Abstract: 519,673. Shoe-burnishing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Aug. 30, 1938, No. 25339. [Class 17 (i)] In an oscillatory edge-setter, vibration transmitted from the oscillatory parts of the machine to the frame is lessened by mounting the former in a heavy casing maintained in spaced relation to the frame by resilient means. A rotating drive shaft has at each end a cylindrical crank, the two cranks being parallel to each other with their axes at an angle to the axis of the drive shaft, to lessen vibration due to unbalancing of the rotor under load. Improved means of little weight urge the tool toward the work. A driven shaft 24 has at its ends a pair of cranks 26, 28 parallel to each other and inclined at an angle to the axis of the shaft 24. On each of the cranks ball bearings 81 support a sleeve 82 with integral trunnions 86 having bearings in arms formed at the rear end of a tool shaft 34. The axis of the shaft 24 cuts the axes of the cranks 26, 28 at the axes of the trunnions so that the rotation of the shaft 24 produces oscillation of the shafts 34, movement about the trunnions being lost. Coaxial with the shaft 34 is a sleeve supporting a tool head 106 and a pin 96 abutting against a thrust bearing 120 and carrying a spring 122 urging the tool head 106 rearwardly. Bosses 153, 155 on the tool head carry the shanks of burnishing tools 150, each tool being urged outwardly of the shaft 34 by an adjustable spring wound on a pin 164 and having its end 162 engaging a ball seated in a cup in the shank. A leaf spring 154 centralizes the tool about its own axis. The tool head has lugs engaging grooves in the head 176, and is moved outwardly by a handle 182 when it is desired to rotate the tool head 180 degrees to enable the uppermost tool to be moved to the lowermost,. operative, position. All this mechanism is supported by a pair of massive casings, one for each crank 26, 28, each resiliently held in position by eleven springs. Springs 56, 58 engage the casing near its forward end, a single spring 44 supports the rearward end, and a pair of springs 42, 46 the intermediate part of each casing. Four converging springs 48, 52 engage the rear of each casing, and a pair of converging springs 66 the front. The machine is intended to allow static balance. The contions per minute. A weight 134 on each crank is intended to allow static balance. The construction of parallel cranks with inclined axes is intended to allow static balance. The congroove 100 in the head of the pin 96 and cooperating rib 102 are provided to facilitate assembly.

Abstract: 1414416 Amphoteric ion-exchange resins ICI AUSTRALIA Ltd and COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION 30 May 1973 [31 May 1972] 25752/73 Heading C3P Amphoteric ion-exchange resins are prepared by polymerizing, using free radical initiating means, a heterogeneous mixture comprising an aqueous solution of an allylamine salt of a mineral acid (e.g. hydrochloric, sulphuric, nitric or phosphoric acid) and an ethylenically unsaturated carboxylic acid or derivative thereof, at least a major proportion of which is present in the mixture in a separate phase finely disposed in the aqueous solution. The allylamine salt may be derived from an allylamino compound such as triallylamine, methyldiallylamine, ethyl diallylamine, 1,4 - bis - (diallylaminomethyl) - benzene, 1,6 - bis - (diallylamino) - hexane and mixtures thereof. The acid (or acid derivative) monomer is (or is derived from), for example, maleic, fumaric, itaconic, acrylic, methacrylic, crotonic, allylacetic, butene - di- or-tri - carboxylic, citraconic, mesaconic or aconitic acid; suitable derivatives include anhydrides, salts such as zinc, barium or calcium salts, alkyl esters, imides and amides and preferred derivatives are arylamides of maleic or acrylic acid (e.g. N-phenyl-maleamic acid). Polymerization can be initiated with a free radical catalyst, e.g. a redox system, or preferably with high energy radiation, e.g. #-rays, γ-rays, X-rays, electron beams or neutron beams. Ion-exchange resins of appropriate particle size may be obtained with or without the use of a secondary liquid phase, which acts as a dispersion medium for the heterogeneous monomer mixture; examples of such media are aromatic solvents and petroleum ethers. After polymerization, an after treatment, such as hydrolysis, may be necessary to free blocked acidic groups in the resin.

Vibration-dampers of the -friction type with multiple discs for vehicles are adapted to operate with greater resistance in one direction than in the other by means of screw mechanism and a spring. The lever 14 connected to the axle is secured to a sleeve 10 which is rotatable on the base plate 1 secured to the frame. A flange projecting inwardly from the hub of the arm 14 is channeled or slotted to provide jaws 32 which engage slots in alternate friction discs. The remaining discs are similarly engaged by jaws 55 on a member 51 connected to the pressure plate 47 which engages a screw on a sleeve 40 mounted on the fixed central spindle 6. The sleeve 40 is movable longitudinally on the spindle 6 but is prevented from rotating thereon by teeth 5. The movement of the plate 47 on the sleeve 40 is limited by a shoulder 60 and a washer 62. A helical spring is held between an end plate 71 on the spindle and a plate 77 which bears on a shoulder on the spindle except when it is engaged by the end of the sleeve 40. For small movement of the arm 14 there is no relative movement of the friction discs, the arm and the pressure plate 47 turning together. When the arm moves through greater angles, the plate 47 engages either the shoulder 60 or the washer 62 and relative movement of the discs takes place. When it engages the shoulder 60, the sleeve 40 is moved longitudinally to engage the plate 77 whereby spring pressure is applied to the discs and checks rebound of the vehicle springs. When the plate 47 engages the washer 62, the relative movement of the discs takes place without thrust between them.
