Title: Structure for electrically heatable catalytic core
Inventor: WHITTENBERGER WILLIAM A
IPC: B01J35/00
Filed: 1991-08-29
Abstract: ABSTRACT         There is provided an improved electrically heatable core for an electrically heatable catalytic converter.  The core is characterized by corrugated thin metal strips and flat thin metal strips in alternating relation with each other and secured to an electrically conductive central core or tube.  Alternating with the corrugated thin metal strips and the flat thin metal strips are areas of brazing metal in an axially staggered pattern.          These strips are spirally wound and fused to braze them together in a unified monolith.  A retainer shell is supplied to hold the monolith together.   The core is placed in a housing fitted with insulated means for conducting electric current to the monolith to effect heating.  The housing is then inserted in an exhaust line where it is effective to control start-up pollution  and where the monolith is constrained against telescoping.

Title: Blood flow measuring apparatus
Inventor: LIENHARD BRIGIT
IPC: A61B5/276
Filed: 1991-10-09
Abstract: ABSTRACT OF THE DISCLOSURE     The blood flow measuring apparatus comprises at least three  electrodes,  namely,  a  measuring  electrode,  reference electrode and an active neutral electrode, which are implanted at a predetermined tissue region.  The signals of the measuring electrode and the reference electrode are delivered by input lines to a current and voltage isolated differential amplifier, the output of which is connected with a central unit controlling further instruments.     What is important for the measuring accuracy of the blood flow measuring apparatus is an opposite feedback of external spurious fields which couple-in spurious potentials into the tissue and the shields of the input lines of the  measuring  electrode,  reference  electrode  and  neutral electrode.   Further probes can be provided as an aid for the central unit.

Abstract: An apparatus for releasing locked components of a theft-deterrent device in-cludes a seat for receiving a component of the theft deterrent device that contains a clutch and a ferromagnetic anvil that is positioned by a spring to fore the clutch to apply pressure against an inserted pin that is anchored in another component of the device so as to restrain the pin from release from the clutch; and a magnet with a pole piece coupled thereto, with the magnet and the pole piece being disposed for movement between a protracted position and a retracted position. When the magnet and the pale piece are in their protracted positron the pole piece is disposed about the sides of the clutch-containing component and applies magnetic flux from the magnet that is directed to overcame the farce of the spring and reposition the ferromagnetic anvil to thereby relax the pressure applied against the gin by the clutch so That the pin-anchoring component can be released from the clutch-containing component. The magnet and the pole piece are forced into their protracted position by a spring; and a flange is attached to the pole piece for enabling the magnet and the pole piece to be moved to their retracted position by applying pressure against the flange to overcome the force of the spring. When the magnet and the pole piece are in their retracted posi-tion, the attraction between the magnet and the anvil is less and the sides of the clutch-containing component are exposed so that the clutch-containing component can easily be gripped at its sides and removed from the seat. Also, when the magnet and the pate piece are in their retracted position, the releasing apparatus does not then enable the pin-anchoring component to be released from the clutch-containing component;  and the releasing apparatus further includes a lock for locking the magnet and the pole piece in their retracted position to prevent unauthorized use of the releasing apparatus.

Title: Heat exchanger and method of assembly thereof
Inventor: DERISI JOSEPH F
IPC: F28F9/18
Filed: 1992-01-29
Abstract: A method of affixing a plurality of tubes having oval ends into a plurality of corresponding oval openings in the header wall of a heat exchanger in which the wall has an inner, liquid-facing side and an outer, air-facing side. The oval ends of the tubes are sized such that the minor diameter of the tube ends is greater than the minor diameter of the header openings and the major diameter of the tube ends is less than the major diameter of the header openings, the circumference of the tube ends and the header openings being substantially equal. The tube ends are inserted into corresponding openings in the header wall whereupon the minor diameter of the tube ends is reduced and the major diameter of the tube ends is increased to create a substantially fully contacting fit around the circumference with said header openings. Ends of the tubes are welded to corresponding collar openings in the header wall, such that the tubes extend toward the air-facing side of the wall, to form a plurality of welded tube-to-header joints. Flux is applied by spraying or the like to the air-facing side of the tube-to-header joints. Thereafter, a lead/tin or other molten solder is applied to the liquid-facing side of the tube-to-header joint by dipping or wave solder techniques and flowed into any voids in the welded joints to substantially seal the joints against leakage of liquid.      Only those joints having potential liquid leaking voids receive the solder - sound, liquid-tight welded joints axe not solder sealed.

Patent CA-2072057-A1 (CA)
Title: Compression device
Inventor: DYE JOHN F
IPC: A61H1/02
Filed: 1992-06-23
Abstract: This invention relates to venous blood flow in a patient's limb which is promoted by repeating a cycle of sequentially applying compressive pressures against a patient's limb through means of a flexible, pressurizable sleeve having pressure chambers progressively arranged along the limb in relation to the patient's heart. Specifically, the pressure chambers from the distal to proximal are pressurized until they are at their appropriate pressures so as to collapse the veins in the limb.      At the end of the mast proximal compression, a foot chamber is compressed at a substantially higher pressure than the other chambers to force a bolus of blood from the foot into the limb causing the collapsed veins to open, the support of the chambers minimizing distention of the veins and enhancing the transmitting of blood up the limb.
