Granted: 1991-08-13
Abstract: LIQUID/ABRASIVE JET CUTTING APPARATUS      Abstract of the Disclosure The Apparatus confines abrasive slurry in one chamber of a dual-chamber reservoir having a piston sealing between the two chambers.  Pump-pressured water is conducted to the other chamber (a) to displace the piston and, consequently, (b) to pressure the slurry.  A fluid line conveys the pressured slurry to a central, orifice-terminated, channel formed in the axial center of a nozzle, and another fluid line conveys pump-pressured water to an annular conduit, formed in said nozzle, which circumscribes the central channel. The annular conduit also terminates in an orifice.  Both orifices are axially aligned, the latter one being of greater diameter than the former.  Upon emerging from the aforesaid conduit and channel, the water and slurry accelerate together in a convergent chamber of the nozzle to discharge via the larger-diameter, final exit orifice.

Title: Jack assembly for railroad cars
Inventor: JACKSON KENNETH J
IPC: B66F3/24
Filed: 1987-12-01
Granted: 1991-01-22
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosed jack assembly has an elongated structural beam of sufficient length to extend between and beyond the two rails of a railroad track, to be supported on top of the rails.  A compact power lift cylinder, in the form of a multiple-sleeve power cylinder, is connected to the beam; and a car engaging plate is coupled to the power lift cylinder, to be moved in a direction transverse to the beam.  The silhouette of the beam, power lift cylinder and plate is low, when the power lift cylinder is contracted, to allow them to be fitted with clearance to a lifting position, under a railroad car with the beam extended across the track rails and the car engaging plate vertically aligned under the railroad car frame.  The power lift cylinder has a power stroke sufficient to lift the overlying railroad car enough above the rails to remove the railroad car completely from one wheeled truck assembly, for replacement or the like.  Blocks carried on the beam can be shifted against the raised car engaging plate, to hold it independently of failure of the power lift cylinder.  A pumping system for the power lift cylinder is located laterally beyond the one side of the road car, with operating controls within easy reach of someone standing at this location.  The pumping system can optionally be secured as a unitary part of the jack assembly, or as a separate unit.  The jack assembly can be used from either side of the car, typically at a location between the wheeled truck assemblies supporting the car.

Title: Spring damper for a clutch driven disc assembly
Inventor: BASSETT MICHAEL L
IPC: F16D13/64
Filed: 1987-12-02
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE An improved spring damper drive for a clutch driven disc assembly is disclosed.  The assembly includes a pair of spaced outer covers connected to a generally cylindrical central hub.  An annular support plate is disposed about the hub between the outer covers and is rotatable relative thereto throughout a limited distance.  The outer covers and the support plate each have respective pluralities of openings formed therethrough.  The openings are adapted to be aligned with one another so as to receive and retain respective pairs of dampening coil springs therein.  Each spring opening is shaped generally in the form of a truncated sector, having a linear inner wall oriented perpendicularly to a bisecting radius of the outer cover, a pair of end walls extending perpendicularly outwardly from each end of the linear inner wall, and an arcuate outer wall connecting the two end walls.  The peripheries of the spring openings formed in the two outer covers are defined by flanges which extend thereabout in opposed fashion.  The radially outermost corners of each of those flanges are formed having shoulders which extend inwardly from the arcuate outer wall.  The shoulders are provided to re-position the ends of the coil springs according to the amount of compression thereof caused by rotation of the support plate relative to the outer covers.  As a result, the springs are properly positioned throughout relatively large amplitudes of angular displacement of the support plate relative to the outer covers, and premature wear of the springs is avoided.

Abstract: PLURAL LEVEL BEAM-FORMING NETWORK               ABSTRACT                   A beam-forming network (98) employs one or a plurality of first transmission delay lines (168, 170, 172, 174) for receiving transmit signals (T1-T4) applied thereto, and a plurality of second transmission lines (176), which serve as line summers. Each of the first transmission delay lines has first and second portions (168a, 168b; 170a, 170b; 172a, 172b; 174a, 174b) spaced apart from one another so as to define first and second levels displaced from one another. The set of second transmission lines (176) are arranged in first and second subsets (176a, 176b) which are respectively disposed adjacent to the first and second levels and respectively associated with the first and second portions of the first lines, such that the first subset of second lines is coupled to the first portion of the first lines, and the second subset of the second lines is coupled to the second portion of the first lines. Further, selected ones of the first subset of second lines are disposed adjacent to selected ones of the second subset of second lines in order to facilitate simple and orderly routing of transmission lines (126, 128, 130) between the beam-forming network and a novel equal power amplifier system (100) described herein.

Filed: 1988-03-30
Granted: 1990-10-30
Abstract: Abstract of the Disclosure A dual media network interface module includes an electrical  network   interface  and  an  optical  network interface each having a transmit port to which signals to be transmitted  on  the  associated  network  are  applied  and  a receiver port at which signals received on the network are generated.  The receiver port of each interface is connected to  the  transmitter  port  of  the  other  interface  so  that signals received on either network are retransmitted on the other network.  Blocking circuits block the receiver signal of  a  LAN  which  is  transmitting  during  the  transmitting interval  plus  an  interval  which  exceeds  the  worst  case propagation  time  for  the  associated  network  to  prevent endless repetition of a signal.   A preferred form of the module  includes  a  pair  of  controller  interfaces  having transmit  ports  and  receiver  ports  connected  to  the corresponding ports of the other controller interface and of the electrical and optical network interfaces to provide bi-directional communications between all devices connected to the module.  The modules can be used to interface electrical and optical nodes in a network, to expand both electrical and   optical   networks,   and   to   interconnect   various combinations of electrical and optical local area networks.

Granted: 1993-01-05
Abstract: Abstract A detector system for sensing the progress of an ISV process along an expected path comprises multiple sensors each having an input port.  The input ports are distributed along the expected path of the ISV process between a starting location and an expected ending location. Each sensor generates an electrical signal representative of the temperature in the vicinity of its input port.  A signal processor is coupled to the sensors to receive an electrical signal generated by a sensor, and generate a signal which is encoded with information which identifies the sensor and whether the ISV process has reached the sensor's input port.  A transmitter propagates the encoded signal.          The signal processor and the transmitter are below ground at a location beyond the expected ending location of the ISV process in the direction from the starting location to the expected ending location.  A signal receiver and a decoder are located above ground for receiving the encoded signal propagated by the transmitter, decoding the encoded signal and providing a human-perceptible indication of the progress of the ISV process.
