Title: Improvements in and relating to plasticising, reclaiming or re-working vulcanised rubber
IPC: C08J11/18
Filed: 1944-10-09
Abstract: Vulcanized rubber is reclaimed by heating it in a finely divided condition in the presence of a small proportion of polycarbocyclic phenolic or amine bodies to 140-170 DEG C. in an autoclave in the presence of a restricted amount of oxygen, and thereafter treating the rubber mechanically to obtain a coherent mess.  The quantity of oxygen must vary between the equivalent of 0 and 20 c.c. of air per gram of rubber hydrocarbon, the proportion approaching the lower limit in the case of rubber substantially free from filling material, rising to the maximum when the filler constitutes approximately 50 per cent. of the rubber.  About 2-5 per cent. of the polycyclic body which may be a - or b -naphthol; a - or b -naphthylamine; or condensation products of such amines with aldols or aldehydes is incorporated in the rubber and the mix heated for 1-3 hours.  It may be worked as a Banbury type mixed before treatment on a rubber mill. Specification 571,603 is referred to in the first and second Provisional Specifications.

Filed: 1921-07-19
Abstract: 166,560. Ges. f³r Drahtlose Telegraphie. July 21, 1920, [Convention date]. Frequency, changing.-In an arrangement for producing electric oscillations by the aid of choking-coils or transformers with auxiliary directcurrent magnetization, doubled frequencies are removed by a winding which is short-circuited by a large condenser, and a frequency which may be any odd multiple of the fundamental frequency is obtained in a directly-coupled tuned output circuit. In the arrangement shown in Fig. 1, a high-frequency generator 1 is connected to coils 2 wound on separate iron cores 3, the middle points of the coils being connected to a condenser 6 of so large a capacity that its resistance to any of the harmonic currents is negligible. Directcurrent magnetization of the cores is obtained by connecting the condenser to a source 7 through an adjustable resistance 8. The aerial or other output circuit 4 is tuned to the desired odd harmonic of the frequency of the generator 1. In a modification, a single core with three limbs is used instead of the separate cores 3, the coils 2 being wound on the outer limbs of the core. In another arrangement, Fig. 3, the coils 2 are replaced by a pair of transformers 5, the secondary windings of which are connected to the condenser 6 and direct-current source 7. The Specification as open to inspection under Sect. 91 (3) (a) includes also arrangements in which the coils 2 or the secondary windings of the transfcrmers 5 are short-circuited on themselves or through a resistance. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,042,493. Electrophotographic processer. RANK XEROX Ltd. May 17, 1963 [June 7,1962], No. 19692/63. Heading G2H. An image is formed by deformation on a liquid or thermo plastic layer separable from a xerographic plate, so that the layer may be removed from the plate displayed, erased, and then returned for re-use. The layer is deformed by induction effects of electrostatic latent image on the xerographic plate. In one embodiment, a xerographic plate 10, Fig. 1, carries a latent electrostatic charge 13 formed in known manner. The plate has a photoconductive postively charged insulating layer 12 on a conductive backing 11. The plate 10 is maintained in the dark and positioned on supports 14 closely adjacent an image plate 15 having a conductive layer 16, e.g., of paper or metal and a conductive liquid layer 17 e.g. of water, alcohol, mercury, Aquadag or a liquified resin material. A space 19 of between 1 and 5 units is maintained between the layers 12 and 17, while the layers backing 11 and layer 16 are connected to earth. Lines of force from the electrostatic image exert physical forces of attraction on the layer 17 which forms a relief image 18. In another embodiment, a deformable layer 21, Fig. 2 (not shown) solid at normal room temperatures is used in place of layer 17, Fig. 1. The layer 21, Fig. 2, (not shown) which may be "Staybelite" is supported by a conductive layer 22 on a heating element 23. In another embodiment a xerographic plate Fig. 3 (not shown) is positioned above a deformable insulating layer 25 and conductive liquid layer 26. A voltage is applied between layers 11 and 27 and the layer heated by heater 23, so as to liquify the deformable layer 2 5. The photoconductive layer 12 is exposed imagewise by a projector 31. The layer 25 is deformed by forces induced in the layer 26. In another embodiment a liquid layer 35, Fig. 4 (not shown) is positioned between layer 12 and a conductive deformable layer 36. Two non miscible liquid layers 38 and 39, Fig. 5, are positioned between layers 12 and 27. The layer 38 is insulating, e.g. oil and layer 39 conductive e.g. water. In another embodiment layers 36, 65, Fig. 6, (not shown) are liquifiable materials solid at normal room temperatures.

Filed: 1972-04-28
Abstract: 1383586 Limiting moment arm load of crane booms HIAB-FOCO AB 28 April 1972 19767/72 Heading B8B A crane comprises a post 1 on which is pivotally mounted a loading boom 3 comprising inner and outer arm parts 4, 5, the arm part 4 being movable about pivot 2 by means of a ram 9. The arm part 5 is movable about pivot A by means of arm 12. The boom also includes an arm 6 in which a load hook 7 is mounted, this arm being movable by means of a ram 14, into and out of the arm 5. The rams 9,12, and 14, are connected respectively to operating valves 19- 21, each comprising an operating piston 28 movable in a valve housing 27 (Fig. 3) and having points of connection 31, 34, to the respective rams, and being in connection with an oil reservoir 17. In operation of the crane, if the liquid pressure in the line 22 to the ram 9 exceeds a predetermined, value, the pressure in the line 22 will rise, and the pressure in the line 23 willalso rise, and will propagate through a channel 51 in the piston 50 of a two way valve 24 causing the piston 50 to be displaced upwardly against the action of a biasing spring 60 allowing pressurized liquid to pass through line 25 to a cylinder 26 at the bottom of each valve 19-21. This results in the moving of a piston 45 upwardly to abut against and displace the oper ating piston 28 of the valves 19-21 from the position of Fig. 3 to that of Fig. 4 in which the valves are closed thus stopping the supply of oil to the cylinders 9, 12, and 14, thus stopping further increase in the value of the moment of loading. By the use of central levers (not shown), the pistons 28 may be moved to a position (Fig. 5) opposite to that shown in Fig. 3, in which supply of pressurized oil to the cylinders 9, 12, and 14, is in the opposite direction, thus retracting the loading beam 3 to decrease the moment of loading.

Abstract: 1,260,655. Feeding sheets. DE LA RUE INSTRUMENTS Ltd. 22 April, 1969 [26 April, 1968], No. 19862/68. Heading B8R. Bundles 1a of banknotes in a pile 1 on a table 2 are separated in turn from the top of the stack by suction cups 5 carried on arms 8, 9 pivoted at 13 to allow vertical movement and on rods 10 and 11 to allow horizontal movement. A start signal from a note-handling apparatus drives a vacuum pump to create vacuum at 23 and drive a motor 3 to raise the table 2 through chains 4, provided the top of the pile is not in contact with the cups 5. When the pile contacts the cups, suction in the system opens a switch Sl in the circuit of the motor 3. A further signal energizes a motor 18 and a crank disc 15 rotates to move the cups from over the pile to over a shoot 19 and back. As the cups move away from the pile, they are raised by a stationary cam 14 and allow a switch S2 in the circuit of the motor 3 to open. When the cups are over the shoot, a projection 28 on the disc 15 opens a valve 26 to release the suction and drop the bundle into the shoot. Thus the table 2 is raised only when the cups are over and out of contact with the pile.
