Title: Method and apparatus for bending and tempering glass sheets
IPC: C03B27/044
Filed: 1962-01-24
Abstract: <PICT:0968233/C1/1> In bending and tempering glass sheets in which the sheet is heated to soften and sag into conformity with a bending mould and then tempered by rapidly reducing the temperature, the opposite surfaces are reduced at different rates of cooling to cause at least one edge of the sheet to move away from and out of contact with the shaping surface.  Pressure of air blasts may be different on opposite surfaces to give different rates of cooling. Alternatively, the side rails 28, 29 and end rails 30 of the bending mould may be of substantial depth and this is stated to restrict the flow of air from blowers 13 past the lower surface. The side rails 30 and end rail 29 are notched at 32 while the end rail 28 is inclined upwardly at 33 so that the corner only of the sheet 10 contacts the rail.  The sheet 10 is shown in the tempered position, raised for rail 28, in dot-dash lines.  Specification 968,234 is referred to.

Title: Process for the preparation of lactams
Filed: 1957-01-28
Abstract: Butyrolactams and d -valerolactams, respectively, are formed by reacting substituted or unsubstituted g -aminobutyronitrile or d -aminovaleronitrile with water in the absence of a catalyst at a temperature of from 150 DEG  to 180 DEG  C.  The reaction is advantageously effected under pressure and in the presence of excess water, preferably in the presence of more than two mols. of water per mol. of nitrile.  Aqueous mixtures such as a solution of ammonia in water may be used instead of pure water.  The process may be continuous or intermittent.  In examples, d  - aminovaleronitrile, with varying amounts of water, is heated over a period of 1 1/4 hours to 180 DEG  C. in a shaker-type autoclave of V4A steel and maintained at this temperature for 4 hours, to produce d -valerolactam.  In a further example, aqueous ammonia is used instead of water. Specification 560,040, [Group IV], is referred to.

Patent GB-192095-A (GB)
Title: Improvements in and relating to electric rectifiers
IPC: H02M7/06
Filed: 1921-10-25
Abstract: 192,095. Freedman, P. Oct. 25, 1921. Arc lamps; vacuum tubes.-In a rectifier, a glass or silica bulb contains one or more cathodes of fused tungsten and one or more anodes, preferably of the same material, arranged so that the cathodes are maintained at white heat and the anodes at about red heat so as to emit positive ions which bombard the cathodes. The bulb may be filled with nitrogen, argon, helium, or neon, or a mixture, at a pressure between 1/6 and “ of an atmosphere. Each cathode may consist of a sphere or spheroid mounted on a stem adapted to minimize loss of heat. The anodes may be spheres, plates, or 'blocks, and are considerably larger than the cathodes. Starting is effected either by a high-pressure discharge cr by means of a filament heated by resistance and serving as a temporary electrode. This filament is situated so as not to be damaged by the main arc. When a high-pressure discharge is employed, the cathode 3, Fig. 1, and anode 2., or one of the anodes if the rectifier is a full-wave or polyphase one, are first connected by a double switch 4, 5 to. a step-up transformer winding 6, and subsequently are .connected directly to the mains or to a single-phase or three-phase transformer. In the second method of starting, a filament 13, Fig, 2, is supplied with heating current by a winding 14 of a transformer. Another secondary winding of the transformer is connected to the cathode 3 and through an electromagnetic switch contact 21 to the circuit of the filament. Initially, the cathode 3 acts as a temporary anode towards the filament 13. As soon as the cathode 3 is hot enough to allow alternating current to pass to the filament, the increased current opens the electromagnetic switch 21 and breaks the circuits between both windings and the filament, the main anode 2 then coming into operation. In a modification for full-wave rectification, there are two additional electromagnetic switches in the circuit leading from the first switch to one anode. One of these additional switches serves to close circuit to the second anode, and the other additional switch, when both anodes are operating, substitutes the direct current load for a resistance which is inserted in the cathode circuit to take the temporary reverse current at starting. In a three-phase modification, the load is allowed to receive this temporarily reversed current, and the two additional switches merely serve to place the second and third anodes in circuit. Instead of several anodes and one cathode, there may be one anode and several cathodes, shielded from each other by the anode. Specifications 152,694 and 157,041 are referred to.
