Title: Automatic setting for photocompositing machine
IPC: B41B17/02
Filed: 1971-08-11
Abstract: 1327685 Photographic type - composing VARITYPER CORP 11 Aug 1971 [13 Aug 1970] 37739/71 Heading B6W A photographic type-composing machine comprises a light source 16, Fig. 1, an adjustable light opening 20, Figs. 1 and 2, and a plurality of matrix discs 14 a selected one of which is removably mounted on a turntable 12 by rotation of which a released character is positioned between the opening 20 and a film strip 68. When a selected disc is positioned on the table, slots 94 in the disc pass over knobs 74 on the table, the knobs being shaped so as to be rotated as the disc descends and spring-urged to move back into a locking position when the disc is positioned. A selector slot 92 in the disc engages over a stepped portion 54 of a pin 46 axially movable through an opening in the table, and according to the length of the slot 92 and thus which step of the portion 54 is engaged by the disc surface round the slot, the pin 46 is depressed a predetermined amount against a spring 72 so as to rotate a shaft 36. The shaft 36 causes a cam 34 which, through a rod 27, moves a shutter 24 to adjust the width of the slot according to the size of the character areas on the disc. The rod also causes a cam 58 which, in the case of a disc carrying only half a font owing to the great width of the characters, actuates a switch 62 which sets a drive mechanism 64 for double-sized film linewise movement. In operation, after selection of a character, a switch 23 is moved to "print" position, which energizes the light source 16 and thereafter or therebefore actuates the mechanism 64 to advance the film a normal or double increment according to the setting of the cam 58. The switch 23 can also be moved to a "space" position, in which case the light source is not energized.

Title: Improvements in or relating to a process of and apparatus for producing asphalt
IPC: C10C3/04
Filed: 1930-12-17
Abstract: In a process for oxidizing petroleum residues to produce asphalt, a continuously descending column of the residue is treated with a stream of an oxidizing gas in counter current.  The treatment is preferably effected in a tall tower in which the point at which gas is injected is spaced from the bottom of the tower.  Petroleum residuum heated to a temperature of from 300-550 DEG  F., or directly from a still, passes through a pipe 10, Fig. 1, at the top of a tower 11 through which it descends and is treated with a rising stream of air or oxygen injected through a pipe 16 and a diffuser.  Volatile vapours pass out through a vent 31, and the resulting asphalt passes to the bottom of the tower where, after separating entrained gases, it passes through a pipe 25 to a tank 30.  Baffles 15 may be mounted in the tower.  A pipe 29 is mounted parallel with the tube 25 and is joined to it through cocks 26, 27, 28, whereby the height of the column of residuum in the tower is regulated.  The tower may be heated by an electric coil or a gas burner 19a, in the jacket 14. The upper part <PICT:0361158/III/1> of the tower may be filled with steam admitted through a pipe 20 to avoid risk of explosion.  During the oxidation small amounts of water are formed which causes the residuum to foam and is said to effect better distribution of the oxidizing gas.  The asphalt so made may be submitted to further oxidation in a second tower.

OF GREAT BRITAIN, Ltd., 259, City Road, London.-(International Harvester Co.; 606, South Michigan Avenue, Chicago, U.S.A.) Dec. 17, 1930, No. 38104. [Classes 6 (iii) and 58.] The harvester part, including a platform 10 and cutting mechanism, is carried by pivoted members 45, 46 on a support 8 attached by a bracket 7, horizontal pivot 6 and vertical pivot 5 to an extension 4 projecting from the main axle 3 of the machine. The outer end of the support 8 carries a bracket 11 projecting forwardly and outwardly to which is pivoted the yoke 14 of an arm 15 provided with lugs 23 carrying the pivot pin 31 of a wheel spindle bracket 29. The arm 15 can be latched to the bracket 11 so that the wheel spindle bracket 29 is approximately in line with the support 8, so that the grain wheel 28 supports the harvester in its working position. A stay 20 is used to maintain the harvester part at right-angles to the thrasher 1 and a latching rod 34 engaging over a projection on the top of the member 15 holds the spindle of the wheel 28 horizontal. When it is desired to fold the harvester along the thrasher 1 the latching rod 34 is removed, permitting the wheel bracket to tilt about its pivot 31 until a second latching rod engages the projection on the member 15 and the latch of the member 15 released permitting it to swing about the vertical pivot 13 connecting it to the arm 11. The stay 20 is removed and the harvester permitted to swing round the pivot 5 castoring on the wheel 28 till it lies against the thrasher. A tie rod 38 is used to hold it in folded position. To give extra clearance when folded the platform 10, which is normally adjustable by a manually-operated link 55 to vary the height of cut, may be raised above the wheel 3. The support 8 comprises an inner fixed tube 36 over which a sleeve 43 attached to bearing members 37, 41 can rotate. Brackets 44 rigidly secured to the sleeve 43 carry bars 45, 46 to which angular frame pieces carrying the platform 10 and a backboard are pivoted. Link rods 52 extend from the angle pieces at the back of the backboard to arms projecting from the members 37, 41. To counterbalance the weight of the platform, springs secured at one end to a bracket on the support 8 are attached at the other to a head connected by a link to a flexible member 64 passing over pulleys 65, 67, on the bar 45 and connected to a cam member 39 on the bearing member 37. A brace is provided to hold the platform in its raised position. The reel associated with the platform may fold with it after disconnecting the drive.

