Granted: 1914-10-22
Abstract: 24,424. Brookes, A. Oct. 28. Drawings to Specification. Embossing.-Flat prints are embossed in imitation of oil paintings &c. by means of a die prepared as follows. A transparent sheet, such as glass, celluloid, &c., is placed on a copy of the print and coated with paint, such as ordinary artists' oil-paint or pasteloid, and the required lines &c. representing the relief effects are then scratched through the paint to the transparent surface by means of a handtool having a single point or a row of points. This plate is used as a photographic negative or transparency for the photo-production of the relief block or matrix in known manner and the prints are embossed by this block or matrix. Canvas texture is produced on the prints (1) by using a transparent plate lined in representation of canvas markings, in conjunction with the paint negative described, when printing to produce the relief block, or (2) by pasting and pressing canvas on the back of the print. The embossing block or matrix may be flat or cylindrical.

Granted: 1915-06-24
Abstract: 24,450. Allgemeine Elektricitõts Ges. Jan. 29, [Convention date]. Transformers.-A valve f shuts off automatically the supply of air to an electric transformer upon an outbreak of fire in the filter a, and, at the same time, allows air either filtered or not, to pass into the machine k from another source h, The valve plate f is held in the open position by means of cords b drawn out tightly by weights c; the cords ignite upon an outbreak of fire in the filter a, and the plate f closes the opening c and opens the opening of the source h. Other valves or devices may be operated to supply fresh cooling air to the machines when the main supply is cut off; the cooling air may, in some cases, be caused to enter the machines by the passages normallyserving for the exhaust, the directions of the cooling air through the machines thus being reversed.

Granted: 1914-11-26
Abstract: 3479. Warwick Machinery Co., [General Electric Co.]. Feb. 10. Regulating.-Relates to governing-mechanism for turbines of the low-pressure or mixed-pressure kind designed to be primarily driven by lowpressure fluid, for example the exhaust from highpressure prime movers, such mechanism being responsive both to the turbine speed or load and to a device responsive to pressure or flow. The admission of low-pressure fluid is controlled by a single valve located in a by-pass so that fluid in excess of that required by the turbine is by-passed to the turbine exhaust. The exhaust conduit 3, Fig. 2, of a high-pressure reciprocating engine is connected to a low- or mixed-pressure turbine 4 having a high-pressure valve mechanism 5 for admitting live steam from a conduit 6. The valve mechanism 5, together with a valve 10 in a by-pass 9 connecting the conduit 3 with the turbine exhaust conduit 7, is operated as shown by an hydraulic motor 13, which is controlled by a pilot valve 16 having its stem 17 attached to a floating lever 18 operated at one end by a speed governor 19 and at the other end, through links 20, 21, 26 and a lever 24, by a diaphragm 22 subjected to the pressure in the conduit 3. The connexions are arranged so that the valve mechanism 5 does not admit live steam until the valve 10 is substantially closed. The valve stem 17 may also be controlled by the pressure in the conduit 7 by means of the diaphragm 27 and the connexions 28, 29, 25. A flow-responsive device comprising a float 22<1>, Fig. 3, arranged in the conduit 3 may be used instead of the pressure-responsive device 22 to actuate the lever 24.

Title: Component conveying device
Inventor: SAITO KOJI
IPC: B65G47/28
Filed: 2000-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a component conveying structure capable of conveying a square-pole-shaped electronic component. SOLUTION: A magnet row comprising a plurality of permanent magnets 40 is arranged with an offset amount OS at which a row direction center separates from a passage center of a conveying passage 11 in the passage width direction, so that chip components CC intermittently moving through the conveying passage 11 receive a pulling force shown by a broken line in Fig. 7 from the magnet row. As a result, one side surface of the chip component CC adheres to the lower surface of the conveying passage 11 and the other side surface adheres to the width directional side surface of the conveying passage 11.  Since a force for correcting a component attitude with the pulling force of the magnet row is operated to the chip components CC intermittently moving through the conveying passage 11, the chip components CC can be conveyed in a suitable attitude, unsimilarly to the conventional fact that the chip components CC rotate about an axials to provide a rhombic shaped attitude.
