Patent GB-1061395-A (GB)
Title: Improvements in method and apparatus for applying coatings onto articles of manufacture
IPC: B05C19/00
Filed: 1964-06-17
Abstract: Powdered coating material is projected simultaneously towards opposite ends of slots or passageways in a heated article which is rotated at a given speed relative to the powder projecting devices in order to coat the walls and edges of the slots or passageways and the end faces of the article.  A preheated stator core (10), (Fig. 5, not shown), having windings slots (13a, 13b) is mounted on a rotatable holder (20) and is rotated thereon around the axis (R) so that the ends of the slots (13a, 13b) pass in turn between pairs of powder projecting nozzles (A, B and C, D).  The nozzles (A, B and C, D) are disposed substantially opposite to each other though they may be slightly offset, the oppositely directed impinging streams of powder causing turbulence in the slots which aids the formation of a uniform thickness of coating material. Each nozzle includes an injector (18) supplied with air under pressure through a line (80) while powder material is supplied e.g. from a fluidised bed via line (83) to the nozzle.  Each nozzle is pivotally mounted and thereby movable to a position which allows for the removal of the coated core.  For this purpose also the holder 20 is provided with a deformable outer surface such that when the holder is connected to a source of compressed air the outer surface is expanded sufficiently to grip the bore of the stator core.  When the holder is disconnected from the pressure source the surface becomes deflated and the core may be removed.  The surface parts of the holder (20) which make contact with the stator core serve to mask these portions from the coating materials.  The rotational speed of the core is such as to give a linear velocity relative to the nozzles in the range 0.5 to 3.0 inches/second.  Reference is made to the use of thermosetting epoxy resins and to a synthetic polyester resin which requires post-curing to harden the coated material.  The apparatus may be mounted within a closed casing having suction means for extracting surplus powder material (Fig. 1 not shown).

Title: Improvements in or relating to resistors
IPC: H01C7/00
Filed: 1965-06-16
Abstract: A composition for use in making fused resistors includes 30-100 wt. per cent finely divided indium oxide of crystallite size 200-2000 A. The composition may include a borosilicate glass frit, e.g. barium aluminium borosilicate, and/or a dopant, e.g. Sb, As, P, W, Si, Ta, Zr, Ti, Sn, Ce, Nb, Mo, Cu, Au, Pb, Ag, Pt, Pd, Li, or Nh4Cl.  The indium oxide and dopant are dry-mixed and pre-fired, and then the glass frit is admixed; or the indium oxide, dopant, and glass may be dry-mixed in one step. The mixed powders are now mixed with the liquid vehicle, which may include a resinous binder, a solvent for the binder, and a surfactant.  The resultant paste is applied in an appropriate pattern to a ceramic dielectric substrate, e.g. by silk screen. The substrate may already bear an electrode or conductive element pattern, or the electrodes may be printed over the resistor pattern.  The resistors are then fired in air or inert atmosphere, e.g. N2 and/or Hl, at 800-1200 DEG  C.  A glaze layer, preferably of borosilicate glass, may be applied as a paste of frit before the resistor is fired, or afterwards, in which case a second firing is necessary.  The indium oxide may be made by (a) heating In in O2; (b) dissolving In in HNO3, adding NH4OH or NaOH to produce indium hydroxide in solution, heating to produce indium oxide plus water and subjecting to a controlled heating cycle to grow crystallites in the desired size range; or (c) dissolving In in HNO3, heating the product to produce indium oxide and NO2, and subjecting the indium oxide to a controlled heating cycle.

Abstract: 1,152,413. Apparatus for providing parity checks. TELETYPE CORP. 9 June, 1966 [6 July, 1965], No. 25705/66. Heading G4A. Apparatus for generating a parity check signal comprises means producing a signal indicative of odd or even " 1's " in a word, second means for providing an output signal indicative of odd or even " 1's " in a predetermined number of words each of which may contribute not more than one of the " 1's " to the second count, and third means responsive to the two signals to produce a parity check signal if the two signals differ. As shown, an eight-bit word is applied to a set of EXCLUSIVE OR gates 31a-31d, 32a, 32b, 33 which provide an output if an odd number of " 1's " exist in the word. The output of gate 33 is applied to an EXCLUSIVE OR gate 34. The eight bits are also applied to AND gates 30a-30h respectively enabled by an ADD CHARACTER pulse. " 1's " at the appropriate gate act to change the state of a bi-stable element 38a-38h which thus serve to add modulo 2 the bits supplied thereto. After the summation a shift pulse is applied to line 35 and the data in each bi-stable element is shifted one place to the right causing the parity bits stored in each bi-stable element to be carried by spiral addition, i.e. adding bit 1 of word 1 and bit 2 of word 2 and bit 3 of word 3 &c. The time sequence is such that the data word is first applied to EXCLUSIVE OR gates 31-33 to provide a vertical parity check bit. This is applied to gate 34 and compared with the check bit of the previous eight characters. A parity bit is then transmitted to be added to a character or compared with a received parity bit. The SHIFT pulse is then applied and then the ADD CHARACTER. The cycle of operation is then repeated for the next word.

Class 136(1) A caliper brake for cycles is provided on the lower end of each lever 22 with an adjustable anchorage device which includes a slotted plate 10 and a flexible loop 12 for embracing the adjacent fork blade 28. The slotted plate 10 is connected to the caliper lever 22 by means of the stud 24 which adjustably secures the brake block 25 in a slot 23 in the lever 22. To prevent rotation of the plate 10, a tongue 27 is pressed out of the plate and enters the slot 23. The plate 10 is provided with an eye 15 through which the flexible member 12 may pass and which will receive and retain an abutment nipple 14 secured to one end of the member 12. The other end of the member 12 passes through a hole 16 in a screw clamp pin 17 which is passed through a receiving hole 18 in the plate 10. A washer 19 and nut 20 engage the screwthreaded end of the pin 17 to clamp the flexible member 12 between the head 21 of the screw and the plate 10. In a modification shown in Figs. 5 and 6, the plate 10 is formed with spaced eyes 31 to receive an externally screw-threaded sleeve 30. The flexible member 12 is passed through the sleeve 30 and an abutment nipple 14 is secured to each of its ends. The position of the sleeve 30 in the eyes 31 may be axially adjusted by means of a knurled nut 32 which is placed between the eyes 31 prior to the insertion of the sleeve 30. A further eye 33 is formed on the other side of the plate 10. A gap 34 is left between the tongue and the plate so that the flexible member may be passed laterally into the eye 33 and then drawn back to engage the nipple 14 in the eye.
