Abstract: PATENT SPECIFICATION     ANTI-COLLISION VEHICLE RADAR SYSTEM  .            ABSTRACT:     The anti-collision vehicle radar system overcomes inter-ference problems due to radar beams from similar radar systems on other vehicles by providing a radar transmitter having a trans-mitting antenna which transmits a radar beam having circular polarization with a particular direction of rotation of the polarization, a radar receiver for receiving the radar beam after reflection thereof and including a receiving antenna having means for discriminating in favor of received signals having circular polarization with said particular direction of rotation while discriminating against received signals having circular polarization with the opposite direction of rotation of the polarization, the receiving antenna thereby being effective to discriminate in favor of a reflected radar beam from the associated transmitting antenna while discriminating against any interfering radar beam from another vehicle radar system, and utilization means connected to the receiver for utilizing received radar signals to control the operation of the vehicle.  For example, the brakes of the vehicle may be applied if the received radar signals indi-cate that the vehicle must be stopped to avoid a collision.  The transmitting and receiving antennas may include helical antenna elements which are coiled in opposite directions to achieve such discrimination.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is a fire-tested butterfly valve having an annular resilient seat member an and annular flexible metal seat member, both held in place in a valve housing by being clamped between cooperating surfaces of the valve housing and a valve seat retaining ring insert. In a first embodiment, a fusible washer with a lower destruction temperature than that of the annular resilient seat is positioned between the resilient seat and the metal seat.  In a second embodiment, an in-tegrally formed protrusion on the annular resilient seat contacts the metal seat.  In both embodiments, the metal seat is held out of contact with the butterfly disc until exposure to a fire melts the fusible washer or the seat protrusion, at which time the metal seat comes into contact with the disc to establish a secondary metal-to-metal fire resistant seal.

Abstract: INTERVERTEBRAL DISC PROSTHESIS Abstract of the Disclosure The invention concerns an intervertebral disc prosthesis intended to replace a natural intervertebral disc and to restore the normal intervertebral spacing without complete loss of flexibility of the spinal joint.          The prosthesis comprises a body of biologically-acceptable material suitably dimensioned and shaped to replace a natural disc.  One of the longitudinal ends of the pros-thesis has suitable means, e.g. a raised flange, to facilitate handling of the prosthesis and to prevent penetration to an excessive depth into the spinal joint.       The other longitudinal end is preferably wedge-shaped to facilitate insertion into the intervertebral space.  The superior and inferior surfaces are preferably provided with surface characteristics to produce a "friction-fit" and are convex to correspond to the adjacent vertebral surface.  The prosthesis is inexpensive to manufacture and can be implanted quite easily with little danger to the patient.  Moreover, the prosthesis maintains at least some of the flexibility of the joint while remaining firmly anchored in place.

Abstract: OPTIMIZATION OF ERROR DETECTION AND CORRECTION CIRCUIT               By Brewster J. Porcella ABSTRACT OF THE DISCLOSURE           There is provided an error detection and correction circuit which is optimized in terms of the operation, part count and the like.  This invention includes parity generator circuitry to generate parity signals in accordance with a variation of the Hamming Code in response to the application of a plurality of input data bits.  The parity signals are applied to a memory bus during a write cycle.  During a read cycle, the parity generators produce a parity error signal, if appropriate, to indicate an error in parity.  The error correction circuit receives the data bits from the memory or memory bus along with the parity error signals generated by the parity generator circuit portion.  The data signals and parity error signals are gated together and supplied to Exclusive-OR gates. If an error is indicated by the level of the input signal, the Exclusive-OR gate converts the signal thereby correcting the er-roneous data bit.  The circuit further provides means for checking the parity of the parity bits, per se, thereby to provide a double bit error check.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to electric heater units for "smooth top" cookers which employ two or more heater elements in the same unit.  It is directed particularly at the prob-lem of monitoring the temperature of the unit and/or the "smooth top" thereover to protect against overheating.  It is known to use a thermal cut-out device extending over the heater unit where a single element is used, but design prob-lems develop when two or more elements are employed in the same unit, of which at least one is independently energisable.          According to the invention an elongate thermal cut-out device (16) extends across said one element (10) but is thermally isolated from the other element or elements (12).          Thus, the device (16) operates only in response to the one element (10).  Such thermal isolation can be accomplished by enclosing a portion (30) of the device (16) which extends across the other element or elements in a block (26) of thermal insulation material, or in a sheath (32) of thermally conductive material which carries any heat from the other element or elements to a heat sink (2).  In a third alterna-tive, the effective length of the device terminates at the boundary (14) of the one element.
