Patent EP-0315221-A2 (EP)
Inventor: BARR JOHN DENZIL
IPC: E21B10/567
Filed: 1986-02-21
Abstract: A rotary drill bit comprises a bit body having a shank for connection to a drill string, a plurality of cutting elements mounted at the surface of the bit body, and a passage in the bit body for supplying drilling fluid to the surface of the bit body, each cutting element comprising a thin hard facing layer, for example poly­crystalline diamond, bonded to a less hard backing layer, for example tungsten carbide. The maximum instantaneous load to which each cutting element may be subject in use is reduced by reducing the thickness of the cutting element. The thickness of cutting element necessary to achieve the required object is defined, alternatively, in terms of the absolute dimensions of the cutting element or backing layer, in terms of the relative thickness of the backing layer and hard facing layer, or in terms of the thickness of the cutting element or backing layer in relation to the overall dimensions of the cutting face.

Abstract: A device for measuring the proximity of a metal object, and a sensor for such a device are disclosed. The device includes a drive and sense coils 220, 230 which are loosely coupled together. The drive coil is driven by a square-wave drive signal, controlled by a micro-processor 200. The amplitude of the signal sensed by the sense coil 230 in response to the drive signal is dependent upon the proximity of a metal object. Sensing circuitry 250, 290 is provided for measuring the amplitude of this signal to derive a signal indicative of the proximity of the metal object. In particular, a multiplexor 280 is provided for sampling predetermined parts of the signal, (which exhibits a time-dependent change when a metal object is proximate). By ignoring the initial part of each half cycle of the received signal, effects due to conductive but non-metallic proximate objects may be ignored. A particular application of the device is for sensing the depth of reinforcing iron bars in concrete. A novel form of sensor (figure 3) is also disclosed.

IPC: H05G1/36
Filed: 1988-01-22
Abstract: A voltage signal (29,42) proportional to the brightness of an x-ray image is derived. In a mA loop the ratio of a reference voltage to brightness is determined (in 70). If the brightness ratio does not equal 1 it causes the x-ray tube current controller (21,61) to adjust current (mA) to eliminate the error. A command proportionate to the ratio is stored (in 71) until the next image frame. In a kV loop a ratio of the last mA command and a set limit for mA is taken (in 80). This error ratio is multiplied (in 83) by the brightness ratio to provide a kV control ratio indicative to how much of the brightness error the kV loop is obliged to correct. The kV control ratio is corrected for nonlinearity between kV change and brightness change and the resulting command is used to adjust the kV applied to the x-ray tube anode. In a video gain control loop a ratio is taken (in 110) between the stored last brightness ratio of mA command and maximum mA command limit and the brightness change resulting from the last kV control command is ratioed (in 114) to the maximum brightness factor limit. The result of multiplying (in117) the last two mentioned ratios and the brightness ratio is the new video gain (VG) control signal. The VG signal is used to adjust the f-stop of the video camera and the electronic gain to change brightness.

Abstract: A data compression system implementing expansion protection employs one or more pairs of FIFOs to compare the lengths of raw and processed versions of a block of received data. A data compression system includes a data compressor (11), a controller (19), a FIFO (13) for compressed data, and another FIFO (15) for uncompressed data. The FIFOs (13 and 15) are used to compare the length of a data block processed by the data compressor (11) with the raw version of the data block. The shorter version is transmitted so that the data transmitted by the data compression system is at most negligibly expanded relative to the system input. A code injector (17) inserts a code into the output stream to indicate the beginning of the transmission of a raw data block so that a receiving or retrieving system can determine whether the data following needs to be decompressed or not. Further codes can be injected to indicate a switch from raw data to processed data in the output of the compression system.

Abstract: The invention relates to a collision-preventing control system for two cutters, to be moved towards one another, of a computer-controlled cutting installation. With this control system, it is possible to detect the actual position of each cutter during the cutting process. The proximity of the two cutters can be determined and compared with a previously set tolerated proximity via comparators arranged in the arithmetic unit. As soon as the tolerated proximity is reached, the control system switches the cutting installation off. In addition, an electrical safety circuit is specified, by means of which it is not possible for the cutting installation, after being automatically switched off, to start up again automatically.

Abstract: A battery is divided into a plurality of battery blocks. A current flowing into a coil is rapidly changed by a switching element so as to raise the output voltage of one battery block. The power of the battery block is trans­ferred to another battery block by utilizing the thus-raised voltage. This operation is subsequently repeated for each battery block. Thus, all the blocks are subsequently completely discharged for achieving the equalization of the amount of charge of each block.

Abstract: To manufacture an exhaust-tube-less lamp vessel with a vacuum atmosphere, particularly a glass envelope (1) of quartz glass for a discharge vessel (2), wherein the glass envelope (1) is closed at one end by a cap (1'), the envelope is initially crimped only in the immediate area of the sealing foils (4).

The lamp vessel (19) is finally sealed off with the aid of spot burners (18), by means of which the capillaries (12) are melted shut at the centre of the side face (11') of the crimping (11), leaving sealing points (20). Finally, the tube section of the glass envelope (1) protruding past the crimping (11) is separated and a base is attached to the lamp vessel (19). <IMAGE>
