Title: Improvements in connection with controlling gear for steering machinery
IPC: B63H25/34
Filed: 1921-09-13
Abstract: 177,467. Wallace, W. Sept. 13, 1921. Steering-gear.-In controlling gear for steering- motors on ships which include a three-point floating lever wherein one point is attached to the controls, a second point is connected with the rudder, and a third point is coupled to the motor, the control end is adapted to be operated by a telemotor connection or mechanically from the hand-wheel as desired. The lever A has a connection B with the rudder, a connection C with a variable-speed hydraulic gear or variable delivery pump D. An electric, steam, or hydraulic motor may have its regulating-device similarly connected. The other end of the lever has a jaw-piece carrying on trunnions a nut E. The nut E engages the screw G on a shaft H. This shaft is adapted to be moved endwise in bearings I, J by the telemotor gear R, either directly or through levers Q engaging a collar P. When the shaft is so moved it moves the lever A. At the same time it slides in the bevel-wheel K, which is keyed or splined thereto. For operating by hand, the wheel N rotates the shaft H through the bevel-wheels L, K, and thus causes the nut E to traverse the screw G to move the lever. To prevent the shaft from rotating when it should move only endwise or vice versa, locking-devices T are provided. In a modification, the control is applied at the centre of the lever and the connection C attached to the end.

Title: Improvements in sheet feeding mechanism for printing machines and the like
IPC: B65H3/08
Filed: 1924-10-14
Abstract: 243,130. Cleathero, E. T. Oct. 14, 1924. Sheet separators, carriers, and guides.-Sheets are fed to a printing or like machine by a machine which enables the sheet to be fed directly to the top or bottom of the impression cylinder, or to be fed in a backward direction to back stops, and then reversed to be forwarded face-side downwards to the printing or like machine. The machine is adaptable for dealing with sheets of different sizes. The top sheet is separated from the pile by means of a series of suction separators 1, Fig. 4, mounted on a tube 2 carried by arms 3 pivoted to links 4 pivoted at 6 to an adjustable slide 7, Fig. 1. The arms 3 are also pivoted to links 21 connected to oscillating arms 20 on a shaft 19. The separators 1 act on the rear edge of the pile, and as the arms 20 moved in a clockwise direction the separators increase their inclination to the top of the pile. thus bending up the rear edges of the sheet, until screws 5 contact with the links 4. when further movement of the arms 20 raises the separators from the pile. By adjustment of the screws 5, the machine may be set to deal with sheets of different thicknesses. The separation of the top sheet is assisted by an air blast from a tube 29, and the remaining sheets are pressed, while the top sheet is removed, by a holder 9 mounted on the lever 11 oscillated by a cam 13 and spring-controlled rod 14. As the holder 9 moves to the pile a spring 24 depresses it, but a fixed runner 26 and cam 25 keep the holder 9 raised as it moves from the pile. The front edge of the sheet is engaged by a suction separator 57, Fig. 1, actuated by parallel links to feed the separated sheet to rollers 34, 52. These rollers may be arranged in conjunction with tapes to feed the sheet to the underside of a printing-machine, or direct to the top of a printing-machine. As shown in Fig. 10 the sheet may be fed to the upper feed board 40 to backstops 36, and the sheet is then reversed and advanced by a second set of suction separators 57, or, as shown in Fig. 1, the board 40 may take the form of an oscillating set of laths with pulleys 41, which bring the sheet into contact with pulleys 39 acting in conjunction with tapes and pulleys 39<a> to reverse the sheet and advance it to the printing-machine.

Patent GB-1523390-A (GB)
Title: Fuel system
IPC: F02D35/00
Filed: 1976-06-11
Abstract: 1523390 Pressure fed carburetters BORG WARNER CORP 11 June 1976 [15 Sept 1975] 24358/76 Heading F1B [Also in Division G3]  A fuel supply system comprises a regulator 12 including a body 51 having an inlet port 52 connected to a fuel source 11, an outlet port 53, and a return port 54 connected with a fuel charge forming apparatus 14 for receiving excess fuel therefrom, a spool 61 movable in the body 51 and having means 72 for throttling flow between the return and outlet ports 54, 53, a pressure regulator controlling flow from the return port 54 to a control chamber 66 in communication with the spool 51 from whence it is exhausted to the outlet port 53 through a restriction 68. The pressure regulator is formed by a diaphragm 76 biased by a spring 79 to co-operate with a port 77. In use, fuel from the outlet port 53 is fed by a pump 13 to a tube 27 extending across an air supply passage 24 and having an opening 31 facing upstream of the passage, and excess fuel is returned thence to the return port 54. At equilibrium the diaphragm 76 takes up a position so that flow through the port 77 is equal to that through the restriction 68; the spool 51 is stationary and excess fuel is returned to the outlet port past the throttle means 72. When more fuel is drawn from the opening 31 so that the pressure at port 54 falls, the diaphragm 76 moves to reduce the flow through the port 77, so that the pressure in the control chamber 66 falls, and the spool 51 moves to reduce the flow past throttle means 72; thus the pressure in port 54 rises and this acts on the diaphragm to increase the flow through the port 77 until it is again equal to that through the restriction 68 and a new equilibrium position of the spool 51 is established. Likewise if the amount of fuel returning from the chargeforming means 14 increases the spool is moved to increase the flow past throttle means 72. The spring 79 has a low rate so that the force biasing the diaphragm 76 against the port 77 is substantially independent of diaphragm position. This force serves to determine the pressure in the control chamber 66 at equilibrium and ultimately to determine the fuel/air ratio of the charge formed in the means 14; this force may be pre-set by means of screw 82. Alternatively, Fig. 3 (not shown), the force on the diaphragm 76 may be adjusted continuously by a coil (84) in response to parameters such as engine temperature, oxygen content of exhaust gases, or atmospheric pressure.

