Title: Tension control for rotary press
IPC: B65H23/188
Filed: 1972-12-05
Abstract: 1370708 Web-fed multicolour offset press WOOD INDUSTRIES Inc 5 Dec 1972 [17 Jan 1972] 56025/72 Heading B8R In a web-fed multicolour rotary offset press the web on its first pass through the printing units is printed on one side and also furnished with register marks such that in the second, and, if necessary, subsequent passes through the press, further printing is accomplished in register with that of the first pass. During the first pass in the press of Fig. 1 the web is printed whilst in a predetermined basic tension. In the second pass this tension is lessened to a lower basic value and the difference between the two basic values is used to ensure that correct register is obtained in printing. To this end, the web feed roller 24 is driven from the main press drive 42 through a manually settable variable drive 44 and the final pulling off roller (not shown) of the press is driven at a fixed speed. A photoelectric monitoring device 80 detects the register mark and provides pulses corresponding thereto and a phase micrometer 82 provides reference pulses. Both sets of pulses are fed to a computer control box 84, Fig. 4, and any error signal is transmitted to a servo-motor 64 which actuates a differential 58 in the drive line between the variable drive 48 and the web feed roller 24. Such actuation either accelerates or retards the speed of the roller 24 and thus effects a change in web tension.

Abstract: 1281007 Fish feeder J A HENRIKSEN 1 Dec 1969 [3 Dec 1968] 57282/68 Heading A1A [Also in Division F2] In a device for feeding fish, the food is blown out over the water by compressed air. Food tank 4 supplies food to dose chamber 6. Air chamber 12 is connected to pipe 10 via valve 16. On opening valve 16 air passes through pipe 10 and blows the food out through pipe 8. The valve is designed so that the air passes through pipe 10 comparatively slowly at first, but with increasing speed, so that the food is blown out over a period of time and spread over a wide area. The operation of the device is controlled by a clock 20 which operates valves 24 and 26. When valve 26 is opened compressed air is supplied to valve 16 causing it to open, simultaneously valve 24 is closed, stopping further supply of air to air tank 12. After a preset time valve 26 is closed and valve 24 is opened causing the valve 16 to close and the air pressure in the air tank to build up. A manually operated valve 30, Fig. 2, and a non-return valve 32 are mounted on the air tank. The valve operates by air entering 64 from the control line 18, causing diaphragm 60 to rise, which in turn lifts the valve member 42 off valve seat 35.

Title: Improvements in or relating to a control mechanism for controlling an adjustable speed regulator of a combustion engine
IPC: F02D11/02
Filed: 1969-12-23
Abstract: 1284597 Controlling motor vehicles INTERNATIONAL HARVESTER CO 23 Dec 1969 [23 Dec 1968] 62564/69 Heading B7H [Also in Division F1] A motor vehicle includes an internal combustion engine and a control mechanism for controlling a speed regulator of the engine, the mechanism including a lever assembly 50 connected to the regulator for controlling the speed of the engine, first control means 32 by which the lever assembly 50 is actuable to preset a first engine speed and second control means 21, by which the lever assembly is actuable to control the speed of the engine at speeds in excess of the preset first speed, the second control means including a counterweight 23 which initiates alteration of the setting of the first control means as the second control means is released from an actuated position. As shown, the lever assembly 50 includes a plate 51 pivoted at 52 and connected to the speed regulator control rod 13. A hand lever 32, mounted to the dashboard 11 through friction pads 34, is fast with a rotatable rod 31 connected to a push-rod 39 which comprises a resilient part 42 and a semi-spherical end portion 41 co-operable with an abutment on the plate 51. Rotation of the hand lever 32 in the clockwise direction (as seen from above), causes the plate 51, and hence the rod 13, to move generally clockwise of pivot 52. By this means, a first slow-running engine speed is preset. A footpedal 21 supporting a counterweight 23 is connected to a rod 24 pivoted in a plate 55, the end of rod 24 adjacent this plate carrying a member 56 which is co-operable with a portion of plate 51. By this means, depression of the foot-pedal 21 causes member 56 to act on plate 51 to pivot the same clockwise about pivot 52 whereby the engine speed is increased. Relaxation of force depressing the pedal 21 allows plate 51 to return to its position determined by the setting previously set by means of the hand lever 32. The inertia of the counterweight 23 and the shockabsorbing characteristics of the resilient part 42 prevent the setting of the hand lever being altered unintentionally as plate 51 pivots towards its normal position and contacts the end portion 41 upon release of the foot-pedal. Also provided is an over-centre mechanism 70 comprising an arcuate member pivoted to plate 51 at 71 and connected by spring 73 to a frame member 74. At positions of plate 51 corresponding to low engine speeds, the line of action of the spring force is to the right of pivot 52 so that the plate 51 is urged towards a lower-speed position; at positions of plate 51 corresponding to fast engine speeds, the line of action of the spring force is to the left of pivot 52 so that the plate 51 is urged towards a faster-speed position.
Patent GB-691524-A (GB)
Abstract: 691,524. Automatic control systems for aircraft. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Jan. 26, 1949 [Jan. 26, 1948], No. 2154/49. Class 38 (iv). Two or three dimensional control of a craft is effected so as to maintain it in a given channel or zone; upon deviation of the craft from a channel it is given a predetermined compass heading to return it to the channel. As shown, Fig. 2, the craft is to be maintained within the channel D<SP>1</SP>, D<SP>2</SP> and for a given x co-ordinate, xr, known directionfinding means in the craft produce an error voltage corresponding to the distance yr-yi, i.e. the distance between the desired position on course D and the actual position N. This error voltage is applied at 14, 15, Fig. 4, and in accordance with its sign, one or other of relays 22, 23 is operated and one of the contacts 25, 26, 27 is connected to battery 24 according as the craft is to the left, right or inside the channel D<SP>1</SP>, D<SP>2</SP>. Arm 29 is rotated by motor 30 until it reaches the contact connected to 24 whereon relay 33 stops motor 30 and energizes the bridge 35, 36, 39, 40 from battery 37. The arm 36 is fixed in space, e.g. by a compass, while resistance 35 is rigidly attached to 29 and the voltage developed at 41, 42 between 36, 40 is used to position the aircraft controlling surface. As the craft turns, arm 36 remains fixed in space but resistor 35 turns with the craft until the voltage at 41, 42 is zero and the control surface is returned to its neutral setting. In a second embodiment, Fig. 6, the potentiometers 12, 47 are set in accordance with the co-ordinate positions of the aircraft and, as previously, one or other of relays 22, 23 is operated and the terminal 41 connected to one of the points 25, 26, 27 according to the craft position. The secondary windings of transformers 55, 56 produce voltages, which correspond to the firsttime derivative of the co-ordinates of the craft position, and which are opposed, to give at 41, 42 a control voltage for application to the control surface which is zero when the craft is on the correct heading. The signals derived from the direction finder may be applied either to potentiometer or photo-electric devices (not shown) to produce a voltage corresponding to the required path. The invention can be applied both to three-dimensional control and to control in accordance with a time schedule.
