Abstract: 298,832. Oettinger, R. Feb. 6, 1928. Casting-machines. - The hand sling type of centrifugal casting- machine for dental and like casting is modified to permit forcing of the metal into the mould by fluid pressure. The mould is supported in a pan 1 carried on side rods 2 detachably connected to a cross-bar 3 attached by a tie 4 to the handle. A lid 6 formed to cover the mould completely and to seat on the rim of the flask by asbestos washers 12, slides on the rods 2 and is suspended initially by a rubber ring connecting the hooks 8, 9. When the mould is slung, centrifugal force breaks the ring and causes the lid to seat over the mould. If sufficient air pressure is not thus generated to charge the mould the washers may be moistened for steam generation. In a modification the cross-bar 3 is detachably and pivotally mounted in a balanced frame rotatable on a spindle secured to a table &c. A handle on the axis of rotation serves to apply hand braking to bring the apparatus to rest. Flasks.-The flasks may be circular or oval and provided with a flanged base 15 perforated at 16 to register on pins in the pan.

Patent GB-868592-A (GB)
Title: Improvements in or relating to time delay circuits
IPC: H03K17/28
Filed: 1958-02-07
Abstract: 868,592. Transistor circuits. IGRANIC ELECTRIC CO. Ltd. Feb. 7, 1958 [March 7, 1957], No. 4080/58. Class 40(6) A time delay circuit comprises a resistancecapacitance charging network, a normally non- conducting transistor and means for relatively initiating conduction of the transistor and the charging of the capacitor, the latter being connected between base and collector of the transistor during the charging period. The Figure shows a transistor 9 connected in series with a relay CR across a D.C. supply 7, 8, 10. A capacitor 14 is connected through a resistor to a tap on a potential divider 12 so that it normally charges up with its lower plate positive with respect to its upper. Upon actuation of a switch 15 the lower plate is connected to the base of the transistor causing the transistor to conduct and accordingly the potential at the collector suddenly falls until an equilibrium state is reached in which the transistor conducts slightly. The condenser thereupon commences slowly to discharge in "miller" fashion and the collector current to rise and become sufficient to operate the relay. Upon opening the switch the relay is released and the condenser re-charges. The recharging may be speeded by connecting a diode across resistor 13 and a contact across any load which exists in the collector circuit to short the load when the switch 15 is opened (Figs. 2 and 3, not shown). Alternatively the emitter-collector path of a transistor may be connected between the negative supply terminal and the upper terminal of the capacitor and the base emitter path across the resistor in series with the capacitor so that when the condenser commences to recharge the transistor is rendered conducting so as to provide a direct recharging path to the negative supply (Fig. 4, not shown). In a further alternative arrangement (Fig. 5, not shown) switch 15 is replaced by a short circuit and the operation is initiated by a switch connected across the potential divider resistor 11 so that the commencement of the discharge of the condenser is effected without the initial current surge through the transistor. The relay may alternatively be connected in series with an amplifier transistor having its base emitter circuit connected across a resistor in the emitter circuit of the transistor 9 (Fig 2, not shown). It is stated that the relay may be replaced by the control windings of a saturable reactor or a magnetic amplifier.

Title: Improvements in or relating to the manufacture of blasting or like fuses of a cord-like nature
IPC: C06C5/00
Filed: 1927-02-15
Abstract: 295,731. Fritzsche, J. Feb. 15, 1927. Coating-compositions applied melted.-A protective waterproof covering for blasting or mining fuzes of a cord-like nature is formed by applying to the fuze a material serving as a substitute for rubber, and composed principally of a substance or mixture of substances that has or have undergone vulcanization, polymerization, or oxidation, and causing the substance to set by cooling to a flexible coating possessing the required properties. Substances which, when vulcanized by treatment with sulphur or sulphur compounds, may be used in carrying out the invention include fatty oils and stearin pitch or stearin bitumen. Rubber substitutes such as factis or artificial caoutchouc, and polymerized or oxidized oils, such as linoxyn, are also mentioned, and processes involving the vulcanization of stearin pitch, or the polymerization of linseed oil, or the oxidation of wood oil - are described in detail. In each of these processes, a hot mass is formed, through which the fuze is drawn, the excess of coating material being stripped off by a ring or nozzle. To remove tackiness, the surface may be sprinkled with talcum or the like. Numerous fillers and other ingredients which may be added during the preparation of the coating material are specified, and include resin, kaolin, and cotton. The material, which is of such a nature that after application to the fuze in a plastic or liquid state it will set or harden, but remain pliable may serve as a coating to the core or its wrapper, or to the covering of yarn or tape-like material usually employed. Several successive coatings may be applied, some of these being intermediate between layers of yarn or the like,. and the coatings may vary in composition. A layer of chalk, &c. may be interposed between a coating of the waterproof material and a covering of yarn, &c., and an external coating of powdered metal, paint, or enamel, &c. may be applied.
