Title: Apparatus for displaying waveforms on a television receiver
IPC: G09G1/16
Filed: 1979-07-23
Abstract: A vertical waveform is generated on a television receiver in response to, for example, an audio signal by pulses from a monostable 17 which is triggered by line sync pulses from a generator 10 and which resets when a capacitor 20 has charged sufficiently through a transistor 22. The monostable 17 resets to a variable datum level which is determined by a catching diode 23 in accordance with the modulating signal applied to a terminal 28. The modulating signal thereby shifts the location along the line scan of the point of reset. The pulses can be used to modulate luminance and/or colour on a TV receiver. A second monostable 15 generates short pulses for drawing a band on the screen. Two circuits can be used with simple logic to form three coloured patterns on the screen. <IMAGE>

Title: Improvements In or Relating to Terminal Systems for Data Processors
IPC: G09G1/16
Filed: 1979-12-13
Abstract: For a CRT display system incorporated into a data processing system in which all units are coupled to a system bus, a method of dividing the bus system timing into alternate CPU cycles and Direct Memory Access (DMA) cycles whereby the peripheral devices operating in a DMA mode have direct access to memory without degrading the CPU performance. The duration of each cycle is typically 508.5 nanoseconds. The bus timing is also split into an address phase and a data phase which are offset from each other typically by 305 nanoseconds. The timing signals are generated by clocking a number of serially connected shift registers and using outputs from individual stages thereof to set and reset a number of storage devices. The outputs of the storage devices act as gating signals respectively for assigning cycles of the bus alternately to the peripheral devices for direct access to the memory and the CPU for other system operations.

Title: Drum speed control system for a washing machine
Inventor: SETH SIYA VALLABH
IPC: D06F37/20
Filed: 1981-07-31
Abstract: The drum speed is controlled to pass for a period through an intermediate speed, during which articles of the laundry load distribute themselves evenly around the drum, before the drum speed is increased to a spin-dry speed. During the period of intermediate speed any load imbalance causes the speed to change cyclically instead of remaining constant. If such a change is detected, the drum is caused to slow down and pass through the intermediate speed again in order to redistribute the laundry load in the drum.
