Title: Improvements relating to surface discharge spark plugs and methods of making parts thereof
Filed: 1952-01-07
Abstract: In order to prevent air gaps forming between the electrodes and separating member due to differences in the co-efficients of expansion in the sparking plug described in Group XXVII, the member is made of an elastic mass of asbestos, glass fibres, heat resistant fibrous materials or other insulating material, such as mica.  The impregnating agents which can be molten substances or colloidal or true solutions may be applied to the separating member before, during or after its assembly into the sparking plug.  The separating member may be impregnated under pressure, or in some instances vacuum, with:-(i) chromic acid (ii) chromic acid and lead nitrate (iii) boric acid (iv) sodium acetate (v) a mixture of methyl and dimethyl silicon trichloride (vi) a silicon compound varnish (vii) lead nitrate (viii) lead nitrate and hydrochloric acid (ix) silver nitrate (x) sodium acetate and hydrochloric acid (xi) silver nitrate and hydrochloric acid (xii) silver and lead nitrates with hydrochloric acid (xiii) sodium ammonium phosphate.  Where powdered mica is used for the separating member it may be impregnated with either a mixture of methyl and dimethyl silicon trichloride or a silicon compound varnish.  The material may be heated at varying temperatures during and after impregnation depending upon the substances used. Specifications 631,386 and 645,403, [both in Group XXVII], are referred to.

Title: Improvements in or relating to induction compasses
IPC: G01C17/30
Filed: 1942-01-13
Abstract: 554,275. Magnetic compasses ; repeater compasses. AGA-BALTIC AKTIEBOLAG., (formerly AGA-BALTIC RADIO AKTIEBOLAG.). Jan. 13, 1942, No. 516. Convention date, Jan. 13, 1941. [Class 37] An induction compass comprises an iron armature 12 rotatable about an axis 13 in the gap between iron poles 10, 11 in which is fixed a coil 14, in which is generated a voltage proportional to the longitudinal direction of 10, 11 in relation to the magnetic field. The Specification shows by mathematical analysis, that the flux through the cores is given by the polar diagram 15, Fig. 7, in which the incompleteness of the two circles, due to the rotation of 12 in the field itself when the cores lie along the E-W axis fails to provide a sharply-defined zero point of voltage at that position of the cores. Accordingly a polarizing flux is superimposed in accordance with curve 16 and is equal to the maximum flux of the earth's field, thus producing a resultant cardioid curve 17 with a well-defined zero point in the direction S. The superimposed flux may be that of a permanent or electromagnet. Fig. 8 shows a repeater compass in which the arrangement of Fig. 2 is duplicated by providing two pairs of cores 18, 19 and 20, 21, two coils 30, 31, and two armatures 22, 23 driven by a motor 25, the polarizing fluxes being set up by oppositely-polarized electromagnets 26, 27 in series with a variable resistance 22. This arrangement yields two cardioids which are mirror images of one another about the E-W axis. One end of each coil 30, 31 is connected to the respective cathode of a diode valve 40, 41, the anodes of which are connected by resistors 44, 45 between which a connection is taken to the other ends of both coils 30, 31. Depending on the inclination of the cores 18 ... 21 with the field, one or other of the coils 30, 31 will generate a higher e.m.f. which will produce a larger voltage-drop across the associated resistor 44 or 45. The corresponding triode valve 46 or 47 will pass a larger current to the corresponding one of the opposing field windings 38, 39 so driving the motor 37, pinion 35, toothed non- magnetic case 33, and cores 18 ... 21 until no voltage-difference exists, corresponding to the E-W axis. The device may be gyro-controlled to prevent influence by rolling of the vessel.

