Abstract: 1,239,148. Stabilizing load handling vehicles. E. WINTER, A. WINTER, E. WAGNER, R. WAGNER, F. KEIM, and L. WAGNER, [trading as ERNST WAGNER APPARATEBAU]. 27 March, 1969 [18 April, 1968], No. 16042/69. Heading B7D. [Also in Division B8] In a fork lift truck having two chassis parts 4, 5 which are adjustable to vary the truckwheelbase, and a load carrying platform 10 carried by a mast 11 pivoted at 16 to the chassis part 5 so that a load 15 on the platform 10 produces a moment about the pivot 16, the moment is measured by a force measuring device which blocks the action of a drive for lifting and/or travel of the truck until the wheel base is appropriate to the load, and the truck has a drive for wheel base adjustment which is either manually activated, or activated automatically in response to the measured force. The wheel base adjusting drive comprises a piston 7 and a cylinder 6 connected to the chassis parts 4, 5 respectively. The force measuring device comprises a piston 13 connected to the mast 11, and a cylinder 12 carried by the chassis part 5. An hydraulic feed conduit 35 connects the cylinder 12 with a series of electrohydraulic switches 21, 22, 23 which act in an electric circuit 19 for the drive for lifting and/or travel. Thus a switch will break the circuit 19 until the wheel base drive has been manually activated to cause a bar 24 on the chassis part 5 to return the respective switch and re-close the circuit 19. In another embodiment (Fig. 3, not shown) the electrohydraulic switches are change over switches and are also connected in the circuit (26) for wheelbase adjustment, so that when an excess load is sensed the circuit (20) is closed and the circuit for travel is opened. The switches being switched over when the appropriate adjustment has been effected. In another embodiment (Fig. 4, not shown) an hydraulic ram (32) connected in the conduit 35 blocks movement of a manual control lever (29) for the wheel base drive so as to provide, for a certain load, a lower limit beyond which the wheel base cannot be reduced.

Abstract: 1,257,355. Granulating reactive metals. REACTIVE METALS Inc. May 5, 1969 [May 3, 1968], No. 22835/69. Heading C7X. Miscellaneous pieces of reactive metal (e.g. Ti, Zr, Hf or alloys based thereon) are converted to a useful form for making up a melting charge by feeding them to a water-cooled hearth from which gases that react with the metal are excluded, melting the pieces in said hearth, discharging a stream of molten metal from said hearth, dispersing said stream, and solidifying the resulting dispersed particles in the form of pellets and/or flakes. A suitable apparatus is shown, wherein chamber 10, filled with an inert gas such as argon, houses a water-cooled hearth 12 on trunnions 13, tiltable by means 15. Miscellaneous pieces of metal M are fed from bin 17 into air-tight chute 18, assisted by vibratory feeders 19 and 20, the chute having two air-locks 21 and 22, only one of which can be open at any one time. Pipes 23 and 24 supply chamber 10 and chute 18 with inert gas, or are connected to vacuum. Metal passes to the hearth, where it is melted by an arc from electrode 26, any solid dense inclusions D in the metal sink to the bottom of the melt, and liquid metal overflows at 33 and falls in a stream on to rotating spoked wheel 38 so that flakes F and pellets P collect on the floor 35 of the chamber, whence they may be removed via exit chute 46, water-cooled by pipes 51 but otherwise similar to chute 18, above.

Abstract: 1,264,489. Moving coil meters. AGFA GEVAERT A.G. May 9, 1969 [May 11, 1968], No.23729/69. Heading G1Q. A moving coil meter structure incorporating a central core magnet is such that the magnet can be removed from its operative position within the coil, without disturbing the coil. The coil 5 is mounted within a tubular magnetisable housing 1 by insertion through an opening 6 in the housing. The coil bearings are on bridge pieces 2, 3. The central core magnet 11 is mounted on an arm 9 which can be inserted into the housing through an aperture 7 on the opposite side to the opening 6. The arm has extensions 9a with shaped ends which precisely locate the arm relative to the housing aperture. The arm is attached to an insulating support which enables it to be bolted in position on the outside of the housing by screw 14. The support carries a contact 16 connected to an arm 17, which enters the aperture 18 in the housing 1 when the arm is put in the operational position. The arm 17 is connected to the spiral spring of the meter movement to provide an anchor and electrical return therefor. The arrangement shown enables the coil to be withdrawn through the opening with the magnet in position. The same aperture may be used for both coil and magnet, but in that case, the coil may not be separately withdrawn.

Abstract: 1295505 Plotting photographic density contours KONISHIROKU PHOTO INDUSTRY CO Ltd 24 Sept 1970 [4 Oct 1969] 45635/70 Heading H4F When a photograph is scanned in two dimensions and spatially equivalent points are plotted whenever predetermined density levels are reached, to give a contour map, if the contours for alternate density levels are distinguishable e.g. by being formed of light and heavy dots in Figs. 4 and 6, it becomes possible to distinguish density distributions such as these shown in the corresponding Figs. 3 and 5 which would give identical maps were the contours unlabelled, Figs 1 and 2 (not shown). If additionally one line corresponding to a reference density level is different from all the rest (double dots), a quantitative estimate of the local density level becomes possible. One apparatus for providing such maps, Fig. 8 (not shown), comprises a series of circuits each receiving the signals from the photograph scanner and providing an output pulse when the signal reads a corresponding one of a series of different levels. The circuits are connected alternately to amplifiers with relatively high and low amplification factors and which provide large or small pulses to control an electric discharge element for plotting the dots. One circuit for the reference level, however, is connected instead to an amplifier which produces two pulses for each input pulse. Reference is made to prior art wherein a plurality of pens provide contours of different colour or intensity.
