Inventor: LACKNER JOHN R
IPC: A47L9/14
Filed: 1990-05-11
Abstract: A convertible vacuum cleaner providing a detach-able upright handle permits the vacuum cleaner to be used as an upright cleaner for cleaning rugs, carpets, and the like.   A detachable portable hand cleaner handle is also provided which is mounted when the cleaner is to be used as a portable hand cleaner.  A resiliently biased, releasable connector is mounted on the filter bag to detachably con-nect the filter bag to either of the handles.  The connec-tor is connected to the upright handle.  The connector is resiliently connected to the bag so that the bag remains in proper extended position in all operating positions of the upright handle.   A receiver having a socket and a mating blade on the handles permits the two handles to be selec-tively mounted on the power unit of the cleaner.   The portable handle provides a shoulder strap which is re-tracted into the handle by a reel when not in use and is locked at any selected extended position when the shoulder strap is in use.

Title: Electromechanical programmer assembly
IPC: H01H43/10
Filed: 1990-07-17
Abstract: ABSTRACT   An electromechanical programmer assembly for controlling electrically operated appliances having a rotatable cam drum operable upon motorized advancement to actuate and deactuate plural program switches for controlling appliance functions.  A user actuated shaft is rotated to select the desired cam drum position for program selection.  Axial movement of the sheet causes a cam thereon to lift a slider for opening a line power switch for controlling the motorized cam drive and engaging a friction detent on the cam drum for resisting rotation of the drum and to provide a tactilely sensed position indication to the user.  Axial movement of the shaft to effect dropping of the slider closes the line power switch and disengages the detent.

Title: Method and apparatus for doppler velocity de-aliasing
Inventor: WIELER JAMES G
IPC: G01S13/532
Filed: 1991-02-21
Abstract: Abstract of the Disclosure A method and apparatus for real time de-aliasing of the Doppler velocity data in a weather radar system by using a Process Radials routine which processes every valid range gate along a radar dwell by determining if each range gate is within the Nyquist velocity of either the average of four preceding range gates or data from a Windfield Model.  To further enhance the de-aliasing process a Process Dual Scans routine is used prior to the Process Radial routine to de-alias velocity data by comparing velocity data from two scans of different pulse repetition frequencies.  Subsequent to the Process Radials routine, a Minimize Azimuthal Shear routine checks velocity discontinuities from azimuth to azimuth.  The de-aliased data is transferred to an Update Windfield Model routine for quality checks of the de-aliased velocity data and updating of the Windfield Model.  This complete method of de-aliasing the velocity data is performed during the real time operation of the radar system.

Title: Coaxial cable
Inventor: YUTORI TOSHIAKI
IPC: H01B11/18
Filed: 1991-06-21
Abstract: A coaxial cable comprises an inner conductor consisting of a very fine metal wire having a diameter of 120 µm or below and a tensile strength of 100 kg/mm or above, and a plated noble metal layer coating the very fine metal wire, an insulating layer of an insulating material coating the inner conductor, an outer conductor coating the insulating layer, and a jacket coating the outer conductor.  In forming the inner conductor, a metal wire is coated with a noble metal layer by plating, and then the metal Wire coated with the noble metal layer is subjected to plastic working to reduce the diameter and to improve the structure of the noble metal layer.  A high-frequency signal applied to the coaxial cable is transmitted through the noble metal layer of a satis-factory structure by skin effect without being disturbed.  The very small diameter and very high tensile strength of the very fine metal wire of the inner conductor enables the coaxial cable to be formed in a very small diameter.   Such performance and structure of the coaxial cable is advantageous in its application to electronic equipment in-cluding IC chip testers and high-speed electronic computer systems.

A quantity of white lime equal to approximately 4% of the weight of the clarified sludge, depending on the acid content of the mixed refuse, is added. Stirring is continued for a further residence time of 69 to 70 hours. An installation for carrying out the process, with a container for the refuse to bedecomposed, including feed and discharge devices and screw conveyors for stirring the mixed refuse, comprises a parallelepipedal container (1) with a heptagonal profile in the shape of an inverted house roof with its ridge pole sunk in the ground and whose width (b) is greater than its length (I).

Title: Optical frequency deviation measure and control device for laser light
Inventor: MIYATA HIDEYUKI
IPC: H01S3/13
Filed: 1992-03-13
Abstract: Abstract of the Disclosure The operating point is stabilized at the MAX or the MIN of its optical frequency discriminating characteristic. Under the stabilized operating point, the detected difference between the average of the light intensity and a set value is fed back to a data modulator so that the average value converges on a set value when a predetermined optical frequency deviation is produced. The operating point is also stabilized at the MED of said characteristic. Under the stabilized operating point, a low-frequency signal component is extracted from an electric signal output by means of synchronous detection. The operating point is stabilized at the MAX or the MIN of said characteristic. Under the stabilized operating point, a low-frequency signal component is twice in frequency by means of synchronous detection. In the fourth and fifth aspects, means such as synchronous detection is not required for the stabilization control of an operating point.
