Title: Well logging system and method
IPC: G01V11/00
Filed: 1979-10-10
Abstract: A well logging system and technique is provided for correlating historically derived measurements with new measurements being derived at correlative depths as the well is logged. A logging sonde generates and delivers to the surface digital logging data in realtime as a function of preselected depth intervals. This data is merged with compatible digital data which is historical in character and derived at correlative depths. The realtime and historical measurements derived at the same borehole elevations are correlatively matched for realtime recording, display and processing of the matched data. A converging technique is provided for accomplishing the initial merger independent of the direction of logging, the relative starting elevation of the sonde and historical data, and whether the realtime logging has begun prior to the merging process. Provision is made for transmitting from one or more remote observation and control sites the historical data employed in the merger, for transmitting the merged data to a remote location, and for transmitting from the remote location to the well site control signals in response to the merged data received by the remote site.
Patent GB-2044518-A (GB)
Title: Low loss apertures for ring laser gyros
IPC: H01S3/083
Filed: 1979-11-07
Abstract: A gas discharge ring laser formed in a glass-ceramic block has a reduced bore section of diameter d for suppressing unwanted TEM modes. The invention makes use of the fact that the gain available from the excited gas of the laser cavity falls off near the walls of the cavity. Thus, the diameter of a portion of the tube enclosing the excited gas is made sufficiently small so that the gain available to both the TEM00 and TEM01 modes is reduced gradually to zero at the cavity wall. Because of the different light distribution in the two modes, the overall gain for the TEM01 mode is significantly less than for the TEM00 mode, thus preventing the TEM01 mode from oscillating. <IMAGE>

Title: Data processing systems
IPC: G06F7/48
Filed: 1979-12-14
Abstract: In a microprogrammed data processing system the throughput of the system is increased during the processing of decimal numeric instructions by apparatus which, in advance of receiving the operands, is conditioned by instruction descriptors to align the decimal digits of the operand words. As the words are received from memory they are aligned and processed. The apparatus responds to the descriptors which indicate the characteristics of the operand being processed, e.g. whether the operand is a floating point or a scaled number, has 4-bit decimal digits or 9-bit decimal digits, is long or short etc., to enable the proper microprogram subroutine.

Title: Monitoring lighting systems
IPC: H02J9/02
Filed: 1982-03-26
Abstract: In an emergency lighting system comprising a plurality of lights (6) which are connected in parallel and supplied by a battery 4, the lights only being energised when the mains fails, a monitoring circuit continuously checks the state of each light whilst the system is not being energised from the battery. A constant voltage source (7) whose voltage is less than that of battery 4, is connected to the system via a current measuring resistor (8). The measured value of the current is evaluated by an amplifier (9) and comparator (10) and an indicating device (11, 12) is triggered if a predeterminable value is exceeded. At each light (Figure 2, not shown) a first threshold switch (26) monitors the voltage on supply conductors 20,21 and closes to energise the respective light only when the voltage corresponds to battery 4, rather than source 7. A resistor and indicator (27,28) bypassing this switch permit a small monitoring current to flow through the light from source 7 when the battery is disconnected. If the light fails, a second threshold switch (29) at the light switches in an extra load on to conductors 20,21, thus drawing increased current from source 7 to trigger comparator 10. <IMAGE>
