Title: Recording and playback
IPC: G11B7/12
Filed: 1978-11-02
Abstract: This invention relates to the writing on and reading from, a video disc record of frequency modulated video information signals, for example, for a television record. The video information is formed into a frequency modulated signal which is used to vary the intensity of a laser writing beam which forms a track on the metallised surface of a video disc, consisting of non- reflective lengths of the track, corresponding to marks of the frequency modulated waveform, and reflective lengths of the track corresponding to the spaces of the frequency modulated waveform. The track can be read by use of a reading light beam and collecting light reflected from the reflective lengths as the beam moves over the track. There are feedback means for maintaining the average intensity of the writing light beam, and means for monitoring the record after it has been formed by comparing it with the original waveform to be recorded.

Title: Device for Sorting Sweets
IPC: B07B13/05
Filed: 1979-02-19
Abstract: Sweets to be sorted are conveyed one behind the other along longitudinal troughs 5a, Fig. 4, formed in rib portions 5b of a vibratory separation conveyor 5, Fig. 1. The cross-section of each rib is narrowed along a downstream portion of the conveyor so as to define a sorting gap 5d, Fig. 5, between adjacent ribs. A guide 6 extending longitudinally of each trough is adjustably arranged at a distance x, corresponding to the thickness of an accurately sized sweet, from an oblique bottom surface of the trough, and at a horizontal distance y, from the edge of that oblique surface, which is slightly smaller than the distance of the centre of gravity of an accurately sized sweet from the guide 6. When the sweets being conveyed reach the gaps 5d, accurately sized sweets, due to the position of their centre of gravity, topple over and drop through the gaps into a chute 7. Undersize sweets remain the troughs and are delivered by the conveyor to a removal shaft 8 together with oversize sweets which cannot fall through the gaps 5d. <IMAGE>

Title: Time switch for digital exchanges
IPC: H04Q11/04
Filed: 1979-06-19
Abstract: A time switch for use in digital telephone exchanges is constructed on a bit slicing principle and comprises one bit slice for each bit of a companded digital signal and one spare. Each bit slice comprises a memory and a slice controller. A configuration control element which comprises a micro-computer is coupled to each bit slice. An input digital signal is converted to parallel form and allocated to its respective bit slice in accordance with bit slice addresses provided by the configuration control element. In response to an address signal provided by the slice controller, the digital signal is read out. If one of the bit slices develops a fault, its address is reassigned to the spare bit slice. However should a second or subsequent fault develop, then the configuration control element reassigns the addresses of the serviceable hit slices so that the bits of higher significance are still handled by the time switch.
