Patent GB-357134-A (GB)
Title: Switching on electric wave signal transmission systems
IPC: H04B3/20
Filed: 1930-06-13
Abstract: 357,134. Two-way repeaters. STANDARD TELEPHONES & CABLES, Ltd., GROVE, S. H., and HODGSON, K. G., Columbia House, Aldwych, London. June 13, 1930, No. 18158. [Class 40 (iv).] Two-way repeaters are normally conditioned for transmission in the two directions alternately by pulses of tone current sent alternately in opposite directions from one end of the system to the other. When speech takes place the alternations are sunpended and the repeaters are continuously conditioned for the direction required. The Figure shows a terminal station A connected over cables CW, CE, and one or more intermediate stations C to a distant terminal station similar to A. When a tone pulse from the distant station arrives at C, relay S21 responds energizing the right-hand winding of polarized relay Q so that relays S22, S23 close the west-east branch TB1 and relays S24, S25 open the east-west branch TR1. Part of the tone pulse also passes on to the terminal station A at which relay S4 operates for the duration of the pulse and causes relay S1 to transmit a pulse from source T over the system in the opposite direction. At the intermediate station C polarized relay Q is now operated in the opposite direction to open path TB1 and close path TR1. When speech arrives at A from line L1 relay S7 energizes and provided that a pulse is not being received by relay S4, relay S8 operates and disconnects source T. When the next pulse arrives at A, relays S1, S2, S3 are locked by relay S5, the path TB being switched through and the path TR opened. A delay network D1 delays the speech currents for a time sufficient for the above operations which in the extreme case in which a pulse is being received when relay S7 operates will be twice the transmission time of the pulses over the cable. Means may be provided controlled by relays S4, S8, whereby a smaller delay network is used when the position of the tone pulse at the instant when speech is initiated is such that less delay is required, and further changes in the amount of delay in accordance with requirements may be provided by the use of relays with different operating times. With such arrangements, a different equalizer E1 may be used with each delay network.

Title: Improvements in or connected with machines for folding paper
IPC: B65H45/18
Filed: 1934-06-21
Abstract: 440,201. Folding paper. DRAPER, W. H., Winterfield, Paulton, Bristol. June 21, 1934, No. 18326. [Class 100 (i)] A paper-folding machine of the kind in which the sheets to be folded are conveyed to the separate folding devices by means of a tape feed is constructed so that it can be readily adapted for folding papers of different kinds e.g. thick and thin papers, with accuracy. The tape-feed associated with the first folding device is driven by a change speed device, and the other tape-feeds are driven by a constant drive, thus permitting the initial feed for thin papers to be slower than for thick papers. In a machine which is formed of five folding devices of the reciprocating- blade type, the sheets are fed in succession by tapes T<1> to either a first folding device I, or to a similar folding device III. From the first folding device I tapes T<2> carry the sheet to a second folding device 11 which produces a fold at right angles to the first fold and the fourth folding device IV receives either a once folded sheet from the device I or a twice folded sheet from the device II. The device IV forms a fold parallel to the fold produced by either II or III, and a subsequent parallel fold may be produced by the folding device V. The shaft S of the tapes T<1> is driven from the main shaft D, which drives the folding devices by chains C<1>, C<2>, and by a shaft D<1> and chains C<3>, C<4>, C<5>. Two sprockets H, H<1> Fig. 5, are mounted on the shaft D and drive sprockets H<2>, H<3> freely mounted on the shaft S of the drum T which drives the first tapes T<1>. The sprockets H<2>, H<3> are integral with flanges L<2>, L<3> which can be connected by a screw bolt N to a flange L, or L<1> respectively, fixed on the shaft S, which can thus be driven at one speed by the sprocket H<1>, or at a slower speed by the sprocket H. A gear K on the sleeve L<3> drives constantly the feed roller which feeds the sheets to the tapes T<1> at a constant speed. The folding devices and their blades and registering devices R are of usual construction, and any of them can be put out of action if desired. Also folders of the buckling type may replace some of the reciprocating blade folders shown.

Filed: 1917-12-15
Abstract: 129,741. Cooper, J. D., (Representative of Cooper, B. G.), and Griffiths, E. A. Dec. 15,1917. I n d i c a t i n g by thermostatic devices.- The level of a liquid is indicated bv measuring the resistance of an electrically heated wire partly immersed in the liquid. The temperature of the part of the wire outside the liquid being higher than that of the part immersed, since the liquid absorbs heat more quickly than the vapour or air above it, the resistance of the wire varies with the liquid level. The wire may be insulated by oxidizing or enamelling it. The platinum or like wire A, B placed in a liquid forms one arm of a wheatstone bridge A, B, D, G, E, C. A fine iron wire resistance J is inserted in the battery circuit so as to maintain an approximately constant current. External variations of temperature are nullified by placing in the opposite arms of the bridge a similar platinum wire kept out of contact with the liquid by a tube K.

Abstract: 1,061,129. Valves. GRINNELL CORPORATION. May 5, 1965 [May 14, 1964], No. 18909/65. Heading F2V. A diaphragm valve, Figs. 2 to 6 (not shown), is of the type in which the diaphragm seats on a cylindrical side wall of the flow passage in closed position. The diaphragm is moulded in such a shape that a layer of flexible reinforcement fabric 11 embedded therein takes up a position whereby stressing of this reinforcement in use is reduced. The diaphragm has an outer rim 82 of greater width than thickness, joined to a solid central portion 74 by an intermediate portion 81 of which the opposite sides are parallel. In the undeformed shape as shown, the intermediate portion turns sharply away from the surface 78 of the central portion at a juncture 100, turns abruptly back upon itself at a bend spaced radially outwardly from the juncture 100, and turns abruptly into the rim 82 at a juncture 96. The reinforcement fabric has taken up a position substantially closer to the top surface of the intermediate portion than to the bottom surface at the two junctures 96, 100, and is substantially closer to the bottom surface of the intermediate portion than to the top surface at the bend 98. A member 15 for connection to an actuator is embedded in the diaphragm. In the closed position of the valve, the deformed diaphragm still preserves a shape similar to that of the undeformed state. In a modification, Fig. 7 (not shown), the diaphragm has a facing of hard plastics material (156) on a backing of resilient material which contains the reinforcement.
