[Also in Divisions F1 and H1] A fuel injection system for an internal combustion engine uses a magnetic switch device 24 in which magnetic reed contact units are operated by a magnet in timed relation to the rotation of an engine shaft and are connected to provide input signals for pulse generators 20 and 21, each of which produces energizing pulses for a group of electromagnetically operated fuel injection valves 22 which are thus opened for a period depending on the duration of the pulses. Each of the pulse generators is fed with two variable voltages V1, V2. The voltage V1 varies as a function of manifold pressure and engine speed and the voltage V2 varies as a function of engine water temperature, air temperature and acceleration. The switch 24 may also provide a signal to a discriminator 25 which provides the engine speed signal.

Abstract: 1422348 Mowing machines C VAN DER LELY NV 27 Dec 1972 [27 Dec 1971] 59688/72 Heading A1F [Also in Division El] In a sweeping or mowing machine having a receptacle 6 for sweepings and/or mowings from rotary vertical-axis brush or mowing elements 9 the sweepings &c are positively pushed into the receptacle 6 by means such as an oscillating piston 59. In the self-propelled machine shown a horizontal brush cylinder 28 behind two laterally-spaced vertical-axis brushes 9 lifts sweepings into arcuate rearwardly-tapering channels defined by ribs 24. From the mouth 26 of the channels the sweepings fall into the path of a piston 59 which comprises a rectangular bar extending across the machine and is oscillated by external arms 60 pivoted at 61 and linked to an eccentric drive 62. The sweepings are thus pushed past a pivotal flap 52 into the receptacle 6 and retained by barbs 54 as the piston withdraws. The receptacle 6, which has a mesh or other air-permeable panel 57, is suspended by arms 43 from a shaft 38 actuated by a hand-driven worm 40, whereby it can be raised for discharge of the sweepings through a spring- loaded flap 46 opened automatically by a cable 70. The brushes 9 are driven by contra-rotating telescopic universally-jointed shafts 17 and are removably mounted in a rearwardly-open housing 13-19-22 which is pivotally mounted on a horizontal shaft 21 and is adjusted for brush height and pressure by a hand lever 33. The machine incorporates fixed side plates 23 preferably engaged by bristle or sealing strips on the housing edges. An engine or electric motor 8 has a variable speed control 72B, a horizontal output shaft 63 for the rear wheel, rear brush, and piston drives, and two vertical output shafts for the brushes 9. The brushes 9 may be replaced by mowing elements, Fig. 4 (not shown), comprising blades (72) and optionally brush portions (72A). In a modification, Figs. 5-8 (not shown), dispensing with the barbs 54 and pivotal flap 52, the inlet to the receptacle (6) is closed by a pair of bevel-edged slide flaps (73, 74) which are pulled together by a spring (81) and are opened at each forward movement of the piston (59) by camming elements (85, 86) carried by the arm (60).

Abstract: 1,205,170. Lining tubes. AJINOMOTO CO. Inc. 18 Dec., 1968, No. 60233/68. Heading F2P. In apparatus for expanding a flexible, e.g. rubber, lining 8 or 23 into bonding relationship with the inner surface of an arcuate or straight tube, 7, or 24, respectively, which surface has previously been coated with adhesive, a stopper comprising a flexible washer or washers 9 or 22 is caused to travel through the lining by fluid pressure, e.g. compressed air or superheated steam (to cause simultaneous vulcanization), and means is provided for restraining the relative movement between the stopper and the tube so as to limit the speed of such movement and prevent the stopper from being ejected out of the end of the tube remote from that at which it is first inserted. In the embodiment of Fig. 2, the tube 7 is clamped concentrically to a rotary table (1, Fig. 1, not shown), and the stopper is secured by a nut to one end of a substantially rigid pipe 3 which passes through the lining and tube in an arc of the same radius as that of the tube and is clamped beyond the remote end of the tube to the table. The portion of the lining adjacent the end of the tube where the stopper was inserted, having been bonded to the tube manually prior to insertion of the stopper, is now sealed with a plate 11 and bolts 10, and air or steam are passed into the space between the stopper and plate 11 to cause movement of the tube relative to the stopper, allowed by the rotary table, whose rotational speed may be controlled manually, to bond the remainder of the lining to the tube. In the embodiment of Fig. 3, the tube 24 is fixed to a stationary support, a cable 29 is secured at one end to the stopper, which has two flexible washers 22, a plate 32, carrying an inlet 31 for air or steam and a sealed aperture 30 for the cable 29, is secured by bolts 33 to the end of the tube at which the stopper has been inserted, the other end of the cable is wound around a drum which is braked to a predetermined extent, and the air or steam is supplied to the inlet 31, whereby the stopper is moved through the tube at a speed determined by the amount of braking applied to the drum and stops moving when the cable is fully paid out, which is arranged to be when the plunger has reached the other end of the tube.
