Title: A process for preparing y-mercaptocarboxylic acid derivatives.
Inventor: QUITTMANN WILHELM
IPC: C07D333/50
Filed: 1994-09-02
Abstract: gamma -Mercaptocarboxylic acids and their derivatives, in particular esters and amides, are prepared from  gamma -butyrolactones via the corresponding thiolactones. The thiolactones are obtained by reaction of the lactones with thiocarboxylates in polar solvents and converted by ring opening with nucleophilic reagents such as, for example, alkali metal alkoxides into the  gamma -mercaptocarboxylic acid derivatives. These are intermediates, for example for the synthesis of leukotriene antagonists.

Title: Positionally dependent pattern checking in character strings using deterministic finite automata
Inventor: LAW DAVID JOHN
IPC: G06F17/30
Filed: 2006-09-01
Granted: 2010-12-08
Abstract: A deterministic finite state machine organised for the detection of positionally significant matches of characters in a string of characters examines each character in turn to determine a exit transition for a current state of the machine to another state The machine responds to an examination of the string of characters by executing in response to a first character at the commencement of the string a transition from an initial state to another state. The machine has at least one state for every character position, includes a exit transition from each state for each character to another state; and possesses only forward exit transitions each from any of the states whereby the current state of the machine unambiguously represents a count of the number of characters from the commencement of the string. The machine may include at least one match state which indicates that all character matches in the string required by at least one respective rule have been detected. Some but not all the states in the multiplicity of states each have a single exit transition for any value of a respective character in the string. At least some of the states in the multiplicity of states each define an exit transition to a state indicating ‘no match’. The machine may be disposed to cease its examination of the character string on attaining a ‘no match’state.

Title: Facsimile-to-cellular telephone system interface
Inventor: CRISTENSEN FINN
IPC: H04N1/00
Filed: 1990-07-19
Granted: 1994-05-18
Abstract: This invention relates to interfaces between facsimile machines and cellular telephone systems (including both cellular subscriber terminals and the fixed part of the system, such as the mobile switching center and the interworking function). The cellular radio telephone system could for example be GSM. To prevent two different facsimile machine timers (specified in the CCITT T.30 recommendation) from expiring during the communication between two such machines connected to the GSM environment, a timer reset command (e.g. a command repeat signal) is automatically sent by the interface (12 or 15) to the facsimile machine on receipt of the command from the facsimile machine, for causing the machine to repeat its command so as to allow time for receipt of a response from the other machine. Instead of sending this response only if a command is not recognized (as recommended in T.30), it is used as the default response whenever the GSM environment receives a command from a facsimile machine. If necessary this response can be used twice.

Title: Communication system with base station transceiver and radio communication units
Inventor: BENN HOWARD
IPC: H04W88/08
Filed: 1995-12-05
Granted: 2000-03-29
Abstract: Signal processing for multiple Radio Frequency (RF) heads (162-172) of a communication system (160) is located at a central control unit (158), such as a base station transceiver. More particularly, in the case where the RF head requires transmission and reception capabilities (in a TDM pico-cellular environment, for example), the central control unit is arranged to undertake power intensive channel coding and channel decoding for each of the RF heads, while the RF heads principally contain RF circuitry required for communication. As such, power consumption and heat generation arising from signal processing is restricted to the central control unit (158), thereby allowing a reduction in the cost and physical size of the RF heads (162-172).

Title: Digital encoding of sound signals
Inventor: ADOUL JEAN-PIERRE
IPC: G10L19/12
Filed: 1996-03-11
Granted: 1997-08-06
Abstract: A codebook is searched in view of encoding a sound signal. This codebook consists of a set of codevectors each of 40 positions and comprising N non-zero-amplitude pulses assignable to predetermined valid positions. To reduce the search complexity, a depth-first search is used which involves a tree structure with levels ordered from 1 through M. A path-building operation takes place at each level whereby a candidate path from the previous level is extended by choosing a predetermined number of new pulses and selecting valid positions for said new pulses in accordance with a given pulse-order rule and a given selection criterion. A path originated at the first level and extended by the path-building operations of subsequent levels determines the respective positions of the N non-zero-amplitude pulse of a candidate codevector. Use of a signal-based pulse-position likelihood estimate during the first few levels enable initial pulse-screening to start the search on favorable conditions. A selection criterion based on maximizing a ratio is used to assess the progress and to choose the best one among competing candidate codevectors.
