Title: Continuous round baler and method
Inventor: FELL FEROL S
IPC: A01F15/07
Filed: 1986-11-26
Granted: 1991-11-19
Abstract: CONTINUOUS ROUND BALER AND METHOD            Abstract of the Disclosure The baler has a "vertical" bale starting chamber in which the upwardly moving rear belts and the downwardly moving front belts cooperate to tumble and roll incoming material into a bale. When the bale reaches full size in the expanded chamber, the bale is lifted to a wrapping station where it continues to spin as a binding wrapper is applied,  During the lifting of the finished bale and subsequent application of the wrapper, fresh material entering the continuously moving baler is confined beneath the finished bale in a new start-ing chamber, whereupon the cycle is repeated.  As the new bale grows,  a discharge ramp becomes formed by certain stretches of the belts and rollers to gravitationally discharge the wrapped bale from the baler without stopping advancement of the machine.

Title: Polyurethane elastomers prepared in a two-step process using mixtures of chain extenders
Inventor: PEFFLEY RICHARD D
IPC: C08G18/65
Filed: 1986-11-27
Granted: 1994-12-06
Abstract: This invention relates to a process for pre-paring polyurethane and/or polyurea elastomer compris-ing reacting a liquid preformed isocyanate-terminated prepolymer with a chain extender mixture, which chain extender mixture comprises (a) a mixture comprising a hydroxyl-terminated chain extender and an aromatic amine-terminated chain extender, and/or an aliphatic amine-terminated compound, or (b) a mixture comprising an aromatic amine-terminated chain extender and an aliphatic amine-terminated compound, wherein the isocyanate index is from 70 to 200.           The prepolymer is the reaction product of a stoichiometric excess of a polyisocyanate and a relatively high equivalent weight isocyanate-reactive compound.     In this process, it is possible to prepare elastomers having excellent properties, particularly excellent flexural and thermal properties, which prop-erties are difficult to obtain in a one-step process. The reactivity of the chain extender mixture with the prepolymer is such that this process is easily carried out, making it possible to mix the reactants and fill the mold before gelling occurs, yet providing an elas-tomer which has good green strength at demold.

Abstract: ABSTRACT            The present invention briefly concerns a device for connecting individual pipes (22, 23) to pipe lines, which device includes a male part (24) and a female part in a direct connection to each pipe (22,  23),  the pipes having a substantially complementary design to fit into each other. The male part (24) comprises an outwardly conical portion (26) having a decreasing diameter towards the adjacent end (28) of the pipe (23), and the female part (30) comprises an inwardly conical portion having an increasing diameter towards the pipe end.          Both conical portions are provided with a circumferentially extending groove (29, 33) respectively, which, when the male part (24) is inserted to a predetermined position in the female part (30), are opposite of each other forming a canal for receiving a lock thread (34). A hole for insertion of the lock thread (34) into this canal is made through the wall of the female part (30). A seal ring (31) is provided in the area between the lock grooves (29, 33) and the free end (28) of the female part (24).     (Fig. 4)

Title: Deadbolt assembly
Inventor: NEWMAN DONALD J
IPC: E05B63/12
Filed: 1986-12-17
Granted: 1992-04-21
Abstract: ABSTRACT                 "DEADBOLT ASSEMBLY"       A deadbolt assembly of the kind in which a deadbolt is mounted on a housing for linear movement between inoperative and inoperative positions in which the deadbolt engages with and does not engage respectively,  a strike.  An actuator is rotatably mounted on the housing and is drivably connected to the actuator through a drive plate which rotates in response to operation of the actuator, and a drive pin is secured to the plate at a position radially outwards of the rotational axis of the plate.  The pin locates within a non-circular hole provided in the deadbolt and reacts against edges of that hole to  cause  the  deadbolt  movement.   The  pin  moves  along  an arcuate path between each of its two extreme positions, and at each of those positions the pin lies on a straight line which extends substantially parallel to the direction of movement of the deadbolt and which substantially intersects the rotational axis of the drive plate.  Both the deadbolt and the strike can be made from steel or other strong metal.

Abstract: ABSTRACT OF THE DISCLOSURE             A section of a vein to be used for example in aorto-coronary bypass surgery, is harvested by making two incisions severing the vein at opposite ends of the section to be removed.  A plastic guide is inserted in one incision, passed through the length of the vein section and out the other incision.  A plastic tube having an inside diameter slightly larger than the outside diameter of the vein to be harvested and having two knife blades at its leading end is inserted into one of the incisions and slipped over the end of the vein section to be removed.  The tube is pushed in over the vein section, while rotating the tube to sever vein branches by the knife blades and heating the knife blades electrically to cauterize ends of the severed branches, until the leading end of the tube reaches the other incision.  The tube is then withdrawn with the vein section inside it.

Abstract: FRAUD PREVENTION IN A PUBLIC TELEPHONE STATION            Abstract Control equipment employed in a customer-owned public telephone station prevents a user from making unauthorized telephone calls in the telephone system. Operating under the control of a computer in the station, the control equipment is responsive to momentary loop breaks occurring on tip and ring lines connecting the station to a central office, and to a loop break provided by the central office which reflects that the far end party has disconnected. The control equipment is also responsive to scheduled as well as unscheduled receipt of dial tone. The combination of ongoing loop break and dial tone detection and analysis conveniently provides the desired protection for reliable operation of the customer-owned public telephone station in the telephone system. Restrictions incorporated in the station for obtaining the desired protection are applied with minimal inconvenience for the legitimate user.

Granted: 1992-09-29
Abstract: ELECTRONIC BATH SCALE Abstract of the Disclosure A bathroom platform scale is disclosed having a reinforced plastic base and platform.  The platform is carried by a pair of triangular-shaped actuation levers which directly engage a single transducer, such as a strain gauge, centrally located in the base, to sense the weight on the platform.  Such an arrange-ment allows for a relatively compact scale.  The tri-angular-shaped levers are supported by knife edge bearings which define a fulcrum.  An integrally formed tongue extending from an apex from each of the tri-angular-shaped levers applies the weight distributed on the platform to the transducer.  The triangular-shaped actuation levers are also self-aligning, thus facilitating assembly of the scale.

Title: Surround-sound system

IPC: H04S5/00
Filed: 1989-01-05
Granted: 1992-12-01
Abstract: Abstract of the Disclosure Spectral imbalance (alteration in timbre) when playing home video versions of motion pictures is overcome by re-equalization according to a unique correction response curve which compensates for the equalization for playback in large theater-sized auditoriums inherent in motion picture soundtracks.          Surround-sound home playback of motion pictures is enhanced by employing main channel loudspeakers that produce generally direct sound fields and surround channel loudspeakers that produce generally diffuse sound fields.  Preferably, further equalization is applied to the reproduced surround channel to compensate for the differences in perceived timbre between direct and diffuse sound fields.  In addition, the reproduced surround-sound channel is further enhanced by decreasing the interaural cross-correlation of the surround-sound channel sound field at listening positions within the room, preferably by introducing slight pitch shifting in the signals applied to multiple surround loudspeakers.
