Title: Improvements in or relating to magnetic compasses
IPC: G01C17/00
Filed: 1930-06-17
Abstract: 358,998. Earth inductor machines. MINORSKY, N., Moore School of Electrical Engineering, Philadelphia, U.S.A. June 17, 1930, No. 18524. Convention date, Sept. 5, 1929. Addition to 318,538, [Class 114, Ships &c., Propelling &c.]. [Class 35.] The steering system described in the parent Specification is modified to form a magnetic compass. A shaft 3, as shown in the Figure, preferably of nonmagnetic steel, driven by a motor 4, carries a cylinder 1 of insulating material having slots in which are wound coils 2, 2<1> connected in series to form a single coil. The cylinder 1 may have embedded in it laminations of high-permeability alloys such as permalloy in order to increase the flux due to the horizontal component of the earth's field. On the shaft 3 is also fixed a small rotor 5 made of discs of soft iron and having two windings 6, 61 arranged so that their planes are at an angle to one another. The rotating system is mounted in a casing 14, 15, which carries the compass card 21 and is itself rotatably mounted within an outer casing 23 suspended by gimbal rings 26, 27 and springs 28 from an external support 29. The coils 6, 6<1> rotate within the field of a permanent magnet 7 which is mounted on a threaded column 8 so that it may be raised or lowered, without rotation, by means of a handle 11 and bevel gearing 9, 12. The flux penetrating the rotor 5 may thus be varied. A magnetic screen 20 surrounds the motor 4 to prevent leakage flux from affecting the coils 2, 2<1>, 6, 61. The two coils 6, 6<1> may be replaced by a single coil, the two half-coils 2, 21 being inclined to one another instead of parallel.

Title: Method of and apparatus for dressing grinding wheels
IPC: B23P5/00
Filed: 1958-06-10
Abstract: 860,664. Trueing grinding wheels; diamond tools. SUPER-CUT Inc. June 10, 1958 [June 10, 1957], No. 18529/58. Classes 60 and 124. A method of trueing a grinding wheel '52 comprises presenting a selected point or edge 60 of the surface of a diamond dressing stone 14 to the wheel with its (110) crystal direction parallel to the direction of abrasion (i.e. with its direction of high resistance to abrasion perpendicular to the surface of the wheel), and effecting traversing movements between the stone and wheel. A flat a is thereby generated on the stone, and then first one edge of the flat is applied to the stone with the (110) crystal direction parallel to the direction of abrasion until a second flat b is generated which forms an edge with the first flat a, and then the second edge of the first flat is applied to the wheel again with the (110) crystal direction parallel to the direction of abrasion to generate a third flat c which also forms an edge with the first flat, the two edges thus forming a ridge in the plane of the first flat in the same positional relation to the diamond as the initial point. The stone 14 is mounted in a shank 12 which is pivotally adjustable about a bolt 32 to one of three positions determined by a bolt 46 in one of three holes 38, 40, 42 on a holder 22 mounted on a slide for traversing movements across the grinding wheel ; in the central position, the axis of the shank passes centrally through the stone and intersects the axis of the wheel. The stone may be an octahedron, tetrahexahedron, slab or other shaped diamond and is mounted so that the direction of the (110) dodecahedron plane is parallel to the direction of abrasion. After the initial point has worn to form the first flat a, the tool can be angularly adjusted by repositioning the bolt 46 to pivot the axis of the shank through between 6 to 30 degrees first on one side and then the other, the consecutive movements of the shank producing flats a to m on the stone. Angular movements of the axis of the shank may be effected by inserting the shank, the bolt 46 being used in the same hole. Satisfactory trueing may be attained providing the (110) direction of the diamond does not deviate more than 5 degrees from true parallelity with the direction of abrasion.

