Title: Improvements in or relating to image dissector tubes for use in television systems
IPC: H01J31/44
Filed: 1936-03-02
Abstract: 471,199. Image dissectors &c. FARNSWORTH TELEVISION, Inc. March 2, 1936, No. 6253. Convention date, March 12, 1935. [Classes 39 (i) and 40 (v)] In dissectors with elemental areas of the electron stream from a photo-electric cathode 5, Fig. 2, passing through a scanning aperture 30, the electrons passing the aperture reach an electron multiplier M with opposed cathodes 21, 22 disposed in the path L of the light-rays from the picture to be transmitted to the cathode 5, and so shaped and arranged that the optical image at the cathode 5 is not affected by the presence of the multiplier M. The multiplier is in a narrow glass tube 9 supported as shown in Fig. 1, transversely across the cylindrical envelope 1 near a window 6 at the end opposite to the cathode 5. As described in Specification 471,492, accurate focusing of the electrons from the cathode 5 is produced by a magnetic field coil 41 and envelope coatings 18, 19 and by making the cathode 5 concave. The multiplier cathodes 21, 22 are small semi-cylinders separated by a gap 24 and with end plates as shown to reduce inertia due to caesium ions. A resonating coil 32 interconnects the cathodes, and their potentials are oscillated at very high frequency by an oscillator 49 with a single connection 39 to the cathodes, the apertured shield 13 opposite only one cathode 21 providing a capacity coupling to earth. The cathodes 21, 22 and the coil 32 may be of silver, and caesium may be introduced through a tube at 31. The output signal is taken at 57 from a central rod anode 11 which may be surrounded by a grid. Dimensional details are given and a discussion is included of the electron multiplication action and methods of periodically interrupting it to prevent saturation. As shown, the voltage supply to the oscillator 49 includes an oscillation from a lower-frequency source 51 to interrupt the action at this lower frequency. With cylindrical cathodes 21, 22, no magnetic field is necessary in the multiplier. The oscillator 49 may include a vacuum tube or electronmultiplying tube. The Specification as open to inspection under Sect. 91 comprises also opposed-plate multipliers of general application and signal detectors as described in Specification 471,399. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to processes of mineral oil distillation
IPC: C10G7/00
Filed: 1925-03-07
Abstract: 230,821. Sun Oil Co., (Assignees of Pew, A. E., and Thomas, H.). March 17, 1924, [Convention date]. Hydrocarbons, distilling; film evaporators.-In distilling mineral oils, for example topped crude oil to obtain lubricating oil, vaporization is effected by distributing the oil in thin films over the tubes of a heat-exchange apparatus heated by mercury vapours. The oil may be passed in succession over a series of heaters maintained at different temperatures by using mercury vapours at different pressures. The distillation may be effected under an absolute pressure of 1-25 mms. of mercury. Mercury vapours generated in a boiler w pass by pipes u w, into the headers d of heat-exchangers a, b and through the tubes c. The condensed mercury returns by pipes 10, 11 and a constant level tank y to the boiler u. Uncondensed vapours are withdrawn by a pump 16 to a condenser 13 containing a cooling coil. The pump 16 serves to maintain a lower pressure and therefore a lower temperature in the upper than in the lower heater. Oil, supplied by a pipe e and distributor f, passes in film form over the tubes c of the upper heater a and the unvaporized portion passes through a seal g and a distributor h, on to the tubes c of the lower heater. Vapours pass by pipes k, j to condensers m, n and collecting tanks o, p, which are maintained under reduced pressure by a pump r. Pumps s, t serve to withdraw condensates from the tanks o, p.

Abstract: 369,730. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hamm, C. L. ; 221, 1st Street, Pittsfield, Massachusetts, U.S.A.) Feb. 28, 1931. No. 6325. Convention date, Feb. 28, 1930. [Class 38 (iii).] A split phase induction motor employing capacity in the auxiliary phase has a main primary winding 11 with different terminals for connection to sources of supply of different voltages, and a starting winding 12 connected to the main winding in series with a capacity, the main winding serving as an adjustable autotransformer to vary the relative magnitudes of the voltages impressed on the main and starting windings. Speed control may be effected by connecting the mains to different tapping points on the winding 11. If the auxiliary winding circuit is to remain connected during normal running for power factor correction, the amount of capacity may be varied by employing two condensers connected in parallel at starting and in series during normal running. The necessary change may be effected automatically as shown in Fig. 3. A relay 23 having a coil 25 connected across the starting winding 12 through a resistance 26 is energized at sufficiently high speed to close the circuit of a coil 27 of a relay 24 to connect the condensers 20, 21 in series. In the event of an overload causing a drop in speed, the relays operate to re-connect the condensers in parallel. If close control is unnecessary, a single relay may be used.

