Title: Improvements in the production of continuous strips of glass and apparatus therefor
IPC: C03B13/04
Filed: 1923-11-19
Abstract: 229,383. Pilkington Bros., Ltd., and Le Mare, E. B. Nov. 19, 1923. Rolling. - Relates to apparatus for forming a continuous strip of glass in which the molten glass issuing from a tank forms a pool on a travelling table and is carried by it beneath a roller, the pool being unconfined on the edges away from the roller. According to the invention, the back part of the pool is confined but the side edges are unconfined. In the construction shown in Fig. 1, the molten glass flows from the tank through a conduit 2 and forms' a pool 3 on a travelling table 4 which, with the roller 5, forms the rolling apparatus. The lower edge of the conduit is brought close to the table and confines the pool in a backward direction, and thus prevents it from spreading otherwise than forwardly and laterally. The side walls may be extended to form wings 8, Fig. 3, to protect the extending portions of the pool from cooling, and to prevent any backward flow of the upper portions which might form folds in the glass and consequent defects in the strip. The conduit 2 may be arranged at a distance above the table, the backward extension of the pool being prevented by a wall located beneath the mouth of the conduit and the table. The device may be used in connection with apparatus in which the table 4 is replaced by a roller on which the pool is formed.

Patent GB-465042-A (GB)
Title: Improvements in the manufacture and production of sulphates and sulphur
IPC: C01B17/96
Filed: 1935-10-24
Abstract: Ammonium or other sulphates and sulphur are obtained by bringing acid solutions of the corresponding sulphites or mixtures thereof with thiosulphates and/or thionates, alone or together with other salts or acids, into intimate contact with liquid sulphur, while supplying heat until the formation of thiosulphates commences, then stopping the supply of heat and the means for providing an intimate contact and using the heat of reaction evolved in this stage of the process for effecting the formation of sulphates and sulphur.  The supply of heat may be continued until the solution attains a temperature of 80--90 DEG  C. The heating and effecting of intimate contact may be produced by the direct introduction of steam.  The reaction may be effected continuously, the sulphite solution being preheated to 80--100 DEG  C. and pressed together with liquid sulphur through a wing-pump. The ammonium sulphite may be recovered by evaporation or by precipitation with concentrated sulphuric acid.  In the latter case the remaining sulphuric acid containing ammonium sulphite is returned to the process.  According to one example a solution containing ammonium sulphite and bisulphite is preheated to 90 DEG C. and is passed through a vessel in which liquid sulphur is kept in motion by means of a pump.  The liquid then passes to a container in which the conversion proceeds to completion, and is withdrawn in an amount corresponding to the liquid introduced. The sulphur settling in the lower part of the container is in part returned to the circulation pump while the remainder is periodically or continuously withdrawn.

Title: Improvements in or relating to geophysical prospecting
IPC: G01V1/00
Filed: 1965-07-12
Abstract: 1,112,651. Seismic surveying. GENERAL DYNAMICS CORPORATION. 12 July, 1965 [13 July, 1964], No. 29444/65. Heading H4D. Seismic waves are applied to the earth at spaced points and after reflection from substrata are simultaneously detected at a receiving station, the detected waves are utilized to produce waveforms at particular times as wavelets characteristic of reflections from respective strata, and the application of seismic waves to respective ones of the spaced points are delayed to maximize the wavelet characteristic of a selected stratum. An array of receivers may be employed, the time differences at successive ones being measured to give the angle # between the received wave and the normal to the earth's surface, since where v = wave velocity, #T R  = time difference between wave arrival at adjacent receivers and #R is the spacing between adjacent receivers. It is assumed that the transmitting array is short compared with the depth of stratum of interest, the apparent dip # of which is given by where #T S  being the time difference between actuation of adjacent transmitters and AS is their spacing. Time difference #T R  is measured by delaying individual receiver outputs: when the sum of the delayed outputs is a maximum, the delay imposed is #T R . Velocity v can be calculated from the expression where x is the mean distance between transmitting and receiving arrays and t is the mean time between transmitter energization and wave reception. The number of transmitting points is preferably about eleven with a spacing of 50 to 100 ft. True dip is determined by making a further measurement with the transmitting array turned through 90 degrees, or a twodimensional array may be employed. The sources are as described in Specification 1,010,788 or Specification 1,112,653. Wave trains of limited duration and on different frequencies are preferred. Recording apparatus for each receiver includes a bank of filters each connected to an individual magnetic recorder, summed play-backs from which are recorded. Each filter includes a narrow-band active circuit having adjustable frequency and Q- factor controls and operational amplifiers. A filter in which Q-factor increases automatically with frequency is described, reference being made to an article " Active Filter Element," Review of Scientific Instruments, April 1961; this filter is said to be particularly useful when utilizing pulse trains of equal duration. The summed recorder outputs are illustrated: pulse compression ensues. " Ground roll " noise is reduced. A linear distribution of transmitted frequencies is preferred; in one example the frequencies are spaced 11 c/s. and run from 35 c/s. to 90 c/s. Greater relative wave attenuation at the higher frequencies may be taken into account by adjusting source output or recorder channel amplification or by " multiple shooting " on the higher frequencies.

[Also in Group XXVI] An aircraft, comprising fuselage 1 and wings 2 housing gas turbine engines 3 for forward propulsion is provided with a plurality of fans 8 which rotate about normally vertical axes to provide vertical thrust to facilitate landing and take-off. Each fan is driven by compressed air supplied through a conduit 13 tapped from a supply pipe 12 connected to the compressor sections of the gas-turbine engines 3. The engines may be mounted in the fuselage or in nacelles external of the wing structure. The wing upper and lower surfaces in way of the fans are provided with span-wise extending slots, the upper slot being provided with pivoted slots which extend chordwise, the lower slot having slots which extend spanwise, the slots being moved into edge-to-edge alignment to complete the wing surface when the direct-lift fans are not operating. In a further embodiment Figs. 6 and 7 (not shown), an aircraft is powered for forward flight by turbo-prop gas turbine engines, one in each wing and each driving an auxiliary axial flow compressor through a clutch and transmission. Each compressor draws air through an intake opening on the top surface of the respective wing and discharges into a manifold common to both compressors, said manifold being connected to a plurality of branch pipes each supplying a fan 8, It is stated that the groups of fans in the two wings may be operated differentially to create a rolling movement on the aircraft which may supplement or replace the aileron control. Each row of fans discharges downwardly in front of a trailing edge, flap 9 which may be deflected to a position in which it directs the fan efflux forwardly for braking purposes. The thin jet sheet ejected by the fans through the lower wing slot acts as a " jet flap " to modify the aerodynamic pressure distribution over the wing to produce a considerable increase in lift. Specification 834,800 is referred to. Reference has been directed by the Comptroller to Specification 744,107.
