Title: Synchronising means
IPC: G06F1/12
Filed: 1975-11-05
Abstract: 1533577 Data transmission, operating bistable circuits COMPUTER TECHNOLOGY Ltd 22 Sept 1976 [5 Nov 1975] 45908/75 Headings H3P and H4P The subject matter of this Specification is substantially the same as that described in Specification 1,533,576, but the claims are concerned with the synchronizing aspect of the system. As shown, synchronizing means for synchronizing the change of level of an input signal, capable of assuming either one of a first and second level, with a periodically repeating reference signal, e.g. a clock signal derived from generator 207, comprises: a bistable device 200 which assumes a first stable state in response to the first level of input signal and a second stable state in response to the second level of input signal, the device being periodically enabled by the reference signal; and means 204 responsive to any unstable condition of the bistable device 200, resulting from a level of input signal intermediate said first and second levels during the period the device 200 is enabled to respond, to generate an output signal on line 206 operable to interrupt the reference signal at a predetermined point in its periodicity and before the device 200 is next enabled, until the device 200 assumes a stable condition. Thus, the arrangement operates to recognize the occasion when the input signal is indeterminate by virtue of being sampled at a time when the signal level is changing and to delay the reference signal, i.e. clock pulse, until the signal has stabilized and therefore maximizes the available processing time per clock pulse.

Title: Prevention of bit balling while drilling wells

Filed: 1973-10-05
Abstract: 1442656 Boring earth SUN OIL CO 5 Oct 1973 [10 Oct 1972] 46533/73 Heading E1F In a process for drilling wellbores in an earth formation containing materials which attach to the drill bit, a negative electrical change is impressed on the drill teeth by providing on the drill string adjacent the drill bit, or on the bit itself between the teeth, an electrode which is positively charged relative to the drill teeth. Thus material such as montmorillite clay which develops a negative charge as loosely bound cations are swept away during drilling is inhibited from sticking to the bit. The charge may be impressed by positioning rings of a material of greater negative electromotive force than the drill bit, such as magnesium, near the bit to act as a sacrificial anode. Or a sacrificial anode may be connected to a battery in the drill bit sub, or to an electrical source at the surface.
