Abstract: TITLE          Dual-Rotary Union, Rotational Isolation Adapter ABSTRACT OF THE DISCLOSURE         A dual-rotary union, rotational isolation adapter according to the teachings of the present invention is dis-closed bridging between a rotary union in fluid communication with a source of fluid pressure and a rotation control ap-paratus portion rotatable with respect to a shaft.  In the present invention, an adapter body is rotatably and remove-ably secured to the end of the shaft.  In its most preferred form, the adapter body is rotatably mounted by a pin thread-ably received in the end of the shaft and rotatably mounted by a bearing received within a first cavity formed in the adapter body.  In its most preferred form, the rotary union is received within a second cavity formed in the adapter body opposite the first cavity.  Thus, the adapter body is rotatable with respect to and rotatably isolated from the source of fluid pressure by the rotary union.  Additionally, the adapter body is simultaneously rotatable with respect to and rotatably isolated from the shaft by the bearing ro-tatably mounting the shaft securement pin.  Fluid communi-cation can then be provided between the rotational control apparatus portion and the rotary union for activating the rotational control apparatus portion.  Thus, the body por-tion rotates with the rotational control apparatus portion and is rotatably independent from the shaft and the source of fluid pressure.

Abstract: Abstract of the Disclosure A box-like frame member is formed by deforming the sides of a tubular blank inwardly to provide it with concavely recessed portions in areas corresponding to generally opposing flat surfaces of the product. The deformed blank is expanded, under internally applied fluid pressure, within a sectional die which has its die cavity preferably no more than about 5% larger than the circumference of the blank, to avoid weakening, cracking or yielding of the blank through excessive circumferential expansion. The inward deformation of the side walls permits the blank to be confined within the sectional die without sections of the die pinching the blank on closing of the die, allows for substantially uniform expansion of the blank toward the box-like section and permits the intermediate, deformed blank and the final product to be formed with a smoothly continuous cross-sectional profile, avoiding stress concentrations in the forming procedure and in the final product which can impair the mechanical strength of the product. The tubular blank may be bent into a complex configuration, preferably before inward deformation of its side walls.

Abstract: ABSTRACT OF THE DISCLOSURE   A  data  processing  system  includes  a  plurality  of units which are coupled to transfer  requests  including data, command and integrity signals between units over a system bus during allocated bus transfer cycles.   Each unit  includes   response  apparatus for   acknowledging requests received from other units.  Each of a number of units  further  includes  retry  apparatus  and  checking apparatus  for  verifying  that  all  of  the  parts  of  a request received from such unit over the bus are valid.          When  less  than  all  of  the  parts  of  the  request  are detected as valid, the receiving unit does not accept the request   and   inhibits   its   response  apparatus   from generating a response.   This prevents damage to system integrity and permits each unit with retry apparatus to retry the request during a subsequent bus transfer cycle.
