Title: Apparatus for distributing liquid under pressure in machines and apparatuses with hydraulic movements
IPC: F15B11/20
Filed: 1945-07-31
Abstract: 614,469. Liquid-pressure engines and hydraulic machines. DETREZ, R. July 31, 1945, No. 19570. Convention date, April 21, 1944. [Class 69 (ii)] In an apparatus for actuating a plurality of driving pistons through a distribution of liquid under pressure to distributers controlling them, the latter control one another, their piston-rods or other part associated therewith including one or more passages adapted, at the opportune moment through the displacement of the piston-rods or other part in their cylinders to be brought into communication with passages provided in the cylinders, these latter passages being adapted to receive the liquid under pressure and to transmit it to the distributer or distributers controlling one or more of the driving pistons to be actuated thereby during the above-mentioned communication. Driving pistons a<1>, b<1>, c<1> have distributers a', b<4>, c<4> respectively, and each piston and cylinder is provided with passages such as a<10>, all, a<12>, a<13>. Liquid is supplied from a pump p to the chain lines, being returned along the dot-dash lines to a tank R. The thick full lines show the feed to the cylinders, and the thin full lines the feed to the distributers. Piston c<1> is at the top of its stroke, liquid flows from line P into passages c<11>, c<14>, c<15> to distributer a<4> raising valve a<3> so that liquid flows from line P through passages a<5> and a<6>, and is exhausted through passages a', a<8>, a<9> to the tank R, thereby raising piston a<1>. In its top position piston a<1> allows liquid to flow from line P and passages all, a<13>, a<15> to lower the distributer valve b<3> so that there is flow through the line b<7> and exhaust through line b<6> causing the piston b<1> to travel to its bottom position. Liquid from line P then flows through passages b<11>, b<10> into line b<15> to lower distributer valve a<3>, putting line a<6> to exhaust and line a' to pressure so that piston a<1> is lowered. Liquid then flows from line P through passages a<11>, a<10>, a<12> to raise distributer valve b<3> and lower distributer valve c<3>. Liquid flowing through distributer b<4> then raises piston b<1>, while that flowing through distributer c<4> lowers piston c<1>. Liquid from line P then enters passages c<11>, c<10>, c<12> to raise the valve c<3>, thereby reversing the flow to raise the piston c<1> to its top position, and the whole cycle is then repeated. The speed of operation may be controlled by a throttle valve 17. Specification 581,404, [Group XXX], is referred to.

Patent GB-1127912-A (GB)
Title: Improvements in or relating to the winding of synthetic textile yarns or filaments
Inventor: GREENWOOD DAVID
IPC: D01H1/02
Filed: 1965-05-10
Abstract: 1,127,912. Ripg-spinning apparatus. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 April, 1966 [10 May, 1965]. No. 19629/65. Headings D1D and D1F. A method of winding yarn on to a bobbin by a ring and traveller, comprises rotating the bobbin at a speed lower than that of normal winding while the yarn is wound on to a wastereceiving end portion of the bobbin, applying a tension to the yarn during the low speed rotation of the bobbin by means of increased drag between the traveller and the ring brought about by magnetisation of the ring or the traveller or both, and thereafter increasing the speed of rotation of the bobbin to normal winding speed and winding the yarn on to the body portion of the bobbin. Either the ring or the traveller may be magnetised or an attractive force between the ring and the traveller may be obtained by the use of a permanent magnet, e.g. an annular magnet disposed near or in the ring. The process is useful in the winding of synthetic filaments or yarns which are heated during stretching, e.g. by a heated snubbing pin disposed between a pair of feed rolls on the one hand and draw and separator rolls on the other, the peripheral speed of the draw roll being higher than that of the feed rolls. For convenience, threading-up takes place before the pin is heated; if on the one hand the yarn is allowed to remain in contact with the pin, breaks occur as the pin is heated up; on the other hand, if the yarn is .taken up at normal speed, undue waste of yarn results. Consequently the wastage is minimized by rotating the take-up at low speed, by an auxiliary motor through an over-running clutch which permits the motor to free-wheel during highspeed winding. At low take-up speeds, however, the yarn between the draw rolls and the traveller is normally virtually without tension, and by imposing a magnetic drag on the traveller .the regularity of the take-up of the yarn is improved.
