Title: Overload apparatus
Inventor: HANKS JAMES V
IPC: F16D25/08
Filed: 1988-03-10
Granted: 1992-06-30
Abstract: TITLE Overload Apparatus ABSTRACT OF THE DISCLOSURE    An overload apparatus is shown in its preferred form according to the teachings of the present invention as an overload single position clutch (A) having a drive ring (52) which is reciprocated by springs (78) and by a cylinder (10) slideable on a piston (22) by fluid pressure.  The drive ring (52) includes a multiplicity of ball receiving cavities (58).  A sheave mount (96) is further provided including an integral interface disc (99) having a multiplicity of ball carrying cavities (100a).  Balls (100b, 102b, 104b, 106b, 108b) are captured within the ball carrying cavities (100a) by a ball cage (88) secured to the mount (96).  The ball carrying cavities (100a) have diameters less than the balls (100b-108b) and a shape and size such that the balls (100b-108b) do not touch the closed ends or sidewalls of the cavities (100a) but rather the open ends (109) form seats for the balls (100b-108b).  According to the teachings of the present invention, the ball carrying cavities (100a) have diameters greater than the diameters of the ball receiving cavities (58) to predispose the balls (100b-108b) to cam out of the ball receiving cavities (58) in the event of reaching a torque overload level.  In another aspect of the present invention, the balls (100b-108b) are captured in the ball carrying cavities (100a) by constant diameter apertures (100d, 102d, 104d, 106d, 108b) formed in a carrier ring (168) and a retaining plate (170), with the aperture diameters (100d-108d) of the carrier ring (168) being generally equal to that of the balls (100b-108b) and with the aperture diameters (100e. 102e, 104e, 106e, 108e) of the retaining ring (170) being less than that of the balls (100b-108b).

Abstract: Abstract An apparatus and process are described for treating molten metal.  The invention comprises:  (a) a heated vessel having inlet and outlet means for the continuous flow of molten metal downwardly through the vessel, (b) a perforated plate extending horizontally across the vessel dividing it into an upper treatment section and a lower treatment section, this plate forming an intermediate treatment section, and (c) a device for injecting gas in the form of small discrete bubbles into the metal in the lower treatment section, this device comprising a hollow rotatable shaft extending downwardly through an opening in the plate with drive means coupled to the upper end of the shaft, a vaned rotor fixedly attached to the lower end of the shaft within the lower treatment section, with one or more passageways within the rotor for conducting gas from the interior of the shaft to the metal in the lower treatment section.  When the gas is discharged through the rotor and the rotor is rotated, the gas is injected into the metal in the form of small discrete bubbles which are uniformly dispersed within the lower treatment section.  In a preferred embodiment of the invention the gas bubbles move from the rotor upwardly and outwardly in a generally conical pattern to be distributed across the bottom of the perforated plate and pass upwardly through the perforations thereof.

Patent CA-1326805-C (CA)
Inventor: BROOKMAN MICHAEL J
IPC: A62B17/04
Filed: 1988-08-09
Granted: 1994-02-08
Abstract: ABSTRACT        The instant invention is a respiratory system for use on aircraft or similar compartments to temporarily prevent asphyxiation and suffocation due to the presence of smoke, toxic gases and/or noxious gases resulting from aircraft fire or similar such.  The respiratory system consists of a small dropout package containing a protective hood for deployment to enclose the head of the passenger to improve the passenger's vision in the smoke, a protective breathing mask for enclosing the mouth and nose of the passenger in order to provide breathable air and a dual air supply system. The respiratory system provides a connection to a fresh, breathable air supply from the aircraft's emergency air source and provides a chemical air purifier preferably including a wet scrubbing system for purifing cabin air of contaminants to supply additional breathable air. The respiratory system is disengageable from the aircraft's emergency air source for evacuation.
Patent CA-1339027-C (CA)
Title: Synthetic peptides, antibodies directed against them, and the use thereof
Inventor: PELZER HERMANN
IPC: C07K17/02
Filed: 1988-08-18
Granted: 1997-03-25
Abstract: The invention relates to synthetic peptides which have amino acid sequences which correspond, in whole or in part, to the amino acid sequence of prothrombin and are anti-genic, to the use thereof for the immunization of an ani-mal and for the purification of specific antibodies, to antibodies against these peptides, and to the use of the antibodies for the determination of the fragments F2/F1+2. The antibodies hitherto used for the determination of the content of the fragments F2/F1+2 have been induced by immunization with natural, highly purified prothrombin fragments F2/F1+2.  The isolation of these prothrombin fragments is elaborate and costly, and the antibodies gene-rated therewith show cross-reactions with intact prothrom-bin.  Used for the immunization according to the invention are synthetic peptides which have amino acid sequences which correspond, in whole or in part, to the amino acid sequence of prothrombin and are antigenic.  The resulting antibodies react specifically with the antigen used for the immunization;  if the peptides contain the carboxyl-terminal amino acid sequence of the fragments F2/F1+2 resulting after cleavage of the prothrombin molecule with factor Xa, then the antibodies generated react specific-ally with the fragments F2/F1+2 but not with intact natural prothrombin, so that information can be gained about the degree of activation of prothrombin.

Title: Three terminal remotely controlled spdt antenna switch
Inventor: SCHULTZ CHALRES A
IPC: H01Q21/00
Filed: 1988-12-16
Granted: 1992-09-01
Abstract: ABSTRACT       An antenna switch (302) includes a radio terminal (R) and first and second antenna terminals (A1 and A2).  When the second antenna terminal (A2) is unterminated, the radio terminal (R) is coupled to the first antenna terminal (A1).  When the second antenna terminal (A2) is connected to a remote antenna system (304), the switch automatically couples the radio terminal (R) to the second antenna terminal (A2).  Thus, the switch does not require a separate control terminal (C) and control signal to switch between the first and second antenna terminals.  Instead, the switch is controlled by the presence or absence of a DC current at the second antenna terminal (A2).  The remote antenna system includes a remote antenna (308) and a low pass filter (310) coupled between the remote antenna and ground.  An alternate embodiment is described which includes a DC amplifier (402).

Title: Polarization-maintaining optical fiber for coupler  fabrication
Inventor: OLSON GRIEG A
IPC: G02B6/28
Filed: 1989-08-17
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE           Polarization-maintaining coupler is made by a biconically-tapered-fused process from two short lengths of an optical fiber, each having a small, oval stress-applying region that substantially contacts the core.  The area of the stress-applying region of the optical fiber is less than 10 percent, preferably less than 2 percent, that of the optical fiber and preferably is contiguous with the core.  Couplers of highest quality are made from quartz glass fibers having a birefringence between 1 and 3 x 10-4.  It is believed that the principal axes of the oval stress-applying regions of those couplers of highest quality have been collinear or parallel.  To permit a coupler to be handled, it can be mounted on a quartz glass substrate with the coupler suspended in air and then potted in a cured elastomer.
