Patent GB-2384406-A (GB)
Title: Three party cryptosystem having pairs of private keys
Inventor: YEUN HYUN KU
IPC: H04L9/30
Filed: 2002-01-21
Abstract: Users (A, B) of a cryptosystem send and receive messages with the help of a trusted third party (TTP) using private keys (X) and public keys (P) which encapsulate said private keys. Each user (A, B) holds a private key (X A1 , X B1 ) and the third party is entrusted with a corresponding private key (X A2 , X B2 ) for each user. The trusted third party responds to a challenge (CHA) from a user by issuing a response (RES) which encapsulates the corresponding private key (X A2 , X B2 ) so that the user can use the response in combination with the private key (X A1 , X B1 ) it already holds to decrypt or sign a message. The response takes the form <EMI ID=1.1 HE=6 WI=9 LX=528 LY=1243 TI=CF> <PC>mod p, where r is a private parameter, p is a public system parameter (<I>eg</I>. a large prime) and H is an exponent function (<I>eg</I>. a one-way, collision-resistance hash function). The message (e) is then decrypted to obtain the original message (m) via m = e <EMI ID=1.2 HE=6 WI=23 LX=383 LY=1544 TI=CF> <PC>mod p. This system removes the need for key escrow or Public Key Infrastructure (PKI) since the trusted third party is required to know only a private key corresponding to the private key of each user, rather than the user's private key itself.

Title: Improved door latch assembly with accelerated bolt motion, deadbolt and replacement face plates
Inventor: WHEATLAND GRAHAM JOHN
IPC: E05B63/00
Filed: 2001-02-08
Abstract: A door latch has an adjustable cam (25) to accommodate two backsets of the bore (24) through a door. The cam (25) is operably attached to a handle (14). Rotation of the handle (24) approximately 45{ fully retracts latch bolt (54) and deadbolt (56) through a slide actuator (100) that pulls a link (112) which pivots a cam lever (104) that retracts the bolt (54). The bolt (54) retracting motion is magnified with respect to the motion of actuator (100) via the link (112) and cam lever (104). The link (112) and cam lever (104) are mounted within cylinder section half (52) of housing (28) so as not to interfere with the deadbolt (56) and its slide (150) and deadbolt locking plate (170) that are mounted in a complementary cylinder half (51).
Patent GB-2375995-A (GB)
Title: Maintenance mist control
Inventor: ALDRICH CHARLES STANLEY
IPC: B41J2/165
Filed: 2001-02-16
Abstract: An ink mist controller for a maintenance station including spit louvers (23) and a spit wheel (25) which serve as accumulating surfaces. A flow of air (59) directs ink mist (55, 57) through the louvers and around the spit wheel. Mist that is attached to a surface is carried to a manifold (33) which filters, then exhausts, air to the environment, thereby preventing contamination of articles surrounding the printer. Color ink droplets are ejected onto the spit louvers. Low pressure is created between and below the louvers, which increases air and mist velocity over the entire spit zone. An unrestricted air curtain occurs on three sides of the color printhead to further control the location of mist deposit. Black ink is ejected onto the spit wheel which holds the mist deposit during evaporation. At defined intervals, the spit wheel rotates a fraction of a revolution. A scraper removes the non-volatile residue from the wheel during rotation. An air curtain is created on all four sides of the spit wheel to direct mist to this surface. As with the color ink, contaminated air is filtered prior to being exhausted to the environment.

Title: Closure mechanism for a beverage preparation machine
Inventor: HALLIDAY ANDREW
IPC: B65D81/00
Filed: 2003-01-24
Abstract: A closure mechanism is disclosed for a domestic beverage preparation machine of the type which can receive various sealed beverage containing cartridges through which an aqueous medium, typically water, is passed under pressure. The mechanism comprises relatively movable lower and upper parts between which a cartridge can be inserted. In the closed position the closure mechanism exerts a compressive force of greater than 130N on the cartridge, preferably 200N. This force ensures that the cartridge is held firmly and that the internal dimensions of passageways and apertures in the cartridge are unable to change during pressurisation of the cartridge.
