Title: Stabilization of EHT voltage and horizontal scan for magnetic deflection        cathode ray tube circuits
Inventor: HOLMES STUART JACKSON
IPC: H04N3/185
Filed: 1993-07-12
Abstract: The raster geometry of a cathode ray tube display is stabilized against variations caused by beam current loading. This is done by regulating the B+ voltage supply to the horizontal deflection circuit, which generates EHT, and controlling the regulator according to the magnitude of the EHT. Therefore beam current loading which depresses the EHT will no longer affect the raster geometry. This arrangement is particularly suited for use with 16:9 wide aspect ratio television receivers. <IMAGE>

Title: Optical transmitters
Inventor: DALEY ROBERT
IPC: H04B10/155
Filed: 1993-08-04
Abstract: An optical transmitter for a TPON (telecommunications over passive optical network) has a servo circuit 31, 32, 34, 36, 42, 44 controlling the optical output power of a laser 38. To bring the output power to a demand level when the transmitter is first connected to the network, the servo circuit causes the source 38 to produce a series of optical pulses and monitors their power using an optical sensor 40. If the monitored power level of a pulse is less than the demand level then the drive signal ID applied to the source is increased, whereas if the monitored power level is greater than the demand level, the drive signal is decreased. The drive signal for the first pulse is half the maximum drive signal, and the predetermined adjustment amount is initially one-quarter of the full scale drive signal value and is thereafter halved for each successive pulse. In such a transmitter the power selling operation is desirably fast and accurate. <IMAGE>

Title: Thermostatic mixing valve
Inventor: SAUR ROLAND
IPC: G05D23/13
Filed: 1994-07-08
Abstract: In a cooling system of an i.c engine, a thermostatic mixing valve has stationary housing 13 sealed by membrane 15 and containing material which expands with increasing temperature to project piston 17 carrying pot-shaped disc valve 18, 23, 26 and by-pass disc valve 27, which valves bound mixing chamber 30. At engine start, as shown, water from the engine is passed from by-pass pipe 32 to engine feed pipe 33 via valve 27. As the water heats, piston 17 is projected to open valve 18, to pass cooled water from a radiator pipe 31 to the chamber 30, and close valve 27. The thermostatic valve thus controls the temperature of water passed to the engine, its housing 13 and the expandible material therein being subject to the temperature of cooled radiator water via slots 35 and heated by-pass water via slots 22 in the pot-shaped disk valve. <IMAGE>

Patent GB-2287168-A (GB)
Title: Dispensing or spreading apparatus
Inventor: MCCREDIE PAUL JOHN
IPC: A01C3/06
Filed: 1995-02-22
Abstract: A material dispenser, eg. a manure spreader, has a hopper (2) provided with a horizontal-axis auger (4) feeding a distributing impeller. The hopper walls are downwardly convergent and on the descending side of the auger in its direction of rotation, are closest to the auger in a region near to a horizontal diameter of the auger. The wall (20) slopes upwardly at about 40 DEG  to the horizontal away from that region of closest approach. Thereby less power is needed to drive the auger when dealing with material which is prone to clumping. In another aspect, at the rear end of the auger in the direction of feed, adjacent to the hopper rear end wall, there is a shielding portion (24) arranged to prevent the wrapping of elongate fibrous elements around the auger rear end. For this purpose the shielding portion may be an end segment of an auger flight with a peripheral edge increasing in radius progressively towards the main length of the flight. <IMAGE>

Abstract: The invention relates to a machine for use in connection with the lifting up of seed potatoes and the like tuber or root crops and to a corresponding method. The machine comprises a number of lifting shares (3) and at least one endless conveyor chain (4, 5) to be rotated by the driving means of the machine, for the clearing or lifting up of the potatoes (2), and a covering tool, especially covering discs for the subsequent covering up of the potatoes. Alternative embodiments of the machine further comprise a plough share (6) ploughing a groove, into which the potatoes are put down, and preferably additionally a down chute (8) for the potatoes. The machine preferably clears two rows of potatoes, putting them down into one central row. The machine is used to avoid the transmission via green flies of harmful virus to the seed potatoes, and in order to obtain suitably matured potatoes having a firm skin. Using the machine an environmental advantage is also obtained, since there is no need for the tops of the potato plants to be withered down using chemical sprays, and besides the whole sequence of operations of the process is streamlined. Finally, the tendency of black scurf is reduced. <IMAGE>
