Title: Printing apparatus
IPC: B41J19/20
Filed: 1969-10-28
Abstract: 1283556 Typewriters INTERNATIONAL BUSINESS MACHINES CORP 28 Oct 1969 [8 Nov 1968 (2)] 52673/69 Heading B6F A typewriter includes printing means and a print medium support member both of which are movable with respect to a frame in order to permit the printing of a line of print longer than the length of travel of the printing means. In a first embodiment, Figs. 2a, 2b, 2c, 2d and 3, a platen 14 has two positions relative to a frame 11, the printing means such as a print head 13 on a carrier 20, first traversing one half of the platen as in Figs. 2a, 26 and then traversing the second half of the platen as in Figs. 2c, 2d. The print head carrier 20 initially steps along the first half of the print line under a single-pawl escapement mechanism 50-53, Fig. 3, until it strikes a latch (101, Fig. 6) whereby a clutch (114) is engaged and a sector 34, Fig. 3, engaging through a gear 32 a rack 31 on the platen carriage is rotated 90 degrees by a crank disc 39. The carriage is thus transferred to its alternative position and typing can continue along the print line. During transfer of the carriage so character may be printed but a character corresponding to a key depressed during the transfer is stored and automatically printed when the transfer is completed. On depression of a carrier return key (79, Fig. 7) the carrier 20 and platen carriage are returned under power to the position shown in Fig. 2a, and the platen is indexed for line spacing by mechanism 70, Fig. 3. At the end of a print line, the keyboard is locked by a member 92 entering a key interlock 93 owing to depression of a bail 87 by a margin stop (85, Fig. 6). Tabulation mechanism.-Tabulation stops 60 are held in a slotted tube 61 mounted on the platen carriage 28, the stops being set and cleared by rotation of the tube 61 and interaction of the stop 60 with a setting projection 62 or a projection 63 of the stop with a clearing projection 64. In an alternative embodiment, Fig. 8, a print head carrier 221 is coupled to a platen carriage 231 by a pulley 235 mounted on the platen carriage 231 and a cable 240 connected between the print head carrier 221 and the frame 211. Thus for each stop to the left of the carriage 231 under drive of a clock spring 251 opposed by escapement mechanism 281-287 on the print head carrier 221, the print head carrier 221 makes a step to the right of twice the magnitude. Powered carrier and carriage return is initiated by engaging a clutch 256 whereby a cable 270 connected to the carrier 221 is wound on to a drum 259. The printing means may be a spherical head as shown or a tyre lever mechanism or a wire printing element.

Title: Control systems
IPC: G05D1/08
Filed: 1971-11-17
Abstract: 1413791 Automatic control systems ROLLSROYCE (1971) Ltd 8 Nov 1972 [17 Nov 1971] 53335/71 Heading G3R A closed loop control system has a first mode of operation which has fast response and a second mode which has a damped response, change over being effected by switching means in dependence on a predetermined ratio between the error and the rate of change of error, or between the error and the rate of change of the output, or between the error and a linear combination of the rates of change of the error and the output. The object is to achieve very rapid response to an error and to provide a damping term only when necessary to prevent overshoot. The system may be applied to control roll, pitch or yaw in a VTOL aircraft, in which case air bled from the engine is exhausted through downwardly directed nozzles, e.g. on the wingtips, the area of the nozzles adjusted differentially by the invention. Such a system is said to be a "double integrater plant" shown at 8 in Fig. 4. 7 is an electrohydraulic actuator. An input signal 30 is compared with the output 31 at summing amplifier 1. Circles such as 33 denote "gain adjusters". The resulting error signal is supplied to a further summing amplifier 6, whose output controls the actuator 7; these constitutes are mode and it has very rapid response. A damping term is added at 6 when switch 4 is closed to provide the second mode. As shown this is provided by integrating the control signal at 5; since the plant has "double integration", this is equivalent to the first derivative of the plant output, and such a signal may alternatively be provided by differentiating the output signal. The switch is controlled by a logic network 3 comprising the AND and OR gates 46, 48. Comparators 44, 45 determine the sign of their inputs and pass signals accordingly to AND 46 if positive and to AND 47 if negative. The switch is opened if the inputs to the comparators are of opposite signs. The input to 44 is the damping signal while that to 45 is the sum of the damping signal (i.e. the first differential of the plant output), the input to the plant from 6 which is equal to the error signal when switch 4 is open, and the first differential of the error which is obtained by the elements 35, 36 and 38 ... 40. The summation is performed in amplifier 37 and the gain of the various devices is chosen so that the sign of the output of 37 changes (as it goes through zero) when the ratio of the error signal to the other inputs to 37 has the prescribed value. It is said that the devices may be digital or analogue and either mode may be linear only between prescribed limits.

