Title: Air bag and walking beam construction
Inventor: KOOISTRA JAMES T
IPC: B60G11/27
Filed: 1991-05-07
Granted: 1994-04-19
Abstract: AIR BAG AND WALKING BEAM CONSTRUCTION ABSTRACT OF THE DISCLOSURE              A set of bag carrying saddles replace the leaf springs of conventional walking beam assemblies and operate in conjunction with a pair of linear stabilizing arms and shock absorbers thereby giving a traction distribution of approximately 25% per wheel. The use of walking beams in conjunction with shock absorbers gives a suspension system particularly suitable for extremely rough terrain because it operates on an approximate 2:1 ratio with the air bags. The saddles include vertical side plates having diagonal forwardly and upwardly extending front portions pivotally mounted to each chassis member of the vehicle and which are also pivotally connected to the walking beams intermediate the ends of the beams. Air bags operatively extend between the saddles and the chassis members.

Title: Packet switching method and system with self-routing switch
Inventor: TANABE SHIRO
IPC: H04L47/6275
Filed: 1991-08-16
Granted: 1997-06-24
Abstract: In a packet network having a plurality of local switching units each connected to a plurality of packet lines and at least one cross-connect unit connected to each local switching unit through at least one transit line having a predetermined transmission capacity a plurality of virtual paths for interconnecting the plurality of local switching units through the cross-connect unit are defined on each transit line, without fixedly assigning communication bandwidths to individual virtual paths and, in respect of the individual transit lines, values of communication bandwidths assigned to virtual channels which have already been established in virtual paths present on the transit lines are stored.  When a request for setting a new call is originated, communication bandwidths of first and second transit lines on which exists a virtual path to form thereon a virtual channel for the call are checked for their margin enough to accept assignment of a bandwidth requested by the call, the first transit line lying between the cross-connect unit and an originating local switching unit and the second transit line lying between the cross-connect unit and a terminating local switching unit.  If the first and second transit lines have a margin enough to accept the assignment of a bandwidth requested by the call, the virtual channel for the call is established on the virtual path and values of communication bandwidths assigned to the first and second transit lines are updated.

Title: Power system and scan method for liquid crystal display
Inventor: KLINGER LANCE T
IPC: G02F1/133
Filed: 1990-06-29
Granted: 1998-01-20
Abstract: A structure and method for controlling a liquid crystal display takes advantage of the sharp reflectance change over a small voltage change for new liquid crystal display materials, applying ON and OFF pixel voltages very close to the transition voltage of the liquid crystal material and regulating the applied voltage to remain reliably near and on the desired side of this transition voltage. Also, a net zero DC voltage across pixels of the crystal is maintained using a switching mode close to half the frequency of prior art modes. Driving voltages are provided by a switching regulator rather than the prior art voltage divider, resulting in a significant reduction in operating power. The preferred switching regulator generates only three additional voltages for driving rows and columns of the display, in contrast to the five generated voltages of the prior art voltage divider. An on/off voltage regulator alternately provides or does not provide power to a primary coil (P81), thereby controlling voltage across capacitors (C81, C82, C83, C84) associated with secondary coils (S81, S82, S83, S84). This gives accurate voltage control over a wide range of display loads. This voltage regulator is controlled preferably by the low voltage applied across pixels during the time when the pixels are not in the selected row, that is, during the time when the logic state of a pixel is not provided to the pixel.

Title: Continuous filter
Inventor: KEILLOR PETER T III
IPC: B29C48/08
Filed: 1991-10-15
Granted: 2000-08-08
Abstract: Filtration process and filters for use with materials such as, but no limited to, polymeric melts, utilizing a band (18) of a filter medium sealed in a housing (10) by sealing rollers (24, 26) to seal the polymeric material from leaking to the outside of the housing. In one embodiment, the sealing rollers make it possible to advance the filter medium through the housing continuously. In various embodiments, the filter medium can be advanced either by a take-up spool (32) or by driving the sealing rollers and the rate of movement of the filter medium through the housing can be controlled to maintain a constant pressure drop across the filter. Maintaining constant conditions through continuous advancement of the filter medium during filtration yields higher product quality and dimensional stability.

Granted: 2000-07-18
Abstract: A gimbal vibration isolation system suitable for use with an inertial platform to enable accurate positioning of the platform independently of a presence of vibratory translational movement upon a gimbal housing enclosing the platform employs a frame assembly centrally located within the platform for pivoting the platform and for isolating the platform from vibration. The platform is formed of two plate assemblies disposed on opposite sides of the frame assembly, with each of the plate assemblies carrying portions of a laser gyro and ancillary optical and electronic equipment. The gimbal housing includes a drive ring rotatable about a central axis and encircling the frame assembly which is connected to the drive ring. A central portion of the frame assembly carries a pivot which pivotally supports the platform. An electromagnetic actuator is located at each of a plurality of positions located circumferentially around the central axis wherein each actuator has a first part connecting with the frame and a second part connecting with both plate assemblies of the platform to accomplish a pivoting between platform and frame assembly upon activation of each actuator. The frame assembly further includes a plurality of vibration isolation elements of resilient material disposed symmetrically about the central axis and being connected between the first parts of respective ones of the actuators and the drive ring to allow operation of the actuators in an environment substantially free of translatory vibrational movement.

Title: Method and apparatus for testing a spring-loaded safety valve
Inventor: KUENH EDMUND
IPC: F16K37/00
Filed: 1994-05-05
Granted: 2002-01-22
Abstract: A method for testing a spring-loaded safety valve includes ascertaining a closing pressure of the safety valve by selecting a pressure of a medium acting on a closing device of the safety valve to be less than an expected closing pressure. The closing device is lifted with a force origi-nating at an auxiliary lifting device by acting upon a chamber below a lifting bell in the lifting device with an auxiliary medium. Then the safety valve is closed by divert-ing the auxiliary medium out of the chamber and simultaneous-ly a supply of auxiliary medium is passed through the chamber and diverted. Pressures of the medium and of the auxiliary medium are measured as the safety valve is closing. The closing pressure is determined from the measured pressures, from an effective area ratio of the lifting bell and a valve plate of the closing device, and from a constant, in accor-dance with the equation:        P S = P P + (P H .cndot. V A)/(m + 1).   wherein P S is the closing pressure of the safety valve, P P is the measured pressure of the medium acting upon the closing device in the closing process, P H is the measured pressure of the auxiliary medium acting upon the lifting bell in the closing process, V A is the ratio of the effective area of the lifting bell and the closing device, and m is a constant. An apparatus for testing the safety valve is also provided.
