Title: Automatic repeat mechanism for a business machine
IPC: G06C15/04
Filed: 1971-06-22
Abstract: 1341442 Repeated operation of business machines NATIONAL CASH REGISTER CO 22 June 1971 [29 June 1970] 29163/71 Heading G4B  A business machine having amount keys (20) and transaction keys (22) (Fig. 1, not shown) for operating the machine to enter amounts set up on the amount keys further includes a plurality of selectively operable repeat keys (23) for controlling the repeated operation of the machine a number of times as determined by the particular repeat key depressed. In the embodiment described a respective primary transaction rack is positioned according to the key depressed in each transaction row (1), (2) and (3) and a shaft 86, Fig. 4, moves to a corresponding extent transmitting its movement via a square shaft 116 to a selecting plate 122, Fig. 7. The plate is formed with cut-outs 123 of differing depths about its periphery which are selectively located adjacent a feeler 133 which is freed by rotation of a segment 125 to pivot clockwise about a stud 134 under the action of a spring 147 to sense the depth of the cut-out. This clockwise pivoting is transmitted to a stop member (141) (Fig. 8, not shown) to position a particular part of stop surface (173) in the path of a flange (174) on the primary rack (115). Thus the primary rack is appropriately positioned for the next machine operation. During each cycle of machine operation a cam (58) (Fig. 5, not shown) is rotated to move link 53, Fig. 4, to the right resulting in the anticlockwise rotation of yoke 45 and clockwise rotation of feeler arm 47. If a stud 92 on the arm 47 senses a low spot on a gear 72, the position of which is determined by the primary rack through shaft 86, a portion of the yoke 45 is moved behind a stud 44 on a drive arm 24, and on further rotation of the yoke 45 the drive arm 24 is moved to the left, where it is latched by a latch rod 37, and in this position actuates a switch 175 which serves to energize a solenoid 111, Fig. 6. Repeat cycling.-When energized the solenoid 111 rotates an arm 104 to move a blocking surface 114 of a pawl 101, mounted on an arm 94 pinned to the key-lock line 93 of the machine which is rotated anti-clockwise to initiate a machine operation, out of contact with a stud 98 on a drive link 96. Thus when the link 96 is moved to the right at the end of an operation, which normally rotates the arm 94 clockwise to stop the machine, the stud 98 moves in slot 97 and does not rotate arm 94, the machine therefore remaining in operation for a further cycle. Repeat cycling is maintained in this way until the primary rack has been indexed back to a position in which its associated gear-wheels 72 present a low spot to the feeler arm 47 associated with a release slide (41) (Fig. 3, not shown) the subsequent movement of which releases the latched drive slide 24, de-energizing the solenoid 111 and hence allowing the stoppage of the machine at the end of that cycle. Specification 1,220,913 is referred to.

Abstract: 340,539. Sewing-machines. HANSEN, J. B., 13, Maagevej, Copenhagen. Oct. 1, 1929, No. 29764. [Class 112.] Chain stitching.-In a chain stitch machine for sewing boot soles to the uppers, the stroke of the needle-driving mechanism is adjusted automatically by the presser-bar according to the thickness of the work. The needle 5 is carried in a bar 4 reciprocating in the frame 1 under the action of the shaft 15a. A link 14 is pivoted to a crank plate 15 on the shaft and terminates in a block 13 sliding in the slot 16 in the lower part of the needle-bar. The presserfoot 3 is carried by the bar 2 reciprocating in the frame 1 and having a rack 7 engaging a toothed quadrant 9 associated with the spring plunger 11 which forms a stop for the block 13. The thickness of the work causes a rise or fall of the presser-foot which in turn operates on the buadrant 9 to advance or retract the stop 11. The stroke of the needle depends on the amount of play allowed to the block 13 before it abuts against the stop 11 and lifts the needle-bar 4, and is therefore automatically adjusted by the position of the presser-foot due to the thickness of the work.

Filed: 1958-09-17
Abstract: 883,865. Boundary layer control on aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Sept. 16, 1959 [Sept. 17, 1958 ; June 16; 1959], Nos. 29802/58 and 20585/59. Class 4. An aerofoil boundary layer control system comprises an aerofoil with first and second side surfaces aud a rounded trailing edge surface, and formed with first and second spanwiseextending discharge apertures in its first and second side surfaces respectively, the apertures being arranged to discharge fluid streams as layers rearwardly over the side surfaces towards the trailing edge, and a control operable to vary the flow of the two streams relative to one another. An aerofoil comprising a wing 2 is of substantially elliptical cross-section and is formed in its surface with boundary layer control apertures or slots 10, 11, 12, 13, 14 and 15, each comprising a spanwise extending recess in the wing surface. Each recess has one surface 16 which fairs into the wing profile and another face 17 substantially normal to the surface 16 to form a step, face 17 being formed with discrete apertures 18 or slots which communicate with manifolds 21, 22 and 23 for slots 10, 11 and 12 and manifolds 25 and 26 for slots 14 and 15, respectively connected by conduits and valves 27, 33 ; 28, 34 ; 29, 35; 31, 37 and 32, 38 to a common manifold supplied with pressure air from an engine compressor or an auxiliary compressor, whereby compressed air may be supplied selectively to the slots. Similar provision is made for slot 13 and is shown in Fig. 3, air from slots 10, 11, 13 and 14 is directed towards the trailing edge of the wing whereas air from slots 12 and 15 is directed away from it. Under normal flight conditions valves 33 and 34 are opened to supply air to slots 10 and 11 such air emerging over upper and lower wing surfaces as sheet jets to provide a boundary layer control effect and, as shown at 39, Fig. 3, to close up the wake which would otherwise be set up round the trailing edge. By varying the relative mass flows and/or velocities of the air jets the rear stagnation point X can be moved from the neutral position of Fig. 3, to any point between slots 10 and 11 with consequent variation in circulation and lift on the wing, analogous to that normally effected by ailerons. To achieve a large increase in wing lift, the air supply to slot 11 is shut off while valves 35, 37 and 38 are opened to supply air to slots 12, 14 and 15 in addition to slot 10. At the same time air is supplied to slot 13 so that the stagnation point X is located between slots 12 and 13 resulting in considerable increase in life analogous to that normally effected by flaps. Slots 14 and 15 could be replaced by a single aperture or a greater number of apertures may be provided between apertures 10 and 11 to promote flow of the boundary layer around the wing trailing edge. The invention may be applied to tailplanes and fins of substantially elliptical cross-section or to helicopter rotor blades.
