Abstract: In a digital data transmission system for transmitting a serial digital data stream between a first unit (21) and a second unit (30) connected to a first and second bus (22,22'), respectively, a first apparatus (60) interfaces the first bus (22) to a transmission medium (51) and a second apparatus (31) interfaces the second bus (22') to the transmission medium (51). The first and second unit and the first and second apparatus each have their own clock circuit. The first and second apparatus each comprise an encoder (63) which outputs the serial digital data stream onto the transmission medium (51) corresponding to serial data received from the first bus (22) during a transmission period of the first bus. The encoder outputs the serial digital data stream onto the transmission medium in a predetermined format during a quiescent period of the first bus. A phase relationship of the serial data and the serial digital data stream outputted at the start of transmission between the quiescent period and the transmission period is established in a single bit time. A decoder (62) decodes the serial digital data stream inputted from the transmission medium (51) to determine the bit value of information. A receiver/transmitter (61) couples the signals between the first bus and the apparatus.

Abstract: An injection molding thermal gated nozzle (10) having a nose portion (28) which extends forwardly to the cavity. The nozzle has a melt channel (40) which extends through the nose portion (28) to form the gate (42). An integral electric heating element (12) has a forward portion (78) with a generally rectangular cross section and a number of adjacent coils which form an inwardly tapered inner surface (90). Part (92) of the inner surface (92) of the forward portion of the heating element forms an inwardly tapered portion (94) of the melt channel (40) adjacent the gate (42). This direct contact of the heating element (12) with the melt reduces considerably the cycle time of the thermal gate. The forward portion (78) of the heating element (12) is shaped by compressing it between tapered dies (100,102). It is then mounted between forward and rearward portions (108,110) of the nozzle, and the assembly is integrally brazed together in a vacuum furnace.

Abstract: In mobile communication system in which service area is covered with a plurality of location registrations areas (A₁...A₆, B₁...B₆) each having a plurality of cells (X, Y, Z) each relating to a specific base station, each location registration area has a plurality of groups (A i , B i ) so that the cells (X, Y, Z) belonging to any group (A i ) overlaps partly with the cells (X, Y, Z) of other groups (B i ), but do not completely coincide with cells of other groups, and each mobile station belongs to one of said groups. When a mobile station moves beyond border of location registration areas, the location updating for the mobile station is carried out at the cell which the mobile station stays. In that case, as the mobile stations are classified into a plurality of groups, the traffic in each cell for location updating is dispersed to many cells, and the maximum traffic density for location updating per cell is reduced. So, the number of control channels in the system for location updating may be reduced.

Abstract: An adaptive sequence decoder comprises a maximum likelihood sequence estimator for deriving a decision sequence of a received signal in response to a control signal. Channel estimators of zero-th to m-th order of channel impulse response are connected to the MLSE to produce a first signal representing a respective order of a replica of transmitted signal and a second signal representing a respective order of channel impulse response. The first signals from the channel estimators are summed to produce the replica of the transmitted signal for comparison with the received sequence to produce an error signal, and the second signals are summed to produce the control signal. At periodic intervals, the MLSE control signal is initialized and the zero-th order channel estimator is reset to the initialized control signal, and the other channel estimators are reset to respective initial values to prevent time dispersion.

Abstract: A sensor for detecting the level of flowable media is described which consists of a floating magnet and a chain of switching elements which is sensitive to magnetic fields. The chain of switching elements contains a multiplicity of switching units which are arranged in plastic housings (4') which, for their part, are mounted on a strip-shaped carrier and connected to one another electrically; each switching unit consists of a reed switch and at least one resistor. The chain of switching devices is constructed in such a way that it can be produced directly from a single starting strip, without it being necessary to mount initially obtained separate switching units on a carrier strip. This is possible owing to the following features of the chain of switching elements:   - the plastic housings (4') are joined to one another mechanically at mutually opposite sides by metallic conductors (5) forming a chain; - the same metallic conductors (5) also connect the switching units to one another electrically; - located on one side of the plastic housing is a metallic carrier strip (5), which reaches uninterrupted over the entire chain and from which electrical crimp connections (12) respectively lead to a terminal of each reed switch; - located on the opposite sides of the plastic housings (4') are metallic switching bridges (11) which connect the second terminal of each reed switch to a terminal of the resistor belonging to the same switching unit and connect both to the other terminal of the following resistor in the chain.   <IMAGE>

Abstract: The frequency and mark/space ratio of call progress tones can greatly deviate from the guide lines of the postal administrations, particularly in private branch exchanges. As a result, it is difficult to avoid malfunctions when connecting the subscriber terminals to a communications network. To enable even an untrained user to connect the subscriber terminal to an existing communications system, a device for learning call progress tones is provided in the subscriber terminal according to the invention. For this purpose, the subscriber terminal contains a control which calls up the call progress tones from the communications system and determines their mark/space ratio which is stored in a memory. If the subscriber terminal is connected to a private branch exchange, both the call progress tones of the extension and those outside the extension can be learned. The device can be used in any subscriber terminal which must respond to call progress tones. <IMAGE>

