Granted: 1913-04-24
Abstract: 28,503. General Composing Co. Dec. 11, 1911, [Convention date]. Arc-lamp electrodes.-In a "candle," a separating- body which serves for relighting consists of powdered substances agglomerated by means of a colloidal organic salt of a divalent or polyvalent metal, such as aluminium, titanium, barium, magnesium, chromium, or vanadium. Formates, oxalates, lactates, and tartrates of such metals are suitable. Basic salts may be used ; a solution of aluminium formate or titanium oxalate gives a gummv mass on evaporation. Some salts, for instance those of titanium, also assist in the formation of conductive bridges for relighting. The powder may consist of titanium dioxide, with or without carbon or graphite and a fluoride such as that of calcium or cerium. The separating-body may be strengthened by the incorporation therein of mica, asbestos, or rods, gratings, or netting. Objections to the use of water-glass, Portland cement, gypsum, magnesium oxide, magnesium-chloride, cement, zinc oxychloride, cellulose acetate, casein, gum, dextrine, tragacanth, starch, viscose, and "bakelit" as agglomerants are pointed out.

Abstract: 7165. Atkinson, H. W. March 25. Expression, controlling.-For controlling expression, a hand-operated valve and a valve controlled by the tune-sheet are provided between the action and the exhaust. Adjustable stops are provided to vary the initial positions of the valves. The tune-sheet controlling mechanism of one valve may be rendered inoperative. In a modification, the same valve is controlled either by hand or by the tune-sheet. In Fig. 1, separate pipes b, b<1> are shown for the treble and bass sections of the instrument, and valves h, c, which control ports leading to the exhaust-chest a, are provided for each pipe. A valve h is opened by the inflation of a diaphragm g when the tune-sheet admits air to a pipe i. The chamber above the diaphragm g is slowly exhausted through the leak j. A screw q is provided to adjust the initial position of the valve h. By operating a lever s, the slide r may be shifted to disconnect the pipes i from the chambers above the diaphragms g, so rendering the tune-sheet controlling device inoperative. Hand-operated valves may be provided to admit air to inflate the diaphragms g and open the valves h. The valves c are opened by depressing the push-rods c against the action of springs f. Alternatively, the valves c may be normally open. The initial positions of the valves c are adjusted by rotating a cam p to tension a flexible plate m, which bear against collars o on the rods e. In the modification shown in Fig. 6, a single valve h is provided for each section of the instrument and may be opened by the tune-sheet admitting air to the diaphragm chamber g, or by the operation of the push-rod c. A spring l is provided to take the weight of the push-rod c.

Abstract: 22,092. Melmore, W. M. Oct. 1. Cylinders, attachments to for compressing air.-An air compressor for inflating the tyres of motor-vehicles, and of the kind operated by the fluctuations of pressure in one of the engine cylinders, is constructed so that atmospheric air is drawn into the engine cylinder through the valved power piston 12 of the compressor during one stroke, while, during the succeeding stroke, atmospheric air is supplied to the rear of the piston in the pump cylinder 1 and afterwards compressed air from the engine cylinder. In the form shown, atmospheric air enters the power cylinder by way of an air-jacket 22 and ports 10 adapted to be closed by the power piston, which consists of a ported disk 4 and cup 23 containing a spring-pressed valve 15. During the upstroke of the pump and power pistons, while compressed air is being forced from the top of the pump cylinder into the tyre, the pump cylinder is first opened to the atmosphere by way of a valve 8 operated by friction with the piston-rod 3. Then upon the closing of the ports 10 by the power piston, the piston uncovers the ends of one or. more longitudinal grooves 11 to permit compressed air from the engine cylinder to pass into the pump cylinder.

Title: Method of and Apparatus for Indicating or Signalling the Rise of Water Level.
IPC: G01F23/24
Filed: 1914-03-24
Granted: 1915-06-17
Abstract: 7462. Vertriebsges. Magnet Elektrischer Apparate. May 9, 1913, [Convention date]. Indicators, alarm and signal.-In an apparatus particularly applicable for indicating the rise of water in enclosed spaces, for example in ships and mines, a thermometrical device is maintained at a temperature different from that of the water the rise of which is to be indicated, whereby upon contact with water, the temperature of the device is changed, which change is used to put an alarm in operation. A thermometer 20, Fig. 2, in a casing is maintained at a constant temperature by an electric heater 12, which is cut out through the operation of an electro-magnet 18 when the mercury rises to a contact c in the thermometer tube. Upon water entering the casing, the water falls below a second contact b, thus breaking a circuit containing an electro-magnet 15, the armature of which then closes a circuit 9 containing the alarm. In a modification, the change of temperature of a resistance causes the strength cf the current passing through the resistance to alter and thus operates an alarm in the manner described above.

Title: Improvements in or connected with Ticket Punching Apparatus.
Inventor: PRESCOTT GEORGE
Filed: 1913-07-24
Granted: 1914-07-24
Abstract: 13,324. Prescott, G. July 24, 1913. Ticket punches.-Locking-means are provided whereby the punch bar may be locked by the conductor from the exterior and unlocked by the opening of the punchings-chamber door, the last-named operation also serving to remove a lock from a spring-controlled shutter which may be drawn down manually, while the door is closed, to cover the reading apertures of the counter, and remains locked in that position. The closing of the punchings-chamber door also unlocks the punch bar, if the lock has been previously operated. The door 20 of the chamber 5 has pivoted therein an inner door 21, between which and the main door a paper seal is inserted, the seal being broken by the insertion of a pin in an aperture 50 to engage a hole 49 in a spring-controlled bolt 45 carried by the door 21. A spring catch 27 serves, by engaging a flange 25 of the door 20, to hold the door in the closed position, the flange being cut away as shown in Fig. 2. Inward movement of the door 20 serves, through a pin 29, to keep the catch 30 in engagement with a notch 31 in the lowered counter shutter 23. The punch slide is locked by a spring-retracted pawl 36, Fig. 6, adapted to engage a notch 39 in the punch slide 16 and held in that position by a bladespring 35 which presses against the face of the pawl. When the catch 27 is moved back by the closing or opening of the door, the spring 35 is moved thereby to release the pawl, the top of which is cut away to allow this. A pin 40 protruding through a slot 41 in the casing allows the conductor to move the pawl, against its spring 38, to the locking position, wherein it is held by the spring 35. The release of the door from the catch 27 is effected by an inclined part on the bolt 45, limited in movement by a screw 47 and a slot 48, engaging a pin 52 on the catch 27. The first movement of the bolt 45 allows the pin 29 to move out in front thereof. the casing 21 being cut away for this purpose. and thereby prevents the door from being closed again and releases the shutter 23. To allow a new seal to be inserted the bolt is moved by the pin 47 until the inclined part is opposite a gap in the flange 55 whereon the bolt may be moved fully out.
