Title: Plate clamping apparatus of printing machine
Inventor: UEHARA KAZUMI
IPC: B41L13/10
Filed: 1995-11-28
Abstract: An operating system (5) for clamping a printing plate (S) to a substrate (2), eg a flexible belt, includes fore and rear clamping mechanisms (8, 12) for respectively gripping the leading and trailing edges of the plate. The system also includes a pivotal arm (35) having a roller (4) at its free end for engaging with the clamping mechanisms. The roller serves to pivot a lever (7, fig 2) of the mechanism (8) to the dashed position, and hence allows the leading edge of the plate to be fed beneath the lever. A spring (9) subsequently pivots the lever to grip the plate adjacent a projection (16) on the belt. The rear mechanism (12) is operated in a similar manner. More than one of each of the clamping mechanisms can be arranged across the width of the plate. <IMAGE>

Title: Surveying a well borehole by means of a rate gyro using an error nulling system
Inventor: UTTECHT GARY W
IPC: E21B47/022
Filed: 1995-12-19
Abstract: A positional survey of a well borehole 12 which is subject to deviation from the vertical is made by means of a survey tool 10 having a housing in the form of a sonde 16 containing a rate gyro 24, having an axis of rotation coincident with the longitudinal axis of the sonde, and means 30 for measuring the direction of gravity relative to the sonde, i.e. the angle of inclination of the sonde. The method comprises moving the sonde in the borehole e.g. by means of a slickline 20, taking measurements at spaced locations, and combining the measurements to determine the borehole azimuth and inclination at the spaced locations. The sonde determines a reference North direction at each location by means of a number of measurements made with the rate gyro housing at each of two opposite azimuthal positions relative to its axis of rotation, the housing being rotatable by means of a drive 26. Each set of measurements is averaged, and the standard deviation determined as an indication of the quality of the measurements. The two averages should sum to zero; any residual value is a measure of error, e.g. as a result of drift, and can be used to provide the necessary compensation. <IMAGE>

Patent GB-2312349-A (GB)
Title: Animated parallax display
Inventor: BURDER DAVID GIFFORD
IPC: G02B30/30
Filed: 1996-04-15
Abstract: A lenticular display system has a printed image integral with a viewing screen, capable of displaying continuous animation and, or, three dimensional effects. By a method of directly capturing and interlacing selected frames from a sequence of images from an electronic display monitor, any number of images, whether originally derived from any source such as film, video or computer, may be incorporated into the display. This is to give the effect of continuous two dimensional animation as though viewing a clip from a motion based sequence, or else to give a stereoscopic effect as though viewing a truly dimensional model, or a combination of both effects. Use of this technique as a proofing system allows the opportunity of testing a wide number of alternative sequences before selecting the final sequences for production purposes. By optionally using emulsion coated lenticular lens sheet, raster or coated holographic optical element, or direct digital output to a prelenticulated film, obviates the need for post lamination of emulsion to viewing screen. An automatically activated sound chip may be incorporated into the display so as to simulate the sounds relative to that piece of animation.

Title: Coating thickness gauge
Inventor: MAY PHILIP ANTHONY
IPC: G01B7/06
Filed: 1996-10-07
Abstract: A dual function coating thickness measuring probe comprises a first winding assembly for a ferrous probe function comprising an induction winding 6 and two search or pick-up windings 5 and 7. A second winding assembly for a non-ferrous eddy current based probe function comprises a search winding 2 disposed on a non-magnetic and non-conductive former 9. A magnetic cylindrical core 1 of a material with a high resistance to impact and abrasive wear passes through the windings. A conductive non-magnetic coaxial screen 3 through which the core extends separates induction windings 5, 6 and 7 from eddy current winding 2. The position of the screen is such that it has a minimal effect on the eddy current winding whilst shielding its field from the electromagnetic induction windings. The windings are connected to signal conditioning circuitry which produces outputs representing the coating thickness measured. The probe automatically switches between the induction windings and eddy current winding in response to the nature of the article under test.
Patent GB-2302114-A (GB)
Title: Downhole production well control system and method
Inventor: TUBEL PAULO S
IPC: E21B47/12
Filed: 1996-02-09
Abstract: A downhole production well control system is provided for automatically controlling downhole tools in response to sensed selected downhole parameters. An important feature of this invention is that the automatic control is initiated downhole without an initial control signal from the surface or from some other external source. This control system generally comprises downhole sensors, downhole electromechanical devices and downhole computerized control electronics whereby the control electronics automatically control the electromechanical devices based on input from the downhole sensors. Thus, using the downhole sensors, the downhole computerized control system will monitor actual downhole parameters (such as pressure, temperature, flow, gas influx, etc.) and automatically execute control instructions when the monitored downhole parameters are outside a selected operating range (e.g., indicating an unsafe condition). The automatic control instructions will then cause an electromechanical control device (such as a valve) to actuate a suitable tool (for example, actuate a sliding sleeve or packer; or close a pump or other fluid flow device). The downhole control system of this invention also includes transceivers for two-way communication with the surface as well as a telemetry device for communicating from the surface of the production well to a remote location.

Patent GB-2309607-A (GB)
Title: Light source whose wavelength varies with temperature in order to suppress stimulated Brillouin scattering
Inventor: HAYASHI AKIHIKO
IPC: H04B10/293
Filed: 1996-10-22
Abstract: A laser diode 68 emits signal light, the wavelength of which varies with the temperature of the diode 68. The signal light is modulated with a data signal (main signal) by a modulation unit 82 and is emitted into an optical fibre where Stimulated Brillouin Scattering (SBS) may occur. To suppress SBS a control unit 86 controls the temperature of the laser diode, varying the wavelength of the signal light in synchronization with a low frequency signal from a source 84. This expands the spectral line width of the signal light to at least 100 MHz, such that SBS in the optical fibre is suppressed. A first injection current 70 controls the wavelength of emitted signal light and a second injection current 74 controls the power of the emitted signal light, such that the wavelength can be varied while power remains constant.

Title: Flagpole and method of production thereof
Inventor: BIGGS MATTHEW DAVID
IPC: G09F17/00
Filed: 1997-09-22
Abstract: A flagpole 20 for a portable hand carried flag is described. The flagpole consists of a tube 22 formed by helically winding a strip of semi-rigid paper which is then coated with a thin layer of waterproofing material. An object of the invention is to provide a flagpole which has less utility as a bludgeon or stabbing weapon. This is achieved by ensuring that the flagpole will buckle or break when a transverse load of greater than a predetermined magnitude is applied to the pole. The flagpole is provided with a strengthening insert 26 for strengthening the portion 32 of the flagpole at which the flagpole is held and waved such that the flagpole will buckle at a point outside the strengthened portion 32 when an impact load of sufficient magnitude is applied. The flagpole 20 when so buckled or broken provides a soft and flexible end, at the breakage point, consisting of layers of paper which are not sufficiently rigid to break the skin of a normal football supporter.
