Abstract: 1389826 Sonar simulator ELLIOTT BROS (LONDON) Ltd 15 June 1972 [15 June 1971] 28062/71 Heading H4D A simulation system for training in marine fishing includes a visual display similar to that of the echosounding equipment under test wherein simulated responses for fish are provided to the display by a computer. Digital computer 6 selects the appropriate echo range having computed the ship's "position" from speed and heading signals derived from controls on a mock bridge. Counter 11 is set with this range and a generator 4 activates clock generator 12 of the "transmission" of a pulse. This pulse also sets the echograph 3 pen operating. When counter 11 detects that the required echo time has elapsed, address logic 13 activates store 7 which produces the appropriate type of echo for that "position". Background noise is added to the echo signals which are passed to the echograph to make a record. The form of the record is determined by the type of echo supplied by the data store, e.g. sea-bed different species of fish. The computer may be required to provide an expanded display at a particular depth entered at line 17 and also to simulate control of fishing "nets" and to calculate the simulated catch.

Abstract: 327,410. Sykes, A. F. Oct. 3, 1928. Magnetic instruments; diaphragms. - The dimensions of an electromagnetic transmitter as claimed in Specification 220,420, in so far as they relate to the effective sound-path between the back and the front of the sensitive element, including the external pole, are made small enough to avoid any substantial acoustic interference over the important acoustic range. The construction shown comprises a central magnet-pole 1, of about ¢-inch diameter, screwed into a circular steel yoke 2 and an inverted aluminium U-strip 15, about 2 inches long and <5>/6 inch wide, set in a # inch air-gap surrounded by an external magnet-pole 3, about ¢-inch wide and thick, fixed to the yoke 2 by screws 4, 5. To provide for the magnetizing winding 8, an ebonite flange 9 is secured to the pole 1 by a screw 11, the material of the central pole is covered with insulating tape and a presspahn washer 12 completes what amounts to a bobbin. The magnet structure is mounted on a cast-iron pot 6 which houses the step-up transformer and carries an ebonite block 14 for terminals 13 to which the winding 8 is connected. A thread-guard 20 and two tufts of cotton wool serve to keep the strip 15 in place, the ends of the strip being connected to terminals 16 as shown in Fig. III. and thence to the transformer in the pot 6 by the cable 17. By making the pole 1 conical, e.g. by tapering its upper portion, premature saturation of the root of the pole can be prevented. In such a case the strip 15 becomes a rounded V.

Filed: 1945-10-26
Abstract: 603,655. Moulding concrete buildings in situ; inflatable cores. NEFF, W. Oct. 26, 1945, No. 28363. [Class 20(ii)] Relates to the construction of concrete buildings, and provides improvements on the method disclosed in Specification 554,954. A pneumatic former 10 is of open bottom construction and is secured along its bottom edge to the foundation by steel tapes 21, 22 Fig. 3, so that the foundation closes the open bottom. The lower tape 21, disposed below the overhanging surface 19, anchors the former against upward forces, and the upper tape 22, secured against the shoulder 19, anchors it against sideward spreading forces. The former is inflated through the nipple 14, Fig. 1. or through an air pipe in the foundation, and a thin layer of plastic material characterised by its fast setting qualities and lightness in weight is applied to its outer surface. The weight of the plastic material, which is applied from the top downwards, results in a controlled deformation of the former, Figs. 2 and 3. A removable guard strip 23, of veneer, is wrapped on the outside of the tapes 21', 22, to shield the lower edge of the former from the plastic material. The thin layer of plastic material, when set, provides a load-sustaining preliminary structure 25 on which a layer of insulation 26 and a layer or layers of cement 27 may be applied, thus to produce the final building. The former may be stripped from the inside of the final building or may be left in place for its insulation value. The infiation pressure does not exceed 1 1b. per sq. in., and the former may thus be made from a light-weight fabric such as nylon, yarn, cotton muslin or specially treated paper. In constructing the former the sections 11 are cut from the material and secured together at their edges, the bottom edge being preferably reinforced by a suitable strip 12 and an airproofing coating being applied. Door and window openings may be provided for by frames placed against the former, which are set in position by the initial layer of plastic material. The former can be fabricated to provide structure of other shape than hemispherical.
