Title: Injecting liquids into trees
Inventor: BARRANCO NAVERO DIEGO
IPC: A01G7/06
Filed: 1988-11-30
Abstract: According to the invention, the liquid is introduced into the transpiration current of the xylem, in order to provide a distribution of the product applied in a natural and uniform way. The method consists in making a blind hole in the trunk and next imbedding the apparatus in this hole so that the product contained in the apparatus is distributed through the trunk. The apparatus is made up of two basic elements, one formed by an injector 1 which is inserted into the hole made in the trunk and another formed by an elastic tube 2 which is coupled onto one of the ends of the injector and in which the liquid is placed, this tube providing for injection of the liquid at a pressure less than 2 kg/cm<2>. <IMAGE>

Title: Improvements in or relating to methods and apparatus for the continuous formation of an extruded product
Inventor: ALLEN PETER STEWART
IPC: B29C48/48
Filed: 1990-09-19
Abstract: PCT No. PCT/GB90/00025 Sec. 371 Date Aug. 31, 1990 Sec. 102(e) Date Aug. 31, 1990 PCT Filed Jan. 9, 1990 PCT Pub. No. WO90/08024 PCT Pub. Date Jul. 26, 1990.In a method and apparatus for formation of an extruded product from material containing fibrous, molecules or other constituents succeptable to alignment, while the extrudate is still molten and moving through the die (5), in the direction of the extrusion axis (11), it is subjected to pulsating displacements in a direction transverse relative to that axis. These displacements give rise to a shearing action within the material, resulting in a degree of transverse orientation of the constituents. This orientation may be "locked in" to the extruded product when the melt solidifies (40), so improving the transverse strength of that product, and/or may correct an unwanted orientation (from 112, FIG. 16) that existed in the melt upstream of the point where the pulsating displacements were applied. The displacements may be applied by the synchronized operation of pistons (20-27), operating in chambers (17) which open into the die cavity (18) at separated locations all lying in the same transverse plane. The extrusion of products of rectangular, tubular and other sections is described, as are various methods (8a, 8b, 9, 10, 37) of applying forced cooling to the die to accelerate the solidification of the molten product.

Title: Edge soldering of electronic components
Inventor: STUBBINGS ANDREW NEIL
IPC: H05K3/40
Filed: 1990-09-27
Abstract: A printed circuit board (10) has channels (17) formed across the edges of the board. The channels are electroplated with metal to be in electrical connection with tracks (11, 12) on the board. A liquid crystal display of the same size as the board is mounted on the board and has wire leads extending vertically from the display. The leads lie in the channels and are soldered to the channels. The channels may be formed by drilling holes through an oversized board, plating the inside surfaces of the holes with metal, and cutting through the board along a line which passes across the holes to trim off the edge of the board. <IMAGE>

Title: Electromagnetic levitation type continuous metal casting apparatus
Inventor: YAMADA MASAHIKO
IPC: B22D11/14
Filed: 1990-11-30
Abstract: A molten metal storing furnace (2) is connected by a supply tube structure (7) to a casting vessel (3) for upwardly receiving and holding molten metal in the form of a molten metal column and cooling means (4) is disposed on the outer periphery of the casting vessel (3) for cooling and solidifying the molten metal column. The molten metal column is upwardly moved by the effect of an alternating electromagnetic field provided by generation means (5) in the form of coils disposed on the outer periphery of the casting vessel (3). High frequency heating means (8) is disposed on the outer periphery of the molten metal supply tube structure (7) and the latter has at a bend section (7a) leading to the casting vessel an appendix section (7b) with associated high-frequency heating means (8a). The levitation-producing coils (5a1, 5a2, Fig. 5) surround the casting vessel (3) to a lower level than the cooling means (4) and the latter provides a reverse-flow channel having a downward coolant flow direction nearest the casting vessel wall (3a) and a return flow channel nearest the generating means (5). The channels meet, (4a), in the zone of the coil (5a2) above the lowermost coil. In another embodiment, (Figs. 6, 7 not shown), the horizontal tube of the supply tube structure is connected with the vessel (2) at a level higher than the normal molten metal level when the melt displacer (9) is in its withdrawn state. <IMAGE>

The computer system also includes an additional pulse-forming unit (56) which, for one of the computing units, produces (by means of 62, 72) an independent reset pulse in order to ensure orderly putting into operation of the computer system. <IMAGE>
Patent GB-2254744-A (GB)
Title: Vestigial sideband modulator
Inventor: RIXON ALAN ROBERT
IPC: H04N5/40
Filed: 1991-04-11
Abstract: In a vestigial sideband (vsb) modulator, an i.f. signal 8 is modulated 7 with a baseband input usually a video input and the extreme part of one of the sidebands is removed with a vestigial sideband filter 9 to provide the right frequency response shape for a transmission. The filtered video-modulated i.f. signal is demodulated 10, 11 to quadrature baseband components using the i.f. signal oscillator 8, and quadrature components at carrier frequency from a carrier oscillator 17 are modulated with these baseband components to produce on combination 19 a vsb modulated video output at carrier frequency. A channel filter as used in the prior an is not required. The phase of the i.f. signal used to demodulate to quadrature baseband may be shifted 26 to maintain a baseband component in quadrature with an i.f. component of the modulated i.f. signal. The vsb modulator may be used in television transmitters or video test equipment. <IMAGE>

IPC: H04N1/113
Filed: 1992-06-25
Abstract: The system includes a gas laser 10 emitting a write beam, a polygonal mirror 20 deflecting and scanning light from the gas laser 10, a lens 40 that is telecentric with respect to an image plane 30 and which focuses the deflected light on to the image plane 30, a focus detector 50 that receives light reflected from the image plane 30 to detect the state of focusing on the plane by the lens 40, and a focus adjusting unit 60 that focusses lens 40. This optical system can be correctly focussed despite any waviness, tilting etc. of the image plane 30 even if the F number of the system is reduced. Focus detector 50 may use light from the write beam (fig 2) or from a dedicated source 51. It may use the same techniques as those commonly used for focussing CD players.

Title: Communications security and trusted path method and means
Inventor: ANDERSON MARK STEPHEN
IPC: G06F21/84
Filed: 1992-10-30
Abstract: A trusted path device is described which may be used stand alone or may be retrofitted to a users untrusted computer console or workstation so that an untrusted data input may be displayed on an untrusted display and verified by the user, following which the trusted data can be output to an untrusted or trusted device or network. The output may be encrypted or not, by means of an encryption device which may or may not use a 'one time pad' key provided from a structured array of retrievable "one time pad" keys having associated uniquely there with, a serial number which itself need not be encrypted but with which the input data and encrypted output data are uniquely associated. Sufficient "one time pad" keys are provided on a commonly available and physically manageable medium so as to allow much simplified key management procedures while still maintaining high levels of correctness and effectiveness of the encryption processes. Trusted devices as per ITSEC Level 6 may be used to implement the trusted path and encryption devices since the apparatus according to the invention are inherently simple in functionality thereby simplifying conformance with the relevant ITSEC and security equivalent requirements. Access to trusted components of the system e.g. memory 33, processor 32, encryption/decryption 37,38, is only allowed on receipt of a request at untrusted input interface 40. A trusted user has the request and/or data displayed on VDU 36 and manually activates a verifier to allow access. Thus external untrusted networks etc. only have access to equally untrusted internal components.
