Abstract: ABSTRACT OF THE DISCLOSURE            An electromagnetic rotary motor including a stator, a rotor and an electronic control arrangement for inducing an electromagnetic field.   The stator includes a permanent magnet having pole faces that define a gap between them with a generally uniform magnet flux density thereacross.  The gap has an entrance section, and exit section and a generally curved longitudinal path extending from the entrance section to the exit section around a transverse axis.   The magnetic flux density changes as one moves from the entrance section to the exit section as a function of arc degree position around the transverse axis.   The rotor includes a predetermined number of permanent magnets disposed radially outwardly from the rotor axis.   These rotor magnets are disposed substantially within the gap and the magnetic field of each rotor magnet interacts with the magnetic filed of the stator magnets through repulsion or attraction.   The electronic control arrangement induces an electromagnetic filed that interacts with a magnetic filed of a rotor magnet.

Abstract: CRASH SURVIVABLE SOLID STATE MEMORY FOR   AIRCRAFT FLIGHT DATA RECORDER SYSTEMS      Abstract Of The Disclosure A crash survivable memory unit for a aircraft night data recorder system is disclosed wherein an electronically erasable solid state memory for storing the night data And a memory controller circuit are housed in a penetration resistant, thermally insulated enclosure. Power dissipation within the insulated enclosure is minimized by an external switching circuit that applys operating potential to the solid state memory only when data are being transferred to and from the memory circuit. A data protection circuit, located within the insulated enclosure inhibits memory write and erase operations whenever the system operating potential falls below a predetermined level. In continuously storing flight data, the oldest stored data is overwritten with newly arriving night data and the memory controller maintains an erased boundary that defines the beginning and end of the recorded data. A power monitor circuit, located outside the insulated enclosure, resets the memory controller to the erased boundary following a power interruption. A dedicated portion of the memory space is utilized to store the address of faulty memory locations (detected during the data storage sequence) and stores the beginning and ending memory address of selected portions of the data record. The memory controller is sequenced to skip both the faulty memory locations and memory storage locations associated with the selected portions of the data record when new flight data is being stored.

Abstract: Abstract of the Disclosure A  digital  acquisition  system  includes  a  high-speed  sampling gate with analog memory for sampling input  signals.  The  samples are converted to digital representations  and stored  in a digital memory.  The digital representations are selectively recalled from the digital memory and fed back as estimators to the sampling gate's  analog memory.  Since the estimators are essentially the previous samples for each point of a given waveform, the stored waveform converges to the input  waveform  very  quickly,  facilitating  accurate waveform replication.  Embodiments for both sequential sampling and pseudo-random sampling are provided. Oper-ational techniques of the digital acquisition system include noise reduction, loop gain determination, adap-tive filtering and signal averaging.

Abstract: ABSTRACT STEP AND REPEAT ELECTRON IMAGE PROJECTOR. A step-and-repeat electron image projector for transferring mask patterns repeatedly from a photoemissive cathode reticle (i) onto a target (3) with high resolution capabilities.  Accelerated by a uniform electric field E and focussed by a uniform magnetic field H a patterned electron beam is projected from the reticle (1) onto an area of the target with unity magnification.  The electric field E is established between the cathode reticle and an electron permeable anode grid (2) situated between the cathode reticle and the target.  Alignment of the beam and the target is effected by detecting electrons backscattered from reference markers 30 on the target, a backscattered electron detector (D) being located between the grid and the target. After exposing one area, the target is moved stepwise on an X-Y table (100) to expose an adjacent area, this procedure being repeated until the whole target has been exposed.

Abstract: A B S T R A C T      The subject of the present invention is a continuous process for the preparation of water-free potassium tert.-butoxide from aqueous potassium hydroxide and tert.-butyl alcohol.   The reaction takes place in a distillation column filled with filler bodies.   The reaction water separating out as well as the water introduced through the starting materials is distilled off at the head of the column with the simultaneous use of a carrier agent.  An alcoholic solution of the potassium tert.-butoxide which is withdrawn and then in known manner worked up for isolation of the water free salt collects in the sump of the column.   The tert.-butyl alcohol is employed in excess, with the amount being so measured that a 10 to 18% by weight solution of the desired potassium salt in tert.-butyl alcohol is present in the sump of the column.   The amount of the tert.-butyl alcohol is so chosen together with the amount of the carrier agent employed that the content of tert.-butyl alcohol in the gas mixture located in the interior of the column lies between 50 and 90% by weight.   The sump of the column is kept throughout at boiling temperature.   Under these conditions, there is drawn off at the head of the column a gas mixture which consists of 20 to 50% by weight of the tert.-butyl alcohol and 50 to 80% by weight of the carrier agent and contains the steam originating in the reaction as well as the water brought in.   The temperature at the head of the column lies, according to the invention, between 65 and 75°C.  Cyclohexane or hexane is employed according to the invention as carrier agent.

Abstract: A B S T R A C T     Fluoropolymer containing coatings are applied to substrates, preferably textile substrates, to obtain com-posites which are flexible and not brittle, and which exhibit a low coefficient of friction, good wear resistance and excellent release properties.  This invention comprises the technique of initially coating a flexible substrate, such as glass fabric or a metal mesh, with a fluoropolymer, which serves to prevent cracking upon flexing.  The precoated sub-strate is thereafter coated with a blend of a hard polymer and a fluoropolymer which adheres well to the pre-coated intermediate substrate.  Significantly, the composites of the invention are flexible, yet possess the wear resistance of the hard polymer component as well as the frictional and release characteristics of the fluoropolymer components.
