Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1974-01-04
Abstract: 1486931 Fuel injection pumps CAV Ltd 20 Dec 1974 [4 Jan 1974] 00361/74 Heading F1A In fuel injection pumping apparatus having a cylindrical rotor 20, 21 rotatable in a body 12, 13 and including a transverse bore 43 in which reciprocate pumping plungers 44, the rotor has a large diameter portion 20 provided with inlet passages 53 for supplying fuel from a feed pump 24, 29, 30, 31 to the bore 43 and a small diameter portion 21 provided with a passage 47 for distributing fuel pumped from the bore 43 past a suck-back control valve 51 to a plurality of outlets 49 each controlled by a valve 50. The rotor is constructed of two parts 20, 21 coupled for simultaneous rotation by a pin 42. An enlarged portion 23 of the part 20 surrounds one end of the part 21 and is located between the base surface of the cup-shaped body part 12 and the part 13 plugging its open end. Each plunger 44 bears on a shoe 45 which is slidable in a radial slot in the enlarged portion 23 and carries a roller 46, the latter co-operating with an adjustable cam ring 27. The feed pump comprises a plurality of pistons 30 reciprocated in radial cylinders 29 by a stationary cam ring 24, the ring having an eccentric surface 25 engaged by bearing pads 31 on the ends of the pistons. Fuel enters the cylinders 29 through transfer ports 32 when they register with a kidney port 33 connected to a fuel inlet 35. During the inward strokes of the pistons 30, fuel is discharged through a kidney port 34 to a chamber 37 and thence to an annular gallery 36 and longitudinal grooves 54 in the periphery of the rotor part 20. The pressure established in the chamber 37 is controlled by a relief valve 38 which spills excess fuel to a return passage 40. The grooves 54 alternate with the radial inlet passages 53 whereby each time one of the grooves 54 registers with a port 58 or 59 one of the passages 53 registers with the other of the ports 59 or 58. The ports 58, 59 are connected to opposite ends of a bore 55 containing a shuttle 60 so that as fuel enters one end of the bore 55, fuel previously admitted to the opposite end is displaced by the shuttle 60, via the aligned passage 53, to a chamber 52 and thence past a non-return valve 62 in a sealed coupling 61 to the pumping bore 43. The stroke of the shuttle and thus the quantity of fuel admitted to the bore 43 is determined by plugs 56, 57 adjustable by a screw and an electric governor 61, respectively. Lubrication of the end faces of the enlargement 23 is effected by fuel passing thereto from the transfer ports 32 and through passages 41 connected to the bores 29.

The sheets are stripped from the slats by a stop plate 48 and transferred at a reduced speed on to a further conveyer 10 as an underlapping stream. The conveyer 10 may comprise co-operating belts 58 and 76 and may convey the sheets past a glue applicator roller 88 (for gumming the seal flaps of the envelopes). The treated sheets may be conveyed between belt 96 and pressure rollers 108 (with associated guides (14) into the nip between the belt 96 and a further belt 116. The sheets may be transferred to a more rapidly moving conveyer 126 to spread out the stream (to allow the gum to dry) before stacking.

Abstract: 804,583. Pipe couplings. K.A.C, Ltd. April 5, 1957 [Jan. 6, 1956 ; May 28, 1956], Nos. 584/56 and 16504/56. Class 99(1). An end fitting for helically corrugated metal tubing 3 comprises a plug 1 having external, helical convolutions dimensioned and formed for threaded engagement with the internal corrugations of the tubing, and a ring 5, provided with internal, helical convolutions dimensioned and formed for threaded engagement with the external corrugations of the tubing and adapted to be screwed over the end of the tubing, the plug and ring being sealingly secured on the tubing with the inner ends thereof substantially aligned by expanding the plug and/or by swaging the ring thereby to trap the tubing between the plug and ring. The terminal convolutions at the aligned ends of the plug and ring are relieved, e.g. by progressively removing the peaks of such convolutions over the final quarter or half turns thereof, to provide clearance between the tubing and those ends when the fitting is sealed on the tubing. The plug may initially be solid and be bored out after the fitting has been assembled on to the tubing, or the plug may be hollow and a mandrel inserted into the bore of the plug to support the latter during swaging of the ring. As shown, the tube 3 has a braided reinforcement 9 which is gripped between a sleeve 8 and the ring 5, the latter having external serrations 11 and an annular extension 7 closely fitting over a shoulder 4 of the plug ; the sleeve and the ring are swaged down simultaneously. In a modification, a sealing washer 14, Fig. 2, is disposed in an annular recess formed between shoulders 4 and 15 of the plug 1 and ring 5 respectively, and the ring is furnished with a groove 16 into which the reinforcement 9 is urged by a projection 17 on the sleeve ; the end of the latter extends beyond the extension 7 of the ring and is deformed to form an inward flange 18 and thereby trap the extremity of the reinforcement against the end face of the extension.

Filed: 1923-01-08
Abstract: 198,644. Montgomerie, J. C., and Stewart, W. June 2, 1922, [Convention date]. Rollers, treating; block, rubber, and like apparatus.-A copper roller g is rotatably supported in bearings a<2> carried by a bed a<1> and is polished by a stone c which is traversed to and fro along the roller and at the same time moved across the roller, whereby even wear of the stone is obtained. The carrier c<1> for the stone c is moved, during polishing along guides d which are adjustably carried by standards b. The movement of the carrier is produced by a screw h and a nut h<1> which engages the screw and has a vertical bar h<2> engaging slidably in the rear part of the carrier. Reversal of the direction of traverse is obtained by the alternate driving of a bevel-pinion k on the screw by two bevel-pinions carried by a driven shaft k<4> and clutched thereto by a clutch moved by the engagement of the nut h', at the ends of its stroke, with stops on a sliding rod operating a clutch lever; the screw also may be operated by a hand-wheel h<3>. The stone c is held in a chuck n, Fig. 4, having a stem n<1> mounted in a sleeve m<1> so as to be rotatable therein and movable axially under the action of a spring s. The sleeve is screwed externally and is slidable in a part c<2> by rotation of an internally-screwed worm-wheel m by means of a worm shaft t. On the part c<2> is rotatably mounted a flanged ring c<3> which rolls aJong the guides d as the tool is traversed therealong. The weight of the tool, the carrier, and the guides d is balanced by a weight f. The guides d are set, by means of arcuate slots d<2> in the standards b, so that at the commencement of a traverse, the bottom edge of the stone is in a horizontal plane containing the axis of the roller, and at the end of the traverse the top edge of the stone is in that plane. In a modification, the stone may have an oscillatory rotary movement imparted thereto by the engagement with grooves in the carrier of detachable ribs c<5> on the guides d.

A secondary cooling zone in a continuous casting apparatus comprises a shroud 15 within which the ingot is sprayed with a coolant, and in which a forced current of air flows continuously upwardly to one or more exhaust outlets adjacent its upper end. The air may be forced to flow by an exhaust fan &c. connected to the exhaust or by blowing air into the lower part of the shroud. The mould 10 is surrounded by an enclosure 11 which is maintained by compressed air from a source S, at a pressure greater than that in the shroud so that steam from the shroud is prevented from passing into the mould chamber and affecting equipment therein. Preferably the pressure in the chamber is greater than atmospheric so as to keep out smoke &c. produced above it by the casting equipment. The source S also supplies combustion air to the tundish heater. Air or steam jets may also be introduced at 30 to throw water off the surface of the ingot.
