Patent GB-498724-A (GB)
Title: Improvements in and relating to electric insulation
IPC: C04B33/13
Filed: 1938-03-04
Abstract: Fused magnesium oxide having a moisture-resistant electrically insulating coating is obtained by mixing a preponderant proportion of the magnesium oxide with a minor proportion of an inorganic material, and heating the mixture to a temperature at which the magnesia reacts with the inorganic material to form a fused coating of the desired kind.  The heating must not result in the fusion of the magnesia, and is effected for such a period of time that, on cooling and comminuting the resultant mass, the individual particles of fused magnesia are protectively coated with a stable reaction product.  If necessary the firing is repeated.  Suitable additions to form the coating are silica, e.g. diatomaceous earth, silicates such as hydrous aluminium silicate, e.g. kaolin, or hydrous magnesium silicate, e.g. talc, if desired with oxide of calcium, magnesium, beryllium, aluminium, or zirconium.  The product may be used in the manufacture of electric heaters, or for other insulating purposes, if desired, in admixture with waxes, pitches, resins, varnishes, mica, asbestos, lead borate or other materials.  Specifications 144,767, [Class 37], and 413,905 are referred to.

Title: Machine for forging axially symmetrical workpieces
IPC: B21J9/18
Filed: 1952-03-18
Abstract: 720,492. Forging-machines. SAXER, A. March 18, 1952 [March 21, 1951], No. 6949/52. Classes 83 (3) and 83 (4). A machine for forging axially symmetrical workpieces comprises hammer tools 13 distributed round the periphery of the work, the tools being adjustable radially of the work by means 15 independent of the work-feeding means, and indicating means 49 to register the axial and radial movements. The forging box is mounted below the floor and has three hammers 13 reciprocated by eccentrics 2 driven by a motor 4. The eccentrics may be adjusted simultaneously by rotating the eccen. tric mountings 15 by a separate motor 19. Overloading of the machine is prevented by a disc coupling 6, the pressure on the discs being continuously varied by a cam 22, lever 23 and disc 26. The work is delivered horizontally to a gripping head 47, the jaws of which are closed by a pneumatic piston 48. The head is then rotated by a motor 37 until the work is vertical and a pneumatically-operated locking pin 43 is engaged. The work is rotated by a separate motor, not shown, and the head 29 is raised and lowered, by a motor 32, on columns 27, 28 protected by telescopic covers. The travel of the head 29 is communicated by a chain 51 and a sprocket 50 to a longitudinally movable pointer 69 in an indicating device 49. Adjustment of the diameter of the hammers is also communicated to the device through a crank 52 and a transversely movable bar 63 on which the pointer 69 is slidably mounted. The pointer thus moves in a manner similar to the shape of the work. By mounting a drawing of the work above or below the pointer the motors 19, 32 can be adjusted continuously to forge the required profile. The dimensions of the work are indicated by a spiral scale on a drum 70 showing the travel of the head, and a rotary drum 71 showing the diameter of the work. A five-position lever 83 controls the reversing and stopping of both motors. If conical shapes are to be produced, one motion may proceed continuously. Triangular or polygonal work is produced by stopping the rotation of the work. More than three hammers may be provided. The movement of the pointer 69 may be associated with an optical projection device. Chucks.-The jaws of the work-gripping head 47, Fig. 1, are operated by a pneumatic piston 48 acting through the linkage shown. Reference has been directed by the Comptroller to Specifications 650,550 and 650,633.

Abstract: 1382417 Pulse dividers GOULDER MIKRON Ltd 3 March 1972 [16 March 1971]  7041/71 Headings G4D D7X D6Y D6C1 D6C2 and D1D14 An input pulse train x is divided by a non- integral number A.BCDE using a modulus A updown counter a the output pulses from which are processed to feedback a pulse train a<SP>11</SP> in dependence on the non-integral part BCDE. In Fig. 1 the counter output is supplied to cascaded decade counters c-f having associated gates g-j each arranged to supply B, C, D, E pules respectively for each cycle of the associated counter, the values B-E being variable. A circuit K separates simultaneously occurring pulses from the gates and may also be arranged so that feedback pulses do not coincide with input pulses. In another embodiment, the feedback pulses are produced by overflow of an accumulator to which BCDE is added for each output pulse from counter a. Division by numbers such as ABCD.EF and O.ABCD is also possible, the frequency of the input pulses being multiplied by an appropriate power of 10 if required. Fig. 3 shows an arrangement for testing a gear mounted for rotation with an optical scale p. A probe riding over the gear teeth is coupled to a linear optical scale q to produce pulses q 1 which are divided by a non-integral number at a, b to bring pulses p<SP>1</SP>, q<SP>1</SP> into theoretical one to one relationship; and a phase detector S produces a signal for recording as an error trace t. In Fig. 4 (not shown) rotation of an input member is converted to a pulse train which is divided by a selectable non-integral number and the resulting count is converted to an analogue signal controlling a servomotor thereby providing a transmission system with variable reduction ratio.
