Abstract: 1,205,560. Making shaped laminates. BUSHBOARD CO. Ltd. 8 Feb., 1968 [30 Dec., 1966], No. 58264/66. Heading B5N. [Also in Divisions A4 and B6] A supported curvilinear sheet assembly is produced by fixing a sheet to a discontinuous surface presented by a two-part support, bending the sheet along an unsupported region thereof corresponding to the discontinuity in the surface presented by the support, applying a settable material to the curvilinear region of the bent sheet on the same side thereof as the support and allowing the material to set. The assembly may be a vanity unit top having an upstanding back ledge splash back, the horizontal and upright surfaces being veneered with a single sheet of synthetic resin. In Figs. 1 and 2, a piece of chip board 1 is cut along one end region at 2 and recesses 3 formed on its upper surface at each side of the cut. Adhesive is applied over the upper surface by a spreader and a veneer sheet 4 of synthetic resin is placed over its upper surface and the assembly pressed together in a heated press. The assembly was positioned on a table so that the unsupported region 5 was below an electric heater element extending across the table, then removed and the shorter end region 6 placed in a clamp and the larger part 7 lifted so as to bend the sheet 10 until the two parts of the board are at right angles. Resin reinforced plaster 8 is then run in behind the bent region of the sheet and a rigid wooden strip 9, adjacent sides of which are coated with the same resin adhesive employed on the sheet and in the plaster, is forced against the plaster so as to locate it against the cut ends of the chip board.

Abstract: 1357152 Displaying and recording well logging data SCHLUMBERGER INLAND SERVICES Inc 19 April 1971 [2 March 1970] 59270/73 Divided out of 1357151 Heading G4H Apparatus for displaying or recording well logging signals as a function of depth comprises means for producing at least one writing signal from at least one data signal, and means for combining the writing signal with a coding pattern signal so as to produce a coding pattern between boundaries, at least one of which represents said data signal. The different coding patterns indicate the materials in different strata. The data may be stored in a digital tape recorder 21 in n channels of series data or may be received direct from the logging device. Depth information is either recorded or received direct from a displacement encoder engaging the logging device suspension cable. The data signals from 21 are low pass filtered at 22 and pass to modulators 23. The modulated signals are passed to coding circuits 45 and also to area coding card reader 47. The line and area coding signals are combined in circuit 42 and used, along with other signals to modulate the brightness control of CRT 25. A film 36 moved by constant speed motor 37 records the CRT display. Sweep and scale line circuit.-The beam scanning and general synchronization is controlled from sweep circuit 24. The sweep voltage is generated by a digital to analogue converter connected to the output of a clock fed counter. The counter is reset on reaching a predetermined reading. Scale lines are generated by the response of a comparator to predetermined counts. Depth circuits.-The depth is signalled every 10 feet and a pulse occurs every ¢ft. The initial depth of recording is set on switches 61 (measurements are made upwards so depth decreases) and the determination circuits 60 generate a signal every 100 feet which is displayed on CRT 67 for recording on the film 36. Depth interval generator supplies signals at 2 feet intervals to circuit 42 for producing depth lines on the recording, the lines at 10 and 50 feet being thicker. Pulse position and width modulators.-These allow for rate of change of signal, a signal during a high rate of change being generated as lines on the CRT screen so that the trace does not appear discontinuous. The input signal and a delayed signal are compared with the sweep waveform and the time difference between equality is used to determine the length of the output signal. Line coding circuits.-These operate under instructions from card reader 46 to produce the information trace on the recording medium as a dotted, dashed, long dashed or solid line. Area coding.-The area coding card reader selects signal channels and patterns which indicate particular strata. The patterns are generated in the area between the channel traces when the traces have predetermined relationships. To maintain a constant recording level, the tube brightness is controlled by monitoring a portion of the trace which should have constant intensity.
