Title: Improvements in and relating to Artificial Legs.
Inventor: SCHRANZ PAUL
IPC: A61F2/60
Filed: 1918-05-24
Abstract: 126,887. Schranz, P., and Schranz, R. May 24, 1918. Limbs, artificial.-Comprises a special construction of apparatus for effecting the locking of a knee-joint through the instrumentality of a band brake, actuated by relative movement of the jointed parts when the weight is thrown on the leg. In the present construction, the band c3 has a spring connexion with the leg at the lower end and a guided sliding connexion with the thigh at the upper end. The brake comprises a fixed jaw d* and a pivoted jaw d actuated by a lever c connected by a link a<2> with the knee-joint pivot. When the weight is thrown on the leg, the pivot moves downwardly in the slots h<1>, and tends to rotate the lever c. During this operation, the periphery k<3> of a wheel acts as a fixed abutment for a pin k<2> on the lever, which thus fulcrums about this pin and moves the jaw d into its acting position against the action of the spring m<6>. When the sound leg is moved forward to take a step, the consequent bending of the body is used through body harness to actuate a cord m<5>, and thus rotate a lever m<2> against the action of a spring m<3>. This action allows the wheel to move to the upper end of its slotted bearing k<5>, thus releasing the pin k<2> and allowing the jaw d to be restored by the spring m<6>. The artificial leg, being thus unlocked, is lifted to take a step, and the leg portion falling by gravity relatively to the thigh portion restores the lever c to its original position ready for the succeeding step. The strain on the cord m<5> is also released and the lever m<2> restored as the artificial legs is moved forward.

Patent GB-1056336-A (GB)
Title: Improvements in rolling mills having hydraulic pressure control
IPC: B21B37/64
Filed: 1964-04-16
Abstract: 1,056,336. Rolling. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (ST. CHAMOND - FIRMINY - ST. ETIENNEJACOB-HOLTZER). April 16, 1964 [May 13, 1963], No. 15846/64. Heading B3M. A rolling mill is provided with an hydraulically adjustable upper roll, each end of the roll being controlled by a ram whose pressure is controlled by a slidable motor-driven spool valve. For extreme pressure conditions, as when a workpiece is first introduced between the rolls, the conduits of the valve are connected by a switch to further hydraulic rams which counteract the increased pressure. Each end of a roll 30 is positionally controlled by a ram P in a housing 1, a support 36 being attached to the two housings. In each housing is a slide valve 15 whose vertical position is controlled by a reversing motor 3 via a differential 4 and gearing 16. The motor 3 can be controlled by servo means to keep the rolling press constant. Conduit F above ram P is normally connected via conduit D and the valve 15 either to a pressure supply, through conduit E, or to waste, through conduit C depending on the position of the valve. Independent positional control of the valve 15 may be effected by rotation of the casing of differential 4, and this can be made dependent on the strain measured in the mill frame or within chamber 22, so that mill spring can be compensated for. When commencing rolling a switch automatically connects conduit E to conduits A and B of further coaxial rams 19 and 17, instead of to conduit F. When three rams are supplied with pressure fluid rams they move downwardly and urge ram P downwardly under increased pressure. Wormgear 13, which acts on the ram 19, can be used automatically to compensate for increased pressures. The pressure multiplier may have 2 or 4 or more stages in place of the 3 shown. The ends of the roll has transverse pins attached to them which can pivot in bearings to allow bending of the rolls. This prevents damage if the two rams P do not act to precisely the same degree. The bearings for the pin are pivoted to allow removal of the roll.

Title: Improvements in and relating to fluid controlling valves
Inventor: SHAND STANLEY G
IPC: F16K5/20
Filed: 1953-06-09
Abstract: 761,977. Valve accessories. SAUNDERS VALVE CO., Ltd. June 9, 1954 [June 9, 1953]. No. 15882/53. Class 135. A rotary, spherical plug cock has seating rings 13 supported in the casing by flexible diaphragms 14 and counterbored at 16 so that fluid pressure has access to the plug sides of the rings to provide a resultant thrust in opposition to but less than the pressure of springs 17 which are housed in pockets 18 in metal rings 19. Fluid pressure on the major part of the diaphragms is rendered ineffective by washers 15. Excessive pressure on one side of the valve can force its way between the corresponding seating ring and the plug to the central valve chamber whence it can escape by displacing the diaphragm on the low pressure side of the valve. Specifications 571,285 and 655,078 are referred to.

Title: Apparatus for controlling draft
IPC: F23L17/00
Filed: 1945-06-23
Abstract: 594,042. Draught regulation. McINTOSH, R. R. June 23, 1945, No. 16064. [Class 51 (i)] Apparatus, for controlling the draught in a locomotive smoke box, of the kind comprising two or more valve-controlled conduits connecting the smoke box with the atmosphere, is characterized by regulable means which positively hold closed the valve or valves of those conduits, which normally open at the lower vacuum conditions in the smoke box, the draught being thus regulable according to cutoff or fuel feeding conditions. As shown the admission of air to the smoke box is effected through inlets 10, 11, the valve 26a of the latter being arranged to lift at a predetermined relatively low excess of atmospheric over smoke box pressure, whereas the valve 26 of the former is arranged to lift at a predetermined higher excess which is the maximum permissible excess. If cut-off or fuel feed conditions require a pressure excess greater than is normally permitted by the valve 26a, this valve is kept closed by a presser 35, 36 operated by a piston 90 in a cylinder 34 supplied with steam or, preferably, with compressed air. The air.supply pipe 38 connects through a reducing-valve 39 and pipe 40 to the lower part of the cylinder 34 and normally keeps the piston 90 raised. If, however, the cut-off is increased beyond a predetermined per-centage by operation of the handle 44, a cam 47 opens a valve 42 to admit full pressure air to the top of the piston 90 which is thus depressed. The air confined in the lower part of the cylinder 34 is vented through a valve 48. The piston 90 may be actuated, alternatively, by opening the valve 53, this being effected by connection to the fuel-feeding means, e.g., by a rod 52 connecting the valve 53 with the valve 51 controlling the supply of. steam to a stoker engine. The rod 52 has a lost motion connection with the lever 54 of the valve 51 so that a predetermined fuel feed rate would have to be reached before the valve 26a is kept closed. The control of the valve 26a may be effected by a manually-operated valve 49, in which case the valve 50 would be closed. In a modification, three air inlets are arranged in a conduit running across the smoke box. The inlets each have a valve similar to the valves 26, 26a, the centre valve controlling the maximum vacuum, and the other valves controlling a low and intermediate vacuum level respectively. The two latter valves are controlled in accordance with the cut-off or fuel-feed rate, a cam-operated valve 42 being provided for the compressed air control cylinder of each of said two valves. The cams operating the valves 42 are arranged to open the valves at different percentages of cut-off. An electric control may replace the fluid-pressure controls described above, in which case the cylinders or cylinders 34 is replaced by a solenoid, or solenoids, which project the presser 35, 36 when energized, but allow the valves 26a to open when de-energized. The cam 47, in this case, operates a switch when a predetermined cut-off is reached.
