Title: Protective cover for car roof
Inventor: LIN YU
IPC: B60J11/00
Filed: 1989-08-26
Abstract: A protective cover for a car roof which is easy to mount on the car roof or detach from the roof to serve as a baggage rack includes a pair of expansion rods (2, 2 min ) respectively mounted on the roof of a car at each side of the vehicle The expansion rods each have a stepped pawl coupling means (27) mounted thereon at each end to support two reels (1, 1 min ). The two reels (1, 1 min ) have a cover sheet (6) therebetween and are spaced from each other, being mounted on the expansion rods (2, 2') at both ends so as longitudinally to stretch the cover sheet. A cross link (3) is set transversely in the middle to push the expansion rods (2, 2') outwards so as to stretch the cover shoot transversely. Through the stretching force applied to the cover sheet longitudinally and transversely, the cover shoot becomes firmly positioned spaced from the roof of the car to protect it against strong wind and to provide good ventilation. By locking means set in one of the pawl coupling means (27), the whole rack assembly is fixedly locked to the car roof to protect it against burglary. <IMAGE>

Title: Cylinder wall surface treatment
Inventor: MIDDLETON IAN COROON
IPC: F16J10/04
Filed: 1989-12-29
Abstract: The surface finish of the internal cylinder wall of an internal combustion engine is produced by honing the surface and then after honing applying a sealing composition 14 to the surface to at least partially fill the valleys 12 left in the surface by the honing operation. After the sealing composition has set, pistons with piston rings are assembled in the cylinders and the engine is then run. Peaks 16 will then be removed by the rubbing action of the piston rings. By coating the surface in this way, oil consumption is reduced, which in turn leads to a reduction in engine emissions. <IMAGE>

IPC: H01P1/165
Filed: 1990-02-05
Abstract: A polarisation controller for a radio frequency transmitter comprises a first polarisation rotator (4) having an input for coupling to the source 1, a polarisation resolver (8) coupled to an output of the first polarisation rotator (4) to resolve the output of the first rotator into components of two mutually perpendicular polarisations, a phase shifter (10) having an input coupled to one output of the polarisation resolver (8), a polarisation combiner (12) having inputs for waves of two mutually perpendicular polarisations one of which is coupled to an output of the phase shifter (10) and the other of which is coupled to the other output of the polarisation resolver (8), and a second polarisation rotator (15) having an input connected to the output of the polarisation combiner (12) and an output for coupling to an antenna (17). In radio frequency transmitters there is a need to transmit radio frequency waves of predetermined polarisation. It is also desirable to be able to vary the transmitted polarisation state rapidly at will or in response to a feedback signal to, for example, improve subsequent reception of the transmitted signal. <IMAGE>

Title: Stabilising documents during processing by office machinery.
Inventor: PARE ELAINE MARGARET
IPC: B41J11/55
Filed: 1991-05-17
Abstract: A device for stabilising documents, for example in a typewriter, comprises a sheet (10) of a flexible material having an adhesive strip (12) along one edge thereof. The adhesive strips may be protected by a release-paper. Devices (10) may, for example, be made as discrete items, or as a continuous roll from which the items may be detached. In use, the device is adhered to the bottom edge of the front face a document with the adhesive stripe slightly overlapped therewith. As the document is transported by the platen of an office machine, the device adheres to the platen at approximately the same time as the pressure rollers of the machine lose contact with the lower edge, thereby preventing the paper from skewing when printing close to said lower edge. <IMAGE>

Patent GB-2253760-A (GB)
Title: Video image processing
Inventor: WESTON MARTIN
IPC: H04N7/46
Filed: 1992-01-31
Abstract: Motion vectors are determined for a video image by reference to the following image only. Vectors so determined are used to control a multi-tap motion-compensated temporal interpolation filter in order to interpolate one or more images between the image and the following image. The temporal interpolation filter uses primarily or wholly samples from the following images, since this approach gives valid answers in areas of both foreground and revealed background; whereas the motion estimation algorithm cannot distinguish between such regions. The same principle may be applied when motion vectors are derived by reference to preceding images only, that is, the filter takes contributions predominantly or wholly from preceding images. <IMAGE>

Title: Measuring the time for forming a refractive index grating of a photo-nonlinear medium
Inventor: UESU YOSHIAKI
IPC: H01S3/108
Filed: 1992-09-25
Abstract: A method of measuring the time for forming a refractive index grating 6 of a photo-nonlinear medium wherein a laser beam with a wavelength lambda  emitted from a laser beam source is split into first and second pump beams 2, 3, which are incident on surfaces 1a, b of a photo-nonlinear medium 1 from opposing directions on the same optical path, and a probe beam 4 which is incident on the surface 1a forming an angle with the first pump beam 2 to generate interference fringes in the normal direction of the surface and to form a refractive index grating 6. A phase conjugate wave 5 is emitted in the reverse direction to the probe beam 4 by means of irradiating the second pump beam 2 on the refractive index grating. A direct-current electric field is applied on a pair of external electrodes 1c, d where by providing a frequency modulation to the first pump beam 2 using a piezoelectric oscillator 7, a moving speed of the interference fringes is determined when light intensity of the phase conjugate wave 5 is maximized. An accurate and rapid measurement of the forming time of the refractive index grating of the photononlinear medium can thus be obtained. <IMAGE>

Title: A parquet panel
Inventor: CANCIO GUILLERMO IBARGOYEN
IPC: E04F15/02
Filed: 1993-02-10
Abstract: A parquet panel has a base body, a wooden sheet secured to the base body and a melamine-based layer polymerised directly onto the wooden sheet to form a wear-resistant operating surface. The melamine-based layer is applied by dipping or immersing the wooden sheet in a melamine bath until it is completely soaked before being allowed to dry whereby the melamine polymerizes not only on the surface of the sheet but also within the pores of the wood. The sheet is pressed before being joined to the base body. The resulting panel is extremely hard-wearing and its appearance can be restored simply by polishing. <IMAGE>

Title: Optical detection of liquid dew-point of a gas stream.
Inventor: HIRST WILLIAM JOSEPH SENIOR
IPC: G01N25/70
Filed: 1993-06-21
Abstract: The liquid dew-point of a gas stream 1 is measured directly. Regular measurements of the dew-point are performed by measuring the optical transmission of an amount of gas tapped from a gas-transport line 9. The ratio of the intensities at two different wavelengths is measured as a function of temperature. The temperature is changed until this ratio abruptly changes, which gives an indication of dew-point. Two narrow-band filters centred on 1.89  mu m and 1.98  mu m we disposed in front of respective modulated sources 3 (or detectors). The temperature of the sample tube 1 is ramped between +3 DEG C to -20 DEG C by a jacket 2. The invention is applicable to measuring the water dew-point of natural gas. <IMAGE>

Title: Peak detector circuitry for use in nuclear logging apparatus
Inventor: NORDSTROM ROY
IPC: E21B47/01
Filed: 1993-12-03
Abstract: In the nuclear logging apparatus radiation detectors output signals via a multiplexer (176, Fig 24, not shown) to a programmable gain amplifier (178) which improves signal to noise ratio and quantifies pulse amplitudes within predetermined spectral limits. The output signal from the PGA is received by peak detection means 180 which converts the signal to a stable DC pulse for digitising by an A/D converter (184). The peak detection circuit includes a first unitary gain follower U9 through which a memory capacitor C57 is charged to the same voltage as the input pulses, a second unitary gain follower U12 to isolate the capacitor from the output, and a digital comparator U10 which opens a switch SW1 when the input pulse reaches its peak to isolate the memory capacitor. <IMAGE>
