Title: Production of expanded plastics materials from high molecular weight olefin polymers
IPC: C08J9/00
Filed: 1972-05-26
Abstract: 1382070 Expanded crystalline olefin polymers BADISCHE ANILIN- & SODA-FABRIK AG 26 May 1972 [29 May 1971] 24886/72 Heading C2C Expanded plastics material are made from a high molecular weight olefin polymer whose X- ray crystallinity at 25 C. is more than 50% by weight by mixing polymer at a temperature which is from 50 to 100 C. above the crystallite melting point of the olefin polymer and at a shear rate of from 20 to 200 seconds<SP>-1</SP> at superatmospheric pressure with an unsubstituted or halosubstituted aromatic hydrocarbon, the mixture is introduced into a zone in which it is homogenized at a temperature of from the crystallite melting point of the polymer to a maximum of 50 C. above the same and at a shear rate of from 500 to 1500 seconds<SP>-1</SP> with, as expanding agents from 5 to 40% by weight based on the olefin polymer of an aliphatic hydrocarbon and/or a halo-substituted aliphatic hydrocarbon whose boiling point at a pressure of 760 torr. is from 30 to 200 C. below the crystallite melting point of the olefin polymer, at a pressure which prevents expansion of the mixture, to form a gel, the gel is then cooled under superatmospheric pressure to a temperature which is from 10 to 60 C. below the crystallite melting point of the olefin polymer and it is then forced into a zone in which a pressure prevails which is lower than the vapour pressure of the expanding agent in the gel. In the examples, crystalline polyethylene or polypropylene was mixed with tale or barium stearate and then with (i) xylene, toluene or benzene, and optionally polyisobutylene and (ii) n-heptane, n-pentane, n-butane, iso-butane- and/or isopentane and optionally polyisobutylene or a copolymer of isobutylene and vinyl ether, under the above conditions and the mixture was extruded to form expanded strands which were cut into particles. The particles may be kept under heat and pressure to completely expand them and then heated in a mould and sintered together by compression.

Patent GB-817654-A (GB)
Title: Improvements in or related to variable-speed hydraulic transmissions
IPC: F16H47/04
Filed: 1957-08-09
Abstract: 817,654. Variable-speed gear. REICHENBACHER. H. Aug. 9, 1957, No. 25131/57. Class 80 (2). Variable-speed planetary gearing comprises a driving-shaft A carrying stepped planet pinions 11, 12, the planet pinions 12 meshing a gear fast on a driven shaft B and the planet pinions 11 meshing two reaction elements, the first reaction element consisting of an internally-toothed ring 21 driving through a gear C to a gear C<SP>1</SP> on the shaft of a variable capacity swash-plate oil pump C<SP>11</SP> and the second reaction element being a sun gear 1 driving through a gear D to a gear D<SP>1</SP> on the shaft of a variable capacity swashplate oil motor D<SP>11</SP>, a common housing containing the pump and motor C<SP>11</SP>, D<SP>11</SP> and being turned about an axis E-E to vary the pump and motor capacities and thereby adjust the gear ratio. In the form shown, the axis of the pump C<SP>11</SP> is offset in the plane of Fig. 1 by an angle y from the axis of the motor D<SP>11</SP>. In the position of Fig. 1, the axis of the motor C" is parallel to the axis of the gear, so that the pump cannot work and no oil is passed. Accordingly, the gear C<SP>1</SP> and the associated reaction ring 21 are free, so that the pump D<SP>11</SP> is stationary and the planetary gear transmits drive at a first fixed ratio between the shafts A, B. By turning the casing of the pump and motor about the axis E-E until the axis of the motor D<SP>11</SP> is parallel to the main axis of the gear, the motor is similarly prevented from receiving oil from the pump, while its output shaft, the gears D<SP>1</SP>, D and the reaction sun gear 1 can turn freely. The planetary gear therefore again transmits drive at a second fixed ratio between the shafts A, B. With the pump and motor casing turned at an angle about the axis E-E in between these two positions, drive is transmitted between the shafts A, B with a ratio depending on the angular setting of the casing. If the casing of the pump and motor is turned about the axis E-E beyond either of the two neutral positions, the functions of the pump and motor C<SP>11</SP>, D<SP>11</SP> are interchanged.
