Patent GB-2083934-A (GB)
Title: Electronic Game-playing Machines
IPC: G07F17/34
Filed: 1981-08-20
Abstract: A coin-released fruit machine incorporates a single-pole two-way switch 1 for initiating rotation of the reels on playing of a game. On depression of a button a movable contact 4 of the switch 1 is moved away from a fixed contact 2 thus causing a counter 6 to start counting clock pulses. The counting of the counter 6 is stopped when the movable contact 4 engages a further fixed contact 3. The resultant count value appearing at the output 9 of the counter 6 will be proportional to the time taken for the movable contact 4 to move between the two fixed contacts 2 and 3, and is hence dependent on the force applied to the button against the action of a spring. This count value is used to control some aspect of the game played so as to introduce or appear to introduce an element of skill into the playing of the game. The two-way switch may be replaced by two one-way microswitches connected in series. <IMAGE>

Patent GB-2102233-A (GB)
Title: A technique for the extraction of doppler spectra from radars
Inventor: BAGWELL DAVID JOHN
IPC: G01S13/53
Filed: 1982-06-01
Abstract: The invention is a technique and method of isolating frequency shifted or phase varying components from a single relative to a reference carrier. This technique has particular application to the extraction of Doppler shifted signals in pulse radar returns. A number of reference frequency carrier waves either sinusoidal or of discrete state are generated with equal distribution of phase over one cycle. The data signal is mixed with each of these carriers in sequence and the result filtered to isolate the difference component which is offset from and coherent with the reference carrier. Quadrature offset outputs are obtained by using two mixers fed by quadrature reference carriers, a common set being available for multiples of four phase steps. The technique overcomes the d.c. drift associated with on-frequency mixing and the need for high resolution synthesisers in conventional offset mixing systems. <IMAGE>

Title: Process and arrangement for the observation of the biological processes taking place in plants
Inventor: BOHATKA SANDOR
IPC: G01N33/497
Filed: 1983-02-02
Abstract: The biological processes taking place in plants and plant parts under natural conditions or as affected by different chemicals and agronomical means are observed by measuring the gases in free or dissolved state in the plants and taking part in the metabolism. A gas sampler is placed into the plant or on to its surface and a sample of the gases obtained is passed to a gas detector such as a mass spectrometer. The gas sampler taken from the plant is a small amount which does not disturb the biological processes of the plant. Rapid changes, even changes of some seconds can be measured by the process of the invention.
Patent GB-2116277-A (GB)
Title: Connector for fluid communication
Inventor: DAVIS BRIAN EDWARD
IPC: F16L29/00
Filed: 1983-02-21
Abstract: A valved coupling for establishing fluid connection between two separate but couplable elements has the parts that meet together to establish that connection. This is achieved by forming the faces (4, 24) of obdurators which meet face-to-face upon coupling to be exactly the same as each other in profile extent and boundary shape, the same being true of the marginal faces (9, 22) around the obdurators which belong to valve members (6, 16) coacting with the latter, the obdurators and valve members being relatively movable. Furthermore, each transition from obturator face to marginal face is smooth (collinear) when the elements are uncoupled from each other. An internally threaded sleeve 20 holds the elements in their coupled elements come together with the obturators and valve members in register, respectively. <IMAGE>
Patent GB-2121630-A (GB)
Title: Improved inverter circuit
Inventor: BARDOS PETER ANDREW
IPC: H02M3/335
Filed: 1983-03-17
Abstract: An inverter comprises a transistor oscillator including a transistor (20) connected to a coupling transformer (10) which is arranged to provide oscillation maintaining feedback from a winding (11) connected to the collector of the transistor (20) to a winding (13) connected in the base circuit of the transistor (20). A voltage limiting circuit (41', 70) is connected to a further winding (12b) of the transformer and acts to limit the overswing voltage appearing at the collector of the transistor (20) by providing a voltage sink effect which controls the mark-space ratio of the transistor (20) by maintaining the non-conduction period until the transformer (10) has reset. An inhibiting circuit (150) acts to clamp the voltage of the node where 71' 74 and 154 meet for a short preset period after the end of the conduction period of the transistor (20) to prevent spurious turn-on of the transistor during that period due to voltages in the winding (13), and thereby to allow a greater range of (i.e. lower) mark-space ratio to be utilised <IMAGE>

Filed: 1983-10-24
Abstract: A magnetic core for a transformer, inductor, etc. is separable into two parts for assembly with an electrical winding and after assembly is secured together by a clip (for example, an EK-core or an EI-core). The clip comprises two interfitting parts 2 that together encircle the core, and at least one of the parts is resilient and is deformed when the parts are assembled to provide a biasing force urging the parts of the core together; e.g. in the case of a sheet metal clip, the base may be bowed inwardly. Each of the parts of the clip is shaped to engage and hold the corresponding part 1 of the core, independently of any other parts, and this provides the sole means by which the laminations of the core part are held together. <IMAGE>
