Title: Apparatus for opening a lap or fleece of fibrous material
IPC: D01G9/00
Filed: 1958-11-11
Abstract: 910,187. Opening fibrous material. FLEISSNER G.m.b.H. Nov. 11, 1958 [March 19, 1958; April 9, 1958], No. 36191/58. Class 120 (1). Apparatus for opening long-stapled or shortstapled fibrous material comprises material feeding means adapted to feed the material through the nip between gripping rollers and partly around selectively either a larger gripping roller on to an opening drum or around a smaller gripping roller on to the opening drum, the distance of the nip in the path of the material from the opening drum being less for the smaller gripping roller than for the larger gripping roller. In the embodiment shown in Fig. 1 a carriage 1 provided with a first pair of gripping rollers 3 and a second pair of gripping rollers 4 is positioned between conventional conveyer means 10 and opening drum 2. The carriage can be moved in direction of arrow 17 by hand wheel 5 so as to selectively interpose either pair of gripping rollers between the conveyer 10 and drum 2 depending on whether long-stapled or short-stapled fibrous material is to be processed. In a second embodiment (Fig. 2) a rotary conveyer 10A is used and there is provided a fixed gripping roller 21 and a disc 22 pivoted at A and carrying a large-diameter gripping roller 24 and a smaller one 23 such that either one or other can be brought into engagement with roller 21 depending on whether long-stapled or short-stapled fibrous material is to be processed. In a third embodiment a pair of gripping rollers one of large diameter and the other small diameter is provided and the drum 2 is rotated in the forward or reverse direction depending on whether long or short stapled material is to be processed.

Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1953-12-30
Abstract: 740,302. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 30, 1953 [Dec. 31, 1952], No. 36192/53. Class 40 (4). In the event of the subscriber's loop remaining closed after the breaking down of a connection to him, the hold magnet of the primary cross-bar switch over which he is connected is held energized over a cross point of the switch and the subscriber's loop. This condition may occur, either through a subscriber neglecting to hang. up after a call, or through timed release, or through the action of an operator. As shown, Fig. 1, connection to a link circuit SN is established over primary and secondary cross-bar switches SLA, SLB through an operation involving select magnets SA, SB and hold magnets MB respectively, the secondary cross-bar switch operating first to bring up relay R which brings up the corresponding hold magnet MA. When the link circuit SN is released, switch SLB releases followed by R which completes a holding circuit for magnet MA over the switch SLA and the subscriber's loop. Alarm relay AL operates and injects tone from a source Su into the lower winding of MA for transmission to the subscriber. In a modification, Fig. 2 (not shown) in which the trunking is such that both the hold magnets are associated with the link between the primary and secondary stages, the functions of relay R are performed by the secondary hold magnet. In a further embodiment, Fig. 4A, the holding circuit for the primary hold magnet is completed over a gasfilled tube G. The connection is set up as before, the potential connected to the cathode of the tube G over the contact C2 being sufficiently high to prevent the striking of the tube at this stage. The connection is held by relay R2 in the link but may be broken down by the application of potential to the wire d to operate R1 thereby releasing the hold magnet MB of the switch SLB. Tube G now receives striking potential from the source -U1 over the magnet MA which is thus held over the tube G, the subscriber's loop and the rectifier e1. Rectifier e3 also conducts-now to bring up the alarm relay AL and tone is reverted to the subscriber as previously described. In a modification, Fig. 4B (not shown), the striking voltage for the tube is provided from the link circuit immediately before the release of the secondary switch. In a further modification, Fig. 3 (not shown), the tube G is replaced by a rectifier.

Preferably a punched-out tab 72 or equivalent formation (90, Fig. 8, not shown) is arranged opposite the or each kerf-engaging flange at each of a number, e.g. three, of positions along the stud to give additional support to the panels in said one row at heights where such additional support is desirable, e.g. at heights of three foot; three foot, eight inches; and four foot, four inches. The joins between panels in the two rows may be staggered, as shown in Fig. 2, or may be substantially opposite each other (Fig. 5, not shown) in which case the webs of the juxtaposed studs whose flanges are engaged with the kerfs of the panels in the two respective rows may be secured together. The form of stud 60a shown in Fig. 6 and having only a single flange 68a is used where it is desired to remove one panel 40a in one row without disturbing adjacent panels 40a in the same row. Preferably studs having two flanges are used for the other row of panels for security reasons. Alternatively, adjacent pairs of studs 60a engaged with the kerfs in one row may be secured together by screws (110, Fig. 11 not shown). The stud shown in Fig. 6 may be modified (Figs. 8-10, not shown). To ensure that the panels 40 abut and hide the studs the vertical edges of the panels are inclined away from each other from the front to the back of each panel. Where pairs of studs 60a are used, trim members (100, Fig. 11, not shown) may be inserted between the adjacent panel vertical edges. The top and bottom edges of the panels are mounted to conventional ceiling and floor runners 28, 26, the former providing channels to receive the top edges and the latter being adapted to receive screws for fastening the lower edges, the screw heads being then covered by base clips or members (32 or 34, Fig. 1, not shown).
