Title: Passive object ranging and sizing
Inventor: RAWLINGS KEITH CHARLES
IPC: G01S11/12
Filed: 1991-03-18
Abstract: Apparatus for processing the image seen by a television camera 1 viewing the surroundings of an aircraft has a store 70 of topographical mapping information and object data stores 73, 74 and 75 which contain information about the appearance, location and size of objects in the area to be viewed. The apparatus derives information as to the location of an object in the field of view and determines where the line of sight of the object from the camera 1 intercepts the stored topographical mapping. The range of an identified object is determined trignometrically from its location relative to a corresponding part of the stored topographical mapping and the position of the aircraft. New objects are indicated when they are not present in the object data stores 73, 74 and 75. An indication of the size of the object is determined from knowledge of its range and the angle subtended, and compared with the stored size for checking purposes. The angle subtended by an identified object is compared with the known size of the object to provide another indication of range. <IMAGE>

IPC: H04N1/419
Filed: 1991-04-04
Abstract: In a one-dimensional MH-coding method for compressing the amount of image data in facsimile machines and image filing systems, unlike in the prior art which attaches an end-of-line code to every line, the present method only attaches an end-of-line code to a plurality of lines equal to a predetermined number of lines. Alternatively, an end-of-line code is attached to only selected lines according to a decision table in which there is established beforehand the line numbers of the lines to which an end-of-line code is to be attached. <IMAGE>

Title: Segmented pipe clamp with double load shoulders
Inventor: ADAMEK FRANK C
IPC: E21B17/08
Filed: 1991-04-08
Abstract: A hub clamp will be used to connect two conduits together in end-to-end relationship. Each conduit has a pair of generally parallel load shoulders that extend around the conduit and are axially spaced from each other. The clamp has two sets of load shoulders, one for engaging each set of load shoulders on each end of the conduit. The clamp is in two halves, and when bolted together, draws the ends of the conduits toward each other. Each load shoulder is separated by a flank. The two flanks of the mating load shoulders are separated by a gap when fully made up. The first load shoulder of each conduit may have multiple angled sections. The lead section is at a greater angle than the load section relative to a plane perpendicular to the longitudinal axis of the conduit. The clamp can be mounted releasably to an upper conduit so that it can slide inward and outward, for vertical conduit applications. <IMAGE>

Title: Push tap conversion unit
Inventor: LAWSON MICHEAL PETER
IPC: F16K21/10
Filed: 1992-10-20
Abstract: A press operated adapter or conversion unit for a tap comprises an insert body (2) having a central bore within which is a piston (4). The piston (4) carries a closure seal (11) which co-operates with a bevelled seat (13). A grub screw (5) located in a partially threaded bore of the piston covers part of a bleed orifice, allowing a restricted flow of water from a chamber (14) above the piston out through a lower bleed orifice. The water enters the top chamber (14), as the piston is pressed downwards, through two vertical orifices (16) and becomes trapped by a diaphragm (6) which acts as a one-way valve to seal the orifices (16) adjustment of the screw (5) determines the time taken for closing of the tap following its release after actuation. <IMAGE>
Patent GB-922754-A (GB)
IPC: C08G64/24
Abstract: 922,754. Polycarbonates. PITTSBURGH PLATE GLASS CO. June 9, 1959 [June 12, 1958; April 2, 1959], No. 19637/59. Class 2(5) In the preparation of polycarbonates by reacting an organic dihydroxy compound with phosgene and/or a bis-haloformate of a diol in the presence of an inorganic alkali, the formation of the polycarbonate is completed in an emulsion comprising a continuous phase of water-immiscible solvent for the polycarbonate having dispersed therein at least 50% by weight of the aqueous phase of the medium in the form of fine droplets as a discontinuous phase. Emulsification, which is normally effected towards the end of the reaction (e.g. when the reaction medium has been phosgenated to an extent between 5 and 17 % stoichiometric excess phosgene), may be brought about (a) by adding a small amount of emulsified medium to the reaction medium, the emulsified material being derived either by violent agitation of a small portion of the reaction medium or from an earlier batch, (b) by isolating and agitating within the reaction medium a small portion thereof, (c) by violently agitating the whole of the reaction medium or (d) by adding aqueous alkali to the reaction medium. After emulsification has been effected, the reaction mixture is gently stirred for some time, the emulsion broken by the addition of dilute hydrochloric acid, the organic phase separated, washed and dried, and the polycarbonate recovered therefrom either by evaporation or by precipitation with hexane. The 'monophenate process' of Specification 922,755 may be used. The organic dihydroxy compounds used are preferably dihydric phenols' (e.g. bis-phenols, dihydroxy benzenes, dihydroxy diphenyls or dihydroxy naphthalenes)- alone or in admixture with dihydric alcohols (e.g. alkane diols, oxy- or thioalkylene glycols, cycloaliphatic glycols, unsaturated glycols or aromatic dihydric alcohols). Examples describe the preparation of polycarbonates by reacting bis-phenol A dissolved in aqueous sodium hydroxide solution with phosgene or with a bichloroformate of bis-phenol A in the presence of methylene chloride.

Title: Process for removal of petroleum contaminants from particulate materials
Inventor: RIPLEY IAN STANLEY
IPC: B09B3/00
Filed: 1993-02-24
Abstract: The removal of petroleum contaminants from particulates involves volatilization and/or extraction of the contaminated particulates 9 suspended in hot gases in a toroidal dynamic bed 1. The hot gases may be hot combustion product gases, optionally containing steam or a solvent for the petroleum contaminants. The process results in solids containing less than 1, preferably less than 0.5 and most preferably less than about 0.1 weight percent of the contaminants. The process allows sufficient petroleum removal so that the solids are suitable for direct dumping in a landfill, assuming that the solids are free of non-petroleum environmental contaminants. <IMAGE>

Title: Viterbi equalizer for radio receiver
Inventor: BORTH DAVID E
IPC: H03M13/23
Filed: 1992-08-14
Abstract: A Viterbi equalizer (366) for decoding a  pi /4 DQPSK modulated signal. Because symbol values of adjacent symbols of a  pi /4 DQPSK signal are offset in phase relative to one another, allowable values of succeeding states of a  pi /4 DQPSK signal are four in number. The signal paths of the Viterbi equalizer are thereby limited in number to four allowable next- states (600) and the Viterbi equalizer (366) is operative to select certain ones of the paths connecting the states at the adjacent time intervals as survivor paths to form maximum likelihood paths thereby. <IMAGE>
