Abstract: Abstract of the Disclosure A variable displacement hydraulic motor/pump apparatus 10 of the axial piston type is described that is more efficient over a wider range of speeds than previous devices. The apparatus 10 includes a main shaft 17 having a piston rod carrier 30 extending radially outward from the shaft for supporting a plurality of radially and angularly spaced piston rods 37. The piston rods 37 are double ended and held axially stationary with respect to the main shaft.          Pistons 51 and 52 are mounted at the ends of the piston rods 37.          Annular cylindrical barrels 60, 61 are supported by barrel carrier assemblies 84, 85 respectively circumferentially about the main shaft.          Torque is transmitted between annular cylinder barrels 60, 61 and the main shaft 17 by the carrier 30. The barrels have piston cavities 65 formed therein for receiving corresponding pistons 51, 52. The barrel carrier assemblies 84 and 85 are supported by trunnion elements 94 and 95 for enabling the carrier assemblies 84 and 85 to pivot about tilt axes 97 to vary the angular orientation and volumetric displacement of the barrel cavities 65 with respect to the pistons 51, 52. The apparatus may be operated as a motor, as a pump, or as a combination pump and motor.

Abstract: Abstract A plant nutrient composition is obtained by extracting a complex fraction comprising a mixture of water-insoluble long-chain organic compounds from natural plant material, especially from rice bran wax. The fraction is preferably obtained by saponifying rice bran wax and recovering the unsaponifiable residue. The fraction can be employed in dilute aqueous emulsion form as a foliar spray to enhance the growth and yield of many crops, such as rice, wheat and maize, especially in marginal agricultural areas.

Abstract: ABSTRACT The invention relates to a mechanism for adjusting the feed length of a rack and pinion roll feed mechanism of the type generally used for feeding strip stock into presses.  The feed comprises a pair of opposed rolls adapted to grip stock during the feed cycle wherein at least one of the rolls is driven in an intermittent fashion by a rack and pinion mechanism including an overrunning clutch.  The rack and pinion mechanism is driven by a connecting rod connected between it and the motorized feed length adjustment mechanism according to the present invention, which is mounted to the crankshaft extension that generally extends out of the crown of the press.  The feed length adjusting mechanism comprises a hub member connected to the press shaft, a throw block connected to the hub and having a slideway therein, a slide received in the slideway for sliding movement in a direction generally perpendicular to the axis of rotation of the hub member, and a bearing for rotatably connecting the slide to the connecting rod.  The slide is locked to the block by means of a lock mechanism comprising a cylinder in the slide having a lock piston therein and a fluid inlet for pressurizing the cylinder to thereby lock the piston against a surface of the slideway.  A lead screw is threaded connected to the slide and rotated by a bidirectional pneumatic motor mounted to the block, whereby rotation of the lead screw causes the slide to translate within the slideway.  This changes the length of the eccentric connection between the rotating block and connecting rod thereby proporionately changing its stroke and the amount of strip stock which is fed into the press during each cycle of the feed mechanism. A fluid union mounted to the adjustment mechanism supplies pressurized air to the cylinder inlet and to the pneumatic motor, and the union comprises three fluid passages contained in a rotatable inner member and three conduits connecting the passages to the cylinder and motor inlets, respectively.

Abstract: RECOVERY OF OIL FROM TILTED RESERVOIRS                         ABSTRACT OF THE DISCLOSURE          A method for recovering oil from a tilted oil-bearing reservoir having a water zone in fluid communication with and directly below an oil zone wherein a large amount of solvent is injected along the water-oil interface so that a part of the solvent fingers into the oil, lowering its viscosity and making the oil more mobile for production.  The remainder of the solvent is driven through the reservoir by a water flood wherein the rate is controlled slow enough that gravity minimizes fingering of the water into the oil layer, sweeping oil toward the production well.  Solvent stimulation of the producing well provides additional incremental recovery and encourages the flooded oil toward the production well.

Abstract: ABSTRACT A broadband data communication system provides effective increased bandwidth for the transmission of electrical information signals in the system. The signal transmission medium is a coxial cable having main receive and transmit branches, and having drop line pairs connected to the main branches at junction points.  A plurality of user devices is connected to each drop line pair, including a particular set connected to a particular pair.  Each user device of the set can transmit and receive signals of local frequencies in a selected bandwidth.  Frequency isolation means, is connected to the particular drop line pair adjacent its junction point, and passes signals of the local frequencies only from the transmit drop line to the receive drop line, while blocking signals of the local frequencies from transmission over the main cable branches.  The particular set of user devices and the filter isolation means together define a subnet.  Other subnets can use the same bandwidth of local frequencies without interference, thereby increasing the effective bandwidth of the system.  For communication between subnets, a master unit is provided in a subnet which can receive and transmit both at the local frequencies and at master frequencies outside the selected bandwidth; the frequency isolation means passes the master frequencies.  The master translates communications from the subnet devices, at local frequencies, into master frequencies for transmission out of tile subnet, and receives communications from outside the subnet at master frequencies for translation to local frequencies and transmission to the user devices of the subnet.
