Abstract: TITLE:  AN  ANGLE  COUPLING  STRUCTURE  FOR  KNOCKDOWWN  CABINETS            ABSTRACT OF THE DISCLOSURE    An angle coupling structure for knockdown cabinets includes an angle coupling,  a plurality of connectible sections, and a plurality of securing aid.  Within each of  the  connectible section,  an elongate  chamber  is formed to receive a connecting rod projecting from  the angle   coupling  and  an  elongate  recess  is  formed generally below the elongate chamber to receive one  of the  securing aids and permitting the same to  slidably move  therein.   An elongate slot is formed on the wall between the chamber and the recess.   While a screw  is put through the hole preformed on the securing aid,  it may  pass  the  elongate slot to screw  into  the  hole formed  on  the  connecting rod precisely  due  to  the adjustable   position   of  the  securing   aid.    The connectible sections,  angle coupling, and the securing aids are thus joined together tightly.

Title: Modular resonant cavity, modular dielectric notch resonator and modular dielectric notch filter
Inventor: BENTIVENGA SALVATORE
IPC: H01P7/10
Filed: 1991-03-04
Granted: 1995-01-10
Abstract: ABSTRACT OF THE DISCLOSURE    Modular resonant cavities particularly for use in applications associated with high frequency electromagnetic energy each comprise a shell defining an aperture formed therethrough, and either end plates and/or divider closure plates, each having stepped-down regions for interfitting at perimeter ends of adjacent shells so as to form a resonant cavity.  The modular resonant cavities include support rods passing through the corner regions of each closure plate.  Fastening means at each end of the rods mechanically secure the modular resonant cavities together.  The modular resonant cavities are particularly suited for forming dielectric notch resonators and in particular, such dielectric notch resonators having a centrally positioned resonators within the aperture defined by each shell and a coupling reactance mechanism formed by an inductive coupling wire and a capacitive element connected in series thereto so as to form a dielectric notch resonator with a relatively narrow bandwidth and with a small imaginary component about its operating center frequency.  Dielectric notch filters using a plurality of such dielectric notch resonators further comprise a coupling transmission line which connects to each dielectric notch resonator resulting in an overall filter having a shorter overall length than comparable filters formed by prior art dielectric notch resonators.  The resulting dielectric notch filter has a lower electrical loss than previous dielectric notch filters using longer coupling transmission lines.

Abstract: In a photographic copy process the copy master is scanned in intervals, by a source of measuring light. The measuring light is spectrally split, detected and converted into electrical measuring signals. The n spectral measuring signals are converted into n spectral density values, compared with neutral densities and n spectral density differences formed.      In a data compression the n spectral density differences are converted by an orthogonal transformation to m < n transformation coefficients. The transformation coefficients are analyzed in a color and density correction routine and deviations computed. From the deviations the copy light quantities and exposure corrections adjusted to the copy material are determined. The photographic copies are produced by the exposure values determined.

Title: Method of creating an index grating in an optical fiber and a mode converter using the index grating
Inventor: HILL KENNETH O
IPC: G02B5/28
Filed: 1992-06-30
Granted: 1999-08-17
Abstract: Efficient, narrow-band rocking filters have been made in polarization-maintaining monomode optical fiber by photoinducing periodic birefringent gratings along the length of the fiber. These gratings, fabricated with a period chosen to provide synchronous coupling between the two principal states of polarization of the LP01 mode at a preselected wavelength, gently rock to and fro the principal polarization axes of the fiber. To photoinduce the grating, the fiber is exposed periodically along its length to a U.V. light beam which is incident at right angles to the geometrical axis of the fiber and is directed .pi./4 radians with respect to the principal axes. Efficient polarization mode conversion at 1.3 µm with the fiber gratings are obtained.

Abstract: A fluid mixing accessory comprising a mixing receptacle integrally formed with a funnel. The accessory is formed of a flexible material which is light-weight and disposable.      The measuring receptacle is a graduated cone for measuring the components of a mixture, such as the color, the hardener and the reducer of a paint composition. The funnel has an opening, which, depending on the nature of the fluid being mixed, may include a gauze or mesh to act as a strainer. The funnel and the measuring receptacle are joined by a connecting portion. Thus, once the fluid has been mixed in the mixing receptacle, the accessory is inverted so that the mixture runs from the receptacle, across the connecting portion and into the funnel which is positioned over a container. After the funnel has emptied, the entire device then can be collapsed and discarded. The funnel is collapsible for convenient shipping and storage.

Abstract: An in-line skate is shown, including a rigid plastic chassis  having  a  main  portion  and  integral  wing  portions extending upwardly therefrom on either side adjacent the heel end of the chassis, with an integral heel portion between the wing portions.   The main portion, heel portion and wing portions together define a heel box area.  A plastic boot is secured to the chassis  inside the wing portions and against the heel portion, and extends forwardly along the chassis.  A plastic cuff wraps around either side and the rear above the boot, and is pivotally connected to each wing portion.  A soft flexible padded sock-like liner is positionable inside the boot and the cuff. Straps are provided to secure the cuff, boot and chassis around the liner to firmly secure the user's foot, the straps preferably including at least one strap passable across the front of a user's ankle, the opposite ends of the strap being directed generally towards the heel box area, such that tightening of the strap pulls a user's heel directly into the heel box area. Preferably, the boot is adjustable to toe in or out relative to the chassis, and the pivotal connection between the cuff and the wing portions includes adjustment means on at least one side, whereby the height of the cuff relative to the wing portion on that side may be adjusted. The cuff is positioned inside the wing  portions,  and  the  boot  and  the  cuff  are  generally complementary  in  shape  and  thickness,  thereby  presenting generally flush interior surfaces to the liner.

Abstract: A radiotelephone system reduces noise interference during handoff by muting the audio path of a receiver employed in a target base-station (135). After receiving a handoff request message, a target base-station (135) mutes the target audio path and determines if the target audio path had been enabled by an undesired interfering signal having a common SAT. If the target audio path had been enabled by an interfering signal having a common SAT, the target base-station (135) will use the SAT and the received signal strength indication (RSSI) of the desired transmission of the subscriber (125) to enable the target audio path. Once the SAT and RSSI are present and adequate the target audio path is enabled, the source audio path is coupled to the target audio path, and the subscriber (125) is handed off from the source base-station (130) to the target base-station (135) without a third party experiencing an objectionable noise blast.
