Abstract: APPARATUS WITH HEAT EXCHANGE MEANS FOR TREATING     SOLID, GRANULAR AND AGGREGATE MATERIALS            ABSTRACT OF THE DISCLOSURE        An apparatus (14) embodying heat exchange means for treating solid, granular and aggregate materials, and in particular for treating spent, i.e., used, chemically bonded foundry sand.  The subject apparatus (14) includes a rotatable first chamber means (16) in which the used foundry sand is preheated while traveling in a first direction there through from one end thereof to the other end thereof.  From the first chamber means (16) the preheated used foundry sand is suitably conveyed to a thermal reclaimer means (12) for purposes of thermally removing organic matter therefrom.  Thereafter, the used foundry sand is conveyed to a second chamber means (44) wherein the used foundry sand undergoes post reclamation whereby any organic matter that may yet remain in the foundry sand is thermally removed therefrom.  From the second chamber means (44) the used foundry is made to pass into a third chamber means (52) which is located in surrounding heat exchange relation to the first chamber means (16).  As the used foundry sand flows through the third chamber means (52) in a second direction heat is exchanged between the foundry sand traveling through the third chamber means (52) and the foundry sand traveling through the first chamber means (16) such that the former loses heat, i.e., is being cooled and the latter absorbs heat, i.e., is being preheated.

Abstract: Abstract of the Disclosure Belt Tensioning Mechanism A belt tensioning mechanism is provided for use with a vehicle having an axle pivotably connected to a frame of the vehicle with inextensible belts entrained about wheel assemblies mounted on either side of the vehicle for transmitting tractive effort to the earth.  Some systems provide tensioning of belts by producing a separating force between only the wheel assemblies on one side of the vehicle independent from the tensioning of the other side while others provide tensioning of track having sprocket driving-members by using bulky complicated mechanisms for providing the tensioning of the track and to provide relative motion of the front axle from one side to the other.  In the subject arrangement, an axle is connected to a frame by a swivel bearing being slidably disposed on a pin, such that, the axle moves longitudinally relative to the frame while still being able to swivel about the pin.          Furthermore, an adjusting mechanism is provided to produce the force necessary to sufficiently tension the belts to provide frictional drive between the belts and the drive wheel assemblies.  In one of the embodiments, the adjusting mechanism includes a force generating mechanism responsive to fluid pressure transmitted thereto from a pump. This arrangement allows the axle to move relative to the frame in the longitudinal direction in the event that a foreign object passes between one of the belts and its respective wheel assembly without requiring a large bulky mechanism that would be impractical for use on large industrial vehicles.

Abstract: DIGITAL ACCELEROMETER                       Abstract A digital accelerometer comprising a linear analog accelerometer and a digitizer. The analog accelerometer includes a housing and conductor means extending outside the housing, and is adapted to produce on the conductor means an analog signal representing linear acceleration along one axis. A casing is positioned against the housing so as to form a substantially enclosed space between the housing and the casing. The digitizer is located within such enclosed space and receives the analog signal and produces a corresponding digital signal. Interface means may also be positioned within the enclosed space for receiving the analog signal and producing a second analog signal that is input to the digitizer. The digital signal produced by the digitizer may be conveyed to a location outside the enclosed space and housing by a flexible strip of insulating material having a plurality of conductive strips embedded therein. In a preferred embodiment the interface means includes an interface circuit operative to determine the magnitude of the second analog signal resulting from a particular first analog signal, whereby the dynamic range of the digital accelerometer can be modified by modifying only the interface circuit.

Abstract: ABSTRACT           A television broadcast transmitter includes two power amplifiers or transmitters, a dummy load and an antenna. A noncontacting switching arrangement includes 3dB directional couplers or hybrids operated as controllable phase-shifters under the control of pairs of variable reactive terminations.  The signals arriving at the antenna or load port by two paths are combined in-phase to couple signal to that port, or combined out-of-phase to cancel signal at that port.  If the out-of-phase condition is not accurate, the cancellation may be incomplete, resulting in crosstalk.  In order to avoid the need for highly accurate positioners to position the variable reactive termination at the particular position providing the desired phase-shift, a particular structure of the reactive termination is used.  The reactive termination is a short-circuited coaxial line with an axial gap in the center conductor at a position less than one quarter wavelength from the short circuit. The center conductor is hollow in the region of the gap and lined with insulating material, and an elongated conductive slug is actuated to selectively occupy one of two positions within the hollow center conductor, one position remote from the gap whereby a minimum series capacitance results, and the second position straddling the gap, whereby the series capacitance increases.  The slug is actuated by a dielectric rod passing through the short circuit.  The rate of change of phase-shift as a function of actuator positions is very small near the extremes of actuation position, whereby small errors in actuator position do not materially affect the phase-shift.

A measuring cell is inserted into the measuring tube wall in each of these areas or regions and includes a mobile pressure sensing element against which acts the pressure of the medium surrounding the measuring tube.          An end of the pressure sensing element projects into the inner space of the measuring tube and, for measurement, a measuring wheel of a measuring probe is brought into position underneath the end of the pressure sensing element such that the latter is moved radially outwards against the pressure exerted on it.          The force which thus acts on the measuring wheel is determined by a measuring device for measuring the pressure.  The medium to be measured does not enter or leak into the measuring tube since the measuring cell is sealingly inserted into the measuring tube.  The measuring wheel is brought very accurately into the measuring position by the rotation of a central portion of the measuring probe relative to the end portions, which are guided on wheels, and the movement of the probe until it makes contact with stops. This is a pre-condition for high precision pressure measurement.