Title: Improvements in and relating to the manufacture of artificial threads, filaments and the like
IPC: D01D10/04
Filed: 1935-03-01
Abstract: <PICT:0452924/IV/1> Artificial threads, filaments, and the like, are led into a centrifugal box so that the thread crosses itself at an angle of at least 12 DEG , and after the cakes have been formed and subjected to wet treatments, they are dried by mounting them one above another, without separating members, about a perforated tube spaced from the inner walls of the cakes, and introducing hot air or other gas into the hollow centres of the cakes.  A weighted plate or the like rests on the upper cake and presses the cakes together, descending as the cakes contract during the drying process so as to remain in contact with the upper cake.  The air is passed slowly and evenly through the cakes and moisture is gradually displaced from the inner layers of thread to and through the outer layers which are the last to lose moisture.  The process results in uniform, unstrained, threads.  The air may be at a temperature of 90--100 DEG  C. and at the beginning of the process at a pressure of 6--8 inches of water. The cakes may be deformed from annular shape before drying, but preferably after they are placed on the tube through which air is supplied.  As shown, hot air is passed from chest A to perforated pipe C over which cakes D are placed in colunn form, and through the cakes from inside to outside.  As the cakes contract, the flanged sleeve E and weight G descend and maintain contact between flange F and the upper cake. Specification 290,833, [Class 2 (ii)], is referred to.

Filed: 1953-03-12
Abstract: 737,417. Pulse modulation and generating circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 12, 1953 [March 12, 1952], No. 6871/53. Classes 40 (5) and 40 (6). In a detector of unmodulated or amplitudemodulated pulses with constant repetition frequency a delay line serves as an energy storage device, a low-pass filter being connected in series with the line. As described with reference to the detecting of unmodulated pulses, a battery U, Fig. 1, supplies energy over resistor R to a line FL of characteristic impedance R and electrical length equal to twice the pulse length. The key K is closed and then opened to terminate the pulse when the wave front, reflected at the far end, arrives back at the input. The line discharges completely between pulses through the low-pass filter F having a cut-off at half the pulse recurrence frequency. The line may take the form of a single inductor and the first capacitor of the filter, Fig. 3 (not shown), or a series circuit across the input to the filter, Fig. 4 (not shown). A pulse generator, Fig. 5, comprises a filter F, line FL and load R fed from a D.C. source E. By varying the source voltage at a low frequency, amplitudemodulated pulses are generated. In a pulse multiplex system, Fig. 6, a modulating signal applied at A over filter F1, line FL1 and key K1 produces amplitude-modulated pulses representing one channel which are fed over a common transmission line T to a remote point where a synchronously operated key K2 with line FL2 and filter F2 demodulates the pulses to give the modulation signal at B.

Title: Improvements in centrifugal separators
IPC: B04B1/00
Filed: 1925-03-14
Abstract: 258,204. Carter, B. C. March 14, 1925. Density separators.-In a centrifugal machine for separating solid particles from liquids or gases the bowl is provided with a concentric annular conduit 16 between an inner tube 15 and an outer perforate tube 1. The conduit 16 is open at its ends and as the fluid passes through, the heavy particles are thrown through the perforations in the tube 1 into the drum 2. A gland 7 on the inlet end of the drum engages the stationary boss 8 of the supply inlet which contains a cone 14 and vanes 13 decreasing in pitch as they approach the rotating tubes 1, 15. The tube 15 is also provided with radial vanes 17 and the outlet opening through the rotating boss 18 is flared and provided with vanes 19 which decrease in pitch as they recede from the drum. The rotary parts are enclosed in a stationary casing 12 and the form shown in Figs. 1 and 2 is intended for the purification of oil. The dirty oil is delivered under pressure to the stationary boss 8 and passes between the vanes 13 into the annular space 16. By imping- ing on the vanes 17 the oil rotates the drum. It is carried round by the vanes 17 and any solid particles are separated from the main stream of oil; they pass through the perforations in the tube 1, through the oil in the drum 2, and accumulate on the wall. The surface of the wall may be roughened and cooling fans may be provided. Short tubular projections may be arranged at each hole in the tube 1. The drum may contain a, nest of tubes with' concentric annular spaces arranged in series or in parallel. An outlet with a small relief valve may be provided near the axis, for the discharge of any air passing with the oil through the drum. A modification, shown in Figs. 6 and 7, is used for cleaning gases. The annular bowl is mounted on the spindle 26, supported in bearings 28, 27 in a housing 29 carried by vanes 30 in an outer housing 31. This may be applied, for example, to the air intake of an internal-combustion engine. The central part 15* of the bowl is of stream line formation and carries vanes 33 so that the indrawn air rotates the bowl. Radial vanes 34 within the bowl assist in the separation of the particles which pass through the perforate wall 1* into the casing 2*. Curved vanes at the outlet of the bowl tend to straighten the air stream. External vanes 36 may be used to assist in the rotation of the bowl when it is used in an exposed position, as for instance, on aircraft. In a modification the spindle is fixed in a housing and the bowl rotates on it. The wall 1* may have a series of annular partitions.
