Abstract: PEDAL TEACHING AID FOR AN ELECTRONIC           MUSICAL INSTRUMENT                          ABSTRACT         A pedal teaching system for an electronic musical instrument, specifically an electronic organ.  In the rehearse mode of operation the system rhythmically energizes selected ones of a plurality of lights mounted above the pedal clavier to illustrate which pedals form a bass note accompaniment routine for a specific group of keys depressed by the organist and automatically sounds the bass note routine.  In the perform mode of operation the system rhythmically energizes selected ones of the plurality of lights to illustrate which pedals form the bass note accompani-ment routine and disables the automatic bass note musical output routine so that the organist must physically depress the actual pedals to provide the bass note accompaniment.  In a non-rhythmic or static rehearse mode of operation the system illuminates the root bass pedal light corresponding to the chord played on the organ or the bass pedal light corresponding to the lowest frequency being depressed on the organ; and, automatically sounds the appropriate bass note.  In a non-rhythmic or static perform mode the system only illuminates the appropriate pedal light.

Abstract: MACHINE FOR FORMING CYLINDRICAL HAY BALES              Abstract of the Disclosure A machine for forming large round bales of hay and the like has a pickup mechanism that removes the crop from the field and delivers it rearwardly between a pair of compresser rolls, which deliver crop material in a mat to a baling zone between upper and lower endless conveyors.  The upper conveyor includes a plurality of endless belts trained around a plurality of transverse rollers, one of which is disposed adjacent the rearward end of the lower conveyor and is mounted on a rear gate assembly that is swingable upward and rearwardly to permit discharge of the bale from the baling chamber.  As the bale increases in size, its center of gravity moves rearwardly and after its initial stage of forma-tion, it is partially supported on the roller adjacent the lower conveyor, said roller being disposed generally below the center of the bale when the bale reaches full size.  An auxiliary roller is provided on the rear gate assembly immediately adjacent to said main bale support roller to help support the underside of the bale and thereby reduce the penetration of the roller into the periphery of the bale, the auxiliary supporting roller being vertically adjustable relative to the main support roller to selectively vary the amount of load carried by the main support roller and thereby selectively vary the rolling resistance caused by the penetration of the main support roller into the bale periphery.

Abstract: ABSTRACT OF THE DISCLOSURE         A child-resistant locking means for a container has a threaded neck and a closure therefor.  The closure has an inner threaded skirt and an outer more flexible skirt on the lower mar-gin of which there is at least one axially extending, depending lug.  The container has an abutment near, but spaced radially from, the base of the neck.  The abutment has a face that lies in a radial plane of the container and an outer surface that ex-tends inwardly from the outer edge of the abutment face angular-ly across the normal circular path of the closure lug.  When the closure is turned onto the container neck, the lug (1) engages the outer surface of the abutment and is flexed outwardly there-by, (2)  snaps inwardly after it is turned beyond the abutment and (3)  engages the radial face of the abutment when the closure is turned in a retrograde direction.  In order to remove the closure, the outer skirt and the tab manually are squeezed in-wardly so as to pass the abutment.

Abstract: ABSTRACT      A hydraulic vibration brake for use in nuclear power plants is shown.  The brake has a casing that a piston divides into two chambers.  A storage tank in hydraulic fluid communication through appropriate conduits and valves maintains proper pressure in the system.  The piston rod penetrates the casing wall and, at this penetration has a seal which arrests fluid leakage.  In this manner, no hydraulic fluid is lost at the seals and sufficient fluid always is available to enable the brake to carry out its function, thereby eliminating the need for a number of burdensome in-spections.

Abstract: THRUSTERS FOR AIRSHIP CONTROL            Abstract of the Disclosure The use of thrusters at the bow and stern of an air-ship for control of the direction, attitude, and orientation of such an airship is described.  The thruster utilizes an electric motor or a gas turbine for power.  In the electric motor embodiment, the motor utilizes two contra-rotating rotors which each drive a separate and contra-rotating pro-peller to generate the controlling jet of air.  Thrusters are arranged in pairs at the top, bottom, and each side of the bow and stern of the airship.  Lifting thrusters direct-ed downwardly and located above the longitudinal extent of the hull are provided to augment the static lift capability of the airship when under heavy load.

Abstract: ABSTRACT           An air outlet for the admission of conditioned air to rooms and other inhabited spaces includes an air box with an air outlet slot.  The air outlet slot is longitudinally subdivided to form individual ducts each of which contains an independently adjustable air guide vane.  Internally, the outlet slot may be variably obturated by three superimposed control slides, each of which has periodically occurring covering surfaces, the width of which corresponds to the width of an air outlet duct.  The covering surfaces on each control slide are disposed at a distance corresponding to four duct widths.  The air box contains thermostatically controlled actuators which are coupled to the control slides in such a way as to permit their relative longitudinal, i.e., axial, displacement when a first control slide is moved between positions corresponding, respectively, the second and/or third control slides are partially carried along so as to define configurations resulting in a variation of the volumetric air flow but maintaining the speed of the emerging air constant.

Abstract: ABSTRACT OF THE DISCLOSURE A deposition process is described wherein a deposit-able vapor, typically chromium, from a vapor source is provided in a vacuum in a chamber which also contains a substrate. The vapor, which normally deposits in tension, is permitted to contact the substrate to cause a deposit thereon.  The deposit is bombarded with accelerated particles comprising energetic atomic particles from another source so that the internal stress of the deposit is about zero or in compression. This action favorably modifies the deposit, for example, in the case of chromium, an increase in reflectance is obtained. Only relatively few energetic particles are required to bring about desired change.

Abstract: ABSTRACT     A very low concentration (below 0.03 M) trivalent chromium plating bath in which the source of chromium is an equilibrated aqueous solution of a chromium (III) - thiocyanate complex gives a deposit of unexpectedly light colour.  Such a bath is employed to produce thin overcoatings of light coloured chromium for decorative applications. The bath and process is also used to plate the initial layer of a thick (greater than 5 micron) deposit for engineering applications, the major part of which is plated from a higher chromium concentration bath. Such thick deposits from a higher concentration bath are more cohesive and smoother when plated over an initial layer from the low concentration bath.

Abstract: Abstract A  melter  needle  position control  mechanism  and  motorized incremental drive is disclosed for controlling the position of a needle relative  to  an  orifice  in  a  furnace.   Conventional  melter needle control mechanisms  are cumbersome,  inaccurate and do not facilitate servicing of the needle.  The present mechanism has a support 36 for a fluid  operated  piston  49  which  allows  a boom or I-beam  76  to be rotatably mounted and to extend over the orifice 32 of a melter 10. A movable mount 144, providing a support for a needle 30, is vertically translated by a vertical adjustment shaft 184 that is driven by a miter gear 156.  The gear 156 is coupled to a rotatable command shaft 164 which is controllably rotated by a motorized incremental drive 26. A rotary  actuator  67  rotates  the  I-beam  76  and  the needle  30  to  a retracted position after the I-beam 76 is sufficiently moved vertically whereby the needle 30 may be serviced.   Radial,  lateral and initial vertical adjustments are possible with the present invention.
