Title: Fuel injection pump assembly
IPC: F02M59/42
Filed: 1975-03-17
Abstract: 1499126 Controlling I C engine fuel injection pumps HOLEC NV 17 March 1975[22 March 1974] 11082/75 Headings F1A and FIB In a fuel injection pump in which each pumping piston 63 is reciprocated by an armature oscillated by the timed energization of an associated electromagnet L 1 , Fig. 6, during the starting of an associated engine a pulse generator 34 controlling the energizations is arranged to double the normal number of energizations. Thus excess fuel is supplied during engine starting. The pulse generator 34 comprises coils 16a..16d, 102a .. 102d mounted on a support 100 and an engine driven permanent magnet 15 for causing sequential energization of the coils as it rotates therepast. Each of the coils 16a..16d supplies pulses to an individual monostable multi-vibrator circuit 17 (only one shown) for energizing its associated electromagnet L 1 ... During starting a knob 104 is depressed to close contacts 81 and thereby energize a starter motor 96. Simultaneously contacts 103a .. 103d are closed thereby connecting each of the coils 102a..102b to one of the circuits 17. Accordingly each circuit receives an additional pulse from whichever of the coils 16a-16d is connected thereto, whereby the electromagnet L 1  in circuit therewith is energized twice as frequently during starting. A speed, torque and/or temperature-sensitive regulator 99 is arranged to shift the support 100 and thus effect a change in the timing of the pulses. The pump construction, Fig. 2, is identical to that described in Specification 1499124, wherein wedges 26, 33 are movable longitudinally to alter the strokes of the pumping pistons 63. A piston 80 responsive to changes in engine manifold pressure and a device 77 responsive to changes in atmospheric pressure are used to move the wedges.

Title: Method for producing phosphates
IPC: C01B25/42
Filed: 1964-03-17
Abstract: A crystalline condensed phosphate which is a water-soluble ammonium or alkali metal condensed phosphate or an alkaline earth metal condensed phosphate is prepared by reacting together a condensed phosphoric acid or a source thereof and a source of ammonium, alkali or alkaline earth metal or a mixture thereof, thereby to form an amorphous intermediate condensed phosphate material and calcining said intermediate material at a temperature below the liquefaction temperature of said crystalline condensed phosphate and for a time sufficient to produce said crystalline condensed phosphate.  The proportions of the ammonium, alkali metal or alkaline earth metal material and condensed phosphoric acid are adjusted so that the proportion present in the reaction product is substantially that present in the desired phosphate.  Mixed alkali metal or mixed alkaline earth metal condensed phosphates may be prepared, as can mixtures of different condensed phosphates, say of tripolyphosphate and trimetaphosphate.  The acid used is preferably added dropwise, with mixing, to a granular source at about 25 DEG  C.  The amorphous intermediate product is usually pulverulent but it may pass through a glue-like stage before solidification, in which case some of the already solidified material or of the desired crystalline phosphate may be recycled to the mixing stage. Calcination, after milling or grinding, is carried out at, e.g. above 260 DEG  C. Specified metal sources include oxides, hydroxides and carbonates of Na, K, Ca and Mg, nitrates and chlorides of Na, K, Li, Ca and Mg, and Li2CO3. Oxalates and citrates may be used and the acid employed is e.g. pyrophosphoric acid, metaphosphoric acid or tetraethyl pyrophosphoric acid.  In the examples Na4P2O7, K5P3O10, Na5P3O10, Na3P3O9, Ca2P2O7 and (Na, K)3P3O9 are prepared.

Title: Device and method for forming holes in blanks
Inventor: MARTIN GEORGE MERRILL
IPC: B26F1/44
Filed: 1962-03-26
Abstract: 963,856. Punching apparatus. M. D. MARTIN. March 26, 1962, No. 11480/62. Heading B4B. A method of forming a hole 5 in a blank 6 of compressible material comprises the steps of placing the blank between a male die and a female die, moving the dies together so as to cut the hole, engaging one face of the blank for limiting the climbing of the blank on the male die, and compressing the material around the hole on the other face of the blank into a recess 46 substantially simultaneously with the cutting of the hole. As shown, male and female dies 3, 4 are carried by rollers 1, 2 respectively, the dies having co-operating cutting edges 23, 24 overlapping substantially tangentially in cutting positions relatively to one another, the die 3 having a shoulder 22 spaced from the cutting edge 23 by a distance about equal to the thickness of the blank 6 to limit the climbing of the blank on the die 3 and to engage one face of the blank around the hole cut by the dies, a forming end 26 on the die 4 adapted to compress the material of the blank about the hole so as to form the recess 46. The shoulder 22 is formed at the end of a sleeve 16 secured around the body 9 of the die 3. The body 9 has a recess 14 to locate a projection 13 on a cutting disc 11 which is secured to the body 9 by a screw 12. The dies 3, 4 are secured to die holders 18, 29 formed in pairs each on a baseplate 32. Each plate 32 is secured on a mounting plate 33 by means of bolts 34 extending through elongate slots in the plato 32 so as to permit coarse axial adjustment of the plate 32 on the plate 33. Each plate 32 is adapted to be finely adjusted in the axial direction by means of cams 39 rotatably held in the corresponding plate 33. Each plate 33 is mounted at its ends by bolts 37 in grooves 38 in the respective rollers 1, 2. The cutting edge 24 is provided with serrations 27 to catch the cutout pieces from the blank. In operation, the pairs of dies are mounted on the rollers 1, 2 and finely adjusted. At this time, each die 3 has in place of its disc 11 an aligning button 43, Fig. 3, which fits on the end of the die body 9 and has a rounded edge 44, the outer diameter of which is sufficiently smaller than the diameter of the disc 11 to enter the die 3 with almost touching clearance. The rollers 1, 2 are then turned to move the buttons 43 into the respective dies 4. In this position, the bolts 37 are tightened. Then the rollers are turned to permit the removal of the buttons 43 and the attachment of the discs 11. Each disc 11 is softer than the cutting edge 24 of the corresponding die 4 and is larger by an almost cutting clearance. Thus, during the first penetration of the disc 11 into the cutting edge 24, the disc is sheared to exact fit for accurate cutting operation.
