Title: Improvements in guiding mechanisms for travelling webs
IPC: D21F1/36
Filed: 1956-09-14
Abstract: 840,929. Guiding webs transversely. FIFE, I. L. Sept. 14, 1956, No. 28173/56. Class 100(1) In a web guiding mechanism for a travelling web, a lateral change in path of travel of the web, to restore the web to a desired lateral path as a result of a lateral deviation from its path, is caused by a lateral and angular change of position of a guide roller or rollers about which the web is wrapped, a support being provided at each side of the web for the ends of the roller or rollers and each support is slidable in a separate set track and wherein the setting of the tracks can be changed so as to vary the relationship between the lateral movement and angular movement of the roller or rollers with respect to the web. As shown, the web D passes around rollers 10, 12 mounted in frames A each having identical L-shaped brackets 1 and 2 having vertical portions 3 and 4 and horizontal portions 5 and 6 respectively. The portions 3,4 support a shaft carrying the roller 12, while the portions 5, 6 support a shaft 9 carrying the roller 10. The portions 5, 6 have hubs 7, 8'which receive vertical spindles 28, 48 respectively such that the portions 5, 6 can pivot about these spindles. The spindles 28, 48 are threaded into blocks 27, 47 slidable along pairs of rods 25, 26 and 45,46 respectively. The rods 25, 26 are mounted on a plate 20, while the rods 45, 46 are mounted on a plate 40. The block 47 has a threaded bore which receives a screwed shaft 53 secured against axial movement, but rotatable by a pulley 57 and endless belt 58 passing around a driving pulley 88 on a shaft 86. The shaft 86 is driven by a power unit in response to lateral deviations of the web 10 as detected by a sensing member 80. The sensing member 80 has apertures which are covered or uncovered upon lateral movement of the web to vary the pressure exerted on a diaphragm within a unit 70 having a constantly driven cone movable by a lever actuated by the diaphragm into engagement with a pair of cones on the shaft 86 to rotate the shaft 86 in either direction. Since the plates 20 and 40 are inclined to the direction of web travel, deviations of the web from its predetermined path cause tilting of the rollers 10 and 12 as well as lateral movement of these rollers with respect to the direction of web travel, thereby returning the web to its predetermined path.

Patent GB-922323-A (GB)
Title: Position control apparatus
IPC: G05B19/23
Filed: 1961-08-03
Abstract: 922,323. Digital control of machine tools. WESTINGHOUSE ELECTRIC CORPORATION. Aug. 3, 1961 [Sept. 6, 1960], No. 28252/61. Class 40(1). An apparatus for controlling, for example, a machine tool to bring it to a desired position comprises a motor 14 which drives both the tool 16 and a transducer 10. The transducer outputs pass positive or negative feed-back signals to amplifiers 18, 22 which therefore either oscillate or do not oscillate. The transducer is so designed that movement of the machine tool causes negative and positive feed-back signals alternately to be applied to each amplifier, the transition from positive to negative feed-back not occurring at the same time in both feed-back paths. The amplifier outputs therefore consist of two phase displaced trains of A.C. pulses when the tool 16 is moved. The pulses are converted to D.C. pulses at 26, 28 and pass to a detector 30 which gives an output indicative of the presence or absence of the D.C. pulses and their relative phase. A reversible counter 32 monitors the pulses and feeds a comparator 34 which is also fed with a count indicative of the desired position of the machine tool. The difference is converted to an error signal by unit 38 which controls the motor to correct the position of the tool.

Abstract: 924,153. Pallets for handling loads. L. DAVIDSON. Aug. 18, 1959, No. 28266/59. Class 78 (4). The legs 17, Fig. 1, of a cardboard pallet 15, are formed by cutting along sides 18, 19, 20 and folding the portion 17 downwardly along score marks 21 and upwardly along score marks 24, whilst recesses 26 accommodate the ends of the side 19 when the leg is folded into operative position. As described, the leg portions may be cut from a lower layer 34 of a laminated pallet 15, Fig. 2, the upper layer 32 being added later. The top layer 32 may be dispensed with, in which case the side 19 is held in the recess 26 by friction or adhesive. As shown in Fig. 5, the free end of a leg 37, which is cut from the lowest of three layers 44, 46, 48, is held in position by being inserted into an undercut region 58. The leg portion may be reinforced by material cut from the middle layer of the pallet. Fig. 8 shows how a leg 87 may be cut from a single layer of cardboard, a side 89 being cut with recesses 98 which engage with recesses 96. Tabs 99 folded along score marks 100 may be provided. The bottom of a leg 124, Fig. 11, may be formed by cutting and crushing some of the laminations over an area 134, crushed material may be removed or left in place. A leg 125 is formed by making a cut 144 through some of the laminations of the board. A leg 126 is formed by crushing the laminations without cutting any of them. Each leg has a tab 138, formed by crushing all the laminations, which rests on the upper surface of the pallet. All the legs described may be formed with one portion vertical and the other portion at an angle thereto. A leg 156, Fig. 17, is cut with tabs 164 which pass through holes 174 and lie on the surface of the pallet. Recesses 168 may be elongated to include the holes 174 or alternatively the holes 174 may be offset from the recesses 168. The edge 170 extends through the pallet and is in direct contact with the load thereon. A hinge for a leg may be formed by making a cut 186, Fig. 24 in the pallet 184. Alternatively, several parallel cuts may be made having cross-cuts at right angles between them.
