Title: Forming mixing heaps of bulk material
IPC: B65G69/10
Filed: 1971-09-13
Abstract: 1368110 Controlling level in hoppers KONINKLIJKE NEDERLANDSCHE HOOGOVENS EN STAALFABRIEKEN NV 13 Sept 1971 [14 Sept 1970] 42632/71 Heading B8S [Also in Division G3] The speed of a digging machine supplying a dumping machine via a throughflow hopper 1 is controlled manually or automatically according to a measurement of the degree of filling of the hopper. The object of the invention is to provide a uniform supply of material, e.g. ore, which is composed of a mixture of various grades. This is achieved by dumping the material in a large number of horizontal layers and digging it away vertically, and the present invention is to ensure that each layer is of uniform thickness over its entire area, by providing a uniform flow of material to the dumper. The level of material in the hopper may be detected photo-electrically or by gamma radiation, but as shown its weight is measured by supporting devices 8, 9, a third support 10 being provided by a non-measuring ball joint. Outflow on to conveyer 13 supplying the dumper is controlled by two shaking troughs 15, 16 regulated by controlling the speed of motors 17. 19. The weighers are connected to an indicator in the cab of the initial digger (feeding the hopper), the indication being manually or automatically corrected for the specific gravity of the material. The digger driver adjusts his speed accordingly, or the corrected signal may effect the speed adjustment automatically. The difference between the two weight signals differentially adjusts the outflow control motors to ensure even distribution in the hopper, and their speed is also adjusted jointly by a signal from a further weigher 21 to keep constant the weight of material on conveyer 13. Provision is made for stopping the digger if the level exceeds an upper limit or stopping the outflow troughs at a lower limit until a separate higher limit is reached. This is to protect the troughs.

Title: Improvements in or relating to the cutting of thermoplastic materials
IPC: B26F3/06
Filed: 1964-10-20
Abstract: 1,048,378. Cutting thermoplastic materials. G. M. PFAFF A.G. Oct. 20, 1964 [Oct. 23, 1963], No. 42666/64. Heading B5A. In a method of cutting or severing thermoplastic material a cutting or severing tool is brought to a first temperature range within the plasticizing range of the material to contact and cut the material after which its temperature is raised to that of decomposition of the material to effect cleaning of the tool. As described, the or each tool which is of a metal or alloy of high electrical resistivity is connected in series with a variable resistor across the secondary winding of a transformer, the primary of which is connected via a switch to the supply terminals 1 and 2. After cutting, a switch is closed to energize a relay which is then held by closure of a holding switch to connect a tap point of the primary winding of transformer to the supply terminals so that the current to the tool is increased and its temperature rises to that of decomposition of the material. A time delay relay energized on closure of the holding switch determines the duration of the excess heating of the knife and thereafter a time delay relay is de-energized to restore the circuit to its initial condition.

Title: Apparatus for the production of helically toothed mechanical parts from sintered metals
IPC: B22F5/08
Filed: 1964-10-26
Abstract: 1,091,321. Pressing helical gears. ATELIERS R. LAURENT S.A. Oct. 26, 1964 [Dec. 18, 1963], No. 43596/64. Heading B5A. Helically toothed gears are pressed from metal powder, in a helically grooved die 17, by upper and lower rotatable rams 1, 21, each of which is provided with a helically toothed tip which intermeshes with the grooves of the die. Ram 1 is carried by a member 2, which is fixed to a helically toothed gear-wheel 3, itself fixed to a plate 4. This assembly is seated, by thrust bearings 4<1> in a cap 7, carried by the upper plate of the press, and a casing 6, which has interior helical teeth 11, and which is resiliently movable relative to a lower cap 5. Interposed between the casing 6 and gear-wheel 3 is an annular helically toothed gear-wheel 12 which has extensions 12<1> which are seated, by thrust bearings 13, 14, in cap 5. The die 17 is carried by a frame consisting of plate 16, rods 18 and cross-head 20, which frame is slidable, in sleeves 19 through fixed lower press platen 15. The lower ram is carried by a member 22 which is seated on platen 15 by a thrust bearing 23 and which carries a helically toothed gear-wheel 24. Wheel 24 co-operates with an annular helically toothed gear-wheel 28, which itself meshes with a casing 26, carried by platen 15, and which is seated by thrust bearings 31 on crosshead 20. In operation the die is first filled and the upper press plate then lowered to force cap 5 against plate 16, and to move casing 6 relative to said cap. This relative movement causes gearwheel 12 to rotate relative to casing 6 which in turn causes member 3 and thus ram 1 to rotate, the ram being driven down into the die. When casing 6 abuts cap 5, plate 16 and thus gearwheel 28 are forced downwards. The relative movement between gear-wheel 28, casing 26, and gear-wheel 24 causes wheel 24 to rotate thus rotating ram 21 and facilitating its further entry into the die as the die is forced downward. The powder is thus compressed between the two rams.

Abstract: 1,127,905. Processing nuclear energy spectra. LABEN LABORATORI ELETTRONICIE NUCLEARI S.R.L. Oct. 18, 1965 [Oct. 22, 1964], No. 44067/65. Heading G1A. A nuclear energy spectrum is transformed so as to have the same scale as another spectrum with which it is to be processed. The spectra are recorded in a ferrite core memory and the spectrum to be transformed is operated on digitally channel by channel in accordance with manually set operators which are chosen to bring the barycentres of corresponding energy peaks on the two spectra to the same channel. A linear shift of channels is used to eliminate a difference in the threshold energies of the spectra, a compression or expansion of one spectrum is used to eliminate differences in y and to eliminate different amplification effects both operations are used. The invention may be used in connection with activation analysis spectra, and passing reference is made to spectrum stripping to determine the amount of Cs 137 in a Cs 137/Co 60 mixture.

Abstract: 452,304. Electromagnetically - operated valves. JUNKERS & CO., GES., 39, Junkersstrasse, Dessau, Anhalt, Germany.- (Assignees of Bosch Akt.-Ges., R. ; 4, Militarstrasse, Stuttgart, Germany) March 8, 1935, No. 7320. Convention date, April 19, 1934. [Class 135] A safety ignition device for gas burners having an electromagnetically-operated valve actuated by a thermocouple has at least a part of the mass of the magnet movably arranged in relation to the gas valve when the valve is in its closed position. In one form, Fig. 1, a spring-lifted central core 12 is slidable in the electromagnet 10 and is formed at its lower end with a valve plate 14 normally co-operating with a seating 15 of non-magnetic material to close a gas passage 17, 18, 19 leading to an ignition burner 16. A thermocouple 22 connected by a wire 21 to the solenoid 11 of the magnet energizes the magnet when the burner 16 is lighted. When the core 12 is pressed downwardly, the burner 16 can be lighted and so, through the couple 22, cause the magnet to be energized and attract the main valve 9 which normally rests on its seat by gravity. When the core 12 is released, it lifts, under the action of the spring 13, and carries with it the main valve 9 which thus remains open while the burner 16 is alight. A passage 24 supplies gas to the burner 16 when the valve 9 is open and the valve 14 closed. In a modification, the core 12 is operated by a stem which passes freely through the main valve 9 and is connected to a push button. A valve controlling the gas supply to the burner 16 is mounted on the stem. The whole of the electromagnet may be movable instead of a part. Specification 452,315 is referred to.
