Title: Packet data communication system
Inventor: TYMES LAROY
IPC: H04L5/14
Filed: 1991-09-12
Granted: 2002-01-15
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange.

Title: Compression spring fluid motor
Inventor: WALTON FRANK
IPC: F03C1/007
Filed: 1992-02-26
Granted: 2003-12-02
Abstract: A reciprocating primary fluid driven motor has a stepped piston in a housing having a center hanging actuator rod which extends into the piston to periodically cooperate with an axially shiftable connector member in the piston which operates valves which establish the reciprocating stroke of the piston by opening and closing valve members on the larger and smaller faces of the stepped piston. A block member with compression spring drivers pivotally mounted inside the piston slides on the actuator rod during movement of the piston. The drivers are compressed in response to spaced stops on the actuator rod during continued movement of the piston until a sudden over-center movement of the block member shifts the connector to operate the valve members to cause reciprocation of the piston. Quiet operation during shifting is provided by shock absorbers. No sliding seal with the actuator rod is necessary. Provision for bleeding air from the housing chamber facilitates startup. The stepped piston is connected to a secondary fluid additive pump to inject metered amounts of secondary fluid into the primary fluid stream.

Title: Thermostatically controlled mixing valve
Inventor: MACDONALD ROBERT
IPC: F16K31/68
Filed: 1992-03-13
Granted: 1999-02-02
Abstract: A  thermostatically  controlled  mixing  valve  having  a modular  cartridge  mounted  in  a  housing.   The  cartridge comprises a tubular sleeve having rotatably disposed therein a hollow cylindrical housing.   The bottom of the cylindrical housing has a volume control valve plate attached against rotational movement thereto.  The volume control valve plate cooperates with a  fixed valve plate with which  it is  in surface-to-surface contact to control the volume  of water flowing into the cartridge.  The fixed valve plate is affixed against rotational movement to a nose piece which is fixedly attached  to  the bottom of  the  tubular sleeve.   An  inner housing is disposed within the hollow cylindrical housing and defines therewith cold and hot water inlet passageways which are in communication with a mixing chamber in the interior of the inner housing through hot and cold water supply openings.          A  thermostat  construction  responsive  to  the  mixed  water temperature is axially movably disposed in the mixing chamber and is operably connected to valving means adapted to open and close the hot water supply opening and cold water supply opening.   The  valving  means  comprise  a  cylinder  fixedly mounted on the top of the inner housing with the bottom of the cylinder and the top of the inner housing defining the hot water  supply  opening,  and  with  the  top  of  the  cylinder defining with an inner shoulder in the cylindrical housing the cold water supply opening, and a piston operably connected to said thermostat construction and axially slidably disposed in said cylinder.  Upward movement of the piston in the cylinder serves  to  close  off  the cold water  supply opening while downward   movement of the piston serves to close off the hot water  supply  opening. An  increase  in  the  mixed  water temperature in the mixing chamber results in axially downward movement of the thermostatic element with consequent downward movement of the piston thereby resulting in restriction or closure of the hot water supply opening. A decrease in the mixed water temperature  in the mixing chamber results  in axially upward movement  of  the  thermostatic  element  with consequent upward movement of the piston thereby resulting in restriction  or  closure of  the  cold  water  supply  opening thereby maintaining a preselected water temperature in the mixing chamber.

Title: Tooth assembly for a digger bucket
Inventor: SWICK CARL D
IPC: E02F9/28
Filed: 1992-03-16
Granted: 1996-07-23
Abstract: The invention is an improvement in a tooth assembly used with excavating and digging buckets such as those found in draglines, backhoes and the like.  Such tooth assemblies include a top portion (such as a wear cap), a nose protruding beyond the portion and a digging tip. The tip has high-hardness upper and lower exterior wear surfaces and a sharp-edged tip end for biting into earth, mineral and rock.  Either embodiment of the improved assembly involves mounting parts (a tip or tip and sleeve) directly on the nose.  In one improved assembly, a sleeve is interposed between the tip and the portion and includes high-hardness wear surfaces extending between tip and portion.  The tooth and sleeve cooperate to substantially entirely shroud the nose.  In another version having no sleeve, the tip includes high-hardness active digging surfaces extending substantially entirely rather than only partially between the portion and the tip end.  The tooth entirely shrouds the nose rather than being attached to the nose by a separate tip holder. With the improved arrangements, the tip and sleeve (or tip alone) comprise the primary replaceable parts and the nose is protected in that it is between high-hardness surfaces.

Title: Speech recognition apparatus having a speech coder outputting acoustic prototype ranks
Inventor: BAHL LALIT R
IPC: G10L19/00
Filed: 1992-07-16
Granted: 1996-08-06
Abstract: A speech coding and speech recognition apparatus.   The value of at least one feature of an utterance is measured over each of a series of successive time intervals to produce  a  series  of  feature  vector  signals. The closeness of the feature value of each feature vector signal  to  the  parameter  value  of  each  of  a  set  of prototype  vector  signals  is  determined  to  obtain prototype match scores for each vector signal and each prototype vector signal.  For each feature vector signal, first-rank and second-rank scores are associated with the prototype vector signals having the best and second best prototype match scores,  respectively.  For each feature vector signal, at least the identification value and the rank  score  of  the  first-ranked  and  second-ranked prototype vector signals are output as a coded utterance representation signal of the feature vector signal,  to produce  a  series  of  coded  utterance  representation signals.  For each of  a plurality of  speech units,  a probabilistic model has a plurality of model outputs, and output probabilities for each model output.  Each model output comprises the identification value of a prototype vector and a rank score.  For each speech unit,  a match score comprises an estimate of the probability that the probabilistic model of the speech unit would output a series  of  model  outputs  matching  a  reference  series comprising the identification value and rank score of at least  one prototype vector  from  each coded utterance representation signal in the series of coded utterance representation signals.
