Patent EP-0328360-A3 (EP)
IPC: G01S7/524
Filed: 1989-02-08
Abstract: An interface circuit for use in connecting a high 
frequency piezoelectric transducer to an input stage of an 
echo ranging system is described. The circuit includes first (Q1), 
second (Q2) and third control transistors (Q3) which are selectively 
switched by a state controller (18) to control the operation of the 
circuit. The first transistor (Q1) is controlled to generate a 
coherent acoustical pulse at a first predetermined time. The 
second transistor (Q2) is controlled to damp the transducer output 
at a second predetermined time following the first 
predetermined time. The third transistor (Q3) serves to clamp the 
input stage of the echo ranging system to ground until the 
pulse signal has been effectively transmitted. This operation 
insures the transducer is in a condition to immediately 
receive an echo pulse despite the proximity of the transducer 
to the target whose range is being measured.

Title: Conductive ceramics, conductors thereof and methods
IPC: C04B35/45
Filed: 1989-03-30
Abstract: A ceramic of known composition exhibiting superconductivity below 
a critical temperature is caused to exhibit superconductivity or 
superconductor-like behaviour at room temperature by the application 
of an electrochemical potential. The effect is believed to arise from 
an increased population of the monovalent state of copper and other 
methods are proposed for creating such a population without cooling.

Filed: 1990-06-21
Abstract: A diaphragm controlled differential pressure control valve, in particular for hot water heating systems, having a controller housing (1) in which a valve plate (3) which interacts with a valve seat (2) is connected via a piston rod (4), which is guided in a sealed manner on the controller housing (1), to a diaphragm (20), which is clamped between diaphragm plates (19, 21), which divides a housing chamber into a negative-pressure chamber on the valve-seat side and a positive-pressure chamber, and which is stressed by an adjustable spring arrangement (11) in the direction away from the valve seat (2). In order to construct the spring arrangement (11) in the interior of the controller housing (1), a hollow hub (25, 26) is formed from the diaphragm plate (21) on the valve-seat side, or by the two diaphragm plates (19, 21), in which hollow hub (25, 26) the spring arrangement (11) is supported on the diaphragm plate (19) averted from the valve seat (2) and on a spring plate (10) which is screwed onto the threaded part (121) of an adjusting screw spindle (12) which is guided out from the controller housing in a sealed manner through the base wall (18) of the controller housing (1) averted from the valve seat (2) and which spring plate (10) is held in a rotationally fixed manner on a fork (13) which runs through the spring arrangement (11), passes in a displaceable manner through the spring plate (10) and is fixed to the housing. <IMAGE>

Title: Boat with a bow door
IPC: B63B27/14
Filed: 1990-12-21
Abstract: The boat has a flap (1) forming a part of its V- or spoon-shaped bow and being unfoldable therefrom. This flap is supported by means of projections (9a,9b) arranged on both of its sides on swivel joints (13a,13b) set back into the inside of the boat with respect to the inner wall of the bow. Upon pivoting the flap (1) out of the bow opening (15), the flap is swung away from the bow wall portion with the uncovering of an interspace (2) between the flap and the bow wall portion which latter lies underneath the bow opening (15). The flap outside wall can be urged underneath the surface of the water and can be fixed in its position. The flap (1) is designed as a buoyant member, and when serving as a working or recreational platform, etc., can be folded back into the bow of the boat in such a way that the hydro- and aerodynamic properties as well as the esthetic appearance of the bow are not impaired. The boat according to this invention can thus be utilized, without restriction of its full functional ability, as a rescue boat, salvage boat, pleasure boat, and speedboat. The configuration of the flap (1) acting as a buoyant member makes its use possible without impairing the stability of the boat; in the unfolded condition, this configuration even enhances the capsizing stability of the boat. Furthermore, the design of the boat hull is such that the stern engines, when a curve is traversed, do not leave the water (4), and the boat exhibits a very high capsizing stability.

Title: Light emitting diode scanner
IPC: G06K7/10
Filed: 1991-06-28
Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.
