Title: Apparatus for detecting and monitoring fluid flow
Inventor: HAINES GERALD JOHN
IPC: G05D7/06
Filed: 1996-03-18
Abstract: In order to accurately monitor the start of a fluid flow from header tank 1 via one way valves 6, 14, in a system of pipes 7-12, and especially in conditions of low head pressure, one or more pressure transducers T 3, 4, 5 are used to monitor the static head pressure drop due to the acceleration of the fluid. This momentary pressure drop can be used to start a pump 2, which increases the pressure in the system. The pressure transducers can be used to monitor the pressures of and pressure differences between the tank and the fluid outlets 7-12 in order to 1) maintain a certain pressure and 2) to stop the pump if there is no fluid flow. In a system comprising one pressure transducer, after the said pump is running, the pressure transducer can be used to monitor the pressure in a closed system and, if the pressure does not fall after a deliberate reduction of pump speed, this information can be used to stop the pump.

Title: Method and circuit for generating internal pulse signals in a synchronous memory
Inventor: OH JONG HOON
IPC: G11C11/407
Filed: 1997-05-02
Abstract: In a method and a circuit for generating internal pulse signals in a synchronous memory first pulse signal is generated at 104 in response to a burst mode command to transfer an external column address to an internal column address line. After the generation of the first pulse signal, a second pulse signal is generated at 106 to transfer an internal column address from an internal column address counter to the internal column address line in each clock cycle until the burst mode operation is advanced by a predetermined burst length. When a burst interrupt is generated in burst mode operation to perform the burst mode operation in response to a new external column address, the first pulse signal is generated and the generation of the second pulse signal is suppressed. Alternative embodiments are described (Figs 4 and 6). A circuit (Fig 8) of each of external input buffers 103 is described.

Title: Method for driving a liquid crystal display
Inventor: KIMURA YASUHIRO
IPC: G09G3/20
Filed: 1997-05-14
Abstract: In a colour liquid crystal display grey scale data for one colour is fed to a computing circuit 32. This circuit modifies the grey scale data by addition or subtraction so that it has the same transmissivity as the other colours. The unmodified greyscale signals for the other colours are directed to a buffer 26 which delays the signals while the modified greyscale is being generated. This technique corrects for the dependency of the transmissivity/voltage characteristic on wavelength.

Title: Spray nozzle assembly for a dishwasher
Inventor: CHUNG UI-SHIK
IPC: A47L15/23
Filed: 1997-12-11
Abstract: A spray nozzle assembly for a dishwasher is constructed so that there are variations in the direction of the spray jets as the spray arm rotates. In the example the arm 310 is rotatably mounted in the dishwasher and comprises a hollow body for receiving water via an adaptor 180 connected to the water outlet 144 of the pump. The arm has a series of jet nozzles 312 for spraying water. Some nozzles 320 have eg spherical heads so that they can pivot in the arm. The lower part 326 of these nozzles is connected to a spring 332 mounted inside the arm. One end 330 of the spring is connected to an eccentrically mounted member 350 and the other end is fixedly connected to the outer end of the arm. As the arm rotates the eccentricity causes the spring to expand and contract, and as the nozzles 320 are connected to it, they pivot back and forth in their mountings in the arm and thus the direction of their jets varies cyclically. This ensures better coverage inside the dishwasher and reduces waste of the washing liquid.
