IPC: B41L39/04
Abstract: 1,053,552. Duplicating machines. BLOCK & ANDERSON Ltd. July 25, 1963 [April 25, 1962], No. 15783/62. Heading B6C. In a rotary hectographic duplicating machine comprising a printing cylinder 10, an impression cylinder 12, a pad 31 for dampening the copy sheets, and rollers 15, 16 for feeding single sheets from a table 14, manual control means are provided whereby at the end of a revolution of the printing cylinder the rollers 15, 16 are either in contact for registering the front edge of the sheet against the bite of the rollers, or the rollers are separated so that the front edge of the sheet can be passed up to or beyond the bite of the cylinders 10, 12. The latter arrangement is required if the printing on the sheet is to be considerably displaced from its leading edge; in this case, register of the sheet may be effected by a back stop 53. The roller 16 and the pad 31 are carried by levers 17 and 32 respectively, spring-biased towards the operative positions. Pins 21, 36 on the levers can be engaged by latching recesses 22, 37 in spring- biased levers 23, 38 respectively to hold the roller 16 and pad 31 in raised position. Links 47, 49 connect the levers 38, 23 to a lever 44 pivoted at 45 and connected to the armature of an electromagnet 42. The latch lever 23 has an upward extension 27 engaged by a nose 28 on a manually-set lever 29. With the lever 29 in the chain-line position shown, the latchlever 23 is held permanently in inoperative position so that rollers 15, 16 are engaged, the other parts 49, 47, 44, 38 of the mechanism being unaffected because of a lost-motion connection 26, 50, 51 between the link 49 and the lever 23. If, after a sheet has been placed on the table 14 with its front edge at the bite of rollers 15, 16, a starting switch 57 is operated, the cylinder 10 is driven through a one-revolution clutch, the roller 15 is driven, and a cam member 40 is driven in synchronism with the cylinder 10. At the same time energization of magnet 42 operates lever 44 to cause latchlever 38 to be moved to free lever 32 so that pad 31 drops on to the sheet. Printing now takes place and, near the end of one revolution, the cam part 40a engages a follower 20 on lever 17 to lift the roller 16 momentarily and similarly engages a follower 35 on lever 32 to lift the pad 31 which is relatched in the raised position. With the hand-lever 29 in the position shown in full line, the latching lever 23 is operated similarly to the lever 38 so that roller 16 is latched in raised position at the end of a revolution of cylinder 10 and released at the beginning of a revolution. Selective line-printing may be effected by the provision of a number of line-width axiallyarranged segments radially movable on the cylinder 10 as described in Specifications 882,914, 900,117 and 907,212.

Abstract: 1,058,099. Controlling burners. FENWAL Inc. May 26, 1965 [April 1, 1965], No. 22294/65. Heading F4T. A system for igniting a burner and monitoring the flame thereof comprises a pair of spark electrodes 26, 28 energized by a transformer 46 and a diode bridge circuit 52, 58 in series with the electrodes and adapted to energize a relay 62 or a silicon controlled rectifier 66, Fig. 3, not shown, controlling a valve 18 supplying fuel to the burner. The transformer has a tapped primary winding and at starting a part only of the primary winding is energized to provide a high secondary voltage sufficient to cause sparking at the electrodes and to open the fuel valve. A thermal relay 42 energizes a relay 80 controlling contacts 80c after a predetermined time to energize the whole of the primary winding of the transformer to produce a reduced secondary voltage which, in the presence of a burner flame, provides sufficient current to keep the fuel valve open. The voltage across the primary of the transformer is rectified by a diode 88 and applied to a relay 92 in series with a Zener diode 94. The relay 92 also controls the fuel valve 18. A resistance 84 is included in the primary circuit of the transformer and consequently if the spark electrodes are shorted a low impedance is reflected into the primary winding of the transformer and the relay 92 therefore drops out to close the fuel valve. In a simplified circuit, Figs. 1, 2, 3 (not shown), the relays 80, 92 are omitted. In another circuit, Fig. 5 (not shown), there is no reduction of voltage after ignition.

Abstract: 1,226,111. Valves. SOC. ANON. FRANCAISE DU FERODO. 8 April, 1968 [20 April, 1967], No. 16886/68. Heading F2V. [Also in Divisions F4 and G2-G3] A vacuum regulator for use in a vehicle airconditioning system comprises a self-lapping valve in which a diaphragm 49 co-operates with the top of a tubular valve member 28 to control communication between inlet and outlet chambers 22, 101 via the bore 31. The outlet vacuum seats the diaphragm against the action of leaf spring 82. Member 28 also co-operates with ring 37 to control communication between outlet chamber 101 and atmospheric chamber 26. A unitary or composite ring 25 biases member 28 upwards. The outlet pressure is adjusted by rotating cam 61 to vary the load exerted by spring 82. Calibration of the latter is effected by screw 93. The spring 82 may be of thermally responsive bi-metal construction or screw 93 may be replaced by a thermal element. In Fig. 6, a bi-metal spring 102 is adjusted by diaphragm 50<SP>1</SP> which responds to a pressure in 130 as determined by a remote valve of the Fig. 2 construction. The spring pivots at 127 to control a further regulator 10. In an exemplary system (Fig. 7, not shown), a manually-controlled regulator (203) as in Fig. 2 controls a jack to vary the air flow across a radiator (212). The air temperature is sensed by the bi-metal spring of a regulator (R, C) as in Fig. 4, and the latter controls the water flow through the radiator. Regulator (R, C) is controlled by a regulator (208) similar to (203).

Abstract: 1,226,453. Universal timepieces. BULOVA WATCH CO. Inc. Oct. 29, 1968 [Nov. 14, 1967], No.51317/68. Heading G3T. A timepiece comprises a minute hand shaft 30 coupled to an hour hand LT by a differential gear system 26-29 to permit incremental movement of the hour hand in either direction by means of an intermittent motion device which moves the hand in 30 degree increments. A hand GT, which is rotated by the timepiece drive motor at one revolution in 24 hours, is set to Greenwich mean time on a fixed 24 hour dial 11 by rotating a crown A, the minute hand M also being set. The hand LT also moves, however its position is adjusted to indicate the correct local time by rotating a crown B. The rotation of the crown B advances or retards the hand LT by 30 degrees or one hour increments and is rotated a full turn each time a new time zone is entered. The adjustment of the hand LT does not affect the indication of the hands GT or M which continue to indicate correct Greenwich mean time. Before rotating the crown A it is pulled out to disengage the timepiece drive motor, which may be a tuning fork, from a cannon pinion 13 and to couple the crown to a minute wheel 16. Rotation of the crown A thus rotates the hand LT through a gear 17, a sun gear 26, planet gears 27 and a carrier 28, a ring gear 29 being fixed in position at this instant. The wheel 17 also rotates the hand GT via gears 21-24. To set the hand LT, which is rotated via the sun gear 26, &c. at one revolution in 12 hours, without altering the setting of the hand GT, the crown B is rotated to rotate a squared shaft 41 via a gear assembly 37, 38, 42. The gears 37, 38 are linked by slots and pins 37A, 38A; 37B, 38B. The shaft 41 rotates an index cam 39 of the intermittent motion device, the cam rotating a Geneva gear 32 via a pin and slot drive 39a, 32a. The gear 32 is rotated abruptly to index the ring gear 29 by a spring 40. The rotation of the ring provides a 30 degree movement of the hand LT via the planet gears 27 and the carrier 28.
