Title: Fourdrinier paper making machine
IPC: D21F1/00
Filed: 1953-03-23
Abstract: 725,843. Fourdrinier paper-making machines; wire-changing. BAGLEY & SEWALL CO. March 23, 1953 [March 28, 1952], No. 7897/53. Class 96. Side beams 30 of a Fourdrinier paper-making machine are supported on cross beams 31 &c., bolted down at 42 and resting on pillars 40, wire-changing being effected by raisng jacks 51 so that they first press against spacerblocks 46, allowing removal of smaller, slotted blocks 49, then lowering the jacks 51 so that the blocks 46 may be removed; the breast roll being detached from laminar shake springs and swung downwardly about pivots, inserting the wire-cloth sidewise and replacing the blocks 46, 49. The breast roll is then swung back into position by hydraulic cylinders &c. acting through sheaves and cables. A motor drives separate shake mechanisms for the breast roll and the joints between the side rails and register bars. The suction boxes may be in groups and may be shaken: they may be of metal, with flat tops with longitudinal slits, with screw adjustment 282 at each end, and flexible conduits 290; and they may be removed for resurfacing &c. by lowering them on to rollers 302 of a carriage 298 running on longitudinal rails 300. If the couch roll has a suction pipe at each end, one pipe is doubled back close to the roll so that it is unnecessary to disconnect it for wire-changing. Interlock mechanism and an electric switch prevent operation of the shake whilst the breast roll is disconnected from its supports. One or more take-up rolls may have showers connected to the pipe line through rotatable joints. There may be one wire-cloth guide-roll with manual adjustment and another guide-roll with automatic adjustment. In a modification, mechanical screw-jacks may support the spacer blocks to provide for adjusting the inclination of the machine.

Patent GB-254000-A (GB)
Title: Improvements in automatic and semi-automatic telephone systems
IPC: H04M3/36
Filed: 1925-03-24
Abstract: 254,000. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), and Searle, A. M. March 24, 1925. Automatic exchange systems.-In a hunting switch which if all the outgoing trunks are busy, is arrested upon the last contact set to meter the overflow condition, means are provided whereby if another subscriber having access to the same group of trunks loops during the overflow condition, he is given a busy tone and the operation of the associated hunting switch is prevented. The invention is described as applied to a line switch of the normal type. When the line switch is seized the line relay L grounds the private wire P and energizes the rotary magnet RM, which advances the wipers to an idle line, whereupon the cut-off relay K pulls up in known manner. On release, the relay K relapses and the rotary magnet RM drives the switch to normal under control of wiper H. During a call, a relay associated with the seized trunk closes a point in a chain in the circuit of a relay M, which therefore energizes when all the trunks are busy and removes ground from the test contacts in the twenty-fourth or last position of the line switches. The line switch of the next subscriber instituting a call will stop in this position, busy tone will be sent over the negative contact, and a relay A will energize over the calling loop and close a circuit for a relay B. Relay B meters the overflows over armature 11, replaces ground on the test contact to hold up the cut-off relay K after the relapse of the line relay, and substitutes busy tone for ground on the common conductor leading from armature 9 so that if another subscriber calls he will receive busy tone over his positive line, and his line relay will not operate. When the first subscriber hangs up, relays A.B , relapse and the switch returns to normal position. Any other parties who may be attempting to seize an outgoing trunk will now meter these attempts in succession. When a trunk falls free while a switch is on the last contact set. the relay M relapses, removes ground from the test contact, and causes the relapse of relay K, wherebv the line relay L energizes and causes the switch to hunt for the idle line.

Abstract: 526,309. Making levers and linkwork. FLOWER, A. March 13, 1939, No. 7993. [Class 83 (ii)] [Also in Groups XXIV and XXVI] Levers, links, rods &c. particularly valverocker arms and connecting-rods, are formed from two complementary sheet-metal pressings with a flat intermediate sheet-metal member between them, the pressings being shaped to engage the intermediate member along its edges and between its edges and welded thereto at the three lines of engagement. Two complementary parts 11 of a connecting-rod have each an inwardly pressed part 15, Fig. 3, and are welded along their edges and along the parts 15 to a flat sheet-metal member 12, thus providing a quadruple-closed hollow section. The small end comprises a split sleeve 16 with lugs 16a and against, which bear inwardly directed flanges 17, 18, Fig. 5, of openings in the parts 11, the flange 17 being narrower than 18 to provide room for a flange 19 on the member 12. The flanges are welded to the sleeve. The pressings and the member 12 are split at 21 in line with the slit in the sleeve and blocks 22 are welded to the pressings, the member 12 and the lugs to receive a grub screw. The sleeve 16 may be continuous. The big-end comprises two semi-cylindrical sleeve portions 23, 24. The portion 23 has, welded against its outer periphery, a channel-section sheet-steel pressing 25 which is welded to a flange 26 at the end of the intermediate member 12, the adjacent ends of the pressings 11 being welded to the flanges 28. At the ends of the pressing 25 are welded blocks 29, the pressings being bent over the blocks at 30. The cap is substantially similar and has welded to the part 24 a channelled sheet-metal pressing 32, Fig. 2, the flanges of which are deeper than those of the pressing 25, and which has blocks 23 welded to the ends thereof. For lubricating and cooling purposes, a pipe may be carried by one of the closed sections of the rod, or the fluid conveyed along one of the sections. The only parts to require machining should be the sleeve portions 23, 24 and the mating faces of the lugs 35.
