Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for supporting and positioning the human anatomy.  A plurality of support modules is secured to a  chassis.    Each  support  module  has  at  least  one  anatomy conforming support element for contact with a portion of the human anatomy and a deformable member or segment that positions the anatomy conforming support element with respect to both the human anatomy and the chassis.   In one embodiment, the support module  is first formed from a generally planar sheet member having  at  least  two  supporting  elements  separated  by  a relatively  deformable  portion  of  the  planar  sheet  member.          Thereafter, the sheet member is bent into a preform to conform to the general shape of the human anatomy.  At least a part of this bending occurs about a predetermined axis  (or axes) that lies (or lie) in the relatively deformable portion (or portions) of the sheet member.  Further bending of the preform along each predetermined bending axis can be employed to custom fit the preformed  support  module  to  the  specific  anatomy  of  the individual.   Such bending takes place about the predetermined bending axis because the relatively deformable portion of the sheet  member  deforms  before  the  supporting  element(s)  even though the bending force is applied in a non-normal, but not parallel direction to the bending axis.  The axis of bending is related to the human anatomy and to the chassis.  Preferably, in the case  of  plural  bending  axes,  the  relative  degree  of bendability of the deformable portions is controlled to achieve bending about each axis without affecting the previously bent portions of  the support module.   In another embodiment,  the apparatus  is  not  custom  fit  but  conforms  to  a  variety  of different human  anatomies.   In this embodiment,  the support module has at least one anatomy conforming support element for contact with a portion of the human anatomy and a yieldable and resilient deformable member  or  segment that flexes about the said axis to position the supporting element with respect to both  the  human  anatomy  and  the  chassis  in  response  to the pressure exerted upon the support module by the particular user.

Abstract: ABSTRACT       METHOD AND APPARATUS FOR MEASURING FLUID FLOW            A fluid flow meter and, more especially, an airflow meter having fast response and very high resolution uses piezoelectric transducers operating near resonance to pass ultrasonic signals upstream and downstream alternately in a flow passage. Transmission signals continue longer than the propagation time to the receiver so that the phase of the received signals can be compared to the transmission signals.  The difference of upstream and downstream phase differences is a measure of the air velocity while the sum of those phase differences is useful to determine air temperature.  These values along with an air pressure sensor reading are combined to determine mass airflow through the passage.  The acoustic transducers are operated near resonance to optimize signal-to-noise ratio.  Readings from the initial reception period of each transducer are ignored to avoid the effects of ringing of the transducer from each previous transmission cycle and to allow the receive signal to build up resonance with the acoustic signal.

A field coil is provided which includes a separate single turn around each of the SQUID pick-up loops.  The SQUID pick-up loops and the surrounding field coil turns are both located over a hole in a superconducting groundplane.  The SQUID pick-up loops are connected by wide, low inductance transmission lines to remotely located Josephson tunnel junctions.  The signal to be detected is generated locally within one of the SQUID pick-up loops to provide direct coupling of the sample to be measured to the SQUID pick-up loop.  The SQUID tunnel junctions are remotely located from the pick-up loops and are located over a superconducting groundplane.  A resistive balance circuit is provided, as is readout electronics for detecting the state of the SQUID.

Abstract: SAW CARRIER ASSEMBLY FOR FELLER BUNCHER          ABSTRACT OF THE DISCLOSURE            A saw carrier assembly has a loop of saw chain and a powered sprocket to drive the saw chain. The assembly also has a saw chain journalling structure having a rotatable circular periphery cooperating with the saw chain to mount the chain to rotate therewith to reduce friction and to resist sawing forces. The saw journalling structure and sprocket cooperate with a saw support structure so that the chain saw extends as a loop around the sprocket and journalling structure. The journalling structure has a thickness less than the kerf produced by the saw to permit a portion of the saw journalling structure to pass into the kerf with negligible interference therewith. This enables a tree to be cut using a saw journalling structure of slightly less diameter than diameter of the tree where it is cut, and reduces frictional losses normally associated with a fixed chain saw support bar.
