Title: Sexual sterilisation device
Inventor: FILSHIE GILBERT M
IPC: A61F6/20
Filed: 1986-07-10
Granted: 1991-08-13
Abstract: ABSTRACT         A sexual sterilization device in the form of a clip is designed to prevent, as far as possible, failure due to incorrect latching of an upper jaw underneath the lip of a lower jaw by dimensioning the upper and lower jaws such that considerable deformation of the upper jaw is required before correct latching can occur.

Abstract: ABSTRACT OF THE DISCLOSURE         Factor VIII:C deficiency in a hemophilic mammal may be bypassed by infusion of a synergistic mixture of a phospholipid and Factor Xa so that the cascade process of blood  clotting may  continue.   The  proportions  of phospholipid and Factor Xa in the mixture are critical as too little Xa has no effect while too much is toxic (thrombogenic).  Infusion of the phosphilipid-Factor Xa mixture into normal mammals enhances the natural clotting rate and provides a method for rapidly controlling bleeding in emergency situations.

Title: Method for concentrating surfactant from a brine solution
Inventor: BRAGG JAMES R
IPC: C09K23/08
Filed: 1986-08-28
Granted: 1991-06-04
Abstract: Abstract A method is disclosed for concentrating surfactant in an aqueous solution.  The method comprises adding to the solution a component incompatible with the surfactant, such as a water-soluble polymer, thereby displacing the surfactant from the aqueous phase of the solution.  The component remains in the aqueous phase and the surfactant goes into a surfactant-rich phase.  The surfactant-rich phase can then be separated from the aqueous phase by conventional separation devices or techniques.  This method is particularly applicable to concen-trating surfactant recovered from a reservoir following an enhanced oil recovery process employing surfactant.  The method may be practiced in the field or off-site.

Abstract: A data bearing card having first contacts connected to an integrated circuit on the card is read and confiscated if invalid or bogus. The card is translated in a first direction from an admission chamber to a reading station having second contacts adapted to engage the first contacts so data signals can be coupled between the integrated circuit and a data processor. After data stored in the integrated circuit have been read through the contacts the card is fed in a second direction of travel from the reading station back toward the admission chamber until the card has been completely extracted from the reading station. If the card is bogus, the reading station pivots to open a path for the card to a confiscation bin located beneath the reading station. The bogus card is then fed in the first direction into the confiscation bin. The contacts are cleaned because they rub on each other as a result of the reading station and the second contacts thereon being pivoted and translated across the first contacts in response to the card being inserted into the reading station.

Abstract: (Case No. 8445) ABSTRACT OF THE INVENTION   A control method for a dual-cylinder moisture removal apparatus of a pneumatic system is taught.  The control method places a limitation on the time for drying of moist air in a drying cylinder.  The drying of moist air in one drying cylinder and the regeneration of the absorbent used to dry moist air in a second cylinder are alternated at each predetermined time.  When the air compressor is stopped each drying cylinder is switched to a reverse position to the position it occupied just prior to the stopping of the air compressor.  Furthermore, when the air compressor resumes operation, the position of each drying cylinder is maintained in the position it occupied just before resumption of operation of the air compressor.

Granted: 1992-09-15
Abstract: A B S T R A C T     A weedless fish lure has an elongated spoon-shaped body defining  a  bulbous  outer  surface  on  one  side  of  a complementarily-shaped recess on the other side. The body has a generally  longitudinally-extending  slot,  and  at  least  one resilient hook mounted within the spoon-shaped body recess. The hook has  a shank portion at one end and extends  therefrom through a medial portion to a pointed portion at the other end.         The  shank  portion  is  secured  to  the  spoon-shaped  body  to position the pointed end portion adjacent the slot so that the pointed end portion is capable of frictional engagement with an end of the slot remote from the shank portion to retain the pointed end portion substantially wholly within the recess with the hook in a resiliently   deflected condition in which the medial portion projects from the recess on the other side of the  body.  The  pointed  end  portion is  capable  of  movement through the slot so as to project in a fish catching manner from the bulbous outer surface of the body when pressure is applied by the mouth of the  fish to the projecting medial portion in a direction to overcome the frictional engagement and cause the resiliency of the hook to spring the pointed end portion through the slot to a fish catching position.

Title: Magnetic bias coil of a magneto-optical recording apparatus
Inventor: ICHIHARA JUNICHI
IPC: G11B11/105
Filed: 1988-04-08
Granted: 1992-08-04
Abstract: ABSTRACT             The electromagnetic coil for applying a magnetic bias field on the recording bit of a magneto-optical recording disk apparatus is provided with a yoke made of soft magnetic material, such as soft iron.  The yoke surrounds the coil's outer round side as well as the coil's flat side remote from the disk side.  The light beam or the optical system is arranged in an opening on the yoke on the coil's flat side.  The yoke reduces the magnetic resistance of the coil, thus increases the magnetic field intensity at the recording bit which requires a magnetic field intensity over a certain level.  Consequently, the required magnetic field intensity is achieved with less coil current, in other words, within a reasonable range of the coil's temperature rise.
