Title: Improvements in and relating to the manufacture of flexible tubes of polymerised aryl olefines and of insulated electrical conductors
IPC: B29C48/15
Filed: 1933-10-16
Abstract: Flexible tubes or hoses of polymerization products of aryl olefines such as polystyrol are produced by pressing the material through an annular nozzle at high temperature and drawing the tube at a speed which is greater than the outlet speed of the said nozzle.  Electric insulated conductors are made by passing a metallic conductor through a hole provided in the central part of the nozzle during the <PICT:0423314/IV/1> formation of the tube.  Using the apparatus described, a copper wire b passes through the central opening in a nozzle h through which is pressed the polystyrol g.  The tube containing the wire is drawn off by means of a wheel e and wound on a bobbin f.  A cooling device n is provided.  In a modification, thin layers of fat are introduced between the metallic conductor and the first insulating covering and between individual insulating coverings. In another modification, the conductor is surrounded with a winding of insulating material, e.g. a cord or thread of polystyrol, before drawing the flexible tube thereon.  The insulated conductors may be stranded into groups after heating to about 50--70 DEG  C., and the groups may be covered with a tubular covering of polystyrol, preferably without using the intermediate layer of fat or the like.  Specification 419,900 is referred to.

Title: Process and Apparatus for Controlling the Furrow-Depth of a Plough drawn by a Traction-Engine
IPC: A01B67/00
Filed: 1967-06-21
Abstract: 1,183,865. Regulating I.C. engines. ALEX. FRIEDMANN K.G. June 21, 1967 [June 24, 1966], No. 28647/67. Heading F1B. [Also in Division A1] The furrow-depth of a hydraulicallycontrolled plough drawn by a traction engine having a fuel injection I. C. engine is varied by hydraulic control means controlling the lifting and lowering of the plough in dependence upon the amount of fuel fed per unit time by a fuel pump supplying fuel to the fuel injection pump in dependence on the number of revolutions of the fuel supply pump. Fuel is supplied from a fuel supply pump 2, having a speed-dependent pressure characteristic, to a fuel injection pump 3 which supplies injection nozzles 4. An auxiliary pump may be arranged upstream of pump 2. An overflow valve 6 loaded by a progressive rate spring 7 controls the pressure in space 5 which is transmitted to act on diaphragm 9 in a hydraulic control 8. Diaphragm 9 acts on a valve plate 11, subjected to an adjustable spring load, which controls the fluid-flow through conduits 14, 15 to a control piston which in turn controls a lifting piston for the plough. Operation: With increasing plough load the engine speed and thereby the pressure in space 5 and acting on diaphragm 9 is reduced. Valve plate 11 tends to close the fluid supply through conduit 15 to the control piston and thereby the furrow-depth is reduced. The pressure in space 5 is also reduced because the fuel injection pump is controlled to increase fuel delivery to injectors 4 which results in less fuel being fed back through overflow control 18. When the plough load decreases the system operates in a similar manner to increase the furrow depth. In another embodiment a fixed throttle (20, Fig. 2 not shown) is arranged downstream of the overflow valve 6. A further adjustable throttle (30), arranged downstream of the overflow valve 6 by-passes the fixed throttle (20) back to the inlet side of the fuel supply pump 2 and the pressure in this branch acts on the control diaphragm (24) operatively controlling the furrow depth. The fuel injection pump 3 is connected to the pressure space 5 upstream of the overflow valve 6. The fixed throttle (20) may be replaced by an adjustable throttle. In a modification of Fig. 2 the excess fuel-flow from the fuel injection pump (3 Fig.3 not shown) passes via a separate collection chamber (31) to the downstream side of the overflow valve (6).
