Title: Ship location graphical display - has on-board computer interpreting navigational data to produce position plot on chart
Inventor: BYLINSKIJ LEV V
IPC: G06F19/00
Filed: 1979-08-16
Abstract: The ship navigation system provides a graphical display of position on a navigation chart. The system has inputs from a drift transducer (1) and a compass (2) that are interpreted by an on-board computer (3) to determine the velocity components of the vessel. Outouts are processed by binary multipliers (8,10), coupled to current stages (16,17) supplying drive stages (29,30) on a chart recorder (31). The pen produces a plot of the vessel's position on a navigation chart (53). An approximator (38) provides a correcting reput (39) to a non-linear converter (33) processing trigonometric functions. The produced plot is continuous over the range of the navigational chart.
Patent DE-2937343-A1 (DE)
Inventor: KATHOLNIGG ROLAND ING
IPC: B28B11/16
Filed: 1979-09-14
Abstract: The invention relates to hollow bricks consisting of fired clay and having an uneven number of offset rows (5) which contain large chambers (1), with a rectangular cross-section and a length of at least 70 mm, and part-chambers being essentially half the length of a large chamber (1). In each outermost row (5') of said hollow bricks, at least one end chamber is formed by a part-chamber (2'). The transverse web (6') separating the part-chamber (2') from the adjoining large chamber (1) reinforces the corner region, with the result that the hollow bricks can be extruded without damage. Preferably, part-chambers (2'') of the third to (n - 2)th row (5'') are open towards the abutting surfaces of the hollow brick (20), with the result that the heat-flow path through the brick grid also approximately corresponds, in the butt-joint region, to that in the central region. Horizontal extrusion is permitted by the simultaneous extrusion of a transportation sub-layer which consists of clay and on which the green bricks cut from the extrudate remain, at least until they achieve an inherent strength which permits further, problem-free handling. <IMAGE>

Title: Internally insulated hot gas duct for fast flows - has insulation cover plates fixed by sleeved bolts to duct wall
Inventor: SCHOENING JOSEF DIPL ING
IPC: G21C11/08
Filed: 1979-11-14
Abstract: Thermally insulated gas duct of large dimensions is intended for conducting high temp gas at high speed and comprises a support structure on the cold (outer)side, cover plates on the hot(inner) side and insulation between these outer and inner sides. The hot cover plates are connected to the cold support structure by through bolts passing completely through the insulation; each bolt has a spacer sleeve bearing against the inner face of the outer (cold) duct and terminating at the other end at a short distance from the bolt head to form an annular gap between underside of bolt head and end of spacer sleeve. The hot side cover plates fit into this annular gap. Used for hot gas ducts in high temp reactor systems, process plants and breeder reactors. By using a spacer sleeve, the pull of the bolt clamping the inner cover plates in position is transmitted directly onto the spacer sleeve and through it to the outer support duct, without relying upon comprssion of the insulating material. Thus the inner cover plates are firmly anchored against flutter due to the high speed gas flow without depending upon the resilience and resistance of the insulation.

Title: Gauge for thickness measurement of plated steel - uses ultrasonic probe at surface to produce echo from difference in crystal grain at interface
Inventor: TAKAHASHI SHIZUO
IPC: G01S15/88
Filed: 1980-05-21
Abstract: The method for measuring the thickness of plated steel, uses an ultrasonic test element in contact with the surface of the specimen, which emits an ultrasonic sound wave. The wave travels through the material, and is reflected back to the transducer from the lower internal surface, after which it is displayed on an oscilloscope, the position of the echo indicating the entire thickness of the material, this being proportional to the displayed length. The relationship between the scale and the time axis and the measured thickness can be calibrated, as a probe of known thickness is used, in which the sound velocity is constant. As a result of the difference in the crystal grains at the intersection between the plating material and the base material, an ultrasonic echo is produced, which is amplified and rectified, allowing the strength of the plating over the entire surface to be measured a technique previously considered impossible.

Title: Broadband, reflection-free HF directional coupler - has sec. winding tapping producing matching wave impedance
Inventor: TRIEBS OTTOMAR
IPC: H01F19/04
Filed: 1980-06-12
Abstract: The transfer junction consists of only a single transformer (31) with, e.g. a single primary turn connecting the coaxial input (32) with a first coaxial output (33). A resistor (RE) in series with the sec. windings (W3,W2) links the input (32) to ground. With the tapping point (38) a second coaxial output (37) is connected. The sec. windings pref. have five turns. The tapping point (38) is connected in such a manner as to produce a matching wave impedance for that of the second coaxial cable to be plugged into connector (37). To provide adequate resistance for the LMP (low) frequencies, an improved broad-band performance can be achieved by interposing a resistor between ground and the secondary windings (W2,W3) with a small capacitor in parallel.

Title: Shoe
Inventor: FUKUOKA SADAO
IPC: A43B13/18
Filed: 1981-01-30
Abstract: The invention relates to a shoe with ventilation, in general footwear with ventilation, in which the outsole consists of deformable material and an air chamber is defined between the outsole and the insole. Orifices, through which air circulation is possible between the air chamber and the inside of the shoe, are formed in the insole. Air circulation is brought about in that, as a result of the weight of the shoe wearer, the outsole is deformed and air is thereby conveyed out of the air chamber into the inside of the shoe. When the weight of the shoe wearer no longer acts on the outsole, the outsole is restored to its original shape, with the result that air circulation from the inside of the shoe into the air chamber between the insole and the outsole takes place. <IMAGE>
