Title: Improvements in or relating to the testing of solid material for determining specific radiation absorption capacity and apparatus therefor
IPC: G01N23/16
Filed: 1954-08-27
Abstract: 762,432. Automatic control systems for coal cleaning. STAMICARBON N. V. Aug. 27, 1954 [Aug. 28, 1953], No. 25005/54. Class 38 (4). [Also in Groups XX and XL (b)] In a method of determining the specific radiation absorption capacity of finely-divided material such as pulverized coal or of controlling the ash content of the coal for example during the coal cleaning process a sample is spread out as a layer and then moved relatively to the irradiating beam at constant velocity during which time the mergent beam is compared with a reference beam and the reference beam attenuated to bring the beams to a predetermined relationship and the adjusting movements of the attenuator are summed to give a single specific absorption capacity value for the entire sample. As shown (Figs. 2A, 2B), pulverized coal dust to be tested for ash content is fed from a hopper 6 by an electromagnetic vibrator system 7 into a groove 5 near the periphery of a disc 1 which rotates at uniform velocity. Arms 28, 29 rotate with the disc and each time contact 31 is closed by arm 29 a sample is allowed to fill the groove. X-rays from a source 13 are divided into two beams and pass, one through the groove containing the best material and the other through the edge of a circular optical wedge 11 to a detector 23 comprising a fluorescent screen 24 and a photocathode 25. A rectangular disc (see below) oscillates so as to obscure each aperture in turn so that the photo-sensitive device is alternately responsive to both beams. A servomotor 12 responsive to'the difference in the two outputs adjusts the optical wedge 11 to make both beams equal and at the same time adjusts a variable condenser 27 which is A.C. fed. The successive values of the condenser are integrated and indicated on a meter 39. After examination the sample is removed-from the groove by a brush and section device 9. Contacts 30 are closed by arm 28 to reset the integrator before the next sample is introduced. Disc 1 may be replaced by an endless grooved band. The output of the integrating device may be used to control a coal cleaning process so as to maintain the ash content of the output constant. Zero adjustment.-A gauge plate 32 is attached to the disc 7 to enable the sensitivity of the apparatus to be adjusted in dependence on the desired average value of the sample. Contact 31 resets the integrator before this control measurement is made. The beam interrupting device comprises a rectangular plate 17 of radiation-absorbing material suspended on two slack conductor strips 18, 19 by strip 20. Strips 18, 19 are positioned between the poles of permanent magnets 21, 22 are connected together at one side and to an A.C. source at the other. Magnets 21, 22 are so positioned that the direction of the two fields are opposite. Plate 17 oscillates in a plane perpendicular to the direction of propogation of the X-rays interrupting the two beams alternately. Specification 750,650 is referred to.

Title: Improvements relating to balancing machines
IPC: G01M1/04
Filed: 1923-10-08
Abstract: 205,486. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of S÷derberg, C. R.). Oct. 11, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Testing balance of rotary apparatus.-In a balancing machine the body to be tested, for example the armature of an electric motor, is rotatably mounted on a bed which is yieldingly supported and may oscillate vertically about a movable fulcrum. The bearings 25 for the armature 27 being tested are carried by a bed 4 which is mounted on the rollers 17 of a member 15. This fulcrum member 15 may be moved longitudinally by a screw 19 and hand wheel 20. The bed 4 has knife edges 5 engaging the rollers 17 and the fulcrum 15 slides in V-grooves in the frame 2. Springs 6 support the bed yieldingly at equal distances from its centre of gravity, and flexible strips 8 restrain its movement excepting in a vertical direction. On the part 16 of the fulcrum 15 is mounted an indicator 38 the pointer of which is actuated by a lever 40 pivoted on a knife edge 41. The lever engages at 43 with the bed plate 4. The means for rotating the armature comprises a pair of field coils 28 with laminated cores, and brushes 33 contacting with the commutator 36 and carried by arms 31. The method of use of the apparatus is as follows: The plane of static unbalance of the test body is first determined and marked, and the body is then mounted in the bearing blocks 25. Provision being made for the addition of correction weights in the planes A, A. and B, B, the fulcrum 15 is moved into the plane B, B, and the speed of the rotor is adjusted to synchronize with the natural period of vibration of the bed 4. The amplitude of vibration indicated on the dial 38 is a measure, of the correcting mass to be applied in the plane A, A. The mass to be applied in the plane B, B is determined in a similar manner by testing with the fulcrum 15 in the plane A, A. The angle with reference to the plane of static unbalance at which the balancing weights must be located is ascertained by calculation from the readings obtained on the dial as explained above, and the minimum reading obtained on the dial when the fulcrum 15 is moved along the rotor 27.

