Title: Direct frequency synthesiser
Inventor: SAUL PETER HENRY
IPC: H03K4/06
Filed: 1988-04-07
Abstract: A direct frequency synthesiser comprises an accumulator or adder including a multiplicity of individual adder elements appertaining to the respective bits of a frequency setting input signal to be applied to the adder in operation of the synthesiser. Latches associated with the adder elements are operable in response to clock pulses to cause the adder to provide an incrementally varying added digital signal, Fig 2(a) which is applied to the gates of two sets of gates together with the outputs Figs 2(c), 2(d), from two D type flip-flop or bistable devices. The flip-flops or bistable devices have opposite polarity triggering characteristics, are connected in parallel, and have applied thereto the output from the adder element appertaining to the most significant bit of the frequency setting input signal Fig 2(b). The digital outputs from the respective sets of gates, Figs 2(e), 2(f) correspond to triangular waveform analogue signals in quadrature phase relationship with one another and are fed to respective digital-to-analogue converters which provide respective signal outputs at the requisite frequency set by the frequency setting input signal. <IMAGE>

Patent GB-2518338-A (GB)
Title: Multi-function adaptive processor
Inventor: RICKARD ROBIN PAUL
IPC: H01Q3/26
Filed: 1988-11-30
Abstract: An adaptive processor for use with multiple input signals from an array of antenna elements is designed to be used in a wide range of applications with only minor changes to component values and data stored in an application PROM. The processor is operated to minimise output power subject to a weight constraint. The control algorithm employed is a weight update correlation loop algorithm of the form Wn = (1-1Ïµ)Wn-1 - ÂµEnSn where Wn is the updated weight, Ïµ is an integration loss factor, Âµ is the update gain, En is a complex input (element) signal and Sn is a complex sum signal. The integration loss factor is varied for each input signal and is controlled as a function of the input signal power level. Preferably the control algorithm is power normalised, that is the update gain factor is variable and inversely proportional to the power of the respective input signal. The use of a variable integration loss factor enables a fixed absolute sensitivity (turn-on) threshold to be maintained. The power normalised algorithm is preferably implemented using two automatic gain control (a.g.c.) systems and logarithmic coding of power levels to reduce system complexity.
Patent GB-2212643-A (GB)
Title: Radio communication apparatus
Inventor: TSUNODA KAZUYUKI
IPC: H04B7/26
Filed: 1988-12-23
Abstract: In a radio communication apparatus for selectively receiving call signals indicative of respective call numbers, a decoder 17 processes the received signal into a common call tone signal representative of reception of the received signal regardless of the call numbers. A tone generator 21, 20 generates a common tone in response to the common call tone signal to indicate reception of one of the call signals. When a manually operable switch 22 is operated, the decoder 17 makes the tone generator stop generation of the common tone and classify the received signal into one of individual tone signals corresponding to the respective call numbers. Subsequently, the decoder makes the tone generator 21, 20 generate a particular tone indicating the call number of the received signal in question. When the switch 22 is again operated, the decoder makes the tone generator stop generation of the particular tone. <IMAGE>

The gases enter the bed 3 via surface region 11, flow through aperture 18 below the baffle 17 and exit from the bed via surface region 12. The restricted flow path encourages more gas/bed material contact. The container construction avoids the necessity of a gas permeable wall at the 'hot' end of the regenerator. <IMAGE>
Patent GB-2229667-A (GB)
Title: Petal mould and moulding process
Inventor: RICHARDS TIMOTHY JOHN
IPC: B29C33/50
Filed: 1989-03-07
Abstract: A mould made from flexible moulding material e.g. silicone rubber consists of a number of leaves or petals which are flexibly pivotable about a common base. The mould is particularly useful in the casting of thin walled fine detail objects where minimum air entrapment is required e.g. a model plaster building, and also facilitates the mould release of undercut article configurations. During mould filling with a liquid material, one or an opposed pair of mould sides (3) are sealingly engaged between an opposite pair of the mould sides (2) which are maintained at a constant separation distance and act as a seal against the sides (3), as at least one of them is progressively inwardly flexed towards a closed position during filling with the liquid, so that air can move towards the liquid surface and entrapment against the mould sides is avoided. Article release is effected by outward flexing of the mould walls. <IMAGE>

Title: A pair of seal members of hard material having a low friction coefficient
Inventor: KNAPP ALFONS
IPC: F16J15/34
Filed: 1988-10-13
Abstract: A pair of seal members of hard material such as a pair of small plates which control the fluid flow through a faucet. The first seal member is made of silicon carbide, preferably formed by a process of siliconizing a carbonaceous semi-finished form. The second seal member is made from a material which is at least moderately hard, capable of receiving a precise finish, and is covered by a thin layer of harder material - silicon carbide or another carbide, a nitride, or carbon with a cubic crystallographic lattice structure - applied by physical or chemical deposition by vapor. This configuration results in a low friction coefficient even in the absence of lubrication, prevents excessive adhesion among the parts with highly polished surfaces, it assures smooth operation over long periods of time even if the seal members are subjected to high temperatures, and an excessive amount of friction is prevented upon initial separation.

Title: Cat doors
Inventor: KIRK CHRISTOPHER PETER
IPC: E06B7/32
Filed: 1989-09-22
Abstract: A cat door is made by injection moulding a frame 10 so as to have a compartment 12 below an opening 11 divided therefrom by a resilient sill 13. In the opening 11 a flap 20 hangs vertically from pivot means whereby it can swing about a horizontal axis 21 near its upper edge. Freedom of the flap 20 to swing in either direction can be restricted by rotation of a locking unit 26, which has disc portions 28 and 29 projecting through a slot 16 in the sill 13 so as to be capable of entrapping the lower edge 31 of the flap between them. The locking unit is assembled with the frame by deforming the sill 13. Segments of the peripheries 20 of the disc portions 28 and 29 have been removed to permit rotation of the locking unit to positions in which the flap 20 is free to swing in one or in both directions. The locking unit also comprises a projection 30 with straight sides corresponding with different peripheral regions of the disc portions. When rotated to bring successive straight sides of the projection 30 into parallelism with the underside of sill 13 the latter is stressed, providing a detent mechanism for location of the peripheries of the disc portions in different locking or unlocking relation to the flap 20. <IMAGE>

Title: Signal demodulation device
Inventor: SATO KOICHI
IPC: H04L27/233
Filed: 1991-04-22
Abstract: A signal demodulation device includes a change point sensing circuit (12) which senses a change point of the envelope of a DPSK signal, and a range setting circuit (26) which generates a gate pulse (E) corresponding to a period in which the DPSK signal cannot be changed. The output signal of the change point sensing circuit (12) and the gate pulse (E) are input to an AND gate (27) so that a trigger prohibition signal (G) is obtained. The trigger prohibition signal (G) and the output signal of the change point sensing circuit (12) are input to a NOR gate (32) so that a trigger pulse corresponding only to a normal change point of the DPSK signal is generated, whereby correct DPSK demodulation data is obtained. The signal demodulation device may be used in a still video camera where video signals and DPSK coded data signals are recorded on and read from a floppy disk 2. Use of the range setting circuit (26) eliminates the effect of dropouts on the DPSK demodulation data. <IMAGE>
