Patent GB-2293288-A (GB)
Title: Conversion between analogue and digital signals
Inventor: MATSUSHIGE TAKASHI
IPC: H03H17/00
Filed: 1994-09-15
Abstract: Analogue to digital (A/D) and digital to analogue (D/A) converters perform the required conversion at a higher sampling rate (e.g. 64Fs) and a lower resolution (e.g. 1 to 4 bits) than the actual sampling rate (Fs) and resolution (e.g. 16 bits) of the required digital signal. The oversampled low resolution signal is generated by oversampling the input digital signal (for D/A conversion) or is decimated, 20, to generate the required output digital signal (for A/D conversion). The oversampling or decimation filters are switchable between two modes of operation, in which different signal delays are imposed by the filter. Thus a lower quality, but shorter delay, filter can be used in converters in the signal path for an artist's foldback signal. This can reduce the subjectively disturbing effects of long conversion delays in the foldback signal path. A plurality of audio channels may be processed eg for recording, by apparatus which is operable in at least a first mode in which Nö channels are processed at a sample rate of Fs1, and a second mode in which N2 channels are processed at a sample rate of Fs2, where the product of N1 and Fs1 is equal to the product of N2 and Fs2. Specifically N1 = 2N2 and 2Fs1 = Fs2. <IMAGE>

Title: Sewing elastic tape to garment edges
Inventor: NAVLYT DAVID M
IPC: D05B19/16
Filed: 1994-09-30
Abstract: When sewing edges of successive garment blanks (10) with elastic tape severing of the tape being fed is controlled automatically in dependence on the sewing operation so that the ends (52, 54) of the tape lie inwardly of the ends of the edge of the blank to minimise waste of tape. In particular the trailing end of the garment edge is detected optically and the elastic is severed after a predetermined number of stitches. The elastic tape feeding and severing device is located below the work support of the sewing machine. A binder tape may be folded round the blank edge and elastic tape or the blank edge may itself be folded. The elastic tape may lie under the blank edge. <IMAGE>

Title: Self-propelled work machine
Inventor: ROBERTSON ALFRED FYFFE
IPC: A01G23/08
Filed: 1996-06-18
Abstract: A self-propelled work machine is based on a conventional tracked excavator (12) and, as shown, when modified for use as a timber harvester the conventional excavator arm has been removed and replaced by a parallel motion timber crane (24) mounted on the slewable platform (16) by means of a tilting crane boom (32) carrying a secondary slewing mechanism (34). The secondary slewing mechanism (34) enables a harvesting head (26) to be steered between standing trees for thinning to be carried out without the overhanging back (22) of the platform (16) colliding with trees. Controlled tilting of the crane boom (34) enables tilting of the secondary slewing axis to match the slope of ground on which trees are standing, enabling faster working with less damage.

Title: Image storage and retrieval
Inventor: HORNE ROBIN EDMUND NEWTON
IPC: H04N5/44
Filed: 1996-04-10
Abstract: In order to store and retrieve one or more images in the form of electromagnetic signals, a processing apparatus has two signal routes. The first route (10, 14, 50, 22, 20) passes the signal from an input (12) to a output (24) without storage. The second route (10, 14, 50, 32) passes the signal to a solid state storage device (30). The passage of signals via the secondary route (10, 14, 50, 32) is triggered by a suitable trigger (51), which may be user-controlled or automatic. The, or part of, the signal representing one or more images is stored in the solid state storage device (30) and may subsequently be retrieved via the output (24). The retrieved signal from the solid state storage device (30) then replaces other signals at the output (24). In order to keep the apparatus of the present invention simple, data representing the signal passed to the solid state storage device (30) may be passed sequentially, stored sequentially and output in the same sequence. There is then no processing of individual bits of the data, merely storage.
