Abstract: A learning aid comprises more than one percussive instrument, each instrument having a resonator body co-operating with either a drum head or a xylophone key, and the whole aid being capable of providing a variety of sounds. Each drum body preferably has a characteristic cross-section and colour, for example five resonator bodies 4 can be mountable in base 9 and provided with correspondingly shaped drum heads 8 to form separate instruments 6 producing different sounds by virtue of different lengths of resonator body; instruments 6 can if desired be used as free standing items. Similarly, different lengths of resonator body (5), Fig 5 (not shown), co-operate with colour coded xylophone keys (7) in a pentangle arrangement, and can be tuned to provide the same pitch as the correspondingly coloured drum elements. A child can associate sounds with the shapes or colours, aiding in pattern recognition, manipulation of objects, sorting and classifying, etc. If used with instruction cards, Figs 6 to 11 (not shown), elements of counting, and simple music making can also be achieved.
Patent GB-2333409-A (GB)
Title: Wavelength monitor for optical WDM signals
Inventor: BRAUN DAVID M
IPC: H04B10/07
Filed: 1998-11-03
Abstract: A wavelength monitor 20 detects wavelength drifts of component channel signals within multi-wavelength light signals 21. Multi-wavelength light incident on the wavelength monitor is cascaded along a multipoint travel path. Within the travel path, the component channel signals are incident on a series of wavelength discriminators 22a-22h arranged on an optically transmissive member 26. The optical transmission through each wavelength discriminator varies monotonically according to variations in the wavelength of the predetermined channel signal. Each selectively transmitted channel signal is intercepted by a detector 24a-24h which produces an output current that is mapped to corresponding signal wavelengths. Alternatively the wavelength discriminator includes a dispersive element that maps the applied channel signal to spatial locations dependent upon the signal wavelength. The dispersed signal is intercepted by a split-detector (34, Fig. 5 not shown) responsive to the spatial location of the dispersed signal. The output currents produced by the split-detector are used to monitor wavelength deviations of the incident channel signal from the predefined channel wavelength.

Patent GB-2341022-A (GB)
Title: Data input-output circuits that selectively invert bits to save power
Inventor: CHOI JUNG-HWAN
IPC: G06F3/00
Filed: 1999-08-09
Abstract: A plurality of bits (RDAT) is output if more of the plurality of bits are of a first logical value than a second logical value, and the plurality of bits inverted is output if more of the plurality of bits are of the second logical value than the first logical value. An indicator (XCON) also is provided as to whether the plurality of bits or the plurality of bits inverted are output. Thus, for example, if more of the bits are of the logical value that causes high current consumption, the output bits are inverted so that the bits can be output with reduced current consumption. Upon receipt, the plurality of bits and the indicator are received. The plurality of bits is retained if the indicator is of a first value and the plurality of bits is inverted if the indicator is of a second value. Thus, the power consumption of the data input-output circuits may be reduced. The technique may be applied to memories with open-drain outputs.

Title: Carbonyl sulphide fumigant and method of fumigation
Inventor: DESMARCHLIER FRANCIS JAMES MIC
IPC: A23B9/18
Filed: 1993-01-15
Abstract: The gaseous chemical compound, carbonyl sulphide, has hitherto been unknown as a fumigant for the control of insects and mites. Experiments have shown conclusively that carbonyl sulphide can be used as such a fumigant, with fumigation properties comparable to those of phosphine and methyl bromide. The effectiveness of carbonyl sulphide against insects (both adult and immature stages), mites, termites and moulds is demonstrated. In addition, its low absorbtion by grain, lower flammability than phosphine, lack of influence on seed germination, and apparent environmental safety make carbonyl sulphide particularly beneficial as a fumigant of stored grain. It may also be used to fumigate other stored produce (including perishable foodstuff), soil, timber and spaces (such as buildings) and any material likely to be infested by insects or mites, or act as a source of such infestation.
