Title: Improvements in or relating to filling machines
IPC: B65B1/46
Filed: 1940-09-06
Abstract: 605,855. Automatic control systems for container-filling machines. RAYMER, M. M. Sept. '6, 1940, No. 13962. Convention date, March 6. [Class 38 (iv)] [Also in Groups XVII and XL (b)] Weight.-A container-filling machine comprises a measuring device for delivering a measured load of fluent material into a container such as a carton, and means for moving the container to receive a measured load therein, on to a scale adapted to control a mechanism including a photo-tube and a lamp, for increasing or decreasing the measured load thereafter delivered by the measuring device in the event of the filled container varying from a predetermined weight. The cartons are transferred in pairs from a conveyer belt 35, Fig. 1, to a filling position beneath two spouts 16 by cam-operated pushers 44, 64, the leading carton then resting on a moving belt 29, but being temporarily prevented from moving forward preferably by means of a stop hook 65 constructed and operated as in Specification 605,857, [Group XVII]. When a carton comes to rest on the scale pan'37 and has received its charge, a pair of cam-operated clamping bolts 125, Fig. 16, releases the scale beam 91, and the carton is weighed. If the scale is unbalanced, an apertured plate 100 carried by the scale beam moves from a mid-position and permits light from one or other of two lamps 102 to pass to a corresponding photo-electric cell 105 to decrease or increase as described below, the quantity of material delivered to the next pair of cartons presented beneath the feed spouts. The material is fed to the cartons by two fourbladed'paddle wheels as described in Specification 605,856, [Group XVII]. For adjusting (under the control of the scale beam) the quantity of material delivered by the paddle wheels at each quadrantal movement, each paddle wheel 134, Fig. 19, is provided with an axially adjustable end 161 moved in one direction or the other to vary the enclosed volume, by a screw 163 operated through one or other of two clutch mechanisms. The clutch mechanisms are coupled up under the control of latching devices and electromagnets arranged in the photo-electric circuits of the scale beam. Mercury switches rocked by the extreme movements of the adjustable ends 161 of the paddle wheels are provided to prevent excessive movement of these ends in either direction, and a further mercury switch starts up a carton-shaking mechanism 253, Fig. 1, whenever the adjustable ends are moved to increase the feed. The shaking is for the purpose of settling the increased volume in the carton preparatory to a carton-closing operation. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specifications 605,856, 605,857 and 605,858, [all in Group XVII]. This subject-matter does not appear in the Specification as accepted.

Filed: 1946-09-02
Abstract: 613,411. Electric resonators. SPERRY GYROSCOPE CO., Inc. Sept. 2, 1943, No. 14382. Convention date, June 18, 1942. [Class 40 (viii)] [Also in Group XL (a)] In a reflex oscillator either the entrance grid or the exit grid is eliminated and the cathode or the reflector respectively forms part of the resonator wall for high-frequency current while being insulated from it for direct current; to prevent leakage of high-frequency energy past the gap thus left, a low-pass filter is provided formed of sections of transmission lines of alternately high and low characteristic impedance. In one form, the reflector 18, Fig. 1, arranged in an aperture in wall 11 of the resonator and flush with it, forms the end face of a high-impedance element 19 of the filter 19-22 comprising quarter-wave (or odd multiples thereof) sections of alternately large and small diameter within a uniform outer cylinder 17. Tuning is effected by screws 16. In another form, the high-impedance element 58, Fig. 5, forms the whole of one wall of the resonator 55, either with or without a central re-entrant portion 54. Tuning is effected by heating the terminal low-impedance element, which is in the form of a thin-walled tube 65, by an internal heater 62. This causes the tube to expand and move the reflector toward the entrance grid 10. In Fig. 7, the cathode 81 is disposed in an aperture in the resonator wall 98 and is backed by a low-pass filter 90 ... 97 in which it is the outer conductors which vary in diameter. The reflector 108 is behind the exit grid 102 and tuning is effected by screwing conducting or insulating plunger À 113 into or out of the field of the resonator. Specifications 535,767 and 612,404 are referred to.

