Title: Authentication method and apparatus using one time pads
Inventor: HARRISON KEITH ALEXANDER
IPC: H04L9/08
Filed: 2009-02-24
Abstract: An authentication method is provided between entities having matching one-time pads each with multiple OTP blocks. From the standpoint of a first one of the entities, the method involves sending a challenge that it has generated by subjecting a first OTP block to a randomly-selected member of a first family of hashing functions. Each member of the first hashing-function family is associated with a respective member of a second family of hashing functions. On receiving back a response, the first entity tests whether the response originates from the second entity by seeking a match between the response and a reference value generated by subjecting a predetermined said OTP block to the member of the second hashing-function family that is associated with the member of the first hashing-function family used to generate the challenge.

Patent GB-2470069-A (GB)
Title: Quantum Repeater and System and Method for Creating Extended Entanglements
Inventor: MUNRO WILLIAM
IPC: H04B10/70
Filed: 2009-05-08
Abstract: A quantum repeater (20) performs quantum entanglements (25,26) with left and right neighbour nodes (21,22) to produce entangled photon pairs (qb1 and qb3 ; qb2 and qb4). Entanglement swapping is then carried out in a merge operation, at the repeater using photons (gb3,gb4) from each pair, so that photons qb 1 and qb2 become entangled. This procedure may be carried out iteratively using a chain of repeaters to transfer entanglements large distances (e.g. fig.9, not shown). Prior to a merge operation, a repeater waits to receive notification from its preceding neighbour indicating that the neighbour has successfully merged its pairs, and the repeater also ensures that an entangled pair exists between it and the succeeding neighbour. To establish entangled pairs, plural photons may be sent from the preceding neighbour to enhance the chances of successful pair creation.(e.g. fig.22, not shown). Multiple entangled pairs may be created between neighbours and kept as spares (e.g. fig. 18, not shown). Applications include quantum key distribution (QKD) and quantum computing.

Title: A combustion engine for conveying a hydraulic pressure medium
Inventor: EICKMANN KARL
IPC: F02B63/06
Filed: 1962-02-02
Abstract: 1,020,829. Reciprocating pumps; two stroke I.C. engines. R. BREINLICH. Feb. 2, 1962, No. 10334/65. Divided out of 998,875. Headings F1A and F1B. The coupling between a free-piston I.C. engine and a pump is such that the varying force produced by the-engine piston 2 is transformed into a substantially uniform force acting on the pump piston or pistons 10. In Fig. 4, a cam 48 on engine piston rod 5 actuates pump pistons 10. The effective pump stroke is varied by an adjustable stop 68 in a fixed cylinder 67 slidably receiving pump cylinder 9. The compression stroke of engine piston 2 is effected by applying liquid pressure to piston rod extension 15 in chamber 16. Uniform wear is achieved by rotating the engine piston assembly by pins 119 engaging helical grooves 120 in the piston rod, or by a rotary motor. In another embodiment, a plurality of cams are mounted on piston rod 5 and, as well as actuating the pump pistons, serve to actuate piston and cylinder assemblies hydraulically controlling the engine inlet and exhaust valves, injection and ignition, and may control the corresponding auxiliaries of another engine, when a plurality of engines are used. In another embodiment, (Fig. 3, not shown), pump pistons 10 are pivoted to piston rod 5 and the pump cylinders are pivotally mounted. The load on pivot bearings 65 is hydraulically balanced by the pump pressure acting through passage 107 and chamber 106, the piston pivots 63 and the roller bearings. Fig. 4, may be similarly balanced. In another embodiment, the extension of the engine piston rod acts as a slide valve means to control the engine auxiliaries or those of another engine. The chamber beneath engine piston 2 may be employed for pre-compressing the engine fuel-air mixture, or as a pump, a compressor or as a second combustion chamber.

Title: Process of preparing an agent for inactivating proteolytic enzymes
IPC: A61K38/57
Filed: 1949-04-20
Abstract: A medicinal agent for inactivating proteoyltic enzymes in the treatment of peptic ulcer is prepared by combining an acid-adsorbing resin with a mono-alkyl sulphuric ester having an alkyl chain of from 6 to 30 carbon atoms.  The preferred resin is a polyamine phenol formaldehyde acid adsorbing resin (e.g. the polyethylene polyamine methylene substituted resin of diphenylol dimethyl methane and formaldehyde) in base form.  Other suitable resins are metaphenylene diamine-formaldehyde; resins prepared from amines and polysaccharides, ethanolamine alkyl resins, alkylated aromatic diamines, aromatic amines both unmodified and modified by incorporating into the resin structure during preparation alkyl groups to form quaternary ammonium bases; amine resins co-condensed with aliphatic polyamines or polyimines; amine resins treated during preparation with cyanamide or dicyandiamide; and resins prepared by reacting aliphatic polyamines with polyhalogen derivatives of hydrocarbons.  Suitable sulphuric acid esters include the dodecyl and tetradecyl mono esters of sulphuric acid.  The agent may be prepared by contacting an aqueous solution of the sodium salt of the sulphuric acid ester with a cation exchange resin (e.g. phenol-formaldehyde) and bringing the clear filtrate which now contains the mono sulphuric acid ester into contact with the acid adsorbing resin. Alternatively and preferably the aqueous solution of the alkyl sulphate is passed through a mixture of the cation exchange resin and the acid adsorbing resin, the particle size of one resin being substantially different from the particle size of the other, and the two resins being subsequently separated by screening, sedimentation or centrifuging. Preferably the particles of the acid adsorbing resin are the smaller. The agents are administered, if desired, in admixture with flavouring and colouring materials, clay, bentonite, magnesium or aluminium oxide, aluminium phosphates, basic aluminium acetates, bismuth suboxide, bismuth or zirconium subcarbonates methyl cellulose, carboxy methyl cellulose, gastric muscin, sulphated gluten, gums, muculages, gelatin, amino acids and other salts, peptones and peptides.
