Title: Gear with bearing arrangement
Inventor: MAATTA JOUNI
IPC: F16H57/021

Granted: 2005-08-02
Abstract: The invention concerns a gear, which comprises a shaft (12) and on it a gearwheel (13), which is in engagement with a gearwheel (17) mounted on a shaft (16). The shaft (16) comprises bearings (18 and 19) at both sides of the gearwheel (17) between the frame (11) and the shaft (16). The gear comprises a spring/springs (23a1, 23a2...), which is/are fitted to act with a force (F) upon the outer race (18') of the rolling members (20a1, 20a2...) of the bearing (18). Between the circumferential face (C1) of the outer race (18') and the gear (10) frame (11) or a connected part there is a glide fitting. In this connection the force effect is transferred further through the rolling members (20a1, 20a2...) of the bearing (18) to the inner race (18") of the bearing (18) and further to the bearing means (19) placed at the opposite side of the gearwheel (17). In this way the play in the bearings (18 and 19) placed at both sides of the gearwheel (17), between the rolling members (20a1, 20a2...) and the bearing (18, 19) races (18', 18"; 19', 19"), is eliminated.

Abstract: A multiple network protocol encoder/decoder comprising a network protocol layer (101), data handler (102), O.S. State machine (104), and memory manager (103) state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine (101) which decodes network protocols such as TCP, IP, user Data Protocol (UDP), PPP, and Raw Socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler (102) which consists of data state machines (104) that decode data formats such as email, graphics, Hypertext Transfer Protocol (HTTP), Java, and Hypertext Markup Language (HTML). Each data state machine (104) reacts accordingly to the pertinent data, and any data that are required by more than one data state machine (104) is provided to each state machine concurrently, and any data required more than once by a specific data state machine, are placed in a specific memory location (206) with a pointer designating such data; thereby ensuring minimal memory usage.  Resulting display data are immediately passed to a display controller (205).  Any outgoing network packets are created by the data state machines and passed through the network protocol state machine which adds header information and forwards the resulting network packet via a transport level mechanism.

Title: Network mute feature in wireless telecommunications systems
Inventor: WIERZBICKI ALEX LAWRENCE
IPC: H04M3/56
Filed: 1999-07-29
Granted: 2003-03-25
Abstract: A network mute feature deployed in a wireless telecommunications system allows a mobile user to eliminate ambient environmental and wireless transmission noise. Upon activation of the network mute feature, a voice path interconnecting the mobile unit to a party served by the public switched telephone network (PSTN) is opened. A portion of the open voice path is subsequently interconnected to a noise generator so that the PSTN party hears unobtrusive background noise indicating that the mobile user is still "on the line" and can hear transmissions by the party. The PSTN party, however, cannot hear noises associated with mobile user's environment or wireless transmission while the network mute feature is activated.  Advantageously, the network mute feature enhances the ability of mobile users to participate in calls in which the quality of transmission (e.g., a conference call) is important.

Title: Permeability or fluid mobility reduction treatment for a hydrocarbon-bearing formation using a dual molecular weight polymer gel
Inventor: SYDANSK ROBERT D
IPC: C09K8/512
Filed: 1999-09-22
Granted: 2007-11-06
Abstract: A process is provided for reducing the permeability of or fluid mobility within a high-temperature treatment region in or proximate to a hydrocarbon-- bearing formation below an earthen surface penetrated by a well bore. The process is initiated by preparing a gelation solution at the earthen surface which includes a base loading of a high molecular weight acrylamide polymer, an additive loading of a low molecular weight acrylamide polymer, a crosslinking agent, and an aqueous solvent. The crosslinking agent is preferably a chromium(III) complex having one or more chromium(III) cations and one or more carboxylate anions. The resulting gelation solution is injected into the well bore and displaced into the treatment region where it is gelled in situ to form a gel which substantially reduces the permeability of or fluid mobility within the treatment region.

Abstract: The present invention provides a method for reducing power consumption in a satellite downlink transmitter (100).      The method includes the steps of defining a frame structure for use on a downlink, and further defining a traffic body (218, 220, 222) and an overhead body (212, 214, 216) in the frame structure (202, 204, 206). The method further determines the amount of time required to transmit the traffic body ("the traffic transmit time") and the amount of time required to transmit the overhead body ("the overhead transmit time"). Subsequently, the method activates a transmitter for the overhead transmit time to transmit the overhead body (212, 214, 216) including the synchronization information. Thus, a ground station may acquire synchronization and lock onto the downlink. The method then, however, selectively deactivates the transmitter for the traffic transmit time. The method thereby transmits the overhead body (212, 214, 216) in every frame (202, 204, 206), but may save power by not transmitting the traffic body (218, 220, 222) of the frame.

Granted: 2004-07-20
Abstract: A recording head comprises a plurality of recording elements for performing recording; a driving circuit for driving the plurality of recording elements; and a predetermined voltage generating circuit for generating a predetermined voltage to be applied to the plurality of recording elements from voltage supplied from outside. With the head thus structured, a desired voltage is generated in the interior of the head by use of the predetermined voltage generating circuit for performing recording, thus making it possible to prevent the voltage drop which may take place if the voltage is supplied from outside through a cable, as well as to prevent the durability of the heat generating elements from being damaged due to noises. It also becomes possible to set the voltage to be applied to the recording elements at an optimal value corresponding to the discharge voltage, hence stabilizing ink discharges efficiently.

Abstract: An articulated four wheel drive work vehicle is provided with a front axle having a front differential and a rear axle having a rear differential. Both differentials are provided with hydraulically operated differential locks that are coupled to respective solenoid control valves. The solenoid control valves are coupled to a microprocessor. The microprocessor has a manual mode in which the differential locks are controlled by a foot pedal in the operators cab and an automatic mode in which the microprocessor controls the differential locks in response to speed signals from the axles and the transmission. The microprocessor calculates a predicted axle speed based on the transmission output speed signal received by a transmission speed sensor. The microprocessor then compares this signal to the actual axle speed signals received from axle speed sensors and triggers the respective solenoid valve if the difference is greater than a programmed amount. An articulation angle sensor sends an articulation angle signal to the microprocessor. If the articulation is greater than a programmed amount the solenoid locks are released.
