Title: Improvements in or relating to airport fueling apparatus
IPC: B64F1/28
Filed: 1948-11-26
Abstract: 659,394. Counting-apparatus. WAYNE PUMP CO. Nov. 26, 1948, No. 30711. Convention date, Dec. 31, 1947. [Class 106 (i)] [Also in Groups XVIII and XXIX] In a liquid dispensing device for fuelling aircraft (see Group XVIII) which includes a meter for measuring the flow of liquid and a register for recording the amount, it is required to register only the amount of liquid dispensed even though some is pumped back after a dispensing operation, and the meter is therefore adapted to drive the counters of the register through a gear train which is operable only when the liquid is under pressure as it is dispensed. The meter drives a shaft 290 (Fig. 11) and the counters are driven by a gear 282 pivoted at 268 to the casing 254. A lower lever 266 is pivoted at 268 and carries a pin 294 which - can meet the edge of an upper lever 276 also pivoted at 268 and carrying an idler gear 278 in mesh with the gear 282. Another idler gear 284 is pivoted to the casing at 286 and meshes with a gear 288 on the shaft 290. A spring 292 pulls the lower lever 266 anti-clockwise, causing the pin 294 to turn the upper lever 276 anticlockwise, so holding the gears 278 and 284 disengaged. The armature of a solenoid 258 is connected by an operating-rod 262 to the lower lever 266 at the pivot 264 so that, when the solenoid is energized, the lever 266 will move clockwise and, through a spring 272, move the upper lever 276 clockwise, so bringing the idler gear 278 into mesh with the idler gear 284, the movement being limited by an adjustable stop 281. The solenoid is energized through a switch which is closed by liquid pressure during dispensing and opens as soon as dispensing ceases. Manual operation is also catered for by a push-button 294 which, when pressed, causes a plunger 300 to move the lower lever 266 and engage the gears as described. Fig. 15 shows an engaging and disengaging mechanism which incorporates reversing means. The meter drives a shaft 334 and the counters are driven by a gear 318 pivoted at 316 to the casing 308. A lever 314 is also pivoted at 316 and is urged anti-clockwise by a spring 324 and can be moved clockwise by the solenoid-operated rod 262. When the lever 314 is in the latter position a gear 332 on the shaft 334 drives the gear 318 through idler gears 328 and 320; when in the former position the idler gears 328 and 320 are disengaged. An idler gear 338 in mesh with the gear 318 is carried on a reverse'lever 336 which is pivoted at 316 and which, when moved anti-clockwise by a pull-rod 346, brings the idler gear into mesh with the gear 332, whereby the gear 318 is driven in the reverse direction. The anti-clockwise movement of the lever 336 causes the disengagement of the idler gears 328 and 320 through its edge striking an upturned lug 342 on the lever 314.

Filed: 1937-11-09
Abstract: 489,684. Rolling. UNITED ENGINEERING & FOUNDRY CO. Nov. 9, 1937, No. 30732. Convention date, Sept. 11. [Class 83 (iv)] A mill plant comprises a hot rolling mill 3, Fig. 1, followed in line by a continuous mill 18, Fig. 2, the rolls of which can be changed to act first as a hot mill and then as a cold mill, so that a process can be carried out as follows. An ingot from a trolly 1 proceeds along a feed table 2 to repeated back-and-forth rolling in the reversing mill 3 until reduced to slabs, the ends of which are cropped in shears 6 including a gauge 7. Each slab is then pushed by 9 on to an endless chain conveyer 8 to a piler 11, a pile being transferred by a crane hook 12 back to a support 14 where each slab is pushed into a reheater 13 and then each slab is repassed through the same mill 3 until reduced to plate. Each plate is then sheared at 6 and conveyed and hot rolled to strip in the mill 18 and coiled at 21, the coils being passed to a conveyer 24 for self annealing and then through pickling apparatus 34 while the hot rolls are exchanged for cold rolls in the mill 18 and the table sections 27 and 31 are removed to uncover an uncoiler 28 and a coiler 32, then passing the cold pickled coil into the uncoiler 28 and through the now cold mill 18, while at the same time the mill 3 is operating as previously on fresh ingots and slabs. The reciprocating pushers 16 continue to push the top slab off the pile into the furnace, the pile support rising one slab thickness after each push so that a succession of slabs are being pushed in and delivered out of the other end of the reheater 13 on to the table 2. The piles formed at 11 may be stored and removed by the crane hook 12 for reheating when required. There are two coilers at 21 with a gate 22 to deflect the strip to one or other of the coilers. The uncoiler under the removable table section 27 is in Fig. 3, and the tension coiler under the removable table section 31 is in Fig. 4 (not shown). Specification 483,397, [Group XXX], is referred to.

Title: Improvements in the production of iron
IPC: C21B5/02
Filed: 1936-11-14
Abstract: Iron with a titanium content exceeding 0,6 per cent is produced in a coke blast-furnace by the use of a basic slag of which calcium aluminates constitute more than 50 per cent.  A furnace temperature of 1600 DEG  C. or more, preferably one of 1800 DEG  C. or over, is employed.  Bauxite, containing titanium dioxide, is preferably employed for the charge, in which case titanium ores such as ilmenite or rutile need be added only to a small extent or not at all.  As the iron content of bauxite is low, another source of iron, preferably scrap iron, may be added.  Large quantities of slag, which may amount to three times the quantity of iron, are employed.  In an example, the mixture consists of 3000 kilograms of bauxite, 300 kilograms of ilmenite, 3750 kilograms of scrap, and 3000 kilograms of limestone. In a further example, the mixture contains no ilmenite, and consists of 3000 kilograms each of bauxite and limestone and 1700 kilograms of scrap.

Abstract: 495,351. Sharpening knives. INDUSTRIE AKT.-GES. ALLEGRO. Nov. 12, 1937, No. 31169. Convention date, Nov. 12, 1936. [Class 60] A device for sharpening knives comprises two sharpening discs driven, through gearing, by the longitudinal reciprocation of the knife in contact with the discs. In the construction shown in Fig. 1, the device comprises a casing 2 in which are rotatably mounted two overlapping sharpening discs 1, each provided with a toothed ring 7 the rings being engaged respectively by pinions 8 on shafts 6 rotatably supported in tongues 9 of the casing and in pivoted plates 11. The shafts 6 carry friction knobs 5 which engage the sides of a knife 4, which lies in a slot 3 in the casing and is reciprocated in contact with the discs ; the knobs 5 are pressed by springs 13 against the knife and serve to rotate the discs 1, either in the same direction with reversal on reversal of the movement of the knife as shown in Fig. 1, or in opposite directions. The sharpening angle between the discs is made variable by mounting the discs on arms 14 pivoted at 15 and acted upon by a tension spring 16 ; a handle 17 may be used to hold the discs at any required angle setting, which setting may be read from a pointer 18 and a scale 19, and catches may be provided to hold the discs at any desired angle setting. In the construction shown in Figs. 2 and 3, the discs 1 both rotate in the same direction, the direction being unchanged upon reversal of the movement of the knife, and for this purpose the discs are driven, through toothed or friction rings 23 and through pinions 22 carried by the shafts 6, which are pivoted at 20, so as to rock when the movement of the knife is reversed. In a modification, the knife is carried by clamps on a bar formed with rack teeth on its edges for engagement with pinions on the shafts 6.
