Abstract: ABSTRACT         An ejection mechanism is described which auto-matically assists in the discharge of completed bales from the bale-forming chamber.  As implemented the ejection mechanism forms a part of a baler which produces generally cylindrical bales in a chamber of fixed size having closed sidewalls adjacent the ends of the bale.  The baling chamber is divided into two parts with one portion being hinge mounted along its front edge to allow its second or rear edge to swing open upwardly to provide a gate through which completed bales can be discharged.  The second portion of the baling chamber contains a bottom conveyor for imparting rotational motion to the bale during the crop gathering and bale forming process.  When the bale in the chamber is com-pleted and ready for discharge, the gate swings open and the bottom conveyor continues moving in a front to rear direc-tion.  Simultaneously with the opening of the gate, bale contacting means are applied at the top edges of the bale to introduce a coupling force which tends to stop the bale from turning in place, thereby enabling the bottom conveyor to transfer the bale out the gate of the machine.

Abstract: ABSTRACT      A closure and sealing device for closing and sealing an open-mouthed vessel having a vessel neck and further having an orifice defined by a vessel neck lip protruding axially and radially from said orifice.  A bottle cap in accordance with the preferred embodiment is designed to prevent the transfer of liquid or gas between the interior of the bottle and the atmosphere and includes two elonga-ted, tapered sealing members disposed around the interior perimeter of the cap with the sealing members angularly disposed such that they diverge from each other.  The tapered ends of the elongated sealing members are adapted to make firm contact against the top and side of the lip.          Seal augmenting means consisting of a relatively massive protruding region disposed around the interior perimeter of the cap below the sealing members are adapted to urge the sealing members into sealing contact with the lip and acts as a third sealing member.  When the closure device is placed over the lip, a depending skirt portion extends down the outside of a vessel neck to cover and seal against a second protruding bottle neck located axially downward from the orifice defining lip and an opening tube depends from the lower portion of the skirt.  One side of the tab leads into an opening groove formed in the exterior of the skirt such that pulling the tab tears the closure device for removing the closure device from the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE    Combined metal-to-metal/compliant material  stem sealing means for high pressure, balanced, rising stem gate valve includes at least one seal set at each of the actuator and bal-ance stems.  Each seal set comprises a pair of frustoconical metal ring gaskets between which are disposed two make-up rings of complaint, tough material of high lubricity, e.g. tetra-fluoroethylene polymer.  One make-up ring is adjacent to one gasket, and the other make up ring is adjacent to the other gasket.  A core ring of material that expands substantially less volumetrically upon heating than the make-up rings, e.g. com-pacted graphite, is disposed between the make-up rings.  Around the inner periphery of the core ring adjacent the respective actuator or balance stem is disposed a bearing ring of material like that used for the make-up rings, e.g. tetrafluoroethylene polymer.  The seal set is compressed by a packing retainer such that the metal gaskets are coined into metal-to-metal sealing engagement with the stems and adjacent valve body parts.  The sandwich stack, consisting of the core ring and bearing ring disposed between the make-up rings, is deformed to conform to the shape of, and fills substantially all of the space between, the compressed metal ring gaskets.  The volume of the core ring is approximately one-third of the total volume of the sandwich stack.

Abstract: ABSTRACT:         In a dynamic amplifier circuit, which can specifically be used in switched capacitor filter cir-cuits, a current source supplies a bias current to the amplifier.  At the beginning of the amplifying period the bias current is high to obtain a high speed of amplifi-cation and at the end of the amplifying period the bias current is small to obtain a high gain and high accuracy.         An undefined value of the bias current at the end of the amplifying period may give rise to incorrect operation of the amplifier circuit.  According to the invention this problem is avoided by including an additional bias cur-rent source which defines the minimum bias current in the amplifier circuit.

Abstract: ABSTRACT         A co-channel communications system is disclosed which permits a digital data signal to be simultaneously transmitted with a communications medium signal such as telephone voice or television video.          The data signal or signals are converted into very low multifrequency signals consisting of fundamental frequencies and harmonics which span the communications bandwidth.  Because a number of frequencies are used for each data signal, the signal level of the data signals can be greatly suppressed relative to the communications medium signal to a level such that there is no perceptible degradation of the telephone voice or television video.  Synchronous detectors for each frequency transmitted, including harmonic frequencies, are utilized to recapture and regenerate the data signals transmitted.

Abstract: ABSTRACT OF THE DISCLOSURE         A disc player, for reproducing program information from a disc on which the information is recorded as digital program information data accompanied by digital address data, comprises an optical reader for reading program information data and address data from the disc, such reader being selectively operable in a searching mode and in a playback mode, processing circuitry supplied with program information data to produce program information from the program information data, a detecting means that compares designated address data identifying desired program information with the reproduced address data in the output of the reader and system controlling means for controlling the reader to continue the searching mode until the reproduced address data match the designated address data, at which time the system controlling means operates the reader in its playback mode to read from the disc the program information data identified by the designated address data.          Noise-suppressing means substantially prevents the processing circuitry from producing program information from the program information data in the output of the reader operating in the searching mode.  The clicking noises and other spurious sounds produced by prior art disc players from the program information data read during the searching mode are thus prevented from occuring before the production of desired program information from the disc.

Abstract: ABSTRACT      A flow meter apparatus for measuring the mass flow rates of fluids passed through two essentially parallel, cantilever mounted U-shaped flow tubes where, instead of the fluid serially passing through one of the U-shaped flow tubes and then through the second U-shaped flow tube, the fluid is essentially evenly divided and half of the fluid is passed through one U-shaped flow tube and the other half of the fluid is passed through the other U-shaped flow tube.  The two U-shaped flow tubes are sinusoidally driven as the tines of a tuning fork, and when a fluid is passed through the oscillating U-shaped flow tubes Coriolis forces are generated which torsionally deflect the U-shaped flow tubes.  Such torsional deflections are a function of the mass flow rate of the fluid passing through the two U-shaped flow tubes.
