Title: Improvements in or relating to moulds for casting
IPC: B29C33/38
Filed: 1944-01-11
Abstract: 575,693. Carbon. CARBORUNDUM CO. Jan. 11, 1944, No. 531. Convention date, Jan. 12, 1943. [Class 90] [Also in Groups V and XXII] A carbon mould of skeletal structure is made by liberating carbon from a carbonaceous liquid by the action of an acid on the liquid. The reaction may or may not take place around a pattern of the object to be moulded. Loading materials such as finely divided carbon or alumina may be added to the acid or the liquid or both; glycerine may be added to strengthen the deposited skeletal carbon structure. A pattern 2, Fig. 4 of wax, sugar, or Wood's metal is fixed to the bottom of a container 3 by a stem 4. Furfural, furfuryl alcohol or a mixture of both is mixed with an acid, e.g., sulphuric or hydrochloric, in the container. When the liberated carbon is firm enough to handle, the pattern is removed by heating, e.g., in water, and the carbon dried and calcined to leave the completed mould. The rate of cooling of metals, refractories, or plastics cast in the mould may be varied in two ways:-(1) The thickness of the mould wall is reduced at 9 Fig. 6 by attaching to the inside of the container 3 a wax piece corresponding to the hollow 10. (2) The density of the mould is varied (a) by first making a main part A (Fig. 7) having an aperture and then filling this aperture (by reacting acid and furfural &c.) with a plug 11; or a preformed plug may be positioned in the container and the main body formed about it, or (b) by making the mould of stratified layers from mixes having different proportions of acid and furfural &c. Air vents may be provided for heavy density moulds. The mould may be removed by breaking or it may be allowed to burn away from the outside and the heat of burning may be utilised to anneal the moulded article. An insert 12, to be incorporated in an article cast in the mould, is supported in the mould as shown. This insert may be embedded in the mould by initially embedding it in the wax pattern.

Patent GB-368901-A (GB)
Title: Electric incandescent lamps
IPC: H01K1/62
Filed: 1931-01-08
Abstract: 368,901. Electric incandescent lamps. SITZMANN, J. M., 32, Stresemannstrasse, Berlin. Jan. 8, 1931, No. 727. [Class 39 (ii).] In electric incandescent lamps of the type wherein the intensity of illumination can be varied either by providing a number of filaments or by inserting resistances in series with a filament, the switching mechanism is disposed within the cap of the lamp and is operated electromagnetically by the switching on and off of the current. Fig. 1 shows an electric lamp bulb 2 which contains three filaments 121, 14, 15 and is secured to a cap made in two parts 1, 3, the lower part 3 being screwthreaded for insertion into an Edison type lamp holder. The electromagnet 4 disposed within the part 3 of the cap is provided with an axial core controlling an armature 5 supported on a leaf spring which is formed with an extension or pawl 6 engaging a ratchet wheel 7. A detent pawl is provided by a leaf spring 8 arranged above the armature. With the mechanism in its initial position, when the lamp is switched on current passes through the two contacts of the cap to the filament 121 connected thereto, and also through the electromagnet 4, causing the pawl 6 to be moved downwardly over the teeth of the ratchet wheel 7. The switching off of the lamp allows the pawl to return to its original position, thereby rotating the ratchet wheel which is secured to a cam 9, Fig. 2, adapted to co-operate with a contact spring 10. The spring 10 is connected to the filament 14, so that the latter is brought into circuit when the lamp is switched on again. A further rotation of the cam 9 produced by the next switching off of the lamp brings the spring 10 into contact with a contact spring 11 connected to the filament 15, which is thus put in parallel with the others and is illuminated the next time the lamp switch is operated. When adapted for use in a lamp with a single filament the cam operates to regulate resistances arranged either in the cap or in the bulb. For use on alternating current circuits the armature is provided with a counterspring 16 to retain it against the periodic interruptions of the current. The electromagnet may be rendered inoperative by providing it with a separate switch or withdrawing the core.

Abstract: 250,649. Salerni, P. M. Jan. 10, 1925. Cutlery and like blades.-In a machine for milling hollow-ground razor and like blades, particularly safety-razor blades, prior to grinding, a forged blank A is traversed by a holder C between two oppositely-rotating milling-cutters B. The base and ends of the blanks are first machined and holes A<1> are provided for engagement with conical pins C<5> in the jaws of the holder to force the base into contact with projections C<2>. The jaw C<1> is formed integral with the holder and the jaw C<3> is pivoted thereto and adjusted for engagement with the blank by a screw C<4>, the holder being fed horizontally between the cutters by hand or otherwise. The cutters are rotated about horizontal parallel axes and one is adjustable by means of a slide B<3> and screw B<5> to compensate for grinding of the teeth. Each cutter has side teeth B<1> and also peripheral teeth for finishing the surfaces of the blank as it is traversed, the teeth being arranged in the same plane and opposite each other so that the cutting pressure is balanced and chattering is avoided. In modifications a multiple holder may be employed to traverse a succession of blanks between the cutters, or a number of pairs of cutters may be mounted on parallel spindles, each pair acting on a single blank. The holes A<1> serve for locating the blade during the grinding and polishing operations and during the drilling of holes for the attachment of other parts of the razor.

Title: Electro-acoustic tranducer
IPC: G04C21/02
Filed: 1982-11-25
Abstract: An electroacoustic transducer particularly for small small-sized portable equipment such as a wristwatch comprises a first vibrating plate which is vibrated by means of an electromagnet and a second vibrating plate which is coupled with the first vibrating plate by an airtight space which acts as an air spring. The first and second vibrating plates have different natural resonant frequencies so that the vibration system comprising the two vibrating plates and the air spring coupling them with one another forms a vibration system having two resonant frequencies. A resonant air chamber superposed on the second vibrating plate has a sound radiating port and has a resonant frequency between the two resonant frequencies of the vibration system comprising the first and second vibrating plates and coupling air spring. The electroacoustic transducer thus responds to a considerable range of frequencies.
