Title: Improvements relating to apparatus for sensing characters represented by perforations in a record medium
IPC: G06K15/00
Filed: 1965-06-08
Abstract: 1,071,128. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 8, 1965 [June 18, 1964], No. 24141/65. Heading B6F. [Also in Division G4] General.-A record card on which characters are represented by characteristic arrangements of perforations is sensed pneumatically by apparatus which includes a plurality of sets of normally discontinuous ducting, there being one set for each character and each set being rendered continuous only by the corresponding characteristic arrangement of perforations on the record card so as to provide an air pressure signal to operate the appropriate type member of associated printing apparatus. Card feeding and type selection.-Rollers (13), Fig. 1 (not shown) feed a card (11) column-bycolumn past the sets of ducting (18) which are parallel to the card columns. Each set comprises two or more junctions between ducts (40, 42) or (51, 52), Figs. 2, 3 (not shown). The Fig. 2 junction requires a perforation (43) to be present in card (11) for air pressure to be transmitted to duct (42), two such junctions being necessary at row positions 1, 12, for example, to detect the character " A ", and the output of duct (42) being connected to operate the corresponding type-member piston to print this character at the same column position at the edge of card (11) or on a separate record. A spring-loaded piston (46) normally blocks the junction in the absence of a card. The Fig. 3 junction is such that pressurized air in duct (51) normally escapes through the vertical duct and a groove (53) in spring-loaded piston (56), pressure only being transmitted to duct (52) when the vertical duct is closed by a non- perforated portion of card (11). One or more junctions of the latter type are used in combination with Fig. 2 junctions where it is necessary to distinguish between characters having common perforations. Type-member impression arrangement, Fig. 4, shows the arrangement for character " A ". Pressure only appears at duct 89 when perforations are present at rows 1 and 12. Spool valve 74 is normally in its upper position because pressurized air from duct 77 leaks past lands on the valve and a higher pressure is maintained beneath the valve by means of a restricted throat 78a. A pressure signal from duct 89 forces the valve down to vent the cavity above piston 81 to atmosphere through ducts 84, 75. High pressure from duct 77 then passes through duct 85 to force piston 81 upwards and urges type-member 26 against ink ribbon 27 and card 11. As piston 81 rises, feedback duct 88 is opened and high pressure is supplied under the spool valve 74 to return it to the position shown, whereupon high pressure is also fed through duct 84 to force the type-member piston 81 down again. The ink ribbon 27 is an endless loop driven by pinch rolls and reinked by a roll from the wick of an inking capsule.

Title: Improvements in or relating to web-handling apparatus incorporating fluid actuated brakes

IPC: F16D63/00
Filed: 1964-06-11
Abstract: 1,082,802. Feeding webs. WITTON-JAMES Ltd. July 15, 1965 [June 11, 1964], No. 24379/64. Heading B6B. [Also in Division F2] A brake for controlling or stopping a reel from which a running web of material is drawn in a web handling apparatus comprises a multichambered actuator 1 acting on an axially slidable brake pad 3 to move a rotatable brake disc against an axially fixed brake pad 2, the multi-chambered actuator being formed with three air chambers 11, 12 and 13 which are separated by diaphragms 7 and 8. A diaphragm 9 forms the outer wall of the chamber 13 and carries the pressure plate 4 of the brake pad 3. Control means, in the form of a pressure switch 17, is provided to be operated in response to associated sensing means constituted by a main tension control valve (not shown) of the web handling apparatus to which the brake is attached. The effect of the pressure switch 17 on the. brake actuator 1 is that the pressure applied to the. chamber 12 will increase at the same rate as the pressure being supplied directly to the chambers 11 and 13 from the main tension control valve until a maximum value pressure is reached in the chamber 12. Additional pressure from the main tension control valve will increase the pressure in chambers 11 and 13 whilst the pressure in chamber 12 will decrease to atmospheric pressure. If the pressure from the main tension control valve decreases, the pressure in the chambers 11 and 13 will decrease at the same rate and at a certain value the pressure in the chamber 12 will rise to the same pressure as that in chambers 11 and 13. If the air in chamber 12 is at atmospheric pressure and chambers 11 and 13 are pressurized whilst the effect on diaphragm 9 will to some extent be nullified by the air pressure in chamber 13 acting on diaphragm 8, the effect is not cancelled since the area of diaphragm 8 is less than diaphragm 9. The air pressure in the chamber 11 now acts on a larger area of diaphragm 7 and permits this diaphragm to considerably increase the braking force to the pad 3 for a given air pressure, since the force is not being equalized by the chamber 12.
