Abstract: FIXATION LOOP FOR TRANSVENOUS LEADS               Abstract of The Disclosure Transvenous leads including an outer atrial and an inner ventricular spaced wound coils coaxial with respect to each other and including a closed fixation loop connected to the outer lead.  The closed fixation loop extends out-wardly at an angle with respect to the outer lead.  An inner lead is slideably adjustable within the outer lead and supports a ventricular electrode. The outer lead supports an atrial electrode.  A connector at the other end of the leads supports and secures a connector pin for the outer lead in one sleeve and provides for slideable adjustment of the inner lead which includes a proximal tip in the other sleeve.  An O-ring engages in an O-ring groove in the other sleeve to provide a liquid seal between the atrial coil and the end of the ventricular coil.  The proximal tip and con-nector pin connect to a pulse generator.  The transvenous leads with the closed fixation loop are intended for pacing the ventricular and atrial chambers of a heart.

Abstract: ABSTRACT OF THE DISCLOSURE A self-contained fire protection system can be supplied in kit form and is specifically adapted for installation by a novice in site built or prefabricated housing, such as a mobile home, travel trailer or like building structure.  The system comprises an inlet delivery line which can be suspended beneath the floor of the mobile home and attached to a source of water under pressure with one or more risers extending upwardly from the delivery line through the floor into the interior of the mobile home, and upper branch lines containing automatic sprinkler heads are arranged in series in each branch line and can be attached directly to the risers and inlet line as well.  The delivery line has a dual check valve and water flow indicator or switch, the latter being responsive to opening of any one or more of the sprinkler heads to activate a shunt trip breaker circuit so as to automatically interrupt electrical service to the home including the gas line into the home while activating an alarm circuit.  Compression-type fittings permit sealed inter-connection of relatively lightweight tubing which comprise the delivery line, risers and branch lines and permit ready disassembly of the various lines when the mobile home or trailer is being transported to another site.

Abstract: METHOD FOR RENDERING NON-FERROUS    METALS CORROSION-RESISTANT                          Abstract Non-ferrous metal substrates such as aluminum are coated with a composition consisting essentially of a dispersion of colloidal titania particles in a water/polar organic solvent medium of a partial condensate formed by hydrolyzing a silane such as methyltrimethoxysilane in the presence of the colloidal titania particles and in the presence of a sufficient amount of an acid such as acetic acid to provide a pH in the range of from 2 to 6. Optionally, the composition can contain up to 20 weight percent of colloidal silica and/or up to 5 weight percent of other types of monoorganosilsesquioxanes based upon the total weight of solids in the composition.  The coated substrates are heated until the coating cures, preferably at 50°C to 150°C, to form a transparent coating which renders the substrate more resistant to corrosion induced by acids or salts such as road salt or ocean spray.

Abstract: PHN. 9736            49 ABSTRACT:           A multi-source/receiver data processing system comprising a communication bus which consists of at least one transfer medium.  Clock signal generators have diffe-rent tolerances with respect to each other.  In order to prevent sources and/or receivers having a slow clock sig-nal generator from being excluded as rightful participants from an action concerning a communication, there are pro-vided means whereby it can be determined whether said bus is "ready" for executing said action.  The means comprise first and second detecting means whereby it can be deter-mined that the communication bus is "ready" during a first and a second period of time, respectively.  When an active participant determines that this second period of time has expired, the bus is indeed ready for this active partici-pant and all further active participant which have mean-while determined during their first period of time that the bus is ready, so the bus can be occupied by this action. A data source and/or data receiver may be a programmed digital signal processor.

Abstract: ABSTRACT OF THE DISCLOSURE           The phase of an output subcarrier signal may be varied over a range of 360° with respect to the phase of an input subcarrier signal.  A ramp generator which generates a ramp at one-half the subcarrier frequency, is coupled to a very fast differential comparator means whose output causes a subsequent tuned circuit to ring at the subcarrier frequency.  Continuous oscillations, recycled every second subcarrier cycle, are generated as determined by the threshold set on the differential comparator means.          A crystal filter reproduces the output subcarrier as a clean sinewave.  Remotely controlled phase adjustment of from zero to 360° is provided by varying the threshold of the differential comparator.
