Abstract: Abstract Of The Disclosure A feed horn for a reflector-type microwave antenna comprises a smooth-walled conical horn and a lining of absorber material on the inside wall of the horn for reducing the width of the RPE (radiation pattern envelope) in the E plane of the antenna.  The lining of absorber material extends from the wide end of the conical feed toward the narrow end thereof, terminating at a point where the horn diameter is about 7 times the longest wavelength of the microwave signals being transmitted.  The width of the RPE in the E-plane of the antenna can be reduced to be nearly equal to the width of the RPE of the H-plane of the antenna without significantly degrading this H-plane RPE from its shape without absorber and without significantly changing the gain of the antenna.

Title: Encoder for transmitted message activation code
Inventor: FENNELL ROBERT D
IPC: H04W88/18
Filed: 1982-10-07
Granted: 1984-12-18
Abstract: Abstract The encoder which preferably produces a transmitted digital word which serves as an activation code for a single receiver or a group of receivers.  The activation code effects only the receiver(s) that have previously detected their digital address and are therefore prepared to enter a message receive state.  The activation code transmitted by the encoder will cue the receiver(s) simultaneously thereby allowing the encoder to send a single message to a plurality of receivers.  The activation code also allows the encoder to interleave messages to receivers by utilizing the customary transmitter down time in a single message transmission. During this down time, the activation code allows the transmitter to begin transmission of a second message to a second receiver.  The use of the activation code to interleave messages is especially important in tone and voice transmissions since it significantly increases the efficiency of a heavily loaded system.

Abstract: WORN TOOL DETECTOR                        ABSTRACT         A worn tool detector system for analyzing input signals from a sensor were the signal is in the form of an analog waveform exhibiting periodic impulses exceeding the average amplitude thereof as the tool wears.  A micro-processor controlled variable gain amplification network is utilized to normalize the average waveform amplitude to a fixed level.  During machine operation, impulses are de-tected by comparing the sensor waveform to a programmable selected ratio of the normalized level.  When a given number of successive impulses are received the microprocessor generates a warning signal which may be used to retract the tool.  An adaptive mode is disclosed wherein the sensor waveform throughout the course of the machining operation is repetitively normalized to adjust for different sensor waveform amplitudes.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided for measuring and controlling the level of an elevated temperature liquid in a container.  The electrical voltage signal outputs of a plurality of temperature sensing devices at spaced elevations on the container are con-verted to digital form.  The converted signals are periodically scanned in elevation sequence.  A determination is made from the scanned signals of the location of the uppermost sensing means having a converted signal value of sufficient magnitude to indicate a temperature in the wall below the level of liquid in the container.  Then a fraction, F, of the spacing between the sensing means, n, and the next above sensing means, n-l, is cal-culated as a function of the converted signal value, Sn-l.  The measured level in the container is calculated as a function of, n, and, F, with respect to their location on the container.  Finally, the rate of addition and withdrawal of liquid to and from the container is controlled based on the measured liquid level in the container.

Abstract: A PERSISTENT CURRENT SWITCH FOR HIGH                 ENERGY SUPERCONDUCTIVE SOLENOIDS                      ABSTRACT OF THE DISCLOSURE       Electrical switches used in conjunction with high energy superconductive windings must be able to quickly absorb large amounts of electrical energy since switching of the superconducting current is accomplished by means of transition to the resistive state in the switch portion of the superconducting current loop.          Furthermore, to minimize the heat generated during the transition to the resistive state, the switch itself should exhibit a relatively high resistance while at the same time exhibiting a low external magnetic field.          The switch should also exhibit minimal stray magnetic fields, especially in those applications requiring field uniformity.  These objectives are achieved in a persistent current switch which includes a length of superconductive material disposed in a compact, thermally insulated volume which also includes a mechanism for heating at least a portion of the superconductive conductor in the switch in order to return it to its resistive state.  Furthermore, there is included a mass of thermally conductive material within the volume which is in thermal contact with at least a substantial portion of the superconductive conductor to mitigate the effects of hot spots occurring within the switch.
