Title: Improvements in machines for interfolding paper
IPC: B65H45/24
Filed: 1947-11-10
Abstract: 656,527. Folding paper. BURGESS, A. F. (International Cellucotton Products Co.). Nov. 10, 1947, No. 29882. [Class 100 (i)] An interfolding machine, especially for interfolding and stacking flimsy paper sheets such as facial tissue, comprises a pair of oppositely rotatable cylinders each having alternately disposed sets of gripping jaws and movable tuckers, the tuckers or sets of jaws of one cylinder co-operating respectively with the sets of jaws or tuckers of the other cylinder in timed relation, the cylinders having a shaft rotatably mounted in a sleeve secured to a frame of the machine and extending inwardly of the frame toward the cylinder, the sleeve having an external cam surface for actuating movable jaws of the sets of jaws and a second cam surrounding the sleeve having an internal cam surface for actuating the tuckers in timed relation to the movable jaws. Interfolding cylinders 12 and 13 supported on stub shafts 17 carry alternately-spaced movable jaws 40 and tuckers 26 so that the tuckers on one cylinder co-operate with the jaws on the other cylinder. The stub shafts 17 are mounted in bearings 19 within sleeves 20 carrying cams 21 co-operating with followers 45 carried by cranks 44 which actuate the jaws 40 against springs 46. The sleeves 20 are adjustably secured to frame members by clamping-screws 24 passing through slots 23 in the sleeves so as to vary the timing of the cams 21. The tuckers 26 formed with blades 27 are inwardly movable in slots 25 against springs 29 by followers 36 which engage internal cams 37 formed in housings 51 adjustably secured to frame members by screws 53 passing through slots 54 in the housings. The cylinders 12 and 13 are driven through spur gears keyed to the shafts 17. Stripper and stacking members 34 formed with blades 60 are associated with each of the cylinders and are actuated alternately by shafts 58 each rotated by a crank-wheel 62 adjustably secured to cranks 63 driven by a connecting rod 64 driven by a gear 66. Sheets 10 and 11 cut from webs in a staggered fashion are fed by feed rollers 14 to the cylinders 12 and 13, a tucker 26 on one cylinder engaging the sheets to fold them in between a pair of opposing open jaws 40 and 41. The movable jaws 40 close to grip the folded sheets which are stripped from the jaws 40 and 41 when they are again opened. The sheets are stacked by the members 34 to form a pile 61. The gripping faces of the jaws 40 and 41 when closed are non-radially disposed with respect to the cylinder in which they are mounted, and the bisector of the angle between the tucker faces is also non-radial. The planes bisecting the angles between cooperating jaw faces and tucker faces extend during the gripping operation, as shown in Fig. 7, on opposite sides of the axes of the cylinders and are in approximate coincidence when the co-operating tucker and jaw are at their point of closest approach. Such non- radial disposition of the tucker and jaw faces facilitates gripping of the paper and withdrawal of the paper from a set of jaws.

Title: Improvements in and relating to an electrolytic process for the hydrogenation of carbonaceous material
IPC: C10G1/06
Filed: 1935-11-01
Abstract: 466,708. Electrolytic hydrogenation of carbonaceous materials. THOMAS, W., and DAVIES, E. L. Nov. 1, 1935, No. 30240. [Class 41] Carbonaceous material is hydrogenated in a cell the electrodes of which are separated by a partition comprising trough elements 39, the lower part of each of which lies below the upper part of the element next below it this arrangement permitting passage of the current and of the electrclyte but hindering passage of the products of electrolysis. In the apparatus shown the troughs are arranged in inclined columns between a tapered anode 35 and inclined cathode members 33. Electrolyte is supplied by a conduit 44 and cathodic and anodic products are drawn off by conduits 46, 47 respectively. Carbonaceous material is supplied to the cathode space by a conduit at the top (not shown), or may be supplied by the conduit 46 in counter-current to the electrolyte outflow; it is detained in the cathode zone by metallic bristles 34 projecting from the cathode. The cell comprises top and bottom plates 27, 28 separated by interlocking walls 29 insulated at 31 and secured by bolts 30. The elements 39 are provided with downwardly directed flange members 42 serving to hinder entry of the carbonaceous material into the partitions ; the flange members are provided near the top with apertures 43 to prevent the collection of pockets of gas. The ends of the trough elements are housed in side channels and the elements are provided with distance pieces either separate or integral therewith. They may be formed of the material known by the Registered Trade Mark " Pyrex," Jena glass, porcelain, ceramic material or enamelled metal; bare metal may be used when the inter-electrode potential is not greater than 3 volts. Porous material such as glass wool, asbestos fibre or sand may be inserted within the passages. The troughs may be constituted by pairs of spaced members; in a modification these members are secured at the inside to a pair of perforated plates. In a modified apparatus the cathode and partition -are conical. The apparatus may be maintained under high pressure and a flow of electrolyte induced therethrough by hydraulic accumulators adjusted to maintain equal pressures on both sides of the partitions, e.g. in the manner described in Specification 412,646. The hydraulic accumulators may also control the introduction of carbonaceous material and the removal of products. The electrolyte may consist of sulphuric acid of strength 5-30 per cent, or of a solution of equal parts of sodium sulphate and sulphuric acid, or of sodium hydroxide alone or together with sodium sulphate or sodium chloride. The carbonaceous material treated may be powdered coal alone or mixed with oil, sawdust or fish meal. The electrolyte may be heated before introduction into the cell or the apparatus may be heated electrically either internally or externally or may be contained within a furnace chamber or immersed within a bath of molten lead.

