Title: A spectrum analyser and other apparatus for detecting at least one particular frequency component in an electrical signal
Inventor: WISBEY PHILIP HENRY
IPC: H03H9/02
Filed: 1981-09-12
Abstract: A spectrum analyser for analysing an electrical signal into its different frequency components, first converts the signal into surface acoustic waves. These surface acoustic waves are separated spatially into different frequency components by, for example, using an interference effect (Fig. 1 not shown) or by using a refraction technique Fig. 4. Referring to Fig. 4 the signal to be analysed is applied to a transducer 16A, 16B and 17, which launches surface acoustic waves along a silicon member 15. Different frequency components of the surface acoustic waves are focussed by a dispersive lens 22 onto respective different focal spots 18 and generate voltages in a piezoelectric layer 20. These voltages are rectified by diodes formed integrally in the member 15 to produce rectified D.C. outputs at terminals f1, f2, f3, and f4. <IMAGE>

Title: Swash-plate drive
IPC: F16H19/08
Filed: 1981-10-08
Abstract: A swash-plate drive has an arcuate drive Plate 2, 12 either semi- circular or circular whose edge engages a swash plate 3. The swash plate 3 is mounted on a universal joint 7, and bearing 8, supporting a driven shaft 9. In use, the arcuate plate is oscillated and its edge engages the face of the swash plate off-centre, sliding across the swash plate so as to engage one side and then the other as the motion of the arcuate plate changes from one direction to the other. As a result the swash plate has a unidirectional rotation and this rotates the shaft 9. The arcuate plate is permitted a small amount of lateral movement and in the embodiments described with reference to Figs 5 to 7 (not shown) it is also capable of lateral tilting. The swash plate has a wobble during operation, and this is less in the second embodiment than in the first. The arcuate plate is of paramagnetic material and the swash plate incorporates a magnetic core. Means for enhancing the frictional engagement of the arcuate plate and swash plate may include intermeshing gear teeth or laterally spaced rubber rings located on the arcuate plate and separated by a metal band which provides for magnetic attraction between the arcuate plate and swash plate. <IMAGE>

Patent GB-2113044-A (GB)
Title: Telephone ringing signal generation
Inventor: SWEET ANTHONY WILLIAM
IPC: H04M19/02
Filed: 1981-12-03
Abstract: In our Application No. 8005000 (GB 2071461A) we have described a telephone line circuit which includes a programmable (i.e. adjustable) voltage source (VVS) connected in series with the line in one wire (B) thereof, and also a constant-current source (PCR) connected between the two line wires. Line conditions are monitored, and the line supply as defined by these two sources is so controlled in accordance with line conditions as to minimise power dissipation. Thus for a short loop, voltage can be reduced. The present invention relates to the supply of ringing current in such a circuit. The ringing current is applied from a low-level supply to the variable voltage source (VVS), so that it is amplified and modulates the DC line feed. In addition there is a further controlled current device (RS) on the line side of the voltage source (VVS) which is enabled when ringing current is present. This device by virtue of the current it diverts during ringing regulates the AC ringing current level as applied to the line. <IMAGE>

Patent GB-2120864-A (GB)
Title: Air ionizers
Inventor: MIDDLETON CHARLES DENIS
IPC: H01T23/00
Filed: 1982-05-05
Abstract: The invention uses a free-running rotor as a means for ionising air instead of the fixed needle or needles used in known devices. A high negative voltage is led to a rotor 5 having discharge points directed to impart rotation by reaction from the stream of ionised air leaving the points. The ioniser can be seen to be working satisfactorily, and the concentration at the points is reduced because they are moving away from the ionised air, minimising the undesirable production of ozone which arises from a visible discharge. <IMAGE>

Patent GB-2117366-A (GB)
Title: Catalyst and method of its preparation
Inventor: ROBINSON JOSEPH GORDON
IPC: H01M8/06
Filed: 1983-02-15
Abstract: A novel catalyst comprises a highly porous silica having a layer of nickel bonded onto up to 50% (preferably 25%) of the surface of the silica matrix. The nickel is chemically bound into the surface by causing the surfact to react with a nickel compound. For instance nickel chloride is deposited on the matrix and caused to react therewith by treatment with a strong base. The catalyst will find use in converting an alkanol, especially methanol, to hydrogen. Thus methanol can be used to store hydrogen prior to its use as an alternative energy source.
