Title: Determination of dimensions of mail items
Inventor: GILHAM DENNIS THOMAS
IPC: G07B17/00
Filed: 1990-09-10
Abstract: Apparatus for determining the thickness dimension of a mail item 40 works by feeding the item between a feeding surface and a roller 42 which has an outer surface 44 of piezo-resistive material so that its resistance changes in dependence upon the deformation of the surface by passage of the item and thereby provides a signal representing its thickness. In addition means are disclosed to determine other dimensions of the item either by providing the roller with a plurality of piezo-resistive segments so that the number of deformed segments indicates width of the item or by non-contact sensors. The dimension signals together with weight signals may be input to a franking meter to set the postage charge to be franked. The necessary signal processing may be performed within hollow roller shaft 52, Fig. 11, and the result fed out by an infra-red link or slip rings 45. Fig. 11 shows a roller having a plurality of coaxial segments 48 each having a piezo-resistive surface element 47 connected via electrodes 50, 51 which are insulated by spacers 53. <IMAGE>

Title: Estimation of polymer adsorptiveness of oil-reservoir rock
Inventor: JOHNSON PETER ANTHONY VICTOR
IPC: E21B47/10
Filed: 1990-09-26
Abstract: A method of estimating from in situ measurements the adsorptiveness of a rock matrix for organic polymers such as xanthan, which are used in waterflooding for enhanced oil recovery from an oil reservoir, involves injecting water into the rock, and adding a mixture containing two radioactive ions. One ion interacts with the rock (e.g. calcium-45), undergoing ion-exchange, while the other (e.g. chloride-36) interacts negligibly. Measurement of the arrival times for the two ions at a location from which the water is extracted enables the retardation factor R for the interacting ions to be determined. The polymer adsorptiveness X of the rock is found to correlate with this retardation factor R, and with the permeability k of the rock.

Title: Autofocus systems
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: H04N5/232
Filed: 1991-07-25
Abstract: In an autofocus system for a camera provided with an image sensor 16 and a motor-driven 18 focussing lens 12, the image sensor 16 is mounted on a dither transducer 20 which receives dither oscillations TDS from a control circuit 22. The control circuit 22 also provides a motor drive signal MDS to move the focussing lens 12. The image sensor 16 is physically oscillated along the optical axis 10 at a rate less than field rate, but fast enough for the resulting out-of-focus movements not to be perceivable. The control circuit 22 responds to high-frequency information in the image signal ISS to set the focussing lens 12 at a position such that the high-frequency information is maximised within the range B of the physical dither provided by the transducer 20. Once optimum focus has been reached, the TDS signal can be used to check focus continuously whilst leaving the focussing lens 12 stationary. <IMAGE>

Title: Improvements in or relating to steerable rotary drilling systems
Inventor: BARR JOHN DENZIL
IPC: E21B47/01
Filed: 1992-06-23
Abstract: A system for maintaining a downhole instrumentation package in a roll stabilised orientation with respect to a drill string comprises an instrument carrier (812) which is mounted within a drill collar (810) for rotation about the longitudinal axis of the collar. An impeller (815) is mounted on the instrument carrier so as to rotate the carrier relatively to the drill collar as a result of the flow of drilling fluid along the drill collar during drilling. The torque transmitted to the instrument carrier (812) is controlled, in response to signals from sensors in the carrier which respond to the rotational orientation of the carrier, and input signals indicating the required roll angle of the carrier, so as to rotate the carrier (812) in the opposite direction to the drill collar (810) and at the same speed, so as to maintain the carrier non-rotating in space and hence roll stabilised. The torque may be controlled by controlling a variable coupling (851,852) between the impeller and the carrier and/or by controlling a brake (857), for example in the form of a differential gear mechanism, between the carrier and the drill collar. <IMAGE>

Title: Nozzle control system particularly for envelope flap moistener
Inventor: BERGMAN NORMAN J
IPC: B43M5/04
Filed: 1993-12-03
Abstract: In a high speed mailing machine, envelopes 42 are moved past a moistening nozzle 16 along a given path with the opened flap extending from the envelope. A sensor attached to the nozzle senses the location of the edge of the flap as the flap moves past the nozzle, and causes the nozzle to track the flap edge. The nozzle is pre-positioned in response to an envelope sensor 70 located further upstream of the tracking sensor. When the upstream sensor 70 to detects the arrival of an envelope, the nozzle is moved to a start position. The tracking sensor may be mounted so that it moves with the nozzle. A low bandwidth servo loop controls the response to the upstream sensor and a higher bandwidth servo loop controls tracking of the nozzle in response to the tracking sensor. It is not necessary to use stored or computed envelope flap profiles, envelope speeds, etc., for the nozzle to track the envelope flap. <IMAGE>

Filed: 1994-07-07
Abstract: A safety lampholder for a bayonet bulb comprises a housing 10 defining slots 11 to receive the bayonet pins of a bulb. Contacts 57 are provided within the housing 10. Axially moveable and rotatable shutter means 20 are also provided for selectively obstructing access to the contacts 57 and are moveable between a first inoperative position, in which the contacts 57 are shielded by the shutter means 20, and a second operative position in which the contacts 57 extend through apertures in the shutter means 20 for bearing against pad electrodes 101 of a bulb. Axial displacement of the shutter means is inhibited by shutter stops 26 abutting ribs 59 on a terminal block 50. On axial insertion of a bulb into the lampholder, the bulb shoulder 100 pushes shutter driving means 40 inwardly of the housing to rotate the shutter means by cooperating cams 24, 42 or gears and to align shutter apertures with the contacts. This displaces the shutter stops 26 relative to the ribs 59, to allow displacement of the shutter means 20 axially inwardly of the housing to the second operative position. The bulb is subsequently rotated to secure its bayonet pins in slots 11. The shutter means can comprise shutter halves driven to rotate relative to one another to release the stops and align the apertures. <IMAGE>
