Title: Improvements in or relating to the continuous production of envelopes, bags, pouchesand the like
Inventor: BONSOR DAVID VICTOR
IPC: B31B19/00
Filed: 1956-02-06
Abstract: 836,003. Making envelopes, pouches &c. DICKINSON & CO. Ltd., J. Jan 24, 1957 [Feb. 6, 1956], No. 3623/56. Classes 94(2) and 133. [Also in Group XVI] In apparatus for providing a bulked fold in envelopes, pouches, &c. transverse to the direction of travel through the forming machine, the blank is passed over a roller A having a projection which deflects its leading portion, an element applying pressure at the line of fold and the fold being consolidated by a further roller C co-operating with the roller A. In one embodiment the roller A has gaps 10, 11 faced on their trailing sides with plates 12<SP>1</SP> which project above the roller periphery to act as deflectors. A strip 14 on a shaft 15 presses each blank 16 behind its deflected flap 17 to delineate the fold which is completed by passage of the envelope between the rollers A, C. The roller C has a gap 18 to prevent sharp creasing of the fold. The roller A has rows of suction apertures 13 behind each plate 12<SP>1</SP> to retain the blank against it. In another embodiment, Fig. 3 (not shown), the strip 14 is replaced by a roller having section apertures by which it pulls the portion to be folded upwards and a gap providing a fold delineating edge. In a further embodiment, the strip 14 co-operates with recesses in the roller A, the latter having several rows 13 of suction apertures behind each recess.

The sections in flat development, may be rhomboidal and laid preferably with their abutting ends paralle with the axis of the tunnel, or rectangular with their abutting ends inclined to the axis of the tunnel or they may comprise substantially rectangular blocks 1 with lips 7 at opposite ends of opposite sides. The length of the sections may be such that in adjacent circumferential runs the sections break joint. Specification 564,643 is referred to.

Abstract: 354,706. Electroplating. DEHN, F. B., 103, Kingsway, London.-(Major Engineering Corporation; 123, West Madison Street, Chicago, U.S.A.) Feb. 7, 1930, No. 4259. [Class 41.] On the bottom of a plating tank having movable cathodes is placed a layer of a pulverulent soluble metal, which replenishes the solution and becomes partly disseminated through the electrolyte so as to depolarize and burnish the cathodes. In soluble anodes are used. The cathodes are hung from a continuous travelling band 27 which passes round pulleys 13 .. 16 at the ends of the tank and, between the pulleys 15, 16, travels to and from a pulley 21. A screw adjustment 22 is provided for the bearing block of the pulley 21, for tightening the band. The band is supported by a flange on each pulley and is also secured to T-shaped shoes 28, Fig. 5, which slide in trackways 30 .. 33.

Title: Improvements in or relating to apparatus for the reception of modulated oscillations
IPC: G01S7/36
Filed: 1941-03-31
Abstract: 587,562. Wireless receiving circuits. BLUMLEIN, A. D. March 31, 1941, No. 4321. [Class 40(v)] Apparatus for reducing interference by undesired oscillations modulated at a relatively low frequency superimposed upon desired oscillations modulated at a relatively high frequency includes a limiter, the limiting level of which is. controlled solely by the undesired oscillations which are separated from the desired signal after detection. Fig. 2 shows a circuit for receiving pulse signals for obstacle detection which are subject to jamming by a carrier which may be unmodulated or modulated at a low frequency. The signal is fed by a transformer 20a to the last intermediate frequency amplifier 6 and thence via transformer 14 to detector 7, the desired pulses being taken from an output circuit 8, 9 of short time constant. A part of the output from detector 7 is fed through resistance 10 to a D.C. amplifier 12 normally biassed to cut-off. A condenser 11 byepasses pulse frequency energy. The anode of valve 12 is connected through resistances 19, 20 to a negative voltage so that the junction point of the resistances provides a voltage suitable for biassing to cut-off the grid of the I.F. valve 6 on the occurrence of a predetermined amount of interference, leaving only those parts of the pulses which are super. imposed on the positive peaks of interference. In an alternative arrangement for rendering the D.C. amplifier inoperative for pulse frequency energy, valve 12 is a hexode having its control grids connected to spaced tapping points on a terminated delay network. In which case pulses would not give the necessary simultaneous potential on both - grids. In Fig. 3, the D.C. amplifier is dispensed with and the last I.F. valve 6 receives additional grid bias by partial rectification from the lower end of resistance 24 fed from resistance 23 in the anode circuit. The time constant of resistance 23 and condensers 25, 21 is small so that only a persistent increase in anode current increases the grid bias to cut-off to limit the interference and' leave the pulses. In a similar arrangement, Fig. 4 (not shown), the bias is obtained from a resistance in the cathode circuit. Due to changing phase relationships between the pulse oscillations and the interference, the output pulses may in some cases be negative. A network is then necessary to eliminate the negative pulses if the output is to be applied to integrating arrangements such as are described in Specifications 577,275 and 585,907.
