Abstract: ABSTRACT OF THE DISCLOSURE         In a video tape recorder having a tape on which are recorded "0" and "1" binary coded bits of a pulse width modulated signal as for identifying frames of a video signal also re-corded on the tape, the tape being advanced past a head detecting the pulse width modulated signal at speeds variable with the fast forward, normal and slow motion mode of operation of the recorder so as to change the bit frequency of the pulse width modulated signal in correspondence with the speed of the tape, a circuit which demodulates the "0" and "1" bits of the detected pulse width modulated signal by comparing the coded pulse width of each succeeding bit (Bi+1) with the width of the preceeding bit (Bi) to make the demodulation substan-tially independent of the bit frequency and the corresponding speed of the tape so that the circuit operates in each mode of recorder operation.  In the preferred embodiment of the circuit, each bit is quantized into periodic pulses which correspond in number to the width of the bit.  The number of pulses corresponding to the pulse widths of successive bits are then digitally compared in a comparator to obtain a two-level discrimination signal.  More particularly, only selected higher value digits of the pulse numbers are compared to simplify the comparison and the com-parator changes the level of the discrimination signal only during a preselected portion of each bit relative to the preceeding bit to assure accurate demodulation.  The preferred circuit also has a circuit for deriving an edge pulse signal from the coded pulse width of each bit and a logic circuit operating on the edge pulse signal and the dis-crimination signal from the comparator for providing a signal corresponding only to bits or the one value, for example the "1" bits.

Abstract: ABSTRACT OF THE DISCLOSURE     A property such as moisture content in a sheet of material such as paper that both absorbs and strongly scatters infrared radiation is measured by passing the sheet through the central region of a substantially spherical cavity formed between a pair of concave mirror-surfaced, specularly reflecting bodies that are spaced apart to form a pass gap of sufficient width to allow substantially free movement of the sheet therethrough while sub-stantially enclosing a first portion of the sheet on both sides.          A spot of infrared radiation is projected onto one side of the sheet in the center of the cavity to illuminate a second portion of the sheet included within and substantially smaller than the enclosed first portion.  Thus infrared radiation scattered or transmitted by the second portion is reflected from the mirror-surfaced bodies and directed back to the second portion sub-stantially within the area of the sheet defined by the spot.          The relative sizes of the first and second portions in relation to the width of the pass gap determine the relative quantities of radiation being retained in the cavity and escaping through the pass gap.  On the opposite side of the sheet relative quanti-ties of both the projected radiation transmitted by the sheet and radiation reflected from the reflective bodies are detected so as to produce an output response indicative of the measured property.  The relative quantities of the retained and escaping radiation and the detected transmitted and reflected radiation are selected to make the output response substantially indepen-dent of changes in other properties affecting the scattering power of the sheet material, such as the bone-dry weight or composition of paper.     ***************************

Abstract: ABSTRACT OF THE DISCLOSURE       A micro-miniature stepping motor suitable for driving the gear works of an electronic watch wherein low-frequency timing impulses derived from a high-frequency time base are applied to the stator coil of the motor to cause the rotor thereof to index ninety degrees in response to each impulse.  The rotor includes a square rotor plate and a stator plate parallel thereto, a shaft secured to the center of the rotor plate extending through a central opening in the stator plate.  Mounted on the underside of the rotor plate at the corners thereof are four permanent magnet blocks with their poles in mutual opposition to form a magnetic circuit between the rotor stator plates whose lines of flux bridge the air gap there-between.  The stator plate has a generally square formation whereby the magnet blocks on the rotor, in the absence of a torque-producing force, seek to orient themselves to a stable position of minimum reluctance.  In this position, each block is proximate to a respective corner of the stator plate, there being a series of four such stable positions which are ninety degrees apart.  The stator coil has a pancake formation and is interposed in the air gap, whereby when an impulse is applied to the coil, the resultant torque displaces the rotor to cause it to index to the next stable position.

Abstract: PHX.8488 ABSTRACT            The invention relates to a memory with mag-netic domains which can be driven along at least one co-herent path. The drive along a first path section of the path is effected by a magnetic field which periodically varies in the time, for example, a rotary magnetic field which is continuously oriented in the plane of the magne-tizable plate with the domains. This first path section can be composed of T-I elements or chevrons of permalloy.          This method of driving offers the advantage that the dissipation per period of the domain guide structure is very low. The drive along a second path section of the path is effected by means of a current conductor which is provided on the magnetizable plate with the domains and which is shaped, for example, as a meander, under the control of a periodic current therein. This drive offers the advantage that the achievable propagation frequency is very high. The advantages of both kinds of drive can be combined in that the first and the second path section are interconnected, it being possible to transfer the domains or their information in at least one direction; it is alternatively possible to form a logic function between domains already present in the first and the second path section. The two drives can operate at mutually different frequencies and/or inter-mittently. Thus, input and output functions can be very quickly realized. The overall dissipation remains low, because only part of the domain guide structure comprises a current conductor and this current conductor is usually activated only at intervals. Furthermore, a variety of functions can be realized by the combination of two in-dependent drive mechanisms.

Abstract: SEMI-CONDUCTIVE STRESS RELIEF SHIELD FOR HIGH VOLTAGE EQUIPMENT Abstract: A semi-conductive coating is applied on the outside diameter of a cake of arc extinguishing material positioned within the interior of a high voltage fuse, and the semi-conductive coating is electrically connected to one end ferrule of the fuse to form an electrical stress shield. Upon operation of the fuse, dielectric stress between the end ferrule and the metal fitting at the other end of the fuse tends to be concentrated by the semi-conductive coating within the insulative material of the fuse housing. Without the semi-conductive stress shield, dielectric stress at the edge of the outside fuse fittings may cause a corona discharge external to the fuse adjacent to the external fitting, which may trigger an external flashover along the length of the entire fuse.

Abstract: ADAPTIVE ERROR ENCODING IN MULTIPLE ACCESS SYSTEMS   Abstract Of The Disclosure In a time division multiple access (TDMA) system, for "multi-path" data communication via satellite repeater, the form of transmitted data is varied adaptively to main-tain error-free transmission under varying noise condi-tions.  Adjustments are made on a path selective and chan-nel selective basis to protect only the most vulnerable data in specific transmission paths experiencing noise deterioration.  Accordingly any multi-channel burst may contain channels of data in both protected and unprotec-ted forms.  A predetermined portion of each channel con-taining data in unprotected format is used explicitly to designate the destination of the accompanying data and implicitly to distinguish the data format as unprotected. In protected format data including error protective cod-ing is transmitted in two contiguous channels along with information in the first channel explicitly distinguish-ing the protected format  This format-distinguishing information occupies the space allotted in the unprotec-ted format for designating the data destination.  The destination of protectively encoded data is explicitly designated in a separate predetermined space in the asso-ciated double-channel slot.
