Title: Environmentally-protective combination burial/shipping/ cremation case
Inventor: MCCLURE WILBUR F
IPC: A61G17/04
Filed: 1994-06-28
Abstract: ABSTRACT    An environmentally-protective body container comprises a utility case section made by the process of blow-molding an extruded thermo-plastic parison into double-walled barriers comprising an inner shell and an outer jacket for purposes of economy, light weight and adequate structural integrity.  Preferably, both the lower section and the upper section or lid of the case are blow-molded, either as separate sections subsequently joined by an extruded plastic hinge or as a single unit with the hinge being formed during the blow-molding process.   The case can be used either as a casket for burial or for cremation.  The same case can also be used as a body shipping container, eliminating the need for body handling where a corpse is placed in the case at one location and then shipped by air and viewed in another location.  The lid may may be full or half-couch to enable viewing either the entire body or only the upper torso.  By selecting an organic thermoplastic which does not create explosive gases during burning and by avoiding use of metallic hardware, the entire case and corpse can be cremated together, leaving little ash or residue.  At least the lower portion of the outer jacket of the case is impervious to liquids, thereby preventing body and embalming fluids from contaminating the adjacent ground water supply in the case of burial.  The impervious outer jacket also prevents outward leakage of fluids during shipment.          Preferably, the outer jackets of both sections are fully impervious to prevent liquids from either leaving or entering the case at any time.  Air injection holes created in the inner shells during the conventional blow-molding process serve a useful purpose in making the inner shell air pervious and thereby providing expansion space for body gases between the jackets and shells.  The air injection holes may also be enlarged from their production size or additional holes may be provided to enable placement of desiccants or other functional materials between the double-walls of the casket.  Use of a double-walled case also enables several other advantages to be achieved.  It allows hand recesses to be formed into the outer jacket and thereby eliminate the need for costly metallic pallbearing hardware.  It also allows forklift truck recesses to be formed in the outer jacket bottom to provide for easier handling by airlines.  The forklift recesses are convenient for lifting and handling the case while at least its top, sides and ends are surrounded by a corrugated air tray. All of these advantages are achievable while maintaining wall thickness uniformity and the resultant minimal use of thermoplastic material inherent in the process of blow-molding.

Title: Software Pay-Per-Use System
Inventor: MICHEL ALAN D
IPC: G09C1/00
Filed: 1994-09-29
Abstract: A pay per use system  for  the  prevention  of  the unauthorized use  of  computer  software.   An encryption program  encodes  original  software  to  produce  secured software.     The  encoding  is  accomplished  by  using cryptographic techniques.  In order to use the software, a user  must  call  a  telephone  number  to  receive  the cryptographic  keys  necessary  to  decrypt the  secured software.  Thus, users must pay for each use of the secured software.  The system allows software developers to freely distribute the secured software.   Copies of the secured software may be freely made, because payment is based on each use of the software not on each copy of the software.

Title: Physical measurement from changes in reactance
Inventor: GUNN COLIN N
IPC: G01B7/02
Filed: 1995-01-27
Abstract: An apparatus and method for centre finding and physical proximity measurement, the apparatus including a reactance controlled signal source for producing a measurement signal having  a  measurement  signal  frequency  dependent  upon reactance and a probe tip connected to the signal source. The probe tip is operable to receive the measurement signal while presenting a measurement reactance to the signal source, the measurement reactance being due to coupling of the probe tip with a workpiece adjacent the probe tip and the measurement reactance varying in accordance with the physical proximity of the probe tip to the workpiece.  The measurement reactance causes the signal source to vary the measurement signal frequency according to the proximity of the probe tip to the workpiece.   The measurement signal frequency is sufficiently high to enable the measurement signal to be radiated by the probe tip for reception by a remote receiver.   The probe is therefore rotatable and operable to provide continuous proximity information while rotating.
