Abstract: POWER CONTROL MEANS FOR ELIMINATING CIRCUIT TO CIRCUIT DELAY DIFFERENCES AND PROVIDING A DESIRED CIRCUIT DELAY                            Abstract An on chip delay regulator circuit which varies the power in logic or array circuits on the chip so as to minimize, or eliminate, chip to chip circuit speed differences caused by power supply variations and/or lot to lot process differences, temperature, etc. is described.  The on chip delay regulator compares a reference signal to an on chip generated signal which is sensitive to power supply changes, lot to lot process changes, temperature, etc.  The comparison creates an error signal which is used to change the power (current or voltage) supplied to the on chip circuits.  By changing the circuit power, the circuit speed (gate delay) is increased or decreased as necessary to maintain a relatively constant circuit speed on each chip.  In an example a plurality of integrated circuit chips each contain an on chip delay regulator.  The on chip delay regulator on each chip of said plurality of integrated circuit chips receives and responds to the same signal (or clock).  Each chip provides a discrete on chip generated signal related to the parameters of the chip.  The gate delay (or speed) of the circuitry on each chip is determined by its on chip delay regulator under control of the common reference signal (or clock).

Abstract: Abstract of the Disclosure Enhanced recovery of oil from subterranean sedi-mentary 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.

Abstract: ABSTRACT The invention relates to a method for transposing sub-bands of equal width in a signal-frequency band by means of modulators followed by equal band-pass filters and additional modulators, characterized in that specific carrier-frequencies are permanently assigned to the modulators, and in that arranged between the band-pass filters and subsequent modulators is a switching matrix for scrambling the sub-bands.  The method according to the invention has the advan-tage that there is no need to switch over between the carrier-frequencies fed to the modulators and this produces a saving in circuit costs.   In a further devel-opment of the invention, the pass-band of the band-pass filter is applied to one of the sub-bands, thus dispensing with two modulators and the production of a carrier-frequency.  According to further configurations, favourable values are given for scrambling a CCITT speech-channel.

Abstract: ABSTRACT OF THE DISCLOSURE         A screw feed apparatus is provided herein for use with a power screwdriving tool.  The screw feed apparatus includes an internally threaded adapter detachable by threads to an externally threaded shank portion of said tool with an elongated driver member detachable at one end to a chuck formed with the shank portion and a casing relatively slidably mounted on the adapter. At least one spring is disposed within the casing, for urging the adapter axially outwardly.  A pair of brackets is mounted to a forward end of the casing and is provided with guide means for guiding a flexible magazine belt in a direction transverse to a longitudinal axis of the tool, the magazine belt carrying a series of self-drilling screws which are aligned in line and spaced at a regular pitch.  A pair of feed sprocket wheels is disposed within the brackets, for feeding the magazine belt intermittently by the regular pitch.  A nose piece is mounted to a forward end of at least one of the brackets, for providing a predetermined distance of screw-receiving space between the forward end of the brackets and a workpiece into which the self-drilling screws are driven.  A ratchet wheel is supported by one of the brackets so as to co-rotate with the pair of feed sprocket wheels.  A slide member is supported on the casing so as to be axially slidable back and forth rectilinearly, the slide member being so arranged as to move toward the ratchet wheel in response to forward movement of the adapter, and to move away from the ratchet wheel in response to rearward movement of the adapter.  Finally, a claw means is operatively supported by the slide member so as to force the ratchet wheel to rotate intermittently by the regular pitch as the slide member moves away from the ratchet wheel.  This permists a decrease in the size and weight of Abstract Cont.   the apparatus as well as greater efficiency in operation by diminishing a forward stroke of a screwdriving tool in each working cycle.  The screw teed apparatus is provided with a positionally adjustable nose piece to be pressed against a workpiece and with means for preventing undesirable disengagement of a driver member from a chuck of the screwdriving tool.
