends down into the bottle, can or other container to a jet-orifice at a spray-dispensing nozzle. Between two of the cavities is a trigger-bulb which expands, after compression, under the force of a plastic memory to suck fluid from the can or bottle.  When the trigger-bulb is again squeezed, or otherwise actuated, the fluid is forced out the jet-orifice at the nozzle.  The upper edge walls of the trigger-bulb provide the valving action which opens or closes the passageways to control the direction of fluid flow.  The breathing air which replaces dispensed fluid in the container, or the like, is controlled by a valve action under the flange. To control the amount of fluid which is dispensed on each pump action, the internal volume of the trigger-bulb may be changed by a molding insert or sleeve in order to reduce its volume.  A back-stop anvil limits the rearward travel of the trigger-bulb. In some embodiments, this anvil has a contour which establishes the deformation of the bulb, when it is squeezed.
