Abstract: 1,249,897. Centrifugal pumps; Raising liquids. P. RHEINLANDER. Dec. 5, 1968, No. 57800/68. Headings F1C and F1R. [Also in Division C7] In degassing a metal melt by circulating succesive portions of the melt from a container to a vessel situated above the container by means of a pressure difference between the two, the melt is caused to return to the container between successive flows of melt to the vessel, the flows passing between the vessel and container via inlet and outlet pipes and being such that substantially all of each portion is lifted to the vessel via the inlet pipe and substantially all of the raised melt returns to the container via the outlet pipe. In a first embodiment Fig. 1 (not shown), the inlet pipe enters the vessel through a side wall thereof above the level of the upper end of the outlet pipe which enters the bottom of the vessel, and the inlet pipe has a larger cross-sectional area than the outlet pipe. In Fig. 2, the lower end of the outlet pipe 14 is funnel shaped and a ceramic plug 16, less dense than the melt, acts as a oneway valve preventing entry of metal from the container to the outlet pipe when vacuum is increased in vessel 7 or when container 8 is raised during evacuation of vessel 7 or when a positive pressure is applied to the surface of the melt in container 8. In another embodiment, Fig. 4, restriction of upward flow of metal in the outlet pipe may be obtained by providing the pipe with a serrated lining as shown, the serrations being such as to favour downward flow. Alternatively an electromagnetic coil may surround the outlet pipe and is energized to favour downward flow. In a further embodiment Fig. 7 (not shown) the inlet and outlet pipes enter through the base of the vessel and the inlet pipe terminates above the upper end of the outlet pipe. The pipes contain oppositely directed Venturi nozzles so as to favour unidirectional flow and flow is obtained by alternately applying and releasing pressure in the container via an auxiliary container and melt raised to the vessel is degassed by closing a vent valve thereon during periods when pressure in the container is released. In Fig. 8, the foot of the inlet pipe is bent at right angles and either the vacuum vessel or ladle 8 is rotated in such a sense as to tend to drive the melt up the inlet pipe the outlet pipe may have an oppositely directed bend to cause melt to be sucked from the bottom of the outlet pipe.

Title: Metal removal method using an electric arc and gas jet and apparatus therefor
IPC: B23K9/013
Filed: 1973-12-18
Abstract: 1457438 Removing metal by fusion MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 18 Dec 1973 [19 Dec 1972 13 Feb 1973 17 May 1973] 58657/73 Heading B3V [Also in Division H5] In a method of removing a portion of a metal workpieee 2 by an electric arc generated between an electrode 1 and the workpiece 2, the molten metal is blown away by a jet spray formed of a mixture of a non-combustible liquid and a non-combustible compressed gas. When electromagnetic valves 75, 77, Fig. 7, are opened by a switch 35 on the end of an insulating handle 34 of the torch 3 compressed air (or nitrogen or carbon dioxide) is supplied from a compressor 5 through a hose 6 into a water supply device 11, where it passes through the valve 75, a conduit 71 and a conduit 72 where it is mixed with water flowing through a conduit 73 from a water tank 65. The compressed air is also passed into the water tank 65 through a conduit 70 so as to equalize the pressure in the tank 65 with that in the compressed air conduits. The mixture of compressed air and water is passed through a hose 7, passages (43, 48) (Fig. 5, not shown) in a cable 4 and a passage 26, Fig. 3, in the torch 3 to be discharged through jet holes 23 in the end of the torch 3 to form springs 102 which reduce the amount of dust and carbon monoxide released to the environment. The electrode 1, which comprises carbon plated with copper, is locked by a spring biased pin 27 in a hole 22 of a copper head 21 of the torch 3. The electric arc is generated by a power supply 8 having one lead 10 connected to the workpiece 2 and another lead 9 connected to the electrode 1 via an electrical wire (44) within the cable 4 and a fitting (45) at the end of the cable 4 screwed into a fitting 24 of the torch 3. When the valve 75 is closed at the end of the operation, high pressure air in the liquid tank 65 escapes through a valve port 76 and a check valve 80 in a supply conduit 79 is opened to cause the tank 65 to be refilled from a supply tank 66 whose water level is controlled by a valve 82. A further, cleanser, reducer, antirust agent, colouring agent or a perfume may be added to the water. In another embodiment (Fig. 12, not shown) an air jet (105) is surrounded by a curtain 106 of a mixture of water and compressed air. The valves 75, 77 may be automatically opened when the electric arc is generated.

