Title: Waste bins
Inventor: BARTLE ANDREW DAVID
IPC: A61B19/02
Filed: 1991-12-10
Abstract: A waste bin 1 for medical waste comprises a lower part 2 and an upper part 3, each of which is formed by folding from a separate cardboard blank. The lower part 2 has an open top and incorporates a bottom wall and four side walls 5 defining an inner space for receiving a liner to be supported by the side walls 5. The upper part 3 has an open bottom and incorporates four side walls 6 overlapping the side walls of the lower part so as to trap the upper portion of the liner therebetween. The upper part 3 also has a lid 7 which is pivotable between open and closed positions and which, when open, permits introduction of waste into the bin. The trapping of the upper portion of the liner between the side walls of the two parts of the bin reliably prevents the liner from becoming dislodged in such a way as to allow leakage in use of the bin. Furthermore the bin itself may be designed to be disposable with the waste. <IMAGE>

Title: Tyre building apparatus with piston/cylinder actuated segmented drum
Inventor: MORI KATUMI
IPC: B29D30/24
Filed: 1991-12-23
Abstract: A tyre building apparatus has a pneumatic piston/cylinder actuator for radially moving arcuate drum segments (32) between an expanded, building position and a collapsed, removal position. The actuator comprises a piston (50) fixedly mounted on the drum shaft (34) and a reciprocally movable cylinder (60) mounted on the piston. An annular primary chamber (64) is defined around the shaft on one side of the piston by one end wall (62) of the cylinder. An annular pressure accumulating tank (52) is provided on the shaft on the other side of the piston. An annular secondary chamber (68) is defined around the tank (52) by the other end wall (66) of the cylinder. The secondary chamber (68) is in communication with the pressure accumulating tank through an opening (70). A check valve (72) is provided in the piston to permit air flow from the primary to the secondary chamber. The cylinder (60) is drivingly connected with the drum segments (32) through mechanical links (88). Due to a difference in area of the end walls (62, 64) of the cylinder, coupling via line (46) of pressurised air to the actuator will cause the cylinder to move (Fig. 6) in a direction tending to inflate the primary chamber (64) while deflating the secondary chamber (66). Decoupling the air supply allows pressurised air in chamber (68) to reverse the movement (Fig. 7) of the cylinder, air flowing from tank (52) into chamber (68). <IMAGE>

Title: Control of access to data records.
Inventor: O'FLATHARTHA PEADAR
IPC: G06F21/80
Filed: 1991-12-27
Abstract: - After data from a record in a database is transmitted to a memory circuit (5), only write instructions are disabled (7) so that other processors may access the record (2) to read the data and use it. After processing of the data in the memory circuit (8), read instructions are also disabled (9) and the processed data is written to the record (10). This operation takes only a fraction of a second and immediately afterwards, the read/write controller is directed to enable both read and write instructions (12). <IMAGE>

Title: Photochromic filter assemblies
Inventor: FOLEY JOHN PATRICK
IPC: G02C7/10
Filed: 1993-03-24
Abstract: An optical device 10 (e.g. a human eye) is protected from very high levels of illumination 12 by photochromic filters 11A, 11B, etc which progressively attenuate the transmitted visible light. The filters are activated by the UV content of the illumination which is intercepted by a 50% UV beamsplitter 13 to permit the front faces of the filters to be irradiated by UV light whilst their rear faces are similarly irradiated by UV light directed by the beamsplitters, a fold mirror 14 and one or more UV bcamsplitters 13B, 13C, etc. Each filter is of limited thickness for maximum efficiency being equal to the penetration depth for the UV activation wavelengths. In other embodiments one or more double-sided filters is used. <IMAGE>

Title: Growth of diamond films on silicon substrates with application of bias to substrate; tessellated patterns
Inventor: SOUTHWORTH PAUL
IPC: C23C16/27
Filed: 1993-08-27
Abstract: A method for growing an oriented diamond film on a single crystal silicon substrate comprises preconditioning the surface of the substrate by exposing the surface of the substrate to a carbon-containing plasma, subjecting the preconditioned surface to electrical bias, eg a negative DC bias, to effect nucleation of the substrate surface for oriented diamond crystal growth while monitoring the completion of nucleation over the surface of the substrate and depositing crystalline diamond on the nucleated surface from a carbon-containing plasma. The resulting structure comprises a crystalline diamond film on the silicon substrate characterised by oriented columnar diamond crystals which form a substantially uniform tessellated pattern. In practice, the columnar crystals normally have a generally quadrilateral shape whose sides are mutually aligned. The end of the nucleation phase may be detected by determining when the apparent temperature of the surface of the substrate markedly increases. The substrate may be supported on a platform of a refractory metal, eg Mo, W, Ta, which in turn is supported on a graphite susceptor which includes radiofrequency heating means.

Title: Noise reduction in pulse radar
Inventor: MITSUMOTO MASASHI
IPC: G01S7/292
Filed: 1994-07-26
Abstract: A digital, coherent pulse radar incorporates inphase (61, fig 1) and quadrature (62) detection. Returns from various range bins are fed to respective noise reduction sections (15-1 to 15-L, fig 1). Each noise reduction section 15-i comprises an integrator 16 which integrates the returns from a respective range bin, the number of returns N(i) integrated being different for each range bin (eg equal to the fourth power of the range R(i)). This allows a rapid response to targets close to the radar, where noise is less of a problem, whilst maintaining a good signal-to-noise ratio at longer ranges, where a rapid response is less important. The integrated returns are divided into N Doppler channels, each with its respective amplitude detector 12-1 to 12-N, and thence to a CFAR detector 22. The number of reference cells used in the CFAR section may also be increased with range, and the threshold may be variable. The integrator 16 may be replaced by a FFT (26, fig 10), in which case the variable N(i) becomes the number of points used in the FFT. <IMAGE>
