Patent GB-2328497-A (GB)
Title: Missile
Inventor: ZACHARIAS ATHANASSIOS
IPC: F42B/
Filed: 1993-03-19
Abstract: Method for guiding a long missile having a launching engine, a cruise engine, guidance electronics, an active charge and a seeker head down on to a target, for instance a helicopter, in which, after a ballistic flight, the speed of the missile is reduced by means of a braking parachute and the missile is re-orientated into a position substantially perpendicular to the Earth's surface in such a way that the seeker head of the missile is oriented downwards, whereupon, after the seeker head has locked on to the target, the braking parachute is separated and the missile is guided towards the target by the cruise engine, characterised in that, directly before, at or directly after the moment of deployment of the braking parachute, a lateral thruster arranged at the centre of gravity of the missile is activated in such a way that firstly, for accelerating the tilting of the missile into the vertical plane, there is produced a force which is added in a vectorial manner to the force of gravity and which then, during the seeking phase following the tilting over, opposes rolling, pitching and yawing movements of the missile, and the missile is thus stabilized.

Title: Oligosaccharides having growth factor binding affinity
Inventor: GALLAGHER JOHN THOMAS
IPC: C07H3/06
Filed: 1993-03-23
Abstract: Oligosaccharides having a high specific binding affinity for FGF growth factors and made up of less than ten disaccharide units in all are disclosed which include sulphated disaccharide units composed of an N-sulphated glucosamine residue and a 2-0-sulphated iduronic acid residue. A method is also disclosed for preparing these oligosaccharides in a purified and relatively homogeneous state from glycosaminoglycans such as heparan sulphate. For the best FGF-binding affinity there are preferably at least four of the sulphated disaccharide units arranged as an internal contiguous sequence. The most favoured structures contain fourteen monosaccharide residues in all, but structures having twelve monosaccharide residues can also have quite high FGF-binding affinity, at least for bFGF. These oligosaccharides can either activate and stimulate FGF activity or inhibit FGF activity, and uses thereof as drugs for therapeutic purposes in medicine are also disclosed.

Title: File drawer interlock mechanism.
Inventor: MCGREGOR DICKSON J
IPC: E05B65/464
Filed: 1993-09-23
Abstract: An interlock mechanism for a multi-drawer file cabinet assembly, for preventing more than one drawer from being opened at a time. The interlock mechanism includes a series of control rods 30, 32, 34 mounted for axial movement within a series of blocks 52, 54, 56 located in the interior of the cabinet. The control rods are arranged in an abutting end-to-end relationship, forming joints therebetween. A pivotable lever 40 is mounted to the blocks adjacent each joint, and an actuator member 46 is mounted to each drawer 16. Movement of a drawer to its open position causes engagement of the actuator member 46 with one of the levers 40, to pivot it to a position in which the lever 40 separates adjacent control rods, resulting in upward or downward movement of the control rods and vertical displacement of the joints between adjacent control rods. The remaining levers 40 engage the control rods at a location spaced from a joint between control rods, to prevent the remaining drawers from being opened. Movement of the drawer back to its closed position causes engagement of the actuator member 46 with the pivotable lever 40, to pivot the lever to its inoperative position out of engagement with the control rods. The control rods are returned to their original abutting position under the force of springs. <IMAGE>

Title: Sintered metal filter sheet
Inventor: KOEHLER PAUL CHARLES
IPC: B22F3/11
Filed: 1993-10-08
Abstract: Metal filter sheet is made by suspending metal particulates in a liquid containing a stabilizing and binding agent, filtering the stable suspension to leave a wet cake which is then dried, compressed, and sintered to produce the metal filter sheet. The sheet may be graded by filtering successive suspension of different particle sizes and/or shapes. The sheet exhibits a uniform pore structure in every plane normal to the direction of flow, which is demonstrated by its bubble point ratio being about 1.2 or less. B.P.R. is the ratio between the pressure required to force air through the sheet into an alcohol bath at 645, 835 ccs/min/m<2> and the pressure required to produce the first bubble, after correcting the first figure by subtracting the air resistance of the sheet itself.

Title: Microencapsulated adhesive composition and method of making same
Inventor: CHAO HUNG YA
IPC: C09J7/00
Filed: 1993-11-03
Abstract: A microencapsulated adhesive and a method for producing that microencapsulated adhesive is disclosed. The adhesive is produced from an alkyl acrylate or methacrylate monomer having about 4 to about 12 carbons atoms, or a mixture thereof. The monomer is encapsulated by interfacial polymerization, gelatin/gum arabic coacervation or melamine/formaldehyde encapsulation. The microcapsules may be polyamide or polyurea. The monomer is polymerized in the microcapsules by heating to form an adhesive that is non-tacky, but becomes tacky upon application of external forces, such as shearing. The microencapsulated adhesive composition may be used, among other applications, as an adhesive for stamps or envelopes.

Title: Gloves and hand tapper for communicating with deaf-blind people
Inventor: KLEIN ROBERT HENRY
IPC: G09B21/04
Filed: 1995-06-23
Abstract: Words can be entered into a computer character by character using sign language by a pair of gloves having electrodes disposed on their surfaces. When a sign is made, circuits are established between various combinations of electrodes which uniquely identify the sign being made. Signs are read out using a hand tapper comprising a plate having a hand-shaped recess on its surface. Solenoids having tapper pins are disposed beneath the bottom of the recess and at the sides of the recess to allow the hand to be stimulated on its front and sides, thereby producing the sensation of being signed on by another person. The gloves and tapper can be used in a tactile telephone which allows communication between deaf and blind persons,for data entry and read-out, and for allowing deaf blind access to literature via electronic media, such as computer discs or email.

Abstract: A keyboard (1 Fig. 1) having at least one keycap (3,Fig.2) with a transparent front face is disclosed. The keyboard (1 ,Fig. 1) may be placed in front of a display (5,Fig.3) so that an image displayed on the display (5,Fig.3) may be visible through the keycap (3,Fig.2). The keycap (3,Fig.2) may be slidably held by guide members (4,Fig.3) which may be of an "I" shaped configuration (Fig. 2) or of a "T" shaped configuration (Fig. 3). In another embodiment, a keyboard is provided on a transparent substrate (10,Fig.5) of a display (e.g. a liquid crystal display), transparent blocks (11 ,Fig.5) being bonded to the substrate (10,Fig.5) with keycaps (12,Fig.5) having a transparent front face (20,Fig.4a) being disposed in an opaque body (19,Fig.4a) with opaque flags (18,Fig.4a) thereon, the keycaps (12,Fig 4a) being fitted onto the transparent blocks (11,Fig.5), arrays of light emitting diodes (LED's) (16,Fig.5) being provided along two adjacent edges of the substrate (11 Fig.5) and arrays of photo-diodes (17,Fig.5) being provided along the other two edges of the substrate (11,Fig.5). When a keycap (12,Fig.5) is depressed by a user, the optical paths through the gaps enclosing the keycap (12,Fig.5) are blocked by the opaque flags (18,Fig.4a) (normally above the optical paths between the LED's (16,Fig.5) and the photo-diodes (17,Fig.5) so that the outputs of the corresponding photo-diodes (17,Fig.4a) change. The keycap (12,Fig.5) that has been depressed is therefore identifiable since the gaps which are blocked are known and an image displayed on the display (10,Fig.5) will be changed accordingly.
