Title: Improvements in accumulator plates
IPC: H01M4/56
Filed: 1921-01-10
Abstract: 171,921. Cattley, L. de M. Jan. 10, 1921. Electrodes.-An accumulator electrode consists of equal parts of lead oxide and lead sulphate mixed with cooked potato and made into a paste with sulphuric acid. 20 per cent of potato may be used. The paste is moulded into plates, pressed and dried and then wrapped in paper and heated in a crucible packed with soot to exclude air. The temperature is raised, gradually to 100‹ C. and then more rapidly to 535-550‹ C. and finally lowered gradually to 50‹ C. The electrode is then removed and purified by connecting it to a zinc plate in a bath of sulphuric acid or by placing it in a bath in conjunction with a positive electrode and charging until the evolution of sulphuretted hydrogen ceases. The electrodes. may be cylindrical or flat and solid or hollow. Specification 19109/13 is referred to.

Abstract: 1499541 Spreading implements C VAN DER LELY NV 14 Jan 1975 [18 Jan 1974] 1605/75 Heading AID Material is fed under gravity from a hopper 2 (Figs. 1-16) through an outlet slot 37 (Fig 4) in at least one of hopper spouts 31 and 32 through holes 43-46 in a flow control slide 42 and through co-operating inlet apertures 80-83 into constant-section channels 62- 65 of four distribution pipes 70-73 through which air is passing from an air chamber 91 supplied by blower 153, the hopper 2 being closed by lids 221, 222 and sealed at 41 to the distribution channels 62-65 to prevent air from escaping. A pipe 166 connects the air chamber 91 and the interior of the hopper 2. The distribution pipes 70-73 deliver the material directly and via pipes 108-110, respectively to outlets 111-114 provided with spreading plates, e.g. 117 (Figs. 1 and 2). The flow control slide 42 is movable across the outlet slot 37 in each spout 31 and 32 by means of a handle 214 operating linkage 201-215 (also in Fig. 14 not shown) in which some links are disengageable so that material can be made to flow from one or other of the outlet slots 37. The flow control slide 42 is urged upwards against the edges 37, 39 of the slot 37 by means of a leaf spring 96. Inclined baffles 86, 87 (Fig. 4) direct the material through the inlet apertures 80-83 somewhat along the channels 62-65 of the distribution pipes 70-73. The channels 62-65 are fixed together and pivoted at 95 for downward swinging together with the distribution pipes 70-73, but in use the outer ends of the pipes 71-73 seal at 105 (Fig. 12) to the pipes 108- 110. The pipes 108-110 are of plastics, and the longest pipe 108 also has an outer metal tube 123. The pipes 108-110 are connected together by a bracket 125 pivoted about longitudinal pins 126 to a frame 127-129 fastened to a slightly inclined shaft 130 rotatable on the beam 26 of the implement frame, so that the boom comprising the pipes 108-110 is deflectable upwardly and/or rearwardly against gravity. Ground engaging shoes 257 and 258 are provided on the longest pipe 108 of end group 3 and 4 but wheels may be provided. An adjustable spring- loaded catch 137-146 prevents undue rearward deflection. Agitators 179, 181 are oscillated by links 176, 177 from a common shaft 173 which is driven, together with the blower 153, from the tractor power-take-off. A vane in the blower outlet may be adjusted manually or interconnected with the handle 14 for setting the flow rate of the material. In Fig. 17 a wheeled frame 274 supports a large hopper 275 whence material is supplied by an auger 279 to a hopper 271 corresponding to the hopper 2 but smaller, the auger 279 fitting closely within a cylinder 292 to prevent air from escaping from the hopper 271.

Title: Improvements in the treatment of textile materials
IPC: D06M15/263
Filed: 1933-01-18
Abstract: Woven or other fabrics are impregnated or coated with polymerization products of esters of unsaturated aliphatic acids or unsaturated aliphatic aldehydes, said products being substantially insoluble in water or dilute aqueous media and applied in amounts of 1 ounce or less per square yard.  Suitable polymerization products are those of crotonaldehyde and acrolein, crotonic acid esters, acrylic acid methyl or ethyl alcohol esters and the substance sold under the trade name of "Plextol A." Polymerization may be effected after application of the unsaturated compound to the material but is preferably effected at least in part before application, further polymerization being effected if required by heat or ultra-violet light.  Additions to the coating &c. materials may include plasticizers, natural resins, synthetic or semi-synthetic resins, and cellulose derivatives.  Solvents for the application of the materials are volatile or relatively volatile organic substances, e.g. acetone, dioxane, ethylene methylene ether, diacetone alcohol, ethyl lactate, esters of glycol, oxanones, chlorinated compounds and hydrocarbons. The medium should not have a pronounced solvent action on the textile but a medium having a latent solvent or swelling action may be advantageous, e.g. in the treatment of materials containing cellulose acetate, acetone or methylene chloride.  The textile materials treated may include mixed materials of natural or artificial silk and cotton and the solution may be applied to one or both surfaces or by immersion. The materials may be applied locally by printing or stencilling. Finely divided metal may be applied to the coating before hardening.  Pigments, dyestuffs &c. may also be added. Examples describe the treatment of a fabric having a cotton back and cellulose acetate face with a solution in a mixture of benzene, toluene and acetone or of trichlorethylene of the polymerization product of the methyl ester of acrylic acid or "Plextol A."

