IPC: D05B55/02
Filed: 1964-01-13
Abstract: 981, 271. Sewing machines. MEFINA S. A. Jan. 13,1964 [Jan. 26, 1963; Nov. 26, 1963], No. 1382/64. Heading D1G. A sewing machine needle holder, fixed to a needle bar, carries a screw adapted to force a needle-securing member against the shank of a needle received in a groove provided longitudinally in the central part of the needle bar, the needle  holder also being formed with an inwardly-directed groove, the lower end of which opens into the needle bar-receiving bore, and a member fixed in the groove having at its lower end at least one lateral projection adapted to guide the needle thread into the groove. A needle holder 1, secured by a screw 4 to a tubular needle bar 2, carries a screw 17 adapted to force a member 16 against a needle shank 10 received in a longitudinal groove 9 formed in a block 8 secured within the bore 3 of the needle bar by a transverse pin against which shank 10 abuts. Shank 10 carries two needles 11. Holder 1 is formed with an external, longitudinal, inwardly-directed groove 23, the lower end of which enters bore 3. A plate member 25, fixed in groove by rivetedover portions 26, is formed at its lower end with a pair of lateral projections 27 loosely received within notches 28 formed in the lower edge of holder 1. The respective edges of member 25 are formed with notches 29 at the inner ends of the projections 27. A thread 34 or 34a may be drawn over a respective projection 27 to enter the groove 23 by the associated notch 29. The lower edge of member 25 positions the thread adjacent the needle. In a modification member 25 is made from wire.

Patent GB-272799-A (GB)
Title: An optical pyrometer
IPC: G01J5/52
Filed: 1927-01-18
Abstract: 272,799. Hase, R. Jan. 18, 1927. Photometric apparatus.-An optical pyrometer which can also be used as a photometer comprises a telescope in which the heated or luminous body is seen simultaneously with a small surface illuminated by the diffused light of an electric lamp carrying a constant current, the luminosity of the comparison surface being varied as by the rotation of a disc of graded opacity inserted between the source of light and the surface, until the surface " disappears " when seen against the heated body. Fig. 1 shows diagrammatically one form of the optical parts, the heated body being observed through a telescope comprising an objective A and eyepiece B. The comparison surface G is mounted on a parallel glass plate J and is illuminated by a lamp D and reflecting-prism H, a diffusing-screen E being provided if necessary. The luminosity of the surface G can be adjusted by the rotation of an annulus F the opacity of which is graded circumferentially but is constant along any given radius. The surface G is preferably in the form of a cross having one arm parallel to a radius of the disc F and the other at right-angles thereto, so that when the radial arm disappears against the heated body, the other arm appears partly brighter and partly darker than the said body. A coloured glass screen C is provided for insertion when desired in the path of the light. Other forms of optical system are described, for example the light from the heated body may undergo successive internal reflections within a prism, the surface G being one of the reflecting surfaces, or the light may pass through a square prism divided diagonally, the surface G being on the diagonal surface. Figs 9 and 12 show on constructional form of the instrument, in which the whole apparatus is mounted in a cylindrical casing M. The object glass A is mounted in a slidable tube A<1> and the light is directed into the eyepiece B by a reflector consisting of two Porro prisms K<9>, K<10> at right-angles to one another, the comparison surface, not shown, being in the mirror surface of the prism on the axis of the eyepiece. The prisms are carried by a block T having bores T<1>, T' through which the light passes, and a bore T<3>, Fig 12, receiving a casing D<1> containing the lamp. The current for the lamp is supplied by a battery O and is controlled by a rheostat P, this current being measured by a meter R having a pointer R<1> and a scale R<2> visible through a window S in the casing M. The annulus F is in this form inserted in the path of the light from the heated body and is carried by a revoluble ring F<2> the rim of which is marked with temperature graduations which are also visible through the window S. A coloured glass screen C is mounted on a pivoted frame C<1> so that it can be inserted in the path of the light if required. The instrument may also be used as a photometer by causing light from the source to be tested to fall at right-angles on a white surface placed in front of the object glass A at an angle, for example 45‹, to the axis of the telescope.

Title: Heavy-metal oxide resistors and process of making same
IPC: H01C7/04
Filed: 1951-01-19
Abstract: 689,520. Metal oxide resistors; temperaturevariable resistors. STEATITE RESEARCH CORPORATION. Jan. 19, 1951 [June 7, 1950], No. 1523/51. Class 37. A method of making heavy metal oxide resistors, consisting essentially of compounds of the approximate formula MO.M<SP>1</SP> 2 O 3 , in which M is a bivalent heavy metal and M<SP>1</SP> is a trivalent heavy metal, comprises the steps (1) mixing the required metal oxides, (2) producing from the mixture (e.g. by pressing or extrusion) rod, bar or other shaped resistance elements, (3) maturing the resistance elements under oxidizing firing conditions, (4) re-heating the fired products in an atmosphere of a neutral gas, e.g. nitrogen, water vapour or helium, and at a temperature below or the same as the maturing temperature, (5) cooling the products in a neutral atmosphere. The method may include the following further steps: (6) selectively removing the products which have attained the required resistance, (7) re-treating the remaining products to another re-firing process in the neutral gas until they attain the required resistance. The term heavy metal means those metals which have a specific gravity of 7 or more. M and M<SP>1</SP> in the formula may be the same metals and the Specification gives as examples corresponding to the formula, Ni 3 O 4 , CO 3 O 4 , NiO.Fe 2 O 3'  CoO.Fe 2 O 3 , CuO.Fe 2 O 3  and Mn 3 O 4 . A preferred component is manganese oxide to an extent not less than 2 per cent. According to a first embodiment the starting mixture consists of 75 per cent powdered Fe 2 O 3 , 15 per cent NiO and 10 per cent MnO 2  formed into a paste with water and plasticizer. Resistance rods made from this paste are kiln matured at 1250‹ C. and then heated to a temperature below the maturing temperature-about 1150‹ C.-for 30 minutes in an atmosphere of nitrogen gas and cooled in the same atmosphere. In a second embodiment, 66 per cent of iron oxide, 14 per cent of nickel oxide, 18 per cent of zinc oxide and 2 per cent of manganese oxide are mixed by ball milling and after drying and addition of binders the resultant mixture is pressed to form small resistance bars which are then fired at 1220‹ C. and subsequently re-fired at 730‹ C. in a neutral gas. If at the end of this treatment any of the resistors fail to reach the resistance value required these are re-fired in the neutral gas until they attain the required resistance value. The resistors produced according to the invention possess a high negative resistance/temperature coefficient.
