Filed: 1971-09-02
Abstract: 1309980 Feeding sheets R HEPP 2 Sept 1971 [7 Sept 1970 11 Aug 1971] 40957/71 Heading B8R Opening folded signatures.-Means for opening folded signatures comprises a pair of upper or first spreading members 13, 13a, Fig. 2, carrying suction cups or gripping members 15, 15a, a pair of lower spreading members 14, 14a carrying suction cups 16, 16a, and a separating member 30 selective movable to a centre position, Figs. 2 and 11, a left-hand position, Fig. 1e, or a right-hand position, according to the makeup of a signature assembly to be opened. One or both of the upper members may be rendered inoperable. Each of the lower members 14, 14a comprises a fixed housing 18, Figs. 3 and 8, outside the transport path of the signatures, and in which is rotatable a shaft 20, Figs. 3, 6 8 and 10 carrying a plate 19 and also supporting at one end a rotatable carrier 21 having at one end an arm 22 carrying the suction cup 16 or 16a and at the other end a bevel gear 24 meshing with a toothed segment 25 pivoted at 26 to the plate 19. The segment 25 has eccentrically mounted thereon a roller 27 urged by a spring 29 against a guide track having two parts 28a, 28b on the housing 18. As the shaft rotates, the roller 27 passes on to the part 28b of greater radius, allowing the spring to move the segment to rotate the carrier 21 and project the suction cup into the transport path, Fig. 10, whence it is retracted after the opening operation so as to allow free passage between the members 14, 14a of signature components opened by the members 13, 13a. The member 30, Figs. 1e, 2 and 11, is cyclically reciprocated, through a rod 31 slidable in a guide 36, by a rotating eccentric roller 32. The member 30 is settable in its three positions according to whether neither of the magnets 34, 35, the magnet 34, or the magnet 35, is energized to pull up the corresponding end of the guide 36. In one example of a signature assembly, Fig. 1e, an outer sheet 4 and an inner sheet 1 are folded together, and a folded end paper 2 is glued to the outer right side of the sheet 4. The upper members 13, 13a engage the lift side of the sheet 4 and the right side of the sheet 2 and move them apart, whereafter the lower suction cups 16, 16a engage the left side of the sheet 1 and the inside of the left side of the sheet 2, while the member 30 is set in its left-hand position. Sheet separators.-Sheets are separated in turn from the bottom of a pile 6, Fig. 2, by suction cups 9 on transport rollers 8 rotating clockwise about axes supported on a feeder 5 rotating counterclockwise. Each sheet is thus wrapped round a roller 8 and passed to a gripper 10, so that it is pulled off the roller 8. Sheet forwarders.-On further rotation of the feeder 5, an ejector 11 engages the edge of the sheet and removes it from the gripper, feeding it outside the path of guide rollers 7 on the feeder 5 to rollers 12 which transport it to the opening means.

A filament mount for an electrical device, such as an incandescent lamp, comprises a filament terminated at each end by a wire wound into a coiled section comprising at least one turn, a pair of elongated bridge members having end portions extending into and engaging the coiled end sections and the opposite ends coupled together mechanically by insulating means to form a unit and a pair of lead-in conductors held by a stem and electrically connected to the filament, which support the unit in a predetermined position relative to the stem. In one form, lead-in conductors 16, 18, Fig. 1, extending from a stem press 15 are secured as by welding to the straight ends 24, 25 of a coiled coil filament 22, the ends 27, 29 of two bridge wires 26, 28 being inserted in the ends 24, 25 of the filament and the opposite ends embedded in an insulator 34, which also supports a wire 30 having a hook 32 engaging a bight 23 in the filament 22. The wires 26, 28 are also welded to the lead-in wires 16, 18. In a modification, the ends of the bridge wires are curved outwardly where they engage the end coils of the filament producing a stress which reduces sag. In a further modification, the wires 26b, 28b, Fig. 7, are arranged end to end in the insulator 34b and bent twice at right angles so that the coil engaging ends 27b, 29b are directed towards one another to support a straight filament coil 22b, the centre of which is supported by a wire 30b extending from the insulator. Alternatively, the ends 27b, 29b are bent so as to extend at right angles to the plane of the wires 26b, 28b.

Abstract: 1323228 Hydraulic - brake pressure - loss warning BENDIX CORP 8 Sept 1971 [8 Sept 1970] 41893/71 Heading F2E [Also in Division G1] In a system for indicating loss of pressure from an accumulator in a hydraulic brake system, a warning buzzer or flashing lamp is energized if the rate of change of pressure exceeds a predetermined value during braking. In Fig. 1, the pressure of a nitrogen precharge or the pressure of the hydraulic fluid itself is sensed by a pressure-sensitive transistor or strain gauge bridge circuit. When the brakes are applied, switch 30 opens so that memory 32 stores the then existing pressure, and timer 36 is started. If during the period of the timer the pressure drops below a given percentage of the stored pressure signal a latching relay 40 or S.C.R. is energized. Alternatively, the pressure signal may be differentiated and compared with a reference signal (Fig. 4, not shown).
