Title: Angular motion detector for a torque wrench
Inventor: CRANE DAVID OGILVIE
IPC: G01L5/24
Filed: 1992-12-24
Abstract: An angular motion detector, of particular relevance in breakaway point detection, includes a flywheel 1 rotatably mounted on a spindle 2 on a torque wrench 3. The flywheel 1 is provided with one or more indicia 7, which are detectable by a sensor 8 situated on the object whose angular motion is to be analysed. The sensor 8 is connected to a microprocessor 9. In use the flywheel 1 is rotated manually about the spindle 2 so that the regular detection of the indicia 7 by the sensor 8 causes a train of pulses to be sent to the microprocessor 9. Angular movement of the object, and consequently of the sensor 8, causes a disruption of the pulse train which can be analysed to provide information relating to the time of first movement and the magnitude of the angle moved. <IMAGE>

Title: Deformation sensor for vehicle side impact protection system
Inventor: MEYER MICHAEL
IPC: B60R21/01
Filed: 1994-07-07
Abstract: The sensor is composed of two pressure-sensitive signal elements 4, 5, arranged in parallel and one behind the other, so that the deformation speed can be determined from the time sequence of the sensor signals. The signal element 4 is integrated into a protective strip 3 of the vehicle mounted on the outside of the door shell 1, and the second element 5 may be fastened to the shell or to the strip 3 (figure 3). A reinforcing profile 2 is provided within the door shell 1. On impact, the elements 3.1 deform and the sensor 4 moves nearer the shell 1, the deformation speed thus being measured. If the impact is sufficiently hard the second sensor 5 is activated by impact against the profile 2. <IMAGE>

Patent GB-2281013-A (GB)
Title: Portable radio communication apparatus
Inventor: MURAKAMI TAKASHI
IPC: H04B1/38
Filed: 1994-07-20
Abstract: In a portable radio communication apparatus selectively operable with an internal antenna 12 or an external antenna 14, a control signal is fed to a control signal input terminal 24 when the external antenna is connected to an external antenna terminal 14a. The control signal causes an antenna switch 18 to connect the external antenna to a radio section 16 in place of the internal antenna. A control switch 32 is connected between the control signal input terminal and the antenna switch and turned on when the internal antenna is retracted or turn off when it is extended, so that the internal antenna may be used even when the external antenna is connected. <IMAGE>

Title: Print information processing
Inventor: OH YOUNG-DALL
IPC: B41J2/44
Filed: 1996-02-28
Abstract: A method of processing print information of a page print apparatus is disclosed. Firstly, print data is stored in a memory. Next, previously calculated first and second variables representative of the cumulative ratio of black pixels to total pixels and the cumulative total number of pages printed are retrieved. The first and second variables are recalculated from the variable values retrieved and the stored print data to provide recalculated variable values representative of the current cumulative ratio of black pixels to total pixels and the current cumulative total number of pages printed. The recalculated variables are then stored. These values can be used to allow a user to predict with greater accuracy the time at which a toner cartridge must be replaced. Third and fourth variables based on daily averages and fifth and sixth variables based on monthly averages can also be used.

Abstract: A system for sealing a wellhead comprises: a wellhead housing (11) for connecting to a well string casing, the wellhead housing being annularly disposed about a central axis (26) and having a primary sealing surface (12); a reference surface (14) extending below the primary sealing surface; and a secondary sealing surface (18) extending below the reference surface. The reference surface may be used as a guide in manufacturing the primary and secondary sealing surfaces. A wellhead connector (21) is annularly disposed about the central axis and has a connector sealing surface (36). A secondary seal ring (15) is annularly disposed about the central axis (26) and has a ring seal surface (15e) for sealing contact with the connector sealing surface; and an extension (15b) extending below the ring seal surface and having disposed thereon a sealing land (15a) for sealing contact with the wellhead housing. Vertical compressive forces between the housing (11) and connector (21) generate a twisting moment in the ring (15) which energizes the sealing land (15a). In alternative embodiments the land (15a) contacts a conical secondary sealing surface (16). In yet other embodiments the seal ring contacts a primary sealing surface (12) of the wellhead (11), with or without sealing.

Abstract: A pair of chucks (9, Fig 1) and 15 are actuated via plates (7), 8 by air cylinders (5), 6 to move nose portions (11), 14 into recesses in the ends of a shaft to be supported. Tapers (12), 20 on the nose portions (11), 14 allow for a certain degree of tolerance and centring of the shaft. When the chucks (9), 15 are in place the shaft is carried on the parallel portions (13), 21 of nose portions (11), 14 and linked to a drive component 17 by a key 19 engaging a complementary formation on the shaft. The lifting mechanism for the shaft can then be lowered. A spring 16 allows for any tolerance and ensures that the key 19 is securely located within recesses in the end of the shaft. In use the shaft is expanded into contact with a reel of, for example, paper on the shaft by air supplied to the interior of the shaft through a passageway (22) of the chuck (9).
