Patent GB-2226455-A (GB)
Title: Electromagnetic actuator
Inventor: POTTER JAMES CHARLES
IPC: H01F7/16
Filed: 1988-12-20
Abstract: The electromagnetic actuator for a fuel control valve in an internal combustion engine comprises a core member 28 which extends through the opposite walls 12, 13 of an open ended housing. The open end of the housing is closed by a cover 16 and surrounding the core member within the housing is a winding 29. Seals are provided between the core member and the wall of the housing and pole pieces 27 are connected to the opposite ends of the core member exterior of the housing. When the winding is de-energised, fuel pressure in a passage 18 lifts ball valve 23 as well as a cap 22 and armature 25 to supply fuel to a passage 20. The housing isolates winding 29 from the fuel. <IMAGE>

Title: "Holographic data carriers"
Inventor: DRINKWATER KENNETH JOHN
IPC: G03H1/20
Filed: 1989-06-08
Abstract: A process for the manufacture of coded arrays of holographic optical elements (HOEs) for use on data carriers to represent e.g. identification data on access-control cards or authentication data for documents or goods. The process accordingly involves the creation of a master hologram (4) which is constructed to diffract incident light (5) into a plurality of different reconstructed beams (6) and the use of the master hologram in a holographic production system to direct its reconstructed beams (6) into a recording medium (2) for interference with a reference beam, the reference (3) and/or said reconstructed (6) beams being spatially modulated by a mask (7) comprising a coded array of discrete transparent areas. In this way a large number of different coded HOE arrays with multiple reconstructed beams can be produced from only one (or a limited number of) master hologram(s) in conjunction with differently coded masks. <IMAGE>

Title: A sizing composition.
Inventor: BLIXT TONY
IPC: D21H23/26
Filed: 1989-06-22
Abstract: The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.05 to 0.40. Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion , which is subsequently subjected to shear forces to reduce the particle size of the emulsion. The invention also relates to a method of preparing sized paper or paperboard by using the above-mentioned sizing composition. Also, the invention relates to the sized paper for paperboard prepared by said method. Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced consumption of optical highteners, and enhanced development of sizing.

Title: Neural network employing absolute value calculating synapse
Inventor: CASTRO HERNAN A
IPC: G06N3/063
Filed: 1993-03-19
Abstract: A neural network employs absolute difference calculating synapse cells each with a pair of floating gate devices 21, 22 coupled in parallel between an internal cell node 24 and a column line 27 of the network.
