The impedance matching means displaying an impedance which varies between a first impedance at the connection to the second electrically conductive coupling member which is substantially equal to the impedance at the base end of the primary radiating element and a second impedance at least several orders of magnitude less than the first impedance.  Means for connecting transmission line means to the impedance matching means at a point where the impedance of the impedance matching means is substantially equal to the impedance of the transmission line.         In a first embodiment the primary and secondary radia-ting elements are mounted on opposite sides of a dielectric panel such as a window which capacitively couples the primary radiating element to the transmitter and/or receiver.  In an alternative embodiment, the primary and secondary radiating elements are commonly mounted to the interior surface of a dielectric panel.

Title: Stored-program controller with a conditional branch facility as for a video signal processor
Inventor: SPRAGUE DAVID L
IPC: G06F9/26
Filed: 1988-11-10
Granted: 1992-10-20
Abstract: RCA 84,950 Abstract A video signal processor includes a stored-program controller which concurrently reads two instruction values from a program memory during each instruction cycle.  The next instruction used by the video signal processor is selected from between these two values. If the current instruction indicates a conditional branch operation, the value of one of a plurality of conditions internal to the video signal processor determines which of these two instructions is selected.  Otherwise, a value provided by the current instruction itself determines which of the two instructions is selected.  This configuration of the stored program controller implements a conditional branch facility in which there is no delay in fetching an instruction for either value of the selected condition.

Abstract: ABSTRACT OF THE DISCLOSURE             A multi-roller conveyor includes a plurality of idler rollers journaled for rotation around individual, stationary shafts.  Each roller includes, at each of its ends, a metal end plate and an end bearing, received in the end plate, for rotatably supporting the roller relative to the shaft.  To protect against the entry of contaminants, an end seal assembly, including an inner seal member mounted to the roller, and an outer seal member, mounted to the stationary shaft, is provided at each end of the roller.  The inner and outer seal members are formed of molded plastic and co-operate with each other, and with the roller end plate, to form a labyrinth-like passageway leading from the end bearing to the exterior of the roller.  The outer seal further includes a metallic nut for facilitating mounting to the stationary shaft.  In addition, the dimensions of the roller end plate adjacent the outer seal member are carefully controlled to reduce the clearance between the outer seal member and the end plate and thereby further guard against the entry of contaminants.

Abstract: A liquid level gauging system and sensor device for installation in the aperture of a wall of a liquid-con-taining vessel, including a metal fitting having a through bore and a substantially cylindrical body por-tion with external threads by which it can be secured in the aperture in the vessel wall, a cup-like enclosure disposed in the bore, the enclosure having a bottom wall containing a prism disposed adjacent the inner end of the bore, and a light source and a light-responsive de-vice mounted in the enclosure. The prism has a substan-tially conical forward end portion for immersion in the liquid to be monitored. The conical forward end portion of the prism is characterized by an axis, and the prism has a light-admitting and light-transmitting conical recess coaxial with the conical end portion of the prism.          Light rays from the source that pass into the surface of the conical recess are bent, by refraction, toward the conical end portion. Reflected rays from the conical end portion passing outwardly through the surface of the conical recess are similarly bent, by refraction, toward the light-responsive means. The advantage of the present invention is that especially high resolution and accuracy are possible, while maintaining good reliability and repeatability.

Abstract: ABSTRACT    Apparatus   and   method   for   expediting  the translation of  a  virtual  address,  provided  by  a central  processing  unit,  to  a  real  address, for accessing a cache memory  unit,  is  described.   The technique  relies  on  the fact that a procedure will typically address locations in a  limited  number  of memory data pages during significant intervals of the procedure execution.  A small associative  memory  is provided  that, in response to at least a portion of the virtual page number,  rapidly  provides  a  trial portion  of  real  page number.  The trial portion of the  real  page  number  is  used,  along  with   the (unchanged)  word  portion  of the address, to access the cache  directory  unit  simultaneously  with  the complete  translation  of  the virtual page number to real page number.  The trial portion of the real page number is compared with the translated portion of the real page number.  When the comparison is false,  the location  address  is  used  to  access  the  cache directory unit and the cache memory unit operates  in typical  manner.   When  the  comparison is true, the correct  cache  directory unit  location  has   been accessed,  the comparison of the cache directory unit contents with the translated comparison  address  can be  performed  and  access of the cache storage unit, where appropriate, can proceed.
