Abstract: ABSTRACT OF THE DISCLOSURE     Method and apparatus are set forth for forming a substantially enclosed longitudinal path along the cutting surface of a workpiece and substantially enclosing a cutting wire of electrical discharge machining equipment so as to confine and direct dielectric fluid supplied thereto along such cutting wire to flush out eroded particles formed during the cutting of a slot in the surface of the workpiece.          Furthermore, a method of improving the cutting rate and depth of cut of multiple slots produced within a workpiece is disclosed which includes the formation of initial counter slots in the surface of the workpiece having a width sub-stantially larger than the width of the desired functional slots to be formed in said workpiece.  The invention is of particular interest in the formation of long thin slots of accurate configuration such as in ceramic honeycomb structures which require accurately parallel sidewalls which must be burr-free and have consistent surface finish.  In particular, it achieves good repeatability by providing consistently identical channels or slots in work pieces.

Abstract: D-5,713 COMBINED CLOSED LOOP AND ANTICIPATING         KNOCK LIMITING SPARK TIMING SYSTEM          Abstract of the Disclosure A closed loop knock control system integrates a knock signal comprising knock intensity indicating knock pulses from an engine mounted knock sensor into a retard voltage in an integrating amplifier normally provided with a fixed reference voltage through a series pair of resistors.  The junction of the series pair of resistors is connected through another resistor and a semiconductor switch, when the switch is actuated, to a second constant reference voltage greater in the retard direction than the first.  An open loop knock anticipating system responds to a detected knock anticipating event by actuating the semiconductor switch means for a predetermined time duration to produce a step change in the retard direction for the predetermined time duration in the retard voltage and thus in the spark timing.  If voltage limiting means is provided in the closed loop system for the output of the integrator, the summed combination of the closed and open loop retard voltages is also limited thereby.

Abstract: ABSTRACT OF THE DISCLOSURE      This disclosure improves data processing system integrity by assigning content types to virtual pages and using the assigned content types to enforce special access rules.  The page content types are:   (a) any changeable data and/or any executable instructions (current S/370);  (b) SCP executable instructions and/or unchangeable data (SENC); (c) SCP restrictively change-able data only (system DO); and optionally (d) appli-cation data only (user DO).  Page content type desig-nation is done by providing in each PTE two integrity control flag bits called herein SENC and DO.  In the first embodiment, the SENC and DO bits are separately coded to respectively control access to SENC and system DO page types. In a second embodiment the SENC and DO bits are combinatorially encoded to obtain four types. A new system integrity state, the SCP state, is provided to protect SENC and system DO page usage. The SCP state is initiated by a hardware interrupt, i.e. a swap of PSWs, and exists only as long as the CPU is fetching instruc-tions from SENC pages.  The following new program interrupts are provided to identify when the CPU tries: (1) to execute an instruction fetched from a SENC page while the system is not in the SCP (2) to execute an instruction fetched from a system or application DO page; or (3) to store data into a system DO page using an instruction not fetched from a SENC page.  Also while in the SCP state, key zero users are forced to change their access key, whenever necessary, to match the storage key of any page frame prior to changing it.

Abstract: Abstract of the Disclosure Position-Fixing System Several satellites serving as reference stations (Sj) for a user revolve about the earth in different orbits. At least four reference stations must be within sight of a user sta-tion (N) at the same time. The user station measures the ranges to at least four reference stations by one-way rang-ing. From these ranges and the positions of the reference stations, which are transmitted as data words, the user station determines its position.            To determine the positions of the reference stations, the ranges from the respective reference station to at least three ground stations (Bi) are measured by two-way rang-ing. From these ranges and the known positions of the ground stations, the position of the reference station is obtained.            The interrogation signals of all reference stations contain the same basic signal (Ks), which represents a pseudoran-dom code. The reply signals of the ground stations contain differently coded signals (KBi), so that the ground sta-tions are identifiable with the aid of the codes assigned to them.            If the interrogation and reply signals contain the times of transmission (tj) and arrival (ti), respectively, of the interrogation signal, and the signal transit times are measured, the clocks of the reference stations and of the ground stations can be synchronized.

Abstract: ABSTRACT OF THE DISCLOSURE           A pilot signal detecting circuit for use in an stereo receiver capable of receiving and demodulating AM stereo signals broadcast according to any of several different AM stereo modulation methods, in which the particular method employed in broadcasting the AM stereo signals is determined by detecting the individual pilot signal and providing an indication of the particular method employed in modulating the broadcast AM stereo signal.          Replicas of each of the different pilot signal frequencies in each of the different AM stereo modulation systems are generated and a signal containing the pilot signal is extracted from the demodulated received AM stereo signal.          The replicas are compared with the extracted pilot signal to determine the identity of the AM stereo modulation system employed in the received AM stereo signal.  A phase-locked-loop is employed to extract the pilot signal from the received signal and a synchronous detector and envelope detector are employed to demodulate the left and right channel stereo signals from the received AM stereo signal.  Comparison of the replica and the received pilot signal is performed in identical phase detectors which receive a corresponding replica of the pilot signal produced by another phase-locked-loop and a frequency divider.

Abstract: ABSTRACT OF THE DISCLOSURE         A   magnetic   device  for   nondestructively inspecting elongated objects such as wire cables and the like, for loss of metallic cross-section due to abrasion and corrosion and internal defects as magnets which induce a saturated magnetic field axially through a short section of the cable as the device and the cable move relative to one another.  A sensing coil located in close proximity to the cable between the magnetic poles detects small changes in leakage flux at the surface of the cable in the saturated condition.   The sensed flux changes are applied to an integrator to measure the net variation in flux and correspondingly the total change in cross section.  Multiple sense coils mounted on core pieces conforming to the external surface of the cable ensure complete continuity of the inspection process and allow the magnetic device to be installed and removed at intermediate stations along the cable.
