IPC: B41F31/16
Filed: 1924-05-15
Abstract: 233,884. Storey, W. H. May 15, 1924. Ink-ribbon mechanism.-(1) Feed and automatic reversal. In rotary duplicating-machines employing an ink ribbon, the feed is automatically reversed, without tautening the ink ribbon, by means of feelers adapted on entering slots in the spools to set abutments in the path of a check-pawl for the spool ratchet-wheels, the check and feed pawls 1 being thereupon thrown over to reverse the feed. The spools 40, 41 are mounted on the ends of the duplicator cylinder and are provided with ratchet-wheels 42, 43 cooperating with teeth 31, 32 on a feedpawl 30, and teeth 26, 26<1> on a check-pawl 20 respectively, the feed-pawl and check-pawl being pivoted at 15 to a slide 13 which moves in a guide 14 on the cylinder end A and is actuated by an eccentric 10 on the cylinder shaft 1. A spring 25 is connected to the feed-pawl and a rod 23 having a finger which passes through a slot 22 in the check-pawl and carries a roller 24 co-operating with inclines 33, 34 on the feedpawl. Spring-urged feelers 60, 60', pivoted on a bracket 62 on the cylinder end A and connected by a link 65, are adapted, when the ribbon has been unwound from the associated spool, to enter a slot 45 in the spool. The feelers have abutments 64 for engaging the teeth of the checkpawl. In operation, assuming that the ribbon has been unwound from the spool 40, the feeler 60 enters the slot in the spool, and the abutment 64 moves into the path of the tooth 26<1>. When the slide 13 descends, the check-pawl is rocked abnormally, and the roller 24 engages the incline 33 and then rides on to the incline 34, the check and feed pawls being thereby thrown over to reverse the feed. A. brake consisting of a leaf spring engages the spool heads 40d, Fig. 6, preferably at points remote from the axes. The spring serves also to maintain the spools in position for co-operating with the feed-devices. (2) Spools. The spools 40, 41 are provided with detachable heads 40d, Fig. 6, having slit parts 44 for engaging the spools. The ratchet-wheels 42 are secured to the spools, so that on removing the spools the feed and check-pawls are. operated noiselessly. The sheath 40<1>, Fig. 3, and rod described in Specification 134,673 are employed for attaching the ribbon to the spools. The sheaths are now formed with slots registering with the slots 45, and to ensure the sheaths being placed in the correct position on the associated spool, the two sheaths have projections arranged in different positions and adapted to engage slots 44a in the associated spools. To ensure the spools being mounted in correct position, the pivot pins and holes of one spools are made larger than those of the other spool.

Filed: 1944-06-26
Abstract: 580,322. Compressors. ESCHER, WYSS MASCHINENFABRIKEN AKT.-GES. June 26 1944, No. 12105. Convention date, June 26, 1943. [Class 110 (i)] In a centrifugal or axial flow compressor, surging at partial load is prevented by passing some of the fluid from the outlet of each stage or group of stages to the inlet thereto, beginning with the last stage or group of stages and working back through the previous stages or groups of stages in succession as the output is lowered. The low pressure stage 1 has a valve 7 which can be opened by the cam 6 to allow fluid to pass from the outlet of the stage through ports 8, 8<1> and 9 to the inlet. Similar means are provided for the stages 2, 3. The cams 6 are operated by the servometer 4 which is controlled by a volume governor (not shown), and the valves 14, 10, 7 are opened in succession as output falls. A separate servometer may be employed for each valve, the servomotors being arranged to operate in the correct sequence. Returned fluid may be given a component of velocity in the direction of rotation of the impeller by constructing the ports 9, 13, 17 non-radially, or by the use of deflecting plates after each port. Intercoolers may be provided between the stages or groups of stages, the bye-passed fluid being taken from the delivery side of each intercooler.

Title: Liquid fuel injection pumps
Inventor: GLIKIN PAUL EDGAR
IPC: F02M59/36
Filed: 1960-04-06
Abstract: 923,105. Fuel injection pumps. C.A.V. Ltd. May 17, 1961 [April 6, 1960], No. 12139/60. Class 102(1). A combined fuel injection pump and governor for a single-cylinder I.C. engine comprises a cam-actuated injection plunger 8 and hydraulically controlled valve means 27. During the injection stroke of plunger 8, fuel above a piston 9 moves a piston valve 19 to open passages 21, 22 and expose piston valve 27 to pressure, fuel also passing from above to below piston 9 via passage 22. Valve 27 moves upwardly until a groove 29 registers with a groove 32 thereby connecting a spill port 33 to a reservoir 16 and terminating injection. During the return stroke by a spring 13 fuel passes from beneath piston 9 to injection chamber 4 via a passage 41 and also enters the space above piston 9 from reservoir 16 via a valve 17. On the next injection stroke the quantity of fuel injected depends upon the distance between grooves 29 and 32 controlling spill port 33. This distance depends upon the rate of return movement of valve 27 by a spring 28, which rate is determined by the setting of throttle valves 34, 36, passages 21, 22 being closed. Valve 36 only becomes effective during the last part of the movement of valve 27 thereby providing a rapid run-up '. Upward movement of valve 27 is limited by a spill port 43 and downward movement, and hence maximum delivery, by an adjustable nut 44. The required engine speed is determined by the setting of throttle valves 34, 36. In another embodiment, Fig. 2 (not shown), the chamber beneath piston 9 and various valves are omitted, inlet ports in the sides of cylinders 4 and 7 being controlled by plunger 8 and piston 9, respectively. For multi-cylinder engines several pump-governor assemblies may be formed in a common housing.
