Patent CA-1284604-C (CA)
Title: Replenishable self contained breathing apparatus
Inventor: LAMBERT WILLIAM M
IPC: A62B7/00
Filed: 1987-02-20
Granted: 1991-06-04
Abstract: ABSTRACT A high pressure breathing gas  transfer system  is provided where high pressure air from a tank of one SCBA, or a central storage supply, can be quickly transferred directly into the high pressure air tank of a second SCBA.    The  transfer  process,  between  two  SCBA's,  is  accomplished  by attaching  a high  pressure  conduit  line  between  two  quick connect  check valves situated on the high pressure sides of the SCBA's.  The high pressure transfer line has a quick connect coupling attached to each end to enable connection to the check valves.   After the line  is attached,  a lever is depressed on one of the couplings  to  open the donor check valve.   High pressure air then flows out of the donor tank and  forces  the check valve open on  the  donee tank.   The air  transfer continues  until  the  internal pressure of the two tanks is equalized and the donee tank has received half of the air that was initially inside the donor tank.   Because the air is transferred on the high pressure side of the regulator,  the system may be used  to  accomplish buddy-breathing  between  two  SCBA users  in emergency situations, without interfering with the normal breathing operation of the SCBA's.

Title: Recovery of carbon dioxide from fuel cell exhaust
Inventor: HEALY HERBERT C
IPC: H01M8/04
Filed: 1987-12-08
Granted: 1991-11-05
Abstract: Abstract Recovery of Carbon Dioxide From Fuel Cell Exhaust A gaseous mixture of hydrogen and carbon dioxide is used as the fuel cell fuel or anode gas, and air is used as the oxidant or cathode gas in a nonalkaline fuel cell power plant.  In feeding the fuel gas through the anode side of the fuel cell, hydrogen is removed during the electrochemical reaction and the fuel gas which is exhausted from the anode side has a much higher proportion of carbon dioxide to hydrogen than the entering fuel gas.  The fuel gas exhaust is fed through a carbon dioxide absorber to remove carbon dioxide from the fuel exhaust.  The carbon dioxide is recovered from the absorber for useful purposes and the hydrogen gas leaving the absorber is dewatered and burned in a reformer.  Carbon dioxide emissions from the power plant are thus greatly reduced benefiting the environment.

Title: Drawing apparatus in a press
Inventor: KALETKA MARTIN
IPC: B21D24/08
Filed: 1988-01-22
Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE   A drawing apparatus in a press for holding the sheet metal part during the drawing and for the ejection thereof.          Additionally, blocking devices are provided which prevent the ejection of the sheet metal draw part at the same time with the upward movement of the press ram.  Each blocking device is thereby to be rendered selectively operable or inoperable.  A continuous flow of the hydraulic liquid is to be precluded during the inoperative condition of the blocking device.  The blocking device consists of a pressure cylinder, of a pressure piston which is displaceably movable on the piston rod displaceable by the draw cushion, and of a compression spring for the displacement of the pressure piston in the ejection direction.  The pressure space formed above the pressure piston is selectively pressureless for the inoperative condition, respectively, adapted to be acted upon with controlled pressure for the operative condition of the blocking device.  The arrangement enables, on the one hand, the operation of a press and especially of a transfer press with large stroke numbers; with the latter without the operation of the transfer device effecting the transfer movement of the sheet metal draw parts, on the other, the operation with reduced stroke number of the press under utilization of the blocking device.

IPC: H01R24/58
Filed: 1988-02-03
Granted: 1991-08-13
Abstract: Abstract of the Disclosure A jack module having a relatively thin substantially rectangular dielectric housing having collared plug receiving apertures on one end thereof.  The housing has a mounting bar parallel with said end, and the mounting bar has a plurality of slots perpendicular with the end.  A plurality of metal strips each having tabs extending from opposing edges are secured in a predetermined substantially parallel arrange-ment by inserting the tabs on one edge into said mounting bar and engaging a dielectric retaining bar with slots cor-responding to the tabs on the opposite edges over the metal strips.  Lifters having one end rotatably engaging the housing have opposite ends extending between metal strips to hold them in a predetermined alignment.  Upon insertion or removal of plugs from said plug receiving apertures, the metal strips are permitted to move laterally with the lifters. At least some of the metal strips are pretensioned and have curves for electrically contacting each other in a predeter-mined arrangement, the arrangement being changed by inserting plugs through the plug receiving apertures to move predeter-mined ones of said metal strips in the lateral direction. The opposite ends of the metal strips extend beyond the housing and having terminals adapted for connecting to an electrical circuit.  A metal plate engages the housing and attaches over the metal strips.  The metal plate not only shields the metal strips but also has extensions which ground to plugs inserted through said plug receiving apertures.

Title: Electromagnetic contactor with lightweight wide range current transducer with sintered powdered metal core
Inventor: ENGEL JOSEPH C
IPC: H01F3/14
Filed: 1988-02-17
Granted: 1992-09-22
Abstract: A B S T R A C T          ELECTROMAGNETIC CONTACTOR WITH LIGHTWEIGHT              WIDE RANGE CURRENT TRANSDUCER WITH  SINTERED POWDERED METAL CORE            A  contactor  utilizes  a  non-saturating current transformer for sensing the amount of current flowing in the electrical conductor connected to the contactor.  The current  sensor  is made of homogeneous sintered powdered metal  having  evenly  distributed  microscopic  air  gaps therein  which  increase  the  reluctance  of the  magnetic circuit but resist the influence of stray magnetic flux.          This increased reluctance prevents magnetic saturation over a wide range of input current and allows the secondary of the transducer to produce a voltage which is proportional to  the derivative  of the primary  current,  that  is  the current being sensed by the transducer.  The aforementioned voltage is linearly proportional to the derivative of the current over a wide range of primary current values.  This voltage is integrated to produce an output signal which is directly proportional to the aforementioned primary current over the wide range of current values.

The mean time delay of each output (time to reach the peak) is different for each of the modification unit output signals. The outputs of the signal modification units are applied to the input interconnection unit wherein connections are made in accordance with the sequences that are to be recognized.