Title: Improvements in and relating to the coating of metal and other surfaces
IPC: C23C4/06
Filed: 1936-01-08
Abstract: Metallic or non-metallic surfaces, e.g. wood or plaster surfaces, are coated by spraying thereon a mixture comprising powdered glass or other similar siliceous material, such as quartz and some sands and clays, and one or more metals in powdered form. The metal and siliceous material may be mixed in any proportions and the spraying is effected by passing the mixed powder by means of compressed air or gas or by suction through or into a stream adjacent to an oxy-acetylene or other high temperature flame which is played upon but does not appreciably heat the surface to be coated.  The spraying-pistol described in Specification 432,831 may be used.  The coating produced has a matt surface which may be ground or polished to give a smooth reflective surface.  The use of powdered aluminium, copper, zinc, and lead is referred to.  The process may be used for producing corrosion-resisting coatings on articles such as ships' hulls, acid or other tanks in chemical industries, machinery &c., and in general for protecting iron, steel, magnesium, aluminium, and their alloys from corrosion or heat.  It may also be used for ornamental purposes in which case a pigment or pigments may be added to the material before it is sprayed.  Thin flexible foils may be made by spraying the material on to a surface prepared to prevent adhesion, and moulds or templets may be made by spraying on to a former, adding a backing material if necessary for increased strength, and removing the coating from the former.  Specification 18716/10, [Class 82 (ii)], also is referred to.

Filed: 1938-01-11
Abstract: 494,472. Rotary cutters. ETZKORN, R. Jan. 11, 1938, Nos. 953 and 954. Convention dates, Jan. 11, 1937 and Feb. 4, 1937. [Class 145 (i)] Rotary cutters for smeary substances are provided with means movable relatively to the cutting knife edge to remove the chips after each cutting action. The cutters may be reciprocated in the holder by eccentric mechanism so that thus cutting edges move against clearing edges held against movement in the holder or the cutters may be fixed in the holder and the clearing means reciprocated. In the form shown in Fig. 6, two cutters are slidable radially in the holder 2 which rotates about the lower centre 5, the cutters being operated by means rotated about the upper centre 8 so that their cutting edges follow the dotted circle. The cutting edges thus move against sharp edges in the holder whereby chips are removed after each cut. In a modification the means for removing the chips is a separate part disposed between the cutters and the holder, the two cutters being integral. When the cutters 1 are fixed in the holder, as shown in Fig. 7, cleaning elements 22 are reciprocated over their cutting edges by eccentric or similar mechanism as the holder rotates. In a modification, the cleaning elements may be oscillated about a centre. The clearing elements may be of hard material to keep the cutting edges sharp. The edges of the knives may be indented.

Title: Detecting system of push of earth button
Inventor: KATSURA YOSHIHIKO
IPC: H04Q1/38
Filed: 1983-01-04
Abstract: PURPOSE:To detect stably the push of an earth button by means of a subscriber circuit which holds tthe current value at a fixed level at the side of the line A and regardless of the length of the line, by switching the voltage monitor to the current monitor at the side of the line B for the push of the earth button. CONSTITUTION:The current is converted into the voltage by a microresistance 204 and an operational amplifier 205, and this voltage is compared with the reference value 206 by a comparator 207. At the same time, photocouplers 208 and 209 are provided. The output of the 209 is set at L level while a current is flowing toward a line A. The output of the 207 is set at L level when the current of a line B is less than the value 206, and the output 211 is set at H level. Thus it is considered that an earth button is pushed. Therefore the push of the earh button is discriminated if the current flowing to the line B is set at <=1/2 current value of the line A since the resistance value is generally equal between resistances 106 and 107 when the line has a long length.

IPC: G11B5/84
Filed: 1993-01-05
Abstract: PURPOSE:To build the magnetic recording medium having a high recording density and large capacity by realizing the substrate for the magnetic recording medium which is small in surface sag of the outer peripheral part of the reference position and substrate deformation. CONSTITUTION:A chamfer part 10 formed at the outer peripheral edge of the substrate 11 for a magnetic disk is formed to a shape of 0.125mm length and 27.5 deg. angle, by which the surface sag of the outer peripheral part is improved and the deformation at the end face of the substrate is minimized. As a result, the traveling characteristic of the magnetic head in the outer peripheral part is improved and the lower floating of the magnetic head is realized even in the outer peripheral part of the substrate 11. The magnetic disk medium having the high recording density and the large capacity is thus built.
