Abstract: The two talking wires of a line loop extending from a subscriber station to a central office, provided with respective blocking capacitors, are connected on the subscriber side of these blocking capacitors to respective signal detectors fed from a common battery and cross-coupled by a common compensating capacitor. The two signal detectors receive outgoing signals from the central-office equipment via a common photoelectric coupler and transmit incoming signals to that equipment by way of respective bistable threshold comparators and individal photoelectric couplers. The two signal detectors with their threshold comparators are constituted in integrated circuity by mutually complementary transistors and diodes together with associated resistors.

Abstract: Emulsion-type explosives having improved storage stability are formed by combining an aqueous solution of an inorganic oxidizing salt and an oil in the liquid phase with agitation in the presence of a fatty acid, e.g., oleic or stearic acid, and an ammonium or alkali metal hydroxide, and incorporating dispersed gas bubbles or voids in the resulting water-in-oil emulsion. An emulsifying system including a fatty acid salt is formed in situ. The product contains the fatty acid salt, fatty acid, and hydroxide in a stabilizing equilibrium which permits the product to retain its explosive properties after storage at temperatures as high as 49.degree.

Abstract: A gland body is coupled at its proximal end to a supporting housing by means of a union. A first packing chamber, for a static shutdown packing, is formed at the proximal end of the gland body, with a wedge ring forming the base of the chamber. The wedge ring has a beveled surface diverging outwardly from the base; and a packing body has a complementary beveled surface confronting the wedge ring. A mandrel having a reduced diameter proximal end is received within the gland body for urging the first packing toward the wedge ring. A second packing chamber is formed at the distal end of the gland body confronting the mandrel; and a packing cap threaded onto the distal end of the body compresses the second packing body to seal the mandrel and gland body. The distal end of the mandrel is enlarged to form a third packing chamber confronting the shaft for receiving a third packing body being a dynamic packing for the reciprocating shaft.

Further ingredients such as a cellulose ester and alkali or alkaline earth metal carbonate may be incorporated to facilitate ignition of the composition and increase its combustion time.

Abstract: Movement of an object (intruder) in a specified area is sensed by transmitting microwave energy from an antenna (10) that also receives energy reflected from the intruder, where the received energy is quadrature processed using Doppler techniques. Connected to the antenna (10) is a transceiver (12) that includes a quadrature mixer (48) coupled to an RF oscillator (50) through an RF switch (52). The RF switch (52) is controlled by a switch driver (54) to provide pulse energy from the antenna (10). Doppler outputs E.sub.1 and E.sub.2 from transceiver (12) are processed in the same manner except for a 90-degree phase lead applied to the Doppler output E.sub.2 by a phase lead network (18). Doppler outputs E.sub.1 and E.sub.2 (E.sub.2 90-degree phase shifted) are applied simultaneously to a sum and signature processor (24) and to a difference and signature processor (22). The sum and signature processor provides the "approach" receiving signal and processes the signature to further reduce the nuisance alarm rates.

Abstract: A dry release transfer is disclosed in which the design layer is formed by printing one or more inks onto a carrier sheet, at least one of the inks being a photopolymerizable composition, and subjecting the design layer to ultra-violet radiation or an electron beam discharge in order to polymerize the photopolymerizable ink. By suitable selection of polymerizable components of the ink so that the photopolymerized ink has a high Young's modulus, a stress-resisting design layer is produced which will release readily from the carrier on mechanically stressing the carrier, e.g. by rubbing lightly with a ball-point pen.

Abstract: Breakerless capacitor discharge ignition system for internal combustion engines in which a charge coil and ignition coil are disposed on ferromagnetic core. A changing flux is established by rotation of permanent magnets past the core. The charge coil is connected to charge a capacitor in circuit with a silicon controlled rectifier (SCR) for discharging the capacitor through the primary winding of an ignition transformer. The charge coil and transformer are wound on the core such that voltages of opposite polarity are simultaneously induced therein by the changing magnetic flux. A half way voltage of one polarity charges the capacitor and a voltage of opposite polarity induced in the secondary winding by the changing magnetic flux triggers the SCR to its conductive state discharging voltage stored on said capacitor through the primary winding of the ignition coil.

Abstract: The method described is useful in field flow fractionation techniques for reducing separation times and improving the convenience and accuracy of measuring sizes or molecular weights of particulates. In field flow fractionation, the particulates (particles or macromolecules) are subjected to a force field and a mobile phase while passing through a flow channel. This field strength is decreased exponentially as a function of time. Alternatively the flow velocity is increased exponentially as a function of time. The initiation of the change in field strength or flow velocity may be delayed a period of time. If this time delay is made equal to the time constant of the exponential decay, the range of particulate retention time that is linearly related to the logarithm of the particle size or molecular weight is increased.An apparatus for implementing the method is also described and teaches the use of a function generator for providing the desired exponential decay and delay time.
