Abstract: 598,291. Artificial legs. MORTENSEN, L. L. Oct. 27, 1943, No. 17738. Convention date, Sept. 12, 1942. [Class 81 (ii)] An artificial leg, comprising three members pivoted together at 16 and 18, is provided with a knee brake formed by a shoe member 54 and a drum 56 which are brought into resilient contact by means of link mechanism 60, 66, 74, 86 and springs 59, 61 when the toe portion of the foot member is moved downwardly relative to the lower leg member. The relatively strong spring 61 ensures a smooth operation of the brake, while the weaker spring 59 returns the brake shoe to the inoperative position. An adjusting link may be provided as shown at 72, or in the rod 74. The lower leg member may be formed in two portions 20 and 24 which telescope together and between which spacing washers 30 are provided to vary the length of the leg. The portion 20 and the foot member connected thereto may swivel relatively to the portion 24, the normal alignment being restored by a spring or rubber block. In a modification, Figs. 9-]2 (not shown), the brake drum is constituted by a U-shaped member, the ends of which encircle the knee bolt and are provided with split rings adjustable to tighten or loosen the knee joint ; in this modification also the spring 59 is replaced by a spring, or resilient device comprising a block of compressible material, in the rod 74.

Title: Two-stage rotary vacuum pumps
Inventor: WYCLIFFE HENRYK
IPC: F04C23/00
Filed: 1967-09-21
Abstract: 1,248,031. Rotary vacuum pumps. EDWARDS HIGH VACUUM INTERNATIONAL Ltd. Sept.19, 1968 [Sept.21, 1967; April 16, 1968], Nos.42965/67 and 17810/68. Heading F1R. A two-stage rotary vacuum pumping unit comprises a lubricator low vacuum stage having first and second co-operating pumping components, a "dry" high vacuum stage having third and fourth co-operating pumping components and means connecting the two stages whereby relative movement between the first and second pumping components results in driven corresponding in phase movement of the third and fourth pumping components and in which the third and fourth components cooperate without contact therebetween. The two stages are preferably of identical type but this is not essential. High and low pressure vacuum stages 2, 6, Figs. 1 and 2 have indentical rotors 16, 8 fixed to a common rotatable shaft 9 with a clearance between the rotor 16 and its housing. The rotors which are eccentrically mounted in the pump housing co-operate with identical hinged abutments 17, 10 fixed to a common shaft 11 and urged by a torsion spring 12 into abutment with the rotors. The shafts 9 and 11 are each provided with a pair of bearings 13, 14 respectively beyond each of which is an oil seal 15 inhibiting the leakage of oil from the oil-filled low vacuum stage 6 and the penetration of oil into the non-lubricated ("dry") high vacuum stage 2. The rotor 16 and its abutment 17 may be coated with p. t.f.e. whence the rotor 16 engages the housing. The shafts 9, 11 in the high vacuum stage may be overhung, as shown for the shaft 9, or supported by a "dry" bearing 20, as shown for the shaft 11. An interstage trap 4 connected by passages 3, 3a to the outlet and inlet of the high and low vacuum stages respectively is filled with activated alumina to inhibit the migration of oil vapour towards the high vacuum stage. The trap 4 which absorbs moisture is positioned between the stages to reduce pumping against water vapour pressure which would occur if positioned at the inlet 1. To reduce moisture absorption in the trap, the passage 3 is fitted with a pressure relief valve 25, Fig. 3 adjacent the high vacuum stage outlet and a diaphragm valve 28 formed with an aperture 29 upstream of the trap. During initial pumping, pressure is sufficient to unseat the valve 25 through which the pumped medium passes directly to atmosphere whilst closing, except for the aperture 29, the valve 28. As pumping proceeds, the valve 25 closes and the valve 28 opens by suction with the pumped medium then passing through the trap 4 and the low vacuum stage. The abutments 10, 17 may be made of light weight material, e. g. plastics material or aluminium alloy to minimize vibration. In a modified construction, the two stages are shown with each having a pair of intermeshing screw rotors.

Title: Improvements in or relating to barrel locks
IPC: E05B21/06
Filed: 1927-07-06
Abstract: 276,964. Soc. Bournisien, Beau, et Cie. Sept. 6, 1926, [Convention date]. Locks, revolving-barrel.-A locking mechanism adaptable to a master key system comprises a built-up outer cylindrical casing and an inner coaxial rotatable barrel in which the sliders, operated by a rotatable key inserted axially, each slide radially in one of two opposite directions to engage or disengage the outer casing. The outer casing is composed of a head 2 and a cylindrical wall 3 with slots 6, 7 and an end plate 4 secured thereto by screws and serving to clamp an outer sleeve 1, which encloses the moving parts. The ward plates 33, 34, Fig. 5, are carried by and slide radially in a slotted cylindrical barrel 12, integral with a tubular extension 22 which is free to rotate in the outer member when all the plates 33, 34 are withdrawn from the slots 6, 7 and lie concentric with the barrel. A pin in a groove in the side of the inner cage 12 limits the radial motion of the plates in one or other direction by co-operation with slots 39, 40 in one of the straight sides of the plates. The asymmetrical wards 33 normally lock the barrel and are moved by ridges 50 on one side or the other of the key stem 49, Fig. 6, according as they are set to be moved to right or left to unlock the mechanism. A ridge on the wrong side of the key will tend to move a ward further into the locking position. The locking device may be adapted for actuation by a particular key or by a master-key by the inclusion of symmetrical wards 34, which are normadly concentric with the barrel 12 but are moved outwardly by a wrong key having, a ridge opposite thereto. Each lock of a series has a series of wards 34 in particular axial positions; in each lock at least one of these wards has no projections 46 and its particular key has a ridge to coact with the special ward or wards but has grips 51 opposite the other wards 34 in order that none of these may be moved when the key is used for its own lock. Any other key of the series will have a ridge opposite at least one of these wards 34 with projections 46 and will fail to release the lock. The master key has a series of gaps opposite each ward 34 and therefore can release any one of the locks.

Title: Improvements in pumps for hydraulic gears, lifting machines, hydraulic presses and the like
IPC: F04B49/12
Filed: 1926-07-21
Abstract: 255,869. Hardt, A. July 23, 1925, [Convention date]. Eccentric-actuated pumps; stroke-varying mechanism.-The delivery pressure of pumps used for supplying hydraulic gear, lifting-machine, presses, &c. is automatically controlled so that the delivery varies inversely as the delivery pressure whereby the load on the driving-motor is constant. A radial pump a has an eccentric track b the position of which is varied transversely by the delivery pressure. The track b is connected to pistons f, h on a common rod with a plunger extension o. The piston f is subject to delivery pressure, and the left-hand side of the piston h to air pressure supplied past a non-return valve m from a reservoir n. The pressure of air is to the pressure of the oil or liquid pumped at maximum delivery as the area of the piston f is to the area of the piston h. Variations in delivery pressure affect the track position until a balance is effected. Pressure may be supplied to the extension o under the control of a handcock r to reduce the load on the driving motor as, for example, when starting a motor car. The air mechanism may be replaced by a spring or weight acting through a cam.
