Abstract: Enhanced recovery of oil from subterranean sedimentary formations by an in-situ combustion method employing a pattern of an injection well and several production wells, spaced-apart by a treatment zone. Combustion is controlled by placing at least one fluid conduit in a treatment zone and introducing a control fluid through it to modify the flame front. Oxygen may be introduced to take over from combustion air initially introduced through the injection well, to sustain combustion and advance the flame front. Water may be injected through the injection well, alternating with the oxygen through the control conduit to continue a wet combustion method started with air. The strategic placing of control conduits and the introduction of appropriate fluids may be employed to improve the sweep geometry by advancing the flame front or retarding it, or invading areas behind it. Safety means is provided for introducing the oxygen at a velocity greater than the maximum flame velocity encountered in the flame front.

Multi-bit segments of each signal represent unintelligibly fragments of those signals and are stored and read-out under control of store addressing counters (36, 38, 76) whose outputs are selectively modified (48, 50) to achieve time-dispersion encryption/decryption for outgoing/incoming signals in multi-plexed writing and reading of the store (12). Digitisation (52, 54) and reconstitution (64, 66) of analogue incoming and outgoing signals is provided using inherently digital on-chip circuitry and one-bit per sample at a high rate for easy interfacing in telephone/radio systems. The whole control system can be put onto a simple semi-conductor chip of ULA type.

Abstract: A linear array of light emitting diodes (CR1-CR7) direct a diffuse beam of radiation across the path of seeds dropping down a seed chute and onto two detectors (46,48) connected in parallel, so that every seed produces a substantially equal area pulse in the output signal from the photo detectors. The signal is amplified (50) and applied to an analog to digital converter (52) producing digital samples at a high rate for processing by a microprocessor (54). The sensor value is subtracted from an offset value corresponding to the sensor signal when no seed is present and the difference signal is repeatedly added to an area signal. The offset value is adjusted from time to time to prevent the difference signal staying persistently negative or persistently positive. Whenever the area signal reaches a threshold value the passage of a seed is indicated and the area signal is decremented by an estimated area value corresponding to one seed. This estimated area value is adjusted from time to time so as to avoid long term drift in the area value, thereby maintaining the estimated area value accurately representative.

A separate welt member is securable between the two sides of the holster and presents to the frame in the region of the trigger guard, a smooth conforming surface which urges the handgun into a snug fit within the holster. A typical interchangeable welt is a thick rubber or rubber-like washer with a radius conforming to the curve of the front of the trigger guard as it joins the frame toward the front of the handgun.

Abstract: 1. A method for automatically matching the unknown impedance of an antenna to the known nominal impedance of a transmitter using a matching network having variable impedance and which is connected on the input side via a measuring head to the transmitter output and on the output side to the antenna, which network also has at least one input-side capacitive shunt arm with a variable capacitance, consisting for example of a plurality of capacitor elements which can be switched in parallel to one another and has an inductive series arm with a variable inductance consisting, for example, of a plurality of coil elements which can be switched in series to one another, which network in addition for setting its variable impedance by changing the capacitance of the capacitive shunt arm and/or the inductance in the inductive series arm cooperates with a micro-processor which controls, in dependence on the information transferred to it on the input side by the measuring head, in particular relating to the voltage standing wave ratio (VSWR) and the phase relation, the impedance setting of the matching network in the desired direction, characterized in that, to perform a standard tuning process (STA), the transformed antenna impedance presented to the transmitter output via the matching network (AN) assumes an inductive value in a first step by changing the inductance in the inductive series arm and, relative to the Smith diagram, reaches the "G= 1" circle, in that, in a second step, by changing the capacitance in the capacitive shunt arm the transformed antenna impedance is moved along the "G= 1" circle (G= 1) until the measuring head (MK) indicates the transition from the inductive zone to the capacitive zone and thus the tuning process is concluded in that, however, if the transformed antenna impedance indicates an excessively high voltage standing wave ratio, approximately VSWR > 3 when the "G= 1" circle is reached, an intermediate step is performed in the course of the second step when a predetermined voltage standing wave ratio, approximately VSWR= 3, is reached, in which second step the transformed impedance of the antenna is corrected, by further changing the inductance in the inductive series arm, in the direction of its displacement to the "G = 1" circle and in that for the completion of these process steps, the measuring head is designed in terms of circuitry to issue control information to the micro-processor (MP) in such a way that these items of control information have, in addition to information relating to the transmitting level (P), Phase (Ph) and voltage threshold ratios (VSWR) < 1,5 ; VSWR > 3), also a criterion for the "G = 1" circle (G = 1).
