Abstract: 1. Circuit arrangement for limiting, regulating and in some cases interrupting the collector current (Ic ) of the switching transistor (T) in the primary circuit, using a current probe (SF) connected in series to the switching transistor (T) and a control component containing a first comparator (V1) and a pulse-duration modulator (PDM), which control component influences the duty ratio of the switching transistor (T) as a function of a comparison value gained from the output signal of the current probe (SF) and a reference signal (UREF1 ), characterized in that the output of the current probe (SF) is connected to the first input of a second comparator (V2), the second input of which is fed with a reference signal (UREF2 ) which is higher in relation to the reference signal (UREF2 ) which is higher in relation to the reference signal (UREF1 ) of the control component (RBS), in that the output of the second comparator (V2) is connected to the set input (S) of a bistable flip flop (KS) and in that the output of the bistabile flip flop (KS) is fed to the input of a switch-off device connected upstream of the pulse-duration modulator (PDM).

Abstract: Apparatus for safe delivery of a beneficial agent to a patient comprising a chamber (98) for the agent through which a fluid passes to the patient and means for controlling the rate of delivery in two alternative modes. In the first mode fluid flow through the chamber is high enough to provide delivery of the agent at a rate independent of the actual fluid flow rate to provide a therapeutic dose of the agent in approximately thirty minutes. In the second mode, the fluid flow rate in the chamber is low enough for rate delivery of the agent to be at least partially dependent on fluid flow rate through the chamber. The control means ensures that a toxic concentration is not delivered to the patient nor develops in the patient's bloodstream. The control means may take various forms.

Abstract: A solid fuel briquette is constructed from a mixture of anthracite duff and petroleum coke held together by bitumen or some other hydrocarbon based binder, the mixture having been pressed to form the solid fuel briquette. The final product can incorporate the constituents in the ratios of 10% to 60% of petroleum coke, 1% to 10% of the binder, with the balance being anthracite duff, all proportions being by weight. A preferred non-smokeless fuel briquette is formed from about 25% petroleum coke, 7% bitumen binder and 68% anthracite duff, by weight. A smokeless fuel briquette may be formed from about 25% petroleum coke, 5% bitumen binder and 70% anthracite duff, subsequently oxidised to reduce the binder content to about 1%.

Abstract: The field rate of a video input signal (V BB ) is doubled by storing each field in a memory (240) and recovering each stored field twice so as to repeat each field and thus reduce flicker. To ensure that even fields overlay even fields, odd fields overlay odd fields, and that all pairs of even and odd fields are interlaced, a timing unit (70) provides a double field rate read control signal (2V) to the memory (240) having a waveform that repeats on a two-field basis and supplies a double field rate vertical control signal to a vertical deflection generator (64) having a waveform that is phase modulated and that repeats on a four-field basis. The vertical deflection generator (64) has a constant retrace time and employs DC coupling, thereby avoiding raster shift which otherwise could occur as a result of the phase modulation.

Abstract: An inflatable well bore packer element (10), having inner and outer elastomer plies (23, 24) and an intermediate sheath of reinforcing wires (26,30) is secured at each end to a central mandrel (18) by inner and outer annular coupling members (32, 35). Wedge-shaped gripping members (42, 43) that hold the free ends of the reinforcing wires between facing surfaces of the coupling members are positioned and secured by independently tightened rings (46, 48). The inner elastomer ply (23) is bonded to the inside of the inner coupling member (32), and the tip of the inner coupling member is formed with a deformable skirt portion (34) that flexes during packer inflation to oppose extrusion of the inner ply into the reinforcing wire holding area between the facing surfaces.

Abstract: In an arrangement for decoding signals which are received in addition to other signals as a modulation of radio waves and whose respective frequency constitutes a specific item of information, a time basis signal of constant frequency is generated from which a reference signal with a controllable frequency position and phase position is derived with the aid of a microprocessor. An output signal is derived if there is a coincidence of the reference signal with the received signal with respect to phase and frequency. The time basis signal can preferably be derived from the instruction frequency of the microprocessor by running through program loops of identical length at least in the timing means. A register which is incremented by changeable values serves for deriving the reference frequency. In the case of two superimposed signals, the one is evaluated with respect to frequency and the other with respect to the pulse duty factor of a binary signal. <IMAGE>

Abstract: A foam extrusion system and method employs a horizontal vacuum chamber (10) with a bulkhead (11) and extrusion die (16) at one end of the chamber, the extrusion die being inside the chamber when the bulkhead is closed. A liquid baffle, preferably water, is provided at the opposite end of the chamber through which the extrudate passes from the chamber to atmosphere. The baffle comprises a pond (30) of liquid having a higher level in the chamber and a lower level (31) outside the chamber. The higher level of the pond is formed between a dam plate (20) and a seal plate (12), the latter forming the opposite end of the chamber. The seal plate includes a size adjustable window (34) through which the extrudate passes, the extrudate being guided by a conveyor (43) to extend inclined downwardly into the pond and to exit through the seal plate and pond with a large radius upwardly curved section. The level of liquid in the chamber is controlled by circulating liquid (50, 51) from the higher level of the pond within the chamber to the lower level of the pond outside the chamber with the amount of liquid circulated being inversely proportional to the absolute pressure in the vacuum chamber. Optionally the circulated liquid may pass through a cooler (61) to control the liquid temperature. The size adjustment of the window or exit orifice in the seal plate may be used to control the flow of liquid from the lower level pond portion outside the chamber to the higher level pond portion inside the chamber, particularly during start up.

Abstract: A communication data system is designed for resiliency by automatically replacing or bypassing defective units. The system includes a number of input/output terminals which are connected to MODEMs through a relay bank. The MODEMs send serial data to a serial I/O module which converts the serial data to bytes which it places on a VMEbus. A network processor sends the data from the VMEbus to a general purpose computer which places the data into the communications network. A general purpose computer or a back-up general purpose computer may detect a defective communication link and automatically switch to a back-up network computer, or cause a control module to switch the relay module to a spare MODEM and spare SIO. The control module may also generate a remote line test to the link between the MODEM and the terminal to determine if that link is defective.
