Filed: 1928-07-26
Abstract: 316,766. Smith, W. H. July 26, 1928. Making doors.-A machine to prepare wooden doors to receive locks, hinges, &c. is built in three sections, a feeding section (not shown), a first operative section in which the door is mortised to receive the lock and hinges, and a second operative section in which the keyhole and handle recesses are bored. The door, resting on one of its long edges, enters the first operative section from the feeding section by the action of feed rollers R, its upper edge guided by rollers O<5> and is clamped vertically and horizontally by rising fences F, and presses P and P<1> respectively. The door is then mortised to receive the lock by a cutter carried on slide C<1>, and the ends of the hinge recesses cut and the screw indentations made by a cutter incorporated in the casing of the press P. The door is then unclamped and a stop S then allows the door to proceed to the third section. The door is similarly secured and the cutter J then forms the keyhole, borer K forms the aperture for the lock spindle, and the tool L forms the recesses to house the lock rim whilst the cutter E frees the marked out portions of the hinge recesses. Each tool is driven by its own separate motor, but one large power unit operates the presses P, fences F, stops S and cutter E, through shaft D, turns the feed rollers R, and controls the actions of the tools through the shafts 7 and 10 and the levers J2, K2, etc. This motor can, by the aid of a suitable clutch, be used to adjust the height of the gantries G1 and G2.

A feed through capacitor consists of a central conductor and a concentric annular electrode supported at its ends by two ceramic spacers loosely fitting on the conductor which are provided with conductive coatings on some of their surfaces which are in contact with the central conductor and annular electrode. The annular electrode may have recessed ends into which the spacers are pressed by nuts through spring washers and may be flanged and threaded externally to receive a mounting nut (Fig. 1, not shown). Alternatively the electrode may rest between the recessed edges of the spacers or it may rest between the spacers 20, 21 and be kept in position by a low dielectric constant washer 23, connected to one of the other parts to prevent rattling, and mounted on a hollow rivet 22 (Fig. 3). In this case the washer 23 may form a tube concentric with the central conductor on which the drilled out spacers may be fitted. The surfaces of the ceramic spacers in contact with the electrodes are metallized, e.g. by silver layers, and the spacers are preferably of materials having different dielectric constants.

Abstract: 245,815. Dreaper, W. P. Sept. 17, 1924. Cellulose xanthates, processes for making filaments from. - For the manufacture of viscose silk &c., yarns resembling these of raw natural silk, the threads are desulphurized in the gel condition by the employment of a bath containing a salt or salts of an alkali metal or metals in a proportion not less than 40 per cent of the saturation value, for example 80 per cent of the saturation value of common salt. A similar addition may be made to the baths used for the dyeing, bleaching and other treatment of the desulphurized threads, and also to the wash waters. Alternatively, desulphurizing and dyeing may he carried out in the same bath, provided that the salt added does not inhibit dyeing by reason of the salting-out of the dyestuff. To the final wash water, a sizing-material such as soluble starch may be added. The threads are finally dried under tension in skeins the filaments then temporarily adhering together.

Title: Improvements in electric incandescent lamps
IPC: H01K1/54
Filed: 1936-08-12
Abstract: 465,089. Electric incandescent lamps with residual gases. GENERAL ELECTRIC CO., Ltd. Aug. 12, 1936, No. 22204. Convention date, Aug. 12, 1935. [Class 39 (ii)] In order to reduce the rate of blackening of electric incandescent lamps, particularly those with filaments which are operated at a high temperature, as in optical projection apparatus, a body of material which liberates oxygen when heated is connected as a resistor in series with the filament and, by the current flowing through it, is maintained at such a temperature that it reduces the rate of blackening of the bulb. Examples of suitable oxides used for the resistor are the lower oxides of titanium, vanadium, niobium, cobalt, tungsten, &c., used either singly or mixed. Preferably, the conducting oxides are mixed with insulating oxides, such as alumina, magnesia, lime, &c., and may form a solid solution therewith. The increase in the filament resistance, due to the evaporation of tungsten, may be compensated for by the decrease in the resistance of the resistor as the latter loses oxygen. If the oxide used for the resistor has a large negative temperature-coefficient, the resistor may be also designed to reduce the initial rush of current when the lamp is first switched on.
