Title: Improvements in and relating to balancing machines
IPC: G01M1/04
Filed: 1938-06-13
Abstract: 505,323. Testing balance of rotary bodies. SCHENCK EISENGIESSEREI UND MASCHINENFABRIK DARMSTADT, GES., C. June 13, 1938, No. 17524. Convention date, June 14, 1937. Addition to 451,907. [Class 106 (ii)] Relates to a machine wherein the body to be balanced can be made to oscillate in relation to a freely adjustable axis by connecting the body with an auxiliary shaft having an adjustable axis of oscillation, and consists in connecting each of the two bearings of'the body to an end of the auxiliary shaft through an intermediate shaft parallel to the axis of the body and capable of being connected with: the bearings of the body at any point to which the bearings may be displaced. The ends of the body a to be balanced run on rollers b mounted on rocking supports c, d pivoting about axes e and held in position by springs f. The lower ends of the supports c, d are linked by rods g, h to short levera i, k on shafts l, m rotating in bearings in the framework. The levers i, k may be moved along the shafts but must rotate therewith. Further levers n, o on the shafts are linked with rocking levers p, q respectively pivoting on an axis r and their other ends transmit the oscillations to the ends of a shaft s and through rods t, u to the ends of a rod v. Arranged along this rod v are one or more displaceable axes I; II. Only one of these can be brought into action at once and then the rod v is forced to oscillate in relation to the fixed pivotal point determined by the said axis. By moving the position of the axis of oscillation I the plane of the axis about which the body a oscillates can be determined. To ensure the body rotating about an axis perpendicular to its axis of rotation and in the plane II at the left hand face it is only necessary to move the axis of oscillation on rod u to the position II. Similarly for the right-hand face I the position I on the rod v is correct. The shaft s carries a disc w with a counterweight. This disc may be slid longitudinally on the shaft s but rotates with it. The shaft x of the body to be balanced transmits motion through the shaft r to a pulley z mounted on the shaft a. A device y is provided by means of which phase displacement can be measurably varied. By adjusting the device y and moving the disc w the out of balance forces may be compensated. All the controls for adjusting the axis of oscillation and for testing balance can be arranged at one convenient point.

Title: Fluid flow regulators
Inventor: ROBERTSON DAVID MILLER
IPC: A47H1/10
Filed: 1966-04-22
Abstract: 1,179,835. Fluid-pressure servomotor systems. BRITISH OXYGEN CO. Ltd. April 21, 1967 [April 22, 1966], No. 17698/66. Heading G3P. The flow of fluid from a source under pressure to an aviator's G garment is controlled by a valve member in the form of a flexible annular diaphragm 14 which sequentially uncovers a plurality of orifices 16 under the control of a member, such as 68, responsive to changes in gravity loading. The member consists of a weight which is normally urged away from engagement with the seat at the upper end of a double-ended valve member 61 by a spring 69 until gravity loading increases when the weight restricts the escape to atmosphere of fluid, such as oxygen, through an orifice 51 causing a pressure build-up in a chamber 34 above a diaphragm 29 to open a relay valve 24 against the resistance of a spring 31. Oxygen now flows through an orifice 20 to lower the pressure in a space 18 at one side of the diaphragm 14 which is lifted by the pressure in a passage 17 communicating with the inlet 11. Further increases in gravity loading increase the pressure in the chamber 34 proportionally until the lower end of the doubleended valve member 61 is separated from an annular seat 64 against the resistance of a spring 63 so that subsequent increases in gravity loading cause a lower rate of pressure increase in the garment. The pressure required to lift the valve member 61 from the seat 64 may be increased by turning a secondary weight 82 through 90 degrees so that its inward movement is not limited by stop pins 84 and flow of oxygen through a second doubleended valve member 75 is restricted to increase the loading on the member 61. At a predetermined pressure, the member 75 lifts against the resistance of a spring 77 to again reduce the rate of increase of pressure in the G garment with increase of gravity loading. To enable the valves 14 and 24 to be tested in the absence of increased gravity loading, a piston 55 is pressed inwards to stop the flow of oxygen through a port 54 to atmosphere. Oxygen is dumped from the garment when the pressure in chamber 34 falls by a diaphragm 39 uncovering both a central orifice 43 leading to the outlet 12 and a plurality of smaller orifices 44 leading to atmosphere. In a modification, each weight is arranged to give the required performance independently of the other and is housed in a chamber having a vent connected to atmosphere by a manually-actuated valve which is spring-loaded so that it remains in one of its two operative positions. In a further modification, a single weight co-operates with a double-ended valve member to which a spring-loaded weight may be coupled by a manually-actuated cam mechanism to alter the characteristic of the device.

The breaker is however held closed by the engagement of lugs 16 on a gravityactuated bridge 15, pivoted to shaft 14, with notches 18 in slots 17, and the button 1 is held depressed against the action of spring 23 by engagement of the lower edge of slot 4, 5 with the locked shaft 14. The breaker is opened by further depressing the button, as allowed by slot-part 5, surface 6 on catch 3 breaking the toggle 10, 11, which thereupon engages the bridge 15 to free it, and the parts being returned by spring 23 when the button-pressure is removed. A trip force at 26 can also produce opening. Indicators.-When the catch 3 is moved to and fro, a plate 20 bearing legends moves behind an aperture 21 in the button.

Abstract: 813,275. Mould core materials. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. May 29, 1957 [June 8, 1956], No. 17809/56. Drawings to Specification. Class 83 (1). A method of making a casting with a cored hole therein comprises using a core formed of a material which can be oxidized in contact with atmosphere at a temperature at which the casting is substantially unaffected, and having a continuous outer coating of a material capable of withstanding the casting temperatures, the core being removed after solidification of the casting by breaking the continuity of said outer coating and heating the casting at a temperature such that the underlying material is oxidized, but the casting is unaffected. The core is preferably of molybdenum or its alloys, and in tubular form with an outer coating of molybdenum silicideapplied by a siliconizing process. Other cores materials are niobium, tungsten, tantalum and alloys thereof, and graphite or graphitic material. As applied to the manufacture of a gasturbine blade having cooling passages therethrough, by the lost-wax process, the tubular cores with ends closed by pinching are embedded in the wax pattern as shown in Specification 710,334, which is referred to, and the ends of the cores may be broken away with the mould after solidification. Alternatively cores whose ends remain intact may be broken off, or the refractory coating scraped or filed. The casting is then heated to 700-800‹ C. to oxidize the molybdenum core and vaporize the resultant oxide, without affecting the casting.
