Title: I.c. engine fuel injector
Inventor: STRINGFELLOW CHRISTOPHER
IPC: F02M45/08
Filed: 1993-09-17
Abstract: A valve member 20 is lifted from a seating 16 by fuel under pressure to provide fuel flow through an outlet 17.

Title: Digital gate generation for signal measurement apparatus
Inventor: TAMBE ATUL
IPC: G01R23/10
Filed: 1993-10-21
Abstract: In a method of digitally controlling a gate for a timing counter (219, fig 1 not shown) to open and close in response to the occurrence of signal events, a digital divider (305, 307, 309) controls the gate, so that, when a pulse burst of IF signal is encountered (308) the gate opens on the second signal event The divider can be programmed (301) to close (318) the gate any integral number of signal events later. Measurements are taken while counting time events from a precision clock. A series of measurements can be taken with various integral numbers of signal events for frequency profiling. By incrementing the digital divider from n to n+1 signal events for successive measurements, and subtracting the results, very narrow gates are effectively generated which move through the pulse cycle by cycle for frequency profiling. <IMAGE>
