Title: Method of producing high molecular weight sodium hyaluronate by fermentation of streptococcus
Inventor: NIMROD ABRAHAM
IPC: C12Q1/14
Filed: 1986-01-17
Granted: 1995-07-04
Abstract: A novel mutant microorganism Streptococcus zooepidemi-cus HA-116 ATCC 39920, has been produced.  The microor-ganism produces large amounts of high molecular weight hyaluronic acid.   The invention provides a method of obtaining such microorganisms.            The invention also concerns a method of obtaining sodi-um hyaluronate which comprises growing with vigorous agitation a microorganism of the genus Streptococcus under  appropriate  conditions  in  a  suitable  nutrient medium containing a sugar component as a carbon source. The sugar component is present in a substantially con-stant concentration between 0.2 and 10 grams per liter. The  medium  has  a  substantially  constant  pH  between about 6.0 and 7.5 and includes a substantially constant magnesium ion concentration above 0.05 grams per liter. The sodium hyaluronate excreted into the medium by the organism is purified using methods involving precipa-tion,  redissolving and reprecipating the hyaluronate. Composition of sodium hyaluronate which are character-ized by an absence of pyrogenicity and skin irritation are obtained.

Title: Power supply associated with ac line relay switch

Filed: 1987-10-16
Granted: 1991-04-16
Abstract: RCA 82,161 POWER SUPPLY ASSOCIATED WITH AC LINE RELAY SWITCH     Abstract of the Disclosure A relay switch in an ac main line has a dc-powered amplifier for applying amplified control sensor signals to the control circuit of the relay switch.  To provide dc power for the amplifier when the relay switch main controlled current conduction path is conductive, a current transformer primary winding is arranged in series with that path, and the voltage appearing across the secondary winding is rectified.  To provide dc power for the amplifier when the relay switch main controlled current conduction path is non-conductive, an open-circuit voltage related to that appearing across the open-circuit non-conductive path is rectified.  To permit the use of one rectifier for developing dc power for the amplifier it is advantageous to apply the open-circuit voltage to the secondary winding of the current transformer through a dc-blocking capacitor with sufficient ac impedance to restrict ac flow across the open-circuit relay switch path.

Abstract: LOADING COMPENSATION IN CYCLOMETER REGISTER   ABSTRACT OF THE DISCLOSURE     A cyclometer register in An electric watthour meter includes a free counterweight for producing a kinetic-energy kick for advancing superior cyclometer drums.  A drum counterweight, affixed to the units cyclometer drum, is disposed 180 angular degrees out of phase with the are  counterweight.

A harmonic counterweight rotates at twice the angular rate of the units cyclometer drum and reflects one-quarter of the moment of the free counterweight back to the driving elements.  The harmonic counterweight reduces further the maximum moment as seen by the driving elements and also increases the minimum moment to that the variability in moment is reduced, thereby enabling an offsetting constant increase in meter torque and reducing metering error.

Abstract: FREE FALLING LATCH PLATE ASSEMBLY            Abstract of the Disclosure According to the invention an improved latch plate assembly for a continuous loop single retractor seat belt system includes a housing having a base wall with flanges slotted to slidably mount a lock bar.  The housing is oriented with the flanges facing toward the occupant torso and the belt being routed through the space between the base wall and the sliding bar so that when the belt is stored in the generally vertically extending position between the upper and lower anchors, the belt extends in a minimally convoluted path through the latch plate thereby permitting gravity induced sliding movement of the latch plate along the belt toward the lower end of the belt. The housing is further characterized by an integral abutment structure adapted upon migration of the lock bar along the slot with the occurrence of generally colinear orientation of the lap and shoulder belts upon buckling of the belt to introduce a substantially convoluted path of belt through the latch plate and trap the belt between the sliding bar and the flange structure  so that the travel of the belt through the latch plate is effectively prevented at least in the direction which would extend the length of the lap belt portion.
