Filed: 1972-08-15
Abstract: 1352096 Film stretching apparatus HERMANN BERSTORFF MASCHINENBAU GmbH 15 Aug 1972 [25 Aug 1971] 38039/72 Heading B5B Stretching apparatus for films comprises two trains of freely rotatable stretching rolls 1 and 2; rolls 2 are stationarily mounted but rolls 1 are movable together, in the direction of the arrows shown thereon, towards and away from rolls 2. In operation, with rolls 1 in the loading position of Fig. 1 a film 3 of plastics material is introduced downwardly between rolls 1 and 2. Stretching rolls 1 are then moved to the right to the operating position of Fig. 2, in which the stretching rolls are driven by the film itself which is pulled out of the train of rolls by driven rollers not shown. Heating of the rolls prior to stretching is effected in known manner, but during heating the rolls 1 and 2 are kept in motion by belt drives 14 and 15; this eliminates thermal distortion and consequent asymmetry of the rolls which occurs when the rolls are heated while stationary. Rotary movement of rolls 1 and 2 is also maintained in the event of film breakage; in this event rolls 1 are moved leftwardly to the Fig. 1 position to allow the new end of the film to fall through the stretching equipment under its own weight. But to prevent the rotation of the stretching rolls from stopping, rolls 1 are moved against the part of the belt 8 supported by supporting rollers 13 which in such event is set in motion automatically by means of a limit switch, not shown, which energizes the driving and tension roller 7 to move the belt 8 and so rotate rolls 1. Simultaneously, driving and tension roller 5 is energized and belt drive 14 which can be moved towards or away from the rolls 2 in the direction of the arrows 11 is moved leftwardly to cause the portion of V-belt 9 supported by support rollers 12 to engage stretching rollers 2 and rotate them.

Title: Nut and panel assembly and method of making same
IPC: F16B37/04
Filed: 1962-10-10
Abstract: 991,487. Anchor-nuts. MULTIFASTENER CORPORATION. Oct. 10, 1962 [Oct. 10, 1961; Nov. 28, 1961], No. 38298/62. Heading F2H. [Also in Division B3] A pilot portion 22, Fig. 2, of a nut 21 punches a hole in a panel 20 and is secured in the hole by the displacement of panel metal, Fig. 3 (not shown), into a nut groove 28 by a die 35. The nut 21 is elongated so as to have shoulders 27 on to which the panel is forced and its width, Fig. 11, corresponds to that of the pilot portion 22. Two parallel grooves 28 are formed across its length and while ridges 40 on the die 35 force panel metal into these grooves, two opposite edges 44 of a die aperture 36 force down two edges 25 of the pilot surface 23 to close towards the grooves. At the same time, surfaces 134, Fig. 10 (not shown), of die ridges 135 at right angles to the ridges 40, compress two edges of the panel hole, Fig. 11, and depress two edges of the pilot surface 23 so that they bulge against the hole edges at the undersurface of the panel 20. In a modified form, Figs. 12, 13 (not shown), larger ridges 135 are formed on the die to depress edges of the panel hole. In a modification, Fig. 4, of the aspect of Fig. 2, the grooves are of rectangular section with an outer overhanging peripheral ledge 50 and the parallel edges 65 of the die aperture 56 are each the lower edge of an inclined surface which pushes out, over the panel metal forced into a groove 45 by a die ridge 59, the edge of the pilot portion 41 sliced out by the aperture edge. In a similar modification, Figs. 6, 7 (not shown), inclined walls replace most of the vertical walls of the grooves so that they taper downwardly in section and the two die aperture edges slice into the inclined sides of the pilot portion of the nut to stake a portion over into each groove. This modification also differs from that of Fig. 4 in that the two die surfaces inclining from the two aperture edges are the tops of large die ridges. In another form, Fig. 8, in which the pilot portion is not deformed, a rib 108 bounds the outer face of each groove 105 and an inclined face 121 of a die ridge 123, by way of the panel metal, turns the rib over its groove, the ridge also forcing panel metal into a small nut groove 111. In Fig. 17, two opposite sides of the nut pilot portion 205 are undercut to form grooves 206 under two of its edges and the other two edges of the pilot portion are sliced by the die edges 226 so that they are staked out, Fig. 18 (not shown), over the edge of the panel hole punched by the pilot portion. In another form, Figs. 19-22 (not shown), a groove, similar in section to those shown in Fig. 4, forms a square around the pilot portion which is central of a square nut while the die has four ridges and aperture edges similar to the two shown in Fig. 4. Alternatively the nut pilot portion and die ridge pattern &c. may be of hexagonal or circular form. Various sequences of vertical movements of the nut, panel and die are described.

Abstract: 1,024,338. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 22, 1964 [Sept. 23, 1963], No. 38522/64. Heading H4K. The time slots of pulses gating a channel over a time division multiplex system are shuffled from one cycle to the next so as to render unintelligible the cross-talk which would exist between channels using invariable time slots. In a system having a synchronizing channel O and twelve time slots for channels 1 to 12, Fig. 1a shows the fixed adjacency of channels accorded invariable time slots. As shown in Fig. 1b time slots are shuffled according to a scheme in which the " odd and even" time slot pairs of a cycle are interchanged to produce the pattern of the next cycle, the end time slots of that next cycle being left undisturbed while the " even and odd" pairs are interchanged to produce the pattern for the following cycle, and so on. Where a line identity is stored in parallel in a circulating delay line system VS, Fig. 4, the delay lines having a delay time of T - T, T being a time slot cycle and # being the width of a time slot, the line identity can be recirculated via gates Sf to be advanced one time slot in the cycle, or it can be recirculated via a delay of # and gates Sn to maintain its position, or it can be recirculated via a delay of 2# and gates Ss to be delayed by one time slot in the cycle. The pulses s, n, f, necessary to effect the shuffling referred to above, are produced by a circuit BG described in detail with reference to Figs. 5 and 6, not shown. By use of tappings on a magnetostrictive delay time at points T - #, T, and T + #, the channels may be shuffled in the same way. With this arrangement, and in combination with a series to parallel converter, the line identity may be circulated serially. Since the shuffling process interferes with the frequency of operation of the line gates these gates may all be operated at the time slot P 0  to control in accordance with speech level a storage device which is gated to the highway by pulses in the shuffled time slots. Where line identity is stored in a magnetic cored matrix read out to control the line gate under control of an access register, the accessing may be done at random to produce the shuffling.
