Title: Submarine vessel display system
Inventor: WRIGHT GRAHAM BOOTH
IPC: B63B49/00
Filed: 1982-05-18
Abstract: A display system for a submarine has a vector generator that supplies video signals to a cathode-ray tube (40) so as to produce a symbol (200) on its screen (42) representing the submarine. The orientation and location of the symbol on the screen is altered by the vector generator in accordance with the inputs from various sensors. The vector generator also produces a line symbol (110) on the screen representing the ordered depth of the vessel. This symbol (110) is moved towards the submarine symbol (200) as the vessel approaches its ordered depth, whilst the submarine symbol remains fixed. After the submarine has reached the ordered depth, subsequent change in actual depth causes the submarine symbol (200) to be displaced relative to the ordered depth symbol (110). The vector generator also produces digital numbers on the screen indicating various actual and ordered values, and causes these numbers to be displaced relative to one another as the values change relative to one another. <IMAGE>

Title: Data storage with error detection
Inventor: RATCLIFFE MICHAEL JOHN
IPC: G06F11/10
Filed: 1983-08-09
Abstract: Data storage apparatus consisting of an array of RAM chips 20, with Hamming code checking for detecting double-bit errors. Address signals such as Ao are fanned-out to the chips by way of driver circuits 31. Each driver circuit distributes an address bit to only two columns of chips (or in some case, just one column), so that if one of the driver circuits fails, no more than two chips in each row will be affected. Hence, no more than two bits in any data word will be in error, and this can be detected by the Hamming code. <IMAGE>

Title: LCD display devices
Inventor: TAKEDA MAKOTO
IPC: G09G3/36
Filed: 1984-09-07
Abstract: A matrix liquid crystal display device is provided with switching transistors made of amorphous silicon thin-film for example, which are connected to each display picture element, while the switching transistor uses the scan pulse width H which is set at a value greater than that is expressed by T/N, where H denotes the scan pulse width applied to row electrodes connected to each gate of the switching transistor, T denotes the total scan time and N the number of the scan lines. Concretely, the timewise width of the scan pulse is expanded or the number of applicable scan pulses is increased (e.g. by applying scan pulses from a preceding row). The preferred embodiments relate to such a liquid crystal display driving system that can effectively minimize the decline of the voltage and the display characteristics caused by insufficient charge against the display picture element electrodes via the switching transistors. In particular, the driving method embodied by the present invention is extremely useful for driving a large-capacity X-Y matrix liquid crystal colour display device. <IMAGE>

Title: Determining the head- retaining properties of beer and other beverages
Inventor: WILD PETER STANLEY
IPC: G01N21/59
Filed: 1985-07-15
Abstract: In providing a measure of the head-retaining properties of beer or other head-forming beverage, a sample of the beverage is dispensed so that a head is formed on it. Light is directed along a path traversing both the head and the liquid beneath the head. The light falls on a photosensitive device which yields an electrical signal depending on the intensity of the light. When liquid first becomes visible through a gap or gaps in the collapsing head, the value of the signal is noted and constitutes a standard for the beverage. When the head-retaining properties of a further sample of the beverage is to be measured, the sample is dispensed under standard conditions; for example a given volume may be run from a container into a glass with opaque sides. Light is directed through the head and liquid as before, and the duration of the period that elapses before the electrical signal takes the standard value is taken as a measure of the head-retaining properties of the sample. Apparatus has a window 8 above the photosensitive device, and a knob 10 for setting the standard value. A clock is started by a button 13 when the sample is dispensed, and when the detector output and standard value are equal the clock displays the duration of the period on an LCD 14. <IMAGE>

Filed: 1985-09-11
Abstract: A safety cut-off device for a machine uses a length of tubing (24) which is connected to a source of reduced pressure, such as a solenoid-operated piston and cylinder assembly (10, 19). A pressure-sensitive switch (16) is connected to the tubing (24). The switch (16) is held closed when the pressure in the tubing is low. The switch (16) opens if the pressure is increased by manual constriction of the tubing (24). The pressure sensitive-switch (16) and the source of reduced pressure (10, 19) are connected to opposite ends of the tubing (24) so that the switch (16) opens and fails safe if there is a blockage or leakage in the system. A second pressure sensitive switch (17) may be connected to the tubing (24) at the source of reduced pressure, such switch being arranged to open if either the pressure is increased by manual constriction of the tubing, or the pressure from the solenoid operated piston and cylinder assembly (10, 19) due to operation of a machine guard system which de-energises the electrical solenoid (10). A relay (11) may be de-energised to retain the machine into a stop mode. <IMAGE>
