[Class 102 (i)] [Also in Group XI] In a liquid fuel burning installation comprising one or more pressure atomizing burners of the type in which the discharge into the combustion chamber is regulated by varying the amount withdrawn from the burners through a return line, stagnation of the fuel in the return line when the burners are working at full capacity is prevented by supplying the fuel under pressure to the pumps supplying each group of one or more burners. Fig. 1 shows an installation comprising burners 2 which are supplied with fuel through pipes 3 by pumps 1 having their suction pipes 8 connected both to the return pipes. 14 of the burners and to branch pipes 9 leading from a pipe 11 through which fuel is circulated by a pump 21. The supply pressure at the burner is maintained constant by a byepass fitted with a pressure release valve 6. The discharge from the burnere is controlled by valves 10 which may be automatic pressure regulating devices, arranged in the pipe 9 or pipe 14. Non-return valves 4 in the, pipes 14 prevent the direct flow of fuel from the pipe 9 to the burners if the pumps 1 fail. In another installation the return pipe 14 is connected to the restricted portion of an ejector connecting the delivery pipe 3 and suction pipe 9 and the quantity of fuel passing through the ejector is regulated by an ordinary valve arranged in the supply or delivery pipe of the ejector. Fig. 4 shows an installation in which the output of the burner 2 is regulated by varying the steam pressure operating a piston pump 16 having its delivery pipe 18. and suction pipe 19 connected to the burner. The pipe 19 is also connected through a throttling member 17 to the pressure fuel supply pipe 11. The steam pressure may be regulated by a valve 22 operated by a spring-pressed diaphragm subjected on one side to the pressure of air supplied through a pipe 23. This air pressure is regulated by an escape valve 29 operated thermostatically by the fluid heated by the burner passing through a pipe 32. The pressure equalizing vessel 22a is arranged between the valve 22 and the pump. The throttling mernber 17 may comprise a casing 35, Fig. 5, fitted with a piston 36 which is subjected on its upper surface to the pressure of the fuel passing to the burner communicated through a passage 46 and on its lower side to the pressure of a spring 40 and the fuel passing from a pipe 38 connected to the pipe 9 through tapered apertures 43 in the piston to a pipe 39 leading to the suction side of the pipe 19.

Abstract: 875,137. Sorting coins. NUMISMATORS Ltd. Jan. 27, 1959 [Jan. 31, 1958; June 11, 1958], Nos. 3303/58 and 18700/58. Class 27 [Also in Group XIX] A coin sorting machine has a hopper 9 which is of horseshoe-magnet shape in plan and delivers mixed coins to an upwardly inclined belt 2 of material such as chrome leather, a constantly curving guide means 11 for causing the coins to form a single file and coin sorting means at a number of spaced stations for removing the largest coins at the first station, the next largest at the second station and so forth down to the smallest coin. The bend in the belt at the pulley 6 dislodges any coins which have lodged on or overlap one another. The coins are dislodged from the belt on to a downwardly sloping plate 12 which has a lower flange 13 and is twisted transversely so that the coins roll on the flange. At the first sorting station 14, a take-off knife 19 is spaced from the flange a distance lying between the diameters of the largest and next largest coins and has a pre-lifter 20 extending through a slot in the plate 12. The pre-lifter ensures that the edge of the coin is lifted ready to be tilted rapidly by the knife and thrown over the flange into the discharge shoot 25. Smaller coins passing the first station are sorted out at subsequent stations 15, 16 and the smallest coins may merely be discharged at the end of the sorting plate. In a modification, the coins are guided by a spiral flange to a circular rotating plate having a periphal flange against which the coins are urged by centrifugal force. Combined pre-lifter and take-off knives extend into annular grooves at different distances in from the flange and sort out the coins in decreasing order of size. If the coins are also to be counted, the coins as they move over the take-off knives interrupt a beam of light passing through a hole 21 and a light sensitive element 24 transmits a pulse to an electronic counting device (see Group XIX). For bulking the coins into batches, a gate is provided in the shoot 25 and is shifted by the counting device from one branch 29 to another branch 30 when a predetermined number of coins have passed.
