Abstract: ABSTRACT         This invention comprises a fusible resistor in a solid astate relay comprising two solid state switches con-nected in parallel with each other, but in series with a load and a source of current.  When the first of the two switches is switched on, the second switch also switches on, and con-ducts, supplying sufficient current to the load, thus reduc-ing the voltage across both switches to that of the voltage drop across the second switch.  Should the second switch fall to become turned on When the first switch is turned on, there will be a higher voltage across the first switch (and the components in series with it, if any) causing excessive current to flow through the first switch, resulting in its overheating and possibly fire, particularly if the switch is encapsulated.  By providing a fusible resistor in the circuit of the first switch, the fusible resistor will open at such time and disconnect the first switch from the cir-cult, preventing a possible fire or possible damage to adjacent equipment.

Abstract: FIELD EFFECT TRANSISTOR WITH         SELF-ALIGNED GATE           Abstract of the Disclosure A field effect transistor (FET) with a unique gate structure is disclosed wherein the polycrystalline sili-con (polysilicon) gate is self-aligned on its ends with respect to the conductive source and drain regions, and is self aligned on its sides with respect to the non-con-ductive field isolation regions.  The boundaries of these conductive and nonconductive regions determine the bound-aries of the channel region of the FET.  This double self-alignment feature results in a polysilicon gate, the lateral dimensions and location of which correlate directly with the lateral dimensions and location of the channel region of the FET.  The unique gate fabrication technique employed according to the present invention comprises delineating lithographic patterns twice in the same polysilicon layer using the same oxidation barrier masking layer; whereby the first lithographic pattern delineates the FET device regions, and the next lithographic pattern forms the gate regions wherever the two patterns cross each other (i.e., wherever they delineate a common area).

Abstract: ABSTRACT:             A non-recursive discrete filter for simultaneously realizing for example two band-pass filter characteristics starting from a given lowpass transfer characteristic, wherein one bandpass filter has an in-phase transfer characteristic and the other filter the quadrature transfer characteristic of this in-phase filter. The central frequency of these filters is fo and the output sampling frequency is fs =8fo.          This discrete filter comprises multiplying means in which input signal samples x(n) are modified by an associated filter coefficient a(i) for generating modified input signal samples z(n,i) = a(i)x(n-i). The coefficients a(i) are the same for both transfer characteristics and are given by: a(i) = h1(i)  ¦   cos (.pi.i/4)  ¦     for cos(.pi.i/4) ? 0 a(i) = h1(i)  ¦   sin (.pi.i/4)  ¦     for cos(.pi.i/4) = 0 wherein h1(i) represents the discrete impulse response of the lowpass filter.           To realize the in-phase transfer characteristic the samples z(n,i) are thereafter multiplied by a factor sgn[cos (.pi.i/4)] and the products thus obtained are accumulated.          This results in the output signal sample   To realize the quadrature transfer characteristic the samples z(n,i) are thereafter multiplied by a factor sgn[sin(.pi.i/4)] and the products thus obtained are accumulated.

Abstract: ABSTRACT OF THE DISCLOSURE           A rotatable knob assembly having a knob easily mounted to the mounting section of an operating member, with the mounting section having two adjacent parts with a first part having a generally elliptical cross section and the other part having a generally circular cross section and with the knob having an open-ended cavity and an upstanding ridge on the inner surface of the cavity surrounding the wall which is of generally the same perimetrical length as the generally equal perimetrical lengths of the two parts of the mounting section.  The knob is formed of a material which is capable of being distorted whereby placement of the knob on the mounting section by relative insertion of the mounting section into the cavity causes distortion of the locking ring to pass over the generally elliptical cross section part and the locking ring then returns to its normal shape to engage against the generally circular part of the mounting section and to lock behind the elliptical section.

Abstract: Abstract of the Disclosure The invention concerns a rubber hose including an insert or core made of a spiral system of fibre-reinforced synthetic resin and a circular-woven or helically developed insert or core system, which hose is capable of withstanding the combined effect of simultaneously acting stress forces of internal and/or external pressure or vacuum and axial tensile and/or torsion-al loads.  The invention further concerns a process for the manufacture of such a hose.  With the accelerating progress of technical development, in-creasingly a demand arises for hoses capable of bearing very large combined stress loads, such as high external pressure, tensile load, torque and vacuum which in many cases act simultaneously.  Such hoses are required e.g. for deep-sea drilling, as well as for supply pipe lines, flexible deep-sea con-duits or cables, flexible boring bars and for flexible pipe line systems for pile-driving hammers.  Known hoses comprising internal stiffening helically wound cores are not suitable for bearing very large stress loads, due to the fact that coil winding at a low pitch angle of the steel wire forming the stiffening system is very difficult when a certain limit in the cross-section of the wire is exceeded.

Abstract: ABSTRACT OF THE DISCLOSURE      A full rotational freedom, substantially zero friction electrical contact assembly for conducting electrical currents between relatively rotatable members of sensitive instruments such as gyroscopic devices and the like and a method of and apparatus for the assembly thereof is disclosed.          Each electrical transfer unit of the assembly comprises a pair of coaxial, concentric, coplanar, continuous, concave conductor rings, one mounted on a relatively fixed member and the other mounted on the rotatable member, the relative diameters of the rings providing a substantial annular radial gap therebetween.  A resilient, electrically conducting, continuous, filamentary loop is disposed in the radial gap such that its generally flat outside surface contacts and rolls on the concave surfaces of the concentric conductor rings.          The loop/conductor interface provides self-capturing and retaining forces to accommodate any misalignment between the rings and movements of the loop within the radial gap in a vibratory and/or shock environment all without producing frictional torques on the rotatable member.  The critical dimensional parameters of the concave conductor ring surface and the loop, particularly its free (unassembled) diameter relative to the radial distance between the concentric conductors, its thickness and width, and its material characteristics are selected so as to provide: substantially zero friction and coupling torque on the rotatable member; maximum retention capability; maximum current conduction; and maximum life.  In another aspect of the invention, the assembly is designed such that the loops may be readily assembled without deforming, overstressing or damaging the same while permitting loops of various acceptable free diameters and hence preloads to be employed, and furthermore, the design of the assembly allows the selection of ring concavities of various depths to satisfy the vibratory and shock environment of various applications.

Abstract: Abstract A transceiver (transmitter-receiver) for high frequency data pulse signals is connected to a coaxial cable transmission line through a distributed delay line which has an impedance equal in value to the characteristic impedance of the coaxial cable trans-mission line.  The transceiver transmitting and receiving circuits are tapped into the transmission line and form a part of the dis-tributed delay line.  When not in the transmitting mode, the trans-mitter circuit appears as a reactive element of the distributed delay line and thereby introduces minimum loss or reflection into the transmission line.  The transmission line can serve as a trunk line for a number of transceivers by permitting virtually unre-stricted multipoint connections to the line.
