Patent GB-294408-A (GB)
Title: X-ray system
Inventor: SMITH SELTZER FRANKLIN
IPC: H05G1/20
Filed: 1927-10-27
Abstract: 294,408. Smith, F. S. Oct. 27, 1927. R÷ntgen-ray apparatus.-Relates to a system employing an incandescent-cathode ray-tube, and consists in including in the high voltage circuit an electrric valve which is made conductive periodically to permit energization of the tube. The device enables a single X-ray beam, or periodic beams, of high intensity and short duration to be produced. The apparatus comprises supply mains 6 to which circuits 1-5 are connected. Circuit 1 includes a step-down transformer 10 for heating the filament of a rectifying valve 8. The middle point of the secondary of this transformer is connected to an earthed point 12. Circuit 2 includes a transformer 16 which heats the cathode filament 14 of the X-ray tube 15. Circuit 3 includes a transformer 22 for heating the filament of a Magnetron 20, the anode 41 of which is connected, through the mid-point of the secondary of transformer 16, to the cathode 14 of the ray-tube. Circuit 4 includes a transformer 24 which insulates the supply mains from the high tension of the ray tube. The secondary of this transformer is connected to a motor 26 which drives a generator 27 and a rotary switch 28. The generator supplies current to the magnetizing solenoid 29 of the Magnetron 20, and the switch periodically short-circuits a resistance 31 which is in series with the solenoid 29 and the generator. Circuit 5 includes a step-up transformer 34 with its secondary connected to the anode 37 of the rectifying valve 8 and to a condenser 36 through a. high resistance 38 and a low resistance 39. The other side of the condenser 36 is connected to the earthed point 12 and, through the secondary 11 of the transformer 10, to the cathode 7 of the rectifier. The junction point 40 of the resistances 38, 39 is connected to the cathode 19 of the Magnetron through the secondary 23 of the transformer 22. The anode 42 of the ray-tube is connected to the earthed point 12. In operation, so long as the arm 33 of the rotating switch 28 short-circuits the resistance 31, current flows through the solenoid 29 and the magnetizing field prevents current from flowing through the Magnetron. During this time, the condenser 36 is charged by the transformer 34. When the arm 33 moves off its sectors, the resistance 31 reduces the current through the solenoid 29 to such an extent that the condenser 36 can discharge through the Magnetron and therefore through the ray-tube 15. In a modification, the rotary switch 28 may be replaced by a handoperated make-and-break switch and single X- ray beams may be produced. The Magnetron may also be replaced by a three-electrode valve, the switch 28 in this case being arranged to change the potential applied to the grid of the valve, so as to make the path between the filament and the anode alternately conductive and non-conductive. The apparatus may be used for the treatment of articles for the destruction of insects with which such articles may be infested.

Filed: 1929-09-23
Abstract: 332,815. Demoulin, C. Sept. 23, 1929. Emulsions, making.-In the manufacture of fuel briquettes from wood charcoal, pitch derived from tar obtained by the distillation of wood is employed as a binder which is brought to an emulsion by the addition of a heated alkaline solution. To the pitch heated to a temperature of about 100‹ C. is added a solution of sodium carbonate at approximately the same temperature, and the emulsion is fed into a centrifugal disintegrator simultaneously with the powdered charcoal heated to about the same temperature. The resulting mass is warmed to a temperature of about 120‹ C. to break down the emulsion and is then pressed into briquettes. To aid the combustion of the finished briquette, a small quantity of sodium nitrate is incorporated in the mixture fed into the disintegrator.

Filed: 1929-09-24
Abstract: 337,142. Lemoine, P. L. Nov. 24, 1928, [Convention date]. Spray carburettors.-In order to ensure proper carburation at low speeds, the air inlet to the carburettor is fitted with a loaded valve 6 which remains closed at low speeds, and the space 9 in front of the valve is connected by a conduit 11 to a nozzle 12 which directs a current of air across the fuel jet 3; also the float chamber 2 is connected by a conduit 13 with the space 10 beyond the valve 6. The richness of the mixture at low speeds may be adjusted by means of an adjustable bye-pass 18, Fig. 2, connecting opposite sides of the valve 6, so as to vary the amount of air passing through the nozzle 12. In order to prevent loss of power at high speeds due to the action of the valve 6, the action of the spring 8 loading this valve is removed at high speeds by a piston 21 working in a cylinder 20 connected by a conduit 22 to the choke 14. According to the Specification as open to inspection under Sect. 91 (3) (a) an adjustment may be provided in the conduit 13, and also in an additional conduit connecting the float chamber to the engine side of the mixture throttle 5. The jet 3 may be arranged to be inactive when the throttle valve is closed, fuel for slow running being then supplied by an auxiliary jet. The nozzle 12 may be applied to carburettors having two fuel jets, in which case one jet 3 may be arranged, as shown in Fig. 7 (Cancelled), under an aperture 36 in the nozzle 12, which has an extension 28 for acting on the main jet 23 placed at the narrowest. portion of the choke. The jet 23 may aLso be arranged axially with the float chamber and may have an extension acting as a guide to the float. Where one of the fuel jets is placed high above the constant level, or where it is desired to increase the output of the jets at low speeds, the float chamber may be connected by a conduit leading to the side 9 of the valve 6 or to the atmosphere. In another form of carburettor, the nozzle 12 and choke tube, are vertical, with two fuel jets arranged one above the other. In a modification, of this vertical type, the nozzle 12 is constituted by an annular passage surrounding the fuel passage, which is formed with a terminal jet at its upper end. and with an intermediate jet. Other forms of horizontal fuel jets are described in which the air nozzle 12 surrounds the jet. This subject-matter does not appear in the Specification as accepted.

Bags or sachets are formed from two superposed flat foils, or sheathing, thermo-plastic film &c., and shaped so that when they are filled they open out to form a flat base on which they can stand, the bottom-edge welding line lying centrally across the flat base and is joined to the ends of one or both side edges by short lateral welds defining between them an obtuse angle. As shown in Figs. 4 and 6 a conical bag is made of two sheets 6 welded around the perimeter by two side walls welds 7, a long base weld 8, and on two other lines B<SP>1</SP> C<SP>1</SP> and C<SP>1</SP> A<SP>1</SP>. These lines form an obtuse angle so that when the bag is filled the point C<SP>1</SP> moves more into the centre of the bag and eventually a substantially flat bottom results. The base of the bag may be of any form of gradulateral or hexagonal and in volume may be conical pyramidal or cubical and may be formed with entry and pouring spouts. The bags may be sheathed partially by rigid or semi-rigid surfaces 96 Fig. 23 provided with folding scores 102 so that they conform to the opened out bag. The surfaces may have complementary tabs 99 for seaming under the bag, and have tabs 97 for engaging over a second strip (95 not shown), surrounding the bag and which is attached thereto by side wall welds 7. In a further-embodiment the bags may result in a hexagonal liquid container, Fig. 25 with side supports 108, and, a neck 114 which can be folded back into the bag beneath a strip 113 to form a sufficiently fluid tight closure. The flat sides may be cut from a web as shown in Fig. 22. The shut lateral welds defining the obtuse angle may be constituted so that the thickness of the weld is reduced near the fold, Figs. 9 and 10 (not shown).
