Abstract: 1446627 Laminates C SOMMER 13 Dec 1973 [15 Dec 1972 4 May 1973] 57897/73 Heading B5N [Also in Division E1] A wall, beam, pillar or like construction is produced by bonding together in face-to-face relationship a plurality of sheets 1 of thermally insulating, expanded plastics material to form a laminate structure, each sheet having a thickness of 10-25 mm., forming a constructional element by adhering a reinforcing means 4 to at least one of the opposed outer faces of the laminate structure so that the reinforcing means at least partially projects from the face to which it is adhered and assembling a plurality of the constructional elements together by connecting the reinforcing means of contiguous elements to provide a continuous reinforcement, or in the case of a beam or pillar, arranging one or more of the laminate structures to form a core of desired cross-section and adhering reinforcing means 4 to an external surface of the core so that the reinforcing means at least partially projects from the external surface to provide a continuous reinforcement on the external surface, and applying a setting material 6 to embed the reinforcement. Sheets 1 which may be in the same or different materials may be of polyurethane, polystyrene or phenolic foam which may contain a filler, e.g. glass fibres or expanded glass beads, and may be bonded together by mineral cement 3. Reinforcing means 4 may be bonded to the laminate structure with mineral cement 5 and may be a rectangular mesh of wire of undulating form having upper and lower peaks, the lower peaks of which are bonded to the laminate structure. The reinforcing means of adjacent constructional elements may be connected by means of pins or clips or by bending and connecting together laterally projecting portions of the reinforcing means. Hydraulic binder 6 may be applied by spraying. The constructional elements may be in the form of flat panels which may be positioned side by side, end to end or at right angles, or tubular elements the section of which may be semielliptical. The constructional elements may be positioned against an existing wall, the reinforcing means being adhered to the outer faces remote from the wall or to both faces of the laminate structure. Beams or pillars having a hollow core may be fitted with concrete into which reinforcing iron bars or rods are incorporated. Sheets 1 may have mutually opposed faces with complementary embossments which fit into each other and at least one of the outer faces of the laminate structure may be embossed.

Title: Pattern recognition equipment
Inventor: RUBENSTEIN D
IPC: G06K9/68
Filed: 1971-12-15
Abstract: 1326852 Character recognition systems INTERNATIONAL BUSINESS MACHINES CORP 15 Dec 1971 [18 Jan 1971] 58163/71 Heading G4R A system for recognizing a pattern, e.g. a character, includes a scanner which scans a main area of the document bearing the pattern i.e. the area in which a character lies, in order to recognize the pattern. If the pattern is one of a selected set of patterns the scanner is then caused to scan a further area in which there may be a further pattern, e.g. a diacritical mark, in order to recognize the further pattern. The characters are scanned, e.g. by a photosensitive device associated with a cathode-ray tube, the initial scanning being of a main area 270 in which a character lies, Fig. 2B. The resulting signals pass via a pre-processor to a character recognition unit. This outputs a code, corresponding to the character, to a central processing unit and to a unit which determines whether the character lies in one or another of a number of sub-sets of characters. As described there are two subsets, one consisting of A.E.I.O. and U and the other of C. A character in one subset may be associated with one of a number of diacritical marks which lies above the character, e.g. as at 205, and a character in the other subset with a diacritical mark lying below it, e.g. as at 206. When a character in either subset is detected the character recognition unit is disabled and one or the other, according to the subset, of two diacritical mark recognition units is enabled. These units receive the output of the pre-processor. Also, the scanner is controlled, according to the subset, to scan the upper or lower diacritical area 280 associated with the character. The output of the selected diacritical mark recognition unit may be used to modify the character code before it reaches the central processing unit. Instead of scanning a diacritical area immediately after detection of a character belonging to a subset, a row of characters may be scanned, followed by scanning the diacritical areas of those of the characters which belong to a subset. The characters may be handwritten on a document carrying guide lines, Fig. 2A (not shown), indicating the character and diacritical mark areas. Such lines are dotted, so as to appear as noise to the pre-processor, or are printed in an ink which is invisible to the photosensitive device.

Title: Single frequency moisture gauge with logarithmic feedback
IPC: G01N27/22
Filed: 1971-12-21
Abstract: 1382437 Measuring dielectric properties - moisture content INDUSTRIAL NUCLEONICS CORP 21 Dec 1971 [21 Dec 1970(2)] 59521/71 Headings G1N and G1U [Also in Divisions H3 and H4] A property of a dielectric material, e.g. the moisture content of a paper web, is determined by applying a constant frequency A.C. signal (18) to a capacitive probe 28 adjacent the web 34, deriving (38, 44, 50) from the probe a detection signal (52) representative of the moisture content, producing (54) a derived signal logarithmically related to the detection signal, and using the derived signal to control a voltage controller 14 which reduces the magnitude of the A.C. signal (18) applied to the probe as the detection signal (52) increases, thereby reducing the range of signal magnitudes which components in the system have to be capable of handling. The probe 28 is of the fringe field type and forms part of a capacitive potential divider 28, 40 from the tapping of which the detection signal (52) is derived. That component of the detection signal which is due to the intrinsic capacitance of the probe, in the absence of the web, is cancelled out by a balancing capacitor 48 to which is applied a signal 180 degrees out of phase with that applied to the probe. To evaluate the moisture content, a signal (63) logarithmically related to the applied signal (18) is subtracted from the derived signal (55) to produce an output signal (73) which is linearly related to the logarithm of the ratio of the derived to applied signals, and hence proportional to moisture content. The output signal is passed to a recorder, indicator or control system 68 via (i) a subtracter 65 where a bias signal determined by the mass of the paper being tested, is subtracted; (ii) a variable gain stage 66 whose gain is set in accordance with the paper grade; (iii) a filter 67 to give the system a selectable time constant. The voltage controller 14 is temperaturecompensated and is protected against overloading which occurs when the web 34 is absent. Calibration facilities are provided for (i) setting the balancing capacitor 48 (164); (ii) adjusting the magnitude of the output signal (19, 154-162); (iii) adjusting the indicating arrangement 65-68 (168, 170).
