Abstract: T&B 850 ABSTRACT OF THE DISCLOSURE           A plurality of projections each including a pair of outwardly extending teeth are provided on first and second arm portions of an elongate plate member bendable about an electrical conductor.  The projections on each arm portion preferably extend transversely across the plate member and are substantially parallel to each other and orthogonal to the bending line.  The projections on one arm portion are formed to be transversely offset with the projections on the other arm portion such that upon bending said member so that the teeth contact the conductor, a tooth edge of each of the projections on one arm portion lies between the teeth edges of the projections on the facing associated projections. Piercing of electrical insulation and conductors of flat cable conductors for good mechanical and electrical contact and desirably thin connections is facilitated by such a connector.

Abstract: COOLING LIQUID TEMPERATURE CONTROL SYSTEM              FOR INTERNAL COMBUSTION ENGINE            ABSTRACT OF THE DISCLOSURE           A cooling liquid temperature control system for an internal combustion engine cooled by a cooling liquid which in turn is cooled by a heat exchanger, wherein a primary bypass opened and closed by a low operating temperature thermostat valve and a secondary bypass opened and closed by a control valve are branched from a cooling liquid outlet passage connect-ed between an engine jacket and the heat exchanger.  The control valve can be opened depending on the degree of the opening of the throttle valve.  The secondary bypass is branched from the cooling liquid outlet passage.  The two passages are respectively opened and closed by a high operating temperature thermostat valve .  The secondary bypass is communicated with the primary bypass and the other passage communicated with the heat exchanger.       During normal engine operation with small throttle opening, the cooling liquid flows from the secondary bypass to the primary bypass through one passage, to be returned to the engine jacket while being kept at high temperature.  At large throttle opening range, the cooling liquid flows to the heat exchanger through the other passage while the secondary bypass is closed, and has its temperature reduced before being returned to the engine jacket.

Abstract: IMPROVED IGNITION METHOD AND SYSTEM FOR INTERNAL BURNER TYPE ULTRA-HIGH VELOCITY           FLAME JET APPARATUS                         Abstract An elongated casing forming an air cooled combus-tion chamber includes a venturi type jet nozzle at one end and an ignition system spark plug at its opposite end in axial alignment with the nozzle bore.  The spark plug in-cludes a first electrode separated from a second electrode by an annular space.  A gas having an oxygen content in excess of that of natural air is introduced to the annular space to improve ignition and internal burner start up.          Liquid fuel flow is introduced into the region of extended spark within the combustion chamber and downstream of the ends of the first and second electrodes.  Compressed air, after initial cooling of the combustion chamber wall and nozzle, enters the end of the combustion chamber housing the spark plug to create with the fuel a combustible mixture.  Some of the compressed air is fed to the annular space between first and second electrodes to maintain the extended spark and improved ignition of the fuel/air mixture.

Abstract: ABSTRACT OF THE DISCLOSURE     A two-wire ballast arrangement for fluorescent lamp dimming is disclosed in which a modified transformer utilizing the natural leakage inductance associated with ballast transformers is used to achieve full-range fluo-rescent tube dimming at substantially constant filament heating voltage.  Additional auxiliary secondary windings are disposed in predetermined spaced relationship to the primary winding and the main secondary winding to create a "tapping" effect in the magnetic flux.  The mutual leakage inductances of the auxiliary secondaries in relation to the primary and the main secondary is utilized in a manner such that as the voltage is decreased to the primary, the voltage of the auxiliary secondary windings remains substantially constant to hold the filament heating voltage substantially constant.  Embodiments are disclosed for use either with conventional 50/60Hz or at high frequency, i.e. above 400Hz.

Abstract: DEMULTIPLEXER CIRCUIT            Abstract A demultiplexer circuit which extracts from an incoming time division multiplexed digital bit stream any combination of PCM encoded words (in separate channels), or data bits irrespective of the rate of the latter or the position of the data bits in a given channel.  The demultiplexer circuit includes a random access memory (RAM) for storing information as to the channel(s) to be demultiplexed out of the incoming digital bit stream.  A counter operates in synchronism with the received bit stream and the output thereof serves to access the RAM to provide output signals indicative of the channel(s) carrying information for the subscriber station.  These output signals are utilized to read the digital signals intended for said station into a shift register.  A summing circuit is interconnected with the register so that conference calls are summed in real time.  Before the next frame of digital signals, the contents of the register are transferred to a second shift register.  The digital signals are then read out of the second register at a steady rate, with a stored data signal being similarly outputted irrespective of the rate of the same or its position in a given channel.
