Abstract: 1337817 Television DATA-PLEX SYSTEMS Inc 13 Aug 1971 [26 Aug 1970] 38177/71 Heading H4F A control box is provided between a standard television receiver and its aerial to blank certain of the signals received from the aerial while passing all the synchronizing signals to the television receiver. This is used for educational television where the television screen is split into four quadrants (or horizontal bands) and the viewer selects which quadrant he wishes to view by pressing a button on quadrant selector 32. This allows transmission of the signals relating to this quadrant through transmission gate 30 from the aerial to the receiver, the signals for the other three quadrants being cut off so that only one quarter of the television screen is used at one time. To ensure transmission of the synchronizing signals to the receiver inductive pick-up coils 18V, 18H are provided in a pick-up device which is attached to the back of the receiver, these coils sensing the vertical and horizontal synchronizing signals of the receiver, respectively. The resulting pulses from amplifiers 20V, 20H are delayed at 22V, 22H so that they correspond with the start of the next vertical and horizontal synchronizing signals respectively received from the aerial and trigger generators 24V, 24H which produce pulses of correct length to cover these synchronizing signals. These pulses are fed to transmission gate 30 to make this gate conducting regardless of the output of quadrant selector 32. The pulses from amplifiers 20V, 20H are also fed to quadrant selector 32 where each is fed to two monostable multivibrators (Fig. 5, not shown) of period half a field and half a line respectively, the output of each multivibrator being fed to two of four AND gates, the four AND gates each having an input controlled by a selection button on selector 32, so that an output signal is produced representative of the selected quadrant and is fed via an OR gate to transmission gate 30.

Abstract: 339,140. Kent, R. L., Morris Industries, Ltd., and Skinner, T. C. Dec. 24, 1929. Actuating by liquid pressure; single-acting bucket pumps.-In a fuel pump for internalcombustion engines, the piston i is actuated on the downstroke by a piston r which is moved by the oil circulated by the lubricating pump of the engine. The oil enters by the port w, and when the piston r is stopped by a ring v, the oil opens a valve s connected by a rod t to the piston i, thereby equalizing the pressures on the two sides of the piston r, so that the springs j, u may effect the upstroke to force the fuel above the piston i through the valve h to the engine. During the upstroke, fuel enters the chamber a through a pipe e, and during the downstroke it passes through a valve m in the piston i. The oil after passing through the valve s escapes by the port y while the port x is closed by the piston r. When the port x is opened by the upward movement of the piston r, the valve s and piston i can be moved up by the spring j.
