Patent NO-177811-C (NO)
Inventor: BENEST ROGER SIDNEY
IPC: A01M7/00
Filed: 1994-02-02
Abstract: A dropleg row crop sprayer (12) senses boom height and tilt from ground-contacting droplegs (46) signalling through potentiometers (74, 76) to a boom control mechanism (84). The droplegs follow crop row wandering through a driven carriage (44). Dropleg attitude is assisted by a cam control system (94, 96). The boom (20, 21) floats through a spring suspension system (128, 138) and is damped by frictional abutment of the boom portions (20, 21), thereby permitting a single actuator (106) to control attitude. A lost motion linkage (126) protects the actuator (106) from snatch loads. Spray control is effected by use of microdroplets discharged from the droplegs (46) below the row crop leaf canopy which protects the droplets from wind turbulence, while electrostatic charges and droplet-energising air flow act to assit crop coating. Where conventional spray droplets are used, the spray direction is fore/aft of the row to minimize ground speed effects. <IMAGE>

Title: Phase controlled synchronization for direct sequence spread-spectrum communication systems
Inventor: RICHLEY EDWARD A
IPC: H04B1/7075
Filed: 1991-05-07
Granted: 1995-08-01
Abstract: A receiver for a direct sequence spread-spectrum communication system of the type in which a transmitter mixes a clocked pseudo-random sequence with a modulated carrier for spreading the carrier energy across a wide band of frequencies, comprises a resident clock-driven pseudo-random code generator for locally generating an essentially identical, spectrum despreading code sequence; means for clocking the resident code generator at a nominal frequency which is offset in a predetermined sense from the clock frequency of the transmitted code sequence such that the phase of the locally generated code sequence tends to slide in one direction with respect to the phase of the transmitted code sequence; detection means for determining whether the the locally generated and the transmitted code sequence are phase aligned or misaligned and for sensing their actual, incipient and/or predicted departures from a phase aligned state, and phase control means for adjusting the clock frequency for the resident code generator whenever such a departure is sensed, thereby shifting the phase of the locally generated code sequencein the opposite direction with respect to the transmitted code sequence by an amount which tends to restore the two code sequences to a phase aligned state. In other words, in keeping with this invention, the receiver has a sliding correlator for phase correlating its locally generated code sequence with the transmitted code sequence at the outset of each incoming transmission, together with a phase controller for regulating the rate at which its resident code generator is clocked once such phase correlation has been achieved, whereby the resident code generator of the phase correlated receiver is clocked at substantially the same average frequency as the transmitted code sequence for the balance of the transmission.

Title: Method and machine for wrapping the side face and one end face of a load
Inventor: MARTIN-COCHER JEAN PAUL CHARLE
IPC: B65B11/02
Filed: 1991-07-15
Granted: 1997-09-30
Abstract: A method is proposed for wrapping a load, delimited by a side face closed upon itself and two end faces, by means of a film of plastic material. In particular,  an initial end part of a strip of film coming from a film reel is associated with the side face of the load.  A relative pivoting movement of the film reel axis and of the load is made about a  first pivoting  axis whose  general  direction  is parallel to the side face, and the strip of film is progressively deposited on this side face.  Film is deposited on at least one end face which is to be covered.  The strip of film is cut and its terminal end part is secured to the deposited film or to the load, wherein the film coming from the film reel is deposited on the end face which is to be covered, and for this purpose  at  least one pass  is made. During  this pass,  a relative pivoting movement of the film reel axis and of the load is made about a second pivoting axis whose general direction is at right angles to the first pivoting axis and to the film reel axis.   The film reel is brought into a general position close to the end face which is to be  covered,  or  in  alignment  therewith.   In  this position,  the relative pivoting movement about the first pivoting axis  is made.  The invention also proposes a machine for wrapping a load by way of film of plastic material.
