Title: Hydraulic control or testing apparatus
Inventor: HOWDEN CHRISTOPHER
IPC: G05D15/01
Filed: 1989-04-22
Abstract: A hydraulic control or testing apparatus for applying a selected high pressure or selected force, for example to a test piece, comprises a fluid pressure actuator (11) to be supplied, in use, with an hydraulic pressure fluid, a fluid reservoir (14), and a pump (16) interconnecting the reservoir and the actuator.

Patent GB-2248513-A (GB)
Title: Speaker verification
Inventor: CAREY MICHAEL JOHN
IPC: G10L17/00
Filed: 1991-09-30
Abstract: Speaker verification is important in such applications as financial transactions which are to be carried out automatically by telephone. False acceptances of a speaker cause serious problems but so do frequent false rejections in view of the annoyance caused. Some of the problems of speaker verification are reduced in the invention by forming Hidden Markov Models (HMMs) for each of a mumber of words using features of utterances of these words from a large number of speakers. These models are known as world models. In addition for every person whose speech is to be recognised, one HMM is formed for each of the words as uttered by that person. These models are known as personal models. In verification a person is prompted to repeat a string of isolated or connected words (15) and features from each of these words are extracted (16). Next the probabilities that these features could have been generated by the world models for these words and by the personal model of that person are calculated, respectively (17 and 18) and these probabilities are compared (19) for each word. A decision (23) on verification is based on a poll (22) of these comparisons.

Title: Restricting the build-up of ground-emanating gases under or in a structure
Inventor: NICHOLS PAUL IAN
IPC: E02D31/00
Filed: 1993-03-22
Abstract: A static ground-supported structure (10) is provided with a system for restricting the build-up of ground-emanating gases such as radon under or within the structure. The system includes a pump (12) situated, for example, in a loft void (11) of the structure and taking on a supply of air relatively free of said gases. The pump (12) supplies air at a pressure above ambient into a pipe (18) that takes it down to air-diffusion means (28) located in the ground (5) beneath the structure. The pressurised air diffuses into the ground and reduces the upward flow of gases. A sensor system (41 to 44) sensing the build up of ground-emanating gases, may also be provided to control operation of the pump. The pump (2) of the system may additionally serve to provide ventilation air into the structure. <IMAGE>

Title: Motor vehicle having ground effect producing aerodynamic surfaces
Inventor: MURRAY IAN GORDON
IPC: B62D37/02
Filed: 1993-07-14
Abstract: The underside of a car 10 defines with the road surface a venturi throat 4 and a diffuser 2. The airflow through the venturi throat 4 provides a downforce F which acts on the vehicle through the aerodynamic centre of pressure (C.O.P).
