Title: Measuring alpha or neutron radiation using a microphone - by detecting potential developed by charges created in ionisable gas between plates
Inventor: ALLAF ABDUL KARIM SALIM
IPC: H01J47/02
Filed: 1975-12-30
Abstract: An appts. for measuring alpha radiation emitted by a source incorporates a microphone, contg. two metal plates, placed near the source. One plate, is placed opposite the source and is thin enough for the alpha radiation to pass through without appreciable attenuation. The space bounded by the plates is filled with an ionising gas. An electrical field establishes a direct potential difference between the plates. An electronic system amplifies and records as a function of time the variations in the potential V(t) developed between the plates. The appts. may be used for measuring the intensity of a neutron flux. In this case the first plate is covered with a substance which delivers alpha rays under the influence of a neutron flux. The limitations imposed in using ionising chambers and counters and the lack of precision of calorimetric methods are avoided.

Title: Two wheeled vehicle stabilisation system - uses extra weights or wheels displaced by suitable transmission without muscular effort
IPC: B62D37/00
Filed: 1976-01-23
Abstract: A one man or two man vehicle, particularly a ski bob, incorporates a balance control system employing a mechanical transmission arrangement, suitably operated by the driver, so that no muscular force is necessary. Thus to oppose the effect of centrifugal force, weights which are independent of the driver's weight and also that of a passenger can be suitably displaced. These weights are eccentric to the axis of rotation of the vehicle. Alternatively, extra outrigger wheels (14) can be raised and lowered for the same purpose. The transmission systems may use compressed air, electric batteries, pumps, or electric or hydraulic circuits with suitable switches, controls, etc.

Patent FR-2338578-A1 (FR)
IPC: H01J35/10
Filed: 1977-01-14
Abstract: X-ray tubes with a magnetic bearing either have the disadvantage that the anode must be at earth potential, so that an asymmetric high-voltage supply is required or that - in the case of a symmetric high voltage - a relatively wide air gap is necessary which requires a high driving force and a bearing which has a certain amount of drawbacks. The invention provides an insulator between the anode which is at the high-voltage potential and the rotor which is at the earth potential, so that the air-gap between the rotor and stator can be relatively small and an effective magnetic bearing is possible.

Title: Surface coating green clay mouldings - with sawdust to prevent damage by carrying supports
IPC: B28B11/16
Filed: 1977-02-24
Abstract: Earthenware articles are made by extruding a plastic clay compsn. through a moulding die to produce a slab which passes continuously onto a transporter and is cut into convenient lengths as it travels on the transporter. The blocks are then transferred to a dryer and the fired. Specifically a particulate coating is applied to the whole width of the lower surface of the continuous slab after it leaves the die, and the transporter is arranged to compress the particles against the plastic surface prior to reaching the cutter. The particles are pref. sawdust. Used in the mfr. of bricks, pipes, tiles and similar prods. The under surface, which is the one which is to become the exposed face, is not distorted or damaged when contacted with sawdust particles by the transporting support devices as it is without the sawdust coating. Hence an improved finish is obtd.
