Title: System for producing tubes
Inventor: FABIAN ELLIS
IPC: B29C48/90
Filed: 1986-12-12
Granted: 1991-07-02
Abstract: ABSTRACT       A process and apparatus for preparing seamless, creaseless, pliable, thin-walled tubes involves extruding a continuous moving tube of polymeric film material from a die into the ambient atmosphere.  The tube is radially stretched over a sizing disk as the polymeric film material emerges from the die.  A pillow of pressurizing air is maintained within the tube in the region between the die and the sizing disk.  The tube is longitudinally stretched.  The downstream free end of the tube is maintained open to the ambient atmosphere and free of creases.  The tube is severed while maintaining the cross-sectional shape of the tube free of creases and while the tube is in motion.  The result is at least one tube segment having a right cylinder configuration substantially free of creases.

Title: Automated operator assistance calls with voice processing
Inventor: DAUDELIN ABRAHAM N

Granted: 1991-04-02
Abstract: AUTOMATED OPERATOR ASSISTANCE CALLS               WITH VOICE PROCESSING                       Abstract A method and apparatus for identifying the class of an operator assistance call in order to reduce the operator work time for serving such a call   A customer dials 0 or dials 0 plus a directory number and is connected to a program controlled operator assistance system or switch.  The switch initially connects the calling customer to a voice processing unit and prompts the customer to speak a command or key a command code. The command or command code is recognized and used to direct the flow of the control program to selectively defer a connection to an operator position.  For example, for person-to-person calls, the operator position is only connected after the called customer terminal answers.  Advantageously, such a method and apparatus substantially reduces operator work time for broad classes of frequently used operator assistance services.

Title: Method and inner sole for warming the foot of the wearer of footwear
Inventor: ZELLWEGER MAX
IPC: A43B7/02
Filed: 1987-06-15
Granted: 1993-08-03
Abstract: ABSTRACT         In an inner sole (1) for a shoe, hollow members (3 - 6) filled with a fluid are provided, each of these members being designed as a tube (7) with closed ends (8, 9).  A flow restrictor (10) is installed in the middle region of each tube (7) and divides the tubes (7) into part-cavities  (11, 12).  The flow restrictor (10) possesses restricting channels (21) through which the part-cavities (11, 12) are connected to one another. As a result of the fact that a pressure is exerted al-ternately in the heel region and in the toe region during walking, the fluid introduced into the part-cavities (11, 12) is pressed backwards and forwards through the restricting channels (21), heat being generated which is released to the environment and thereby warms the foot.

Title: Purification system
Inventor: CSABAI JULIUS S
IPC: F24C15/20
Filed: 1987-06-30
Granted: 1991-12-10
Abstract: ABSTRACT           The   present   invention   relates   to   a   fume purification system used  in conjunction  with  food cooking equipment.  The fumes which are generated during cooking pass through a plurarity of  filter balls  washed by  an oxidizing liquid which  removes the greasy contaminants  from the said fumes.  A cooling coil is also used in  conjunction with the filter balls  to accelerate the condensation of the fumes. If required, a charcoal filter is placed before the purified air is returned to the atmosphere or recirculated in the system.

Title: Method for the treatment of sewage and other impure water
Inventor: CONNAUGHTON NOEL
IPC: C02F1/52
Filed: 1987-08-04
Granted: 1995-02-21
Abstract: A method is provided herein for the treatment of sewage or other impure water.  The method includes adding to the sewage or other impure water in a mixing zone, all three individually but no more than two premixed together of the following: (a) an inorganic coagulant, (b) an anionic polymer, and (c) a cationic polymer, with intimate mixing of the added chemicals with the sewage or other impure water, with the proviso that (d) the inorganic coagulant, either alone or with the anionic polymer or the cationic polymer, cannot be added last; and (e) the anionic polymer and the cationic polymer cannot be premixed and added together. This provides chemically-treated effluent having large, compact, firmly-bonded, substantially-shear resistant and rapidly-separatable flocs therein. The flocs are separated from the liquid in a separating zone. Treated effluent is then removed from the separating zone.  A predetermined amount of the treated effluent is then recycled back e.g. to the mixing zone, or another location determined by site trials.

Title: Method and apparatus for improving the resolution of digital signals
Inventor: HARTNACK WOLFGANG
IPC: H04N19/60
Filed: 1988-08-22
Granted: 1994-06-07
Abstract: Abstract A method and apparatus for the improvement of the resolution of digital signals.  In digital TV signals which are transformed into a selected frequency range, irregularities in the pattern of the reproduced video signals occur because of rounding off errors, when the number of places is reduced during calculation of the coefficients.  This is remedied by increasing the coefficients of the transformed signal values following at least one first coefficient, for example a uniform component, and reducing them again before inverse transformation.  This invention can be employed in digital systems using block processing in which, because of a limited number of bits, a rounding off of the transmitted spectral coefficients is performed in the calculation.

Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE    A  wellhead  assembly  has  a  metal  seal  that accommodates misalignment between casing and the bore of the  wellhead housing.    The metal  seal  assembly includes a metal seal ring and a wedge ring.  The seal ring has a cylindrical inner wall and a conical outer wall.  The centerlines of the inner and outer walls are offset with respect to each other,  making the ring eccentric.   Similarly, the wedge ring has a conical inner wall and an outer wall.   Its inner and outer walls are offset with respect to each other.  The rings can be rotated relative to each other and to the casing to coincide the axis of the outer wall of the wedge ring with the axis of the wellhead housing bore.   The inner wall of the seal ring has protruding bands which deform as a result of the softness of the metal to enhance sealing.
