Abstract: AIRCRAFT GROUND PROXIMITY WARNING INSTRUMENT        ABSTRACT OF THE DISCLOSURE An aircraft instrument for warning the pilot that the aircraft is in an unsafe condition in proximity to the ground.  The instrument has inputs representing aircraft configuration, flight condition with respect to the ground, and glide slope.  Detector circuits process the inputs and give a warning of unsafe proximity to the ground.  The boundary conditions for the warning are selected to avoid false warnings.  A glide slope detector dis-tinguishes between a valid glide slope signal and spurious signals, without need for pilot input.

Title: Low profile-low bounce electrical switch apparatus
Inventor: KEMPF DEAN R
IPC: H01H13/52
Filed: 1975-06-30
Granted: 1979-02-20
Abstract: ABSTRACT OF THE DISCLOSURE         Extremely low bounce switching characteristics are achieved by biasing electrical switch conductors with a torsion beam member.  The torsion beam member includes a torsion beam portion having an axis which is restrained from rotation thereabout at a first point and an operating beam portion connected to the torsion beam portion at a second point spaced from the first point.  The axis of the operating beam is oriented at an angle with respect to the axis of the torsion beam such that displacement of the op-erating beam causes rotation of the torsion beam from a quiescent rotational state thus producing a torsional bias force against such displacement. At least one of the switch's electrical make/break conductors is operatively associated with the operating beam for displacement there-with while the remaining electrical conductor is disposed for making or breaking the electrical contact upon displace-ment of the operating beam.  A special preferred embodiment includes complementary shaped mating unitary electrical conductors which are shaped so as to constitute both the torsion beam member and the electrical contact member of the switch.  This preferred embodiment results in a very low physical profile and low bounce switch which has dual self-wiping electrical contacts and which is simply formed from only two unitary electrical conductors and two molded plastic members.

Abstract: Abstract of the Disclosure A dielectric processing chamber unit for use in electroprocessing large surface areas including electro-polishing and electroplating.  The processing chamber unit has an open face, an open top, a sealing strip, an electro-lyte inlet and an electrode.  The processing chamber unit is placed with its open face against a surface to be electro-processed and an electrolyte is introduced into the chamber through the inlet.  The inlet is located so that the enter-ing electrolyte dislodges gas bubbles formed during electro-processing and then both the electrolyte and gas leave the chamber through its open top.         A method of electroprocessing a surface using such a processing chamber unit whereby a relatively small amount of electrolyte is used and recirculated during processing. In this method, the chamber unit is used to electroprocess the inner surface of a vessel concentric about its longi-tudinal axis whereby the processing chamber unit is temp-rarily mounted from a shaft maintained on this axis and the chamber unit is rotated around the interior of the vessel during the electroprocessing procedure.

Abstract: ANTI-LOCK BRAKE CONTROL CIRCUIT          Abstract of the Disclosure:         An anti-lock brake control circuit compares the deceleration of a braked wheel with a deceleration reference and integrates the difference when wheel deceleration exceeds the reference deceleration.  A resulting velocity error sig-nal is compared with a velocity error reference and a release signal is generated while the velocity error signal exceeds the velocity error reference.  Adaptive control is provided by a first order lag circuit having wheel velocity as its input and which supplies a variable portion of the decelera-tion reference having a slope approximately equal to the slope of the vehicle velocity profile during braking on low coeffi-cient surfaces and having a slope less than the slope of the vehicle velocity profile during braking on high coefficient surfaces.  An initial cycle and pulse circuit sets the velocity error reference to a high level for both the first cycle of anti-lock brake operation and for a time period after each brake application during anti-lock brake operation.

Abstract: ROTARY KILN PLANT ABSTRACT OF THE DISCLOSURE A plant is disclosed for heat treating pulverous raw material such as cement raw meal prior to a final sintering pro-cess in a rotary kiln. The plant includes a rotary kiln having an upper material inlet end portion for the reception of preheated cement material and a lower material outlet end portion for exit-ing the final sintered kiln product. A multi-stage cyclone string preheater having at least a first stage for receiving the cement raw meal has a last stage communicating with the upper material inlet end portion of the kiln. A smoke chamber connects the upper material inlet portion of the kiln with the preheater, and a scoop chamber connects the kiln with the smoke chamber. The scoop chamber is adapted to receive preheated, at least partially calcined raw material from at least one preheater stage other than the last stage. The cement material received in the scoop chamber is dispersed so as to be suspended in the gases exiting the kiln and directed through the smoke chamber to the last stage of the associated preheater string. The preheated, at least partially calcined cement material is then directed from the last stage of the preheater string to the upper material inlet end portion of the kiln at a location upstream with respect to the kiln exiting gases, of the location of the dispersing means, so as to pass down through the kiln for further heat treatment. -1-