Abstract: 683,725. Regulating; pumps. DAIMLERBENZ AKT.-GES. Oct. 6, 1950 [Oct. 7, 1949], No. 24505/50. Classes 7 (ii) and 7 (vi). In an engine wherein a supercharging blower is cut in at a predetermined position of the fuel control means, a time-delay device retards increase of fuel while the blower is being cut in. The accelerator pedal a is connected by a link b and lost motion connection c to the fuel -pump control rod d. At the point A' a stop q on the link b contacts a lever p to actuate an exhaust by-pass valve n to bring into action a supercharging blower h driven by an exhaust turbine f, and a lever r connected to a hydraulic dash-pot device t contacts the casing c' to hold the lever d stationary while lost motion occurs in the connection c and the spring c<SP>2</SP> is compressed. The rod d is then moved forward slowly by the spring c<SP>2</SP> under the control of the dash-pot t which is arranged so that the rate of increase of fuel corresponds to the rate of increase of the air flow while the blower is gaining speed. The dash-pot comprises a piston u in a liquid filled cylinder having the opposite ends connected through a small orifice v. A non-return valve x permits a quick return of the piston u if the dash-pot is to operate only on cutting in of the pump.

Title: Improvements in glass shaping machines
IPC: C03B9/14
Filed: 1919-10-08
Abstract: 165,875. Moorshead, T. C. Oct. 8, 1919. Blowing; delivering molten metal.-Relates to a glass-bottle &c. making machine of the automatic continuously-rotating frame type. The parts are operated by cams, mounted on a central column 7, Fig. 1, in the usual way, except the plunger 158, which is pneumatically operated as shown. According to the invention, the molted metal flows continously from a hole 5 in a tank' 4 through a fixed ring 63 into each parison mould 60 as it arrives in the filling position. Each parison mould 60 is mounted on a carriage 41, Figs. 1 and 5, which is moved by gearing along an inclined track 45 extending over a small arc of the main frame. This movement takes place at the filling point and is timed so that when the mould reaches the filling point, the carriage 41 commences to move along the track 45. The result is that the mould remains below the hole 5 and rises to meet the falling stream of glass. By the time the mould has reached the upper position U, Fig. 5, the next mould has arrived at the position L, close to it. At this moment, shears 77 cut the stream of molten glass and the movement of the main frame carries the upper mould U from under the hole 5 and brings the lower mould L below it, before the falling stream reaches the lower level. The lower mould then rises vertically till its carriage 41 reaches the end of its track 45, when the mould is carried forward again. Before reaching the filling point again, each carriage 41 is moved to the bottom of its track 45. In this way each parison mould is kept moving continuously, either rotating with the main frame or rising vertically during the filling operation. Each parison mould is provided with a guide 61, and the shears 77 are formed with depending flanges 78, Fig. 18, to prevent lateral splashing of the molten metal at the moment of cut-off. When charged, the parison mould 60 is withdrawn below the plunger 158, which descends through the neck mould 142. The blowing-head 198 is moved forward when the plunger 158 rises and air is introduced into the parison. The parison mould 60 is then opened and the finishing- mould 170 and bottom 187 moved into place. On the completion of the blowing, the finishing-mould is moved radially outwards over the parison mould, which is then in the lower position. The mould is opened and the finished article is removed by rotating grippers which place it on a conveyer &c. Cooling-air passes through ports 17, 18 as shown by the arrows. Access may be had to the cams &c. for adjustment from the central column 7 through holes 22.

Abstract: 334,684. Neilson, T., and Marshall, J. Aug. 14, 1929. Ventilators; valve apparatus.-An air-distributing device adapted to be rotated by the reaction of the air issuing from it is in communication with a pair of ducts supplying cold and warm air, the proportions of cold and warm air being determined by valve means. The apparatus shown comprises four hollow vanes 1 mounted radially on a rotatable cylindrical casing 4 which is suspended by means of a frusto-conical bottom 10 from a ball-bearing 11 carried by a spider 12 supported from the bottom of an air chamber casing 15. Air is admitted to the air chamber bv two inlets s communicating with the hot and cold air ducts, one of which inlets is shown at 21. A single, flap valve 22 operated by a handle 24 controls the two inlets differentially and so varies the proportions of hot and cold air. The air passes into the casing 4 and thence to the hollow vanes, from which it issues by slot-like apertures extending along one edge. An apertured sleeve 5 in the casing 4 forms a check valve, and is adjustable by a handle 6 to vary the amount of air delivered. Instead of forming a unitary structure the distributing device and the hot and cold air proportioning means may be separate. The proportioning and check valves may be operated through remote control mechanism, such as a Bowden cable or electrical means, or they may be thermostatically controlled-
