Title: An automatic/manual control device with emergency override
Inventor: LEE JIN HAN
IPC: F02D29/04
Filed: 1996-11-13
Abstract: A control device for a hydraulic motor of a construction vehicle operates, in automatic control mode, proportional control valves 2a and 2b in response to control signals from a controller 4, thereby allowing a pilot pressure which is supplied by a pilot pump Pp via shuttle valves 3a and 3b to be fed to a spool of a directional control valve V. The pilot pressure moves the spool in either direction and starts a motor M which is continually controlled by the pilot pressure being fed back by a pressure sensor 5 to the controller 4. In manual mode control pedals D are activated by an operator which produces a pilot pressure that is applied to pressure switches 6a, 6b so that an output signal is relayed to the controller 4, thereby providing priority over the automatic mode in case, for example, of an emergency. The pilot pressure is also supplied, via shuttle valves 3a and 3b, to the spool of the directional control valve V, thus starting the motor M. Data concerning the operation of the pedals D is saved in a memory of the controller 4 by turning on a function select switch in order to activate a data storing function which initiates the storing of the output signals from the switches 6a, 6b and the pilot pressure from sensor 5. The operation of pedals D is automatically repeated in accordance with the stored data when the function select switch is put into repeating mode.

Title: Synthesiser
Inventor: COLEMAN MARK ANTHONY
IPC: H04B1/04
Filed: 1997-03-12
Abstract: A synthesiser is arranged to generate frequency hopping signals which change frequency without a settling time. The arrangement comprises high-band and low-band signal generators 5, 6 which are alternatively multiplied with an intermediate frequency signal using a mixer 3 acting in combination with a selection switch 4. By arranging for the frequency of the signals generated by the high-band and low-band signal generators in combination with the intermediate frequency to generate mirror frequency signals within a common frequency bandwidth, the synthesiser may be arranged to change frequencies without a requirement for a settling time, and without the frequency of the high-band and low-band signal generators having substantially the same frequency contemporaneously. The synthesiser may form part of a DECT (Digital Enhanced Cordless Telephone) system. The IF signal may be FSK or PSK modulated.

Title: Joining jig
Inventor: ISHII KANJI
IPC: B23P11/00
Filed: 1997-06-04
Abstract: In a workpiece joining method an end portion of a bolt shaft 1 is inserted into each hole 3a of at least one workpiece 3, and a sleeve 2 is placed onto an end of each bolt shaft. Then, an upper die 5 is lowered toward the workpiece supported on a lower die 4 so that while the workpiece is being pressed toward base end portions of the bolt shafts 1, a tightening portion 6b of each nose 6 provided on the upper die 5 draws the outer wall of the corresponding sleeve 2, thus tightening the sleeves. The tightened portion of each sleeve progressively enters a relief portion 6c formed above the tightening portion. The thrust of the noses 6 does not act directly on the bolt shafts in the direction of their axes, so that the joining jig can apply a tightening force without being restricted by the strength of the bolt shafts.
Patent GB-2315179-A (GB)
Title: Collision avoidance system
Inventor: KINOSHITA MASAHIRO
IPC: B60W30/16
Filed: 1997-07-09
Abstract: In a vehicular drive assist system for warning a driver to pay attention to a preceding vehicle running ahead when a vehicle comes close to the preceding vehicle and the distance (L s ) between these two vehicles becomes smaller than a safe inter-vehicle distance (L c1 , L c2 ), this safe inter-vehicle distance is automatically established in two stages according to traffic conditions. One stage is where the road is empty and another is where the road is crowded. Since the safe inter-vehicle distance at the crowded condition is established to be a smaller value than the one at the empty condition, when road is crowded, due to the shortened safe inter-vehicle distance, a warning is prevented from being issued so frequently.

Title: Downhole valve
Inventor: HUBER KLAUS B
IPC: E21B34/06
Filed: 1998-01-23
Abstract: A downhole valve 20 is disclosed for use in a tubing-conveyed string of tools in a well bore, constructed to be actuated to open under pressure forces by dropping a drop bar from the well surface through the tubing. The valve, deployed in the well in a closed condition, has a frangible member 34 arranged to be broken by the drop bar to enable the valve to open. The valve opens under well pressure forces when well pressure exceeds tubing pressure, and opens under tubing pressure forces when tubing pressure exceeds or substantially equals well pressure. The valve is particularly useful when opened in conjunction with the detonation of a perforating gun for overbalanced or underbalanced well perforation. The valve 20 has ports 38 closed by sleeve 42. A floating piston is located between valve housing 40b and sleeve 42. Chamber 50 contains an incompressible fluid which prevents downward movement of sleeve 42 when frangible member 34 is intact. When frangible member is broken fluid can escape from chamber 50 to allow sleeve to move downwardly under the action of (a) tubing pressure acting via ports 72 on shoulder 66 of sleeve when tubing pressure exceeds, or is equal to, well pressure; or (b) well pressure acting via ports 38 on upper end of piston 64 when well pressure exceeds tubing pressure.

Title: Drill pipe/casing protector assembly
Inventor: KRUEGER R ERNST
IPC: E21B17/10
Filed: 1996-10-10
Abstract: A drill pipe/casing protector assembly (18) for an underground drilling system comprises a well bore in an underground formation, a fixed tubular casing (16) installed in the well bore (14), a rotary drill pipe (12) extending through the casing (16) and having an O.D. spaced from an I.D. of casing (or well bore) during normal drilling operation, and a protective sleeve (18) mounted around the drill pipe and spaced from the I.D. of the casing, and upper and lower thrust bearings (22, 24) affixed to the drill pipe above, and below the sleeve to retain the sleeve in a fixed axial position on the drill pipe. The sleeve (18) contacts the I.D. of the casing when the drill pipe (12) deflects off-center to protect the casing from contact with the drill pipe or its tool joints during rotation of the drill pipe. Axial grooves (26) in an I.D. wall of the sleeve allow fluid under pressure to circulate through a space formed between the I.D. of the sleeve (18) and the O.D. of the drill pipe. Generally fiat bearing surface regions (32) on the I.D. wall of the sleeve between adjacent grooves (26) are arranged in a polygon configuration for tangentially contacting the O.D. of the drill pipe around the sleeve I.D. The sleeve (18) separates from the O.D. of the drill pipe upon circulation of a fluid film under pressure between the sleeve (18) and the drill pipe (12) to produce a fluid bearing effect with reduced frictional drag. End slots at the top and the bottom annular end walls of the sleeve provide enhanced fluid bearing effects in the clearance regions between the sleeve and the adjacent thrust bearings (22, 24).

Title: Misfire state discrimination in an internal combustion engine
Inventor: HATANO GAKU
IPC: F02D45/00
Filed: 1998-04-03
Abstract: A misfire state discrimination system of an internal combustion engine (10), which determines the occurrence of misfire under engine operating conditions that make misfire determination possible and counts the number of misfires to compare with a reference value. The misfire state of the engine is discriminated based on the result of comparison. In the system, when the engine operation moves from the conditions that makes the misfire determination possible, the count is saved and is counted up from the count when the engine operation returns to the condition. The saved count is also retained when the engine is stopped. Similarly, the number of combustions during which the determination of misfire occurrence is made is counted and the count is saved. This arrangement enables a rapid and accurate discrimination of the misfire state of the engine.
