Title: Solid fuel combustion appliances
IPC: F24B9/04
Filed: 1980-12-05
Abstract: A solid fuel combustion appliance (1) has a grate (4) for supporting a firebed (60) which can be lit by an igniter (40). A hopper (20) is located over the grate (4) and beneath its outlet (20) is a fuel feed mechanism (24) in the form of an oscillatable plate (26). Air for the primary combustion zone 8 is introduced via inlet 30 and volatiles from the primary combustion zone (8) mix with secondary air supplied via passage 23 and apertures 21 for combustion in a secondary combustion chamber (44). Waterways 52 within the appliance define passages communicating with the exhaust outlet 54. The level of the firebed (60) may be detected by a sensor which serves to regulate the operation of the fuel feed mechanism (24) to feed fuel onto the firebed (60) incrementally. <IMAGE>

Title: Altering feeding intervals during banknote sorting
Inventor: DIXON CHRISTOPHER JOHN
IPC: B65H7/06
Filed: 1982-09-20
Abstract: During the verification and sorting of banknotes etc, it is important that the banknotes reach detectors (3) at or close to predetermined intervals, which may be defined by clock pulses. In this invention, the detector (3) senses the interval between the arrival of a banknote at a given point on the path (2) and a corresponding clock pulse. If this interval is too long, the banknote is passed around a looped path (15) at the end of which the banknote re-enters the first path (2) and is represented to the detector (3). The time of travel of the banknote in the loop path (15) is such that the timing error is reduced. The recirculation of the banknote may be repeated. Preferably, two loop paths (15, 17) are provided for advancing or retarding the timing of a banknote in relation to the clock pulses. A buffer loop which does not alter the timing of the banknotes and a skew-removing loop having two belts (18a, 18b) of different lengths are also provided. Banknotes which are correctly timed and which are not required to recirculate in the buffer loop and which are acceptable to detector (3) are taken out of the first path (2) by a peeler wheel (4). Unacceptable notes are removed by stacker wheels (5, 6) and doubled notes are fed to pockets (13). <IMAGE>

Patent GB-2149256-A (GB)
Title: Phase measurement
Inventor: JEKEL RICHARD N
IPC: G01S13/84
Filed: 1984-08-07
Abstract: The system includes a transmitter 11, a receiver 30, and a coupling network 14 which connects the transmitter 11 and receiver 30 to the antenna 20. The network includes a switch 34 which selectively enables the receiver 30 to receive signals either from the transmitter 11 directly or from the antenna 20. A phase measurement device 32 determines the relative phases of the signals received by the receiver 30. Another switch 38 is provided to ground the connection 12 between the transmitter 11 and the network 14 when the receiver 30 receives a signal from the antenna 20, thereby removing the transmitter 11 impedance and making the phase shift of the connections from the transmitter 11 to the antenna 20 substantially equal to the phase shift from the antenna 20 to the receiver 30. A detection loop 52 close to the antenna 20 is connected via the coupling network 14 to the receiver 30 to allow the phase delay through the antenna coupling hardware to be calculated. The difference between the phase of a transmitted signal measured at the transmitter 11 and one measured at the detection loop 52 near the antenna 20 represents the total phase delay of the antenna hardware. This delay can be removed from the calculated phase difference to reflect the true phase delay at the antenna 20. <IMAGE>
