Patent EP-0422706-A2 (EP)
Inventor: CASSO CHRISTOPHER
IPC: E21B47/04
Filed: 1990-09-18
Abstract: Methods and apparatus for accurately determining drill bit depth are provided. A hook load is sampled at a rate of at least 4 Hz and is compared to a load threshold to establish a slips-in condition. A determination is made retroactively that the drill string stopped moving when the hook load passed through a high dynamic threshold. On the slips-out procedure, the identical high threshold is used, with movement established when the hook load exceeds the high threshold. The high dynamic threshold corresponds to the points at which the drill string actually stops and starts moving in the slips-in and slips-out procedures. The apparatus provided is a drawworks encoder mounting assembly which retrofits an auxiliary brake section of the drawworks or the rotary seal air coupler of a drawworks clutch. A split ring gear fits around and is secured to the rotating cylinder of the rotary seal air coupler. The split ring gear is part of a pulley having another gear and a drive belt, such that rotation of the drum and rotorseal air coupler cylinder is translated to a shaft of an encoder coupled to the second gear. The encoder thereby tracks the rotational movement of the drawworks drum. At desired times, also provided is a second encoder which is part of a calibrator which, via a calibrator wire, precisely measures the location of the travelling block relative to a known vertical location. The first and second encoder readings are compared continuously and are used to provide excellent calibrations between the drum rotation and the travelling block movement.

Abstract: In a photographic film cassette, rotation of a spool in a direction of unwinding a photographic film causes a film leader to advance to an outside of a cassette shell. An exposed film is drawn out of the cassette shell after advancing the film leader for developing the exposed film in a state with a film trailer attached to the spool so as to keep the cassette shell reusable. The exposed film is wound up into the cassette shell after development. The spool is rotated in the unwinding direction in a printer in order to advance the film leader outward. The exposed film is drawn out of the cassette shell frame by frame after advancing the film leader for subjecting the developed film to printing in a state with the film trailer attached to the spool. The spool is rotated in a direction of winding up the developed film after printing for containing the exposed film in the cassette shell.

Abstract: A method is specified for controlling a light barrier in which a number of cooperating transmitters and receivers form a plurality of scanning beam paths, the scanning beams more or less filling a region to be monitored of an object to be monitored. Scanning cycles in which the presence of essentially all the scanning beams is detected are triggered by the object to be monitored or a control device cooperating therewith, said control unit transmitting at least one external control signal to an external unit, depending on the scanning result. This method temporarily forms a paired assignment of one transmitter and one receiver each as an operating scanning beam path, at least one calibration cycle being carried out in accordance with the operating scanning beam paths of the light barrier for the purpose of self-control of individual operating characteristics of respective transmitter/receiver pairs. Moreover, a scanning window is opened by a control function of the unit to be monitored by means of a control unit in which at least one scanning cycle of the operating scanning beam paths is performed. A light barrier for transmitting a control signal, which has a number of cooperating transmitters and receivers, transmitters or receivers being activated in scanning cycles by an evaluation circuit, which light barrier is equipped for carrying out the abovementioned method, has an evaluation circuit which is constructed as a calibratable evaluation circuit [1] for the self-control of the operating setting variables of the respective working scanning beams [S] [transmitter/receiver pair] and the activation series of the working scanning beams [S] of the light barrier. Said evaluation circuit contains a control circuit [2] which is connected to read and main memories [2.1 and 2.2, respectively] and to a clock [1.3], as well as to the object to be controlled by means of a control output [As] for an output control signal and an input [E3] for an input control signal. Moreover, it has assignment means which for a phase of the operation in each case temporarily assigns to one another in each case one transmitter [3.1.1, 3.1.2, etc.] of a transmitter circuit [3] and in each case one receiver [4.1.1, 4.1.2, etc.] of a receiver circuit [4]. <IMAGE>

Abstract: A double acting hydraulic drilling jar 1 includes a mandrel 2 arranged in a housing 3 for sliding longitudinal movement. A hammer 69 is positioned on the mandrel 2 and interacts with anvil surfaces 64, 66 in the housing 3 to deliver both upward and downward jarring forces to a drill string. A hydraulic valve arrangement permits the storage of large amounts of static force before releasing the hammer 69 to strike the anvil surfaces with great force. The hydraulic valve arrangement includes a tripping valve 95 positioned to be actuated by a first pair of engaging surfaces in response to downward movement of the mandrel 2 in the housing 3 and a second pair of engaging surfaces in response to upward movement of the mandrel 2 in the housing 3. Thus, independent control over the upward and downward jarring action is achieved.

Abstract: A duplicated transmission system in which two optical wavelengths (λ 1 ,λ 2 ,λ 3 ,λ 4 ) are utilized on each of a pair of optical links (142,144) with one optical wavelength (λ 1 ,λ 3 ) communicating data and the other optical wavelength (X 2 ,X 4 ) communicating a signal designating an active optical link of the pair. Each of the optical links is terminated on a transmit unit (101,121) and a receive unit (102,122). The two transmit units determine which of the optical links is the active optical link, and each of the transmit units then transmits a signal on the second wavelength of the terminated optical link indicating this decision. The second wavelength of the active optical link designates that it is active, and the second wavelength of the standby optical link designates that it is the standby optical link. Upon reception of the information on the second wavelengths, the receive units both select the active optical link.
