Title: Transport installation for cast moulding boxes
IPC: B22D33/00
Filed: 1952-06-30
Abstract: 740,084. Foundry plant; moulding-machines. BUDERUS'SCHE EISENWERKE. June 30, 1952 [June 30, 1951], No. 16467/52. Class 83 (1). [Also in Group XXX] In foundry plant for transporting poured moulding-boxes from a conveyer to an emptying station and then to the moulding-machines, the boxes are moved along a track by the direct or indirect action of one or more automaticallyactuated devices distributed along the track and feeding the boxes. That part of the conveyer for the poured moulding boxes shown in Fig. 1 comprises two parallel portions. Poured boxes are removed from the longitudinal run shown at the right-hand side and pass along a track 21 through a discharging station and then on to another portion of the track at rightangles to the first and positioned above the other longitudinal run of the conveyer. From the end of the second track the boxes are lifted to moulding-machines disposed between the two runs of the conveyer as indicated at 3. As each moulding-box 2 on a plate 1 of the conveyer comes opposite the end of the track 21, it moves a roller 9 on a lever 10 depending from a shaft 8 carrying cams 11, 12, controlling the supply of compressed-air to a cylinder 4, so causing a depending arm 6 to push the box off the plate 1 and on to the track 21. In order to obtain a sufficiently long range of movement of the arm 6 it is coupled with the piston-rod 5 of the cylinder 4 by gearing comprising racks 27, 28, Fig. 4, engaging pinions 24, 26 in a housing 23 and coupled by a central gear 25. After the rod 5 has completed part of its stroke, the end 29 of rack 27 abuts a stop 30, whereupon the housing 23 travels along the rack 27 and causes the rack 28, carrying the arm 6, to move relatively to the housing. A similar action occurs on the return movement of the rod 5, which is initiated when a moving member contacts a stop 31 (not shown). The track 21 comprises side-plates 20 and rollers 22, the first six of which are carried by a frame 34 vibrated from a motor 35 to shake out the sand and castings on to an inclined grid beneath, which grid is also vibrated. The boxes are pushed along the track by the following boxes and when a box contacts roller 44, a pusher arm 47 coupled to the piston-rod of a second compressed-air cylinder 40 is actuated to move it at right angles along rollers 41 of the second limb of the track, at the end of which the boxes are removed to the moulding- machines by compressed air-driven lifting devices 49. If the rate of supply of moulding boxes to the second track exceeds the rate of removal to the moulding-machines, or if for any other reason the pusher arm 47 meets undue resistance, a roller 51 carried by the pusher is rocked to rotate a shaft 53 to operate a switch 58 which stops the drive of the conveyer and consequently of the transfer cylinders 4, 40.

Title: Improvements in electron discharge devices
IPC: H01J31/04
Filed: 1940-11-22
Abstract: 545,445. Electron discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 22, 1940, No. 16807. Convention date, Nov. 24, 1939. [Class 39 (i)] An electron discharge device of the beam type comprises a substantially straight cathode 14, a cylindrical electrode 16 surrounding it and having a slot 161 parallel to. it, means such as rods 17 for forming a beam adapted to pass through the slot, means such as rods 18 between the cathode and the slot for deflecting the beam, an output electrode 19, and a pair of shielding and deflecting electrodes 20 on opposite sides of the beam.between the slot and the output electrode. In the form shown, the cathode is of rectangular section and is coated on its front face 15, and the plates 20 are of arcuate form. The device may be used for measuring the angle of phase displacement between two electrical oscillations, for controlling circuits in dependence on this angle, for maintaining specified conditions governed by it, and it can also be used for frequency multiplication. For the first purpose, one of the alternating voltages is applied across the electrodes 18 and the other across the deflecting plates 20. The electrodes 18 deflect the beam to and fro across the slot 16<SP>1</SP> ,the beam passing intermittently through the slot only at such times as its deflection is substantially zero. The intermittent beam passing the slot is deflected by the plates 20. Should the alternating voltage applied to them be in phase with that applied to the electrodes 18 the deflecting field close to them will be zero at the moment the beam passes them, and it will be undeflected; should, however, there be a difference of phase the beam will be deflected proportionately to it. The electrode may be formed as a fluorescent screen to indicate this deflection. Fig. 6 shows a modification in which three electrodes 25, 26, 27 are employed, connected so that in in-phase conditions only the circuit 41 is energized, whilst under out of phase conditions a push-pull circuit 40 is energized. By connecting both the electrodes 25, 26 to the same side of the transformer two impulses are in the same direction and applied to it for each cycle of the applied voltage, resulting in frequency doubling. In another form, one output electrode is formed with one or more slots parallel to the slot 16<SP>1</SP>, behind each of which is a further electrode. A further form comprises an output electrode in the same cylindrical surface as the deflecting plates 20 and a second electrode outside it which covers the gaps between it and the plates 20.

Abstract: 1385505 Modulating light RESEARCH FRONTIERS Inc 12 April 1972 [12 April 1971] 16975/72 Heading H4F In a light modulator, particles suspended in a fluid are such that when they are aligned, e.g. by a magnetic and/or A.C. or D.C. electric field, the transmissivity in a direction parallel to the field direction is increased in one part of the electromagnetic spectrum and decreased in another part. At some particular wavelength the variation in transmissivity may be zero (the "crossing point"). As particularly described, the suspension could consist of TiO 2  or cobalt aluminate particles in iso-pentyl acetate and nitrocellulose; or of Fe 2 O 3 .H 2 O in toluene and a modified polyvinyl pyrrolidene. In each case the final ingredient stabilizes the suspension. A filter may be provided to block all of the light below or above the "crossing point" or to block selected portions of the spectrum. The modulator may be used in series with one or more similar modulators, either of the type described above, or of thetype where transmissivity is charged in the same sense over the entire spectrum. Alternatively a single cell comprising two or more different types of particle could be used for the same effect, e.g. TiO 2  and Fe 2 O 3 .H 2 O; or herapathite with TiO 2  or iron oxide. Such devices may be useful in photographic colour printing, e.g. for colour balance or for illuminated displays which change colour.
