Title: Printing machines
IPC: B41L47/42
Filed: 1966-05-10
Abstract: 1,144,934. Printing apparatus. ADDRESSOGRAPH MULTIGRAPH CORP. 10 May, 1966 [4 Oct., 1965], No. 20756/66. Heading B6C. In a machine for printing sales data &c. on a near-vertically disposed sales form the printing operation is automatically effected by motor driven means after a pivoted head carrying the form and the printing surfaces is swung into position adjacent one face of the machine. As shown the machine is roughly cubical in shape and the head 104-spring-loaded into its open position-forms one face thereof. The box part of the machine houses an electric motor 28 and lever linkage means by which the motor is actuated on closure of the head. A platen roller P is loosely mounted on a spindle F2 parallel with the plane of the closed head, Fig. 3, and this roller may be readily removed by pulling the upper end of the spindle 72 forward away from its mounting. In operation, projections 136, 137 at each side of the head move outwardly as the latter is manually closed into operative position about a spindle 154 and in so doing release a latch mechanism such that a motor switch energizes the motor 28. The platen roller is then driven across the head during a printing stroke to a position where an abutment on the lower limb of the U-shaped arm carrying the roller engages a trip mechanism which releases the head allowing it to spring back to its open position. The motor is not de-energized however and continues to operate thus returning the platen to its original position where a further trip mechanism is actuated to shut the machine down. The platen roller may be of the selfinking type or carbon paper may be inserted between the printing surfaces and the form. The printing surfaces comprise a fixed printing plate, a dating device and a customer's card. The latter is readily removable a spring-loaded mouse trap type U-shaped bar being used to hold it in position on the head.

Abstract: 822,474. Making gilled tubes for radiators. USINES CHAUSSON S.A., DES. July 2, 1957 [July 20, 1956], No. 20934/57. Class 83 (2). A machine for engaging circulation tubes in rows of gills particularly closely-spaced gills comprises holding members for the gills located so that the protruding ends of partially-engaged tubes are placed against a vibrating element which also has a movement in the direction of engagement. A magazine 5, Fig. 1, containing gills 6 is located between plates 3, 4 on a table 2 supported by a frame 1. Tubes 7 already partially engaged in and projecting from the upper gills contact the bottom of a sole-plate 31 connected to a vibrator 30 carried on a shelf 27 in turn supported by piston-rods 26 of cylinders 24. Screws 14 mounted in bearings 15 and entering tapped bushings 13 are rotated by a motor, through bevel gearing on shafts 20, 21, 22, thus moving plates 11, 12 closer together or farther apart. Plates 9 and 10 attached to plates 11, 12 carry tips 8 which are entered and withdrawn through perforations in the plates 3, 4 and the magazine to engage between the gills 6 and support them when the tubes 7 are pushed downwards by the operation of cylinders 24. After the complete engagement of the tubes in the gills by the downward movement of the vibrating sole-plate 31 the shelf 27 is raised and the tips 8 are partially withdrawn but still remain engaged in the magazine walls. Laterally-acting jacks then operate thrust parts through openings in an end-plate to eject the radiator cluster from the magazine 5. The tips 8 are then completely withdrawn and the magazine removed. Where gills are set wide apart the tips 8 may not be incorporated in the machine.

Abstract: 1,132,484. Control of D.C. motors. INTERNATIONAL BUSINESS MACHINES CORP 12 May, 1966 [1 June, 1965], No. 21009/66. Heading H2J. An electric servomotor in a positional system is initially accelerated and then braked by reverse current when the integrated output of a tachogenerator reaches a reference level which is adjusted so that the driven element, e.g. a magnetic pick-up traversing a rotating recording disc, comes to rest at the desired point. The motor 13 is energized through a transistor bridge 12 from a high-gain D.C. amplifier 11. The output of the tachogenerator 14 is supplied to the amplifier but is normally opposed and swamped by the drive signal from forward or reverse gates 18, 19; when this is cut off by a signal from the transistor integrator 15 the tachogenerator output brakes the motor to near standstill, when a mechanical indent ensures accurate location.