Patent GB-385366-A (GB)
Abstract: 385,366. Fluid-actuated valves. WILTON, L. E., 10A, Newman Street, Oxford Street, London. June 17, 1932, No. 26204. [Class 135.] Valves controlled by pilot or relay valves.- A flushing valve comprising a piston-actuated main valve controlled by an auxiliary valve is provided with means to prevent the auxiliary valve being held partly open and with means to prevent the actuation of the auxiliary valve while a flush is taking place. The main actuating piston is formed by a cup-leather secured by a nut 7 to a tubular member 19, which carries at its lower end the main valve 10 held in place by the member 12. The member 12, which carries the seat 15 for a tilting disc auxiliary valve 13 forms a ported tubular guide 29 and supports an interchangeable tubular throttling member 25 whereby sufficient pressure is maintained in the inlet to actuate the piston. The auxiliary valve which has ports near its periphery is normally held to its seat by a spring 13<1> and has a depending stem 14 provided with a terminal enlargement 23. The actuating handle 1 is secured to a transverse shaft 30 mounted in a cover-plate 31 and provided with an internal arm 34. The arm 34 has a blade spring adapted to engage one or other of arms 38 on a segment 35 freely mounted on the shaft 30 and carrying a pin 17 adapted to displace the stem. In the normal position the stem 14 is vertical and the blade spring is under stress. When the handle is operated to bring the arm into contact with one or other of abutment surfaces 41 on the segment, the stem is slightly displaced and the spring released to complete rapidly the opening movement. As the main valve rises the stem is first further tilted as the projection 23 passes the pin and afterwards returns to its vertical position closing the auxiliary valve. To lock the actuating handle while a flush is taking place a pivoted catch 43 is arranged to engage one or other of two recesses 44 in a member 45 secured to the shaft 30. As the main valve closes the guide 29 engages a blade spring carried by the catch to release it.

Abstract: 909,560. Inking-apparatus. ALLERS ETABLISSEMENT A.S., CARL. Dec. 1, 1958, No. 38705/58. Class 100 (2). In an inking-apparatus comprising a fountain roller partly immersed in ink in a trough, the thickness of the ink film being regulated by a doctor blade, the roller is driven intermittently from a continuously rotating component through a pin and slot drive, the slot being shaped so that engagement of the pin and slot moves the roller forwards while disengagement moves it in reverse by a smaller amount, thus preventing the build-up of matter between the doctor blade and the roller. The fountain roller 2 of an ink fountain 1 for a printing-machine co-operates with an adjustable dust-blade 3, and is rotated intermittently by a continuously rotating electric motor through a shaft 21, gear 22, gear 11, rollers 10 on the gear 11, and slots 9 in a disc 8 on the fountain roller shaft 7. The axis of the gear 11 is within the periphery of the disc 8, and the leading faces 13 of the slots 9 are rounded at 14, so that at the end of its forward movement, the roller 2 is moved slightly backwards, to avoid collection of dirt at the blade 3. The degree of backward movement is variable by altering the axial distance between the shaft 7 and the shaft 12 of the gear 11, one or both shafts being mounted in eccentric bearings. Ink from the roller 2 is transferred to a distributer roller 6 by a transfer roller 5 of the construction described in Specification 908,692 the roller 5 being also driven by the motor.

