Abstract: 350,170. Printing-machines. BARKER, R. W., 56, Ludgate Hill, London. -(American Bank Note Co.; 70, Broad Street, Manhattan, New York, U.S.A.) May 1, 1930, No. 13458. [Class 100 (ii).] Inking-apparatus.-In an inking apparatus for applying very viscous ink, such as that used for printing safety grounds of securities, the ink duct is provided with a number of paddles, pivoted to supports reciprocating longitudinally of the duct, and adapted to force the ink into the space between the duct roller and duct blade. The duct 10, provided with a duct roller 12 and duct blade 11, is formed with bearings 23 to receive a slidable bar 24 to which are adjustably and detachably clamped a number of arms 29 to each of which is detachably clamped a plate 33. A paddle 35 is hinged to the front edge of each plate 33 and has a free pivotal movement limited by stops 37, 38 engaging opposite side of the plate 33. The bar 24 is connected by a link 27 to one arm of a bellcrank lever 25, the other end of which is connected by a link 28 to a second bell-crank lever 20 the arms of which are connected to an operating crank pin 21 and to an oscillating arm 17 carrying a pawl 18 actuating the ratchet wheel 13 of the roller 12. During half a revolution of the crank pin 21 the roller 12 remains stationary and the bar 24 is moved to the right in Fig..3. Owing to the resistance of the ink the paddles 35 first turn about their hinges until arrested by the stop 37 and then press the ink bodily toward the roller 12. During the second half revolution of the crank pin 21, the roller 12 is turned to feed the ink to the ductor roller 14 and the bar 24 is returned to its previous position, the paddles 35 reversing and again forcing the ink toward the roller 12. A distributing roller 15 engages the ductor roller 14.

Abstract: 573,381. Conveyers; feeding hoppers. FOUNDRY EQUIPMENT, Ltd., and BEECH, A. S. Aug. 20, 1943, No. 13612. [Class 78 (i)] [Also in Group XXII] In apparatus for filling containers or hoppers 26 with loose material, e.g., feeding sand to moulding machines, of the type comprising an endless belt conveyer 22 and a deflector 46 in the form of a scraper or plough movable towards and away from the conveyer and arranged in one position to feed the material into the container, the container is movable bodily from a loaded to an unloaded position and connected with the deflector to move it to the feeding position when the container is in its unloaded position. The hopper 26 has a flange 28 supported by springs 32 from girders 16, 17 which support a chute 52 extending adjacent the conveyer belt 22. The scraper comprises side limbs 43, 44, an end limb 45 and a scraper member or plough 46, and the limb 44 is extended to form a counterweighted arm 54 pivoted to fixed brackets 48 and connected by a rod 60 with the hopper. When the hopper is emptied through lower doors 56 operated by a handle 58 it rises under the action of the springs 32 and the scraper is lowered to feed the material. The downward movement of the fully-loaded hopper raises the scraper and stops the feed. The scraper may be locked in its inoperative position by a pin passed through holes 68 in the arm 54 and a fixed bracket 66. Specification 12186/10, [Class 78 (i)], is referred to.
Patent GB-272335-A (GB)
Title: Improvements in and relating to electric telegraphy
IPC: H04L12/12
Filed: 1926-05-29
Abstract: 272,335. Jacob, W. G. R., and Eastern Telegraph Co., Ltd. May 29, 1926. Electric synchronous movements; code telegraphy; paper feed for receivers, automatically controlling; type-printing telegraphs.-In a system employing direct-current impulses, in which synchronism is maintained by the message signals, the receiving perforator, type-printer, or other recorder, which is temporarily thrown out of action by the receiving operator on receipt of a special series of signals transmitted during a pause, is automatically restarted after the pause by modifying such special series of signals. The latter may serve to maintain the synchronism during the pause. The dot and dash line ralays a, b, Fig. 1, energize from a battery e the dot and dash selector relays c, d respectively, the circuit in each case including a switch f normally closed by a spring g. During a pause in signalling the transmitter sends one dot for every ten centre holes of the tape, whereupon the receiving operator opens the switch f to throw the receiving instrument out of action, and the switch is held open by a latch h on the armature of a magnet j. The line relays a, b also energize from the battery e the left- and right-hand windings respectively of a relay k. The front contact of this relay is connected through a resistance n to one pole of the battery e, the back contact is conected through the magnet to one plate of a condenser m which is connected to the other pole of the battery, and the armature is connected to the other plate of the condenser. The condenser is thus charged from the battery upon receipt of a dot or a dash signal, and is subsequently discharged through the magnet j. The value of the resistance n is such that the charge accumulated by the condenser in respect of a single dot or dash signal is insufficient to trip the latch h when discharged through the magnet j. Upon resumption of the message signals after the pause, however, the charge accumulated in respect of the first signal containing two marking impulses is sufficient to trip the latch, thus closing the switch f and bringing the receiving instrument again into operation. In a modification, Fig. 2, the switch f is replaced by the armature of a relay o of which the left-hand winding corresponds to the winding of the magnet j, Fig. 1, and the righthand winding is in circuit with the battery e through a switch p and a resistance q. The switch p is opened by the receiving operator upon receipt of the special signals, and recloses when released. The opening of the switch de-energizes the relay o whereupon the relay armature opens the circuits of the relays c, d at the two front contacts and short circuits the switch p at the back contact. Upon resumption of the message signals the relay o is energized sufficiently to reclose the circuits of the magnets c, d as in the arrangement of Fig. 1. Specification 240,906 is referred to.

Abstract: 1337838 Hydraulic motor control circuit CATERPILLAR TRACTOR CO 10 May 1971 [3 June 1970] 14047/71 Heading F1P A control circuit for a reversible hydraulic motor 11 comprising an inlet valve 19 which connects either a low or high capacity pump 14, 14' to the inlet 36 of a valve body 32 having spaced apart forward and reverse passages 46, 47 connected to opposite sides 12, 13 of the motor 11 and each passage is provided with a first check valve 42, 39 and with a second check valve 43, 41 by which the associated passage 46, 47 may be connected to a drain 16' and the circuit also includes a two-position direction controlling valve 48 which when in the forward position shown connects the outlet of valve 19 by means of a check valve 49 and a honed spool 54 and a branched duct 52 with the rear of check valves 39, 43 which are thus held on their seats 38 and the valve spool 54 when lifted by a compressed air actuated piston 59 to its reverse position connects the outlet of valve 19 through a branched duct 51 to the rear of check valves 42, 41 which are thus held on their seats 38. In operation and with valve 19 moved to either slow or fast position and with valve spool 54 in the position shown check valve 42 is free to open against its spring 44 to admit fluid through passage 46 to the forward side 12 of motor 11 whilst check valve 41 is free to open to connect the motor exhaust through a drain port 37. In the event of the forward moving motor being driven by the load the resulting pressure reduction in passage 46 is transmitted through orifices 68 in valve 43 which is then opened by the increased motor exhaust pressure thereby by-passing a portion of the motor exhaust to the motor inlet. Check valve 41 has similar orifices 68' so that fluid is by-passed during the reverse motion of motor 11 with valve spool 54 in the raised position. Prevention of reversal of motor 11 due to an increase in the driven load which would result in a pressure rise in passage 46 thus tending to open valves 43, 42 is effected by closure of valve 49 which thus provides a lock for valve 43 and by the strength of spring 44 of valve 42 which is held closed. Valve 19 is manually operated and is mechanically linked to an airvalve 83 for controlling piston 59.
