Abstract: Hopper apparatus for controlling the discharge of lading from a hopper of a railway car through an opening in which a door opens and closes the opening and is moved from the closed position to the opening position by rotatable gears and by racks attached to the door.  The door is curved and rides on tracks disposed to urge the door to its closed position by gravity.  The gears are rotated by a drive shaft having end portion for receiving a rotating tool,and the door is locked in its closed position by locking means including a ratchet wheel on the drive shaft and a pawl controlled by a handle assembly which, in the locked position of the door, covers the end portions of the drive shaft so that it is necessary to move the handle assembly to expose the end portions and to release the pawl from the ratchet wheel before the drive shaft can be rotated to open the door.          Also, a relationship between the number of teeth on the ratchet wheel and the door drive to provide small locking increments and a spring bias on the pawl to prevent disengagement of the pawl from the ratchet wheel during car transit.

Abstract: To provide a docking device which can improve stereo effect and tone quality, and which allows a portable computer to have the same functions as a desktop personal computer, speakers are built into respective projecting portions projecting from the two sides along the width of a support portion of a main body.   This enables improvement  of  both  stereo  effect  and  tone  quality  from  a conventional case where speakers are incorporated in the main body facing the back.  Furthermore, it becomes possible to accommodate in the main body a full-size AT bus card which is difficult to accommodate conventionally.

Title: Call monitoring system for intelligent call processing
Inventor: IYOB HANNIBAL
IPC: H04Q1/20
Filed: 1994-08-31
Granted: 1998-09-29
Abstract: Increased reliability for intelligent call processing systems is provided by collecting information from communications between the network database, the subscriber database, and the network switch. Message transfers between these network elements are monitored and correlated to identify those messages corresponding to a particular call. The messages for the call are analyzed to determine which database generated the instructions for routing the call. In particular, by comparing the routing number returned to the interexchange switch with the routing instruction information supplied by the subscriber's database, it can be determined whether the call was routed according to instructions from the subscriber's database.

Title: Summary catalogs
Inventor: NEEMAN YUVAL
IPC: G06F17/30
Filed: 1995-01-06
Granted: 2005-11-22
Abstract: A system provides support for the use of summary catalog data structures. In particular, the system defines such summary catalogs as data structures and provides standardized methods for operating on the data structures.    The summary catalogs provide a convenient and highly available mechanism for obtaining information regarding files in the system. The summary catalogs are closely tied to queries in that the summary catalogs store query results. The summary catalogs may be encapsulated into objects that hold selected properties that are derived from other objects in a query or may be formed by other mechanisms. Copies of a summary catalog may be kept consistent using replication that propagates changes. In addition, consistency of summary catalogs with the source objects from which they originated may be maintained.

Abstract: A control system controls the vehicle having turn signal lights mounted on both sides of the vehicle in response to deflection of a manually operated turn signal.  The control system includes a control unit which senses vehicle speed and automatically interrupts a flashing mode after a flashing duration which is dependent upon the sensed vehicle speed. The turn signal control unit shuts off the flashing mode in response to deflection of the turn signal lever only for a brief time period and enables the flashing mode in response to deflection of the turn signal lever for a period of time which is longer than a pre-set time period.  The control unit prevents cancellation of the flashing mode in response to a repeat deflection of the turn signal lever only for the brief time period.  The control unit also cancels a first flashing mode associated with deflection of the turn signal lever in a first direction and enables a second flashing mode associated with deflection of the turn signal lever in a second direction in response to brief deflection of the turn signal lever in a second deflection direction.  The control unit maintains operation of the flashing mode in response to deflection of the lever for a period of time longer than a pre-set time period.

Abstract: A manufacturing process to produce a laryngeal mask (10) substantially as described in UK Patent GB2205499B consists in a mould (20, 21, 23, 24) which manufactures the inflatable annular ring (13) formation of the device in an inverted form. This allows a more rigid core (20) in the cavity mould or alternatively a dip-moulding process, which in turn permits greater accuracy in control of wall thickness. An alternative form of the mould eliminated the need to assemble a further components by incorporating the latter into the same single moulding process. And in a further alternative embodiment, the same single moulding process additionally provides an integrally formed inlet for oesophagus drainage, independent of the larynx-venting function of the mask per se.

Abstract: A stairway for a motor coach is located in one side wall of the motor coach immediately adjacent the front wall and in front of the front wheel well. The stairway co-operates with a hinged door mounted at the front wall and openable to an angle less than 90° from the coach side. The stairway is defined by a plurality of steps of equal riser height together with two vertical side walls each on a respective side of the stairway. The walls are smoothly curved around a center of curvature rearwardly of the stairway and to one side of the coach so that the stairway smoothly curves from a front edge at the doorway to a ramp section of the aisle commencing at a line at right angles to the side of the coach. The front edge of each step is at an angle to the front edge of the next step so that the steps provide gradual turning from the side of the coach to the front of the aisle. The stairway commences initially into the coach in a direction slightly toward the front of the coach so as to co-operate with the door in directing the passengers along the side of the coach, into the stairway, around the stairway and onto the aisle.

Abstract: A modem that matches itself to a central office codec to which it is connected and incorporates encoding of the data. An echo canceller following the central office codec subtracts an estimate of the echo introduced in the central offices. More particularly, digital data applied to the modem is multi-level encoded and mapped onto a subset of the levels recognized by the central office codec. In an illustrative embodiment, the multi-level encoding encodes the two least significant bits in the binary representation of the levels delivered by the modem. The least significant bit is encoded with a code that is more robust than the code of the next-to-least significant bit, in recognition of the fact that errors in the least significant bit are much more likely. The corresponding echo canceller in the network first estimates the echo and subtracts it from the signal applied to the digital network by the central office. Thereafter, a decoder decodes the received signal in stages. In the first stage, the least significant bit of symbols is identified based on a first error correcting code. In the second stage the remaining bits of the symbols are determined, with the aid of a second error correcting code and the results of the first stage. Block or convolutional encoding can be used.

Abstract: A key cutting machine includes a cutter wheel, a key follower and a key positioning fixture for retaining a master key and a key blank in defined positions. Longitudinal and lateral displacement elements displace the cutter wheel and the key blank relative to each other.  First and second electronic position sensors generate cutter wheel longitudinal and lateral position signals which electrically define the position of the cutter wheel relative to the key blank blade.  A mode control system selectively operates the key cutting machine in either an analog mode where the bit notch pattern of a master key is mechanically traced and duplicated in the key blade blank or in a digital mode in which an electronically defined bit notch pattern is electrically duplicated in the key blank blade without reference to or tracing the master key bit notch pattern.
