Abstract: 1379362 Controlling vehicles EICHER TRAKTORENUND LANDMASCHINENWERKE GmbH Gebr 19 Jan 1973 [19 Jan 1972] 3021/73 Heading B7H [Also in Division F1] An arrangement for limiting the maximum speed of a vehicle includes a lockable lostmotion linkage connecting the accelerator pedal to an engine speed control device, e.g. the control lever of a fuel injection pump, the lost motion linkage being locked when low gears are engaged and being unlocked when high gears are engaged. In a first embodiment (Fig. 2 the accelerator pedal 115 is connected to the engine speed controller 117 by rods 114, 116 and a lost motion device 112 including a housing 123, locking member 119 controlled by electromagnet 118 and adjustable stop 122. When low gears are engaged by lever 129 switch 126 is closed, thus energizing electromagnet 118 so that the locking member 119 moves to a position in front of end face 120 of rod 114. Thus the lost motion device 112 is locked and the full range of engine speeds is permitted. When high gears are engaged by lever 129 switch 126 is opened and locking member 119 is retracted by spring 121. Depression of accelerator pedal 115 then causes no movement of rod 116 until rod 114 engages stop 122. Thus the range of engine speeds is limited, thus limiting the maximum speed of the vehicle. The maximum speed can be varied by adjusting the position of stop 122. In a second embodiment (Fig. 3) the accelerator pedal (not shown) is connected by lever 21 and linkage 17 to a lever 18 which carries a locking member 20, 22 operated by electromagnet 19. A rocking block 16 is mounted on the engine speed controller shaft 15. When low gears are engaged locking member 22 enters a recess 24 on the rocking block 16. When high gears are engaged the locking member 22 moves along a slot in the rocking block 16 until it engages an adjustable stop 25.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 3, 1930.] [Classes 83 (ii) and 83 (iv).] Uniting by fusion; angular bending and straightening ; rolling-mandrels and carriages and supports. -The longitudinal seams of circular or angular, plated or other metal tubes are continuously welded by a flame, which enters a jacket surrounding the tubes so as to bathe the inside and outside thereof and thus preheat the tube. A preheating flame of lower temperature may enter the jacket opposite the welding flame to cause the edges of the tube to converge in approaching the welding point. The tube is formed from metal strips by toll-bending and is passed from the final bending rolls 1 through sizing rolls 3 .. 6, between which it passes through guide rolls 10, 12 and a slot guide roll 11 and through a jacket 22, 23, Fig. 6, into which the flames from a welding burner 17 and preheating burner 19 project. The sizing rolls are of successively smaller diameter and are driven by successively smaller pinions so as to increase the peripheral speed in succession and thus to propel the tube forward. The tube then passes through straightening rolls 13 .. 16 and through a pair of ejecting rolls 18. A series of cylindrical or barrelshaped mandrels 7 are arranged in the pass of the sizing rolls and may be adjustably mounted on a screw rod, carried by a lug 9 projecting through the slot in the tube. The first mandrel is longitudinally grooved as shown in Fig. 3. The preheating jacket is formed in two longitudinally and transversely adjustable parts 22, 23, provided with tapered air holes 27 arranged at different heights and inclined towards the axis of the tube in the direction of travel. The flames of the burners project into the jacket through slots 25, 26. The spread of the flame from the burner 17 is restricted in the interior of the tube by the end of the first mandrel. The burner 17 is mounted in a support so as to be adjustable vertically, transversely and longitudinally, and is also pivoted and arranged to bear against a stop 21 in its operative position. Specification 264,534, [Class 83 (ii), Metal articles &c.], is referred to.