Abstract: A coupler 10 consists of a length of cross-linked polyethylene pipe having a spiral groove 16 cut in its outer surface and another spiral groove cut in its inner surface. A heating element 18 is wound in the groove. The coupler is expanded mechanically so as to have an easy fit over the ends of polyethylene pipes 12, 14. The heater element 18 is energized and the coupler shrinks and forms fusion welded joints between itself and the pipes. No preparation of the pipe ends is necessary because the serrated inner surface cuts through the oxidised skin and bonds to material beneath the skin. The coupler is especially advantageous in large sizes of 500 mm or above. Instead of an electric heater, radiant energy, eg infra red or light is used to heat the coupler. For example, an array of reflector lamps can be used circumferentially located around the coupler.

Abstract: A voltage controlled reference oscillator (20) with a high Q and narrow tunability bandwidth produces an output oscillator frequency which is frequency divided (18) by four alternative constants to produce four different clock frequencies for four different digital video standards, D1 component at 270 MHz, NTSC D2 composite at 143 MHz, PAL D2 composite at 177 MHz, and a proposed new composite video standard that is to operate at a 360 MHz clock rate. Automatic identification of which serial digital video is present is accomplished by having the clock generator (20,18) produce a clock signal at the frequency required by one of the video formats while a phase lock loop (90,26) attempts to lock onto the incoming signals at that frequency. If no lock occurs within a predetermined time interval, the clock generator (20,18) is made to produce a clock signal at the frequency required by a different one of the video formats and the phase lock (90,26) is attempted again. This is repeated until a lock is attained. Optionally, when a lock occurs, the video is tested (80) for validity within the format that is consistent with the clock frequency that produced the lock.

Abstract: A gas turbine engine (10) has a core frame separable from a vane frame for removably attaching the vane frame to a core structure through a mid ring (50). The mid ring includes an annular forward panel and an annular aft panel, each of which has a radially outer flange and a radially inner flange. The inner flanges are welded to the core frame and the outer flanges are bolted to the vane frame. A plurality of circumferentially spaced stiffeners (138,140) extend between the forward and aft panels, with each of the stiffeners including a pair of stringers extending diagonally across the stiffeners. Panels may be incorporated with the stringers between the triangular shaped areas adjacent the forward and aft panels of the stiffener. The bolted connection between the mid ring (50) and the vane frame includes a plurality of tongue and groove joints formed in the flanges of the mid ring and vane frame. The tongue and groove joints provide additional radial support for the core engine within the vane frame. Preferably, the tongue and groove joints are formed with angular sides so that conformance between the joints can be achieved by simply tightening the bolts attaching the joints. In one embodiment, the tongue and groove joints may only be used at preselected circumferential positions with the remainder of the flange connections using overlapping lap joints.

Abstract: A technique for increasing the efficiency of a system such as an artifical intelligence system or a data base system in which a query (Q) is applied to a set of formulas (URF). The technique creates an approximation (AF) of the set of formulas which is computationally more tractable than the original set. The original set is used to answer the query (627) only if the approximation fails to provide the answer (622). The approximation is made by a compilation process (613) which provides a series of ever- closer approximations. A given query is answered using the currently-closest approximation (623). The approximation may consist of a first set of formulas which is an upper bound (i.e. implied by) of the original set, and a second set which is a lower bound (i.e. implies) of the original set. In this case, the compilation process produces a series of increasing lower bounds and decreasing upper bounds until a greatest lower bound and a least upper bound are reached. Example applications of the technique are given for propositional languages, first order languages, lauguages based on definite clauses, and frame languages.

Abstract: A method and apparatus provide for the personalization of magazines and like "book" publications. A book (43), having a cover (44) which provides address information (45), is formed from a number of signatures (25). This is accomplished by automatically printing at least one personalized signature with variable personalized printing (20, 21, 22) (such as by ion deposition), assembling the personalized signature with at least one other signature, detecting the personalized printing on the personalized signature (as by optically scanning OCR characters), and in response to such detecting, printing address information on the cover. The personalized printing can be the addressee's name, photograph, or identification number. The personalized signature may be assembled with other business documents (47), such as a business reply envelope, and may be perfed to provide a return form (27). Alternatively, complete address information may be printed on the signature and die cut window (48) formed in the cover, through which the address information is visible once the book is assembled. All of the books having address information with common postal codes are produced in a sequence -- regardless of the demographic form of the signature that has been personalized -- so as to maximize the chances for securing a minimum postal rate.
