Title: Multi-leaf collimator
Inventor: TOPOLNJAK RAJKO
IPC: G21K1/02
Filed: 2003-07-08
Granted: 2006-03-01
Abstract: A multi-leaf collimator is disclosed which alleviates the problems of inter-leaf leakage and pixellation. The collimator comprises a first multi-leaf collimator set, a second multi-leaf collimator set at an acute angle to the first, and a third multi-leaf collimator set at an acute angle to the second. Each multi-leaf collimator set will usually include a pair of leaf banks mutually opposed to each other. The acute angle between the first and the second multi-leaf collimator set is preferably the same as the acute angle between the second and the third set. A suitable angle is about 60°. To improve the penumbra characteristics, (i) the leaves of the multi-leaf collimator closest to the radiation source can be deeper in the direction of the radiation than the leaves of a multi-leaf collimator more distant from the radiation source, (ii) the leaves of the multi-leaf collimator furthest from the radiation source can be shallower in the direction of the radiation than the leaves of a multi-leaf collimator closer to the radiation source, (iii) the tips of the leaves of the multi-leaf collimators can be rounded (iv) the radius of curvature of the tips of the leaves of the multi-leaf collimator closest to the radiation source can be greater than the radius of curvature of the tips of the leaves of a multi-leaf collimator more distant from the radiation source, and (v) the radius of curvature of the tips of the leaves of the multi-leaf collimator furthest from the radiation source can be less than the radius of curvature of the tips of the leaves of a multi-leaf collimator closer to the radiation source. In general, it is also preferred that the first multi-leaf collimator is closest to the radiation source, the third multi-leaf collimator is furthest from the radiation source, and the second multi-leaf collimator is between the first and third multi-leaf collimators.

Title: Cleaning appliance
Inventor: WHITE WILLIAM ROBERT JAMES
IPC: A47L9/24
Filed: 2004-05-13
Granted: 2007-06-27
Abstract: A cleaning appliance has a main body and a hose attached thereto, the hose being attached to the main body by means of a connector. The connector is movable between a first position in which the hose is stored on the main body and a second position in which the hose provides a dirty airflow to the main body for cleaning purposes. When the connector is in the second position, the hose extends away from the main body in a plane which passes through the centre of the main body. This improves the balance of the main body during use.

Title: Improvements in or relating to a safety-belt tongue and a safety-belt arrangement
Inventor: MAGNUSSON THOMAS
IPC: A44B11/06
Filed: 2004-05-25
Granted: 2007-12-12
Abstract: A safety-belt tongue defines a throat (26) through which a safety-belt (3) may pass. The throat (26) is associated with a clamping element (28), the clamping element (28) initially being retained in a release position and being moveable to a clamping position, in response to a force or tension in part of the safety-belt. In the clamping position, the clamping element (28) engages the safety-belt (3) and clamps the safety-belt (3) against part of the throat (26) to prevent movement of the safety-belt (3) through the throat (26). The tongue may be configured to be engaged with a buckle. The clamping element 28 is initially held in position preferably by frangible trunions which extend from opposed ends of the clamping element 28 and engage within bores 29 provided for that purpose in recesses 27.

Title: Storing and reproducing analogue signals
IPC: G10L13/06
Filed: 1980-12-15
Granted: 1984-02-29
Abstract: An analogue signal, such as a speech signal, is encoded by a delta modulation encoder 3 and stored in a digital memory 5, or is decoded by a delta modulation decoder from the store 5. The speed at which the bits are produced by an encoder 3 and read into the memory 5 or read out of the store 5 and decoded by the decoder is controlled by the instantaneous value of a characteristic quantity of the analogue signal or the associated binary coded signal. The characteristic quantity may be the binary pattern which is produced by a limited number of successive bits of the encoded or read-out signal. It is thus possible to reduce the memory space required for a given length of signal to be reproduced with a given quality. <IMAGE>

Title: Improvements in or relating to radio communication
Inventor: HILLUM RICHARD ARTHUR
IPC: H04B1/68
Filed: 1991-03-14
Granted: 1994-09-28
Abstract: In a tone-in-band (TIB) single-sideband-modulated communication system used to communicate digital data:-   a) In order to compensate for variations due, eg, to doppler shift of the pilot tone in the received signal, during the sweep of the frequency of a local oscillator used to tune the receiver, the output of a narrow band filter is monitored for the presence of the expected pilot tone. When the pilot tone appears to be present, the sweep is interrupted and the error rate of the demodulated digital signal is tested, the sweep being resumed if an excessive error rate is encountered. b) In order to counter misreception due to co-channel interference, the pilot tone is offset by a small but detectable amount from that used in a co-channel transmission in preparing the TIB transmission either by using a different frequency split-point or by producing the signal in a slightly different part of the channel.   <IMAGE>

Title: Viscose filament spinning process - uses a simplified drying phase and carbon disulphide extraction to shorten process
IPC: D01F/
Filed: 1974-10-17
Granted: 1979-04-10
Abstract: A process is claimed for the manufacture of viscose filaments, where the viscose solution is continuously passed through a spinarette followed by final reduction and washing and brightening and drying, the filaments being cooled during the final reduction phase to a temp. below the evapn. point of the carbon disulphide, the cooled filaments being then washed and brightened. In the drying phase the temp. is controlled to give a simultaneous extn. of the residual moisture and the carbon disulphide from the filaments. The simplification of the drying phase and the extn. of the carbon disulphide shortens the filament manufacturing process and removes one manufacturing stage from conventional processes.
