Title: Lubricant quantity regulators for centralised pressure  lubrication installations
IPC: F16N25/02
Filed: 1971-05-18
Abstract: 1358201 Lubricating TECALEMIT SA 18 May 1971 15576/71 Heading F2A A lubricant quantity regulator for a centralized pressure lubrication system includes a lifting valve comprising a movable rigid-bodied valve member 6 in a housing 1 having an inlet orifice 14 through which lubricant coming from a pressurized supply line A enters the housing and proceeds to a metering device 2, the housing having an outlet orifice 8 through which lubricant, which returns to the housing while being dispensed by the metering device with the supply line unpressurized, leaves the housing on route to a point of lubrication. The arrangement is such that the pressure of lubricant from the supply line when pressurized causes the valve member to close the outlet orifice and to allow lubricant to proceed to the metering device, the pressure of lubricant returning to the housing causing the valve member to open the outlet orifice. The valve member serves to prevent returning lubricant reaching the supply line. The valve member may have a passage through it which facilitates passage of lubricant from the supply line to the metering device, the passage having a valve which prevents lubricant returning to the supply line.

Title: Improvements in the depth regulation of tractor-carried ground-working implements
IPC: A01B63/111
Filed: 1945-06-19
Abstract: 599,020. Agricultural implements. ABBEY, A. (Aktiebolaget Overums Bruk). June 19, 1945, No. 15645. [Class 6 (i)] In an arrangement for the depth regulation of ground-working implements carried adjustably on a tractor, the working tools being capable of yielding backwards against the action of a spring arrangement while operating on a hydraulic level control device, a frame carrying the tools is provided with means adapted in one and the same position of the level control device to relieve the tools from a part of the spring action increasing with their working depth. The carrier comprises a pair of arms 6 upon which is mounted the tool frame 2. The arms are raised by a hydraulic level control device, through link 7 and lever 8, operated by rod 17 against the pressure of a spring 23 adapted to counteract the yield of the tool with a constant force. A spring 28 mounted on a skid 26 opposes the spring 23 with a force varying with the depth of the tool. If the rearward thrust on the tool increases, it will yield against spring 23 and operate the control device through rod 17 to lift the arms 6. This will decrease the effective force of spring 28 so that balance is attained and the lifting movement ceases with a small variation in the position of the tool. In a modification, the skid may be mounted on a two-armed lever pivoted at the front of the frame 2 and having one arm co-operating with a sleeve mounted on lever 22, preferably in two parts. For adjusting the pressure of the skid against the ground, a handle is provided for varying the angle between the two arms of the lever. The skid may be replaced by a ground wheel.

Title: Jet propulsion engine with fuel injection
IPC: F02K7/00
Filed: 1964-04-15
Abstract: 1,066,236. Hydraulic jet propulsion apparatus. KEMENCZKY ESTABLISHMENT. April 15, 1964 [April 16, 1963 (2); May 24, 1963], No. 15674/64. Heading B7V. [Also in Division F1] A jet propulsion engine, e.g. for watercraft, comprises a combustion chamber 3, ignition means 15, a thrust tube 9 having water inlet and outlet openings, a valve 10 connecting the thrust tube and the combustion chamber and a precombustion chamber 2 provided with an injection means 6 which is in communication with a fuel pump 1 arranged to be activated by the pressure in the thrust tube 9. As shown, to start the engine, combustion chamber 3 is filled with an explosive mixture via pipe 20. The mixture is then ignited by spark-plug 15 and creates a high pressure which blows the water out of thrust tube 9 and also moves a disc 12 and piston-rod 14 upwards against spring 13. This allows the liquid fuel from pump cylinder 19 to flow via pipe 5 to nozzle 6 for injecting into precombustion chamber 2. A vortex ring 7 mixes the fuel with air from intake 8 which can be regulated by sleeve 17. After each ignition and after the ejection of water from the thrust tube 9 a partial vacuum arises in the combustion chamber 3 opening check valve 4 to suck the mixture from precombustion chamber 2. This mixture is again ignited and water which has entered the thrust tube at inlet valve 11 is again ejected. In a modification, Fig. 5 (not shown), disc 12 and piston 14 are replaced by a turbine wheel arranged at the outlet of the thrust tube which drives a rotating fuel pump. The turbine wheel is also shown driving an impeller to speed up the filling of the thrust tube with water after each explosion.

Rolls 18 are accommodated in recesses in the periphery of support 38, and are slidable along shaft 21. When the belt 14 moves off-course, the detection device causes a solenoid 29 and lever 31 to move the right or left cam 26 which slides one of the rolls 18 along the shaft 21 and corrects the deviation of the belt; the displaced roll being returned to its original position by one of the fixed cams 25. The belt 14 may be made of woven fabric or wire gauze. Filter cake is discharged from the belt by roll 16. The deviation detection device of belt 14 comprises a pair of tubes 33 (Fig. 6), positioned on either side of the belt, each tube housing a slidable rod 35 terminating in a micro-switch 37 at one end and a detecting plate at the other end. When the filter belt 14 deviates to the right or left above a predetermined distance, it touches the right-hand or left-hand detecting plate and the corresponding micro-switch 37 is closed thereby actuating the corresponding solenoid 29 and cam 26, whereby each of the rolls 18 is displaced in the left or right direction so as to correct the deviation of the belt.

Title: Improvements in and relating to starters for internal combustion engines
IPC: F02N7/00
Filed: 1947-06-16
Abstract: 624,223. Elastic-fluid turbines. BRITISH THOMSON-HOUSTON CO., Ltd., GRAHAM, D. H., FORSLING, B. E. G., and TABBERER, G. June 16, 1947, No. 15814. [Class 110(iii)] [Also in Group XXVII] In starters for internalcombustion engines as described in Specification 517,844, [Group XXVII], in which either gases under pressure, formed by burning a cartridge, or compressed air, are utilised in a starter motor of the turbine type which is connected to the engine shaft through gearing and an automatic engaging and disengaging device, means are provided to reduce or shut off the supply of gas to the starter rotor at a predetermined speed to prevent overspeeding of the rotor, the means being operated by the rotors or some other members rotating at the same or proportional speed thereto when the increase in diameter of the rotor or members which occurs with increase of speed reaches a value corresponding to the predetermined speed. A starter turbine rotor 3 stretches upon attaining an abnormal speed and contacts a shutter 7, normally held stationary in a casing 2 by a friction disc or shear pin, (not shown), and causes the shutter 7 to rotate until its further movement is prevented by stops, (not shown). Axial holes 6 are provided in the shutter 7 which upon rotation of the latter shut off the working gases which normally flow to the rotor 3 through one or more inlet nozzles 4. A relief valve or bursting disc, (not shown), permits escape of the working gases to atmosphere. In a modification, a disc member, driven from the rotor shaft either directly or indirectly through gearing, actuates the shutter before stretching of the rotor occurs. In a further modification, the disc member contacts rollers journalled on the shutter. In another modification, the shutter is replaced by a ring in the casing and stretching of the rotor rotates this ring a limited amount which latter member through a cam form on its periphery, actuates plungers and rocker arms to operate relief valves that by-pass the working gases from the starter turbine. The ring may be replaced by the shutter and actuated by a disc member, instead of the rotor, either directly or through rollers. The shutters may incorporate a cam form which actuates plungers and rocker arms that in turn operate a switch and prevent the firing of further cartridges. The plungers may also be used to indicate the position of the shutter.
