Title: Exhaust gas recirculation control system for an internal combustion engine
IPC: F02M25/07
Filed: 1975-06-18
Abstract: 1504368 Exhaust gas recirculation control in IC engines NISSAN MOTOR CO Ltd 18 June 1975 [24 June 1974] 25919/75 Heading F1B An exhaust gas recirculation system for an IC engine has, in the recirculation duct 16, between the exhaust system and the inlet manifold 22, a flow control valve 10 operated by vacuum supplied from a source (not shown) via duct 34. The degree of opening of the valve 10 is primarily determined by the depression at a carburetter Venturi 30 sensed by a duct 28, which depression is amplified by a vacuum amplifier 32. However the depression from the carburetter Venturi is modified to maintain the quantity of recirculated exhaust gas constant, since the quantity of gas recirculated is proportional to the pressure drop over valve 10 as well as its degree of opening, by sensing the manifold depression via duct 70 and bleeding air into the Venturi vacuum by opening a valve 62. The air may be bled either into a chamber of the vacuum amplifier or into the Venturi vacuum conduit (not shown).

Abstract: 463,322. Glass manufacture. PEARSON, T. F. Sept. 23, 1935, Nos. 26248 /35, 33682 /35, and 12476/36. [Class 56] Relates to a device for connecting one or more parts of a glassworking machine to the driving-mechanism in predetermined relative positions, the drive being taken up at starting without shock. According to the invention, the driving and driven members are provided with complementary projections and recesses of varying depth longitudinally and of transverse taper, and with positive interengaging abutments at their ends. In the construction shown, a member 10, which forms part of a table carrying mould units, is rotated by a ring 11 that is driven by a worm 12. Driving connection between the parts 10, 11 is effected by a clutch pin 15 which slides through a sleeve 14 secured to the member 10 and has a shoe 16 that engages one of a number of grooves 20 formed in the ring 11. The shoe 16 has tapering sides 17 and is also inclined longitudinally at 18 and 19. Each groove 20 increases in depth from the entering end 21 to the rear end which is formed with an inclined abutment 22, and the sides are also inclined to one another, as shown in Fig. 1. Thus at starting, as the shoe 16 enters the groove at 21, it engages the sides of the groove over an increasing area of its tapered sides 17 and takes up the drive gradually until it makes contact with the abutment 22. The shoe is forced resiliently into the groove by a spring 24 which surrounds the pin 15. A lever 29 enables the shoe to be lifted out of the groove when the parts 10, 11 are to be disconnected. In the event of an overload occurring, the inclined front edge 19 of the shoe will ride over the inclined abutment 22. In a modified construction, a second spring is provided to increase the resilient load on the shoe 16 when starting the drive. In another construction, the grooves 20 are replaced by projections on the ring 11 which are tapered longitudinally and transversely, and the lower end of the pin 16 is saddle-shaped to engage the projections.