Patent GB-1283759-A (GB)
Title: Recording and reproducing apparatus
IPC: G11B5/004
Filed: 1969-12-24
Abstract: 1283759 Recording and playback INTERNATIONAL BUSINESS MACHINES CORP 24 Dec 1969 [14 Jan 1969] 62809/69 Heading G5R Consecutive strokes of relative reciprocation of a recording and playback head 15, and a record member (14, Fig. 1) in the X + and X - directions are separated by steps in the Y + direction under the control of an escapement having two states associated respectively with the two directions of stroke, the change from one state to the other producing the step between two strokes; the escapement may be overridden to allow manual operation, but its state at the end of manual operation is determined by the direction of stroke. This ensures that the head is aligned with a record track appropriate to its direction of relative movement. As shown, the magnetic head 15 is reciprocated across a record card (14) by means of a double-threaded lead screw 21 driven by an electric motor 26, the reversal of movement at the end of each stroke being initiated by a resilient bumper 33 or 34. Near the end of each stroke a projection 73 on the head carriage 20 causes a bar 52 to move in the same direction so that an extension 50 changes the state of an escapement (Fig. 3) comprising two pawls 40, 41 alternately engaging a toothed rack (42), allowing a spring motor 38 to move the support frame 25 by one step in the Y+ direction. Actuation of a lever 19 withdraws both pawls 40, 41 from the rack (42) to permit manual movement of the head assembly in the Y+ or Y- direction, but the bar 52 continues to respond to the reciprocation of the head in the X directions and thus determines the state of the escapement when the lever 19 is released. Alternative forms of the escapement and its triggering mechanism are described, and in one embodiment (Figs. 4 to 7) the relative movement in the Y directions is produced by a sprocket drive of the record card, which may be bent to follow a closed path (Fig. 7), the driving spring being wound by the loading of the card into the apparatus.

Title: A device for measuring the displacement of an image
Inventor: VOLKOVISKY VICTOR
IPC: G01S3/784
Filed: 1969-12-31
Abstract: 1,261,290. Position measurement. COMPAGNIE DES COMPTEURS. 31 Dec., 1969 [31 Dec., 1968; 4 July, 1969], No. 63609/69. Heading H4D. [Also in Divisions G4-G6 and H1] A device for measuring the cartesian coordinate displacement of the image 10, Fig. 1 of an object emitting infra-red radiation, e.g., the Earth's disc, in relation to an origin 0 defined by the device, comprises a plurality of thermocouple junctions 1 to 2n for each of the axes X and Y, so arranged and connected that voltages are produced at terminals 21, 23 and 22, 24 respectively proportional to the X and Y image displacements. In the device of Fig. 1 junction groups 11 and 13 are arranged along the X axis and symmetrically either side of the origin 0. The junctions 1 to 2n are connected in series in the order: 1, n+1, 2, n+2, 3, n+3 ... n, 2n, junctions 1, 2, 3 ... n, producing voltages of opposite sign to those from junctions n+1 ... 2n. The connections 17, 18 etc. are comprised of Antimony 17 and Bismuth 18 conductors vapour deposited on a thin substrate sheet 15 supported by a ring 16 and the junctions are produced at contact points between the antimony and bismuth conductors. The optics of the device is so constructed that the image 10, when centred on origin 0 covers exactly half the junctions of group 11 and half those of group 13. In this case the opposing voltages of the junction groups cancel out and zero voltage appears at terminals 21, 23. As the image moves from the central position along the X axis the sum voltage from one of the junction groups will supersede that from the other and a displacement indicative voltage will appear at the terminals. A similar pair of junction groups 12 and 14 provides for Y dispiacement indicative voltages at terminals 22, 24. The junction groups are each covered with a layer of infra-red radiation absorbent gold/black (dotted rectangles) such that the sharp transition of temperature at the edge of the image is smoothed over and the output terminal voltages, which would otherwise be discretely variable, become continuously variable. In the device of Fig. 2, however, the layers 1A, 2A etc. of infra-red absorbent do not extend from one junction to the next, and the output terminal voltages retain their discrete variability. In the device of Fig. 3, there are four X co-ordinate junction groups 11A, 11B, 13A, 13B parallel to the X axis and connected in series opposition, and the two Y co-ordinate junction groups 12 and 14 and each curved to conform to the shape of the image. This arrangement of junction groups enables a smaller amount of interconnecting Antimony and Bismuth to be used. Whole junction group layers of infra-red absorbent ensure continuous displacement indicative voltage outputs.

Patent GB-2012913-A (GB)
Title: Gas Spring
IPC: E05F1/10
Filed: 1979-01-19
Abstract: A gas spring comprises a cylinder (1) which is closed at one end and within which a piston (2) works, the piston being carried by a piston rod (3) extending sealingly through the other end of the cylinder. The cylinder contains gas and liquid and the piston has passageways (12, 13) which permit the passage of liquid from one side to another of the piston. To overcome the problem of known gas springs in which the passageways restrict flow in both directions and in which substantial effort may be required to overcome the resistance of liquid passing through the passageways when compressing the spring, which is disadvantageous for example when the spring is supporting a vehicle tailgate, a restrictor plate (9) is provided which co-operates with the passageways (12, 13) and is arranged to restrict the flow of liquid through the piston (2) during an extension stroke of the spring and to permit substantially unrestricted flow during a compression or retraction stroke. <IMAGE>
