The carrier member is mounted on a turntable 21 supported by rollers 23 on a base member 22. The turntable is rotatable by a motor and gear drive 26 which drives a pinion 25 engaging a gear 24 on the turntable to move the mould between positions 27, 31 and an intermediate position in which the ingate of the mould engages the outlet opening 7 of the nozzle. In operation, a mould is attached to the arm 13 in the position 27, the arm is lifted and is then swung to a position above the outlet opening 7. The hydraulic device is actuated to effect lowering of the arm so that the ingate of the mould engages the outlet opening. The stopper valve is raised so that the melt flows through the nozzle into the mould. The mould is retained in engagement with the nozzle until the solidifying front of the melt in the mould has entered the nozzle to form the plug 28, the stopper valve 5 being closed then or when filling of the mould is complete. The arm is then raised to disengage the mould from the nozzle and swung to the position 31 for opening the mould to release the cast product. A new mould may be mounted on the arm at position 31 or the arm moved to position 27 for mounting a new mould. A brush 32 may be moved across the outlet opening for cleaning the upper surface of the nozzle and the surrounding area. In another embodiment, the mould is engaged with the nozzle by raising the nozzle and, if desired, the total casting plant.

Title: System for recirculating exhaust gas from the exhaust passage into the induction passage of an internal combustion engine
IPC: F02M25/07
Filed: 1975-12-01
Abstract: 1522010 IC engine exhaust recirculation NISSAN MOTOR CO Ltd 1 Dec 1975 [30 Nov 1974] 49197/75 Heading F1B [Also in Divisions G2-3] A valve 30 permits recirculation of I.C. engine exhaust gases through a passage 18 in response to sudden opening of an induction passage throttle valve 14. In the embodiment shown the valve actuator chamber 38 is subject to a vacuum sufficient to move the diaphragm 36 against its spring-bias when a port 100 communicating with the atmosphere through an opening 102 is closed and the vacuum at an induction passage port 46 acts in the chamber. The port 100 is closed by the valve 110 when the vacuum difference in the chambers 64 and 66 is sufficient to overcome the spring 76 and the stem abutment 118 moves out of engagement with the portion 116 of the valve. A vacuum difference arises in the chambers 64 and 66 due to the flow restricting unit 71 when the vacuum downstream of the valve 14 falls in response to opening of the valve. The valve 92 in the unit 71 closes the passage 90 in response to the fall in vacuum in the chamber 84 and the rate of fall of vacuum in the chamber 66 is determined by the passage 88. The valve 92 may be formed by a leaf-spring. In further embodiments, Figs. 6 and 8 (not shown), the port (150, 166) controlled in response to the vacuum difference produced on opening valve 14 is opened by a valve (146, 174) connected directly to the diaphragm (141, 176) subject to the vacuum difference. The port (150) may be opened to communicate with the port 46 or with the engine intake manifold (185) (Fig. 8). The connection (154, 170) to the actuator chamber 38 has a permanently open connection (158, 178) to atmosphere. In another embodiment, Fig. 7 (not shown), the diaphragm (141) subject to the vacuum difference is coupled directly to the valve 30.

Title: Improvements in or relating to machines for applying insulating material around a coil for an electrical machine
IPC: H02K15/10
Filed: 1963-12-13
Abstract: 1,046,480. Covering cores with insulation. H. SCHUMANN Dec. 13, 1963 [Dec. 16, 1962; June 20, 1963], No. 49348/63. Heading B8G. A machine, Fig. 1, for ironing insulating material around the rectangularly - shaped straight arm 5 of coils for electrical apparatus comprises a pair of twoarmed levers 10 pivoted at 7 and 8 on a support ring 2a, each lever 10 having an ironing jaw 3, 4 on its inner arm and a gear segment 9 on its outer arm, one gear segment 9 meshing with teeth on a first drive ring 20 and the other gear segment 9 meshing with teeth on a second drive ring 20, the two drive rings 20 being axially spaced and meshing with common compensating gears 22 carried by a central drive ring 24. The ring 24 is rotated by drive means 26, 26a and the support ring 2a is braked by brake means 28 to 30. The brake means 28 to 30 creates a tendency for the support ring 2a to lay on the drive ring 24 and thus cause the two-armed levers 10 to press their ironing jaws 3, 4 against the coil arm 5. The compensating gears 22 permit the two support rings 2a to undergo any slight relative movement as may be necessary to cause the two ironing jaws 3, 4 to jointly engage the coil arm 5 whilst allowing for any eccentricities of the arm 5. Allowing for non-parallelism between, coil arm 5 and axis of machine.-In Fig. 4 the previously described support ring 2a is replaced by two axially spaced support rings 2a. Two arms 10 carry the iron 4 and are rigid with separate coaxial half-shafts 7a, 7b. Rotatable about the half-shafts 7a, 7b is an eccentrically mounted gear cage 34 carrying compensating gear 35 that mesh with gears 36 on the half-shafts. Rigid with the gear cage 34 is the gear segment 9 meshing with teeth on one of the two drive rings 20, the drive rings 20 being, as before, interconnected by compensating gears 22 carried by the drive ring 24. Upon movement of the drive ring 24 and braking of the support ring 2a, a torque is exerted upon the gear segment 9 and the gear cage 34 which is uniformly transmitted via the ends of the shafts 7a and 7b to the lever arms 10, thereby obtaining at both ends of the ironing jaw 4 the same engaging pressure against the coil arm 5. A similar arrangement exists for the ironing jaw 3. Automatically correcting pressure exerted by the irons.-As the irons 3, 4 are rotated about the body 5 the surface pressure exerted by the irons increases as the irons pass over the corners of the body 5 or over a small side thereof. To overcome this drawback a control element is moved in synchronism with the rotation of the irons, for example a disc 41, Fig. 5 (not shown), mounted on the output shaft of a gear train by the drive ring 24. The disc 41 is provided with control cams or formed with recesses so that a mechanical follower or optical scanner can be responsive to said cams or recesses to reduce the braking effect exerted by the braking device 28 to 31 as the iron passes over a corner of the body 5 or along a small side thereof.
