Abstract: CHAIR BACK WITH POLYMER SPRING   ABSTRACT OF THE DISCLOSURE This specification discloses a resilient polymer spring for controlling movement of one chair member with respect to another chair member such as the seat back of a secretarial posture chair with respect to a vertical support.  A chair back mounted on a chair back support plate is pivotally connected by a resilient arrangement to a housing slideably mounted on a vertical post.  The resilient arrangement includes a member of a resilient material with ends, each end having enlarged heads with an opening ex-tending through the heads and a pivot groove positioned between the enlarged heads.  Upon application of an external force, the chair back pivots about the groove and compresses the enlarged heads thereby closing the opening through the enlarged heads.  The chair back is positioned at an inter-mediate position when there is no external force applied to the resilient spring.

Abstract: ABSTRACT OF THE DISCLOSURE An arrangement is provided for compensating for detrimental magnetic influence between two or more rows of transverse electrolytic pots or cells for producing aluminum, by electrolytic reduction in a molten bath, in which most of the current conducted from the rear side of a pot in the pot row to the succeeding pot in the row, is carried by two or more conductors underneath the pot.  Another and smaller proportion of the current conducted to the suc-ceeding pot in the row is conducted in its entirety around that short side of the pot which faces the magnetically dominating adjacent pot row.  Preferably, this smaller proportion of the current amounts to a maximum of 20 per cent of the total electrolysis current.

Abstract: ABSTRACT An electronic hybrid circuit for matching a two wire telephone circuit to a four wire telephone circuit is described.  In one embodiment, the circuit includes a variable impedance circuit one end of which is driven by a reception signal on the four wire side and the other end of which is connected to a terminal of the two wire circuit.  The impedance of the vari-able impedance circuit varies according to the characteristics of the two wire circuit.  The hybrid circuit also includes an adder which adds in reverse reverse phase a half value of the reception signal on the four wire side to a signal from the two wire side, the resultant signal being a transmission signal on the four wire side.  According to the invention matching is achieved regardless of variable factors such as length of two wire circuit and terminal impedance at its other end.

Abstract: ADJUSTABLE GUIDE VANES FOR AN AXIAL FLOW ROTARY SEPARATOR             Abstract of the Disclosure In an axial flow rotary separator for a combine harvester, a series of parallel guide vanes are mounted inside the upper portion of the separator housing.  The guide vanes are each helically disposed and parallel to each other and they cooperate with the separator rotor so that as the rotor is rotated crop material which has been fed to an upstream end of the separator is propelled downstream as a mat in the annular space between rotor and housing, the guide vanes engaging the mat of material and deflecting it downstream as it is propelled circumferentially by the rotor so that any given portion of the mat is propelled downstream in an approximately helical path.  The guide vanes are characterized in that they have a first fixed or leading portion which first engages the crop material and a second trailing portion which is adjustable with respect to the first and with respect to the separator housing so that the effectiveness of the guide vane as a whole may be selectively varied with regard to its helically propelling or deflecting effect.  Several embodi-ments are disclosed including a guide vane fixedly pivoted at its leading end and with its trailing end radially adjustable inwards and outwards; a version in which a trailing portion of the guide vane is adjustably pivotable about an approximately radially extending pivot axis; a version in which the length of the trail-ing portion is adjustable through a telescoping arrangement and another in which a rotatable or displaceable element effectively provides three interchangeable housing wall portions, each wall portion carrying a guide vane trailing portion of a different pitch.

Abstract: APPLICATION FOR LETTERS PATENT FOR    "KERFED EDGE GYPSUM BOARD HAVING IMPROVED EDGE STRENGTH"     ABSTRACT     Disclosed is a gypsum board having a kerfed edge along substantially the full length of at least one edge wherein the kerf has sidewalls inclined opposingly inwardly toward one another but do not intersect and are joined by a bottom surface of uneven profile characterized by alternately and irregularly spaced projections and depressions.  The uneven bottom surface and each sidewall meet at a jagged intersection.  Said kerfed edge provides enhanced strength in a direction perpendicular to the sidewalls providing improved board retention by flanged supports over that of conventional mechanically sawn kerfed edged boards.  A process for providing kerfed edge gypsum board is also disclosed which comprises projecting into the board edge a first and second fine stream of aqueous liquid which incline toward one another at an-gles of incidence to a line perpendicular to the board edge which provides a combined angle therebetween of from about 3° to about 20°.  Both first and second fine streams of aqueous liquid are projected at a pressure sufficient to cut to substantially the same depth of from about one-quarter to about three-quarter inches.  The process is dustless and provides a kerf having two opposing sidewalls inclined toward one another and joined by a bottom uneven jagged surface providing increased strength exceed-ing that of boards kerfed by conventional mechanical sawing proc-esses.

Abstract: RESTRAINING DEVICE FOR USE IN DRYING LUMBER                  ABSTRACT OF THE DISCLOSURE         A restraining device is used in a dry kiln with a load of green lumber in order to reduce warpage during drying and cooling.  A single restraint device is comprised of a pair of inverted leaf springs joined together at their centers and having a strap extending from one end of the top spring about the load of lumber and terminating at the other end of the top spring together with a tensioning device for the strap.  Before the load of lumber is placed in the dry kiln, the tensioning device will draw down both the bottom and top leaf springs close to the load where the tensioning device will lock them in place.  During drying, as the load shrinks, the top spring will be relaxed while the bottom spring will maintain a force across the width of the load, thereby substantially reducing warp.

Abstract: Machines for handling seeds ABSTRACT  OF  THE DISCLOSURE           A machine for picking up seeds from a mass of seeds and depositing the seeds individually comprises a row of suction heads each having a suction duct terminating in an orifice and a container for holding the mass of seeds.   The row of heads are pivotally mounted and are provided with a driving mechanism which swings the heads to and fro along a path between a pick-up position in which each of the orifices is adjacent the container and a discharge position in which seeds picked up by suction through the orifices are discharged.  In order to enable each head to discharge at the discharge position only a single natural seed rather than a pelleted seed, a wiper member is provided and extends parallel to the row of heads in their path between the pick-up position and the discharge position.   The wiper member has a curved surface and the heads swing close to this surface just before they reach the discharge position. The surface is so shaped that a tapering space is formed between the surface and a flat circular surface surrounding the orifice of each head and this tapering space is of sufficient width to hold a single seed, but squeezes surplus seeds away from the orifice of each head as the orifice passes over the curved surface.   Preferably means are provided for applying air pressure to the duct of each head when the head reaches the discharge position to blow the seed held by the orifice from the head and discharge it into a discharge chute.  Preferably also the container is an elongated tray having a bottom of V-shaped cross-section and the tray is fitted with a vibrator by which it is vibrated for a short time as the heads reach the pick-up position which is adjacent the apex of the V.   The vibration tends to shake the seeds into a single layer on the tray and they advance down one sloping side of -the bottom of the tray to form a row along the apex of the V where they are picked up.   This causes each head to pick-up fewer seeds each time it reaches the pick-up position than would otherwise happen.
