Title: Free-running oscillatory power supply circuit
Inventor: BERNHARD WERNER
IPC: H03K3/30
Filed: 1993-10-29
Abstract: ABSTRACT OF THE DISCLOSURE. To minimize circuit components of a free-running oscillatory electrical energy supply circuit, especially for fluorescent lamps, having a transistor (T1) coupled to a control winding (RK1), and ensure, simultaneously, starting due to spurious or noise signals arising in the circuit upon first being connected or energized, while additionally ensuring rapid carrier depletion of the transistor upon turn-OFF thereof, a first and second diode (D1, D2) having their anodes connected to a common junction (J1), is coupled to the control winding (RK1), the first diode (D1) being connected to a second junction (J2) of a resistor (R) and to the collector of the transistor (T1); a third junction (J3) connects the cathode of the first diode (D1) to the second terminal of the resistor (R), and to the base of the transistor.  A capacitor (C) is coupled in parallel to the second diode, that is, across the junctions (J1, J3).  The capacity value of the capacitor can be reduced from about 100 nF to 10 nF by connecting a third diode (D3)in parallel with the capacitor (C), but polarized oppositely with respect to the second diode (D2).  A free-wheeling or bypass diode (DF) can be connected across the collector-emitter of the transistor; an inexpensive similar effect can be obtained by a much lower breakdown-voltage diode (D4) connected in series with the first diode (D1) and, directly or indirectly, to either the base or emitter of the transistor providing a bypass path through the fourth and first diodes (D4, D1).  Damping impedances, base impedances and emitter impedances can be used, as desired.

Inventor: SPENCER DUDLEY W C
IPC: B29C65/78
Filed: 1994-02-03
Abstract: A sterile containment welding device for plastic tubes comprises a pair of side by side spaced tube holders. Each of the tube holders includes a clamp base and a clamp lid. A pocket is provided in each clamp base extending completely across the clamp base so that a plastic tube could be inserted into the pocket and clamped in the holder when its clamp lid is moved to a closed position. Pockets of the side by side tube holders are alignable with each other to permit a plastic tube in one of the holders to be welded to the plastic tube in the other of the holders. A tube locating member is movably mounted at the end of each pocket in the space between the holders. The tube locating member has a wall disposed in the space beyond the pocket for positioning its plastic tube in the proper position for the later welding step when its tube is moved into contact with the walls. An inactivating member is mounted to each clamp lid to contact the tube locating member and move it out of contact with its plastic tube upon the closing of the lid so that the tubes are exposed to be heated and welded together.

Title: Circuit breaker responsive to repeated in-rush currents produced by a sputtering arc fault
Inventor: MACKENZIE RAYMOND WARREN
IPC: H02H1/04
Filed: 1994-02-25
Abstract: Abstract of the Disclosure A circuit breaker responds to sputtering arc faults by counting the times that a bandwidth limited di/dt signal exceeds a threshold magnitude within a selected time internal In the exemplary circuit breaker, if the threshold is exceeded twice within a one second interval, a trip solenoid is energized. The di/dt sensor can share a sensing coil with a ground fault detector. Alternatively, the resistance of the neutral lead within the circuit breaker is utilized to sense current which is converted to a bandwidth limited di/dt signal for level detection and counting of sputtering arc events.

Title: A Method for Decomposition of Hydrocarbons
Inventor: LYNUM STEINAR
IPC: C01B3/24
Filed: 1992-12-11
Abstract: In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.

Title: Telecommunications
Inventor: CARNALL MURAT A
IPC: H04M1/724
Filed: 1993-12-15
Abstract: The figure shows generally (at 10) a telephone having a speaker (11), a microphone (12), processing means (13), a control unit (14) and an audible indicator (15). When the telephone (10) is used to conventionally communicate with another telephone (not shown), for example to enable respective users of the telephone to speak to each other, electronic signals corresponding to the speech are input to and output from the telephone (10) at input (16) and output (17) respectively. The input (16) and output (17) are connected to a radio transmitter/receiver in the case of a mobile or portable telephone or may be connected to a telephone line cable in the case of a conventional telephone. The processing means (13) electronically processes the signals and in the case of incoming calls these are relayed from the input (16) to the speaker (11).  In the case of outgoing signals these are relayed from the microphone (12) to the output (17). The control unit (14) identifies the presence of a command signal with the incoming calls. If a user of another telephone (not shown) wishes to call telephone (10), the telephone number of telephone (10) is dialled in the conventional way. However if during a time interval of a predetermined length beginning immediately after the number of telephone (10) is dialled the caller inputs a command code via his conventional telephone key-pad, this sends a command signal to telephone (10) which is identified by a control unit (14). Upon identification of the command signal the control unit (14) inhibits the operation of the audible indicator (15) by means of inhibit unit (14b) so that no indication is made of the incoming call. Additionally the control unit (14) automatically establishes the channel of communications as though the user had answered the call.
