Title: Improvements in or relating to apparatus for grinding balls
Inventor: PACHMANN GERFRIED
IPC: B24B11/02
Filed: 1956-03-09
Abstract: 815,156. Grinding balls. VEB TRANSFORMATORENWERK K. LIEBKNECHT. March 9, 1956, No. 7484/56. Class 60. A ball 2, Fig. 1, of magnetizable material is ground by locating it in a holder 1 which is shaped to correspond with a valve seating for the ball or actually constitutes a valve seating for the ball, and moving it with the holder over a magnetic base 3 in such a manner that it rotates in all directions in the holder during this movement. The ball is moved in a circular path over the annular upper surface of the base 3 by its engagement with the lower end of the hollow cylindrical holder 1 which is itself driven in the desired circular path around the axis of the base 3; abrasive 6 is provided between the lower end of the holder and the upper surface of the ball. In one arrangement, the holder 1 is driven by means disposed outside its circular path and does not rotate about its own axis. In the arrangement shown in Fig. 3, four holders 11 ... 15 arranged above the magnetic base are each fitted with a pinion 17 meshing with inner and outer gears 18, 19 either of which may be driven so as to move the balls in a circular path while at the same time rotating the holders about their own axes. This arrangement may be modified by substituting a friction drive for the gear drive. If desired, several holders 1 may be arranged at different distances from the axis of the base so that they move in concentric circles, the drive being effected outwardly from the innermost gear.

Title: Improvements in or relating to methods of, and apparatus for, cleaning metal articles
Inventor: ENGLAND EDWIN DENNIS
IPC: C23G3/00
Filed: 1955-03-15
Abstract: A method of cleaning or degreasing metal objects comprises totally immersing the objects in a bath of a suitable liquid in spaced relation to the bottom and sides of the bath, and then submitting the objects to horizontal rectilinear reciprocal motion at a speed such that the surface of the liquid, or of a non-volatile layer of liquid covering the treating liquid, if such a layer is used to prevent loss of volatile treating <PICT:0790640/III/1> <PICT:0790640/III/2> liquid, is unbroken.  The reciprocal motion is preferably harmonic or approximately harmonic.  Figs. 1 and 2 show a suitable apparatus in front and side elevation respectively.  Tank 10, which contains treating liquid to depth 37, has a basket-like perforated container 11 suspended in it supported by wheels 15 which run along two pairs of horizontal rails 13, 14.  The objects to be treated are placed in container 11, and horizontal rectilinear reciprocal motion is then imparted to the objects by means of motor 40 and connecting rod 43, which is coupled by a pivotal connection 45 to the container 11.  The speed of reciprocation is selected so that the surface of the liquid is unbroken, though it may be rippled.  The treating liquid is heated by means of electric elements 22 controlled by thermostats 46, and the tank is provided with an exhaust duct for fumes 35.  The lid 24 of the tank is provided with rollers 25 at each corner and may be raised by the operation of motor 32, which winds up the supporting chain 30 and causes rollers 25 to run up along rails 26, the weight of the lid being counterbalanced by weights 31. The perforated container 11 may be replaced by a platform corresponding to the bottom of the container.  The apparatus is preferably used in a group of three, the first tank containing a pretreating, partly spent, liquid mixed with water, the second containing the full strength treating liquid which is thereafter transferred to the first tank, and the third tank containing a water rinse.

Patent GB-1025935-A (GB)
Title: Expandable and cellular polymers and articles comprised thereof
Inventor: CROFT PETER WILLIAM
IPC: C08J9/18
Filed: 1963-02-28
Abstract: Expandable polymers may be manufactured by steeping in a liquid consisting of or comprising a vaporizable expanding agent, a particulate thermoplastic polymer consisting of or comprising a rubber/vinyl-aromatic compound graft interpolymer, the gel content of which is wholly or substantially wholly stable gel, and separating the resultant steeped polymer from the excess liquid after an expandable polymerforming amount of expanding agent has been absorbed.  The term "stable gel" means the kind of gel which is little affected when the polymer in which it is dispersed is mechanically worked in a heat plastified condition.  Mixtures of vinyl aromatic monomers may be used for forming the interpolymer as may mixtures of a vinyl aromatic monomer with e.g. acrylonitrile or the acrylate and methacrylate esters.  The preferred vinyl aromatic monomer is styrene. Examples of suitable rubbers are natural rubber, polybutadiene, polyisoprene, copolymers of butadiene with styrene or acrylonitrile, polyisobutylene rubbers and butyl rubber in amounts of from 4 to 10% of the monomeric material. Suitable vaporizable liquid expanding agents are aliphatic hydrocarbons boiling between 10 DEG and 80 DEG  C., e.g. pentane, hexane and petroleum ethers, if desired in a mixture with a liquid having a solvent or softening action or the polymer, e.g. toluene, chlorofluoromethane, or methylene chloride.  A solid auxiliary expanding agent may also be added to the polymer either before or after steeping.  Suitable solids are a mixture of an alkali or alkaline earth metal carbonate or bicarbonate with a powdered acid, e.g. citric acid or tartaric acid or an acid, e.g. stearic acid or benzoic acid may be dispersed in the liquid expanding agent.  Nitrogen containing compounds or hydrated salts may also be used.  The thermoplastic polymer may be formed by a stagewise polymerization process, the first stage of which is carried out under shearing conditions to a maximum of 30% conversion of the polymerizable monomer.  The particles may be steeped so that each one fully absorbs the expanding agent and after separation from excess liquid they may be devolatilized to reduce the total content of vaporizable expanding agent to between 6 and 8% by weight. Extrusion techniques may be used to form foamed products or the particles may be steam moulded.