Title: Blanking press

Filed: 1973-11-19
Abstract: 1406397 Punching INTERNATIONAL BUSINESS MACHINES CORP 19 Nov 1973 [22 Dec 1972] 53562/73 Heading B3W For fine blanking, an auxiliary punch and die 6, 15 coact to punch partly through the thickness of a workpiece from one side, above as shown, and a main punch and die 19, 3 then coact to completely punch through the workpiece from the other side. The main punch 19 is resiliently coupled by a spring 29 to a slide 24 driven by a motor via a toggle mechanism (neither shown). The auxiliary die 15, surrounding the punch 19, and its supports 13, 14 are supported by a hydraulic cylinder 18. The auxiliary punch 6 is driven by a hydraulic cylinder 11 and the main die 3 surrounding it is supported by a fixed mount 1. In operation, with the auxiliary punch 6 projecting slightly from main die 3, Fig. 1, the slide 24 raises the auxiliary die 15 and the workpiece resting on it against the auxiliary punch 6 and die 3, the punch causing the workpiece material to enter the aperture 17 of the die 15 and the punch 19 receding and compressing the springs 29. The material is clamped between the dies 3 and 15. As the slide 24 is raised further, the main punch 19 is raised with it and coacts with the main die 3 to punch out a blank, the auxiliary punch 6 receding against the action of hydraulic ram 12. When the surface of the main punch 19 is flush with the face 4 of the die 3 the motion of the slide 24 is reversed. To strip the workpiece from the die 3, the pressure in cylinders 11 and 18 is momentarily interrupted. Pressure is restored during descent of the punch, to cylinder 18 first and then to cylinder 11 which replaces the blank in the workpiece which is then moved out of the dies to a station where the blank is pneumatically ejected.

Abstract: 1,206,146. Labelling machine. LITTON BUSINESS SYSTEMS Inc. 29 Nov., 1967 [29 Nov., 1966], No. 54397/67. Heading B8F. Labels 28 (Fig. 1) detached from a backing strip 26 when this is passed over a sharp edge 32 are applied to articles 36 by means, such as a hammer 406, operated in timed relationship with motor-driven means for feeding the strip. In the form illustrated the strip is fed by a pin drum 330 driven through a constant-stroke ratchet mechanism from a barrel cam 222 and the hammer 406 is operated by a solenoid 432 controlled through a switch from a cam on the shaft 90. The shaft 90 is driven from a shaft 70 (Fig. 4) through a roller 76 engaging a roller 86 on the shaft 90. Once the roller 76 is moved to the driving position of Fig. 4, by a starting solenoid it is held in this position until a cam 198 on the shaft 90 permits a follower 136 to return the roller 76 to disengaged position and simultaneously to apply a brake 146 to the drum 86. The starting solenoid is operated through a hand- or foot-controlled switch, according to the setting of a selector switch, and can be operated only when a lever 442 (Fig. 1) detects the presence of an article 36. The label strip is held down on the surface 382 (Fig. 1) by a blade spring 384. The drum 320 may be replaced with other drums of different radii and pin-spacing. The strip is held on the drum by a pivoted shield 336 and is stripped from it by a blade 344 engaging in a groove on the drum. The labels may overlie the sprocket holes in the strip or these may be disposed between the labels or on either side of them. The labels may be spaced or in contact on the strip. Each label in turn is printed by mechanism 30.
