Abstract: ABSTRACT OF THE DISCLOSURE    A first detector estimates a condition wherein the temperature of a catalytic converter is lower than a predetermined level above which the converter operates effectively.  A second detector detects a condition wherein the engine is in an idling condition.  An ignition timing retarding device retards the ignition timing of the engine by a certain amount when operated.  An idling speed increasing device increases the idling speed of the engine when operated.  A control unit causes both the ignition timing retardomg device and the idling speed increasing device to be operated when the first and second detectors estimate and detect the respective conditions simultaneously, and causes both the devices to be inoperative when at least one of the first and second detectors fails to estimate and detect the corres-ponding condition.

Abstract: ENCAPSULATION PROCESS     Gerhart Schwab and Gerald T. Davis Abstract of Disclosure A process for the preparation of oil-containing microcapsules by interfacial condensation of a polyfunctional amine with a poly-functional wall-forming material is disclosed.  Microcapsules produced by this process have utility in the manufacture of carbonless copy paper.  The process comprises emulsifying a mixture of a hydro-phobic phase, which includes an oil, a chromogenic material and an oil soluble polyfunctional wall-forming material and a hydrophilic phase, which includes water, a water soluble emulsifying agent and a water soluble salt of the desired polyfunctional amine.  The amine salt may be formed in situ in the hydrophilic phase before the emulsi-fication step.  After emulsification, sufficient base is added to the ; emulsion to convert the polyfunctional amine salt to a polyfunctional amine and to neutralize acid formed during subsequent condensation reactions, thus initiating the reaction of the polyfunctional amine with the oil soluble polyfunctional wall-forming material and thus forming microcapsule walls around droplets of the hydrophobic phase.

Abstract: A B S T R A C T            F12313/A3406        CHANNEL ZERO SWITCHING          G. Chopping ARRANGEMENTS FOR DIGITAL         R. V. Moberly TELECOMMUNICATION EXCHANGES       A. S. Philip It is an emerging international telecommunications requirement that all 32 channels of the p.c.m. multiplex must be switchable. The switching of channel zero relates to the "spare bits" not defined for synchronisation purposes and these bits may be used as a data-bearer for network administration or control purposes. Digital telecommunication switching network, therefore, must be capable of concentrating channel assemblies of these spare bits into one transmit multiplex which may be connected to a spare bit data processor remote from the switching network or co-located with it.  The passing of channel zero into the switch block, however, is dangerous because if this data is passed across the switch block to another digital line termination unit DLT in a time slot other than channel zero then that receiving DLT will be called upon to transmit data containing two valid sets of sync and non-sync patterns which could confuse the synchronisation circuits associated with the digital transmission system connected to that DLT.  Such an arrangement is prevented using equipment in the receive and transmit DLT's.  In the receive DLT after the incoming synchronisation channel has fulfilled its synchronisation purpose it is deliberately modified such that when switched to a transmit multiplex it will not be erroneously recognised as a sync channel. The modification does not of course cause loss of information contained in the spare bits or alarm bit.  At the transmit DLT a decision is made as to whether the international bit in the sync pattern and the international bit and spare bits in the non-sync pattern should be transmitted to line as data ones or the patterns received.

Abstract: ABSTRACT This invention relates to the treatment of living plant cells by altering their interaction with charged species in their environment.  In particular, the invention relates to a controlled modification of plant-cell growth behavior by the application of encoded electrical information. More particularly, the invention provides for the intra-cellular applica-tion, via non-contacting direct inductive coupling, of one or more electri-cal voltage and concommitant current signals conforming to a highly specific pattern.  An electromagnetic treatment device developed for this technique comprises a magnetic circuit including two axially spaced electrical coils connected for excitation in flux-aiding relation and a retainer adapted to fixedly hold said coils at a spacing to thereby define a treatment zone between the coils, whereby upon excitation the coils establish a flux-development axis through the zone.  A non-paramagnetic device is adapted to support living plant cells and to provide a moist environment of such supported cells within the treatment zone.  An electric circuit excites the magnetic circuit with a repetitive low-voltage signal cycle designed for such electromagnetic coupling to the plant cells as to induce a specific non-linear electrochemical cell response.

Abstract: ABSTRACT         A well testing tool system for isolating verti-cally spaced portions of a well bore and measuring well conditions such as pressure, and temperature.  The system includes a wireline supported tool train and a locking sub connectible on a removable lock mandrel for releasably locking the tool train in a well bore.  The tool train has a locking probe releasably connectible in the locking sub, a probe mandrel connected with the probe, an equalizing valve and shock absorber, and a gauge for measuring an operating condition in the well.  The locking sub permits insertion of the probe at a low force and requires a larger force for withdrawal.  The locking sub grips the probe with a force directly proportional to the pressure differential across the locking sub.  The equalizing valve and shock absorber provides for pressure equalization across the tool train during handling and absorbs shock to protect the measuring device.  Two forms of the valve and shock absorber are spring biased open.  Another form is spring biased closed.  Each form of the valve and shock absorber is a telescoping assembly having a longitudinally movable spring biased valve member in a housing and a shock absorber spring between the valve member and housing.
