Patent GB-2235354-A (GB)
Title: Speech coding/encoding using celp
Inventor: MOULSLEY TIMOTHY JAMES
IPC: G10L19/12
Filed: 1989-08-16
Abstract: A speech coding system of the code excited linear prediction (CELP) type comprises means (24,26) for filtering digitised speech samples to form perceptually weighted speech samples. Entries in a one-dimensional codebook (110) comprising frame length sequences are filtered in a perceptually weighted synthesis filter (28) to form a one-dimensional filtered codebook (38). The filtered codebook entries are compared with the perceptually weighted speech signals to obtain a codebook index which gives the minimum perceptually weighted error when the speech is resynthesised. Using a one-dimensional codebook (110) reduces the amount of computation which is required compared to using a two-dimensional codebook.

Title: Vent control device
Inventor: PHILIPSON JOHN
IPC: F23L13/00
Filed: 1989-12-13
Abstract: A vent control device (28) in a furnace flue (18) reduces the draft to a predetermined level and thus reduces heat loss from the furnace through the flue. The device defines a flue gas passage, a flue gas inlet (36) and a flue gas outlet (34) adapted for engaging respective open-end portions (40, 38) of a furnace flue (18), and an intermediate portion (42, 44) of greater cross-sectional area than the inlet (36). The intermediate portion includes two apertured restriction members, (50, 52) misalignment of the apertures (62, 64) of the respective members reducing the flow area of the device from a maximum area, available when the apertures are aligned. By measuring the positive static draught of the flue during positioning of the restriction members, the draught of the flue can be adjusted to a predetermined level. <IMAGE>

Title: Securing paper to selective printer platens
Inventor: PARK KEUN-YONG
IPC: B41J13/22
Filed: 1990-06-15
Abstract: In a selective printer of the kind in which the paper is clamped to a platen drum for transport past a printhead H (e.g. in multicolour thermal printers of the kind used for printing video pictures) the clamp comprises a bar 23 extending the length of the platen, which bar is secured to the platen periphery at each end by a respective leaf spring 21, and the arrangement sufficiently biassing the bar as to grip the paper between it and the drum D. At each end of the platen is mounted a pawl 30, which is overridden by the edge 23b of the clamping bar during printing (i.e. when rotating anti-clockwise as shown by the arrow). To insert or release paper, the drum is rotated clockwise so that the paw engages under the edge 23b, thereby forcing the bar away from the platen, and also causing the edge 23b to bear on a switch S1 to start a paper exchanging mechanism which operates in conjunction with a paper sensor S2. Upon insertion of fresh paper, the stops 24 on the leaf springs align the paper leading edge. <IMAGE>

Patent GB-2262405-A (GB)
Title: Transmitting video signals with reduced horizontal and vertical blanking periods
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: H04N7/00
Filed: 1991-12-09
Abstract: Horizontal and/or vertical blanking intervals can be reduced or completely eliminated from a video signal by arranging for a FIFO buffer 24 to have a faster input clock rate (input PLL 28) than its output clock rate (output PLL 32). This provides a digital video signal for transmission or the like which has a reduced data rate since the lines (and/or frames) of the video data are expanded to fill the periods previously allocated to the blanking intervals. On reception, the blanking intervals can be restored for processing or display of the video signal by an inverse technique, data being written into a buffer at a slower rate than that being read out, the beginning of read out from the buffer being delayed until the required blanking interval has elapsed. A similar technique can be applied to modification and optimisation of inconvenient blanking intervals. <IMAGE>
Patent GB-2263570-A (GB)
Title: Drug reminder
Inventor: TAGG JAMES PETER
IPC: G08B21/24
Filed: 1991-12-31
Abstract: An improved reminder means comprises an alarm clock which can be deactivated or held-off by sensing changes in the ambient conditions. It has sensors [1-3] which detect changes in the ambient conditions (mainly light and sound) and switches which allow the user to interact with the device. A timer [4] provides inputs to the control electronics [5]. The control electronics may be programmed for differing frequencies of reminder. The control means (typically a micro controller) decides whether to suppress or activate the reminder based on the ambient conditions. For example, if the device is in a dark place such as a bag or coat pocket it will not sound its alarm until the bag is opened and the device is presented to the light. The reminder is given using the output means [6] (usually an piezo electric sounder) which may on occasions be used as a sensor as well. A power supply [9] is needed and may be a solar cell or battery. In preferred embodiments the solar cell provides the optical sensing facility. <IMAGE>

Further similar sections may be applied one on top of the other and the composite pile thereby formed after the application of each further pile section is driven to the required depth. <IMAGE>

Title: Kerb system and method of installing a kerb
Inventor: OTTERSON JOAN
IPC: E01C11/22
Filed: 1993-07-29
Abstract: A kerb system (1), used to fabricate a kerb between a path (4) and a road (5), comprises a track member (2) surmounted by a row of shorter kerb units (3). The kerb units (3) are removable to permit access to a longitudinal channel (7) contained in the track member (2). A side wall (8) is used to guide the laying of the top material layer (17) of the road (5) and also to ensure that the top material layer (17) does not stick to the kerb units (3) and thereby make their subsequent replacement difficult. A method of installing a kerb between a path for pedestrians and a road for vehicles, by using a kerb system comprising a track member having a first upwardly projecting side wall and a plurality of kerb units mountable on the track member, comprises the steps of: installing the track member between the path and the road, with the first upwardly projecting side wall adjacent to the road, and including setting a top edge of the first side wall to be at or above a desired level of the interface between the kerb and the top surface of a top material layer of the road; laying the top matenal layer of the road, so that the interface between the kerb and the top surface of the top material layer is at the desired level; and      mounting the kerb units in a row on the track member. <IMAGE>

Filed: 1994-03-21
Abstract: The flexible protective cladding comprises a plurality of flexibly linked annuli (11) in which each annulus carries a plate (12) whose periphery overlaps the edge of the associated annulus. The links (2) between annuli permit movement up to the diameter of one annulus in the plane formed by the annuli. The plates on alternate annuli are located on opposite surfaces of the annuli. Gaps between upper and lower plates may be filled by discs 16. Each annulus may be linked to four other annuli disposed at approximately 90 DEG  intervals around its periphery. The links between annuli in assembled cladding may pass transversely across each other at regular intervals. Alternatively the links may be formed as simple loops, each one associated with a single annulus, whose ends are attached to the ends of other similar loops to link the annuli. The links may take the form of straps which thread through two annuli and whose ends are joined by a single fixing element. <IMAGE>
