Title: Method and apparatus for producing single crystals of refractory material
IPC: C30B23/00
Filed: 1962-12-28
Abstract: 968,785. Crystallizing. CENTRE D'ETUDE DE L'ENERGIE NUCLEAIRE. Dec. 28, 1962 [Dec. 29, 1961], No. 48886/62. Heading B1G.

Title: Electro-luminescent display devices
IPC: H05B33/12
Filed: 1964-12-03
Abstract: A solid state image display system, operable in either a storage or a non-storage mode, includes a first layer 14 (Fig. 2, not shown) of electroluminescent material having associated crossed multiple electrode arrays 12 and 16 to which signals are applied for the excitation of a desired luminescent pattern; a layer 46 of photosensitive material which exhibits an impedance change which is both dependant upon the intensity of incident radiation, and which persists after the cessation of the latter; and a second layer 48 of electroluminescent material arranged electrically in series with layer 46, and with electrodes 40 and 42 for applying an alternating potential across the two layers, to provide a luminescent display in layer 48 persisting, after the cessation of the original signal, for as long as the impedance variation in layer 46 persists.  The frequency of the A.C. voltage applied to the conductor arrays 12 and 16, which is amplitude modulated by the signals to be displayed may be chosen to cause layer 14-of zinc sulphide activated with copper, lead, and chlorine-to luminesce with either green or blue light.  The photosensitive material 46 is chosen to be insensitive to green but sensitive to blue light, whereby choice of the frequency applied to the conductor arrays 12 and 16 permits operation in either the nonstorage mode-when the display is provided by the first electroluminescent layer 14- or the storage mode.  The frequency 52 applied across conductors 40 and 42 is such that the second electroluminescent layer 48 emits green light, whereby optical feedback to the photosensitive material 46 is prevented. A barium titanate layer 50 provides a screen for the luminescent display.

Abstract: 1,248,943. Casting moulds; flasks. W. C. LANE. 18 Oct., 1968 [26 Oct., 1967], No. 49633/68. Heading B3F. A mould has a feeder head comprising a fluid impervious shell 23 or 30 having an open bottom to permit entry of melt into a feeder head cavity 22 in the shell, a refractory inner lining 32 in at least a portion of the shell, a temperature responsive fluid pressure-producing agent contained by the refractory, and a chill seal 37 around the open bottom of the shell for sealing contact with the melt to provide a fluid impervious seal between the shell and the melt. The refractory lining 32 is preferably greensand and the water content of the greensand acts as a fluid pressure producing agent. The pressure producing agent may be powdered zinc or a salt flux with a high thermal expansion. A fluid conducting shaft extends from the lining into the feeder head and may either be a porous rod 38a or a tube 38. In operation, melt is poured into the mould cavity 18 and a layer of metal bounded by a dashed line 25 immediately freezes. The greensand liner 32 is heated to vaporize the water which migrates towards the shell 23, 30 and condenses along a front. As the heating is continued the condensation front migrates towards the shell 30 until the shell is reached, whereupon the water is revaporized and escapes as steam along the fluid conducting tube 38, 38a to apply pressure upon the melt in the feeder head. A vent 40 is provided in the feeder head, but the vent is sealed when the feeder head is full of metal by the metal freezing in the vent or by a manually or automatically operated valve (not shown). Flasks.-The feeder head shell 23 is bolted to the flask 10.
