Granted: 1986-03-27
Abstract: A circuit arrangement for generating an actuating voltage for a piezo-electric element (1) of a positioning device intended for positioning a recording and/or reproducing head relative to an information track. A control signal whose amplitude is representative of a positional error is applied to a signal conversion stage (7) in the form of an amplitude modulator. The modulator output signal is applied to the primary (10) of a transformer (11). The piezo-electric element is connected to the secondary (12) via a bipolar switching device (13) which is actuated by a periodic pulse-shaped switching signal which, by means of a pulse-shaper stage (20), is derived from a carrier signal supplied by an oscillator (18). The switching signal corresponds in time to only one of the two peak amplitude values of the carrier signal and has a pulse width less than half the period of the carrier signal.

Abstract: A crystal (1) of a wristwatch case contains a sapphire base plate (2) which, in front view, entirely covers the body (3) of the case. That plate (2) is in turn entirely covered by a second sapphire plate (4) which is glued (5) to plate (2) very rigidly. The crystal (1) is fastened to the body (3) by screws engaged from the back side of the body (3) in sockets (7), a head (9) of which is captured between the two plates (2, 4) of the crystal (1). The position of the sockets (7) is exactly determined by a conical seat (10) of housings hollowed out in plate (2), at the bottom of which rests the conical head (9) of the sockets (7). Flats (14) are formed on the heads (9), so that the glue forms packings (15) preventing the sockets (7) from turning while screwing the crystal (1). The upper face (6) of the square (3) and the heads (9) of the sockets (7) are masked by a metal coating (12) deposited by vacuum spraying on the other side of plate (4). The crystal (1) is, furthermore, decorated with semicylindrical colored sapphire baguettes (16) glued in corresponding grooves (19) of plate (4).

Title: An improved controller for a videotape recorder, and a method therefor
Inventor: CORKERY JOSEPH L
IPC: G11B27/13
Filed: 1983-07-05
Granted: 1988-10-27
Abstract: An improved controller for a VTR is disclosed. The VTR has a time code reader and a tape time reader, each generating a signal representative of the time length of the material recorded on the tape. The time code reader generates a signal derived from the time code recorded on the tape. The tape time reader generates a signal derived from the signals generated by a tachometer, connected to the tape transport mechanism. An interpolated time code is generated by means which adds an offset value to this tachometer derived time data. The offset value is periodically calculated by means which determines the difference between the time code data and the tachometer time code data after first determining that the tape speed has exceeded a predetermined threshold speed for a predetermined period of time. If the tape speed has not exceeded this predetermined threshold speed, then the last calculated offset is added to the tachometer derived data.

Abstract: A method for the gaseous reduction of iron ore to sponge iron in a vertical shaft moving bed reactor (10) wherein a hot gaseous mixture of hydrogen and a carbon monoxide is used to reduce the ore. It has been found unnecessary to use the external catalytic reformer of prior art processes to reform the methane and other hydrocarbon constituents of the natural gas commonly used as a source of gaseous reductants. By establishing a reducing gas recycle loop to which make-up natural gas and steam are fed in the proper proportions, the product sponge iron in the reactor (10) can be used to catalyze hydrocarbon reformation, provided that the carbon content of the recycled gas is maintained low by removing carbon dioxide therefrom. When pure methane is employed, steam/methane molar ratios within the preferred range of 1,4 : 1 to 2.2 : 1 are used.

Abstract: A plug for a probe nose is produced in one piece having two contiguous parts. The first part is a substantially cylindrical body designed to be inserted in the probe nose such that it ensures tightness between the probe and the plug body. The second part is a substantially conical or semi-spherical head, co-axial to the body and provided at the level of its junction with the latter with a shoulder by which it can abut on the end of the probe. The plug comprises an inner through conduit which connects the surface of the head with the free front face of the body. This conduit authorizes the discharge of a protective gas introduced into the probe, and it is possible by controlling the flow of this gas to assess the difference of pressure exerted on each side of the plug and to adjust accordingly the pressure of the protective gas in order to prevent both the ejection of the plug and the penetration into the probe of hot gases from the furnace. The invention finds an application in the probing of furnaces used for reducing materials containing pressurized gases, such as blast furnaces.
