Patent FR-695830-A (FR)
IPC: F16L21/02
Filed: 1930-05-19
Granted: 1930-12-22
Abstract: 354,866. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. May 21, 1930, No. 15678. Convention date, July 16,1929. [Class 38 (v).] In an " expansion " switch as described in Specification 354,890, with a vapour chamber having an upwardly - directed conduit 3 for the movable switch pin 4, the diameter of the conduit is at least 4 mm. greater than the diameter of the switch line. In the construction shown, the hollow cylindrical contact 5 in the explosion chamber 1 which contains liquid (for example, water) communicates through the pipe 7 with an auxiliary air vessel 6 which relieves the pressure in the chamber 1. This vessel is furnished with a valve 8 held down by a spring 9. If small powers are being dealt with by the switch the pressure produced does not raise the valve. For high powers, when the pressure necessary to cause effective arc-extinction (on expansion) has been reached by the action of the arc drawn between the contacts 4, 5, the valve is opened and excess pressure relieved. Both chambers contain liquid and the flow between them passes over the arc-foot and assists to extinguish the arc. After the break, the liquid levels adjust themselves by means of the small passages 10, 11. Any loss is made up for by the inverted bottle device 12.

Title: ASK modulator and communication device using the same
Inventor: SASABATA AKIHIRO
IPC: H04L27/04
Filed: 2000-04-28
Abstract: An ASK modulator can be operated with only a positive-voltage power source. A source-voltage switching circuit 21 that applies a positive voltage to the source of a FET 2 when a data signal 10 is at an L level in relation to the source of the FET is connected to the source of the FET which has a negative pinch-off voltage. Since the L level of the data signal can be set to 0 V, the ASK modulator can be configured only with the positive-voltage power source. This allows miniaturization and cost reduction.
Patent GB-2354611-A (GB)
Title: A transactional name service
Inventor: FREY JEFFREY A
IPC: G06F9/46
Filed: 2000-05-31
Abstract: One or more objects 1602 of a name server 1606 are managed as transactional objects, thereby providing a transactional name server. Atomic updates are provided in the name server by the addition of transactional semantics. The transactional semantics include making the objects of the name space managed objects and providing a local interface to a directory service that propagates a transactional context from the name server through a directory down to a resource manager. Binding and naming context classes support the same attributes, hence act as dual personalities for the same underlying directory data, allowing efficient one-hop lookup of objects that reside in a particular name server.

Title: A method and apparatus for transmitting data from an analogue modem to a digital modem through an analogue channel
Inventor: O'SULLIVAN BRIAN
IPC: H04L25/49
Filed: 2001-03-22
Abstract: A method for transmitting data through an analogue channel (4) from an analogue modem (2) to a digital modem (3) comprises encoding data inputted to the analogue modem (2). An encoder (6) encodes data inputted into the analogue modem (2) into corresponding constellation points (9) of a one-dimensional constellation (8). During initial handshaking a microprocessor (12) in the digital modem (3) computes the constellation points (9) of the constellation (8) so that mid points (15) between adjacent constellation points (9) coincide with mid points (14) between adjacent codec levels (10). The computed constellation points (9) of the constellation (8) are transmitted along with the value of the largest constellation point (9) and its corresponding codec level (10) to the analogue modem (2). By selecting the mid points (15) between the constellation points (9) to correspond with mid points (14) between adjacent codec levels (10) the noise margin is significantly enhanced.

Abstract: A folded substrate 35 e.g. a map or chart, has a stiffening treatment 40 such as aqueous coating, ink coating, other coating, spot lamination or varnish applied to it by spraying, laying as film or printing. The hinge 30 is formed by not applying the treatment, by applying a lesser (e.g. thinner) treatment or by applying a different treatment to a region of the base material. That region then forms a strip or band of untreated, less treated or differently treated base material that is more flexible than the treated.

Title: Control of flow into completion base pipe
Inventor: JOHNSON CRAIG D
IPC: E21B43/12
Filed: 2002-01-21
Abstract: In lateral wellbores, the flow rate from the formation into the completion base pipe 28 is not always equal along the length of the completion. There tend to be higher flow rates at the 'heel' of the lateral wellbore, than at the 'toe'. By varying the effective area of fluid communication between the completion and formation, the flow rate can be more evenly distributed. Thee methods to achieve this variation in effective area of fluid communication are disclosed. The sizes of holes 30 or the number of holes 30 in the completion base pipe may be graduated along the length of the pipe, with smaller or fewer holes at the heel of the lateral borehole. In another embodiment, the completion comprises a base pipe 28 having holes 30 in its wall, and a screen 34 that surrounds the base pipe 28. Splines 38 are located between the base pipe and the screen, and a rod 40 is selectively insertable between adjacent splines 38 to selectively cover the holes 30 located an the base pipe 28 between the adjacent splines 38. In a third embodiment, a sleeve 44 having openings 48 in its wall is rotatably connected to the base pipe 28, such that rotation of the sleeve enables the alignment and misalignment of the holes 30 and openings 48.

A group of relay channels electrically connects the first group of contacts with the second group of contacts in a state where the rear converter is mounted between the camera body and the photographing lens. A memory (321) in the rear converter stores rear converter data and a controller (311) reads the rear converter data from the memory. The memory and the controller have a function to send the rear converter data to the camera body while the camera body and the photographing lens communicate with each other via the first group of contacts, the second group of contacts, and the group of relay channels.

Title: Sending location reports from a mobile transceiver at intervals inversely dependent on the distance from a target zone or cell
Inventor: WATSON JOHN
IPC: H04W60/04
Filed: 2002-04-15
Abstract: In a mobile telecommunications system, such as a 2G GSM or 3G UMTS network, boundary crossing routeing area update signals (RAUs) are produced as a selected mobile enters each of a plurality of routeing areas (RA1,RA2,RA3) to a target zone in the form of a cell (12) within a particular routeing area (RA3). As the terminal moves though each routeing area A towards the routeing area (RA3) in which the target zone (12) is located, it is arranged to produce periodic routeing area update signals (PRAUs) at a reporting frequency which increases as the terminal approaches the target zone C.

Title: A composite shaft assembly providing a surface for forming joints
Inventor: MYERS CHRISTOPHER ALAN
IPC: F16C3/02
Filed: 2002-07-11
Abstract: The present invention relates to an assembly that provides metallic ends to a composite shaft and a method Of fabricating such an assembly. The composite shaft 14 is preferably comprised of reinforced fibres. A metallic inner sleeve 12 is positioned in the cavity of one end of the shaft. A metallic outer sleeve 16 is positioned around the end of the shaft having the inner sleeve therein. The outer sleeve may include structural features such as small protrusions that ensure a stable connection between the sleeve and the shaft. The sleeves are compressibly forced onto the shaft, thereby forming the assembly. Both sleeves are metallic, and therefore provide a surface onto which weld joints can be formed. A preferred method of assembly includes the steps of expanding the inner sleeve and compressing the outer sleeve against the shaft.
