Title: Electrodes for electrochemical cells
IPC: H01M4/80
Filed: 1972-12-22
Abstract: 1411100 Electrochemical cell electrodes SIEMENS AG 22 Dec 1972 [23 Dec 1971] 59536/72 Heading H1B An electrode for use in rechargeable or metalair cells comprises a body formed of parallel fibres of electrically conductive material which carries active electrode material and which is supported on a layer, with a liquid permeable reinforcing layer disposed about the body, wherein the fibres are perpendicular to the supporting layer, the active electrode material comprises a metal powder with carbon and a binder, and the active electrode material is distributed within the body to provide alternate coarsely porous and finely porous zones extending perpendicular to the supporting layer. The coarsely porous zones consist substantially of fibres and the finely porous zones consist of fibres with active electrode material and may include some regions consisting solely of active material. As shown in Fig. 1, active electrode material layer 13 is provided on one or both sides with a fibre layer 11, 12 of steel wool or Ni, Ag or graphite fibres, the layers being compressed so that the active material partially penetrates into the adjacent steel wool skeleton structures. All the fibres in layers 11, 12 are parallel and extend longitudinally of the plate, and, as shown in Fig. 2b, the plate thus manufactured is cut transversely of the longitudinal fibre direction into strips 22. The strips 22 are then arranged parallel on their narrow sides on a supporting layer 23, Fig. 2c, comprising a plate, lattice or gauze of Ag, Ni or Fe, with the fibres 24 aligned perpendicular to the supporting layer 23. Alternatively, the compressed plate may have a series of notches formed alternately on opposite sides thereof, Fig. 3 (not shown), and then folded along the notches to give a similar structure to that shown in Fig. 2c. The fluid permeable reinforcing layer comprises expanded or fabric metal, e.g. Fe or Ni, which may be spot-welded to the supporting layer. The active electrode material may include Fe, Co or Cd powder, to a suspension of which in water is added a bonding agent such as a latex emulsion containing acrylonitrile-butadiene-styrene copolymer which is precipitated on to the powder by adding dilute acetic acid whilst stirring vigorously. The carbon, e.g. an acetylene black, is subsequently added followed by an activator such as sulphur or a sulphur-containing substance, e.g. a sulphide of hydrogen, iron, tin, potassium or sodium. The prepared mixture is filtered off on to a surface to form the plate 13. A specific example is given with dimensions and proportions of materials. The activator may alternatively be added to the electrolyte of the cell, which may comprise KOH or NaOH to which may be added LiOH.

Patent GB-756620-A (GB)
Abstract: 756,620. Turning-gear. UHER, E. June 23, 1954 [June 26, 1953]. No. 18437/54. Class 7(5) [Also in Groups XXXV and XXXVII] The invention relates to a method of and apparatus for starting an engine by a flywheel 3 wherein a dynamotor armature 2a is rotatable upon the engine crankshaft 4c and the starter housing carries poles 2b and 2c for the series and shunt windings, respectively; the flywheel 3, which has a clutch lining, is secured to the armature 2a and co-operates with a clutch plate 4 that is connected to the crankshaft 4c by a diaphragm 4a. A pedal lever 6b and linkage 6, 6a is used to disconnect the clutch members and the dynamotor shuntwinding so that the starter operates as a series motor when supplying energy to the flywheel 3; when the lever 6b is released, the clutch becomes operated and enables the engine to be cranked by the joint effort of the flywheel and the starter motor, which latter now operates 'as a compound machine, (see also Group XXXV). The starter switch may be operated conjointly with the pedal lever and a switch open-circuiting the shunt field during the time the flywheel is being accelerated (see also Group XXXVII]. The engine cranking period may be fixed by a thermally responsive element in the starter switch or the period may be dependent upon the ambient temperature; the cranking period may be determined by a mechanical time-delay mechanism in the starter switch. The coupling of the flywheel and dynamotor may be effected in response to a centrifugal switch or a timedelay apparatus not shown. After starting the dynamotor is driven by the engine to function as a shunt dynamo.

Title: Rodenticidal dusts
IPC: A01N61/00
Filed: 1978-07-11
Abstract: A rodenticidal composition comprises a carrier dust, a toxicant and a UV-fluorescent pigment. The composition, when placed in patches on a surface is picked up by the animal on its feet, tail and fur, from where the toxicant is ingested into the body when the animal grooms itself. In addition, the composition is spread around the surface by the rodents and the tracks can be detected by illuminating the area with a UV lamp. On close examination even single tracks can be followed, which represents a significant improvement over visibly dyed rodenticidal dusts. The preferred dye is a red-fluorescing melamine formaldehyde sulphonamide pigment. Since few other materials fluoresce in the colour range, trace amounts of dust containing this dye stand out from the background. The preferred carrier dust is a basic slag or a mixture of basic slag with ground phosphate rock, whilst the preferred toxicant is  gamma -hexachlorocyclohexane.
