Abstract: STOICHIOMETRIC AIR/FUEL RATIO EXHAUST GAS SENSOR                     ABSTRACT OF THE DISCLOSURE          A stoichiometric air/fuel ratio exhaust gas sensor construction particularly useful with variable resistance partial pressure of oxygen responsive sensor material is disclosed.  A generally cylindrical mounting body, formed of corrosion resistant material, is arranged for receipt within the exhaust system of an internal combustion engine and is provided with a ceramic insert member for support of a wafer of variable resistance sensor material.  The ceramic insert member is comprised of an extending first portion having a hollow slotted tip for receipt and support of the wafer of partial pressure of oxygen responsive ceramic sensor material. The extending first portion of the ceramic insert member is arranged to position the wafer within, and extending from, a remote free end of the cylindrical housing body.  The wafer includes a pair of extending high temperature resistant electrical conductors which are received within bores provided therefor in the extending first portion of the ceramic insert member.  The wafer leads are electrically connected by a glass seal material to a pair of electrically low resistance, high temperature resistant relatively rigid connector pins which are received within a pair of passages extending from the rear face of the ceramic insert member and intersecting the wafer conductor passages.

Abstract: ABSTRACT OF THE DISCLOSURE    A resistive fluid detecting means utilizes a probe means having three electrically conductive areas that are interconnected between a power source and an amplifier. The detecting means is particularly useful in detecting the presence or absence of water in a boiler used in a heating plant. The presence of water between two of the electrically conductive areas reduces the resistance of that path so that the amplifier responds and operates an output switch, which in turn can be used to energize a fuel burner for the boiler. If boiler scale builds up on the probe means or if the water or fluid rises too high, the electrically conductive areas shunt current away from the amplifier and allow the output switch to open.

Abstract: Abstract of the Disclosure A window mounted antenna for use with, for example, a car radio, is disclosed.  The antenna has a central fishpole-type portion which contri-butes predominantely to the metric wave band and a frame portion running beside the edge of the window and which contributes predominantly  to the medium wave band.  Each portion, however, contributes in the range of 10-20% to the reception of signals having a frequency predominantly received by the other portion.  This is achieved by modifying the impedance of the central portion by forming the frame portion as a flat spiral at the location where the frame and central portions join, thus providing proper matching between the antenna of the receiver feeder for both the metric band the and medium band.

Abstract: ABSTRACT OF THE DISCLOSURE         An actuator comprises a piston and cylinder in which the piston is biased axially inwardly of the end of the cylinder to an intermediate position by two bias mem-bers respectively on axially opposite sides of the piston.          Limit means associated with each respective bias member serve to coact between the respective bias member and the cylinder to limit the inward travel of the respective bias member in the cylinder to establish a constant position at which the piston receives no net biasing force from the two bias members.  Each limit means may comprise a flanged cup which moves with the inner end of the bias member and a stop surface in the cylinder for engaging the cup flange to limit its inward movement, and thus the inward movement of the bias member.         In one application the actuator forms part of a surface traversing apparatus, with the cylinder being fixed to a base portion of the apparatus and the piston serving to selectively position anchor fingers connected thereto to each of three precise positions relative to the cylinder in response to fluid pressure on the piston.

Abstract: HYDRAULIC DEVICE            Abstract of the Disclosure:   An improved hydraulic device in-cludes a rotor which is circumscribed by a cam surface.  A series of peripheral slots are formed in the rotor.  Each of the slots receives a pumping element which is spring urged toward engagement with the cam surface as the rotor is rotated relative to the cam surface.  Each rotor slot defines a spring receiving recess extending from one major side surface of the rotor to a location between the major side surfaces of the rotor.      The recess allows axial movement of a portion of the spring in one axial direction and blocks axial movement of that portion of the spring in the other axial direction.  Each pumping element preferably defines a spring receiving recess which allows axial movement of another portion of the spring in the opposite axial direction and blocks movement of the spring in the one axial direction.  The spring recesses facilitate assembly of the hydraulic device and resist undesirable spring movements during operation of the device.

Abstract: RASTER DISPLAY POSITION DETECTION           Abstract of the Disclosure In order to accurately detect and communicate the position of a data location in a raster type luminescent display utilizing light-sensitive detection means, the permitted response time for the light detection means is extended by allowing detection of only a portion of the data locations during each scan of the raster display means.  Maintenance of a predetermined rela-tionship between the number of raster scans in a detection cycle and the par-ticular data locations for which detection is possible on each scan permits exact definition of a tarot data location.  Detection is aided by the super-imposition of a luminescent cursor associated with each data location for which detection is permitted as the raster display is scanned.

Abstract: SECTORED ANTENNA RECEIVING SYSTEM              ABSTRACT OF THE DISCLOSURE    A plurality of horizontally directive antenna sectors are arranged in configuration to receive signals from remote transmitters over a given angle in the horizontal plane.  A scanning system is operative in one of several modes to sequentially couple each sector to a receiver.  In its first mode, each sector is sequentially scanned with the peak signal level therefrom being compared to a reference level.          If the signal level on any sector exceeds its reference level the scanner activates to its second mode wherein scanning of all sectors continues for a predetermined interval after which the system advances to a selective scanning mode wherein scan is limited to that sector with the largest stored signal level relative to its reference level, and to those sectors adjacent said sector.  At the end of this interval, scanning is inhibited and the receiver is coupled to that sector which exhibited the strongest relative signal level during the scanning sequences.  In this inhibit scan mode, if the signal level from the sector falls to a minimum level for a given time period the system reverts to the first scanning mode.    The system periodically updates the reference levels to account for changes in background noise or the presence of an interfering signal.
