Title: Improvements in or relating to pasting mechanism for stitching machines
IPC: B42B2/00
Filed: 1930-06-30
Abstract: <PICT:0353654/III/1> <PICT:0353654/III/2> In a book-stitching machine of the type in which the sheets are carried to stitching-position by a swinging carrier, adhesive-applying mechanism, arranged so that the adhesive-applying part is moved into and out of contact with a supply member without sliding movement between the parts, is provided.  The mechanism is preferably arranged beneath the operating-table of the machine.  The paste-applying member 9 is rigidly connected to a lever 10 journalled in levers 11 pivoted at 12 and adapted to be moved by means of toothed segments 13, 6a, the latter being carried by a bell-crank lever 6 which is actuated by a spring 28 under the control of a cam 4 on the main shaft 2 of the machine.  The lever 6 is normally held against actuation by the spring by means of a lever 19 pivoted on a lever 5 and engaging a stop 20 on the lever 6, the two being held in engagement by a spring 19b.  The lever 19 is released by a lever 22 actuated by a treadle 22a to permit the lever 6 to be moved by the cam 4.  Simultaneously with the release of the lever 22, a projection 22b on the lever 22 turns a lever 21 which trips the lever 10 and paste-applying member 9.  The member 9 is adapted to be held in the paste-applying and inoperative position, or the position in which the member contacts with a paste-supply roller 18 by stops 25, 26 thereon, a stop 27 on one lever 11, and a spring 24.  Tripping of the lever 10 by the lever 21 causes the member 9 to contact with the roller 18 when the levers 11 move. One lever 11 carries a pawl 15 arranged to engage a ratchet wheel and turn the roller 18 at the same speed as the member 9 in order to prevent sliding between the two. Continued movement of the levers 11 carries the roller 10a on the roller 10 along a curved guide 14, causing the lever and member 9 to turn on their axis into position for the member 9 to apply paste to a signature 23 supported on a saddle-shaped member 8.  The member 8 is carried by the lever 5 under the influence of a cam 3 on the shaft 2 serving to swing the member to stitching-position after application of the paste.

Abstract: 1,186,086. Measuring particle size by gammarays. MENCH & MIKSITS RESEARCH & MFG. CO. Inc. May 1, 1967 [May 4, 1966], No.20112/67. Heading G1A. The particle size of dry comminuted solids is determined by depositing the solids in the upper end of a tube containing a plunger moving the plunger downwards at a uniform speed so that the solids are compacted to an extent depending only upon the particle size, and measuring the density of the compacted solids by gamma-ray absorption. Ground cement is separated by an air classifier 10 into coarse and fine solids. A sample of the fine solids is continuously extracted by a screw conveyor 26 and returned to the stream by a screw conveyor 28. A portion of the sample in conveyor 28 passes through a slit in the wall thereof into the tube 106. A plunger 130 is driven down the tube 106 by a chain drive 176 so that the sample of settled solids is passed between a Cs-137 source 102 and an ionisation chamber 104, which measures its density. At the end of the measurement, the plunger is driven upwards at higher speed and the sample is returned to the conveyor 28 through a large aperture which replaces the slit. The result of the measurement may be recorded or used to adjust the classifier 10.

Title: Improvements in or relating to fuel control in internal-combustion turbine engines
Inventor: TURNER HORACE GEORGE
IPC: F02C7/22
Filed: 1960-06-10
Abstract: 980,088. Gas turbine plant. PLESSEY CO. Ltd. June 8, 1961 [June 10, 1960], No. 20427/60. Heading FIG. A fuel control device for gas turbine engines comprises a spool valve axially displaceable within a ported sleeve, means being provided for continuously rotating the sleeve, further means being provided-responsive to at least one operating condition of the engine to cause axial movement of the sleeve upon a predetermined operating condition being reached so as to increase the flow resistance through the valve. In Fig. 1, the fuel metering unit 14 comprises a spool valve, 16 disposed within a sleeve 17 having metering ports 18, the sleeve being disposed within a bore in the valve body 15. A chamber at the upper portion of the valve body is divided into two compartments 24, 25 by means of a diaphragm 26 which is secured to the spool 16, the compartment 24 being connected to compressor delivery pressure through restricted orifice 30 and the compartment 25 being connected to atmosphere through port 28. An orifice interconnecting the compartments 24, 25 is normally closed by a spring-loaded half-ball valve 31, the stem of which slides within a sleeve 33, the axial position of which is set by means of a control lever 36. A head 34 on the stem of the valve 31 can engage the sleeve 33 whereby at certain conditions, the spool valve 16 can move away from the valve 31 so connecting the compartment 24 to compartment 25 and so to atmosphere. The spool valve is loaded upwardly by spring 27 so as to restrict the metering orifice 18. The sleeve 17 is rotated continuously during operation by means of gearing 21 at a speed proportional to engine speed, and the sleeve carries at its lower end a governor device 38 which in operation tends to move the sleeve 17 downwardly against the loading of spring 39. Fuel is supplied to the metering device by means of an engine driven pump 10 and after passing through the metering orifices 18 passes to a burner device 20, a shut off valve 19 being disposed downstream of the metering orifices. The pressure drop across the metering orifices is maintained constant by means of a diaphragm 22 and valve 23, the fuel at pump pressure being connected to the upper side of the diaphragm 22 so as to tend to open the valve 23 which would allow fuel to pass back to the pump inlet, while metered fuel pressure downstream of the orifices 18 is connected to the lower side of the diaphragm 22 and tends to close the valve 23. If the compressor delivery pressure should rise above a valve pre-determined by the setting of the control lever 36, the pressure in the compartment 24 will cause the diaphragm 26 to move the valve seat away from valve 31 and so pressure in the compartment 24 will be vented through compartment 25 to atmosphere and the spool valve 16 will move upwardly under the action of spring 27 to restrict the metering orifices 18.
