Abstract: Abstract of the Disclosure A retry mechanism facilitates release of a communications path by a device which is either unable to respond to a requested operation or which is unable to do so within a reasonable length of time. The mechanism is easily implemented and has a wide variety of applications, including use in operations requiring a number of transactions on "interlocked" type communications paths to accomplish a given function. It is also particularly useful in facilitating interconnection of communications paths controlled from independent control sources.

The relay has at least one double-throw switch in which a pair of first and second movable contact members are driven to move with respect to a fixed or common contact member disposed therebetween for closing and opening contact operations in cooperation with the fixed contact.  All these contact members are mounted on a contact base such that the fixed contact member is arranged between the first and second contact members.  Also mounted on the contact base is at least one set of common, first, and second terminal lugs which are connected respectively to the fixed, first and second contact members to project downwardly from the base.  The first and second terminal lugs are disposed in generally vertical alignment respectively with the corresponding first and second contact members, while the common terminal lug is disposed out of vertical alignment with the corresponding common contact member so as to be terminal arrangement of a conventional relay of flexure type having the like double-throw switch arrangement so that the above relay can be well compatible therewith.

Abstract: ABSTRACT A sputtering process for depositing amorphous films of semiconducting alloys having a reduced number of localized states is disclosed.  In particular, hydrogenated alloy films free of polyhydrides may be prepared according to the inventive process.  In one application of the process an alloy target is bombarded by separate beams of relatively heavy sputtering ions, such as argon ions, effective in sputtering the target and by passivating ions of a substance effective in passivating localized states in amorphous semiconductor films, such as halogen or hydrogen ions.  In another application, targets of the elemental semiconductors that are the constituents of the alloy of the deposited film are simultaneously bombarded by separate pairs of ion beams.  Each pair of ion beams includes a beam of passivating ions and a beam of sputtering ions.  The products of the sputtering are collected on a remotely located substrate to form a passivated, amorphous alloy film.  In a preferred application, amorphous, hydrogenated alloys of germanium and silicon containing hydrogen predominantly in the form of monohydrides are produced.  Films produced according to the process may be doped and junction structures formed during deposition by adding dopant ions to a beam of passivating ions.

Abstract: Electroviscous liquids A B S T R A C T      The electroviscous suspension is based on a mixture of aqueous silica gel with silicone oil as the liquid phase to which a dispersant is added.   The dispersant consists of amino functional or silicon-functional polysiloxanes having a molecular weight above 800.   The concentration of the dispersant is from 1 to 30% by weight and preferably from 5 to 20% by weight, based on the silica gel particles. Electroviscous suspensions such as these are distinguished by the fact that they are highly compatible with elastomeric materials, non-sedimenting, non-inflammable and physiologic-ally acceptable.   In addition, they are heat- and freeze-resistant over a wide temperature range and are largely unaffected by temperature and pressure in their viscosity.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved axle clamp is provided, particularly for use with composite material leaf springs, to securely fix the position of the leaf spring relative to a wheel axle or other suspension system member.  The axle clamp comprises a rigid clamp base, a resilient wedge insert, a rigid clamp plate, and a resilient cover pad.  The clamp base provides a bottom wall and substantially parallel side walls extending from the bottom wall to form a channel adapted to receive the wedge insert.  The inner surface of at least one side wall of the clamp base fairs from both ends into a channel-widening concavity, preferably at the longitudinal mid-point of the channel.  The wedge insert has a bottom wall and substantially parallel side walls extending from the bottom wall and forming therewith an inner channel adapted to laterally jacket a leaf spring. The outer surface of the wedge insert substantially fills the clamp base channel and, so, provides a convexity adapted to register with the channel-widening concavity of the clamp base.  The clamp plate attaches to the clamp base to clamp the leaf spring between them. The resilient cover pad lies between the clamp plate and the leaf spring. The cover pad and the wedge insert each provides a vertically raised support pad extending laterally across the channel at each end to contact and support the leaf spring.  The resilient material is recessed between the support pads.

Abstract: ABSTRACT A refillable filter-drier assembly for use in a refrigerant line.  the assembly includes a shell or casing which houses a replaceable core having a central bore and which may be a filter, drier or strainer element or any combination thereof.  Refrigerant enters the shell adjacent one end and occupies the space surrounding the core.  The liquid passes inwardly through the core into the central bore and exits the casing from the end opposite from which it enters.  The core is supported in spaced relationship with respect to the casing interior by an annular cage on the outlet end of the core and by an end closure cage on its opposite end.  Both the annular cage and the end closure cage have resilient zingers which grip the core adjacent its opposite ends.  Both the annular cage and the end closure cage also have pluralities of laterally extending lugs which support the core in its spaced relationship within the casing.  The annular cage on the core outlet end also carries a loose-fitting plug-like screen which projects into the central bore of the core.  The core may be unitary or comprised of two or more co-axial, end-to-end sections with an annular intermediate cage between juxtaposed sections.  The intermediate cage will have resilient gripping fingers that grip one of the juxtaposed sections and will also have a plurality of laterally extending lugs which assist in supporting the core in its spaced relationship within the casing.  when a core is spent or otherwise needs replacing, it is removed and the casing is refilled with another core.

Abstract: "DISC-AXIAL MULTIPORT VALVE"              ABSTRACT    A unitary disc-axial multiport valve is capable of accomplishing the simultaneous interconnection of a plurality of conduits in accordance with a previously determined cycle, where any conduit communicates with no more than one other conduit at any one cycle step, or valve index position. The conduits to be interconnected are attached to a hollow stationary body, or stator assembly, which is comprised of two sections, or elements, one being cylindrical in exterior form and the other having a disc-like form with a central opening and being joined to the cylindrical element at one end in a flange-like manner. There are fluid flow paths in a rotating body, or rotor assembly, which is located partially inside the statorassembly, extending through the central opening in the discular element of the stator. The form of the rotor assembly is similar to that of the stator assembly. The rotor assembly assumes various positions according to the cycle steps and distributes fluid flowing into and out of the valve in a different manner in each cycle step. There are spaces between the rotor and stator assemblies which contain sealing means for prevention of leakage and definition of flow passages.
