Title: Hanger suspension system
Inventor: TURNER EDWIN C
IPC: E21B33/043
Filed: 1996-05-20
Abstract: A hanger suspension system 60 includes an inner casing hanger 90 having an outer circumferential surface with at least three sets of at least three longitudinally spaced outwardly projecting load bearing members 100,102,104 azimuthally spaced about the outer circumferential surface and separated by linear flow passages. A hanger assembly 125 is positioned on each set of bearing members and is axially slidable on the outer circumferential surface of the hanger. Each hanger assembly includes a plurality of longitudinally spaced arcuate members 132,134,136 having inwardly extending load bearing shoulders for engaging the load bearing members of the inner hanger. The hanger suspension system also includes an outer head (not shown) having a non-restrictive bore with annular recesses which include load bearing surfaces and camming surfaces. The arcuate members 132,134,136 of the hanger assembly include outwardly extending load bearing shoulders for engaging the load bearing surfaces of the outer head and outwardly extending camming shoulders for engaging the camming surfaces in the annular recesses of the outer head. The hanger assembly also includes a trigger member 170 for releasing the bearing member upon alignment with the outer head and includes a deformable alignment tang for locating the recesses in the outer head. The load bearing members on the inner hanger bear against the arcuate members so as to maintain the arcuate members in engagement with the load bearing surfaces of the outer head. The suspension of the inner hanger within the outer hanger is repeatable so as to allow the reciprocation of the inner casing string within the outer casing string during the cementing operation.

Title: Safeguarding hard drive data
Inventor: KONG WON-KEUN
IPC: G06F1/00
Filed: 1996-07-25
Abstract: The computer has a security potion which arranges that the computer may only be initialized if a correct password is supplied and if the hard drive is the same as that which was originally installed together with the security portion. The methods for installing and removing the security portion involve the manipulation of the boot code on the hard drive. The security portion can inhibit disk control commands from writing to the boot sector on the hard disk to guard against circumvention of the security system. Data written from the hard drive to a floppy drive can be encrypted and the system can be arranged so that data is read from the floppy to the hard drive only if it was previously encrypted using the same scheme.

Title: An in line fuel pump control rack damper
Inventor: TONKS JOHN PETER
IPC: F02M63/00
Filed: 1997-02-06
Abstract: An in line fuel pump 22 for a diesel engine has a rack 30 controlling fuel valves 28, which are rotary. Movement of the rack 30 toward the throttle open position is damped by a hydraulic shock absorber 44. The control rack is able to return to its closed position unhindered. This prevents the valves 28 opening too suddenly thus allowing engine speed to pick up in order to fully utilise the fuel being delivered and thereby reducing emissions, engine wear and carbon deposits and improving fuel efficiency.

Title: Measuring earth formation pressure
Inventor: AUZERAIS FRANCOIS M
IPC: E21B47/06
Filed: 1997-04-10
Abstract: An earth formation tool measures pressure from within a borehole. A portion of the borehole wall is isolated from surrounding borehole fluids by placing a chamber 24 of a borehole tool against the borehole wall. The chamber comprises a recess in an exterior surface of a borehole tool. Mudcake 20a present on the isolated portion of the borehole wall is disintegrated by an ultrasonic transducer 34 within the chamber. In this manner, there is no resistance to fluid flow from the chamber to the formation 12. A pressure gauge 30 measures pressure of the chamber to indicate pressure of the earth formation. This approach can be used to make moving or stationary measurements of earth formation pressure.

Abstract: A transmitting/receiving apparatus comprises a means for transmitting phase modulated signals and a receiver having a waveform shaper and a discriminator for determining the presence of binary 0 and 1 in the received signal. A unit period of time T is defined as representing a 0 and some integer multiple of this unit period to represent a 1. A leader code is provided and defines a reference bit of duration 2T. A high and subsequent low level of the signal are said to define a unit bit, measurement of the period of two successive unit bits is used to discriminate between 0 and 1. The above apparatus may be used to transmit inclination data of a remote detector with respect to a source from the detector back to a base computer, for example to move a cursor on a display screen. Alternatively a signal group of the data may be inverted and the signal groups regularly repeated. The coordinates of a source relative to a detector or vice versa may also be transmitted.

IPC: G06F13/00
Filed: 1998-08-06
Abstract: Methods and systems are provided for communicating with a web browser (10) executing on a remote/mobile processing system (5) which is temporarily and intermittently connected to a second computer. Requests e.g. on HTML forms from the web browser (10) to a server application accessible to the second computer are stored in a persistent request queue (32) at the remote/mobile processing system (5). An interim response is provided to the web browser (10) in response to the request from the client application. The stored request may be recalled to allow user modification of the stored request prior to the request being provided to the second computer (6) for transmission to the server application. Thus a patient admission form could be edited to correct errors or be resubmitted with new data for a different patient. By storing requests in a request queue and providing an interim response to the web browser asynchronous operation of the web browser is achieved.

Title: Battery charger start up timer for fully charged battery
Inventor: HARDIE JONATHAN OWEN
IPC: H02J7/10
Filed: 1999-02-11
Abstract: A battery charger start up timer operates at the start of charging to maintain an initial rate of charging for a period during which a charge termination system is disabled so as to prevent changes in battery parameters during initial charging giving a false indication of a fully charged battery. However, this may cause damage to a battery which is in an almost fully charged state when initially connected to the charger. The start up timer therefore provides an initial rate of charging for a fixed first period and continues the initial rate of charging for a consecutive secondary period within which secondary period charging is terminated in response to an indication of a fully charged battery derived from a series of averaged battery temperature measurements. The second derivative of temperature is calculated 34 at predetermined intervals and a counter is incremented 35 if this derivative is positive. A positive second derivative over a number of intervals during initial charging is indicative of a fully charged battery. If the count reaches a value of four, then the charge termination system is enabled to stop charging. The measurement intervals may be such that the fixed first period has a duration of two and one half minutes. The secondary period is terminated after ten minutes by a timer if the count has not reached a value of four, the charge termination system being then enabled to terminate charging when full charge is detected during subsequent charging of the battery. The charger does not allow charging to commence unless the battery is initially within certain charge limits 32, determined by comparison of battery voltage with a threshold voltage, comparison of battery temperature with minimum and maximum values, and by requiring the battery temperature to be within plus or minus 10{C of ambient temperature. Charging is also discontinued 36 during the start up timer period if these limits are exceeded. The arrangement may be used to control charging of a battery in a mobile phone
