Patent GB-2236293-A (GB)
Title: VTOL Aircraft and water craft
Inventor: ADIMORA ANTHONY NGORNADI
IPC: B64C21/04
Filed: 1990-08-20
Abstract: By blowing a blanket of air over an air vehicle's or craft's wings or top surfaces, the static pressure over the wings or top surfaces decreases (Bernouli's theorem). With the pressure over the vehicle's or craft's wings or top surfaces decreased sufficiently the air pressure underneath the vehicle or craft pushes it upwards. Thus vehicles or crafts using the above principle can take off and land vertically. Blowing air over appropriate surfaces of the vehicles or crafts enables the air pressure to propel or push the said vehicles or crafts forward or in any direction. Also applicable to under water craft, blowing water over the upper surfaces. <IMAGE>

Patent GB-2255357-A (GB)
Title: Prestressed steel joist
Inventor: CARNALL MARK
IPC: E04C3/10
Filed: 1992-02-10
Abstract: A steel joist has an upper flange (10) and a vertical webbing (11) hot rolled in a T-section and cambered so that the top flange is concave when viewed from the top. The lower flange (13) has a channel (12) which accommodates the vertical webbing and prevents it from buckling under compression when the lower flange is tensioned.

Patent GB-2266822-A (GB)
Title: Speech coding
Inventor: FREEMAN DANIEL KENNETH
IPC: G10L19/083
Filed: 1991-12-20
Abstract: In a codebook excited speech coder, speech is analysed (200) to produce coefficients of a synthesis filter and (203, 204) the parameters of a long-term prediction filter (LTP) and a codeword indication one of a set of excitations (stored in 205), the results being transmitted to a receiver where they can be used to resynthesise the speech. The LTP and excitation analysis involve computation (224) of impulse response products (stored in 301, 302). Computation of new products is performed by adding additional terms to products already formed. Multiplication of these products by excitation terms is performed using a pointer table (303) storing precalculated addresses of locations in the store (301, 302). If some excitations are shifted versions of others, some addresses can be obtained by modifying other addresses. The LTP analysis (203) may include selection between a simple delay prediction and a prediction consisting of the sum of two differently delayed terms, to provide improved predictor delay resolution.
