An offset lithographic printing machine comprises a main cylinder 1 having a peripheral segment carrying a printing master sheet 2 and a peripheral segment provided with grippers 4 for holding a copy sheet 5 to be printed, an offset roller 18 provided with a fixed apron 24 or other transfer means on one peripheral segment and a peripherally movable apron 25 on another segment, means being provided for transporting the apron 25 into and out of the interior of the roller 18 in a line-wise or section-wise manner whereby to effect the said peripheral movement and to enable selected parts of the image on the apron 25 to be printed, and electromechanical or mechanical means for controlling co-operation of the roller 18 with the cylinder 1 so that after engagement of the roller with the cylinder for transfer of the text of the master 2 on to both aprons, on each successive revolution of the cylinder the roller cooperates with the sheet 2 or by means of the apron 24 whereas the offset roller cooperates with the sheet 5 on each successive rotation of the cylinder by means of the apron 24 and also by a selected part of the apron 25. The apron 25 is unreeled from the shaft 26 and wound up on the shaft 47. The shaft 19 of the roller 18 is mounted between a pair of angular levers 48 which are pivoted at 49 and swinging of the roller 18 is controlled by energization of electromagnets 52, the armatures 51 of which are connected to said levers. Mechanical means such as cams or eccentrics may alternatively be used. The apparatus is controlled electrically by a switching arm 56 which rotates in synchronism with the cylinder 1. Initial energization of the electromagnets 52 swings the roller 18 against the cylinder 1 and the heading portion of the image is received on the apron 24 and the rest of the image on the apron 25. When the arm 56 reaches contact 72, Fig. 1, the roller co-operates with the cylinder 1 to print the heading from the apron 24 and on reaching contacts 74 and 75 the roller co-operates with the cylinder to print the first two lines from the apron 25, assuming the corresponding keys on a switchboard, Fig. 4, not shown, have been pressed. When the arm 56 reaches the contact 80 the heading is transferred to the fixed rubber apron 24. The said switches also cause electromagnets to introduce cam members 42 1  and 42 2  into the path of a pawl 37, Fig. 2, and the apron 25 is moved by an amount equal to two lines of text by means including pawls 34 and 37, a transport wheel 31 and a torsion spring 32. On subsequent rotation of the arm 56 the heading and then lines three and four of the text are printed. Both aprons are cleaned by a washing device 81, 82, 83 and 84.

Abstract: 1,259,667. Calendar timepieces. EBAUCHES S.A. Aug.29, 1969 [Aug.30, 1968], No.43249/69. Heading G3T. A calendar timepiece comprises a setting stem 27 able to occupy three different axial positions namely on inoperative rest position; a time setting position and a date setting position. A lever 28, pivoted at 29 and biased in a clockwise direction by a spring 30, supports a gear-wheel 33 and a date setting wheel 32. A neck portion 28b of the lever engages a groove 36 in a pinion 34 slidable along a portion 27a of square section of the stem 27 and a second lever 37, pivoted at 38, has a projection 37a which engages a groove 40 in the stem. A spring detent 39 defines three positions for the lever 37. The pinion 34 meshes with the gear 33 which, in the rest position shown, does not mesh with any other gear. When the stem is pulled outwardly the lever 37 pivots in a clockwise direction and rotates the lever 28 in an anti-clockwise direction, thus causing the gear-wheel 33 to mesh with a pinion 13. Rotation of the stem in this position enables the hands to be set and a pin 42 on the lever 28 operates an electric contact to break the oscillation maintaining circuit of the timepiece driving mechanism. When the stem 27 is pushed in to an intermediate position the star wheel 32 meshes with the toothing 26 of a date indicating crown 25 to enable adjustment of the date. Reference has been directed by the Comptroller to Specification 1, 168, 745.

