Title: Method and apparatus for reproducing operating conditions in induced flow devices
IPC: G01F9/00
Filed: 1975-04-28
Abstract: 1510371 Automatic control of testing carburetters SCANS ASSOCIATES Inc 28 April 1975 [25 June 1974] 17540/75 Heading G3N A carburetter testing arrangement includes a control system for the motor which positions the throttle (butterfly) valve so that a desired vacuum is obtained with a predetermined air-flow. The valve is driven by a stepping motor whose speed is reduced as the final position is reached by providing the arrangement shown where device 73 measures the pressure, or vacuum, produced by the carburetter which is controllable by movement of the throttle valve. The device 73 may be a single, variable area Venturi meter or multiple fixed area meters operating on either sonic flows and providing an absolute pressure signal. This pressure or vacuum signal is compared with a desired test point signal from computer 75 both to determine which signal is greater in comparator 76 and the value of this difference using comparator 80. The former comparison is used to set the direction of rotation of stepping motor 42 and the latter comparison provides, by means of converter 81, a pulse signal whose frequency corresponds to the value of the difference and this is used in translator 79 to control the speed of motor 42. The test points typically are idle, near idle, part throttle and full throttle and to obtain fine control of the movement of the throttle valve near idling the drive from motor 42 includes elliptical gears, (see also Specification 1510372). In a manual setting condition a potentiometer may replace the computer to provide the reference signal. The physical layout of the apparatus is described and shows the test console used and the method of attaching the carburetter, Figs. 1 and 2 (not shown). The carburetter may also be tested using subsonic air-flow where the basic vacuum is set at idling condition and the air-flow quantity altered and monitored is described and claimed in Specification 1510373.

Title: Improvements in time and distance registering apparatus for use on vehicles
Filed: 1923-07-09
Abstract: 222,589. Bath, C. M. H. July 9, 1923. Registering duration of speeds defined by limiting values.- The running time of a vehicle is registered upon trip and total counters driven from the vehicle under the dual control of a clockwork and a speed sensitive element. The time counters are actuated by an arm P<2> mounted upon a spindle P<3> adapted to be rotated by the vehicle through a worm B, worm wheel D and a friction coupling D'. The rotation of the spindle is under the control of an escapement P oscillated by a cam X<2> rotated from a shaft L. When the speed sensitive mechanism is in motion, the shaft L is slid endwise bv means of a lever K so as to have driving connection at M with the minute wheel of the clockwork. Consequently the shaft makes one rotation per minute and allows movement at the same rate to spindle P<3> and the arm P<2>. A drum O graduated in seconds is mounted at the end of shaft L and may be zeroized by means of the button S<1> and gearing S, R. The clockwork or its spring may be energized by the vehicle through the worm B, worm wheel C and friction coupling C<1>. There may be combined in the one instrument in addition to the time counters, a time-piece, speed indicator and trip and total odometers. The clockwork may be fitted with the overwinding-preventing means described in Specification 222,773, [Class 139, Watches &c.].
