Title: Improvements in or relating to suction producing systems for use with printing or other machines
IPC: B65H3/08
Filed: 1952-10-01
Abstract: 742,256. Feeding sheets. FABER & SCHLEI. CHER AKT.-GES. Oct. 1, 1952 [Oct. 3, 1951], No. 24546/52. Class 100 (1). [Also in Group XXVIII] In a machine, such as a printing-machine, in which two or more suction devices are served by only one single-stage suction pump, means is provided whereby the air pressure in one suction conduit can be regulated independently of that in the others. As shown, conduits 4, 6 are connected, respectively, to the suction and pressure ports 3, 5 of a rotary pump 2, both conduits leading to a rotary valve 7 operable by a lever 8. With the valve open, the conduits communicate with further conduits 4a, 6a leading to sheet-feeding apparatus such as a separator 41 and blower 42, and when the valve is closed, compressed air from conduit 6 is allowed to escape through a venturi tube 9. A second suction conduit 13 leading from a suction roller 12 joins the suction conduit 4 through regulating valves 14 and 11  which are of substantially the same construction. The valve 11, Fig. 2, has four internallythreaded sockets in which the conduits 4, 13, and a valve bearing 16 are screwed. A valve 18, having a spindle 17 guided in the bearing 16, is pressed by a spring 20 against a seating to close the suction conduit 13, the screwed bearing 16 serving to regulate the pressure in the valve. The vacuum created in the conduit 4 overcomes the pressure of the spring 20, so that the valve 18 is opened and suction established to the roller 12. The difference in the intensity of the suction in the two branches 4 and 13 depends upon the pressure exerted by the spring 20. In the valve 14 the socket facing the spring-pressed valve 18 is connected to atmosphere through a pipe 40. In a modification, an additional opening which normally serves for the influx of air into the pump 2 is connected by a conduit to the conduit 13 between the valves 11, 14. In this case, when the valve 7 is closed, venturi tubes allow both the pressure and suction conduits 6, 4 to communicate with the atmosphere.

Abstract: 1,183,563. Compressors driven by compressed gas engines. O.H. DRAGER [trading as DRAGERWERK, HEINR, & BERNH DRAGER] . May 24, 1968 [May 24, 1967], No.25057/68. Headings F1M and F1N. A compressor has a small compression piston 8 reciprocated in a compression chamber 4 by an integral large piston 8<SP>1</SP> the reciprocation of the piston 8<SP>1</SP> in a cylinder 16 being caused by continuously supplying pressurized gas to a chamber 1 at one end of the piston while a chamber 9 at the other end is alternately vented and pressurized with gas from the chamber 1. In the position shown, the chamber 9 is vented through bores 14, 15 in the large piston 8<SP>1</SP> and a pressure release bore 17 in the cylinder 16. The gas supplied to the chamber 1 thus causes a compression stroke against the action of a spring 7. At the end of the stroke the chambers 1 and 9 are connected by bores 12, 13 in the piston 8<SP>1</SP> whereby chamber 9 is pressurized. Pressurization of the chamber 9 combined with the action of the spring 7 and the pressure in the chamber 4 causes a return stroke of the pistons, and the cycle is repeated. Gas to be compressed in the chamber 4 may be the same or a different gas to that used to drive the piston 8<SP>1</SP>. In a modification the bores 12, 13 are opened and closed by a valve responsive to the movement of the pistons and the bore 17 continuously vented the chamber 9 through a throttle. In Fig.2 (not shown) the pressurization and venting of the chamber 9 is via ports in the cylinder controlled by the movement of the piston 8<SP>1</SP>. The venting may be controlled by a manually operated valve.

Filed: 1938-08-29
Abstract: 516,953. Winding threads &c. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN. Aug. 29, 1938, No. 25295. Convention date, Aug. 28, 1937. [Class 120 (ii)] Thread &c. is wound on to a spool or holder by being fed thereto under tension produced by the rotating spool in a direction which is always at an acute angle to the axis of the spool and the thread is periodically engaged by fingers projecting from a disc rotating about an axis substantially transverse to the axis of the spool so that the thread is caused to traverse the spool in a direction lengthwise thereof by each of the fingers which subsequently disengages the thread to allow it to traverse the spool freely in the reverse direction until it is engaged by the next succeeding finger on the disc. As shown, the thread 13 is wound on the spool 14 rotatable on a vertical axis and is traversed down the spool by fingers 30 pivotally mounted round the periphery of a rotating disc 23. Each finger as it moves downwards engages the thread 13 so that it is wound spirally on the spool and as the finger nears the lower end of the spool it engages a lug 35 which swings the finger upwards; the thread is thus released and, owing to the inclined direction in which it passes to the spool, is wound spirally upwards until it reaches the top of the spool when it is engaged by the next succeeding finger 30. The fingers are yieldingly held against stops 33 on the disc by springs 32. The spool may be arranged to rotate on a horizontal axis. The thread 13, e.g., of glass from a feeder 10, passes over a fixed guide 15 located nearer one end of the spool than the other and the guide may be arranged to supply a coating material to the thread. The Specification as open to inspection under Sect. 91 comprises also a modification in which the thread is traversed in both directions by fingers mounted on a pair of coaxial discs rotating in opposite directions and one in which the fingers are fixed to the disc in which case the disc is disposed so that the fingers slide off the thread and release it at the end of the spool. This subject-matter does not appear in the Specification as accepted.

Abstract: 703,694. Photo-electric sorters. NATIONAL COAL BOARD, WHELAN P. F., and EDMONDS, DE L. E. Oct. 15, 1951 [Oct. 18, 1950], No. 25410/50. Class 40 (3). [Also in Group XXIX] Articles are sorted by determining photoelectrically the relative specular and diffuse reflectivity of each object. As shown, lumps of coal, the bright ones of which are to be diverted into a compartment 15 pass one at a time down a shoot into a compartment 14. Each passes over a narrow slit 1A in the shoot and the underside of the slit is illuminated by a source 3. Two photo-cells 4, 5 are provided which receive light reflected from the coal. Cell 4 receives specularly reflected light with the assistance of a reflector 4A and cell 5 which is situated in a reflector 5A receives diffused light. The output of the cells are compared in an amplifier 6 the output of which may depend on the difference of the cell responses or response of one cell and a multiple of the other. This output operates on an electromagnetically controlled valve allowing a fluid pressure servo system (vide infra) to move a deflecting flap 12. A time delay device may be incorporated in the amplifier circuit to allow the coal to reach the flap. In the embodiment of Fig. 2 (not shown) two separate light beams alternately chopped by a rotating wheel, Fig. 5 (not shown) are used. The first projects light at right angles to the conveyer surface, the second at 45 degrees. A single photo-cell is employed, the axis of the reflector being at 45 degrees to the conveyer surface, so that this cell receives alternately diffusely and specularly reflected light from the first and second light sources respectively. The amplifier compares the two sets of pulses and operation of the valve is as for Fig. 1. In the embodiment of Fig. 3 a single source 3 directs light from the reflector 19 through a lens 21 on to the aperture in the conveyer. Specularly reflected light is teflected back through the centre of the lens to a cell 4 while diffusely reflected light is received through the outside of the lens by cell 5. Otherwise operation is as for Fig. 1. In the arrangement of Figs. 4 and 7 (not shown) the light source and the lens are arranged as in Fig. 3 but specularly reflected light in passing back through the centre of the lens is directed by a prism through an outer row of apertures in a rotating disc ; diffusely reflected light passes through an inner row. This cell 24 receives alternately specularly and diffusely reflected light. Operation is otherwise as in the embodiment described in connection with Fig. 2.