Abstract: 518,429. Filtering - media. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN. Aug. 25, 1938, No. 25024. Convention date, Aug. 25, 1937. [Class 46] [Also in Groups VIII and III] A fibrous product, for use as a filter, having a base of artificial silicate fibres, e.g., glass, is obtained by coating the fibres with an organic bonding agent and converting the bonding agent into substantially pure carbon by heating the coated fibre mass in the absence of oxygen. Specified bonding agents include carbohydrates, starches, oils, waxes and resins. Coating of the fibre may be effected by spraying, soaking or mechanical mixing. Carbonization may be effected in a closed chamber, or as a continuous process with exclusion of oxygen, at a temperature of 300-350‹C. The carbonizing temperature may be lowered by addition of small quantities of lime or alum. Oxalic acid, boric acid, chrome alum, tannic acid, lead acetate, copper acetate and urea give tougher bonds with starch. For filter diaphragms the porosity may be regulated by addition of a small quantity of inert material, e.g., clay or bentonite. The Specification as open to inspection under Sect. 91 describes also the use as bonding agents of aqueous dispersions of phenol-formaldehyde resins, powdered soft coal and metallic wax such as calcium stearate. This subject matter does not appear in the Specification as accepted.

Aug. 12, 1957 [Aug. 10, 1956; Dec. 11, 1956; July 24, 1957], No. 25436/57. Class 80(2). [Also in Group XXXIV] An electromagnetically-engaged friction clutch which may be used as a brake comprises an energizing coil on one side of a pack of clutch discs, a ring- shaped armature surrounding the discs and being connected by tension elements, e.g. tie bolts, to a pressure plate on the opposite side of the pack from the coil. In one form, an armature ring 66, Fig. 1, is connected to a pressure-plate 67 by tie bolts 68, the effective length of which can be adjusted by nuts 70 to compensate for wear in a pack of clutch discs 75. L-shaped legs 80 fast on a magnetic casing 50 carried by a driving-shaft 1 engage at their ends in notches 69 in the pressure-plate 67. A coil 49 in a casing 53 of insulating material is carried by the magnetic casing 50 which is formed with a flux-directing radial flange 77, and is enclosed by a pole ring 51. A collecting-ring 60, insulated from the main body of the clutch, is connected to the coil 49. To obtain the maximum possible area for the pack of clutch discs, the tie bolts 68 and the axial portions 83 of the legs 80 are arranged at the same radial distance from the main clutch axis. The gaps between the axial portions 83 of the legs 80 allow the free passage of cooling air. In a modification, the coil 49, Fig. 4, is mounted in a stationary housing 107 of magnetic material. A magnetic casing part 100, 77, a non-magnetic ring 114 and a pole-ring 105 rotate with the driving-shaft and are journalled within the stationary housing 107 by a plain bearing 112. The armature comprises a ring 102 of magnetic material connected, as before, by tie bolts 68 to a pressure-plate 67. As a modification, the plain bearing 112 can be replaced by a ball-bearing, Fig. 5 (not shown). The connection between the tie-bolts 68 and the pressure-plate 67 may include disc springs, Fig. 6 (not shown), surrounding each tie bolt so that the armature ring can move relatively to the pressure plate.
