Title: Strain measurement system
Inventor: SHARPE BRIAN ALLAN JOHN
IPC: G01M13/02
Filed: 1994-01-14
Abstract: A strain measurement system comprises a wheatstone bridge 20 having strain gauge arms 21 - 24 adhesively bonded to a surface of a component e.g. a power drive shaft (51, Figure 3). A potential divider for monitoring temperature comprises low and high stability resistors 34, 35 and is co-mounted with the bridge across supply lines 25, 26. The output of the bridge is connected by lines 36, 37 with an application specific integrated circuit (ASIC) 38. A line 39 connects the ASIC 38 and a junction of the resistors 34, 35. The ASIC includes an analogue switch 40 for switching between a strain related bridge output signal on line 36 and a temperature related signal on line 39. The signals are fed via an operational amplifier 41 to an A/D converter 42. Digital signals are passed from the converter to an algorithmic operator 43 which accesses an external EEPROM 44. The EEPROM 44 holds a matrix look-up table storing data obtained by calibration of the system over desired strain and temperature ranges. The algorithmic operator 43 reads down correction data and uses interpolation logic to calculate a strain value which is corrected for zero offset, zero drift with temperature and span drift with temperature. The corrected strain value is passed to a digital frequency synthesizer 45 which produces a frequency signal on line 46. If desired a visual or audio warning is given if a predetermined strain level is exceeded. Calibration data is input to the EEPROM 44 via lines 89, 90. <IMAGE>

Title: Data radio equipment and method of controlling a radio and a radio modem
Inventor: SERFATY SALOMON
IPC: H04W88/02
Filed: 1994-11-26
Abstract: Data radio equipment has a radio 14 operable on a radio system, a radio modem 12 connected to the radio 14, and data terminal equipment 10 connected to the radio modem 12 via a port (130, Fig.4). A translating device 122 in the radio modem 12 receives signals from the data terminal equipment 10 via the port (130) and translates at least a part of a received modem control command into a radio command. A control element 126 in modem 12 is coupled to the translating device 122 and to the radio 14, for controlling the radio in response to the radio command to communicate with the radio system. The prior art requirement for the data terminal equipment 10 to have both a first port (26, Fig. 1) coupled to the modem and a second port (18) coupled to control the radio 14 is thus avoided. Data may be communicated between data terminal equipment 10 and the radio 14, between the radio 14 and a selected one of second radio devices 34, 36 and between the second radio device and a gateway 42, where extension parts of the modem command define the identity of the second radio device and one or more outputs 44, 46, 48, 52, 54, 56 of the gateway 42. The gateway outputs may be coupled to local and remote host computers 50, 72. <IMAGE>

Title: Handling erroneous data frames on a multi-hop communication link
Inventor: HUGHES JOHN
IPC: H04L1/00
Filed: 1995-11-03
Abstract: At an intermediate hop site (300) Fig.3, (not shown), in a multi-hop communication link between a transmitter and receiver, a received transmission is processed to handle erroneous data frames. A data stream is recovered from the transmission which includes one or more data frames, each having corresponding error detection information (410). When a particular data frame is detected as being erroneous, based at least in part on an evaluation of the corresponding error detection information (420), the data stream is modified to include an indicator representing that the particular frame does not contain valid data (430), and the data stream is retransmitted (440). Thus bad frame indication is performed at the intermediate station(s) and bad frame substitution (mitigation) is left for the receiver, (after checking if the receiver is capable of receiving such indication).

Title: Drinks dispensing apparatus
Inventor: SWINDLEHURST ROBERT GEORGE
IPC: B67D1/02
Filed: 1996-10-23
Abstract: Drinks dispensing apparatus comprises a storage cask 1 for beer to be dispensed from a dispensing head 2 by a hand operated lever 4. The cask is fitted with a peg 6 above the level of beer in the cask. The peg operates as a one-way pressure-operated check valve that is biased closed when the pressure of carbon dioxide in the container is greater than atmospheric pressure and is forced open if the carbon dioxide pressure in the container is less than atmospheric to allow air to pass into the container. The invention prevents carbon dioxide released from the surface of the beer from escaping form the cask and thereby affecting the quality of the beer. Moreover, the peg allows air to pass into the cask when beer is being dispensed to prevent a partial vacuum being created.

Title: Computer-based information access method and apparatus to permit sql-based manipulation of programming language-specific data files
Inventor: BRADLEY JOHN
IPC: G06F17/30
Filed: 1995-05-12
Abstract: A method and apparatus that permits creation, reading and modification of 3GL application programs by SQL requests. A catalog is created by selecting source programs from 3GL application data for which file definitions are to be extracted, identifying specific files within the selected source programs to be processed, extracting appropriate schema from the selected files, and recording the appropriate schema in a catalog. Once the 3GL-specific data schema contained in the application source has been extracted and stored in the catalog, the relational database which is to be based upon the data represented by the 3GL schema is defined and stored in the system catalog so that tables in the relational database may be accessed by a runtime SQL database engine. Further, both 3GL data and relational database data may be modified and maintained with a single tool set. After the catalog is created, the invention uses the catalog to process SQL requests in order to access the relational database representation of the 3GL data by parsing the SQL query request, generating a set of possible execution plans for manipulating the relational form of the data, selecting an optimal plan based upon information provided from the system catalog, and executing the plan by servicing the SQL request for relational data from the underlying 3GL data files described in the system catalog.

Title: Method for indicating the generation of secondary electron charge within a CRT
Inventor: KATO HIDEO
IPC: G01R31/25
Filed: 1997-02-13
Abstract: A method is disclosed for detecting the operation of an electron beam during an ageing process, which is employed to indicate that the correct conditions for the generation of secondary electron charge within a cathode ray tube (CRT) 10 had been achieved. The method comprises deflecting an electron beam onto the funnel 14 of the CRT and comparing a temperature measurement, taken for a predetermined portion of the CRT, with a reference temperature value. The presence of an electron beam is detected when the measured temperature is greater than or equal to the reference temperature value. This provides an indication that secondary electron charge may have been developed on the inner surface of the CRT. A failure in the electron beam operation is detected when the temperature value is below the reference temperature and this indicates the possible failure to develop secondary electron charge on the inner surface of the CRT. The ageing process may involve an electron beam raster scan for two hours providing a screen brightness of 60cd/sq.m, a period at an ambient temperature of 40 degrees Celsius and a cooling period in an ambient temperature of 25 degrees Celsius. The temperature measurement may be performed, using a non-contact thermometer, 20 minutes or more into the cooling period.
