Title: A multi-layered silver halide color photographic material
IPC: G03C7/30
Filed: 1981-09-02
Abstract: In order to overcome problems associated with providing a sharp image without causing desensitization, a multi-layered silver halide color photographic material wherein blue-, green- and red-photosensitive silver halide emulsion layers are provided on one side of a support has a coupler in the photosensitive layer furthest from the support which, upon colour development, yields a dye having a larger molecular extinction coefficient than those of the dyes formed by the couplers in the underlying layers. Preferably the material is a 'false colour' material and may contain magenta or cyan couplers in an outermost blue- photosensitive silver halide emulsion layer.

Title: R.F. spectrum analyser
Inventor: GRATZE STEPHEN CECIL
IPC: G01R23/17
Filed: 1982-01-22
Abstract: A Bragg cell spectrum analyser capable of handling an incoming signal of more than a given bandwidth which does not require the use of several Bragg cells comprises a single Bragg cell 1 and surface acoustic wave transducers 5 and 6 to divide a single optical beam 3 into three diverging beams 8, 9 and 10. Further surface acoustic wave transducers 18, 19 and 20 are arranged to receive different frequency bands of an incoming signal from antenna 11 after being mixed at 12, 13 and 14 with different locally generated fixed frequencies f0, 2f0 and 3f0. Surface acoustic waves from the transducers 18, 19 and 20 interact with respective diverging secondary beams 8, 9 and 10 so as to diffract the latter through different angles, corresponding to the different frequency components in the incoming signal, to arrays 21, 22 and 23 of detectors which indicate what frequency components are present. Lenses are used to collimate the beam 3 and to focus the different diffracted components of beams 8, 9 and 10 onto the detectors. <IMAGE>

Title: Measurement of frequency or period of a signal
IPC: G01R23/14
Filed: 1982-02-08
Abstract: The frequency or period of oscillation of an electrical signal is determined by providing a reference signal at a higher or lower frequency; mixing at 36 the two signals to generate a beat frequency; counting at 54 the number of beat signals approximately corresponding to a known time interval; counting at 56 precisely the number of cycles of a clock frequency (such as the reference signal) occurring between the counted beat signals; and from the two counted numbers determining the unknown frequency or period. The method may be applied to a resonating crystal on which a material is deposited during a deposition process. <IMAGE>

Patent GB-2158980-A (GB)
Title: Extraction of phonemic information
Inventor: NAKATANI TOMOFUMI
IPC: G10L15/00
Filed: 1985-03-19
Abstract: When subjected to frequency analysis and plotted in a frequency spectral distribution, a voice signal typically includes a monotonously and relatively slowly changing component and a relatively rapidly changing component. For the recognition of voice sound, the relatively rapidly changing component contains phonemic information and thus is more important. In order to extract such a relatively rapidly changing component containing phonemic information from a voice signal, the voice signal is first subjected to frequency analysis to obtain a frequency spectral distribution, which is then sampled from one end to the other and then in the reversed order in timed sequence repetitively to produce a periodic waveform. Then, the thus obtained periodic waveform is filtered to remove the relatively slowly changing component thereby extracting the relatively rapidly changing component.

Title: Frequency synthesiser
Inventor: BRENNAN PAUL VICTOR
IPC: H03L7/093
Filed: 1985-12-06
Abstract: In a digital frequency synthesiser of the kind comprising a phase locked loop which includes a voltage controlled oscillator providing an output frequency, there can be a variation of the loop gain with operating frequency and efforts to avoid this variations can result in the generation of noise contributions in the output signal. The invention provides a phase locked loop having a voltage controlled oscillator (1) with variable divider (4) and phase detector (6). An output from the phase detector (6) is applied to a level shifting buffer amplifier (9) which is controlled by the same digital code as that applied to effect setting of the divider (4). This ensures a constant loop gain and low noise in the frequency output signal.

Title: Method and apparatus for extrusion and blowing of a hollow body of plastics material
Inventor: CORDIER JACQUES
IPC: B29C49/18
Filed: 1986-10-17
Abstract: An extruding die (3) produces a parson (28) in roughly the shape of the hollow body, and air is blown into the parison (28) through the die (3) until its length is equal to the length of the desired hollow body, then the blowing air is cut off and the parison vented to atmosphere through the die (3) so as to obtain a deflated parison (31). The mould (6) is closed and air at high pressure is blown into the parson (31) at a location displaced from the extrusion die, so as to obtain the moulded body (9a). This method results in a uniform thickness of the plastics material in the various cross-section of the container. The alternate admission of blowing air and the venting to atmosphere of the parison interior, through the extrusion die passage e.g. through a passages (26,27) of a pair of extrusion dies, is controlled by sequential electro- valves (23), and (21 or 22). <IMAGE>
