Abstract: 1478765 Sheet-transferring and turning device HEIDELBERGER DRUCKMASCHINEN AG 20 May 1975 [16 Oct 1974] 21507/75 Heading B6C A device for transferring and turning sheets between two printing units to enable both sides of a sheet to be printed comprises three drums, a transfer drum (1), Fig. 1 (not shown), a storage drum 2 and a turning drum 3, the opposite ends of a sheet 6 being gripped for part of the period of rotation of storage drum 2, respectively by grippers 5 on the storage drum and grippers 7 on turning drum 3, the grippers on the two drums exerting unequal holding forces to tension the sheet 6 prior to release by the grippers 5. In preferred embodiments, grippers 5 clamp the leading edge of a sheet, while grippers 7 in the form of tongs grip the trailing edge as it passes through centre line 34 between the drums but with a lesser force. While the clamping grippers 5 move through a distance a, the tongs grippers 7 only move a distance a<SP>1</SP>, resulting in the sheet 6 being tensioned and the trailing edge being drawn through the tongs grippers by an amount equal to a-a<SP>1</SP>. The clamping grippers 5 then release the leading edge while the tongs grippers 7 increase their holding force. The gripping pressure and timing of the operation of the tongs grippers is controlled by cams 26, 27, through cam followers 24, 25 and toothed segments 22, 22<SP>1</SP> coacting with spindles 20, 30 supporting the arms of the tongs. The movement of the sheet with respect to the grippers 7 serves to register the sheet at the next printing position.

Abstract: 964,831. Soldering. BURROUGHS CORPORATION. June 4, 1962 [June 5, 1961], No. 21513/62. Heading B3R. [Also in Division H1] A matrix of semi-conductor devices is made by supporting the devices in the positions to be occupied in the complete array, placing a printed circuit in registry with one side of the devices, and conductively bonding the devices to the circuit, and then similarly attaching a second printed circuit to the other sides of the devices. As shown, Fig. 4, a printed circuit consists of an insulating substrate 10 with conductors 12 formed on its surface. These conductors are coated with solder and flux. As shown, Fig. 3, a plurality of silicon diodes 22, each with a conductive solderable coating 28 bonded to both ends, are attached to a plate 24 by a releasable adhesive 26. The diodes may be formed by etching or ultrasonic machining. The outer ends of the diodes coated with flux 30 and then placed upon the printed circuit, Fig. 4. The assembly is then placed in a device which applies pressure to the assembly and heats the printed circuit to solder the diodes to the printed circuit. The plate 24 is then removed by dissolving the adhesive 26, and the assembly is then placed in boiling detergent, cleaned in water and/or alcohol and dried. A second printed circuit is then soldered to the exposed ends of the diodes in a similar manner. The completed assembly is etched to remove any roughness, and lead wires may be soldered to the pads 12<SP>1</SP> of the conductors 12, or the assembly may be used as a plug-in unit. As shown, Fig. 5, the device for performing the soldering operation consists of a U-shaped member 36, 38, 40, with an arm 40, carrying a pressure pad 42, pivoted at its end 44 to member 46 and biased by spring 48 towards leg 38. Leg 38 is made of metal and has a heating element 50, supplied from a source of current 54, mounted on its underside. In use, pad 42 presses plate 24 carrying diodes 22 against the printed circuit 10 which rests on the leg 38. The heat from the element 50 passes through the leg 38 and melts the coating of solder on the conductors 12.

Title: Improvements in transfer mechanism for totalizers of calculating and other registering machines
Filed: 1921-08-16
Abstract: 168,311. Tabulating Machine Co., (Assignees of Lake, C. D.). Aug. 24, 1920, [Convention date]. Transfer mechanism.-Transfer is controlled electrically, but the actual movements of the wheels are effected simultaneously and mechanically. For each numeral-wheel, there is a duplex arrangement of contacts which permit simultaneous consequent transfers when the next lower wheel moves from 9 to 0. The invention is shown as applied to the totalizers of a statistical tabulating machine such as that described in Specification 131,277, wherein the passage of a perforated card effects electrically a differential movement of the totalizer wheels in accordance with the serial positions of the perforations. This movement is derived from a primary shaft 16 through a sliding clutch shifted by electromagnetic means, the time of engagement of the clutch determining the extent of rotation of the corresponding numeral wheel. When a numeral wheel 3 moves to show nine, a cam 20, through a bell-crank 23, moves a lever 26 pivoted at 27 so as to release a contact arm 29 which then rests upon a tooth of a notched yoke 31. When the wheel advances again the cam portion 22 rocks the lever still farther to the left and so allows a second contact arm 30 to fall through a notch in the yoke 31 into engagement with a fixed contact bar 54. During the transfer-effecting cycle of movement of the machine the circuit to the contact bar 54 is closed, and consequently current flows bv wav of the contact arm 30 to the counter-operation controlling magnet of the next higher wheel so as subsequently to move this on by unity. If a wheel standing at nine receives a transfer, the descent of contact arms 29 into engagement with arm 30 due to a lowering of yoke 31 permits the passage of the current also to the magnet of the next higher wheel. The yoke 31 is lowered during the transfer cycle, by connection with a cam 40 on the main shaft 16 through a lever 36 and link 35. At the end of the cycle, the yoke is rocked to slightly above normal position in order to raise the contact arms to allow them to reset upon the lever 26.
