Title: Class b amplifiers
IPC: H03F3/30
Filed: 1970-07-20
Abstract: 1313152 Transistor Class B amplifiers MULLARD Ltd 20 July 1970 34974/70 Heading H3T In a Class B amplifier having a driver transistor TR1 and complementary transistor output devices TR2, TR3 serially connected between a direct current supply, a first boot-strap circuit R1, R2, C1, TR2 is connected to the collector of the driver transistor TR1 and through a diode D3 to a second boot-strap circuit R6, R7, C2, TR3 so that if the collector current of the driver transistor TR1 rises above a predetermined level the diode D3 is cut-off to isolate the collector of TR1 from the second boot-strap circuit. The diode D3 protects the driver transistor TR1 from excessive current flow and diodes D1 and D2 protect the output transistors TR2, TR3. The load RL may be a loud-speaker and instead of the load being connected to the centre point of the supply it may be connected to one side of the supply through a capacitor. A voltage level setting arrangement X may be a series chain of diodes or a transistor (TR4, Fig. 3, not shown) and the output transistors TR2 and TR3 may each be replaced by a pair of transistors (TR5, TR6 and TR7, TR8).

Title: Control system for gas turbine engine
IPC: F02C7/262
Filed: 1970-08-11
Abstract: 1340879 Gas turbine control systems DEFENCE SECRETARY OF STATE FOR 5 Aug 1971 [11 Aug 1970] 38622/72 Heading G1N The deceleration of a gas turbine engine is sensed electrically and the signal analysed to determine whether it is due to flame extinction or a controlled demand. If the deceleration is due to flame-out, the fuel supply is controlled independently of the speed demand signal until the deceleration reaches a lower value. Re-ignition is automatically initiated if the speed does not fall below a predetermined value. As shown (Fig.3) a control signal PL normally operates through a governor 16 to produce a signal F controlling valve 12 regulating the fuel flow rate. The signal PL is compared at 26 with a signal N representing the HP compressor speed, and compared at 21 with a signal TP representing the actual position of valve 12. Unit 22 senses the larger error signal to determine the value of signal F. The flame extinction condition is sensed in unit 17, wherein the speed signal N is differentiated by capacitors 37, 38 and modified in accordance with a signal N/T¢, dependent on engine speed N and temperature T, and the error signal on lead 41 from the fuel control loops, to produce a deceleration signal dN/dt which, at a predetermined value, causes a switching amplifier 42 to operate a relay 46 energising the flame igniter. The signal N/T will inhibit switching amplifier 42 if the engine speed is below a predetermined value.

Title: Discriminating apparatus for moving translucent sheets
Inventor: PETTET R S
IPC: B65H7/14
Filed: 1971-05-28
Abstract: 1344986 Counting apparatus DE LA RUE INSTRUMENTS Ltd 28 May 1971 [4 June 1970] 26940/70 Heading G4D [Also in Division G1] Apparatus for discriminating between moving translucent sheets in respect of their opacity, comprises means for conveying them in spaced relationship between a light source L 1 , Fig. 2, and a photo-cell PE 1  and a pair of differential amplifiers I, II to which the photo-cell output is applied, the differential amplifier I being arranged to produce a positive output signal when the optical attenuation by a sheet exceeds a predetermined level and the amplifier II producing a positive output when a higher level is exceeded. The amplifier outputs may be fed to separate counters, or the arrangement may be incorporated in a machine for counting and examining banknotes in which the length of the note is measured by using the lower level detector to gate mechanically generated clock pulses to a counter, the counter having three outputs which are activated for different note lengths so that folded notes showing extra opacity are rejected, an alarm is given in respect of partially overlapping and abutting notes, and normal and overlapping notes are counted, the former creating an erroneous count which is indicated by a lamp. The normal pulse count is inhibited by long notes of high opacity and actuation of the reject mechanism is permitted only if the length count shows that the leading edge has not passed the point of reject interception. The output from photo-cell PE1, Fig. 2, is applied to differential amplifiers I, II, through a linear amplifier 50 and a pair of R.C. networks in which the capacitors C1 are charged by the photo-cell output during the gaps between sheets, to provide a reference against which the following attenuated sheet signal is compared. The differential amplifiers include positive feedback whereby the output in the absence of a note is a maximum negative. A known banknote feeding transporting and defleeting mechanism is described with reference to Fig. 1 (not shown).

IPC: C04B38/00
Filed: 1998-11-23
Abstract: A method of firing a green cordierite-ceramic honeycomb structural body containing a carbonaceous material, for example, an organic binder, comprising a two phase process. The first phase comprises firing the green honeycomb structural body in a firing atmosphere to a temperature and for a time sufficient to initiate and sufficiently achieve release of the carbonaceous material while introducing into the firing atmosphere a fluorine-free low-oxygen gas comprising less than about 20% O2, by volume. Once the carbonaceous material is sufficiently released, the second phase involves conventionally firing the green body for a time and a temperature sufficient to initiate and sufficiently achieve the conversion of the green ceramic honeycomb structural body into a fired honeycomb body.

Title: Method for providing service and rate negotiation in a mobile communication system
IPC: H04W4/00
Filed: 1995-06-14
Abstract: In a method for negotiating service configuration in a communication system having at least one dedicated channel which is not shared by communication devices in the communication system, a request message indicative of a proposed service configuration is generated in a service negotiator (20). The request message is multiplexed, in a multiplexer (22) coupled to the negotiator (20), with an information data signal to produce a multiplexed signal. The multiplexed signal is encoded in an encoder (24) interposed between the multiplexer (22) and a transmitter (26) in accordance with a service configuration selected by the service negotiator (20). The multiplexed and encoded signal is transmitted by the transmitter (26) over the dedicated channel. Received signals are decoded a decoder (16) interposed between a receiver (14) and a demultiplexer (18). A response message indicative of a response to the proposed service configuration is received by the receiver (14). A determination is made by the service negotiator (20) whether the response message is indicative of a mutually acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal in accordance with the proposed service configuration if the response message is indicative of an acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal with a universal default service configuration if the response message is not indicative of an acceptable service configuration.

Title: Fluid pressure sensing chamber
Filed: 2006-10-23
Abstract: A surgical cassette (200) is provided having a fluid pressure sensing chamber (210) with a tubing extension (240') extending through a void (230') in the chamber. The tubing contains at least one port (260') that fluidly communicate(s) with the pressure sensing chamber, being adapted to allow the purging of air from the chamber during initial priming of the cassette, but being sized so that air bubbles entering the tubing extension cannot easily flow into the chamber. The tubing extension further contains a reduced diameter portion (241) that creates a pressure differential upstream and downstream of a flow restrictor (242). The differential pressure creates flow through the chamber under high liquid flow and turbulent liquid flow events.