Abstract: 122,057. Kuyser, J. A. Jan. 31, 1918. Protective arrangements.-For the protection of alternating-current apparatus against internal insulation faults between turns of the same winding the resulting unbalancing of the voltages in two series-connected parts of the winding is used to operate automatic cut-out devices. In one form, two potential transformers are connected across the two parts of each phase winding, the transformer secondaries being connected in opposition and the relays for the cut-outs inserted in the connexions. In another arrangement, shown in Fig. 1 applied to a star-connected generator. each phase is connected to a reactance or to a potential transformer, and equipotential points A<1>, B<1> for example, on the phase winding and on the reactance are interconnected either directly through a relay or through the primary of a transformer C', the secondary of which is connected to the relay D<1>. Where two similar machines are available, equipotential points on corresponding phase windings are interconnected through relays. In the arrangement shown in Fig. 4, in which each phase consists of two parallel circuits, equipotential points such as A, A' are interconnected through a transformer, the secondary of which operates the relay.

Filed: 1927-01-24
Abstract: 294,494. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 24, 19'27. Gases, treating with electric discharge.-In the treatment of gases containing hydrocarbons in a furnace having a central electrode E and an annular or tubular electrode through which the gases pass, an insulating mantle H is arranged between the electrodes to prevent the arc taking the shortest path and to bring it to the length most favourable for the reaction. The annular electrode may be, constituted by the furnace mantle. A which is connected to earth, or by an electrode G separate from the furnace, Fig. 1. The insulating mantle may be adjusted by a lever J. The central electrode is covered with insulation F, but the length of the insulation mav be shortened if the diameter of this part of the furnace is increased. Inert gases may be introduced around the central electrode. In Fig. 3 the upper part G of the furnace mantle forms one electrode and is adapted to be cooled. The insulating mantle is formed by a tube H. The gases pass over the hot exterior of the tube before, passing into the arc. Examples are described of the production of acetylene from hydrogen and methane. Hydrogen is separated from the gases leaving the reaction zone and after mixing with the necessary quantity of methane is again passed through the furnace. Alternatively the hydrogen may be caused to act on carbon monoxide to produce methane which is then treated in the furnace. The yield of acetylene is increased by the addition of ethylene, ethane or oil gas. Acetylene and hydrocyanic acid may be obtained from the residual gases obtained in the synthesis of ammonia, the gases obtained in the destructive hydrogenation of coal, tar or mineral oils, or coke oven gas. In the latter case the carbon monoxide in the gas is first converted to methane or carbon dioxide.

Title: Improvements in or relating to conveyors
IPC: B65G47/48
Filed: 1958-01-22
Abstract: 841,400. Endless-chain conveyers. PFAFF A.G., G. M. Jan. 22, 1958 [Jan. 22, 1957], No. 2110/58. Class 78 (1). In a conveyer 5 for use as an assembly line of the kind which travels in a horizontal plane past stations A1 to D8 and is provided with a series of attachments 8 to each of which a load container 3 may be detachably connected, the containers move over a track 1 which is inclined downwardly with respect to the plane in which the chain travels and which is more than twice as wide as the containers so that the latter, when released from the attachment, slide by gravity to a position out of the path of the containers still attached to the chain. Each attachment 8, Figs. 3 and 4, consists of a frame 9 which is secured to the chain 5 and has a pivoted cover 11. Flanged rollers 12 on each frame run between guide rails 14, 15. The lower edge of the frame is extended to form a lip, which with the depending edge 16 of the cover, forms an aperture 18. This aperture receives a rod-shaped hook 29 mounted on each container and retains it until the cover is raised by the engagement of its depending portion 19 with one of a series of plungers 26 which is in the raised position. Each plunger is actuated by a solenoid 27 which is energized only when switches 36, 37, Fig. 2, provided at each station are actuated simultaneously by keys, e.g. 33, 34, Fig. 5, on a container. The distances of the switches 36 from the conveyer vary with the stations in which they are mounted, e.g. in the series of stations D they are all at a distance which ensures actuation by the projected key 33, Fig. 5, which is the key allotted to the stations D. The switches 37 in the series of stations D1 ... D8 are at different distances from the conveyer corresponding to the distances of the eight keys 34. In Fig. 5, the fifth key is shown projected and the container will be detached at station D5. The switches 36, 37 of each station are connected electrically to each other and to the corresponding solenoid 27. A safety switch 40 at each station is actuated by the weight of a container and since it is connected electrically to the corresponding switches 36, 37, a container cannot be released from the attachment 8 if the station is occupied. The re-engagement of a container with an attachment is facilitated by the provision of hinged flaps 53 which are spring-urged to inclined position. Each flap holds a container in position for the engagement of the hook 29 with the aperture 18. Since the hook is not parallel to the container, as it enters the aperture, the container will be drawn towards the conveyer to clear the following flaps and to be aligned with the other containers by contacting the ledge 56. A panel (not shown) is provided with signals to indicate which stations are free and which are occupied. This panel also contains holding keys which when actuated put the switches 36, 37 out of action.
