Title: A press for hydrostatic extrusion
Inventor: NILSSON JAN
IPC: B21C23/00
Filed: 1968-10-31
Abstract: 1,235,539. Extruding. ALLMANNA SVENSKA ELEKTRISKA A.B. 31 Oct., 1968 [1 Nov., 1967], No. 51682/68. Heading B3P. An hydrostatic extrusion press comprises a main operating cylinder 2 with a pressuregenerating piston 3 whose rod 5 extends into a high-pressure chamber 25 and a sealing pressure ring 16 which is urged against the end of the high-pressure chamber with a force dependent on the pressure in the chamber. The ring is mounted on a set of piston-rods 15 of either a set of separate pistons 14 in cylinders 13 in the piston 3 of the main cylinder 2 or of an annular piston in an annular cylinder in the piston 3. The individual cylinders 13 are interconnected by ducts 19, 21 and the upper spaces 18 of the cylinders 13 are connected to the upper space 6 of the main cylinder. The lower spacers 7, 20 are connected by a common line 9 to a pressure source or a reservoir. Initially a valve 10 directs fluid only to the upper spaces 18 of the cylinders 13 to lower the ring 16. After abutment the pressure rises in the spaces 18 and a pressure gauge 35 sends an impulse to the valve 10 to move it to a central position. The spaces 6, 18 are thus interconnected through an adjustable reduction valve 23. Thus the pressure in the space 18 which determines the pressure of the ring 16 against the chamber 25 is proportional to the pressure in the space 6 which is in turn related to the pressure in the high-pressure chamber.

Abstract: 1417158 Dual circuit brake systems; control valves AISIN SEIKI KK and TOYOTA JIDOSHA KOGYO KK 15 Nov 1972 [18 Nov 1971] 52809/72 Headings F2F and F2V A valve unit for a dual circuit brake system, respective pumps 84, 85, reservoirs 80, 81, accumulators 88, 89 and wheel cylinders 82, 83, comprises respective valve assemblies 50, 60 for each circuit, the first valve assembly 50 comprising a ball 58 and a valve spool 51 slidably received in a hollow seat piston 20 which itself is slidable in a large diameter cylinder 11 of valve unit body 10, and the second valve assembly 60 comprising a ball 68 and a valve spool 61 slidably received in a small diameter cylinder 12 in body 10; valve assembly 50 has a first normally open valve 50a consisting of ball 58 and a conical surface 57 on spool 51 and a first normally closed valve 50b consisting of an inclined face 56 on spool 51 and a ring shaped edge 25 on seat piston 20; valve assembly 60 has a second normally open valve 60a consisting of ball 68 and conical surface 67 on spool 61 and a second normally closed valve 60b consisting of a conical face 66 on spool 61 and a ring shaped edge 19 between cylinders 11, 12. To operate the unit a brake pedal connected to a push rod 41 is actuated to thereby move a slidable holder 35. This closes the valve 50a to cut off communication between reservoir 80 and wheel cylinder 82 via chambers A and B, and subsequently valve 50b is opened to connect accumulator 88 with wheel cylinder 82 via chambers E and B. The increased pressure in chamber B acts on a holder 30 slidably received in a ring-shaped member 28 fitted into seat piston 20 which in turn acts on the ball 68 to close valve 60a and open valve 60b. Accumulator 89 is thereby connected to wheel cylinder 83. Reaction to the operator is communicated by fluid pressure in chamber B acting on valve spool 51. Should the first circuit fail holder 35 may move seat piston 20 directly to operate the second valve assembly 60. In the modification of Fig. 6 (not shown) the holder (30<SP>1</SP>) is screwed to seat piston (20<SP>1</SP>) so that they always move together. The diameters of the two holders may be the same or different to give identical or differential braking pressures in the two circuits.

Abstract: 1375714 Locks G R PIEDDELOUP 19 Nov 1971 [26 Nov 1970] 53853/71 Heading E2A A locking mechanism comprises a plurality of toothed wheels 17 each of which is engaged by a pawl 21 each wheel having a plurality of angular positions in each of which a respective pawl will retain the wheel and in one of which the pawl releases a locking member 25 for displacement, the wheels being rotatable senatim by a multi position selector dial 1 to their release positions upon dialling a preset sequence of numerals or letters. The dial 1 is connected by a shaft 3 to a disc 8 which is retained by a pawl 9 swivelling on a spindle 11 which also supports the pawls 21 for the toothed wheels 17 freely pivoting on the shaft 3. The first toothed wheel is set by dialling the first numeral or letter of the code thereby turning the disc 8 together with a shaft 12 connected thereto and which engages in a recess in a slider 15 slidable longitudinally relatively to the shaft 3 and depressed by a stop 13 spring urged to engage an abutment on the slider, the slider being connected to the wheel 17 by a rod 20 which turns the wheel. The wheel is retained in the set position by the pawl 21 engaging in a shallower tooth of the wheel. Setting the wheel causes the rod 20 to disengage a recess in the next one of a series of the stops 13 which stop pivots anti clockwise under the pressure of a spring 13b, and depresses the next slider 15 against the pressure of a spring 15B so that the shaft 12 then engages in the recess of the slider when the next numeral or letter of the code is dialled. The abutment projecting from the first slider 15 disengages the first stop 13 which held the first slider 15 depressed, the rod 20 remains in driving position in the slot in the slider 15 under the action of a restoring spring 19 acting on a member 18 connected to the wheel 17 by the rod 20 until the wheel is set when spring 15B raises the slider 15 so that the recess therein is out of engagement with the shaft 12. When the second wheel is set the third slider 15 is depressed to engage the shaft 12 when the third numeral or letter of the code is dialled. By dialling the remaining numerals or letters of the code all the wheels 17 are set so that all the pawls engage in a shallower tooth of the respective wheels and the member 25 is in a releasing position in the L-shaped slots in the pawls. To restore the wheels to their original positions the member 25 is displaced in the slots in the pawls to pivot the pawls to release the wheels which return to their original positions under the action of the springs 19. The stops 13 reengage the rods 20 and are raised to inoperative position, the first stop remains depressed under spring action. The sliders 15 are restored to their original position. The code is changed by turning each wheel 17 a predetermined single relatively to the respective member 18 fixed to the shaft 3 and by inserting the rod 20 in the new aperture in the wheel.
