Abstract: A detector (100) determines whether an input signal (10) comprises a first signal or a second signal. A first local signal (207) is generated based on the first signal and a second local signal (307) is generated based on the second signal. A first error (211) is formed based on the first local signal and a scaled input signal (50), and a second error (311) is formed based on the second local signal and the scaled input signal. A first distance (215) between the scaled input signal and the first local signal is formed based on the first error, while a second distance (315) between the scaled input signal and the second local signal is formed based on the second error. Whether the input signal comprises the first signal or the second signal is determined by comparing (60) the first distance to the second distance.

Abstract: A formable composite magnetic flux concentrator material is composed of about 65% to 90% ferromagnetic material, such as iron powder, and about 35% to 10% binder, the binder being a mixture of an epoxy and one or more catalysts. The concentrator material is provided in a formable state as a putty-like body which can be worked into any desired shape dictated by the configuration of the induction heating coil used in a particular application. In one form, the density of the concentrator material is increased by application of vibration, compression and vacuum to de-air the material and to reduce voids therein. In another form, the iron powder comprises spherical-shaped particles and non-spherical shaped powders chosen in a ratio to maximize the density of material available.

Abstract: A sewer line multiple trap priming system comprises a house line and a plurality of branch lines all communicating with each other and supplied with water under pressure. A plurality of makeup priming water lines are connected, one to each of the traps. In all but one of the branch lines pressure sensitive valves interconnect the branch lines and the makeup priming water lines. Upon a change in pressure in the branch lines by a predetermined increment, these valves are operable, to inject a charge of priming water into the priming water lines and hence into the traps. In said one of the branch lanes, from time to time valve means withdraws water from the communicating branch lines in amount sufficient to exceed the pressure change increment and thereby operate the pressure sensitive valves. This insures the transmission of an adequate charge of priming water to the traps at all times.

Two pairs of spaced plates are provided for guiding the handle portion of each carrier of the carrier stock, as reconfigured from the flattened condition into the reconfigured condition, one such pair having an adjustable floor therebetween and guiding the handle portion thereof so that the carrier stock remains in the reconfigured condition when drawn onto the wheel assembly and the other pair guiding the handle portion thereof so that the carrier stock remains in the reconfigured condition when applied by the wheel assembly.  A rotating wheel has arms for striking a frangible junction between the handle portion of each carrier and the handle portion of the following carrier of the series.

Abstract: This invention relates to a surgical intramedullary mail (10), for stabilisation of condylar and supracondylar fractures of the femur. It incorporates a Cruciate arrangement of two obliquely crossing locking bolts (21 and 26) such that each condyle of the femur is gripped by an individual bolt. By this means both femoral condyles are stabilised with respect to the shaft of the femur. The bolts are oriented so that each passes through the main extra-articular mass of each condyle, Further predrilled holes are provided (30, 35) for insertion of proximal locking bolts to stabilise the nail with respect to the shaft of the femur. The nail is intended for retrograde insertion from distal to proximal into the intramedullary canal of the femur. Insertion of the locking bolts may be facilitated by the use of a temporary jig which is attached securely to the distal end of the nail (11). Nails of similar design can be used for stabilisation of equivalent fractures of the humerus.

Abstract: The invention relates to a method and an apparatus for the biochemical purification of a contaminated liquid medium, in which the liquid medium is passed through granular filter material provided in a holder and in which the granular filter material (12) contained in the holder is set in motion, preferably with the aid of an injected gas such as air. Microorganisms and/or an active water for microorganisms can be added to the holder. The filter material may comprise a mixture of lava and sand, for example 28 % to 38 % sand and 61 % to 71 % lava. The granule size of the sand is 0.3 to 1.2 mm and the granule size of the lava is 2 to 10 mm. The main flow of the medium to be purified and the injected gas are oppositely directed. To set the filter material in motion, use is advantageously made of an inner tube (33) placed in an outer tube (32), gas being, blown through the inner tube under the lower end of the inner tube (31) so that gas and filter material drawn in at the lower end of the tubes and medium are transported upwards through the inner tube.

Title: Method of multi-tone printing
Inventor: PATON ANTHONY DAVID
IPC: H04N1/40
Filed: 1995-10-02
Granted: 2008-04-22
Abstract: A method of multi-tone printing employs a drop-on-demand printing apparatus (100) for depositing ink droplets from an array of channels (104) on printing element areas of a substrate (111) which is movable relatively to said apparatus. The channels' length and nozzle location and dimensions afford each channel with a high longitudinal resonant frequency and electrically actuable means (110, 112, 114, 116, 118) supply energy pulses to a selected band of channels at or near the resonant frequency of the channels to deposit from each selected channel in the corresponding printing element area of the substrate a number of drops equal to the number of pulses applied thereto, the number of pulses applied being dependent on the tone of printing required.  Droplet ejection from even numbered channels is in anti-phase at the resonant frequency with droplet ejection from odd numbered channels.

Abstract: A bit-serial compressor (106) has a pre-divider circuit (208) receiving input serial data and generating a partial numerator. Divider circuit (210) divides the partial numerator by a denominator and generates a partial remainder that is fed back to the pre-divider circuit (208). Divider circuit (210) also generates serial data that is sent to an absolute value circuit (216)and then to a bit-serial filter (218). Bit-serial filter (218) generates an average signal from the serial data. A comparator circuit (224) compares the average signal to a threshold signal and generates the greater of the average signal or the threshold signal for use as a denominator in a next division cycle. The divider circuit includes an overflow control circuit (618) which detects overflow from the carryout bit of the partial remainder operation at the beginning of a division cycle and the sign bit of the numerator. If overflow is detected, the output is clipped according to whether the numerator is positive or negative.

Abstract: An optical transmission system utilizing a nonlinear fiber demultiplexer. A timedivision multiplexed optical signal is transmitted via a first optical signal path. An optical pump pulse is transmitted via a second optical signal path. The optical pump pulses are synchronized to correspond to the pulses in the multiplexed optical signal for which extraction is desired. The first and second optical signal paths are coupled such that the portions of the multiplexed signals which are synchronized with the optical pump pulses are amplified through Raman gain. The resulting signal is detected and passed through a threshold detector which filters out pulses below an intensity threshold. The desired demultiplexed signal, which was amplified by the pump pulses, passes through the optical threshold detector as an electronic pulse.