Title: Improved manufacture of phosphorus
IPC: C01B25/02
Filed: 1932-05-24
Abstract: In the blast-furnace production of phosphorus, the amount of carbon employed in the formation of the briquettes is less than that theoretically necessary to reduce the phosphorus compound in the mineral treated, the limits being 15 to 75 per cent, preferably 25 to 75, of the theoretical amount.  In an example, a ground phosphatic rock containing 25,03 per cent of P2O5 and 33,65 of CaO is briquetted with coal, preferably bituminous, and sulphite liquor in the proportions 92,25 per cent of rock, 6 of coal and 1,75 of sulphite liquor. After drying, the composition of the briquettes is P2O5--24,29 per cent, SiO2--21,62, CaO--32,41, C--3,71, the proportion of carbon being 36 per cent of that theoretically necessary.  Siliceous material is added if necessary to bring the proportion of SiO2 to CaO to between 0,6 to 1 and 1,2 to 1. Normally, the porportions of the charge are 100 parts of briquettes, 4 of added silica and 70,3 of coke, a hearth temperature of 1600 DEG C. being maintained thereby.

Title: Improvements in or relating to joints for high tension electric cables
IPC: H02G15/24
Filed: 1926-06-12
Abstract: 255,033. Pirelli & Co. July 11, 1925, [Convention date]. Cable couplings.-Relates to means for connecting adjoining sections of high-tension cable of the type having a lead sheath 16 over paper &c. 9 surrounding a stranded conductor enclosing a hollow core filled with thin oil. A flexible connection 11 joins the conducting blocks 10 into a central socket 8 off which the bared ends of the cable sections fit, a strengthening tube 12 of insulation fitting into an outer concentric socket in each part 10. In this way oil cannot pass from one section to another. The straight joint, shown in Fig. 1, or a joint between two inclined sections, has tape 16<a> carefully wound round it and is enclosed in a brass casing 14 narrowed at the ends and connected to a thimble 15 joined by a wiped joint to the sheath 16. The Specification as open to inspection under Sect. 91 (3) (a) comprises also details illustrated in Figs. 3 (Cancelled) and 4 which show the upper and lower parts respectively of one side of a joint between two sections at an angle to one another. In this case the thimble 15 is secured to the sheathing 16 and to the sleeve 23 by wiped joints, but after the sheath has been stripped off a cylinder 25 of paper with bevelled ends is slipped over the insulation 9 and the bevelled ends are surrounded as shown by a metal cylinder 26 to prevent longitudinal electrical stresses. To ensure good contact between the cable and the end-piece 10, the bared end, Fig. 4 (Can.- celled), is inserted in a central socket as before and there is soldered to it a sleeve 33 having upper and lower flanges 34, 35 and adapted to be connected to and pass outwardly a series of bars 36, which when insertion is first made have a tolerance within the socket, but pressure on the cable releases the top ends from the rim 40 of a cage 40, 41. 42 and causes the lower rim 41 to engage recesses 43 in the bars, thus allowing the springs 38 to press them radially outwards. To maintain the lower strands in position and allow free passage of oil and easy withdrawal, they are soldered on to a sleeve 32 which also engages a distending core 30 in the shape of a coiled spring. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for continuous casting of metals
IPC: B22D11/117
Filed: 1972-03-29
Abstract: 1386154 Continuous casting INSTITUTE PO METALOZNANIE I TECHNOLOGIA NA METALITE 29 March 1972 [7 April 1971] 14881/72 Heading B3F A metal-gas alloy is formed and continuously cast as a rod, tube, wire or strip, by subjecting molten metal in a heated crucible 3 to the gas (to be dissolved in it) in admixture with a second gas which does not interact or dissolve in the metal, and then casting the alloy in a mould 18 whilst subject to an atmosphere in which there is a pressure of the first gas higher than the partial pressure of the gas in the mixture, to ensure that the dissolved gas remains in solution in the solidifying alloy. The gas mixture is passed from a reservoir 7 by way of a regulating valve 5 through a pipe 4 to saturate the metal which is covered by a flux layer in crucible 3 in a chamber 1. By opening a valve 9 briefly, the pressure beneath a cover 6 is raised to discharge metal through a conduit 12<SP>1</SP> into the mould 18 above which is maintained a pressure of the first (alloying) gas by way of a conduit 17<SP>1</SP> from a reservoir 14. Alternatively, the metal rises through a conduit 12, opening a non-return valve 11, to pass into a chamber 10 beneath a flux layer and beneath an alloying- gas layer supplied from the reservoir 14. Gas valves 16, 17 control the metal flow rate to the mould 18 from which the casting 19 is forced by gas pressure through a gas seal 22 at a rate controlled by a device 20. Devices, not shown, regulate the metal levels, temperatures and gas pressures as well as the alloy composition. A valve 21 on the container valve 6 releases gas pressure after discharge of a portion of metal from the chamber 1.
