Title: Saw blade tensioning arrangement
Inventor: JANSON KURT
IPC: B27B13/08
Filed: 1987-11-24
Granted: 1992-10-06
Abstract: Abstract A saw blade tensioning arrangement for band saws and like machines which includes a hydraulic cylinder having arranged for movement therein a piston which is intended to activate saw blade tension control means.  The blade tension is, in this way, dependent on the hydraulic pressure in the cylinder. The arrangement includes means for pneumatically regulating the hydraulic pressure, these means including a pneumatically operated pressure booster and means for activating the pressure booster at the end of a working stroke of the hydraulic piston, therewith to tension the saw blade to the desired working tension, this working tension being determined, inter alia, by the blade width.

Abstract: Abstract of the Disclosure An electrohydraulic servo system which includes a plurality of pressure compensated flow control servo valves for feeding hydraulic fluid from a variable displacement pump to associated actuators and loads.  A closed-loop velocity-control servo system is coupled to each servo valve, and is responsive to velocity command inputs from an operator and to feedback signals from the respective loads for providing flow control signals to the respective servo valves.   A pump controller receives the valve flow control signals, derives associated valve flow rates from predetermined functional characteristics of the pressure compensated valves, and obtains a total flow demand as a function of the sum of the indicated individual valve flow rates.  A pump displacement command is derived as a combined function of total  flow demand and pump speed  to accommodate volumetric inefficiencies which vary with speed, and the displacement command signal is fed to a pump displacement servo control loop for controlling pump output.  Displacement command is limited as a function of power available at the engine coupled to the pump to prevent engine stall.

Abstract: DILATATION CATHETER WITH THIN GUIDE WIRE            Abstract Dilatation catheter and relatively thin guide wire for use in coronary angioplasty.  The luminal opening in the catheter is only slightly greater in diameter than the guide wire, and the luminal wall in close proximity to the guide wire supports the relatively thin wire against buckling and enhances the transmission of torsional and axial forces through the wire.  In the disclosed embodiment, the catheter is a balloon dilata-tion catheter, and the proximal end portions of the inner and outer tubular members which form the catheter are stiffer than the distal end portions to facilitate insertion of the guide wire and catheter into the cardiovascular system.  The distal end portion of the luminal opening is lined with a lubricious material such as Teflon to facilitate insertion of the relatively thin guide wire.

Title: Two dimensional acousto-optic signal processor using a circular antenna array and a butler matrix
Inventor: LEE JIM P
IPC: H01Q3/26
Filed: 1988-11-02
Granted: 1993-05-11
Abstract: ABSTRACT             An interferometric acoustooptic signal processor utilizing a circular antenna array to cover a 360 degree field of view. Each antenna element of the array is connected to an input port of a Butler matrix. The signals are phase shifted within the Butler matrix and applied to a multi-channel periodic Bragg cell, resulting in generation of one or more acoustic waves therein.  A laser beam is used to illuminate the Bragg cell and is modulated due to interaction with the acoustic waves, resulting in diffraction of the laser beam and generation of a diffracted beam pattern output from the Bragg cell.  A Fourier transform lens focuses the diffracted laser beam on a back focal plane at a point characterized by two perpendicular coordinates designating the input signal power spectrum and the angle of incidence in relation to the antennae, respectively.  By utilizing a circular antenna array with a Butler matrix a full 360 degree field of view is obtained using only one 2-D acoustooptic signal processor and the peak sidelobe to mainlobe level is reduced up to -30 dB. Furthermore, the accuracy and resolution of the processor are independent of frequency.

Abstract: DISPLAY WITH ENHANCED SCROLLING           CAPABILITIES        ABSTRACT OF THE DISCLOSURE            A computer display has a display processor connected to a presentation space buffer and a screen buffer. The presentation space buffer is larger than the screen buffer, and is divided into a plurality of partitions.  Each partition has a partition window which maps into the screen buffer.  If a partition is active, its associated partition window is written into the screen buffer at the mapped location.  The screen buffer periodically refreshes the display screen, so a plurality of partition windows are displayed to the computer user. One or more scroll groups can be defined, and one or more partitions can be assigned to each scroll group. Each defined scroll group has a vertical scroll trigger and a horizontal scroll trigger.  The display monitors the movement of the cursor within a partition window.  When the cursor gets close enough to a boundary of a partition window, to trigger a scroll trigger, the display shifts the partition window within its partition and writes this updated partition window into the screen buffer.  Updated partition windows are written into the screen buffer for the other partitions in the scroll group.

Abstract: A granular carrier is contacted in a reaction space with a continuous stream of liquid which contains a sufficiently wide flora of microorganisms and sufficient nutrients for the growth and /or preservation of the microorganisms until a sufficiently thick layer of microorganisms is attached to the carrier, while in the liquid 0.1-1.5 kW of mechanical energy per m<3> of reactor liquid, is dissipated at least partly in the form of gas bubbling through the liquid and the residence time of the liquid in the reaction space is kept lower than the reciprocal maximum growth rate of the microorganisms. More preferably an aerobic biomass attached to a carrier is produced, by applying liquids, wherein the growth rate is not limited by the concentration of nutrients and by adjusting a residence time of the liquid in the reactor of below 45 minutes.
