Abstract: 168,106. British Thomson - Houston Co., Ltd., Young, A. P., and Warren, H. W. H. April 22, 1920. Magneto-electric machines.-In ignition magnetos one half of the voltage wave is utilized for ignition purposes only and a portion of the next half-wave for lighting or other purposes, there being definite periods after the opening of the contacts to produce an ignition spark and prior to the closing of the contacts during which no current is taken from the primary winding. Fig. 3 shows the voltage wave 10, the contact-breaker operated by the cam 4, Fig. 1, closing at the point 11 and breaking at the point 12, primary current for lighting &c. being taken off between the points 13, 14. Fig. 2 shows a brush 7 which may be fitted to the end cover and makes contact with a metal segment 8 carried on the disc 9 and connected to the contact-breaker to supply current from the primary to the lighting &c. circuit.

Abstract: 472,431. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., and BOWSHER, E. A. H. June 19, 1936, No. 17103. [Class 40 (i)] In a system for signalling by D.C. over A.C. power mains, a resistance R shunted by a rectifier MR is adapted to be switched into or out of the circuit by the signalling key S1. When the resistance and rectifier are switched into circuit equality of amplitude of alternate half-waves is destroyed, and relay D sensitive to D.C. is operated. The relay D is connected across an A.C. bridge circuit which is balanced for normal A.C. flow. A key S2 is adapted to reverse the effective direction of the rectifier in order that D.C. effects of opposite polarity may be produced. In this case, a polarized relay D is provided. In an alternative receiving circuit arrangement, the relay D is connected in series with the secondary winding S directly across the mains, operation of relay D by normal A.C. being prevented by providing a low resistance primary winding P and making the inductance of the primary equal to the mutual inductance of the transformer.

Abstract: 318,684. Winkler, A., and Dunnebier, M. June 14, 1928. Addition to 302,641. Feeding articles in predetermined attitude by lifting from loose assemblage in bin. -The apparatus described in the parent Specification is modified by reciprocating the wavy guides 32 at one end instead of at an intermediate point, or alternatively, reciprocating the conveyer 46 transversely to the line of travel of the goods, or moving it bodily in a circular path in a horizontal plane and reciprocating the guides 32 in the line of travel of the goods. In the form shown in Fig. 1, the guides 32 are held at one end in the stationary cross member 34 and at the other end in the cross member 36 which is reciprocated as described in the parent Specification by a bell crank 48, 49. In the alternative form shown in Fig. 2, the table 4 carrying the conveyer 46 is secured at one end to a bracket 102 which is pivoted on a bracket 103 on the machine base 3, At the other end of the table, a frame 106 is secured which is pivoted at 108 to a lower frame 107 which slides on the shaft 54 and embraces the sides of the band pulley 25. Downwardly projecting arms on the frame 107 are joined by a cross bar 109 to which a crank operated connecting rod 114 is pivoted. The crank has an adjustable throw and is driven through bevels from a friction disc 68 so that the conveyer 46 is oscillated about the pivot 105. The roller 31 may be resiliently mounted to keep the belt stretched evenly during the movements of the frame. The guides 32 rest at one end on a plate 117, and, adjacent to the other end, are connected to a cross bar 35 which slides on plates 119 secured to the table 4 and has projecting end pins 120 engaging with rocking levers 121. One of the levers 121 is formed as a bell crank, one arm of which is slotted to adjustably receive a rod 123 connected to a crank pin on the friction disc 68. The guides 32 are thus reciprocated longitudinally and are guided by the cross bar 34 engaging upturned ends 118 of the plate 117, which is positioned over the end of the coating conveyer 1 and is level with the conveyer 46. The drive of the feeding conveyer 8 and brush 18 is effected as in the parent Specification. The slide 87 interposed between the conveyer 8 and the guides 32 is shaped as shown in Fig. 5, ridges c of roof like section and increasing in height and slope towards the lower end forming troughs b of increasing depth leading to the guides 32. Pins d are fixed in staggered relationship on the upper portions of the ridges c and direct work pieces into the troughs b as shown at a, a<1>, all. The lower ends of the ridges are sufficiently wide to include the whole scope of the reciprocation of the guides 32. Alternatively to the pins d, alternate ridges c may be made short with their upper ends projecting above the slide.

Abstract: The object of the invention is to make possible a rapid and accurate butt joining of two paper webs (N1, N2) with a narrow and regular butt joint and letterings and/or designs on the paper webs having a matching transition to one another, in particular in packaging machines, without interrupting operation. To this end, the new paper web (N2) is adjusted parallel to and below or above the old, travelling paper web (N1) and, with the aid of a temporarily drivable winding roll (14), is accelerated to the same velocity as the old paper web (N1). Subsequently, the two paper webs (N1, N2) are cut through simultaneously with the aid of a cutting device (10, 11) by means of a single cut. The cut-off, leading starting piece of the new paper web (N2) is wound entirely onto the winding roll (14) and thereby removed. The trailing cut end of the old paper web (N1) which is conveyed further by a pair of drive rolls (17, 18) and the leading cut end, bearing in an abutting manner against the said trailing cut end, of the new paper web (N2) which is conveyed further at the same velocity by a pair of drive rolls (4, 104) are joined to one another in an adhesive tape unit (5, 105) by means of an adhesive tape piece (S) bridging the cut line. <IMAGE>

Abstract: 1425125 Tape reader EX-CELL-O CORP 12 April 1973 [12 April 1972] 17731/73 Heading G4M A punched tape reader is arranged to block faulty signals created by incorrect positioning as the tape is incremented step by step. Directional commands for the reader stepping motor 10 pass AND gate 17, clock pulse generator 18, bidirectional counter 19 and a phase decoder 21. Clock pulse signals are also fed to a delay pulse generator 22, an anti-jitter pulse generator 23 which feeds the phase decoder and a step rate pulse generator. A signal pulse responding to the sprocket hole is fed to flip-flop 28 so that the leading edge operates flip-flop 27 and the trailing edge operates flip-flop 28. As the sprocket hole passes through the sensor a pulse is produced and when it passes out of the region of the sensor the pulse is terminated. If registration is correct any variation in sprocket hole position, i.e. due to bounce or jitter or oscillations occurs inside the sensing region. If registration is incorrect the sprocket hole may move outside the sensing region and back again one or more times before achieving a rest position. These oscillations may produce faulty signals causing duplicated read-out of the corresponding row of data. A clock pulse advancing the motor will, via delay pulse generator 22, produce signal SS1 setting flip-flop 27 so that the Q output FF3 is at a high level and holds the flip-flop set for a period such that jitter oscillations cannot be falsely detected. Flip-flop 27 is reset by the feed hole signal when the delay pulse generator is reset and further feed hole signals are not effective to set the flip-flop. Flip-flop 28 is set by CP and reset on detection of the trailing edge of the feed hole. When FF4 is high and FF3 is characters or holes. After delay pulse generator 22 resets flip-flop 27 is reset as the leading edge of the next sprocket hole is sensed. SFH behigh SFH is low to signal the reader is between comes high to indicate sensing of the next character and is not affected by feed hole signals until a further reader advance pulse restarts the sequence.