Abstract: 1,072,944. Tunnel - diode logic circuits. ENGLISH ELECTRIC-LEO MARCONI COMPUTERS Ltd. Dec. 12, 1963 [Dec. 28, 1962], No. 43295/62. Heading H3T. An electrical signal transfer and storage means comprises a transformer having primary windings 19, 20, 21 each of which is connected in series with a respective unidirectional diode between respective pairs of terminals, input electric signals (of either zero or -2 volts) being applied to terminals 10, 11, 12 and negativegoing control pulses being applied to terminals 13, 14, 15, and a secondary winding 26 which is so coupled to a tunnel diode 31 biased through resistor 33 to a bi-stable condition that when current flows in the secondary winding 26 on the application of a control pulse to an appropriate one of the terminals 13, 14, 15, the tunnel diode is switched to its high voltage state and a corresponding output is delivered to terminal 42. In the circuit illustrated the application of a negative-going control pulse at one of the terminals 13, 14, 15 results in the establishment at terminal 42 of an output voltage equal to the input voltage (of either 0 or - 2 volts) at the corresponding one of terminals 10, 11, 12. Terminals 13, 14, 15 are normally at + 1 volt; a negative-going pulse of 2 volts amplitude causes current to flow in the primary winding 19, 20 or 21 if the corresponding input terminal 10, 11 or 12 is at zero volts but not if it is at - 2 volts. When tunnel diode 31 is triggered to its high voltage state, transistor 37 conducts and delivers a zero-volt output; otherwise the output at 42 remains at - 2 volts. Transistors 35 and 37 may be omitted; if transistor 35 is omitted a rectifier diode should be connected between the transformer secondary and tunnel diode to prevent reverse current flow when the initiating pulse ceases.

Abstract: 1,148,355. Automatic voltage control. GENERAL MOTORS CORP. Sept.28, 1967 [Oct.7, 1966], No.44111/67. Heading G3R. A voltage regulation circuit for an alternator includes a device connected so that it operates to short circuit the alternator output coils when the alternator output voltage exceeds a predetermined value. As shown, a three-phase alternator of the permanent magnet type has output coils 6, 7, 8 which are connected to D. C. output terminals 20, 21 by way of a full-wave rectifier. A voltage sensing circuit is connected over a transistor 70 across the terminals 20, 21 and produces a control signal when the output voltage exceeds a predetermined maximum value, the circuit comprising a voltage divider 50, 51, 53, a Zener diode 65 and a transistor 60 at the collector of which the control signal appears. The base of transistor 70 is connected over diodes 76, 77, 78 to the output windings 6, 7, 8 so that the transistor 70 is rendered conductive to energize the voltage sensing circuit only when the alternator produces an output, and the collector of transistor 60 is connected by way of equalizing resistors 66, 67, 68 to the control gates of thyristors 46, 47, 48.which when conductive, short-circuit the output windings 6, 7, 8. The thyristors are rendered conductive by the control signal only when the output voltage exceeds the predetermined value; the resulting heavy current flow through the output coils produces a high potential drop, thereby reducing the system potential which thus tends to remain constant at the predetermined value. The system may include a battery 24 connected across the output terminals, and an indicating lamp 80 associated with a switch 81.

Abstract: 956,153. Battery charging systems; electrically released switches. ACCUMULATORENFABRIK SONNENSCHEIN G.m.b.H. Dec. 22, 1960, No. 44136/60. Headings H2B and H2H. A rectifying semi-conductor element 2 such as a Zener diode having a non-linear voltage/ resistance characteristic has a heat-sensitive material 3 mounted in heat-exchange relationship with the element 2 which heats up at a predetermined voltage and causes the element 2 to initiate a switching and/or signalling step. A small permanent magnet 4 previously attracted to the material 3 through polepieces 5 against the pull of a spring 7, is released when the element 2 heats up and causes the material 3 to reach its Curie point so that the spring 7 pushes a knob 6 out of the casing 8 and parts a pair of switch contacts 10 by means of a non-conducting blade which may be also so shaped that a second pair of contacts can be additionally interrupted after a short time delay. The movement of the knob 6 serves as an indication that the switch has operated and it can be reset by depressing the knob 6 after the material 3 has again become magnetic. The switch may alternatively be actuated by a bi-metallic strip or by a heatdependent expandable fluid. In a battery-charging and loading circuit shown in Fig. 3, the heat evolved by a Zener diode 16 when a battery 12 is fully charged, opens contacts 14, 14a and limits the charging current from the source U by a resistor 23. When the battery is loaded, switch 15 is put into position B so that diode 16 may constitute an active component in the load circuit. A semi-conductor 27 such as a tunnel diode, is arranged to draw little current when the battery is charged, but when this has been discharged and its voltage drops, the diode 27 draws a current ensuring sufficient heat to open the contacts 29. A thermally-controlled switch 19 prevents the diode 16 energizing heat and hence interrupting the switch 14, when the battery 12 is in the discharged state.