IPC: H04N9/465
Filed: 1972-08-21
Abstract: 1401678 Colour television SONY CORP 21 Aug 1972 [23 Aug 1971] 38837/72 Heading H4F A PAL colour television receiver uses a oneline delay line 3 and a switch 2 operated at half line-frequency to produce a chrominance signal having fixed modulation axes and bursts of constant phase, the switch 2 being operated by a flip-flop circuit 5 controlled so that switch 2 passes only signals having desired modulation axes to demodulators 6 and 7. In the embodiment shown the desired R-Y modulation axis is at + 90 degrees relative to the B-Y modulation axis; and the bursts in the signals passed by switch 2 are separated at 8 and control a reference oscillator 10 which feeds the demodulators 6 and 7 via 45 degree phase shifter 11 and 135 degree phase shifter 12 respectively. The output of phase shifter 12 is also passed to demodulators 13, 14 which receive the incoming chrominance signal from 1 and the delayed chrominance signal from 3 respectively. If switch 2 is operating as desired the output of phase shifter 11 has +(R-Y) phase, the output of phase shifter 12 has +(B-Y) phase and the outputs of demodulators 13 and 14 are equal, so that no signal is derived at the output of subtractor 15 and no signal is derived from control circuit 16. If, however, switch 2 is operating in antiphase to the desired operation, the output of phase shifter 11 has -(B-Y) phase, the output of phase shifter 12 has +(R-Y) phase, the outputs of demodulators 13 and 14 are antiphase and the alternating output of subtractor 15 causes control circuit 16 to change the state of switch 2 via flip-flop 5. Alternatively one demodulator (18, Fig. 6, not shown) may be used instead of demodulators 13, 14, the outputs of 1 and 3 being added before being supplied to the demodulator, and the control circuit producing an output signal in response to a zero output from the demodulator. In further embodiments (Figs. 8, 10, not shown) the outputs or inputs of the demodulators 13, 14 are added and subtracted, the resulting signals then being fed to a comparator circuit to derive a control signal to change the operation of switch 2 if necessary. In alternative embodiments (Figs. 11, 13, not shown) four demodulators are used in place of demodulators 13, 14, two (38, 40) being fed with the signal from 1 and two (39, 41) being fed with the delayed signal from 3, one demodulator of each pair (38, 39) receiving a reference signal from phase shifter 12 and the other demodulators (40, 41) receiving a reference signal from phase shifter 11, the resulting signals from the demodulators receiving the same reference signal being added or subtracted, the resulting two signals being passed to a comparator. In all the embodiments the signals fed to the demodulators such as 13, 14 may be the complete chrominance signals or only the bursts or the chrominance signals with the bursts removed. Signals in antiphase with those from phaseshifters, 11, 12 may be used as the reference signals.

Abstract: 900,060. Cleaning endless conveyers during operation thereof. DORRIES A.G., O. Nov. 15, 1960 [Feb. 10, 1960], No. 39240/60. Class 78(1). In apparatus for cleaning conveyer belts, e.g. the " felts " of papermaking machines during operation thereof, cleaning liquid is applied to one face of the belt and caused to form a pool of the fluid which is vibrated by an ultrasonic vibrator to loosen the dirt, and the fluid is subsequently withdrawn from the belt by suction applied either to the opposite face of the belt or to the same face of the belt downstream of the point at which the liquid is applied. In one embodiment, Fig. 1, the liquid is applied under pressure via a hose 13 to a chamber 2 containing a vibrator 1, a suction chamber 3 to which suction is applied via a hose 14 being arranged downstream of the chamber 2. The chambers 2, 3 are formed in a casting over which a cover-plate 15 having corresponding apertures is fitted, plate 15 being arranged to press against the working face of the belt 4. The casting is traversed across the belt during operation by a screw 17 co-operating with a guide rod 19. In the embodiment of Fig. 3 the vibrator is in the suction chamber 3, chamber 2 being omitted from the casting and replaced by a nozzle 5 carried by a mounting 16 which is traversed by another screw 18 and guide rod 20. In another embodiment (Fig. 6, not shown), the suction chamber 3 is arranged below the belt as in Fig. 1, but the vibrator and pressure chamber 2 are arranged in a separate casting above the belt which is traversed by another screw 18 and guide rod 20 as in the embodiment of Fig. 3.
