Title: Decsion-directed carrier frequency detector and method for qam
Inventor: BOURDEAU RICHARD
IPC: H04L27/38
Filed: 2000-06-30
Abstract: A decision directed frequency detector and method for a quadrature amplitude modulated signal (QAM) demodulator. The demodulator interacts with a voltage controlled oscillator (VCO) that generates a carrier signal to demodulate the QAM signal into a baseband signal. The frequency detector determines the direction of rotation of the baseband signal by sampling the baseband signal relative to predetermined points in the phase plane. For example, if one sample has a negative phase offset with respect to a predetermined point and the next one has a positive phase offset, it detects that the rotation is clockwise, and vice-versa. A control signal is supplied to the VCO and the frequency of the carrier signal is adjusted to stop the rotation of the baseband signal.

Title: Stuffing box for a valve
Inventor: GONSIOR WOLFGANG
IPC: F16K49/00
Filed: 2001-04-06
Abstract: The invention relates to a valve that contains a piston (2) linked with the valve body (8) and received in a housing (4), and a stuffing box (14) interposed between the piston (2) and the housing (4). The stuffing boxes of valves used for media having a high melting point and being operated close to the melting point risk being damaged by so-called freezing medium due to the adhesive properties of the medium in temperature ranges below the melting point. The aim of the invention is therefore to improve such a valve with few constructive efforts in such a manner that the material of the stuffing box reliably works in the liquid range of the medium. To this end, the housing (4) is provided with a heating device (16) in the area of the stuffing box (14). The axial length of said heating device is larger than the axial length of the stuffing  box (14), and the heating device (16) axially protrudes beyond an axial end (22) of the stuffing box (14) by a predetermined length (24, 28).

Title: Method and device for interrow antierosional treatment of entrenchment cultures in inclined grounds
Inventor: DIMITROV PETAR D
IPC: A01B13/16
Filed: 1989-07-31
Abstract: This method and device are used in the treatment of entrenchment cultures, grown in inclined grounds in soil liable to water erosion. They result in a decrease in the flow of solids and liquids as well as an increase in soil aeration and moisture content, this resulting in higher yield. In addition, operation of the working implements is stabilized and it is possible to cultivate across the slope. With this method, cultivation, cutting-through and treading are carried out in sequence, simultaneously and transversely to the slope. Cutting-through and treading are carried out at a depth of two to four times greater than in cultivation. The device consists of a common frame (1), an operating section for each row mounted to the frame (2) with more than one cultivating operating element attached (3) and a cutting-through working element (4) and treader (5) hinged to the lower end of the cutting-through working element (4).

Title: Board repair for correcting defects in lumber
Inventor: CORTESE THOMAS
IPC: E04G23/02
Filed: 1989-10-24
Abstract: Boards of lumber or the like which exhibit defects such as knots or knotholes are repaired by cutting a bore through the board at the site of the defect and by filling the bore with a plug of conforming shape.  The width of the bore changes at a first location along its axis and undergoes a reverse change at another location in order to interlock the plug with the board.  The plug may be formed by filling the bore with hardenable mastic or by fitting conforming pieces of wood or the like into opposite ends of the bore, the pieces being abutted and secured together by adhesive.  The interlocking configuration of the bore and plug assures that the plug cannot be ejected from the board.

Inventor: ROTHARMEL JOHN
IPC: F16F9/46
Filed: 1990-03-02
Abstract: ABSTRACT   A variable damping shock absorber is disclosed.          The shock absorber has a two-wire electrical lead extending  into the piston rod.   The  electrical energy provided by the lead drives a drive motor, which rotates in alternating directions depending on the setting of an internal switch that switches upon occurrence of voltage spike, which occurs when the motor has driven an internal rotatable valve as far as the valve can go within the confines of rotation permitted by the valving.   The drive motor then drives an internal valve between an open and closed position,  which in turn opens and increases,  or closes or reduces, a path in fluid flow from one cavity to another as the piston moves within the shock absorber.

Title: Systems and methods for predetermining maximum pressure differentials for microporous hollow fibers employed in liquid-liquid extractions
Inventor: CALLAHAN ROBERT W
IPC: B01D61/00
Filed: 1990-03-28
Abstract: ABSTRACT      Systems and methods for predetermining maximum pressure differentials for particular microporous hollow fiber membranes and essentially immiscible feed and extractant liquids to be employed in liquid-liquid extractions include a test module having a number of such fibers formed into a loop between the opposing ends thereof.  A tubular sleeve element encompasses these opposing ends, and a potting compound positionally retains the opposing ends within the tubular sleeve.  The hollow fiber lumens are fluid-connected to a reservoir containing a pressurized feed liquid, and the loops of hollow fiber are immersed in an essentially unpressurized extractant liquid.  The pressure of the feed liquid is continually increased until there is an incipient presence of the feed liquid in the extractant liquid.  The pressure of the feed liquid at that incipient presence may therefore be used to calculate a maximum pressure differential tolerated by the microporous hollow fibers for the feed and extractant liquids used.  The system which detects the incipient presence may also be associated with full scale liquid-liquid extraction modules so that malfunctions and/or module failures may be determined.

Title: Jib stretching and folding device for crane
IPC: B66C23/70
Filed: 1990-04-26
Abstract: A jib stretching and folding device including an auxiliary connector mounted on a lower surface of a jib in the vicinity of a base end portion of the jib under the jib folded condition.  The auxiliary connector includes a cylindrical housing fixed to the lower surface of the jib and a connecting rod supported to the housing in such a manner as to be rotatable about the axis of the connecting rod substantially parallel to the lower surface of the jib and be movable along the axis of the connecting rod.  The jib is twisted about the axis of the connecting rod to effect a jib stretching or folding operation.  A twist guiding groove is formed on one of the housing and the connecting rod of the auxiliary connector, and an engagement projection is provided on the other of the housing and the connecting rod to engage the twist guiding groove.  When the jib is raised or lowered by a jib raising/lowering means, the engagement projection is moved in the twist guiding groove to generate a jib twisting force.          Thus, the jib is automatically twisted in the jib stretching or folding operation. Accordingly, a burden of labor of an operator in stretching and folding the jib can be reduced.          Further, the operation can be made continuous to thereby improve the efficiency of the jib stretching and folding operation.
