Title: Fuel injection valves for internal combustion engines
IPC: F02M47/02

Abstract: 1,219,694. I.C. engine fuel injectors. SULZER BROS. Ltd. July 30, 1969 [July 31, 1968], No.38265/69. Heading F1B. An I.C. engine fuel injection valve comprises a valve needle 103, Fig. 3, guided at 34c in a housing 10a and co-operating with a valve seat 32a in the housing, the end of the valve needle remote from the seat being a greater diameter than the seat; a forward fuel chamber 115 connected via ducts 114, 15 to a fuel line in which a constant pressure of 500 to 1000 atmospheres or more is maintained by a fuel pump; and a spool valve 100 having a control edge 111 co-operating with a control edge 112 to allow fuel to enter a rear fuel chamber 116 from the duct 15. When a solenoid (not shown) is energized to cause a core 23 to attract the disc-like end 102 of the spool valve 100 and thereby lift the spool valve, the control edges 111, 112 block the flow of fuel from the duct 15 to the rear fuel chamber 116, and at the same time a conical end 106 of the spool valve is lifted from a seat 105 to allow fuel to flow from the rear fuel chamber via ducts 107, 108, 104 to the engine cylinder. The resultant fall in pressure above the upper end of the valve needle 103 allows the fuel pressure in the forward fuel chamber 115 to raise the valve needle from the seat 32a to permit fuel to flow via the ducts 15, 114 and the forward fuel chamber into the engine cylinder. The rapid movement of the valve needle 103 is cushioned by a stop ring 117. In another embodiment, Figs. 1 and 2 (not shown), the spool valve (26) slides within a bore (40) in the valve needle (35), the flow of fuel into the rear fuel chamber (54) being controlled by a control edge (48) on the spool valve co-operating with a control edge (46) formed within the valve needle. The stop ring (52) for cushioning the rapid upward movement of the valve needle (35) may be replaced by a stick of belleville washers (120), Fig. 4 (not shown).

IPC: B65H23/02
Filed: 1966-08-31
Abstract: 1,154,071. Feeding webs. FIRESTONE TIRE & RUBBER CO. 31 Aug., 1966 [7 Sept., 1965], No. 38933/66. Heading B8R. In apparatus for transversely guiding and stretching continuous moving web material, the web 39 passes over a curved-axis roller 24 the ends of which can be independently moved along an arcuate path so that the roller presents a lesser or greater curvature to the web for stretching the web, and the roller 24 is carried by a frame 10, 11 pivoted at 16 and operated so as to move the roller transversely of the web for guiding the web. The roller 24 comprises a sleeve of flexible rubbery or plastic material rotatably mounted on a curved axle 23. At each end, the axle 23 is carried by a support 22 pivoted at 21 to a bracket 20 attached to the adjacent ends of frame members 10, 11. Attached to the support 22 is an arm 25 connected by a link 26 to the piston of an hydraulic cylinder 30. An adjustable feeler finger 40 is situated at each edge of the web, each finger controlling the cylinder 30 at its side of the web. If a web edge presses against its feeler, the piston is caused to be projected to move the roller axle 23 so that the roller 24 presents a lesser curvature to the web thus tending to narrow the web and the frame 10, 11 pivots about the axes 16 to move the web edge transversely away from the feeler. The reverse occurs if the web edge is not touching its feeler. If both pistons are operated in opposite direction substantially only transverse movement of the roller 24 occurs, and if they are operated in the same direction, arcuate movement only of the roller takes place. A second roller similar to roller 24 may be mounted on another support 22a attached to bracket 20 and connected by an arm 25a to link 26, the web passing over the first roller 24 and under the second roller.

[Also in Group XXIII] In a brush-making machine each work-holder is moved in space to present the workpiece to a drilling or tufting tool in a sequential manner dependent upon the programming of a series of punched cards that are presented to sensing devices, each of which controls the moment of and duration of connection between a continuously reciprocating bar 47 and the rack 45 of a rack and pinion drive in a drive-controlling movement of the holder in one of three dimensions in space. A fully programmed series of punched plates A are delivered plate by plate at predetermined intervals to the sensing device. The device consists of a vertically movable holder in which are movable spring-loaded fingers that correspond in number and position to all the possible programme holes that can be punched in a plate. When the holder is brought to bear against the plate a finger 48a will extend through the plate to depress a spring- biased pawl 47a on the reciprocating lever 47 as the pawl passes beneath the finger. The pawl 47a engages, dependent on the programme plate, a toothed series of teeth 45a on the rack bar 45 of the rack and pinion drive connected to the work-holder to cause a movement thereof in timing and extent appropriate to the point of engagement of the pawl 47a in the series of teeth 45a. The pawl 47a only establishes connection between the levers 47 and 45 in one direction of movement. Each device controls two sets of associated levers to allow sequentially of a course and a fine movement of the associated work-holder.

Title: Improvements in or relating to oxygen supply systems
Inventor: FITT PETER WILLIAM
IPC: F17C9/02
Filed: 1958-12-11
Abstract: 862,080. Respiratory appliances. NORMALAIR Ltd. Nov. 17, 1959 [Dec. 11, 1958], No. 39941/58. Class 81(2). An oxygen supply apparatus, particularly for high altitude use in aircraft, includes a liquid oxygen converter and two delivery conduits, both of which are supplied until a predetermined reserve of liquid oxygen remains, after which only one conduit is supplied. Thus, in aircraft, both passengers and crew would initially receive oxygen but as the supply becomes exhausted, only the crew receive it. The liquid oxygen container 1 is filled through a connection 7 so that it flows past non-return valve 8 and enters the container through tube 5. The action of connecting the supply lifts a valve 9 so that tube 15 is closed but the container 1 is vented to atmosphere through outlet 12. When the supply is disconnected, liquid oxygen flows through heat-exchanger 16, where it is vaporized so that the pressure increases and gaseous oxygen flows through non-return valve 17 to pipe 15. This continues until the pressure is sufficient to close the valve 18 by means of aneroid 19, after which no further flow or increase in pressure normally takes place. However, if excessive pressure is generated, an aneroid 21 opens valve 22 and the gas escapes through a relief valve 26, Under normal conditions, when the pressure in the container is high, the crew receives gaseous oxygen through conduit 10, pipe 15, valve 22, pipe 24 and the delivery conduit 25. At the same time liquid oxygen, through outlet 14, is vaporized in coil 32 and passes through valve 35 and superheating coil 38 to the passenger delivery conduit 39. When the level of the supply falls below the outlet 14, this supply is interrupted and the drop in pressure allows valve 35 to close, so cutting off the supply to the passengers. However, the crew continue to be supplied, in the manner described previously, until the pressure drops to a point at which valve 22 closes and a differential valve 42 is permitted to open, whereupon liquid oxygen flows from outlet 4 and is vaporized in the conduit 25.
