Patent CA-2006556-A1 (CA)
Inventor: WEYRAUCH ADOLF
IPC: G02B23/00
Filed: 1989-12-22
Abstract: The invention relates to a binocular telescope having cardanically journalled inverting systems mounted on a symmetrical double holder. This double holder is connected via a spring joint to a stationary non-movable base frame which is mounted at the pivot point of both inverting systems. A passive movement damping device provides for a field image stabilization in the telescope. The monolithic spring joint has a spring arrangement perpendicular to the optical axis with the springs being thickened in the axial direction toward the edge to improve supporting capability. Shock protection is provided in the region of the support pivot point and contains an unlatchable device. The passive damping device is configured as an eddy current device and includes a magnetic system about a stationary eddy current coil which has a nonlinear effect for the purpose of adjusting axially the damping constants. Isolated coils are disposed on the eddy current plate and can be short-circuited by means of a switch so that a specific, time-limited change of the damping constant is possible.

Title: Water heater package construction and method
Inventor: MATTINGLY BRUCE W
IPC: B65D85/68
Filed: 1990-01-04
Abstract: Abstract of the Disclosure A composite package for a water heater includes a two-part folded cardboard assembly as a top support panel and a two-part folded cardboard assembly as a bottom support panel.  The two members that comprise the top support panel each begin as a generally rectangular cardboard member which is folded so as to result in a double-thickness center area and oppositely disposed downwardly depending side walls. These two members are then turned 90 degrees to each other so as to create an open, box-like structure.  Virtually the same procedure is followed for the fabrication of the bottom support panel.  Each of the four folded cardboard members include a centrally disposed and generally rectangular reinforcement which may either be plastic, metal or a similar relatively rigid material and this reinforcement is secured to the folded cardboard.  After the water heater is placed within the bottom support panel and the top support panel is attached to the top of the water heater, bands are arranged around the entirety of the assembly and tightened so as to draw the top and bottom support panels toward one another and against the opposite ends of the water heater. For added bracing and support, corner braces are installed in the corners of the bottom support panel so as to be contiguous with the outer surface of the water heater.

IPC: H04N7/30
Filed: 1990-02-12
Abstract: A method of writing and reading coded data writes and reads the coded data which are coded by an orthogonal transform coding so that an original image can be restored progressively or sequentially, where the original image is divided into blocks of an arbitrary number of pixels and the coded data are obtained by coding quantization coefficients which are obtained when gradation levels of the pixels within each block are subjected to a two-dimensional discrete cosine transform.  The method comprises the steps of extracting the quantization coefficients for each restoration stage, subjecting the extracted quantization coefficients to a variable length coding, writing the variable length coded quantization coefficients into storage means as the coded data, reading the coded data from the storage means, restoring a code length of the coded data based on the read coded data, extracting coded data corresponding to the restored code length from the read coded data, and outputting the extracted coded data as coded data required in each restoration stage.

Title: Planar slotted antenna with radial line
IPC: H01Q21/00
Filed: 1990-08-17
Abstract: The invention provides an inner-feed-type planar antenna of single-layered structure excited by an axially symmetric mode for propagating radio waves from the center toward the outer periphery within a propagation layer having an antenna surface.  If the planar antenna is used for transmission, the antenna is provided with a plurality of coupling slots formed and arrayed in one surface of an axially symmetric mode waveguide member in such a manner that the coupling factor of the external radiation is high at the outer periphery and becomes successively lower as the center is approached.  A spiral- or ring-shaped terminating slot is provided in the antenna surface at the outer portion of the axially symmetric mode waveguide member.  A region not coupled with the outer portion is provided at the center of the antenna surface.          Furthermore, the planar antenna is provided with a reflector member arranged along the terminating slot for reflecting a propagating radio wave between the inner and outer portions of the axially symmetric mode waveguide member.  Accordingly, a comparatively flat aperture distribution in which the electromagnetic field is uniform can be obtained.  In addition, by providing the central portion with a non-radiating region, long-line effect is suppressed and bandwidth enlarged.
