Abstract: 699,090. Dynamo-electric machines. ADAMS ENGINEERING Inc., L. S. Aug. 31, 1950 (Aug. 31, 1949], No. 21525/50. Class 35. [Also in Group VIII] In a felting machine in which the material to be felted is introduced into the nip of a pair of rolls, at least one of which is subjected to vibrations of high frequency of the order of several thousands of complete vibrations per minute, the roll or drum 41 is given an axial vibration by a vibration generator 42, which is mounted on a bracket on the frame 10 of the machine, and comprises a box-like member 56 having a partition 57 on which is mounted an electromagnet 60, connected in an alternating current circuit. An adjustable armature 61 is mounted on an arm 62 which is resiliently mounted by leaf-springs 65 on the member 56. A further box frame 68 is resiliently mounted on the box 64 by means of leaf-spring 66, 67 and is connected by shaft 44 and coupling 45 to the shaft of the drum 41. The lengths of the springs supporting the box members 64, 68 are adjusted so that the latter vibrate in resonance. The material is introduced into the nip of the drum 41 and a roll 49, a belt 50, driven by a roll 46, holding the material in contact with the drum over an extended arc. The material may then be subjected to rotary vibrations between a feed-belt 20 and a drum 11 which is coupled to a vibratory motor 12, having an outboard bearing 13 on a bracket 14. The stator coils of the motor are supplied with direct current, and those of the rotor with alternating current, so that a rotary vibration is produced. A circular weight 34 is keyed to the shaft of the drum 11, and is set at such a position that it vibrates in resonance therewith. In a modification, the material is passed between pairs of pressure rolls, one roll of each pair being driven to forward the material, while the other is given an axial or rotary vibration by means similar to those described above, and the supporting belts are omitted.

Filed: 1946-07-18
Abstract: 618,888. Guides for typewriting. FLIND, H. C. July 18, 1946, No, 21567. [Class 100(iv)] [Also in Group XV] A guide sheet for use as or with a typing sheet has a guide mark at 45 degrees to the edge of the sheet and in line with and extending to or nearly to a lower corner, to indicate the distance of a line of type from the bottom of the sheet by reference to that of the mark from the edge of the sheet. Guide marks 11, 12, 13, 14 may extend from both lower or all the corners to form one or two isosceles triangles. The remaining area is filled with a rhombus 18- 21 or other symmetrical configuration, such as one formed by two lines from the vertical edges intersecting at the centre of the sheet. Adjacent areas may be contrastingly coloured or shaded, and the sheet may have such a design on either side. The marks may be applied to the uncoated side of a carbon sheet 22, which may be attached to the typing sheet along its upper edge, or as a watermark to the typing sheet. The guide sheet may be used to centralise a heading, or to indicate the starting point of a line of type finishing at a desired position. The triangles may be divided into smaller triangles dividing the horizontal edges of the sheet into two or three and defining the median vertical line of the sheet, whereby position indicating may be effected for two or three separate columns. Further triangles may be provided to divide the vertical edges into three or four parts and indicate the median horizontal line.

Title: Improved ore dressing
IPC: B03B5/36
Filed: 1936-08-06
Abstract: 478,895. Washing granular materials. FIFER, A. J. J. Aug. 6, 1936, Nos. 21685 and 23556. [Class 82 (ii)] To control the discharge of concentrates and/or middlings in a gravity separation process using an aqueous suspension of a heavy mineral such as galena or barytes as separating medium there is provided a valve or valves defining a container or containers interposed between the separating vessel and a discharge outlet and a separate supply of fresh medium for the container whereby the container or each container in succession can be filled with fresh medium and then by operating the valve or one of the valves communication between the separating vessel and such container can be established so that the concentrates or middlings pass into the container and can be discharged through the discharge outlet by further operation of the valve or one of the valves. By this means discharge is effected without disturbing the level of the medium in the separating vessel and without dilution of the medium. In the form shown in Fig. 1, the separating vessel 1, which is provided with an agitator with blades 11 and 12, has extensions 13, 13a for withdrawing concentrates and middlings respectively. Between these extensions and discharge outlets 16, 16a are valve housings 14, 14a in which work rotary valves 15, 15a each formed, as shown in Fig. 5, with vanes 18 so that each valve defines containers 19, 20. The valve housings 14, 14a are connected with valved pipes 21, 21a respectively through which fresh medium from a tank 22, which is supplied from the main medium supply pipe 3, can be admitted to the housings. The level of medium in the tank 22 is the same as that in the separating vessel 1. To admit the medium into the containers defined bv the valve, connecting pieces 30 with slots 31 which register with the medium supply pipes are provided between the vanes 18 of the valve. The housings are provided with air-vent pipes 27, 27a which terminate over the separating vessel 1 and which are adapted to be closed by float valves 29, 29a. In operation, fresh medium is admitted into one of the containers, e.g. the container 20, expelling air through the pipe 27 until the container is full and the float valve 29 is closed. The operation of the valve then brings the container into communication with the vessel 1 and the concentrates pass into the container and on further operation of the valve the concentrates and medium are discharged through the outlet 16. The middlings discharge functions in a similar way. In the form shown in Fig. 6, a container 32 to receive the concentrates is defined by slide valves 33, 34, the valve 33 being inclined to facilitate discharge of air through the airvent pipe 27. In the middlings discharge the valve 33a by which the middlings enter the container 32a is vertical.

Title: Improvements in or relating to the protection of steel from hydrogen damage
Inventor: BOUCHER BERNARD LE
IPC: C23F13/02
Filed: 1958-07-07
Abstract: 844,227. Preventing corrosion. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. July 7, 1958 [July 5, 1957], No. 21762/58. Class 123(1) Damage to steel structures immersed in an aqueous corrosive medium, particularly one containing H 2 S and/or HCN, by fissuring, blistering and embrittlement due to hydrogen absorption is prevented or reduced by first adjusting, if necessary, the pH of the medium to between 4 and 10, preferably to between 7 and 8, and then applying a cathodic current of a low, predetermined value to the structure. The value of the current is found by immersing a number -of samples of the structural steel in the same pH-corrected corrosive medium under the same corrosion conditions. The fragility as determined by a tensile strength test and/or the number of surface flaws per unit area found for each sample after unit time of application thereto of a particular cathodic current is plotted against the current density on the sample. The current applied to the structure is then set to give a current density thereon corresponding to that on the sample having the minimum fragility and/or number of surface flaws. The Figure shows the curve drawn for a number of steel samples immersed in water saturated with H 2 S and containing 2 mg. per litre of O 2 . The pH of the solution was adjusted to 6À5 with NaOH. The number of surface flaws per sq. dm., plotted as ordinates against the current densities reveal a current density range P 1 -P 2  in which the absence of flaws indicates that the hydrogen absorption is zero. The working current is accordingly set so that the structure current density falls within this range. The range may be widened by the addition of an organic inhibitor to the corrosive medium in the proportion of from 1 to 10 parts per million. Suitable inhibitors are aliphatic amines, quaternary ammonium salts, organic sulphides and disulphides, mercaptans and imidazolines.
