Title: Photocopying machine
IPC: G03B27/30
Filed: 1965-06-28
Abstract: 1,092,676. Photographic copying apparatus. ADDRESSOGRAPH-MULTIGRAPH CORPORATION, CHARLES BRUNING DIVISION. June 28, 1965 [Dec. 2, 1964], No. 27262/65. Heading G2A. In a combined contact-printing and vapourdeveloping machine for diazo materials, the original or tracing from which the copy is made is fed out of the machine into a receiving tray 42, which tray is detachable and can be secured in various positions 40a, 40b, 40c, according to the length of the said original, which may vary widely. The original 14 and copy sheet 12 are fed in together, and conveyed by a plurality of belts 18, 22 round the transparent exposure cylinder 26. The two sheets are then separated by being passed between respective suction tanks 36, 34, the latter carrying the original 14 to the adjustable tray 42. The top tray position 40a is used when the originals are relatively short sheets, which are then stacked in sequence thereon. When the tray is in the middle position 40b, the leading edge of the sheet tends to move towards the right, so that the sheet turns completely over, and is now correctly positioned for re-insertion into the machine. In the lowest position 40c, suitable when long sheets are being used, the said sheets tend to curl and so form themselves into a roll. Fig. 5 (not shown) is a more detailed view of the manner of supporting the tray in its different positions, and the mechanism for adjusting it from one position to another. Fig. 3 (not shown) is a more detailed view of the suction tank 34, which has on its surface a plurality of apertures (102). A series of raised portions (34a) act as guides for the respective separate portions of the belt 30, which pass round tank 34 between the portions (34a). The belts themselves are perforated, as are the raised portions (34a), so that the sheet 14 is thus held against the belts by the vacuum within tank 34. The copy sheet 12, held by suction against belts 22, is carried up to the ammonia processing chamber, and then on further between belts 48 and 56. It may then be discharged from the machine through either a rear exit 60 or a front exit 67. The rear exit is used for large sheets, and a gate 62 is pivoted to the "open" position shown in full lines to allow the sheet to pass out. For small sheets, gate 62 is pivoted to the "closed" position shown in dashed lines, so that the sheets are guided back towards a second gate 64. If this is in the position shown in full lines, the sheet is guided above it, above a further guide means 66, and out into a receiving tray 68. For a shorter sheet still, the gate is rotated into the position shown in dashed lines. The sheet is then deflected downwards on to the upper run 56a of belt 56, which again deposits it in tray 68. Fig. 8 (not shown) is an arrangement for metering and controlling the admission of ammonia to the developing tank 46, which forms the subjectmatter of Specification 1, 100, 238.

Abstract: 528,560. Centrifugal dust extractors. PFEFFER, H. W., and DANZ, H. O. Oct. 5, 1939, No. 27278. [Class 23] Dust is separated from gases in a primary separator containing a number of units, each of which comprises a vertical tube 3 with an annular axial entry provided with helical vanes 5 to cause the gas stream to rotate. The dust which is thrown to the wall by centrifugal force is withdrawn through the annular space 7 between the skirt 6 and the wall of the tube to the hopper 8, while the clean gas passes through the tube 21 and the tubes 22 to the space 23 from which it passes to the discharge pipe 24. The dust with a small portion of the gas passes from the hoppers 8 to the large collector 10. It is then conveyed by the pipe 11 to the separator 14 where it is subject to further treatment; the separated dust drops to the container 17 while the clean gas travels by the pipes 18, 20 to the inlet header 2 of the primary separator. A fan 19 between the pipes 18, 20 maintains the circulatory flow. In a modification the lower part of the separator is formed by a venturi tube 25 forming an annular gap 27 with the clean gas outlet tube 28. The dust is discharged through the gap 27 and passes to the second separator.

Abstract: 1,122,601. Fluid-pressure brakes. BENDIX CORP. 22 June, 1966 [28 June, 1965], No. 27855/66. Heading F2F. In a fluid pressure servomotor for a vehicle braking system, the servomotor housing 12, 14 comprises a tubular collar 28 affixed to a member 20 separating the housing 12, 14 into two variable volume chambers 24, 26, the tubular collar 28 also being affixed to a fixed panel 52 of the vehicle to which it is to be mounted, and a pedal operated push rod member 108 is provided to control a valve means 104 adapted to control the communication of at least two different pressures to the chambers and reciprocating in the collar 28 to pressurize a master cylinder 60 through the intermediary of a link 78 operatively connected to the master cylinder piston 72 such that the housing 12, 14 is adapted to reciprocate on the collar 28 and is adapted to be pulled as a unit with the master cylinder towards the fixed panel 52 upon actuation of the valve means 104 while maintaining the valve means to limit the travel of the push-rod member 108. In the position illustrated in the drawing, the servomotor is shown in its released position wherein vacuum being supplied through a check valve connection 130 is supplied via axial passage 124, open valve 104, radial passage 128, control passage 98 and radial passage 96 to the second variable volume chamber 26, thus suspending the diaphragm 18 and the member 20 in a vacuum suspended state. When the operator depresses a brake pedal (not shown), the control rod 108 is moved forwardly so that a poppet valve abuts against a valve seat 122 of a valve body 82 of the valve means 104. In this position, the vacuum communication by means of the axial passage 124 is closed off from the valve chamber 126 and the control valve is in a lapped position. Upon further depression of the brake pedal, a rearwardly facing valve seat 118 is removed from the forward face 120 of the poppet valve to communicate atmospheric air pressure via a filter 102 to the valve chamber 126 and subsequently to the second variable volume chamber 26. The valve body 82 is held by a spring 94 to the fixed tubular collar 28 and the atmospheric air pressure in the chamber 26 will draw the servomotor 10 rearwardly on the tubular collar 28 to compress the spring 94 and draw the master cylinder 60 rearwardly with respect to the piston 72 to pressurize the chamber 68 of the master cylinder. In the event of a power failure, the push rod 108 may be forced to abut a key member 132 within a slot 134 of the valve body 82 so that the valve body 82 may be projected forwardly of the tubular collar 28 to reciprocate the piston 72 forwardly in the chamber 68 of the master cylinder 60 to pressurize the brake system. A reaction disc 80 is provided between the link 78 and the valve body 82. A guide pin 53, located on a flange 48 of the tubular collar 28, provides a further guide for the servomotor 10 in its reciprocation on the collar 28.