Abstract: 208,182. Smith, A. J. Q., (Sheremeteff, A. E., and Blacher, E. C., (trading as Sheremeteff & Co., A. E.)). July 8, 1922. Mechanically operated by vehicle.-Power for operating railway points and the like is provided by the operation of a member by the wheels of a passing train which transfers the power to a mechanical accumulator near the operated member from which it is transmitted to the device to be operated under control from a distant point. Fig. 2 shows a treadle a adjacent to the rails adapted, when depressed by trainwheels, to compress a spring b by means of rods d and to reciprocate a pawl c which, as the spring is released, rotates the ratchet wheel e. A chain passes round the wheel e, the wheel h and two pulleys by which loops k, l, are formed in the chain and which are attached to weights n, m. Rotation of the wheel e clockwise is prevented by a pawl g. When driven by the pawl c, the wheel e shortens the loop k and raises the weight n and lengthens the loop l which is kept taut by the small weight m. The weight n tends to rotate the disc h, which is connected to the parts to be operated by a crank i and rodding but this movement is prevented bv a stop s engaging the tooth r, which may be released by any suitable means, such as an electromagnet, to allow the disc h to rotate half a revolution at a time, such movement being controlled by a suitable brake device as the dash-pot Q. A spring p may be fitted in the transmission link work.

Abstract: 1,012,428. Indicating-apparatus. BOURNS Inc. May 6, 1964, No. 18844/64. Heading G1J. An adjustable instrument e.g. a potentiometer with a helical plural-turn resistance element comprises a cylindrical shell 14 rotatable through ten revolutions to effect adjustment of the instrument from end to end of its range and having a slot 14 s engaging the resilient end of a pointer 34 to drive it over indicia on a dial 20 a and so indicate fractions of a revolution while the pointer 34 drives a pointer 36<SP>1</SP> through gearing 39, 40, 40 b, 44 over the indicia to indicate complete revolutions, the arrangement being such as to prohibit concurrent positioning of both pointers 34, 36<SP>1</SP> at the index mark 0 representing the ends of the instrument range. The gear ratio may differ slightly from ten to one, then if the gearing is arranged so that the indication is exact for five revolutions the pointer 36<SP>1</SP> will be a little out of register with the other index marks when representing other whole numbers of revolutions and will be offset from zero on one side or the other at the two ends of the range and thus indicate to which end the shell 14 is set. If the gear ratio is made equal to ten to one then the ambiguity may be resolved by placing a stop in line with the zero index and making the pointer 36<SP>1</SP> flex or slip when it meets the stop.

Filed: 1937-07-10
Abstract: 498,523. Strainers. FLINT, J. A. July 10, 1937, No. 19208. [Class 46] Solids are separated from liquids in a container which has a sloping perforated bottom extending above the liquid level and is vibrated so that solids collecting on the bottom are conveyed upwardly thereon out of the liquid. The vibratory movements are such as to give the same average velocity in both directions of movement and may be of a frequency of 3000 cycles per minute. The apparatus is particularly applicable for dewatering coal. The container shown has sides 11, a bottom 12 perforated with oval apertures and a lower end wall 16. A sheet of fine gauze is riveted or otherwise firmly secured over the bottom 12. The container is vibrated in a direction at an acute angle to the bottom 12 by an electromagnetic vibrator 23 carried by a bracket 20, which is attached to the sides 11 and to spring bars 21, the ends of which are fixed to a casting 22. The casting 22 is supported by a pair of flexible members 28, comprising coil springs, and a similar pair of supports 29 are connected to the lower end of the container. The mixture of liquid and solids is fed to the lower end of the container through a pipe 40 and fills the container to the level 18. The vibration causes the solid matter collecting on the bottom to travel upward and pass over the upper end 19 from which it is delivered by a shoot 31 to a conveyer 32. Some liquid passes through the perforated bottom into a hopper 34 and other liquid flows over the wall 16 and is directed into the hopper by a flume 35. Matter settling in the hopper may be returned by a pump 39 through a pipe 139 to the centre of the container and liquid overflows from the hopper into a flume 36. The bottom 12 may be reinforced by transverse plates 33.
