Title: High performance all-season tire
Inventor: BRAYER RANDALL R
IPC: B60C11/113
Filed: 1987-03-12
Granted: 1992-09-29
Abstract: Abstract of the Disclosure HIGH PERFORMANCE ALL SEASON TIRE     A radial ply pneumatic tire (10) has a tread portion (12) extending circumferentially thereabout. The tread has a plurality of circumferentially extending grooves (36,38,40,42) therein.  The axially outermost circumferential grooves (36,42) communicate with one another through two series of crisscrossed curved grooves (44,46), with the grooves of each series inclined in opposite directions across the tread. Drainage grooves (110) extend from the axially outermost circumferential grooves (36,42) to the nearest axial edge (TE1, TE2) of the tread in a substantially axial direction.  The tire exhibits good handling at high speeds on both wet and dry pavement, while also providing better snow traction than known high performance tires.

Title: Sensor-controlled hydraulic system with electroviscous fluids
Inventor: OPPERMANN GUENTER
IPC: G01D5/24
Filed: 1987-03-20
Granted: 1991-11-19
Abstract: A sensor-controlled hydraulic system with electroviscous fluids Abstract of the Disclosure A system-integrated motion sensor is provided fur moni-toring and adjusting the EVF system. The motion sensor is based on the concept that, with the aid of the elec-trodes (4,5) already present, which are used fur the vis-cosity control of the EVF in the hydraulic system, an electric current signal is simultaneously produced which is directly related to the rate of flow of the EVF between the electrodes which are either stationary or can be dis-placed with respect to each other. Thus the motion sensor consists of the electrodes (4,5) with the intermediate EVF layer (1) and a circuit (9,10,11) connected to the elec-trodes (4,5) for measuring the electric signal produced by the motion. The measured signal thus obtained can advant-ageously be used for adjusting or controlling the viscosi-ty of the EVF layer. For this purpose the measured signal is compared with a preadjusted value and the difference is used for controlling a high-voltage device which provides an output voltage dependent on the control voltage. This output voltage is fed back to the electrodes (4,5) of the EVF layer (1) and in turn influences the viscosity. Thus the measuring sensor for the motion, i. e. the EVF layer together with the associated electrodes (4,5), simultane-ously forms the regulating unit for controlling the motion.

Title: Apparatus and method for dispensing fluid materials
Inventor: PRICE RICHARD P
IPC: B05B12/02
Filed: 1987-09-14
Granted: 1992-05-05
Abstract: ABSTRACT APPARATUS AND METHOD FOR DISPENSING FLUID MATERIALS        Apparatus and method for dispensing fluid material whereby the  fluid  is  discharged  from a nozzle onto a workpiece.  Delivery of fluid to the nozzle is controlled by a metering valve located in close proximity to the nozzle.   The flow of dis-pensed  fluid  is  sensed  by  a  pressure  transducer disposed  to  sense  the  pressure  drop  across  the nozzle.  The pressure transducer generates a feed-back signal which can be applied by way of a closed loop control system to an electropneumatic servo-valve which operates a double-acting air cylinder which in turn operates the metering valve to control the pressure drop across the nozzle thereby con-trolling the flow of dispensed fluid in accordance with  a  driving  signal.   Where  the  dispenser  is carried by a robot, the driving signal can be cor-related to the relative speed between the workpiece and the nozzle to accurately control the amount of fluid per unit length contained in a bead deposited on the surface of the workpiece.  Due to the rapid response of  the  system  such  precise  control  is possible even during relatively rapid changes in the Abstract (cont'd) relative speed between the nozzle and the workpiece. Also  disclosed  are  means  for  insuring  that  the volume  of  fluid  dispensed  over  a  predetermined interval corresponds to a desired setpoint thereby correcting for changes in the intrinsic viscosity of the dispensed fluid as may be caused by changes in its temperature.

Title: Beach erosion control device
Inventor: SCHAAF CECIL
IPC: E02B3/06

Granted: 1991-06-18
Abstract: BEACH EROSION CONTROL DEVICE   ABSTRACT OF THE DISCLOSURE   A concrete module for at least partial submergence in the surf to dissipate the energy of wave action and to promote the deposition of beach-restoring sand and pebbles comprises a series of passages which converge toward the shore-facing side of the module and terminate in an upwardly-directed opening which deflects the incoming water flow upward to further dissipate the wave energy and to create a reaction force on the module which tends to rotate or tilt it toward the shore. This tendency aids in neutralizing the natural tendency of barriers to rotate toward the sea as a result of sand being scoured out from beneath the seaward side of the barrier as a result of downwardly-deflected incoming wave energy.

Abstract: ABSTRACT    An improved flexible graphite fabric gas diffu-sion cathode for an electrolytic cell has a first hyd-rophobic cathode surface contacting electrolyte in the cell and a second cathode surface forming an upper sur-face of the cell.  The improvement comprises a plural-ity of perforations in the flexible cathode to provide a series of vents, each perforation having sufficient open area that the force of gravity on the electrolyte is greater than the capillary forces of the perfora-tion on the electrolyte.  This prevents a localized nonuniform flow of electrolyte in the cell when the flexible electrode is disposed in a generally horizon-tal position with the first surface contacting the electrolyte and the second surface forming an upper surface of the cell.

Title: Electromagnetic flowmeter for conductive and dielectric fluids and its applications in particular in oilfield
Inventor: CODAZZI DANIEL
IPC: G01F1/64
Filed: 1987-11-24
Granted: 1990-12-04
Abstract: ABSTRACT     The invention is a non-intrusive system for measuring the flow rates of insulating or conducting fluids in conduits. It results from the combination of an elec-tromagnetic flowmeter, operating with conducting fluids, and of a triboelectric noise cross-correlation flow-meter, operating with insulating fluids. The system is equipped with a non-intrusive device for measuring fluid conductivity. The electronic signal processing unit uses the conductivity value to decide which of the two sen-sors is providing a signal effectively representing the fluid flow rate.          The electromagnetic flowmeter may use electrodes of small cross-section in contact with the fluid or, more advantageously, it may be of the capacitive type using larger section electrodes isolated from the fluid.
