Title: Method of producing a roll of thermoplastic web
IPC: B32B27/00
Filed: 1961-07-18
Abstract: Thermoplastic web or film is heated at 90 DEG -140 DEG F. for at least 20 hours and then wound into a roll under tension at 80 DEG -140 DEG F. The process is particularly applicable to coated tapes, having a basis of, for example, cellulose acetate, cellulose acetate butyrate, polyethylene, nylon or polyethylene terephthalate.  Such a tape, after the initial heating step, to relax the film may be wound directly at 80 DEG -140 DEG F. on to a wide central core, or may be subdivided during winding into a plurality of narrow tapes.  The tape may also be subsequently divided and rewound.  The reels of tape so obtained are form-retaining and are not subject to wrinkling, loosening or deformation when subsequently subjected to ambient temperatures of, e.g. 50 DEG -140 DEG F.  In an example, a typewriter tape intermediate, comprising a film of cellulose acetate butyrate coated with a dispersion of segment in petroleum wax, is heated at 100 DEG F. for 24 hours.  The relaxed tape is wound and subdivided into small rolls at a tension of 150 grams per lineal inch width and at 90 DEG F.  Conventional coating, winding and heating apparatus are used.  Following the initial heating step, the relaxed tape may be stored indefinitely before the winding (conversion) step.

Title: Improvements in the production of aluminium nitride by electrically generated heat
IPC: C01B21/072
Filed: 1919-10-27
Abstract: 146,919. Armour Fertilizer Works, Assignees of Shoeld, M.). July 10, 1919, [Convention date]. Aluminium nitride is prepared by passing down through an electric furnace up which a stream of nitrogen or nitrogen-containing gas flows, a mixture of briquettes composed of alumina, carbon, and a binder, and larger lumps of carbon or other electrically-conducting chemically-inert material which serve as heating-resistances to convey the current through the mass and prevent fusing of the briquettes, local overheating, &c. The mixture of briquettes 20 and lumps 21 is charged continuously into the furnace 10 by hoppers 13 and passes down between the electrodes 15, 16, while nitrogen is introduced by pipes 22, 23. The entering gas is heated by passage through the treated material, and the hot spent gas preheats the entering material; a portion of the spent gas is discharged by pipe 27. while the remainder passes through a scrubber 28, where it is purified and cooled, is then mixed with fresh gas from pipe 31, and re-enters the furnace by pipes 30, 22, 23. The mixture of treated briquettes and carbon lumps discharged from the furnace is screened to separate the two components, and the carbon lumps are returned to the furnace for re-use.

Title: Improvements in carrier wave signalling systems
IPC: H04B1/40
Filed: 1932-09-22
Abstract: 407,404. Wired wireless systems; valve circuits. STANDARD TELEPHONES & CABLES, Ltd., RALPH, F., and TERRY, V. J., Connaught House, Aldwych, London. Sept. 22, 1932, No. 26366. [Class 40 (v).] A two-directional carrier wave signalling system, shown applied to a line circuit, includes a thermionic valve circuit having continuous oscillations circulating therein and acting alternately and impartially as a modulator and a demodulator for outgoing and incoming signals respectively. The circuit comprises two valves acting in push-pull as modulators, and in parallel as demodulators, the carrierfrequency oscillations circulating in parallel in the circuit of the valves, which may be back coupled to produce them. The carrier wave and one side band are suppressed from the line. Incoming low-frequency signals are applied in push-pull to the grids of valves 3, 4 from the line 1 and combined hybrid coil and input transformer 2. A combined hybrid coil and output transformer 6 passes the signals to the outgoing line 19 as a modulation of a carrier frequency produced by the back coupling 5 arranged in the common plate and common grid circuits of the valves 3, 4. The carrier frequency is eliminated from the line 19 by the push-pull output connection and one of the side bands by the filter 17. Incoming high-frequency signals on the line 19 are applied across the impedance 26 in the common grid circuit from the transformer 9, the valves acting in parallel as demodulators by reason of the circulating carrier frequency oscillations. The demodulated currents pass from the output transformer 7 connected in the common plate circuit, through a low pass filter 8 to the line 1. The valves may alternatively be arranged to act in push-pull for demodulation and in parallel for modulation. In a modification (Fig. 2, not shown) one side band is used for transmission in one direction and the other in the other direction, the line 19 being branched off through two separate band filters. A voicefrequency circuit may be added to the line 19 through the low pass filter 20. Grid bias for the valves is provided by the condenser and resistance 15, 16 and to minimise grid current modulation the resistance and condenser 22, 23 are connected between the grids. The H.T. blocking condenser 14 provides a high impedance to low frequencies in the common anode circuit and stabilizes the frequency of the oscillations generated. The transformer 7 is arranged to present a low impedance to the oscillation frequency by a suitable termination on the filter 8, and may also be tuned to the mean side band frequency by a condenser 27. The transformers 9 and line 1 may have circuits 10, 11 and 24, 25 respectively, resonant to the carrier frequency, connected across them to bye-pass carrier frequency oscillations. The self-oscillating circuit may be replaced by supplying a carrier from a separate master oscillator.

Abstract: 801,532. Tempering glass sheets. PITTSBURGH PLATE GLASS CO. Aug. 30, 1956 [Sept. 13, 1955], No. 26510/56. Class 56. In apparatus for tempering curved glass sheets as described in Specification 771,036 some at least of the tempering-fluid outlet nozzles 74 have flexible extensions 78 preferably of a silicone although rubber or thin copper tubes may also be used. The nozzle extension should be spaced not more than three and a half inches from the glass surface to be tempered and may be as little as a quarter of an inch from said surface since impact between the nozzle extensions and the rigid frame C supporting the glass-carrying mould M during their relative orbital movement merely causes the nozzle extensions to flex. The extensions 78 should be of the same internal diameter as the nozzle 74 which may have its outer surface feathered to receive the tube. Various forms of extension are described, namely a rubber or silicone tube reinforced by a metal spring, a metal tube connected to the nozzle 74 by a flexible rubber or silicone coupling or a tightly wound steel spring, or a tube formed itself of a lightly wound spring.