Abstract: 665,274. Anti-side-tone circuits. STANDARD TELEPHONES & CABLES, Ltd. Nov. 18, 1949 [Nov. 22, 1948], No. 30248/48. Class 40 (iv). Sub-station sets make use of saturable reactors as voice operated switches. A receiver Rec, Fig. 3, is normally operative but when the sound received by a transmitter Tm exceeds a predetermined threshold level, a rectifier bridge BR1 applies direct current to the control windings A1, A2 of saturable reactors MSR1, MSR2 to reduce the impedance of the controlled windings B1, B2. B2 then has a large shunting effect on the receiver Rec, which becomes inoperative, and B1 increases the coupling between the transmitter and line. A modification, Fig. 8, includes a line balancing impedance X, the transmitter and receiver being in series and shunt respectively with the saturable reactors MSR1, MSR2. A low residual side tone exists. In Fig. 9, the line balancing impedance is replaced by a rectifier bridge BR2 which also feeds the saturable reactor, so reducing the power taken directly from the transmitter. Fig. 13 shows a 4- wire system, the output of a transmitter, before amplification, controlling the impedances of both outgoing and incoming circuits. Fig. 14 shows a 2-way radio link system in which receiver and transmitter are connected to a desk set and then by a 2-wire line to a hybrid circuit, the outgoing side of the 4-wire circuit leading through an echo-suppressor type voicooperated switch VOS to a radio sender and the return side of the 4-wire circuit coming from a radio receiver.

The oscillators 31, 32 are also associated with further loops including amplifiers 44, 53 respectively for automatically re-aligning the comparator 41, 51 outputs to almost zero value thus eliminating residual noise. Other supplementary oscillators (not shown), may be controlled by the control voltage applied to the first oscillator to produce other frequencies differing from the main frequency by different increments, Where the frequency difference is large initially, a further phase lock loop including frequency dividers 54, 55, a phase comparator 56 is used for the synchronization of oscillator 32. The embodiment of Fig. 1 (not shown), includes provision for disabling the second loop each time the second oscillator loses lock and for repeating the synchronization steps in respect of oscillator 31. In Fig. 3 (not shown), which is a modification of Fig. 2, the second oscillator is associated with a single loop including a proportional integrator.

Hydraulic pressure is fed to enclosure 25 during service braking when the pedal 58 of a service brake application control device 12 is depressed and pressure in the enclosure 25 acts to move the third piston 23 in the brake actuating direction and also acts in opposition to the spring 31 through the second piston 22 and the first piston 18. The pressure in enclosures 21 24 is controlled by a hand operated spool valve 38. The valve 38 has ports 46, 49 connected to a reservoir, ports 47, 48 connected to an accumulator and outlet ports 36, 37 connected respectively to enclosures 24, 21. In the inoperative position 55 of a hand lever 13 of the spool valve 38 ports 49, 36 are connected and ports 47, 37 are connected. When the vehicle is stopped temporarily the driver moves hand lever 13 to a central position so that liquid under pressure is now fed from the accumulator through the spool valve to the enclosure 24 as well as enclosure 21, and pistons 22, 23 are moved together in a brake actuating direction; and the brake is held actuated by holding of the hand lever 13 mechanically in the central position. Should the driver wish to apply the hand brake for parking, he moves the hand lever 13 to a third position 57 whereby ports 37, 36 are connected to the liquid reservoir to vent enclosures 21, 24. The coil spring 31 expands to move pistons 18, 22, 23 to apply the brake. The spring 31 acts on piston 18 via a probe 33 on a top hat section reaction member 32 and piston 18 acts on piston 22 via a plunger portion 19 passing through an aperture 20 in a wall 16 of a casing 14. The hand lever 13 connects with the spool 40 of the spool valve 38 by a plunger 44 spigoted into a bore 43 in the spool 40 and a spring 45 serves as a feel device for operation of the hand lever 13.
