Title: System for transmitting graphical data using cartesian coordinates - modulates frequency of carrier to record on single tape track on sending end
IPC: B43K8/22
Filed: 1974-09-06
Abstract: System for transmitting graphical information. The information is picked up on the sending end side by a needle (1) traversing along a plane surface to produce signals that are indicative of the x - and y - coordinates of its position. These signals are used to modulate the frequency of a carrier. The modulated signals are recorded on a magnetic tape. The signals on the tape are demodulated at the receiving end to reproduce the displacements of the needle at the sending end. The modulated positional signals are recorded along a single track on the tape. The frequency deviation is chosen so small as to prevent overlap.

Title: Expanded plastic-filled cement insulation element - made by pouring mixt. in mould which sets in mould whilst held in vacuum for given time
IPC: B28B1/50
Filed: 1981-06-29
Abstract: Expanded plastic beads are mixed with an agent such as a bituminous prod. to bond it to cement, cement is added and a metered amt. of water whilst re-mixing. The mixt. is then poured into a mould (3) and removed for drying when set. After pouring into the mould, the mixt. is subjected to a vacuum for some time (e.g. 25-50 mbar for 5-7s).
