Title: A bale-sheathing device
Inventor: STIRLING WILLIAM
IPC: A01F15/07
Filed: 1990-01-17
Abstract: A bale sheathing device for loading bales (12) of an agricultural product, e.g. silage, into an elongated, flexible bag 10, comprises a framework (22) movable along the ground and supporting an open-ended drum 11 that has an outer surface for supporting the bag in a compressed condition. The device has pads 36 connected to the framework that can be lowered to a location underlying the wheels 40 of a vehicle that is used to load a bale through the drum and into a space in the bag beyond the drum. The result is to immobilize the device during the loading operation by virtue of the weight of the vehicle on the pads. The same vehicle can be used between bale loading operations to pull the sheathing device forwards to a new location to dispense a portion of the bag from the surface of the drum and hence create a space in the bag to receive the next bale. …<IMAGE>…

Title: Electroforming mandrel; making continuously electroformed thickness modulated or perforated metal foil
Inventor: DAVIES DAFYDD GERAINT
IPC: C25D1/08
Filed: 1990-05-04
Abstract: An electroforming mandrel for making metal foil with holes therein comprises areas capable of behaving as an efficient cathode together with a predetermined pattern of more resistive or dielectric areas where plating efficiency is impaired or is zero. The mandrel can be prepared by local chemical conversion of the surface of the mandrel e.g. by ion implantation, ion assisted plasma vapour deposition or anodisation to form the resistive areas. Metal foil is also formed by printing an electroformed foil with a pattern of plating resist and thereafter plating the foil to give a compound foil thickness modulated or having apertures or lacunae or cavities. Applications mentioned are the manufacture of printing screens, and security labels.

Title: Image data encoding and compression
Inventor: CHAN KENNETH L
IPC: G06T9/20
Filed: 1990-12-31
Abstract: An image processing system comprises a source (2) of digital electronic image data to be processed. The image data is processed by a processor on a line by line basis by detecting (4) edges in the image such as for example discontinuities in intensity and by representing the intensity profile between detected edges as a mathematical expression such as a polynomial function to reduce the amount of data used to define the image. Data representing the detected edges and data relating to the mathematical expressions are stored as a data set for further processing. The data set for one image may be compared to that for another similar image in order to match features between images and thereby produce three dimensional information about a scene. <IMAGE>

Title: Ionospheric sounding equipment
Inventor: ARTHUR PAUL CHRISTOPHER
IPC: G01S13/02
Filed: 1991-01-08
Abstract: Ionospheric sounding equipment receives and measures the intensity of a chirp signal generated at a remote location, generates a similar, replica chirp signal, mixes said chirp signals to generate a difference frequency signal indicative of the propagation time of the remotely-generated chirp signal, spectrally analyses the difference frequency signal over a succession of timed intervals, and plots as an ionogram the frequency of said difference frequency signal against the frequency of the replica chirp signal; the variation in intensity with frequency of said frequency difference signal being indicated. The intensity of said frequency difference signal is conveniently indicated by coloration, in which specific colours correspond to specific signal strengths. The ionogram may usefully provide a key to indicate to users the correspondence between colour and signal strength. As described, the chirp signal is swept from 2 to 30 MHz in 280 seconds and each spectral analysis is made on a chirp sweep of 1.36 seconds, the analyses being repeated 3 times per second at a resolution of 0.73Hz over a range of 500Hz.

Abstract: A suction regulator (18) for a pleural drainage device (1) which includes a spring-loaded valve (22) which opens to atmosphere to maintain the appropriate suction levels in the pleural drainage device (1) comprises an air flow regulator (23) which reduces the air flow to the drainage device (1) when the suction level from the suction source exceeds a predetermined level. A tapered passageway (24) is provided in the air flow path from the suction source to the pleural drainage device (1) and a ball valve (26) is slidably disposed within the tapered passageway (24) so that when the air flow through the passageway (24) increases, the ball valve (26) rises to decrease the amount of air passing through the passageway (24). A guide rod may pass through a central bore in the valve (26). <IMAGE>
Patent GB-2241607-A (GB)
Title: Method of planarizing a dielectric formed over a semiconductor substrate
Inventor: MORIMOTO SEIICHI
IPC: B24B37/10
Filed: 1991-01-17
Abstract: The substrate 22 is pressed face down against a table 20 which has been coated with an abrasive material. In this way, the upper surface of the interlayer dielectric contacts the abrasive. Rotational movement of the water relative to the table facilitates removal of the protruding portions of the interlayer dielectric by the abrasive. Post-planarization step height variation is minimized by simultaneously cooling the table and the abrasive material during the abrasive or polishing process. By maintaining the table and the abrasive at about 10 degrees Celsius the step height variation is reduced by a factor of 2 over that normally realized in the prior art. <IMAGE>

Title: Rotation-resisting bolt
Inventor: GARDNER IAN
IPC: F16B33/00
Filed: 1995-04-26
Abstract: A bolt has a shank (3) with a non-threaded length (5) of generally elliptical cross-section which will cooperate with the aperture or apertures into which it is inserted, in order to prevent or minimise rotation of the bolt.
