Title: Drilling tool
Inventor: KAMMERER KARL
IPC: E21B10/633
Filed: 2002-12-28
Abstract: The invention relates to a drilling tool comprising a drill bit with an annular base body that can be fixed to a hollow cylindrical drill pipe. The base body has tool recesses, which are distributed around the circumference of the side facing away from the drill pipe and which hold interchangeable cutting teeth, the tool head of said teeth projecting in an axial direction above the base body. A shaft, which is mounted in a shaft cavity of the tool recess, is coupled to the tool head. The aim of the invention is to obtain an optimised tool in terms of technology and resistance to wear. To achieve this, the shaft is mounted in an insertion channel of the shaft cavity, the insertion cavity terminates in a opening, which accommodates a nut, the shaft has a threaded section that projects into the opening and is screwed into the nut and the cutting tooth is held in a prestressed manner against one or more supporting surfaces of the tool recess.

Title: A networked method for the control and monitoring of internet messages by analysis using a smart algorithm and a designated dictionary.
Inventor: ROBERTS DANIEL
IPC: G06Q10/00
Filed: 2006-04-20
Abstract: Method for exchanging permissible information between a sender and recipient that are connected to a data network through a hosting website. Textual information is exchanged between the sender and recipient using an accessible electronic dictionary that contains a set of permissible words, excluding combinations of characters that are not permitted by the hosting website. An algorithm may also be used to exclude words under certain circumstances. When a message is composed by the sender and sent to a recipient, it is first redirected to the hosting website. Only when this has verified that the words used appear in the dictionary of permissible words, is it directed to the recipient. Otherwise, the outgoing message is rejected and the sender notified that the message comprises non-permissible words. When permitted by the website, for example after a payment is received, the sender and recipient are allowed to exchange messages using any words.

Title: Method and apparatus for manufacturing orthodontic appliances
Inventor: MCCANCE ANDREW
IPC: A61C9/00
Filed: 2006-12-28
Abstract: The invention provides a method of manufacturing a series of tooth positioners for incrementally repositioning one or more teeth of a patient from an initial configuration to a final configuration via one or more intermediate configurations. The method uses a composite model of the patient's teeth in the initial configuration, the composite model having a base and one or more discrete model teeth. Each model tooth includes a crown portion and a root portion and is mounted on the base in a tooth mounting portion of the base formed from a mounting material in which the root portion can be imbedded and retained in position but which can allow movement of the root portion through the tooth mounting portion upon application of a force to the crown portion of the model tooth. In the method, the position of one or more of the model teeth is changed to reconfigure the composite model to a first intermediate configuration. A negative impression of the first intermediate tooth configuration is then made. The position of one or more of the model teeth in the mounting portion of the base is then changed again to reconfigure the composite model to a second intermediate or a final configuration. A second or final impression of the second intermediate or final tooth configuration is then produced. The impressions taken from the model can be used to make the series of positioners.

Title: Multi-channel digital to analog (D/A) conversion
Inventor: LEE YING LAU
IPC: H03M1/66
Filed: 2006-06-02
Abstract: A multi-channel digital-to-analog (D/A) conversion system that can produce an analog output (210) from a digital signal (201) using N D/A converters (C1-CN), each with 1/N of the resolution of a single D/A converter used to perform the same D/A conversion. A data sample (Din) of the digital signal (201) is decomposed into N data sub-samples (D1-DN). The sum of the values of the data sub-samples (D1-DN) is equal to the value of the data sample (Din), while the normalized range of the value of the data sample Din is greater than the normalized range of the value of each data sub-sample (D1-DN). Each D/A converter (C1-CN) receives a respective one of the data sub-samples (D1-DN), and generates a respective one of a plurality of analog component outputs (A1-AN) singly or jointly with at least one of the other D/A converters (C1-CN). The analog output (210) is produced by additively combining the plurality of analog component outputs (A1-AN).

Title: Switchgear with busbars arranged to induce cooling air flow
Inventor: HALL KEITH ANTHONY
IPC: H02B1/20
Filed: 2007-12-10
Abstract: An electrical switchgear apparatus 11 includes a plurality of spaced-apart busbars 64, 66 of which certain ones 66 are configured to induce a temperature reducing flow of air 6 between the busbars. Certain ones of the busbars 66 may be inclined at an angle with respect to the vertical, which creates a natural convection current of cooling air between the busbars as they become hot. The cooling air is drawn into the switchgear enclosure and expelled from it through vents to the surroundings. The orientation of the busbars ensures that an adequate cool air flow from the vents passes around the busbars. The busbars therefore can be cooled without fans or other means of forced air flow.

Title: Bypassing a faulty link in a multi-path network
Inventor: BEECROFT JON
IPC: H04L69/40
Filed: 2008-08-14
Abstract: A method of managing faults in a multi path network is disclosed. In one embodiment a multi-path network for use in a bridge, switch, router, hub or the like, the multi-path network includes a plurality of network ports; a plurality of network elements 18; and a plurality of network links 17 interconnecting the network elements and the network ports for transporting data packets, each network element including a fault monitor for detecting faults on the network links to which the network element is connected, a plurality of dynamically selectable output ports and output port selection mechanism and each network element being adapted to communicate the existence of a fault back to one or more other network elements via which network elements the faulty network link can be bypassed, and each network element being adapted to update its output port selection mechanism when communication of the existence of a fault is received so that only output ports which ensure the faulty network link is bypassed are dynamically selectable. In one embodiment a fault is triggered by detection of a received corrupted data packet (e.g. from a CRC check) and the existence of the fault is communicated back along the path followed by that data packet across the network prior to its corruption, for example using an error warning in a delivery acknowledgement message. The fault communication may include identification of one other network element in the path which is required to update its output port selection register to bypass the faulty network link, alternatively the fault communication may include identification of the element that detected the fault and the other network elements are required to determine whether they need to update their output port selection registers 12 on the basis of the network element that issued the fault communication.
